There are many other proposed intervals: Patil and Kulkarni list and evaluate 19 different sugges tions from the literature!. The exact intervals can be overly broad for very small values of k, many of the other approaches try to shrink the lengths, with varying success. If both k and time are single values the result is a vector of length 2 containing the lower an upper limits. If k is a matrix or array, the result will be an array with one more dimension; in this case the dimensions and dimnames (if any) of k are preserved.

The default is to use the exact conditional likelihood, a commonly used approximate conditional likelihood is provided for compatibility with older software. Proving this is a nice homework exercise for a PhD statistics class; not too hard, but the fact that it is true is surprising. When a well tested Cox model routine is available many packages use this trick rather than writing a new software routine from scratch, and this is what the clogit routine does. The clogit routine creates the necessary dummy variable of times (all 1) and the strata, then calls coxph. If a particular strata had say 10 events out of 20 subjects we have to add up a denominator that involves all possible ways of choosing 10 out of 20, which is 20! Gail et al describe a fast recursion method which partly ameliorates this; it was incorporated into version 2. The computation remains infeasible for very large groups of ties, say 100 ties out of 500 subjects, and may even lead to integer over? Most of the time conditional logistic modeling is applied data with 1 case + k controls per set, in which case all of the approximations for ties lead to exactly the same result.

According to the Japan Esophageal Socie among these task forces (see Appendix 1). Moreover, several studies have shown higher invasion carries a higher risk (up to 46%) [60?68].

Most perforations were managed con servatively in these studies, with no death attributed to perfora tion. As a general rule, if large vessels are observed they should be coagulated before pro ceeding with the dissection. If a major bleed occurs, prompt he mostasis must be performed before proceeding, in order to pre vent there being more than one bleeding spot. Bleeding can initi ally be controlled with the knife in coagulation mode and if this fails then a coagulation forceps should be used. The use of hemo clips during the procedure should be avoided in the dissection area since this may compromise further dissection. If a bleed is not controlled by the coagulation forceps then dissection around the bleeding point should be done before placing a hemoclip, in order to fully expose the bleeding point and to enable further and complete dissection of the lesion. Visible vessels should be routi nely coagulated after dissection since this has been shown to sig nificantly reduce the risk of delayed bleeding [137]. If delayed bleeding does occur, this should be handled using the standard Pimentel-Nunes Pedro et al. Nevertheless, others were managed conservatively with or without endoscopic even in these cases surgery remains an option with surgery re clipping [138].

This is an important decision shinee symptoms mp3 safe sinemet 300mg, and you should take the time to think about all of the choices. The main factors in selecting treatment options for lung carcinoid tumors are the size and location of the tumor, whether it has spread to lymph nodes or other organs, and if you have any other serious medical conditions. A second opinion may provide more information and help you feel more certain about the treatment plan that is chosen. You should be referred to a thoracic or cardiothoracic surgeon who will discuss the surgical options. The type of operation will depend on a number of factors, including the size and location of the tumor and whether you have any other lung problems or serious diseases. It is usually necessary to remove some normal lung tissue along with the tumor, but surgeons try not to remove any more normal tissue than they need to . To treat central carcinoids of a large airway, the surgeon may do a sleeve resection. If you think of the large airway with a tumor as similar to the sleeve of a shirt with a stain an inch or two above the wrist, the sleeve resection would be like cutting across the sleeve above and below the stain and sewing the cuff back into the shortened sleeve. If it is not possible to do a sleeve resection because of the size of the tumor and its exact location in a large airway, the surgeon will usually do a lobectomy (remove an entire lobe). Less often, it may be necessary to remove two lobes or, rarely, remove the entire left or right lung (this operation is called a pneumonectomy). Carcinoids found at the edges of the lungs away from the large airways, called peripheral carcinoids, are usually treated by lobectomy. If the tumor is very small, the surgeon may remove a wedge-shaped piece of the lung in an operation called a wedge resection. This is important because about 10% of typical carcinoids and 30% to 50% of atypical carcinoids will have spread to lymph nodes by the time they are diagnosed. Not removing these nodes might increase the risk of the carcinoid tumor spreading even farther, to other organs. Removing the lymph nodes also provides some indication of your risk of having the cancer come back. If you have other medical problems, such as severe heart disease, you also may not be able to have curative surgery. If this is the case, palliative procedures, such as removing most of the tumor through a bronchoscope or vaporizing most of it with a laser, can be helpful. These treatments can relieve symptoms caused by blockage of airways, but they cannot cure the cancer and are recommended only if you cannot have surgery to completely remove the tumor. Patients who are treated with these procedures often also have external radiation or radiation given through the bronchus (see our document on radiation therapy). Recently, a less invasive procedure for treating early stage lung cancer has been developed. A tiny video camera can be placed inside the chest cavity to help the surgeon see the tumor. Most experts recommend that only tumors smaller than 4 to 5 cm (about 2 inches) be treated with this method. It is important, though, that the surgeon performing this procedure be experienced since it requires more technical skill than the standard surgery. Chemotherapy Chemotherapy uses anticancer drugs that are injected into a vein or a muscle or taken by mouth. These drugs enter the bloodstream and reach all areas of the body, making this treatment useful for some types of lung cancer that have spread or metastasized to organs beyond the lungs. Chemotherapy is generally used only for carcinoid tumors that have spread to other organs, are causing severe symptoms, and have not responded to other medications. Some of the chemotherapy drugs used in this situation include streptozotocin, etoposide, cisplatin, cyclophosphamide, 5-fluorouracil, doxorubicin (Adriamycin), and dacarbazine. Several chemotherapeutic drugs are sometimes used together to treat metastatic carcinoid tumor, often in combination with other types of medications. Chemotherapy drugs kill some cancer cells but can also affect some of the normal, healthy cells in your body, causing side effects. Rapidly growing cells, such as the blood-producing cells of bone marrow, cells of hair follicles, and cells lining the mouth, are particularly sensitive to chemotherapy. Possible side effects include: q Nausea, vomiting, and decrease in appetite q Temporary loss of hair q Mouth sores q Increased risk of infections (because of low white blood cell counts) or bleeding (because of low blood platelet counts) q Fatigue If you have side effects, your cancer care team can suggest steps to ease them. Sometimes changing the dosage or the time of day at which you take your medications can reduce side effects. Patients should discuss with their doctors whether the side effects they experience are worth the small chance that they will get better. Other Drugs for Treating Carcinoid Tumors Several medications are available for controlling symptoms of carcinoid syndrome (problems arising from release of substances produced by some of these tumors and recognized through blood and urine tests) in patients with metastatic carcinoid tumors. It is very helpful in treating the flushing (skin redness and feeling hot), diarrhea, and wheezing from carcinoid syndrome. Sometimes octreotide can temporarily shrink carcinoid tumors, but it does not cure them. Octreotide must be given at least twice daily while lanreotide can be given every 10 days. Alpha-interferon is helpful in shrinking some metastatic carcinoid tumors and improving symptoms of carcinoid syndrome. Ask your doctor about them, or describe your symptoms to your doctor and ask about medications to control them. Radiation Therapy Radiation therapy uses high-energy radiation to kill cancer cells. Although most cases of carcinoid tumor are cured by surgery alone, if for some reason the patient is unable to have surgery, radiotherapy may be an option. External beam radiation therapy is the type of radiation used most often for lung cancer. Radiation therapy is not usually very effective against most lung carcinoid tumors and is seldom used. The main side effects of lung radiation therapy are fatigue (tiredness) and mild temporary, sunburn-like skin changes. If high doses are given, radiation damage to normal lung tissue can cause scar tissue formation, trouble with breathing, and increased susceptibility to infection. Doctors have used this drug effectively in patients who have advanced carcinoid tumors, and about half the patients showed improvement. Complementary and Alternative Therapies If you are considering any unproven alternative or complementary treatments, it is best to discuss this openly with your cancer care team and request information from the American Cancer Society or the National Cancer Institute. Some unproven treatments can interfere with standard medical treatments or may cause serious side effects. Clinical Trials the purpose of clinical trials: Studies of promising new or experimental treatments in patients are known as clinical trials. A clinical trial is only done when there is some reason to believe that the treatment being studied may be valuable to the patient. Researchers conduct studies of new treatments to answer the following questions: q Is the treatment helpful? Phase I clinical trials: the purpose of a phase I study with a new drug is to find the best way to give a new treatment and how much of it can be given safely. The treatment has been well tested in laboratory and animal studies, but the side effects in patients are not completely known. Doctors conducting the clinical trial will start by giving very low doses of the drug to the first patients and increasing the dose for later groups of patients until side effects appear. Although doctors are hoping to help patients, the main purpose of a phase I study is to test the safety of the drug. One group (the control group) will receive the standard (most accepted) treatment. Usually doctors study only 1 new treatment to see if it works better than the standard treatment, but sometimes they will test 2 or 3. The study will be stopped if the side effects of the new treatment are too severe or if one group has had much better results than the others. You will have a team of experts looking at you and monitoring your progress very carefully.

Purchase 110 mg sinemet mastercard

However treatment 3 degree heart block sinemet 110 mg low price, critics have suggested that the figure of 50% is not evidence-based and is perhaps biased. This study recommends an optimal 52% treatment rate figure using an evidence-based approach. An evidence-based estimate will allow more accurate planning of future radiotherapy services. A readily adaptable model of the type described in this paper will allow easy re-calculation should cancer incidence or treatment recommendations change in the future. The model can also be adapted for use in other populations that have differing distributions of cancers and stages at diagnosis such as in countries like India where cervical cancer is much more common than in Australia. However, the evidence-based radiotherapy utilisation estimate needs to be used in context with other indications of radiotherapy not considered by the model when planning radiotherapy. The model uses cancer incidence data on registrable cancers from the cancer registry to estimate demand. This does not account for patients with conditions that are treated by megavoltage radiotherapy but are not registered in the statutory notification of cancer incidence. In particular benign brain tumours and metastatic and complex non-melanomatous skin cancers may add appreciably to the demand for radiotherapy. There are currently no evidence-based estimates of the utilisation of radiotherapy for non registered cases. We examined actual radiotherapy activity rates for non registered cases as the next best solution. The William Buckland Cancer Centre, Victoria reported on the case mix and outcomes of 9838 patients treated at the centre between 1992 and 2002 (Table 1). The treatment of skin cancers, heterotopic bone, benign neoplasms and other non malignant conditions accounted for 12% of radiotherapy activity. A similar analysis of 16530 patients treated at the Queensland Radium Institute between 1992 and 1997 showed that the proportion of conditions treated by radiotherapy but not registered with the Cancer Registry was 11%. Some skin cancers may be treated by Kilovoltage equipment but in many centres electrons produced by linear accelerators is the only modality available to treat skin cancers. Prospective, longitudinal studies of appropriate, evidence-based use of radiotherapy are recommended to get a more accurate assessment. Table 1: Workload at the William Buckland Centre and at the Queensland Radium Institute according to registered and non registered conditions. William Year of treatment 92 98 98-99 99-00 00-01 01-02 All years Buckland Malignant 4762 1010 959 1169 1243. The data in Table 1 imply that each linear accelerator could treat 396 courses for registered malignancies and 54 for non-registered conditions. Those 396 courses would consist of 297 courses for patients who had never received radiotherapy and 99 courses for patients who had been treated before (assuming a 25% retreatment rate (5) which has been commonly reported as a reasonable benchmark) (see Table 2). Table 2: the distribution of treatment for a linear accelerator including treatment for non-registered conditions. Retreated registered cases Less 25% 297 In addition, the planning parameters that were used assume that the linear accelerators will be used at 100% capacity. They make no allowance for spare capacity to avoid long and increasing waiting lists (6). New equipment such as multileaf collimators and new techniques such as Intensity Modulated Radiotherapy have appreciably altered the capacity of linear accelerators to treat new cases. The radiotherapy utilisation trees that have been developed for each of the tumour sites are a diagrammatic representation of optimal evidence-based cancer care from a radiotherapy perspective. Epidemiological data from patterns of care studies will allow comparisons to be made between the actual rates of radiotherapy delivery and the evidence-based ideal rate. Further details can be ascertained by analysing the distributions of tumour stage, histology, age, performance status and other factors, in order to better define areas of discrepancy between the actual and ideal utilisation rates. Assessment of the impact of the changes on the overall recommended radiotherapy utilisation rate. The TreeAge software used to construct the radiotherapy trees can be readily used to change the overall model should there be changes in the incidence of certain cancers, a change in the stage distribution or a change in therapy recommendations based on clinical trials. For example, if another country with a very different cancer incidence profile were to use the model then the only requirement to recalculate the optimal radiotherapy utilisation rate would be to alter the incidence of each of the cancers. Similarly, a change in stage distribution of cancer due to the development of superior staging investigations (such as the impact that Positron Emission Tomography has had on non-small cell lung cancer staging), or following the introduction of a screening programme could easily be incorporated into the model. Throughout the course of this project, the methodology has been refined and improved upon. The radiotherapy utilisation tree model and methodology could be readily adapted to consider other treatments (such as surgery or chemotherapy) for cancer. It could also be used to plan other services if criteria were known for the use of a particular service. For instance, if we knew the factors that predict the need for palliative care referral or genetics review, then resource planning could be assisted, by calculating the optimal utilisation rate in a similar fashion to that described here for radiotherapy. This research has identified several potential future research projects in a number of different areas. A few of these general areas are discussed below: (a) Further utilisation tree constructions as discussed above, this methodology has been validated and has been approved by external reviewers as an appropriate approach to the research question. Therefore applying similar utilisation tree methodology to services such as surgery, chemotherapy, palliative care or genetics would be feasible and useful. In addition, other non oncological medical therapies could use similar methodology to assess the need for services and provide a guide for health planners. The methodology could also be used to study the proportions of patients who have benign diseases in whom radiotherapy would be considered appropriate. This model will also allow population projections to be used to calculate future radiotherapy need. The main data identified as being sub-optimal are areas of the tree that are near the terminal branches and those identified as having variable data in sensitivity analysis. More meaningful data, particularly longitudinal population-based data, would be valuable in the following areas: metastasis incidence with time and by stage and treatment for the more common cancers, the proportion of patients who develop metastases to organs other than bone and brain and the need for symptomatic control, patterns of metastatic spread with time and the proportion of patients who develop metastases of differing types, the proportion of patients who develop symptoms as an indication for palliative radiation treatment over time, performance status and how this changes with relapse and patient choice when two treatment modalities are considered similar in efficacy and are equally available. Therefore, the controversial clinical areas where clinical trials may make a substantial difference to the optimal radiotherapy utilisation rate can be identified. The main controversies identified in terms of their impact on the optimal radiotherapy utilisation rate are the role of radiotherapy (as opposed to observation or surgery) for localised prostate cancer and the role of radiotherapy for T4 colon cancer. Other areas of uncertainty which impact on the optimal utilisation rate are the following: the criteria for adjuvant radiotherapy for node-positive melanoma need to be better defined, the role of radiotherapy for positive margins post prostatectomy is to be better determined, the role of lymph node dissection for endometrial cancer and the role of surgery (versus radiotherapy) for localised bladder cancer also need further study. However, the tree does not assess whether the treatment intent would be palliative or radical, does not predict the number of fractions of treatment that would be evidence-based, nor the complexity of the patients care. Various models of complexity have been reported in the literature that might be used in future studies so that even more accurate predictions of radiotherapy workload could be performed. Beam and Isotope Radiotherapy A report of the Australian Health Technology Advisory Committee. A comparison of the evidence based utilisation of radiotherapy with current clinical practice. A comparison of the evidence based utilisation of radiotherapy with current clinical practice. Conclusions Conclusions this study has found that the proportion of all patients with registered cancers that should receive at least one course of megavoltage external beam radiotherapy during the course of their illness is 52. One-way and Monte Carlo sensitivity analyses show this estimate to be robust, despite the limitations of some data. This estimated optimal utilisation rate will assist in planning for radiotherapy resource needs. The optimal radiotherapy utilisation rate can function as a valuable benchmark against which patterns of care data may be compared. The methodology allows easy adaptation of the model to allow for future changes in treatment recommendations and/or tumour stage distribution. The methodology also provides an excellent framework that can be used to determine optimal utilisation rates for other oncological and non-oncological services.

Similarly symptoms 2 dpo generic 110 mg sinemet overnight delivery, the propagation of a phenobarbital dependent hepatocyte cell line (6/27/C1) was shown to be promoter-dependent, in that clonal expansion occurred only when phenobarbital was replaced by another liver tumour promoter in the culture medium (Kaufmann et al. Human hepatocytes were also refractory to these effects (Hasmall & Roberts, 1999). Male Sprague-Dawley rats fed a diet containing 1200 mg/kg phenobarbital for 3, 7, 14, 21, 30, 45, 60 or 90 days showed a 25% reduction in T4 concentration and an 80% increase in thyroid weight. In another study, a mitogenic response was found in rat thyroid only after 8 weeks of treatment with phenobarbital at 0. The effect of phenobarbital on thyroid function and biliary excretion of T4 was examined by giving male and female rats a diet containing phenobarbital to provide a target dose of 100 mg/kg bw per day for 2 weeks. Treatment of thyroidectomized rats with phenobarbital increased the plasma clearance of T4. Bile-duct cannulated pheno barbital-treated male rats showed a marked increase in hepatic uptake of [125I]T4 and a 42% increase in its biliary excretion, due mainly to increased excretion of T4 glucuronide. These effects were observed in both male and female rats, but the response was greater in males (McClain et al. No significant changes in serum T4 and T3 concentrations were observed, and the histological appearance of the thyroid was not affected. Thus, phenobarbital did not affect thyroid hormone metabolism or thyroid function in mice (Viollon-Abadie et al. The weight of the thyroid was significantly increased on day 16 and that of the liver on days 4 and 16. Mild to moderate thyroid follicular hypertrophy and moderate hepatocellular hypertrophy occurred in all phenobarbital-treated animals (Johnson et al. The animals received thyroid hormone replacement via implanted osmotic minipumps, which resulted in T4 and T3 serum concentrations similar to those in controls, and were then given phenobarbital in the diet at 1200 mg/kg for 10 days. Phenobarbital reduced the total T4 concentration on days 3?10 and that of free T4 on days 7?10 after minipump implantation, and decreased the total T3 concentration on days 7?10. In a study in intact male Sprague-Dawley rats, administration of a diet containing phenobarbital at 1200 mg/kg for 21 days resulted in a 1. Similar effects on thyroid hormone concentrations were observed in rats treated with an oral dose of 50?100 mg/kg bw phenobarbital daily for 7 or 14 days (de Sandro et al. A classic pattern of minor dysmorphologies has been described in children born to mothers treated with phenobarbital for epilepsy during pregnancy. This syndrome includes nail hypoplasia and a typical appearance produced by midfacial hypoplasia, depressed nasal bridge, epicanthal folds and ocular hypertelorism. In an earlier review, Dansky and Finnell (1991) found evidence that phenobarbital mono therapy was associated with malformations similar to those reported with hydantoins, suggesting a common biochemical pathway. They also noted that the risks appeared to be greater after treatment of women with epilepsy than treatment of women without seizure disorders. When compared with a matched control group, the exposed infants showed significant increases in the frequency of major malformations or growth retardation (15. Forty-six of 63 ascertained liveborn infants (seven cases were lost to follow-up and there were 12 spontaneous and one therapeutic abortions) were evaluated by a dysmorphologist. Of these, seven (15%) had facial features characteristic of anti-epileptic therapy and 11 (24%) had hypoplastic finger nails (Jones et al. In a prospective cohort study of the pregnancy outcomes of women being treated for epilepsy with anti-convulsant therapy, 72 infants were born to mothers who had received phenobarbital monotherapy during the first trimester (Dravet et al. This group comprised 12 infants with microcephaly, 44 who were not microcephalic and 16 unrecorded outcomes [odds ratio apparently not significant]. In a study of the risk of intrauterine growth delay in the offspring of mothers with epilepsy, prospective data on 870 newborn infants in Canada, Italy and Japan were pooled and analysed. A total of 88 infants were born to mothers who had received phenobarbital monotherapy. By logistic regression, the risk for small head circum ference was shown to be higher (relative risk, 3. Subsequent analysis showed statistically significant dose and concentration-dependent effects of phenobarbital on small head circumference. A study of the development of sexual identity was carried out among the offspring of mothers with epilepsy who had taken phenobarbital during the index pregnancy in the Amsterdam Academic Medical Centre between 1957 and 1972. The controls were an equal number of persons from the original pool of 222, matched for birth date, sex and maternal age. Three tests of psychosexual development were used: the Gender Role Assessment Schedule, the Klein Sexual Orientation Grid and the Psychosexual Mile stones in Puberty questionnaire. Exposed and control subjects did not differ with respect to gender role behaviour, although greater numbers of persons exposed prenatally to anticonvulsants reported past or present cross-sexual behaviour and/or sexual dysphoria (Dessens et al. The intelligence scores of adult men whose mothers had received phenobarbital during pregnancy and who had no history of a central nervous system disorder were measured. The population was drawn from the Danish Perinatal Cohort that was assembled in 1959?61 (Reinisch et al. A total of 114 exposed offspring and 153 controls were matched for a number of variables. Exposure to phenobarbital, especially during the last trimester, was associated with significantly lower verbal intelligence scores. The pheno barbital treatment consisted of administration of a 100-mg tablet daily during weeks 34?36 of gestation. The frequency of neonatal hyperbilirubinaemia was reduced in those exposed to phenobarbital. In a follow-up of 36% (719) of the 2003 children in one of the two geographical study areas at the age of 5. Pubertal development appeared to be affected, in that there was a trend for the pubertal stage to be delayed in the treated group. The boys showed significantly higher cognitive function as assessed by the Wechler Intelligence Scale. There was a trend towards a decreased incidence of intra cranial haemorrhage of any grade in the group given phenobarbital (22% versus 35%). The authors noted that the mode of action of this response is not clear but may be related to hypertensive peaks in the neonate. In a follow-up study, no adverse consequences on growth or in the McCarthy General Cognitive Index was seen in the phenobarbital treated offspring up to 3 years of age (Shankaran et al. The dose of phenobarbital was targeted to yield serum pheno barbital concentrations in the mother and infant of 15?17? In the 121 (32%) of 375 children who participated in the 2-year follow-up, a significantly lower Bayley mental developmental index was found in the treated group compared with the controls (104 versus 113). Backward regression analysis indicated the presence of five other covariates that were statistically significant, including maternal education and patent ductus arteriosis. A prospective study of 983 infants born to women with epilepsy in Canada, Italy and Japan indicated that the incidence of malformations in the infants of women who had not taken an anti-epileptic drug (n = 98) was 3. No specific pattern of malformations was identified after pheno barbital monotherapy. A paucity of work on the effects of exposure to phenobarbital in utero on pregnancy outcome was noted, the available evidence suggesting that the potency was less than that of other anti-convulsants, such as phenytoin and valproic acid. In a review of the literature, the influences of route of administration and dose on the nature of the adverse pregnancy outcome were emphasized (Middaugh, 1986). Studies in which injections were given that tended to result in plasma concentrations similar to those for therapeutic uses (5?20? Long-Evans rats were given phenobarbital by oral gavage at a dose of 40 mg/kg bw per day during the first 7 days of lactation to investigate whether neonatal exposure altered the sensitivity to carcinogens later in life. In other male offspring of the same age, neonatal exposure to phenobarbital caused a 2. One of 171 fetuses at the low dose, 6/155 at the high dose and none of the controls had cleft palate [not noted as significant unless pooled over all phenobarbital-treated litters]. No dose related effects on maternal or fetal body weights or on fetal viability were observed (Sullivan & McElhatton, 1975). There were no effects on fetal growth, viability or other mal formations (Fritz et al.

No significant difference was seen in the incidence of hepatocellular adenomas between untreated yellow and agouti males at terminal sacrifice symptoms of a stranger order sinemet once a day. Sodium phenobarbital increased the incidence of hepatocellular adenomas in yellow male mice from 23/193 (12%) in controls to 105/192 (55%) in treated animals. The inci dence of hepatocellular adenomas in treated yellow males was significantly greater than that in treated agouti males (105/192 versus 46/192) [p value not given in table or text]. Treatment with sodium phenobarbital decreased the incidence of carcinoma significantly (p = 0. Groups [initial numbers not specified] of male germ-free (Gf) and conventional (Cv) C3H/He mice, 6 weeks of age, were given an irradiated basal diet containing phenobarbital [purity not specified] at 200 mg/kg until 12 months of age. The inci dence and number of liver nodules per mouse in treated Gf mice was significantly higher than that in untreated Gf animals (67% (14/21) versus 30% (42/139); p < 0. The incidence of liver tumour nodules and their average number in phenobarbital-treated Cv mice were also signifi cantly higher than those in untreated mice (100% (31/31) versus 75% (42/56); p < 0. Groups of five control and five treated mice of each strain were killed at 5, 30, 40 and 80 weeks, and two additional groups of 20 control and 20 treated animals of each strain were killed at 60 weeks. In addition, 25 animals of each strain were treated for 60 weeks and then returned to the control diet, and the survivors were killed at the end of the respective experiments. Nodules were seen in both treated and control C3H/He mice as early as 30 weeks, and were numerous in both these groups at the final kill at 91 weeks. In control animals, all the nodules were of the basophilic type, while in the treated group both basophilic and eosinophilic nodules were found. By 91 weeks, 80% (16/20) of the control animals and 40% (8/20) of the treated animals bore basophilic nodules, while all the treated animals and none of the controls (0/20) also developed multiple eosinophilic nodules (20/20). C3H/He mice given sodium phenobarbital for 60 weeks and then returned to the control diet bore fewer nodules at 91 weeks than treated mice killed at 60 or 91 weeks. The authors concluded that the two strains of mouse reacted in a qualitatively similar manner to administration of sodium pheno barbital, although they showed considerable quantitative differences in terms of the time and number of nodules (Evans et al. At 6 months, the incidence of hepatocellular adenomas was 5/10 in c-myc mice fed phenobarbital, 0/5 in wild-type mice and 0/10 in c-myc mice on basal diet. At 8 months, the incidence of hepatocellular adenomas was 8/10 in c-myc mice fed phenobarbital, 0/5 in wild-type mice and 2/10 in c-myc mice on basal diet. At 10 months, the incidence of hepatocellular adenomas was 10/10 in c-myc mice fed phenobarbital, 0/5 in wild-type mice and 4/12 in c-myc mice on basal diet. At 8 months, hepatocellular carcinoma occurred only in c-myc mice fed phenobarbital (2/10). At 10 months, the incidence of hepatocellular carcinomas was 4/10 in c-myc mice fed phenobarbital, 0/5 in wild-type mice and 1/12 in c-myc mice fed basal diet. All mice fed phenobarbital showed a significant increase in absolute and relative liver weights; no difference in the liver weights was seen between heterozygous and wild type mice. There were no tumours in mice of either sex or genotype treated with phenobarbital, although the livers of all animals showed moderate to marked centrilobular hepatocellular hypertrophy (Sagartz et al. Rat: Groups of 34?36 male and female Wistar rats, 7 weeks of age, were given drinking-water containing 0 (control) or 500 mg/L sodium phenobarbital up to 152 weeks of age, when the survivors were killed. No significant differences were found in body-weight gain or survival between groups. Sodium phenobarbital induced hepato cellular adenomas late in life, the first tumour being diagnosed at 77 weeks. The average age at death of rats with liver tumours was 132 weeks for males and 125 weeks for females. In males and females, respectively, the liver tumour incidences were 1/22 and 2/28 before 99 weeks of age, 5/18 and 2/19 between 100 and 129 weeks and 7/8 and 5/12 from 130 weeks. The cumulative incidences of liver adenomas throughout the study were 0/35 for control and 13/36 for treated males and 0/32 for control and 9/29 for treated females. Fifty male Fischer 344 rats [age unspecified] were placed on a diet containing sodium phenobarbital at 500 mg/kg for 1 week, after which the concentration was increased to 1000 mg/kg of diet and was maintained at this level for 103 weeks. Of the 33 treated rats that lived 80 weeks or more, 11 (33%) developed small foci of nodular hyperplasia; none developed in the controls. Only one treated animal killed at 102 weeks had a lesion, which compressed the surrounding liver without local invasion or metastasis [an adenoma by recent criteria] (Butler, 1978). The hepatocellular carcinomas in sodium phenobarbital-treated (2/30) and control rats (2/30) were all negative for the enzyme (Ward, 1983). Groups of 20 male Fischer 344/DuCrj rats [age unspecified] were fed diets con taining sodium phenobarbital at a concentration of 0 (control), 8, 30, 125 or 500 mg/kg for 104 weeks. No treatment-related changes in clinical signs, survival rates, body weight, food consumption or haematological or blood biochemical end-points were observed at any concentration; however, significantly elevated liver weights (relative to body weight) were noted in groups fed 125 and 500 mg/kg of diet (2. Although foci positive for gluta thione S-transferase (placental form) were found in all groups at termination, the numbers per cm2 and areas (mm2 /cm2) in rats fed the two higher concentrations of sodium phenobarbital were significantly higher than control values (average number, > 25 and > 30 versus > 11, p < 0. No hepatocellular adenomas were found, and hepato cellular carcinomas occurred in only one rat each at 8 and 125 mg/kg of diet. At the con centrations given, no changes were observed in any other organ (including thyroid) (Hagiwara et al. Twelve mice of the same sex and age given water alone under identical conditions served as controls. During the observation period of 80 weeks, no increase in the incidence of tumours of the liver (control, 0/56; sodium phenobarbital, 0/60 [males and females combined]), lung (control, 13/56; sodium phenobarbital, 18/60) or any other organ was found in exposed offspring compared with those of controls (Cavaliere et al. The results of the numerous studies of initiation?promotion show that the primary promoting effect of phenobarbital in mice and rats is on the liver and thyroid. In mice, inhibition or enhancement of hepatocarcinogenesis by phenobarbital depends on the strain, sex, age at the start of exposure and type of initiator used (Uchida & Hirono, 1979; Diwan et al. Selected studies of liver and thyroid tumour promotion are summarized below, while studies of initiation?promotion by phenobarbital in the liver of various species are summarized in Table 3. Table 4 lists similar studies on the thyroid, and Table 5 shows those on other organs. Ten mice from each group were killed at 33 weeks of age, and the remaining mice were killed when found moribund or at Table 3. Administration of phenobarbital significantly increased the inci dence (from 30% to 100%, p < 0. Eight groups of 30 male weanling C3H/HeN mice were given either a normal diet or a diet containing 1. Animals given phenobarbital only with both methionine and choline had longer survival than mice receiving no supplementation when analysed on the basis of deaths with tumours (p < 0. Treatment with phenobarbital only resulted in incidences of hepatocellular carcinoma of 79% in animals on the normal diet, 74% in those on choline-supplemented diet, 60% with methionine supplementation and 31% with methionine plus choline supple mentation. Multiple hepatocellular adenomas and carcinomas developed in 77% of mice exposed to phenobarbital alone. Multiple hepatoblastomas also occurred in 11/30 (37%) mice that received pheno barbital only. Thus, in D2B6F1 mice, the development of hepatoblastoma from its precursor cells (adenoma and carcinoma cells) is strongly increased in the presence of a promoting agent (Diwan et al. Twenty-four had type A tumours (simple nodular growth of liver parenchymal cells) and three male mice had type B tumours (areas of papilliform or adenoid growth of tumour cells with a distorted parenchymal structure). None of the mice exposed to saline and phenobarbital or saline alone developed tumours (Uchida & Hirono, 1979). Three animals from each group were killed at 4, 20 and 28 weeks, and six animals from each group were killed at 12, 36 and 44 weeks of age. Half of the remaining animals were killed at 52 weeks and the remainder at 60 weeks of age. Subsequent exposure to phenobarbital suppressed the development of focal hepatic lesions, decreased the number of adenomas (5/mouse at 44 weeks, 6/mouse at 52 weeks and 8/mouse at 60 weeks) and carcinomas (0 at 44 weeks, 0 at 52 weeks and 1/mouse at 60 weeks) and prolonged the latency or significantly slowed the rate at which hepatocellular tumours developed in these mice (Diwan et al. At 5 weeks of age, they received 500 mg/L sodium phenobarbital in the drinking-water until 51 weeks of age, and the experiment was terminated 1 week later. Subsequent treatment with sodium phenobarbital also promoted the development of spontaneous liver tumours. One week later, they were given 500 mg/L sodium phenobarbital in the drinking-water until termination of the study at 50 weeks of age. At 4 weeks of age, they were given 500 mg/L sodium phenobarbital in the drinking-water until 20 or 28 weeks of age. Subsequent administration of sodium phenobarbital increased both the incidence (88% at 20 weeks, p? Subsequent administration of sodium phenobarbital decreased the incidence of hepatocellular carcinomas (0%) and the number of adenomas per mouse (51.

Recent studies indicate that these tests may also be helpful in planning treatment and predicting recurrence in node positive women with small tumors. For the Breast cases, there are 2 data items that record information on Multigene testing. MammaPrint: A genomic test that analyzes the activity of certain genes in early-stage breast cancer. It tests a sample of the tumor (removed during a biopsy or surgery) for a group of 50 genes. The test can help women and their doctors decide if extending hormonal therapy 5 more years (for a total of 10 years of hormonal therapy) would be beneficial. The Breast Cancer Index reports two scores: how likely the cancer is to recur 5 to 10 years after diagnosis and how likely a woman is to benefit from taking hormonal therapy for a total of 10 years. The EndoPredict test provides a risk score that is either low-risk or high-risk of breast cancer recurring as distant metastasis. Knowing if the cancer has a high or low risk of recurrence can help women and their doctors decide if chemotherapy or other treatments to reduce risk after surgery are needed.
