Stiborova M, Borek-Dohalska L, Hodek P, Mraz J, Frei E. New selective and terazosin. Dr. Buzdar: I showed you the 49 deaths due to cardiac events. Nonfatal cardiac events are not statistically significantly different between the two groups. They are slightly higher in the anastrozole arm. Dr. Stephen Johnston: I think a lot of this cardiac difference is about cholesterol, and here the favorable cardiovascular effects of tamoxifen have to be borne in mind rather than any differences between aromatase inhibitors as to what the drug does to absolute cholesterol values. Dr. Kathleen Pritchard: Yes, and the place to see that is in the MA-17 study, where there was a placebo control. There was virtually no difference in cardiac events. Dr. Johnston: Given the absolute HRs of around a 40% improvement for the three trials examining a switch strategy, and up to a 50% improvement in risk reduction for extended adjuvant therapy, I'm more convinced for a switch strategy than an upfront strategy. I know the arguments are being mounted to say we save every recurrence with an upfront strategy, but the contrary argument is very potent on the basis of adverse events. I'm more in the camp represented by Kent Osborne, thinking that there may be a whole group of patients who do better by having tamoxifen and then switching. Dr. Buzdar: I think that is an interesting question, but we have no data to support that, right? Dr. Eric Winer: In the IES, there are more myocardial infarctions; in the BIG 1-98 trial, there is an almost statistically significant increase in non breast cancer deaths; and in the ATAC trial, there is a numerical increase in non breast cancer deaths. I don't think that will be a huge issue for a woman with multiple positive lymph nodes, but as we put women with a T1bN0 lesion who are older and at risk for an MI on aromatase inhibitors, I worry that the risk benefit ratio may be different than what we expect. Dr. Buzdar: We need to keep in mind that when you are following an aging population with a median age of 64 years, and you are looking at outcomes at 6 years, when they are almost close to 70 years old, if you are keeping them free of recurrence, you are not making them immortal. They are going to die from other competing causes. Dr. Johnston: Tmoxifen may help by addressing non breast cancer mortality. Dr. Buzdar: The total years lost of life is far more if you recur early, compared with recurrence 5 or 10 years later in a smaller group of patients. Some of these models don't take this into account, whereas it is included in the Cuzick model. It is a dramatic difference regarding when you start with what therapy. Dr. Steven Come: That's only cancer-specific loss of life. If there is increased loss from noncancer deaths linked to the therapies that would compensate, wouldn't it? Dr. James Ingle: If you look at ATAC, there are more adverse events in that first 2.5 years also, so you have decreased recurrences. What is important may vary between individuals. I think we have to have a way to communicate properly what the reality is, as best we know it. That is where Jack Cuzick's person-years of life lost is valuable; you can say over time what the results of the different models are. Dr. Mitch Dowsett: In ATAC, when you measure PR and PR + , tamoxifen and the combination perform very similarly, which is what you'd expect. The point that Dr. Buzdar was also making is that if you look at the survival.

The generic name is anastrozole. But there are two other drugs that are very similar and really can be considered for our purposes today as the same. One is letrozole which goes by the brand name Femara, and the other is the drug Exemestane which goes by the brand name Aromasin. So these drugs appear in all studies that have been done thus far to be a little bit safer than tamoxifen, and arguably a little more effective. Although a degree of their increased effectiveness is certainly open to question. An important caveat is that unlike tamoxifen, these drugs are solely restricted to women who no longer have menstrual periods or functioning ovaries. If you have functioning ovaries, these drugs are not only ineffective, but they might actually be outright harmful. So there's a large randomized trial with which I'm sure you're familiar, it's called ATAC. And in that trial, 9, 000 women were randomly assigned to treatment with either anastrozole and a placebo, or a placebo and tamoxifen, or both active drugs. So three arms, three treatments, two drugs, one drug, or one drug.The combination arm did no better than tamoxiefn alone, and nobody focuses on that anymore, it's been dropped from most of the analyses. But in that trial, which Michael Baum presented at San Antonio originally two years ago, there was a clear advantage for anastrozole over tam9xifen in terms of preventing recurrent breast cancer.What's interesting is that at that time and with every subsequent follow up there is as yet no difference in survival for women who got anastrozole versus tamoxifen, and that probably speaks to several things including the fact that people with hormone responsive breast cancers have tumors that on average grow slower than tumors that are negative, and therefore it's harder to see differences in survival. The second thing though, quite frankly is that the differences in absolute sense between the two arms of the study, anastrozole versus tamoxifen, has if anything diminished slightly over time. But on the other hand, the third hand, safety in some ways clearly favours anastrozole. So that's the background. What did we learn this year at San Antonio? Well, the first thing is there was a very small trial of neoadjuvant anastrozole versus tamoxifen, presented by Ian Smith. It's called the IMPACT trial, I think it's abstract number one. And quite simply, in this trial they were able to demonstrate in a sense the same thing that the ATAC trial showed, which was a modest advantage for anastrozole over tamoxifen. They focused on HER-2 testing within this, and high.

NSABP-B-35 is the next protocol in a generation of NSABP DCIS trials: B17 compared radiotherapy to no treatment, B-24 added tamoxifen to lumpectomy and radiotherapy, and B-35, which opened in January 2003, compares anastrozole to tamoxifen for five years. We're hoping that anastrozole will be superior to tamoxifen, as it was in the ATAC trial; however, that trial was powered to detect small differences in efficacy. We debated considerably whether ER positivity should be required for eligibility in B-35. Dr Craig Allred reanalyzed data from NSABP-B-24 and demonstrated benefit from tamoxifen only in those patients with ER-positive DCIS. Ultimately, we decided to limit eligibility for B-35 to patients with ERpositive DCIS. Only a small subset of women with DCIS -- approximately 20 percent -- is ER-negative. At the current time, I believe it is overly restrictive and authoritarian to dictate that the community standards require estrogen receptor assay prior to treating DCIS. Adjuvant therapy with tamoxifen for 5 years has become the standard treatment for postmenopausal women with hormone receptor positive breast cancer. There is a significant improvement in survival for those with and without lymph node involvement. Additional benefits include a lower recurrence rate in the conserved breast and ultram. Sensitivity analysis Probabilistic cost-effectiveness results are obtained using Monte Carlo simulation based on 1000 simulations. Costs in the model are incorporated using a gamma distribution, whereas utility values and transition probabilities are incorporated using beta distributions. These are commonly used distributions for these variables and are considered to be appropriate. Results The main results taken from the submission are given in Table 25. Sensitivity analysis Variations in the discount rates for costs and benefits separately have little impact on the cost per QALY. No sensitivity analysis was undertaken on the time frame of the analysis or the transition data within the model. The results of PSA suggest that exemestane is generally more costly and more effective than tamoxifen. In most cases, the incremental cost per QALY gained is lower than the 20, 000 level. The proportion of cases where exemestane would be considered cost-effective at this threshold based on 1000 simulations ; is given in Table 26. Discussion The basic model structure provides a reasonable representation of the treatment pathways for breast cancer. In general, the assumptions used within the model are reasonable. However, the utility value for no recurrence is 0.999, which is considered to be very high and will overestimate the benefits from avoiding recurrences. In addition, the methodology used for modelling osteoporotic fractures may underestimate the potential risk of fractures in the exemestane arm.

To look into this potential problem further, researchers studied 12 women who were taking tamoxifen. 9 Cir. 2003 ; , cert. denied, 543 U.S. 939 2004 . The court also noted that, by licensing Barr to distribute a competing tamoxifen product at a reduced price, the settlement introduced competition that would not have existed had AstraZeneca prevailed on appeal. See id. at 57a-58a. 3 The dissenting judge argued that the validity of drug patent settlements should turn on their "reasonableness" in view of "the strength of the patent" at the time of the settlement, the amount of the payment to the generic challenger, the amount the generic challenger would have earned during the HatchWaxman exclusivity period and any ancillary anticompetitive effects of the agreement. Id. at 126a. REASONS FOR DENYING THE PETITION The petition advances no reason that warrants review of the decision below. There is no conflict in the courts of appeals, and the Second Circuit properly applied this Court's precedents in rejecting petitioners' novel antitrust claims. In addition, there are several reasons why this case, with its factual background that is unlikely ever to recur, is a poor vehicle for considering the standards for pleading that a drug patent settlement violated the Sherman Act. I. THERE IS NO CONFLICT IN THE COURTS OF APPEALS There is no conflict in the decisions of the circuit courts that have assessed antitrust challenges to agreements arising from drug patent litigation under the Hatch-Waxman Act. None of the three circuits that petitioners assert are in conflict.

Conclusions: Upon review of the literature, 3 case reports have documented CD in patients with autoimmune thyroid disease due apparent resistance to LT4. Our case is unique in that CD was diagnosed not only in the hypothyroid patient requiring higher than expected dose of LT4 but also in the work-up of chronic fatigue. Though fatigue is a non-specific complaint, the threshold to screen for other autoimmune disorders such as CD should be lower given the higher prevalence of CD in autoimmune thyroid patients. Abstract #398 METHOTREXATE TREATMENT IN RIEDEL THYROIDITIS: A CASE REPORT AND REVIEW Brian Ellis Michael, MD, FACE, and Lewis E Braverman, MD Objective: To report the successful use of methotrexate in a patient with RT who did not respond to steroid and tamoxifen therapy. Case Presentation: A 38 year old black female presented with acute dyspnea and painful thyroidal swelling in June 2003. She underwent debulking surgery at another institution and sustained damage to the right recurrent laryngeal nerve and hypoparathyroidism. Pathology confirmed a diagnosos of Riedel thyroiditis. Pain and airway symptoms persisted despite institution of thyroid replacement and initiation of corticosteroid therapy. The patient deveoloped a right sided Horner syndrome and Taoxifen therapy was added. Serial CT and ultrasound demonstrated further enlargement of thyroid remnant despite steroid and tamoxifen treatment and a permanent tracheostomy was placed with additional surgical complications. Postoperatively the patent experienced worsening of her Horner syndrome as well as additional respiratory embarassment. Therapy with Methotrexate was added to the treatment regimen after tracheostomy did not fully relieve symptoms. Follow up CT, and ultrasound showed regression of thyroidal enlargement. Symptomatic improvement and resolution of Horner syndrome followed institution of Methotrexate. Discussion: Riedel thyroiditis is a rare disorder that has no consistently satisfactory treatment. Standard therapy after diagnosis is generally high dose corticosteroids and treatment of hypothyroidism. Several case reports exist of successful treatment of RT with the drug tamoxifen. This response is thought to be due to the drug's induction of transforming growth factor beta and is not thought to be due to any effect on estrogen receptors. No studies comparing various treatment modalities appear to exist due to the absence of any large published series of patients affected with this disorder. We describe a particularly aggresive case of RT that was unresponsive to surgical decompression, tracheostomy, corticosteroids and the addition of tamoxifen. The affected individual had severe morbidity associated with attempts at surgical treatment of her disease. She developed progressive airway obstruction and extrathyroidal complications of hypoparathyroidism and a unilateral Horner syndrome despite standard treatment. When the antineoplastic agent Methotrexate was added to her treatment regimen, her Horner syndrome resolved, airway symptoms improved, and imaging studies demonstrated regression Conclusions: Severe cases of Riedel's thyroiditis can cause significant morbidity and potential mortality from thyroidal and extrathyroidal manifestations of the disease. When an affected individual fails to respond to standard treatment measures of surgery, corticosteroids, and tamoxifen, little published data exists to guide additional treatment efforts. Adding the anti-neoplastic agent methotrexate in such a situation may offer significant amelioration of disease progression in a non-responsive patient. Abstract #365 FNAC OF THYROID NODULE: DIAGNOSTIC ACCURACY AND PITFALLS Saeed Ahmed Mahar, MD, FCPS, Akhtar Husain, FRCPath, and Najmul Islam, FRCP Objective: To evaluate the utility of FNAC in patients with Thyroid Nodule. Methods: Records of all patients treated surgically for thyroid nodule s ; at Aga Khan University Hospital from Jan 2000 to Dec 2004 were reviewed. The patients who had pre operative FNAC as first line of the evaluation and the final post operative histopathology report available were included in the study. Results 125 patients 90 female 35 male ; had thyroid surgery. The cytological diagnosis was made according to following categories: Benign, Follicular lesion, Malignant and Inadequate sampling. Among 63 "Benign cases", 57 were benign and 6 turned out to be malignant. Among 44 cases from "Follicular group", 31 were benign and 13 were malignant. Out of 15 patients from "Malignant" group, 14 were malignant and 1 was benign. Among three patients from the "Inadequate sampling group", 2 turned out to be benign and one was malignant. The overall results showed a sensitivity of 98%, specificity of 70%, and positive predictive value of 91%, negative predictive value of 93% and diagnostic accuracy of 91%. Discussion: The aim of this study was to evaluate the diagnostic accuracy in 125 patients with thyroid nodules submitted to FNAC and afterwards to surgery.The false and temazepam.
