Switching to anastrozole versus continued tamoxifen treatment of early breast cancer. Updated results of the Italian tamoxifen anastrozole (ITA) trial.

BACKGROUND: Tamoxifen, for many years the 'gold standard' in the adjuvant setting for the management of endocrine sensitive early breast cancer, is associated with an increased risk of endometrial cancer and other life-threatening events. Moreover, many women relapse during or after tamoxifen therapy due to the development of resistance. This provided the rationale for a switching trial with anastrozole, the updated results of which are reported here. PATIENTS AND METHODS: This trial investigated the efficacy of switching to anastrozole for women already receiving tamoxifen. After 2-3 years of tamoxifen treatment, postmenopausal, node-positive, ER-positive patients were randomized to receive either anastrozole 1 mg/day or to continue tamoxifen, 20 mg/day, giving a total duration of 5-years treatment. The primary end point was disease-free survival and secondary endpoints were event-free survival, overall survival and safety. RESULTS: A total of 448 patients were enrolled. At a median follow-up time of 64 months (range 12-93), 63 events had been reported in the tamoxifen group compared with 39 in the anastrozole group [HR 0.57 (95% CI 0.38-0.85) P = 0.005]. Relapse-free and overall survival were also longer in the anastrozole group [HR 0.56 (95% CI 0.35-0.89) P = 0.01 and 0.56 (95% CI 0.28-1.15) P = 0.1]. However, the latter difference was not statistically significant. Overall more patients in the anastrozole group experienced at least one adverse event (209 versus 151: P = 0.000). However, numbers of patients experiencing serious adverse events were comparable (37 versus 40, respectively: P = 0.7). CONCLUSIONS: Switching to anastrozole after the first 2-3 years of treatment was confirmed to improve event-free and relapse-free survival of postmenopausal, node-positive, ER-positive early breast cancer patients already receiving adjuvant tamoxifen.

Focal segmental glomerulosclerosis and hepatitis C virus: a case report.

Focal segmental glomerulosclerosis (FSGS) is a renal disease characterized by sclerotic segmentary lesions, involving a few glomeruli. Male-female ratio is >1 and, in the majority of cases, the patients are aged between 25 to 35 years. The clinical picture is similar to a nephrotic syndrome with non-selective proteinuria poorly sensitive to steroids and often associated with microhematuria. The etiology is still unknown, even in a prevalence in drug addicts, patients with AIDS and subjects with recurrent urological infections with vesico-ureteral reflux was observed. Recent reports showed that chronic infection Hepatitis C Virus (HCV)-related may be associate with or responsible for onset of some syndrome involving the kidney but not the liver. We report the case of a young woman with HCV-Ab positive chronic hepatitis that, during the disease, showed clinical findings of renal involvement, histologically related to a FSGS. We administered to her alpha-IFN at doses of 3 Mega Units thrice-a-week for six months. Serum HCV-RNA, proteinuria and hematuria disappeared simultaneously after the treatment. We underline that the lack of finding of HCV antigens or HCV-RNA in glomerular lesions (as occurred in our patient) does not rule out the virus role in pathogenesis of immunological nephritis. The recovery of our patient as well as the disappearance of proteinuria and hematuria during IFNalpha treatment may be further evidence that FSGS and chronic hepatitis HCV-related are not associated by chance. Further observations and perfectioning of diagnostic techniques are required to clarify the pathogenetic relationship between HCV and renal immunological syndromes.

Thyroid carcinosarcoma, a rare and aggressive histotype: a case report.

Thyroid carcinosarcoma is a rare and aggressive thyroid tumor. Histological examination of a tumor showed the characteristic of epithelial carcinoma and mesenchymal differentiation. We retrospectively analyzed the course of the patient and reviewed the literature in which only 19 other cases are described. Carcinosarcoma of the thyroid is a very aggressive tumor with a clinical course similar to anaplastic thyroid carcinoma. Survival is very short despite aggressive multimodal treatment.

Extralymphonodal Castleman's disease. A case report.

Castleman's disease is a rare lymph node pathology characterized by angiofollicular hyperplasia. There are two forms of the disease: localized and systemic, with different features, symptoms and prognosis. Three are the histological types of disease: plasma cell, hyaline-vascular and mixed variants. We report the case of a 65-year-old female affected by localized plasma cell variant of Castleman's disease. The singularity of our case lies in its localization on the breast and monoclonal plasma cell proliferation inside the nodule.

Efficacy of different schedules in the management of chronic hepatitis C with interferon-alpha.

The best results in terms of clinical remission in chronic hepatitis C are achieved by interferon (IFN)-alpha treatment. We studied 255 patients affected by chronic hepatitis C infection (HCV) and divided into 3 groups. A different IFN-alpha therapeutic schedule was adopted in each group: A) 3 million units (MU) three times per week for 6 months; B) 3 MU three times per week for 12 months; C) 6 MU three times per week for 6 months. A sustained biohumoural and virological remission was observed in only 14.5% of the patients included in group A, in 21.6% of the patients included in group B and in 8% of the patients included in group C. The adoption of more aggressive therapeutic regimens did not offer an improvement in response or patient compliance. At present, the long term efficacy of treatment may be evaluated on the basis of both biochemical and virological data.

Eosinophilic gastroenteritis.

Eosinophilic gastroenteritis is a rare disease of unknown aetiology characterized by eosinophilic infiltration of the gastrointestinal wall and increased peripheral blood eosinophilia. The frequent finding of concomitant extradigestive involvement calls for differential diagnosis to distinguish some multisystemic pathologies, such as connective tissue disease. We recently treated a young woman affected by eosinophilic infiltration of the small and large intestine which spread to other organs. Tests ruled out allergic or parasitic aetiopathogenesis of the disease. The clinical, biological and evolutive findings suggest that eosinophilic gastroenteritis may evolve into idiopathic hypereosinophilic syndrome.

[Immunologic diseases and hepatitis C virus].

Active chronic hepatitis may be associated with various immunologic diseases. In the Mediterranean area and to a lesser extent elsewhere, hepatitis C virus, has often been detected in patients affected by mixed cryoglobulinemia, membranoproliferative glomerulonephritis, polyarteritis nodosa autoimmune type 2b hepatitis, Hashimoto's disease, Sjögren's syndrome and lichen ruber planus. These findings should not be considered fortuitous due to the elevated prevalence of autoantibodies and immunologic abnormalities observed in hepatitis C patients compared with subjects presenting other liver diseases. The pathogenetic evaluation of the association between these immunologic diseases and chronic hepatitis C has led us to suggest that diverse virus C and host induced factors may play a fundamental role in determining these immunologic diseases.

Lipoprotein(a) in cirrhosis. A new index of liver functions?

Over the last few years, lipoprotein(a) [Lp(a)] levels have been investigated because clinical studies have related it to increased cardiovascular and cerebrovascular risk. Although it is known that serum Lp(a) concentrations are controlled genetically, little is known about its metabolism. We studied changes in the lipid profile and Lp(a) values in 57 patients (34 males and 23 females) affected by cirrhosis of the liver subdivided into Child's classes in order to assess whether this lipoprotein is sensitive to reduced liver protein synthesis. The patients presented with low total cholesterol, normal HDL-cholesterol (HDL-c), LDL-cholesterol (LDL-c), triglycerides, apoprotein A1 (Apo-A1) and apoprotein B100 (Apo-B100) concentrations, while Lp(a) concentrations seemed elevated. Grouping the patients into Child's classes revealed that all the lipid parameters investigated reduced as the disease progressed. Lp(a) reduced significantly between Child's Classes I and II and seems to be correlated with the severity of cirrhosis and the clinical worsening of the patients' conditions. These findings suggest that Lp(a) is not only an index of atherosclerosis risk, but also plays a role in monitoring liver functions.
