Prognostic factors in node positive primary breast cancer patients treated with adjuvant CMF.

The influence of various patient and disease-related parameters on survival (S) and disease-free survival (DFS) in 217 node positive primary breast cancer patients treated with surgery followed by adjuvant i.v. cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) was evaluated by univariate and multivariate analyses. Five year actuarial S and DFS were 73.3% and 54.8%, respectively. Univariate analysis revealed that patient age, number of involved axillary nodes and ER status had a significant impact on both S and DFS. PgR positive tumors had improved DFS but no S difference was observed. Menopausal status predicted S but not DFS. Primary tumor size and CMF-induced amenorrhea did not predict disease outcome. Multivariate analysis demonstrated that only degree of nodal involvement and PgR status had independent significant impact on prognosis. Both S and DFS are significantly influenced by the number of involved nodes, whereas improved DFS but not S was evident in patients with PgR positive tumors.

Modification of ultrasonographically measured endometrial thickness after discontinuation of adjuvant therapy with tamoxifen in postmenopausal breast cancer patients.

INTRODUCTION: The aim of this study was to evaluate endometrial changes after five years of tamoxifen treatment by measuring endometrial thickness with transvaginal ultrasonography. MATERIALS AND METHODS: Fifty-five asymptomatic postmenopausal women who had assumed tamoxifen, 20 mg daily, for five years were controlled six months after discontinuation of the therapy. Of these 42 were followed-up at 12 months. Statistical analysis was performed using the analysis of variance for repeated measures and the Anova test; p < 0.05 was considered statistically significant. RESULTS: We found a significant reduction in endometrial thickness at six months (p = 0.0046) and at 12 months (p = 0.0003) but not between six and 12 months (p = 0.06). CONCLUSION: A statistically significant reduction in endometrial thickness after discontinuation of tamoxifen therapy was found. This can probably be attributed to the cessation of the estrogenic side-effects of tamoxifen therapy.

Transvaginal ultrasonography and hysterosonography to monitor endometrial effects in tamoxifen-treated patients.

PURPOSE OF INVESTIGATION: Our purpose was to evaluate if, during tamoxifen treatment, hysterosonography may increase diagnostic accuracy when compared with transvaginal ultrasonography and to identify, when and in how many cases, further biopsies may be avoided. METHODS: We performed transvaginal utrasound in 310 asymptomatic women under tamoxifen treatment, using 8 mm endometrial thickness as the cut-off. One hundred and seven patients with an endometrium thicker than 8 mm were enrolled for hysterosonography. Parameters to be evaluated by transvaginal ultrasound and hysterosonography were thickness and structural features of the endometrium. It was possible to compare ultrasound examinations with histopathological findings obtained by biopsy in 83 patients. RESULTS: Globally only ten patients from the study cohort had true endometrial pathology. Based on structural features of the endometrium, we found a global accuracy of 95.6%, with 2.8% false negatives and 4.1% false positives. CONCLUSION: Hysterosonography can increase diagnostic accuracy during tamoxifen treatment and may allow further invasive investigations to be avoided in patients with suggestive hysterosonographic features.

Survival of patients with relapsing breast cancer: analysis of 302 patients.

This retrospective study analyzes overall survival and relapse-free survival after mastectomy and survival after recurrence of 302 patients with metastatic breast cancer. In the whole group the median survival after mastectomy is 99 months: 5-year survival rate is 68.4% and 10-year survival rate is 38.5%. The median survival from relapse was 36 months: 5-year and 10-year survival rates were respectively 26.8 and 18.9%. Various subsets of patients divided according to several prognostic factors have been analyzed.

Phase II study of cisplatin, gemcitabine and 5-fluorouracil in advanced pancreatic cancer.

BACKGROUND: The aim of this study was to determine the activity of the combination of cisplatin, gemcitabine and 5-fluorouracil (5-FU) as therapy for metastatic or locally advanced inoperable pancreatic adenocarcinoma. PATIENTS AND METHODS: Patients with histologically proven advanced or metastatic pancreatic adenocarcinoma received first-line chemotherapy comprising cisplatin (20 mg/m2 on days 1, 8, 15, 22, 29 and 36), gemcitabine (1000 mg/m2 on days 1, 8, 29 and 36) and 5-FU (200 mg/m2 as continuous infusion on days 1-42) every 56 days. RESULTS: A total of 34 patients were studied. Eighty courses were administered (median two courses per patient). Among 32 patients evaluable for response, two patients had a complete response and four a partial response for an overall response rate of 19% (95% confidence interval 7% to 36%). Thirteen patients had stable disease (40%) and 13 progressed. Median progression-free survival was 4.7 months, median survival 9.0 months and 26% of patients achieved 1-year survival. Ten of 25 patients (40%) with pain at presentation had a sustained reduction of analgesic consumption. The principal grade 3/4 toxicities were neutropenia, thrombocytopenia, anaemia and mucositis, occurring in 24%, 21%, 9% and 3% of patients. CONCLUSION: This schedule seems well tolerated and active in pancreatic cancer and worthwhile of further evaluation.
