RESUMO

From February 1983 to January 1985, 497 patients with advanced breast cancer were randomly allocated to receive either epirubicin or doxorubicin in the following combination chemotherapy regimen: fluorouracil (5-FU) 500 mg/m2 intravenous (IV) on days 1 and 8; epirubicin or doxorubicin 50 mg/m2 IV on day 1; cyclophosphamide 500 mg/m2 IV on day 1 (FEC or FAC). Cycles were repeated every 21 days until progression or to cumulative doses of 700 mg/m2 for epirubicin and 550 mg/m2 for doxorubicin. Dose reductions were applied according to the standard criteria. Activity was evaluated in 443 patients (222 in the FEC arm and 221 in the FAC arm). The two experimental groups were comparable in age, performance status, menopausal status, histology, previous treatments, and site of the disease. The overall response rate (complete response and partial response [CR + PR]) was not significantly different: 53.6% for FEC and 56.5% for FAC. The median time to progression was 273 days for FEC and 314 days for FAC; the median survival time was 591 and 613 days, respectively. Leukopenia, anemia, nausea, and vomiting were significantly lower in patients treated with FEC. As for cardiotoxicity, four cases of congestive heart failure (CHF) were recorded among patients treated with FAC while only one was observed in the FEC group. These results indicate that epirubicin in a combination chemotherapy regimen is as active as doxorubicin and is significantly less toxic.

RESUMO

Experimental models have demonstrated the Adriamycin (doxorubicin; Adria Laboratories, Columbus, OH)-potentiating activity of lonidamine. Phase II clinical trials on advanced breast cancer have shown that this drug induced a 16% objective response rate. Present multicentric randomized trial was conducted to verify whether lonidamine can potentiate the antineoplastic effects of conventional fluorouacil, Adriamycin, cyclophosphamide (FAC) chemotherapy in advanced breast cancer. From January 1987 to December 1989, 265 patients were enrolled in this study, and 231 are evaluable for response. After stratification according to institution and ECOG performance status (PS), the patients were randomly allocated to receive either standard FAC therapy (group A) or FAC plus lonidamine (600 mg orally daily three times a day) (group B). After three FAC courses, the patients with no progressive disease were further randomized to either receive continuous treatment up to the time of tumor progression (maximum: 10 courses) or to discontinue therapy when a response "plateau" was reached. In this latter group, the same therapy was restarted at relapse or disease progression. Objective response (complete response plus partial response) was significantly higher in group B (66.3%) compared to group A (42.3%). The actuarial median times to disease progression was also significantly longer (P less than 0.0001) in group B (median 9 months) than in group A (median 6 months). Other than myalgia and gastric pain, no increased toxicity was observed in the lonidamine. The analysis of second randomization are yet available because of the longer follow-up time required. Present findings suggest an interesting additive effect of lonidamine when combined with FAC chemotherapy and warrant further investigation in other therapeutic regimens and in other neoplastic diseases.

RESUMO

A 53-year-old woman experienced rapidly progressing liver failure four years after a quadrantectomy for a breast carcinoma. She had received adjuvant chemotherapy and radiotherapy, and second-line chemotherapy for bone metastasis one year earlier. The hepatic failure manifested with ascites, jaundice, elevation of serum bilirubin and hepatic enzyme levels and hypoalbuminemia. Imaging studies showed an enlarged liver without metastatic lesions. The patient died of hepatic decompensation within two weeks. Liver examination at autopsy revealed massive neoplastic infiltration consistent with a primary breast carcinoma. It is important to realize that this unusual pattern of liver metastasis cannot be demonstrated even with the most advanced techniques of instrumental diagnosis (CT scan, ultrasonography and magnetic resonance imaging), and should be taken into account in the differential diagnosis of rapidly progressing liver failure.

RESUMO

In the present report, we retrospectively analyzed the impact of the timing of surgery during menstrual cycle on disease-free and overall survival of 248 premenopausal patients with stage I/II breast cancer who underwent surgery followed by anthracycline-containing adjuvant chemotherapy. With a median follow-up of 5 years, no statistically significant differences were observed in disease-free or overall survival between women operated upon during the follicular (days 0-14) and the luteal (days 15-32) phase of the menstrual cycle. The impact on disease-free and overall survival of lymph-node status, tumor size and hormone receptor expression, but not of the phase of the menstrual cycle at the time of surgery, was confirmed by univariate and multivariate analysis. However, when combined with hormone receptor status, the phase of the menstrual cycle at the time of surgery proved useful to better define the prognosis of primary breast cancer patients, with significantly longer disease-free and overall survival for patients operated upon during the follicular phase and with positive hormone receptors.
