RESUMO

This study aimed to verify whether the advantage in terms of response rate and survival of dacarbazine plus tamoxifen over dacarbazine alone in metastatic malignant melanoma reported in a previous randomized trial was due to a specific interaction of dacarbazine with tamoxifen. A total of 125 patients with locoregional or disseminated malignant melanoma were randomized to receive dacarbazine (250 mg/m(2) days 1-5 every 3 weeks) plus tamoxifen (arm A) or vindesine (3 mg/m(2) every week for 6 weeks, then every 2 weeks) plus tamoxifen (arm B). Of the 125 randomized patients, 57 and 59 were evaluable in arm A and B, respectively. The complete response rates were the same (2% versus 2%) and the complete plus partial response rates were similar (11% versus 14%) in the two groups. There was no significant difference in survival. Neither response or survival correlated with gender. In conclusion, when combined with tamoxifen, dacarbazine does not have a specific effect on response or survival compared with vindesine. The lower response rate to dacarbazine plus tamoxifen (11%) than that reported in the previous trial (28%) might be explained by actual differences in patient and/or participating centre accrual characteristics in the presence of apparently identical eligibility criteria.

RESUMO

We compared a relatively short regimen of monochemotherapy with epirubicin versus polychemotherapy with CMF (cyclophosphamide, methotrexate, 5-fluorouracil) as adjuvant treatment for stage I and II breast cancer patients. 348 patients with oestrogen receptor negative (ER-) node negative and ER- or ER+ node-positive with <10 nodes were accrued. CMF was given intravenously (i.v.) on days 1 and 8, every 4 weeks, for six courses; epirubicin was given weekly for 4 months. Postmenopausal patients received tamoxifen for 3 years. The primary endpoints were overall survival (OS), relapse-free survival (RFS) and event-free survival (EFS). Outcome evaluation was performed both in eligible patients and in all randomised patients according to the intention-to-treat principle. 8 randomised patients were considered ineligible. At a median follow-up of 8 years, there was no difference in OS (Hazard Ratio (HR)=1.11, 95% Confidence Interval (CI): 0.77-1.61, P=0.58), EFS (HR=1.14, 95% CI: 0.78-1.64, P=0.48), and RFS (HR=1.14, 95% CI: 0.8-1.64, P=0.48) between the two arms for all of the patients. At 8 years, the RFS percentages (+/-Standard Error (S.E.)) were 65.4% (+/-4%) in the CMF arm and 62.7% (+/-4%) in the epirubicin arm; for EFS these were 64.2% (+/-4%) for CMF and 60.8% (+/-4%) for epirubicin, respectively. A significant difference in RFS (P=0.015) was observed in patients with 4-9 positive nodes in favour of the CMF arm. Toxicity in the two arms was superimposable except for more frequent grade 3 alopecia in the epirubicin-treated patients (P=0.001). Overall, at a median follow-up of 8 years, there were no differences between the two arms in terms of OS, EFS and RFS.

RESUMO

BACKGROUND: The conventional treatment of brain metastases not amenable to surgery is most often radiotherapy. Until now, pharmacologic issues related to the blood brain barrier (BBB) prevented a wide evaluation of chemotherapy. The authors previously reported that the combination of cisplatin (P) and etoposide (E) had strikingly high activity in patients with brain metastases from breast carcinoma. The purpose of this study was to assess, in a larger prospective study, the front-line activity of that combination against brain metastases from breast carcinoma (BC), nonsmall cell lung carcinoma (NSCLC), and malignant melanoma (MM) in patients previously untreated with radiotherapy. METHODS: From December 1986 to July 1993, 116 patients received P 100 mg/m2 on Day 1 and E 100 mg/m2 on Days 1, 3, and 5 or on Days 4, 6, and 8 every 3 weeks. An insignificant change in the E schedule using the same dose on a random basis assured the prospective enrollment and the registration of all cases. Six patients were not eligible and three patients were excluded from the analysis because they were lost to follow-up shortly after the date of registration. One-hundred seven patients were considered for analysis. The distribution according to the primary tumor site was BC in 56 patients (52%), NSCLC in 43 (40%), and MM in 8 (8%). The first evaluation of response was performed after two cycles. In cases of no disease progression, chemotherapy was continued to a maximum of six cycles. RESULTS: Among the 56 patients with BC, 7 achieved complete response (CR) (13%), 14 achieved partial response (PR), 12 had no change (NC), 15 had progressive disease (PD), and 8 had insufficient treatment or response was not assessed. The CR plus rate was 38%. Among the 43 patients with NSCLC, 3 achieved CR (7%), 10 achieved PR, 15 had SD, 7 had PD, and 8 had insufficient treatment or response was not assessed. The CR plus PR rate was 30%. None of the eight patients with MM achieved an objective response. The median survival was 31 weeks for patients with BC (range, 0-287), 32 for patients with NSCLC (0-392+), and 17 for patients with MM (2-48). CONCLUSIONS: The combination of P and E is effective for patients with brain metastases from BC and NSCLC. In this study, the response rate was of the same order as that reported for disseminated disease without central nervous system involvement. The survival figures compare favorably with some others reported in the literature for patients given radiotherapy. A randomized study is warranted to compare this chemotherapy followed by radiotherapy with radiotherapy alone for patients with brain metastases from BC or NSCLC not amenable to surgery or radiosurgery.

RESUMO

PURPOSE: To compare, in a double-blind, placebo-controlled, randomized trial, the efficacy of two different doses of the depot formulation of adrenocorticotropic hormone (ACTH) in controlling delayed emesis after cisplatin. PATIENTS AND METHODS: One hundred fifty-two patients were enrolled onto the study. On day 1, all patients received cisplatin (60 to 120 mg/m2) and a combination of dexamethasone 20 mg plus ondansetron or metoclopramide to prevent acute emesis. On day 2 (24 hours after cisplatin administration), patients were randomized to receive placebo, or ACTH 1 mg intramuscularly (I.M.), or ACTH 2 mg I.M. plus one additional dose of 1 mg on day 4. Details of vomiting, nausea, and adverse effects were recorded daily for every 24-hour period from day 2 to day 6. In a subset of patients, serum cortisol levels were measured between 20 and 72 hours after cisplatin administration. RESULTS: One hundred fifty patients were assessable. Over the 5 days of the study, delayed vomiting occurred less frequently in the patients treated with ACTH 2 mg plus 1 mg than in those treated with ACTH 1 mg or placebo (28%, 38%, and 65%, respectively; P = .001). The greatest observed differences were seen on days 2 (24 to 48 hours; P = .01) and 3 (48 to 72 hours; P = .01). On days 4, 5, and 6 (96 to 144 hours), no significant differences were observed among the three arms. The severity of delayed emesis expressed as the mean number of emetic episodes per day was 0.48, 0.70, and 0.80, respectively (P = .002). Patients treated with the higher dose of ACTH had the least nausea on day 3 (P = .02) and day 4 (P = .03). Adrenal cortisol secretion rapidly increased after ACTH injection, but was suppressed for approximately 44 hours in the placebo group. Toxicity was mild and transient in all groups. CONCLUSION: ACTH reduces the incidence and severity of delayed vomiting and nausea after cisplatin. A dose of 2 mg 24 hours after cisplatin is better than one of 1 mg. Whether the activity of ACTH is mediated only by adrenal corticosteroids needs to be verified.
