RESUMO

BACKGROUND: Evidence on adjuvant chemotherapy in older women with breast cancer is poor. We tested whether weekly docetaxel is more effective than standard chemotherapy. PATIENTS AND METHODS: We carried out a multicenter, randomized phase III study. Women aged 65-79, operated for breast cancer, with average to high risk of recurrence, were allocated 1 : 1 to CMF (cyclophosphamide 600 mg/m², methotrexate 40 mg/m², fluorouracil 600 mg/m², days 1, 8) or docetaxel (35 mg/m(2) days 1, 8, 15) every 4 weeks, for four or six cycles according to hormone receptor status. Primary end point was disease-free survival (DFS). A geriatric assessment was carried out. Quality of life (QoL) was assessed with EORTC C-30 and BR-23 questionnaires. RESULTS: From July 2003 to April 2011, 302 patients were randomized and 299 (152 allocated CMF and 147 docetaxel) were eligible. After 70-month median follow-up, 109 DFS events were observed. Unadjusted hazard ratio (HR) of DFS for docetaxel versus CMF was 1.21 [95% confidence interval (CI) 0.83-1.76, P = 0.32]; DFS estimate at 5 years was 0.69 with CMF and 0.65 with docetaxel. HR of death was 1.34 (95% CI 0.80-2.22, P = 0.26). There was no interaction between treatment arms and geriatric scales measuring patients' ability or comorbidities. Hematological toxicity, mucositis and nausea were worse with CMF; allergy, fatigue, hair loss, onychopathy, dysgeusia, diarrhea, abdominal pain, neuropathy, cardiac and skin toxicity were worse with docetaxel. One death was attributed to CMF and two to docetaxel. Increasing age, impairment in instrumental daily living activities, number of comorbidities and docetaxel treatment were independently associated with severe nonhematological toxicity. QoL was worse with docetaxel for nausea-vomiting, appetite loss, diarrhea, body image, future perspective, treatment side-effects and hair loss items. CONCLUSIONS: Weekly docetaxel is not more effective than standard CMF as adjuvant treatment of older women with breast cancer and worsens QoL and toxicity. CLINICALTRIALSGOV: NCT00331097.

RESUMO

The sequential doxorubicin --> CMF (CMF=cyclophosphamide, methotrexate, fluorouracil) regimen has never been compared to CMF in a randomised trial. The role of adding goserelin and tamoxifen after chemotherapy is unclear. In all, 466 premenopausal node-positive patients were randomised to: (a) CMF x 6 cycles (CMF); (b) doxorubicin x 4 cycles followed by CMF x 6 cycles (A --> CMF); (c) CMF x 6 cycles followed by goserelin plus tamoxifen x 2 years (CMF --> GT); and (d) doxorubicin x 4 cycles followed by CMF x 6 cycles followed by goserelin plus tamoxifen x 2 years (A --> CMF --> GT). The study used a 2 x 2 factorial experimental design to assess: (1) the effect of the chemotherapy regimens (CMF vs A --> CMF or arms a+c vs b+d) and (2) the effect of adding GT after chemotherapy (arms a+b vs c+d). At a median follow-up of 72 months, A --> CMF as compared to CMF significantly improved disease-free survival (DFS) with a multivariate hazard ratio (HR)=0.740 (95% confidence interval (CI): 0.556-0.986; P=0.040) and produced a nonsignificant improvement of overall survival (OS) (HR=0.764; 95% CI: 0.489-1.193). The addition of GT after chemotherapy significantly improved DFS (HR=0.74; 95% CI: 0.555-0.987; P=0.040), with a nonsignificant improvement of OS (HR=0.84; 95% CI: 0.54-1.32). A --> CMF is superior to CMF. Adding GT after chemotherapy is beneficial for premenopausal node-positive patients.

RESUMO

BACKGROUND AND AIM: In vitro, methotrexate (MTX) is the best modulator for bolus 5-fluorouracil (5FU), whereas folinic acid (FA) is the best for continuous infusion. We evaluated the effect of 5FU modulated by both MTX (bolus administration) and FA (continuous infusion) as second-line treatment of patients with metastatic colorectal cancer. PATIENTS AND METHODS: Entry criteria were: at least one 5FU-based chemotherapy regimen as first-line treatment for metastatic disease, or progression within twelve months after 5FU-containing adjuvant therapy. Treatment schedule: MTX 200 mg/m2 i.v. days 1 and 15; 5FU 600 mg/m2 i.v. bolus, days 2 and 16; 5FU 200 mg/m2 i.v. continuous infusion for 21 days, starting on day 29; FA 20 mg/m2 i.v. bolus weekly during the three weeks of 5FU infusion. Cycles were repeated every 56 days. The primary end-point was tumour control rate, including partial responses and stabilizations. RESULTS: 34/35 patients enrolled were evaluable for response. Five (14.7%) had a partial response, 13 (38.2%) disease stabilization, and 16 (47.1%) progressed; tumour control rate was 52.9%. Median TTP was 5.8 months (95% CI 4.03-7.83); 29 patients had died. Median OAS was 15.9 months (95% CI 8.8-21.9). Toxicity was mild. CONCLUSIONS: The regimen constituted by 5FU modulated by MTX (bolus administration) and FA (continuous infusion) is active as second-line treatment of metastatic colorectal cancer.

RESUMO

Aim of the study was to improve cure rate and survival of aggressive non-Hodgkin's lymphoma (NHL) with a tailored program of therapy based on histologic type, prognostic characteristics of patients and response to therapy, and with the use of differentiating or cytostatic agents such as Ara-C at low doses and alphaIFN. Fifty-four consecutive patients with aggressive NHL were treated in the induction phase with 4 sequential courses of a third generation regimen (modified CODBLAM IV), followed in responsive patients by 1 cycle of doxorubicin and cyclophosphamide and 1 cycle of high dose methotrexate with folinic acid rescue (AC-MTX). Patients who achieved partial response (PR) were treated with the combination of CCNU + vinblastine if affected by high grade NHL, or with low dose Ara-C plus alphaIFN if affected by intermediate grade NHL. Patients who obtained complete response (CR) with basal adverse prognostic factors were treated with alphaIFN as maintenance therapy for two years. Radiotherapy and surgery were effected in selected cases. Thirty-four patients (62.9%) achieved CR and 12 patients (22.2%) showed PR after induction therapy. Among the 12 patients who achieved PR, 6 prolonged CRs were obtained in 7 patients treated with Ara-C at low doses plus alphaIFN and 4 CRs were obtained in 5 patients treated with CCNU + vinblastine. After completion of treatment, 44 patients (81.5%) obtained CR, 2 patients (3.7%) showed PR and 8 patients (14.8%) presented progression of disease (PD). Fifteen patients received alphaIFN as maintenance therapy. The overall survival and failure-free survival rates are 53.7% and 50% respectively, with a median follow-up of 82 months: 27 patients remain alive, disease-free without relapses, and can be considered cured. This tailored program of therapy resulted effective and moderately toxic and may improve the outcome in aggressive NHL.

RESUMO

The aim of this study was to test the hypothesis of Goldie and Coldman that the use of non-cross-resistant regimens of chemotherapy could lead to maximal anti-tumour effect. We compared standard CMF (cyclophosphamide, methotrexate, fluorouracil) with alternating CMF/EV (epirubicin, vincristine) in the adjuvant therapy of early breast cancer. Stage II premenopausal node-positive or post-menopausal node-positive oestrogen receptor-negative and stage III breast cancer patients were eligible for the study. From January 1985 to December 1990, 220 patients were randomised (115 to CMF and 105 to CMF/EV). Toxicity was mild; neurotoxicity, vomiting and hair loss were more frequent in the CMF/EV group, while permanent amenorrhoea, diarrhoea, stomach ache and minor infections occurred more often in the CMF arm. At a follow-up of 48 months, 113 patients (51.4%) had had recurrence (62 on CMF and 51 on CMF/EV) and 54 (24.5%) had died (30 on CMF and 24 on CMF/EV). There was no significant difference in disease-free and overall survival between the two arms. After adjusting for menopausal status and stage, the relative risk (RR) of recurrence for CMF/EV patients was 0.93 (95% CL 0.64-1.35), while the RR of death was 0.85 (95% CL 0.49-1.47). In conclusion, the Goldie-Coldman model of alternating therapy is not confirmed in this trial of adjuvant therapy of early breast cancer, although in view of its design a difference of less than 20% in 3 year disease-free survival could not be excluded.

RESUMO

The effects of slow-release nifedipine on blood pressure and cardiac workload have been studied during bicycle exercise testing in a randomized, double blind trial in 20 patients with mild to moderate hypertension. After a fortnight's wash-out, patients were allocated to either slow-release nifedipine (20 mg twice daily) or placebo for a 2-month period. At baseline and at the end of treatment blood pressure and heart rate were measured at rest and during ergometric exercise; cardiac workload was calculated as the product of systolic blood pressure by heart rate. Significant decreases in blood pressure at rest and in cardiac workload on exercise were demonstrated at the end of nifedipine treatment. The reduction of cardiac workload was mainly due to the lower baseline values of resting blood pressure. Heart rate showed a reduction of its increase during ergometric exercise at the end of nifedipine treatment as compared to baseline, likely due to an improvement in stroke volume.
