RESUMO

OBJECTIVES: Favorable phase I results justified this pilot phase II study to assess the efficacy of docetaxel/curcumin in patients with chemotherapy-naive metastatic castration-resistant prostate cancer (CRPC). METHODS: Thirty patients with progressing CRPC and a rising prostate-specific antigen (PSA) received docetaxel/prednisone in standard conditions for 6 cycles in combination with per os curcumin, 6,000 mg/day (day -4 to day +2 of docetaxel). The co-primary endpoint was the overall response rate determined by PSA and target assessments. An ancillary study assessed the seric values of chromogranin A (CgA) and neuron-specific enolase (NSE). RESULTS: Twenty-six patients received the scheduled treatment, 2 progressed and 2 died before the end of treatment. A PSA response was observed in 59% of patients (14% of PSA normalization) and achieved within the first three cycles for 88% of responders. Partial response was reached for 40% of evaluable patients. The regimen was well tolerated, and no adverse event was attributed to curcumin. Twenty patients were 100% curcumin compliant. The PSA level and objective response rate were not correlated with the serum values of CgA and NSE. CONCLUSION: This study produced additional data on curcumin as a treatment for cancer, with a high response rate, good tolerability and patient acceptability, justifying the interest to conduct a randomized trial.

RESUMO

BACKGROUND: Everolimus (Afinitor®) plus exemestane are indicated for hormone receptor-positive, HER2/neu-negative metastatic breast cancer (MBC), in menopausal women without symptomatic visceral disease after recurrence or progression following aromatase inhibitors. But everolimus efficacy as late treatment has not been explored. METHODS: Sixty-three MBC patients progressing under hormonotherapy (HT; n = 30) or after chemotherapy (CT; n = 32) received everolimus plus HT (EHT) and were analyzed for safety, efficacy and overall survival (OS). This cohort was compared with our previous 530 MBC patients stratified by line (PMID 21852136). RESULTS: The median duration of EHT was 27.8 weeks at 5-10 mg/day until clinical progression or toxicity. Median OS was not reached (median follow-up 18 months). Twelve-month survival was 100, 79 and 49% for patients treated with 0 (n = 13), 1-2 (n = 18) and >3 CT (n = 32), respectively. Median time-to-treatment failure was 6.4 months. In 62 EHT patients randomly matched 1:7 with 421 previous patients for age and number of CT, OS improved compared with patients receiving a new CT (p = 0.062). In patients pretreated with <2 CT, EHT gave a better OS than in those with a new CT (p = 0.026). CONCLUSIONS: These results may support the use of EHT whatever the number of previous lines.

RESUMO

This study compares the outcome of 76 patients with N0 breast carcinoma, node-negative at axillary lymph node dissection (pN0) after neoadjuvant chemotherapy (NeoCT), treated with (RLNI+, 39 patients) or without (RLNI-, 37 patients) elective regional lymph node areas irradiation. For RLNI- and RLNI+ groups respectively at 10 years, survival without local-regional recurrence was 95% and 91% (p = .59), survival without distant metastasis was 97% and 78% (p = .018) and overall survival was 96% and 75% (p = .013). Clinical size < 4 cm was a strong pronostic factor.

RESUMO

BACKGROUND: Weight change during chemotherapy is reported to be associated with a worse prognosis in breast cancer patients, both with weight gain and weight loss. However, most studies were conducted prior to the common use of anthracycline-base chemotherapy and on North American populations with a mean BMI classified as overweight. Our study was aimed to evaluate the prognostic value of weight change during anthracycline-based chemotherapy on non metastatic breast cancer (European population) with a long term follow-up. METHODS: Patients included 111 women diagnosed with early stage breast cancer and locally advanced breast cancer who have been treated by anthracycline-based chemotherapy regimen between 1976 and 1989. The relative percent weight variation (WV) between baseline and postchemotherapy treatment was calculated and categorized into either weight change (WV > 5%) or stable (WV < 5%). The median follow-up was 20.4 years [19.4 - 27.6]. Cox proportional hazard models were used to evaluate any potential association of weight change and known prognostic factors with the time to recurrence and overall survival. RESULTS: Baseline BMI was 24.4 kg/m2 [17.1 - 40.5]. During chemotherapy treatment, 31% of patients presented a notable weight variation which was greater than 5% of their initial weight.In multivariate analyses, weight change (> 5%) was positively associated with an increased risk of both recurrence (RR 2.28; 95% CI: 1.29-4.03) and death (RR 2.11; 95% CI: 1.21-3.66). CONCLUSIONS: Our results suggest that weight change during breast-cancer chemotherapy treatment may be related to poorer prognosis with higher recurrence and higher mortality in comparison to women who maintained their weight.

RESUMO

Temozolomide (TMZ) was first known to be useful as a radiosensitiser in both primary brain tumours like glioblastoma multiforme and oligodendroglioma. Later, TMZ proved its efficacy in the treatment of melanoma. Multiple publications have demonstrated the benefit of TMZ in terms of efficacy and tolerance (used as mono-therapy or as adjuvant chemotherapy) compared to the "gold standard" treatment of this kind of tumours. Furthermore, several recent clinical trials have shown the particular importance of TMZ in other types of cancer. This publication deals with the use of TMZ in cancers which are not formal indications for TMZ (excluding glioblastoma multiforme, oligodendroglioma and melanoma). It also includes a necessary review of recent literature about the role of TMZ in the treatment of brain metastases, lymphomas, refractory leukaemia, neuroendocrine tumours, pituitary tumours, Ewing's sarcoma, primitive neuroectodermal tumours, lung cancer and other tumours.

RESUMO

Numerous studies have demonstrated that a significant change in weight during chemotherapy treatment was a factor of poor prognosis in early breast cancer women. However, the causes and mechanisms involved in this phenomenon are not fully known. This review summarizes current knowledge about the causes of energy imbalance during chemotherapy treatment and the mechanisms that have been proposed as responsible for the increased risk of relapse and death in this population. Current preventive strategies focus on physical activity programs but also on the use of metformin during and after chemotherapy.

RESUMO

BACKGROUND: Since the improvement of chemotherapy with safe molecules is needed for a better efficacy without supplementary toxicity, we investigated the feasibility and tolerability of the combination of docetaxel and curcumin, a polyphenolic derivative extracted from Curcuma longa root. RESULTS: Fourteen patients were accrued in this open-label phase I trial. At the last dose level of curcumin, three dose-limiting toxicities were observed and two out of three patients at this dose level refused to continue treatment, leading us to define the maximal tolerated dose of curcumin at 8,000 mg/d. Eight patients out of 14 had measurable lesions according to RECIST criteria, with five PR and three SD. Some improvements as biological and clinical responses were observed in most patients. PATIENTS AND METHODS: Patients with advanced or metastatic breast cancer were eligible. Docetaxel (100 mg/m(2)) was administered as a 1 h i.v. infusion every 3 w on d 1 for six cycles. Curcumin was orally given from 500 mg/d for seven consecutive d by cycle (from d-4 to d+2) and escalated until a dose-limiting toxicity should occur. The primary endpoint of this study was to determine the maximal tolerated dose of the combination of dose-escalating curcumin and standard dose of docetaxel chemotherapy in advanced and metastatic breast cancer patients. Secondary objectives included toxicity, safety, vascular endothelial growth factor and tumor markers measurements and assessment of objective and clinical responses to the combination therapy. CONCLUSION: The recommended dose of curcumin is 6,000 mg/d for seven consecutive d every 3 w in combination with a standard dose of docetaxel. From the encouraging efficacy results, a comparative phase II trial of this regimen plus docetaxel versus docetaxel alone is ongoing in advanced and metastatic breast cancer patients.
