    ABSTRACT: Background:Subgroup analyses of clinical studies suggest that bevacizumab plus XELOX is effective and tolerable in elderly patients with metastatic colorectal cancer (mCRC). The prospective BECOX study examined the efficacy and safety of bevacizumab plus XELOX, followed by bevacizumab plus capecitabine in elderly patients with mCRC.Methods:Patients aged ⩾70 years with Eastern Cooperative Oncology Group performance status 0 out of 1 and confirmed mCRC were included. Patients received bevacizumab 7.5 mg kg(-1) and oxaliplatin 130 mg m(-2) on day 1, plus capecitabine 1000 mg m(-2) bid orally on days 1-14 every 21 days; oxaliplatin was discontinued after 6 cycles. The primary end point was time to progression (TTP).Results:The intent-to-treat population comprised 68 patients (65% male, median age 76 years). Median TTP was 11.1 months; median overall survival was 20.4 months; overall response rate was 46%. Grade 3 or 4 adverse events included diarrhoea (18%) and asthenia (16%). Grade 3 or 4 adverse events of special interest for bevacizumab included deep-vein thrombosis (6%) and pulmonary embolism (4%).Conclusions:Bevacizumab plus XELOX was effective and well tolerated in elderly patients in the BECOX study. The adverse-event profile was similar to previous reports; no new safety concerns were identified. Fit elderly patients with mCRC should be considered for treatment with bevacizumab plus XELOX.British Journal of Cancer advance online publication, 19 June 2014; doi:10.1038/bjc.2014.346 www.bjcancer.com.

    ABSTRACT: This phase II trial studied the antitumor effect and toxicity of weekly irinotecan (CPT-11, 125 mg/m(2) 60 min iv infusion, weekly for 4 wk plus 2 wk rest) as second-line chemotherapy in patients with advanced colorectal cancer (CRC) resistant or refractory to prior 5-fluorouracil (5-FU) therapy. Sixty-nine patients with adenocarcinoma (57% in the colon and 43% in the rectum) were enrolled. The median number of treatment cycles received per patient was 4 (range, 1-6). Overall response rate was 18% (95% CI, 9-26), with 4 complete responses (6%) and 8 partial responses (12%), and a median duration of response of 8.1 mo (95% CI, 4.2-12.1). Stable disease was observed in 19 patients (28%). The median time to disease progression was 5.2 mo (95% CI, 4.3-6.1), and the median overall survival was 13.3 mo (95% CI, 9.8-16.8 months). The toxicity profile was favorable: grade 3/4 delayed diarrhea was observed in 10 patients (14.5%) in one cycle each, and grade 3/4 neutropenia in 6 patients (8.7%) and 6 cycles (3.3%). No febrile neutropenia or infection was documented. Grade 3/4 nausea and vomiting were reported in 1 (1.4%) and 7 patients (10.1%), respectively. In conclusion, this phase II trial showed a response rate and a toxicity profile of weekly CPT-11 in line with the results of prior phase II studies.
