Efficacy and tolerability of chemotherapy in elderly patients with advanced oesophago-gastric cancer: A pooled analysis of three clinical trials

The aim of this study was to determine the benefits of chemotherapy for oesophago-gastric cancer (OGC) in patients 70 years and above (⩾70) in comparison to younger patients. 1080 patients were enrolled into three randomised controlled trials assessing fluorouracil-based combination chemotherapy. Patients received either a platinum-containing regimen (ECF, MCF), PVI 5-FU (protracted venous infusion of 5-fluorouracil) ± mitomycin C (MMC), or FAMTX. Of the 1080 patients randomised, 257 (23.8%) were aged ⩾70 years. There were no significant differences in the incidence of grades 3/4 toxicity between the two cohorts. Objective and symptomatic response rates, failure-free and overall survival were not significantly different. In a multivariate analysis, independent prognostic factors for survival were performance status and locally advanced disease, not age. Patients ⩾70 years with OGC obtained similar benefits from palliative chemotherapy with respect to symptomatic response, tumour regression and survival, without increased toxicities.
