ABSTRACT
This article reviews the available data regarding the activity of second-line chemotherapy following 5-fluorouracil (5-FU), irinotecan (CPT-11) or oxaliplatin (OXA) alone or in combination. Studies undertaken in this setting, published both as full papers and in abstract form, were critically analyzed. The main conclusion is that clinical research for second and subsequent lines of treatment in advanced colon cancer (ACC) clearly needs to be optimized. A large number of small, non-randomized phase II trials have been reported without definitive conclusions. Efficient conduct of a limited number of high-quality randomized phase II trials with validation of promising regimens via phase III studies seems a preferable approach. This would not only accelerate the evaluation of new therapeutic options, but also, and more importantly, limit the number of patients receiving suboptimal treatments. The responsibility of this indispensable and urgent task lies with all researchers in this field and their partners in the pharmaceutical industry. One means to implement this approach is through strict selection of studies to be both presented and published, encouraging the spread of information provided by statistically well-designed and well-conducted trials that will eventually lead to the definition of the best standard of care for ACC patients. The conduct of repetitive phase II trials that test minor variations in dose and schedule, while commonplace, does little to advance the field.
