F commencement of your remedy. Assessments have been performed each and every four weeks for the initial 4 months then every eight weeks until disease progression. All adverse events were reported and graded in accordance with the National Cancer Institute Popular Toxicity Criteria (version 3.0) (12). Information have been also collected when icotinib therapy was interrupted or withdrawn on account of adverse events. Changes in the PS scores throughout the course in the therapy were compared with all the baseline score. Routine clinical and laboratory assessments were performed at least every four weeks. Statistical analyses. The key endpoint was to evaluate the progressionfree survival (PFS). PFS was defined because the interval between the start out of the remedy plus the date of the initial observation of illness progression or death from any trigger.1007882-58-7 Purity Secondary endpoints have been the general survival and response price. Overall survival (OS) was assessed from theTable I. Patient qualities.

Results Patient qualities. A total of 510 individuals with NSCLC had been screened involving May possibly 1, 2011 and October 31, 2012. Amongst them, 174 lung adenocarcinoma patients have been treated with icotinib, and 42 individuals with poor PS entered this study (Table I).
