The eligibility of advanced non-small-cell lung cancer patients for targeted therapy clinical trials.

Background: The selection criteria for phase III trials are often stringent. We aimed to determine how many advanced non-small-cell lung cancer (NSCLC) patients would have been eligible for phase III targeted therapy trials and the proportion receiving anticancer treatment.
Patients and Methods: From March 2007 to May 2008, all advanced NSCLC patients presented at our lung cancer multidisciplinary team meeting were included to assess eligibility for the targeted therapy trials: ECOG-4599, AVAiL, FLEX, TALENT, INTACT-1, INTACT-2, ESCAPE, NEXUS and MONET1. Medical records were examined to determine treatment utilisation and overall survival.
Results: A total of 62 patients were registered: 63% male; median age 71 years; 61% stage IIIB disease. Percentages that met criteria were: ECOG-4599 31%, AVAiL 24%, FLEX 69%, TALENT 27%, INTACT-1 50%, INTACT-2 42%, ESCAPE 39%, NEXUS 63% and MONET1 34%. Common reasons for ineligibility were insufficient life expectancy, poor performance status, abnormal bloods, proteinuria and associated cancer problems. Systemic therapies were received by 66% of patients and median survival was 10.3 months.
Conclusion: Only 24%-69% were eligible for targeted therapy trials but 66% received anticancer treatment. Clinical trials in patients with advanced NSCLC need to be more representative of the majority of patients.
