Background: Chemoradiation improves survival for patients with locally advanced non-small cell lung cancer (NSCLC), but clinical outcomes beyond five years are rarely reported. The aim of the present study was to identify the long-term results of a phase II study of docetaxel and cisplatin with concurrent thoracic radiation.
Methods: We previously reported short-term outcomes from the phase II study, which enrolled 42 patients (aged ≤ 75 years) with unresectable stage III NSCLC. We continued to follow these patients for long-term clinical outcomes.
Results: At a median follow-up for all patients of 6.3 years (range: 5.2-7.1 years), the median survival time was 2.1 years and the actual five-year survival rate was 31%. Among 14 patients who were progression-free longer than two years, three patients died due to bacterial or fungal pneumonia and one died due to gall bladder cancer.
Conclusions: Thirty-one percent of locally advanced patients having NSCLC treated with docetaxel and cisplatin and concurrent thoracic radiation survived beyond five years. Progression-free patients might be cautiously followed up taking precautions against emerging pneumonia.
