Quality-of-life trials in lung cancer: past achievements and future challenges.
Much work has been done regarding QOL in lung cancer trials. There are now several validated QOL instruments, particularly for patients with lung cancer. Past accomplishments include key trials demonstrating a benefit of chemotherapy or radiation in patients with advanced NSCLC not only regarding traditional endpoints but also by improving palliation and aspects of QOL such as pain and dyspnea. More recently, studies have emerged that incorporate QOL in patients with locally advanced disease. Key challenges relate to the optimal design and successful completion of these QOL studies. Missing data remains a key problem in many QOL studies, particularly in lung cancer trials. Future studies should focus on incorporating QOL into phase III studies with clear hypotheses that can ultimately lead to clinically meaningful interventions.
