Psychosocial factors in lung cancer: Quality of life, economic impact, and survivorship implications

Lung cancer is the leading cause of cancer mortality in men and women. Lung cancer accounts for approximately 30% of all cancer deaths in the United States. In addition, it is the most often diagnosed cancer in men, and the second most often diagnosed cancer in women. Five-year survival rates in lung cancer remain very low, around 15%. Approximately 45% of patients present with stage III disease. The majority of these patients are considered non-resectable, leading to the poor survival statistics seen in this disease. Unfortunately, survival rates have not improved in the past 30 years despite much research in diagnostics and therapeutics. Patients with advanced disease often experience multiple symptoms, including fatigue, pain, dyspnea, cough, hemoptysis, and anorexia. This paper will review the enormous toll that lung cancer takes on society, as well as individuals and families affected. In addition, we will examine psychosocial factors pertinent to lung cancer. Specifically, the article briefly discusses treatment approaches to lung cancer, as they relate to quality of life (QOL). QOL as a construct within lung cancer is then reviewed. Comment is made on the evaluation and prognostic importance of QOL. Next, economic and survivorship aspects of lung cancer are discussed. Finally, a summary of relevant psychosocial interventions for patients diagnosed with lung cancer is given.
