Quality of life after lung cancer surgery: a review.

The long-term goals of lung cancer surgery include cancer control, survival and quality of life (QoL). In a patient population with a high mortality rate, evaluation and preservation of QoL after treatment is imperative. Lung cancer patients already have a significant lower QoL compared to an age-matched healthy population with significant impairment in physical and emotional functioning. Lung cancer surgery causes further deterioration of QoL, especially in the first 3 to 6 months after surgery. While some studies suggest that QOL returns to baseline levels at 6 to 9 months postoperatively, others report that QOL is still significantly impaired at 6 and 12 months after surgery. Age, extent of surgery, preoperative lung function, access technique, and adjuvant treatment may all influence postoperative QoL. This review presents the basic concepts of QoL research, several commonly used QoL measurement instruments, and a summary of the available data on post-lung cancer surgery QoL.
