Patient-reported Physical Function Is Associated With Survival After Lung Resection for Non-Small Cell Lung Cancer.

ABSTRACT

BACKGROUND: We investigated the association between preoperative quality of life and long-term survival in patients undergoing surgical resection for non-small cell lung cancer. METHODS: Retrospective analysis was conducted on 388 consecutive patients who completed the quality of life assessment through the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C30 and lung cancer specific module (LC13), before anatomic lung resection for non-small cell lung cancer (2014-2018). Survival distribution was estimated by the Kaplan-Meier method. Cox proportional hazards regression and competing risk regression analyses were used to assess the independent association of preoperative patient-reported outcomes with overall and cancer-specific survival. RESULTS: Higher score in patient-reported physical functioning was significantly associated with longer overall survival. Factors significantly associated with poorer overall survival remained older age (P = .005), low body mass index (P = .007), male sex (P < .001), and nodal involvement (P = .007). Competing regression analysis found that worse baseline lung cancer-specific dyspnea (P = .03), low body mass index (P = .01), worse performance status (P = .03), and lymph node involvement (P = .01) were significantly associated with poorer cancer-specific survival. CONCLUSIONS: Higher patient-reported physical function score was associated with longer overall survival after resection. Our study highlights the significance of routinely collecting quality of life data to aid preoperative decision making in non-small cell lung cancer.
