Purpose: This study aimed to assess the 5-year survival, quality of life for cancer- and lung-specific symptoms, and to identify predictive factors of quality of life during a 12-month period after video-assisted thoracic surgery (VATS) for early-stage lung adenocarcinoma.
Methods: A convenience sample of 53 patients who had undergone VATS for lung cancer was used for this longitudinal, prospective study. All participants provided responses to the cancer-specific quality-of-life European Organization for Research and Treatment of Cancer questionnaire as well as a questionnaire for lung cancer-specific symptoms using structured interviews at baseline (T0) and 3-, 6-, 9-, and 12-months post-surgery (T1, T2, T3, and T4, respectively). Generalized estimating equation models were used to investigate whether quality of life scores improved from baseline measures and to determine characteristics associated with changes in scores for quality-of-life post-surgery.
Results: The mean age of participants was 58.5 years (SD = 8.76), and most were female (64.2%). Participants received either a wedge or sublobular lobectomy (47.2%) or a lobectomy (52.8%). The size of the primary tumour for most participants was <2 cm (78.7%). The five-year survival rate was 90%. Lung-specific symptoms of insomnia were worse at T1 compared with baseline. Significant improvements in scores for function and cancer symptoms were seen at T4 compared with scores at T0. Age, marital status, smoking, alcohol consumption, and a history of previous cancer were significantly associated with quality of life.
Conclusions: Surgical resection with VATS resulted in good 5-year survival rates and long-term improvements in quality of life. Our findings suggest VATS for patients with early-stage lung adenocarcinoma should be considered as a means of improving long-term survival and quality of life.
