<p>Objectives. Wedge resection (WR) is often the preferred surgical treatment for poor-risk primary lung cancer patients. However, there is still some debate regarding its indication. The aim of the present study was to investigate the surgical outcomes of WR as a compromise procedure. Methods. The study population consisted of 93 patients with primary lung cancer who underwent WR as a compromise procedure from April 2007 to March 2020. We reviewed the clinical features and outcomes of the treatment. Results. Complete resection was performed in 84 patients (90.3%). When stratified by pathological stage, the 3- and 5-year overall survival rates were 74.7% and 67.3%, respectively, in the stage IA group; 66.3% and 41.4% in the stage IB group; and 48.0% and 24.0% in the stage II group. Sex, histological type, and visceral pleural invasion were recognized as prognostic indicators. However, the prognostic impact of tumor size was not clear. Twenty-nine patients (34.5%) developed recurrence, including distant metastasis in 14 patients and locoregional recurrence in 13 patients (including 8 patients with stump recurrence); both types of recurrence were detected in 2 patients. The morbidity rate was 9.7%; however, there were no serious complications. No significant difference was found in morbidity in comparison to patients who underwent intentional WR. Conclusion. WR can be expected to achieve acceptable surgical outcomes in poor-risk stage I lung cancer patients.</p>
