Background:We present wedge resection as an alternative procedure for primary pulmonary carcinoma in poor-risk patients.

Patients and Methods:We examined the overall survival of 94 patients who underwent wedge resection for pN0M0 primary pulmonary carcinoma over the last 20 years because of their intolerance of lobectomy.

Results:In the wedge resection group, the postoperative 5-year survival in all causes of death was 59.6%, indicating significantly better prognoses in patients with adenocarcinoma aged less than 75 years old. The 5-year survival in the lobectomy group was 77.5%, while the 5-year survival in terms of primary causes of death in the wedge resection and lobectomy groups was 89.3% and 88.0%, respectively. There was a significant difference between wedge resection and lobectomy in all causes of death, but not between groups in primary causes of death.

Conclusion:Because there were many non-primary deaths in the wedge resection group, care should be taken to follow comorbidities that cause limited lung resection. Survival in the wedge resection group was not inferior to that in the lobectomy group in analyses of the primary causes of death. We suggest that wedge resection should be a favorable procedure for primary pulmonary carcinoma in poor-risk patients to obtain a large enough sample volume of tumor cells.
