Is sublobar resection sufficient for carcinoid tumors?

Area of Science:

• Thoracic oncology
• Surgical oncology
• Epidemiology

Background:

• Current guidelines for lung carcinoid tumor resection are based on non-small cell lung cancers.
• Limited single-institution data necessitates large-scale analysis for carcinoid tumors.

Purpose of the Study:

• To investigate the impact of resection extent on overall survival in lung carcinoid tumors.
• To analyze the Surveillance, Epidemiology, and End Results (SEER) database for population-based insights.

Main Methods:

• Analysis of the SEER database (1973-2006) for patients with lung carcinoid tumors.
• Inclusion of variables: age, race, gender, histology, stage, resection extent, and survival.
• Application of univariate (Kaplan-Meier) and multivariate (Cox regression) analyses, including propensity score-matched analysis for typical carcinoids.

Main Results:

• Extent of resection was not a statistically significant factor for overall or disease-specific survival in multivariate analysis.
• Propensity score-matched analysis confirmed that resection extent does not impact survival for typical carcinoids.
• Gender, race, stage, and histology were significantly associated with survival.

Conclusions:

• Sublobar resection of lung carcinoid tumors is oncologically safe and does not compromise outcomes.
• Lobectomy is not mandatory for typical carcinoid tumors if complete resection and adequate mediastinal staging are performed.
