Background Pulmonary carcinoids are rare neoplasms, accounting for approximately 1%–2% of all lung malignancies. A retrospective analysis was undertaken of all patients who underwent surgical resection of pulmonary carcinoid tumours across multiple institutions in Melbourne, Australia. Methods From May 2000 through April 2020, 241 patients who underwent surgical resection of pulmonary carcinoid tumours were retrospectively reviewed. Patient demographics, pathologic data, and long-term outcomes were recorded. Results Median age was 57.7 years and the majority of patients were female (58.9% vs. 41.1%). Typical carcinoid was present in 77.1%. Histological subtype was associated with several factors. Atypical carcinoid was more likely to have larger tumour size and nodal involvement. Overall survival for typical carcinoid at 5, 10, and 15 years was 98%, 95%, and 84%, and for atypical carcinoid was 88%, 82%, and 62%, respectively. Histological subtype and age were found to be independent predictors of overall survival, with worse outcomes for atypical and those above 60 years of age. Disease-free survival was related to sublobar resection (p < 0.001, sub-hazard ratio (SHR): 6.89), lymph node involvement (p = 0.022, SHR: 3.18), and atypical histology (p < 0.001, SHR: 9.89). Conclusion Excellent long-term outcomes can be achieved following surgical resection of pulmonary carcinoids. Atypical histology and lymph node involvement are significant prognostic factors, and sublobar resection should not be considered in patients with either of the above features. Typical carcinoid tumour without nodal involvement may be appropriate for sublobar resection. Typical and atypical carcinoid tumours should be considered distinct disease entities, and as such treated accordingly.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
