[Bronchial carcinoids. Our experience with 35 cases].

BACKGROUND

The aim of this study was to review personal experience regarding bronchial carcinoids.

METHODS

This study investigated retrospectively 35 patients with bronchial carcinoids treated in our institution (Unit of General and Thoracic Surgery, University of Bologna) in 20 years (from 1978 to 1997).

RESULTS

The m/f rate was 0.6, the average age 42.5 years and the smokers' percentage 42.8. The patients were symptomatic in 88.6% of cases. The carcinoid was located in the right lung in 17 patients (48.5%) and central in 29 patients (82.8%). Surgical treatment included pneumonectomy (6), lobectomy (17), bilobectomy (3), sleeve lobectomy (2), sleeve bilobectomy (1), sleeve resection of main bronchus (1), bronchotomy and tumorectomy (3) and wedge parenchymal resection (2). Thirty patients (85.7%) presented a typical carcinoid and five (14.3%) atypical carcinoid. Peribronchial and/or hilar lymphonodal metastases were present at surgery in 2 cases (5.7%), both centrally located and atypical. The typical carcinoids showed a real 5 years survival rate of 95.8% (with only one death, not related to the neoplasm), while that of the atypical carcinoids was 80% (one patient died of multiple metastases).

CONCLUSIONS

The conclusions is drawn that although the carcinoid tumours are a distinct group of neuroendocrine lung neoplasms with a good prognosis in the majority of the cases, lobectomy and sleeve lobectomy are still the standard resection procedure for the majority of carcinoids. For atypical carcinoids lobectomies are the minimal oncologic surgical treatment.
