Abstract

Several authors proposed the stage at diagnosis and some histopathological features as prognostic factors of bronchial carcinoids. However, since large tumour diameters or nodal metastases are frequently associated to aggressive histology, their prognostic role is unclear. To investigate the relationships between the clinicopathological parameters at diagnosis and outcome, 21 patients were analysed. Overall 26% of the radically resected patients recurred. Recurrences and disease-specific mortality were related to atypical histology and, only in cases with typical histology, to the presence of hilar or mediastinal lymph node metastases. These prognostic factors were valuable independently of the size of the primary tumour, that was remarkably homogeneous, always less than 3 cm, thus not predictive of recurrence. Moreover we evaluated the role of somatostatin receptor scintigraphy, a diagnostic tool only preliminary studied in this field. Scintigraphy with111In-octreotide revealed the primary tumours at diagnosis (8/8), the increase in tumour size in two unresected patients, and all the cases of recurrent or metastatic disease (5/11), sometimes before the appearance of symptoms. These results suggest the usefulness of histology and nodal status as prognostic factors in clinical practice. Somatostatin receptor scintigraphy turns out to be a powerful diagnostic tool, for an accurate staging and an early diagnosis of recurrence in bronchial carcinoids.
