Typical Pulmonary Carcinoid Tumours and the Relevance of Ki-67 Index: A Tertiary Centre Experience in South Australia

Abstract

Pulmonary carcinoid tumours are a rare type of neuroendocrine primary lung malignancy. The WHO classifies carcinoids as typical (TC) and Atypical Carcinoid (AC) based on mitotic rate and necrosis on histology [1,2]. It is widely accepted that TC has a better overall prognosis than AC. A higher stage (the presence of nodal or metastatic disease) at presentation is correlated with poorer outcomes [3].
