Carcinoma in situ at the bronchial resection margin: a review

Abstract

Carcinoma in situ at the mucosal bronchial resection margin is a rarely reported event. At present, such histological findings at the resection margins are classified as R1(is), thus representing an incomplete resection. A review of the English literature on the topic was undertaken to try to better define the significance of such findings and to define possible areas of prospective data acquisition to further define the problem and its management.
