The incidence of bronchial carcinoma in Sri Lanka is low. The extent to which its pattern varies from that prevailing in western countries is demonstrated by a study of 84 cases diagnosed over a 10-year period. Of the patients examined 45-2 per cent were non-smokers, all 17 women belonging to this category. A negative smoking history, especially in women, was not a useful guide in assessing a suspected lesion. Adenocarcinoma, which is usually peripheral, comprised a high proportion of the tumours (22-6%). The majority of cases (70-3%) had had peripheral tumours which were beyond bronchoscopic visibility. Therefore, bronchoscopy was not as useful a diagnostic procedure as in the West. Digital clubbing was seen in less than half the males, while only two females had this sign.
斯里兰卡支气管癌的发病率较低。一项对10年间确诊的84例病例的研究表明，其发病模式与西方国家流行的模式存在差异。在接受检查的患者中，45.2%为非吸烟者，所有17名女性均属于这一类别。吸烟史阴性，尤其是女性，在评估可疑病变时并非有用的指标。通常位于周边的腺癌在肿瘤中占比很高（22.6%）。大多数病例（70.3%）患有支气管镜无法看到的周边肿瘤。因此，支气管镜检查作为一种诊断程序，不像在西方那样有用。不到一半的男性出现杵状指，而只有两名女性有此体征。
