The main objective of this study was to describe selected clinico-pathological characteristics of Oral Squamous Cell Carcinoma (OSCC) in Sri-Lanka.
MATERIALS & METHODS: The study sample comprised of eight hundred and ninety six biopsies diagnosed as OSCC. The clinical and histopathological features were analyzed using the Chi-square test.
Of the 896 biopsies, 801 were primary OSCCs, while 95 were recurrent OSCCs. Majority of the patients (78 %) were in the 5(th) to 7(th) decades of life and showed a male predilection. The buccal mucosa was the commonest site of primary OSCC comprising of 43 % of the sample. Of the primary OSCCs, with known TNM stage, 86 % were in stage 3&4 and majority (59 %) of stage 4 tumours showed tumour at one or more excision margins. Of the recurrent OSCC, 46 % developed their recurrences within one year of the excision of the primary tumour.
In Sri-Lanka, OSCC is a major problem. Only half the patients had completely excised tumours (with clearance of >5 mm at all excision margins) at operation, and recurrences appeared early. This data should be considered in the future management policy of OSCC in Sri-Lanka.
本研究的主要目的是描述斯里兰卡口腔鳞状细胞癌（OSCC）的某些临床病理特征。
研究样本包括896例被诊断为OSCC的活检病例。使用卡方检验分析临床和组织病理学特征。
在896例活检病例中，801例为原发性OSCC，95例为复发性OSCC。大多数患者（78%）年龄在50至70岁之间，且男性居多。颊黏膜是原发性OSCC最常见的部位，占样本的43%。在已知TNM分期的原发性OSCC中，86%处于3期和4期，4期肿瘤的大多数（59%）在一个或多个切除边缘显示有肿瘤。在复发性OSCC中，46%在原发性肿瘤切除后一年内复发。
在斯里兰卡，OSCC是一个主要问题。只有一半的患者在手术时有完全切除的肿瘤（所有切除边缘的切缘>5毫米），且复发出现较早。在斯里兰卡OSCC未来的管理策略中应考虑这些数据。
