Abstract
The clinical outcome of patients with OSCC is assessed based on TNM system and currently it is the most reliable indicator on which therapeutic decisions are made. The patients with advanced disease are managed with combined treatment modalities. The aim of this retrospective study was to identify the factors which influence survival of patients with OSCC in Sri Lanka. Four hundred and thirty patients who have been managed surgically using either (1) local excision, (2) local excision+supraomohyoid neck dissection, (3) local excision+modified radical neck dissection, (4) local excision+radical neck dissection, (5) local excision+contra-lateral neck dissection depending on TNM stage, with or without post-operative radiotherapy. Patients with incompletely excised tumours showed statistically significant poor survival which improved with radiotherapy (stage II P=0.002, stage III P=0.017). With reference to TNM stage IV tumours, the patients who had received surgical option 4, showed poor survival compared to surgical options 2, 3, and 5 (P=0.001). However, within the group of patients who had received surgical option 4, those who had nodal metastasis showed poorer survival compared to patients without nodal metastasis. In addition...Continue Reading
