Prognostic factors on surgically and non-surgically treated oral squamous cell carcinoma: Advances in survival in fifteen years of follow up

Retrospectively to evaluate the influence of radiochemotherapy (RCT) in the treatment of surgically and non-surgically treated Oral Squamous Cell Carcinoma (OSCC). We analysed 934 patients treated in Hospital Haroldo Juaçaba (2000-2014; 15 years of study) by extraction of data type of cancer, locali...

description Retrospectively to evaluate the influence of radiochemotherapy (RCT) in the treatment of surgically and non-surgically treated Oral Squamous Cell Carcinoma (OSCC). We analysed 934 patients treated in Hospital Haroldo Juaçaba (2000-2014; 15 years of study) by extraction of data type of cancer, localization of tumour, sex, age, race, education level, risk factors (smoking and alcohol use), year of diagnosis, TNM stage, therapeutic approach, health system used (public or private) and overall survival (OS). Surgically and non-surgically treated OSCC were compared by chi-square and Fisher's exact tests, and their prognostic factors were analysed by log-rank Mantel-Cox plus Cox regression tests (SPSS 20.0,
