This study aimed to analyze the specific five-year oral cancer survival rate and associated factors in Brazil. This was a retrospective cohort study using the Oncological Database as the source, with probabilistic-deterministic linkage of all the records for authorization of radiotherapy and/or chemotherapy in the Unified National Health System from 2000 to 2006, generating a single record for each patient. The current study included patients diagnosed with oral cancer from 2002 to 2003 (except for cancer of lip), and ranging from 19 to 100 years of age (N = 6,180). Specific five-year survival was 60%. Decreased specific survival was associated with: age > 40 years; stages III or IV; location on the tongue, floor of the mouth, or base of the tongue; not performing surgical treatment, performing only chemotherapy or radiotherapy and chemotherapy; and residence in certain States of Brazil. The results emphasize the need to include assessment of regional disparities as a possibility for increasing health interventions and improving survival.
本研究旨在分析巴西口腔癌患者的特定五年生存率及相关因素。这是一项回顾性队列研究，以肿瘤数据库为数据源，通过概率确定性关联2000年至2006年巴西统一国家卫生系统中所有放疗和/或化疗授权记录，为每位患者生成单一记录。本研究纳入了2002年至2003年诊断为口腔癌（唇癌除外）、年龄在19岁至100岁之间的患者（N = 6180）。特定五年生存率为60%。特定生存率降低与以下因素相关：年龄>40岁；III期或IV期；肿瘤位于舌部、口底或舌根；未进行手术治疗、仅进行化疗或放疗及化疗；以及居住在巴西某些州。研究结果强调，有必要将区域差异评估纳入考量，以此作为加强健康干预措施和提高生存率的一种途径。
