体质指数(BMI)与头颈癌结局相关性差异显著。该文旨在评估BMI与诊断或早期成人头颈癌结果之间的相关性。纳入研究的样本为加拿大多伦多玛格丽特王子肿瘤中心头颈鳞癌患者,检测指标包括烟草和酒精的使用、病情状态、并发症及BMI指数。结果:平均随访时间2.5年。在1279例患者中,诊断为超重的患者生存率显著高于正常体重患者(P=0.001)。相应地,诊断为低体重的患者生存率更低(P< Body mass index (BMI) and head and neck cancer outcome was significantly different. The aim of this paper is to evaluate the association between BMI and diagnosis or early head and neck cancer in adults. The included samples were patients with head and neck squamous cell carcinoma at the Margaret Tumor Center in Toronto, Canada. The testing parameters included tobacco and alcohol use, disease status, complications and BMI. Results: The mean follow-up time was 2.5 years. Among 1279 patients, those diagnosed as overweight had significantly higher survival rates than those with normal weight (P = 0.001). Correspondingly, patients who were diagnosed with low body weight had a lower survival rate (P <
