This study was carried out to determine if markers of nutritional status predict for locoregional failure following intensity-modulated radiation therapy (IMRT) with concurrent chemoradiotherapy (CCRT) for squamous cell carcinoma of the head and neck (SCCHN).
We performed a retrospective chart review of 78 patients with SCCHN who received definitive CCRT. We compared patient factors, tumor characteristics, and nutritional status indicators between patients with and without locoregional failure.
Fifteen of 78 patients (19%) experienced locoregional failure. Median follow-up for live patients was 38 months. On univariate analysis, pretreatment percentage of ideal body weight (%IBW) (p < .01), pretreatment hemoglobin (p = .04), and treatment duration (p < .01) were significant predictors of failure. On multivariate analysis, pretreatment %IBW (p = .04) and treatment time (p < .01) remained statistically significant.
Although treatment time is an accepted risk factor for failure, differences in outcome for patients with head and neck cancer undergoing definitive CCRT based on pretreatment %IBW should be examined further.
本研究旨在确定营养状况标志物是否可预测接受调强放疗(IMRT)联合同期放化疗(CCRT)的头颈部鳞状细胞癌(SCCHN)患者的局部区域失败。
我们对 78 例接受根治性 CCRT 的 SCCHN 患者进行了回顾性图表审查。我们比较了有和无局部区域失败患者的患者因素、肿瘤特征和营养状况指标。
78 例患者中有 15 例(19%)发生局部区域失败。存活患者的中位随访时间为 38 个月。单因素分析显示,治疗前理想体重百分比(%IBW)(p <.01)、治疗前血红蛋白(p =.04)和治疗时间(p <.01)是失败的显著预测因素。多因素分析显示,治疗前%IBW(p =.04)和治疗时间(p <.01)仍然具有统计学意义。
尽管治疗时间是失败的公认危险因素,但基于治疗前%IBW ,接受根治性 CCRT 的头颈部癌症患者的治疗结果存在差异,应进一步研究。
