Radiotherapy is an effective treatment for head and neck cancers but patients often experience side effects which lead to weight loss. Nutrition intervention in the form of counselling or oral nutrition support (ONS) is frequently needed for these patients. For some patients, tube feeding is required to minimise weight loss during treatment.
Data was collected on 48 patients who received radiotherapy to the head and neck region over a nine-month period (June 2009-March 2010). Retrospective data collection was commenced in July 2010. Each patient's Diet Therapy Department record was reviewed. Main outcome measures were: 1) type of nutrition support; 2) percentage weight change during treatment; and 3) Patient-Generated Subjective Global Assessment Global (PG-SGA) rating.
On initial assessment 28 (77.8%) patients were classified as well nourished using the PG-SGA. Mean weight loss during radiotherapy was 5.74%. Risk factors for the need for ONS and enteral nutrition support (ENS) were older age, presence of nutrition impact symptoms, high-risk tumour sites, advanced disease and chemotherapy. No significant difference was shown in weight loss between ONS and ENS groups.
This study identified the need for early dietetic intervention for high nutritional risk groups of head and neck cancer patients to prevent significant weight loss. Pre-treatment nutritional status did not influence weight loss during treatment. ONS alone cannot prevent significant weight loss in patients with multiple nutrition impact symptoms. Early enteral feeding should be considered in this group of patients.
放射治疗是头颈部癌症的有效治疗方法,但患者常出现导致体重减轻的副作用。这些患者经常需要以咨询或口服营养支持(ONS)形式进行营养干预。对于一些患者,需要管饲以尽量减少治疗期间的体重减轻。
收集了48例在9个月期间(2009年6月至2010年3月)接受头颈部放疗的患者的数据。回顾性数据收集于2010年7月开始。查阅了每位患者的饮食治疗科记录。主要结局指标为:1)营养支持类型;2)治疗期间体重变化百分比;3)患者主观整体评定法总体评分(PG-SGA)。
初始评估时,使用PG-SGA将28例(77.8%)患者分类为营养良好。放疗期间平均体重减轻5.74%。ONS和肠内营养支持(ENS)需求的危险因素为年龄较大、存在营养影响症状、高危肿瘤部位、疾病晚期和化疗。ONS组和ENS组之间的体重减轻无显著差异。
本研究确定头颈部癌症高营养风险组患者需要早期饮食干预以防止显著体重减轻。治疗前营养状况不影响治疗期间的体重减轻。单独ONS不能防止有多种营养影响症状患者的显著体重减轻。对于该组患者应考虑早期肠内喂养。
