The role of nutritional counselling (NC) with or without oral nutritional supplements (ONS) in patients receiving chemoradiotherapy (CRT) for head and neck cancer (HNC) still remains to be clearly defined, particularly with regard to CRT-related toxicity.
Patients undergoing CRT for HNC received NC by the dietitian within the first 4 days of radiotherapy and weekly for the course of radiotherapy (approximately 6 weeks). A weekly supply of oral nutrition supplements [1560 kJ (373 kcal) per 100 g] for up to 3 months was provided to all patients.
Twenty-one patients completed CRT. Mucositis G3 developed in seven (33.3%) patients, whereas mucositis G4 was absent. Dysphagia was present before the start of treatment in four patients. In the remaining 17 patients, dysphagia G3 developed during/at the end of treatment in five cases. The percentage of patients interrupting anti-neoplastic treatment for was 28% for ≥6 days, 28% for 3-5 days and 44% for 0-2 days. Mucositis G3 frequency was lower in patients with a baseline body mass index (BMI, kg m(-2) ) ≥25 (two out of 12; 16.6%) than in patients with BMI <25 (five out of nine; 55.5%) (P = 0.161) and in patients with a baseline mid arm circumference >30 cm than in those with a mid arm circumference in the range 28.1-30 cm and <28 cm, and higher in patients with a greater weight loss and a greater reduction of serum albumin and mid arm circumference.
Nutritional counselling and ONS are associated with relatively low CRT-related toxicity and with mild deterioration of nutritional parameters.
营养咨询(NC)联合或不联合口服营养补充(ONS)在头颈部癌症(HNC)患者接受放化疗(CRT)中的作用仍有待明确界定,尤其是在 CRT 相关毒性方面。
接受 HNC CRT 的患者在放疗开始后的第 4 天内由营养师进行 NC,并在放疗期间每周进行一次(大约 6 周)。所有患者均提供每周供应的口服营养补充剂(每 100g 含 1560kJ[373kcal]热量),持续 3 个月。
21 例患者完成 CRT。7 例(33.3%)患者出现 3 级黏膜炎,无 4 级黏膜炎。4 例患者在开始治疗前存在吞咽困难。在其余 17 例患者中,5 例在治疗期间/结束时出现 3 级吞咽困难。因≥6 天、3-5 天和 0-2 天中断抗肿瘤治疗的患者比例分别为 28%、28%和 44%。基线体质量指数(BMI,kg/m²)≥25 的患者中,3 级黏膜炎的发生率低于 BMI<25 的患者(12 例中 2 例[16.6%]比 9 例中 5 例[55.5%])(P=0.161);基线中臂围>30cm 的患者发生率低于中臂围在 28.1-30cm 和<28cm 的患者,且与体重下降、血清白蛋白和中臂围减少程度呈正相关。
营养咨询和 ONS 与相对较低的 CRT 相关毒性以及营养参数的轻度恶化相关。
