目的 :探讨鼻咽癌患者放疗前后的营养状况 ,为合理调配膳食 ,使患者更好地接受化疗 ,早日康复提供依据。方法 :对 80例患者放疗前后营养状况 ,通过计算平均每人每日能量及营养素 ,体检及实验室检查结果进行评定。结果 :患者治疗前能量及各种营养素摄入基本达到推荐营养素摄入量 (RNI) ,治疗后除抗坏血酸达到RNI的 97 0 %外 ,男女患者能量摄入分别为 82 5 6 %和 84 2 4 % (P <0 0 1) ,其它营养素摄入量占RNI 38 5 3%～ 84 4 3% ,达不到平衡膳食的要求。放疗后男女患者体重分别下降 10 0 4 %和 7 6 8%。Hb、RBC、Lym和ALB偏低 (P <0 0 5～ 0 0 1)。结论 :放疗后患者普遍存在能量和营养素摄入不足、体重下降、贫血、低蛋白和免疫力下降等潜在性营养不足问题。
Objective: To investigate the nutritional status of patients with nasopharyngeal carcinoma before and after radiotherapy, in order to rationally formulate the diet so that patients can receive better chemotherapy and provide basis for early recovery. Methods: The nutritional status of 80 patients before and after radiotherapy, by calculating the average daily energy and nutrients per person, physical examination and laboratory test results were assessed. Results: Before treatment, the intake of energy and various nutrients basically reached the recommended nutrient intake (RNI). After the treatment, the energy intake of male and female patients was 82.56% and 84 2 4, respectively, except for ascorbic acid reaching 97.0% of RNI % (P <0 0 1). The intake of other nutrients accounted for 38.3% ~ 84.43% of RNI, which could not reach the requirement of balanced diet. After radiotherapy, the body weight of both men and women decreased by 104.04% and 76.8% respectively. Hb, RBC, Lym and ALB were lower (P <0 05 ~ 0 0 1). CONCLUSION: Potential undernutrition, such as inadequate energy and nutrient intake, weight loss, anemia, low protein, and decreased immunity, are common in patients after radiotherapy.
