Weight loss in patients with cancer is common and associated with a poorer survival and quality of life. Benefits from nutritional interventions are unclear. The present study assessed the effect of dietary advice and/or oral nutritional supplements on survival, nutritional endpoints and quality of life in patients with weight loss receiving palliative chemotherapy for gastrointestinal and non-small cell lung cancers or mesothelioma.
Participants were randomly assigned to receive no intervention, dietary advice, a nutritional supplement or dietary advice plus supplement before the start of chemotherapy. Patients were followed for 1 year. Survival, nutritional status and quality of life were assessed.
In total, 256 men and 102 women (median age, 66 years; range 24-88 years) with gastrointestinal (n = 277) and lung (n = 81) cancers were recruited. Median (range) follow-up was 6 (0-49) months. One-year survival was 38.6% (95% confidence interval 33.3-43.9). No differences in survival, weight or quality of life between groups were seen. Patients surviving beyond 26 weeks experienced significant weight gain from baseline to 12 weeks, although this was independent of nutritional intervention.
Simple nutritional interventions did not improve clinical or nutritional outcomes or quality of life. Weight gain predicted a longer survival but occurred independently of nutritional intervention.
癌症患者体重减轻较为常见,与生存质量和生存时间降低相关。营养干预的获益尚不清楚。本研究评估了在接受姑息性化疗的胃肠道和非小细胞肺癌或间皮瘤伴体重减轻的患者中,饮食建议和/或口服营养补充对生存、营养终点和生活质量的影响。
参与者被随机分配在化疗前接受无干预、饮食建议、营养补充或饮食建议加补充。患者随访 1 年。评估生存、营养状况和生活质量。
共纳入 277 例胃肠道癌和 81 例肺癌患者(男性 256 例,女性 102 例;中位年龄 66 岁;范围 24-88 岁)。中位(范围)随访时间为 6(0-49)个月。1 年生存率为 38.6%(95%置信区间 33.3-43.9)。各组间生存、体重或生活质量无差异。存活超过 26 周的患者从基线到 12 周体重显著增加,尽管这与营养干预无关。
简单的营养干预措施并不能改善临床或营养结局或生活质量。体重增加预示着更长的生存时间,但独立于营养干预。
