Malnutrition at diagnosis is found in 10-50% of children with cancer in industrialized countries. In developing countries a large proportion of the normal paediatric population is undernourished and children with cancer often present late with advanced disease. Therefore it would be expected that many children with cancer are malnourished at admission. Malnutrition is associated with more severe chemotherapy toxicity and infectious complications.
All new paediatric oncology patients admitted in the Queen Elizabeth Central Hospital, Blantyre, Malawi between 1, January 2007 and 1, January 2008 were included. We documented age, clinical diagnosis, HIV status, weight, height, mid-upper-arm-circumference (MUAC) and triceps skinfold (TSF), and calculated arm muscle area (AMA). Nutritional data were compared with the 1978 NCHS growth curves.
Of 128 children, 70 (55.1%) had an AMA for age <5th percentile and 76 (59.3%) had a TSF and MUAC below the 5th percentile, both parameters indicating acute malnutrition. Fifty seven patients (44.5%) had a height for age <-2 SD (indicative of stunting), and 22 patients (17.2%) had a weight for height (WFH) <-2 SD.
Arm anthropometry shows that more than half of Malawian children with cancer are severely acutely malnourished at diagnosis. WFH, in children with large tumour masses, is less sensitive than arm anthropometry in detecting acute malnutrition. Forty-five percent of paediatric oncology patients in Malawi are stunted, making interpretation of weight for age (WFA) very difficult.
在工业化国家,10%至50%的癌症患儿在确诊时存在营养不良。在发展中国家,很大一部分正常儿童人口营养不良,癌症患儿往往就诊较晚且病情已发展至晚期。因此,可以预期许多癌症患儿在入院时就已营养不良。营养不良与更严重的化疗毒性和感染性并发症相关。
纳入2007年1月1日至2008年1月1日期间在马拉维布兰太尔伊丽莎白女王中央医院收治的所有新的儿科肿瘤患者。我们记录了年龄、临床诊断、艾滋病毒感染状况、体重、身高、上臂中部周长(MUAC)和三头肌皮褶厚度(TSF),并计算了手臂肌肉面积(AMA)。将营养数据与1978年美国国家卫生统计中心(NCHS)的生长曲线进行比较。
在128名儿童中,70名(55.1%)的年龄别AMA低于第5百分位数,76名(59.3%)的TSF和MUAC低于第5百分位数,这两个参数均表明存在急性营养不良。57名患者(44.5%)的年龄别身高<-2标准差(表明发育迟缓),22名患者(17.2%)的身高别体重(WFH)<-2标准差。
手臂人体测量显示,超过一半的马拉维癌症患儿在确诊时严重急性营养不良。对于肿瘤肿块较大的儿童,WFH在检测急性营养不良方面不如手臂人体测量敏感。马拉维45%的儿科肿瘤患者发育迟缓,这使得对年龄别体重(WFA)的解读非常困难。
