Sarcopenia is associated with treatment-related complications and shorter overall survival in patients with cancer. Psoas area indices were calculated for 121 patients with lymphoma who underwent autologous transplant. Controlling for age, body mass index, comorbidities and performance status for the 73 men included, the hazard ratio (95% confidence interval, CI) for non-relapse mortality was 2.37 (1.01, 5.58), p = 0.048 for every 100 unit decrease in total psoas index and 2.67 (1.04, 6.86), p = 0.041 for every 100 unit decrease in lean psoas index. Men with a lower total psoas index experienced more complications (p = 0.001) and spent more days in hospital (p = 0.03) during the transplant admission. A strong association existed between sarcopenia and number of hospital days in the 100 days following transplant among both men (p < 0.0001) and women (p < 0.0001). Sarcopenia may impact negative outcomes after autologous transplant thereby serving as a potentially modifiable predictor of outcomes and aiding in treatment selection.
肌肉减少症与癌症患者的治疗相关并发症及较短的总生存期有关。对121例接受自体移植的淋巴瘤患者计算腰大肌面积指数。在纳入的73名男性中,在控制年龄、体重指数、合并症和体能状态后,总腰大肌指数每降低100单位,非复发死亡率的风险比(95%置信区间,CI)为2.37(1.01,5.58),p = 0.048;瘦腰大肌指数每降低100单位,风险比为2.67(1.04,6.86),p = 0.041。总腰大肌指数较低的男性在移植住院期间出现更多并发症(p = 0.001),住院天数更多(p = 0.03)。在男性(p < 0.0001)和女性(p < 0.0001)中,移植后100天内肌肉减少症与住院天数之间均存在密切关联。肌肉减少症可能会影响自体移植后的不良结局,从而成为结局的潜在可改变预测指标,并有助于治疗选择。
