JAMA:增加蔬菜摄入量与早期前列腺癌患者进展风险

2020-01-15 MedSci MedSci原创

在接受积极监测的早期前列腺癌患者中,增加蔬菜摄入量的行为干预并没有显著降低前列腺癌的进展风险。

富含蔬菜饮食对改善前列腺癌幸存者预后有益,近日研究人员考察了蔬菜饮食干预对早期前列腺癌男性癌症进展的影响。

MEAL研究在美国91家泌尿外科和肿瘤内科诊所开展,478名年龄在50至80岁的男性,经活检证实的前列腺癌患者参与,肿瘤分期cT2a期或更低,血清前列腺特异性抗原(PSA)水平低于10 ng/mL。患者随机接受行为干预,督促每日食用7种或更多蔬菜(MEAL干预;n=237)或对照(n=241)。研究的主要结果是疾病进展时间,进展定义为PSA水平为10 ng/mL或更高,PSA倍增时间小于3年或在后续前列腺活检中疾病升级(定义为肿瘤体积或级别增加)。

患者平均年龄64岁,平均PSA水平4.9ng/mL,443名患者(93%)纳入初步分析。有245个进展事件(干预组124例;对照组121例)。组间在进展时间上没有显著差异(未调整的危险比,0.96;调整后的危险比,0.97)。干预组和对照组24个月无进展百分比分别为43.5%和41.4%,差异为2.1%。
