摘要 骨肉瘤(osteosarcoma,OS)好发于15~25岁的青少年,并以男性患者居多,其发病率在儿童和青少年恶性肿瘤中居首位。0S好发于长骨干骺端、股骨远端和胫骨近端,具有很强的侵蚀性,常伴肺部转移。仅行手术切除治疗OS患者的存活率不足20%。但与化学治疗联用后。局部病变OS患者存活率提升至70%,表明化疗对治疗OS的有效性和重要性。目前国内外以顺铂、多柔比星、异环磷酰胺和甲氨蝶呤为基础抗化疗药物治疗OS。近年发现,化疗耐药是影响OS患者存活率进一步提高的重要原因之一。因此,探索骨肉瘤抗化学治疗的分子机制并找到相应的克服方式,对提高OS患者的生存率具有重要的意义。耐药性主要分为原发性和继发性耐药,本文就OS增强DNA修复、分裂周期相关基因表达和自噬相关等继发性化疗耐药分子机制做一简要综述。
