E.术前大剂量化疗和放疗+肿瘤刮除+术后大剂量化疗和放疗

答案

参考答案:C

解析:[考点] 恶性骨肿瘤
[分析] 骨肉瘤是最常见的恶性骨肿瘤,好发于青少年,好发部位是膝关节上下及肱骨近端的干骺端。骨肉瘤肺转移发生率极高。既往虽行根治性切除术,但5年存活率不高。近年来由于早期诊断和化疗的迅速发展,对本例属于G2T1-2M0的患者,术前大剂量化疗,然后根据肿瘤浸润范围作根治性切除,术后继续大剂量化疗。如已有肺转移,属G2T1-2M1者,除上述治疗外,还可行手术切除转移灶,5年存活率提高至50%以上。

Soon three   31  people walked out with all the   32  their arms could hold. They were   33  that , if they needed to come back again , they were to ask and not just grab.
