[摘要]目的探讨甘氨双唑钠(CMNa)在早期乳腺癌保乳术加术后放疗中是否有增敏作用。方法2009年12月至2011年10月,对45例早期乳腺癌患者行保乳术,术后随机分为A、B两组进行放疗;A组放疗前不使用CMNa,B组放疗前使用CMNa,并按CMNa放疗增敏比减少放射剂量。手术后6~24个月随访,观察术后治疗效果、美容效果及不良反应。结果A、B两组在治疗效果、美容效果、不良反应三方面均无统计学差异。结论甘氨双唑钠在早期乳腺癌保乳术加术后放疗中确实有增敏作用,没有增加放疗的不良反应,值得在放疗领域推广使用。

[Abstract]Objective: TO study whether sodiumglycididazole(CMNa)has sensitizing effect in radiotherapy after breast conserving surgery for people who have early breast cancer. Method: 45 cases with early breast carcinoma were divided into A,B two group according to the age after breast conserving surgery, and they all were given radiotherapy. A group before radiotherapy does not use CMNa,B group before radiotherapy use CMNa and B group reduced radiation dose according to SER of CMNa. After 6 to 24 months follow-up,therapeutic and beautifying effect as well as advertise effect of the treatment modality were observed. Result:A, B two group effects in therapeutic and beautifying effect as well as advertise effect of the treatment of no statistical difference. Conclusion: CMNa dose has sensitizing effect in radiotherapy after breast conserving surgery for people who have early breast cancer and dose not increase in side effects. In the end, the medicine is recommendable in radiation field.

1材料与方法
1.1 病例选择
2009年12月至2011年10月,我院收治Ⅰ~Ⅱ期乳腺癌病人45例,全为女性,术前均行钼靶X线,B超及MRI检查,肿瘤最大直径4cm,均获病理证实,年龄29~68岁,中位年龄40岁,一般临床特征:

1.2 手术方法
45例患者均行肿瘤扩大切除术及前哨淋巴结活检术。乳房肿块和腋窝分别作切口。腋窝先行前哨淋巴结活检,采用亚甲蓝示踪法,切除淋巴结行快速冰冻切片检查,如阳性行腋窝淋巴结清扫,否则不做清扫。
1.3 用药方法
甘氨双唑钠每次按人体表面积,800mg∕m2用药,用生理盐水100ml溶解后,于30分钟内静脉滴注完。60min内进行常规放疗。隔天用药至治疗结束为止。
1.4 术后放疗
全部病人于术后2个月给予放射治疗。
1.4.1 所有病人均采用仰卧位于乳腺定位托架上,托架的各种各参数设置必须保证病人体位舒适,被照射靶区充分暴露并使胸骨呈相对水平位置,病人体表标志性位置放置金属标记。保乳术后照射的靶区域包括全乳,瘤床和区域淋巴结。病例均为病理证实Ⅰ、Ⅱ期乳腺癌病人。给予区域淋巴结放疗,照射野包括腋顶,锁骨上和内乳;腋窝淋巴结1~3个转移者,对原发肿瘤位于外象限者可单纯照射锁骨上区,对位于内象限者,行内乳区加锁骨上照射。切线照射一般采用内,外切线野半束照射,照射靶区边界一般定界为:内界为胸骨中线,外界为腋中线,下界为乳房下1~2cm,上界在胸廓入口或与锁骨上野的下界相接 ......
