【摘要】 目的 对照研究30例白及混合微粒、125碘(125I)在进展期胃癌手术中组织间近距离持续低能量放化疗和全身静脉化疗的近期疗效、远期疗效和毒副反应。方法 随机分为胃癌手术、近距离放化疗组(治疗组)30例和静脉化疗组(对照组)30例,记录观察近期疗效和毒副反应,随访患者生存期。采用Kaplan-Meier法估计生存函数,Log rank检验两组生存函数的差异。结果 近期疗效两组基本接近,毒副反应中恶心、呕吐、骨髓抑制症状、生存质量治疗组明显低于对照组。中位生存期和1年生存率显著高于对照组。结论 对进展期胃癌患者进行组织间近距离持续低能量放化疗,可提高生存质量,延长患者生存期。

The research on Baiji mixed particle and 125I in radiotherapy and chemotherapy among tissues during the progressive stage of stomach cancer
【Abstract】 Objective To study 30 examples about the recent curative effect, long-term curative effect and reaction to poison of Baiji mixed particle and 125I, by continuous radiotherapy and chemotherapy with low energy among tissues in a near distance and chemotherapy during the operation for stomach cancer which is in progressive stage.Methods It's divided at random into the group of radiotherapy and chemotherapy in a near distance in an operation for stomach cancer (the treatment group), there are 30 examples and chemotherapy via veins (the contrast group) also including 30 examples, recording and observing the recent curative effect and reaction to poison, making attendant interview about patient's lifespan.The Kaplan-Meier method is adopted to estimate the function of survival, Log rank are used to inspect the distinction of the survival function between the two groups. Results The two groups in recent curative effect get close basically. Concerning the symptom of nausea, vomiting and of marrow inhibition, it's apparent that the quality of existence in the treatment group is lower than that of the contrast group. Lifespan of medium time and the survival rate in 3 years are remarkably higher than those of the contrast group, by the inspection of statistics, P< 0.05, there is a noticeable difference. Conclusion Carry out continuous radiotherapy and chemotherapy with low energy among tissues in a near distance on patient suffering stomach cancer, which is in progressive stage,can improve the quality of existence and prolonged the patient's lifespan.

1 材料与方法
1.1 一般资料 2002年6月~2005年8月间住院病人60例,男47例,女13例,平均年龄48.6岁。随机分为进展期胃癌近距离放化疗组(治疗组)30例和全身静脉化疗组(对照组)30例,其中进展期胃癌Ⅱ期16例,Ⅲ期14例;对照组30例,其中Ⅱ期18例,Ⅲ期12例。
1.2 病例入组标准 (1)患者年龄≤70岁,手术为完全性即根治性切除;(2)手术前后经病理学明确诊断者;(3)KPS评分>60分,预期生存>6个月;(4)骨髓造血、肝肾功能无明显异常;(5)治疗组患者手术前未行放化疗者。
1.3 治疗方法 进展期胃癌近距离放化疗方法:采取硬膜外或全身麻醉进行腹部消化道系统恶性肿瘤根治性切除术,术中将白及混合微粒(由陕西中医学院制剂研究中心提供,其中白及粉2g内含顺铂20mg,顺铂由齐鲁制药厂生产,产品批号:2001142、0401001)根据肿瘤切除范围大小,将2~4g涂撒在肿瘤切除后病灶区域。应用专用穿刺针将125I放射性离子(由中国原子能科学研究院提供)置入肿瘤切除后病变组织周围无血管区,深度为< 1cm,置入数量为20~30粒,粒子与粒子间距为1cm。
1.4 近期疗效及毒副作用判定标准 近期疗效按照WHO标准分为:完全缓解(CR)、部分缓解(PR)、无变化(NC)和病情进展(PD)。毒副作用按WHO1981年统一标准评价[1]。
1.5 生存分析方法 采用Kaplan-Meier法估计生存函数[2],按公式依次计算每个有死亡时刻的生存率的近似值,得到2条阶梯形曲线。Log rank检验比较两组生存数据,计算χ2值。对数据进行回归分析,分别读取中位生存期和1年生存率。其余资料统计方法采取t检验或χ2检验。
2 结果
2.1 两组一般资料比较 两组患者年龄、KPS评分及病种组成差异均无显著性。截至2005年8月30日,所观察病例中仍存活57例(治疗组29例,对照组28例),失访3例(治疗组1例,对照组2例)。
2.2 疗效比较 近期疗效比较:治疗组CR 16例,PR 8例,NC 5例,PD 1例,总有效率79.9%。对照组 CR 11例,PR 6例,NC 7例,PD 6例,总有效率56.6%;远期疗效比较:治疗组CR 14例,PR 7例,NC 5例,PD 3例,总有效率为69.9%。对照组 CR 4例,PR 3例,NC 12例,PD 8例,总有效率29.9%。两组总有效率经χ2检验差异无显著性(P< 0.05),见表1。
