METHODS: From June 2005 to December 2007, 23 patients with local advanced pancreatic cancer were divided into two groups randomly, namely, combined treatment group (n = 12) and control group (n = 11). The combined treatment group received the two-pathway chemotherapy (regional arterial infusion and systemic venous chemotherapy) combined with gamma-ray stereotactic radiotherapy. The control group were only treated with the two-pathway chemotherapy. The curative effect, relief extent of pain, life span and the adverse reaction were compared in the course of treatment between the two groups. RESULTS: The proportion of CR and PR in the combined treatment group was 75.0%, much higher than 27.3% of the control group. The survival rates at 6 mo and 9 mo were 83.3% and 75.0% in the combined treatment group, similar to 72.7% and 45.5% of the control group. But the 12 months’ survival rate of combined treatment group was 50% which was higher than the control group. The average life span of the combined treatment group was 13.1 mo, higher than that of the control group, which was 8.7 mo (P < 0.05). The data of tumor marker CA199 of combined treatment group dropped significantly compared with that of control group (P < 0.05). Abdominal pain in combined treatment group was relieved more than that in control group (P < 0.05). And the adverse effect between two groups had no significant difference (P > 0.05). CONCLUSION: The therapeutic model of two-pathway chemotherapy combined with gamma-ray stereotactic radiotherapy could be considered one of choice for the patients with local advanced pancreatic cancer.

Shijie Huaren Xiaohua Zazhi 2009; 17(18): 1888-1893 摘要 目的: 探讨双途径化疗联合三维立体定向伽玛刀治疗局部晚期胰腺癌的临床价值. 方法: 2005-06/2007-12我科选择性收治局部晚期胰腺癌患者23例, 均经穿刺病理学检查证实或经CT、MRI、肿瘤标志物(CA199、CEA等)临床诊断. 患者随机分为2组: 联合治疗组(n = 12)采用双途径化疗(区域动脉灌注和全身静脉化疗)联合三维立体定向伽玛刀治疗; 对照组(n = 11)仅采用双途径化疗. 对比2组患者治疗后疗效、疼痛缓解程度、生存期、不良反应. 结果: 联合治疗组完全缓解和部分缓解率明显高于对照组(75.0% vs 27.3%, P<0.01); 联合治疗组患者的6、9 mo生存率分别为83.3%和75.0%, 与对照组72.7%和45.5%比较, 无统计学差异; 联合治疗组12 mo生存率50.0%(中位生存期13.1 mo)明显高于对照组9.1%(中位生存期8.7 mo)(P<0.05); 联合治疗组肿瘤标志物CA199的表达明显降低(P<0.05); 联合治疗组比对照组能够较大程度改善患者的疼痛症状(P<0.05); 2组治疗模式的不良反应无统计学差异. 结论: 双途径化疗联合三维立体定向伽玛刀是治疗局部晚期胰腺癌的较好方法. 关键词: 晚期胰腺癌; 双途径化疗; 三维立体定向伽玛刀 夏念信, 邱宝安, 温居一, 祝建勇, 刘澎. 双途径化疗联合伽玛刀治疗局部晚期胰腺癌12例. 世界华人消化杂志 2009; 17(18): 1888-1893 http://www.wjgnet.com/1009-3079/17/1888.asp

图1 胰腺癌合并肝转移治疗前后CT影像比较. A: 治疗前: 增强CT显示胰腺颈体部不规则实性肿块, 大小约4 cm×4.5 cm, 无强化, 胰头不大, 肝脏多发强化结节. (外院)肝穿刺病理诊断肝脏转移性腺癌; B: 一个疗程后: 胰腺颈体部不规则实性肿块缩小, 大小约3 cm×3.5 cm, 无强化, 胰头不大, 肝脏多发结节缩小, 部分结节消失; C: 双途径化疗联合三维立体定向伽玛刀治疗后3 mo. 与图A相比, 胰腺颈体部包块基本消失, 局部轻度水肿, 无异常强化. 肝右叶原多发结节基本消失(截止投稿, 患者带瘤存活42 mo余, 无胸腹水, 生活质量高).
图2 胰腺癌合并肝多发转移治疗前后DSA肝动脉造影影像比较. A: 治疗前DSA: 肝脏多发转移结节浓染区, 与CT多血供性结节表现一致; B: 同期肝动脉化疗栓塞后, 肝脏多血供转移结节染色基本消失, 仅显示正常肝动脉及分支; C: 化疗一个疗程后: DSA显示肝右下叶未见明显浓染结节, 仅肝脏右上叶有少许浅淡浓染结节; D: 同期肝动脉化疗栓塞后, 肝脏多血供转移结节染色基本消失, 仅显示正常腹腔干动脉、肠系膜上动脉及脾动脉.
表1 两组患者累积生存率比较
背景资料 胰腺癌的发病率逐年上升, 大多数患者确诊时已经失去手术机会; 化疗和放疗等非手术模式是局部晚期胰腺癌主要的治疗方法, 效果均不理想. 双途径化疗(区域性动脉灌注联合全身静脉化疗)以及三维立体定向伽玛刀治疗为近年来新兴的治疗方法. 同行评议者 崔云甫, 教授, 哈尔滨医科大学第二附属医院普外一科 相关报道 张明 et al报道双途径化疗治疗中晚期胰腺癌能提高患者中位生存期和临床获益率, 优于单纯区域性动脉灌注化疗. 张丽萍 et al报道伽玛刀联合热化疗治疗局部晚期胰腺癌近期疗效满意, 能提高患者的生活质量和生存期. 创新盘点 单纯化疗或放疗、放化疗结合、化疗与靶向生物治疗等非手术模式是局部晚期胰腺癌主要的治疗手段. 双途径化疗联合三维立体定向伽玛刀治疗局部晚期胰腺癌, 临床研究报道尚属首次. 应用要点 双途径化疗联合三维立体定向伽玛刀是治疗局部晚期胰腺癌的较好方法.
