围手术期化疗加外科手术治疗晚期胃癌

目的 探讨围手术期化疗加外科手术治疗晚期胃癌的效果.方法 2006年3月到2009年9月共24例晚期胃癌患者入组,其中ⅣM0期14例,Ⅳ M1期10例;其中包括肝转移5例,腹膜种植转移4例,肺转移1例.予紫杉醇+顺铂+5-氟尿嘧啶(PCF)或表阿霉素+顺铂+5-氟尿嘧啶(ECF)方案化疗2～4疗程,然后手术治疗,手术后继续术前方案化疗2～4疗程.结果 本组中7例未进行手术治疗,其中4例因疾病进展放弃手术,另外3例因其他原因自动放弃手术治疗;17例进行手术治疗,其中16例达到R0切除,R0切除率为94%;完成术前化疗的病例中总临床反应率为75%,病理总反应率为82%;59%(10例)患者血清CEA和CA199水平恢复至正常;71%(12/17)病例术后病理分期明显下降;患者Ⅲ～Ⅳ级粒细胞减少、血小板减少、贫血的发生率分别为79%、8%、13%,2例Ⅲ～Ⅳ级粒细胞减少伴发热,Ⅲ～Ⅳ级恶心、呕吐发生率为54%;无治疗相关的死亡病例.结论 对部分晚期胃癌可考虑行术前化疗及有计划的外科手术治疗.

Combination perioperative chemotherapy and surgery for the treatment of advanced gastric cancer

Objective To investigate the feasibility and safety of designed perioperative surgical treatment for advanced gastric cancer.Method From March 2006 to Sep.2009,24 patients with advanced gastric cancer were enrolled for this study,of which 14 cases were graded as Ⅳ M0,10 as Ⅳ M1,including liver metastasis in 5 cases,peritoneal seeding in 4 and lung metastasis in 1.All patients received 2-4 cycles of chemotherapy of PCF or ECF regimen,followed by intended surgical resection and postoperative 2-3 cycles of adjuvant chemotherapy of the same regimen as used during the preoperative course.Result Seven Cases abandoned surgical therapy,a total of 17 cases completed preoperative chemotherapy,surgical resection and postoperative chemotherapy.R0 resection was achieved in 16 cases(94%).There was no perioperative mortality,and total clinical response rate was 75%,overall pathological response rate was 82%.In 59% surgical cases (10 cases) serum CEA and CA199 has returned to normal;In 71%patients tumor pathological stage degraded at the cost of Ⅲ-Ⅳ grade of neutropenia,thrombocytopenia,anemia,severe nausea and vomiting in 79%,8%,13%,and 54% cases respectively.Fever was encountered in 2 cases with grade Ⅲ-Ⅳ neutropenia.Conclusion Designed perioperative chemotherapy regimen renders advanced gastric carcinoma patients operable at the cost of acceptable complications.
