进展期胃癌术式选择及术中腹腔化疗探析

阐述晚期胃癌TNMⅣ期,其复发形式多见于腹膜播散性转移和种植,并影响预后之重要因素。即使进行根治术,亦仅称之为非治疗性切除术。进展期胃癌进行广泛淋巴清扫价值始终存在分歧和争议。侵出浆膜之患者其五年治疗率低下。肉眼腹膜种植者,腹腔游离癌细胞近乎100%。伴随侵出面积增大,其治疗率而降低。肿瘤标志物监测诸如TPA,CA724,CA242,CA199以及CEA等,睿智据理规范和启迪术式及术中化疗之实施,选定多元化特异性高的标志物检测,可提高敏感性,皆阳性者则诊断无疑。临床残留癌细胞是客观存在,术中第一时间强烈干预腹腔内置入抗癌药物为最理想。诸如MMC-CH,CDDP,Vp16以及区域性缓释化疗抗肿瘤植入剂Sinofuan等不乏为首选。晚期胃癌循规蹈矩进行D2或D3术式,难以达到期望阈值。D2术式不能提高患者生存率。D1,D2术式术后生存率统计学上分析无明显差异。淋巴清扫仅有助于病理分期确切性,偏倚扩大根治术,善其予后难以期待。

Surgical Procedure Selection and Intraoperative Intra-abdominal Chemotherapy for Patients with Advanced Gastric Cancer

Peritoneal dissemination is commonly found in stage 4 gastric cancer patients and it is a key factor in the prognosis of advanced gastric cancer.Radical resection for gastric cancer is still controversial and is con- sidered a palliative procedure.In patients with tumors penetrating through the serosa,the 5-year survival rate is low.Isolated cancer cells almost always exist when peritoneal metastasis is detectable by the naked eye. Patients with more tumor invasion out of the stomach have a lower survival r...
