【摘要】：目的通过CT诊断,分析胃癌根治术后复发与转移的区域及规律。方法选取2009年6月至2014年6月胃癌患者共81例,均行胃癌根治性手术,随访期间CT发现存在局部区域复发或转移。分析术后复发与转移的区域及规律。用SPSS 19.0软件分析数据,以%表示计数资料,Logistic回归分析检验术后复发时间和临床病理特征和治疗之间的关系;P0.05,差异具有统计学意义。结果在81例术后复发患者中,局部区域复发率最高(37.04%),在18例伴有术后区域淋巴结转移的患者中,Ⅰ区10例,Ⅲ区3例,Ⅳ区1例,Ⅵ区4例。术后7~12个月复发率最高(41.98%)。截止至2015年9月30日,在胃癌根治术后复发的81例患者中,中位总生存时间(OS)为33.18个月,中位复发时间为19.94个月,复发后中位生存期为7.19个月。其中发生腹膜种植后,中位生存期最短,仅为4.24个月。单因素分析结果显示,与OS相关的临床病理因素包括年龄(P=0.024),Borrmann分型(P=0.017)、TNM分期(P=0.009)、淋巴结检出总数(P=0.022)、阳性淋巴结数(P=0.002)、治疗方式(P=0.026)和治疗依从性(P=0.035);与局部无复发生存期(LRFS)相关的临床病理因素包括淋巴结检出总数(P=0.012)、阳性淋巴结数(P=0.008)、治疗方式(P=0.034)和治疗依从性(P=0.016)。结论局部区域复发,特别是区域淋巴结转移是胃癌根治术后复发的主要形式,术后通过CT划分淋巴结转移区域对于放疗靶区确定具有一定指导意义。
[Abstract]:Objective to analyze the region and regularity of recurrence and metastasis of gastric cancer after radical resection by CT. Methods from June 2009 to June 2014, 81 patients with gastric cancer underwent radical operation. CT found local recurrence or metastasis during follow-up. The region and regularity of recurrence and metastasis after operation were analyzed. The data were analyzed by SPSS 19.0 software, and the counting data were expressed in%. Logistic regression analysis was used to test the relationship between postoperative recurrence time and clinicopathological features and treatment, and P0.05, the difference was statistically significant. Results among 81 patients with postoperative recurrence, the local recurrence rate was the highest (37.04%). Among 18 patients with regional lymph node metastasis, there were 10 cases in area 鈪，
