上海石化地区老年人血吸虫病相关性结直肠癌临床病理特征及预后分析

目的 探讨血吸虫病对老年人结直肠癌组织学分型、分化程度、浸润深度、淋巴结转移等恶性生物学行为以及预后的影响.方法 收集我院2004年1月至2010年12月间60岁及以上老年人结直肠癌根治标本184例,分为两组:血吸虫病相关结直肠癌(colorectal carcinoma with schistosomiasia,CRCS)组102例,单纯结直肠癌(colorectal carcinoma,CRC)组82例.以CRC组为对照,分析血吸虫病对老年人结直肠癌临床病理特征的影响.同时,收集2004年1月至2006年12月间40例老年人结直肠癌预后资料并进行相关分析.结果 184例老年人结直肠癌中55.4％(102/184)合并血吸虫病.与CRC组比较,老年人结直肠癌发生部位、生长方式、分化程度、浸润深度、淋巴结转移以及TNM分期与血吸虫病密切相关(x2值分别为16.53、10.81、10.46、6.71、3.90、5.73,均P＜0.05).生存分析发现血吸虫病对老年人结直肠癌患者生存时间影响不明显(x2=0.14,P＞0.05).结论 合并血吸虫病与老年人结直肠癌的恶性生物学行为有关,但对术后生存时间无显著影响.

Colorectal carcinoma with schistosomiasis among elderly people in the district of petrochemical industry in Shanghai: Analysis of clinical pathological characteristics and prognosis

Objective To investigate the effects of schistosomiasis on malignant bio-behaviors including histological types,differentiation grade,inasie depth,lymphnode metastasis and prognosis of colorectal carcinoma among elderly people in the district of petrochemical industry,Shanghai.Methods A total of 184 cases (aged 60 years and over) with specimens of colorectal cancer were collected from January 2004 to December 2010.These specimens were divided into colorectal carcinoma with schistosomiasis (CRCS) group (102 cases) and simple colorectal carcinoma (CRC) as control group (82 cases).The prognostic data of 40 elderly cases with colorectal carcinoma from January 2004 to December 2006 were simultaneously selected and analysed Results Totally 55.4％ (102/184) cases exhibited coexistent schistosomiasis with colorectal carcinoma.lesion site(x2=16.53),growth pattern(x2 =10.81 ),differentiation degree(x2 =10.46),infiltration degree(x2 =6.71),lymph node metastasis(x2 =3.90),and TNM staging(x2=5.73) in CRCS group were closely related to schistosomiasis compared with CRC group (P＜0.05).Survival curve analysis showed that there was no significant effect of schistosomiasis on the survival time of elderly patients with colorectal carcinoma (x2 =0.14,P＞0.05).Conclusions The coexistent schistosomiasis may be associated with the malignant bio-behaviors of colorectal carcinoma among the elderly,but have no significant influence on the survival time after operation.
