ABSTRACT
Objective To investigate the familial incidence of multiple primary carcinoma in Chinese hereditary nonpolyposis colorectal cancer patients (HNPCC) in Northeast China.Methods By family line investigation,multiple primary carcinoma (MPC) spectrum' s characteristics of 509 patients in 85 families registered in strict conformity with the HNPCC Amsterdam criteria Ⅱ were analyzed retrospectively.Results Of the 85 HNPCC families,multiple primary carcinoma developed in 55 patients in 25 families,among them 45 patients had metachronous carcinoma in 17 families,16 patients had synchronous carcinoma occurred in 12 families,6 patients with both synchronous carcinoma and metachronous carcinoma in 4 families.Conclusions Multiple primary carcinoma developed in significantly high incidence in Northeast China in Chinese hereditary nonpolyposis colorectal cancer patients,the most common MPC are colorectal cancer and endometrial cancer.
ABSTRACT
Objective To investigate the prognostic factots by analyzing clinicopathologlcal characteristics of 972 cases of colonic carcinoma. Methods Clinical and pathological data of 972 patients with colonic carcinoma treated surgically were studied by univariate and multivariate analysis,survival rate was calculated by life-table method and compared by Log-rank test. Results The univariate analysis indicated that the predictors of survival were age,perioperative blood transfusion, perioperative carcinoembryonic antigen(CEA)level,tumor gross type,depth of tumor invasion,lymphatic invasion,liver metastasis,extrahepatic metastasis,local recurrence、peritoneal seeding,pathological type,TNM stage and type of lymph node clearance.The multivariate analysis indicated that the independent predictors of suivival were age,periopemtive CEA level,tumor gross type,lymphatic invasion,liver metastasm,extrahepatic metastasis,local recurrence、peritioneal seeding,pathological type,type of lymph node clearance and TNM stage. Confclusions Lymphatic invasion is the most important independent prognostic factor of patients with colonic carcinoma treated surgically.
ABSTRACT
Objective To examine HOXA11,ER and PR expression in human endometrial hyperplasia and adenocarcinoma.Methods The immunohistochemistry was applied to analyze the level of HOXA11、ER and PR expression in the proliferative endometria,simple hyperplasia and endometrial adenocarcinoma.Results The expression level of HOXA11 in the endometrial hyperplasia and adenocarcinoma was significantly higher than that of proliferative endometrium(P
