Objective　To investigate the features of extracolonic carcinoma spectrum in Northeast Chinese with hereditary nonpolyposis colorectal cancer. Methods　The extracolonic carcinoma spectrum’s characteristics of 85 families registered in strict conformity with the HNPCC Amsterdam criteriaⅡwere analyzed retrospectively. Results　In the 85 HNPCC families， the tumorous patients were 509 cases，the primary tumors were 589 cases， among the total consisted of 219 cases of colon cancer， 91 cases of rectal cancer，and 279 cases of extracolonic cancer， the most common extracolonic carcinoma was lung cancer. Conclusions　Extracolonic carcinoma is an important part of cancer spectrum in HNPCC family， and the common extracolonic carcinoma in Northeast of Chinese are lung cancer， gastric cancer， endometrial cancer， liver cancer， and esophagus carcinoma.

Expression and Significance on Expressions of NKD1 and APC in Breast Carcinoma

ObjectiveTo detect the expressions of NKD1 and APC in breast carcinoma tissues and to explore the clinical significance of their existence and their correlation. MethodsThe study selected 75 patients with breast carcinoma as the observation group, and their corresponding normal breast tissues from the breast carcinoma tissues more than 5 cm as the control group. The expressions of two proteins were detected by immunohistochemistry. Their relationship with the pathological characteristics of breast carcinoma and the correlation of the two proteins were analyzed. ResultsThe positive expression rates of NKD1 and APC in normal breast tissues were significantl higher than those in breast carcinoma tissues (82.67% vs. 36.00%, 89.33% vs. 45.33%, P < 0.05). The expression of NKD1 was not correlated with the age of patients with breast carcinoma (P > 0.05), while correlated with the degree of differentiation, TNM stage, lymph node metastasis, and remote organ metastasis of breast carcinoma (P < 0.05). The expression of APC was not correlated with the age of patients with breast carcinoma, the degree of differentiation and lymph node metastasis of breast carcinoma (P > 0.05), while correlated with the TNM stage and remote organ metastasis of breast carcinoma (P < 0.05). The expressions of NKD1 and APC in breast carcinoma was positively correlated (r=0.609, P < 0.05). ConclusionNKD1 and APC may be involved in the development and remote organ metastasis of breast carcinoma, and the two proteins may have a synergistic role in breast carcinoma.

Expression of Obesity Hormone Leptin in Human Colorectal Cancer

Objective To evaluate the relationship between leptin level in serum and clinicopathologic features of colorectal cancer. Methods ABC-ELLSA was used to detect the leptin level in 30 cases of colorectal cancer without dystrophy (cancer group) and 24 normal controls (control group). The expressions of K-ras， p53， adenomatous polyposis coli （APC） gene and delete in colorectal carcinoma gene (DCC) mRNA of the tumor were examined by RT-PCR, the levels of serum CEA and CA19-9, and other clinicopathologic features were also recorded. Results The leptin level in cancer group 〔（3.53±1.72） μg/L〕 was higher than that in control group 〔（2.27±1.01） μg/L〕, P＜0.05, and the difference was independent on gender. There were no significant differences of leptin level in different tumor stages and different tumor location （Pgt;0.05）. Leptin level of poorly differentiated tumor was obviously lower than that of well differentiated and moderately differentiated tumor （P＜0.05）. There were no associations between leptin level and the levels of CEA and CA19-9, likewise there were no associations between leptin level and the expressions of K-ras, p53, APC and DCC in tumor （Pgt;0.05）. Conclusion The leptin level of colorectal cancer patient is higher than that of normal person, which is affected by the differentiation of tumor. But there are no significant correlations between the level of leptin in serum and TNM stage, tumor location, tumor markers of serum, K-ras, p53, APC or DCC in tumor.

Relationship Between βCatenin，Adenomatous Polyposis Coli Genes and Tumors

Objective To discuss the molecular structures and functions of βCatenin and APC (Adenomatous polyposis coli) genes, as well as the roles they played during the carcinogenesis and progression of tumors. MethodsAdvances in molecular biology and oncology of βCatenin and APC genes in recent years has been reviewed. ResultsHigh expression of βCatenin and APC genes was an early event during the carcinogenesis due to the abnormal regulation of βCatenin and APC genes. But on the contrary, the low expression of these two genes was probably associated with the progression of tumors. Moreover, βCatenin and APC genes could also regulate the expression of p53,cmyc genes and cyclin D1. Conclusion βCatenin and APC genes may play a key role during the carcinogenesis and progression of tumors and modulate other oncogen/suppressor gene and factors.

Relationship Between The Expressions of hMLH1 and hMSH2 Protein and Clinicopathological Features and Prognosis of Hereditary Nonpolyposis Colorectal Cancer

Objective　To investigate the relationship between the expressions of mismatch repair （MMR） genes （include hMLH1 and hMSH2） and clinicopathological features and prognosis of hereditary nonpolyposis colorectal cancer （HNPCC）. Methods　Immunohistochemistry method （Elivision-two step） was used to test expressions of hMLH1 and hMSH2 proteins （both hMLH1 and hMSH2 protein-positive delimited as MMR protein-positive） in 48 patients with HNPCCaccording to revised Bethesda guidelines， and analyzed the relationship between the expression of MMR protein and clinicopathological features and prognosis of HNPCC. Results　Loss rate of hMLH1 protein （20.83%，10/48） was signi-ficantly higher than that of hMSH2 protein （8.33%，4/48）， Ρ＜0.05， and positive expression rate of MMR protein was 70.83% （34/48）. Expression of MMR protein was related with tumor infiltration depth （Ρ＜0.05）. Survival rate of patients with expression and without expression of MMR protein was 85.29% （29/34） and 85.71% （12/14）， respectively， the survival curves of them didn’t significantly differed from each other （Ρ＞0.05）. Conclusions　Loss rate of hMLH1 protein is higher than that of hMSH2 protein. Expre ssions of hMLH1 and hMSH2 protein are related with tumor infiltration depth， but not related with prognosis.

Peutz-Jeghers综合征肠道息肉恶变的临床分析

目的探讨Peutz-Jeghers综合征肠道息肉恶变的临床诊治经验。 方法对2005～2015年期间所诊治的221例Peutz-Jeghers综合征患者中11例息肉恶变患者的临床病理资料进行回顾性分析。 结果11例PeutzJeghers综合征息肉恶变患者确诊时的中位年龄为31.36岁。行肠镜20例次，胃镜8例次，双气囊电子小肠镜19例次，胶囊内镜1例次。手术原因依次为肠梗阻、肠套叠、息肉恶变和消化道出血。癌变息肉分别位于十二指肠（4例）、小肠（4例）和结直肠（3例）。病理类型以管状腺癌（5例）和黏液腺癌（5例）最多见。本组11例患者均无手术死亡，1例术后发生腹部切口感染，经伤口换药等处置后出院。术后3例患者接受XELOX方案化疗，其余未作特殊治疗。1例术后失访，10例随访1个月至7年（中位随访期2.12年），其中4例术后1～3个月死于十二指肠癌肝肺转移、空肠腺癌肝转移和结肠癌肝肺多发转移，其余患者定期复查消化内镜或消化道造影等检查至今。 结论PeutzJeghers综合征息肉恶变患者年龄较小，早诊断、早治疗、定期复查可提高患者的检出率和临床治疗效果。
