ABSTRACT
AIM:To study the expression and prognostic functions of phosphoglycerate kinase 1 ( PGK1) in prostate cancer. METHODS:The prostatic samples were collected from the patients with prostate cancer and benign pros-tatic hyperplasia (BPH) in TCM-Integrated Hospital of Southern Medical University from Jan 2013 to Dec 2013. The pro-tein expression of PGK1 in the prostate specimens was detected by immunohistochemical analysis and Western blot. Fur-thermore, the correlations of PGK1 expression with the clinicopathological features and prognosis of prostate cancer were al-so evaluate. RESULTS:The expression of PGK1 in the prostate specimens was significantly up-regulated compared with the BPH individuals. In addition, the expression of PGK1 was significantly correlated with the local infiltration, Gleason score, TNM grade, bone metastasis, and serum prostate-specific antigen (PSA) concentration. Finally, bone metastasis, serum PSA level and PGK1 expression were independent risk factors for prostate cancer illustrated by Cox analysis, and high expression of PGK1 was correlated with poor prognosis. CONCLUSION:PGK1 expression is an independent risk factor for prostate cancer, and it might act as a prognostic biomarker for prostate cancer.
ABSTRACT
Purpose To investigate the correlation and clinical value of HBO1 and Ki-67 expression in patients with hepatocelluar carcinoma ( HCC). Methods The expression of HBO1 and Ki-67 in 142 cases of hepatocellular carcinoma tis-sues and corresponding adjacent tissues was detected by immu-nohistochemical EnVision. The correlation of clinical pathologic characteristics and prognosis between them was analyzed. Re-sults The positive rates of HBO1 and Ki-67 in HCC were 69. 0% (98/142) and 55. 6% (79/142), respectively, which was obviously higher than that in para-carcinoma tissues (24.6%,19.7%) with statistically significance (P＜0.05). The expressions of HBO1 and Ki-67 were positively correlated. The expressions of HBO1 and Ki-67 were both related to the tumor size, degree of differentiation, TNM staging and portal thrombosis ( P ＜0. 05 ). Kaplan-Meier univariate statistical a-nalysis showed that the survival time of patients with high HBO1 and Ki-67 expression group was significantly shorter than that of the low expression group (P＜0. 05). Cox multivariate analysis showed that high expression of HBO1 and Ki-67, TNM staging and portal thrombosis were significantly correlated to the progno-sis of patients ( P ＜0. 05 ). Conclusion The expressions of HBO1 and Ki-67 are related to the development of HCC and prognosis. Combined detection of HBO1 and Ki-67 may helpful to judge the malignant degree and prognosis of HCC.
ABSTRACT
Objective The objectives of this study were to compare the clinicopathological features of different Lauren type gastric cancer,to carry out survival analysis,and to screen the prognostic factors.Methods The clinical pathologic data of gastric cancer patients who underwent surgical treatment at the Affiliated Tumor Hospital of Harbin Medical University from January 1,2007 to June 30,2007 were retrospectively analyzed.The 633 cases of gastric cancer patients were divided into intestinal type gastric cancer and diffuse type of gastric cancer groups,which were analyzed clinical and pathological characteristics and survival.Results Compared with diffuse type of gastric cancer,the proportion of intestinal type gastric cancer was slightly high(51.66% vs. 48.34%),the proportion of male was also high(2.94:1 vs.2.03:1,P=0.035).These could be more often in elderly patients age(≥60 years)(54.43% vs.35.94%,P<0.001).The prognosis of intestinal type gastric cancer was significantly better than diffuse gastric cancer(median survival time:90.9 months vs.37.33 months, P=0.014).Multivariate analysis showed that age ≥60 years old,CA199 abnormalities,larger tumors,poor differ-entiation,serosal invasion,initial lymph node metastasis,palliative surgery and non-pyloric resection were poor prognostic factors in gastric cancer.Conclusion Lauren type can be better respond to the clinicopathological fea-tures of different gastric cancer and guide to the prognosis.

ABSTRACT
Wnt signaling pathway participates in the physiological process of cell growth, differentiation, migration and apoptosis.Its abnormal activation is closely related to the tumorigenesis and progression.Wnt signa-ling is also known to regulate the process of proliferation,angiogenesis,adhesion,invasion and metastasis of tumor cells in non-small-cell lung cancer.There are a lot of members in Wnt signaling pathway and their expression levels affect the prognosis of non-small-cell lung cancer.It plays an instructive role in the individualized treat-ment of non-small-cell-lung cancer to lucubrate the relation between Wnt signaling pathway and the tumori-genesis and progression of non-small-cell lung cancer.
ABSTRACT
Purpose:To study the clinical and pathologica l features of rectal carcinoid and factors influencing the prognosis.Metho ds:Data of 43 rectal carcinoid patients were analyzed retrospectively.4 2 patients were followed up postoperatively. Primary tumors were classified by s ize and muscularis invasion respectively.Results:The 5-year su rvival rate was 100% for the patients with tumor 2cm. the 5-year survival rate was 100% for the patients without muscularis invasion, and 50% for those with muscularis invasion.Conclusions:Tumor size and muscularis invasion are important pr ognostic factors for rectal carcinold.
