Background:Colorectal cancer is one of the commonly seen malignant tumors in digestive system. Most patients with colorectal cancer were diagnosed in advanced stage and the prognosis is poor. Early diagnosis is crucial to improve the overall survival of patient. Currently,molecular markers for diagnosis of colorectal cancer has attracted more and more attention of the investigators. Aims:To investigate the expression and significance of Rab5A in colorectal cancer. Methods:Colorectal cancerous tissue and the paired para-cancer noncancerous tissue of 135 patients who underwent resection for colorectal cancer were collected. Expression of Rab5A mRNA in cancerous tissue,para-cancer noncancerous tissue,colon cancer cell lines HCT116,HT-29,LoVo and SW480 and normal colonic epithelial cell line NCM460 was determined by real-time PCR. Protein expression of Rab5A in cancerous tissue and para-cancer noncancerous tissue of 4 patients was detected by Western blotting. Protein expression of Rab5A in cancerous tissue of 110 patients was detected by immunohistochemistry. Correlations between expression of Rab5A and clinicopathological characteristics and prognosis of colorectal cancer were analyzed. Results:Expression of Rab5A mRNA in cancerous tissue was significantly higher than that in para-cancer noncancerous tissue(P=0. 003). Expression of Rab5A mRNA in colon cancer cell lines HCT116, HT-29,LoVo and SW480 was significantly higher than that in normal colonic epithelial cell line NCM460(P﹤0. 05). Protein expression of Rab5A in cancerous tissue was significantly higher than that in para-cancer noncancerous tissue. In 110 cancerous tissues,51(46. 4%)had low expression of Rab5A and 59(53. 6%)had high expression of Rab5A. Protein expression of Rab5A was significantly correlated with tumor size,serum carcinoembryonic antigen(CEA)level and TNM stage(P =0. 008;P =0. 002;P =0. 010). 3-year survival rate of patients with high Rab5A expression was significantly lower than that of patients with low Rab5A expression(52. 1% vs. 77. 5%,P ﹤0. 05). Rab5A protein expression,serum CEA level and TNM stage were correlated with the prognosis of patients with colorectal cancer( P =0.009;P =0. 006;P =0. 017)and were independent factors for prognosis(P =0. 026;P =0. 032;P=0. 014). Conclusions:Expression of Rab5A correlates with the malignant behavior of colorectal cancer and its high expression indicates a poor prognosis. Rab5A might be used as a predictor for prognosis of colorectal cancer.

Objective To investigate the feasibility and efficacy of the intensity modulated radiotherapy (IMRT) with oral S-1 for locally advanced pancreatic cancer.Methods Forty-two patients with locally advanced pancreatic cancer were selected,and the patients were divided into 2 groups by random digits table method with 21 cases each.The patients in treatment group were treated by IMRT combined with oral S-1 40 mg/m2 twice daily from day 1 to day 14 of a 21-d cycle;the patients in control group were treated by IMRT combined with 30 min intravenous infusions of gemcitabine 1 000 mg/m2 on day 1,8,21 and 29.Radiation was concurrently delivered at a dose of 50.4 Gy (1.8 Gy/d,5 times per week,28 fractions).The dose of intensity modulated radiotherapy was 1.8 Gy/time (5 times/week,50.4 Gy/28 times).The recent curative effect and untoward reaction were assessed at the end of radiotherapy after 4 weeks.Results There were no statistical differences in efficient rate and disease control rate between treatment group and control group:57.1％ (12/21) vs.47.6％ (10/21) and 85.7％ (18/21) vs.76.2％ (16/21),P ＞ 0.05.The neutropenia rate and thrombocytopenia rate in treatment were significantly lower than those in control group:23.8％ (5/21) vs.57.1％ (12/21) and 28.6％ (6/21) vs.66.7％ (14/21),and there were statistical differences (P ＜ 0.05).There were no statistical differences in the incidences of anemia,nausea,vomiting,elevated aminotransferase and fatigue (P＞ 0.05).Conclusions The IMRT with oral S-1 for locally advanced pancreatic cancer is safe and effective.It is worthy of clinical promotion.
