Objective To explore prognostic factors associated with early and late recurrences after surgery for patients with gastric adenocarcinoma.Methods 214 patients who underwent curative resection for gastric adenocarcinoma were divided into 2 groups according to recurrence time:an early recurrence group included 143 patients who died within 2 years after surgery,and a late reeurrence group included 71 patients who died more than 2 years after surgery.Indexes such as age,sex,tumor site,tumor size,tumor pathology classification,Borrmann type,TNM staging,lymph node metastasis,operation type and postoperative adjuvant chemotherapy were compared.Results Single factor analysis showed that the tumor diameter,Borrmann type,TNM staging,lymph node metastasis,operation type,adjuvant chemotherapy were asoceiated with postoperative recurrence( test value were 8.32,16.21,24.90,5.22,17.23 and 3.61,respectively;all P ＜ 0.05 ).Multifactor analysis showed that tumor diameter and TNM staging is recurrent independent factors( relative risk were 5.642 and 6.211,respectively ;all P ＜ 0.05 ).Conclusion Tumor size and TNM staging are the most important factors for predicting the timing of recurrence after curative resection for gastric adenocarcinoma.Clinical practice should pay attention to follow up for patients with tumor diameter≥5cm,TNM Ⅲ-Ⅳ stage,especially within two years.

Objective To investigate the expression and clinical significance of BRMS1 ( breast cancer metastasis suppressorl ) protein in colon cancer.Methods The expression of BRMS1 protein was detected by using EliVision immunohistochemical techniques in 46 cases of colon cancer,and adjacent non cancerous colon tissues.The clinical significance with histopathologic records was aralyzed.Results The expression levels of BRMS1 ( 34.8％ ) in the colon cancer tissues was significantly lower than those of adjacent non cancerous colon tissues( x2 =23.92,P ＜0.01 ).The expression of BRMSl was significantly correlated with tumor size,clinical stage,and lymph node status (x2 =6.02,4.28,4.35,all P＜0.01) ;BRMS1 had no correlation with age,pathological type.Conclusion BRMS1 might synergistically promote the metastasis of colon cancer.Detection of the expression of BRMS1 may be hdpful in determineing the prognosis of colon cancer.
