ABSTRACT
ObjectiveTo study the expression level of HER-2 gene in the same pathological stage gastric cancer,and discuss the feasibility of HER-2 gene being the prognostic indicator.MethodsThe expression of HER-2 in gastric cancer was detected by immunohistocehmical technique and analyzed in relation with the pathological stage and prognosis of the patients.ResultsThe total positive rate of HER-2 in gastric cancer was 33.64％ (37/110).In stage Ⅱ,the weakly and strongly positive rates of gastric cancer were 21.31％ ( 13/61 ) and 9.84％ (6/61).In stage Ⅲ,the weakly and strongly positive rates of gastric cancer were 20.41％ (10/49) and 16.33％ (8/49).In the same pathological stage,the survival rate of patients with negative HER-2 expression was higher than weakly positive ones.And the survival rate of patients with strongly positive HER-2 expression was the lowest.The difference had statistical significance (P ＜ 0.01).ConclusionThe prognosis of patients in the same stage was correlated with the expression level of HER-2,which can be used to evaluate the biological behavior and prognosis of gastric cancer.
ABSTRACT
Objective To investigate the feasibility of application of anterograde tubular ileal fistula in Ⅰ stage anastomosis of colon cancer with acute obstruction. Method Eighty patients of colon cancer with acute obstruction who treated with anterograde tubular ileal fistula in Ⅰ stage anastomosis were analyzed restropectively. Result Clinical observation showed that 80 patients were cured and discharged,no one did occur anastomotic leakage, abdominal abscess,and other serious complications. Conclusion If correctly graspe the timing of operation for colon cancer with acute obstruction,irrigation methods,good perioperative management,select the anterograde tubular ileal fistula, Ⅰ stage resection and anastomosis is safe and feasible.
