Abstract:
Objective To explore main risk factors of post-operative severe complications in elderly patients with gastric cancer.Methods From January 2006 to June 2011,a total of 236 elderly patients to receive gastrectomy for gastric carcinoma were retrospectively analyzed in this casecontrol study.The factors affecting post-operative severe complications were analyzed by multivariate logistic regression analysis.Results Age was younger in patients without than those with postoperative complications [(72.9±5.8) years vs.(80.6±6.7) years,t=-9.194,P=0.000].Serum levels of hemoglobin and albumin were higher in patients without than with post-operative complications [(109.94±18.72) g/L vs.(98.75±18.82) g/L,(38.37±5.52) g/L vs.(33.69± 3.35) g/L,t=4.391,7.080,both P=0.000].Operation time was shorter in patients without than with post-operative complications [(3.1 ± 1.0) hours vs.(3.6 ± 1.1) hours,t =-3.507,P =0.001)].Intraoperative blood transfusion volume was less in patients without than with post-operative complications [(2.5±4.4) L vs.(2.8±5.5) L,t=-4.901,P=0.000)].The long diameter of tumor was shorter in patients without than with post-operative complications [(4.5 ± 2.8) cm vs.(5.3± 2.7) cm,t =-2.111,P =0.036)].Logistic regression analysis revealed that chronic obstructive pulmonary disease (COPD),serum albumin level,age,operation time and blood transfusion volume were associated with postoperative severe complications.Logistic regression equation was as follow:P=1/[1+e(16.22-033X1+0.99X3-390X4-192X5-493X9)].Conclusions COPD,operation time,blood transfusion volume,serum albumin level and age are the main independent risk factors for post-operative severe complications in elderly patients with gastric cancer.
