Compared with their nondiabetic counterparts , cancer patients with preexisting diabetes are ∼50 % more likely to die after surgery .
OBJECTIVE Diabetes appears to increase risk for some cancers , but the association between preexisting diabetes and  postoperative mortality in cancer patients is less clear .
Our objective was to systematic ally review postoperative mortality in cancer patients with and without preexisting diabetes and summarize results using meta- analysis .
Morbidity and mortality after radical gastrectomy for patients with carcinoma of the stomach.
BACKGROUND This study sought to analyze the morbidity and mortality rates after  radical gastrectomy for carcinoma , since the operation has been criticized as too morbid for the benefits it may provide . STUDY DESIGN A prospect i ve study of 474 patients who underwent radical gastrectomy  was conducted . RESULTS The overall morbidity and mortality rates were 20.1 and 3.0 percent , respectively . The morbidity and mortality rates fell significantly from 27.0 to 15.7 percent ( p = 0.003 ) and 5.5 to 1.1 percent ( p < 0.001 ) , respectively , after the first 200 cases . By logistic regression analysis , it was found that male gender , combined organ(s ) resection , extended lymphadenectomy , respiratory system disease , and tumor location were significantly related to postoperative morbidity . In regard to the extent of lymphadenectomy , relative to R2 resection ( n = 102 ) , the odds ratio for morbidity after R3 resection ( n = 217 ) was 2.13 , and for R4 resection ( n = 155 ) it was 3.12 . Age older than 65 years , total gastrectomy , combined organ(s ) resection , and respiratory system disease were factors that negatively affected operative mortality . CONCLUSIONS These observations suggested that radical gastrectomy can be performed with an acceptable risk of morbidity and mortality in a general hospital
