The relative dose intensity (RDI) at 4 weeks after second-line targeted therapy induction may be a possible predictor of prognosis in patients with metastatic renal cell carcinoma treated with second-line targeted therapy, particularly in the International Metastatic Renal Cell Carcinoma Database Consortium poor-risk group and everolimus-treated subjects. Overall survival of patients with second-line RDI < 0.7 is significantly shorter than those with RDI ≥ 0.7.

Surgical site infection (SSI) surveillance was examined in gastric cancer patients who had undergone an open gastrectomy between 1997 and 2003 at Keio University Hospital in Tokyo, Japan. National Nosocomial Infections Surveillance (NNIS) reports and several studies have discussed SSI risk factors, but only open gastrectomy was analyzed by regression analysis. The purpose of this study was to examine these issues by performing a regression analysis for the prediction of SSI. SSI was defined by the surgical patient component according to the NNIS system (1999) produced by the Centers for Disease Control and Prevention. Patients undergoing an open gastrectomy were followed up and monitored for SSIs. Risk factors for SSI, after all factors were considered, were studied using single and multivariate analysis. The study enrolled 984 patients who had undergoing an open gastrectomy. Using multivariate and logistic regression analysis, the duration of the operation was identified as the only risk factor for SSI at open gastrectomy. Although numerous potential risk factors in surgical patients were examined, the duration of the operation was the only significant risk factor for SSIs after open gastrectomy.
