Our results suggest that depletion of circulating B cells with rituximab does not increase the response rate, alter the toxicity profile or change the biological activity in response to low-dose IL-2 in patients with RCC or melanoma.
The recommended dose of GTI-2040 given on this infusion schedule is 185 mg/m(2)/day. GTI-2040 appears to have a manageable toxicity profile and is generally well tolerated as a single agent.
The independent prognostic factors affecting survival were assessed in 240 men undergoing treatment for metastatic prostate cancer as part of a randomized clinical trial comparing the gonadotropin releasing hormone analogue Zoladex (goserelin acetate implant) with castration. In a multivariate analysis, the most highly significant predictors were the presence or absence of bone pain, serum testosterone levels, serum alkaline phosphatase levels, and performance status. Patients with all four factors favorable for survival had a 2-year survival rate of 84% as compared with only 8% for patients with none of the four factors favorable for survival. No other factors were significant. A separate analysis of serum testosterone levels revealed that the higher the pretreatment serum testosterone level, the greater the survival rate. Compared with patients with serum testosterone levels less than 6.9 nmol/L, significant differences in survival were observed for patients with serum testosterone levels of 10.4 to 13.9, 13.9 to 17.3, and over 17.3 nmol/L. These results have important implications for the design and analysis of future clinical trials of hormone therapy and for counseling patients regarding the short-term prognosis of their disease.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
