The inheritance of mitochondrial haplogroup U is associated with an approximately 2-fold increased risk of prostate cancer and 2.5-fold increased risk of renal cancer in white North American individuals. Therefore, individuals with this mitochondrial haplotype are in a high risk group. Because mitochondrial haplogroup U is found in 9.35% of the white United States population, there are more than 20 million individuals in this high risk group.
Abstract:The prevention of venous thromboembolism is a major concern in cancer patients undergoing pelvic surgery. Radical retropubic prostatectomy is a common treatment for localized prostate cancer and has been identified as a high risk procedure for postoperative venous thromboembolism. However, most patients diagnosed with prostate cancer in the current era have clinically localized , low volume disease and the risk of venous thromboembolism is very low. Multiple guidelines exist for the prevention of venous thromboembolism in patients undergoing radical retropubic prostatectomy and pharmacological venous thromboembolism prophylaxis is recommended. Most urological surgeons in the USA however, do not routinely utilize pharmacological prophylaxis. A major concern arises when radical retropubic prostatectomy is performed with a concomitant pelvic lymphadenectomy. Pharmacological prophylaxis is known to increase the rate of lymph drainage and the rate of lymphocele formation. Evidence suggests that lymphocele may be an independent risk factor for venous thromboembolism in the postoperative period. These factors raise concern over current guidelines calling for routine use of pharmacological venous thromboembolism prophylaxis in radical retropubic prostatectomy especially when lymphadenectomy is performed simultaneously.
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.
