San Diego, CA, May 7, 2013- Statin use is associated with a reduced risk of progression following surgery for renal cell carcinoma (RCC), according to a new study at the 108th Annual Scientific Meeting of the American Urological Association (AUA). The study will be presented to reporters during a special press conference at the San Diego Convention Center, San Diego, CA on Tuesday, May 7 at 9:30 a.m.
Statins are cholesterol-lowering agents with anti-inflammatory and apoptotic (cell self-destruction) properties, and previous research has demonstrated they may lower the risk of developing some cancers. Given the incidence of RCC is increasing and statins are showing a favorable effect on cancer risk, researchers sought to evaluate the impact statin use may have on survival following surgery for RCC.
Researchers performed a retrospective cohort study of more than 900 patients who underwent a radical or partial nephrectomy for RCC between 1995 and 2010.
Median follow-up of the entire cohort was 42.9 months with results indicating an association between statin use and improved overall (OS) and disease-specific survival (DSS). Specific results include:
- For statin users, the three-year DSS was 90 percent (95 percent confidence interval, 86-93 percent) while the DSS for non-statin users was 83 percent (95 percent confidence interval, 80-86 percent)
- After controlling for other factors, the use of statins remained independently associated with both improved OS (hazard ratio 0.60, 95 percent confidence interval 0.42-0.86; p=0.005) and DSS (hazard ratio 0.48, 95 percent confidence interval 0.28-0.81; p=0.007)
“This retrospective study suggests those taking statins may have a higher survival rate following surgery for RCC,” said Scott Eggener, MD, Associate Professor, Urologic Oncology, University of Chicago. “Given that one in four Americans over 45 years of age take a statin and RCC occurs most often in men ages 50 – 70, it may be prudent to prospectively evaluate if statins protect against progression after RCC treatment.”
