WASHINGTON, D.C. (May 15, 2011)With an increase in abdominal imaging over the past decade, there has been an increase in the detection of incidental kidney cancer, which has led to concerns that we may be over-treating indolent disease. As part of this effort, clinicians have started to investigate the effectiveness of active surveillance (AS), or close observation as opposed to immediate surgery, for select patients with small renal masses (SRMs). Today, Fox Chase Cancer Center researchers will announce the results of its systematic review and pooled analysis, which for the first time combined several institutions' experience with active surveillance of small renal masses. Their goal was to identify trends in radiographic tumor growth rates and progression to either treatment or metastasis, and found that in select patients, active surveillance may be a viable option when surgery is risky due to poor health or advanced age.
Marc Smaldone, M.D., urologic oncology fellow at Fox Chase and lead author on the study, will present the results at the AUA 2011 Annual Meeting on Tuesday, May 17, 2011.
"Kidney cancer is most often a surgically treated disease, so studies such as this one, which help to confirm that active surveillance with curative intent can be an effective strategy for certain patients, are crucial," says Smaldone. "Surgery has substantial consequences for many patients with competing risks such as heart or lung disease. The ability to offer a management strategy that avoids the risks of potentially unnecessary surgery is an attractive concept in contemporary cancer treatment."
To further investigate the risks of cancer progression in patients undergoing active surveillance, Fox Chase researchers combined all the available individual data published by institutions examining the observation of small renal masses. The team identified and pooled a total of 18 institutional series, of which Fox Chase's experience represent
