Robot-assisted surgery has replaced another minimally invasiveoperation as the main procedure to treat kidney cancer while sparing part of the diseased organ, and with comparableresults, according to a new research study by Henry Ford Hospitalurologists. While the study shows that robot-assisted partial nephrectomy(RAPD), available only since 2004, may also offer fewercomplications than laparoscopic partial nephrectomy (LPN), theresearchers cautioned that available data did not allow them toconsider such factors as surgical expertise and the complexity ofeach cancer . "To the best of our knowledge, this study is the first to comparecomplication rates after RAPN and LPN," says Quoc-Dien Trinh, M.D.,a Fellow at Henry Ford Hospital's Vattikuti Urology Institute andlead author of the study. The findings will be presented at the American UrologicalAssociation's Annual Meeting, May 19 to 23, in Atlanta. Partial nephrectomy or PN, involves surgically removing only thediseased part of a cancerous kidney, compared to the once-standardtreatment - radical nephrectomy or RN - in which the entire kidney,part of the ureter, the adrenal gland, and some surrounding tissueare removed. The less extreme PN became possible with improvementsin 3D scanning technology, and not only offers obvious advantagesover RN, but earlier studies found it results in an overall drop inrelated cardiovascular complications and death. In LPN, the surgeon removes the kidney tumor through a smallincision rather than a wide opening " less invasive but moretechnically challenging. The increasingly common use of surgicalrobots allows surgeons to operate with more precision in minimallyinvasive procedures. Using the Nationwide Inpatient Sample (NIS), the Henry FordHospital researchers identified 1,174 patients who underwentminimally invasive PN from October 2008 to December 2009. Of those,72.5 percent of the patients had robot-assisted surgery, while theremaining underwent LPN. The researchers found: Overall complication rates both during and after surgery wereessentially the same, as was the rate of blood transfusion andextended time in the hospital. However, "statistically significant differences" were found forindividual complications. Those undergoing RAPN had fewerneurologic, urinary, and bleeding problems. A slightly higher percentage of LPN patients were white, but therewas no difference according to gender, comorbidity (diseases ordisorders in addition to kidney cancer), insurance status, orincome level. Significantly more RAPNs were performed at non-teaching hospitals,and most of those were in the Midwest. LPNs were more common in theNortheast. "From a practical perspective, our results indicate that onaverage, similar intraoperative and postoperative outcomes,including transfusion rates, prolonged length of stay, andin-hospital mortality, are expected whether the patient undergoesRAPN or LPN," Trinh says. "But these results should be interpreted with care, because the NISis unable to account for disease characteristics. Specifically,it's not known if more complex cases, or surgery for higher stageand grade cancers, are more often performed by robotic orlaparoscopic procedures." Kidney cancer rates in the U.S. have increased in recent years, inpart because better technology and imaging techniques have alloweddoctors to find more suspicious masses in the kidney. Much of thesame technology has allowed surgeons to find and remove thosetumors. At the same time, as studies showed that PN was as effective as RNin controlling cancer while resulting in better survival rates, ithas become the standard treatment in both the U.S. and Europe.
