The precise utility of PET scanning for bladder and prostate cancer is not yet well known. We examined the trends in PET scan utilization for imaging prostate and bladder cancer using the most recent available data from a large population based dataset. METHODS We analyzed all individuals who were identified with a diagnosis of bladder and prostate cancer from the SEER-Medicare dataset years 2004-2007 with follow-up to 2009. We eliminated all individuals with a previous or subsequent diagnosis of other cancers to ensure that the PET scan was only being associated with the cancers of interest. Chi-square and trend tests were performed as well as a logistic regression analysis to determine the predictors of PET scanning being performed. Separate models were run for each of the cancer diagnoses. All analyses were performed using SAS 9.3 and p values <0.05 were considered significant. RESULTS We identified 14,029 patients and 47,310 patients with a diagnosis of bladder cancer and prostate cancer respectively. PET scans had been performed in 372(2.65%) of bladder cancer patients and 462 (0.98%) of prostate cancer patients. PET scans were more frequently performed in more recent years, younger patients and those of higher stage and grade for both bladder and prostate cancers. Women with bladder cancer and men with prostate cancer living in the West SEER region were more likely to have PET scanning performed. PET scanning utilization had increased for both cancer types, but the increase was more substantial for bladder cancer (1.34% to 3.42%, p <.0001) compared to prostate cancer (0.76% to 1.1%, p=0.02). On regression analysis, a more recent year of diagnosis, younger age, high income, high stage or high/undifferentiated grade were predictors of PET scan utilization for patients with bladder cancer. The same factors predicted PET scan utilization in prostate cancer patients in addition to higher D'Amico risk group, higher education level and West geographic region. CONCLUSIONS The utilization of PET scanning for bladder and prostate cancer is increasing but still very selective. Utilization is limited to those with advanced stage disease or high/undifferentiated grade. The selective utilization may be driven by a combination of reimbursement constraints and careful identification of appropriate medical indication. © 2013 by American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetails Volume 189Issue 4SApril 2013Page: e902-e903 Advertisement Copyright & Permissions© 2013 by American Urological Association Education and Research, Inc.MetricsAuthor Information Oluwakayode Adejoro Minneapolis, MN More articles by this author Badrinath Konety Minneapolis, Macedonia More articles by this author Expand All Advertisement Advertisement PDF DownloadLoading ...
