Impact On Treatment

6513 Background: With the rapid increase of robotic surgical systems in hospitals, it is important to understand the impact on treatment patterns for localized prostate cancer. The objective of this study is to determine whether the presence of robotic surgical systems independently influenced rates of surgery, radiation, and active surveillance for localized prostate cancer. Methods: We conducted an observational study using National Cancer Database (NCDB) state-level data, 2002-2010. Our study cohort includes patients newly diagnosed with clinical stage I-III prostate cancer from 48 states and Washington D.C. in the United States. The number of robotic systems installed in each state over time was obtained from publicly available information on-line. We characterized the state-level treatment pattern as the proportion of patients having surgery, radiation and active surveillance as their first course of treatment. Results: Between 2002 and 2010, the average number of robotic surgical systems per state increased from 2 to 26.3, while the unadjusted rate of surgery increased from 37.5% to 52.4%, radiation therapy decreased from 43.3% to 30.2%, and active surveillance increased from 7.0% to 9.3%. For every 10 additional robotic systems installed in a state, there would be a 2.5% increased rate of surgery (p<0.01), accompanied by a 1.3% (p=0.04) and 1.0% (p<0.01) decrease in the rate of radiation and active surveillance, respectively. Subgroup analyses suggest that the robotic adoption crowding out effect on radiation and active surveillance was driven primarily by men with stage I-II prostate cancer. If the adoption trajectory for robotic systems continues, the increased cost of treating localized prostate cancer in 2012 will be close to $27 million. Conclusions: During a period of rapid acquisition of robotic surgical systems, we found the number of robotic systems available at the state-level is significantly and directly associated with a higher rate of surgery for localized prostate cancer, and lower rates of radiation therapy and active surveillance.

Metastatic Burden

101 Background: A recent randomized controlled trial demonstrated that radiation therapy to the prostate improves overall survival for men with newly diagnosed metastatic prostate cancer with a low metastatic burden. Most patients in this trial had bony metastases (stage M1b). The benefit of prostate-directed radiation therapy for men with metastases limited to non-regional lymph nodes (stage M1a) is unknown. We investigated the association between prostate-directed radiation therapy and overall survival for men with M1a prostate cancer. Methods: We identified 2,079 men from the National Cancer Database who were newly diagnosed with M1a prostate adenocarcinoma from 2004 through 2014 and had data on the use of androgen deprivation therapy, chemotherapy, and radiation therapy. Median follow-up was estimated using the reverse Kaplan-Meier method. The association between radiation therapy to the prostate and overall survival was examined using multivariable Cox proportional hazards regression analysis. Results: Overall, 12.7% (264) of patients received radiation therapy to the prostate. Median follow-up was 4.6 years (95% confidence interval 4.3-4.8 years). On multivariable analysis, when accounting for the use of androgen deprivation therapy and chemotherapy, Gleason grade group, clinical tumor and nodal stage, and prostate-specific antigen level at diagnosis, the use of radiation therapy to the prostate was associated with a significant improvement in overall survival (adjusted hazard ratio 0.60, 95% confidence interval 0.49-0.74, P<0.001). Adjusted median overall survival was 3.3 years for patients who did not receive radiation therapy to the prostate compared to 5.5 years for patients who did. Conclusions: Similar to newly diagnosed M1b prostate cancer with a low metastatic burden, patients with M1a prostate cancer may also derive a significant overall survival benefit from receiving radiation therapy to the primary prostate tumor. The use of prostate-directed radiation therapy for M1a patients should be further investigated.

The Impact

Objective. As recent participants in an integrated prostate cancer (PCa) care center, we sought to evaluate whether financial investment in an intensity-modulated radiation therapy (IMRT) center resulted in an increased utilization of radiation therapy in our patients with newly diagnosed PCa. Materials & Methods. Following institutional review board approval, we retrospectively reviewed the records of all consecutive patients who were diagnosed with prostate cancer in the 12 months prior to and after investment in IMRT. Primary treatment modalities included active surveillance (AS), brachytherapy (BT), radiation therapy (XRT), radical prostatectomy (RP), and androgen deprivation therapy (ADT). Treatment data were available for all patients and were compared between the two groups. Results. A total of 344 patients with newly diagnosed PCa were evaluated over the designated time period. The pre-investment group totaled 198 patients, while 146 patients constituted the post-investment group. Among all patients evaluated, there was a similar rate in the use of XRT (20.71% versus 20.55%, ) pre- and post-investment in IMRT. Conclusions. Financial interest in IMRT by urologists does not impact overall utilization rates among patients with newly diagnosed PCa at our center.
