APCCC 2019: Wishes in Locally Advanced Prostate Cancer

Basel, Switzerland (UroToday.com) Dr. Alberto Briganti presented his wishes for the future treatment of locally advanced prostate cancer. Dr. Briganti mentioned 4 major points where he would like to see progress. The first issue was the intensification of tailored multi-modal approaches. In the past, neoadjuvant androgen deprivation therapy (ADT) prior to surgery had proved to be non-beneficial. However, with the novel androgen receptors antagonists, Dr. Briganti believes we could retry this strategy. In fact, there have been several phase II trials assessing the role of enzalutamide, abiraterone, docetaxel, and LHRH agonists before surgery. Unfortunately, these were only phase II trials with a limited number of patients and the pathological/imaging endpoints that were used in these studies still need to be correlated with clinical outcomes. In any case, there are currently many ongoing trials assessing novel molecules in the neoadjuvant setting (Table 1). These include the assessment of the role of novel immunotherapy medications such as the anti-PD-L1 pembrolizumab.

Table 1 – Ongoing trials assessing novel molecules in the neoadjuvant setting:


Another option to pursue is the use of various genomic tests such as the DECIPHER test to select ideal candidates for postoperative radiotherapy. The DECIPHER test is an independent predictor of metastases after adjusting for other variables.1 Aside from pathological stage T3b/T4, Gleason scores above 8, and lymph node invasion, a Decipher score of above 0.6 has been shown to predict recurrence.2 There are also several ongoing trials assessing genomic-driven adjuvant therapies, such as the PRO-IMPACT trial evaluating the clinical utility of Decipher for the administration of postoperative therapies (NCT02080689).

There is also an ADT response signature (ADT-RS). It has been created from gene expression patterns that may serve as an early marker of androgen resistance. Patients with a low ADT-RS had similar 10-year metastasis rate in those treated with ADT compared to those not treated with ADT. In contrast, those with a high ADT-RS, treatment with ADT conferred significantly lower 10-year metastasis rate than those not treated with ADT (9.4% vs. 29.2%, p=0.02).3

The second issue discussed was image-guided surgery. Despite its increasing use and enhanced accuracy, the PET-PSMA has a sensitivity of 24.4% per node, and 38.2% per patient, which is quite low.4 Therefore, PET-PSMA will not be able to replace an anatomically defined extended pelvic lymph node dissection. Incorporation of the PET-PSMA imaging during surgery, creating a radio-guided surgery, will enhance our accuracy and allow us to remove all involved lymph nodes (Figure 1).

The third issue discussed by Dr. Briganti was the use of novel tools to improve local control. These include three-dimensional elastic augmented-reality robotic radical prostatectomy using hyper-accuracy three-dimensional reconstruction technology. This is a novel system used to identify capsular involvement when performing nerve-sparing surgery. This allows incorporating the MRI images into the robotic console during surgery and enhancing accuracy during surgery (Figure 2).

The fourth and last point was centralization of care. A large population-based study has shown that the overall survival of radical prostatectomy surgeries improved in direct correlation to the facility volume.5 Therefore, surgeries of high-risk patients should be performed strictly in high-volume centers.

Dr. Briganti concluded his talk mentioning the currently ongoing SPCG-15 trial which will randomize patients with high-risk prostate cancer to surgery + extended pelvic lymph node dissection + adjuvant radiotherapy with 2 years of bicalutamide, and to radiotherapy + ADT for 18 months (Figure 3).
