75 Background: High-risk prostate cancer (PCa) is associated with greater risk of biochemical recurrence and cancer specific lethality. A multi-modal treatment is required for this group of patients, comprising surgery as part of it. However, the role of surgery as monotherapy is still under investigation. The purpose of this study is to analyze the influence of surgical margins on biochemical recurrence (BCR) among patients with high-risk prostate cancer (PCa) treated with robot assisted radical prostatectomy (RARP) since the start of our robotic program. Methods: We retrospectively analyzed our prospectively collected database of 5695 minimally invasive prostatectomies performed between 2000 and 2015. Clinical, pathological and oncological outcomes were evaluated in patients fulfilling Damico´s high risk characteristics. Primary endpoint was BCR, defined as post-operative PSA ≥ 0,2. Patients with neoadjuvant or adjuvant therapy were excluded. BCR was estimated with Kaplan-Meier curves. Cox proportional hazards regression was used to estimate variables associated with BCR. Results: We identified 199 high-risk PCa patients treated with RARP during the study period. Gleason score ≥ 8, PSA ≥ 20 and clinical stage ≥ T2c were present in 44%, 35% and 11% of the patients, respectively. The rate of positive surgical margins was 25%. With a median follow-up of 23 months (interquartile 12 – 34 months), 31% of the patients had BCR. Five-year BCR-free survival was 34,5%. Gleason score ≥ 8, PSA ≥ 20 and positive surgical margins were not predictors of BCR. A positive correlation of pathological stage ≥ T3 and BCR was found with (HR = 2.9; 95% CI = 1.2-6.9). Conclusions: The 5-years BCR-free survival was poor despite a low rate of positive surgical margins, when compared to historical series. We found that pathological stage ≥ T3 has a significant correlation with the BCR and that negative surgical margins do not assure good prognosis for high-risk patients.

15614 Background: It is not well documented on medical literature the value of time to treat prostate cancer. This study was performed to evaluate the value of treatment time with conformal radiotherapy (3DCRT) in high-risk prostate cancer patients. Methods: From October 1997 to January 2002, 116 patients with high-risk prostate cancer were submitted to 3DCRT and were analyzed retrospectively. The median age was 65 years-old. High risk patients were defined as patients with PSA > 20 ng/ml, and/or T3 clinical stage and/or Gleason score > 7, or two factors of intermediate risk (PSA >= 10 and < 20 ng/ml, T2b-T2c and Gleason score = 7). The median time from diagnosis to 3DCRT was 2.9 months (0.9–134.9). The median doses of radiation on prostate and on seminal vesicles were 81 Gy (72–82.8) and 61.2 Gy (45–77.4), respectively. The neoadjuvant and concomitant androgen suppression therapy were performed on 69 (59.5%) and 79 (68.1%) patients, respectively. Results: On median follow-up of 54.5 months (13.5–93.9), the 5-year actuarial overall survival, the 5-year actuarial biochemical progression-free survival and the 5-year actuarial distant metastases free survival were 84.3%, 64.7% and 88.6%, respectively. The 5-year actuarial distant metastases free survival for patients treated with 3DCRT less than or equal to 5 months was 92.5% versus 72.1% for patients treated with 3DCRT > 5 months (p=0.0076). The 5-year actuarial distant metastases free survival for patients with biochemichal progression was 68.8% versus 100% for patients with no biochemical progression (p 65 years-old (p=0.0160). Conclusions: The study suggests that delaying 3DCRT in high-risk prostate cancer patients lowers the actuarial distant metastases free survival. Biochemical progression may be a strong prognostic factor for distant metastases and, consequently, poor quality of life. No significant financial relationships to disclose.

Background/objectiveThere are no randomized trials on the comparative effectiveness of radical prostatectomy (RP) and radiotherapy (RT) for high-risk prostate cancer. Our aim was to compare treatment outcomes of high-risk prostate cancer after RP and RT, including overall survival (OS), biochemical-progression-free survival (bPFS) and disease-progression-free survival (dPFS), using two cancer treatments centers’ patient data.MethodsData on high-risk prostate cancer patients between 2005 and 2009 were retrospectively reviewed in two cancer centers: National Cancer Institute, Vilnius, Lithuania and N.N. Alexandrov National Cancer Centre of Belarus, Minsk, Belarus; 210 patients were included in the study group treated with RP (n = 174) or RT (n = 36). The mean follow-up time was 5.6 and 6.6 years, respectively.ResultsLower T stage was an independent predictor of better OS (p = 0.01) and bPFS (p = 0.03). Only the highest Gleason score ≥8 was significantly predictive of a worse OS (p = 0.05), bPFS (p = 0.02) and dPFS (p = 0.001). A high PSA level was predictive of a worse bPFS (p = 0.007 for PSA ≥20) and dPFS (p = 0.008 for ≥20). The treatment modality in this study was insignificant after T stage, Gleason score and PSA level adjustment for OS, bPFS survival and dPFS survival (p = 0.17, p = 0.39, p = 0.20).ConclusionsThe T stage, Gleason score and pretreatment PSA level are significant factors for OS, bPFS survival, and dPFS survival of highrisk prostate cancer patients. Treatment option (RP or RT) was not an independent predictor of survival in this study.

Aim: To evaluate the preoperative predictors of pathological lymph node (LN) metastasis and prognostic factors for postoperative biochemical recurrence (BCR) in robot-assisted radical prostatectomy with extended pelvic LN dissection in patients with D'Amico high-risk prostate cancer (PCa). Patients and Methods: Overall, 107 patients with D'Amico high-risk PCa underwent robot-assisted radical prostatectomy with extended pelvic LN dissection without neoadjuvant or adjuvant therapy. BCR was defined as a prostate-specific antigen (PSA) level ≥0.2 ng/ml. Moreover, BCR-free survival rates were determined using Kaplan-Meier analysis. Logistic regression analysis was used to evaluate preoperative predictors of pathological LN metastasis. Cox regression analysis was used to evaluate the effects of preoperative and pathologic variables on BCR. Results: The median follow-up was 21 months, and the 5-year BCR-free survival rate was 59.8%. The positive LN rate was 21.5%. In multivariate analysis, the percentage of positive cores was a significant preoperative predictor of positive LNs. Patients with >50% positive cores (p=0.004) and PSA density (PSAD) >0.5 ng/ml/cc (p=0.005) had a high risk of having ≥3 positive LNs. In multivariate analysis, PSAD >0.5% was a significant preoperative predictor of BCR. Among the postoperative predictors, the number of positive LNs was significantly associated with BCR. Patients with ≥3 positive LNs (n=7) had significantly lower BCR-free survival rates than patients with one or two positive LNs (n=16) (p<0.001). Patients with >50% positive cores and PSAD >0.5 ng/ml/cc had a risk for a high number of positive LNs (≥3) that was strongly associated with shorter BCR-free survival (p<0.001). Conclusion: The percentage of positive cores may be useful as a preoperative predictor of pathological LN metastasis in patients with high-risk PCa. Patients with >50% positive cores and PSAD >0.5 ng/ml/cc were found to have a high risk for ≥3 positive LNs and shorter BCR-free survival.

Background/objective. Predictive criteria are needed to evaluate the risk of disease progression after radical prostatectomy. Such criteria would help to select patients most likely to benefit from adjuvant or multimodality treatment. Our aim was to identify predictive factors for biochemical recurrence among the  pre- and post-operative parameters in high-risk prostate cancer patients after radical prostatectomy. Methods. Data on high-risk prostate cancer patients between 2005 and 2009 were retrospectively reviewed in two cancer centers: National Cancer Institute, Vilnius, Lithuania, and N.  N.  Alexandrov National Cancer Centre of Belarus, Minsk, Belarus. 199 patients were selected for the  study. The  pre-operative independent variables were T stage, pretreatment PSA level and Gleason score. Surgical margins and perineural invasion were additionally known for 122 patients. The outcomes measured were biochemical recurrence free and overall survival. The mean follow-up time was 5.8 years. Results. Lower T stage (p = 0.001) and pretreatment PSA (p = 0.0001) were associated with better survival. In the multivariate analysis of pre-operative factors, high T stage (p = 0.008) and pretreatment PSA (p = 0.009) were predictive of biochemical recurrence. When postoperative parameters were included in the multivariate analysis, only pretreatment PSA (p = 0.01), positive surgical margins (p = 0.003) and perineural invasion (p = 0.03) remained relevant independent predictors of biochemical recurrence. Conclusions. Pretreatment PSA, positive surgical margins and perineural invasion were independent predictors of biochemical recurrence after radical prostatectomy in high-risk prostate cancer patients, while the  T stage became insignificant after adjusting for postoperative parameters.
