Abstract We evaluated the contribution of tumor volume (TV) to localized prostate cancer (PCa) patients’ prognosis. We retrospectively analyzed the data of 2,394 patients who underwent radical prostatectomy (RP) for localized PCa. The effect of TV volume on prostate cancer patients' prognosis was analyzed through Kaplan-Meier and Cox-proportional analysis. The mean prostate volume for all patients was 36.5 ± 15.4 cc, and the mean TV was 5.9 ± 8.3 cc. A significant positive relationship was observed between the classification by risk group in D’ Amico risk classification and the National Comprehensive Cancer Network risk group. (P < 0.001). The high TV showed significantly worse pathologic outcomes than the low TV in terms of high rates of extra-capsular extension, seminal vesicle invasion, and positive surgical margin (P < 0.05). The patients with high TV had significantly shorter biochemical recurrence-free survivals than those with low TV (P < 0.001). Finally, based on multivariate Cox-proportional analyses, TV was revealed to be an independent predictor of postoperative biochemical recurrence as both categorical (hazard ratio [HR]: 1.42, 95% confidence interval [CI]: 1.13–1.78, P = 0.003] and continuous variables (HR: 1.04, 95% CI: 1.04–1.05, P < 0.001). TV was revealed to be an independent prognostic factor in the postoperative biochemical recurrence. Patients with a high number of positive core and longer tumor length were significantly related to higher TV.

Introduction: We sought to determine predictors for early and late biochemical recurrence following radical prostatectomy among localized prostate cancer patients.Methods: The study included localized prostate cancer patients treated with radical prostatectomy (RP) at the University of Southern California from 1988 to 2008. Competing risks regression models were used to determine risk factors associated with earlier or late biochemical recurrence, defined using the median time to biochemical recurrence in this population (2.9 years after radical prostatectomy).Results: The cohort for this study included 2262 localized prostate cancer (pT2-3N0M0) patients who did not receive neoadjuvant or adjuvant therapies. Of these patients, 188 experienced biochemical recurrence and a subset continued to clinical recurrence, either within (n=19, 10%) or following (n=13, 7%) 2.9 years after RP. Multivariable stepwise competing risks analysis showed Gleason score ≥7, positive surgical margin status, and ≥pT3a stage to be associated with biochemical recurrence within 2.9 years following surgery. Predictors of biochemical recurrence after 2.9 years were Gleason score 7 (4+3), preoperative prostate-specific antigen (PSA) level, and ≥pT3a stage.Conclusions: Higher stage was associated with biochemical recurrence at any time following radical prostatectomy. Particular attention may need to be made to patients with stage ≥pT3a, higher preoperative PSA, and Gleason 7 prostate cancer with primary high-grade patterns when considering longer followup after RP.

e16162 Background: Outcomes in hospital based medicine are associated with the experience and availability of the medical staff, as mortality and morbidity rates increase each summer with new medical graduates. Hospital staff members are thought to be more fatigued and less available towards the end of the week and on weekends. However it is not known if there is a difference of outcomes based on the season or day of the week. We sought to identify if different seasons or surgical days of the week can predict poor outcomes and biochemical recurrence (BCR) in radical prostatectomy (RP). Methods: A retrospective analysis of the Columbia Urologic Oncology database was performed. 1865 consecutive men underwent RP from 1991 to 2008 by three surgeons. Data was collected in an institutional review board approved registry, with median follow up of 36 months. BCR was defined as two consecutive PSA levels > 0.2 ng/ml. Stratified cox regression methods were used to model the relationship between surgeon, preoperative variables, season, day of the week, and BCR. Winter was defined as December through February, spring as March through May, summer as June through August, and fall as September through November. Results: The mean age of the men undergoing RP was 61.2 years (37–79), with a mean preoperative PSA of 8.12. 424 men (22.7%) had positive surgical margins, and the mean estimated blood loss (EBL) was 1119cc. Patient age (p=0.68), preoperative PSA (p=0.32), EBL (p=0.51), and positive surgical margin rate (p=0.78) were not significantly different between each day. Men undergoing RP did not have different rates of BCR according to the day of the operation (p=0.58) or season (p=0.997). The particular season and day of the operation were not significantly associated with BCR, and were not independent predictors of BCR in a multivariable model after adjusting for preoperative PSA, Gleason sum, tumor stage, and surgeon. Conclusions: Patient surgical outcomes and BCR rates after RP are not associated with the particular season or day of the week of the procedure. These findings suggest that men undergoing RP do not need to be concerned about the particular season or day when scheduling the procedure. No significant financial relationships to disclose.

Context.— Seminal vesicle invasion (SVI) by prostate cancer (pT3b disease) has been considered as a key prognostic factor. Objective.— To assess the clinical impact of T3a lesions (ie, extraprostatic extension other than bladder neck invasion [BNI] or SVI [EPE], microscopic bladder neck invasion [mBNI]) in pT3b disease. Design.— We compared radical prostatectomy findings and long-term oncologic outcomes in 248 patients with pT3b disease, with versus without EPE/mBNI. Results.— Extraprostatic extension/mBNI was found in 219 (88.3%)/48 (19.4%) cases, respectively. Extraprostatic extension was significantly associated with higher preoperative prostate-specific antigen (PSA) level, higher rates of positive surgical margin (pSM) and lymphovascular invasion (LVI), and larger tumor volume. Similarly, mBNI was significantly associated with higher PSA level, higher rates of Grade Group(s) 4-5 or 5, pSM, LVI, and pN1, and larger tumor volume. Significant differences in all of these clinicopathologic features (except lymph node metastasis) between EPE−/mBNI+ or EPE+/mBNI− and EPE+/mBNI+ cases were also observed. Outcome analysis revealed that patients with EPE (P &lt; .001) or mBNI (P &lt; .001) had a significantly higher risk of disease progression than respective controls. Notably, there were significant differences in progression-free survival between EPE−/mBNI+ or EPE+/mBNI− cases and EPE−/mBNI− (P = .001) or EPE+/mBNI+ (P &lt; .001) cases. In multivariate analysis, EPE (hazard ratio [HR] = 6.53, P = .009) and mBNI (HR = 2.33, P = .003), as well as EPE−/mBNI+ or EPE+/mBNI− (HR = 11.7, P = .01) and EPE+/mBNI+ (HR = 25.9, P = .002) (versus EPE−/mBNI−), showed significance for progression. Conclusions.— From these significant findings, we propose a novel pT3b subclassification: pT3b1 (SVI alone without EPE or mBNI), pT3b2 (SVI with either EPE or mBNI), and pT3b3 (SVI with both EPE and mBNI).

Aim. To study the role of postoperative parameters in predicting the probability of development of biochemical recurrence in patients with prostate cancer with low pre-operative risk of its progression. Methods. 95 patients who underwent radical prostatectomy, were included in the study, the average age being 59.5±0.7 (44-76) years. The average levels of total and free prostate-specific antigen were 5.8±0.2 (1.71-9.9) and 1.03±0.07 (0.2-3.6) ng/ml respectively. Biochemical recurrence was defined as the level of prostate-specific antigen higher than 0.2 ng/ml after radical prostatectomy. Results. 8 (8.4%) patients during the follow-up period were diagnosed with biochemical recurrence. The average period to biochemical recurrence development was 45.8±6.7 (24-84) months. Pathomorphological examination revealed presence of tumor cells at surgical margin in 18 (18.9%) cases. Biochemical recurrence was diagnosed in 5 out of 77 (6.5%) patients with negative surgical margins and in 3 out of 18 (1.7%) patients with positive surgical margins. In our study, no correlation between the state of surgical margin and biochemical recurrence development was revealed (χ2=1.958; р=0.162). In the study group postoperative Gleason score was not prognostically significant as well (р=0.294). The average tumor volume in resected material was 11.8±1.0% (1-55%) of prostate volume (мм3). Extraprostatic extension was diagnosed in 10 (10.5%) cases. Results of univariate dispersion analysis of postoperative parameters revealed prognostic significance of tumor volume in removed specimen (р=0.007) and extracapsular extension (р=0.027). Conclusion. In our study we determined that tumor volume and extracapsular extention are independent risk factors for biochemical recurrence in prostate cancer patients with low pre-operative risk of disease progression.

Context.— Grading small foci of prostate cancer on a needle biopsy is often difficult, yet the clinical significance of accurate grading remains uncertain. Objective.— To assess if grading of limited adenocarcinoma on prostate biopsy specimen is critical. Design.— We studied 295 consecutive patients undergoing extended-sextant biopsy with only 1-core involvement of adenocarcinoma, followed by radical prostatectomy. Results.— The linear tumor lengths on these biopsy specimens were: less than 1 mm (n = 114); 1 mm or more or less than 2 mm (n = 82); 2 mm or more or less than 3 mm (n = 35); and 3 mm or more (n = 64). Longer length was strongly associated with higher Grade Group (GG) on biopsy or prostatectomy specimen, higher risk of extraprostatic extension/seminal vesicle invasion and positive surgical margin, and larger estimated tumor volume. When cases were compared based on biopsy specimen GG, higher grade was strongly associated with higher prostatectomy specimen GG, higher incidence of pT3/pT3b disease, and larger tumor volume. Outcome analysis further showed significantly higher risks for biochemical recurrence after radical prostatectomy in patients with 1 mm or more, 2 mm or more, 3 mm or more, GG2-4, GG3-4, GG4, less than 1 mm/GG2-4, less than 1 mm/GG3-4, less than 2 mm/GG3-4, 3 mm or more/GG2-4, or 3 mm or more/GG3-4 tumor on biopsy specimens, compared with respective control subgroups. In particular, 3 mm or more, GG3, and GG4 on biopsy specimens showed significance as independent prognosticators by multivariate analysis. Meanwhile, there were no significant differences in the rate of upgrading or downgrading after radical prostatectomy among those subgrouped by biopsy specimen tumor length (eg, &lt;1 mm [44.7%] versus ≥1/&lt;2 mm [41.5%] versus ≥2/&lt;3 mm [45.7%] versus ≥3 mm [46.9%]). Conclusions.— These results indicate that pathologists still need to make maximum efforts to grade relatively small prostate cancer on biopsy specimens.
