110 Background: Clinical stage T2c (cT2c) is an indeterminate factor in the algorithm for prostate cancer (CaP) risk stratification. According to the D’Amico risk stratification and the American Urological Association (AUA) guidelines, cT2c is high−risk, whereas the National Comprehensive Cancer Network (NCCN) and EUA classify cT2c as intermediate−risk. Since determining whether cT2c is intermediate- or high-risk has implications for treatment, it is important to define what exact risk cT2c portends. Thus, we sought to assess whether cT2c tumors, without associated other high−risk factors (cT2c not otherwise specified (cT2c−nos)), behave as intermediate− or high−risk by analyzing biochemical recurrence (BCR) after radical prostatectomy (RP). Methods: We retrospectively analyzed 2,759 men who underwent RP from 1988 to 2011 from the Shared Equal Access Regional Cancer Hospital (SEARCH) database. Comparisons in time to BCR between cT2c−nos patients and intermediate−risk (prostate-specific antigen [PSA] 10 to 20 ng/ml or Gleason sum (GS) =7 or cT2b), and high−risk (PSA greater than 20 ng/ml, GS 8 to 10, cT3) patients was performed using log−rank test and Cox proportional hazards analyses. Given changes in CaP, we adjusted for year of surgery (continuous) and to adjust for case mix among centers contributing to SEARCH we included a categorical term for center. Results: A total of 99 men (4%) were classified as cT2c−nos. During a median follow-up of 66 months (IQR: 34−101 months), cT2c−nos patients had similar BCR risk as intermediate-risk (p=0.27), but significantly lower BCR risk versus high-risk patients (p<0.001, Figure). After adjusting for year and center and compared to low-risk disease, the HRs for cT2c−nos patients was similar to those with intermediate-risk (HR 1.90 vs. 2.28). When specifically compared to intermediate-and high-risk patients, and after adjusting for year and center, cT2c−nos patients had outcomes comparable to intermediate−risk (p=0.44), but significantly better than high-risk patients (HR 0.55; 95%CI 0.38,0.78; p=0.001). Conclusions: BCR risk for patients with clinical stage T2c was comparable to men who had intermediate-risk disease and significantly better than men with high-risk CaP. These findings suggest men with cT2c disease should be offered treatment options for intermediate-risk CaP.

218 Background: Molecular assays are used to improve risk stratification in prostate cancer. This study determined how the 17-gene Genomic Prostate Score (GPS) assay guides treatment decisions in patients with NCCN favorable intermediate-risk prostate cancer. Methods: This retrospective study included 324 patients from 7 urology practices in the United States. All patients had NCCN favorable intermediate-risk prostate cancer, defined as <50% positive biopsy cores and only one of the following risk factors: grade group 2 (Gleason Score 3+4), clinical stage T2b-T2c, or PSA 10-20 ng/mL. All patients also had a GPS assay report dated May 2017 to April 2019. The GPS assay allows risk stratification into post-GPS very low-, low-, favorable intermediate-, unfavorable intermediate-, and high-risk groups, with higher GPS scores representing increased risk. Data were collected from patients' charts/electronic health records. The proportion of patients who selected active surveillance (AS) over immediate definitive treatment and AS, monotherapy, or multimodal therapy was calculated with 95% confidence intervals (CI) using the Clopper-Pearson method. Results: Patients comprised 79% with Gleason Score 3+4, 19% with PSA 10-20 ng/mL, and 2% with clinical stage T2b; median GPS result was 26. Post-GPS risk groups were 0%, 16%, 11%, 57%, and 16% very low-, low-, favorable intermediate-, unfavorable intermediate-, and high-risk groups respectively. Overall, 31% (95% CI 26%, 36%) of patients selected active surveillance (AS), with rate declining as post-GPS risk increased: 57% (95% CI 42%, 71%) selected AS in the post-GPS low-risk, 51% (95% CI 34%, 69%) in the post-GPS favorable intermediate-risk, 26% (95% CI 20%, 33%) in the post-GPS unfavorable intermediate-risk, and 6% (95% CI 1%, 16%) in the post-GPS high-risk group. Post-GPS unfavorable intermediate/high risk-patients were more likely to receive monotherapy than low/favorable intermediate-risk patients (high, 72%; unfavorable intermediate, 64%; favorable intermediate, 37%; and low, 37%); high-risk patients were more likely to receive multimodal therapy (high, 23%; unfavorable intermediate, 10%; favorable intermediate, 11%; and low, 6%). Median follow-up time was 18 months, and one prostate cancer-related metastasis and 2 deaths (neither prostate cancer-related) were reported. Complications (erectile dysfunction, urinary/bowel incontinence) were more common in treated than AS patients. AS persistence was 91% (95% CI 82%, 95%) at 12 months; patients discontinued AS due to disease progression (61%) or patient preference/unknown reasons (39%). Conclusions: The GPS result is associated with selection of AS and treatment intensity in this first examination of genomic classifiers in a cohort of prostate cancer patients with NCCN favorable intermediate-risk.

123 Background: Clinical stage T2c is a nebulous factor in the algorithm for prostate cancer risk stratification. According to D’Amico risk stratification cT2c is high-risk category where NCCN guidelines place this stage in intermediate-risk. As diagnostic work up with the use of MRI continues to escalate clinical staging may become more important. As cT2c represents a possible decision fork in treatment decisions we sought to investigate which risk group the clinical behavior of cT2c tumors more closely resembles. Methods: We retrospectively analyzed data from 1089 men who underwent radical prostatectomy (RP) from 1988 to 2009 who did not have low-risk CaP from the SEARCH database. We compared time to BCR between men with cT2c disease, those with intermediate-risk (PSA 10-20 ng/ml or Gleason sum (GS) =7), and those with high-risk (PSA>20 ng/ml, GS 8-10, cT3) using Cox regression models adjusting for age, race, year of RP, center, and percent cores positive. We also compared predictive accuracy of two Cox models wherein cT2c was considered either intermediate- or high-risk by calculating concordance index c. Results: A total of 68 men (3.4%) had cT2c tumors. After a median follow-up of 47.5 months, there was no difference in BCR risk between men with intermediate-risk CaP and those with cT2c tumors (HR=0.90; p=0.60). In contrast, there was a trend for men with high-risk CaP to have nearly 50% increased BCR risk compared to men with cT2c tumors (HR=1.50; 95% CI=0.97-2.30; p=0.07) which did not reach statistical significance. Concordance index c was higher in the Cox model wherein cT2c tumors were considered intermediate-risk (c=0.6147) as opposed to high-risk (c=0.6106). Conclusions: BCR risk for patients with clinical stage T2c was more comparable to men who had intermediate-risk CaP than men with high-risk. In addition, a model which incorporates cT2c disease as intermediate-risk has better predictive accuracy. These findings suggest men with cT2c disease should be offered treatment options for men with intermediate-risk CaP. As clinical staging more routinely incorporates MRI there is the potential to better identify bilateral organ-confined CaP and further establish risk classification.

ObjectiveWe aimed compare the oncologic outcomes of radical prostatectomy (RP) with those of external beam radiotherapy (EBRT), brachytherapy (BT), or EBRT + BT (EBBT) in elderly patients with localised prostate cancer (PCa).MethodsLocalised PCa patients aged ≥70 years who underwent RP, EBRT, BT, or EBBT between 2004 and 2016 were identified from the Surveillance, Epidemiology, and End Results database. Multivariable competing risks survival analyses were used to estimate prostate cancer-specific mortality (CSM) and other-cause mortality (OCM). Subgroup analyses according to risk categories were also conducted.ResultsOverall, 14057, 37712, 8383, and 5244 patients aged ≥70 years and treated with RP, EBRT, BT, and EBBT, respectively, were identified. In low- to intermediate-risk patients, there was no significant difference in CSM risk between RP and the other three radiotherapy modalities (all P &gt; 0.05). The corresponding 10-year CSM rates for these patients were 1.2%, 2.3%, 2.0%, and 1.8%, respectively. In high-risk patients, EBRT was associated with a higher CSM than RP (P = 0.003), whereas there was no significant difference between RP and BT or RP and EBBT (all P &gt; 0.05). The 10-year CSM rates of high-risk patients in the RP, EBRT, BT, and EBBT groups were 7.5%, 10.2%, 8.3%, and 7.6%, respectively. Regarding OCM, the risk was generally lower in RP than in the other three radiotherapy modalities (all P &lt; 0.001).ConclusionsAmong men aged ≥70 years with localised PCa, EBRT, BT, and EBBT offer cancer-specific outcomes similar to those of RP for individuals with low- to intermediate-risk disease. In patients with high-risk disease, EBBT had outcomes equally favourable to those of RP, but RP is more beneficial than EBRT. More high-quality trials are warranted to confirm and expand the present findings.

Detect Prostate Cancer

Our purpose was to evaluate the relevance of repeat laterally directed sextant prostate biopsy for detection of prostate cancer in high-risk patients. Material and methods. Our study included 195 men at high risk for prostate cancer (elevated prostatespecific antigen level and/or abnormal prostate detected by digital rectal examination). We consulted the patients in outpatient department of Kaunas University of Medicine Hospital during 2003–2007. We performed transrectal ultrasound-guided laterally directed sextant prostate biopsy in every patient. For the patients with benign histological findings and increased risk of prostate cancer, laterally directed sextant biopsies were repeated. Results. Prostate cancer was detected in 30.3% of patients (59/195) on the first prostate biopsy, in 13.1% (11/84) on the second prostate biopsy, in 10.3% (4/39) on the third, and in 7.7% (1/13) on the forth biopsy. After all biopsies, prostate cancer was detected in 38.5% (75/195) of patients, and it differed significantly from the percentage of prostate cancer cases detected on the first biopsy (30.3%, P=0.04). We detected 78.7% (59/75) of all prostate cancer cases by the first laterally directed sextant prostate biopsy. The rest 21.3% (16/75) of cases we detected by repeat biopsies. The second laterally directed sextant prostate biopsy revealed additional 14.6% (n=11) of prostate cancer cases and increased the detection of prostate cancer to 93.3% (70/75). At the time of the first prostate biopsy, prostate cancer was diagnosed most frequently when patients had both risk factors: elevated prostate-specific antigen level and abnormal digital prostate examination; prostate cancer was diagnosed in 45.3% of these patients. The odds ratio to detect prostate cancer by the first biopsy in patients with elevated prostate-specific antigen level and abnormal digital prostate examination was 3.7, and odds ratio to detect prostate cancer by repeat biopsies was 4.7. Conclusions. Repeat ultrasound-guided laterally directed sextant prostate biopsies reveal more cases of prostate cancer as compared to the first prostate biopsy. The majority of prostate cancer cases (93.3%) are detected by the first and second laterally directed sextant prostate biopsies. After the first negative prostate biopsy, we recommend to repeat prostate biopsy in high-risk patients.

113 Background: Multiple definitions of high risk prostate cancer exist. Studies have primarily correlated these definitions with biochemical recurrence and not with survival. We applied six previously described high risk definitions to men treated with radical prostatectomy and evaluated their ability to predict survival outcomes in a multi-institutional cohort. Methods: The study population included 6477 men treated with radical prostatectomy between 1995 and 2005 and followed for a median of 67 months. The six high risk definitions were 1) preoperative PSA≥20ng/ml, 2) biopsy Gleason score 8-10, 3) clinical stage≥T2c, 4) clinical stage T3, 5) D’Amico definition, or 6) National Comprehensive Cancer Network definition. Survival was evaluated with the Kaplan-Meier method to generate unadjusted prostate cancer survival estimates. To control for the competing risks of age and comorbidity, multivariable Cox proportional hazard regression models were used to estimate the hazard ratio for prostate cancer specific mortality (PCSM) and overall mortality (OM) in high risk patients compared to low/intermediate risk. Results: High risk patients comprised between 0.7% (cT3) and 8.2% (D’Amico) of the study population. The 10-year Kaplan Meier prostate cancer survival estimates varied from 89.7% for PSA≥20 to 69.7% for cT3. On multivariable analysis controlling for age and comorbidity, high risk prostate cancer (of all definitions) had an increased risk of PCSM compared to low/intermediate risk with a hazard ratio (HR) ranging from 4.38 for PSA≥20 to 19.97 for cT3 (all p<0.0001). For OM, again controlling for age and comorbidity, high risk patients of all definitions except preoperative PSA≥20 (HR=0.98, p=0.99) were associated with increased risk of OM (HR range: 1.72 for D’Amico, 1.73 for stage≥T2c, 1.88 for NCCN, 2.63 for Gleason 8-10, 3.31 for cT3; all p<0.01). Conclusions: In a contemporary cohort of men with high risk prostate cancer treated with radical prostatectomy, the majority of men experienced long term prostate cancer survival. However, heterogeneity in survival outcomes existed based on the definition of high risk used. Clinical stage T3 and high Gleason score were most strongly associated with PCSM and OM.

<p><strong>Introduction:</strong> In prostate cancer, after therapy with curative intent, biochemical recurrence frequently occurs. The purpose of this study was to evaluate the impact of PET/CT with 18F-fluorocholine in restaging these patients and in their orientation, and to analyze the effect of the risk stratification, the values of PSA and the hormone suppression therapy, in the technique sensitivity. <br /><strong>Material and Methods:</strong> Retrospective analysis of 107 patients with prostate carcinoma in biochemical recurrence who underwent PET/CT with 18F-fluorocholine in our hospital, between December 2009 and May 2014. <br /><strong>Results:</strong> The overall sensitivity was 63.2% and 80.0% when PSA &gt; 2 ng/mL. It was possible to identify distant disease in 28% of the patients. The sensitivity increased from 40.0%, in patients with low and intermediate risk, to 55.2% in high-risk patients. Without hormonal suppression therapy, the sensitivity was 61.8%, while in the group under this therapy, was 67.7%. <br /><strong>Discussion:</strong> PET/CT with 18F-fluorocholine provided important information even in patients with low levels of PSA, however, with significantly increased sensitivity in patients with PSA &gt; 2 ng/mL. Sensitivity was higher in high-risk patients compared with low and intermediate risk patients, however, without a statistically significant difference. The hormone suppression therapy does not appear to influence uptake of 18F-fluorocholine in patients resistant to castration. <br /><strong>Conclusions:</strong> In this study, PET/CT with 18F-Fluorocholine showed good results in restaging patients with prostate cancer biochemical recurrence, distinguishing between loco regional and systemic disease, information with important consequences in defining the therapeutic strategy.</p>

IntroductionAllogeneic stem cell transplantation survivors are at a relevant risk of developing chronic GvHD (cGvHD), which importantly affects quality of life and increases morbidity and mortality. Early identification of patients at risk of cGvHD-related morbidity could represent a relevant tool to tailor preventive strategies. The aim of this study was to evaluate the prognostic power of immune reconstitution (IR) at cGvHD onset through an IR-based score.MethodsWe analyzed data from 411 adult patients consecutively transplanted between January 2011 and December 2016 at our Institution: 151 patients developed cGvHD (median follow-up 4 years). A first set of 111 consecutive patients with cGvHD entered the test cohort while an additional consecutive 40 patients represented the validation cohort. A Cox multivariate model for OS (overall survival) in patients with cGvHD of any severity allowed the identification of six variables independently predicting OS and TRM (transplant-related mortality). A formula for a prognostic risk index using the β coefficients derived from the model was designed. Each patient was assigned a score defining three groups of risk (low, intermediate, and high).ResultsOur multivariate model defined the variables independently predicting OS at cGvHD onset: CD4+ &gt;233 cells/mm3, NK &lt;115 cells/mm3, IgA &lt;0.43g/L, IgM &lt;0.45g/L, Karnofsky PS &lt;80%, platelets &lt;100x103/mm3. Low-risk patients were defined as having a score ≤3.09, intermediate-risk patients &gt;3.09 and ≤6.9, and high-risk patients &gt;6.9. By ROC analysis, we identified a cut-off of 6.310 for both TRM and overall mortality.In the training cohort, the 6-year OS and TRM from cGvHD occurrence were 85% (95% CI, 70-92) and 13% (95% CI, 5-25) for low-risk, 64% (95% CI, 44-89) and 30% (95% CI, 15-47) for intermediate-risk, 26% (95% CI, 10-47), and 42% (95% CI, 19-63) for high-risk patients (OS p&lt;0.0001; TRM p = 0.015).The validation cohort confirmed the model with a 6-year OS and TRM of 83% (95% CI, 48-96) and 8% (95% CI, 1-32) for low-risk, 78% (95% CI, 37-94) and 11% (95% CI, 1-41) for intermediate-risk, 37% (95% CI, 17-58), and 63% (95% CI, 36-81) for high-risk patients (OS p = 0.0075; TRM p = 0.0009).ConclusionsIR score at diagnosis of cGvHD predicts GvHD severity and overall survival. IR score may contribute to the risk stratification of patients. If confirmed in a larger and multicenter-based study, IR score could be adopted to identify patients at high risk and modulate cGvHD treatments accordingly in the context of clinical trial.
