4670 Background: As concerns mount regarding overtreatment and over-diagnosis of prostate cancer (CaP), active surveillance (AS) is increasingly utilized in low risk patients. While African-American (AA) race is associated with adverse outcomes after prostatectomy, its effect on patients managed with AS is not known. Methods: A retrospective review identified 222 patients managed with AS at the Duke Prostate Center from January 2005 to September 2011. All men had CaP diagnosed on biopsy performed at our center, and elected AS over treatment. Failure was defined as progression to treatment. In men who failed AS, the reasons for failure, follow-up PSA and biopsy characteristics were analyzed. The primary outcome - time from diagnosis to failure of AS for a reason other than patient choice - was analyzed with univariable and multivariable Cox proportional hazards models. Results: In our AS cohort, 73% are Caucasian and 23% AA. Median follow-up is 25.4 months. Age, household income, BMI, PSA, clinical stage, family history, prostate volume, number of cores with cancer, and Gleason grade on initial biopsy did not differ by race. The number of biopsies and PSA tests performed on AS did not differ by race. A higher proportion of AA men tended to fail from biopsy progression (72.7% vs. 63.8%) while a lower proportion failed by choice (9.1% vs. 14.9%) compared to Caucasians (p = 0.114). AA men had a significantly shorter time to failure (HR 1.74, p = 0.045) compared to Caucasians. There was a trend toward increased Gleason grade 8 or higher cancer on follow-up biopsy in AA compared to Caucasian men (10% vs. 2.5%, p = 0.08). AA race remained a predictor (HR 1.76, p = 0.058) of failure on multivariable analysis, as did initial PSA (HR 1.90, p = 0.031) and number of cores with cancer on initial biopsy (HR 1.29, p = 0.013). Conclusions: AA race was associated with higher risk for failure of AS. There was a trend toward AA men failing due to biopsy progression and with higher grade cancer. Additional follow-up is necessary to determine how this affects the long term outcomes of these men.

103 Background: While three prospective trials have demonstrated benefit from adjuvant radiation (XRT) after radical prostatectomy (RP) in patients with positive surgical margins (PSM), its use varies amongst physicians. Many rely on clinical acumen to determine the optimal strategy for application of XRT post RP. We aim to determine if the length of PSM and highest Gleason grade (GG) of tumor at the PSM (hGGPSM) can be used to identify patients at greatest risk of biochemical failure (BCF) post RP. Methods: A retrospective review of all RP patients at The University of Texas MD Anderson Cancer Center from 2002 to 2010 was performed. After a single pathologist review, patients with organ confined disease (pT2), pathologic N0/Nx and a PSM were included. BCF was defined as 2 sequential PSA values of ≥0.2 or any detectable PSA prompting XRT. Patients receiving adjuvant XRT or with <12 months follow-up were excluded. Results: 205 patients met the inclusion criteria. Median PSA was 5.3 ng/mL (0.5-33) and median follow-up was 64 months (13-130). The majority were low clinical stage (cT1c: 65%), low (11%)/intermediate (82%) grade and had a single site of a PSM (90%). BCF occurred in 47 patients for a 5 yr BCF free survival (BCFFS) of 69%. PSM length was significantly associated with BCFFS (≤1mm vs >1, p=0.02). When accounting for hGGPSM, Gl 3 tumors were less likely to experience BF (5 yr BCFFS-96%) regardless of PSM length, while BCFFS for Gl >3 tumors were significantly lower dependent upon length of PSM ( ≤1mm vs >1mm, p=0.03). On multivariable analysis length of PSM (p=0.05) and hGGPSM (p=0.007) remained independent predictors of BCF (Table). Conclusions: Length of PSM and hGGPSM are independent predictors of BCF. These should be considered when evaluating patients for adjuvant XRT and in risk stratifying patients in prospective clinical trials. [Table: see text]

Purpose We assessed outcomes of men with prostate cancer enrolled in active surveillance. Patients and Methods Since 1995, a total of 769 men diagnosed with prostate cancer have been followed prospectively (median follow-up, 2.7 years; range, 0.01 to 15.0 years) on active surveillance. Enrollment criteria were for very-low-risk cancers, defined by clinical stage (T1c), prostate-specific antigen density < 0.15 ng/mL, and prostate biopsy findings (Gleason score ≤ 6, two or fewer cores with cancer, and ≤ 50% cancer involvement of any core). Curative intervention was recommended on disease reclassification on the basis of biopsy criteria. The primary outcome was survival free of intervention, and secondary outcomes were rates of disease reclassification and exit from the program. Outcomes were compared between men who did and did not meet very-low-risk criteria. Results The median survival free of intervention was 6.5 years (range, 0.0 to 15.0 years) after diagnosis, and the proportions of men remaining free of intervention after 2, 5, and 10 years of follow-up were 81%, 59%, and 41%, respectively. Overall, 255 men (33.2%) underwent intervention at a median of 2.2 years (range, 0.6 to 10.2 years) after diagnosis; 188 men (73.7%) underwent intervention on the basis of disease reclassification on biopsy. The proportions of men who underwent curative intervention (P = .026) or had biopsy reclassification (P < .001) were significantly lower in men who met enrollment criteria than in those who did not. There were no prostate cancer deaths. Conclusion For carefully selected men, active surveillance with curative intent appears to be a safe alternative to immediate intervention. Limiting surveillance to very-low-risk patients may reduce the frequency of adverse outcomes.

Abstract Objectives The PRECISE recommendations for magnetic resonance imaging (MRI) in patients on active surveillance (AS) for prostate cancer (PCa) include repeated measurement of each lesion, and attribution of a PRECISE radiological progression score for the likelihood of clinically significant change over time. We aimed to compare the PRECISE score with clinical progression in patients who are managed using an MRI-led AS protocol. Methods A total of 553 patients on AS for low- and intermediate-risk PCa (up to Gleason score 3 + 4) who had two or more MRI scans performed between December 2005 and January 2020 were included. Overall, 2161 scans were retrospectively re-reported by a dedicated radiologist to give a PI-RADS v2 score for each scan and assess the PRECISE score for each follow-up scan. Clinical progression was defined by histological progression to ≥ Gleason score 4 + 3 (Gleason Grade Group 3) and/or initiation of active treatment. Progression-free survival was assessed using Kaplan-Meier curves and log-rank test was used to assess differences between curves. Results Overall, 165/553 (30%) patients experienced the primary outcome of clinical progression (median follow-up, 74.5 months; interquartile ranges, 53–98). Of all patients, 313/553 (57%) did not show radiological progression on MRI (PRECISE 1–3), of which 296/313 (95%) had also no clinical progression. Of the remaining 240/553 patients (43%) with radiological progression on MRI (PRECISE 4–5), 146/240 (61%) experienced clinical progression (p < 0.0001). Patients with radiological progression on MRI (PRECISE 4-5) showed a trend to an increase in PSA density. Conclusions Patients without radiological progression on MRI (PRECISE 1-3) during AS had a very low likelihood of clinical progression and many could avoid routine re-biopsy. Key Points • Patients without radiological progression on MRI (PRECISE 1–3) during AS had a very low likelihood of clinical progression and many could avoid routine re-biopsy. • Clinical progression was almost always detectable in patients with radiological progression on MRI (PRECISE 4–5) during AS. • Patients with radiological progression on MRI (PRECISE 4–5) during AS showed a trend to an increase in PSA density.

Abstract Background In clinical practice, patients with IBD have their biologic therapies withdrawn due to variety of reasons. The aim of the study was to report on predictors of prognosis in IBD patients after biologics have been discontinued, with a minimum follow-up of 24 months. Methods All IBD patients who discontinued their first-use biologic were identified between January 2013 and Dec 2016 from EMR at a tertiary referral centre, to ensure at least 24 months follow-up. Reasons for discontinuation and pre-defined adverse outcomes (steroid and other rescue therapies, hospitalisations, surgery including perianal) were recorded. The data were analysed using multivariable and univariable logistic regressions within a machine learning technique in order to predict adverse outcomes, within the stated timeframe. We tested the significance of the identified predictors and performed Kaplan–Meier survival analysis to compare patients with elective vs. non-elective discontinuation of biologics. Results 147 patients who discontinued biologics (M = 74, median age 39y; CD = 110) were identified. Follow-up ranged from 24 to 60 months (median 40 months). The reasons for non-elective discontinuation included side effects (n = 21, 14%), primary or secondary non-response (n = 33, 22%) and patient choice (n = 10, 7%), among others. 59 (40%) patients had elective discontinuation. In this cohort, elective discontinuation resulted in fewer IBD-related adverse outcomes (AO) compared with non-elective. Figure 1 shows a Kaplan–Meier curve comparing the two (p = 0.003). Using data from all 147 patients, multivariable logistic regression analysis was done to identify significant predictors of prognosis. These are represented in Table 1. Overall, a significant number of patients (n = 80, 54%) had AO within 6 months of discontinuation, and 96 (65%) patients needed biologics to be restarted by the end of the study follow-up period. Conclusion Among IBD patients who discontinued biologics, there were fewer AO when they were electively discontinued. However, majority of patients required restart of biologics to manage their disease during the follow-up period. Clinicians need to be cautious when considering biologic discontinuation given the high proportion of AO and re-escalation to biologics therapy.

Introduction: We aimed to investigate whether patients on active surveillance (AS) had worse outcomes than patients who received immediate treatment with radiotherapy and whether a Gleason grade progression on repeat biopsy influenced outcome. Methods: From our institutional database, we identified 2001 patients treated between 2005 and 2019 with primary external beam radiation therapy or brachytherapy. Biochemical recurrence (BCR) was analyzed in relation to clinical factors such as a Gleason grade progression or having multiple biopsies vs. only one biopsy. Patients on AS were identified as those who had undergone ≥2 biopsies. We used log-rank tests for univariate analysis (UVA) and Cox regression analysis for multivariable analysis (MVA). Results: Of 2001 patients, 374 (19%) patients had ≥2 biopsies before treatment, of which 48% presented with a Gleason grade progression of mostly to Gleason 3+4 (36%); 32% had a cancer volume increase on biopsy and 16% had no significant change on biopsy. For patients with ≥2 biopsies, median time from first biopsy to treatment was 22.0 months (interquartile range [IQR] 14.7–36.1). By UVA, patients with Gleason grade progression (n=105) had a worse BCR-free rate (p=0.02) than patients who had no grade progression on repeat biopsy or only one biopsy. On MVA, this effect was lost. Having ≥2 biopsies was not a significant negative prognostic factor on UVA (p=0.2) or MVA. Conclusions: In our experience, radiotherapy after a period of AS, even with Gleason grade progression, did not lead to worse outcomes compared to patients who had radiotherapy after only one biopsy.

128 Background: prostate brachytherapy at our institution was analyzed for implant quality on biochemical control. Methods: We treated 368 patients with clinically localized prostate cancer. All patients underwent 1 month CT based dosimetric analysis. Follow up data was available on 289 patients with a minimum follow up of 5 years. Gleason score was 6 in 80% (n=233), and 7 in 20% (n=56). Clinical stage was T1c in 90% of cases (n=260), T2a was 8% (n=23), T2b was <1% (n=3), T2c was < 1% (n=2). The initial prostate-specific antigen was < 10 ng/ml in 95% (n=274), 10.1-20 ng/ml in 5% (15).Patients with low risk disease ( clinical stage T1c, Gleason score 6 with a PSA < 10 ng/ml) n=228. Patients with intermediate risk disease Gleason 7 adenocarcinoma or with a PSA> 10 ng/ml < 20 ng/ml )n= 61. All patients were treated with I (125). All patients underwent a 1-month CT-based dosimetric analysis. The implant dose was defined as the dose delivered to 90% of the prostate volume on post implant dosimetry (D(90)). Results: At minimum follow up of 5 years overall freedom from biochemical failure was 91.4%. For Gleason grade 6 freedom from biochemical failure was 95%. For Gleason grade 7 freedom from biochemical failure was 77%. Based on PSA freedom from biochemical failure for PSA <10 ng/ml at diagnosis was 92 % and for PSA >10 ng/ml and <20 ng/ml was 80%. In patients with low risk disease ( clinical stage T1c, Gleason 6 adenocarcinoma with a PSA < 10ng/ml) the freedom from biochemical failure was 94%. In patients with intermediate risk disease (Gleason 7 adenocarcinoma or with a PSA >10 ng/ml <20 ng/ml ) freedom from biochemical failure was 84%. Patients with optimal dose implants n=264 freedom from biochemical failure was 95%. Patients with suboptimal dose implants n=25 freedom from biochemical failure was 52% Conclusions: With a minimum follow up of 5 years our data support the use of implant alone in low risk prostate cancer patients with a freedom from biochemical failure of 94%. Our data also shows the importance of implant quality in achieving optimal out comes.

Purpose Active surveillance is now considered a viable treatment option for men with low-risk prostate cancer. However, little is known regarding changes in Gleason grade on serial biopsies over an extended period of time. Patients and Methods Men diagnosed with prostate cancer between 1998 and 2009 who elected active surveillance as initial treatment, with 6 or more months of follow-up and a minimum of six cores at biopsy, were included in analysis. Upgrading and downgrading were defined as an increase or decrease in primary or secondary Gleason score. Means and frequency tables were used to describe patient characteristics, and treatment-free survival rates were determined by life-table product limit estimates. Results Three hundred seventy-seven men met inclusion criteria. Mean age at diagnosis was 61.9 years. Fifty-three percent of men had prostate-specific antigen of 6 ng/mL or less, and 94% had Gleason score of 6 or less. A majority of men were cT1 (62%), had less than 33% of biopsy cores involved (80%), and were low risk (77%) at diagnosis. Median number of cores taken at diagnostic biopsy was 13, mean time to follow-up was 18.5 months, and 29% of men had three or more repeat biopsies. Overall, 34% (129 men) were found to have an increase in Gleason grade. The majority of men who experienced an upgrade (81%) did so by their second repeat biopsy. Conclusion A proportion of men experience an upgrade in Gleason score while undergoing active surveillance. Men who experience early upgrading likely represent initial sampling error, whereas later upgrading may reflect tumor dedifferentiation.

Background and objectives: Membranoproliferative Glomerulonephritis (MPGN) and C3 Glomerulopathy are rare and overlapping disorders associated with dysregulation of the alternative complement pathway. Specific aetiological data for paediatric MPGN/C3 glomerulopathy are lacking, and outcome data are based upon retrospective studies without aetiological data. Design, setting, participants, and measurements: Eighty prevalent pediatric patients with MPGN/C3 glomerulopathy underwent detailed phenotyping and long-term follow-up within the National Registry of Rare Kidney Diseases (RaDaR). Risk factors for kidney survival were determined using COX proportional hazards model. Kidney and transplant graft survival was determined using Kaplan-Meier method. Results: Central histology review determined 39 C3 glomerulopathy, 31 immune-complex MPGN and 10 immune-complex glomerulonephritis (GN) cases. Patients were aged 2-15 (median 9 (IQR 7-11) years. Median complement C3 and C4 levels were 0.31g/L and 0.14g/L respectively; acquired (anti-complement autoantibodies) or genetic alternative pathway abnormalities were detected in 46% and 9% patients respectively, across all groups including immune-complex GN. Median follow-up was 5.18 (IQR 2.13-8.08) years. Eleven patients (14%) progressed to kidney failure with 9 transplants performed in 8 patients, 2 of which failed due to recurrent disease. Presence of >50% crescents on initial biopsy was the sole variable associated with kidney failure in multivariable analysis (Hazard Ratio 6.2, p = 0.045; 95% CI 1.05 to 36.6). Three distinct C3 glomerulopathy prognostic groups were identified according to presenting eGFR and >50% crescents on initial biopsy. Conclusions: Crescentic disease was a key risk factor associated with kidney failure in a national cohort of pediatric MPGN/C3 glomerulopathy and immune-complex GN. Presenting eGFR and crescentic disease help define prognostic groups in pediatric C3 glomerulopathy. Acquired abnormalities of the alternative pathway were commonly identified but not a risk factor for kidney failure.

Management of prostate cancer remains controversial, in large part because of its wide heterogeneity in terms of aggressiveness and prognosis. Early detection efforts based on prostate specific antigen (PSA) and aggressive treatment of high-risk cancers have yielded major improvements in mortality rates, but overtreatment of low-risk cancers—those unlikely to cause symptoms or threaten life if they were never detected—is associated with high rates of avoidable toxicity and cost. Prostate cancer can be effectively risk-stratified based on tools (e.g. nomograms, CAPRA score) integrating the PSA level, Gleason grade, clinical stage, and extent of biopsy tissue involvement. Most men with low-risk tumours are eligible for active surveillance, a programme of careful monitoring based on PSA and follow-up biopsies. Men with higher-risk cancers are best served with radical prostatectomy or radiation therapy.

228 Background: Many men with low risk prostate cancer on transrectal biopsy appear suitable for active surveillance (AS). Under staging and grading at diagnosis can result in delayed treatment and risk of poorer oncological outcomes. In most AS series about 30% men have active treatment at a median of two years for presumed disease progression/choice but this may represent disease mischaracterised at initial biopsy. So it is essential to accurately stratify patients before surveillance. We have routinely offered transperineal sector prostate biopsies (TPSB), using 24-32 cores, to all patients considering AS. Methods: 350 patients with apparent low to intermediate risk prostate cancer after transrectal prostate biopsy (TRUS Bx) underwent transperineal sector biopsies. Results: Median age 64 yrs (38–84). Median PSA 7.2 ug/l (0.14–58). 190 had Gleason 3+3, 115 had Gleason 3+4 and 45 >3+4 disease. 145 (41%) patients elected for definitive treatment, in 112 because there was an upgrade or higher disease volume compared with the original TRUS Bx. 33 patients chose definitive treatment rather than continued AS. 205 (59%) patients entered our AS programme, in 25 follow up data is incomplete leaving 180 for analysis. 61 have had repeat TPSB within our protocol and at a median follow up at 2 years in 56/61 (92%) the Gleason score and volume of disease was unchanged. Only 5/180, 2.8% have had treatment for disease progression and additionally 4/180 (2.2%) have chosen active intervention over continued surveillance, despite no evidence of progression. Conclusions: TRUS biopsies under-estimate Gleason grade or cancer volume compared with TPSB. In our cohort of AS patients only 2.8%, at a median follow up of two years, have transferred to definitive treatment for disease progression. TPSB provides the best method to exclude higher risk disease from AS programmes.
