The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors’ suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 61-year-old man presents with stage II prostate cancer after a period of active surveillance. Work-up reveals T1cN0M0 carcinoma, a prostate-specific antigen (PSA) level of 4.8 ng/mL, and Grade Group II (highest Gleason 3+4) in three cores of 12 taken, at the right mid-gland and right apex. The patient has been on active surveillance for the past 16 months. He was originally diagnosed after biopsy for an elevated PSA with stage I prostate cancer, T1cN0M0; PSA, 4.5 ng/mL; Grade Group 1 (Gleason 3+3) in one core of 12 taken, also at the right mid-gland. A multiparametric magnetic resonance imaging scan showed a heterogeneous peripheral zone without a dominant lesion and a calculated prostate volume of 28 mL. His medical history includes hypercholesterolemia, for which he takes atorvastatin. He is otherwise healthy and has no other significant medical or surgical history. His father had prostate cancer in his 70s and died of other causes at 89 years of age. The patient reports 2- to 3-hour urinary frequency and 0 to 1 nocturia, and has no difficulty obtaining or maintaining an erection. After meeting with his urologist, he sees a radiation oncologist.

The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A 67-year-old retired engineering professor was found to have a prostate-specific antigen (PSA) level of 11 ng/mL on a screening test at his annual physical examination. A digital rectal examination revealed a nodule on the right side. He underwent a transrectal ultrasound-guided prostate biopsy that was notable for prostate adenocarcinoma, Gleason 3 + 4 = 7 (Gleason grade group 2; 30% Gleason 4 component) involving two cores (60% and 20% core involvement). A bone scan and pelvic computed tomography scan were negative for evidence of metastatic disease. (Should he undergo prostate magnetic resonance imaging? That seems rather common these days.) He was diagnosed with cT2b intermediate-risk localized prostate cancer (PCa) by National Comprehensive Cancer Network (NCCN) risk group and was seen in the multidisciplinary clinic to discuss management options (Table 1).

Abstract Background Active surveillance (AS) is generally recognized as the preferred option for men with low-risk prostate cancer. Current guidelines use prostate-specific antigen (PSA) of 10–20 ng/mL or low-volume biopsy Gleason grade group (GG) 2 as features that, in part, define the favorable intermediate-risk disease and suggest that AS may be considered for some men in this risk category. Methods We identified 26,548 men initially managed with AS aged <80 years, with clinically localized prostate cancer (cT1-2cN0M0), PSA ≤ 20 ng/mL, biopsy GG ≤ 2 with percent positive cores ≤33% and who converted to treatment with radical prostatectomy from the surveillance, epidemiology, and end results prostate with the watchful waiting database. Multivariable logistic regression was performed to determine predictors of adverse pathology at RP according to PSA level (<10 vs 10–20 ng/mL) and GG (1 vs 2). Results Of 1731 men with GG 1 disease and PSA 10–20 ng/mL, 382 (22.1%) harbored adverse pathology compared to 2340 (28%) of 8,367 men with GG 2 and a PSA < 10 ng/mL who had adverse pathology at RP. On multivariable analysis, the odds of harboring adverse pathology with a PSA 10–20 ng/mL (odds ratio [OR] 1.87, 95% confidence interval [CI] 1.71–2.05, p < 0.001) was less than that of GG 2 (OR 2.56, 95%CI 2.40–2.73, p < 0.001) after adjustment. Conclusions Our results support extending AS criteria more permissively to carefully selected men with PSA 10–20 ng/mL and GG 1 disease.

The Oncology Grand Rounds series is designed to place original reports published in the Journal into clinical context. A case presentation is followed by a description of diagnostic and management challenges, a review of the relevant literature, and a summary of the authors’ suggested management approaches. The goal of this series is to help readers better understand how to apply the results of key studies, including those published in Journal of Clinical Oncology, to patients seen in their own clinical practice. A urologist referred a 69-year-old man for a radiotherapy opinion regarding a recently diagnosed adenocarcinoma of the prostate. Annual serum prostate-specific antigen (PSA) testing over 7 years demonstrated a rise in PSA from 1.36 ng/mL to 5.8 ng/mL, prompting a transrectal ultrasound that revealed a heterogeneous 37-mL gland containing no visualized hypoechoic nodules. Biopsy disclosed a Gleason score 3+4 (grade group 2) adenocarcinoma of the prostate. The synoptic report stated that six of 14 cores and 17% of the tissue were involved, with the greatest core involvement being 80% at the right apex. Perineural invasion was present without lymphovascular invasion. Disease was present bilaterally at the base, midgland, and apex.His medical history was significant only for treated peptic ulcer disease and he was taking no medication. His International Prostate Symptom Score was six of 35, and he reported being sexually active with good erectile function. There was no family history of prostate cancer. He is retired. Digital rectal examination revealed moderate benign prostatic hypertrophy with no suspicious nodules. A staging computerized tomography (CT) scan of the abdomen and pelvis and a whole-body bone scan ordered by his referring urologist reported no evidence of metastatic disease. The patient had discussed surgical options with his urologist and now wished to consider radiotherapy approaches.

Objective: The last edition of the AJCC staging system eliminated the pT2 subclassification of prostate cancer (PCa). Our objective was to evaluate the association of pT2 subclassification with the oncological results of patients with PCa who underwent radical prostatectomy (RP). Material and methods: We evaluated 367 patients who underwent RP between 2009 and 2016, with pT2 disease in the final pathological evaluation. We assessed differences in rates of biochemical recurrence (BCR), metastasis and mortality between T2 substages (pT2a/b vs pT2c). Results: Fifty-three (14.4%) patients presented pT2a/b disease and 314 (85.6%) pT2c disease. The mean follow-up time was 4.9 ± 2.6 years. Grade group scores (p = 0.1) and prostate specific antigen (PSA) (p = 0.2) did not differed between pT2 substages. The rate of BCR in pT2a/b and pT2c patients was 11.3% and 18.2%, respectively (p = 0.2). Five (9.4%) patients with pT2a/b and 45 (14.3%) with pT2c substage underwent salvage radiotherapy (p = 0.3). The rate of positive surgical margins did not differ between groups (p = 0.2). Seven (2.2%) patients with pT2c had lymph nodes or distant metastases. The overall survival was 92.5% and 93.6% in pT2a/b and pT2c, respectively (p = 0.2). Conclusion: Our results are in accordance with the changes introduced in the 8th edition of the AJCC staging system in which the pT2 subclassification was eliminated.

PURPOSE: To assess how active surveillance for prostate cancer is apportioned across specialties and how testing patterns and transition to treatment vary by specialty. METHODS: We used a 20% national sample of Medicare claims to identify men diagnosed with prostate cancer from 2010 through 2016 initiating surveillance (N = 13,048). Patients were assigned to the physician responsible for the bulk of surveillance care based on billing patterns. Freedom from treatment was assessed by specialty of the responsible physician (urology, radiation oncology, medical oncology, and primary care). Multinomial logistic regression models were used to examine associations between specialty and treatment patterns. RESULTS: Urologists were responsible for surveillance in 93.7% of patients in 2010 and 96.2% of patients in 2016 ( P for trend = .01). Testing patterns varied by specialty. For example, patients of medical oncologists had more frequent prostate-specific antigen testing compared with patients of urologists (1.85 v 2.39 tests per year, respectively; P < .01). Three years after diagnosis, a significantly smaller proportion of patients managed by radiation oncologists (64.3%) remained on surveillance compared with patients managed by other physicians (75.8%-79.5%; P < .01). Although radiation was the most common treatment among all men who transitioned to treatment, a disproportionate percentage of patients followed by radiation oncologists (28.9%) ultimately underwent radiation compared with patients followed by other physicians (15.1%-15.4%; P < .01). CONCLUSION: Nontrivial percentages of patients on active surveillance are managed by physicians outside of urology. Given the interspecialty variations observed, efforts to strengthen the evidence underlying surveillance pathways and to engage other specialties in guideline development are needed.

Prostate cancer is the most common cancer to effect men and the second most common cause of cancer-related death. Premalignant change or prostatic intraepithelial neoplasia has been detected within the prostate glands of men under 30 years of age. The incidence of prostate cancer remains negligible until men reach their 40s from whence it rises steadily and by 80 years 70% of men have detectable tumours at autopsy (1). A majority of prostate cancers arise from the peripheral zone of the prostate and rarely cause obstructive symptoms. Consequently, prostate cancers have historically presented late, with symptoms of metastatic disease. The advent of prostate-specific antigen (PSA) testing has produced a stage shift so that at present over 90% of prostate cancers are diagnosed as organ-confined disease. PSA diagnosis has unmasked a subset of prostate tumours that exhibit an indolent growth pattern and appear destined to remain organ-confined tumours the patient dies with, and not from. US SEER data estimates a 50-year-old man has a 42% chance of developing prostate cancer but only a 3.6% chance of dying from the disease. Features, either clinical or molecular, which would allow clinicians to clearly differentiate indolent from aggressive disease while still at the organ-confined stage, have yet to be identified (1). Adenocarcinoma is the predominant histological subtype of prostate cancer, accounting for 95% of tumours. Prostatic adenocarcinomas arise from androgen receptor-positive epithelial cells. On histological examination, prostate cancers appear multifocal and demonstrate heterogeneity both within individual tumours and across populations. This has created an obstacle as researchers attempt to subclassify prostate cancer and identify the molecular defects responsible for driving prostatic carcinogenesis (1). Of prostate cancers, 80–90% are androgen receptor-positive at diagnosis (2), thus to date the androgen–androgen receptor axis is the sole molecular feature of this disease that has been successfully harnessed as a therapeutic target.

PURPOSE The 17-gene Onco type DX Genomic Prostate Score (GPS) test predicts adverse pathology (AP) in patients with low-risk prostate cancer treated with immediate surgery. We evaluated the GPS test as a predictor of outcomes in a multicenter active surveillance cohort. MATERIALS AND METHODS Diagnostic biopsy tissue was obtained from men enrolled at 8 sites in the Canary Prostate Active Surveillance Study. The primary endpoint was AP (Gleason Grade Group [GG] ≥ 3, ≥ pT3a) in men who underwent radical prostatectomy (RP) after initial surveillance. Multivariable regression models for interval-censored data were used to evaluate the association between AP and GPS. Inverse probability of censoring weighting was applied to adjust for informative censoring. Predictiveness curves were used to evaluate how models stratified risk of AP. Association between GPS and time to upgrade on surveillance biopsy was evaluated using Cox proportional hazards models. RESULTS GPS results were obtained for 432 men (median follow-up, 4.6 years); 101 underwent RP after a median 2.1 years of surveillance, and 52 had AP. A total of 167 men (39%) upgraded at a subsequent biopsy. GPS was significantly associated with AP when adjusted for diagnostic GG (hazards ratio [HR]/5 GPS units, 1.18; 95% CI, 1.04 to 1.44; P = .030), but not when also adjusted for prostate-specific antigen density (PSAD; HR, 1.85; 95% CI, 0.99 to 4.19; P = .066). Models containing PSAD and GG, or PSAD, GG, and GPS may stratify risk better than a model with GPS and GG. No association was observed between GPS and subsequent biopsy upgrade ( P = .48). CONCLUSION In our study, the independent association of GPS with AP after initial active surveillance was not statistically significant, and there was no association with upgrading in surveillance biopsy. Adding GPS to a model containing PSAD and diagnostic GG did not significantly improve stratification of risk for AP over the clinical variables alone.
