Abstract
BACKGROUND Despite the extensive literature supporting distress screening at relevant transitions of care, the implementation of distress screening remains limited in ambulatory surgery settings. Our multidisciplinary team completed a pilot study to assess the feasibility and acceptability of including a standardized psychosocial assessment, the Distress Thermometer (DT), with the collection of admission vital signs by Patient Care Technicians (PCTs) in patients undergoing oncology surgery. METHODS We assessed feasibility by the response rate and acceptability through discussions with the PCTs. RESULTS Of the 189 men who underwent radical prostatectomy at our center, 71 were approached with the DT scale, and all patients who were approached completed the DT with no missing data. The staff reported no issues with data collection. A total of 21/71 (30%; 95% CI 19%, 42%) reported a clinically relevant distress DT ≥ 4. CONCLUSION Our results demonstrated that incorporating the DT into vital sign collection was feasible, acceptable, and provided a valuable assessment.

Electronic Patient-Reported Symptoms After Ambulatory Cancer Surgery. JAMA Surg 2024; 159:554-561. [PMID: 38477892 PMCID: PMC10938249 DOI: 10.1001/jamasurg.2024.0133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2023] [Accepted: 12/09/2023] [Indexed: 03/14/2024]
Abstract
Importance Complex cancer procedures are now performed in the ambulatory surgery setting. Remote symptom monitoring (RSM) with electronic patient-reported outcomes (ePROs) can identify patients at risk for acute hospital encounters. Defining normal recovery is needed to set patient expectations and optimize clinical team responses to manage evolving problems in real time. Objective To describe the patterns of postoperative recovery among patients undergoing ambulatory cancer surgery with RSM using an ePRO platform-the Recovery Tracker. Design, Setting, and Participants In this retrospective cohort study, patients who underwent 1 of 5 of the most common procedures (prostatectomy, nephrectomy, mastectomy, hysterectomy, or thyroidectomy) at the Josie Robertson Surgery Center at Memorial Sloan Kettering Cancer Center from September 2016 to June 2022. Patients completed the Recovery Tracker, a brief ePRO platform assessing symptoms for 10 days after surgery. Data were analyzed from September 2022 to May 2023. Main Outcomes and Measures Symptom severity and interference were estimated by postoperative day and procedure. Results A total of 12 433 patients were assigned 110 936 surveys. Of these patients, 7874 (63%) were female, and the median (IQR) age at surgery was 57 (47-65) years. The survey response rate was 87% (10 814 patients responding to at least 1 of 10 daily surveys). Among patients who submitted at least 1 survey, the median (IQR) number of surveys submitted was 7 (4-8), and each assessment took a median (IQR) of 1.7 (1.2-2.5) minutes to complete. Symptom burden was modest in this population, with the highest severity on postoperative days 1 to 3. Pain was moderate initially and steadily improved. Fatigue was reported by 6120 patients (57%) but was rarely severe. Maximum pain and fatigue responses (very severe) were reported by 324 of 10 814 patients (3%) and 106 of 10 814 patients (1%), respectively. The maximum pain severity (severe or very severe) was highest after nephrectomy (92 of 332 [28%]), followed by mastectomy with reconstruction (817 of 3322 [25%]) and prostatectomy (744 of 3543 [21%]). Nausea (occasionally, frequently, or almost constantly) was common and experienced on multiple days by 1485 of 9300 patients (16%), but vomiting was less common (139 of 10 812 [1%]). Temperature higher than 38 °C was reported by 740 of 10 812 (7%). Severe or very severe shortness of breath was reported by 125 of 10 813 (1%). Conclusions and Relevance Defining detailed postoperative symptom burden through this analysis provides valuable data to inform further implementation and maintenance of RSM programs in surgical oncology patients. These data can enhance patient education, set expectations, and support research to allow iterative improvement of clinical care based on the patient-reported experience after discharge.

Impact of Replacing Fentanyl With Hydromorphone as the First-Line Postoperative Opioid Among Patients Undergoing Outpatient Cancer Surgery. J Perianesth Nurs 2024:S1089-9472(23)01051-1. [PMID: 38493405 DOI: 10.1016/j.jopan.2023.11.007] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/27/2023] [Revised: 11/10/2023] [Accepted: 11/11/2023] [Indexed: 03/18/2024]
Abstract
PURPOSE In response to a nationwide fentanyl shortage, our institution assessed whether changing our first-line postoperative intravenous opioid from fentanyl to hydromorphone impacted patient outcomes. The primary research aim was to evaluate the association between first-line opioid and rapidity of recovery. DESIGN The study team retrospectively obtained data on all consecutive patients extracted from the electronic medical record. The rapidity of recovery was defined as the time from entry into the postanesthesia care unit to the transition to Phase 2 for ambulatory extended recovery patients and as the length of total postanesthesia care unit stay for outpatients. METHODS Following intent-to-treat-principles, we tested the association between study period and rapidity of recovery (a priori clinically meaningful difference: 20 minutes) using multivariable linear regression, adjusting for anesthesia type (general vs monitored anesthesia care), American Society of Anesthesiologst physical status (ASA) score (1-2 vs 3-4), age, service, robotic procedure, and surgery start time. FINDINGS Ambulatory extended recovery patients treated in the hydromorphone period had, on average, a 0.25 minute (95% confidence interval [CI] -6.5, 7.0), nonstatistically significant (P > .9) longer time to transition. For outpatient procedures, those who received hydromorphone had, on average, 8.5-minute longer stays (95% CI 3.7-13, P < .001). Although we saw statistical evidence of an increased risk of resurgery associated with receiving hydromorphone (0.5%; 95% CI -0.1%, 1.0%; P = .039 on univariate analysis), the size of the estimate is clinically and biologically implausible and is most likely a chance finding related either to multiple testing or confounding. CONCLUSIONS The multidisciplinary team concluded that the increase in postoperative length of stay associated with hydromorphone was not clinically significant and the decrease waste of prefilled syringes outweighed the small potential increased risk of resurgery compared to the shorter-acting fentanyl. We will therefore use hydromorphone moving forward.

Convergent evolution of BRCA2 reversion mutations under therapeutic pressure by PARP inhibition and platinum chemotherapy. NPJ Precis Oncol 2024; 8:34.

Abstract
Reversion mutations that restore wild-type function of the BRCA gene have been described as a key mechanism of resistance to Poly(ADP-ribose) polymerase (PARP) inhibitor therapy in BRCA-associated cancers. Here, we report a case of a patient with metastatic castration-resistant prostate cancer (mCRPC) with a germline BRCA2 mutation who developed acquired resistance to PARP inhibition. Extensive genomic interrogation of cell-free DNA (cfDNA) and tissue at baseline, post-progression, and postmortem revealed ten unique BRCA2 reversion mutations across ten sites. While several of the reversion mutations were private to a specific site, nine out of ten tumors contained at least one mutation, suggesting a powerful clonal selection for reversion mutations in the presence of therapeutic pressure by PARP inhibition. Variable cfDNA shed was seen across tumor sites, emphasizing a potential shortcoming of cfDNA monitoring for PARPi resistance. This report provides a genomic portrait of the temporal and spatial heterogeneity of prostate cancer under the selective pressure of a PARP inhibition and exposes limitations in the current strategies for detection of reversion mutations.

The oncologic risk of magnetic resonance imaging-targeted and systematic cores in patients treated with radical prostatectomy. Cancer 2023; 129:3790-3796. [PMID: 37584213 DOI: 10.1002/cncr.34981] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 05/25/2023] [Accepted: 05/26/2023] [Indexed: 08/17/2023]
Abstract
BACKGROUND Magnetic resonance imaging (MRI)-targeted prostate biopsy (MRI-biopsy) detects high-Grade Group (GG) prostate cancers not identified by systematic biopsy (S-biopsy). However, questions have been raised whether cancers detected by MRI-biopsy and S-biopsy, grade-for-grade, are of equivalent oncologic risk. The authors evaluated the relative oncologic risk of GG diagnosed by S-biopsy and MRI-biopsy. METHODS This was a retrospective analysis of all patients who had both MRI-biopsy and S-biopsy and underwent with prostatectomy (2014-2022) at Memorial Sloan Kettering Cancer Center. Three logistic regression models were used with adverse pathology as the primary outcome (primary pattern 4, any pattern 5, seminal vesicle invasion, or lymph node involvement). The first model included the presurgery prostate-specific antigen level, the number of positive and negative S-biopsy cores, S-biopsy GG, and MRI-biopsy GG. The second model excluded MRI-biopsy GG to obtain the average risk based on S-biopsy GG. The third model excluded S-biopsy GG to obtain the risk based on MRI-biopsy GG. A secondary analysis using Cox regression evaluated the 12-month risk of biochemical recurrence. RESULTS In total, 991 patients were identified, including 359 (36%) who had adverse pathology. MRI-biopsy GG influenced oncologic risk compared with S-biopsy GG alone (p < .001). However, if grade was discordant between biopsies, then the risk was intermediate between grades. For example, the average risk of advanced pathology for patients who had GG2 and GG3 on S-biopsy was 19% and 66%, respectively, but the average risk was 47% for patients who had GG2 on S-biopsy and patients who had GG3 on MRI-biopsy. The equivalent estimates for 12-month biochemical recurrence were 5.8%, 15%, and 10%, respectively. CONCLUSIONS The current findings cast doubt on the practice of defining risk group based on the highest GG. Because treatment algorithms depend fundamentally on GG, further research is urgently required to assess the oncologic risk of prostate tumors depending on detection technique. PLAIN LANGUAGE SUMMARY Using magnetic resonance imaging (MRI) to help diagnose prostate cancer can help identify more high-grade cancers than using a systematic template biopsy alone. However, we do not know if high-grade cancers diagnosed with the help of an MRI are as dangerous to the patient as high-grade cancers diagnosed with a systematic biopsy. We examined all of our patients who had an MRI biopsy and a systematic biopsy and then had their prostates removed to find out if these patients had risk factors and signs of aggressive cancer (cancer that spread outside the prostate or was very high grade). We found that, if there was a difference in grade between the systematic biopsy and the MRI-targeted biopsy, the risk of aggressive cancer was between the two grades.

Outcomes of Grade Group 2 and 3 Prostate Cancer on Initial Versus Confirmatory Biopsy: Implications for Active Surveillance. Eur Urol Focus 2023; 9:662-668. [PMID: 36566100 PMCID: PMC10285029 DOI: 10.1016/j.euf.2022.12.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2022] [Revised: 11/21/2022] [Accepted: 12/12/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND Active surveillance (AS) is recommended as the preferred treatment for men with low-risk disease. In order to optimize risk stratification and exclude undiagnosed higher-grade disease, most AS protocols recommend a confirmatory biopsy. OBJECTIVE We aimed to compare outcomes among men with grade group (GG) 2/3 prostate cancer on initial biopsy with those among men whose disease was initially GG1 but was upgraded to GG2/3 on confirmatory biopsy. DESIGN, SETTING, AND PARTICIPANTS We reviewed patients undergoing radical prostatectomy (RP) in two cohorts: "immediate RP group," with GG2/3 cancer on diagnostic biopsy, and "AS group," with GG1 cancer on initial biopsy that was upgraded to GG2/3 on confirmatory biopsy. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Probabilities of biochemical recurrence (BCR) and salvage therapy were determined using multivariable Cox regression models with risk adjustment. Risks of adverse pathology at RP were also compared using logistic regression. RESULTS AND LIMITATIONS The immediate RP group comprised 4009 patients and the AS group comprised 321 patients. The AS group had lower adjusted rates of adverse pathology (27% vs 35%, p = 0.003). BCR rates were lower in the AS group, although this did not reach conventional significance (hazard ratio [HR] 0.73, 95% confidence interval [CI] 0.50-1.06, p = 0.10) compared with the immediate RP group. Risk-adjusted 1- and 5-yr BCR rates were 4.6% (95% CI 3.0-6.5%) and 10.4% (95% CI 6.9-14%), respectively, for the AS group compared with 6.3% (95% CI 5.6-7.0%) and 20% (95% CI 19-22%), respectively, in the immediate RP group. A nonsignificant association was observed for salvage treatment-free survival favoring the AS group (HR 0.67, 95% CI 0.42, 1.06, p = 0.087). CONCLUSIONS We found that men with GG1 cancer who were upgraded on confirmatory biopsy tend to have less aggressive disease than men with the same grade found at initial biopsy. These results must be confirmed in larger series before recommendations can be made regarding a more conservative approach in men with upgraded pathology on surveillance biopsy. PATIENT SUMMARY We studied men with low-risk prostate cancer who were initially eligible for active surveillance but presented with more aggressive cancer on confirmatory biopsy. We found that outcomes for these men were better than the outcomes for those diagnosed initially with more serious cancer.

Abstract
OBJECTIVE To assess long-term outcomes with robotic versus laparoscopic/thoracoscopic and open surgery for colorectal, urologic, endometrial, cervical, and thoracic cancers. BACKGROUND Minimally invasive surgery provides perioperative benefits and similar oncological outcomes compared with open surgery. Recent robotic surgery data have questioned long-term benefits. METHODS A systematic review and meta-analysis of cancer outcomes based on surgical approach was conducted based on Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines using Pubmed, Scopus, and Embase. Hazard ratios for recurrence, disease-free survival (DFS), and overall survival (OS) were extracted/estimated using a hierarchical decision tree and pooled in RevMan 5.4 using inverse-variance fixed-effect (heterogeneity nonsignificant) or random effect models. RESULTS Of 31,204 references, 199 were included (7 randomized, 23 database, 15 prospective, 154 retrospective studies)-157,876 robotic, 68,007 laparoscopic/thoracoscopic, and 234,649 open cases. Cervical cancer: OS and DFS were similar between robotic and laparoscopic [1.01 (0.56, 1.80), P =0.98] or open [1.18 (0.99, 1.41), P =0.06] surgery; 2 papers reported less recurrence with open surgery [2.30 (1.32, 4.01), P =0.003]. Endometrial cancer: the only significant result favored robotic over open surgery [OS; 0.77 (0.71, 0.83), P <0.001]. Lobectomy: DFS favored robotic over thoracoscopic surgery [0.74 (0.59, 0.93), P =0.009]; OS favored robotic over open surgery [0.93 (0.87, 1.00), P =0.04]. Prostatectomy: recurrence was less with robotic versus laparoscopic surgery [0.77 (0.68, 0.87), P <0.0001]; OS favored robotic over open surgery [0.78 (0.72, 0.85), P <0.0001]. Low-anterior resection: OS significantly favored robotic over laparoscopic [0.76 (0.63, 0.91), P =0.004] and open surgery [0.83 (0.74, 0.93), P =0.001]. CONCLUSIONS Long-term outcomes were similar for robotic versus laparoscopic/thoracoscopic and open surgery, with no safety signal or indication requiring further research (PROSPERO Reg#CRD42021240519).

Abstract
PURPOSE We aimed to report the morbidity profile of salvage radical prostatectomy (SRP) after radiotherapy failure and assess the impact of minimally invasive surgery (MIS) on postoperative complications and functional outcomes. MATERIALS AND METHODS Between 1985 and 2019, a total of 293 patients underwent SRP; 232 underwent open SRP; and 61 underwent laparoscopic SRP with or without robotic assistance. Complications were recorded and classified into standardized categories per the Clavien-Dindo classification. RESULTS Twenty-nine patients (10%) experienced grade 3 complications within 30 days, 22 (9.5%) after open and 7 (11%) after MIS (p = 0.6). Between 30 and 90 days after surgery, 7.3% of patients in the open group and 10% in the MIS group had grade 3 complications (p = 0.5). The most common complication was bladder neck contracture (BNC), representing 40% of the 30-90 day complications. Within one year of SRP, 81 patients (31%, 95% CI 25%, 37%) developed BNC; we saw non-significant lower rates in MIS (25 vs 32%; p = 0.4). Functional outcomes were poor after SRP and showed no difference between open and MIS groups for urinary continence (16 vs 18%, p = 0.7) and erectile function (7 vs 13%, p = 0.4). 5 year cancer-specific survival and overall survival was 95% and 88% for the entire cohort, respectively. CONCLUSIONS Our outcomes suggest poor functional recovery after SRP, regardless of the operative approach. Currently there is no evidence favoring the use of open or MIS approach. Further studies are required to ensure comparable outcomes between these approaches.

Abstract
BACKGROUND Accurate markers for prostate cancer (PC) risk stratification could aid decision-making for initial management strategies. The 4Kscore has an undefined role in predicting outcomes after radical prostatectomy (RP). METHODS We included 1476 patients with 4Kscore measured prior to RP at two institutions. The 4Kscore was assessed for prediction of adverse pathology at RP and biochemical recurrence (BCR) relative to a clinical model. We pre-specified that all analyses would be assessed in biopsy Grade Group 1 (GG1) or 2 (GG2) PC patients, separately. RESULTS The 4Kscore increased discrimination for adverse pathology in all patients (delta area under the receiver operative curve (AUC) 0.009, 95% confidence interval (CI) 0.002, 0.016; clinical model AUC 0.767), driven by GG1 (delta AUC 0.040, 95% CI 0.006, 0.073) rather than GG2 patients (delta AUC 0.005, 95% CI -0.012, 0.021). Adding 4Kscore improved prediction of BCR in all patients (delta C-index 0.014, 95% CI 0.007, 0.021; preop-BCR nomogram C-index 0.738), again with larger changes in GG1 than in GG2. CONCLUSIONS This study validates prior investigations on the use of 4Kscore in men with biopsy-confirmed PC. Men with GG1 PC and a high 4Kscore may benefit from additional testing to guide treatment selection. Further research is warranted regarding the value of the 4Kscore in men with biopsy GG2 PC.

Abstract
BACKGROUND We describe the implementation of enhanced recovery after surgery (ERAS) programs designed to minimize postoperative nausea and vomiting (PONV) and pain and reduce opioid use in patients undergoing selected procedures at an ambulatory cancer surgery center. Key components of the ERAS included preoperative patient education regarding the postoperative course, liberal preoperative hydration, standardized PONV prophylaxis, appropriate intraoperative fluid management, and multimodal analgesia at all stages. METHODS We retrospectively reviewed data on patients who underwent mastectomy with or without immediate reconstruction, minimally invasive hysterectomy, thyroidectomy, or minimally invasive prostatectomy from the opening of our institution on January 2016 to December 2018. Data collected included use of total intravenous anesthesia (TIVA), rate of PONV rescue, time to first oral opioid, and total intraoperative and postoperative opioid consumption. Compliance with ERAS elements was determined for each service. Quality outcomes included time to first ambulation, postoperative length of stay (LOS), rate of reoperation, rate of transfer to acute care hospital, 30-day readmission, and urgent care visits ≤30 days. RESULTS We analyzed 6781 ambulatory surgery cases (2965 mastectomies, 1099 hysterectomies, 680 thyroidectomies, and 1976 prostatectomies). PONV rescue decreased most appreciably for mastectomy (28% decrease; 95% confidence interval [CI], -36 to -22). TIVA use increased for both mastectomies (28%; 95% CI, 20-40) and hysterectomies (58%; 95% CI, 46-76). Total intraoperative opioid administration decreased over time across all procedures. Time to first oral opioid decreased for all surgeries; decreases ranged from 0.96 hours (95% CI, 2.1-1.4) for thyroidectomies to 3.3 hours (95% CI, 4.5 to -1.7) for hysterectomies. Total postoperative opioid consumption did not change by a clinically meaningful degree for any surgery. Compliance with ERAS measures was generally high but varied among surgeries. CONCLUSIONS This quality improvement study demonstrates the feasibility of implementing ERAS at an ambulatory surgery center. However, the study did not include either a concurrent or preintervention control so that further studies are needed to assess whether there is an association between implementation of ERAS components and improvements in outcomes. Nevertheless, we provide benchmarking data on postoperative outcomes during the first 3 years of ERAS implementation. Our findings reflect progressive improvement achieved through continuous feedback and education of staff.

Abstract
Minimally invasive operative techniques and enhanced recovery after surgery (ERAS) protocols have transformed clinical practice and made it possible to perform increasingly complex oncologic procedures in the ambulatory setting, with recovery at home after a single overnight stay. Capitalizing on these changes, Memorial Sloan Kettering Cancer Center's Josie Robertson Surgery Center (JRSC), a freestanding ambulatory surgery facility, was established to provide both outpatient procedures and several surgeries that had previously been performed in the inpatient setting, newly transitioned to this ambulatory extended recovery (AXR) model. However, the JRSC core mission goes beyond rapid recovery, aiming to be an innovation center with a focus on superlative patient experience and engagement, efficiency, and data-driven continuous improvement. Here, we describe the JRSC genesis, design, care model, and outcome tracking and quality improvement efforts to provide an example of successful, patient-centered surgical care for select patients undergoing relatively complex procedures in an ambulatory setting.

Abstract
Abstract
Rare cell types in the prostate are reported to have stem cell properties based on organ regeneration potential following castration. Here, we use single cell RNA-seq (scRNA-Seq) to characterize these populations from the murine and human prostate in hormonally intact and androgen deprived conditions. Prostate cells from hormonally intact mice partitioned into one large subset of basal epithelial cells, another large subset of luminal epithelial cells, which we designate luminal 1 and two rare luminal populations: luminal 2 and luminal 3. Luminal cells that persist following castration display enhanced organoid regeneration potential, particularly within 1-2 days of androgen addback, and contribute equipotently to prostatic regeneration as revealed by lineage tracing. This regeneration is mediated, in part, through the orchestrated expression of Nrg2, Igf1, Fgf10 and Rspo3 by distinct populations of androgen-responsive mesenchymal and smooth muscle cells. Thus, luminal cells that persist post-castration undergo a cell state change that primes a proliferative response to microenvironment signals, analogous to other models of tissue injury such as liver damage.

Abstract
Androgen deprivation is the cornerstone of prostate cancer treatment. It results in involution of the normal gland to ~90% of its original size because of the loss of luminal cells. The prostate regenerates when androgen is restored, a process postulated to involve stem cells. Using single-cell RNA sequencing, we identified a rare luminal population in the mouse prostate that expresses stemlike genes (Sca1 + and Psca +) and a large population of differentiated cells (Nkx3.1 +, Pbsn +). In organoids and in mice, both populations contribute equally to prostate regeneration, partly through androgen-driven expression of growth factors (Nrg2, Rspo3) by mesenchymal cells acting in a paracrine fashion on luminal cells. Analysis of human prostate tissue revealed similar differentiated and stemlike luminal subpopulations that likewise acquire enhanced regenerative potential after androgen ablation. We propose that prostate regeneration is driven by nearly all persisting luminal cells, not just by rare stem cells.

Abstract
PURPOSE We studied the risk of metastatic prostate cancer development in men with Grade Group 2 disease managed with active surveillance at Memorial Sloan Kettering Cancer Center. MATERIALS AND METHODS A total of 219 men with Grade Group 2 prostate cancer had disease managed with active surveillance between 2000 and 2017. Biopsy was performed every 2 to 3 years, or upon changes in magnetic resonance imaging, prostate specific antigen level or digital rectal examination. The primary outcome was development of distant metastasis. The Kaplan-Meier method was used to estimate treatment-free survival. RESULTS Median age at diagnosis was 67 years (IQR 61-72), median prostate specific antigen was 5 ng/ml (IQR 4-7) and most patients (69%) had nonpalpable disease. During followup 64 men received treatment, including radical prostatectomy in 36 (56%), radiotherapy in 20 (31%), hormone therapy in 3 (5%) and focal therapy in 5 (8%). Of the 36 patients who underwent radical prostatectomy 32 (89%) had Grade Group 2 disease on pathology and 4 (11%) had Grade Group 3 disease. Treatment-free survival was 61% (95% CI 52-70) at 5 years and 49% (95% CI 37-60) at 10 years. Three men experienced biochemical recurrence, no men had distant metastasis and no men died of prostate cancer during the followup. Median followup was 3.1 years (IQR 1.9-4.9). CONCLUSIONS Active surveillance appears to be a safe initial management strategy in the short term for carefully selected and closely monitored men with Grade Group 2 prostate cancer treated at a tertiary cancer center. Definitive conclusions await further followup.

Role of Changes in Magnetic Resonance Imaging or Clinical Stage in Evaluation of Disease Progression for Men with Prostate Cancer on Active Surveillance. Eur Urol 2019; 77:501-507. [PMID: 31874726 DOI: 10.1016/j.eururo.2019.12.009] [Citation(s) in RCA: 51] [Impact Index Per Article: 10.2] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Accepted: 12/10/2019] [Indexed: 01/05/2023]
Abstract
BACKGROUND Active surveillance (AS) protocols rely on rectal examination, prostate-specific antigen, imaging, and biopsy to identify disease progression. OBJECTIVE To evaluate whether an AS regimen based on magnetic resonance imaging (MRI) or clinical stage changes can detect reclassification to grade group (GG) ≥2 disease compared with scheduled systematic biopsies. DESIGN, SETTING, AND PARTICIPANTS We identified a cohort of men initiated on AS between January 2013 and April 2016 at a single tertiary-care center. Patients completed confirmatory testing and prostate MRI prior to enrollment, then underwent laboratory and physical evaluation every 6 mo, MRI every 18 mo, and biopsy every 3yr. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS MRI results were evaluated using composite Likert/Prostate Imaging Reporting and Data System v2 scoring. MRI and clinical changes were assessed for association with disease progression. Univariable and multivariable regression models were used to predict upgrading on 3-yr biopsy. RESULTS AND LIMITATIONS At 3yr, of 207 men, 66 (32%) had≥GG2 at biopsy: 55 (83%) with GG2, 10 (15%) with GG3, and one (1.5%) with GG4. Among patients with a 3-yr MRI score of ≥3, 41% had≥GG2 disease, compared with 15% with an MRI score of <3 (p=0.0002). The MRI score increased in 48 men (23%), decreased in 27 (13%), and was unchanged in 132 (64%) men. Increases in MRI score were not associated with reclassification after adjusting for the 3-yr MRI score (p=0.9). Biopsying only for an increased MRI score or clinical stage would avoid 681 biopsies per 1000 men, at the cost of missing ≥GG2 disease in 169 patients. CONCLUSIONS An AS strategy that uses MRI or clinical changes to trigger prostate biopsy avoids many biopsies but misses an unacceptable amount of clinically significant disease. Prostate biopsy for men on AS should be performed at scheduled intervals, regardless of stable imaging or examination findings. PATIENT SUMMARY An active surveillance strategy for biopsy based only on increases in magnetic resonance imaging score or clinical stage will avoid many biopsies; however, it will miss many patients with clinically significant prostate cancer.

Abstract
PURPOSE The purpose of this paper is to determine the impact of having a patient-designated caregiver remain overnight with ambulatory extended recovery patients on early postoperative clinical outcomes. DESIGN/METHODOLOGY/APPROACH This was a retrospective cohort study of patients undergoing surgery requiring overnight stay in a highly resourced free-standing oncology ambulatory surgery center. Postoperative outcomes in patients who had caregivers stay with them overnight were compared with outcomes in those who did not. All other care was standardized. Primary outcomes were postoperative length of stay, hospital readmission rates, urgent care center (UCC) visits within 30 days and perioperative complication rates. FINDINGS Among patients staying overnight, 2,462 (57 percent) were accompanied by overnight caregivers. In this group, time to discharge was significantly lower. Readmissions (though rare) were slightly higher, though the difference was not statistically significant (p=0.059). No difference in early (<30 day) complications or UCC visits was noted. Presence of a caregiver overnight was not associated with important differences in outcomes, though further research in a less well-structured environment is likely to show a more robust benefit. Caregivers are still recommended to stay overnight if that is their preference as no harm was identified. ORIGINALITY/VALUE This study is unique in its evaluation of the clinical impact of having a caregiver stay overnight with ambulatory surgery patients. Little research has focused on the direct impact of the caregiver on patient outcomes, especially in the ambulatory setting. With increased adoption of minimally invasive surgical techniques and enhanced recovery pathways, a larger number of patients are eligible for short-stay ambulatory surgery. Factors that impact discharge and early postoperative complications are important.

Abstract
Purpose To verify the quality of pelvic lymph node dissection (PLND) performed at radical prostatectomy (RP) and its impact on nodal recurrence in patients undergoing salvage lymph node dissection (sLND). Materials and Methods Retrospective review of 48 patients who underwent sLND for presumed nodal recurrence, to describe the PLND characteristics at RP and correlate the anatomical sites and number of suspicious nodes reported in radiological imaging and final pathology of sLND. Results Overall, at RP, 8 (16.7%) did not undergo PLND, 32 (66.7%) and 8 (16.7%) received a “limited” (between external iliac vein and obturator nerve) and an “extended” (external iliac, hypogastric, and obturator) dissection, respectively. Median nodes removed during limited and extended dissection were 2 and 24, respectively. At sLND, the mean age was 61.3 years and median prostate specific antigen (PSA) was 1.07 ng/mL. Median nodes removed at sLND were 17 with a median of 2 positive nodes. Recurrent nodes were identified within the template of an extended PLND in 62.5%, 50.0% and 12.5% patients, respectively, following prior no, limited and extended dissection at RP. Recurrence outside the expected lymphatic drainage pathway was noted in 37.5% patients with prior extended dissection at RP. There was a correlation between imaging and pathology specimen in 83% for node location and 58.3% for number of anatomical sites involved. Conclusions In prostate cancer patients undergoing sLND, most had inadequate PLND at the original RP. Pattern of nodal recurrence may be influenced by the prior dissection and pre sLND imaging appears to underestimate the nodal recurrence.

Abstract
OBJECTIVE To describe fluctuations in prostate-specific antigen (PSA) levels in men managed with active surveillance (AS) to determine if a single PSA increase is a consistent measure to use to trigger intervention. PATIENTS AND METHODS We evaluated data on 541 patients undergoing AS between 1995 and 2011. PSA variation was described by studying the Kaplan-Meier probability of patients' PSA levels reaching 4 or 7 ng/mL, falling below those thresholds, and then rising to those thresholds again. We also examined PSA variation by calculating the Kaplan-Meier probability of a PSA change followed by an equal or greater change in the opposite direction. RESULTS We analysed data on 541 patients undergoing AS with a median (interquartile range [IQR]) of 8 (6-12) PSA measurements and undergoing AS for a median (IQR) of 4 (2-6) years. The 5-year estimate of the probability of reaching a threshold PSA of 7 ng/mL was 40% (95% confidence interval [CI] 35-46%) and the 5-year estimate of subsequently falling below this threshold was 90% (95% CI 82-95%). The 5-year estimate of a PSA direction change was 95% (95% CI 93-97%) overall and 56% (95% CI 51-61%) for PSA direction changes of ≥1 ng/mL. CONCLUSIONS We observed a high probability of variability in PSA levels for patients on AS. The probability of changes in PSA, defined by an increase to the specified thresholds or a rise >1 ng/mL within 6 months and subsequent decrease of equal or greater value on a subsequent measurement, increases over time; therefore, a single change in PSA level is not a reliable endpoint for patients on AS.

Ethnic variation in pelvimetric measures and its impact on positive surgical margins at radical prostatectomy. Urology 2010; 76:1092-6.

Abstract
OBJECTIVES We sought to evaluate the ethnic variation in pelvimetry and its impact as a predictor of positive surgical margins (PSM) at radical prostatectomy (RP). METHODS Preoperative MRI was performed in 482 Caucasian and 103 African American (AA) men undergoing RP without previous treatment from July 2003 to January 2005 and November 2001 to June 2007, respectively. We measured bony and soft tissue dimensions on magnetic resonance imaging (MRI) to evaluate the pelvic inlet, midplane, prostate size, and apical depth. Analysis of covariance was performed to determine the effect of ethnicity on the midpelvic area (MPA). We performed multivariate logistic regression analysis for prediction of overall and site-specific PSM. RESULTS AA men had a significantly steeper symphysis pubis angle (median, 43.1 vs. 41.3°, respectively, P = .001) and smaller MPA (median, 78.5 vs. 83.9 cm(2), respectively, P = .004). Ethnicity and BMI were found to have a significant effect on MPA. Apical depth of the prostate was identified as a significant independent predictor of apical PSM, with a more pronounced effect in AA men. Pelvimetric measures were not a significant predictor of other sites of PSM. CONCLUSIONS AA men have a significantly smaller MPA and steeper symphysis angle. The adverse impact of a deep pelvis, as measured by the apical prostatic depth on apical PSM was found to be greater in AA men. Evaluation of pelvic dimensions and prostate parameters in preoperative MRI may add to our understanding of their impact on surgical outcomes.

Abstract
OBJECTIVE To determine the effect of a deep and narrow pelvis on apical positive surgical margins (PSM) at radical prostatectomy (RP), controlling for other clinical and pathological variables and surgical approach, i.e. open retropubic (RRP) vs laparoscopic (LRP), as apical dissection is expected to be more challenging at RP with a prostate situated deep in a narrow pelvis. PATIENTS AND METHODS From July 2003 to January 2005, 512 consecutive patients with preoperative prostate magnetic resonance imaging (MRI) underwent RRP or LRP with no previous radio- or hormonal therapy. An additional 74 patients with preoperative MRI undergoing RP from December 2001 to June 2007 who had an apical PSM were also included, with 586 patients comprising the study population. Bony and soft-tissue pelvic dimensions, including interspinous distance (ISD), bony (BFW) and soft tissue (SW) pelvic width, apical prostate depth (AD) and symphysis pubis angle, were measured on preoperative MRI. The pelvic dimension index (PDI), bony width index (BWI) and soft-tissue width index (SWI) were defined as ISD/AD, BFW/AD and SW/AD, respectively. Multivariate logistic regression was used to assess the effect of pelvic dimensions on apical PSM, controlling for surgical approach and clinical and pathological variables. RESULTS There was no significant difference in ISD, BFW, SW or symphysis angle between patients with and without apical PSM. The AD was significantly greater in men with an apical PSM and consequently PDI, BWI and SWI were significantly lower in men with an apical PSM. Each of PDI, AD, BWI and SWI was a significant independent predictor of apical PSM, independent of surgical approach, and other clinicopathological variables. The main limitations of the study were that it was retrospective, and the relatively few patients with apical PSM. CONCLUSIONS Apical prostate depth is an independent risk factor for apical PSM at RP. MRI pelvimetry might allow for preoperative planning of the approach to RP.

Abstract
PURPOSE We evaluated predictors of freedom from biochemical recurrence in patients with pelvic lymph node metastasis at radical prostatectomy. MATERIALS AND METHODS Of 207 patients with lymph node metastasis treated with radical prostatectomy and bilateral pelvic lymph node dissection 45 received adjuvant androgen deprivation therapy and 162 did not. Cox proportional hazards regression models were used to investigate predictors of biochemical recurrence after radical prostatectomy. Recurrence probability was estimated using the Kaplan-Meier method. RESULTS A median of 13 lymph nodes were removed. Of the patients 122 had 1, 44 had 2 and 41 had 3 or greater positive lymph nodes. Of patients without androgen deprivation therapy 103 had 1, 35 had 2 and 24 had 3 or greater positive lymph nodes while 69 experienced biochemical recurrence. Median time to recurrence in patients with 1, 2 and 3 or greater lymph nodes was 59, 13 and 3 months, respectively. Only specimen Gleason score and the number of positive lymph nodes were independent predictors of biochemical recurrence. Recurrence-free probability 2 years after prostatectomy in men without androgen deprivation with 1 positive lymph node and a prostatectomy Gleason score of 7 or less was 79% vs 29% in those with Gleason score 8 or greater and 2 or more positive lymph nodes. CONCLUSIONS Prognosis in patients with lymph node metastasis depends on the number of positive lymph nodes and primary tumor Gleason grade. Of all patients with lymph node metastasis 80% had 1 or 2 positive nodes. A large subset of those patients had a favorable prognosis. Full bilateral pelvic lymph node dissection should be done in patients with intermediate and high risk cancer to identify those likely to benefit from metastatic node removal.

Abstract
BACKGROUND The lack of standardized reporting of the complications of radical prostatectomy in the literature has made it difficult to compare incidences across institutions and across different surgical approaches. OBJECTIVE To define comprehensively the incidence, severity, and timing of onset of medical and surgical complications of open retropubic prostatectomy (RP) and laparoscopic radical prostatectomy (LP) using a standardized reporting methodology to facilitate comparison. DESIGN, SETTING, AND PARTICIPANTS Between January 1999 and June 2007, 4592 consecutive patients underwent RP or LP without prior radiation or hormonal therapy. Median follow-up was 36.9 mo (interquartile range: 20.3-60.6). INTERVENTION Open or laparoscopic radical prostatectomy. MEASUREMENTS All medical and surgical complications of radical prostatectomy were captured and graded according to the modified Clavien classification and classified by timing of onset. RESULTS AND LIMITATIONS There were 612 medical complications in 467 patients (10.2%) and 1426 surgical complications in 925 patients (20.1%). The overall incidences of early minor and major medical and surgical complications for RP were 8.5% and 1.5% for medical and 11.4% and 4.9% for surgical complications, respectively. The overall incidences of early minor and major medical and surgical complications for LP were 14.2% and 2.3% for medical and 23.1% and 6.6% for surgical complications, respectively. On multivariate analysis, LP approach was associated with a higher incidence of any grade medical and surgical complications but a lower incidence of major surgical complications than RP. Six hundred fifty-two men (14.2%) visited the emergency department, and 240 men (5.2%) required readmission. The main limitation is the retrospective nature. CONCLUSIONS With standardized reporting, the incidence of some complications is higher than recognized in the literature. Although most complications are minor in severity, medical and surgical complications are observed in approximately 10% and 20% of patients, respectively. Accurate reporting of complications through a standardized methodology is essential for counseling patients regarding risk of complications, for identifying modifiable risk factors, and for facilitating comparison across institutions and approaches.

The response of patients with superficial bladder cancer to a second course of intravesical bacillus Calmette-Guerin. J Urol 1990; 143:710-2; discussion 712-3.

Abstract
Of 347 patients who received an initial 6-week course of intravesical bacillus Calmette-Guerin for superficial transitional cell carcinoma of the bladder 28 (8%) were treated with another course. Subsequent progression of disease (muscle infiltration, metastasis or local progression) occurred in 13 patients (46%). Of the 15 patients (54%) without progression 10 (36%) had a complete response and 5 (33%) had new tumors, and they were rendered free of disease after transurethral resection. The median duration of response to course 1 of bacillus Calmette-Guerin was shorter for patients with disease progression after course 2 than for those with no progression (15 and 27 months, respectively, p equals 0.05). The median followup after course 2 was 31.2 months (range 15.6 to 56.4 months). The median interval between courses 1 and 2 of intravesical bacillus Calmette-Guerin was 21.6 months (range 3.6 to 78.8 months). The interval from course 2 of bacillus Calmette-Guerin to progression correlated with the duration of response to course 1 of treatment (p equals 0.01). It appears that a subsequent treatment with bacillus Calmette-Guerin is most likely to be useful in patients who have a sustained response to the initial treatment.
