The oncologic risk of magnetic resonance imaging-targeted and systematic cores in patients treated with radical prostatectomy.

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.

Health-related Quality of Life After Robotic-assisted vs Open Radical Cystectomy: Analysis of a Randomized Trial.

PURPOSE: We compare health-related quality of life using a broad range of validated measures in patients randomized to robotic-assisted radical cystectomy vs open radical cystectomy. METHODS: We retrospectively analyzed patients that had enrolled in both a randomized controlled trial comparing robotic-assisted laparoscopic radical cystectomy vs open radical cystectomy and a separate prospective study of health-related quality of life. The prospective health-related quality of life study collected 14 patient-reported outcomes measures preoperatively and at 3, 6, 12, 18, and 24 months postoperatively. Linear mixed-effects models with an interaction term (study arm×time) were used to test for differences in mean domain scores and differing effects of approach over time, adjusting for baseline scores. RESULTS: A total of 72 patients were analyzed (n=32 robotic-assisted radical cystectomy, n=40 open radical cystectomy). From 3-24 months post-radical cystectomy, no significant differences in mean scores were detected. Mean differences were small in the following European Organization for Research and Treatment of Cancer QLQ-C30 (Core Quality of Life Questionnaire) domains: Global Quality of Life (-1.1; 95% CI -8.4, 6.2), Physical Functioning (-0.4; 95% CI -5.8, 5.0), Role Functioning (0.7; 95% CI -8.6, 10.0). Mean differences were also small in bladder cancer-specific domains (European Organization for Research and Treatment of Cancer QLQ-BLM30 [Muscle Invasive Bladder Cancer Quality of Life Questionnaire]): Body Image (2.9; 95% CI -7.2, 13.1), Urinary Symptoms (8.0; 95% CI -3.0, 19.0). In Urostomy Symptoms, there was a significant interaction term (P < .001) due to lower open radical cystectomy scores at 3 and 24 months. Other domains evaluating urinary, bowel, sexual, and psychosocial health-related quality of life were similar. CONCLUSIONS: Over a broad range of health-related quality of life domains comparing robotic-assisted radical cystectomy and open radical cystectomy, there are unlikely to be clinically relevant differences in the medium to long term, and therefore health-related quality of life over this time period should not be a consideration in choosing between approaches.

Predictive value of kallikrein forms and ß-microseminoprotein in blood from patients with evidence of detectable levels of PSA after radical prostatectomy.

PURPOSE: To determine whether ß-microseminoprotein or any of the kallikrein forms in blood-free, total or intact PSA or total hK2-predict metastasis in patients with evidence of detectable levels of PSA in blood after radical prostatectomy. METHOD: We determined marker concentrations in blood from 173 men treated with radical prostatectomy and evidence of detectable levels of PSA in the blood (PSA ≥ 0.05) after surgery between 2014 and 2015 and at least 1 year after any adjuvant therapy. We used Cox regression to determine whether any marker was associated with metastasis using both univariate and multivariable models that included standard clinical predictors. RESULTS: Overall, 42 patients had metastasis, with a median follow-up of 67 months among patients without an event. The levels of intact and free PSA and free-to-total PSA ratio were significantly associated with metastasis. Discrimination was highest for free PSA (c-index: 0.645) and free-to-total PSA ratio (0.625). Only free-to-total PSA ratio remained associated with overall metastasis (either regional or distant) after including standard clinical predictors (p = 0.025) and increased discrimination from 0.686 to 0.697. Similar results were found using distant metastasis as an outcome (p = 0.011; c-index increased from 0.658 to 0.723). CONCLUSION: Our results provide evidence that free-to-total PSA ratio can risk stratifying patients with evidence of detectable levels of PSA in blood after RP. Further research is warranted on the biology of prostate cancer markers in patients with evidence of detectable levels of PSA in blood after radical prostatectomy. Our findings on the free-to-total ratio for predicting adverse oncologic outcomes need to be validated in other cohorts.

Preoperative glucose in surgical oncology patient is not associated with postoperative outcomes after adjustment for frailty.

BACKGROUND: Observational studies have shown associations between even small elevations in preoperative glucose and poorer outcomes, including increased length of stay (LOS) and higher mortality. This has led to calls for aggressive glycemic control in the preoperative period, including delay of treatment until glucose is reduced. However, it is not known whether there is a direct causal effect of blood glucose or whether adverse outcomes result from overall poorer health in patients with higher glucose. METHODS: Analysis was performed using a retrospective database of patients aged 65 and older who underwent cancer surgery. The last measured preoperative glucose was the exposure variable. The primary outcome was extended LOS (>4 days). Secondary outcomes included mortality, acute kidney injury (AKI), major postoperative complications during the admission period, and readmission within 30 days. The primary analysis was a logistic regression with prespecified covariates: age, sex, surgical service, and the Memorial Sloan Kettering-Frailty Index. In an exploratory analysis, lasso regression was used to select covariates from a list of 4160 candidate variables. RESULTS: This study included 3796 patients with a median preoperative glucose of 104 mg/dL (interquartile range: 93-125). Higher preoperative glucose was univariately associated with increased odds of LOS > 4 days (odds ratio [OR]: 1.45, 95% confidence interval [CI]: 1.22-1.73), with similar results for AKI, readmission, and mortality. Adjustment for confounders eliminated these associations for LOS (OR: 0.97 [95% CI: 0.80-1.18]) and attenuated all other glucose-outcome associations. Lasso regression gave comparable results to the primary analysis. Using the upper bound of the respective 95% confidence interval, we estimated that, at best, successful reduction of elevated preoperative glucose would reduce the risk of LOS > 4 days, 30-day major complication, and 30-day mortality by 4%, 0.5%, and 1.3%, respectively. CONCLUSIONS: Poor outcomes following cancer surgery in older adults with elevated glucose are most likely related to poorer overall health in these patients rather than a direct causal effect of glucose. Aggressive glycemic management in the preoperative period has very limited potential benefits and is therefore unwarranted.

Independent validation of a pre-specified four-kallikrein marker model for prediction of adverse pathology and biochemical recurrence.

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.

De Novo Urinary Storage Symptoms Are Common after Radical Prostatectomy: Incidence, Natural History and Predictors.

PURPOSE: After radical prostatectomy (RP), clinical complaints of new onset storage symptoms may be related to anastomotic strictures or may accommodate for stress urinary incontinence; however, a subgroup of men will experience de novo storage symptoms in the absence of stricture or stress urinary incontinence. As therapies for overactive bladder have improved, we sought to assess the prevalence, natural history and risk factors of de novo storage dysfunction in continent men. MATERIALS AND METHODS: We retrospectively analyzed urinary symptom questionnaires completed by patients who were continent prior to RP and did not have postoperative anastomotic strictures at our institution from 2002 to 2019. De novo storage dysfunction, assessed as new onset or worsening urgency or frequency, was assessed at 6, 12, 18 and 24 months after RP, and association between it and patient and preoperative factors was determined. RESULTS: A total of 2,619 patients were included in the final analysis. An initial 34% of patients reported de novo storage symptoms at 6 months, which decreased to 26% at later followup. We found evidence that minimally invasive surgery and nonWhite race were associated with reporting worsening symptoms. The association between postoperative hematoma and worsening symptoms was less conclusive but was of clear clinical relevance (OR 3.15; 95% CI 1.04, 9.54; p=0.042). CONCLUSIONS: A significant number of RP patients experience de novo storage symptoms. Patients who underwent minimally invasive surgery are at higher risk. At-risk patients should be counseled on the incidence of de novo storage symptoms and offered early treatment per overactive bladder guidelines.

Characterization of Symptoms after Radical Prostatectomy and Their Relation to Postoperative Complications.

PURPOSE: Many patients will experience symptoms in the initial days after radical prostatectomy (RP), but early patient-reported symptoms have not been well characterized. Our objective was to illustrate the pattern of symptoms experienced after RP and the relation of severe symptoms to postoperative complications. MATERIALS AND METHODS: In 2016, electronic patient-reported symptom monitoring began at our institution's ambulatory surgery center. We retrospectively reviewed patients treated with minimally invasive RP who were sent a daily questionnaire completed using a web interface until postoperative day 10. Severe symptoms automatically generate a "yellow alert," which messages the clinic, while very severe symptoms generate a "red alert," additionally prompting the patient to call. We summarized rates of moderate-to-very severe symptoms and fit local polynomial regressions. We compared rates of 30-day or 90-day complications (grade ≥2) based on the presence of alert symptoms. RESULTS: Of 2,266 men undergoing RP, 1,942 (86%) completed surveys. Among moderate-to-very severe symptom levels, pain (72%) and dyspnea (11%) were most common. Pain, nausea and dyspnea consistently decreased over time; fever and vomiting had a flat pattern. In patients experiencing red-alert symptoms, we observed a higher risk of 30-day complications, but rates were low and differences between groups were nonsignificant (2.9% vs 1.9%; difference 1.1%; 95% CI -1.3-3.5; p=0.3). Results were similar examining 90-day complications. CONCLUSIONS: While symptoms are common after RP, substantial improvements occur over the first 10 days. Severe or very severe symptoms conferred at most a small absolute increase in complication risk, which should be reassuring to patients and clinicians.

Clinically Significant Risk Thresholds in the Management of Primary Cutaneous Melanoma: A Survey of Melanoma Experts.

BACKGROUND: Risk-based thresholds to guide management are undefined in the treatment of primary cutaneous melanoma but are essential to advance the field from traditional stage-based treatment to more individualized care. METHODS: To estimate treatment risk thresholds, hypothetical clinical melanoma scenarios were developed and a stratified random sample was distributed to expert melanoma clinicians via an anonymous web-based survey. Scenarios provided a defined 5-year risk of recurrence and asked for recommendations regarding clinical follow-up, imaging, and adjuvant therapy. Marginal probability of response across the spectrum of 5-year recurrence risk was estimated. The risk at which 50% of respondents recommended a treatment was defined as the risk threshold. RESULTS: The overall response rate was 56% (89/159). Three separate multivariable models were constructed to estimate the recommendations for clinical follow-up more than twice/year, for surveillance cross-sectional imaging at least once/year, and for adjuvant therapy. A 36% 5-year risk of recurrence was identified as the threshold for recommending clinical follow-up more than twice/year. The thresholds for recommending cross-sectional imaging and adjuvant therapy were 30 and 59%, respectively. Thresholds varied with the age of the hypothetical patient: at younger ages they were constant but increased rapidly at ages 60 years and above. CONCLUSIONS: To our knowledge, these data provide the first estimates of clinically significant treatment thresholds for patients with cutaneous melanoma based on risk of recurrence. Future refinement and adoption of thresholds would permit assessment of the clinical utility of novel prognostic tools and represents an early step toward individualizing treatment recommendations.

The association between modifiable perioperative parameters and renal function after nephrectomy.

OBJECTIVE: To evaluate the association between intraoperative anaesthetic parameters, primarily intraoperative hypotension, and postoperative renal function in patients undergoing nephrectomy. PATIENTS AND METHODS: We reviewed data from 3240 consecutive patients who underwent nephrectomy between 2010 and 2018. Anaesthetic parameters evaluated included duration of hypotension, tachycardia, hypothermia, volatile anaesthetic use and mean arterial pressure in the post-anaesthesia care unit. Outcomes included acute kidney injury (AKI) and estimated glomerular filtration rate (eGFR) within the first year after nephrectomy. Associations between anaesthetic parameters and outcomes were evaluated with multivariable logistic regression and generalised estimating equation, respectively, adjusted for predictors of renal function after nephrectomy. RESULTS: Before nephrectomy, 677 (21%) patients had moderate-severe chronic kidney disease. A quarter of patients (n = 809) had postoperative AKI and 35% (n = 746) had Stage ≥3 chronic kidney disease 12-months after surgery. Only 12% of patients (n = 386) had >5 min of intraoperative hypotension. While not statistically significant, longer duration of intraoperative hypotension was associated with slightly higher rates of AKI (odds ratio [OR] per 10-min 1.14, 95% confidence interval [CI] 0.98, 1.32). Prolonged hypothermia was associated with increased rate of AKI (OR per 10-min 1.02, 95% CI 1.00, 1.04), and decreased eGFR (change in eGFR per 10-min -0.19, 95% CI -0.27, -0.12); however, these results have limited clinical significance. CONCLUSIONS: Under current practice, intraoperative anaesthetic parameters are tightly maintained, restricting the significance of their effect on postoperative renal function. Future studies should evaluate whether haemodynamic parameters during the early postoperative period, when they are monitored less frequently, are associated with renal functional outcome.

Predictors of Worsening Erectile Function in Men with Functional Erections Early After Radical Prostatectomy.

BACKGROUND: Prior studies suggest that men with good erectile function shortly after radical prostatectomy (RP) can subsequently have worsened erectile function. AIM: To determine the prevalence and predictors of early erectile function recovery post-RP and of worsening erectile function after initial erectile function recovery. METHODS: We retrospectively queried our institutional database. Men who underwent RP during 2008-2017 and who completed the International Index of Erectile Function erectile function domain both pre-RP and serially post-RP, constituted the population. Functional erections were defined as International Index of Erectile Function (IIEF)-6 erectile function domain scores ≥24. We analyzed factors predicting functional erections at 3 months post-RP as well as factors predicting a decrease in functional erections between 3 and 6 months, defined as ≥2-point drop in the erectile function domain. Multivariable logistic regression models were used to identify predictors of early erectile function recovery and also of subsequent decline. OUTCOMES: Erectile function recovery rates at 3 months post-RP and predictive factors; rates of erectile function decline between 3-6 months and associated predictors. RESULTS: Eligible patients comprised 1,655 men with median age of 62 (IQR 57, 67) years. Bilateral nerve-sparing (NS) surgery was performed in 71% of men, unilateral NS in 19%, and no NS in 10%. Of this population, 224 men (14%; 95% CI 12%, 15%) had functional erections at 3 months post-RP. On multivariable analysis, significant predictors of early erectile function recovery included: younger age (OR 0.93, P < .001), higher baseline erectile function domain score (OR 1.14, P < .001) and bilateral NS (OR 3.81, P = .002). The presence of diabetes (OR 0.43, P = .028) and a former smoking history (OR 0.63, P = .008; reference group: never smoker) was associated with the erectile dysfunction at 3 months post-RP. Of the men with early functional erections, 41% (95% CI 33%, 48%) had a ≥ 2-point decline in erectile function between 3 and 6 months. No factors were identified as predictors for this decline. CLINICAL IMPLICATIONS: Only a small proportion of men have functional erections at 3 months post-RP and a notable number of them will experience a decline in erectile function between 3 and 6 months. STRENGTHS AND LIMITATIONS: Strengths: large patient population and the use of validated questionnaire. LIMITATIONS: single-center retrospective study. CONCLUSION: A minority of men had functional erections 3 months post-RP, about half of whom had a decline in erectile function by month 6. We recommend appropriately counseling post-RP patients on the risk of such a decline in erectile function. Salter CA, Tin AL, Bernie HL, et al.

Morbidity of salvage radical prostatectomy: limited impact of the minimally invasive approach.

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.

Assessment of Patient-Reported Outcomes in Patients With Anal Squamous-Cell Cancer Undergoing Combined Modality Therapy.

BACKGROUND: There is limited knowledge on long-term bowel, sexual, and urinary function after combined modality therapy for anal squamous-cell cancer. OBJECTIVE: This study aimed to evaluate long-term changes in patients treated with combined modality. DESIGN: This was a retrospective study of prospectively collected patient-reported outcome surveys. SETTING: This study was conducted at a single institution. PATIENTS: There were 143 patients with stage I to III anal cancer who were treated with chemoradiation and had completed the survey. MAIN OUTCOME MEASURES: This study included patient-reported outcomes reflecting bowel, sexual, and urinary function. RESULTS: Thirty-nine percent of patients had major low anterior resection syndrome at baseline. Major low anterior resection syndrome remained stable (38%; 95% CI, 31%-46%) with no change over time (OR 0.95; 95% CI, 0.74-1.21; p = 0.7). Higher rates of major low anterior resection syndrome were observed for patients who had major low anterior resection syndrome at baseline (OR 20.7; 95% CI 4.70-91.3; p < 0.001) and for females (OR 2.14; 95% CI, 1.01-4.56; p = 0.047). On 5-point scales, we saw a nonsignificant increased level of sexual arousal during sexual activity after therapy for women (ß for 1 year = 0.15; 95% CI, -0.01 to 0.32; p = 0.072) and nonsignificant decreased confidence in getting and keeping an erection after therapy for men (ß for 1 year = -0.33; 95% CI, -0.66 to 0.00; p = 0.053). LIMITATIONS: This was a single-institution study and only patients who answered the questionnaire were included in the study. CONCLUSIONS: A significant proportion of patients have major low anterior resection syndrome at baseline and after successful treatment for anal cancer. Having major low anterior resection syndrome at baseline was the biggest predictor of having major low anterior resection syndrome after treatment. Bowel, sexual, and urinary function did not improve over time up to 2 years after end of treatment. Physicians should counsel their patients before treatment that baseline poor bowel function is a risk factor for posttreatment bowel dysfunction. See Video Abstract at http://links.lww.com/DCR/C29 .

Electronic Rapid Fitness Assessment Identifies Factors Associated with Adverse Early Postoperative Outcomes following Radical Cystectomy.

PURPOSE: Frailty is associated with adverse outcomes following radical cystectomy. Prospective tools to identify factors affecting outcomes are needed. We describe a novel electronic rapid fitness assessment to evaluate geriatric patients undergoing radical cystectomy. MATERIALS AND METHODS: Before undergoing radical cystectomy between February 2015 and February 2018, 80 patients older than age 75 years completed the electronic rapid fitness assessment and were perioperatively comanaged by the Geriatrics Service. Physical function and cognitive function over 12 domains were evaluated and an accumulated geriatric deficit score was compiled. Hospital length of stay, discharge disposition, unplanned intensive care unit admissions, urgent care visits, readmissions, complications and deaths were assessed. RESULTS: A total of 65 patients who underwent radical cystectomy for bladder cancer without concomitant procedures completed the assessment. Median age was 80 (77, 84) years and 52 (80%) were male. A higher proportion of patients with intensive care unit admission, urgent care visit and major complications had impairments identified within electronic rapid fitness assessment domains, including Timed Up and Go. Readmission rates were similar between patients with or without deficits identified. Higher accumulated geriatric deficit score was significantly associated with intensive care unit admission (p=0.035), death within 90 days (p=0.037) and discharge to other than home (p=0.0002). CONCLUSIONS: We demonstrated the feasibility of assessing fitness in patients older than 75 years undergoing radical cystectomy using a novel electronic fitness tool. Physical limitations and overall impairment corresponded to higher intensive care unit admission rates and adverse postoperative outcomes. Larger studies in less resourced environments are required to validate these findings.

Assessment of Frailty Can Guide Decision Making for Utilization of Sentinel Lymph Node Biopsy in Patients with Thick Melanoma.

BACKGROUND: Sentinel lymph node biopsy (SLNB) is often omitted in selected patients with advanced primary melanoma, although the justification/criteria for omission have been debated. OBJECTIVE: We sought to determine whether assessment of frailty could serve as an objective marker to guide selection for SLNB in patients with advanced primary melanoma. METHODS: Patients presenting with clinical stage IIC (ulcerated, > 4 mm Breslow thickness) cutaneous melanoma from January 1999 through June 2019 were included. Frailty was assessed using the Memorial Sloan Kettering Frailty Index (MSK FI), a composite score of functional status and medical comorbidities. Five-year melanoma-specific survival (MSS) and overall survival (OS) were estimated using Cox regression, and predictors of OS were identified using competing risk models. RESULTS: MSS did not differ between patients who did (n = 451) or did not undergo SLNB (n = 179) [63.2% vs. 65.0%, p = 0.14]; however, omission of SLNB was associated with decreased 5-year OS (29% vs. 44%, p < 0.001). In a multivariable competing risk model, selection for SLNB omission was an independent predictor of death from non-melanoma causes (hazard ratio [HR] 1.7, 95% confidence interval [CI] 1.2-2.3, p < 0.001). After incorporation of the MSK FI score into the multivariable model in this subset, MSK FI (HR 2.4, 95% CI 1.5-4.1, p < 0.001), but not SLNB omission, was an independent predictor of poorer OS. CONCLUSION: We observed worse OS in patients with thick melanoma selected not to undergo SLNB, which was attributed to death due to non-melanoma causes. Formal assessment of frailty may provide an objective prognostic measure to guide selective use of SLNB in these patients.

Frailty based on the memorial Sloan Kettering Frailty Index is associated with surgical decision making, clinical trial participation, and overall survival among older women with ovarian cancer.

OBJECTIVES: To determine whether the Memorial Sloan Kettering Frailty Index (MSK-FI) is associated with decision-making in older women surgically treated for advanced-stage ovarian cancer. METHODS: We retrospectively applied the MSK-FI to women ≥70 years with newly diagnosed advanced-stage ovarian cancer surgically treated at our institution from 01/2001-05/2017. MSK-FI components, including 10 comorbidities and functional assessment, were extracted from medical records. The MSK-FI ranges from 0 to 11, with higher scores indicating greater frailty. The primary outcome was the association between frailty and rate of primary debulking surgery (PDS), for which a multivariable logistic regression was used, adjusted for stage and histology. RESULTS: We identified 430 women treated with PDS (n = 231, 54%) or neoadjuvant chemotherapy/interval debulking (n = 199, 46%) with complete data. MSK-FI score distribution was: "0", 95 patients (22%); "1", 172 (40%); "2", 89 (21%); and "3+", 74 (17%). More-frail patients were less likely to have undergone PDS (OR for a unit increase of MSK-FI: 0.64; 95%CI, 0.53-0.77; p < 0.0001). Grade 3+ complications and unintended intensive care admission occurred in 40 (9%) and 38 (9%) women, respectively, but were not associated with frailty (OR 1.21; 95%CI, 0.96-1.52; p = 0.11). More-frail patients were more likely to delay postoperative chemotherapy (non-linear association p = 0.009) and less likely to enroll in research (OR 0.84; 95%CI, 0.70-1.00; p = 0.049). Greater frailty was associated with poorer overall survival (HR 1.16; 95%CI, 1.05-1.30; p = 0.005). CONCLUSIONS: Frailty, as calculated by the MSK-FI, is strongly associated with treatment approach in older women with advanced ovarian cancer, suggesting objective or subjective correlates of the MSK-FI influence decision-making.

A pre-specified model based on four kallikrein markers in blood improves predictions of adverse pathology and biochemical recurrence after radical prostatectomy.

BACKGROUND: A pre-specified model based on four kallikrein markers in blood, commercially available as 4Kscore, predicts Gleason Grade (GG) 3 + 4 or higher prostate cancer on biopsy. However, sampling error and variation in pathology reporting may miss aggressive disease. METHODS: The 4Kscore was measured in cryopreserved blood from 2330 men obtained before prostatectomy at a single institution between 2002 and 2010. Adverse surgical pathology and biochemical recurrence (BCR) were pre-specified to be assessed in all men, biopsy GG 3 + 3, and 3 + 4. RESULTS: Adjusted for established clinical predictors, the 4Kscore was significantly associated with adverse pathology (OR 1.49; 95% CI 1.32, 1.67; p < 0.0001). Adding 4Kscore increased discrimination from (AUC) 0.672 to 0.718 and 0.644 to 0.659 within biopsy GG 3 + 3 and 3 + 4, respectively. Higher 4Kscore was associated with higher risk of BCR (HR 1.16, 95% CI 1.06, 1.26; p = 0.001). Adding 4Kscore improved the prediction of BCR (C-index 0.630-0.660) within GG 3 + 3, but not GG 3 + 4. CONCLUSIONS: The 4Kscore can help guide the clinical decision whether additional risk assessment-such as confirmatory biopsy-is needed to decide between active surveillance versus curative therapy. Evidence that the panel could influence management in biopsy GG 3 + 4 is less strong and requires further investigation.

Updating the International Index of Erectile Function: Evaluation of a Large Clinical Data Set.

INTRODUCTION: The International Index of Erectile Function (IIEF) is the predominant patient-reported outcomes instrument for assessing male sexual function. There are obvious problems with the use of the IIEF in the assessment of an individual patient, such as for men who use injections and men who do not engage in intercourse. AIM: The aim of the current study is to redesign the erectile function domain of the IIEF (IIEF6) to more accurately assess the individual patient. METHODS: In an observational study of men undergoing treatment for prostate cancer at a tertiary care institution, including 24,732 questionnaires completed by 6,780 individuals, IIEF6 scores were compared for patients using and not using erectile aids. Men not engaging in sexual intercourse were asked to describe the reason. MAIN OUTCOME MEASURE: The main outcome we were seeking was the IIEF6 scores. RESULTS: Mean scores before erectile aids items were added was 17.7 compared with predicted scores of 18.3 vs 16.7 if patients reported their function with vs without the use of aids. No intercourse was reported for 35% of surveys. Reasons given were lack of ability or confidence in 53%, lack of willing and available partner in 28%, "other" in 17% (including respondent's or partner's health issues, low libido, preference for nonpenetrative sex or for sex with men). Doubling the sum of the 3 nonintercourse IIEF6 questions had excellent properties (difference of 0.06, limits of agreement -3.10 to 3.22). CLINICAL IMPLICATIONS: Erectile function instruments must include items about erectile aids. Men who report that they have not attempted intercourse should not be assumed to have erectile dysfunction, but should be asked the reason why. For men who report lack of opportunity or preference for intercourse, the score of the 3 nonintercourse IIEF6 questions should be doubled. STRENGTHS & LIMITATIONS: This is a large study of patients in a real-world setting. Although the study only includes radical prostatectomy patients, and although the study cohort is not fully representative of the US prostate cancer population as a whole, these issues would not affect the key findings. CONCLUSION: The IIEF6 can be redesigned to better assess the individual patient. Vickers AJ, Tin AL, Singh K, et al.

Extensive disease among potential candidates for hemi-ablative focal therapy for prostate cancer.

OBJECTIVE: To examine a set of proposed eligibility factors for hemi-ablative focal therapy in prostate cancer and to determine the likelihood of residual extensive disease. METHODS: We retrospectively analyzed data from 98 patients with unilateral prostate cancer on biopsy with detailed tumor maps from whole-mount slides and preoperative magnetic resonance imaging data. These patients met the focal therapy consensus meeting inclusion criteria (prostate-specific antigen <15 ng/mL, clinical stage T1c-T2a and Gleason score 3 + 3 or 3 + 4 on needle biopsy), and underwent radical prostatectomy between 2000 and 2014. Extensive disease was defined as having Gleason pattern 4/5 in bilateral lobes, any extraprostatic extension, seminal vesicle invasion or lymph node invasion. Both lobes of the prostate were scored on magnetic resonance imaging. Preoperative characteristics including biopsy and magnetic resonance imaging data were used to predict extensive disease. RESULTS: Among our cohort of 98 patients, 40% (95% CI 30-50%) had extensive disease. A total of 33% (95% CI 24-43%) had Gleason pattern 4/5 in both lobes with a median Gleason pattern 4/5 tumor volume in the biopsy negative lobe of 0.06 cm3 , 17 patients had pathological tumor stage ≥3 and one patient had lymph node invasion. CONCLUSIONS: An important number of patients meeting the focal therapy consensus meeting inclusion criteria can present extensive disease. Further studies using targeted biopsies might provide more accurate information about the selection of focal therapy candidates.
