In systemic therapy trials, a decreasing neutrophil-to-lymphocyte ratio (NLR) after treatment for metastatic renal cell carcinoma (RCC) has been associated with improved oncologic outcomes. Paradoxically, for patients with localized RCC treated with upfront surgery the opposite effect has been reported. We thus aimed to evaluate NLR dynamics on localized RCC recurrence.Treatment naïve patients with localized RCC managed surgically between 2005 and 2020 were included. Preoperative NLR was calculated within 6-weeks prior to surgery and postoperative NLR was calculated between 4 and twelve-weeks after surgery. Patients were followed for disease recurrence, noting metastatic sites and postoperative infections. Cox regression were used to determine whether the relative change in postoperative NLR was associated with metastasis-free survival (MFS) and cancer-specific survival (CSS), adjusted for preoperative NLR.In the cohort of 3310 patients, 996 (30%) had postoperative NLR available. These patients generally had more advanced disease, with 100 developing metastases and 38 dying from kidney cancer. Median MFS follow-up was 4.4 years. Decreasing 2-month postoperative NLR was associated with non-statistically significant worse MFS and CSS (HR 0.79, 95% 0.50, 1.24, P = .3; HR 0.83, 95% C.I. 0.40, 1.73; P = .6). On sensitivity analysis, across all NLR measurements, with NLR as a time-dependent covariate, results were similar, with a declining NLR associated with adverse MFS (HR 0.85, 95% CI 0.69, 1.30, P-value = .10), though not meeting conventional levels of significance.In higher-risk localized RCC patients, postoperative NLR is not suitable as a biomarker for predicting recurrences.

BACKGROUND: Retrospective studies have shown the beneficial impact of geriatric comanagement (GERICO) on perioperative outcomes of older adults with cancer. We prospectively assessed the feasibility of perioperative GERICO for older adults with bladder cancer undergoing radical cystectomy. METHODS: We conducted a pilot study wherein all patients 75 years and older undergoing radical cystectomy between October 2019 and November 2020 were referred to the Geriatric Service preoperatively. Feasibility was defined according to the percentage of patients who received preoperative evaluation by the Geriatrics Service, who were followed for more than 80% of their inpatient days and who had their surgery rescheduled for logistical reasons. Urology advanced practice provider (APP) satisfaction with the program was measured via an 11-item survey. RESULTS: Sixty-six eligible patients underwent radical cystectomy in the stated time frame; 59 (89%; 95% confidence interval [CI], 79–97%) were referred to the Geriatric Service for evaluation. The median age of patients who had geriatric comanagement was 79 years; 40 (68%) were male. Forty-one patients (69%) were visited on at least 80% of the days in which they were not in the intensive care unit. No surgeries were rescheduled for logistical reasons. Nine of the 12 urology APPs (75%) responded to the survey; all nine “somewhat” or “strongly” agreed with statements indicating satisfaction with the program. CONCLUSION: Despite the challenges of the COVID-19 pandemic, we showed that perioperative GERICO is feasible. Fully powered prospective randomized controlled trials should be conducted to assess GERICO’s impact on perioperative outcomes of older adults with cancer.

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.

There is limited knowledge on long-term bowel, sexual, and urinary function after combined modality therapy for anal squamous-cell cancer.This study aimed to evaluate long-term changes in patients treated with combined modality.This was a retrospective study of prospectively collected patient-reported outcome surveys.This study was conducted at a single institution.There were 143 patients with stage I to III anal cancer who were treated with chemoradiation and had completed the survey.This study included patient-reported outcomes reflecting bowel, sexual, and urinary function.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; p0.001) 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 (β 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 (β for 1 year = -0.33; 95% CI, -0.66 to 0.00; p = 0.053).This was a single-institution study and only patients who answered the questionnaire were included in the study.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.

Las puntuaciones del síndrome de resección anterior baja mayor permanecieron estables (38 %; IC del 95%: 31 %, 46 %) sin cambios con el tiempo (OR 0,95, IC del 95%: 0,74, 1,21, p = 0,7). Se observaron tasas más altas de puntuaciones del síndrome de resección anterior baja mayor para los pacientes que tenían puntuaciones del síndrome de resección anterior baja mayor desde el inicio (OR 20,7; IC del 95%: 4,70; 91,3, p0,001) y para las mujeres (OR 2,14; IC del 95%: 1,01, 4,56; p = 0,047). En escalas de 5 puntos, observamos un aumento no significativo del nivel de excitación sexual durante la actividad sexual después de la terapia para las mujeres (β durante 1 año = 0,15; IC del 95%: -0,01, 0,32; p = 0,072) y una disminución no significativa de la confianza en lograr y mantener una erección después de la terapia para hombres (β para 1 año = -0,33; IC del 95%: -0,66, 0,00; p = 0,053).LIMITACIONES:Este es un estudio de una sola institución. Solo se incluyeron en el estudio los pacientes que contestaron el cuestionario.CONCLUSIONES:Una proporción significativa de pacientes tienen puntajes de síndrome de resección anterior muy bajos al inicio del estudio y después de un tratamiento exitoso para el cáncer anal. Tener puntajes de síndrome de resección anterior bajos importantes al inicio del estudio fue el predictor más importante de tener puntajes de síndrome de resección anterior bajos importantes después del tratamiento. La función intestinal, sexual y urinaria no mejoró con el tiempo hasta 2 años después de finalizar el tratamiento. Los médicos deben aconsejar a sus pacientes antes del tratamiento que la mala función intestinal inicial es un factor de riesgo para la disfunción intestinal posterior al tratamiento.

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.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.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.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.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).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.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.

A prostate-specific antigen density (PSAd) cutoff of 0.15 ng/ml/cc is a commonly recommended threshold to identify patients with negative prostate magnetic resonance imaging (MRI) who should proceed to a prostate biopsy. We were unable to find any study that explicitly examined the properties of this threshold compared with others.To investigate whether the 0.15 cutoff is justified for selecting patients at risk of harboring high-grade cancer (Gleason score ≥3 + 4) despite negative MRI.A cohort of 8974 prostate biopsies provided by the Prostate Biopsy Collaborative Group (PBCG) was included in the study.Locally weighted scatterplot smoothing was used to investigate whether there was a change in the risk of high-grade cancer around this value. We examined whether the use of this cutoff in patients with negative MRI corresponds to a reasonable threshold probability for a biopsy (defined as a 10% risk of high-grade disease). To do so, we applied the negative likelihood ratio of MRI, calculated from eight studies on prostate MRI, to the risk curve derived from the PBCG.There was no discontinuity in the risk of high-grade prostate cancer at a PSAd cutoff of 0.15. This cutoff corresponded to a probability of high-grade disease ranging from 2.6% to 10%, depending on MRI accuracy. Using 10% as threshold probability, the corresponding PSAd cutoff varied between 0.15 and 0.38, with the threshold increasing for greater MRI accuracy. Possible limitations include difference between studies on MRI and the use of ultrasound to measure prostate volume.The 0.15 cutoff to recommend prostate biopsies in patients with negative MRI is justified only under an extreme scenario of poor MRI properties. We recommend a value of at least ≥0.20. Our results suggest the need for future studies to look at how to best identify patients who need prostate biopsies despite negative MRI, likely by using individualized risk prediction.In this study, we investigated whether the commonly used prostate-specific antigen density cutoff of 0.15 is justified to identify patients with negative magnetic resonance imaging (MRI) who should proceed to a prostate biopsy. We found that this cutoff is appropriate only in case of very poor MRI quality, and a higher cutoff (≥0.20) should be used for the average MRI.

Pathologic nodal invasion at prostatectomy is frequently associated with persistently elevated prostate-specific antigen (PSA) and with increased risk of disease recurrence. Management strategies for these patients are poorly defined. We aimed to explore the long-term oncologic outcomes and patterns of disease progression.We included men treated between 2000 and 2017 who had lymph node invasion at radical prostatectomy and persistently detectable prostate-specific antigen post-prostatectomy. Postoperative imaging and management strategies were collated. Patterns of recurrence and probability of metastasis-free survival, prostate cancer-specific survival, and overall survival (OS) were assessed.Among our cohort of 253 patients, 126 developed metastasis. Twenty-five had a positive scan within 6 months of surgery; of these, 15 (60%) had a nodal metastasis, 10 (40%) had a bone metastasis, and 4 (16%) had local recurrence. For metastasis-free survival, 5- and 10-year probabilities were 52% (95% CI 45%, 58%) and 37% (95% CI 28%, 46%), respectively. For prostate cancer-specific survival, 5- and 10-year probabilities were 89% (95% CI 84%, 93%) and 67% (95% CI 57%, 76%), respectively. A total of 221 patients proceeded to hormonal deprivation treatment alone. Ten patients received postoperative radiotherapy.Biochemical persistence in patients with lymph node invasion is associated with high risk of disease progression and reduced prostate cancer-specific survival. Management was hindered by the limitation of imaging modalities utilized during the study period in accurately detecting residual disease. Novel molecular imaging may improve staging and help design a therapeutic strategy adapted to patients' specific needs.

PURPOSE To describe the development and implementation of a new digital health clinical tool (Gynecologic Survivorship Tool [GST]) for symptom management of women surgically treated for gynecologic cancer; to assess its feasibility; and to conduct a retrospective review of the data. MATERIALS AND METHODS The GST was developed on the basis of a comprehensive review of the literature, multidisciplinary expert opinion, and feedback from women with a history of gynecologic cancer. It is composed of 17 questions addressing six main categories—gynecologic health (abnormal bleeding/pain), lymphedema, vaginal/vulvar dryness, sexual health, menopause (hot flushes/sleep difficulties), and bowel/urinary issues. An electronic version using the Memorial Sloan Kettering Cancer Center Engage platform was piloted in two clinics for patients with endometrial or cervical cancer. Health information was generated into clinical summaries and identified concerns for actionable response. Associations of symptom and survey time point were assessed by longitudinal models using generalized estimating equations. RESULTS From January 1, 2019, to February 29, 2020, 3,357 GST assessments were assigned to 1,405 patients, with a 71% completion rate (90% within 5 minutes). Sixty-eight percent were performed at home via a patient portal, 32% at follow-ups using a clinic iPad. The most common symptoms were bowel problems, swelling/fluid, pain during examination, vaginal or vulvar dryness, and vaginal bleeding. Implementation challenges included improving patient compliance and ensuring that reports were reviewed by all clinical teams. We developed screening e-mails detailing patients whose assessments were due, planned training sessions for multidisciplinary teams, and incorporated feedback on methods for reviewing symptoms reports. CONCLUSION The GST demonstrated feasibility, a high completion rate, and minimal time commitment. It was an effective electronic reporting mechanism for patients, enabling the medical team to develop specific strategies for alleviating bothersome symptoms during follow-up.

Erectile dysfunction (ED) increases with age. Remarkably, the relationship between age and the risk of ED has only been described in crude categories, such as risk for men aged 50-59 yr, without taking comorbidities into account.To understand how the risk of patient-reported ED varies according to age and comorbidity status.This cross-sectional study included a cohort of 17 250 patients with prostate cancer who completed the International Index of Erectile Function erectile function domain (IIEF-EF) questionnaire before any prostate treatment.We created a logistic regression model to predict the probability of ED using age and comorbidities such as cardiovascular disease, diabetes, and hypertension as predictors. We used age as a nonlinear term to allow a curvilinear relationship between age and ED.The prevalence of patient-reported ED among men without any comorbidities increased from 10% to 79% from the age of 40 and 80 yr. The risk of ED increased sharply with comorbidity: the probability of ED for 50- and 75-yr-old individuals was 20% and 68% for healthy men, but 41% and 85% for those with hypertension, obesity, and diabetes. Men with several comorbidities have the same risk of ED as that of healthy men 15-25 yr older. Limitations include a healthier-than-average patient group and lack of information about some comorbidities and the severity of comorbidities.Our results allow us to better understand how the risk of ED changes with age and comorbidities. Further research should evaluate the impact of other risk factors not considered in the present study and should take risk factor severity into account.Our study shows how the probability of erectile dysfunction (ED) changes with increasing age, analyzed alone and when taking into account the presence of other risk factors for this condition (eg, diabetes, high blood pressure, and cardiovascular disease). Our results help in better understanding the probability of ED for men with and without comorbidities.

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.

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 to 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% C.I. 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). Five 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.

INTRODUCTION: After RP, clinical complaints of new onset storage symptoms may be related to anastomotic strictures or as accommodation 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 OAB have improved, we sought to assess the prevalence, natural history, and risk factors of de novo storage dysfunction in continent men. METHODS: We retrospectively analyzed urinary symptom questionnaires completed by patients who were continent prior to RP and did not have post-operative anastomotic strictures at our institution from 2002–2019. 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 determined. RESULTS: A total of 2619 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 follow-up. We found evidence that minimally invasive surgery and non-white race were associated with reporting worsening symptoms. The association between post-operative hematoma and worsening symptoms was less conclusive but was of clear clinical relevance (OR 3.15; 95% CI 1.04, 9.54; p-value = 0.042). CONCLUSION: A significant number of RP patients experience de novo storage symptoms. Patients who underwent MIS surgery are at higher risk. At risk patients should be counseled on the incidence of de novo storage symptoms and offered early treatment per OAB guidelines.

Background Advanced age and multiple comorbidities have been established as a risk factor for more severe disease and increased mortality among patients with COVID-19, yet the impact of frailty in patients with cancer 75 years and older who are admitted, remains unclear. Methods To better understand the clinical presentation and course of illness for this population, we conducted a chart review of patients with cancer age 75 and older who were admitted to a comprehensive cancer center within 72 h of a confirmed COVID-19 diagnosis over a three-month period (March 1, 2020-May 31, 2020). Frequency and proportion of characteristics were reported. We additionally assessed the association between frailty and 30-day mortality using univariable logistic regression. Results Our cohort consisted of 70 patients. We found evidence that increased frailty based on MSK-FI was associated with increased risk of 30-day mortality (OR 1.37, 95% CI 1.00, 1.87; p-value = 0.051), though this did not meet conventional levels of significance. Conclusion Our analysis showed evidence of some association between degree of frailty and 30-day survival among older patients with cancer aged ≥75 who were admitted with COVID-19 infection. This finding illustrates the importance of frailty screening in the care management of older patients with cancer and COVID-19.

Purpose Dyspnea related to chronic pulmonary disorders is difficult to manage. In this single-arm study, we evaluated feasibility and potential efficacy of a self-care breath training program to reduce dyspnea that persists despite standard treatments in patients with chronic lung disease. Methods Adult patients with a chronic pulmonary disorder and stable moderate dyspnea received one 30-min training on specific breathing techniques, followed by audio-guided at-home practice 15 min twice daily for 6 wk, supported with weekly telephone monitoring/coaching. The feasibility endpoints, Baseline and Transition Dyspnea Indexes, 6-min walk test, Hospital Anxiety and Depression Scale, and oxygen saturation at rest and exercise were evaluated at baseline and wk 6. Results Of the 23 patients enrolled over 2 yr, 19 completed the study. A majority (74%; 95% CI, 49%-91%) completed at least 75% of the home practice sessions. Significant objective improvements in physical performance, defined as distance walked, were observed after 6 wk of intervention. On average, patients walked significantly further in the 6-min walk test (59 ft; 95% CI, 18-99; P = .007). In addition, 53% reported clinically significant (20%, defined a priori) subjective improvement in the Transition Dyspnea Index, although the difference was not statistically significant (0.7; 95% CI, -0.8 to 2.3; P = .3). No significant differences were seen in the Hospital Anxiety and Depression Scale or oxygen saturation. Conclusions A low-burden, low-cost, self-care breath training program improved distance walked by patients with chronic dyspnea after 6 wk of home practice. Promising data suggest that a randomized trial of this breath training program is warranted.

e24014 Background: The stress from oncologic surgeries for older adults may lead to poor surgical outcomes. In this study, we aim to develop a MSK Surgery Stress Score to measure the complexity of surgery for these patients. The score could then be used for future analyses using datasets where patients undergoing a variety of procedures. Methods: This is a retrospective analysis of adults aged 75 and older who underwent elective cancer surgery in our institution with hospital length of stay of at least one day in 2015 to 2020. Based on surgery stress score developed by Haga et al., we explored various models including at least one or some of these variables as linear or non-linear terms: operation time, weight (kg), blood loss (cc), type of surgery, body mass index, and incision score. The primary outcome of interest evaluated was defined as the composite outcome of death within 90-day of surgery, readmission or emergency room visit or major complications (grade 3-5) within 30 days of surgery. We additionally explored models for a secondary outcome, where minor complications (grade 1-2) were included in the definition, and lastly, we looked at major complications alone as a tertiary outcome. For each of the model and outcomes, we used a logistic regression. We then used the logit transformation of the predicted probability to represent the proposed surgery stress score. Using this score, we evaluated the area under the curve (AUC) for each outcome. Results: In total, 1573 patients were included in the study. The median age was 80 (quartiles 77, 83) and just under half (49%) were male. The median (quartile) operation time was 181 minutes (115, 259), weight was 71 kg (62, 84), blood loss was 100 mL (50, 300), and just over (51%) of patient underwent an abdominopelvic procedure. The rate of 90-day mortality was 3.8%, while the rate of 30-day major complication, readmission and emergency room visit was 7.4%, 10% and 13%, respectively Furthermore, 21%, and 35% experienced primary, and secondary outcomes, respectively. Overall, 18 predictive models for each of the outcomes were developed and assessed. AUC for our different models ranged from 0.59 to 0.73 for the different definitions of our outcomes. Among the various models, the one defined using whether patients underwent an abdominopelvic procedure, incision score, operation time, weight, and blood loss (the latter two both included as non-linear terms) appeared to the front runner. Conclusions: We explored potential models to be used as the MSK Surgery Stress Score. Currently the model is being optimized by additional work. Following optimization of the model, future studies should validate this score in other cohorts of older surgical patients with cancer.

e24022 Background: With expansion of web-based geriatric assessment (GA), the aim of our study is to assess whether patients’ independency and time to complete electronic Rapid Fitness Assessment (eRFA), a web-based GA at our institution, is associated with frailty. Methods: Retrospective study of 3456 patients with cancer who underwent cancer surgery in 2015-2020 with hospital length of stay of 1+ days and completed the eRFA prior to surgery. Frailty was assessed by two methods: Memorial Sloan Kettering Frailty Index (MSK-FI, score 0-11) and accumulative geriatric deficits (AGD, score 0-13). In both measures, higher score is reflective of higher degree of frailty. Patient’s independency to complete the eRFA was self-reported (no help, some help, someone else). Time to complete the eRFA was captured by the system based on survey start time and submission time. Association between characteristics and patient’s independency to complete the eRFA were assessed using Kruskal Wallis test for continuous variable and Chi-square test for categorical variables. Analysis into time to complete the eRFA excluded surveys completed by someone else (n = 407), those completed in < 2 min (n = 1) or > 40 min (n = 82). Association between time to complete the eRFA and frailty was assessed using two separate linear regression models with frailty—MSK-FI and AGD, separately—as the outcome, and minutes to complete the eRFA as the predictor, in surveys completed with no help and some help, separately. Time to complete the eRFA was included in the model as a non-linear term with restricted cubic splines with knots at the tertiles. Results: Among our cohort, the median age at the time of survey completion was 78 (quartiles 75, 82), just under half (49%) of patients were male. Survey completion corresponded to 58% with no help, 30% with some help, and 12% by someone else. Independency in completing the eRFA was associated with younger age (median ages: no help 77, some help 80, someone else 80), and lower frailty (median AGD: no help 4, some help 6, someone else 8; median MSK-FI: no help 2, some help 3, someone else 3) (all p < 0.001). Longer time to complete the eRFA was associated with higher degree of frailty measured by MSK-FI and AGD (all non-linear association p < 0.001). For example, for surveys completed with no help in 5, 10, and 15 minutes, the estimated MSK-FI is 1.4 (95% CI 1.3, 1.6); 2.3 (95% CI 2.2, 2.4); and 2.3 (95% CI 2.1, 2.6), and the estimated AGD is 3.1 (95% CI 2.9, 3.3); 5.1 (95% CI 4.9, 5.4), and 5.1 (95% CI 4.7, 5.5). Conclusions: Patients who needed assistance or took a longer time to complete the assessment were more likely to have a higher degree of frailty. To avoid burdening the hospital, placing undue stress on patients, and possibly inaccurate responses, we should test solutions that may enhance the ability of frail patients to complete the eRFA faster and without assistance from others, such as by using voice assistants.

e24023 Background: Presence and severity of comorbid conditions impact surgical outcomes of older adults with cancer. The aim of our study is to evaluate the relationship between diabetes mellitus (DM), and preoperative HgbA1c (pHgbA1c) with frailty and adverse surgical outcomes among older adults with cancer. Methods: Retrospective study of patients aged 65 and older who underwent elective cancer surgery with at least one-day hospital stay in 2015-18 at our institution. For our primary aim, we assessed the association between DM and frailty, sociodemographic and clinical characteristics by reporting the characteristics stratified by presence of DM. Frailty was assessed using the Memorial Sloan Kettering Frailty Index (MSK-FI), which composes of 10 comorbidities and one functional component. This score ranges from 0-11, with higher score corresponding to greater frailty. Our secondary aim to assess the association between pHgbA1c and frailty was evaluated by a linear regression with pHgbA1c as the outcome and MSK-FI as the predictor. For our tertiary aim to assess the association between pHgbA1c and adverse surgical outcomes, we used a univariable logistic regression model with the outcome as the composite definition of 30-day readmission, 30-day emergency room visit, 30-day major complication, or 90-day mortality, and pHgbA1c as the predictor. We also used a multivariable logistics regression model, adjusting for age, gender, American Society of Anesthesiologist Performance Status (ASA-PS), and operation time.Analyses related to pHgbA1c excluded patients without pHgbA1c records. Results: Among 4417 patients, 1024 (23%) had DM and among those 403 (39%) had pHgbA1c values recorded. The results showed patients with DM were older, had higher ASA-PS, more comorbidities and higher MSK-FI scores than those without DM. Moreover, pHgbA1c was not found to be statistically associated with degree of frailty (β for one unit change in MSK-FI 0.11, 95% CI 0.00, 0.21; p = 0.057). Lastly, in both unadjusted and adjusted models pHgbA1c was not associated with adverse surgical outcomes (OR for both models, 0.99, 95% CI 0.83, 1.16, p = 0.9). Conclusions: In this cohort of patients whose pHgbA1c values were recorded, pHgbA1c was not associated with adverse surgical outcomes. Further studies are needed to confirm this study with more focus on perioperative care process of patients with DM and find cohorts whose pHgbA1c measurements can better predict frailty and adverse surgical outcomes.

To explore whether the association between preoperative neutrophil-to-lymphocyte ratio (NLR) elevation and worse survival is of use prognostically or merely a reflection of medical comorbidities in clear cell renal cell carcinoma (CC RCC).We identified 1970 patients treated at Memorial Sloan Kettering Cancer Center from 1998-2012 by partial or radical nephrectomy for non-metastatic CC RCC. NLR was calculated by dividing absolute neutrophil count by absolute lymphocyte count; both were obtained from preoperative complete blood count. Uni- and multivariable Cox proportional hazards regression, which included established prognostic variables, were used to test for association between NLR and recurrence-free (RFS), cancer-specific (CSS), and overall survival (OS).Univariate analysis identified elevated NLR as significantly associated with worse RFS, CSS, and OS (all p0.0001). However, upon multivariable analysis, elevated NLR was significantly associated with only worse OS (p0.0001). After adding markers of comorbidity that were significantly correlated with NLR elevation-higher American Society of Anesthesiologists class (p = 0.013), older age, and higher estimated glomerular filtration rate (both p0.0001)--into the multivariable model, NLR remained significantly associated with OS (p = 0.001). The addition of NLR into the prognostic model for OS did not increase Harrell's concordance index from 0.776.In our cohort, preoperative NLR elevation is associated with worse OS, but there was no significant association with RFS or CSS on multivariable analysis. Preoperative NLR does not add unique prognostic information for patients undergoing surgical resection of renal tumors.
