Critical care therapy and in-hospital mortality after radical nephroureterectomy for nonmetastatic upper urinary tract carcinoma.

BACKGROUND: Use of critical care therapies (CCT), that include invasive mechanical ventilation (IMV), total parenteral nutrition (TPN) and other modalities are unknown after radical nephroureterectomy (RNU) for upper urinary tract carcinoma (UUTC). Their relationship with in-hospital mortality is also unknown. METHODS: Within the National Inpatient Sample (2008-2019), we identified non-metastatic UUTC patients treated with RNU. Multivariable logistic regression models were used. RESULTS: Of 8,995 patients, 375 (4.2%) received CCT and 82 (0.9%) experienced in-hospital mortality. Of CCT modalities, 215 (2.4%) received IMV and 139 (1.5%) TPN. Temporal CCT, IMV, and TPN trends very closely followed in-hospital mortality trends. Relative to historical UUTC patients (2008-2013), contemporary (2014-2019) patients exhibited lower CCT (Δ = 2.2%, P value < 0.0001), lower IMV (Δ = 1.4%, P < 0.0001), lower TPN (Δ = 2.2%, P < 0.0001), and lower in-hospital mortality (Δ = 0.4%, P = 0.03) rates. Of in-hospital mortalities, 52 out of 82 received CCT but 30 of 82 did not. Median age (> 72 years; odds ratio [OR] 1.4; P = 0.002) and Charlson comorbidity index ≥ 3 (OR 4.1; P < 0.001) and ≥ 1-2 (OR 1.7; P = 0.001) independently predicted overall higher CCT, IMV, TPN, and in-hospital mortality. CONCLUSION: After RNU, CCT rates parallels in-hospital mortality rates. CCT represents a 5 to 6-fold multiple of in-hospital mortality rate. In RNU patients, CCT rates are higher in older and sicker individuals. Lower CCT rates that are paralleled by lower in-hospital mortality may be interpreted as an indicator of improved quality of care. Ideally all in-hospital mortalities should be predated by CCT exposure.

Neoadjuvant chemotherapy before radical cystectomy in patients with organ-confined and non-organ-confined urothelial carcinoma.

INTRODUCTION: Neoadjuvant chemotherapy (NAC) before radical cystectomy (RC) is guideline-recommended in patients with cT2-T4N0M0 urothelial carcinoma of urinary bladder (UCUB). However, no population-based study validated the survival benefit of NAC recorded in clinical trials in a stage-specific fashion. We addressed this knowledge gap. METHODS: Within the Surveillance, Epidemiology, and End Results database (2007-2020), we identified patients with cT2-T4N0M0 UCUB treated with NAC before RC versus RC alone. Cumulative incidence plots and multivariable competing risks regression (CRR) models were fitted. Survival analyses were performed according to organ confined (OC: cT2N0M0) versus nonorgan confined stages (NOC: cT3-T4N0M0). RESULTS: Of 3,743 assessable patients, 1,020 (27%) underwent NAC versus 2,723 (73%) RC alone. NAC rates increased over time in OC stage (EAPC = 11.9%, P < 0.001) and NOC stage (EAPC = 8.6%, P < 0.001). In OC stage, cumulative incidence plots derived 5-year CSM was 15.6% in NAC and 19.9% in RC alone patients (P = 0.008). In multivariable CRR models, NAC independently predicted lower CSM (hazard ratio (HR): 0.74, P = 0.01). Similarly, in NOC stage, cumulative incidence plots derived 5-year CSM was 36.1% in NAC and 46.0% in RC alone patients (P = 0.01). In multivariable CRR models, NAC independently predicted lower CSM (HR: 0.66, P < 0.001). CONCLUSION: NAC is associated with improved CSM compared to RC alone, both in OC and NOC stages. Specifically, the magnitude of the protective NAC effect was greater in NOC than OC patients. Thus, NAC should always be administered in all eligible patients before RC.

Survival Rates in Trimodal Therapy Versus Radiotherapy in Urothelial Carcinoma of Urinary Bladder.

BACKGROUND AND OBJECTIVE: Trimodal therapy (TMT) provided significant survival advantage relative to external beam radiation therapy (EBRT) alone in prospective trials. However, the magnitude of survival benefit has not been validated in population-based studies. The objective of this study is to determine whether TMT is associated with lower cancer-specific mortality (CSM) rates relative to EBRT. METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified patients with cT2-T4aN0M0 urothelial carcinoma of urinary bladder (UCUB) treated with either TMT or EBRT. Cumulative incidence plots and multivariable competing risk regression (CRR) models addressed CSM after additional adjustment for other-cause mortality and standard covariates. The same methodology was repeated according to stage and age categories. KEY FINDINGS AND LIMITATIONS: Of 4471 patients, 3391 (76%) underwent TMT versus 1080 (24%) EBRT. TMT rates increased over time in the overall cohort (estimated annual percent change [EAPC]: 1.8%, p < 0.001) as well as in organ-confined (OC) stage (EAPC: 1.7%, p < 0.001), but not in non-organ-confined (NOC) stage (p = 0.051). In the overall cohort, 5-yr CSM rates were 43.6% in TMT versus 52.7% in EBRT. In multivariable CRR models, TMT was an independent predictor of lower CSM (hazard ratio [HR]: 0.76, p < 0.001). In OC patients, 5-yr CSM rates were 42.0% in TMT versus 51.9% in EBRT (p < 0.001). In multivariable CRR models, TMT was an independent predictor of lower CSM (HR: 0.74, p < 0.001). Conversely, in NOC patients, TMT did not achieve independent predictor status (p = 0.3). CONCLUSIONS AND CLINICAL IMPLICATIONS: In this population-based study, relative to EBRT, TMT is associated with lower CSM in OC stage, but not in NOC UCUB patients. PATIENT SUMMARY: In this report, we investigated the survival benefit of administering systemic chemotherapy in addition to radiotherapy in patients who are candidates for bladder-sparing strategies. We found that the combination of systemic chemotherapy and radiotherapy leads to improved cancer-specific survival compared with radiotherapy alone in patients with organ-confined urothelial carcinoma. We conclude that among patients who are candidates for bladder-sparing strategies, following transurethral resection, the combination of radiotherapy and chemotherapy (namely, trimodal therapy) should always be offered in those with organ-confined urothelial carcinoma.

Perioperative Complications and In-Hospital Mortality in Paraplegic Radical Cystectomy Patients.

OBJECTIVE: The aim of this study was to test for the association between paraplegia and perioperative complications as well as in-hospital mortality after radical cystectomy (RC) for non-metastatic bladder cancer. METHODS: Perioperative complications and in-hospital mortality were tabulated in RC patients with or without paraplegia in the National Inpatient Sample (2000-2019). RESULTS: Of 25,527 RC patients, 185 (0.7%) were paraplegic. Paraplegic RC patients were younger (≤70 years of age; 75 vs. 53%), more frequently female (28 vs. 19%), and more frequently harbored Charlson Comorbidity Index ≥3 (56 vs. 18%). Of paraplegic vs. non-paraplegic RC patients, 141 versus 15,112 (76 vs. 60%) experienced overall complications, 38 versus 2794 (21 vs. 11%) pulmonary complications, 36 versus 3525 (19 vs. 14%) genitourinary complications, 33 versus 3087 (18 vs. 12%) intraoperative complications, 21 versus 1035 (11 vs. 4%) infections, and 17 versus 1343 (9 vs. 5%) wound complications, while 62 versus 6267 (34 vs. 25%) received blood transfusions, 47 versus 3044 (25 vs. 12%) received critical care therapy (CCT), and intrahospital mortality was recorded in 13 versus 456 (7.0 vs. 1.8%) patients. In multivariable logistic regression models, paraplegic status independently predicted higher overall CCT use (odds ratio [OR] 2.1, p < 0.001) as well as fourfold higher in-hospital mortality (p < 0.001), higher infection rate (OR 2.5, p < 0.001), higher blood transfusion rate (OR 1.45, p = 0.009), and higher intraoperative (OR 1.56, p = 0.02), wound (OR 1.89, p = 0.01), and pulmonary (OR 1.72, p = 0.004) complication rates. CONCLUSION: Paraplegic patients contemplating RC should be counseled about fourfold higher risk of in-hospital mortality and higher rates of other untoward effects.

Mortality rates in radical cystectomy patients with bladder cancer after radiation therapy for prostate cancer.

OBJECTIVE: To conduct a population-based study examining cancer-specific mortality (CSM) and other-cause mortality (OCM) differences in patients with radiation-induced secondary bladder cancer (RT-BCa) vs those with primary bladder cancer (pBCa) undergoing radical cystectomy (RC). METHODS: Within the Surveillance, Epidemiology, and End Results database (2004-2020), we identified patients with T2-4N0-3M0 bladder cancer treated with RC, who had previously been treated with external beam radiation therapy (EBRT) or brachytherapy for prostate cancer, as well as patients with T2-4N0-3M0 pBCa treated with RC. Cumulative incidence plots and multivariable competing risks regression (CRR) models were used to assess CSM after additional adjustment for OCM. The same methodology was then repeated based on organ-confined (OC: T2N0M0) and non-organ-confined (NOC: T3-4 and/or N1-3) disease. RESULTS: Of 9957 RC patients, RT-BCa was identified in 347 (3%) compared with 9610 (97%) who had pBCa. In multivariable CRR models, no CSM differences were recorded in the overall comparison (P = 0.8), nor in sub-groups based on OC and NOC disease (P = 0.8 and 0.7, respectively). Conversely, multivariable CRR models identified RT-BCa as an independent predictor of 1.3-fold higher OCM in the overall cohort and of 1.5-fold higher OCM in those with NOC disease. In a sensitivity analysis of patients with NOC disease, EBRT was associated with higher OCM rates (hazard ratio 1.5). By contrast, OCM rates were not different in those with OC disease (P = 0.8). CONCLUSION: Our study showed that RC for RT-BCa was associated with similar CSM rates as RC for pBCa, regardless of disease stage. However, patients who had undergone EBRT exhibited significantly higher OCM in the NOC sub-group.

Life Expectancy in High-Grade Incidental Prostate Cancer Patients Versus Population-Based Controls According to Treatment Type.

OBJECTIVE: To quantify the differences in 5-year overall survival (OS) between high-grade (Gleason sum 8-10) incidental prostate cancer (IPCa) patients and age-matched male population-based controls, according to treatment type: no active versus active treatment. MATERIALS AND METHODS: We relied on the Surveillance, Epidemiology, and End Results (SEER) database (2004-2015) to identify not actively treated and actively treated high-grade IPCa patients. For each case, we simulated an age-matched male control (Monte Carlo simulation), relying on Social Security Administration Life Tables (2004-2020) with 5 years of follow-up. Additionally, we relied on Kaplan-Meier plots to display OS for each treatment type. Multivariable Cox regression models were fitted to predict overall mortality (OM). RESULTS: Of 564 high-grade IPCa patients, 345 (61%) were not actively treated versus 219 (39%) were actively treated, either with radical prostatectomy or radiotherapy. Median OS was 3 years for not actively treated high-grade IPCa patients, with OS difference at 5 years follow-up of 27% relative to their age-matched male population-based controls (37% vs. 64%). Median OS was 8 years for actively treated high-grade IPCa patients, with OS difference at 5 years follow-up of 6% relative to their age-matched male population-based controls (68% vs. 74%). In the multivariable Cox regression model, active treatment independently predicted lower OM (hazard ratio = 0.6; 95% confidence interval = 0.4-0.8; p < 0.001). CONCLUSION: Relative to Life Tables' derived age-matched male controls, not actively treated high-grade IPCa patients exhibit drastically worse OS than their actively treated counterparts. These observations may encourage clinicians to consider active treatment in newly diagnosed high-grade IPCa patients.

Adult Prostate Sarcoma: Demographics, Treatment Patterns, and Survival.

BACKGROUND: This study aimed to examine clinicopathologic characteristics, treatment patterns, and survival rates in a contemporary population-based cohort of adult prostate sarcoma patients. METHODS: In the Surveillance, Epidemiology, and End Results database (2004-2020), adult patients with prostate sarcoma were identified. Descriptive statistics, Kaplan-Meier analyses, smoothed cumulative incidence plots, and Cox regression models were used. RESULTS: Of 125 patients, 45 (36%) harbored leiomyosarcoma, 17 (14%) had rhabdomyosarcoma, 15 (12%) had stromal sarcoma, 17 (14%) had sarcoma not otherwise specified (NOS), and 31 (25%) had other sarcoma subtypes. Metastatic stage was most common in the rhabdomyosarcoma patients (44%) and least common in the leiomyosarcoma (21%) and stromal sarcoma (20%) patients. Most of the rhabdomyosarcoma patients received the combination of systemic and radiation therapy with (24%) or without radical surgery (35%), whereas most of the leiomyosarcoma and stromal sarcoma patients underwent radical surgery with (22 and 13%) or without (22 and 47%) radiation. In the overall population, the median overall survival was 27 months. The 5-years overall versus cancer-specific versus other-cause mortality rates were respectively 71 versus 58 versus 13%. In the multivariable Cox regression models, the highest overall mortality was exhibited by the patients with metastatic disease (hazard ratio [HR] 2.87; 95% confidence interval [CI] 1.55-5.31; p < 0.001) or unknown disease stage (HR 2.94; 95% CI 2.20-7.21; p = 0.019). Conversely, of all the histologic subtypes, only stromal sarcoma distinguished itself by lower overall mortality (HR 0.41; 95% CI 0.18-0.96; p = 0.039). CONCLUSIONS: Four major histologic subtypes were identified. Among most adult sarcoma patients, treatment patterns vary according to histology, from multimodal therapy to radical prostatectomy alone. These treatment differences reflect equally important heterogeneity in survival patterns.

Predictive factors of hemoglobin drop after robot-assisted radical prostatectomy: a single center prospective study.

Robotic surgery provides precise control, allowing for optimal dissection and cutting of tissues while minimizing bleeding. However, a significant drop in hemoglobin (Hb) after robot-assisted radical prostatectomy (RARP) is often recorded. The current study aimed to examine the postoperative Hb drop and its predictive factors in prostate cancer (PCa) patients who underwent RARP. From our tertiary care center's prospectively maintained database, all PCa patients who underwent RARP from January 2022 to January 2023 were identified. For each patient, baseline, anesthesiologic, and surgical characteristics, as well as blood samples before and after surgery, were collected. Multivariable linear and logistic regression models were fitted to investigate potential predictive factors of linear Hb drop or Hb drop ≥ 2 g/dl between preoperative and postoperative day (POD) one, after RARP. Overall, 110 RARP patients were enrolled. Considering the Hb, the median preoperative and POD1 values were 14.6 and 12.7 g/dl respectively (∆ = 1.9, p < 0.001); between POD2 and POD3, no statistically significant difference was recorded (12.4 vs 12.5 g/dl, ∆ = 0.1, p = 0.1). After multivariable analyses, age, BMI, prostate volume, nerve-sparing approach, anesthesia time, intraoperative fluids, intraoperative blood loss, and intraoperative diuresis did not show a statistically significant predictive value (all p > 0.05). The current prospective study showed a statistically significant Hb drop until POD1. After that, a quick stabilization of the Hb value was recorded. This reduction was not correlated with pre- and intraoperative variables. These observations might play an important role in postoperative inpatient RARP management, in both large and low-volume centers.

Inpatient palliative care in metastatic adrenocortical carcinoma: a retrospective analysis using the National Inpatient Sample database.

BACKGROUND: The use of inpatient palliative care (IPC) in advanced cancer patients represents a well-established guideline recommendation. This study examines the utilization rates and patterns of IPC among patients with metastatic adrenocortical carcinoma (mACC). METHODS: Relying on the Nationwide Inpatient Sample database (2007-2019), we tabulated IPC rates in mACC patients. Estimated annual percentage changes (EAPC) analyses as well as multivariable logistic regression models (MLRM) predicting IPC use were fitted. RESULTS: Of 2040 mACC patients, 238 (12%) received IPC. Overall, the rate of IPC increased from 3.7% to 19.1% between 2007 and 2019 (EAPC +9.6%, P=0.001). During the same period, in-hospital mortality remained unchanged from 12.1 to 13.8% (EAPC 0.1%; P=0.97). Younger age at admission (<60 years; MLRM OR=0.70, P=0.013), solitary metastatic site (OR=0.63; P=0.015), and non-brain metastases (OR=0.62; P=0.033) were all associated with lower IPC use. CONCLUSIONS: In mACC patients, IPC use has increased from a marginal 3.7% to a moderate annual value of 19.1% in the most recent study year. These rates were not driven by a concomitant increase in in-hospital mortality (12.1% to 13.8%; P=0.9). and may be interpreted as an improvement in quality of care. Despite this encouraging increase, some patient characteristics herald lower IPC use. In consequence, younger patients, those with solitary metastatic sites, and non-brain metastases should be carefully considered for IPC to decrease or completely reduce the IPC access barrier maximally.

The prostate-gland asymmetry affects the 3- and 12-month continence recovery after RARP in patients with small prostate glands: a single center study.

To test the impact of the prostate-gland asymmetry on continence rates, namely 3- and 12-month continence recovery, in prostate cancer (PCa) patients who underwent robot-assisted radical prostatectomy (RARP). Within our institutional database, RARP patients with complete preoperative MRI features and 12 months follow-up were enrolled (2021-2023). The population has been stratified according to the presence or absence of prostate-gland asymmetry (defined as the presence of median lobe or side lobe dominance). Multivariable logistic regression models (LRMs) predicting the continence rate at 3 and 12 months after RARP were fitted in the overall population. Subsequently, the LRMs were repeated in two subgroup analyses based on prostate size (≤ 40 vs > 40 ml). Overall, 248 consecutive RARP patients were included in the analyses. The rate of continence at 3 and 12 months was 69 and 72%, respectively. After multivariable LRM the bladder neck sparing approach (OR 3.15, 95% CI 1.68-6.09, p value < 0.001) and BMI (OR 0.90, 95% CI 0.82-0.97, p = 0.006) were independent predictors of recovery continence at 3 months. The prostate-gland asymmetry independently predicted lower continence rates at 3 (OR 0.33, 95% CI 0.13-0.83, p = 0.02) and 12 months (OR 0.31, 95% CI 0.10-0.90, p = 0.03) in patients with prostate size ≤ 40 ml. The presence of prostate lobe asymmetry negatively affected the recovery of 3- and 12-months continence in prostate glands ≤ 40 mL. These observations should be considered in the preoperative planning and counseling of RARP patients.

Adverse In-Hospital Outcomes after Radical Prostatectomy in Leukemia History Patients.

INTRODUCTION: Leukemia history affects some radical prostatectomy (RP) patients. Although its prevalence and effect as an adverse risk factor are well known in cardiac surgery, the number of RP patients with a leukemia history, as well as their rate of adverse in-hospital outcomes, are unknown. METHODS: We identified RP patients (National Inpatient Sample 2000-2019), stratified according to the presence or absence of a leukemia history. Descriptive analyses, propensity score matching (PSM, ratio 1:10), and multivariable logistic regression models were used. RESULTS: Of 259,939 RP patients, 416 (0.2%) had a leukemia history. Their proportion increased from 0.1 to 0.2% covering the study span (p < 0.01). Leukemia history patients were older (median age, 64 vs. 62 years, p < 0.001). After PSM for age, insurance status, ethnicity, pelvic lymph node dissection, and Charlson Comorbidity Index, leukemia history RP patients exhibited higher rates of acute kidney injury (<2.6 vs. 0.9%; Odds Ratio [OR] 2.0, p = 0.02), more frequently underwent dialysis (3.6 vs. 1.9%; OR 1.9, p = 0.03), and more frequently had a length of stay exceeding one week (4.8 vs. 2.5%; OR 2.0, p = 0.006). CONCLUSIONS: Although leukemia history RP patients are rare, their numbers have increased. Renal complications and extended hospital stays are more frequent in those individuals.

Race/Ethnicity Affects Access and Survival Differences After Neoadjuvant or Adjuvant Chemotherapy at Radical Cystectomy in Urothelial Carcinoma Patients.

INTRODUCTION: It is unknown whether race/ethnicity affects access and/or survival after neoadjuvant (NAC) or adjuvant chemotherapy (ADJ) at radical cystectomy (RC). We addressed these knowledge gaps. MATERIAL AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2007-2020), we identified NAC candidates (T2-T4N0M0) and ADJ candidates (T3-T4 and/or N1-3). We focused on the four most prevalent race/ethnicities: Caucasians, Hispanics, African American (AA), and Asian/Pacific Islanders (API). Multivariable logistic regression models (MLR) tested access to NAC and ADJ. Subsequently, within NAC-exposed patients, survival analyses consisting of Kaplan-Meier plots and multivariable Cox regression models addressed CSM according to race/ethnicity were fitted. We repeated the same methodology in ADJ-exposed patients. RESULTS: In 6418 NAC candidates, NAC was administered in 1011 (19.0%) Caucasians, 88 (21.0%) Hispanics, 65 (17.0%) AA, and 53 (18.0%) API. In MLR, AA exhibited lower access rates to NAC (OR 0.83, p = 0.04). In NAC-exposed patients, AA independently predicted higher CSM (HR 1.3, p < 0.001) and API independently predicted lower CSM (HR 0.83, p = 0.03). Similarly, in 5195 ADJ candidates, ADJ was administered to 1387 (33.0%) Caucasians, 100 (28.0%) Hispanics, 105 (29.0%) AA, and 90 (37.0%) API. In MLR, AA (OR 68, p = 0.003) and Hispanics (OR 0.69, p = 0.004) exhibited lower access rates to ADJ. In ADJ-exposed patients, AA independently predicted lower CSM (HR 1.32, p < 0.001), while API showed better CSM (HR 0.82, p = 0.01). CONCLUSION: Relative to Caucasians, AA are less likely to receive either NAC or ADJ. Moreover, relative to Caucasians, AA exhibit higher CSM even when treated with either NAC or ADJ.

Differences in life expectancy of adrenocortical carcinoma patients vs. age­ and sex-matched population controls.

PURPOSE: To quantify to what extent the 5-year overall survival (OS) of adrenocortical carcinoma (ACC) patients differs from age- and sex-matched population-based controls, especially when stage is considered. METHODS: We relied on the Surveillance, Epidemiology, and End Results database (2004-2020) to identify newly diagnosed (2004-2014) ACC patients. Subsequently, we compared OS between ACC patients relative to simulated age- and sex-matched controls (Monte Carlo simulation), according to Social Security Administration Life Tables (2004-2020). RESULTS: Of all 742 ACC patients, 301 (41%) harbored localized stage, 173 (23%) locally advanced stage, and 268 (36%) metastatic stage. At 5-years follow-up, ACC patients' OS was 33%. After stratification for stage, the 5-years OS was 55 vs. 31 vs. 8% in localized, locally advanced, and metastatic stages, respectively. Conversely, after Monte Carlo simulation of age- and sex-matched controls, OS at five-years was 93% in the entire simulated cohort vs. 94% in the simulated localized cohort vs. 92 and 92% in locally advanced and metastatic stage, respectively. The resulting differences in OS between ACC patients and age- and sex-matched population-based controls were 60 vs. 39 vs. 61 vs. 84% respectively in the overall cohort vs. localized vs. locally advanced vs. metastatic stage. CONCLUSION: The most pronounced life expectancy detriment (84%) was recorded in metastatic ACC followed by locally advanced ACC patients (61%). Unfortunately, even in patients with localized ACC, life expectancy was 39% lower than that of the general population. Therefore, regardless of stage, ACC diagnosis results in a very pronounced detriment in life expectancy relative to the general population.

The role of lipidic balance on erectile dysfunction in prostate cancer patients undergoing robotic surgery.

OBJECTIVE: New indices of dyslipidemia, such as the Atherogenic Index of Plasma (AIP) or Castelli Risk Index I and II (CR-I/II), have been tested to predict erectile dysfunction (ED). The aim of this study was to assess the role of these lipidic scores in predicting severe ED and erectile function (EF) worsening in patients who underwent robot-assisted radical prostatectomy (RARP). METHODS: Data from 1249 prostate cancer patients who underwent RARP at our single tertiary academic referral center from September 2021 to April 2023 were reviewed. RARP patients with a complete lipid panel were included in the final analysis. Two independent multivariable logistic regression models (LRMs) were fitted to identify predictors of ED severity and worsening in RARP patients. RESULTS: Among the 357 RARP patients, the median age was 70 (interquartile range [IQR]: 65-74), and the median BMI was 28.4 (IQR: 26-30.4). According to the preoperative IIEF5, 115 (32.2%), 86 (24.5%), 26 (7.3%), and 40 (11.2%) were mild, mild-moderate, moderate, and severe ED patients, respectively. After multivariable LRMs predicting severe ED, only the nerve-sparing (NS) approach (odds ratio [OR]: 0.09) as well as the preoperative IIEF5 score (OR: 0.32) were independent predictors (p < 0.001). After LRMs predicting EF worsening, only preoperative IIEF5 was an independent predictor (OR: 1.42, p < 0.001). CONCLUSION: The power of novel lipidic scores in predicting severe ED and EF worsening in RARP patients was low, and they should not be routinely applied as a screening method in this patient subgroup. Only preoperative IIEF5 and nerve-sparing approaches are relevant in EF prediction after RARP.

Adjuvant Systemic Therapy Improved Survival After Radical Nephroureterectomy for Upper Tract Urothelial Carcinoma.

BACKGROUND: The purpose of this study was to test for survival differences according to adjuvant chemotherapy (AC) status in radical nephroureterectomy (RNU) patients with pT2-T4 and/or N1-2 upper tract urothelial carcinoma (UTUC). PATIENTS AND METHODS: Within the Surveillance, Epidemiology, and End Results database (SEER, 2007-2020), patients with UTUC treated with AC versus RNU alone were identified. Kaplan-Meier plots and multivariable Cox regression models addressed cancer-specific mortality (CSM). RESULTS: Of 1995 patients with UTUC, 804 (40%) underwent AC versus 1191 (60%) RNU alone. AC rates increased from 36.1 to 57.0% over time in the overall cohort [estimated annual percentage changes (EAPC) ± 4.5%, p < 0.001]. The increase was from 28.8 to 50.0% in TanyN0 patients (EAPC ± 7.8%, p < 0.001) versus 50.0-70.9% in TanyN1-2 patients (EAPC ± 2.3%, p = 0.002). Within 698 patients harboring TanyN1-2 stage, median CSM was 31 months after AC versus 16 months in RNU alone (Δ = 15 months, p < 0.0001) and AC independently predicted lower CSM [hazard ratio (HR) 0.64; p < 0.001]. Similarly, within subgroup analyses according to stage, relative to RNU alone, AC independently predicted lower CSM in T2N1-2 (HR 0.49; p = 0.04), in T3N1-2 (HR 0.72; p = 0.015), and in T4N1-2 (HR 0.49, p < 0.001) patients. Conversely, in all TanyN0 as well as in all stage-specific subgroup analyses addressing N0 patients, AC did not affect CSM rates (all p > 0.05). CONCLUSIONS: In RNU patients, AC use is associated with significantly lower CSM in lymph-node-positive (N1-2) patients but not in lymph-node-negative patients (N0). The distinction between N1-2 and N0 regarding the effect of AC on CSM applied across all T stages from T2 to T4, inclusively.

Survival of Metastatic Urothelial Carcinoma of Urinary Bladder According to Number and Location of Visceral Metastases.

OBJECTIVE: To test the association between number as well as locations of organ-specific metastatic sites and overall survival (OS) in systhemic-therapy exposed metastatic urothelial carcinoma of urinary bladder (mUCUB) patients. METHODS: Within Surveillance, Epidemiology and End Results database (2010-2020), all systhemic therapy-exposed mUCUB patients were identified. Kaplan-Meier and multivariable Cox regression (CRM) models first addressed OS in patients according to number of metastatic organ-locations: solitary versus 2 versus 3 or more. Subsequently, separate analyses stratified according to location type were completed in patients with solitary metastatic organ-location as well as in patients with 2 metastatic organ-locations. RESULTS: Of 1,310 mUCUB, 1,069 (82%) harbored solitary metastatic organ-location versus 193 (15%) harbored 2 separate metastatic organ-locations versus 48 (3%) harbored 3 or more metastatic organ-locations. Median OS decreased with increasing number of metastatic organ-locations (solitary vs. 2 vs. 3 or more, P < .0001). In multivariable CRM, relative to solitary metastatic organ-location, 2 (HR: 1.57, 95 Confidence interval [CI], 1.33-1.85) as well as 3 or more (HR: 1.69, 95% CI, 1.23-2.31) metastatic organ-locations independently predicted higher overall mortality (OM) (P = .001). In patients with solitary metastatic organ-location, brain metastases independently predicted higher OM (HR 1.67; 95% CI, 1.05-2.67; P = .03) than other locations. In patients with 2 metastatic organ-locations, no differences in OM were recorded according to organ type location. CONCLUSION: In systemic therapy exposed mUCUB, number of metastatic organ-locations (solitary vs. 2 vs. 3 or more), independently predicted increasingly worse prognosis. In patients with solitary metastatic organ-location, brain purported worse prognosis than others.

Incidence, Characteristics and Survival Rates of Bladder Cancer after Rectosigmoid Cancer Radiation.

BACKGROUND: Historical external beam radiation therapy (EBRT) for rectosigmoid cancer (RCa) predisposed patients to an increased risk of secondary bladder cancer (BCa). However, no contemporary radiotherapy studies are available. We addressed this knowledge gap. MATERIALS AND METHODS: Within the Surveillance, Epidemiology, and End Results database (2000-2020), we identified non-metastatic RCa patients who either underwent radiotherapy (EBRT+) or did not (EBRT-). Cumulative incidence plots and multivariable competing risk regression models (CRR) were fitted to address rates of BCa after RCa. In the subgroup of BCa patients, the same methodology addressed BCa-specific mortality (BCSM) according to EBRT exposure status. RESULTS: Of the 188,658 non-metastatic RCa patients, 54,562 (29%) were EBRT+ vs. 134,096 (73%) who were EBRT-. In the cumulative incidence plots, the ten-year BCa rates were 0.7% in EBRT+ vs. 0.7% in EBRT- patients (p = 0.8). In the CRR, EBRT+ status was unrelated to BCa rates (multivariable HR: 1.1, p = 0.8). In the subgroup of 1416 patients with BCa after RCa, 443 (31%) were EBRT+ vs. 973 (69%) who were EBRT-. In the cumulative incidence plots, the ten-year BCSM rates were 10.6% in EBRT+ vs. 12.1% in EBRT- patients (p = 0.7). In the CRR, EBRT+ status was unrelated to subsequent BCSM rates (multivariable HR: 0.9, p = 0.9). CONCLUSION: Although historical EBRT for RCa predisposed patients to higher BCa rates, contemporary EBRT for RCa is not associated with increased subsequent BCa risk. Moreover, in patients with BCa after RCa, exposure to EBRT does not affect BCSM.
