Baseline neutrophil-to-eosinophil-ratio and outcome in metastatic clear-cell renal cell carcinoma treated with nivolumab or ipilimumab/nivolumab.

BACKGROUND AND PURPOSE: This study aims to evaluate neutrophil-to-eosinophil ratio (NER) as a prognostic and/or predictive biomarker in metastatic clear cell renal cell carcinoma (m-ccRCC) treated with nivolumab or ipilimumab/nivolumab. PATIENTS/MATERIALS AND METHODS: We performed a retrospective study on m-ccRCC patients treated with nivolumab or ipilimumab/nivolumab (2012-2022). Baseline NER was calculated and correlated with clinical outcomes: response rate (RR), progression free survival (PFS) and overall survival (OS). Corresponding transcriptomic data were analysed. RESULTS: We included 201 m-ccRCC patients, 76 treated with ipilimumab/nivolumab and 125 with nivolumab. Baseline NER was statistically significantly associated with International Metastatic RCC Database Consortium (IMDC) risk groups. Increased NER was associated with shorter PFS and OS in the total patient series and nivolumab-treated patients. In patients treated with ipilimumab/nivolumab, increased NER was only statistically significantly associated with shorter OS. The impact of baseline NER on PFS and OS was independent of IMDC risk stratification. No clear correlation was found between baseline NER and RECIST response or maximal tumour shrinkage. In two additional databases, NER was also associated with PFS and OS in first-line vascular-endothelial-growth-factor-receptor tyrosine-kinase-inhibitors (VEGFR-TKIs), but not to disease-free survival in the post-nephrectomy setting. Lower NER was associated with intratumoural molecular features possibly associated with better outcome on immune checkpoint inhibitors. INTERPRETATION: Lower baseline NER is associated with better PFS and OS, independent of IMDC risk score, in m-ccRCC patients treated with ipilimumab/nivolumab or nivolumab. It correlates with intratumoural molecular features possibly associated with better outcome on immune checkpoint inhibitors. The predictive power of this biomarker is probably limited and insufficient for patient selection.

Diabetes, Obesity, and Pathological Upstaging in Renal Cell Carcinoma: Results From a Large Multi-institutional Consortium.

PURPOSE: We sought to determine whether clinical risk factors and morphometric features on preoperative imaging can be utilized to identify those patients with cT1 tumors who are at higher risk of upstaging (pT3a). MATERIALS AND METHODS: We performed a retrospective international case-control study of consecutive patients treated surgically with radical or partial nephrectomy for nonmetastatic renal cell carcinoma (cT1 N0) conducted between January 2010 and December 2018. Multivariable logistic regression models were used to study associations of preoperative risk factors on pT3a pathological upstaging among all patients, as well as subsets with those with preoperative tumors ≤4 cm, renal nephrometry scores, tumors ≤4 cm with nephrometry scores, and clear cell histology. We also examined association with pT3a subsets (renal vein, sinus fat, perinephric fat). RESULTS: Among the 4,092 partial nephrectomy and 2,056 radical nephrectomy patients, pathological upstaging occurred in 4.9% and 23.3%, respectively. Among each group independent factors associated with pT3a upstaging were increasing preoperative tumor size, increasing age, and the presence of diabetes. Specifically, among partial nephrectomy subjects diabetes (OR=1.65; 95% CI 1.17, 2.29), male sex (OR=1.62; 95% CI 1.14, 2.33), and increasing BMI (OR=1.03; 95% CI 1.00, 1.05 per 1 unit BMI) were statistically associated with upstaging. Subset analyses identified hilar tumors as more likely to be upstaged (partial nephrectomy OR=1.91; 95% CI 1.12, 3.16; radical nephrectomy OR=2.16; 95% CI 1.44, 3.25). CONCLUSIONS: Diabetes and higher BMI were associated with pathological upstaging, as were preoperative tumor size, increased age, and male sex. Similarly, hilar tumors were frequently upstaged.

Concomitant vs Staged Therapeutic Inguinal Lymphadenectomy in Clinically Node Positive Penile Squamous Cell Carcinoma: Does It Make a Difference?

PURPOSE: Inguinal lymph node dissection within 3 months of primary tumor resection in penile cancer has been associated with longer recurrence-free and cancer-specific survival. However, the optimal timing and effect of lymphadenectomy performed concurrently at the time of primary lesion management on oncologic outcomes in clinically lymph node positive penile squamous cell carcinoma remains unknown. MATERIALS AND METHODS: An international, multicenter cohort of 966 penile cancer cases was queried for penile squamous cell carcinoma management after the year 2000, clinically lymph node positive status, and performance of penile surgery and inguinal lymph node dissection. Cohorts were stratified as concomitant if inguinal lymph node dissection and penile surgery occurred on the same date or staged when inguinal lymph node dissection was performed after penile resection. Rates and patterns of penile squamous cell carcinoma recurrence were reported. Distant recurrence-free, cancer-specific, and overall survival were estimated using Kaplan-Meier analyses and groups compared with log-rank testing. RESULTS: Of 253 contemporary men with clinically lymph node positive penile squamous cell carcinoma, 96 (38%) underwent concomitant inguinal lymph node dissection and 157 (62%) had inguinal lymph node dissection performed in a staged manner. Penile cancer was most likely to recur distantly (19%) followed by in the groin (14%) or pelvis (5%). There were no differences in distant recurrence-free, cancer-specific, or overall survival between management strategies. Multivariable analysis adjusting for stage, treatment center, and perioperative chemoradiation also demonstrated no recurrence-free, cancer-specific, or overall survival benefit between management strategies. CONCLUSIONS: Inguinal lymph node dissection performed concurrently with excision of the penile tumor for clinically node positive penile squamous cell carcinoma is not associated with differences in recurrence-free, cancer-specific, or overall survival compared to staged lymph node dissection.

Screening programs for renal cell carcinoma: a systematic review by the EAU young academic urologists renal cancer working group.

PURPOSE: To systematically review studies focused on screening programs for renal cell carcinoma (RCC) and provide an exhaustive overview on their clinical impact, potential benefits, and harms. METHODS: A systematic review of the recent English-language literature was conducted according to the European Association of Urology guidelines and the PRISMA statement recommendations (PROSPERO ID: CRD42021283136) using the MEDLINE, Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov databases. Risk-of-bias assessment was performed according to the QUality In Prognosis Studies (QUIPS) tool. RESULTS: Overall, nine studies and one clinical trials were included. Eight studies reported results from RCC screening programs involving a total of 159 136 patients and four studies reported screening cost-analysis. The prevalence of RCC ranged between 0.02 and 0.22% and it was associated with the socio-demographic characteristics of the subjects; selection of the target population decreased, overall, the screening cost per diagnosis. CONCLUSIONS: Despite an increasing interest in RCC screening programs from patients and clinicians there is a relative lack of studies reporting the efficacy, cost-effectiveness, and the optimal modality for RCC screening. Targeting high-risk individuals and/or combining detection of RCC with other health checks represent pragmatic options to improve the cost-effectiveness and reduce the potential harms of RCC screening.

Clinicopathological predictors of finding additional inguinal lymph node metastases in penile cancer patients after positive dynamic sentinel node biopsy: a European multicentre evaluation.

OBJECTIVE: To develop a predictive model for additional inguinal lymph node metastases (LNM) at inguinal lymph node dissection (ILND) after positive dynamic sentinel node biopsy (DSNB) using DSNB characteristics to identify a patient group in which ILND might be omitted. PATIENTS AND METHODS: We conducted a retrospective study of 407 inguinal basins with a positive DSNB in penile cancer patients who underwent subsequent ILND from seven European centres. From the histopathology reports, the number of positive and negative lymph nodes, presence of extranodal extension and size of the metastasis were recorded. Using bootstrapped logistic regression, variables were selected for the clinical prediction model based on the optimization of Akaike's information criterion. The area under the curve (AUC) of the receiver-operating characteristic curve was calculated for the resulting model. Decision curve analysis (DCA) was used to evaluate the clinical utility of the model. RESULTS: Of the positive DSNBs, 64 (16%) harboured additional LNM at ILND. Number of positive nodes at positive DSNB (odds ratio [OR] 2.19, 95% confidence interval (CI) 1.17-4.00; P = 0.01) and largest metastasis size in mm (OR 1.06, 95% CI 1.03-1.10; P = 0.001) were selected for the clinical prediction model. The AUC was 0.67 (95% CI 0.60-0.74). The DCA showed no clinical benefit of using the clinical prediction model. CONCLUSION: A small but clinically important group of basins harbour additional LNM at completion ILND after positive DSNB. While DSNB characteristics were associated with additional LNM, they did not improve the selection of basins in which ILND could be omitted. Thus, completion ILND remains necessary in all basins with a positive DSNB.

Overall survival improvement in patients with metastatic clear-cell renal cell carcinoma between 2000 and 2020: a retrospective cohort study.

BACKGROUND: Only a few recent phase III trials with targeted therapies or immune checkpoint inhibitors (ICIs) in metastatic clear-cell renal cell carcinoma (m-ccRCC) demonstrated an overall survival (OS) benefit compared to standard of care. We aimed to study the evolution of OS since the start of systemic therapy from 2000 to 2020. PATIENTS AND METHODS: Retrospective study on all consecutively treated m-ccRCC patients in three Belgian hospitals starting with systemic therapy. The study outcome was OS since the start of systemic therapy. We used a univariable Cox model for OS with year of the start of therapy as a predictor, and a multivariable analysis including known prognostic factors. Linear and non-linear trends of time were tested. RESULTS: Five hundred patients were included. In a linear model, the HR for OS depending on the year of the start of therapy was 0.95 (95%CI 0.93-0.97; p < 0.0001), estimated for an increase with 1 year in time. In a non-linear model, OS started to improve from 2006 on, when vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) replaced interferon alfa (IFNa) as a standard of care and continued to increase steadily during the following years. On multivariable analysis, the year of the start of therapy remained an independent prognostic factor for OS. Two-year OS after the start of systemic therapy was 23%, 34%, 50% and 59% for patients who started treatment in 2000-2005, 2006-2011, 2012-2017, and 2018-2020, respectively. The five-year OS of the first three groups was 7%, 14% and 24%. The mean number of administered lines of therapy increased over time, with an incidence rate ratio of 1.07 (95%CI 1.05-1.08; p < 0.0001) per year increase for the period 2000-2016. CONCLUSION: OS of m-ccRCC patients has been improving significantly over the last 15 years since the introduction of VEGFR-TKIs and ICIs.

Patterns of Recurrence following Inguinal Lymph Node Dissection for Penile Cancer: Optimizing Surveillance Strategies.

PURPOSE: Our primary objective is to detail the incidence, site, and timing of penile squamous cell carcinoma (pSCC) recurrence after inguinal lymph node dissection (ILND). MATERIALS AND METHODS: We performed a retrospective analysis of 551 patients who underwent ILND for pSCC from 2000 to 2017. The primary outcome was pSCC recurrence after ILND. Recurrences were identified and stratified by site. Timing of recurrence was determined. Multivariable logistic regression analysis determined associations with recurrence. Multivariable Cox regression analysis determined associations with overall survival (OS). Sub-group analysis of the distant recurrences analyzed timing and OS by site of distant recurrence. RESULTS: After ILND pSCC recurred in 176 (31.9%) patients. Median time to recurrence was 10 months for distant recurrences, 12 for inguinal, 10.5 for pelvic, and 44.5 for local. Greater than 95% of distant, inguinal, and pelvic recurrences occurred within 48 months of ILND, versus 127 months for local recurrences. Post-ILND recurrence was associated with pN2 (OR 1.99, 95% CI 1.0-4.1), and pN3 (OR 7.2, 95% CI 4.0-13.7). Patients who had local recurrence had similar OS to those without (HR 1.5, 95% CI 0.6-3.8), and worse OS was identified in patients with inguinal (HR 4.5, 95% CI 2.8-7.1), pelvic (HR 2.6, 95% CI 1.5-4.5), or distant (HR 4.0, 95% CI 2.7-5.8) recurrences. Patients with lung recurrences had worse OS than other sites (HR 2.2, 95% CI 1.1-4.3). CONCLUSIONS: Of the patients 31.9% had post-ILND recurrence associated with high pN staging. Greater than 95% of distant, inguinal, and pelvic recurrences occurred within 48 months, suggesting surveillance beyond this is low yield. Local recurrences occurred over a longer timeline, emphasizing necessity of long-term surveillance of the primary site.

Predictors of local recurrence and its impact on survival after glansectomy for penile cancer: time to challenge the dogma?

OBJECTIVES: To identify predictive pathological factors for local recurrence (LR) and to study the impact of LR on survival in patients treated with glansectomy for penile squamous cell carcinoma (pSCC). PATIENTS AND METHODS: We retrospectively studied patients treated with glansectomy at international, high-volume reference centres. We analysed histopathological predictors of LR, stratified patients into risk groups based on the number of risk factors present, and studied the impact of LR on survival outcomes using Kaplan-Meier survival analysis and stepwise Cox proportional hazards regression models. Subsequently, we performed sensitivity analyses excluding margin-positive cases, pT3 disease, and cN+ disease, or all of these factors. RESULTS: Across nine institutions, 897 patients were included, of whom 94 experienced LR. On multivariable analysis, presence of high-grade disease and pT3 stage were independent predictors of LR. LR-free survival rates significantly differed according to the number of risk factors present, with a hazard ratio (HR) of 1.90 (95% confidence interval [CI] 1.17-3.07; P = 0.01) for the intermediate-risk group (one risk factor) and 6.11 (95% CI 3.47-10.77; P < 0.001) for the high-risk group (two risk factors), using the low-risk group (no risk factors) as reference. Patients who experienced LR had significantly worse overall survival (OS; HR 2.89, 95% CI 2.02-4.14; P < 0.001) and cancer-specific survival (CSS; HR 5.64, 95% CI 3.45-9.22; P < 0.001). LR (HR 3.82, 95% CI 2.14-6.8; P < 0.001), lymphovascular invasion and cN status were significant predictors of decreased CSS. LR remained a strong predictor of both OS and CSS in all sensitivity analyses. CONCLUSIONS: Pathological T3 stage and presence of high-grade disease were independent histopathological predictors of LR after glansectomy for primary pSCC, which allowed risk stratification into three groups with significantly different risk of developing LR. Additionally, LR is related to poor OS and CSS, indicating that LR is a manifestation of underlying aggressive disease and clearly challenging the dogma of using organ-sparing surgery whenever possible since survival is unaffected by higher LR rates.

Clinical, surgical, pathological and follow-up features of kidney cancer patients with Von Hippel-Lindau syndrome: novel insights from a large consortium.

PURPOSE: To investigate the natural history and follow-up after kidney tumor treatment of Von Hippel-Lindau (VHL) patients. MATERIALS AND METHODS: A multi-institutional European consortium of patients with VHL syndrome included 96 non-metastatic patients treated at 9 urological departments (1987-2018). Descriptive and survival analyses were performed. RESULTS AND LIMITATIONS: Median age at VHL diagnosis was 34 years (IQR 25-43). Two patients (2.1%) showed only renal manifestations at VHL diagnosis. Concomitant involvement of Central Nervous System (CNS) vs. pancreas vs. eyes vs. adrenal gland vs. others were present in 60.4 vs. 68.7 vs. 30.2 vs. 15.6 vs. 15.6% of patients, respectively. 45% of patients had both CNS and pancreatic diseases alongside kidney. The median interval between VHL diagnosis and renal cancer treatment resulted 79 months (IQR 0-132), and median index tumor size leading to treatment was 35.5 mm (IQR 28-60). Of resected malignant tumours, 73% were low grade. Of high-grade tumors, 61.1% were large > 4 cm. With a median follow-up of 8 years, clinical renal progression rate was 11.7% and 29.3% at 5 and 10 years, respectively. Overall mortality was 4% and 7.5% at 5 and 10 years, respectively. During the follow-up, 50% of patients did not receive a second active renal treatment. Finally, 25.3% of patients had CKD at last follow-up. CONCLUSIONS: Mean period between VHL diagnosis and renal cancer detection is roughly three years, with significant variability. Although, most renal tumors are small low-grade, clinical progression and mortality are not negligible. Moreover, kidney function represents a key issue in VHL patients.

Molecular underpinnings of glandular tropism in metastatic clear cell renal cell carcinoma: therapeutic implications.

BACKGROUND: Glandular metastases (GM) have been associated with improved survival in metastatic clear cell renal cell carcinoma (m-ccRCC). We aimed to molecularly characterize m-ccRCC with GM. MATERIAL AND METHODS: We performed a retrospective cohort study on all m-ccRCC patients with available tissue at our institution, diagnosed with metastatic disease from 2000 to 2019. We determined previously described angiogenesis- and immune-related gene expression signatures (GES) and ccrcc molecular subtypes through whole transcriptome RNA sequencing of primary tumors and metastases. We tested differences in GES and molecular subtypes across groups and studied overall (OS) and progression-free survival (PFS) using Kaplan-Meier survival analysis and Cox regression models. RESULTS: Primary tumors of patients who developed GM (n = 55) had higher IMmotion Angio (p < 0.001) and JAVELIN Angio (p = 0.003) GES as well as a higher proportion of angiogenic ccrcc2 molecular subtypes (p = 0.008) than primary tumors of patients with non-GM (n = 128). Metastatic lesions in glandular organs (n = 32) also had higher IMmotion Angio (p = 0.008) and JAVELIN Angio (p = 0.02) GES and were more frequently of the ccrcc2 molecular subtype (p = 0.03), compared to metastatic lesions in non-glandular organs in patients who did not develop any GM (n = 231), but not compared to metastatic lesions in non-glandular organs in patients who also developed GM (n = 18). Patients with GM had better OS (HR 0.49, p < 0.001) and PFS on first-line vascular endothelial growth factor receptor tyrosine kinase inhibitors (VEGFR-TKIs) (HR 0.64, p = 0.045) than patients with non-GM. PFS on first- or any-line immuno-oncology (IO) was not different. IMmotion Angio, JAVELIN Angio GES, and ccrcc2 molecular subtype were associated with better OS and PFS on first-line VEGFR-TKIs, but not PFS on first or any-line IO. CONCLUSIONS: Patients with m-ccRCC who develop GM are molecularly characterized by heightened angiogenesis, translating into better prognosis and better outcomes on VEGFR-TKIs, but not IO. Based on these findings, VEGFR-TKIs should be included in the first-line treatment of m-ccRCC patients with GM.

A risk calculator predicting recurrence in lymph node metastatic penile cancer.

OBJECTIVES: To develop and externally validate a risk calculator for prediction of any cancer recurrence in patients with penile squamous cell carcinoma (pSCC) and inguinal lymph node metastases (ILNM), as to date no validated prognostic tool is available for patients with pSCC and ILNM. PATIENTS AND METHODS: The development cohort included 234 patients from seven referral centres. The external validation cohort included 273 patients from two additional referral centres. Cox regression identified predictors of any recurrence, which were used to develop a risk calculator. The risk-calculator grouped the development and the validation cohorts according to the individual risk of any recurrence at 24 months (24m-R). Adjuvant treatment effects were tested on overall survival (OS) according to the derived tertiles, within the development and validation cohorts. RESULTS: Positive surgical margins, pN3 , and ILNM ratio were associated with higher recurrence rate. The 2-year OS rates were lower for patients with high (>37%) and intermediate (19-37%) compared to low (<19%) 24m-R risk of recurrence, for both the development (43% and 58% vs 83%, P < 0.001) and validation cohort (44% and 50% vs 85%, P < 0.001). Results were confirmed in the subgroup of patients who did not receive adjuvant treatment (P < 0.001), but not in patients who did receive adjuvant treatments in both the development and validation cohorts (P > 0.1). CONCLUSION: Adjuvant treatment planning is crucial in patients with pSCC with ILNM, where only weak evidence is available. The current tool proved to successfully stratify patients according to their individual risk, potentially allowing better tailoring of adjuvant treatments.

Whole-body diffusion-weighted magnetic resonance imaging for the detection of bone metastases and their prognostic impact in metastatic renal cell carcinoma patients treated with angiogenesis inhibitors.

Background: Metastatic renal cell carcinoma (mRCC) patients with bone metastases (BM) are at high risk for skeletal related events and have a poorer outcome when treated with vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKIs). Computed tomography (CT) lacks sensitivity to detect BM in mRCC. We aimed to determine the added value of whole body diffusion-weighted magnetic resonance imaging (WB-DWI/MRI) to CT for the detection of BM in mRCC and to estimate the prognostic impact of the number of BM in mRCC patients treated with VEGFR-TKIs.Material and methods: We conducted a prospective study including consecutive mRCC patients treated with a first-line VEGFR-TKI in the metastatic setting. All patients underwent a pretreatment thoracic-abdominal-pelvic CT and WB-DWI/MRI. CT and WB-DWI/MRI were compared for the detection of BM. The number of detected BM was correlated with response rate (RR), progression-free survival (PFS) and overall survival (OS) after start of the VEGFR-TKI.Results: Ninety-two patients were included. BM were found in 55% of the patients by WB-DWI/MRI and in 43% of the patients by CT (p = .003). Mean number of BM discovered per patient was 6.8 by WB-DWI/MRI versus 1.9 by CT (p = .006). The cutoff of ≤5 versus >5 BM on WB-DWI/MRI had the highest discriminative power for all outcome measures. Patients with >5 BM had a lower RR (10% versus 42%), more frequently early progressive disease (43% versus 13%, p = .003), shorter PFS (4 versus 10 months, p = .006) and shorter OS (10 versus 35 months, p < .0001) compared to patients with ≤5 BM.Conclusion: WB-DWI/MRI detects significantly more BM in mRCC patients than CT, allowing better estimation of the prognostic impact of BM in mRCC patients treated with VEGFR-TKIs. The prognostic impact should now be validated in patients treated with immune checkpoint inhibitors.

Impact of concomitant acid suppressive therapy on pazopanib efficacy and dose reductions in patients with metastatic renal cell carcinoma.

PURPOSE: The aim of this study was to investigate the impact of acid suppressive therapy on clinical efficacy and safety of pazopanib in patients with metastatic renal cell carcinoma (mRCC). METHODS: A single-center retrospective study was carried out. Charts of mRCC patients who received pazopanib as first-line treatment were reviewed and concomitant use of proton pump inhibitors (PPI) and histamine 2 receptor antagonists (H2RA) was studied. Two groups of patients were identified, namely patients receiving PPI/H2RA and patients without acid suppressive therapy. Both groups were compared with regard to progression free survival (PFS), overall survival (OS), tumor response, and time to dose reduction of pazopanib. RESULTS: Ninety-one patients were included. Median PFS was 8 months in the PPI/H2RA group vs. 7 months in the no PPI/H2RA group (hazard ratio (HR) 0.76 (95% confidence interval (CI) 0.42-1.35)), p = 0.35. Median OS was 27 months in the PPI/H2RA group vs. 23 months in the no PPI/H2RA group (HR 0.87 (95% CI 0.46-1.66)), p = 0.68. Mean tumor response was 17% (95% CI 8-25%) in the PPI/H2RA group vs. 11% (95% CI 0-21%) in the no PPI/H2RA group, p = 0.52. Median time to first dose reduction was 9 months in both subgroups (HR 1.25 (95% CI 0.65-2.39)), p = 0.51. Median time to second dose (< 600 mg) reduction was 17 months in the PPI/H2RA group vs. 7 months in the no PPI/H2RA group (HR 0.26 (95% CI 0.07-0.89)), p = 0.03. CONCLUSION: In this limited patient series, no evidence of a negative impact of PPI/H2RA on clinical outcome and time to first dose reduction was observed. These results suggest that PPI/H2RA might be considered, when there is a clinical need, in patients treated with pazopanib for mRCC. However, a prospective study is warranted to confirm these results.

Impact of the Standardization of Penile Cancer Care on the Quality of Care, Outcomes, and Academic-driven Centralization in a Single eUROGEN Referral Center.

BACKGROUND: Penile cancer (PeCa) represents a diagnostic and therapeutic challenge given the low patient volume, which may result in inadequate physician expertise and poor guideline adherence. Since 2015, we have developed a specific care pathway for PeCa in our tertiary referral center. OBJECTIVE: To evaluate the impact of a dedicated PeCa care pathway on patient management, the adequacy of pathological reporting, and oncological outcomes. DESIGN, SETTING, AND PARTICIPANTS: We retrospectively queried our institutional registry (S-66482) to identify patients who were surgically treated for PeCa between January 1989 and April 2022. The patient numbers were evaluated within a broader national context. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: We compared patient, surgery, tumor, and pathological data before and after 2015. Kaplan-Meier analysis was used to compare local and regional recurrence rates and cancer-specific survival (CSS). RESULTS AND LIMITATIONS: Overall, 313 patients were included, of whom 204 (65.1%) were surgically treated after 2015. The median number of patients treated yearly was significantly higher after 2015 (26 vs 5; p < 0.01). Patients treated after 2015 more frequently had no palpable lymph nodes at diagnosis, despite similar primary tumor stage. After adoption of the PeCa care pathway, organ-sparing surgery (OSS) was more commonly performed (79.9% vs 57.8%; p < 0.01) despite local staging being similar and without observing a significant increase in positive margins. Surgical staging in patients with European Association of Urology intermediate- or high-risk tumors was conducted more frequently after 2015 (90% vs 41%; p < 0.01). Pathology reporting was standardized, and there was more frequent reporting of p16 staining status (81.4% vs 8.3%; p < 0.01), lymphovascular invasion (93.8% vs 44.3%; p < 0.01), and perineural invasion (92.4% vs 44.3%; p < 0.01) following implementation. CONCLUSIONS: Implementation of a standardized care pathway for PeCa resulted in higher rates of OSS and pathological nodal staging and more complete pathology reports. Considering that these changes were associated with an increase in the number of patients treated, academic-driven centralization may play a role in optimizing the management of these patients. PATIENT SUMMARY: We evaluated the impact of a care pathway for patients with penile cancer on patient management, the completeness of pathology reporting, and cancer control. We found that implementation of this pathway was associated with an increase in the number of patients treated, higher rates of organ-sparing surgery and lymph node staging, and more complete pathology reports. Centralization of care may play a role in optimizing the management of penile cancer.

Cabozantinib Induces Isolated Hyperbilirubinemia in Renal Cell Carcinoma Patients carrying the UGT1A1*28 Polymorphism.

BACKGROUND: Genetic variants of UGT1A1, involved in glucuronidation and clearance of bilirubin, are associated with reduced bilirubin metabolization and drug-induced isolated hyperbilirubinemia. We studied the impact of the UGT1A1*28 polymorphism on drug-induced isolated hyperbilirubinemia in metastatic renal cell carcinoma patients treated with pazopanib, cabozantinib, and axitinib. METHODS: We genotyped the UGT1A1*28 TA6/TA6-TA6/TA7-TA7/TA7 polymorphism and correlated with median baseline, on-treatment and peak bilirubin levels during therapy, incidence of grade-1- or -2 (G1/2)-hyperbilirubinemia and time-to-G1-hyperbilirubinemia. RESULTS: Of the 66 patients treated with pazopanib, 29 received axitinib and 28 cabozantinib upon progression. Median baseline bilirubin was higher in TA7/TA7-carriers versus TA6/TA6+TA6/TA7-carriers at start of pazopanib (P < .0001), cabozantinib (P < .0001), and axitinib (P = .007). During pazopanib therapy, median bilirubin increased 1.4-fold in TA7/TA7+TA6/TA7-carriers but not in TA6/TA6-carriers. On cabozantinib, bilirubin increased 1.5-fold in TA7/TA7-carriers but not in TA6/TA6+TA6/TA7-carriers. Axitinib did not increase bilirubin in any genotype. Peak bilirubin in TA7/TA7- versus TA6/TA6+TA6/TA7-carriers was higher on pazopanib (P < .0001) or cabozantinib (P < .0001). With pazopanib, G1-hyperbilirubinemia occurred in 57% of TA7/TA7- and 12% of TA6/TA6+TA6/TA7-carriers (P = .0009) and G2-hyperbilirubinemia in 36% and 6% of the patients, respectively (P = .004). On cabozantinib, G1-hyperbilirubinemia occurred in 100% of TA7/TA7- and 5% of TA6/TA6+TA6/TA7-carriers (P < .0001) and G2-hyperbilirubinemia in 33% and 0% of the patients, respectively (P = .04). On axitinib, no correlation between the genotypes and G1/2-hyperbilirubinemia was observed. CONCLUSION: We validate the previously described impact of the UGT1A1*28 polymorphism on isolated bilirubin increase on pazopanib. We report for the first time that cabozantinib also interferes with UGT1A1 and causes isolated bilirubin increase.

Nutritional Supplement With Fermented Soy in Men With an Elevated Risk of Prostate Cancer and Negative Prostate Biopsies: General and Oncological Results From the Prospective PRAECAP Trial.

OBJECTIVE: To investigate the effect of a dietary supplement containing fermented soy on PSA, IPSS, changes in prostate volume and prostate cancer (PCa) development after a 6-month challenge in men at increased risk of PCa and negative previous biopsies. MATERIALS AND METHODS: Patients with an elevated risk of PCa, defined by either 1 of the following criteria: PSA >3 ng/mL, suspect lesion at digital rectal examination (DRE), suspect lesion at transrectal ultrasound (TRUS)/magnetic resonance imaging (MRI) and previous negative prostate biopsies (at least 8 cores) within 12 months before inclusion. Statistical analysis was carried out using a non-parametric 1-sided paired Wilcoxon rank sum test, chi-square test, and Fisher's exact test. RESULTS: In this trial, 94 patients were eligible for analysis. A PSA response was detected in 81% of the cases. In 25.8% (24/93) of patients, a decrease of at least 3 points on the IPSS was observed. The median prostate volume did not statistically change after 6 months (P = .908). Patients with PSA modulation required fewer investigations and had fewer positive biopsies (P <.001) and significantly fewer ISUP ≥3 lesions (P = .02). CONCLUSION: We observed a significantly lower PSA level after a 6-month challenge with a fermented soy-containing supplement, and an effect on IPSS in a subset of patients. Prescribing a fermented soy supplement in patients with an increased PCa risk could lead to a better selection of patients at real increased risk of having occult PCa.

A spatial architecture-embedding HLA signature to predict clinical response to immunotherapy in renal cell carcinoma.

An important challenge in the real-world management of patients with advanced clear-cell renal cell carcinoma (aRCC) is determining who might benefit from immune checkpoint blockade (ICB). Here we performed a comprehensive multiomics mapping of aRCC in the context of ICB treatment, involving discovery analyses in a real-world data cohort followed by validation in independent cohorts. We cross-connected bulk-tumor transcriptomes across >1,000 patients with validations at single-cell and spatial resolutions, revealing a patient-specific crosstalk between proinflammatory tumor-associated macrophages and (pre-)exhausted CD8+ T cells that was distinguished by a human leukocyte antigen repertoire with higher preference for tumoral neoantigens. A cross-omics machine learning pipeline helped derive a new tumor transcriptomic footprint of neoantigen-favoring human leukocyte antigen alleles. This machine learning signature correlated with positive outcome following ICB treatment in both real-world data and independent clinical cohorts. In experiments using the RENCA-tumor mouse model, CD40 agonism combined with PD1 blockade potentiated both proinflammatory tumor-associated macrophages and CD8+ T cells, thereby achieving maximal antitumor efficacy relative to other tested regimens. Thus, we present a new multiomics and spatial map of the immune-community architecture that drives ICB response in patients with aRCC.
