Differences in preoperative frailty assessment of surgical candidates by sex, age, and race. Surg Open Sci 2024; 19:172-177. [PMID: 38779040 PMCID: PMC11109462 DOI: 10.1016/j.sopen.2024.05.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2024] [Revised: 04/10/2024] [Accepted: 05/04/2024] [Indexed: 05/25/2024] Open
Abstract
Introduction Surgical decision-making often relies on a surgeon's subjective assessment of a patient's frailty status to undergo surgery. Certain patient demographics can influence subjective judgment when compared to validated objective assessments. In this study, we explore the relationship between subjective and objective frailty assessments according to patient age, sex, and race. Methods Patients were prospectively enrolled in urology, general surgery, and surgical oncology clinics. Using a visual analog scale (0-100), operating surgeons independently rated the patient's frailty status. Objective frailty was classified using the Fried Frailty Criteria ranging from 0 to 5. Multivariable proportional odds models were conducted to examine the potential association of factors with objective frailty, according to surgeon frailty rating. Subgroup analysis according to patient sex, race, and age was also performed. Results Seven male surgeons assessed 203 patients preoperatively with a median age of 65. A majority of patients were male (61 %), white (67 %), and 60 % and 40 % underwent urologic and general surgery/surgical oncology procedures respectively. Increased subjective surgeon rating (OR 1.69; p < 0.001) was significantly associated with the presence of objective frailty. On subgroup analysis, a higher magnitude of such association was observed more in females (OR 1.86; p = 0.0007), non-white (OR 1.84; p = 0.0019), and older (>60, OR 1.75; p = 0.0001) patients, compared to male (OR 1.45; p = 0.0243), non-white (OR 1.48; p = 0.0109) and patients under 60 (OR 1.47; p = 0.0823). Conclusion The surgeon's subjective assessment of frailty demonstrated tendencies to rate older, female, and non-white patients as frail; however, differences in patient sex, age, and race were not statistically significant.

Multi-ancestry genome-wide association study of kidney cancer identifies 63 susceptibility regions. Nat Genet 2024; 56:809-818. [PMID: 38671320 DOI: 10.1038/s41588-024-01725-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2023] [Accepted: 03/13/2024] [Indexed: 04/28/2024]
Abstract
Here, in a multi-ancestry genome-wide association study meta-analysis of kidney cancer (29,020 cases and 835,670 controls), we identified 63 susceptibility regions (50 novel) containing 108 independent risk loci. In analyses stratified by subtype, 52 regions (78 loci) were associated with clear cell renal cell carcinoma (RCC) and 6 regions (7 loci) with papillary RCC. Notably, we report a variant common in African ancestry individuals ( rs7629500 ) in the 3' untranslated region of VHL, nearly tripling clear cell RCC risk (odds ratio 2.72, 95% confidence interval 2.23-3.30). In cis-expression quantitative trait locus analyses, 48 variants from 34 regions point toward 83 candidate genes. Enrichment of hypoxia-inducible factor-binding sites underscores the importance of hypoxia-related mechanisms in kidney cancer. Our results advance understanding of the genetic architecture of kidney cancer, provide clues for functional investigation and enable generation of a validated polygenic risk score with an estimated area under the curve of 0.65 (0.74 including risk factors) among European ancestry individuals.

A missense SNP in the tumor suppressor SETD2 reduces H3K36me3 and mitotic spindle integrity in Drosophila. Genetics 2024; 226:iyae015. [PMID: 38290049 PMCID: PMC10990431 DOI: 10.1093/genetics/iyae015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2023] [Revised: 01/11/2024] [Accepted: 01/11/2024] [Indexed: 02/01/2024] Open
Abstract
Mutations in SETD2 are among the most prevalent drivers of renal cell carcinoma (RCC). We identified a novel single nucleotide polymorphism (SNP) in SETD2, E902Q, within a subset of RCC patients, which manifests as both an inherited or tumor-associated somatic mutation. To determine if the SNP is biologically functional, we used CRISPR-based genome editing to generate the orthologous mutation within the Drosophila melanogaster Set2 gene. In Drosophila, the homologous amino acid substitution, E741Q, reduces H3K36me3 levels comparable to Set2 knockdown, and this loss is rescued by reintroduction of a wild-type Set2 transgene. We similarly uncovered significant defects in spindle morphogenesis, consistent with the established role of SETD2 in methylating α-Tubulin during mitosis to regulate microtubule dynamics and maintain genome stability. These data indicate the Set2 E741Q SNP affects both histone methylation and spindle integrity. Moreover, this work further suggests the SETD2 E902Q SNP may hold clinical relevance.

The Selection for Cytoreductive Nephrectomy (SCREEN) Score: Improving Surgical Risk Stratification by Integrating Common Radiographic Features. Eur Urol Oncol 2024; 7:266-274. [PMID: 37442673 DOI: 10.1016/j.euo.2023.06.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 06/05/2023] [Accepted: 06/22/2023] [Indexed: 07/15/2023]
Abstract
BACKGROUND Careful patient selection is critical when considering cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC) but few studies have investigated the prognostic value of radiologic features that measure tumor burden. OBJECTIVE To develop a prognostic model to improve CN selection with integration of common radiologic features with known prognostic factors associated with mortality in the first year following surgery. DESIGN, SETTINGS, AND PARTICIPANTS Data were analyzed for consecutive patients with mRCC treated with upfront CN at five institutions from 2006 to 2017. Univariable and multivariable models were used to evaluate radiographic features and known risk factors for associations with overall survival. Relevant factors were used to create the SCREEN model and compared to the International mRCC Database Consortium (IMDC) model for predictive accuracy and clinical usefulness. RESULTS AND LIMITATIONS A total of 914 patients with mRCC were treated with upfront CN during the study period. Seven independently predictive variables were used in the SCREEN score: three or more metastatic sites, total metastatic tumor burden ≥5 cm, bone metastasis, systemic symptoms, low serum hemoglobin, low serum albumin, and neutrophil/lymphocyte ratio ≥4. Predictive accuracy measured as the area under the receiver operating characteristic curves was 0.76 for the SCREEN score and 0.55 for the IMDC model. Decision curve analysis showed that the SCREEN model was useful beyond the IMDC classifier for threshold first-year mortality probabilities between 15% and 70%. CONCLUSIONS The SCREEN score had higher predictive accuracy for first-year mortality compared to the IMDC scheme in a multi-institutional cohort and may be used to improve CN selection. PATIENT SUMMARY This study provides a model to improve selection of patients with metastatic kidney cancer who may benefit from surgical removal of the primary kidney tumor. We found that radiographic measurements of the tumor burden predicted the risk of death in the first year after surgery. The model can be used to improve decision-making by these patients and their physicians.

Interruptions in bladder cancer care during the COVID-19 public health emergency. Urol Oncol 2024; 42:116.e17-116.e21. [PMID: 38087711 DOI: 10.1016/j.urolonc.2023.11.010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2023] [Revised: 10/19/2023] [Accepted: 11/10/2023] [Indexed: 03/23/2024]
Abstract
BACKGROUND Academic and community urology centers participating in a pragmatic clinical trial in non-muscle-invasive bladder cancer completed monthly surveys assessing restrictions in aspects of bladder cancer care due to the COVID-19 Public Health Emergency. Our objective was to describe pandemic-related restrictions on bladder cancer care. METHODS We invited 32 sites participating in a multicenter pragmatic bladder cancer trial to complete monthly surveys distributed through REDCap beginning in May 2020. These surveys queried sites on whether they were experiencing restrictions in the use of elective surgery, transurethral resection of bladder tumors (TURBT), radical cystectomy, office cystoscopy, and intravesical bacillus Calmette-Guerin (BCG) availability. Responses were collated with descriptive statistics. RESULTS Of 32 eligible sites, 21 sites had at least a 50% monthly response rate over the study period and were included in the analysis. Elective surgery was paused at 76% of sites in May 2020, 48% of sites in January 2021, and 52% of sites in January 2022. Over those same periods, coinciding with COVID-19 incidence waves, TURBT was restricted at 10%, 14%, and 14% of sites, respectively, radical cystectomy was restricted at 10%, 14%, and 19% of sites, respectively, and cystoscopy was restricted at 33%, 0%, and 10% of sites, respectively. CONCLUSIONS Bladder cancer care was minimally restricted compared with more pronounced restrictions seen in general elective surgeries during the COVID-19 pandemic.

Abstract
Renal cell carcinoma (RCC) is occasionally associated with vena cava involvement. Despite recent advances in therapeutic modalities, the 5-year survival in this population continues to be poor. Therefore, further studies are required to better characterize this patient population, especially from the clinicopathologic standpoint. A comprehensive review of patients with RCC and vena cava involvement managed at our institution from 2014 to 2022 was performed. Multiple clinicopathologic parameters including follow-up were obtained. A total of 114 patients were identified. The mean patient age was 63 years (range: 30-84 years). The cohort consisted of 78/114 (68%) males and 36/114 (32%) females. The mean primary tumor size (excluding tumor thrombus) was 11 cm. The majority of tumors (104/114, 91%) were unifocal. Tumor stages were categorized as follows: pT3b (51/114, 44%), pT3c (52/114, 46%), and pT4 (11/114, 10%). Most of the tumors were clear cell RCC 89/114 (78%), although other more aggressive RCC subtypes were also present. Most tumors were WHO/ISUP grade 3 (44/114, 39%) or 4 (67/114, 59%) with sarcomatoid differentiation present in 39/67 (58%). Necrosis was present in 94/114 (82%) tumors. Twenty-three of 114 (20%) tumors were categorized as pM1 and the ipsilateral adrenal gland was the most common site of metastasis. Of the 91 patients categorized as pM, not applicable at nephrectomy, 42/91 (46%) subsequently developed metastasis, most frequently to the lung. Of all patients, only 16/114 (14%) had positive vascular margins and 7/114 (6%) had positive soft tissue margins despite having very advanced disease and a subset considered inoperable at other centers.

Impact of immunotherapy time-of-day infusion on survival and immunologic correlates in patients with metastatic renal cell carcinoma: a multicenter cohort analysis. J Immunother Cancer 2024; 12:e008011. [PMID: 38531662 DOI: 10.1136/jitc-2023-008011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 02/14/2024] [Indexed: 03/28/2024] Open
Abstract
BACKGROUND Recent studies have demonstrated that earlier time-of-day infusion of immune checkpoint inhibitors (ICIs) is associated with longer progression-free survival (PFS) and overall survival (OS) among patients with metastatic melanoma and non-small cell lung cancer. These data are in line with growing preclinical evidence that the adaptive immune response may be more effectively stimulated earlier in the day. We sought to determine the impact of time-of-day ICI infusions on outcomes among patients with metastatic renal cell carcinoma (mRCC). METHODS The treatment records of all patients with stage IV RCC who began ICI therapy within a multicenter academic hospital system between 2015 and 2020 were reviewed. The associations between the proportion of ICI infusions administered prior to noon (denoting morning infusions) and PFS and OS were evaluated using univariate and multivariable Cox proportional hazards regression. RESULTS In this study, 201 patients with mRCC (28% women) received ICIs and were followed over a median of 18 months (IQR 5-30). The median age at the time of ICI initiation was 63 years (IQR 56-70). 101 patients (50%) received ≥20% of their ICI infusions prior to noon (Group A) and 100 patients (50%) received <20% of infusions prior to noon (Group B). Across the two comparison groups, initial ICI agents consisted of nivolumab (58%), nivolumab plus ipilimumab (34%), and pembrolizumab (8%). On univariate analysis, patients in Group A had longer PFS and OS compared with those in Group B (PFS HR 0.67, 95% CI 0.48 to 0.94, Punivar=0.020; OS HR 0.57, 95% CI 0.34 to 0.95, Punivar=0.033). These significant findings persisted following multivariable adjustment for age, sex, performance status, International Metastatic RCC Database Consortium risk score, pretreatment lactate dehydrogenase, histology, and presence of bone, brain, and liver metastases (PFS HR 0.70, 95% CI 0.50 to 0.98, Pmultivar=0.040; OS HR 0.57, 95% CI 0.33 to 0.98, Pmultivar=0.043). CONCLUSIONS Patients with mRCC may benefit from earlier time-of-day receipt of ICIs. Our findings are consistent with established mechanisms of chrono-immunology, as well as with preceding analogous studies in melanoma and lung cancer. Additional prospective randomized trials are warranted.

Abstract
INTRODUCTION This study investigated the efficacy and safety of neoadjuvant chemotherapy (NAC) for locally advance penile squamous cell carcinoma (PSCC), for which current evidence is lacking. METHODS Included patients had locally advanced PSCC with clinical lymph node metastasis treated with at least one dose of NAC prior to planned consolidative lymphadenectomy. Objective response rates (ORR) were assessed using Response Evaluation Criteria in Solid Tumors (RECIST) v1.1. The primary and secondary outcomes were overall survival and progression-free survival, estimated by the Kaplan-Meier method. Treatment-related adverse events (trAEs) were graded per the Common Terminology Criteria for Adverse Events (CTCAE) v5.0. RESULTS 209 patients received NAC for locally advanced and clinically node-positive PSCC.The study population consisted of 7% of patients with stage II disease, 48% with stage III, and 45% with stage IV. Grade 2 TrAEs occurred in 35 (17%) patients, and no treatment related mortality was observed. 201 (97%) completed planned consolidative lymphadenectomy. During follow up, 106 (52.7%) patients expired, with a median OS of 37.0 months (95% CI 23.8-50.1), and median PFS of 26.0 months (95% CI 11.7-40.2). ORR was 57.2%, with 87 (43.2%) having partial response and 28 (13.9%) having a complete response. Patients with objective response to NAC had a longer median OS (73.0 vs 17.0 months, p < .01) compared to those who did not. The lymph-node pathologic complete response rate (ypN0) was 24.8% in the cohort. CONCLUSION NAC with lymphadenectomy for locally advanced PSCC is well tolerated and active to reduce the disease burden and improve long term survival outcomes.

Abstract
INTRODUCTION Baseline sarcopenia and postoperative changes in muscle mass are independently associated with overall survival (OS) in patients with metastatic renal cell carcinoma (mRCC) undergoing cytoreductive nephrectomy (CN). Here we examine the relationships between preoperative (baseline), postoperative changes in muscle quantity, and survival outcomes following CN as determined by linear segmentation, a clinic-friendly tool that rapidly estimates muscle mass. MATERIALS AND METHODS Our nephrectomy database was reviewed for patients with metastatic disease who underwent CN for RCC. Linear segmentation of the bilateral psoas/paraspinal muscles was completed for baseline imaging within 60 days of surgery and imaging 30 to 365 days postoperatively. Kruskal-Wallis for numerical and Fisher's exact test for categorical variables were used to test for differences between groups according to percent change in linear muscle index (LMI, cm2/m2). Multivariable Cox proportional hazards models evaluated associations between LMI percent change and cancer-specific (CSM) and all-cause mortality (ACM). Kaplan Meier curves estimated cancer-specific (CSS) and overall survival (OS). RESULTS From 2004-2020, 205 patients were included of whom 52 demonstrated stable LMI (25.4%; LMI change < 5% [0Δ]), 60 increase (29.3%; LMI +5% [+Δ]), and 92 decrease (44.9%; LMI -5% [-Δ]). Median time from baseline imaging to surgery was 18 days, and time from surgery to postoperative imaging was 133 days. Median CSS and OS were highest among patients with 0Δ LMI (CSS: 133.6 [0Δ] vs. 61.9 [+Δ] vs. 37.4 [-Δ] months; P = .0018 || OS: 67.2 [0Δ] vs. 54.8 [+Δ] vs. 29.5 [-Δ] months; P = .0007). Stable LMI was a protective factor for CSM (HR 0.48; P = .024) and ACM (HR 0.59; P = .040) on multivariable analysis. DISCUSSION Change in muscle mass after CN, as measured by the linear muscle segmentation technique, is independently associated with OS and CSS in patients following CN. Of note, lack of change was associated with longer survival.

2018 Leibovich prognostic model for renal cell carcinoma: Performance in a large population with special consideration of Black race. Cancer 2024; 130:453-466.

Abstract
BACKGROUND The 2018 Leibovich prognostic model for nonmetastatic renal cell carcinoma (RCC) combines clinical, surgical, and pathologic factors to predict progression-free survival (PFS) and cancer-specific survival (CSS) for patients with clear cell (ccRCC), papillary (pRCC), and chromophobe (chRCC) histology. Despite high accuracy, <1% of the original cohort was Black. Here, the authors examined this model in a large population with greater Black patient representation. METHODS By using a prospectively maintained RCC institutional database, patients were assigned Leibovich model risk scores. Survival outcomes included 5-year and 10-year PFS and CSS. Prognostic accuracy was determined using area under the curve (AUC) analysis and calibration plots. Black patient subanalyses were conducted. RESULTS In total, 657 (29%) of 2295 patients analyzed identified as Black. Declines in PFS and CSS were observed as scores increased. Discrimination for ccRCC was strong for PFS (AUC: 5-year PFS, 0.81; 10-year PFS, 0.78) and for CSS (AUC: 5-year CSS, 0.82; 10-year CSS, 0.74). The pRCC AUC for PFS was 0.74 at 5 years and 0.71 at 10 years; and the AUC for CSS was 0.74 at 5 years and 0.70 at 10 years. In chRCC, better performance was observed for CSS (AUC at 5 years, 0.75) than for PFS (AUC: 0.66 at 5 years; 0.55 at 10 years). Black patient subanalysis revealed similar-to-improved performance for ccRCC at 5 years (AUC: PFS, 0.79; CSS, 0.87). For pRCC, performance was lower for PFS (AUC at 5 years, 0.63) and was similar for CSS (AUC at 5 years, 0.77). Sample size limited Black patient 10-year and chRCC analyses. CONCLUSIONS The authors externally validated the 2018 Leibovich RCC prognostic model and found optimal performance for ccRCC, followed by pRCC, and then chRCC. Importantly, the results were consistent in this large representation of Black patients. PLAIN LANGUAGE SUMMARY In 2018, a model to predict survival in patients with renal cell carcinoma (kidney cancer) was introduced by Leibovich et al. This model has performed well; however, Black patients have been under-represented in examination of its performance. In this study, 657 Black patients (29%) were included, and the results were consistent. This work is important for making sure the model can be applied to all patient populations.

Abstract
OBJECTIVE To examine the performance of the Palacios et al [Aguilar Palacios D, Wilson B, Ascha M, et al. New baseline renal function after radical or partial nephrectomy: a simple and accurate predictive model. J Urol. 2021;205:1310-1320] post-nephrectomy future glomerular function rate (fGFR) equation in a diverse cohort using both the Chronic Kidney Disease Epidemiology (CKD-EPI) 2009 equation with race, used in the creation of the formula, as well as the CKD-EPI 2021 equation without race. METHODS Patients who underwent partial or radical nephrectomy for renal cell carcinoma from 2005-2021 were identified in our institutional database. Patients with creatinine values preoperatively and 3-12 months postoperatively were included. Correlation/bias/accuracy/precision of the fGFR equation (fGFR = 35+ [preoperative eGFR × 0.65] - 18 [if radical] - [age × 0.25] + 3 [if tumor >7 cm] - 2 [if diabetes]) with observed postoperative eGFR was determined by both the CKD-EPI-2021 and CKD-EPI 2009 equations. RESULTS A total of 1443 patients were analyzed. Seventy-one percent (1024) were White and 22.9% (331) were Black. Most underwent radical nephrectomy (60.3%). 40% T3-T4 renal cell carcinoma (RCC), with 14.8% of patients having M1 disease. Median observed vs predicted fGFR was 58.0 vs 58.7 mL/min/1.73 m2 for CKD-EPI 2021 and 56.0 vs 57.5 for CKD-EPI 2009. For the total cohort, the correlation/bias/accuracy/precision of the fGFR equation was 0.805/-0.5/81.7/7.9-9.0 for CKD-EPI 2021 and 0.809/-0.8/81.3/-8.1 to 8 for CKD-EPI 2009. In Black patients, fGFR equation demonstrated >75% accuracy with both CKD-EPI equations; however, accuracy was lower in black patients with the CKD-EPI2021 equation (76.1% vs 83.4%, P = .003). CONCLUSION The fGFR equation performed well in our large, diverse cohort, though accuracy was relatively lower when using CKD-EPI 2021 compared to CKD-EPI 2009.

[PMID: 37565840 DOI: 10.1002/cncr.34982] [Citation(s) in RCA: 8] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2023] [Revised: 06/08/2023] [Accepted: 06/12/2023] [Indexed: 08/12/2023]
Abstract
BACKGROUND Advanced penile squamous cell carcinoma (pSCC) is a rare and aggressive malignancy with limited success of immune-checkpoint inhibitors (ICIs). Approximately half of pSCC cases are associated with human papillomavirus (HPV) infection. METHODS Evaluation was done retrospectively of the landscape of somatic alterations and ICI-related biomarkers in pSCC by using the Caris Life Sciences data set with the aim to establish signatures for HPV-dependent oncogenesis. The pSCC tumors were analyzed by using next-generation sequencing (NGS) of DNA and RNA. Programmed death ligand 1 (PD-L1) expression was evaluated by immunohistochemistry (IHC). Microsatellite instability (MSI) was tested by fragment analysis, IHC (SP142; ≥1%), and NGS. Tumor mutational burden (TMB)-high was defined as ≥10 mutations/Mb. HPV16/18 status was determined by using whole-exome sequencing (WES) when available. Significance was adjusted for multiple comparisons (q value < .05). RESULTS NGS of the overall cohort (N = 108) revealed TP53 (46%), CDKN2A (26%), and PIK3CA (25%) to be the most common mutations. Overall, 51% of tumors were PD-L1+, 10.7% had high TMB, and 1.1% had mismatch repair-deficient (dMMR)/MSI-high status. Twenty-nine patients had their HPV status made available by WES (HPV16/18+, n = 13; HPV16/18-, n = 16). KMT2C mutations (33% vs. 0%) and FGF3 amplifications (30.8% vs. 0%) were specific to HPV16/18+ tumors, whereas CDKN2A mutations (0% vs. 37.5%) were exclusive to HPV16/18- tumors. TMB-high was exclusively found in the HPV16/18+ group (30.8%). The two groups had comparable PD-L1 and dMMR/MSI-H status. CONCLUSIONS In a large and comprehensive NGS-based evaluation of somatic alterations in pSCC, HPV16/18+ versus HPV16/18- pSCCs were molecularly distinct tumors. Our finding that TMB-high is exclusive to HPV16/18+ tumors requires confirmation in larger data sets. PLAIN LANGUAGE SUMMARY Penile squamous cell carcinoma (pSCC) is a rare and aggressive malignancy in the advanced setting, with poor prognosis and little success with immune-checkpoint inhibitors (ICIs) in an unselected patient approach. Human papillomavirus (HPV) infection is a known risk factor for pSCC; its impact on genomic tumor profiling is less defined. Using next-generation sequencing, we explored the genetic landscape and ICI-related biomarkers of pSCC and HPV-driven oncogenic molecular signatures. Our results indicate that HPV-positive and HPV-negative pSCCs are molecularly distinct tumors. Increased tumor mutational burden is associated with HPV-positive tumors, and could serve as a biomarker for predicting therapeutic response to ICI-based therapies. Our results support the growing literature indicating that HPV status in pSCC can be used to guide patient stratification in ICI-based clinical trials.

Creatinine to Cystatin-C Ratio in Renal Cell Carcinoma: A Clinically Pragmatic Prognostic Factor and Sarcopenia Biomarker. Oncologist 2023; 28:e1219-e1229. [PMID: 37540787 PMCID: PMC10712910 DOI: 10.1093/oncolo/oyad218] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 07/07/2023] [Indexed: 08/06/2023] Open
Abstract
INTRODUCTION Low creatinine to cystatin-C ratio (Cr/Cys-C) may be a biomarker for low-muscle mass. Furthermore, low Cr/Cys-C is associated with decreased overall survival (OS), but to date, has not been examined in patients with renal cell carcinoma (RCC). Our objective is to evaluate associations between low Cr/Cys-C ratio and OS and recurrence-free survival (RFS) in patients with RCC treated with nephrectomy. METHODS We performed a retrospective review of patients with RCC treated with nephrectomy. Patients with end-stage renal disease and less than 1-year follow up were excluded. Cr/Cys-C was dichotomized at the median for the cohort (low vs. high). OS and RFS for patients with high versus low Cr/Cys-C were estimated with the Kaplan-Meier method, and associations with the outcomes of interest were modeled using Cox proportional Hazards models. Associations between Cr/Cys-C and skeletal muscle mass were assessed with correlations and logistic regression. RESULTS A total of 255 patients were analyzed, with a median age of 64. Median (IQR) Cr/Cys-C was 1 (0.8-1.2). Low Cr/Cys-C was associated with age, female sex, Eastern Cooperative Oncology Group Performance Status ≥1, TNM stage, and tumor size. Kaplan-Meier and Cox regression analysis demonstrated an association between low Cr/Cys-C and decreased OS (HR = 2.97, 95%CI, 1.12-7.90, P =0.029) and RFS (HR = 3.31, 95%CI, 1.26-8.66, P = .015). Furthermore, a low Cr/Cys-C indicated a 2-3 increase in risk of radiographic sarcopenia. CONCLUSIONS Lower Cr/Cys-C is associated with inferior oncologic outcomes in RCC and, pending validation, may have utility as a serum biomarker for the presence of sarcopenia in patients with RCC treated with nephrectomy.

Immune-Related Adverse Events and Clinical Outcomes in Advanced Urothelial Cancer Patients Treated With Immune Checkpoint Inhibitors. Oncologist 2023; 28:1072-1078. [PMID: 37285524 PMCID: PMC10712712 DOI: 10.1093/oncolo/oyad154] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2022] [Accepted: 04/26/2023] [Indexed: 06/09/2023] Open
Abstract
BACKGROUND In advanced urothelial cancers (UC), immune checkpoint inhibitors (ICI) show promise as a durable therapy. Immune-related adverse events (irAEs), a side effect of ICIs, may serve as an indicator of beneficial response. We investigated the relationship between irAEs and clinical outcomes in patients with advanced UC who received ICI. MATERIALS AND METHODS In this retrospective study, we investigated 70 patients with advanced UC treated with ICIs at Winship Cancer Institute from 2015 to 2020. Data on patients were collected through chart review. Cox's proportional hazard model and logistic regression were applied to estimate the association with overall survival (OS), progression-free survival (PFS), and clinical benefit (CB). The possible lead-time bias was handled in extended Cox regression models. RESULTS The median age of the cohort was 68. Over one-third (35%) of patients experienced an irAE, with skin being the most frequent organ involved (12.9%). Patients that experienced at least one irAE had significantly enhanced OS (HR: 0.38, 95% CI, 0.18-0.79, P = .009), PFS (HR: 0.27, 95% CI, 0.14-0.53, P < .001), and CB (OR: 4.20, 95% CI, 1.35-13.06, P = .013). Patients who experienced dermatologic irAEs also had significantly greater OS, PFS, and CB. CONCLUSION Of patients with advanced UC that had undergone ICI therapy, those who had irAEs, especially dermatologic irAEs, had significantly greater OS, PFS, and CB. These results may suggest that irAE's may serve as an important marker of durable response to ICI therapy in urothelial cancer. The findings of this study need to be validated with larger cohort studies in the future.

Contemporary Patients Have Better Perioperative Outcomes Following Cytoreductive Nephrectomy: A Multi-institutional Analysis of 1272 Consecutive Patients. Urology 2023; 182:168-174. [PMID: 37690543 DOI: 10.1016/j.urology.2023.08.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2023] [Revised: 08/12/2023] [Accepted: 08/23/2023] [Indexed: 09/12/2023]
Abstract
OBJECTIVE To evaluate factors associated with perioperative outcomes in a multi-institutional cohort of patients treated with cytoreductive nephrectomy (CN). METHODS Data were analyzed for metastatic renal cell carcinoma patients treated with CN at 6 tertiary academic centers from 2005 to 2019. Outcomes included: Clavien-Dindo complications, mortality, length of hospitalization, 30-day readmission rate, and time to systemic therapy. Univariate and multivariable models evaluated associations between outcomes and prognostic variables including the year of surgery. RESULTS A total of 1272 consecutive patients were treated with CN. Patients treated in 2015-2019 vs 2005-2009 had better performance status (P<.001), higher pathologic N stage (P = .04), more frequent lymph node dissections (P<.001), and less frequent presurgical therapy (P = .02). Patients treated in 2015-2019 vs 2005-2009 had lower overall and major complications from surgery, 22% vs 39%, P<.001% and 10% vs 16%, P = .03. Mortality at 90days was higher for patients treated 2005-2009 vs 2015-2019; 10% vs 5%, P = .02. After multivariable analysis, surgical time period was an independent predictor of major complications and 90-day mortality following cytoreductive surgery. CONCLUSION Postoperative major complications and mortality rates following CN are significantly lower in patients treated within the most recent time period.

Abstract
A variety of primary malignant mesenchymal neoplasms can arise from the perinephric soft tissue and hilar vessels and potentially involve the kidney, mimicking primary renal tumors. A search was made at our institution for patients that underwent radical nephrectomy with associated perinephric or hilar sarcomas from 2010 to 2021. Twenty-six patients were identified. Mean patient age was 60 years (range: 34-83 years), with 16 (62%) females and 10 (38%) males. The mean tumor size was 21.6 cm (range: 8.1-36.5 cm). Among the perinephric/retroperitoneal sarcomas, 14/20 (70%) were dedifferentiated liposarcoma, 4/20 (20%) were well-differentiated liposarcoma, and 2/20 (10%) were leiomyosarcoma. There were 4 grade 1 (20%; all well-differentiated liposarcoma), 9 grade 2 (45%), and 7 grade 3 (35%) tumors. All 6 sarcomas arising from the renal vein/inferior vena cava were leiomyosarcoma: grade 2 in 1 (17%), grade 3 in 4 (67%), and ungraded (due to neoadjuvant therapy effect) in 1 (17%) patient. Four of the 26 (15%) tumors involved the ipsilateral kidney. All 4 tumors were grade 3 sarcomas. On follow-up, 8/26 (31%) patients developed local recurrence and/or metastasis. The mean time for recurrence was 22 months (range: 7-48 months). Two patients progressed with metastasis to the lungs, both of which were grade 3 leiomyosarcoma, and appeared 11 months after the initial diagnosis. Our data suggest that while local recurrence is prevalent with most subtypes of perinephric sarcomas, high-grade leiomyosarcoma has a distinct proclivity for distant metastasis, with the lungs being the most common site.

Abstract
Radical nephrectomy is the gold standard treatment for large renal cell carcinoma. Given the rising incidence of renal cell carcinoma and higher prevalence of geriatric patients in the population, readily identifying patients preoperatively that are at risk for a more complicated postoperative course is critical. The 5-factor modified frailty index (5-IFi) is a scoring system that assigns 1 point for each of the following comorbidities: dependent functional status, diabetes, chronic obstructive pulmonary disease, congestive heart failure, and hypertension. Patients with higher 5-IFi scores have been shown to be at significant risk for increased postoperative morbidity and mortality in many cohorts, including patients that undergo radical nephrectomy. This simplified comorbidity index with only 5 components is much more clinically pragmatic than its predecessors. As we encounter an increasing volume of patients with renal cell carcinoma and geriatric surgical candidates, readily risk stratifying patients on a personalized basis may be informative for shared clinical and surgical-decision making.

Abstract
ABSTRACT Preoperative differentiation of oncocytomas from renal cell carcinoma (RCC) is often challenging. 99mTc-MIBI imaging could play a potential role in differentiating oncocytoma from RCC, which in turn could guide surgical decision-making. We present the use of 99mTc-MIBI SPECT/CT to characterize a renal mass in a 66-year-old man with a complex medical history, including history of bilateral oncocytomas. 99mTc-MIBI SPECT/CT showed features suspicious of a malignant tumor, which was confirmed postnephrectomy as a chromophobe and papillary RCC collision tumor. This case supports 99mTc-MIBI imaging for preoperative differentiation of benign versus malignant renal tumors.

Abstract
PURPOSE Timely and effective physical activity (PA) prehabilitation is an evidence-based approach for improving a patient's health status preoperatively. Identifying barriers and facilitators to PA prehabilitation can help inform best practices for exercise prehabilitation program implementation. We explore the barriers and facilitators to PA prehabilitation in patients undergoing nephrectomy. METHODS A qualitative exploratory study was conducted by interviewing 20 patients scheduled for nephrectomy. Interviewees were selected via convenience sampling strategy. The interviews were semi-structured and discussed experienced and perceived barriers/facilitators to PA prehabilitation. Interview transcripts were imported to Nvivo 12 for coding and semantic content analysis. A codebook was independently created and collectively validated. Themes of barriers and facilitators were identified and summarized in descriptive findings based on frequency of themes. RESULTS Five relevant themes of barriers to PA prehabilitation emerged: 1) mental factors, 2) personal responsibilities, 3) physical capacity, 4) health conditions, and 5) lack of exercise facilities. Contrarily, facilitators potentially contributing to PA prehabilitation adherence in kidney cancer included 1) holistic health, 2) social and professional support, 3) acknowledgment of health benefits, 4) exercise type and guidance, and 5) Communication channels. CONCLUSION AND KEY FINDINGS Kidney cancer patient's adherence to physical activity prehabilitation is influenced by multiple biopsychosocial barriers and facilitators. Hence, adherence to physical activity prehabilitation requires timely adaptation of health beliefs and behavior embedded in the reported barriers and facilitators. For this reason, prehabilitation strategies should strive to be patient-centered and include health behavioral change theories as underlying frameworks for sustaining patient engagement and self-efficacy.

Abstract
BACKGROUND Renal cell carcinoma (RCC) with tumor thrombosis often requires nephrectomy and tumor thrombectomy. As an extensive and potentially morbid operation, patient preoperative functional reserve and body composition is an important consideration. Sarcopenia is a risk factor for increased postoperative complications, systemic therapy toxicity, and death solid organ tumors, including RCC. The influence of sarcopenia in RCC patients with tumor thrombus is not well defined. This study evaluates the prognostic ability of sarcopenia regarding surgical outcomes and complications in patients undergoing surgery for RCC with tumor thrombus. METHODS We retrospectively analyzed patients with nonmetastatic RCC and tumor thrombus undergoing radical nephrectomy and tumor thrombectomy. Skeletal muscle index (SMI; cm2/m2) was measured on preoperative CT/MRI. Sarcopenia was defined using body mass index- and sex-stratified thresholds optimally fit via a receiver-operating characteristic analysis for survival. Associations between preoperative sarcopenia and overall (OS), cancer-specific survival (CSS), and 90-day major complications were determined using multivariable analysis. RESULTS 115 patients were analyzed, with median (IQR) age and body mass index of 69 (56-72) and 28.6 kg/m2 (23.6-32.9), respectively. 96 (83.4%) of the cohort had ccRCC. Sarcopenia was associated with shorter median OS (P = .0017) and CSS (P = .0019) in Kaplan-Meier analysis. In multivariable analysis, preoperative sarcopenia was prognostic of shorter OS (HR = 3.38, 95% confidence interval [CI] 1.61-7.09) and CSS (HR = 5.15, 95% CI 1.46-18.18). Notably, 1 unit increases in SMI were associated with improved OS (HR = 0.97, 95% CI 0.94-0.999) but not CSS (HR = 0.95, 95% CI 0.90-1.01). No significant relationship between preoperative sarcopenia and 90-day major surgical complications was observed in this cohort (HR = 2.04, 95% CI 0.65-6.42). CONCLUSION Preoperative sarcopenia was associated with decreased OS and CSS in patients surgically managed for nonmetastatic RCC and VTT, however, was not predictive of 90-day major postoperative complications. Body composition analysis has prognostic utility for patients with nonmetastatic RCC and venous tumor thrombus undergoing surgery.

Abstract
PURPOSE OF REVIEW The purpose of this review is to provide an up-to-date understanding regarding the literature on sarcopenia and inflammation as prognostic factors in the context of renal cell carcinoma (RCC). RECENT FINDINGS Sarcopenia is increasingly recognized as a prognostic factor in RCC. Emerging literature suggests monitoring quantity of muscle on successive imaging and examining muscle density may be additionally informative. Inflammation has prognostic ability in RCC and is also considered a key contributor to development and progression of both RCC and sarcopenia. Recent studies suggest these two prognostic factors together may provide additional prognostic ability when used in combination. Ongoing developments include quality control regarding sarcopenia research and imaging, improving understanding of muscle loss mechanisms, and enhancing clinical incorporation of sarcopenia via improving imaging analysis practicality (i.e., artificial intelligence) and feasible biomarkers. Sarcopenia and systemic inflammation are complementary prognostic factors for adverse outcomes in patients with RCC. Further study on high-quality sarcopenia assessment standardization and expedited sarcopenia assessment is desired for eventual routine clinical incorporation of these prognostic factors.

Differences in Failure-Free Survival After Salvage Radiotherapy Guided by Conventional Imaging Versus 18F-Fluciclovine PET/CT in Postprostatectomy Patients: A Post Hoc Substratification Analysis of the EMPIRE-1 Trial. J Nucl Med 2023; 64:586-591. [PMID: 36328489 PMCID: PMC10071787 DOI: 10.2967/jnumed.122.264832] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 10/27/2022] [Accepted: 10/27/2022] [Indexed: 11/06/2022] Open
Abstract
The EMPIRE-1 (Emory Molecular Prostate Imaging for Radiotherapy Enhancement 1) trial reported a survival advantage in recurrent prostate cancer salvage radiotherapy (SRT) guided by 18F-fluciclovine PET/CT versus conventional imaging. We performed a post hoc analysis of the EMPIRE-1 cohort stratified by protocol-specified criteria, comparing failure-free survival (FFS) between study arms. Methods: EMPIRE-1 randomized patients to SRT planning via either conventional imaging only (bone scanning plus abdominopelvic CT or MRI) (arm A) or conventional imaging plus 18F-fluciclovine PET/CT (arm B). Randomization was stratified by prostate-specific antigen (PSA) level (<2.0 vs. ≥ 2.0 ng/mL), adverse pathology, and androgen-deprivation therapy (ADT) intent. We subdivided patients in each arm using the randomization stratification criteria and compared FFS between patient subgroups across study arms. Results: Eighty-one and 76 patients received per-protocol SRT in study arms A and B, respectively. The median follow-up was 3.5 y (95% CI, 3.0-4.0). FFS was 63.0% and 51.2% at 36 and 48 mo, respectively, in arm A and 75.5% at both 36 and 48 mo in arm B. Among patients with a PSA of less than 2 ng/mL (mean, 0.42 ± 0.42 ng/mL), significantly higher FFS was seen in arm B than arm A at 36 mo (83.2% [95% CI, 70.0-91.0] vs. 66.5% [95% CI, 51.6-77.8], P < 0.001) and 48 mo (83.2% [95% CI, 70.0-91.0] vs. 56.2% [95% CI, 40.5-69.2], P < 0.001). No significant difference in FFS between study arms in patients with a PSA of at least 2 ng/mL was observed. Among patients with adverse pathology, significantly higher FFS was seen in arm B than arm A at 48 mo (68.9% [95% CI, 52.1-80.8] vs. 42.8% [95% CI, 26.2-58.3], P < 0.001) though not at the 36-mo follow-up. FFS was higher in patients without adverse pathology in arm B versus arm A (90.2% [95% CI, 65.9-97.5] vs. 73.1% [95% CI, 42.9-89.0], P = 0.006) at both 36 and 48 mo. Patients in whom ADT was intended in arm B had higher FFS than those in arm A, with the difference reaching statistical significance at 48 mo (65.2% [95% CI, 40.3-81.7] vs. 29.1 [95% CI, 6.5-57.2], P < 0.001). Patients without ADT intent in arm B had significantly higher FFS than patients in arm A at 36 mo (80.7% [95% CI, 64.9-90.0] vs. 68.0% [95% CI, 51.1-80.2]) and 48 mo (80.7% [95% CI, 64.9-90.0] vs. 58.6% [95% CI, 41.0-72.6]). Conclusion: The survival advantage due to the addition of 18F-fluciclovine PET/CT to SRT planning is maintained regardless of the presence of adverse pathology or ADT intent. Including 18F-fluciclovine PET/CT to SRT leads to survival benefits in patients with a PSA of less than 2 ng/mL but not in patients with a PSA of 2 ng/mL or higher.

Impact of 18 F-Fluciclovine PET/CT Findings on Failure-Free Survival in Biochemical Recurrence of Prostate Cancer Following Salvage Radiation Therapy. Clin Nucl Med 2023; 48:e153-e159. [PMID: 36754362 PMCID: PMC9992149 DOI: 10.1097/rlu.0000000000004590] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 02/10/2023]
Abstract
PURPOSE We aimed to evaluate the impact of 18 F-fluciclovine PET/CT imaging on failure-free survival (FFS) post-salvage radiotherapy (SRT) for prostate cancer (PCa) recurrence. METHODS Seventy-nine patients were recruited in a phase 2/3 clinical trial to undergo 18 F-fluciclovine PET/CT before SRT for PCa. Four patients with extrapelvic disease were excluded. All patients were followed up at regular intervals up to 48 months. Treatment failure was defined as a serum prostate-specific antigen level of ≥0.2 ng/mL above the nadir after SRT, confirmed with an additional measurement, requiring systemic treatment or clinical progression. Failure-free survival was computed and compared between patients grouped according to 18 F-fluciclovine PET/CT imaging findings. RESULTS Eighty percent (60/75) of patients had a positive finding on 18 F-fluciclovine PET/CT, of which 56.7% (34/60) had prostate bed-only uptake, whereas 43.3% (26/60) had pelvic nodal ± bed uptake. Following SRT, disease failure was detected in 36% (27/75) of patients. There was a significant difference in FFS between patients who had a positive versus negative scan (62.3% vs 92.9% [ P < 0.001] at 36 months and 59.4% vs 92.9% [ P < 0.001] at 48 months). Similarly, there was a significant difference in FFS between patients with uptake in pelvic nodes ± bed versus prostate bed only at 36 months (49.8% vs 70.7%; P = 0.003) and at 48 months (49.8% vs 65.6%; P = 0.040). Failure-free survival was also significantly higher in patients with either negative PET/CT or prostate bed-only disease versus those with pelvic nodal ± prostate bed disease at 36 (78% vs 49.8%, P < 0.001) and 48 months (74.4% vs 49.8%, P < 0.001). CONCLUSIONS Findings on pre-SRT 18 F-fluciclovine PET/CT imaging, even when acted upon to optimize the treatment decisions and treatment planning, are predictive of post-SRT FFS in men who experience PCa recurrence after radical prostatectomy. A negative 18 F-fluciclovine PET/CT is most predictive of a lower risk of failure, whereas the presence of pelvic nodal recurrence portends a higher risk of SRT failure.

Cytoreductive Nephrectomy Following Immune Checkpoint Inhibitor Therapy Is Safe and Facilitates Treatment-free Intervals. EUR UROL SUPPL 2023; 50:43-46. [PMID: 36861106 PMCID: PMC9969293 DOI: 10.1016/j.euros.2023.01.016] [Citation(s) in RCA: 10] [Impact Index Per Article: 10.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 01/19/2023] [Indexed: 02/22/2023] Open
Abstract
Patients with metastatic renal cell cancer (mRCC) who respond to upfront immune checkpoint inhibitor (ICI) combination therapies may be treated with cytoreductive nephrectomy (CN) to remove radiographically viable primary tumors. Early data for post-ICI CN suggested that ICI therapies induce desmoplastic reactions in some patients, increasing the risk of surgical complications and perioperative mortality. We evaluated perioperative outcomes for 75 consecutive patients treated with post-ICI CN at four institutions from 2017 to 2022. Our cohort of 75 patients had minimal or no residual metastatic disease but radiographically enhancing primary tumors after ICI and were treated with CN. Intraoperative complications were identified in 3/75 patients (4%) and 90-d postoperative complications in 19/75 (25%), including two patients (3%) with high-grade (Clavien ≥III) complications. One patient was readmitted within 30 d. No patients died within 90 d after surgery. Viable tumor was present in all but one specimen. Approximately half of the patients (36/75, 48%) remained off systemic therapy at last follow-up. These data suggest that CN following ICI therapy is safe and associated with low rates of major postoperative complications in appropriately selected patients at experienced centers. Post-ICI CN may facilitate observation without additional systemic therapy in patients without significant residual metastatic disease. Patient summary Current first-line treatment for patients with kidney cancer that has spread to other sites (metastatic cancer) is immunotherapy. For cases in which metastatic sites respond to this therapy but primary tumor is still detected in the kidney, surgical treatment of the tumor is feasible and has a low rate of complications, and may delay the need for further chemotherapy.

Mayo Adhesive Probability Score Does Not Have Prognostic Ability in Locally Advanced Renal Cell Carcinoma. J Kidney Cancer VHL 2023; 10:19-25. [PMID: 36969300 PMCID: PMC10036918 DOI: 10.15586/jkcvhl.v10i1.269] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Accepted: 03/12/2023] [Indexed: 03/29/2023] Open
Abstract
Nephrectomy remains standard treatment for renal cell carcinoma (RCC). The Mayo Adhesive Probability (MAP) score is predictive of adherent perinephric fat and associated surgical complexity, and is determined by assessing perinephric fat and stranding. MAP has additionally predicted progression-free survival (PFS), though primarily reported in stage T1-T2 RCC. Here, we examine MAP's ability to predict overall survival (OS) and PFS in T3-T4 RCC. From our prospectively maintained RCC database, patients that underwent radical nephrectomy (2009-2016) with available abdominal imaging (<90 days preop) and T3/T4 RCC underwent MAP scoring. Survival analyses were conducted with MAP scores as individual (0-5) and dichotomized (0-3 vs 4-5) using Kaplan-Meier method. Multivariable Cox proportional hazard regression models for PFS and OS were built with backward elimination. 141 patients were included. 134 (95%) and 7 (5%) had pT3 and pT4 disease, respectively. 46.1% of patients had an inferior vena cava thrombus. Mean MAP score was 3.22±1.52, with 75 (53%) patients having a score between 0-3 and 66 (47%) having a score of 4-5. Both male gender (p=0.006) and clear cell histology (p=0.012) were associated with increased MAP scores. On Kaplan-Meier and multivariable analysis, no significant associations were identified between MAP and PFS (HR=1.01, 95% CI 0.85-1.20, p=0.93) or OS (HR=1.01, 95% CI 0.84-1.21, p=0.917). In this cohort of patients with locally advanced RCC, high MAP scores were not predictive of worse PFS or OS.

Baseline Neutrophil-to-Eosinophil Ratio Is Associated with Outcomes in Metastatic Renal Cell Carcinoma Treated with Immune Checkpoint Inhibitors. Oncologist 2023; 28:239-245. [PMID: 36427017 PMCID: PMC10020802 DOI: 10.1093/oncolo/oyac236] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 09/15/2022] [Indexed: 11/27/2022] Open
Abstract
BACKGROUND Biomarkers have the potential to guide treatment selection and clinical care in metastatic renal cell carcinoma (mRCC) in an expanding treatment landscape. We report baseline neutrophil-to-eosinophil ratios (NER) in patients with mRCC treated with immune checkpoint inhibitors (CPIs) and their association with clinical outcomes. METHODS We conducted a retrospective review of patients with mRCC treated with CPIs at Winship Cancer Institute from 2015 to 2020 in the United States of America (USA). Demographics, disease characteristics, and laboratory data, including complete blood counts (CBC) were described at the initiation of CPIs. Clinical outcomes were measured as overall survival (OS), progression-free survival (PFS), and clinical benefit (CB) associated with baseline lab values. RESULTS A total of 184 patients were included with a median follow-up time of 25.4 months. Patients with baseline NER were categorized into high or low subgroups; high group was defined as NER >49.2 and low group was defined as NER <49.2 with 25% of patients in the high NER group. Univariate analyses (UVA) and multivariable analyses (MVA) identified decreased overall survival (OS) associated with elevated NER. In MVA, patients with a high baseline NER group had a hazard ratio (HR) of 1.68 (95%CI, 1.01-2.82, P = .048) for OS; however, there was no significant difference between groups for PFS. Clinical benefit was seen in 47.3% of patients with low baseline NER and 40% with high NER. CONCLUSIONS We conclude that elevated baseline NER may be associated with worse clinical outcomes in mRCC. Although results require further validation, NER is a feasible biomarker in patients with CPI-treated mRCC.

Race-free renal function estimation equations and potential impact on Black patients: Implications for cancer clinical trial enrollment. Cancer 2023; 129:920-924. [PMID: 36606692 DOI: 10.1002/cncr.34637] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2022] [Revised: 11/17/2022] [Accepted: 11/28/2022] [Indexed: 01/07/2023]
Abstract
BACKGROUND Black patients face disparities in cancer outcomes. Additionally, Black patients are more likely to be undertreated and underrepresented in clinical trials. The recent recommendation to remove race from the estimated glomerular filtration rate (eGFR) results in lower eGFR values for Black patients. The ramifications of this decision, both intended and unintended, are still being elucidated in the medical community. Here, the authors analyze the removal of race from eGFR for Black patients with cancer, specifically with respect to clinical trial eligibility. METHODS In a cohort of self-identified Black patients who underwent nephrectomy at a tertiary referral center from 2009 to 2021 (n = 459), eGFR was calculated with and without race in commonly used equations (Chronic Kidney Disease Epidemiology Collaboration [CKD-EPI] and Modification of Diet in Renal Disease [MDRD]). The distribution of patients and changes within chronic kidney disease stages with different equations was considered. Theoretical exclusion at commonly observed clinical trial eGFR points was then simulated on the basis of the utilization of the race coefficient. RESULTS The median eGFR from CKD-EPI was significantly higher with race (76 ml/min/1.73 m2 ) than without race (66 ml/min/1.73 m2 ; p < .0001). The median eGFR from MDRD was significantly higher with race (71.0 ml/min/1.73 m2 ) than without race (58 ml/min/1.73 m2 ; p < .0001). Observing results in the context of common clinical trial cutoff points, the authors found that 13%-22%, 6%-12%, and 2%-3% more Black patients would fall under common clinical trial cutoffs of 60, 45, and 30 ml/min, respectively, depending on the equation used. A subanalysis of stage III-IV patients only was similar. CONCLUSIONS Race-free renal function equations may inadvertently result in increased exclusion of Black patients from clinical trials. This is especially concerning because of the underrepresentation and undertreatment that Black patients already experience. PLAIN LANGUAGE SUMMARY Black patients experience worse oncologic outcomes and are underrepresented in clinical trials. Kidney function, as estimated by glomerular filtration rate equations, is a factor in who can and cannot be in a clinical trial. Race is a variable in some of these equations. For Black patients, removing race from these equations leads to the calculation of lower kidney function. Lower estimated kidney function may result in more black patients being excluded from clinical trials. The inclusion of all races in clinical trials is important for offering best care to everyone and for making results from clinical trials applicable to everyone.

Abstract
617 Background: In renal cell carcinoma (RCC) and other solid organ malignancies, sarcopenia has been associated with decreased survival and increased perioperative complications. Traditional body composition analysis is an expensive and time extensive process. As a modifiable risk factor, more clinic friendly methods to identify patients with low muscle composition is of interest. Linear segmentation on routine imaging has been proposed as a fast, reliable and reproducible alternative. This study assesses the prognostic ability of linear segmentation in patients with nonmetastatic RCC. Methods: Patients that underwent nephrectomy for nonmetastatic RCC from 2005-2021 at an academic referral center were identified. Linear segmentation of the bilateral psoas/paraspinal muscles was completed on preoperative imaging obtained within 60 days of surgery. Cox proportional-hazards analysis was used to determine association between total muscle index and overall survival. Results: 532 (388 clear cell) patients were analyzed and a median total muscle index was 28.6 (25.8-32.5) for women and 33.3 (29.1-36.9) for men. As a binary variable, lower total muscle index was significantly associated with decreased survival in both the full (HR=1.96, 95% CI 1.32-2.90, p<0.001) and clear cell only cohorts (HR=1.78, 95% CI 1.08-2.75, p=0.022). As a continuous variable, unit increases in total muscle index were significantly associated with improved survival in the full cohort (HR=0.95, 95% CI 0.92-0.99, p=0.006) and the clear cell only cohort (HR=0.95, 95% CI 0.92-0.99, p=0.016). Conclusions: Assessment of muscle composition via linear segmentation on routinely obtained preoperative imaging is a clinically feasible technique with prognostic utility in patients with localized RCC. In this cohort of patients with nonmetastatic RCC, linear segmentation demonstrated significant associations with overall survival as a binary and continuous variable. This simplified technique may allow for routine inclusion of body composition into clinical decision making. [Table: see text]

Abstract
728 Background: Stage migration in renal cell carcinoma (RCC) has led to an increasing proportion of diagnoses at earlier clinical tumor stage and has rendered the phenomenon of the ‘small renal mass’ as a dominant presenting clinical paradigm. While thought of as being low risk, emerging knowledge about heterogeneity of RCC histologies and consequent impact on prognosis, in addition to awareness of impact of functional decline and demographic drivers on outcomes led us to further explore outcomes and predictive factors in T1a RCC patients treated with surgical resection. Methods: The INMARC database was queried for patients with small renal masses (≤ 4 cm) who underwent surgery via partial or radical nephrectomy and who presented without nodal or distant metastases. Patients were stratified into two groups based on having recurrence (distant or loco-regional) or not. Primary outcome was overall survival (OS). Multivariable analyses (MVA) were performed to analyze clinicopathological variables associated with recurrence and identify predictors of recurrence, cancer-specific mortality (CSM), and all-cause mortality (ACM). Kaplan-Meier analyses (KMA) were performed to compare recurrence-free survival (RFS), cancer-specific survival (CSS), and overall survival (OS) between histology types clear cell, chromophobe, papillary, and “other.” Results: We analyzed 1,878 cT1aN0M0 RCC patients; 101 (5.4%) developed recurrence (median follow up 53.6 months; median time to recurrence 19.3 months); 51.1% developed distant recurrence, 35.6% had loco-regional recurrence, and 13.9% experienced distant and loco-regional recurrence. MVA demonstrated age (HR=1.02, p=0.02), sex (HR=1.71, p=0.045), diabetes (HR=1.94, p=0.006), high/unclassified grade (HR=2.82-4.40, p<0.001-0.007), papillary (HR=0.37, p=0.013) and other (HR=2.51, p=0.019) RCC as predictive factors for recurrence. MVA identified high/unclassified grade (HR=3.17-6.22, p=0.002-0.003) and papillary RCC (HR=0.12, p=0.036) as predictive factors for CSM. MVA for ACM demonstrated age (HR=1.03, p<0.001), non-Caucasian race (HR=0.85, p<0.001), high grade (HR=1.42, p=0.024), recurrence (HR=1.86, p=0.003), and GFR<45 (HR=2.89, p<0.001) to be independent risk factors. KMA comparing Clear Cell, Papillary, Chromophobe and Other RCC revealed significant differences for 5-year CSS (97.8% vs. 99.3% vs. 98.5% vs. 87.0%, p=0.018) and 5-year RFS (92.4% vs. 96.0% vs. 97.8% vs. 81.7%, p<0.001), but not 5-year OS (89.4% vs. 85.2% vs. 93.2% vs. 73.7%, p=0.34). Conclusions: We noted differential outcomes in T1a RCC based on histology and grade for recurrence and CSM, while renal functional decline in addition to pathological factors and recurrence were predictive for ACM. These findings suggest consideration to refine management and post treatment surveillance strategies in T1a RCC.

Abstract
11 Background: Penile squamous cell carcinoma (pSCC) is a rare neoplasm with a poor prognosis and a need for biomarkers to guide treatment selection. We report an association of baseline inflammatory markers with outcomes in pSCC treated with immune checkpoint inhibitors (ICI). Methods: We performed a retrospective review of patients with pSCC from 2012-2022 at the Winship Cancer Institute at Emory University. Demographics, disease characteristics, and optimal cutoffs of biomarkers prior to ICI initiation were described. Neutrophil-to-lymphocyte (NLR), monocyte-to-lymphocyte (MLR), platelet-to-lymphocyte (PLR), and neutrophil-to-eosinophil ratios (NER) were obtained from complete blood count data. Clinical benefit with ICI was defined as complete response, partial response, or stable disease based on RECIST 1.1 criteria. Overall survival (OS) and progression-free survival (PFS) were assessed by the Kaplan-Meier method and univariate Cox regression (UVA) using SAS software with significance level set at p<0.05. Results: Twenty-one patients were included in which 71.4% were white and 28.6% were black. Median age at ICI initiation was 56 years (38-76). Most patients (65%) had an ECOG PS ≥2. Four patients (19.1%) had clinical benefit at best response to ICI. Most patients (76.2%) had disease progression and 14.3% were alive at last contact. Median OS was 8.4 months (mo) (95%CI: 2.3-15.7), and median PFS was 2.0 mo (95%CI: 1.3-3.2). Of 9 patients with available HPV status, 8 were HPV+. Of 12 patients with available PD-L1 status, 8 were PD-L1+. Median follow-up was 8.4 mo and median time to ICI treatment from diagnosis was 15.6 mo. High baseline NLR, MLR, PLR, and NER above optimal cut were significantly associated with shorter OS on UVA (Table,all p<0.05). High baseline NLR was associated with shorter PFS (p=0.003). Baseline NLR groups were similar except for age and without differences in race, ECOG, BMI, PD-L1, and HPV status. Conclusions: Our real-world analysis reports a potential association of baseline inflammatory biomarkers with clinical outcomes in ICI-treated pSCC. More prospective and multicenter studies are needed for further confirmation. [Table: see text]

Abstract
503 Background: Pts presenting with NMIBC carcinoma in situ (CIS) have a high risk of progression. FGFR inhibition may benefit CIS pts with FGFRalt who are unresponsive to first-line BCG, for whom treatment (tx) options, other than radical cystectomy, are limited. Erdafitinib (erda), an oral selective pan-FGFR tyrosine kinase inhibitor, is approved for locally advanced or metastatic urothelial cancer in adults with FGFR3/2alt who have progressed during or after ≥1 line of platinum-containing chemotherapy. THOR-2 (NCT04172675) is a multicohort phase 2 study of erda in pts with HR-NMIBC. Here we report results from an exploratory cohort of pts with BCG-unresponsive CIS with FGFRalt with or without papillary disease (Cohort 2). Methods: Inclusion criteria: age ≥18 y, with histologically confirmed, BCG-unresponsive HR-NMIBC with FGFR3/2alt (by local/central testing) presenting as CIS, with or without a papillary tumor and who refused or were not eligible for cystectomy. In this cohort, pts received continuous oral erda 6 mg once daily without uptitration in 28-d cycles (dose selected to improve tolerability while maintaining activity to prevent disease recurrence, for this population). Erda was discontinued if no complete response (CR) was observed within 3 mos. Exploratory efficacy end points are CR rates at the Cycle 3 Day 1 (C3D1) disease evaluation and the Cycle 6 Day 1 (C6D1) disease evaluation; safety was a key secondary end point. Results: As of the data cutoff (Sep 2022) (median follow-up of 10 mos), 10 pts have received erda (enrolled population; median age 72 y [range 52-83]; 90% CIS [1 pt with Ta was mis-enrolled]). Pts received erda for a median duration 5.9 mos (range 1.1-17.0). Of 10 enrolled pts, the CR rates at first evaluation (C3D1) and second evaluation (C6D1) were 100% (9/9 evaluable pts) and 75% (6/8 evaluable pts), respectively. The median duration of response was 3.0 mos. The most common tx-emergent adverse events (TEAEs) were dry mouth (60%; n=6), hyperphosphatemia (50%; n=5), dysgeusia (50%; n=5), and diarrhea (50.0%; n=5). 1 pt (10%) had Gr 2 retinal detachment which led to tx discontinuation and 1 pt (10%) had Gr 1 subretinal fluid; both reported as resolved. Gr ≥3 tx-related TEAEs occurred in 3 pts (30%), and included dry mouth, stomatitis, nail disorder, onychomadesis, acute kidney injury, chronic kidney disease, sepsis, and hypotension in 1 pt each. 1 pt (10%) had serious tx-related TEAEs (dry mouth, hypotension, pneumonitis, acute kidney injury, and sepsis), and 1 pt (10%) discontinued tx due to a tx-related TEAE. No tx-related deaths were observed. Conclusions: Data from Cohort 2 of THOR-2 demonstrate efficacy at C3D1 and C6D1 evaluations in pts with HR-NMIBC with FGFRalt. Safety data were consistent with the known safety profile of erda. Clinical trial information: NCT04172675 .

Is pathological upstaging to T3a renal cell carcinoma associated with a similar prognosis to non-upstaged pathologic T3a disease? A multicenter analysis. J Clin Oncol 2023.

Abstract
656 Background: Pathological upstaging to T3a disease may occur following radical (RN) or partial nephrectomy (PN) for patients with T1/T2 renal cell carcinoma (RCC). While a number of studies have demonstrated increased risk of T1/T2 upstaging to pT3a compared to initial staging, a comparison of pathologically upstaged T3a RCC and T3a RCC which was not upstaged has not been performed. We sought to compare survival outcomes and predictors of outcomes in patients who underwent surgical therapy for upstaged T3a RCC versus non-upstaged pT3a RCC. Methods: We conducted a retrospective analysis of a multi-institutional dataset of patients who underwent radical (RN) or partial nephrectomy (PN) with final pathologic stage of pT3a. Patients were classified as being upstaged (US) from cT1 or cT2 or non-upstaged (NUS) with cT3a disease. Primary outcome was Overall Survival (OS)/all-cause mortality (ACM). Secondary outcomes were Cancer-Specific Survival (CSS)/Cancer-Specific Mortality (CSM), and Recurrence-Free survival (PFS)/Recurrence. Multivariable Cox regression analysis (MVA) were conducted for predictors of mortality outcomes and Kaplan Meier Analyses (KMA) were conducted to elucidate survival outcomes comparing US and NUS groups. Results: We analyzed 879 patients [US 691 (cT1 389/cT2 302); NUS 188; median follow-up 48 months). NUS had significantly greater tumor size (9.3 vs. US 7.3 cm, p<0.001), but no difference in positive surgical margins (6.9% vs. 3.9%, p=0.16). MVA for ACM revealed RN (HR 4.35, p<0.001), clear-cell RCC (HR 2.38, p<0.001), and positive surgical margin (HR 2.24, p=0.023) were independently associated, while upstaging status was not (p=0.78). MVA for CSM demonstrated age (HR 1.04, p=0.024) and positive margin (HR 5.28, p=0.029) were independently associated, while upstaging status was not (p=0.14). MVA for recurrence revealed positive margin (HR 6.7, p=0.003) and NUS (HR 3.85, p=0.001) to be associated with increased risk. KMA Comparing NUS and US groups, revealed no difference in 5-year OS (57% NUS vs. US 56%, p=0.38), and worsened 5-year CSS (NUS 66% vs. US 75%, p=0.04) and 5-year RFS (NUS 60% vs. US 84%, p<0.001). Conclusions: Pathologic upstaging to T3a RCC was associated with a lower risk of recurrence compared to non-pathologically upstaged T3a RCC; nonetheless in our analysis upstaging status was not independently associated with increased risk of cancer-specific or overall mortality in T3a RCC. Our findings also highlight the importance of complete surgical resection in the setting of T3a disease and should prompt consideration of intensified follow up, aggressive re-salvage resection and use of adjuvant therapy.

Abstract
616 Background: Accurate prediction of future glomerular function rate (fGFR) following nephrectomy in renal cell carcinoma (RCC) patients is of interest. A postoperative estimated glomerular filtration (eGFR) rate ≥ 45 mL/min/1.73m2 is considered favorable, with guidelines reflecting these findings. Though nephron sparing surgery is preferable, radical nephrectomy is often the preferred oncologic surgery. Various models to predict postoperative renal function have been proposed, with a new 2021 equation by Palacios et al. exhibiting strong performance in predicting fGFR. We aim to validate this fGFR equation in a large institutional cohort using both the Chronic Kidney Disease Epidemiology (CKD-EPI) 2009 equation with race, used in the creation of the formula, as well as the CKD-EPI 2021 equation without race, which is currently the recommended CKD-EPI creatinine equation. Methods: Using an institutional database, patients that underwent partial or radical nephrectomy for RCC from 2005-2021 were identified. Patients with creatinine values preoperatively and 3-12 months postoperatively were included, with end stage renal disease serving as exclusion criteria. Correlation/bias/accuracy/precision of the fGFR equation (fGFR=35+ [preoperative eGFR x 0.65]- 18 [if radical] - [age x 0.25]+ 3 [if tumor >7cm]-2 [if diabetes]) with observed postoperative eGFR was determined by both the CKD-EPI-2021 and CKD-EPI 2009 equations. Results: 1,443 patients were included in our analysis. 71% (1,024) and 22.9% (331) patients were white and black, respectively. A majority of patients underwent radical nephrectomy (60.3%). 40% of patients had T3-T4 RCC, with 14.8% of patients having M1 disease. Median observed vs predicted fGFR was 58.0 vs 58.7 ml/min/1.73m2 for CKD-EPI 2021 and 56.0 vs 57.5 for CKD-EPI 2009. The correlation/bias/accuracy/precision of the fGFR equation was 0.805/-0.5/81.7/7.9-9.0 for CKD-EPI 2021 and 0.809/-0.8/81.3/-8.1-8 for CKD-EPI 2009 equations (Table). Conclusions: The fGFR equation accurately predicted renal function in our large and diverse institutional cohort using both the CKD-EPI 2009 including race and CKD-EPI 2021 excluding race equations.

Abstract
697 Background: Creatinine and cystatin C are routinely used to assess renal function. Given creatinine originates from skeletal muscle and cystatin C is produced by nucleated cells, a creatinine to cystatin C ratio (Cr/Cys-C) may positively correlate with muscle mass. Low Cr/Cys-C has also been associated with decreased overall survival (OS) in cancer, including in a combined cohort of genitourinary malignancies. Furthermore, elevated cystatin c has been associated with shorter OS and recurrence free survival (RFS) in renal cell carcinoma (RCC). Cr/Cys-C may be a simple and affordable tool to assist with patient-specific risk stratification. We assess the ability of Cr/Cys-C to predict OS and RFS in patients with RCC. Methods: Retrospective review of a prospectively maintained database identified patients that underwent partial or radical nephrectomy for RCC from 2018-2021. Included patients had preoperative creatinine and cystatin C and 1+ year of follow up. Cr/Cys-C associations with patient/tumor characteristics were determined by generalized chi-square or Fisher’s exact tests for categorical variables and Wilcoxon rank-sum test for continuous variables. Cr/Cys-C ability to predict OS and RFS was analyzed with Kaplan-Meier method and Cox hazards models. Statistical tests were two-sided with type I error set at 0.05. Results: 219 patients were identified. Median age was 64, with most being male (67%). 62% and 29% of patients were white and black, respectively. Median eGFR was 72mL/min/1.73m2. Median (IQR) Cr/Cys-C was 1 (0.8-1.2). 55% were stage T3-T4, with 12% N1 and 16% M1 at time of surgery. 72% had clear cell histology. Low Cr/Cys-C was significantly associated with older age, males, Eastern Cooperative Oncology Group score ≥ 1, radical nephrectomy, T3-T4 stage, and metastasis. Kaplan-Meier curves showed low Cr/Cys-C association with decreased OS (p=0.0003) and RFS (p=0.0094). Cox regression analysis revealed lower Cr/Cys-C as independent predictor of decreased OS (binary HR=3.66, 95% CI 1.2-11.3, p=0.02; continuous HR=0.05, 95% 0.0-0.8, p=0.03) and RFS (binary HR=4.8, 95% CI 1.6-14.6, p=0.006; continuous HR=0.02, 95% 0.0-0.3, p=0.006;Table). Conclusions: Lower Cr/Cys-C may be associated with decreased OS and RFS in patients with RCC. [Table: see text]

Effect of race-free estimated glomerular filtration rate equations (eGFR) on oncology clinical trial eligibility for Black patients. J Clin Oncol 2023.

Abstract
611 Background: Race is no longer recommended in estimated glomerular filtration rate (eGFR) equations. The resulting lower eGFR may positively impact black patients, such as with earlier nephrology referral. However, the impact of race-free equations on black oncology patients–a cohort more likely to experience inferior cancer outcomes and underrepresentation in clinical trials–has not been fully examined. Here, we analyze removal of race from eGFR in black patients with cancer, specifically with regards to clinical trial eligibility. Methods: Self-identified black patients undergoing nephrectomy at a referral center from 2009-2021 were identified. Patients with end-stage renal disease were excluded. Using preoperative creatinine, height, and weight, eGFR was calculated with the Chronic Kidney Disease Epidemiology Collaboration creatinine equation with and without race (CKD-EPI-WithRace; CKD-EPI-WithoutRace, respectively), and the Modification of Diet in Renal Disease equation with and without race (MDRD-WithRace; MDRD-WithoutRace, respectively). Distribution of patients and changes within CKD stages with different equations was considered. Theoretical exclusion at commonly observed clinical trial eGFR points was then simulated based on utilization of the race coefficient. Subgroup analysis was completed on patients with stage III-IV disease only. Results: 459 self-identified black patients that underwent nephrectomy at our institution were identified, 135 of which had stage III-IV disease. On average, eGFR decreased around 10-13ml/min/1.73m2 with removal of the race coefficient (Table). 13-22%, 6-12%, and 2-3% more black patients would fall under common clinical trial cutoffs of 60, 45, or 30ml/min cutoffs, respectively, depending on the equation used (Table). Subanalysis of stage III-IV patients only were similar. Conclusions: Race free renal function equations may inadvertently result in increased exclusion of black patients from clinical trials.

Abstract
732 Background: Patients with pathologically upstaged tumors have worse survival outcomes than their non-upstaged matched counterparts. However, we do know that original clinical tumor staging does still predict outcomes. We sought to examine if pathologic upstaging incrementally may more rationally stratify cancer specific survival outcomes. Methods: Multi-institutional (Emory, TMDU, UCSD) retrospective analysis of patients with renal cell carcinoma who underwent partial or radical nephrectomy between 1998-2020. Patients were divided into cT1 upstaged to pT3 (cT1/pT3), cT2 non-upstaged (cT2/pT2), cT2 upstaged to pT3 (cT2/pT3), and cT3 non-upstaged (cT3/pT3). Patients were analyzed for demographics, clinical parameters, and post-surgical outcomes. Primary outcome was cancer specific mortality (CSM). Secondary outcomes were all cause mortality and recurrence free survival. Cox regression was utilized to analyze factors associated with outcomes. Kaplan Meier analysis (KMA) was performed to analyze 5-year cancer specific survival. ROC analysis was utilized to compare predictive value of AJCC 8th edition TNM staging vs proposed staging. Results: 1093 patients were analyzed (283 cT1/pT3, 237 cT2/pT2, 244 cT2/pT3, and 329 cT3/pT3). Median follow-up was 25.9 months. Cox regression demonstrated that cT2/pT3 (HR 2.7, p<0.001 vs. cT1/pT3 [referent]) and cT3/pT3 (HR 2.6, p<0.001 vs. cT1/pT3 [referent]) were significantly associated with worsened cancer specific mortality, while cT1/pT3 (HR 0.4, p<0.001 vs. cT3/pT3 [referent]) and cT2/pT2 (HR 0.4, p<0.001 vs. cT3/pT3 [referent]) were associated with improved cancer specific mortality. Based on this, we proposed to realign cT1/pT3 with cT2/pT2 and cT2/pT3 with cT3/pT3. KMA revealed significant differences in 5-year cancer specific survival (cT1/pT3 82%, cT2/pT2 81%, cT2/pT3 67%, and cT3/pT3 60%, p<0.001). There were significant differences in 5-year overall survival (cT1/pT3 63%, cT2/pT2 67%, cT2/pT3 49%, and cT3/pT3 49%, p<0.001), and 5-year recurrence free survival (cT1/pT3 80%, cT2/pT2 83%, cT2/pT3 70%, and cT3/pT3 59%, p<0.001) on KMA. ROC analysis revealed an AUC of 0.529 for CSM and AUC of 0.502 for ACM using the current AJCC 8th edition TNM staging. ROC analysis revealed an AUC of 0.597 for CSM and AUC of 0.545 for our new proposal. Conclusions: Our analysis suggests that cT1 tumors pathologically upstaged to pT3 behave more similarly to pT2 tumors. Further delineation of pathologically upstaged tumors may more rationally stratify cancer specific survival outcomes to guide patient counseling and clinical decision making.

Abstract
9 Background: The efficacy of neoadjuvant platinum-based chemotherapy (NAPC) in penile squamous cell carcinoma (PSCC) was provided by small clinical trials, leaving clinicians with scant evidence-based guidance. Thus, we aimed to analyze real-world outcomes of patients with PSCC who received NAPC prior to surgical resection. Methods: Patients from 9 tertiary care centers who had undergone NAPC prior surgical resection for PSCC were included with locally advanced (cTany, cN+), non-metastatic (M0) disease. The primary and secondary outcomes were overall survival (OS) and progression-free survival (PFS), Response was determined via best overall response measured with RECIST 1.1 criteria. Results: 167 patients were included, 137 (84%), of which received TIP prior to surgical resection. Ninety-two (55%) patients died during follow up, and the mean follow up for survivors was 57 months. The median OS was 42 months, while the median PFS was 17 months. The table details the response rates to NAPC, the associated survival, and Cox Proportional Hazards Modelling of OS and PFS. Predictors for OS and RFS included lymphovascular invasion, positive number of lymph nodes, extranodal extension, downstaging, best overall response, and ypN status. Figure 1 demonstrates OS outcomes by RECIST best response after chemotherapy, presence of downstaging after NAPC, ypN stage, and presence of extranodal extension. Conclusions: Upfront NAPC is effective in patients with lymph node metastases from penile carcinoma. Unsurprisingly, patients who demonstrated a robust response to therapy had improved survival outcomes compared to those who had not—as measured by RECIST criteria, tumor downstaging, pN staging, and presence of extranodal extension. This study represents the largest conglomeration of multi-institutional penile carcinoma patients treated with NAPC, and provides further supportive data for multimodal therapy for advanced penile cancer patients while prospective clinical trials complete accrual.

Abstract
658 Background: Patients with cancer experience depression at higher rates, which is associated with worse outcomes and quality of life. In renal cell carcinoma (RCC) specifically, depression is particularly prevalent. Aside from the emotional distress of a cancer diagnosis, a biologic basis for cancer associated depression is inflammation, which is highly associated with RCC as well as worse outcomes. Here, we aim to assess the association between inflammation and major depression, measured by a score of 10+ on the Patient Health Questionnaire (PHQ-8), in patients undergoing nephrectomy for nonmetastatic RCC. Methods: A retrospective review of prospectively administered PHQ-8 surveys in patients that underwent nephrectomy for nonmetastatic RCC was conducted. Patients with available preoperative PHQ-8 within 180 days before surgery were included. Association of major depression on PHQ-8 with patient/tumor characteristics were determined by Generalized chi-square test or Fisher’s exact test for categorical variables and Wilcoxon rank-sum test for continuous variables. Multivariable logistic regression was used to determine variables significantly associated with major depression on PHQ-8, including pre-operative C-Reactive Protein (CRP) independently and combined with American Joint Committee on Cancer (AJCC) staging for RCC. Results: 224 patients were analyzed, with 67% being male. Median age and BMI was 64 and 29.0, respectively. 65.2% of patients were white, and 28.6% were black. Histologically, most patients had clear cell RCC (67.4%). AJCC staging was 52.2% stage I, 5.36% stage II, and 42.41% stage III. 30.4% had an elevated CRP (>10mg/L). Median PHQ-8 score was 4, with 42 (18.8%) of patients screening positive for major depression on PHQ-8 (10+). Multivariable regression models showed elevated CRP alone (OR 2.74, 95% CI 1.02-7.40, p=0.047) and in-combination with AJCC stage I-II (OR=8.13, 95% CI 1.99-33.27, p=0.004) and III (OR=4.82, CI 1.11-20.88, p=0.035) as a predictor of major depression on PHQ-8. Conclusions: In this study of patients with nonmetastatic RCC, elevated CRP (>10mg/L) was an independent predictor of major depression on PHQ-8. [Table: see text]

Abstract
LBA602 Background: The increasing detection of renal masses presents a significant patient management challenge. Diagnostic options include cross-sectional imaging, which cannot reliably differentiate benign and malignant renal masses, and biopsy, which is invasive and subject to sampling errors. These limitations highlight the unmet need for accurate noninvasive techniques to guide patient management. Girentuximab is a monoclonal antibody that targets carbonic anhydrase IX (CAIX), an enzyme highly expressed in clear cell renal carcinoma (ccRCC). Radiolabeled 89Zr-DFO-girentuximab (TLX250-CDx) is highly specific for CAIX and can aid differentiation between ccRCCs and other renal lesions. The ZIRCON study evaluated the performance of TLX250-CDx PET/CT for detection of ccRCC in adult patients with indeterminate renal masses (IDRM). Methods: ZIRCON was an open-label, multicenter clinical trial. Patients with an IDRM (≤ 7 cm; tumor stage cT1) who were scheduled for partial nephrectomy within 90 days from planned TLX250-CDx administration were eligible. Enrolled patients received a single dose of TLX250-CDx IV (37 MBq ± 10%; 10 mg girentuximab) on Day 0 and underwent PET/CT imaging on Day 5 (± 2 days) prior to surgery. Blinded central histology review determined ccRCC status. The coprimary objectives were to evaluate both the sensitivity and specificity of TLX250-CDx PET/CT imaging in detecting ccRCC in patients with IDRM, using histology as the standard of truth. Key secondary objectives included sensitivity and specificity of TLX250-CDx PET/CT imaging in the subgroup of patients with IDRM ≤ 4 cm (cT1a). Other secondary objectives included positive and negative predictive values, safety, and tolerability. The Wilson 95% confidence intervals (CI) lower bound for sensitivity and specificity had to be > 70% and 68% respectively for ≥ 2 independent readers to declare the study successful. Results: 300 patients received TLX250-CDx; mean age was 62 ± 12 y; 71% were males. Of 288 patients with central histopathology of surgical samples, 193 (67%) had ccRCC, and 179 (62%) had CT1a; Of 284 evaluable patients included in primary analysis, the average across all 3 readers for sensitivity and specificity was 86% [80%, 90%] and 87% [79%, 92%] respectively for coprimary endpoints; and 85% [77%, 91%] and 90% [79%, 95%] respectively for key secondary endpoints. For all readers, the lower boundaries of 95% CI for coprimary and key secondary endpoints were > 75%. For all evaluable patients, positive and negative predictive values were ≥ 91.7% and ≥ 73.7%, respectively. Of 263 treatment-emergent adverse events (TEAEs), 2 TEAEs were treatment related. Conclusions: This study confirms that TLX250-CDx PET/CT is well tolerated and can accurately and noninvasively identify ccRCC, with promising utility for designing best management approaches for patients with IDRM. Clinical trial information: NCT03849118 .

Abstract
INTRODUCTION A universally accepted model for preoperative surgical risk stratification in localized RCC patients undergoing nephrectomy is currently lacking. Both the evaluation of body composition and nutritional status has demonstrated prognostic value for patients with cancer. This study aims to investigate the potential associations between sarcopenia and hypoalbuminemia and survival outcomes in patients with localized kidney cancer treated with partial or radical nephrectomy. MATERIALS AND METHODS We retrospectively analyzed 473 patients with localized RCC managed with radical and partial nephrectomy. Skeletal muscle index (SMI) was measured from preoperative CT and MRI. Sarcopenic criteria were created using BMI- and sex-stratified thresholds. Relationships between sarcopenia and hypoalbuminemia (Albumin <3.5 g/dL) with overall (OS), recurrence-free (RFS), and cancer-specific survival (CSS) were determined using multivariable and Kaplan-Meier analysis. RESULTS Of the 473 patients, 42.5% were sarcopenic and 24.5% had hypoalbuminemia. Sarcopenia was significantly associated with shorter OS (HR=1.51, 95% CI 1.07-2.13), however, was nonsignificant in the RFS (HR = 1.33, 95% CI 0.88-2.03) and CSS (HR=1.66, 95% CI 0.96-2.87) models. Hypoalbuminemia predicted shorter OS (HR=1.76, 95% CI 1.22-2.55), RFS (HR=1.86, 95% CI 1.19-2.89), and CSS (HR=1.82, 95% CI 1.03-3.22). Patients were then stratified into low, medium, and high-risk groups based on the severity of sarcopenia and hypoalbuminemia. Risk groups demonstrated an increasing association with shorter OS (all p<0.05). Reduced RFS was observed in the medium risk-hypoalbuminemia (HR=2.18, 95% CI 1.16-4.09) and high-risk groups (HR=2.42, 95% CI 1.34-4.39). Shorter CSS was observed in the medium risk-hypoalbuminemia (HR=2.31, 95% CI 1.00-5.30) and high-risk groups (HR=2.98, 95% CI 1.34-6.61). CONCLUSION Localized RCC patients with combined preoperative sarcopenia and hypoalbuminemia displayed a two to a three-fold reduction in OS, RFS, and CSS after nephrectomy. These data have implications for guiding prognostication and treatment election in localized RCC patients undergoing extirpative surgery.

Abstract
The role of cytoreductive nephrectomy in patients with metastatic renal cell carcinoma is a subject of debate. We report a durable complete response in a 62-year-old man Jehovah’s Witness with metastatic clear cell renal cell carcinoma who received two cycles of nivolumab/ipilimumab followed by radical nephrectomy and metastasectomy of known pulmonary disease site, both without a clinical need for perioperative blood transfusions. The patient continues to be without evidence of disease and without additional need for systemic therapy over a year after his radical nephrectomy. The case highlights that cytoreductive nephrectomy continues to play a role in the era of immune checkpoint inhibitors.

Abstract
PURPOSE The aim of this joint guideline is to provide evidence-based recommendations to practicing physicians and other health care providers on integrative approaches to managing pain in patients with cancer. METHODS The Society for Integrative Oncology and ASCO convened an expert panel of integrative oncology, medical oncology, radiation oncology, surgical oncology, palliative oncology, social sciences, mind-body medicine, nursing, and patient advocacy representatives. The literature search included systematic reviews, meta-analyses, and randomized controlled trials published from 1990 through 2021. Outcomes of interest included pain intensity, symptom relief, and adverse events. Expert panel members used this evidence and informal consensus to develop evidence-based guideline recommendations. RESULTS The literature search identified 227 relevant studies to inform the evidence base for this guideline. RECOMMENDATIONS Among adult patients, acupuncture should be recommended for aromatase inhibitor-related joint pain. Acupuncture or reflexology or acupressure may be recommended for general cancer pain or musculoskeletal pain. Hypnosis may be recommended to patients who experience procedural pain. Massage may be recommended to patients experiencing pain during palliative or hospice care. These recommendations are based on an intermediate level of evidence, benefit outweighing risk, and with moderate strength of recommendation. The quality of evidence for other mind-body interventions or natural products for pain is either low or inconclusive. There is insufficient or inconclusive evidence to make recommendations for pediatric patients. More research is needed to better characterize the role of integrative medicine interventions in the care of patients with cancer.Additional information is available at https://integrativeonc.org/practice-guidelines/guidelines and www.asco.org/survivorship-guidelines.
