Renal Cell Carcinoma with Venous Tumor Thrombus Has a Predilection for the Lungs.

Objectives: To investigate the association between venous tumor thrombus (VTT) and the risk of pulmonary metastases in patients with clear cell renal cell carcinoma (ccRCC).

Methods: We queried our institutional registry for ccRCC patients undergoing radical nephrectomy (1970-2019). Cox proportional hazards regression models, adjusting for factors associated with ccRCC progression, were used to determine whether VTT was associated with pulmonary metastases.

Role of B7-H3 in predicting response to neoadjuvant chemotherapy in muscle-invasive bladder cancer.

Background: Neoadjuvant platinum-based chemotherapy offers a modest survival advantage in muscle-invasive bladder cancer (MIBC) for patients with pathologic response. B7-H3 (), an immune checkpoint overexpressed in various cancers, including urothelial-cell carcinoma (UCC), has been associated with chemoresistance and poor oncologic outcomes. We aimed to explore if B7H3 expression on bladder biopsy samples was a predictive biomarker for pathologic response to neoadjuvant platinum-based chemotherapy.

Differences in preoperative frailty assessment of surgical candidates by sex, age, and race.

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.

2018 Leibovich prognostic model for renal cell carcinoma: Performance in a large population with special consideration of Black race.

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.

Relative impact of lymph-node metastasis and seminal vesical invasion on oncologic outcomes following radical prostatectomy.

Background: While both seminal vesicle (SVI) and lymph-node invasion (LNI) have been identified as adverse prognostic variables among men undergoing radical prostatectomy (RP), the relative impact of each of these features on subsequent oncologic outcomes has not been well defined. We assessed the impact of LNI on long-term oncologic outcomes among patients with SVI at RP.

Methods: We reviewed 19,519 patients who underwent RP and identified 2043 with SVI.

Cutaneous Ureterostomy Following Radical Cystectomy for Bladder Cancer: A Contemporary Series.

Objective: To report peri-operative outcomes of a contemporary series of bladder cancer patients undergoing radical cystectomy (RC) with cutaneous ureterostomy (CU) urinary diversion at a tertiary referral center.

Methods: We retrospectively identified patients who underwent RC with CU at Mayo Clinic between 2016 and 2021. Clinicopathologic and perioperative characteristics were analyzed using standard descriptive statistics.

Creatinine to Cystatin-C Ratio in Renal Cell Carcinoma: A Clinically Pragmatic Prognostic Factor and Sarcopenia Biomarker.

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.

Circulating antigen-primed cytotoxic T-cells in patients with renal tumors treated with surgery.

Introduction: Systemic immunotherapy has changed the paradigm of treatment of advanced renal cell carcinoma, but nephrectomy continues to benefit selected patients. While we continue to identify mechanisms behind drug resistance, the effect of surgery on natural anti-tumor immunity is poorly understood. Specifically, peripheral blood mononuclear cell (PBMC) profile and tumor reactive cytotoxic T lymphocytes changes secondary to tumor resection have not been extensively characterized.

The Impact of Metastasis Histopathology on Oncologic Outcomes for Patients With Surgically Resected Metastatic Renal Cell Carcinoma.

Purpose: Multiple prognostic models exist to assess survival among patients with metastatic clear cell renal cell carcinoma. However, the relative contribution of histopathological features of the metastasis has not been extensively studied. Herein, we compared models using clinical, primary tumor, and metastatic features to predict cancer-specific survival for patients with surgically resected metastatic clear cell renal cell carcinoma.

Low Skeletal Muscle as a Risk Factor for Worse Survival in Nonmetastatic Renal Cell Carcinoma with Venous Tumor Thrombus.

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.

A Novel PD-L1 Antibody Promotes Antitumor Function of Peripheral Cytotoxic Lymphocytes after Radical Nephrectomy in Patients with Renal Cell Carcinoma.

The intrinsic and acquired resistance to PD-1/PD-L1 immune checkpoint blockade is an important challenge for patients and clinicians because no reliable tool has been developed to predict individualized response to immunotherapy. In this study, we demonstrate the translational relevance of an ex vivo functional assay that measures the tumor cell killing ability of patient-derived CD8 T and NK cells (referred to as "cytotoxic lymphocytes," or CLs) isolated from the peripheral blood of patients with renal cell carcinoma. Patient-derived PBMCs were isolated before and after nephrectomy from patients with renal cell carcinoma.

Mayo Adhesive Probability Score Does Not Have Prognostic Ability in Locally Advanced Renal Cell Carcinoma.

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.

Antibody-Based Therapeutics for the Treatment of Renal Cell Carcinoma: Challenges and Opportunities.

Renal cell carcinoma (RCC) is among the top 10 most common cancers in both men and women with an estimated 75 000 cases each year in the US. Over the last decade, the therapeutic landscape for patients with metastatic RCC has significantly evolved, with immunotherapy emerging as the new front-line therapy. Despite significant improvement in toxicity profile and survival outcomes, key concerns such as patient selection, treatment sequencing, and intrinsic and acquired resistance remain unresolved.

Race-free renal function estimation equations and potential impact on Black patients: Implications for cancer clinical trial enrollment.

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.

Salvage radical prostatectomy.

Purpose Of Review: Salvage radical prostatectomy (sRP) is underutilized because of fear of historical high rates of peri-operative morbidities. However, there has been significant improvements in complication rates as well as oncologic outcomes in the recent years.

Recent Findings: Complication rates have significantly declined for both open and robotic approach in the past decade.

Clinic friendly estimation of muscle composition: Preoperative linear segmentation shows overall survival correlated with muscle mass in patients with nonmetastatic renal cell carcinoma.

Purpose: Sarcopenia is associated with decreased survival and increased complications in patients with renal cell carcinoma. Readily identifying patients with low muscle composition that may experience worse outcomes or would benefit from preoperative intervention is of clinical interest. Traditional body composition analysis methods are resource intensive; therefore, linear segmentation with routine imaging has been proposed as a clinically practical alternative.

Data regarding covariates significantly associated with sarcopenia and varying albumin statuses in patients with renal cell carcinoma.

Poor functional, nutritional, and muscle status is a significant negative predictor for surgical and survival outcomes in patients with cancer, including renal cell carcinoma. This dataset displays results from preoperative muscle composition analysis and albumin levels in a large cohort ( = 473) of patients undergoing surgery for renal cell carcinoma. Data was obtained from retrospective review of prospectively maintained databases and retrospective image analysis.

Extramammary Paget's disease: Updates in the workup and management.

Objective: Extramammary Paget's disease (EMPD) is a rare cutaneous malignant disease. Due to its rarity, there is a paucity of data regarding best treatment strategy. EMPD primarily affects apocrine gland-bearing skin areas such as the vulva, scrotum, and penis.

Prognostic Value of Sarcopenia and Albumin in the Surgical Management of Localized Renal Cell Carcinoma.

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.

Utility of ultrasonography in preoperative assessment of tumor thrombi in kidney cancer.

Introduction: This study examined the clinical accuracy of ultrasonography compared to magnetic resonance imaging (MRI) and intraoperative findings for evaluation of tumor thrombi level in patients with renal cell carcinoma.

Materials And Methods: We retrospectively identified 38 patients at our institution who underwent both ultrasonography and MRI before undergoing open radical nephrectomy with tumor thrombectomy between 2010 and 2019. We compared tumor thrombus level findings of both ultrasonography and MRI, as well as the diagnostic accuracy of each to intraoperative findings.

Compliance with Percutaneous Tibial Nerve Stimulation at a Tertiary Academic Center versus a County Hospital.

Objectives: To compare percutaneous tibial nerve stimulation (PTNS) compliance rate at a safety-net versus tertiary academic hospital and assess the impact of social determinants on compliance.

Methods: Retrospective cohort study of 133 patients at Grady Memorial Hospital and Emory Clinic from May 2015 to March 2020 who had refractory overactive bladder (OAB) and were prescribed PTNS.

Results: Grady patients were younger (age 58.

Case report: Important considerations for a renal mass on a solitary kidney in an adult with history of childhood wilms tumor.

Adult survivors of childhood Wilms tumor are at an increased risk of secondary malignant neoplasms. The presence of a solitary kidney further complicates clinical management in this population. Herein, we present the case of a 37 year old female with a history of childhood Wilms tumor presenting with a secondary renal neoplasm.

Resection of retroperitoneal tumors with inferior vena cava involvement without caval reconstruction.

Background And Objectives: Retroperitoneal tumors with involvement of the inferior vena cava (IVC) often require resection of the IVC to achieve complete tumor removal. This study evaluates the safety and efficacy of IVC ligation without caval reconstruction.

Methods: A retrospective chart review of patients who underwent IVC ligation (IVC-Ligation) and IVC resection with reconstruction (IVC-Reconstruction) at our institution between May 2004 and April 2021 was performed.
