Oncologic outcomes of retroperitoneal lymph node dissection following first-line chemotherapy for metastatic non-seminomatous germ cell tumors.

Background: Post-chemotherapy retroperitoneal lymph node dissection (pcRPLND) is integral to multimodal treatment of patients with metastatic non-seminomatous germ cell tumors (NSGCT). We review pathologic and long-term outcomes of pcRPLND following first-line chemotherapy with a focus on residual mass size and primary tumor histology. Our goal was to identify new predictive approaches that can refine surgical indications.

Perioperative Complications and Omission of Ureteral Stents During Robot-Assisted Radical Cystectomy With Intracorporeal Ileal Conduit.

Purpose: Ureteral stents are commonly placed intraoperatively during radical cystectomy, although their efficacy in reducing complications is unproven. We compared clinical outcomes among patients undergoing robot-assisted radical cystectomy with intracorporeal ileal conduit (RARC-IC) with or without ureteral stents to determine if omission of ureteral stents affects postoperative complications.

Materials And Methods: All RARC-IC surgeries performed at our institution between November 2017 and June 2023 were reviewed.

Primary retroperitoneal lymph node dissection in clinical stage 2a/b non-seminomatous germ cell tumour.

Objectives: To reassess the role of primary retroperitoneal lymph node dissection (RPLND) in patients with marker-negative non-seminomatous germ cell tumour (NSGCT) clinical stage (CS) 2a, to explore results in patients with CS 2b and to evaluate surgical methods, recurrence, and adjuvant chemotherapy indications.

Materials And Methods: Data from 17 institutions were collected, comprising 305 men who underwent primary RPLND for CS 2 NSGCT. Regression analyses were conducted to predict histology in the RPLND specimen and disease-free survival (DFS).

Oncological Outcomes Following Robotic Postchemotherapy Retroperitoneal Lymph Node Dissection for Testicular Cancer: A Worldwide Multicenter Study.

Background And Objective: The feasibility and safety of a robotic approach for postchemotherapy retroperitoneal lymph node dissection (PC-RPLND) in testicular cancer have been demonstrated, but data on long-term oncological outcomes of this procedure are limited. Our aim was to evaluate oncological outcomes following robotic PC-RPLND in this setting.

Methods: This retrospective cohort study included consecutive patients with testicular cancer treated with robotic PC-RPLND at 11 academic centers worldwide between 2011 and 2023.

Long-term Clinical Outcomes of Patients With Negative Pathology (pN0) at Primary Retroperitoneal Lymph Node Dissection.

Background: Patients who undergo primary retroperitoneal lymph node dissection (pRPLND) for early-stage testicular cancer and have no cancer (pN0) found in the retroperitoneum are believed to have an excellent prognosis. However, some experience relapse, potentially due to limitations of current staging methods. We aim to describe long-term outcomes and relapse patterns among a contemporary cohort of patients found to be pN0 at pRPLND to identify opportunities for improved diagnostic approaches and optimal patient selection.

Perioperative Serum MicroRNA 371a-3p and 372-3p Levels in Patients with Clinically Localized Testicular Masses.

Background: MicroRNAs (miRNAs) show promise as blood-based tumor markers for germ cell tumors (GCTs), with miRNA-371-3p being the most studied. The marginal benefit of including other candidate miRNAs to aid with the management of testicular GCTs remains unclear.

Objective: To assess the performance of our combined miRNA assay (371a-3p and 372-3p) in patients with clinically localized testicular masses.

Long-term Outcomes of Regressed or "Burnt Out" Primary Testicular Germ Cell Tumors.

Objective: To review the presentation and long-term oncologic outcomes of patients with regressed ("burnt out") primary testicular germ cell tumors (GCT). Certain testicular GCT can present with complete regression of the primary tumor. It is not well established if this is associated with more aggressive disease or worse oncologic outcomes.

MicroRNA for Prediction of Teratoma and Viable Germ Cell Tumor after Chemotherapy.

MicroRNAs (miRNAs) are emerging as highly sensitive and specific markers for testicular germ cell tumors (GCTs) across the spectrum of disease. However, their utility in specific clinical scenarios requires further study. Here, we review the current evidence for miRNAs as tumor markers for the evaluation of treatment response in patients undergoing chemotherapy for the treatment of advanced testicular GCT.

Robotic post-chemotherapy retroperitoneal lymph node dissection for testicular cancer: A multicenter collaborative study.

Objectives: To evaluate the perioperative and oncological/functional outcomes of robotic post-chemotherapy retroperitoneal lymph node dissection for testicular cancer.

Methods And Materials: In this retrospective study, we included patients who underwent robotic post-chemotherapy retroperitoneal lymph node dissection at 7 academic centers between 2011 and 2021. Patients' characteristics, perioperative findings, as well as oncological and functional outcomes are reviewed.

Decreased Muscle Mass Prior to and Following Chemotherapy Predicts Morbidity in Testicular Cancer Patients Undergoing Post-Chemotherapy Retroperitoneal Lymph Node Dissection.

Introduction/background: The importance of nutritional status before oncologic surgery has been demonstrated in several solid malignancies. Testicular cancer primarily effects young men, and therefore clinicians may not consider sarcopenia as a factor in this population. We therefore sought to determine the impact of decreased muscle mass, measured by psoas muscle diameter, on outcomes in patients undergoing post-chemotherapy retroperitoneal lymphadenectomy (PC-RPLND) for metastatic germ cell tumors (mGCTs).

Pathologic fracture in metastatic kidney cancer: Identifying widening disparities and opportunity for quality improvement.

Background: Management and palliation of pathologic fracture (PFx) secondary to metastatic prostate (mCaP) and renal cancer (mRCa) is hospital resource intensive. Using a national all-payer database, we assessed the burden of PFx secondary to mCaP and mRCa nationwide. Admission rates, mortality, surgical fixation rates, and risk factors for high-cost admissions for pathologic fractures were assessed METHODS: National Inpatient Sample was queried from 2013 to 2015 for mCaP and mRCa admissions.

Minimally invasive retroperitoneal lymph node dissection for men with testis cancer: a retrospective cohort study of safety and feasibility.

Purpose: To describe the perioperative safety, functional and immediate post-operative oncological outcomes of minimally invasive RPLND (miRPLND) for testis cancer.

Methods: We performed a retrospective multi-centre cohort study on testis cancer patients treated with miRPLND from 16 institutions in eight countries. We measured clinician-reported outcomes stratified by indication.

Performance characteristics of F-fluciclovine positron emission tomography/computed tomography prior to retroperitoneal lymph node dissection.

Introduction: We aimed to determine whether anti-1-amino-3-F-fluorocyclobutane-1-carboxylic acid (F-fluciclovine) positron emission tomography/computed tomography (PET/CT) can accurately detect residual non-seminomatous germ cell tumor (NSGCT) prior to retroperitoneal lymph node dissection (RPLND). There is no reliable way to differentiate between fibrosis/necrosis, teratoma, and viable germ cell tumor in patients receiving post-chemotherapy RPLND. Functional imaging, including F-fludeoxyglucose (18F-FDG) PET/CT, has been disappointing.

The Impact of Race and Gender on 30-Day Urologic Surgery Complications.

Objective: To assess the effect of race and gender on complications after urologic surgeries.

Materials And Methods: The American College of Surgeons' National Surgical Quality Improvement Program data was utilized for patients undergoing urologic surgeries. Patient demographics and comorbidities were analyzed.

Simple Nephrectomy in a Tertiary Care Safety Net Hospital-Patient Characteristics, Causes, Cost, and Renal Function Implications.

Objective: To evaluate factors associated with simple nephrectomy at a safety net hospital with a diverse patient population and large catchment area. Simple nephrectomy is an underreported surgery. Performance of simple nephrectomy may represent a failure of management of underlying causes.

Occurrence and Natural History of Thyroid Cancer in Patients with Cowden Syndrome.

Introduction: Cowden syndrome patients are at an increased risk of developing differentiated thyroid carcinoma (DTC). There are limited studies of thyroid cancer biology within this population. We aimed to describe the frequency and progression of DTC in this population.
