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.

Summary from the NCI clinical trials planning meeting on next generation of clinical trials in non-muscle invasive bladder cancer.

The National Cancer Institute organized a virtual Clinical Trials Planning Meeting (CTPM) on 'Defining the next generation of clinical trials with combination therapies in non-muscle invasive bladder cancer (NMIBC)' led by the Bladder Cancer Task Force of the NCI Genitourinary Cancers Steering Committee. The purpose of this meeting was to accelerate advances in clinical trials for patients with high-risk NMIBC. The meeting delivered a multidisciplinary expert consensus on optimal strategies for next-generation clinical trial designs in NMIBC with prioritization of combination therapies.

Case report: Clinical and molecular features of renal gastrointestinal tumor.

While gastrointestinal stromal tumors (GISTs) often arise within the GI tract, it is well known that GISTs may also rarely emanate outside of the digestive system. Prior case reports have documented various primary sites in non-GI organs [extra-intestinal GIST (EGIST)], yet only one report has described a localized GIST of renal origin. Here, we describe a patient who presented with bilateral renal masses who was found to have a large unresectable renal GIST tumor treated with imatinib.

Interferon-γ/Janus kinase 1/STAT1 Signaling Represses Forkhead Box A1 and Drives a Basal Transcriptional State in Muscle-Invasive Bladder Cancer.

During progression, luminal muscle-invasive bladder cancer (MIBC) can transition to the aggressive basal-squamous (Ba/Sq) subtype. Reduced expression of forkhead box A1 (FOXA1) in the urothelium is a hallmark and driver of the Ba/Sq transcriptional state and squamous differentiation. Ba/Sq tumors are highly inflamed; however, the specific inflammatory pathways contributing to the Ba/Sq state are unknown.

Incidental early mixed epithelial and stromal tumor of the efferent testicular-ductular system of the genitourinary tract: A small case series with literature review.

Mixed epithelial and stromal tumors (MEST) are rare, hormone-driven tumors of the genitourinary tract composed of stromal and epithelial components. They are rarely encountered in men, and it is exceedingly rare to find MESTs in efferent testicular-ductular structures. The current literature focuses on symptomatic men with macroscopically evident tumors.
