Inhibition of HMGA2 Leads to Reduced Cell Proliferation and Increased Apoptosis in Human Embryonal Carcinoma Cell Lines

Andrology, EarlyView.
ABSTRACT Background The most prevalent solid tumors in young men are testicular germ cell tumors (TGCTs), and embryonal carcinoma is the most common subtype among non‐seminomatous germ cell tumors (NSGCTs). Despite the excellent cure rates of cisplatin‐based chemotherapy, resistance develops in 15%–30% of patients with metastatic cancer, which results ...

A Unified Machine Learning Model for Relapse Prediction in Clinical Stage I Testicular Cancer

Andrology, EarlyView.
ABSTRACT Background Approximately one‐fourth of patients with clinical stage I testicular cancer relapse. For decades, risk stratification has been based on different tumor characteristics for seminomas and non‐seminomas. Previous studies primarily used Cox proportional‐hazards models and included only a limited number of variables.

T Cell Microenvironmental Impacts and Therapeutic Opportunities: Application to Human Testicular Germ Cell Tumors

Andrology, EarlyView.
ABSTRACT Testicular germ cell tumors (TGCT) are the leading malignancy in adolescent and young adult males, yet the immunological and cellular mechanisms governing their tumor microenvironment (TME) remain poorly understood. Here, we present a comprehensive review of TGCT pathobiology with a focus on the immune landscape, particularly the role of tumor‐
