Severity of effect considerations regarding the use of mutation as a toxicological endpoint for risk assessment: A report from the 8th International Workshop on Genotoxicity Testing (IWGT)

Environmental and Molecular Mutagenesis, EarlyView.
Abstract Exposure levels without appreciable human health risk may be determined by dividing a point of departure on a dose–response curve (e.g., benchmark dose) by a composite adjustment factor (AF). An “effect severity” AF (ESAF) is employed in some regulatory contexts.

Histologically verified penile lichen sclerosus—Incidence in Denmark over 26 years and long‐term risk of penile and non‐penile cancer

International Journal of Cancer, EarlyView.
What's New? About half of penile squamous cell carcinomas are causally associated with inflammatory conditions such as lichen sclerosus (LSc), but few large‐scale studies have assessed the risk of penile cancer in men with LSc. Here, the authors conducted a large nationwide study in Denmark to estimate the risk of penile and non‐penile cancer in men ...

The perioperative outcomes of retroperitoneal lymph node dissection in Germany for patients with testicular cancer: Results from the GRAND study

International Journal of Cancer, EarlyView.
What's new? This nationwide analysis explores the recent trends and perioperative outcomes of retroperitoneal lymph node dissection for testicular cancer, stratified by surgical approach, prior chemotherapy, and hospital caseload. Since 2005, the number of patients undergoing retroperitoneal lymph node dissection for testicular cancer has decreased ...

Testicular epidermoid cysts: a reevaluation

BMC Urology, 2019
Background Testicular epidermoid cysts (TECs) are rare benign testicular neoplasms. As TECs are rarely associated with germ cell tumours (GCTs), the understanding of biological behaviour and clinical management of TEC is unresolved.

MRI in the Histologic Characterization of Testicular Neoplasms

American Journal of Roentgenology, 2007
The purpose of our study was to investigate the potential role of MRI in the preoperative characterization of the histologic type of testicular tumors and, more specifically, to differentiate seminomatous from nonseminomatous testicular neoplasms.Twenty-one patients with histologically proven germ cell testicular tumors underwent MRI of the scrotum on ...

Pulmonary toxicity in children, adolescents, and young adults with testicular germ cell tumors: A population‐based retrospective matched cohort study

International Journal of Cancer, EarlyView.
What New? Testicular germ cell tumors are highly curable, but the treatments can have lasting impacts. As more young people are surviving these tumors, it is important to understand the lifelong toxicities of these treatments. Here, the authors evaluated the risks of acute and late pulmonary toxicities among children, adolescents, and young adults ...
