Residence Near Agricultural Crops at Birth and Risk of Adult Testicular Germ Cell Tumors: A French Nationwide Case–Control Study Using Historical Aerial GIS Data

International Journal of Cancer, Volume 159, Issue 5, Page 1153-1166, 1 September 2026.
As the incidence of testicular germ cell tumors (TGCTs) rises, prenatal exposure to agricultural pesticides may represent an important risk factor. Here, geographic information system‐based measures of farmland proximity at birth were used as a proxy for early‐life pesticide exposure in France, a major pesticide consumer.

Microsatellite Instability‐High Somatic‐Type Malignancy Arising From a Primary Retroperitoneal Germ Cell Tumor: A Case Report

IJU Case Reports, Volume 9, Issue 5, September 2026.
ABSTRACT Introduction Immune checkpoint inhibitors have shown only limited clinical efficacy in germ cell tumors (GCTs), underscoring the need for predictive biomarkers such as microsatellite instability‐high (MSI‐high). We report a rare case of mixed‐type GCTs treated with chemotherapy, in which the somatic‐type malignancy (STM) component was found to
