Scientists have identified new gene faults and evolutionary patterns contributing to testicular cancer. Their findings offer profound insights into the development of the disease and into potential treatment strategies. Testicular cancer, though accounting for only about 1% of all cancers in men, is the most common cancer among those aged 15 to 44.
Each year, nearly 200 men in Ireland are diagnosed with this cancer and incidence rates have risen in recent years-;a trend also observed in Northern and Central Europe. Fortunately, testicular cancer is highly treatable, especially when detected early, with survival rates exceeding 90%. However, patients with the highest-risk disease face a significantly lower prognosis, with only around a 50% chance of survival despite extensive clinical trials, and existing chemotherapy treatments carry significant toxicities and associated side effects.
Using data from the 100,000 Genomes Project, led by Genomics England and NHS England, the scientists applied whole genome sequencing (WGS) to 60 patient samples to address key unresolved biological and clinical questions in testicular germ cell tumors (TGCTs). Their work has just been published in leading international journal Nature Communications . Among the key findings are: New potential cancer drivers in testicular cancer, including drivers specific to certain subtypes, which may help stratify patients based on their tumor characteristics A reconstruction of evolutionary trajectories of gen.
