Testicular Cancer

Neurofibromatosis type 1 (NF1) is a genetic disorder that increases the risk of various tumors. However, its association with testicular germ cell tumors (GCTs) is rare. We report a case of metastatic GCT in an NF1 patient treated with precision medicine.

Testicular germ cell tumours (TGCTs) are the most common malignancy among young men, and their rapidly increasing incidence suggests a role for modifiable risk factors. The role of increasingly prevalent cannabis use, particularly during developmental periods before biological maturation, in TGCT etiology remains unclear.

Testicular cancer is the most common cancer in young adult men, and its incidence is increasing globally, with testicular germ cell tumors (TGCT) being the most frequent subtype. These tumors show remarkable sensitivity to cisplatin, but there is a small subset of patients that develop resistance to the therapy, experiencing low quality of life and having no treatment options.

Testicular seminoma predominantly affects young men, and while photon-based radiotherapy achieves excellent disease control, concerns about late effects, including secondary malignancies, have driven interest in proton beam therapy (PBT) as a way to improve dose conformality and spare normal tissue.

Intermediate-risk and poor-risk nonseminomatous germ cell tumors (NSGCTs) have inferior survival outcomes compared with earlier stages. This study reports the survival outcomes and proposes a prognostic reclassification to identify the poorest risk subset within these groups.

Testicular sex cord-stromal tumours (TSCSTs) are rare neoplasms that arise from (or show differentiation to) elements derived from the sex cords or intertubular stroma. The current classification (World Health Organization, 2022) is based almost entirely on morphology, with many tumour types such as granulosa cell tumours being defined based on their resemblance to ovarian counterparts.

To evaluate functional and oncological outcomes of testis-sparing surgery (TSS), particularly in selected patients with small testicular masses (STMs), including those with a normal contralateral testis and germ cell tumors.

Testicular germ cell tumors (TGCTs) have long been considered a disease primarily of young men, typically affecting those between 15 and 45 years of age. However, over the past few decades, there has been a meaningful epidemiological shift with a growing proportion of TGCT diagnoses in older men.

Can cryopreserved primary testicular somatic cells from childhood cancer survivors with severely decreased fertility potential be reprogrammed into human-induced pluripotent stem cells (hiPSCs) competent for efficient specification into early human germ cells?

Primary testicular somatic cells from cryopreserved testicular samples with severely compromised spermatogonial pools can be reprogrammed into hiPSCs using a non-genome-integrating, feeder-free approach and subsequently differentiated into human primordial germ cell-like cells (hPGCLCs) with high efficiency.

Germ cell tumors (GCTs) are the most common malignancies among young men. In Latin America and the Caribbean, including Chile, population-based data remain limited; however, mortality is consistently reported to be higher than that in other regions.
