Which condition is classified as T2 in testis cancer?

In the classification of testicular cancer, the T classification signifies the extent of the primary tumor based on specific criteria outlined in staging systems like the AJCC (American Joint Committee on Cancer) system. T2 indicates a tumor that is larger than the T1 category and has specific characteristics.

A tumor classified as T2 involves testicular cancer that has penetrated the tunica albuginea (the fibrous covering of the testicle) and has spread to the epididymis but not beyond. This is important in understanding tumor progression and treatment protocols.

The choice indicating hilar soft tissue invasion is relevant as it suggests that the tumor has extended beyond the boundaries of the testicle into surrounding tissues, which aligns with the T classification. Such invasion is critical in determining the appropriate treatment strategy and predicting the prognosis.

On the other hand, the original tumor in option A does not specify the extent beyond the primary site and could either be in situ or localized, which does not fit the definitions used in the T classification. Retroperitoneal nodes involvement (option B) would actually pertain to regional spread and does not directly reflect the T classification, while stage IIIC (option D) describes a higher overall stage that includes T and N categories but does
