Primary Tumor (pT)
Tis Intratubular germ cell neoplasia (carcinoma 'in situ')
T1  Tumor limited to the testis and epididymis without
      vascular/lymphatic invasion; tumor may invade into
      the tunica albuginea but not the tunica vaginalis 
T2  Tumor limited to the testis and epididymis with
      vascular/lymphatic invasion, or tumor extending through the
      tunica albuginea with involvement of the tunica vaginalis 
T3  Tumor invades the spermatic cord with or without
      vascular/lymphatic invasion
T4  Tumor invades the scrotum with or without vascular/lymphatic invasion

The extent of primary tumor is classfied
after radical orchiectomy.

TX  Primary tumor cannot be assessed (if no radical
      orchiectomy has been performed, Tx is used)
T0  No evidence of primary tumor (e.g. histologic
      scar in testis)

Regional Lymph Nodes (N)
      or multiple lymph nodes, any one mass greater

      dimension
N3  Metastasis with a lymph node mass more than 5
      cm in greatest dimension

NX  Regional lymph nodes cannot be assessed
N0  No regional lymph node metastasis
N1  Metastasis with a lymph node mass 2 cm or less
      in greatest dimension; or multiple lymph nodes,
      none more than 2 cm in greatest dimension
N2  Metastasis with a lymph node mass more than 2
      cm but not more than 5 cm in greatest dimension;
