Stage Information for Testicular Cancer

    Note: This Stage Information section has been updated to include information from the 7th edition (2010) of the American Joint Committee on Cancer's AJCC Cancer Staging Manual. The PDQ Adult Treatment Editorial Board, which is responsible for maintaining this summary, is currently reviewing the new staging categories to determine whether additional changes need to be made to other parts of the summary. Any necessary changes will be made as soon as possible.

    Definitions of TNM

    The American Joint Committee on Cancer (AJCC) has designated staging by TNM classification to define testicular cancer.[1]

    b The extent of primary tumor is usually classified after radical orchiectomy, and for this reason, apathologic stage is assigned.
    c Except for pTis and pT4, extent of primary tumor is classified by radical orchiectomy. TX may be used for other categories in the absence of radical orchiectomy.
    pTXPrimary tumor cannot be assessed.
    pT0No evidence of primary tumor (e.g., histologic scar in testis).
    pTisIntratubular germ cell neoplasia (carcinoma in situ).
    pT1Tumor limited to the testis and epididymis without vascular/lymphatic invasion; tumor may invade into the tunica albuginea but not the tunica vaginalis.
    pT2Tumor limited to the testis and epididymis with vascular/lymphatic invasion, or tumor extending through the tunica albuginea with involvement of the tunica vaginalis.
    pT3Tumor invades the spermatic cord with or without vascular/lymphatic invasion.
    pT4Tumor invades the scrotum with or without vascular/lymphatic invasion.
