CS Extension--Prostate: Does the term "activity" in a Prostascint report indicate a clinically apparent tumor, tumor extension or tumor involvement for this primary site? (http://www.rtrurology.com/prostascint.htm)
CS Extension--Prostate: For a tumor that is clinically inapparent, but a biopsy from the prostatic apex is positive, is this field coded to 15 [Tumor identified by needle biopsy, e.g., for elevated PSA (clinically inapparent)]?
CS Extension--Prostate: Should CS Clinical Extension always be coded to 99 [Extension unknown] for prostatic adenocarcinoma found incidentally during surgery for another primary or at autopsy? See Discussion.
CS Extension--Retinoblastoma: When the degree of extension differs between the retinas, how is extension coded for simultaneous bilateral retinoblastoma?
CS Extension/CS Lymph Nodes--Breast: How would you interpret the phrase "axillary lymph node tissue, not clearly a lymph node" or the phrase "satellite nodule of invasive tumor, left axillary lymph node or chest wall tissue"? See discussion.
CS Extension/CS Lymph Nodes--Colon: What codes are used when large vessel invasion (V2 grossly evident) is stated to be present on a pathology report? See Discussion.
CS Extension/CS Lymph Nodes--Lung: How are these fields coded if a lobectomy path specimen indicates that two intrapulmonary lymph nodes are involved by direct extension from the primary tumor?
CS Extension/CS Mets at Dx--Corpus uteri: Is a microscopic metastasis in a cul-de-sac implant more appropriately reflected in the CS Extension field code 80 [Further contiguous extension; cul-de-sac] or in the CS Mets at Dx field code 40 [Distant metastasis]?
CS Extension/CS Mets at Dx--Lung: How are these fields coded for bilateral pleural effusion for a right lung primary? A code of 72 in the CS Extension field leads to a T4, but bilateral pleural effusion is M1. Should CS Mets at Dx be coded 39?
