EOD-Pathologic Extension--Prostate: If there is residual tumor in the distal urethra on prostatectomy, does that mean there is distal urethral margin involvement? See discussion.
2/98 Prostate bx: Right apex, right mid and right base positive for adenocarcinoma.
6/1/98 Radical retropubic prostatectomy w/ bilateral pelvic lymph node dissection. Pathology: Residual adenocarcinoma in distal urethra, right lateral sections and posterior lobe. Right apical margin, other margins, seminal vesicles, and 7 pelvic LN negative for malignancy.
For cases diagnosed 1998-2003:
For the example above, code the EOD-Pathologic Extension field to 34 [extending to apex] because most of the right side is involved.
The pathology report says all margins are free. The comment on residual tumor in the urethra, meant the first surgery did not completely remove tumor tissue from the urethra, it does not mean that tissue is at the margin.
Behavior Code--Bladder/Lymphoma: Should the "in situ" designation on a bladder primary's pathology report be ignored that states a diagnosis of "in situ lymphoma"?
Ignore the in situ designation. You cannot assign an in situ behavior code to a lymphoma primary. The term or designation of "in situ" is limited to solid tumors; carcinoma and/or cancer.
Surgery of Primary Site--Lung: What code is used to represent "photodynamic therapy" (PDT) for lung primaries? See Discussion.
PDT is not listed in the Surgery to Primary Site field codes for lung.
For cases diagnosed 2003 and later, code the Surgery of Primary Site field to 19 [Local destruction or excision, NOS] for lung primaries. Photodynamic therapy is a surgical procedure that results in the local destruction of tumor.
EOD-Size of Primary Tumor--Prostate: Should the size of tumor be recorded as 001 (focus) or the actual size when both are stated? See Discussion.
The pathology report from a TURP identifies a 3-mm focus of adenocarcinoma.
For cases diagnosed 1998-2003, code the EOD-Size of Primary Tumor field to 003 [3 mm]. The rule that says to code a focus or foci of tumor as 001 was developed for use when no tumor size is given.
