Multiple Primaries (Pre-2007)--Ovary: Are mucinous cystic tumors of low malignant potential diagnosed in the left ovary in 12/2000 and in the right ovary in 7/2001 reportable as two primaries? See discussion.
Page 14 of the SEER Program Code Manual, 3rd Edition, states that bilateral retinoblastomas and bilateral Wilms tumor are always single primaries whether simultaneous or not. Does this apply to bilateral ovarian tumors as well?
For cases diagnosed 2001-2006:
Borderline tumors are not reportable to SEER as of 2001. If you are collecting them in your registry, use the following procedure: Exception 1 in the SEER Program Code Manual, 3rd Edition, responds to the issue of processing ovarian tumors. Simultaneously occurring ovarian tumors with a single histology are coded as one primary. In the case you cite, the right ovary primary occurred 7 months after the left ovary primary. This is not simultaneous, so it would be counted as a second primary.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
EOD-Extension--Meninges: How do you code extension for a malignant meningioma that invades into the adjacent brain tissue?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 60. Code 60 is defined as a brain tumor that extends into the meninges. It is also the appropriate code to use for a tumor that extends from the meninges to the brain.
EOD-Extension--Lung: How do you code extension for a lung tumor described on bronchoscopy as "obstructing the RUL and intruding into the right bronchus intermedius. Small tumor nodules distally in midline of anterior trachea wall"?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 85 [Metastasis] because the tumor nodules are discontinuous from the primary tumor.
CS Extension (Clinical)/SSF 3 (Pathologic Extension)--Prostate: Upon prostatectomy, the case was determined to be localized. There is no clinical assessment of the tumor prior to prostatectomy. Should clinical extension be coded to 99 [Unknown]? Please see discussion below. See discussion.
We have a prostate case that is clinically inapparent. There is no staging info at all, no biopsy done. Then the patient has a prostatectomy with a single 0.4cm focus of Adenoca gr 3+3.
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Yes, code CS Extension (clinical) as 99 [unknown]. The extension based on the prostatectomy is coded in Site Specific Factor 3 - Pathologic Extension.
EOD Clinical Extension--Prostate: Can you assign code 15 if there is no TURP and no physical exam? See discussion.
[Code 15 = Tumor identified by needle biopsy, e.g. for elevated PSA, (T1c)]
Prostate case: Elevated PSA, Prostate u/s: no abnormal findings, Prostate biopsy: adenocarcinoma. Can this be clinically coded as 15? According to Prostate EOD Coding Guide (6/2001), code 15 requires documentation that the physical exam was negative, but in this case, we have no physical info.
For cases diagnosed 1998-2003:
Code the EOD Clinical Extension field to 30-34 when there is no documentation saying that the physical examination was negative.
EOD-Extension--Breast: Should clinically mentioned "thickening" of the breast be ignored if the pathology report does not mention thickening or skin involvement? See discussion.
For cases diagnosed 1998-2003: Can clinical "thickening" of the breast be coded to 20-28 extension code when there is no mention of the thickening or skin involvement in the pathology report? How do we code cases when pathology reports don't support the clinical finding of skin involvement.
For cases diagnosed 1998-2003: Do not use code 20-28 when there is no preoperative treatment and the pathology report does not confirm skin invasion. The clinical diagnosis of skin involvement was not supported by the pathology report.
Scope of Regional Lymph Node Surgery/Radiation Sequence with Surgery/Date Therapy Initiated: Is the Scope of Regional Lymph Node Surgery field used to code date of first therapy and radiation sequence with surgery? See discussion.
Example: There is no primary site surgery and only an aspirate of a lymph node and the date of therapy is based on this procedure.
Yes, the Scope of Regional Lymph Node Surgery field is used to code the Date Therapy Initiated field and the Radiation Sequence with Surgery field.
Primary Site: How do we code site when endometrioid carcinoma arises in "endometriosis"?
Code the Primary Site to where the endometriosis implanted, which may or may not be the endometrium. Endometrioid carcinoma can arise in the ovary, endometrium and other internal genital sites. The site/histology edit for endometrioid and ovary has been removed from the SEER edit set.
Terminology/EOD-Extension--Prostate: How does SEER define the prostatic "apex"? See discussion.
Some pathologists define the prostatic apex as including the bottom third of the prostate whereas others regard only the bottom-most portion of the gland to be the apex.
SEER defines the apex as being the bottom-most portion of the gland. Apex means "narrowest part," which in the prostate would be the bottom-most portion of the gland.
Multiple Primaries (Pre-2007)/EOD-Extension--Bladder/Prostatic Urethra: When noninvasive papillary transitional carcinoma of the bladder and invasive papillary transitional cell carcinoma of the prostatic urethra are diagnosed at the same time, and staged by the pathologist as two primaries, should they reported as two primaries? If reportable as a single primary what site code should be used?
For tumors diagnosed prior to 2007:
No. This is one primary. Mucosal spread of noninvasive cancer from a hollow organ (bladder) into another hollow organ (prostatic urethra) is coded as a single primary. The prostatic urethra is seldom a primary site. The cancer usually starts in the bladder and spreads to the prostatic urethra via the mucosa. In this case the cancer in the prostatic urethra became invasive. Code primary site as bladder, NOS [C67.9].
For cases diagnosed 1998-2003: Code EOD Extension using the invasive information (prostatic urethra).
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
