EOD-Extension--Head & Neck: In the absence of a clear surgical or pathologic description of how the salivary gland involvement relates to the head and neck primary, do we code the involvement as direct extension, further extension or metastasis? See discussion.
A composite resection of tonsillar mass and a modified radical neck dissection is performed. According to the pathology report: Squamous cell carcinoma involvement of tonsil with invasion of skeletal muscle. A separate specimen labeled "tumor" indicates a salivary gland is also involved with tumor. Neck dissection: 1 lymph node with metastasis.
For cases diagnosed 1998-2003:
In the absence of a clear statement that the gland was involved by direct extension, code the EOD-Extension field to 85 [Metastasis]. In this case, the salivary gland tumor was described as a "separate specimen" that contained the salivary gland. The extension does not appear to be contiguous for this case.
If the salivary gland involvement had been by direct extension, which would be assumed if there had been contiguous involvement of the gland with the primary site, then code the EOD-Extension field to 80 [Further extension]. If there had been direct extension, the surgeon probably would not have dissected through the tumor. The resection specimens would have been contiguous.
Multiple Primaries--Hematopoietic, NOS: When the SEER Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table indicates that a disease is not a new primary, but a pathologist or clinician states that it is a new primary, do we use the physician information or the table?
For cases diagnosed prior to 1/1/2010:If the physician clearly states that this is a new primary, submit it as a new primary. Otherwise, use the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases table.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Multiple Primaries (Pre-2007)--Bladder: Is a 1998 transitional cell carcinoma of the bladder, followed by a 2001 squamous cell carcinoma of the bladder reportable as a second primary?
For tumors diagnosed prior to 2007:
Yes. This case is reportable as a second primary. The rule in the SEER Program Code Manual says that invasive bladder cancers with histology codes 8120-8130 [papillary, transitional] are always coded as a recurrence and are an exception to the multiple primary rule. Squamous cell carcinoma [8070] is not a part of that exception.
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.
Grade, Differentiation--Breast: Is "histological grade" another way of saying "tubule formation" which would result in the following case having a Bloom-Richardson (BR) score of 7 which would be coded to grade 2? See discussion.
Final path diagnosis stated: Invasive ductal ca, histological grade 3/3, nuclear grade 2/3, mitotic index-moderate.
Yes. Code the Grade, Differentiation field to 2 [Grade 2] for this case. This case has a BR score of 7 which converts to a grade of 2. This pathologist seems to be describing the three parts of the BR system: tubule formation, mitotic activity and nuclear grade.
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 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.
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.
Histology: What code is used to represent the histology "endometrioid adenocarcinoma, villoglandular type"?
Assign code 8262/3 [Villous adenocarcinoma].
According to the WHO Classification of Tumours, Breast and Female Genital Organs (2003), villoglandular is one of four variants of endometroid adenocarcinoma. The corresponding ICD-O-3 code according to WHO is 8262/3.
EOD-Extension--Head & Neck: How much information is needed for a head and neck primary in order to code extension to localized versus unknown? What code is used to represent this field when the only information for a buccal cavity primary is a positive aspiration of the buccal mass?
For cases diagnosed 1998-2003:
Code the EOD-Extension to 99 [Unknown] for this case until more information is received. The available information does not describe the primary site and there is a complete lack of staging information.
Head and neck cancers spread early and often to nodes. Do not code the EOD-Extension to localized when the information is as limited as it is for this example.
EOD-Extension--Lymphoma: How do you code stage and EOD for an extranodal lymphoma with bilateral involvement of a paired site? See discussion.
For example, we frequently see cases of lymphoma occurring in bilateral orbits, or both lungs. This issue was discussed at a 1991 SEER meeting with the tentative answer being that lymphoma involving both organs of a paired site will be coded as stage I (e.g., both eyes or both lungs), as this would be contiguous disease. However, an extranodal lymphoma involving tissue of both limbs (e.g., soft tissue of both arms) will be coded as stage IV because this represents wide areas of involvement that have no connection.
For cases diagnosed 1998-2003:
Bilateral involvement of an extralymphatic paired organ is coded as involvement of a single extralymphatic organ or site for lymphomas. The EOD extension code would be at least 11 (Stage IE). Staging lymphomas of any site depends on whether one or more lymph node regions and/or extralymphatic organs are involved, and whether sites on one or both sides of the diaphragm are involved.
