Ambiguous Terminology/Date of Conclusive Terminology: If there is an unknown date of diagnosis, should the Ambiguous Terminology field always be coded to 9 and the Date of Conclusive Terminology be coded to 99999999? See Discussion.
Scenario: Mammogram is suspicious for carcinoma, unknown date in 2007. A biopsy prior to admission to reporting facility is positive for carcinoma. Patient seen at reporting facility in June 2007 for treatment.
The purpose of the data item "Ambiguous Terminology" is to flag cases entered into the registry based on a diagnosis with ambiguous terminology. Because the case above was entered into the registry based on conclusive terminology, code Ambiguous Terminology to 0 [Conclusive term] and code Date of Conclusive Terminology to 88888888 [not applicable].
Histology--Lymphoma: How is a "lymphocytic lymphoma of follicular center cell origin" coded?
For cases diagnosed prior to 1/1/2010:Assign code 9690 [Follicular lymphoma, NOS]. According to the WHO Classification of Lymphoid tumors, follicular lymphoma is a neoplasm of follicle center B cells which has at least a partially follicular pattern.
Assign code 9695 for follicular lymphoma grade 1, 9691 for follicular lymphoma grade 2, and 9698 for follicular lymphoma grade 3.
For cases diagnosed 1/1/10 and later, 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)--Breast: How many primaries are to be abstracted when each of multiple breast "re-excisions" performed more than two months apart in 2006 demonstrate intraductal carcinoma and there is no mention of "recurrence"? See Discussion.
Right Breast
06/27/2002 exc bx, DCIS. Margins involved.
09/24/2002 re-exc, several foci of intraductal ca. Margins involved.
10/15/2002 re-exc, microfocus of DCIS
Radiation treatment started 11/18/2002.
Is this 1, possibly 2, or maybe 3 breast primaries because of the 2 month rule and no statement of "recurrence"? Based on SINQ #20000478, this would be at least 2, but possible 3 primaries. Based on SINQ #20021143, this would be 1 primary if the case were diagnosed from 1998-2003. The excisions appear to represent wider excisions of the same tumor.
For cases diagnosed prior to 2013:
For tumors diagnosed prior to 2007, this is one primary, assuming these are wider excisions of the same tumor.
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.
Reportability--Hematopoietic, NOS: The Abstracting and Coding Guide for the Hematopoietic Diseases, page 47, states to determine whether the physician is using the term myelodysplasia to describe bone marrow marrow malfunction or a neoplasic syndrome in order to determine reportability. What do we do when there is no information one way or the other?
For cases diagnosed prior to 1/1/2010:Without further information, the term "myelodysplasia" alone is not reportable. If a more definitive diagnosis is made later, the case may become reportable.
For cases diagnosed 1/1/10 and later, 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.
Grade, Differentiation--Bladder: Can grade be coded from the pathology report for a recurrent bladder cancer specimen? See Discussion.
In 2006 a TURB was done for bladder carcinoma diagnosed 10 years ago. Is grade always coded 9 on class 3 cases unless the original slides were reviewed?
Code grade from the original tumor; do not code grade from recurrence.
If the grade of the original primary tumor is specified, code it, regardless of class of case.
CS Tumor Size--Melanoma: How is this field coded when a smaller invasive and a larger in situ melanoma are reported as a single primary? See Discussion.
Patient has a 1.2 cm lesion right upper arm with a diagnosis of melanoma in situ. A second lesion on right wrist, 0.5 cm mole, has a diagnosis malignant melanoma, Breslow's 0.78, Clark's level III.
According to the 2007 MP/H rules, this is a single primary. Because the larger lesion is completely in situ, do you ignore it altogether and go with the smaller, invasive lesion? SEER Program Manual 2007, page 127, rule 4.l, states that when two lesions are reported as a single primary, code the size of the larger lesion, which in this case would be the in situ.
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.Code CS Tumor Size as 005 (0.5 cm). Code CS Tumor Size based on the invasive lesion.
Use the data items "Multiplicity Counter" and "Type of Multiple Tumors Reported as One Primary" to document that there are two tumors present, in situ and invasive.
Primary Site: Is an "angiosarcoma" stated as arising in the skin of the breast and treated with a mastectomy, coded to the primary site of skin or breast?
Code the primary site as skin of breast when skin of breast is documented as the site of origin.
According to the WHO classification of soft tissue tumors, the majority of angiosarcomas "develop as cutaneous tumors...less than one quarter present as a deep soft tissue mass."
CS Tumor Size/CS Extension--Prostate: Because prostatectomy results are excluded from the CS Extension field for prostate, is code 95 [No evidence of primary tumor] accurate to reflect bilateral lobe involvement of prostate cancer when it is incidentally found following a radical cystectomy for a bladder primary? Why must tumor size be 000 when the CS Extension code is 95?
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.Code prostate CS Extension to 99 [Extension unknown] and code CS Tumor Size according to the information available from the surgery.
CS Extension code 95 [No evidence of primary tumor] should be used only in that rare situation when the only evidence of disease is distant mets or lymph node involvement, no primary tumor found. That is why CS tumor Size must be 000 when CS Extension code 95 is used.
MP/H Rules/Histology--Colon: Regarding histology rule H21, is there a hierarchy or do you code the higher histology if there is an adenocarcinoma arising in a polyp and an adenocarcinoma in a villous adenoma?
For cases diagnosed 2007 or later:
If you arrive at H21 and have an additional decision to make regarding the use of 8210, 8261 or 8263, you must make another pass through the histology rules. The second pass will determine which of the two or three histology codes to assign. The answer will vary depending of the specifics of the case.
Example:
Transverse colon: Adenocarcinoma in an adenomatous polyp involving muscularis propria and adenocarcinoma in a villous adenoma involving subserosa of transverse colon. Start with rule H15 because there are multiple tumors. Stop at H21 -- code either 8210 or 8261. To decide between 8210 and 8261, make a second pass through the histology rules, starting again with H15. Stop at H20. Code the histology of the most invasive tumor, 8210 [Adenocarcinoma in adenomatous polyp].
MP/H Rules--Lung: Why the term "nodule" is not included as an equivalent term along with tumor, mass, lesion and neoplasm in the 2007 lung multiple primary rules?
Answer revised July 2008
For cases diagnosed 2007 or later:
For the purpose of applying the Lung MP/H rules, the word "Nodule" can be used interchageably with "Tumor," "Mass," "Lesion" and "Neoplasm." HOWEVER, this does NOT apply to casefinding or staging.
This revision will be added to the next version of the MP/H rules. Sinq question 20071028 will be revised.
