Collaborative Staging--Lung: Given that the AJCC lung TNM is not applicable for a high grade sarcoma of this site, how do we code Collaborative Stage for this site/histo combination when the pathologist indicates a TNM stage of T2bN0M0=stage III, using AJCC Soft Tissue Sarcoma schema?
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.
Use the lung schema to code CS for sarcoma of the lung. Complete the CS information as best you can from the medical record WITHOUT using the TNM Soft Tissue Sarcoma staging form. Visceral sarcomas are specifically excluded from soft tissue sarcoma TNM staging and sarcomas are excluded from the TNM staging for lung.
Sarcoma is listed on the Histology Exclusion Table for lung. When a case is coded in Collaborative Staging and the histology is on the exclusion list, SEER Summary Stage 1977 and 2000 can be assigned. For these cases, TNM will not be calculated and displayed results will be "T NA N NA M NA and Stage Group NA".
Chemotherapy: If a physician does not document the reason chemotherapy was given concurrently with radiation therapy, should it be assumed to have been used as a radiosensitizer or radioprotectant and then, per SEER chemotherapy coding instruction 2, ignore coding the chemo agent as treatment?
Do not assume that a chemo agent given with radiation therapy is a radiosensitizer. Seek additional information.
Compare the dose given to the dose normally given for treatment. When chemotherapeutic agents are used as radiosensitizers or radioprotectants, they are given at a much lower dose.
Diagnostic Confirmation--Leukemia: How is this field coded when the clinician confirms that the diagnosis of CML is based on a combination of the clinical picture and positive cytogenetic studies?
Assign code 1 [Positive histology]. For leukemia only, assign code 1 for positive hematologic findings including peripheral blood smears, CBCs and WBCs.
Cytogenetics studies would have been done on blood. Therefore, histology provided diagnostic confirmation as it would with smear, bone marrow, or other special study of blood cells.
Reportability/Behavior--Hematopoietic, NOS: Is a "myelodysplastic/myeloproliferative disease, unclassifiable" coded to 9975 with a behavior code of 3 as indicated in the WHO blue book on "Tumours of Haematopoietic and Lymphoid Tissues" or is it not abstracted because it has a behavior code of 1 which means the case is not reportable?
For cases diagnosed prior to 1/1/2010:Code MDS/MPD U to 9975/3 [Myelodysplastic/myeloproliferative disease, unclassifiable]. Change the behavior code to /3 according to ICD-O-3 Rule F. The case is reportable.
The WHO book is more recent and gives a specific code for this new hybrid category of the WHO/REAL classification.
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.
Recurrence (Pre-2007)--Colon: When there is no statement of recurrence on the abstract, is a colon tumor at the anastomosis site a recurrence of the previous colon cancer or a new primary?
For tumors diagnosed prior to 2007:
If the cancer at the anastamosis site is more than two months after the previous colon cancer, abstract as a separate primary.
If the cancer at the anastamosis site is within two months of the original diagnosis and the histologies are the same, do not abstract as a separate 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.
Reportability--Breast: Is a biopsy proven squamous cell carcinoma of the breast nipple reportable if a subsequent areolar resection shows foreign body granulomatous reaction to suture material and no evidence of residual malignancy in the nipple epidermis?
Yes, this case is reportable. The primary site is C500 [nipple]. There was a diagnosis of malignancy on 2/15/06: "Positive for malignancy." Even though no residual malignancy was found in the later specimen, that does not disprove the malignancy diagnosed on 2/15/06.
CS Site Specific Factor--Breast: If there are two ER/PR tests, one positive and one negative, which result should be coded in the SSF fields 1 and 2? See Discussion.
SINQ #20021074 states that for cases up to 2003, if there are differences in ER/PR results, to code the positive findings over the negative findings. Does this hold true for coding SSF1 & SSF2 for breast?
Scenario: 10/19 Breast bx: ER + PR -; No date/specimen: ER/PR -; 12/3 Partial Mast: ER/PR +
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.
For cases diagnosed prior to January 1, 2007, according to the CS Steering Committee, record the pathologist's interpretation of the assay value for the most representative tumor specimen. This may require conversation with the pathologist when specimen size is not specified.
CS Extension--Lymphoma: If bilateral tonsils are involved with lymphoma, is it one or two regions of involvement and how is extension coded?
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.For cases diagnosed 1-1-08 and later: Assign CS extension code 10 [involvement of a single lymph node region]. Bilateral tonsils are one organ/site.
See Note 1 under CS Extension. Tonsil is coded the same as a lymph node region.
Reportability--Brain and CNS: Is benign neural tissue compatible with a glioneuronal hamartoma of the cerebellopontine angle reportable?
No. A glioneuronal hamartoma is not neoplastic and not reportable. See page 2 of the 2004 SEER Program Coding and Staging manual for the list of reportable brain/CNS tumors. There is no ICD-O-3 code for hamartoma.
