CS Tumor Size--Breast: Should this field be coded to 999 [Unknown] or 008 [0.8 cm tumor] when the tumor size is not provided on a stereomammotomy biopsy for an in situ malignancy and a subsequent excision demonstrates 0.8 cm tumor of residual in situ disease?
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 008 [0.8cm]. A mammotomy specimen is very small, so for this case, the residual tumor size is quite accurate. Size is not a critical data element for in situ breast cancer.
Multiple Primaries--Lymphoma: Is a diagnosis of mycosis fungoides followed a year later with a biopsy proven diagnosis of anaplastic large T-cell lymphoma stated to represent a transformation of the previous mycosis fungoides reportable as one or two primaries?
For cases diagnosed prior to 1/1/2010:
This is one primary. Code the histology according to the original diagnosis, mycosis fungoides. The physician states that this one disease process started as mycosis fungoides and progressed into lymphoma. A physician's statement has priority over other sources in determining the number of hematopoietic primaries.
In October 2006, a committee will begin working on multple primaries among hematopoietic diseases. The committee will provide further guidance on dealing with disease transformation and other issues.
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.
CS Lymph Nodes--Lung: Do modifying terms such as "borderline" affect whether lymph nodes are coded as involved when they are used in conjunction with the descriptors listed in Note 2 (i.e., mass, adenopathy or enlargement) for lung primaries? See Discussion.
Lung primary: CT states "borderline" enlarged hilar lymph nodes. Note 2 in the Lung schema under CS Lymph Nodes does not address qualifiers.
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.
Do not code the hilar lymph nodes as involved in this case. "Borderline" enlarged hilar lymph nodes do not meet the clinical criteria for enlargement.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Breast: For cases diagnosed in 2005, if a specimen contains an invasive 4.5 cm lobular carcinoma of the right breast and also has a tiny focus of intraepidermal tumors cells [Paget disease of nipple], how many cases should be abstracted and how should the histology field(s) be coded?
For tumors diagnosed prior to 2007:
There are two primaries in this example:
1. Invasive lobular carcinoma [8520/3]
2. In situ Paget disease of nipple [8540/2].
There is no combination code for lobular carcinoma and Paget disease.
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--Melanoma: Is the final diagnosis for an excisional skin biopsy of "compound nevus with severe cytoarchitectural atypia and regression" reportable if a re-excision may be clinically indicated because there is an "overlap of morphology between malignant melanoma and nevi with severe atypia, and there's evidence of regression"?
Compound nevus with severe atypia is not reportable unless also stated to be malignant melanoma or melanoma in situ.
2004 SEER Manual Errata/CS Lymph Nodes--Head & Neck: On page C-353, in the supraglottic larynx schema, there is no mention of Level IV nodes in the CS Lymph Node codes.
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.The CS Steering Committee is aware of this issue and is working to resolve it.
Reportability--Colon: Is a pathologically confirmed "tubulovillous adenoma with high grade dysplasia" reportable if clinical diagnosis at the time of the subsequent re-biopsy states "follow-up for colon polyps with ca in situ"? See Discussion.
SINQ 20000245 states that high grade dysplasia is not synonymous with behavior code 2 (in situ). However, the 2004 SEER manual states that "cases clinically diagnosed are reportable. If the physician treats a patient for cancer in spite of the negative biopsy, accession the case."
A pathologic diagnosis has priority over a clinical diagnosis. According to the pathologist, this case is not reportable. A re-biopsy is not treatment.
CS Site Specific Factor 6--Breast: If the tumor size for the breast is unknown, and it is unknown whether the tumor is mixed in situ and invasive or "pure", how is SSF6 to be coded? See Discussion.
The definition for SSF6 for breast changed from "Unknown if invasive and in situ components present, unknown if tumor size represents mixed tumor or a pure tumor" to an added clarification of "Clinical tumor size coded." Since the clinical tumor size is NOT coded, this does not fit.
The definition for 060 is "Invasive and in situ components present, unknown size of tumor (CS Tumor Size coded 999). Since it is unknown if the tumor is mixed, this definition does not fit either.
It seems that the revised (April 2005) definition for 888 has left a situation that cannot be 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.SSF 6 should be coded 888 in this case. SEER will make the CS task force aware of this situation.
Surgery of Primary Site--Lung: Is this field coded to 30 [Resection of lobe or lobectomy] or 33 [Lobectomy with mediastinal lymph node dissection] when a lobectomy specimen includes 2 AP window lymph nodes? See Discussion.
LUL lobectomy: 1.7cm apical tumor, DX=mod well diff subpleural SCC, with involvement of pleural surface. 3 peribronchial LN neg and 2 AP window LNs neg. Stage T2N0.
1. No lymph node dissection or sampling was stated to be done
2. The lobectomy specimen contained the LNs
3. Scope of regional LN surgery is coded
Would the surgery to primary site code 30 or 33?
Code surgery of primary site to 30 [Resection of lobe or lobectomy]. According to the information provided, there was no lymph node dissection in this case. The 2 AP window nodes were obtained as part of the lobectomy specimen.
Reportability--Melanoma: Is an excisional biopsy of the skin with a diagnosis on the pathology report of "Tumoral melanosis" reportable by itself or must there be a pathologist note, such as "Note: Unless proven otherwise, tumoral melanosis should be considered as a regressed melanoma", in order for it to be reportable? See Discussion.
Skin, left upper back, exc Bx: Tumoral melanosis. Note: Unless proven otherwise, tumoral melanosis should be considered as a regressed melanoma.
If reportable, do we report a diagnosis of tumoral melanosis without a similar note?
Tumoral melanosis (TM) alone is not reportable. It is not listed in ICD-O-3. TM can be associated with a regressed melanoma, but it can also occur with other cutaneous tumors. The case is reportable if there is a diagnosis of melanoma.
