20071048 MP/H Rules/Histology--Breast: If the abstractor only has the CAP protocol information from a pathology report and it does not include a "final diagnosis" label, which fields of the protocol are used to determine the histology and whether there is carcinoma in situ present in the specimen? For cases diagnosed 2007 or later, if the CAP protocol is used in lieu of a final diagnosis, use all of the information in the CAP protocol. 2007
20071117 MP/H Rules/Histology--Brain: How many primaries are reported and what is the histology for a single brain tumor described as a low grade astrocytoma at the time of the initial partial resection and a low grade glioneuronal neoplasm at the time of the subsequent total resection? See Discussion. On 4/20/07 a partial resection of a brain tumor is interpreted as low grade astrocytoma. Patient has a gross total resection on 8/13/07 with this diagnosis: low grade glioneuronal neoplasm (see comment). Comment: This case has been reviewed at ---. Dr. agrees with our interpretation (low grade glioneuronal neoplasm, possibly a dysembryoplastic neuroepithelial tumor).

For cases diagnosed 2007 or later, this is a single primary. A single tumor is always a single primary.

Assign histology code 9400/3 [Astrocytoma, low grade]. This diagnosis was not revised or amended based on the later surgery. It is possible that the malignant component was entirely removed during the first surgery.

Reportability/Chemotherapy--Hematopoietic, NOS: Is pyridoxine-responsive sideroblastic anemia (SA) reportable and is pyridoxine coded as chemotherapy for SA and refractory anemia with ringed sideroblasts (RARS)? See Discussion.

Patient has refractory anemia with ringed sideroblasts on bone marrow path. The physician mentions it might be due to pyridoxine deficiency. Per the SEER*Rx, pyridoxine (aka Vitamin B6) is not coded as treatment. What causes RARS and SA? Is pyridoxine treatment for either disease process? Or is the pyridoxine just treating one aspect of the anemia? The patient has no other treatment but this.

For cases diagnosed prior to 1/1/2010:Sideroblastic anemia (SA) is not reportable. SA is not the same as refractory anemia with ringed sideroblasts (RARS). Therefore, do not code pyridoxine administered for SA as therapy. If the patient had RARS that "might be due to pyridoxine deficiency," the replacement pyridoxine would not be coded as chemotherapy because it does not control or kill malignant cells. If the pyridoxine was successful in alleviating the refractory anemia, the RARS would be reversible and would not meet the criteria for a reportable blood disease; i.e. irreversible, clonal.

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.

20071111 MP/H Rules/Histology--Lung: How many primaries should be abstracted when a patient has an adenocarcinoma with bronchioalveolar-like features in the right upper lobe, adenocarcinoma in the right middle lobe and non-small cell carcinoma with clear cell features in the right lower lobe? See Discussion.

A RUL lung wedge resection and RML and RLL lobectomies were performed. The RUL resection showed invasive adenocarcinoma with bronchioalveolar-like features. Tumor size 9x.9x.8cm. The RLL lobectomy showed invasive non-small cell carcinoma with clear cell features. Tumor size 4.1x2.5x1.8cm. The RML lobectomy showed invasive adenocarcinoma. Tumor size 3.0x1.6x2.2cm.

Comment: Essentially three invasive tumors and a focus of bronchioalveolar carcinoma were identified in 3 specimens. All of the tumors appear somewhat histologically different. The larger tumors in the right upper and middle lobe were somewhat similar but still appear histologically different and therefore the pathologic staging is done based on all tumors being separate. The pathologic staging for this case is pT2(4) pN0 pMX.

What histology code and what site code are to be used on each abstract?

For cases diagnosed 2007 or later:

Abstract two primaries:

  1. C349 with histology coded to 8140 - invasive adenocarcinoma (RUL and RML)

  • C343 with histology coded to 8310 - invasive non-small cell carcinoma with clear cell features (RLL)

    • First, determine the number of tumors. There are three separate tumors in right lung in the example above:

    • RUL: invasive adenocarcinoma, bronchioalveolar-like features (8140, "-like" is not on the list of ambiguous terms used to code histology)

  • RLL: invasive non-small cell carcinoma with clear cell features (8310)

  • RML: invasive adenocarcinoma (8140)

    • Because there are three tumors, begin with rule M3 in the Multiple Tumors module. Stop at rule M11, multiple primaries for the tumor in the RLL (8310) compared to the tumors in the RUL and RML (8140 and 8140).

    Now evaluate the tumors in the RUL and RML using the multiple primary rules. Start at rule M3 and stop at rule M12, single primary.

    		20071015 CS Lymph Nodes/CS Mets at Dx--Melanoma: How are these fields coded if a sentinel lymph node biopsy reveals no malignancy but there is an aggregate of melanoma cells in the lumen of a large vein immediately adjacent to the lymph nodes?

    This question was answered by the CoC:

    Do not count this as regional metastatic disease since there is no evidence it is an established tumor. Stage this as a N0.

    		20071097 Multiplicity Counter--Thyroid: How is multiplicity counter to be coded for a thyroid cancer presenting as multiple foci? See Discussion. Thyroidectomy showed papillary thyroid carcinoma. Path diagnosis: tumor focality: multifocal. Path described 3 foci of tumor on each side. The main tumor mass in right thyroid was 1.5 cm. Smaller foci of tumor ranged in size from .1 cm to 1.0 cm. Per guidelines, "we still don't count foci as tumors for the purpose of these rules, even if there is more than one." The 1 cm tumor was probably macroscopic in size. Do we count it in the multiplicity counter? Do we count only the 1.5 cm main tumor mass?

    If the number of tumors is known, code the number in Multiplicity Counter. If foci are measured, include them in the multiplicity counter. If the only information available is "multiple foci" assign code 99.

    For the case above, code 06 in the multiplicity counter (3 tumors on each side).

    		20071080 First Course Treatment--Liver: Given that agents can be used that are not chemotherapy drugs, how should treatment be coded for a procedure called a "chemoembolization" when the agent used is not documented? This issue was discussed among the national standard setters and per the SEER website this issue has been resolved as follows: When "chemoembolization" is done but the agents used are not chemotherapy drugs, then treatment should be coded as "Other Therapy." See http://seer.cancer.gov/tools/codingmanuals/embolization.html 2007
    		20071001 CS Site Specific Factor/Melanoma: How is CS SSF1 (depth of invasion) coded for a melanoma that demonstrates dermal invasion to a depth of "less than .2 mm" be coded to 999 [unknown]? See Discussion.

    The path report says "superficial spreading malignant melanoma; 2 areas of papillary dermal invasion to depth of less than .2mm."

    The revised CS pages include codes for "less than" a certain tumor size, but these are not included in the depth of invasion SSF. Using 999 results in an unstageable melanoma, when we know it is "less than .2mm".

    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 SSF1 (depth of invasion) to 019 [.19mm]. For any case with an SSF1 code in the range of 001-100 mm, the T category will be determined using CS extension and SSF2 [ulceration]. All cases with an SSF1 code in the range of 001-100 mm will map to a T1 (either T1NOS, T1a or T1b).

    		20071035 CS Extension--Prostate: Should CS Clinical Extension always be coded to 99 [Extension unknown] for prostatic adenocarcinoma found incidentally during surgery for another primary or at autopsy? See Discussion.

    Patient had a cystoprostatectomy for bladder cancer. Pathology report states only 2 microscopic foci of prostate adenocarcinoma found on LEFT side of gland. Physician notes state patient has been followed for 4 years with a nodule in the RIGHT prostate and has refused biopsy despite rising PSA. There was no definite statement of suspected cancer.

    Should CS Clinical Extension be coded 99 because prostate cancer wasn't clearly stated to have been suspected until cystoprostatectomy? Or could we code the right-sided "nodule" as clinically apparent (CS Extension 20), even though path found tumor only on the left (which is how we would code a standard prostate case)?

    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 extension 99 [Extension unknown]. This prostate cancer was not clinically evident; it cannot be clinically assessed based on the information provided.

    Note: This is an unusual case. A DRE was performed and a nodule was palpated on the right that was not cancer. The other lobe is presumed to have been negative because it was not mentioned.

    		20071008 Histology (Pre-2007)--Breast: How is "invasive lobular carcinoma with signet ring cell features (95%) and ductal features (5%)" coded for a single tumor diagnosed prior to 2007?

    For cases diagnosed 1/1/04-12/31/06, code histology to 8524 [Lobular mixed with other types of carcinoma]. Assuming there is no mention of in situ, Histology Coding Rule 3 applies: Use a mixed histology code if one exists

    For cases diagnosed 2007-2014, 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.
