20071042 MP/H Rules/Multiple Primaries--Breast: How many primaries are to be abstracted when two tumors occur in one breast and both are ductal with the smaller tumor representing tubular carcinoma [variant]? See Discussion.

Right breast partial excision: Two invasive foci, one measuring 0.2cm and the second measuring 0.5cm. Both lesions are ductal carcinoma with the smaller representing tubular carcinoma (variant).

The breast histology table does not list tubular as a type of ductal, however, the pathologist states ductal carcinoma, tubular variant.

 For cases diagnosed 2007 or later, this is two primaries of the right breast, using the 2007 MP/H rules. For the purposes of the 2007 rules, tubular is not a specific type of duct. Duct carcinoma (8500) and tubular carcinoma (8211) are different at the second digit of the histology code. Rule M12 applies, making these separate primaries. 2007
20071039 Histology--Hematopoietic, NOS: If an initial bone marrow diagnosis is "...more compatible with CMML/MPD" and within three months the final diagnosis per the oncologist is "MPD/CMML with acute myeloid leukemia transformation," is histology coded to CMML or AML? See Discussion.

09/06 BM Bx elsewhere was "compatible with MDS but more compatible with CMML/MPD" per MD notes.

10/06 BM Bx "...poor prognosis MDS, best classified as RAEB-2"

11/06 BM Bx "myeloproliferative CMML with leukemic transformation"

(on evaluation for BMT)

12/12/06 Pt was admitted with rapidly progressive disease & was started on chemo to try to get into remission for BMT. Final dx by oncologist is "MPD/CMML with acute myeloid leukemia transformation".

For cases diagnosed prior to 1/1/2010:Code CMML for this case. Code the histology at initial diagnosis. This patient had rapid progression, but the initial diagnosis was "more compatible with CMML/MPD."

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.

20071093 Reportability--Brain and CNS: In addition to Schwannoma, are there additional types of benign tumors that arise in peripheral nerves along the spinal cord that are not reportable? See Discussion.

Are neuroepitheliomatous neoplasms such as ganglioneuroma, gangliocytoma, ganglioglioma occurring along the spinal cord reportable? Are nerve sheath tumors such as neuroma occurring along the spinal cord reportable? Angioma?

Reference: SINQ 20051071; Primary Central Nervous System Tumors, NPCR Training Materials 2004

Reportability depends on the location of the tumor. Tumors in the following sites are reportable:

  • C700 - C709

  • C710 - C719

  • C720 - C729

  • C751 - C753

    • Benign and borderline tumors of the peripheral nerves (C47_), including peripheral nerves along the spinal cord, are not reportable.

    Please note: spinal schwannomas arising in the nerve root or spinal dura are reportable.

    		20071075 Flag: For cases diagnosed prior to 2001, how is the ICD-O-3 Conversion Flag set if the ICD-O-2 and ICD-O-3 histology and behavior fields are both directly coded, as registrars in this region are instructed to do when submitting late cases, and as a result no conversion is necessary? Is it to 0 [Morphology (Morph--Type&Behav ICD-O-3 originally coded in ICD-O-3)] or Blank [Not converted]?

    Assign code 3 [converted with review].

    In your scenario above, ICD-O-2 and ICD-O-3 are being independently coded which should yield the same result as converting the case and then reviewing it.

    Otherwise, if there is an ICD-O-3 code which differs from the ICD-O-3 code based on the conversion criteria, it will trigger an edit.

    		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.

    		20071081 CS Site Specific Factor--Lymphoma: Can the registrar calculate the International Prognostic Index (IPI) score from information found in the H&P or on the back of a TNM form for the SSF 3 field if the physician does not document it in the medical record?

    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.Record the IPI score in SSF3 when the score is documented in the medical record. If the score is not stated, do not calculate it.

    		 2007
    		20071017 CS Extension--Prostate: Can the phrase "hard, fixed prostate" be interpreted as clinical extracapsular extension and coded to 50 [extension or fixation to other structures]? See Discussion.

    Patient had a "hard, fixed prostate" with needle core bx positive for Gleason grade 4+5=9 adenocarcinoma extensively involving gland. PSA was 87.5. Lymphadenectomy showed 3 positive pelvic/obturator lymph nodes. No prostatectomy was done and no physician TNM staging documented.

    Do we need a specific clinical description of other organs to which the prostate is fixed in order to code CS Clinical Extension 50, or does the statement "hard, fixed prostate" qualify? If not, how would we code extension for this seemingly advanced cancer?

    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.Assign extension code 50 [extension or fixation to adjacent structures] based on the term "fixed." Fixation to a particular structure(s) does not have to be specified in order to use code 50.

    Do not use the statement "hard" to determine CS extension.

    		20071092 Reportability/Primary Site--Brain and CNS: Is a chondroma, NOS or a chondroblastoma, NOS that occurs in an intracranial site or along the spinal cord reportable? See Discussion.

    In ICD-O-3, chondroma and chondroblastoma are site-associated morphologies for bone. If a chondroma or a chondroblastoma occurs along the spinal cord, is this one of those situations where we can be quite comfortable with a default site to bone and not to spinal cord?

    Reference: ICD-O-3; Primary Central Nervous System Tumors, NPCR Training Materials 2004; SINQ 20021152

    Chondroma, NOS or chondroblastoma, NOS occuring in intracranial sites or along the spinal cord are not reportable.

    Chondroma, NOS and chonroblastoma, NOS are benign tumors of the bone itself, not the intracranial contents.

    		20071012 Reportability--Melanoma: Is a skin excision final diagnosis of "melanocytic tumor with uncertain malignant potential" reportable if the path COMMENT states the initial shave biopsy diagnosis was "melanocytic tumor with uncertain malignant potential [minimal deviation melanoma]"? See Discussion.

    SKIN, RIGHT FOOT, EXCISION: CHRONIC SCARIFICATION WITH RESIDUAL ATYPICAL MELANOCYTES IN THE DERMIS IDENTIFIED, BUT COMPLETELY EXCISED.

    Comment: The prior outside biopsy report indicates that the lesion was a melanocytic tumor of uncertain malignant potential (minimal deviation melanoma) measuring at least 2.5 mm in depth. There was apparently no in situ component. Special stains performed here are similar, with positive reactivity for Melan A and S-100. The cells are atypical, but there are reactive changes, making it impossible to accurately assess the true nature of the lesion in this biopsy. If this is a minimal deviation melanoma, it would be classified as a T3 (T3a since there is no description in the outside report of ulceration) lesion. The atypical melanocytes extend to a depth of 1.1 mm in this 2 mm deep biopsy, but are completely excised, both at the deep margin and at all of the peripheral margins (closest margin is superior, with clearance of 7 mm).

    PATH FROM INITIAL BIOPSY: Diagnosis: Rt dorsal foot, shave biopsy: Melanocytic tumor of uncertain malignant potential (see comment). Tumor depth at least 2.5mm Deep margin involved. Comment: As a primary lesion, I would favor that this represents a melanocytic tumor with indeterminate biologic potential also known as minimal deviation melanoma. The lesion does extend to the deep margin and wider excision is recommended.

    		 This case is not reportable. Based on the information provided, there is no definitive diagnosis of malignancy. 2007
    		20071070 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.
