20071096 Multiplicity Counter--Prostate: How is multiplicity counter to be coded for a clinically inapparent prostate cancer for which sextant needle biopsy cores on left and right sides are positive for adenocarcinoma? See Discussion.

Prostate cancer typically presents as multifocal diffuse disease. The coding exercise in the MPH rules presentations coded prostate cancer as one tumor.

Reference: SEER Training Web Casts - Other Sites Rules Practicum

 Code the number of tumors present if known. This information can be taken from any part of the record, including imaging and prostatectomy. If the only information available is "diffuse," or "multifocal," assign code 99. Do not assume there are multiple tumors just beacause there are multiple biopsies. When there is no information about the number of tumors, code Multiplicity Counter to 99 and Type of Multiple Tumors to 99. 2007
20071066 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.

20071110 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.

20071009 MP/H Rules/Multiple Primaries/Laterality--Brain and CNS: How many primaries are to be abstracted and how is laterality to be coded for two meningiomas, one occurring at the midline and the other in the right termporal region? See Discussion. MRI of the brain shows two meningiomas: One is stated to be 'midline' (laterality code 9) and one is stated to be in the 'right' temporal region. The rules state if same site (C700), same histology & laterality is same side or one side unknown, then abstract as single primary. Based on this, the MRI findings would be one primary, but how should laterality be coded? For cases diagnosed 2007 or later, abstract two primaries. The lateralities of both meningiomas are known. Right (code 1) and midline (code 9) are different lateralities. 2007
20071128 MP/H Rules--Urinary: How many primaries are abstracted when a patient has a May 2000 invasive papillary transitional cell carcinoma of the bladder, a November 2004 invasive papillary transitional cell carcinoma of the right ureter and a May 2007 urothelial carcinoma in situ of both the left and right ureters?

For cases diagnosed 2007 or later:

Using the pre-2007 multiple primary rules, the PTCC of the bladder in 2000 and the invasive TCC of the right ureter in Nov. 2004 would have been abstracted as separate primaries.

Use the 2007 MP/H rules to evaluate the May 2007 diagnosis. Start with rule M3. Stop at rule M8. The May 2007 diagnosis is the same primary.

Rule M4 does not apply because of the 2000 bladder primary. A clarification will be added to M4 to stress that for the urinary rules, any urinary tumor up to the present point in time is counted when applying this rule.

20071098 Multiplicity Counter/Date of Multiple Tumors/CS Tumor Size--Lung: How are these fields to be coded when work-up of a malignancy spans a couple of months and reveals developing nodules? See Discussion. Example: Chest CT on 4-26-07 reveals 2.2 cm mass in lingula, left lung, consistent with lung malignancy. Biopsy on 5-18-07 shows non-small cell carcinoma. PET scan on 6-6-07 shows left upper lobe mass consistent with known non-small cell lung carcinoma. Second developing mass increasing in prominence since 4-07 in periphery of left upper lobe, approximately 3.6 cm which may represent intrapulmonary mets or second primary neoplasm. At least 3 additional intrapulmonary nodules have developed since 4-07, two in the left upper lobe and one in the right upper lobe, suspicious for mets.

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.Multiplicity Counter/Date of Multiple Tumors

Apply the multiple primary rules first and record the number of tumors determined to be a single primary in Multiplicity Counter. Record the corresponding date in Date of Multiple Tumors. These data items may be updated once if future tumors are determined to be the same primary as the initial diagnosis.

CS Tumor Size

Include information gathered through

  • completion of surgery(ies) in first course of treatment OR

  • all information available within four months of the date of diagnosis in the absence of disease progression

    • WHICHEVER IS LONGER.

    Metastasis known to have developed after the diagnosis was established should be excluded.

    		20071120 Surgery of Primary Site--Breast: Should code 51 (Modified radical mastectomy without removal of uninvolved contralateral breast) be used when a patient has excisional biopsy (22) and axillary dissection followed by a simple mastectomy without removal of uninvolved contralateral breast (41) as part of the first course of treatment?

    Assign code 51 or 52 if a patient has an excisional biopsy and axillary dissection followed by a simple mastectomy during the first course of therapy. Code the cumulative result of the surgeries, which is a modified radical mastectomy in this case.

    SEER collects only one surgery code per case. Code the most invasive, extensive or definitive surgery in Surgery of Primary Site.

    		20071105 Multiple Primaries/Histology--Lymphoma/Leukemia: How many primaries and what histologies are coded when a path diagnosis for a cervical/neck mass demonstrates classical Hodgkin's lymphoma on a background of chronic lymphocytic leukemia?

    For cases diagnosed prior to 1/1/2010:Hodgkin disease and chronic lymphocytic leukemia are separate primaries according to our current instructions. Abstract and code them separately.

    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.

    		20071065 MP/H Rules/Multiplicity Counter--Lung: If metastatic tumors are not counted in this field, should the multiplicity counter be coded to 01 for a case with a primary left lower lobe of lung tumor with a satellite tumor in the left upper lobe?

    For cases diagnosed 2007-2013:

    No, code multiplicity counter to 02 [two tumors present]. According to the multiple primary rules, these two lung tumors are reported as a single primary. Record the number of tumors reported as a single primary in Multiplicity Counter.

    Multiplicity Counter no longer required by SEER as of 1/1/2013.

    		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.
