Report Question ID Question Discussion Answer Year
20021048 EOD-Lymph Nodes: If chemotherapy or radiation is given prior to the excision of an involved lymph node, should the size of the metastasis within the lymph node be coded from the subsequent surgical pathology report? See discussion. For several sites, the size of the metastasis in an involved lymph node is integrated into the EOD-Lymph Node field. Should the size of the metastasis mentioned on the pathology report be ignored if the patient received radiation or chemotherapy prior to having the lymph node removed?

For cases diagnosed 1998-2003:

Record the size of a lymph node metastasis described in the pathology report for cases that had pre-surgical treatment. However, if both the pre-treatment and post-treatment size of the lymph node metastases are available, use the larger size when coding the EOD-Lymph Node field.

20020047 Scope of Regional Lymph Node Surgery/Radiation Sequence with Surgery/Date Therapy Initiated: Is the Scope of Regional Lymph Node Surgery field used to code date of first therapy and radiation sequence with surgery? See discussion. Example: There is no primary site surgery and only an aspirate of a lymph node and the date of therapy is based on this procedure. Yes, the Scope of Regional Lymph Node Surgery field is used to code the Date Therapy Initiated field and the Radiation Sequence with Surgery field. 2002
20021087 Multiple Primaries (Pre-2007)--Head & Neck: How many primaries are represented when a1998 invasive squamous cell carcinoma of the true vocal cord is followed by a 1999 diagnosis of in situ squamous cell carcinoma of the true vocal cord (called "recurrent" by the clinician), and in 2001 there is another invasive squamous cell carcinoma of the true vocal cord (no statement of recurrence)? Would your answer be any different if no statement of "recurrent" had been made in 1999?

For tumors diagnosed prior to 2007:

Code this case as two primaries, an invasive true vocal cord primary in 1998 and another invasive true vocal cord primary in 2001.

If there had been no statement of recurrence for the 1999 in situ diagnosis and the 1999 diagnosis was more than two months following the 1998 diagnosis, this case would be coded as three primaries.

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.

20020008 Surgery of Primary Site--Breast: Does the presence of axillary lymph node(s) in a "simple mastectomy" specimen impact the coding of the Surgery of Primary Site field for breast primaries?

Yes. Determine whether there is, in fact, at least a portion of axillary tissue present. If axillary lymph nodes (not internal mammary nodes) are present in the specimen, code the Surgery of Primary Site field to 51 [Modified Radical Mastectomy WITHOUT removal of uninvolved contralateral breast]. If there are no axillary lymph nodes present in the specimen, code the Surgery to Primary Site field to 41 [Total (simple) mastectomy WITHOUT removal of uninvolved contralateral breast].

EOD Clinical Extension--Prostate: Can you assign code 15 if there is no TURP and no physical exam? See discussion.

[Code 15 = Tumor identified by needle biopsy, e.g. for elevated PSA, (T1c)]

 Prostate case: Elevated PSA, Prostate u/s: no abnormal findings, Prostate biopsy: adenocarcinoma. Can this be clinically coded as 15? According to Prostate EOD Coding Guide (6/2001), code 15 requires documentation that the physical exam was negative, but in this case, we have no physical info.

For cases diagnosed 1998-2003:

Code the EOD Clinical Extension field to 30-34 when there is no documentation saying that the physical examination was negative.

20021030 Grade, Differentiation--All Sites: Why was the decision made not to code all "3-component differentiation systems" the same way that Bloom-Richardson is coded? For example, SEER codes a low grade BR to 1 for the Differentiation field and a low grade for other grading systems to 2. See discussion. Our Pathologist Consultant agrees with SEER's guideline to code the Bloom-Richardson and B&R modifications of low, intermediate and high to 1, 2 and 3 respectively and thinks all 3-component systems should be coded that same way because it better represents the differentiation of the tumor. In his opinion, coding all other 3-component systems to a differentiation of 2, 3 and 4 respectively, is overstating the degree of differentiation. The rules for coding histology are approved and used by all of the major standard setters through agreements reached in the NAACCR Uniform Data Standards Committee. This issue is under review by our medical advisors and a special committee. Changes will be taken to the Uniform Data Standards Committee for review and approval. 2002
20021106 Histology (Pre-2007)/Diagnostic Confirmation: What code is used to represent the histology that initially presents on uterine curettage as a hydatidiform mole and after pulmonary metastases develop a month later, the clinical diagnosis is "metastatic gestational trophoblastic disease"?

For tumors diagnosed prior to 2007:

Code the Histology field to 9100/3 [Choriocarcinoma]. Gestational trophoblastic neoplasia includes the diagnosis of choriocarcinoma.

Code the Diagnostic Confirmation field to 8 [Clinical diagnosis only] based on the information above. However, if imaging, direct visualization, or another method identified the pulmonary metastases, then code the Diagnostic Confirmation accordingly.

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.

20021018 First Course Treatment--Prostate: How do you code "watchful waiting" in these fields for prostate primaries?

For cases diagnosed 1/1/2003 and later: When "watchful waiting" is the first course of therapy for prostate cancer, code the case as follows:

Date Therapy Initiated: 000000

Surgery of Primary Site: 00

Scope of Regional Lymph Node Surgery: 0

Surgical Procedure of Other Site: 0

Reason for No Cancer-Directed Surgery: 1

Radiation: 0

Chemotherapy: 00

Hormone Therapy: 00

Immunotherapy: 00

Hematologic Transplant and Endocrine Procedures: 00

Other Cancer Directed Therapy: 0

Multiple Primaries--Lymphoma: How many primaries should be reported when a 5/99 diagnosis of stage III follicular large cell lymphoma [9698/3] of the conjunctiva [C69.0] is followed with a 6/01 diagnosis of small cleaved lymphoma [9591/3] of the breast [C50.9]? See discussion.

The Lymphatic and Hematopoietic Diseases folding table states that this should be one primary, but is this true when they are both extralymphatic in origin?

For cases diagnosed prior to 1/1/2010:Report as two primaries if that reflects the medical opinion for this case. The table is a guide, but does not overrule the clinician's opinion. These extranodal lymphomas are diagnosed in two different sites more than 2 months apart. They are listed as the same primary in the folding table because 9591/3 is generally a non-specific term and 9698/3 is a more specific cell type. If both histologies were diagnosed in the same organ or tissue, this is the same primary. However, the primary sites in this example are distinctly different.

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.

20021044 Histology (Pre-2007)/Grade, Differentiation: Can histology and/or grade be coded from a metastatic site? See discussion.

Example 1: No pathology specimen is available from the primary site for a lung primary. Rib biopsy demonstrated "anaplastic adenocarcinoma."

Example 2: Lung tissue biopsy revealed "poorly differentiated non-small cell carcinoma" for a lung primary. Pleural effusion cytology was consistent with "adenocarcinoma".

For tumors diagnosed prior to 2007:

Example 1: Code the Histology and Grade, Differentiation fields to 8140/39 [adenocarcinoma, NOS, grade not stated]. Because there was no microscopic examination of tissue from the primary site, the histology may be coded from the microscopic examination of the tissue from a metastatic site. Do not code grade from a metastatic site regardless of whether the involvement of the metastatic site is by direct extension or by discontinuous metastases.

Example 2: Code the Histology and Grade, Differentiation fields to 8046/33 [non-small cell carcinoma, poorly differentiated]. Because there is a microscopic examination of tissue from the primary site, that information should be used to code histology rather than a cytology of a metastatic site.

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.
