Histology--Heme & Lymphoid Neoplasms: How is this field coded when the final diagnosis for excisional biopsy of two cervical lymph nodes shows classical Hodgkin lymphoma, histologic subtype cannot be determined, but the COMMENT section of the report indicates there are features of both lymphocyte rich and nodular sclerosis subtypes?
Per Rule PH28, code histology to 9650/3 [Classical Hodgkin lymphoma]. This rule states to code the non-specific (NOS) histology when the diagnosis is one non-specific (NOS) histology and two or more specific histologies.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms.

CS Site Specific Factor--Prostate: Can autopsy results also be used when coding SSF3, pathologic extension, given that the instructions only address the use of prostatectomy findings when coding this field?
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.
If the prostate cancer was diagnosed on autopsy, or the autopsy was performed within the staging timeframe (See 2004 SEER Manual, page 112), code SSF3 using the autopsy information.
Ambiguous Terminology/Reportability: How should the expressions "suspicious for but not diagnostic of" and "suspicious for the possibility of early invasive adenocarcinoma" be interpreted for reportability? Would the interpretation be different depending on the primary site?
For reportability, interpret "suspicious for but not diagnostic of" as NOT diagnostic of cancer.
The phrase "suspicious for the possibility of early invasive adenocarcinoma" may indicate that the case is in situ. If no further information is available, this is not reportable.
The site of the cancer diagnosis does not change the interpretation.
Grade, Differentiation--Bladder: If the only indication of grade for a bladder primary is "grade 2, NOS," and we do not know the grading system being used by the pathologist, is the numeric grade 2 coded?
See the General Coding Rules on page 92 of the 2004 SEER Manual for instructions about coding grade.
If the only information available is "Grade 2," assign code 2 [Grade II].
EOD-Lymph Nodes/EOD-Pathologic Review of Number of Regional Lymph Nodes Positive and Examined--Cervix: What codes are used to represent these fields for a cervix primary when the only information on lymph nodes is a CT of the pelvis showing "pelvic adenopathy" (no surgery was done)?
Code the EOD-Lymph Nodes field to 9 [unknown]. Code the Pathologic Review of Number of Regional Lymph Nodes Positive field to 98 [No nodes examined] and the Lymph Nodes Examined to 00 [No nodes examined] because there was no resection of the primary organs. Adenopathy, NOS, per SEER guidelines, is not coded as lymph node involvement
MP/H Rules--Breast: What histology code is used for lobular carcinoma, pleomorphic type?
For cases diagnosed 2007 or later, use rule H14 and code the histology 8520 [lobular carcinoma]. 8520 is the only ICD-O-3 code for lobular carcinoma. There are no codes for specific lobular types.
CS Extension--Head & Neck (Larynx): If a patient with cancer of the larynx is described as experiencing hoarseness, is that sufficient information to code "vocal cord fixation" or does that phrase need to be used?
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 vocal cord fixation when the only information available is "hoarseness." Vocal cord fixation must be documented on endoscopy. Hoarseness is a common presenting symptom of laryngeal malignancy.
2004 SEER Manual Errata/CS Site Specific Factor: Does SEER plan to incorporate the "Recording Tumor Markers in Collaborative Staging System Site-Specific Factors" document that was prepared for the CS Task Force Training Materials into the 2006 SEER Manual?
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.
There are no plans at this time to incorporate the Recording Tumor Markers document into the SEER manual. This document is not part of the Collaborative Staging manual. This is a stand-alone reference endorsed by the Collaborative Staging Steering Committee for use in coding site-specific tumor markers.
MP/H Rules/Histology--Thyroid: How many primaries are to be reported and what histology is to be coded for an anaplastic/undifferentiated thyroid carcinoma with sarcomatoid transformation likely arising in association with a papillary thyroid carcinoma? Thyroid contains one tumor: 12.5 cm in greatest dimension...almost completely replaces entire thryroid gland.
For cases diagnosed 2007 or later:
This is a single primary using rule M2; a single tumor is always a single primary.
The histology code for this case is 8260/3 [Papillary carcinoma of thyroid]. Begin with Histology Coding rule H8. Stop at rule H17 and code the histology with the numerically higher ICD-O-3 code.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Kidney: How many primaries, with what histology(ies) should be coded when nephrectomy pathology specimen shows separate tumors of "renal cell carcinoma [clear cell type]" and "renal cell carcinoma [granular cell type]"?
For tumors diagnosed prior to 2007:
Abstract two primaries. This is an example of two tumors with different histologic types in the same site. The right kidney has two separate tumors.
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.
