EOD-Extension--Meninges: How do you code extension for a malignant meningioma that invades into the adjacent brain tissue?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 60. Code 60 is defined as a brain tumor that extends into the meninges. It is also the appropriate code to use for a tumor that extends from the meninges to the brain.
Behavior/Date of Diagnosis--Lung: If the term "Pancoast tumor, NOS" is malignant by definition, should the date of diagnosis be coded to the date of the clinical diagnosis when the clinical diagnosis is made prior to the histologic confirmation of the malignancy?
Yes, Pancoast tumor is by definition malignant. It is defined as a lung cancer in the uppermost segment of the lung that directly invades into the brachial plexus (nerve bundles) of the neck, causing pain. If a Pancoast tumor was identified on imaging prior to the biopsy, the date of diagnosis should be linked to the Pancoast tumor report.
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].
Recurrence (Pre-2007)--Colon: When there is no statement of recurrence on the abstract, is a colon tumor at the anastomosis site a recurrence of the previous colon cancer or a new primary?
For tumors diagnosed prior to 2007:
If the cancer at the anastamosis site is more than two months after the previous colon cancer, abstract as a separate primary.
If the cancer at the anastamosis site is within two months of the original diagnosis and the histologies are the same, do not abstract as a separate primary.
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.
Reportability/Ambiguous Terminology/Date of Diagnosis: If a "suspicious" cytology is reportable only when a later positive biopsy or a physician's clinical impression of cancer supports the cytology findings, is the Date of Diagnosis field coded to the later confirmation date rather than to the date of the suspicious cytology? Is a suspicious "biopsy" handled the same way?
Cytology reported as "suspicious" is not reportable. If the physician confirms the suspicious cytology by making a clinical diagnosis of malignancy, the Date of Diagnosis field is coded to the date of the clinical diagnosis, which may or may not be same date the cytology was performed.
Without supporting clinical documentation, the case will remain non-reportable and will not be submitted to SEER. The supporting documentation can be a physician's statement that the patient has cancer, a scan or procedure that identifies cancer, or a positive biopsy.
Suspicious "biopsies" are reportable according to SEER's list of ambiguous terms. Suspicious "cytologies" without supporting clinical statements are not.
Reportability/Breast: Is lobular carcinoma in situ (LCIS) reportable? The eighth edition, American Joint Commission on Cancer (AJCC) Cancer Staging Manual does not stage LCIS.
Yes, LCIS is reportable. Staging does not determine reportability. Follow the reportability requirements of your state and national standard setter. SEER reportability requirements are found in the SEER manual starting on page 5, https://seer.cancer.gov/manuals/2016/SPCSM_2016_maindoc.pdf
Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the pathology report states the morphologic features and immunophenotype of a low grade B-cell lymphoma are most compatible with lymphoplasmacytic lymphoma or marginal zone lymphoma?
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9591/3 [B-cell lymphoma, NOS] per Rule PH28 which states that one is to code the histology when the diagnosis is
specific histology
specific histologies
Heme DB Multiple Primaries Calculator documents the specific histologies and NOS are the
There is only one non-specific histology code mentioned, low grade B-cell lymphoma. This term is synonymous with B-cell lymphoma, NOS.
Per the Multiple Primaries Calculator, when comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9671/3 [lymphoplasmacytic lymphoma], it is the same primary. When comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9699/3 [marginal zone lymphoma], it is the same primary.

Primary site--Heme & Lymphoid Neoplasms: How is the primary site coded for a diagnosis of post-transplant lymphoproliferative disorder (PTLD) diagnosed on an inguinal lymph node biopsy with CT scan evidence of lymphadenopathy in the chest, abdomen and pelvis if the bone marrow is also involved?
Code the primary site to multiple lymph node regions, NOS [C778] per Rule PH21 when multiple lymph node regions, as defined by the ICD-O-3, are involved and it is not possible to identify the lymph node region where the lymphoma originated
In the Abstractor Notes section in the Heme DB for PTLD it states PTLD commonly involves lymph nodes, GI tract, lungs and the liver. This patient has extensive lymph node involvement. Rule PH26 states to code the primary site to the bone marrow when ONLY the bone marrow is involved; however, that does not apply in this case.

EOD-Size of Primary Tumor: Can you code the tumor size if you have the aggregate size given for two or more tumor masses?
For cases diagnosed 1998-2003:
No. Never code the aggregate size in the Size of Primary Tumor field when the pieces removed come from TWO OR MORE tumors. If there is a clinical statement regarding the size of two or more tumors, code this field to the size of the largest tumor.
The aggregate size can only be used to code the Size of Primary Tumor field when the PATHOLOGIST estimates the size of the tumor from the pieces of ONE tumor removed by the surgeon.
CS Tumor Size/CS Extension--Brain and CNS: How are these fields coded for a glioblastoma multiforme occurring in a 3.5 cm tumor in the parietal lobe and a 3.0 cm tumor in the occipital lobe?
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.
CS Extension code is 10 [confined to cerebral hemisphere]. Record the size of the largest lesion in CS Tumor Size. Both the occipital and parietal lobes are supratentorial and confined to the cerebral hemisphere with no mention of crossing midline or involvement of ventricles.
