Reportability/Primary Site--Head & Neck: If a wedge resection/shield resection is performed on the lower lip for SCCA and the path report refers to "lip, NOS" with no mention of vermilion border, is this case reportable?
Review the operative and pathology reports, and the physical exam for mention of "mucosal surface" (reportable) or "skin" (not reportable). If neither are mentioned, lip, NOS is reportable per the ICD-O-3 code of C009.
Cell indicator--Lymphoma: If the primary site for a lymphoma is stated to be the lymph nodes but there is no biopsy of a lymph node, can the immunophenotype designation for a lymphoma be coded based on a bone marrow or liver biopsy indicating "diffuse large B-cell lymphoma"?
For cases diagnosed prior to 1/1/2010:
The cell indicator or immunophenotype designation for lymphomas may be coded from pathology reports on tissue from bone marrow or liver when there is no tissue from the primary site. Code information on cell type from any available source.
See the Appendix C of the 2007 SEER manual, Coding Guidelines for Lymphomas, pages C-1055 to C-1056 for more information about coding this field for lymphomas.
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.
CS Extension--Brain and CNS: How is this field coded for a malignant tumor presenting as a confluent lesion over right parietal, posterior frontal and thalamic regions?
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 CS extension code 40 [Tumor crosses the midline; Tumor involves contralateral hemisphere; Tumor involves corpus callosum (including splenium)]
The thalamus is located between the corpus callosum and the cerebellum and brain stem. A supratentorial tumor extending to the thalamus involves the corpus callosum (extension code 40) but has not yet reached the cerebellum or brain stem. Code 40 applies, but code 50 or any higher code is not applicable in this case.
Reportability/Histology: Is this reporatable? If so, what is the correct histology?
2012 duodenal nodule biopsy, pathology positive for well differentiated neuroendocrine neoplasm.
Report this case as 8240/3. In this context, well differentiated neuroendocrine neoplasm seems to be a synonym for neuroendocrine tumor (NET) G1 (carcinoid). According to the WHO classification, "Neuroendocrine neoplasms of the duodenum comprise NETs..."
Reportability--Brain and CNS: Does a neurofibroma actually arise in peripheral nerve roots like a schwannoma even if it is referred to as a "C6-T1 intradural spinal cord tumor" and is therefore not reportable?
Schwannomas and neurofibromas of the peripheral nerves are not reportable. Schwannomas of the nerve root or spinal dura are reportable.
Reportability--Cervix: The SEER Program Code Manual lists CIN III and carcinoma in situ of the cervix as not being reportable for cases diagnosed in 1996 or later, but does not list "adenocarcinoma in situ" or "squamous cell carcinoma in situ." Are these histologies still reportable?
For primary site cervix uteri, only histologies with behavior codes of 3 [invasive] are reportable to SEER for all registries.
Some SEER registries have opted to continue to collect behavior codes of 2 [in situ] for cervix uteri primaries.
Primary Site/Histology (Pre-2007)--Rectum: How are rectal biopsies with the histology of "poorly differentiated carcinoma with mixed basaloid and squamous features" coded if, per the SEER site/histology validation table, the histology 8094/3 [basosquamous carcinoma] histology cannot be coded to the rectum for the primary site?
For tumors diagnosed prior to 2007:
Code primary site C209 [rectum] and histology 8094/3 [basosquamous carcinoma]. As of 6/9/2003, this is no longer an impossible site/histology combination.
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.
Histology--Leukemia: How is "T-Cell prolymphocytic leukemia, cerebriform (Sezary cell-like) variant" coded when the pathology report COMMENT states: The cerebriform (Sezary cell-like) variant accounts for about 5% of cases of T-cell prolymphocytic leukemia?
For cases diagnosed prior to 1/1/2010:
9834/3 [Prolymphocytic leukemia, T-cell type]. According to the WHO Classification of Haematopeietic and Lymphoid Tissue Tumours, cerebriform or Sezary cell-like is a variant form of T-cell prolymphocytic leukemia.
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.
Reportability--Brain: Is angiocentric glioma, WHO grade 1 of the right frontal lobe reportable? If so, how is histology to be coded?
Angiocentric glioma is reportable. The best histology code currently available is 9380/1 [glioma, NOS; uncertain behavior].
According to the WHO Classification of Central Nervous System Tumours, Angiocentric glioma has a behavior of /1. WHO defines it as an epilepsy-associated stable or slowly growing cerebral tumour primarily affecting children and young adults; histopathologicaly characterized by an angiocentric pattern of growth, monomorphous bipolar cells and features of ependymal differentiation.
CS Tumor Size--Unknown & ill-defined site: For an unknown primary site, should this field be coded to 000 [No mass/tumor found] or 999 [Unknown; size not stated; not stated in patient 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.Code the CS Tumor Size field to 999 [Unknown; size not stated; not stated in patient record] when the primary site is unknown.
There is a discrepancy in Part I of the CS Manual on page 27, rule 5g, which says that primary site C80.9 should be coded as 888 not applicable. The CS Steering Committee has decided that the last line about unknown and ill-defined sites should be deleted from rule 5g. This issue will be addressed in a CS errata to be distributed in July 2004.
