MP/H Rules/Recurrence--Skin: If a pathologist does not review the August 2008 slides, how many primaries are accessioned for a patient diagnosed and treated for a dermatofibrosarcoma protuberans of the left upper inner arm in August 2008 who subsequently had a "recurrence" noted in October 2010 located in the scar of the original primary?
Abstract as a single primary: dermatofibrosarcoma protuberans [8832/3] of the left upper inner arm [C446] diagnosed in August 2008.
The rationale for this answer was provided by subject matter experts. The physician specialists for soft tissue and bone replied as follows:
Low-grade sarcomas tend to recur locally. Because this tumor recurred in same area, i.e. scar of prior surgery, and recurred in this period of time, this is a local recurrence. Dermatofibrosarcoma Protuberans is a low grade tumor which can recur many years following tumor excision.
Primary Site/CS Extension--Lymphoma: How should these fields be coded for a malignant lymphoma with spleen involvement, inguinal and iliac adenopathy, T12 lesion with bony destruction, and a paraspinal mass in lower lumbar region with extension into iliac fossa involving left psoas muscle and causing bony destruction?
For cases diagnosed prior to 1/1/2010, 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 primary site C496 [Connective, subcutaneous and other soft tissue of trunk]. When lymphoma is present in an extranodal organ/site and in that organ/site's regional lymph nodes, code the extranodal organ/site as the primary site. In this case, there is a soft tissue paraspinal mass at T12 extending into iliac fossa, left psoas muscle and bone. Lymph nodes are also involved. Assign CS extension code 21 [Direct extension to adjacent organs or tissues].
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.
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.
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.
First Course Treatment: If an "aromatase inhibitor" used as a complement to Tamoxifen is treatment, how should it be coded?
When an aromatase inhibitor is part of the planned first course of therapy, code it under hormone treatment.
When a change of drug is PLANNED, it is part of the same course even if subcategories change. This is the usual situation with Tamoxifen and aromatase inhibitor (for example: Femara). The switch to Femara is planned, so it is not a new course. When a drug change happens that is not planned, it is still the same course if both drugs are in the same category and subcategory. An unplanned drug change to a different subcategory would be a new course.
Reportability--Ovary: Is an "aggressive adult granulosa cell tumor with one of two lymph nodes positive for metastatic granulosa cell tumor" reportable?
Malignant granulosa cell tumor is reportable. The case described above is malignant as proven by metastasis to the lymph node.
CS Extension--Extramedullary Plasmacytoma: Under what circumstance would CS extension code 80 be used in a case of extramedullary plasmacytoma?
For cases diagnosed prior to 1/1/2010, 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 80 [Systemic disease] for extramedullary plasmacytoma involving more than one site. Use code 80 when extramedullary plasmacytoma is NOT single, solitary, unifocal, isolated, mono-ostotic or localized. Code 80 can also be used when the bone marrow is involved but the plasma cells are <10%.
Do not apply EOD instructions to CS.
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.
MP/H Rules/Histology--Gallbladder: What histology is coded for a tumor described as "90% high grade neuroendocrine ca, large cell type; and 10% low grade adenocarcinoma, conventional type"?
For cases diagnosed 2007 or later:
MP/H Rule H17 for Other Sites applies. Code the histology 8140 [adenocarcinoma].
The ICD-O-3 code for large cell neuroendocrine carcinoma is 8013 and the code for adenocarcinoma is 8140.
Reportability--Skin: Is a "basal cell carcinoma of the skin of the lip with focal skin appendage differentiation" reportable?
The histology code for basal cell carcinoma with skin appendage differentiation is 8098/3. Basal cell carcinomas (8090-8110) are not reportable to SEER. Skin appendage tumors are not reportable to SEER unless stated to be carcinoma or stated to be malignant.
According to our pathologist consultant, basal cell carcinoma with focal skin appendage differentiation is basal cell carcinoma which exhibits adnexal (appendage) features, but it is still basal cell carcinoma.
CS Extension--Lung: How is this field coded for a tumor in the right middle lobe with extension to the bronchus intermedius?
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 20
[Extension from other parts of lung to main stem bronchus, NOS
(EXCLUDES superficial tumor as described in code 11)
Tumor involving main stem bronchus greater than or equal to 2.0 cm from carina (primary in lung or main stem bronchus)].
A right middle lobe tumor that extends to the bronchus intermedius is one that is extending to the main stem bronchus from another part of the lung. The bronchus intermedius is the lower part of the main stem bronchus on the right. It is more than 2.0 cm away from the carina.
