Reportability--Skin: Is a non-small cell carcinoma [8046/3] of the skin SEER reportable?
Non-genital skin primaries with a histology code equal to or less than 8110 are not reportable to SEER; therefore, the combination of C44_ and 8046/3 is not reportable.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Lung: How is histology coded for the tumor(s) that exist if a left upper lobe of lung resection final diagnosis states the patient has a moderately differentiated adenocarcinoma and the path indicates there are "multiple carcinoid tumorlets"?
For tumors diagnosed prior to 2007:
Histology is coded 8140/3 [adenocarcinoma]. This is one reportable tumor of the left lung. According to our pathologist consultant, the tumorlets are collections of cells which appear to be of neuroendocrine origin, but are not malignant.
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.
CS Lymph Nodes--Breast: Are small isolated tumor emboli occasionally found in lymph node capsular or pericapsular lymphatics sufficient to code as a lymph node metastasis?
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 "small isolated tumor emboli" in the pericapsular lymphatics detected by H&E that are less than 0.2 mm as 05 [Regional lymph node(s) with ITC's detected on routine H & E stains].
CS Site Specific Factor--Lymphoma: Can the International Prognostic Index (IPI) score be taken from a TNM form in the record? If so, what score would we code for "low" (0-1 points) and "high" (4-5 points)?
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.Yes, the IPI score from the TNM form can be used to code SSF 3. Without further information, code "low" as 000 [0 points]. Code "high" as 004 [4 points].
Priorities/CS Tumor Size--Breast: What is the priority order used in coding tumor size for this site when there is a larger 2 cm lesion noted on the PET scan and smaller sizes described in the pathology report as two malignant masses one measuring 0.8 cm and the second measuring 1.0 cm per the GROSS?
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 CS Tumor Size as 1.0 cm. The pathology report is the highest priority source for coding tumor size. When multiple tumors are present, code the size of the largest tumor.
CS Eval--Ovary: How is CS Mets Eval coded when the patient has positive pleural effusion confirmed by cytology?
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 CS Mets Eval for the example above 3 [path exam of metastatic tissue] assuming there has been no pre-treatment. Positive cytology is required for confirmation of pleural effusion for an ovarian primary.
2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes.
Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.
Primary Site/Priorities--Breast: When there are conflicting references to subsite in different reports, which report has priority? See Discussion.
The clinical site of the palpable mass is outer quadrant. The pathologist states inflammatory breast cancer located in the central breast. Should the site be coded to C501 for central breast, C509 for inflammatory breast ca, or C508 for outer quadrant?
Code the breast subsite from the pathology report (C501, central).
The priority order for coding subsite from conflicting reports is
1. Pathology report
2. Operative report
3. Physical examination
4. Mammogram, ultrasound
The primary site of inflammatory breast carcinoma is coded to C509 when there is no palpable tumor.
Histology--Lymphoma: How is "histiomonocytic lymphoma" coded?
For cases diagnosed prior to 1/1/2010:Assign code 9755 [Histiocytic sarcoma; True histiocytic lymphoma]. "Histiomonocytic" is not standard terminology, according to our expert consultant. However, 9755 is the best code to assign.
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.
CS Extension--Breast: How is this field coded when path describes dermal lymphatic invasion of the nipple? See Discussion.
Example
Multicentric infiltrating lobular carcinoma of left breast treated with MRM. Microscopic summary: Blood/lymphatic Vessel Invasion: present. Path final diagnosis: Angiolymphatic invasion present, including dermal lymphatic invasion in nipple. Micro: There is angiolymphatic invasion, including dermal capillary invasion identified in sections of the nipple.
The path report describes multiple breast tumors, none of which is located adjacent to the nipple.
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 [Invasion of subcutaneous tissue...] based on the final diagnosis on the path report. There is "dermal lymphatic invasion in nipple." In this case, the stage will be determined by the tumor size.
