EOD-Size of Primary Tumor--Breast: How would this field be coded, using the revised and expanded breast code, for a lesion described as "1.3 cm infiltrating ductal carcinoma, associated DCIS?"
For cases diagnosed 1998-2003: Code size of primary tumor as 013. The phrasing suggests that the infiltrating ductal carcinoma measures 1.3 cm. DCIS is also present, but no size mentioned.
Date of Diagnosis/Diagnostic Confirmation: How are these fields coded when a physician statement of diagnosis predates a positive biopsy? See Description.
A mass seen on EGD with negative biopsy 12/28/01. Needle core biopsies 1/14/02 were diagnostic of GIST. Gleevec treatment was initiated 2/02, and in discharge summary 5/27/02, the physician says the GIST was diagnosed on EGD.
Code the date of diagnosis as 01/2002. Code the diagnostic confirmation as positive histology. EGD revealed a "mass." Biopsies of the "mass" seen on EGD were negative before January 2002.
Surgery of Primary Site--Breast: How is this field coded when a patient has a reduction mammoplasty (for macromastia) and within the pathology specimen there is an incidental finding of carcinoma?
Code this reduction mammoplasty to the code which best fits the amount of tissue removed. Read the operative report carefully. Code as a partial mastectomy, skin- nipple- areola-sparing mastectomy, or total (simple) mastectomy. Use text fields to record the details.
Reportability--Appendix: Is an appendiceal carcinoid with one periappendiceal lymph node positive for metastatic carcinoid tumor reportable to SEER? See Discussion.
The patient had an appendectomy followed by a hemicolectomy. No residual carcinoid tumor was identified but there was one lymph node positive for metastatic carcinoid tumor.
Yes, this carcinoid is reportable to SEER. This carcinoid is malignant by virture of the lymph node metastasis. Code the behavior as /3.
EOD-Size of Primary Tumor: Pathologist states that the size of the tumor is difficult to measure but is greater than 3cm but less than 5cm. How would we code the tumor size?
For cases diagnosed 1998-2003:
Code the largest dimension mentioned, since that is the standard rule for coding tumor size. Keep in mind that tumor size is not used in analysis for certain sites such as stomach, colon & rectum, ovary, prostate, and urinary bladder. Tumor size is important for analysis for certain sites such as lung, bone, breast, and kidney.
Other Therapy: How do we classify "thalidomide" when it is given as cancer directed therapy?
Code to the appropriate code (1, 2 or 3) under Other Therapy, depending on whether the drug was given as part of a clinical trial. If not part of a clinical trial, assign code 1 [Other cancer-directed therapy].
Thalidomide is not FDA approved for treating cancer. It is under investigation for anti-angiogenesis effects in different cancers.
Grade, Differentiation--Hematopoietic: Is this field coded to 6 [B-cell] from a flow cytometry that specifies the percentage of B-cells that exist within the percentage of lymphoid cells in the bone marrow biopsy? See Description.
Bone marrow biopsy, Final path diagnosis: consistent with small lymphocytic lymphoma/chronic lymphocytic leukemia. Comment: flow cytometry analysis was performed on bone marrow aspirate. The gated population of lymphoid cells comprises approximately 19% of total nucleated cells. Of these, 53% are B-cells which express CD19, CD22. These findings are consistent with the above diagnosis.
For cases diagnosed prior to 1/1/2010:Yes, assign code 6, B-cell. The flow cytometry analysis confirms B-cell.
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.
Multiple Primaries (Pre-2007)--Thyroid: Would a papillary carcinoma of the right lobe of the thyroid diagnosed approximately 2 1/2 years after a papillary carcinoma of the left lobe be coded as a second primary? See Description.
8/31/1999: papillary carcinoma, left lobe thyroid, treated with lobectomy.
1/17/2002: papillary carcinoma, right lobe, treated with lobectomy, completion thyroidectomy.
For tumors diagnosed prior to 2007:
Yes, this is a second primary. The second papillary carcinoma was more than 2 months after the first and not specified as recurrent or metastatic.
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.
Scope of Regional Lymph Node Surgery 2003+/Number of Regional Lymph Nodes Examined--Hematopoietic/Brain/Lymph Nodes/Ill-defined/Unknown: Are codes 9 [Unknown; not stated] and 99 [Unknown; not stated] used respectively for these data items for the mentioned primary sites?
For cases diagnosed Jan 2003 and later:
The Number of Regional Lymph Nodes Examined field is blank for 2003+ cases.
Histology (Pre-2007)--Colon: What code is used to represent the histology "Adenocarcinoma, intestinal type?" See Description.
The code 8144/3 is not valid for colon primaries. Should we code these as 8140/3 [Adenocarcinoma, NOS] or over-ride the error message?
For tumors diagnosed prior to 2007:
Code adenocarcinoma, intestinal type of the colon 8140 [Adenocarcinoma, NOS]. Do not use code 8144 for intestinal type adenocarcinoma in the colon.
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.
