EOD-Pathologic Extension--Prostate/Lymphoma: How is this field coded for a prostatic lymphoma?
For cases diagnosed 1998-2003: Do not code the prostate pathologic extent of disease field for prostatic lymphoma. Leave the path extension for prostate field blank. Code the extent of disease using the lymphoma scheme. Use ONLY the lymphoma scheme - do NOT try to code both lymphoma and prostate extension fields for prostatic lymphoma.
EOD-Size of Primary Tumor/First Course Treatment--Breast: How is tumor size coded when preventative tamoxifen treatment precedes breast cancer diagnosis? Can we code the tumor size from the surgical specimen? Is tamoxifen treatment here? See Description.
What is the tumor size in this situation? Patient is on the STAR trial (preventative tamoxifen for women with high risk for breast cancer). Patient develops breast cancer and has surgery.
For cases diagnosed 1998-2003: Code EOD-Size of Primary Tumor from the surgical pathology report.
Do not code this preventative tamoxifen as first course cancer-directed treatment. This tamoxifen was part of a clinical trial intending to delay or prevent beast cancer from developing.
Primary Site/Histology (Pre-2007)--Bone: How are these fields coded for a squamous cell carcinoma in bone? See Description.
The consult path report says "I believe that there is definitely high grade malignant tumor in this amputation specimen, and that this tumor represents an invasive squamous cell carcinoma, which is extending into the bone and permeating in between the bone trabeculae. ... The fact that squamous cell carcinoma can arise from the sinuses of chronic osteomyelitis is well recognized."
For tumors diagnosed prior to 2007:
Based on the information provided, code the primary site as C40._ or C41._ [bone] because the tumor originated in the sinuses of chronic osteomyelitis. Code to the site in which the tumor arises. Override the SEER site/histology edits to allow this rare combination of bone and squamous cell carcinoma.
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.
First-Course of Cancer-Directed Therapy Fields/Hematopoietic, NOS: How do you code treatment for a myelodysplastic syndrome when a patient is admitted to receive a "second transfusion 7 months after diagnosis"?
The first course of treatment for these hematopoietic primaries lasts until there is a treatment change. For the case you cite the second transfusion (7 months after diagnosis) would be first course treatment. Code the Other Cancer-Directed Therapy Field to 1 [Other cancer-directed therapy].
EOD-Extension--Lymphoma/Brain and CNS: How is this field coded for a primary brain lymphoma that is described as multi-focal?
For cases diagnosed 1998-2003: Since brain is the only site involved in this example, assign code 11 [Localized involvement of a single extralymphatic organ or site].
EOD-Clinical Extension--Prostate: Must all three criteria be met (an elevated PSA; documentation that the physical exam was negative; and, if a TRUS was done, there is documentation that the findings were negative) in order to code this field to 15 [Tumor identified by needle by elevated PSA]?
For cases diagnosed 1998-2003:
Refer to the Prostate EOD Coding Guidelines, Final version distributed to SEER Registries 6/20/2001.
Prostate clinical EOD extension code 15 is used when all three criteria are met as listed on page 3 of the Prostate EOD Coding Guidelines. Meeting 1 or 2 of the 3 criteria is not sufficient for code 15. PE must be done and documented as negative. TRUS may or may not be done, but if done, must be documented as negative. PSA must either be elevated or there is no documentation about the PSA.
Codes 20 and 23-24 would be used with positive physical exam or positive TRUS.
Use codes 30-34 when there is no documentation that the physical exam was negative, or no documentation that the TRUS was negative, or when the prostatic apex is involved.
Primary Site/Histology (Pre-2007): What are the correct site and histology codes for "tubal serous adenocarcinoma" identified in a fallopian tube? See Description.
The pathology report of a laparoscopic left salpingo-oophorectomy states: 1.5 cm intraluminal mass left fallopian tube: micro: tubal serous adenocarcinoma, poorly differentiated, infiltrates the muscular wall of the fallopian tube; serosa does not appear to be penetrated. The left ovary is negative for malignancy.
For tumors diagnosed prior to 2007:
Code histology as 8441 [serous adenocarcinoma].
The primary site for this case is fallopian tube, not the suggested site code of ovary.
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 (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.
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.
