Based on the information provided, code the tumor size as 035.  We asked an expert pathologist to review this question and she said to use the larger measurement.  She also said "the pathologist usually cuts the anus and rectum open like a tube; the “circumference” would be measured flat."

For tumors diagnosed prior to 2007:

Code the Histology field to 8500/3 [ductal carcinoma] unless the combination is ductal and lobular.

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.

Code the Radiation field to 2 [Radioactive implants]. Codes for radiation are based on HOW the radiation is delivered, rather than the particular type of radioactive material used.

Radioactive eye-plaques contain rice-sized iodine-125 or palladium-103 seeds which emit low energy photons. They are sewn or glued into the eye. The plaque remains for 5 to 7 days and is then removed.

For tumors diagnosed prior to 2007:

Code the Histology field for the first example to 8140/2 [Adenocarcinoma, NOS, in situ] and for the second example to 8077/2 [AIN, grade III]. For both of the cases code the Grade, Differentiation field to 9 [Cell type not determined not stated or not applicable]. The 6th digit (grade code) of ICD-O-3 describes how much or how little a malignant tumor resembles the normal tissue from which it arose. In contrast, "grade" is used in the examples above to describe the degree of dysplasia, from mild dysplasia (low grade) to severe dysplasia (high grade). Do not record the degree of dysplasia in the 6th digit grade field.

For tumors diagnosed 2007 or later, refer to the MP/H rules for histology coding instructions. 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.

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.

Assign 8523/3.

The 2013 revision to ICD-O-3 has a new code for mixed acinar ductal carcinoma; however, this new code will not be implemented in the U.S. until 2018 or later. Page 7 of the Guidelines for ICD-O-3 Update Implementation document released by NAACCR 1/1/2014 instructs us to use 8523/3 in the meantime.

Assign code 51 or 52 if a patient has an excisional biopsy and axillary dissection followed by a simple mastectomy during the first course of therapy. Code the cumulative result of the surgeries, which is a modified radical mastectomy in this case.

SEER collects only one surgery code per case. Code the most invasive, extensive or definitive surgery in Surgery of Primary Site.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

This case should be accessioned as a single primary lymphoma of bilateral orbits per Rule M2. Abstract a single primary when there is a single histology. Both orbits showed the same histology. Note 1 for Rule M2 states bilateral involvement of lymph nodes and/or organs is a single primary.

For cases diagnosed 2007 or later:

No. When the invasive component is discovered as part of the work-up phase leading to treatment decisions, the case should not be abstracted as a multiple primary. In the rare instance when a patient has not been treated and is still having diagnostic work-up greater than 60 days after the malignancy is diagnosed, do not count the invasive diagnosis as a new primary.

For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

This case should be accessioned as a single primary, acute myeloid leukemia [9861/3].

MDS diagnosed prior to 1/1/2001 is not a reportable disease process. However, because MDS is currently a reportable disease process, it must be considered when trying to determine whether the AML represents a separate primary.

• If the Heme DB indicates MDS and AML represent different (separate) disease processes, only one primary is reported (i.e., AML) because the 1999 diagnosed MDS is not reportable.

• If the Heme DB indicates MDS and AML represent the same disease process, then no primaries are reported because MDS was not reportable in 1999.

Rule M2 does not apply to this case because more than one histology is mentioned in the scenario. According to the Heme DB, MDS can transform to AML. Rules M8-M13 apply to cases involving transformation. In this case, Rule M10 applies because the patient was diagnosed with a chronic neoplasm (myelodysplastic syndrome) followed greater than 21 days later by an acute neoplasm (AML).
