For cases diagnosed 2021 or later, VIN II-III is reportable. Similarly, AIN II-III, VAIN II-III, etc. are reportable. For cases diagnosed 2021 or later, the primary resource for reportability is ICD-O-3.2. Squamous intraepithelial neoplasia, grade II is listed in ICD-O-3.2 as 8077/2 making it reportable. This applies to the various sites of intraepithelial neoplasia grade II including anus, vulva, and vagina.

Epithelioid angiomyolipoma (AML) [8860/0] of the kidney is not reportable unless stated to be malignant.

If the pathologist confirms this is a malignancy, apply ICD-O-3 Rule F (Matrix principle) and assign the behavior code /3. If confirmation is received, accession the case using the morphology code 8860/3 [malignant angiomyolipoma].

Abstract a single primary per Rule M2; a single histology is a single primary diagnosed. The histology code for both the 2001 and 2011 diagnoses is 9680/3[diffuse large B-cell lymphoma]. Case is coded as diagnosed in 2001.

The hematopoietic physician experts say that the issue with lymphomas is that the patient may be disease-free then recur years later. Even though years have passed, this is still a recurrence or relapse. Currently, there are no molecular markers that are able to distinguish "new primaries" from recurrences. There are also no established criteria for timing rules that could be used to determine a new primary from a recurrence.

There is no time limit set to update histology to a more specific disease process if a patient has an initial NOS histology identified. Unlike solid tumors, hematopoietic and lymphoid neoplasms may take a year or more to manifest the specific disease. This is simply a part of the "disease characteristics."

Abstract a single primary per M2, a single histology represents a single primary. Code the histology to 9983/3 [MDS/RAEB-2.]

The Heme DB guidelines were interpreted correctly. MDS/RAEB can transform to AML and would be two separate primaries there had also been a reportable diagnosis of AML. The 7/2/2010 peripheral blood showed MDS and a clonal abnormality that was "compatible with MDS/AML." The 10/7/2010 bone marrow biopsy showed only RAEB-2 with "evolution towards AML with myelodysplasia related changes." Ambiguous terminology is only used to help determine reportability; it not used to code a more specific histology. In this case, there was only ambiguous terminology used to describe the AML.

It is important to understand the implication of incorrectly assigning histology codes for hematopoietic and lymphoid neoplasm using ambiguous terminology. Using this case as an example, the patient was not treated until three months after the 7/2/2010 peripheral blood diagnosis of MDS compatible with MDS/AML. The medical literature indicates that AML, if left untreated, is usually fatal within 1-3 months. The treatment given 10/6/2010, 3 months after the "compatible with" diagnosis, was a drug used to treat MDS and not AML.

The other issue with this case is that the bone marrow examination, which is more reliable than peripheral blood, showed only "evolution towards AML." This means that the bone marrow is exhibiting the changes seen in the final stages of MDS prior to progression to AML. Wait for a definitive diagnosis of AML and/or treatment for AML before abstracting the second primary.

Per Rule 18, code the primary site to C775 [pelvic lymph nodes]. Per Rule PH18, code the primary site to the specified lymph node region when the site of lymphoma is described only as a mass. This rule also indicates that the Code pelvic lymph nodes [C775] when the lymph nodes are described as a pelvic mass.

This rule has been effect for SEER for over 20 years. It is based on the fact that a number of lymphomas that originate in nodes are not diagnosed until those nodes become matted or fixed. The presentation is then one of a "mass" in those nodal regions.

For cases diagnosed 2021 and later

VIN II-III is reportable based on ICD-O-3.2 which lists squamous intraepithelial neoplasia, grade II as 8077/2 making it reportable. Also see SINQ 20120094.

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

Hemophagocytic syndrome, also known as hemophagocytic lymphohistiocytosis (HLH), is not reportable. Per Appendix F, HLH is caused by an over stimulated immune system (infection, etc.). It is a clinical syndrome associated with a variety of underlying conditions. To be reportable, a child's diagnosis must state "fulminant hemophagocytic syndrome" to be reportable (9724/3). This is not the situation in this case.

"Hemophagocytic lymphohistiocytosis" is also listed in Appendix F: Non-Reportable List for Hematopoietic Diseases.

Abstract two primaries for this scenario per Rule M7. The first primary is the renal pelvis in Oct. 2006; the second primary is the ureter in Nov. 2009. The bladder tumor in July 2008 is not a new primary per Rule M8.

Compare the diagnosis date of the current (most recent) tumor to the diagnosis date of the original tumor. This applies even if the patient had six occurrences in-between these dates; you still compare the current tumor to the diagnosis date of the original tumor and ignore recurrences in this process.

For cases diagnosed 2007 or later, code the histology as papillary carcinoma, poorly differentiated [8260/33].

The WHO classification lists grade III papillary carcinoma as one of the synonyms for poorly differentiated thyroid carcinoma.

The steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Other Sites Histo rules because site specific rules have not been developed for this primary.

Start with the SINGLE TUMOR: INVASIVE ONLY module, rule H8. The rules are intended to be reviewed in consecutive order within a module. Per rule H13 "phenotype" is not a term used to code a more specific histology. Moving to Rule H14 the histology is coded 8260/3 [papillary adenocarcinoma].

Arimidex has not been approved to treat endometrial cancer. It is not prescribed for pre-menopausal women. Clarify with the physician why the drug was being used. If the physician states Arimidex was given to reduce tumor burden, code as hormone therapy.
