Answer:
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Accession two primaries per Rule M15 which instructs you to use the Multiple Primaries Calculator to determine the number of reportable primaries. The result is that mycosis fungoides [9700/3] and peripheral T-cell lymphoma [9702/3] represents two primaries.
SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.
History:
This SINQ question has been updated to the Hematopoietic & Lymphoid Neoplasm Manual & Database published January 2014.
The original answer below was written based on the rules in 2010
The previous diagnosis was mycosis fungoides [9700/3]. For cases diagnosed 2010-2011, go to the 2010 Hematopoietic Database and enter 9700/3 in the search mechanism. Click on the Display button and scroll down to the Transformations section. It tells you that MF transforms to large T-cell lymphoma.
Use the 2010 Heme DB to find a provisional ICD-O-3 code for the May 2010 diagnosis. Do a smart search by entering "large cell" into the search mechanism. (These are words mentioned in both the transformation information and the May diagnosis).
Click on the "Matched Term" label in the grid header above the displayed results. The terms are now alphabetized. Scroll down until you find an appropriate diagnosis. (Look at the alternate names for each of these entries.) You will come to anaplastic large cell lymphoma [9714/3]. One of the alternate names is anaplastic large cell lymphoma CD30+. This fits the May diagnosis.
To display the detailed information on this disease, double click on the disease name in the grid. Click on the Display Abstractor Notes button. Always use the Abstractor Notes when you are unsure of a site/histology match. The Abstractor Notes for this disease state one of the most commonly involved extranodal sites is skin.
Check the reportability instructions in the Heme Manual: the new ICD-O-3 code is included in the reportability range.
Go through to the multiple primary rules. M13 applies and instructs you to go to the multiple primaries calculator in the 2010 Heme DB.
Enter both histologies 9700/3 and 9714/3 into the MP calculator. The result is "New Primary."
Create an abstract for the anaplastic large cell lymphoma [9714/3]. If the lymph nodes were biopsied because there was a skin lesion or lesions in that region, code the primary site to skin, NOS. If the lymph nodes were randomly biopsied or if the physician noted adenopathy without any skin lesion in that area, code the primary site to lymph nodes (appropriate region).
The answers for SINQ questions with 2010 ID numbers were written using the 2010 Heme & Lymph Manual & DB. The instructions for using the 2010 Hematopoietic Database were written for the version of the software in use as of 5/24/2011. The user interface of the web-based 2010 Hematopoietic Database available from the SEER website varies slightly from the 5/24/2011 version in that the web-based version provides all the disease information in one scrollable window.
For cases diagnosed 2010-2011, access the 2010 Hematopoietic Database at http://seer.cancer.gov/tools/heme/. Click on Hematopoietic Project. Click on Hematopoietic and Lymphoid Database. For 2010-2011 diagnoses, click on the "use the 2010 database" label in the upper right corner of the screen. The 2010 Hematopoietic Coding Manual (PDF) button will appear to indicate the correct version of the program is available now for query.
