If the indication for infusion is due to a combination of diseases or a transformation of one disease to another, it may be necessary to report multiple disease classifications. The tables below list how common examples of disease combinations and transformations should be reported using the Disease Classification questions.
Table 1. Common Disease Combinations
| Disease Combinations | Report Primary Disease as: | Report disease diagnosis date of: | Complete multiple disease sections of the Disease Classification Form? |
|---|---|---|---|
| FAN or SAA and AML | AML | AML | No |
| FAN or SAA and MDS | MDS | MDS | No |
| MYE and AMY | MYE | MYE | No |
Table 2. Common Disease Transformations
| Disease Transformation | Report primary disease as: | Report disease diagnosis date of: | Complete multiple disease sections of the Disease Classification Form? |
|---|---|---|---|
| MDS or MPN to AML | AML | AML | Yes – AML and MDS or MPN |
| JMML to AML | AML | AML | Yes – AML and MDS (select questions only) |
| CLL to NHL (i.e., Richter’s Syndrome) | NHL | NHL | No |
AML=Acute Myelogenous Leukemia; AMY=Amyloidosis; CLL=Chronic Lymphocytic Leukemia; FAN=Fanconi Anemia; MDS=Myelodysplastic Syndrome; MPS=Myeloproliferative Disease; MYE=Multiple Myeloma; NHL=Non-Hodgkin Lymphoma; SAA=Severe Aplastic Anemia.
Question 1: Date of diagnosis for primary disease for HCT / cellular therapy
The date of diagnosis is important because the interval between diagnosis and infusion is often a significant indicator for the recipient’s prognosis post-infusion. Refer to the disease-specific section of the Disease Classification (2402) manual for guidelines when reporting the diagnosis date for each disease.
Use the following guidelines if the recipient was diagnosed with a non-malignant disease:
- Newborn screening: If the diagnosis was made using a newborn screening, report the date of birth as the diagnosis date.
- Genetic testing: If the recipient was not diagnosed with a newborn screening, report the date of genetic testing that confirmed the diagnosis.
- Other definitive assessment: If genetic testing was not completed, report the date of the other definitive assessment (i.e., electrophoresis, flow cytometry, etc.), that confirmed the diagnosis.
- Diagnosis by exclusion: If the diagnosis was made by exclusion (i.e., all assessments returned normal and the diagnosis made clinically), report the date of the clinical diagnosis as documented by the physician.
- Diagnosis at an outside center: If the diagnosis was completed at an outside center (the confirmatory test such as newborn screening, genetic testing, another definitive test, or clinical diagnosis) and the HCT / CT center performs their own confirmatory testing, report the date of the initial confirmatory test as the diagnosis date.
- If the exact date is not known or documentation is limited, report an estimated date.
If this is a subsequent infusion for the same disease, report the date of diagnosis as the first date when the primary disease for infusion was diagnosed.
If this is a subsequent infusion for a new malignancy (or other new indication), report the date of diagnosis of the new malignancy.
If the exact diagnosis date is not known, use the process described in General Instructions, Guidelines for Completing Forms.
Question 2: What was the primary disease for which the infusion was performed?
Select the primary disease for which the recipient is receiving the infusion and continue with the appropriate disease classification questions. If documentation is unclear, seek clinician clarification.
