Question 1: What was the best response by CT (radiographic) criteria to HCT or cellular therapy since the date of the last report?

The intent of questions 1 is to determine the best overall response to HCT or cellular therapy based on radiographic response criteria. If the recipient was already in a radiographic complete remission (CR) at the start of the preparative regimen / infusion report “Continued Complete Remission” for question 1 and go to question 4.

When evaluating the best response, determine the disease status within the reporting period using the radiographic international working group criteria provided in the in LYM Response Criteria section of the Forms Instructions Manual. Compare this response to all previous post-infusion reporting periods. If the response in the current reporting period is the best response to date, report the disease status established within this reporting period. If a better response was established in a previous reporting period, report the previously established disease status. See question 2 to indicate that this disease status was previously reported.

Include response to any post-infusion treatment planned as of Day 0. If post-infusion therapy is given as prophylaxis or maintenance for recipients in CR, consider this “planned therapy,” even if this was not documented prior to the transplant. Also, include response to a treatment for persistent (i.e., minimal residual disease) disease.

Do not include response any treatment for relapse or progression. If a recipient started treatment for relapse or progression report the best response prior to the initiation of treatment (even if this was confirmed in a prior reporting period).

For scenarios where this form is completed for both the cellular therapy track and the HCT track:

Do not report a best response to the HCT on a disease form for the cellular therapy. If recipient has received a cellular therapy then an HCT, and this form is being completed for the first cellular therapy infusion, then the best response achieved will be prior to the start of preparative regimen for the subsequent HCT (or prior to the HCT if no preparative regimen is given).

Do not report a best response to the cellular therapy on a disease form for the HCT. If recipient has received an HCT then a cellular therapy, and this form is being completed for the first HCT infusion, then the best response achieved will be prior to the start of systemic therapy for the subsequent cell therapy (or prior to the CT if no systemic therapy is given).

See best response to infusion reporting scenarios after question 6 below for reporting examples.

Question 2: Was the date of best response previously reported?

If the best response to HCT / cellular therapy was first documented during the current reporting period, report “No” and go to question 3. If the best response was achieved during a previous reporting period (and therefore reported on a previous LYM Post-Infusion Data Form), report “Yes” and go to question 4.

Do not report “Yes” if completing this form for the 100 day reporting period.

Question 3: Date assessed

Report the date the best response to HCT / cellular therapy was established. This should be the earliest date when all radiographic international working group criteria for the response reported in question 1 were met. If the exact date is not known, use the process described for reporting partial or unknown dates in General Instructions, Guidelines for Completing Forms.

Question 4: What was the best response by PET (metabolic) criteria to HCT or cellular therapy since the date of the last report?

The intent of questions 4 is to determine the best overall response to HCT or cellular therapy based on metabolic response criteria. If the recipient was already in a metabolic CR at the start of the preparative regimen / infusion report “Continued Complete Remission” for question 4. If the recipient’s primary disease is a non-PET avid lymphoma, report “Not assessed” for question 4.

When evaluating the best response, determine the disease status within the reporting period using the metabolic international working group criteria provided in the in LYM Response Criteria section of the Forms Instructions Manual. Compare this response to all previous post-infusion reporting periods. If the response in the current reporting period is the best response to date, report the disease status established within this reporting period. If a better response was established in a previous reporting period, report the previously established disease status. See question 5 to indicate that this disease status was previously reported.

Include response to any post-infusion treatment planned as of Day 0. If post-infusion therapy is given as prophylaxis or maintenance for recipients in CR, consider this “planned therapy,” even if this was not documented prior to the transplant. Also, include response to a treatment for persistent disease.

Do not include response any treatment for relapse or progression. If a recipient started treatment for relapse or progression report the best response prior to the initiation of treatment (even if this was confirmed in a prior reporting period).

See best response to infusion reporting scenarios below for reporting examples.

Question 5: Was the date of best response previously reported?

If the best response to HCT / cellular therapy was first documented during the current reporting period, report “No” and go to question 6. If the best response was achieved during a previous reporting period (and therefore reported on a previous LYM Post-Infusion Data Form), report “Yes.”

Do not report “Yes” if completing this form for the 100 day reporting period.

Question 6: Date assessed

Report the date the best response to HCT / cellular therapy was established. This should be the earliest date when all metabolic international working group criteria for the response reported in question 1 were met. If the exact date is not known, use the process described for reporting partial or unknown dates in General Instructions, Guidelines for Completing Forms.

Best Response to Infusion Reporting Scenarios:

A. A recipient in complete metabolic and radiographic remission at the time of infusion has a disease relapse detected on their first PET/CT scan post-HCT.

100 Day Follow-Up Form:
Question 1: Report “Continued complete remission.” This option should be used for all recipients in radiographic CR at the time of infusion regardless of post-infusion disease assessments.
Question 4: Report “Continued complete remission.” This option should be used for all recipients in metabolic CR at the time of infusion regardless of post-infusion disease assessments.

B. A recipient in complete radiographic remission and partial metabolic remission at the time of infusion achieves a complete metabolic remission during the 100 day reporting period (on 6/1/2016). PET/CT studies during the 6 month reporting period continue to show no evidence of disease.

100 Day Follow-Up Form:
Question 1: Report “Continued complete remission.” This option should be used for all recipients in radiographic CR at the time of infusion regardless of post-infusion disease assessments.
Question 4: Report “Complete Remission.” Use this option to indicate a metabolic CR was achieved post-infusion for recipients not in metabolic CR at the time of infusion.
Question 5: Report “No.” The date of best response has not been previously reported. Never report “Yes” for question 5 on the day 100 follow-up form.
Question 6: Report 6/1/2016 as indicated in the scenario.

Six Month Follow-Up Form:

Disease Assessments at Time of Best Response

Only complete questions 7-20 if the date of best response has been reported for questions 3 or 6. Otherwise, skip questions 7-20 and go to question 21.

For reporting purposes, the definition of “at the time of best response” depends on the reporting period. See Disease Assessment Time Windows below. Only consider assessments with samples collected within the time window which corresponds to the follow-up form being completed. If assessments were performed during the reporting period, but the samples were not collected within the indicated time window, consider them “Not done” when completing questions 7-20.

Table 1. Disease Assessment Time Windows

Follow-Up Form Approximate Time Window
100 Day + / – 15 days of date of best response (Question 3 / 6)
6 Month + / – 15 days of date of best response (Question 3 / 6)
Annual + / – 30 days of date of best response (Question 3 / 6 )

If the date of best radiographic response (question 3) and the date of best metabolic response (question 6) are both reported and are not the same, use the earlier of the two dates when determining the approximate time window.

Question 7: Was minimal residual disease (MRD) assessed at the time of best response?

Minimal residual disease assessments include flow cytometry, PCR, and next generation sequencing. If testing was performed by any of these three methods on blood, bone marrow, or any other specimen at time of best response, report “Yes” and go to question 8. If testing by these methods was not done at the time of best response or it is not known whether testing was performed, report “No” or “Unknown” respectively and go to question 21.

Question 8-11: Flow cytometry

Indicate the result of flow cytometry testing performed on blood or bone marrow at the time of best response. If testing was “Positive” or “Negative,” report the sample source in questions 9-10. Also, report the date the sample was collected in question 11. If the date is partially known, use the process for reporting partial or unknown dates as described in the General Instructions, General Guidelines for Completing Forms.

If flow cytometry testing was not done at the last evaluation prior to the start of the preparative regimen, report “Not done” for question 8 and go to question 12.

Question 12-15: PCR

Indicate the result of PCR testing performed at the time of best response. If testing was performed for multiple disease markers and any of the test results were positive, report “Positive” for question 12. If testing was “Positive” or “Negative,” report the sample source in questions 13-14. Also, report the date the sample was collected in question 15. If the date is partially known, use the process for reporting partial or unknown dates as described in the General Instructions, General Guidelines for Completing Forms.

If PCR testing was not done at the last evaluation prior to the start of the preparative regimen, report “Not done” for question 12 and go to question 16.

Question 16-19: Next generation sequencing

Indicate the result of next generation sequencing (NGS, 3rd gen) testing performed at the time of best response. If testing was performed for multiple disease markers and any of the test results were positive, report “Positive” for question 16. If testing was “Positive” or “Negative,” report the sample source in questions 17-18. Also, report the date the sample was collected in question 19. If the date is partially known, use the process for reporting partial or unknown dates as described in the General Instructions, General Guidelines for Completing Forms.

If next generation sequencing testing was not done at the last evaluation prior to the start of the preparative regimen, report “Not done” for question 16 and go to question 20.

Question 20: Was documentation submitted to the CIBMTR?

Indicate if documentation is attached to support the findings reported in questions 7-19. For further instructions on how to attach documents in FormsNet3SM, refer to the Training Guide.
