Best response is based on response to the HCT and does NOT include response to therapy given for disease relapse or progression post-HCT.

  • If the HCT or cellular therapy was planned as part of initial therapy for a recipient with no disease progression or relapse at any time prior to HCT or cellular therapy, determine the best response by comparing to the disease assessment at the time of initial diagnosis.
  • If the HCT or cellular therapy was performed later in the disease course for a patient who has not received any chemotherapy within 6 months of HCT or cellular therapy or has untreated relapse or progression, determine the best response to HCT or cellular therapy by comparing the disease status immediately prior to the start of the preparative regimen.
  • If the patient had a disease progression or relapse of disease at any time prior to HCT or cellular therapy and was treated to reduce the myeloma burden prior to the start of the preparative regimen, determine the best response to HCT or cellular therapy by comparing to the disease evaluation at the time of relapse or progression. In other words, the baseline is reset to the time of relapse or progression.
  • This comparison is meant to capture the best disease status in response to HCT or cellular therapy that occurred in the reporting interval, even if a subsequent disease relapse or progression occurred during the same reporting interval. If a recipient already achieved their best response in a previous reporting interval, confirm the best response and indicate that the date was previously reported (question 4).

Question 3: For all recipients with primary disease multiple myeloma / plasma cell disorder (PCD) classifications, excluding Amyloidosis, compared to the disease status prior to the preparative regimen, what was the best hematologic response to HCT or cellular therapy since the date of last report? (Include response to any therapy given for post-HCT or post-cellular therapy maintenance or consolidation, but exclude any therapy given for relapsed, persistent, or progressive disease)

The intent of this question is to determine the best overall response to HCT or cellular therapy, which could include any response to planned therapy post-HCT or cellular therapy, or to therapy given for maintenance or prophylaxis. (DO NOT include any response to treatment given for relapsed or progressive disease.) This is assessed in each reporting period. When evaluating the best response, determine the disease status within the reporting period and compare it to all previous post-HCT or post-cellular therapy 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 4 to indicate that this disease status was previously reported.

See the Multiple Myeloma Response Criteria section for multiple myeloma and solitary plasmacytoma disease status definitions. See Plasma Cell Leukemia Response Criteria for plasma cell leukemia disease status definitions.

This question will not be enabled if the primary disease for transplant is monoclonal gammopathy of renal significance (MGRS).

If the recipient was already in CR at the start of the preparative regimen, select Continued complete response (CCR), and continue with question 4.

Example 1: A myeloma patient is transplanted in PR. In the 100-day reporting period all the CR criteria (3% plasma cells in the bone marrow, SPEP/UPEP negative) are met with the exception of a positive immunofixation on serum and urine (two disease assessments were performed in the reporting period indicating a positive immunofixation); in this case VGPR should be reported as the best response to transplant.

Example 2: A recipient with myeloma goes to transplant having established a PR prior to transplant, achieves a VGPR during the first 100 days, and then progresses during the six-month reporting period. The best response to transplant should be reported as “VGPR” on all subsequent forms. See below:

Reporting Period Current Disease Status Q1. Best Response Q5. Date Assessed
Pre-transplant PR —- —-
100-Days Post-HCT VGPR VGPR [date of 1st confirmatory labs]
6-Months Post-HCT Progression VGPR Previously Reported
1-Year Post-HCT PR VGPR Previously Reported

Example 3: A recipient with myeloma goes to transplant having established a CR prior to transplant, maintains the response after transplant, and then relapses within the six-month reporting period. The best response to transplant would be reported as “CCR” for all subsequent reporting periods. See below:

Reporting Period Current Disease Status Q1. Best Response Q5. Date Assessed
Pre-transplant CR —- —-
100-Days Post-HCT CR CCR [date of labs that first confirmed a continued CR]
6-Months Post-HCT Relapsed CCR Previously Reported
1-Year Post-HCT VGPR CCR Previously Reported

Example 4: A recipient with myeloma goes to transplant having established a PR prior to transplant and maintains the response throughout the 100-day reporting period. During the six-month reporting period, the recipient progresses and begins unplanned therapy to treat the worsening disease. During the one-year reporting period, the recipient achieves VGPR. The best response to transplant occurred during the 100-day reporting period because response to unplanned therapy is not captured using this set of questions. See below:

Reporting Period Current Disease Status Q1. Best Response Q5. Date Assessed
Pre-transplant PR —- —-
100-Days Post-HCT PR PR [date of latest labs that confirmed a continued PR]
6-Months Post-HCT Progression PR Previously Reported
1-Year Post-HCT VGPR PR Previously Reported

Example 5: A recipient with myeloma goes into transplant having established VGPR prior to transplant and maintains the response throughout the 100-day reporting period. During the six-month reporting period, the recipient achieves a CR and is placed on maintenance therapy. During the one-year reporting period the recipient maintains the CR. The best response to transplant occurred in the six-month reporting period. See below:

Reporting Period Current Disease Status Q1. Best Response Q5. Date Assessed
Pre-transplant VGPR —- —-
100-Days Post-HCT VGPR VGPR [date of latest labs that confirmed a continued VGPR]
6-Months Post-HCT CR CR date of labs that first confirmed CR
1-Year Post-HCT CR CR Previously Reported

Question 4: Was the date of best response previously reported?

Indicate if the best response was reported on a previous post-HCT plasma cell disorder form (Form 2116). If Yes, and the recipient has a preceding / concurrent diagnosis of amyloidosis (question 2) continue with question 6. If not, continue with question 142.

If the best response achieved during the 100-day reporting period is the same as the pre-transplant disease status, select No, report the latest disease assessment that confirmed the ongoing disease status post-HCT in question 5. For all subsequent reporting periods, report Yes, until a better disease response is achieved.

If the recipient’s pre-transplant disease status was Continued complete response (CCR), select No, report the date of the first assessment that confirmed the ongoing CR in question 5 on the 100-day form. For all subsequent reporting periods, report Yes.

Question 5: Date assessed

Enter the date the best response first began. Report the date of the first assessment, not the date of the second confirmatory assessment. Report the date the blood/urine was collected for the laboratory evaluations (e.g., SPEP/UPEP, serum/urine immunofixation) or report the date the bone marrow was collected for pathologic examination.

If the recipient has a preceding / concurrent diagnosis of amyloidosis (question 2) continue with question 6. If not, continue with question 9.

Example 1: A recipient with myeloma goes into transplant having established a PR prior to transplant. During the 100-day reporting period, the recipient achieves a VGPR. However, the second disease assessment to confirm the VGPR was not performed until one month later (which is in the next reporting period). Those results are available at the time the Day 100 disease form is being completed. The best response to transplant would be reported as “VGPR” with the date it first began in the 100-day reporting period. The recipient maintains the VGPR in the six-month reporting period. The best response to transplant would be reported as “VGPR” with the date as “previously reported” in the six-month reporting period.

Example 2: A recipient with myeloma goes into transplant having established a PR prior to transplant. During the 100-day reporting period, the recipient achieves a VGPR. However, a second disease assessment to confirm the VGPR response is not available when the form is being completed. The best response to transplant would be reported as “PR” with the date of the latest disease assessment.

Example 3: A recipient with myeloma goes into transplant having established a PR prior to transplant. During the 100-day reporting period, the recipient achieves a VGPR. However, a second disease assessment to confirm the VGPR response is not available when the form is being completed. The best response to transplant would be reported as “PR” with the date of the latest disease assessment in the 100-day reporting period. When completing the six-month form, a second disease assessment to confirm a VGPR response is available. The best response to transplant would be reported as “VGPR.” However, since the VGPR first began during the Day 100 reporting period, an error correction needs to be completed to update the disease status and date first achieved on the Day 100 report.

Question 6: For recipients with primary disease or concurrent / history of Amyloidosis, compared to the disease status prior to the preparative regimen, what was the best hematologic response to HCT or cellular therapy since the date of last report? (Include response to any therapy given for post-HCT or post-cellular therapy maintenance or consolidation, but exclude any therapy given for relapsed, persistent, or progressive disease):

The intent of this question is to determine the best overall response to HCT or cellular therapy, which could include any response to planned therapy post-HCT or post-cellular therapy, or to therapy given for maintenance or prophylaxis. (DO NOT include any response to treatment given for relapsed or progressive disease.) This is assessed in each reporting period. When evaluating the best response, determine the disease status within the reporting period and compare it to all previous post-HCT or post-cellular therapy 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 7 to indicate that this disease status was previously reported.

See the Amyloidosis Response Criteria section for disease status definitions.

If the recipient was already in CR at the start of the preparative regimen, select Continued complete response (CCR), and continue with question 7.

Question 7: Was the date of best response previously reported?

Indicate Yes or No if the best response was reported on a previous post-HCT plasma cell disorder form (Form 2116). If Yes, continue with question 54.

If the best response achieved during the 100-day reporting period is the same as the pre-transplant disease status, select No, report the latest disease assessment that confirmed the ongoing disease status post-HCT in question 8. For all subsequent reporting periods, report Yes until a better disease response is achieved.

If the recipient’s pre-transplant disease status was Continued complete response (CCR), select No, report the date of the first assessment that confirmed the ongoing CR post-HCT in question 8 on the 100-day form. For all subsequent reporting periods, report Yes.

Question 8: Date assessed

Enter the date the best response first began and continue with question 9. Report the date of the first assessment, not the date of the second confirmatory assessment. Report the date the blood/urine was collected for the laboratory evaluations (e.g., SPEP/UPEP, serum/urine immunofixation) or report the date the bone marrow was collected for pathologic examination.

Laboratory Assessments at the Time of Best Response

Questions 9-33 refer to disease assessments performed at the time of best response for their primary disease for infusion (question 5 or 8). Report testing performed closest to the date of best response and within the time windows in the Disease Assessment Time Windows table.

Disease Assessment Time Windows

Follow-Up Form Approximate Range
100 Day +/- 15 days of date of best response (question 5 or 8)
6 Month +/- 15 days of date of best response (question 5 or 8)
Annual +/- 30 days of date of best response (question 5 or 8)

Indicate if the results of urinary immunofixation at the time of best response are Known or Unknown. If Unknown or Not applicable, continue with question 28. Report Not applicable for recipients with non-secretory myeloma.

Question 26: Original monoclonal bands

Indicate Yes if the original monoclonal band was present or No if it was not present.

Question 27: New monoclonal (or oligoclonal) bands

Indicate Yes if a new monoclonal (or oligoclonal) band was present or No if it was not present.

Questions 28 – 29: Total urine protein in 24 hours

Questions 32 – 33: Urine protein / creatinine ratio

Indicate whether the urinary protein / creatinine ratio was Known or Unknown at the time of best response. The value reported here should be based on a 24-hour urine collection. If Known, report the laboratory value and unit of measure documented on the laboratory report. If Unknown, continue with question 34. This question is only required if the primary disease (question 1) is MGRS or Amyloidosis or if there is evidence / history of (question 2) MGRS or Amyloidosis.

Question 34: Was minimal residual disease (MRD) assessed post-HCT / CT or post-infusion evaluation? (report only bone marrow or blood results)

Minimal residual disease (MRD), is an indicator of increased risk for disease relapse and / or progression. MRD can be assessed by different methods including, but not limited to, next generation sequencing (NGS), Sanger sequencing, polymerase chain reaction (PCR) testing, chromosomal / genomic microarray analysis, fluorescence in situ hybridization (FISH), karyotyping, or flow cytometry.

Indicate if MRD was performed by next generation sequencing (NGS) or next generation flow (NGF) at the time of best response.

If any MRD testing was performed for patients with myeloma, answer this question as Yes. If no MRD testing methods were performed or it was not known if performed, report No or Unknown and continue with question 43.

Questions 35 – 36: Next generation sequencing (NGS)

Indicate whether the MRD result at the time of best response is Positive, Negative, or Not done by NGS testing. If Positive, report the sample source (Blood or Bone marrow). If Negative or Not done, continue with question 39.

Questions 37 – 38: Indicate the sensitivity of the next generation sequencing (NGS) testing

Indicate the testing sensitivity of the NGS testing performed at the time of best response. If the specificity is not listed in this section, report Other and specify the sensitivity as documented on the laboratory report in question 38.

Questions 39 – 40: Next generation flow (NGF)

Indicate whether the MRD result at the time of best response is Positive, Negative, or Not done by NGF testing.

  • If Positive, report the sample source (Blood or Bone marrow)
  • If Negative, report the sample source (Blood or Bone marrow)
  • If Not done, continue with question 43

Questions 41 – 42: Indicate the sensitivity of the next generation flow (NGF) testing

Indicate the testing sensitivity of the NGF testing performed at the time of best response.

NGF testing is used to identify minimal residual disease (MRD) in patients with multiple myeloma. Some NGF reports include a “level of detection” rather than a “level of sensitivity.” In these cases, the “level of sensitivity” can be derived from the level of detection. Please refer to the report and example below for further instruction.

Example:

  • Level of Detection: 0.001 is equal to:
  • Level of Sensitivity: 10 -5 (1/100,000 cells) and should be reported in question 41)

If the specificity is not listed in this section, report Other and specify the sensitivity as documented on the laboratory report.

Questions 43 – 44: Plasma cells in bone marrow aspirate by flow cytometry

Indicate whether the percentage of plasma cells in the bone marrow aspirate assessed by flow cytometry at the time of best response is Known or Unknown. If Known, report the percentage of plasma cells in the bone marrow aspirate documented on the pathology report. If Unknown, continue with question 45.

Questions 45 – 46: Plasma cells in bone marrow aspirate by morphologic assessment

Indicate whether the percentage of plasma cells in the bone marrow aspirate was Known or Unknown by morphologic assessment at the time of best response.
