Chemotherapy and Unrelated Donor Stem Cell Transplantation for Patients With Cancers of the Blood and Immune System · Source last updated 2019-03-05

Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: MEDIAN
Unit: Cells/µl
Interval / dispersion: Full Range
Time frame: 2 weeks, and 1, 3, 6, 12, and 24 months post transplant

What was measured

Cluster of differentiation 3 (CD3) - cluster of differentiation 56 (CD56) + Natural Killer (NK) cells within the lymphocyte population were determined by flow cytometry. The absolute numbers of cells/µl were calculated from the absolute lymphocyte count.

Analysis population: 2 of 44 patients who completed the AC arm were transplanted after our cutoff for data analysis and are not included. A total of 5 completed participants did not contribute data due to missing samples, and participants who died and were not able to supply samples for the time points indicated.
