3. Comparison of quantitative NPM-ALK PCR results between bone marrow and peripheral blood.
Comparison of quantitative NPM-ALK PCR results between bone marrow and peripheral blood. Number of NPM-ALK copies/104 copies ABL in bone marrow and peripheral blood of 19 patients with a positive RT-PCR in bone marrow and blood.

5. Quantitative NPM-ALK PCR results in bone marrow according to the outcome of the ALCL patients.
Quantitative NPM-ALK PCR results in bone marrow according to the outcome of the ALCL patients. Normalized NPM-ALK copy numbers (copies NPM-ALK/104 copies ABL) in bone marrow of the 74 patients with either a negative qualitative BM PCR (= 0 copies NPM-ALK) or a positive qualitative BM PCR using quantitative PCR results. TRM indicates treatment related mortality; sec mal, second malignancy.

6. Outcome of ALCL patients according to quantitative PCR results for NPM-ALK in bone marrow.
Outcome of ALCL patients according to quantitative PCR results for NPM-ALK in bone marrow. (A) Cumulative incidence of relapse and Kaplan-Meier estimates of (B) event-free survival and (C) overall survival of the 74 patients with either a negative qualitative BM PCR or a positive qualitative BM PCR using quantitative PCR results and a NPM-ALK cutoff copy number of 10/104 copies ABL (NCN).
