Differences in the number of lymphoma cells, as measured by our QC-PCR assay, for each clinical parameter were analyzed with Mann-Whitney U Test. Two-tailed P values were corrected for ties. Statistically significant differences (P < .05) are represented in bold.
All patients in first remission failed to achieve a complete remission after completing the initial chemotherapy.
Identified on pathologic examination.
