Prognostic impact of morphological lymphocyte counts on aggressive adult T-cell leukemia/lymphoma: Japan ATL nationwide registry analysis
Routine blood counts independently predict survival in aggressive T-cell lymphoma at zero additional cost, immediately applicable to current clinical practice.
A nationwide prospective Japanese registry of 638 aggressive ATL patients identifies that routine CBC lymphocyte counts — both the normal (host immunity marker) and abnormal (tumor burden) fractions — independently predict survival outcomes, adding clinically useful information to established prognostic scores at essentially zero additional cost. The finding is immediately applicable since morphological lymphocyte counts are universally available.

Why it surfaced
Strong prospective nationwide registry design (n=638, 152 institutions) validates readily available CBC parameter as independent prognostic factor in a rare lymphoma; near-term implementable given zero additional testing cost.
