T-cell large granular lymphocytic leukemia with no cytopenias and no associated symptoms

Not every presentation of T-cell large granular lymphocytic leukemia (T-cell LGLL) requires immediate intervention. A recognised subset of patients presents without cytopenias and without disease-related symptoms — and the appropriate clinical pathway for this group differs accordingly.

Clinical scenario

Around 30% of patients may have asymptomatic LGLL, with no cytopenias or associated symptoms. In these individuals, active surveillance is a recognised management strategy — not all asymptomatic patients require treatment. Identifying this subgroup and managing them appropriately is essential to avoiding unnecessary intervention.

The full structured protocol defines the evidence-based pathway for this specific scenario, including when and how to act.
