Another study on adult T-cell leukemia/lymphoma (ATLL) focused on the expression of FoxP3 in the malignant cell population and reported that patients with FoxP3-negative tumors showed a tendency toward better survival in comparison with those with strong or intermediate intratumoral expression of FoxP3 (19). The gene discussed is FOXP3; the disease is adult T-cell leukemia/lymphoma.
