Patients with adult T-Cell leukemia/lymphoma (ATL) have a poor prognosis and are prone to infectious complications, especially in the acute subtype. Treatment options include high doses of zidovudine and interferon alfa or chemotherapy, but the infection rate is high. Invasive fungal infections significantly impact survival rates, particularly in acute subtype patients exposed to drug therapy.
Patients treated for adult T-Cell leukemia/lymphoma (ATL) have a poor prognosis and are prone to infectious complications which are poorly described. As the French reference center for ATL, we retrospectively analyzed 47 consecutive ATL (acute, n = 23; lymphoma, n = 14; chronic, n = 8; smoldering, n = 2) patients between 2006 and 2016 (median age 51 years, 96% Afro-Caribbean origin). The 3-year overall survival (OS) was 15.8%, 11.3%, and 85.7% for acute, lymphoma, and indolent (chronic and smoldering) forms respectively. Among aggressive subtypes, 20 patients received, as frontline therapy, high dose of zidovudine and interferon alfa (AZT-IFN alpha) resulting in an overall response rate (ORR) of 39% (complete response [CR] 33%) and 17 chemotherapy resulting of an ORR of 59% (CR 50%). Ninety-five infections occurred in 38 patients, most of whom had an acute subtype (n = 73/95; 77%). During their follow-up, patients receiving frontline chemotherapy or frontline AZT-IFN alpha developed infections in 74% (n = 14/19) and 89% (n = 24/27) of the cases respectively. Sixty-four (67%) of infections were microbiologically documented. Among them, invasive fungal infections (IFI, n = 11) included 2 Pneumocystis jirovecii pneumonia, 5 invasive aspergillosis, and 4 yeast fungemia. IFI exclusively occurred in patients with acute subtype mostly exposed to AZT-IFN alpha (n = 10/11) and experiencing prolonged (> 10 days) grade 4 neutropenia. Patients with aggressive subtype experiencing IFI had a lower OS than those who did not (median OS 5.4 months versus 18.4 months, p = 0.0048). ATL patients have a poor prognosis even in the modern era. Moreover, the high rate of infections impacts their management especially those exposed to AZT-IFN alpha.
