Prognostic impact of organ involvement in aggressive adult T-cell leukemia/lymphoma: definition of risk organ and proposal of a prognostic index
To explore the impact of organ involvement on prognosis in aggressive adult T-cell leukemia/lymphoma (ATL) and to propose a prognostic index based on organ involvement, focusing on specific prognostic factors.
Key Findings:
78% of patients had peripheral blood involvement, 67% bone marrow, 90% lymph nodes, and significant involvement in other organs, highlighting the prevalence of organ involvement.
CNS, lung, and liver involvement were identified as risk organs associated with poorer OS, emphasizing their critical role in prognosis.
The presence of risk organ involvement significantly stratified patients' OS, with a hazard ratio of 3.35, indicating a strong prognostic impact.
Patients with more than 6 organ lesions had a median OS of 10.0 months, underscoring the negative impact of extensive organ involvement.
Interpretation:
The study highlights the importance of organ involvement in aggressive ATL, suggesting that specific organs (CNS, lung, liver) significantly impact prognosis and should be considered in risk stratification for improved patient management.
Limitations:
Single-center study may limit generalizability; findings may not apply to broader populations.
Retrospective design may introduce selection bias, affecting the reliability of the results.
Limited data on some organ involvements may affect comprehensive understanding of their prognostic significance.
Conclusion:
Organ involvement, particularly in the CNS, lung, and liver, serves as a critical prognostic factor in aggressive ATL, warranting the development of a new prognostic index to enhance patient management.
