ABSTRACT
Background:
Hemophagocytic lymphohistiocytosis (HLH) is a rare but life-threatening clinical syndrome characterized by immune hyperactivation. Unlike primary HLH, immune checkpoint inhibitor (ICI)-triggered HLH is not well described, and there is a lack of theranostic guidelines. Herein, we first reported the successful management of PD-1 inhibitor-associated HLH in locally advanced cervical cancer. Case presentation We report a case of HLH in a 47-year-old patient with International Federation of Gynecology and Obstetrics (FIGO) IIIC1r cervical cancer who received toripalimab, a programmed cell death-1 receptor inhibitor, combined with chemoradiotherapy. The patient developed pyrexia, splenomegaly, leukopenia, anemia, thrombocytopenia, hypertriglyceridemia, hypofibrinogenemia, hyperferritinemia, reduced NK cell activity, elevated sCD25 levels, and hemophagocytosis in a bone marrow aspirate. Our patient was successfully treated with methylprednisolone, indicating that immune-induced HLH might respond to glucocorticoids, and is still alive with a complete response of the tumor.Conclusion:
Considering the possibility of HLH is needed in patients receiving ICIs to detect rare toxicities at an early stage when the patient develops uncontrollable fever, cytopenia, and splenomegaly, our multidisciplinary treatment modality contributed to the early diagnosis and successful management of HLH, avoiding progressive tissue damage and organ failure. Whether glucocorticoids are used alone or not for immune-associated HLH needs further investigation.
