A Real-world Prospective Observational Study on the Efficacy and Safety of L-AmB(Liposomal Amphotericin B) for br- IFD(Breakthrough Invasive Fungal Disease) in Children and Adolescent Patients With Hematological Malignancies Receiving Triazoles or Echinocandins Prophylaxis

The goal of this observational study is to evaluate the efficacy the favorable response rate and safety of L-AmB(liposomal amphotericin B) for the treatment of br-IFD(breakthrough invasive fungal disease) in Chinese children and adolescent patients with hematological malignancies receiving triazoles/echinocandins antifungal prophylaxis. The main question it aims to answer is: 1. Whether the L-AmB have the same efficacy in the treatment of br-IFD in Chinese children and adolescent with hematological malignancies who are receiving triazoles or echinocandins antifungal prophylaxis as in adults(compared with historical data) 2. Whether L-AmB may have better renal safety in Chinese children and adolescent than in adults (compared with historical data). Chinese children and adolescent with hematological malignancies will taking L-AmB as part of their regular medical care for br-IFD. The efficacy and safety data will be recorded.
