Divide the patients into pre-covid 19 group(2015.01-2019.12) and covid 19 group(2020.1-2023.12) according to the time period.
Objectives:
1.Conduct a comparative analysis in 2015-2020 stage (Pre-Covid Era) and 2020-2024 stage (Covid Era). To summarize and compare the characteristics of Mucormycosis in Chinese hematologic malignancies population from the aspects of incidence, mucorus species, types of mucormycosis, diagnostic techniques, treatment methods (surgical +drugs), pharmaceutical economics and prognosis between two stages. Objectively reflect the current management status of Mucormycosis in this population.
2 Analyze the possible causes of the epidemiology changing of mucormycosis: COVID19 influence, the advancement of diagnostic technology(NGS, respiratory endoscope intervention technique etc.) and other factors.
3 Impact of treatment progress on disease prognosis and burden: the status of surgery changes; To investigate the efficacy, safety and therapeutic status of posaconazole and other antifungal drugs in the treatment of Mucormycosis, and analyze the impact of the new antifungal drugs on the prognosis.
Data collection:
According to the information provided in the medical records and test results, enter the relevant data: including baseline characteristics, complications, clinical manifestations, laboratory tests, bronchoscopy results, imaging findings, fungal prophylaxis medication, therapeutic medication, surgical conditions and prognosis.
Results:
1. Incidence difference of invasive mucormycosis between two stages;
2. Risk factors difference of invasive mucormycosis between two stages;
3. Difference of Clinical types, imaging features and bronchoscopic features of invasive mucormycosis in hematologic malignancies between two stages;.
4. Changing of etiology and histopathological results of invasive mucormycosis in hematologic malignancies between two stages;.
5. History of antifungal drug exposure in hematologic malignancies patients with invasive mucormycosis;
6. Treatment regimen and course changing of invasive mucormycosis
7. Prognosis of invasive mucormycosis in hematologic malignancies patients;
8. Economic burden transition of invasive mucormycosis in hematologic malignancies patients including average length of hospital stay, cost of antifungal therapy etc.
9. Incidence and characteristics of invasive pulmonary mucormycosis in allogeneic hematopoietic stem cell transplantation patients during two stages.
