The European Organisation for Research and Treatment of Cancer/Mycoses Study Group (EORTC-MSG) criteria for IPA are appropriate for patients with hematological malignancies including leukemia, and our nine patients (22%) were considered to have probable CAPA based on an abnormal thoracic CT scan and positive results of non-cultures analysis: serum GM or anti-Aspergillus IgM Ab, in addition to typical COVID-19 concomitant lesions [13]. This evidence concerns the gene CD40LG and COVID-19.
