Combined medico-surgical strategy for invasive sino-orbito-cerebral breakthrough fungal infection with Hormographiella aspergillata in an acute leukaemia patient.

Hormographiella aspergillata is a rare causative agent of invasive filamentous breakthrough infection, mostly arising after echinocandin exposure. We report a neutropenic patient who developed a severe sino-orbito-cerebral H. aspergillata infection while receiving empirical caspofungin, successfully controlled by an aggressive strategy associating surgical debridement and combined high-dose regimen of antifungal drugs.

[Molecular characterization of breast cancer in clinical practice]. / Caractérisation moléculaire des cancers du sein en pratique clinique.

Breast cancer involves various types of tumors. The objective of this review was to provide a summary of the main methods currently available in clinical practice to characterize breast cancers at a molecular level and to discuss their prognostic and predictive values. Hormonal receptors expression and the HER2 status are prognostic markers and can also predict the response to targeted therapies. Their analysis through immunohistochemistry is systematical. Ki67 is an effective prognostic marker, but its reliability is debated because of its low reproducibility between laboratories and between pathologists. Commercial genomic signatures are all considered valid prognostic tools and may guide physicians to make therapeutic choices. These signatures are costly and should therefore be restricted to situations in which the use of chemotherapy remains equivocal.
