Long-term therapy with bevacizumab in a young patient affected by NF-2: a case report and review of the literature

Long-term therapy with Bevacizumab in a young patient affected by NF2. Stop or continue treatment? An update of a case report and review of the literature

Neurofibromatosis type 2 (NF2) is an autosomal dominant condition caused by pathogenic variants in the NF2 gene. To date, cytotoxic chemotherapy has no established role in the treatment of NF-2. Historical case reports of malignant schwannomas have documented responses to chemotherapies with cyclophosphamide, vincristine and doxorubicin, in patients who develop pulmonary metastases. Recently, several studies proposed the use of anti-HER2, anti-EGFR, anti-platelet-derived growth factor receptors. As reported in our previous review of the literature, vascular endothelial growth factor (VEGF) and its receptor VEGFR-1 have been detected in schwannomas with the best results. We described the case of a young patient with NF2 treated for long time with Bevacizumab. Here, we report the update of the previous case report.
