One of the most challenging problems in the treatment of glioblastoma (GBM) is the highly infiltrative nature of the disease. Infiltrating cells that are non-resectable are left behind after debulking surgeries and become a source of regrowth and recurrence. To prevent tumor recurrence and increase patient survival. it is necessary to cleanse the adjacent tissue from GBM infiltrates. https://www.roneverhart.com/117-Varick-Street-Tribeca-NY-1914/
