Brain tumor
Glioblastoma multiforme (GBM) is the most aggressive (grade IV) and most common form of a malignant brain tumor. Even when aggressive multimodality therapy consisting of radiotherapy, chemotherapy, and surgical excision is used, median survival is only 12–17 months. Standard therapy for glioblastoma multiforme consists of maximal surgical resection of the tumor, followed by radiotherapy between two and four weeks after the surgical procedure to remove the cancer, then by chemotherapy, such as temozolomide. Most patients with glioblastoma take a corticosteroid, typically dexamethasone, during their illness to relieve symptoms. Experimental treatments include targeted therapy, gamma knife radiosurgery, boron neutron capture therapy and gene therapy.
Acute megakaryoblastic leukemia
In a review of 153 patients treated for non-DS-AMKL between 1990 and 2014 with various intensive chemotherapy protocols that included cytarabine, an anthracycline (e.g. daunorubicin, doxorubicin), and in 25% of cases human stem cell transplantation, the probability of overall 4 year survival rate, probability of 4 year event-free survival, and probability of 4 year cumulative relapse rate were 56, 51, and 29%, respectively. Patients with non-DS-AMKL given the treatment regimen described for DS-AMKL above had a much better prognosis than patients treated with earlier-devised treatment regimens: their overall survival rate using these regimen was estimated to be 76%.
