Strain comparison of systemic N-nitrosohexamethyleneimine carcinogenesis in BALB/c, SENCAR and CD-1 mice.

abstract：:Glioblastoma multiforme (GBM) is a brain tumor with a high mortality rate. Surgical resection combined with radiotherapy and chemotherapy is the standard treatment for GBM patients, but the 5-year survival rate of patients despite this treatment is low. Immunotherapy has attracted increasing attention in recent years....
