Problems solved by technology

There are few drugs used for chemotherapy of glioma, and the existing chemotherapy drugs are nitrosoureas such as nitrosourea alkylating agents carmustine (BCNU) and nitrosourea (CCNU), or PVC scheme ( procarbazine + vincristine + CCNU), but its disadvantage is that the plasma half-life is very short; the side effects are large, and it has the effects of delaying and accumulating bone marrow suppression and pulmonary toxicity; Re-treatment is ineffective
Malignant melanoma is also a relatively common cancer with a high degree of malignancy. The conventional chemotherapy drugs are BCNU and CCNU, but these drugs also have problems such as poor curative effect, large toxic and side effects, and easy drug resistance.
