Foundamentally, interventional therapy is an interventional chemotherapy or interventional embolisation therapy. For lung cancer, if it’s non-small cell lung cancer, you need to take 4-6 sessions of interventional therapy. Efficacy will be evaluated every two sessions. It will depend on your cancer staging. The effective rate of interventional therapy varyies from different type of tumor.

For different type of tumor, different stage of cancer, it has different clinical efficiency and remission rate. For example, for lung cancer, if it’s early-stage lung cancer. The five-year survival rate of patient can be 80%-90%. For middle stage of lung cancer, it can be 50%-60%. For terminal lung cancer with widespread metastasis, the survival rate of the patient will be low. It’s about 20%
