Lung cancer immunotherapy is a treatment for lung cancer.

Lung cancer immunotherapy can do how many courses, in fact, there is no standard at this stage, treatment can do, mainly depends on two aspects. The first is to see the efficacy, the second is to see whether adverse reactions can be tolerated. If they can accept the premise of treatment first, if the efficacy is better, can control the tumor, and adverse reactions can be tolerated, this time can continue to immunotherapy. However, even if these two conditions are met, there is no final conclusion on how long it will last. Most clinical studies at this stage use two years, that is to say, they are used for two years first and suspended after two years. However, two years is not an optimal plan. At this stage, it is still being explored. According to the current standard, it is two years. Of course, there are some different ones, such as stage III lung cancer. If you do concurrent chemotherapy and then maintain immunotherapy, you can do it for one year. This is the conclusion of the current research.
