"drug resistance"

Many lung cancer patients will be detected by genetic testing to carry an EGFR mutation, and these patients can often control their tumours with EGFR-targeted drugs. Although targeted drugs are effective and have fewer side effects than chemotherapy, resistance to them inevitably occurs, after which they no longer work.

Immunotherapy has been a very important treatment in recent years, with many patients in lung cancer, malignant melanoma and many other cancers experiencing dramatic improvements in prognosis with this cutting-edge therapy. In pancreatic cancer, however, progress in immunotherapy has been very slow and its effectiveness has been extremely limited.
