"drug resistance"

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.

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.
