Can lung adenocarcinoma live for three years?

Lung cancer is a malignant tumor of the respiratory system. Among lung cancer, the most common are lung adenocarcinoma and lung squamous cell carcinoma. For lung adenocarcinoma, in addition to conventional radiotherapy and chemotherapy, targeted drug therapy can also be considered. Gene testing is generally done. If EGFR gene mutation is present, Iressa and Tarceva can be used for treatment. If effective, survival can be significantly prolonged. For other lung adenocarcinoma that cannot be treated with targeted therapy, conventional chemotherapy is mainly pemetrexed plus platinum regimen, which is also effective. Therefore, we should look at it while treating.
