How long should I take Osimertinib tablets before stopping the medication?

According to its clinical guidelines, the recommended dose for patients being treated with Osimertinib is an 80 mg tablet once daily, which can be taken with or without food. Patients are treated in the adjuvant setting and are taken until disease recurrence or unacceptable toxicity or for up to 3 years. Patients with metastatic lung cancer are treated until disease progression or toxicity is unacceptable. However, the course of treatment for lung cancer varies among patients, and the specific withdrawal time needs to be determined according to the patient's condition and the doctor's advice. Generally speaking, osimertinib cannot cure lung cancer and can only control the progression of the disease to a certain extent.
