Which stage of cancer should I take Gefitinib for?

Gefitinib (Gefitinib) is usually used to treat non-small cell lung cancer (NSCLC), and the stage and stage of its use are not directly defined by the stage of the cancer, but are determined based on the molecular characteristics of the tumor and EGFR mutations. Here are some common scenarios:

1.EGFRmutation positive: Gefitinib is typically used in patients with non-small cell lung cancer who carry EGFR mutations, regardless of stage. EGFRMutation is a genetic variation that can promote the growth and spread of tumors. Therefore, even at earlier tumor stages, doctors may consider targeted therapy with gefitinib if a patient carries an EGFR mutation.

2.Advanced stageNSCLC: Gefitinib is usually used in advanced non-small cell lung cancer, where the tumor has spread beyond the lungs. This may be because in early-stage disease, other treatments such as surgical resection may be more appropriate, while gefitinib is often used in patients with advanced disease who are not candidates for surgery or other treatments.

3.Treatment sequence: Gefitinib is usually used as first-line treatment, that is, as the first-choice treatment. However, in some cases, it may be an option for subsequent treatment based on the patient's specific circumstances.

Gefitinib was launched in China in 2005. At that time, the price of a box was about 5,000 yuan. Enter medical insurance in China in 2017. The price after medical insurance has dropped a lot. For the specific price after medical insurance, please consult the local hospital pharmacy or the medical insurance bureau. Other versions include original drugs and cost-effective generic drugs. Generic drugs include generic drugs from India, Bangladesh and Laos. The prices vary with different specifications, about 200~800yuan, and the ingredients of generic drugs are basically the same as domestic drugs.
