It is more common in females, mainly originates from bronchial mucous glands, and can occur in fine bronchial tubes or central airways, and clinically manifests as peripheral type. Chemotherapy is one of the conventional treatment options for lung adenocarcinoma. The vast majority of chemotherapeutic drugs are administered through the injection route.
