Left upper lung infiltrative lung adenocarcinoma is defined as a tumor located in the left upper lung with a pathological staging of infiltrative lung adenocarcinoma.
Lung cancer is a common primary malignant tumor of the lung, which can be divided into two categories: non-small cell carcinoma and small cell carcinoma. Adenocarcinoma belongs to one kind of non-small cell lung cancer, which is the most common type of lung cancer, mainly originated from bronchial mucous glands. Clinically, it is mostly manifested as peripheral type.
Lung adenocarcinoma is further subdivided into adenocarcinoma in situ, minimally invasive adenocarcinoma, invasive adenocarcinoma, and invasive adenocarcinoma variant. Among them, invasive adenocarcinomas include wall-like growth-predominant, vesicular-predominant, papillary-predominant, and solid carcinoma with mucus formation.
Early-stage invasive lung adenocarcinoma can be removed by surgery, while progressive or metastatic lung adenocarcinoma can be treated with radiotherapy, targeted therapy and immunotherapy to slow down the disease progression.
When left upper lung invasive lung adenocarcinoma occurs, it is recommended to seek medical treatment in time and standardize the treatment under the guidance of professional doctors.
