Most minimally invasive adenocarcinomas are early stage and are treated mainly by surgery. The middle and late stages are mainly treated with drug chemotherapy. The therapeutic effect varies from person to person. Microinvasive adenocarcinoma means that the tumor infiltrates more than the basal layer, but the depth of infiltration is not more than 5mm. As an early stage lung cancer, it has a certain degree of infiltrative nature, but it can be cured by early radical surgery, and the patient does not need other auxiliary treatments after the surgery, and regular follow-up is enough. If the patient’s condition is more serious, combined treatment can be considered, and commonly used treatments mainly include radiation therapy, chemotherapy, biotargeted therapy and so on. If microinvasive adenocarcinoma is diagnosed, patients should seek medical treatment in time and under the guidance of doctors.
