The recurrence rate of mucinous adenocarcinoma of lung is between 20-30% in early stage, and higher in late stage. Lung mucinous adenocarcinoma is also a kind of lung cancer and has a certain recurrence rate, which needs to be determined by the stage. Early stage mucinous adenocarcinoma of the lungs is still limited, through radical surgery and radiotherapy, chemotherapy and other treatments, the five-year survival rate of patients can reach 70-80%, which means that the recurrence rate is between 20-30%. However, it is more difficult to treat patients in middle and late stages, and the chances of late recurrence are very high even though they are cured in time, especially in the late stage, where the five-year survival rate is only about 10%, and most of the treatments can only help to prolong the survival time and improve the quality of life.
