How long the malignant mucinous liposarcoma can survive is decided according to the patient’s pathologic classification at the time of diagnosis, treatment and the patient’s psychological condition. 1. Pathological typing at the time of diagnosis: the malignant degree of mucinous liposarcoma is relatively high, but the earlier the diagnosis is made, the longer the survival time of the patients relatively speaking, early diagnosis is possible to achieve the survival time of 5-10 years, which can be more than 60%; if it is the late stage sarcoma, after surgery, radiotherapy and other treatments, the result is often difficult to be satisfied, and the survival period of the patients is generally in the time of 3-6 months. 2. Treatment situation: after discovering malignant tumor, early treatment can be given, surgical resection can be carried out, together with radiotherapy, chemotherapy or targeted therapy and other programs to prolong the survival period of patients. 3. Psychological condition of the patient: the psychological condition of the patient can also determine the survival time, if the patient’s psychological condition is better, and can accept the disease he/she is suffering from, the survival time is relatively longer. When malignant mucinous liposarcoma is found, consult the general surgery department of regular hospitals and standardize the treatment under the guidance of professional doctors to avoid delaying the condition.
