The number of years a patient can live after four times of thermal perfusion treatment is mainly related to the stage of tumor, treatment and individual patient’s condition, which should be analyzed in specific problems and not be generalized. In general, thermal perfusion is often used in clinical practice for patients with gastrointestinal tumors or gynecological malignancies, and the treatment efficiency is about 20%-30%. For patients with malignant tumor intra-abdominal recurrence, metastasis and malignant ascites, by performing thermal perfusion treatment, it can inhibit the growth and development of tumor without damaging normal tissues, which helps to reduce patients’ pain and prolong their survival. After four times of thermal perfusion treatment, patients’ life expectancy can be extended by about 2-5 years, but the exact survival time cannot be specified. Patients are suggested to visit the medical oncology department of regular hospitals for examination, and can learn the specific situation after four times of thermal perfusion therapy by consulting professional doctors.
