It is possible for peritoneal metastatic cancer to live for 14 years after active treatment, but the probability is low, and the five-year survival rate of general patients is about 5%~10%. Distant metastasis, such as peritoneal metastasis, often occurs when malignant tumor develops into advanced stage, at this time, patients may have clinical manifestations such as abdominal pain, malignant ascites, abdominal mass and so on. Due to the complexity of the disease and the poor physical condition of the patients, most of them are treated by non-surgical therapies such as radiotherapy, chemotherapy and targeted therapy. After active treatment, patients with peritoneal metastatic cancer can often obtain a five-year survival rate of 5%~10%. If the patient has high tolerance to treatment and the metastatic lesions are more limited, the survival time can be prolonged after active treatment, so there is a certain probability of surviving for 14 years.
