The prognosis of liver cancer patients is often not necessarily related to blood in stool, but blood in stool may indicate portal hypertension, abnormal coagulation function, gastrointestinal metastasis, tumor invasion of bile ducts, etc. If it is in the advanced stage, the survival period is often several months to one year, but the exact survival period varies from person to person. Blood in stool is not a common clinical symptom of liver cancer patients, which may be related to patients’ portal hypertension (which may lead to upper gastrointestinal bleeding), abnormal coagulation function (severe liver damage or malignant disease, etc.), gastrointestinal metastasis, tumor invasion of bile ducts, etc.; usually, the patients are already in advanced stage. Patients with advanced hepatocellular carcinoma are usually in serious condition, which can be combined with anemia, hypoproteinemia, malignant ascites, progressive decline of liver function, etc., and the presence of metastasis, such as intrahepatic metastasis, lymph node metastasis, distant metastasis, etc.; in addition, some patients can develop spontaneous peritonitis, induced hepatic encephalopathy, etc.. Cancer prognosis is generally assessed by survival rate, and liver cancer prognosis is related to disease progression, treatment program, general condition and other factors. Domestic studies claim that the 1-year survival rate of advanced liver cancer is only about 20%, and other studies claim that the average survival time of patients with hepatocellular carcinoma combined with distant metastases is about 13 months; however, there is no recognized definitive conclusion yet. It is recommended that patients diagnosed with liver cancer should go to regular hospitals to evaluate their conditions and follow the doctor’s instructions to cooperate with the treatment, so as to control the progression of the disease and improve the prognosis of the patients.
