1.Why liver cancer will recur after surgery Liver cancer is a systemic disease. When liver cancer develops to a certain stage, tumor cells may metastasize to other organs (lung, bone, brain, etc.), which cannot be detected by the current examination before liver transplantation, and after surgery, due to the immunosuppression state, the micro lesions latent in other organs may lead to the recurrence of liver cancer. 2.What conditions indicate liver cancer recurrence Liver cancer patients with liver transplantation have elevated AFP before surgery and reduced to normal after surgery, if the AFP is significantly elevated in the re-examination, it indicates liver cancer recurrence. If AFP is normal before surgery, but regular postoperative CT of chest and upper abdomen indicates abnormal lesions and obvious enhancement in enhanced scan or gradual increase in size in follow-up, it indicates recurrence of liver cancer. 3. What methods can prevent recurrence of liver cancer Oral targeted drugs (sorafenib) and intravenous chemotherapy (oxaliplatin, arsenic trioxide); adjuvant application of Sophora granules and thymidine can prevent recurrence of liver cancer. If the recurrence of hepatocellular carcinoma is clear (intrahepatic and intrapulmonary), intrahepatic recurrence can be treated by surgery as much as possible; if surgery is not possible, DSA, ultrasound-guided microwave, radiofrequency ablation, anhydrous alcohol injection and gamma knife radiation can be used; intrapulmonary recurrence can be treated by CT-guided microwave radiofrequency ablation and gamma knife radiation, and oral targeted drug (sorafenib) or intravenous chemotherapy (oxaliplatin, arsenic trioxide) can be used at the same time. Intravenous chemotherapy (oxaliplatin, arsenic trioxide) systemic treatment; adjuvant application of Sophora granules, thymidine. 5.What is chemotherapy, targeted therapy and radiotherapy For liver cancer liver transplant patients, chemotherapy is mainly oral chemotherapy (sorafenib, Sophora granules, capecitabine) and intravenous chemotherapy (oxaliplatin, arsenic trioxide); targeted therapy is mainly oral chemotherapy with sorafenib (doxorubicin); radiotherapy mainly includes gamma knife, radioactive knife and other radiotherapy. 6.What is DSA? Super-selective cannulation through femoral artery to hepatic artery and injection of embolic agent (such as iodine oil) and anti-cancer drugs, which has certain palliative treatment effect and is mostly used for unresectable hepatocellular carcinoma or for diagnostic treatment of undetermined hepatic occupancy nature. 7.What is minimally invasive treatment for liver cancer Minimally invasive treatment for liver cancer mainly includes B-ultrasound guided percutaneous puncture of tumor with radiofrequency, microwave or anhydrous alcohol injection. 8. Can thymus peptide and cordyceps be used after liver transplantation? Yes, they can be used. Clinically, they are mostly used in combination with other therapies, which have better effects on protecting or improving liver function, reducing adverse reactions and improving anti-tumor ability. 9. Can liver transplantation be continued if the recurrence site is in the liver? If the recurrence site is in the liver and there is no tumor invasion in other parts of the body by PET-CT, liver transplantation can be continued. 10. What to do if liver cancer metastasis occurs in other parts In addition to systemic treatment, surgery is preferred for liver cancer metastasis in other parts; if surgery cannot be performed, gamma knife radiation therapy and anhydrous alcohol injection are feasible according to the recurrence site.
