Brief Summary:
Liver cancer is a common malignant tumor in China and its incidence rate ranks third and remains high The treatment of liver cancer has made some progress in recent years mainly the progress of radical treatment such as surgery and ablation For liver cancer due to the emergence of molecularly targeted drugs such as sorafenib and immunological checkpoint inhibitors the systemic therapeutic effect of advanced liver cancer is improved and the curative effect is further improved In recent years immunotherapy has become one of the clinical treatment options for cancer T lymphocytes are a cell with cell killing ability in the immune system and programmed death factor 1 PD-1 is an important inhibitory receptor on the surface of T lymphocytes It is known that the ligands of PD-1 are PD-L1 and PD-L2 and studies have found that a variety of tumor cells have high expression of PD-L1 ligand on the surface At present clinical research on target drugs for PD-1 has included dozens of solid tumors or hematological tumors The results of clinical studies that have been completed and the interim results of some studies indicate that anti- PD-1 antibody drugs are more effective and safer than previous treatments Patients with hepatocellular carcinoma HCC often undergo liver cancer resection but the recurrence rate can reach 70 to 100 which seriously affects the treatment outcome and long-term survival rate Early recurrence of liver cancer is mainly related to the invasiveness of the tumor Microvascular invasion non-anatomical hepatectomy AFP greater than 32 ngml tumor diameter greater than 5 cm and incomplete tumor capsule are risk factors for recurrence within 2 years after surgery Hence it is necessary to determine the risk factors for HCC recurrence and the markers for continuous monitoring of anti-tumor response before and after surgery Circulating tumor cells CTCs is an integral part of liquid biopsy and has great potential to change the current treatment modality in the cancer field CTCs are derived from solid tumors and are associated with hematogenous metastasis Therefore analyzing the level of CTC has clinical guiding significance For liver cancer patients overall survival OS tended to be poorer in patients with CTCs Although surgical treatment of liver cancer has benefited most patients with liver cancer monitoring postoperative recurrence further improving the long-term prognosis of liver cancer postoperative detection of CTCs and other related indicators combined with targeted immune and other related treatments for further study It is expected to receive 100 patients 50 treatment groups 50 control groups Patients who underwent immunotherapy after surgery were assigned to the immunotherapy group and patients who were not treated with sorafenib after surgery were classified as the control group All patients underwent 7 CTCs tests immunomagnetic beads negative enrichment-targeted PCR before 7 days after surgery and 1st 3rd 6th 9th and 12th postoperatively All patients were observed from the observation period After the liver cancer resection the patient was observed to have died lost to follow-up or the end of the study
