Through the screening of CTCs in patients with suspected liver cancer and liver tumor resection or liver transplantation, the number of CTCs in the blood of liver cancer patients before and after surgery is monitored, and the clinical application significance of CTCs in liver cancer screening and postoperative recurrence monitoring in liver cancer patients is evaluated.

1. Screen patients with suspected liver cancer Long-term exposure to liver cancer risk factors (hepatitis B carriers, past history of schistosomiasis, long-term diet of Aspergillus food, history of liver cirrhosis, etc.), patients with liver cancer are initially suspected.
2. Monitor the number of CTCs in the blood of patients with liver cancer before and after surgery Imaging examinations show that liver space is occupied by patients with suspected liver cancer. Use CTCBIOPSY® technology to monitor patients' surgical operations (including interventional therapy, tumor resection, or liver cancer liver transplantation) at different times 1-3 days before, 1 month after surgery, and 6 months after surgery The number of CTCs in peripheral blood.
3. To evaluate the clinical application significance of CTCs in liver cancer screening and postoperative recurrence monitoring in patients with liver cancer Combined with clinicopathology, tumor marker examination and imaging examination, clinical follow-up and follow-up, analyze the clinical significance of CTCs detection in liver cancer patients, and focus on evaluating the relationship between circulating tumor cells in liver cancer screening and postoperative recurrence, and establish a new The liver cancer prediction model improves the prognosis of liver cancer patients.
