A Two-Arm, Multicenter, Non-Randomized Controlled Study on the Efficacy of Yttrium-90 (Selective Internal Radiation Therapy) Therapy and Hepatic Arterial Infusion Chemotherapy (Hepatic Artery Infusion Chemotherapy) for Potentially Resectable Intermediate and Advanced Hepatocellular Carcinoma

Step 1: The MDT team conducts a routine preoperative assessment. Step 2: The interventional team performed tumor vascularity distribution and 99mTc simulation surgery. Step 3: Nuclear Medicine performs SPECT validation and yttrium-90 treatment activity calculation. Step 4: Infusion of yttrium-90 microspheres in the interventional department. Step 5: Nuclear Medicine uses PET/CT or SPECT to determine the distribution of nuclides. If the patient is unwell, he or she can be discharged after 24 hours without special protection. Follow-up examination 1 month after surgery, and then every 2 months, a total of 1 course of treatment. After yttrium-90 treatment, rest for 3-4 months, and arrange hepatectomy after excluding surgical contraindications. The patients in both groups were consulted and discussed by multidisciplinary experts in liver cancer, and elective hepatectomy was arranged after excluding surgical contraindications according to the standardized process.

After successful percutaneous hepatic artery cannulation, superior mesenteric arteriography and hepatic arteriography are performed, and after the hepatic artery is cannulated to a predetermined position, the patient is returned to the ward with an indwelling catheter. In the ward, a catheter syringe pump is continuously pumped into the following chemotherapy drugs: oxaliplatin 135mg/m2 over 3hrs, leucovorin 400mg/m2 over 1.5hrs, 5-FU 400mg/m2 over 2hrs, 5-FU 2400mg/m2 over 46hrs. After the chemotherapy is completed, the catheter is removed, and the patient can be discharged after 12 hours of compression bandaging to stop the bleeding. Repeat at intervals of 3\~4 weeks, a total of 2 or 4 strokes. For details, see 3.3.1.4 Grouping and Treatment Flow Chart. After the end of HAIC, rest for 3\~4 weeks for re-examination, and arrange liver resection after excluding surgical contraindications.
