Summary

Hepatocellular carcinoma is one of ten leading cancer types worldwide and also in Asia, but the five-year relative survival rate is relatively quite low1-3. For hepatocellular carcinoma treatment, current options are surgical resection, embolization chemotherapy, radiation therapy, a variety of ablation therapy, biological and gene therapy, etc. Among them, the use of radiation therapy is getting more and more attention, and it is changing from the past palliative treatment to current curable treatment. From an oncologic point of view, a narrow margin \<1 cm and microvascular invasion is not safe and is often associated with higher rates of recurrence and shorter patient survival.On the other hand, it is also believed that most intrahepatic recurrences arise from multicentric carcinogenesis and are distant from the resection margin. To address this issue, the investigators are going to conduct a series of retrospective and prospective studies to investigate the effect of adjuvant Radiotherapy for centrally located hepatocellular carcinoma after narrow margin (\<1 cm) hepatectomy on tumor recurrence.

Conditions

Interventions

RADIATION

Postoperative radiotherapy

The radiotherapy group received prophylactic radiotherapy 1 month after operation. All the patients in the experimental group were treated with 6 to 8 MV X-ray, intensity-modulated irradiation (IMRT) technique, which was divided into 4-5 fields, 2Gy/25 times. 5f/W, total dose 50Gy

DRUG

Postoperative TACE

In the intervention group, TACE was performed in January and March after operation. The femoral artery puncture was performed by Seldinger method, and the cannula was intubated to the hepatic artery by DSA. Then, 50 mg of lobaplatin plus 4 mg of raltitrexed was injected into the vascular artery. The embolic agent was selected as 38.0. % super liquefied iodine solution and / or gelatin sponge particles, the dose is maintained at 5 \~ 20ml. At the end of treatment, a DSA examination again confirmed that the tumor was completely occluded.
