Primary liver cancer is one of the common malignant tumors in China, of which hepatocellular carcinoma (HCC) accounts for 85%-90%. It is worth noting that the recurrence rate of liver cancer is greater than 10% at 1 year after surgery, while the recurrence rate in 5 years reaches 70-80%.
Stereotactic body radiation therapy (SBRT) refers to a kind of radiotherapy technology to achieve a steep dose gradient and achieve high-precision position and high-dose fractionated irradiation. The rapid dose drop-down enables SBRT to maximize the protection of normal tissues around the tumor, and it often requires only 1-5 times of high-dose fractionated irradiation to complete the course of treatment.SBRT may play an important role in the treatment of small intrahepatic recurrence HCC, but there is still a lack of evidence of high-level prospective studies.
We intend to conduct a single-center, prospective, clinical study to further elaborate the efficacy and safety of SBRT in the treatment of small intrahepatic recurrent HCC.
