Adjuvant Stereotactic Body Radiotherapy (SBRT) for Hepatocellular Carcinoma After Hepatectomy With Narrow Margin: a Prospective, Multi-center, Randomized Controlled, Open-labelled, Phase III Study
Study Details
Study Description
Brief Summary
Hepatocellular carcinoma (HCC) is the sixth prevalent malignancy worldwide. Although surgical excision is considered the standard treatment for resectable HCC, a high rate of postoperative recurrence was observed after partial hepatectomy, with a marginal recurrence rate up to 30%. Narrow margin resection may be the most appropriate procedure for centrally located HCC or HCC located near liver capsule because the premise for survival is the conservation of more normal liver parenchyma. Unfortunately, narrow margin resection has been reported to contribute to poor survival outcomes. However, no adjuvant therapy after hepatectomy is generally considered to be effective in reducing post-operative recurrence.
Radiotherapy (RT) has been well used in many solid malignant tumors as an (neo)adjuvant to surgical treatment, including HCC. SBRT has shown encouraging rates of local control for HCC. Compared with standard fractionation radiation, SBRT can achieve more precise delivery of high-dose radiation beams to the lesion, obtaining a much smaller target volume. Meanwhile, it could be finished in a short period which can bring more convenience to patients. Recently, several study and randomized controlled trials revealed the survival benefit of adjuvant RT (IMRT and SBRT) in patients with HCC. A large-sample and high-quality multi-center, randomized controlled, prospective study is warranted to further confirm the efficacy of adjuvant radiotherapy in patients with narrow margin resection, considering the small sample size of above-mentioned studies.
