Phase II Study of Adjuvant Simultaneously Integrated Boost Radiotherapy Following Narrow-Margin Hepatectomy in Patients With HCC.
This is a single-arm prospective phase II clinical trial to investigate the efficacy and safety of adjuvant simultaneouslyintegrated boost radiotherapy following narrow-margin(\<1cm) hepatectomy in patients with HCC. Eligibility patients will receive IMRT or VMAT to high risk area of tumor bed and tumor bed. The prescription dose to 95% GTVtb boost was planned at 55-60Gy, with PTV 45-50Gy, in 23-25 fractions, mainly depending on the dose constraints of OARs. The primary endpoint is the 3-year OS, the secondary endpoints are disease-free survival, patterns of failure, toxic events and local control rate.
• Pathological diagnosis of HCC after hepatectomy with narrow pathological margins (\< 1 cm)
