简要总结
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 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 (neo)adjuvant therapy before (or 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. However, there are still lack of exploration for the efficacy of neoadjuvant SBRT. This study is to analyze the safety of preoperative SBRT followed by hepatectomy for centrally located hepatocellular carcinoma.
