Abstract

Purpose

For patients with hepatocellular carcinoma (HCC), stereotactic body radiation therapy (SBRT) has emerged as a locoregional treatment. Our purpose was to report outcomes in patients with HCC with Child-Pugh A (CP A) versus Child-Pugh B or C (CP B/C) liver dysfunction treated with SBRT.

Methods and Materials

A retrospective analysis of 80 patients with HCC, with a total of 94 tumors treated with SBRT, was conducted at a single institution. Outcomes were compared between patients with CP A (n = 51) and CP B/C (n = 29) liver dysfunction. Outcomes of interest included local control, overall survival (OS), and toxicity.

Results

Median tumor size was 3.2 cm. There were 59 tumors included in the CP A cohort and 35 tumors in the CP B/C cohort. Median radiation dose was 50 Gy in 5 fractions for the CP A cohort and 40 Gy in 5 fractions for the CP B/C cohort. The rates of pathologic complete response were similar between the 2 groups at 63% for the CP A group and 61% for the CP B/C group. The estimated 1-year local control rates were similar between the 2 groups at 93% for the CP A group and 91% for the CP B/C group (P = .59). The 1-year OS for the CP A group was 85%, whereas the 1-year OS for the CP B/C group was 61% (P = .19). There was a 5.9% rate of grade 3+ toxicity in the CP A group and a 20.7% rate of grade 3+ toxicity in the CPB/C group.

Conclusions

Our findings suggest that SBRT is feasible and effective in patients with both CP A and CP B/C liver dysfunction with similar rates of local control and pathologic complete response despite lower radiation doses in the CP B/C cohort. In patients with more advanced CP B/C cirrhosis, toxicities were higher and must be weighed against possible treatment benefits. Further studies characterizing the optimal role of SBRT in patients with advanced cirrhosis are warranted.

Child-Pugh A 与 Child-Pugh B/C 肝硬化患者肝细胞癌立体定向体放射治疗后的疗效比较

目的对于肝细胞癌（HCC）患者，立体定向体放射治疗（SBRT）已成为一种局部治疗方法。我们的目的是报告Child-Pugh A（CP A）与Child-Pugh B或C（CP B/C）肝功能异常的HCC患者接受SBRT治疗后的疗效。方法和材料一家医疗机构对80例HCC患者进行了回顾性分析，共有94个肿瘤接受了SBRT治疗。比较了 CP A（51 例）和 CP B/C（29 例）肝功能异常患者的治疗结果。结果平均肿瘤大小为 3.2 厘米。CP A队列中有59个肿瘤，CP B/C队列中有35个肿瘤。CP A队列的中位放射剂量为50 Gy（5次/分），CP B/C队列的中位放射剂量为40 Gy（5次/分）。两组的病理完全反应率相似，CP A 组为 63%，CP B/C 组为 61%。两组的估计 1 年局部控制率相似，CP A 组为 93%，CP B/C 组为 91%（P = 0.59）。CP A 组的 1 年 OS 为 85%，而 CP B/C 组的 1 年 OS 为 61% (P = .19)。结论我们的研究结果表明，SBRT 对 CP A 和 CP B/C 肝功能不全患者是可行且有效的，尽管 CP B/C 组群的放射剂量较低，但其局部控制率和病理完全反应率相似。在 CP B/C 晚期肝硬化患者中，毒性较高，必须与可能的治疗效果进行权衡。有必要进一步研究 SBRT 在晚期肝硬化患者中的最佳作用。
