Abstract Background To explore the survival and side effects of repeated CyberKnife stereotactic body radiation therapy (CK-SBRT) on hepatocellular carcinoma patients. Methods 24 HCC patients were collected at The Fifth Medical Center of PLA General Hospital from November 2011 to July 2016. They received second-course CK-SBRT with a prescribed dose of 50(48–55) Gy/5-8fx, and a single dose of 10 (7–11) Gy/fx. Cumulative overall survival rates (OS), progression-free survival rates (PFS) and local control rates (LC) were calculated by Kaplan-Meier method. Results All patients finished their radiotherapy plans. The 1-,2- and 3-year cumulative OS rate were 95.8,81.1 and 60.8%. The 1-,2- and 3-year LC rate were 95.5,90.7 and 90.7%, respectively. The 1-, 2- and 3-year PFS were 74.8, 49.2 and 39.4%, respectively. 16 patients complained of fatigue during second-course therapy, 2 patients showed Grade 2 gastrointestinal reaction, 1 patient was diagnosed radiation-induced liver disease and none died. PFS was significantly higher in the interval time < 12 months group than in the interval time ≥ 12 months group (p = 0.030). Conclusions It is preliminarily believed that re-CK-SBRT is an effective and safe treatment for HCC patients, but the treatment criteria should be strictly controlled.

321 Background: Hepatocellular carcinoma (HCC) incidence continues to increase, but recent improvements in treatment of localized tumors have contributed to modest gains in survival rates. Though transarterial chemoembolization (TACE) and stereotactic body radiation therapy (SBRT) are increasingly used in the management of unresectable HCC, outcomes data regarding the combination of these treatments is limited. Here we report institutional outcomes for patients with Child-Pugh A (CPA) and B HCC treated with TACE followed by SBRT. Methods: We completed an institutional retrospective review of all patients treated with combination TACE and SBRT between 2009 and 2013. After compiling dosimetry, toxicity, and outcomes data for each patient we calculated descriptive statistics for the cohort and determined local control (LC), distant liver control (DLC), progression free survival (PFS), and overall survival (OS) utilizing the Kaplan-Meier method. We also compared these disease-related outcomes between CPA and CPB groups with the Mantel-Cox test for equality. Results: Thirty-one patients with HCC, median age 65, were treated with TACE and SBRT and followed for a median 16.6 months (range: 6.2-50.8). Twenty-two patients had CPA disease and 9 CPB at the time of initial treatment. Following TACE and a median interval of 10.5 days (range: 4.4-25.6) patients underwent SBRT, the majority (23) with 45 Gy in 3 fractions. All but 3 patients were treated with respiratory gating, and all had cone-beam CT for image guidance. One and 2 year disease-related outcomes were as follows: LC 92.0 and 82.8%, DLC 81.5 and 61.0%, PFS 73.6 and 61.8%, OS 96.8 and 64.2%. There were no statistically significant differences between CPA or CPB patients with respect to any of these disease-related outcome measures. Median survival times for class A and B patients were 34.2 months (95% CI 12.3-56.1) and 27.2 months (14.9-39.5) respectively. Conclusions: The combination of TACE and SBRT is generally well tolerated, and results in very good local control in both CPA and CPB patients. Distant liver failure remains a major problem in these patients and requires further study.

Abstract Background: To evaluate the clinical outcomes of patients who received stereotactic body radiation therapy (SBRT) for single viable hepatocellular carcinoma (HCC) at the site of incomplete transarterial chemoembolization (TACE).Methods: Incomplete TACE was defined as (1) evidence of viable HCC at the site of TACE on follow-up images following one or more consecutive TACEs, (2) no definite tumor staining on celiac angiogram, or (3) no definite iodized oil uptake on post-embolization angiogram or computed tomography. A total of 302 patients were treated between 2012 and 2017 at Asan Medical Center (Seoul, South Korea). Doses of 10–15 Gy per fraction were given over 3–4 consecutive days. Treatment-related adverse events were evaluated according to the common terminology criteria for adverse events, version 4.03.Results: The median follow-up duration was 32.9 months (interquartile range [IQR], 23.6–41.7) and the median tumor size was 2.0 cm (range, 0.7–6.9). The local control (LC) and overall survival rates at 3 years were 91.2% and 72.7%, respectively. 95.4% of the tumors reached complete response (CR) during the entire follow-up period (anyCR). The median interval from SBRT to anyCR was 3.4 months (IQR, 1.9–4.7), and 39.9% and 83.3% of the lesions reached CR at 3- and 6-months after SBRT, respectively. Radiation-induced liver disease was observed in 8 (2.6%) patients. No patients experienced gastroduodenal bleeding within the radiation field.Conclusion: SBRT should be considered a feasible salvage treatment option for HCC after incomplete TACE.

AbstractBackground and purposeThe optimal dose and fractionation scheme of stereotactic body radiation therapy (SBRT) for hepatocellular carcinoma (HCC) remains unclear due to different tolerated liver volumes and degrees of cirrhosis. We compared the effectiveness of stereotactic body radiation therapy dosing regimens for hepatocellular carcinoma (HCC).Methods and materialsThis single-center retrospective study included 604 patients treated during 2011-2017. Biologically effective dose (BED10) and equivalent dose in 2 Gym fractions (EQD2) were assumed at an α/β ratio of 10. Overall survival (OS), local recurrence-free rate (LRF), intrahepatic recurrence-free rate (IRF), and progression-free survival (PFS) was evaluated in univariable and propensity-score matched analyses.ResultsMedian tumor size was 5.2 cm (interquartile range [IQR], 1.1-21.0). Median follow-up was 31 months in surviving patients (IQR, 3-82). High radiotherapy dose correlated with better OS, PFS, LRF and IRF. Different post-SBRT OS, PFS, LRF and IRF rates were observed for stereotactic ablative radiotherapy (SART) with BED10 ≥100 Gy, SBRT with EQD2 ≥74 Gy to BED10 <100 Gy, and stereotactic conservative radiotherapy (SCRT) with EQD2 <74 Gy.ConclusionsHigh radiotherapy dose correlated with better outcomes. If tolerated by normal tissue, we recommend SART as a first-line ablative dose or SBRT as a second-line radical dose. Otherwise, SCRT is recommended as palliative irradiation.

Abstract OBJECTIVE To determine the limiting dose to the optic apparatus in single-fraction irradiation in patients with craniopharyngioma treated with gamma knife radiosurgery (GKRS). METHODS One hundred patients with 109 craniopharyngiomas treated with GKRS were evaluated with a median follow-up period of 68 months. Tumor volume varied from 0.1 to 36.0 (median, 3.3) cm3. Marginal doses varied from 10 to 18 (median, 11.4) Gy. Maximum dose to any part of the optic apparatus varied from 2 to 18 (median, 10) Gy. RESULTS The actuarial 5- and 10-year overall rates of survival of tumor progression after GKRS were 93% and 88%, respectively. Similarly, the actuarial 5- and 10-year progression-free survival rates were 62% and 52%, respectively. Among 94 patients in whom visual function was evaluable after GKRS, only 3 patients developed radiation-induced optic neuropathy, indicating an overall Kaplan-Meier radiation-induced optic neuropathy rate of 5%. Of these patients, 2 received 15 Gy or greater to the optic apparatus. Another patient who received 8 Gy or less had undergone previous fractionated radiation therapy with a biologically effective dose of 60 Gy. CONCLUSION The optic apparatus seems to be more tolerant of irradiation than previously thought. Careful dose planning is essential, particularly in patients who underwent prior external beam radiation therapy.

PurposeThis study aimed to evaluate the efficacy and safety of trans-arterial chemoembolization (TACE) followed by stereotactic body radiation therapy (SBRT) in treating Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) not amenable to resection and radiofrequency ablation (RFA).MethodsFrom February 2012 to January 2017, a total of 57 BCLC stage B HCC patients who were unsuitable candidates for resection and RFA treated with TACE combined with CyberKnife SBRT were included in this retrospective study. Patients underwent TACE for a median of two times (1–5 times) before SBRT. SBRT prescription doses ranged from 30 Gy to 50 Gy in 3–5 fractions.ResultsThe median follow-up time was 42 months. The objective response rate (CR + PR) was 85.9%, and the disease control rate (CR + PR + SD) was 96.5%. The local control (LC) rates were 91.1% and 84.3% at 1 and 2 years, respectively. The 1-, 2-, 3-year overall survival (OS) and the median survival time were 73.2%, 51.4%, 32.4% and 26.6 months, respectively. The 1-, 2-, and 3-year progression-free survival (PFS) were 34.2%, 21.6%, and 9%, respectively, with a median PFS time of 9.7 months. A subgroup analysis was conducted in 32 patients with AFP ≥ 200 ng/ml before TACE. OS was significantly prolonged in those with AFP that decreased by more than 75% than those with AFP that decreased by less than 75% (P = 0.018) after SBRT. The treatment was well tolerated with only one patient (1.8%) developed grade 3 gastrointestinal toxicity, and another patient developed non-classical RILD. In multivariate analysis, tumor length ≥ 10 cm and AFP ≥ 200 ng/ml were independent poor prognostic factors for OS.ConclusionThe combination of TACE and Cyberknife SBRT showed optimal efficacy with acceptable toxicity for BCLC stage B HCC.

Purpose: To assess the efficacy and safety of stereotactic body radiation therapy using an abdominal compression technique and modified fractionation regimen (5-10 fractions) in patients with small-sized hepatocellular carcinoma. Methods: A total of 101 patients with small-sized hepatocellular carcinoma treated with stereotactic body radiation therapy using an abdominal compression technique and modified fractionation regimen were registered between June 2011 and June 2019 in our hospital. A total dose of 48 to 60 Gy was applied over 5 to 14 consecutive days. Liver motion was controlled by abdominal compression, and a helical intensity-modified radiation therapy-based stereotactic body radiation therapy administrated in tomotherapy platform. Results: The median follow-up period was 23.2 months (range: 4.1-99.2 months). Complete response and partial response were observed in 63 (62.4%) patients and in 24 (23.8%) patients, respectively. At the time of our analysis, the 1-, 3-, and 5-year local control rates after stereotactic body radiation therapy were 96.1%, 89.0%, and 89.0%, respectively. However, logistic regression analysis revealed no correlation between the biologically effective dose and 3-year local control rates. The 1-, 3-, and 5-year overall survival rates were 96.9%, 69.0%, and 64.3%, respectively. For patients who were treatment-naive, the 1-, 3-, and 5-year overall survival were 96.3%, 82.0%, and 82.0%, respectively. No patients experienced classic radiation-induced liver disease or nonclassic radiation-induced liver disease after stereotactic body radiation therapy completion. Conclusions: When using an abdominal compression technique and modified fractionation regimen (5-10 fractions) based on helical intensity-modified radiation therapy, stereotactic body radiation therapy led to a lower toxicity and comparative rate of local control and overall survival for patients who with small-sized hepatocellular carcinoma.
