4080 Background: Stereotactic Body Radiation Therapy (SBRT) has emerged as a viable treatment option in patients with hepatocellular carcinoma (HCC). This study aimed to compare survival outcomes after SBRT with other front line local treatments for HCC. Methods: This is a retrospective analysis of patients identified through our cancer registry from 2000 to 2016. Patients treated with any local therapy alone were eligible: SBRT, surgery, conventional external beam radiation (CEBRT), and other local therapies including brachytherapy. Patients treated with combined therapies such as SBRT plus liver transplant were excluded. The primary endpoint was overall survival which was estimated from the time of diagnosis. Differences between the groups were compared using log-rank test. The data are presented as median (95%CI). Results: A total of 756 patients with a median follow-up of 45 months (mo) met the selection criteria: 116, 380, 43, and 217 patients received SBRT, surgery, CEBRT, and other local treatment, respectively. Median age was 61, 60, 61 and 60 years, respectively. The median overall survival/3 year overall survival rate were 49 (32-66) mo /53% (44-65%) for patients treated with SBRT, which were not significantly different from 75 (57-94) mo /63% (58-69%) of surgery (p = 0.27), non-significantly better than 22 (13-31) mo /41% (27-60%) of CEBRT (p = 0.13), significantly better than 15 (13-20) mo /26% (20-34%) of other local treatments (p = 3×10-7). After adjusting for significant prognostic factors including age, race, status of tobacco abuse, history of alcohol use, tumor size, histology grade and stage, the survival outcomes of SBRT remained to be insignificantly different from surgery (HR = 0.8, p = 0.2), have a trend of significant difference from CEBRT (HR = 1.4, p = 0.1) and remarkably superior to that of other local treatments (HR = 1.8, p = 2×10-4). Conclusions: This study suggests that SBRT is an excellent front line option for HCC, potentially comparable to surgical resection and associated with longer survival than other front line local treatments. Randomized studies are needed to validate these findings.

e15592 Background: Stereotactic body radiation therapy (SBRT) has become a treatment for hepatocellular carcinoma (HCC) from palliative to radical treatment. But there is no clear evidence of a dose-survival relationship among commonly-utilized radiation therapy schedules. We aimed to determine the comparative effectiveness of different SBRT dosing regimens for HCC. Methods: The dataset collected from Guangxi Zhuang Autonomous Region in China was used. In this large single-centered retrospective study, 604 patients treated with SBRT were included from 2011 to 2017. Biologically effective dose (BED10) and equivalent dose in 2 Gy fractions (EQD2) were assumed at an α/β ratio of 10. Overall survival (OS) was the primary endpoint. OS rates were estimated using Kaplan–Meier curves with a log-rank test. Results: The median tumor size was 5.2 cm (interquartile range [IQR], 1.1–21.0 cm). Median follow-up was 21 months in surviving patients (IQR, 3–82 months). The 1-, 3-, and 5-year OSs were 87.1%, 64.7%, and 60.9% in Barcelona Clinic Liver Cancer (BCLC)-A group; 72.9%, 37.2%, and 30.7% in BCLC-B group; and 44.3%, 18.6%, and 12.8% in BCLC-C group; respectively. Increasing the RT dose was associated with improved overall survival. Stereotactic ablative radiotherapy (SART) with BED10≥100 Gy, SBRT with EQD2≥74 Gy and BED10 < 100 Gy, and stereotactic conservative radiotherapy (SCRT) with EQD2< 74 Gy have 3 separate curves for long-term survival post-SBRT. On multivariate analysis, Clinical factors associated with improved OS were BED, alanine aminotransferase (ALT) , and BCLC stage. On the subgroup analysis, BED10 ≥100 Gy was still beneficial against HCCs of BCLC stage A, B, and C. Conclusions: Individualized dose for SBRT are recommended for the treatment of HCC due to different degrees of cirrhosis and liver volume. The RT dose was classified into three levels. If tolerated by normal tissue, SART with BED10 ≥100 Gy as a first-line ablative dose or SBRT with EQD2 ≥74 Gy as a second-line radical dose is recommended. Otherwise, SCRT with EQD2< 74 Gy is recommended as palliative irradiation.

AbstractBackgroundStereotactic body radiation therapy (SBRT) is a treatment option for patients with early-stage non-small cell lung cancer who are medically inoperable or decline surgery. Here we compare the outcome of patients with centrally located lung tumours who underwent either single fraction (SF)- or five-fraction (FF-) SBRT at a single institution over 5 years.MethodsBetween January 2009 and October 2014, patients with centrally located lung tumours who underwent SBRT were included in this study. Data were retrospectively collected using an institutional review board-approved database. For analysis, the Kaplan–Meier method and competing risks method were used.ResultsIn total, 11 patients received 26–30 Gy in 1 fraction, whereas 31 patients received 50–60 Gy (median 55 Gy) in 5 fractions. After a median follow-up of 12 months for SF-SBRT and 17 months for FF-SBRT groups (p=0·64), 1-year overall survival rates were 82 and 87%, respectively. SF- and FF-SBRT groups showed no significant difference in grade 3+ toxicity (p=0·28). The only grade 4 toxicity (n=1) was reported in the SF-SBRT group. All toxicities occurred >12 months after the SBRT.ConclusionsSF- and FF-SBRT have comparable overall survival. SF-SBRT may have some utility for patients unable to have multi-fraction SBRT.

350 Background: To report outcomes of pooled data from patients with early stage hepatocellular carcinoma (HCC) treated with stereotactic body radiation therapy (SBRT) at two North American Institutions. Methods: An IRB approved collaborative review of patients with HCC treated with radical intent SBRT was conducted. Inclusion criteria included patients with Stage I-IIIA HCC (UICC/AJCC 7th Ed.) treated with SBRT (≥ 4.5 Gy/ fraction) from June 2003 until Dec 2016. Patients who were treated with SBRT were ineligible for resection, percutaneous ablative or hepatic intravascular therapies. Patients with vascular invasion and those treated with palliative intent (e.g. HCC rupture) were excluded. Overall survival, local control and toxicity of treatment were reviewed retrospectively. Results: Of 310 eligible patients, 23% were Child-Pugh (CP) class B/C (21%/2%), and 40% had failed prior liver directed therapies. The median HCC diameter was 2.4 cm (range 0.5-18.1 cm), and the median prescribed dose was 39 Gray (Gy) in 5 fractions (range: 14 - 60 Gy in 2-6 fractions). Median BED was 78.75 Gy (Range: 23.8-180.0 Gy). 8.4% of patients underwent liver transplant after SBRT. Local control at 1, 3 and 5 years was 91.5%, 82.6% and 82.6%. On multivariable analysis (MVA), the use of breath-hold motion management, but not T stage, size or dose, was significantly associated with local control (p = 0.0098). The 1, 3, and 5 year overall survival (OS) was 77.3%, 37.9% and 23.5%. Factors associated with improved OS on MVA included baseline CP A score (HR = 0.58, p < 0.0045), AFP < 10 µg/L (HR = 0.66, p = 0.0094), and transplant post SBRT (HR = 0.05, p < 0.0001). The median survival of CP A vs. B/C patients was 30.3 and 17.6 months respectively. CTCAE (v4.0) grade 3 or higher luminal gastrointestinal organ toxicity occurred in 2.5% of patients, while a decline in CP score ≥ 2 points was seen in 16.7% of patients at 3 months post SBRT. Grade 3 and above elevated liver enzymes were seen in 12.6% and 8.1% of patients at baseline and at 3 months post SBRT. Conclusions: Similar to Asian series, this North American pooled analysis found high sustained local control and excellent survival in patients with early stage HCC treated with SBRT.

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.

e17054 Background: Conventionally fractionated radiotherapy (CFRT) or moderately hypofractionated radiotherapy (MFRT) ± short-course androgen deprivation therapy (ADT) is commonly employed for unfavorable intermediate-risk (UIR) prostate cancer. Stereotactic body radiation therapy (SBRT) has not been widely adopted, but may have radiobiologic advantages over more conventionally fractionated treatments. We hypothesized that radiotherapy dose-escalation with SBRT (35-40Gy in ≤5 fractions) is associated with improved overall survival (OS) relative to biologically equivalent doses of CFRT (72-86.4Gy in 1.8-2.0Gy/fraction) or MFRT (≥60Gy in 2.4-3.2Gy/fraction) ± ADT. Methods: The National Cancer Database (NCDB) was used to identify 28,028 men with UIR prostate cancer who received CFRT with (n = 12,872) or without ADT (n = 12,984), MFRT with (n = 251) or without ADT (n = 281), and SBRT with (n = 212) or without ADT (n = 1,428). SBRT+ADT patients were excluded due to low patient numbers. Inverse probability of treatment weighting was used to balance measured confounders. Unweighted- and weighted- multivariable analysis (MVA) using Cox regression was used to compare OS hazard ratios. Results: Relative to CFRT without ADT, CFRT+ADT (Hazard Ratio (HR): 0.92, [95% Confidence Interval: 0.87-0.97], P = .002) and SBRT without ADT (HR: 0.74 [0.61-0.89], P = .002) were both associated with improved OS on MVA. Relative to CFRT+ADT, SBRT without ADT correlated with improved OS on MVA (HR: 0.81 [0.67-0.99], P = .04). Weight-adjusted MVA demonstrated that SBRT (HR: 0.80 [0.65-0.98], P = .036) and ADT (HR: 0.91 [0.86-0.97], P = .002) correlated with improved OS. SBRT was not associated with improved OS relative to MFRT. Conclusions: Using inverse propensity treatment weighting, we adjusted for age, comorbidity score, and tumor factors, and observed a significant overall survival benefit in favor of administering dose-escalated SBRT over CFRT+ADT. To our knowledge, this is the first study to show that SBRT is associated with improved OS relative to CFRT for men with UIR prostate cancer. Together, this suggests that SBRT offers a cheaper and shorter course of therapy that mitigates COVID-19 exposure, which also is associated with improved OS relative to CFRT for UIR prostate cancer and may obviate the need for ADT in this population. While we await results from several ongoing clinical trials, we believe this study lends support to the use of SBRT in men with UIR prostate cancer.
