Abstract No. 499 Association between preoperative selective intra-arterial radiotherapy and overall survival: a retrospective study of patients with hepatocellular carcinoma in the National Cancer Database

Purpose Data that guide selection of optimal local ablative therapy for the management localized hepatocellular carcinoma (HCC) are lacking. Because there are limited prospective comparative data for these treatment modalities, we aimed to compare the effectiveness of radiofrequency ablation (RFA) versus stereotactic body radiotherapy (SBRT) by using the National Cancer Database. Methods We conducted an observational study to compare the effectiveness of RFA versus SBRT in nonsurgically managed patients with stage I or II HCC. Overall survival was compared by using propensity score–weighted and propensity score–matched analyses based on patient-, facility-, and tumor-level characteristics. A sensitivity analysis was performed to evaluate the effect of severe fibrosis/cirrhosis. In addition, we performed exploratory analyses to determine the effectiveness of RFA and SBRT in clinically relevant patient subsets. Results Overall, 3,684 (92.6%) and 296 (7.4%) nonsurgically managed patients with stage I or II HCC received RFA or SBRT, respectively. After propensity matching, 5-year overall survival was 29.8% (95% CI, 24.5% to 35.3%) in the RFA group versus 19.3% (95% CI, 13.5% to 25.9%) in the SBRT group ( P < .001). Inverse probability–weighted analysis yielded similar results. The benefit of RFA was consistent across all subgroups examined and was robust to the effects of severe fibrosis/cirrhosis. Conclusion Our study suggests that treatment with RFA yields superior survival compared with SBRT for nonsurgically managed patients with stage I or II HCC. Even though our results are limited by the biases related to the retrospective study design, we believe that, in the absence of a randomized clinical trial, our findings should be considered when recommending local ablative therapy for localized unresectable HCC.

417 Background: To assess the impact of hospital volume and type on survival in patients with hepatocellular carcinoma (HCC). Methods: Patients with histopathological or imaging-based diagnosis of HCC were identified from the 2003-2015 National Cancer Database (NCDB). First-line treatment was stratified as liver transplant, surgical resection, interventional oncology (IO) and chemotherapy. Hospital volume was stratified as high (ranking among top 10% in case numbers) and low volume, separately for each treatment modality. Hospital type was categorized as academic and non-academic. Overall survival was assessed using multivariable Cox proportional hazards models. Results: A total of 63,877 patients were included (transplant n = 10,596, surgical resection n = 11,132, IO n = 12,286, chemotherapy n = 29,863). Of 1,261 hospitals systems which treated HCC, 226 (17.9%) were academic centers and 1,035 (82.1 %) were non-academic centers. Mean number of cases treated annually was higher in academic centers (55.2; 34.6; 40.7; 79.9) versus non-academic centers (10.7; 6.25; 6.6; 11.9 for transplant; surgical resection; IO and chemotherapy; p < 0.001, respectively). Young African American patients and those with private insurance, high income and education were more likely to receive treatment at academic centers. Geographical difference were evident among US regions, with highest proportion of HCC treated at academic centers in New England states (83.6%) and lowest in South Atlantic states (48.6%). Overall survival was superior for academic versus non-academic centers (HR = 0.89, 95% CI: 0.87-0.91, p < 0.001) and high versus low volume centers (HR = 0.79, 95% CI: 0.77-0.81, p < 0.001), after multivariable adjustment for potential confounders. These effects were evident among all HCC treatment modalities. Conclusions: HCC treatment in academic centers shows distinct patterns according to patient demographics and US geography. Among all treatment modalities, both academic setting and hospital volume independently affected HCC outcomes, with highest patient survival observed in high-volume academic centers.

Objective: To compare the effectiveness, safety and survival outcome of transcatheter arterial chemoembolization (TACE) combined with high-intensity focused ultrasound (HIFU) versus surgical resection for treating single hepatocellular carcinoma (HCC) with Child-Pugh B cirrhosis. Methods: A hospital-based retrospective study with 146 patients diagnosed with single HCC with Child-Pugh B cirrhosis from July 2010 to July 2018 was conducted in a tertiary teaching hospital. A total of 49 patients underwent TACE combined with HIFU (the combined group), and 97 patients underwent surgical resection (the resection group). Of them, 22 patients undergoing TACE combined with HIFU and 45 patients undergoing surgical resection had small HCC (tumor diameter ≤3 cm). The overall survival (OS) time, progression-free survival (PFS) time and postoperative complications were compared between the two groups. Results: In the single HCC tumor cohort, there was no significant difference in OS between the two groups [hazard ratio (HR) = 0.6379; 95% confidence interval (95% CI) = 0.3737 to 1.089; P = .0995], while the resection group showed an obvious superiority to the combined group regarding PFS (HR = 0.3545; 95% CI = 0.2176-0.5775; P < .0001). The 1-year, 3-year and 5-year recurrence rates were 30.9%, 55.7%, 86.6% in the resection group and 53.1%, 77.6%, 89.8% in the combined group, respectively. In the small HCC tumor cohort, there was also no difference in OS between the two groups (HR = 0.8808; 95% CI = 0.3295-2.355; P = .06396), while the resection group showed an obvious superiority to the combined group regarding PFS (HR = 0.4273; 95% CI = 0.1927-0.9473; P = .0363). The 1-year, 3-year and 5-year recurrence rates were 28.9%, 53.3%, 93.3% in the resection group and 40.9%, 68.2%, 81.8% in the combined group, respectively. Furthermore, the incidence of complications of the combined group was 38.8%, which was significantly less than the 56.7% of the resection group ( P = .041), and the duration of general anesthesia in the combined group was shorter than that in the resection group ( P = .001). Therein, there was no difference in the incidence of grade I complications (Clavien-Dindo classification) between the two groups ( P = .866). Conclusion: For patients with single or single small HCCs, TACE combined with HIFU may not be inferior to surgical resection in terms of the long-term survival rate, while surgical resection still has a definite advantage in terms of delaying recurrence. In addition, the combination of TACE and HIFU has higher safety than surgical resection.

Abstract Background Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer. Globally, liver cancer is the 5th and 7th most common cancer in men and women, respectively. Most of HCC burden lies in developing countries. The regions of high incidence include Eastern and South-Eastern Asia, Middle and Western Africa. Worldwide, it is the third most common cause of cancer deaths Aim of the Work A retrospective study of Hepatocellular carcinoma patients presented to Ain Shams University Hospital clinical oncology department between the period of 1/2013 till the end of 12/2016 aiming to review of epidemiological and clinical risk factors, response to the therapy used, progression free survival and overall survival. Patients and Methods The current study is a retrospective analysis carried out in Ain-Shams clinical Oncology and Nuclear Medicine department, Faculty of medicine, Ain Shams University between the period of 1st January 2013 till the end of 2016, where 136 medical records were planned to be analyzed, from which 18 records were not included in analysis (8 records weren’t available in the archive, 10 contained inadequate data) and 118 were analyzed aiming at detection of the prognostic factors, response, progression free survival and overall survival of patients with HCC. Results Regarding age, the median age at diagnosis was 58 years (SD = 8.29), where the average median age was 57.5 years. In our study most of patients were presented with good PS, where 100 (84.7%) of them had performance status less than or equals 2 and only 18 patients (11.8%) were more than or equals 3 performance status < 2 in 84 % of all cases and >2 in 16 %. Conclusion To conclude, age as a prognostic factor significantly affects survival in favor of patients < =58 years. RFA affects survival. Performance status significantly affects survival. The quality of data reported was to some extent impaired due unavailability of complete clinical, analytical and radiological information in the charts.

The Usa

Introduction: Small studies from outside of the USA suggest excellent outcomes after surgical resection for hepatocellular carcinoma (HCC) with vascular invasion. The study aims to (1) compare overall survival after surgical resection and systemic therapy among patients with HCC and vascular invasion and (2) determine factors associated with receipt of surgical resection in a US population. Methods: HCC patients with AJCC clinical TNM stage 7th T3BN0M0 diagnosed between 2010 and 2017 from the National Cancer Database were analyzed. Cox and logistic regression analyses identified factors associated with overall survival and receipt of surgical resection. Results: Of 11,259 patients with T3BN0M0 HCC, 325 (2.9%) and 4,268 (37.9%) received surgical resection and systemic therapy, respectively. In multivariable analysis, surgical resection was associated with improved survival compared to systemic therapy (adjusted hazard ratio: 0.496, 95% confidence interval: 0.426–0.578) with a median survival of 21.4 and 8.1 months, respectively. Superiority of surgical resection was observed in noncirrhotic and cirrhotic subgroups and propensity score matching and inverse probability of treatment weighting adjusted analysis. Asians were more likely to receive surgical resection, whereas Charlson comorbidity ≥3, elevated alpha-fetoprotein, smaller tumor size, care in a community cancer program, and the South or West region were associated with a lower likelihood of surgical resection. Conclusion: HCC patients with vascular invasion may benefit from surgical resection compared to systemic therapies. Demographic and clinical features of HCC patients and region and type of treating facility were associated with surgical resection versus systemic treatment.

Objective: There has been significant changes in management of acute myeloid leukemia (AML) over past few years with bunch of new medications approved for AML management. We did a retrospective study to investigate if the recent improvement in AML management options have led to improved survival in elderly AML pts. Subjects and Methods: Patients with AML from 2004-2014 between age from 60-90 years were included in the retrospective study. Chi-square analysis was used to assess the association between treatment and factors investigated. Kaplan-Meier method was used to assess overall survival. Log rank methods were used to determine factors significant for survival. Multivariable Cox regression analysis was used to determine the independent variables. Results: 37,617 patients from the National Cancer Database were eligible for this study. Twenty-seven, thirty-six and thirty-seven percentage of pts were in the age group more than/equal to eighty, between 70-79 years and 60-69 years, respectively. The median survival in months of pts between 60-69 years, 70-79 years and >= 80 years was 9.5, 3.8 and 1.4 respectively. The median survival of pts did improve the years with median survival of 3.3 m, 3.7 m and 5 m in pts who got diagnosed between 2004-2007, 2008-2010 and 2011-2014 respectively. On multivariate analysis, after adjusting for all variable including age, gender, race, treatment received and comorbidity index, the year of AML diagnosis was statistically significant predictor of overall survival. The pts who got diagnosed between 2011-2014 were 19 % less likely to die compared to those diagnosed between 2004-2007. Conclusion: Survival analysis on AML in the National Cancer Database showed that survival in elderly pts with AML has improved over the years with pts who were diagnosed between 2011-2014 were 19 % less likely to die compared to pts diagnosed between 2004-2007.
