Palliative Radiation Therapy

474 Background: Despite retrospective and prospective clinical trials conveying the efficacy of palliative radiation therapy (RT) to the liver, this modality is not commonly used. The purpose of this project is to evaluate trends, dose schemas, and techniques of palliative RT to the liver in current practice. We aim to identify factors associated with overall survival using patient data from the National Cancer Database (NCDB). Methods: Using the NCDB, we analyzed patients with hepatocellular carcinoma (HCC) diagnosed from 2004-2012 treated with palliative RT. Various patient factors were reviewed and survival analyses were performed. Doses were converted to biological effective dose (BED) to compare the different fractionation schemas. Univariate and multivariate analyses were performed with Kaplan Meier and Cox regression tests. Results: A total of 3,267 HCC patients were identified who were treated with palliative intent. Of these 877 (27%) received radiation therapy and only 138 (4% of total, 16% of RT) received radiation therapy to the liver. For those treated with palliative radiation to the liver, the median age was 61 years. Patients with stages I, II, III and IV disease comprised 15%, 15%, 45%, and 25% respectively. Various dose schema and techniques were used. 38% were treated with advanced radiation techniques (24% stereotactic body radiation therapy (SBRT), 14% Intensity-modulated radiation therapy (IMRT). A total of 79 (57%) patients received 10 or fewer fractions, but 32 (40%) of those were SBRT. The median survival was 4.7 months with 16% mortality at 1 month. On multivariate analysis, stage 3 (HR 2.625, p = 0,013) and stage 4 tumors (HR 2.701, p = 0.018), no chemotherapy (HR 1.743, p = 0.025), and lower radiation dose (HR 0.982, p = 0.003) was associated with worse overall survival. Conclusions: Palliative radiation to the liver is not frequently used in patients with HCC. As a result, there is minimal standardization of dose, modality, or treatment schedule. Better understanding of prognostic factors may help better determine the most appropriate plan for each patient to coordinate treatment length with projected survival.

The Relationship

Purpose. To investigate whether lymphocyte nadir induced by radiation is associated with survival and explore its underlying risk factors in patients with hepatocellular carcinoma (HCC). Methods. Total lymphocyte counts were collected from 184 HCC patients treated by radiotherapy (RT) with complete follow-up. Associations between gross tumor volumes (GTVs) and radiation-associated parameters with lymphocyte nadir were evaluated by Pearson/Spearman correlation analysis and multiple linear regression. Kaplan–Meier analysis, log-rank test, as well as univariate and multivariate Cox regression were performed to assess the relationship between lymphocyte nadir and overall survival (OS). Results. GTVs and fractions were negatively related with lymphocyte nadir (p<0.001 and p=0.001, respectively). Lymphocyte nadir and Barcelona Clinic Liver Cancer (BCLC) stage were independent prognostic factors predicting OS of HCC patients (all p<0.001). Patients in the GTV ≤55.0 cc and fractions ≤16 groups were stratified by lymphocyte nadir, and the group with the higher lymphocyte counts (LCs) showed longer survival than the group with lower LCs (p<0.001 and p=0.006, respectively). Patient distribution significantly differed among the RT fraction groups according to BCLC stage (p<0.001). However, stratification of patients in the same BCLC stage by RT fractionation showed that the stereotactic body RT (SBRT) group achieved the best survival. Furthermore, there were significant differences in lymphocyte nadir among patients in the SBRT group. Conclusions. A lower lymphocyte nadir during RT was associated with worse survival among HCC patients. Smaller GTVs and fractions reduced the risk of lymphopenia.

e16637 Background: Current guidelines lack definitive evidences about the predictive capability of clinical parameters for transcatheter arterial chemoembolization (TACE). The aim of this study was to comprehensively investigate the predictive factor among stage I-IV liver hepatocellular carcinoma (LIHC) patients after TACE. Methods: We investigated the clinical features of 211 stage I-IV patients with LIHC in discover group and 341 patients in validation group. Overall survival (OS) was estimated using the Kaplan-Meier method and the log-rank test. Results: Univariate Cox regression revealed that Monocyte count, TNM stage and AST-to-APOA ratio (AAR) were associated with unfavorable OS. AAR was identified as an independent predictor of OS using multivariate analysis. Kaplan-Meier curve demonstrated that patients with AAR < 50 displayed better prognosis. The median follow-up time was 17.1 (95%CI, 14.4 to 19.3) months, 3-year overall survival was 55.9% in the low AAR group versus 28.6% in the high AAR group, and there was significant difference in OS (Hazard ratio [HR] 0.47, 95%CI 0.33 to 0.67, P < 0.001). The AAR showed predictive ability for OS (12-month, AUC = 0.707). These findings were successfully validated in validation group (HR 0.62, 95%CI 0.46 to 0.84, P = 0.002; 12-month AUC = 0.636). Conclusions: AAR was an independent predictor among LIHC patients after TACE. Patients with lower AAR were optimal candidates for TACE.

Medical records for 20 dogs with histologically confirmed nonsplenic hemangiosarcomas treated with palliative radiation therapy were reviewed to evaluate factors influencing tumor response and survival time. The Kaplan-Meier median survival time of dogs that received palliative radiation therapy was 95 days (range 6 to 500 days). Subjective reduction in tumor size was seen in 14 dogs, with four complete responses. Tumor location was a significant univariate prognostic factor for survival, and dogs with retroperitoneal masses had longer survival times.

Background. The association between human endogenous retroviruses-K (HERV-K) (HML-2) and human disease, including a variety of cancers, has been indicated. However, the function of HERV-K (HML-2) in the progression of hepatocellular carcinoma (HCC) still remains largely unclear.Methods. We detected the expression of HERV-K (HML-2) in 84 HCC tissues and adjacent nontumor tissues by quantitative real-time PCR (qRT-PCR) and analyzed its correlation with the clinical parameters.Result. The HEVR-K level was significantly increased in HCC compared with adjacent normal tissues (P<0.01) which was proved to be significantly associated with cirrhosis (P<0.05), tumor differentiation (P<0.05), and TNM stage (P<0.05). Moreover, the high expression of HERV-K (HML-2) had a poorer overall survival than patients with lower expression by a Kaplan-Meier survival analysis (P<0.01). The multivariate Cox regression analysis indicated that the level of HERV-K (HML-2) was an independent prognostic factor for the overall survival rate of HCC patients. Receiver operating characteristic (ROC) curves demonstrated the diagnostic accuracy of HERV-K (HML-2) expression in HCC (AUC = 0.729, 74.7% sensitivity, and 67.8% specificity).Conclusions. Our results suggested that upregulation of HERV-K (HML-2) in HCC patients was significantly related to cancer progression and poor outcome, indicating that HERV-K (HML-2) might be a novel candidate prognostic biomarker for HCC.

ObjectivesGeographical disparities have been identified as a specific barrier to cancer screening and a cause of worse outcomes for patients with cancer. In the present study, our aim was to assess the influence of geographical disparities on the survival outcomes of patients with nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT).DesignCohort study.SettingGuangzhou, China.ParticipantsA total of 1002 adult patients with NPC (724 males and 278 females) who were classified by area of residence (rural or urban) received IMRT from 1 January 2010 to 31 December 2014, at Sun Yat-sen University Cancer Center. Following propensity score matching (PSM), 812 patients remained in the analysis.Main outcome measuresWe used PSM to reduce the bias of variables associated with treatment effects and outcome prediction. Survival outcomes were estimated using the Kaplan-Meier method and compared by the log-rank test. Multivariate Cox regression was used to identify independent prognostic factors.ResultsIn the matched cohort, 812 patients remained in the analysis. Kaplan-Meier survival analysis revealed that the rural group was significantly associated with worse overall survival (OS, p<0.001), disease-free survival (DFS, p<0.001), locoregional relapse-free survival (LRRFS, p=0.003) and distant metastasis-free survival (DMFS, p<0.001). Multivariate Cox regression showed worse OS (HR=3.126; 95% CI 1.902 to 5.138; p<0.001), DFS (HR=2.579; 95% CI 1.815 to 3.665; p<0.001), LRRFS (HR=2.742; 95% CI 1.359 to 5.533; p=0.005) and DMFS (HR=2.461; 95% CI 1.574 to 3.850; p<0.001) for patients residing in rural areas.ConclusionsThe survival outcomes of patients with NPC who received the same standardised treatment were significantly better in urban regions than in rural regions. By analysing the geographic disparities in outcomes for NPC, we can guide the formulation of healthcare policies.

Abstract Background: Hepatocellular carcinoma (HCC) is the fourth leading cause of cancer-related death worldwide. Steroid 5 alpha-reductase 3 (SRD5A3) was reported to be up-regulated in many types of cancer. However, its expression and role in HCC remains to be elucidated. We aim to evaluate the significance of SRD5A3 expression in HCC by using analysis of a public dataset from The Cancer Genome Atlas (TCGA).Methods: The relationship between clinical pathologic features and SRD5A3 were analyzed with the Kolmogorov‐Smirnov test and the logistic regression. Cox regression and the Kaplan-Meier method were used to assess the clinicopathologic characteristics associated with overall survival (OS) in TCGA patients. In addition, GSEA was used to predict potential hallmarks associated with different expression of SRD5A3 on transcriptional sequences from TCGA database.Results: SRD5A3 was highly expressed in HCC tumor tissue compared to normal tissue. A total of 184 upregulated DEGs (differentially expressed genes) and 58 downregulated DEGs were identified between high expression and low expression of SRD5A3. Among them, 22 hub genes mainly belonging to the keratin and MUC family demonstrated by connectivity degree in the PPI network were screened out. Kaplan-Meier method showed that HCC patients in the high SRD5A3 expression group had poorer overall survival (OS, HR=2.26(1.58-3.24), p<0.001). In addition, cell cycle mitotic, cell cycle checkpoints, mitotic nuclear division, Q-glycan processing, protein O-linked glycosylation were differentially enriched in the high SRD5A3 expression phenotype pathway. In addition, SRD5A3 expression level has significant correlations with infiltrating levels of Th17 (R = -0.238, p < 0.001), Cytotoxic cells (R = -0.234, p < 0.001) and Th2 cells (R = 0.258, p < 0.001) in HCC.Conclusions: High expression of SRD5A3 was significantly correlated with poor prognosis in HCC patients. It may be a potential biomarker in HCC.
