4103 Background: Historically, the AJCC esophageal staging system separated patients into prognostic groups based on tumor, node, and metastasis (TNM) classifications. In 2010, the 7th edition (AJCC 7) significantly modified esophageal squamous cell cancer (ESCC) staging by separating ESCC from adenocarcinoma, incorporating tumor grade and location for node negative cancers, and stratifying by the number of involved regional nodes for node positive cancers. Our study aim was to determine whether AJCC 7 stage groupings provide improved survival prognostication compared to 6th edition (AJCC 6). Methods: We abstracted pathology and survival for 150 consecutive ESCC patients who underwent esophagectomy (1994-2012); 44 patients received induction therapy. AJCC 6 and AJCC 7 stages were assigned and overall survival analyzed from esophagectomy to death or most recent alive contact and censored at 60 months. Discriminatory ability and homogeneity within subgroups was assessed with Kaplan-Meier curves and monotonicity comparisons were evaluated with linear trend chi-squared tests. Overall survival was compared using Cox regression and Akaike Information Criterion (AIC) used to assess model fit. Results: Compared to AJCC 6, AJCC 7 upstaged 32 patients from IIa to IIb and 1 patient from IIb to IIIa and downstaged 3 patients from stage IIa to Ib. AJCC 7 subclassified 42 AJCC 6 stage III patients (17 IIIa, 10 IIIb and 15 IIIC). Median overall survival was 19 months. Kaplan-Meier log-rank statistic indicated stronger differentiation in AJCC 7 (19.8 vs 29.7). Cox regression likelihood (19.5 vs 26.1), AIC (618.1 vs 611.6), and linear trend chi-squared at 24- (17.5 vs 24.3) and 60-months (13.3 vs 17.3), were all superior for AJCC 7 stage groupings (AJCC 6 vs AJCC 7, respectively). Conclusions: AJCC 7 stage groupings demonstrate superior homogeneity, discriminatory ability and monotonicity compared to AJCC 6. Incorporating the extent of nodal disease, tumor location and tumor grade into the revised AJCC 7 stage classification improves prognostic stratification of surgically resected ESCC patients, including patients who received induction therapy.

Esophagogastric Adenocarcinoma

92 Background: AJCC esophageal staging assigns prognostic groups based on tumor, node, and metastasis classifications. In 2010, AJCC 7th ed. separated adenocarcinoma from squamous cell histology and added tumor grade and number of involved regional nodes. Our study aim was to compare survival prognostication for esophagogastric adenocarcinoma between AJCC 7 and AJCC 6thed. stage groupings. Methods: We abstracted pathology and survival for surgically-resected esophagogastric adenocarcinoma patients (n=836; 1997 to 2011); 256 received induction therapy. AJCC stage was assigned; overall survival in months (esophagectomy to death or most recent alive contact) was analyzed. Discriminatory ability and homogeneity, by stage, was assessed with Kaplan-Meier (KM) curves. Monotonicity comparisons were evaluated with linear trend chi-squared tests. Overall survival was compared using Cox regression and Akaike Information Criterion (AIC) was used to assess model fit. Results: Compared to AJCC 6, AJCC 7 restaged 165 patients. (Table) KM log-rank statistic indicated stronger differentiation in AJCC 7 curves compared to AJCC 6 (166.128 vs 185.523 overall). Cox likelihood ratio (162.957 vs. 173.951 overall) and AIC (4,831.011 vs 4,820.016 overall) indicated better model fit to the survival data for AJCC 7 versus AJCC 6, overall and for induction subgroups (data not shown). As stage group increases, stronger linear trends for survival were observed at 24, 36 and 60 months using AJCC7 stage groupings, overall and for induction subgroups, compared to AJCC 6. Conclusions: AJCC 7 stage groupings demonstrate superior homogeneity, discriminatory ability and monotonicity compared to AJCC 6. Incorporating the extent of nodal disease, and tumor grade into the revised AJCC 7 stage classification improves prognostic stratification of surgically resected esophagogastric adenocarcinoma patients, including patients who received induction therapy.

Objective In advanced maxillary sinus cancers treated with surgery and radiotherapy, poor local control rates and the potential for organ preservation have prompted interest in the use of systemic therapy. Our objective was to present outcomes for induction compared to adjuvant chemotherapy in the maxillary sinus. Study Design Secondary database analysis. Setting National Cancer Database (NCDB). Subjects and Methods In total, 218 cases of squamous cell maxillary sinus cancer treated with surgery, radiation, and chemotherapy between 2004 and 2012 were identified from the NCDB and stratified into induction chemotherapy and adjuvant chemotherapy cohorts. Univariate Kaplan-Meier analyses were compared by log-rank test, and multivariate Cox regression was performed to evaluate overall survival when adjusting for other prognostic factors. Propensity score matching was also used for further comparison. Results Twenty-three patients received induction chemotherapy (10.6%) and 195 adjuvant chemotherapy (89.4%). The log-rank test comparing induction to adjuvant chemotherapy was not significant ( P = .076). In multivariate Cox regression when adjusting for age, sex, race, comorbidity, grade, insurance, and T/N stage, there was a significant mortality hazard ratio of 2.305 for adjuvant relative to induction chemotherapy (confidence interval, 1.076-4.937; P = .032). Conclusion Induction chemotherapy was associated with improved overall survival in comparison to adjuvant chemotherapy in a relatively small cohort of patients (in whom treatment choice cannot be characterized), suggesting that this question warrants further investigation in a controlled clinical trial before any recommendations are made.

Abstract Purpose No consensus exists regarding the most appropriate staging system to predict overall survival (OS) for hepatocellular carcinoma (HCC) in surgical candidates. Thus, we aimed to determine the prognostic ability of eight different staging systems in a European cohort of patients undergoing liver resection for HCC. Methods Patients resected for HCC between 2010 and 2019 at our institution were analyzed with Kaplan-Meier and Cox regression analyses. Likelihood ratio (LR) χ2 (homogeneity), linear trend (LT) χ2 (discriminatory ability), and Akaike Information Criterion (AIC, explanatory ability) were used to determine the staging system with the best overall prognostic performance. Results Liver resection for HCC was performed in 160 patients. Median OS was 39 months (95% confidence interval (CI): 32–46 months) and median RFS was 26 months (95% CI: 16–34 months). All staging systems (BCLC, HKLC, Okuda, CLIP, ITA.LI.CA staging and score, MESH, and GRETCH) showed significant discriminatory ability regarding OS, with ITA.LI.CA score (LR χ2 30.08, LT χ2 13.90, AIC 455.27) and CLIP (LR χ2 28.65, LT χ2 18.95, AIC 460.07) being the best performing staging systems. Conclusions ITA.LI.CA and CLIP are the most suitable staging system to predict OS in European HCC patients scheduled for curative-intent surgery.

Introduction: Though the incidence of cervical squamous cell cancer (SCC) has reduced during recent years, the amount of cervical adenocarcinoma (AC) has propagated. There is a controversy over whether prognosis is better in SCC or AC. Similar studies have not been conducted in Iran. Material and methods: This is a descriptive-analytic study that is based on historical cohort method. In this retrospective work, all cases of cancer patients were studied from 2004 to 2015 and the medical records of all women recognized with cervical SCC and AC treated in Shahid Sadoughi teaching hospital and Shahid Ramesanzadeh Radiotherapy Center were recovered. In these patients, the epidemiologic characteristics, survival and the factors affecting the survival were investigated. Statistical analysis included frequency table and Chi-Square test. Patient survival was assessed using Kaplan- Meier assessments, and multivariate analysis was done by the Cox regression mode. Results: This study was done on 158 patients identified with cervical carcinoma. Their mean age at the time of diagnosis was 53.3987±1.02150 years. According to histopathologic types, 132 of the patients were classified as SCC with mean age of 52.4840±1.10612 years; while 26 patients were identified as AC with mean age of 58.0385±2.49830 years. The overall survival was 96.338±4.434 months (95% confidence interval) and it was 100.459±4.342 and 54.475±5.334 months for SCC and AC respectively. In the early and advanced stages, overall survival of patients with SCC was different (p=0.001). It was true about the patients with AC (p=0.002). Conclusion: The results of the current study showed the prognosis is worse in patients with cervical AC than cervical SCC

Aim: To evaluate demographics, treatment patterns, radiotherapy utilization and patient outcomes in meningeal melanocytomas. Materials & methods: The National Cancer Database was queried for meningeal melanocytomas diagnosed in 2002–2016. The effects of demographic, clinical and treatment variables were determined via Kaplan–Meier log-rank and Cox regression analyses. Results: The median and 5-year overall survival were 57.46 months and 48%, respectively. Patients earning ≥ $48K showed improved survival (p = 0.0319). Radiotherapy and chemotherapy were utilized in 37.7 and 9% of patients, respectively. Conclusion: Income significantly affected survival. Surgery remains the mainstay approach. Radiotherapy was delivered in more than one-third of patients but did not impact survival. However, further analyses were limited by poor treatment modality information in the database.

Objective The objective of this study was to analyze national trends in human papillomavirus (HPV) testing for patients diagnosed with sinonasal squamous cell carcinoma (SNSCC). Study Design Retrospective database study. Setting National Cancer Database (2010-2016). Methods Cases from 2010 to 2016 with a primary SNSCC diagnosis and known HPV testing status were extracted from the National Cancer Database. Univariate and multivariate analyses were then performed to assess differences in socioeconomic, hospital, and tumor characteristics between tested and nontested patients. Results A total of 2308 SNSCC cases were collected, with 1210 (52.4%) HPV tested and 1098 (47.6%) not tested. On univariate analyses, patient age, insurance, income quartile, population density, treatment facility location, and tumor grade were significantly associated with HPV testing status. After multivariate logistic regression modeling, living in a suburban area had lower odds of HPV testing as compared with living in urban areas (odds ratio, 0.74 [95% CI, 0.55-0.99]; P = .041), while tumor grade III/IV had higher odds than grade I (odds ratio, 1.73 [95% CI, 1.29-2.33]; P < .001). HPV-tested patients had a similar 5-year overall survival to nontested patients (48.3% vs 45.3%, log-rank P = .405). A sharp increase in HPV testing rates was observed after 2010 ( P < .001). Conclusion Among patients with SNSCC, those with high-grade tumors were more likely to be tested for HPV, while patients with a suburban area of residence were less likely. Additionally, there was no significant survival benefit to HPV testing, with tested and nontested groups having similar overall survival. Level of evidence 4.

Introduction: Coxsackievirus/adenovirus receptors (CARs) and desmoglein-2 (DSG2) are similar molecules to adenovirus-based vectors in the cell membrane. They have been found to be associated with lung epithelial cell tumorigenesis and can be useful markers in predicting survival outcome in lung adenocarcinoma (LUAD). Methods: A gene ontology enrichment analysis disclosed that DSG2 was highly correlated with CAR. Survival analysis was then performed on 262 samples from the Cancer Genome Atlas, forming “Stage 1A” or “Stage 1B”. We therefore analyzed a tissue microarray (TMA) comprised of 108 lung samples and an immunohistochemical assay. Computer counting software was used to calculate the H-score of the immune intensity. Cox regression and Kaplan–Meier analyses were used to determine the prognostic value. Results: CAR and DSG2 genes are highly co-expressed in early stage LUAD and associated with significantly poorer survival (p = 0.0046). TMA also showed that CAR/DSG2 expressions were altered in lung cancer tissue. CAR in the TMA was correlated with proliferation, apoptosis, and epithelial–mesenchymal transition (EMT), while DSG2 was associated with proliferation only. The Kaplan–Meier survival analysis revealed that CAR, DSG2, or a co-expression of CAR/DSG2 was associated with poorer overall survival. Conclusions: The co-expression of CAR/DSG2 predicted a worse overall survival in LUAD. CAR combined with DSG2 expression can predict prognosis.

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.

End Results

Adrenal neuroblastoma (NB) is a relatively common malignancy in children. The Surveillance, Epidemiology, and End Results database was used to present demographic data and a survival analysis with the aim of making tumor management better. The Surveillance, Epidemiology, and End Results database was used to search pediatric patients (age £16 years) with NB from 2004 to 2013. The Kaplan-Meier method was used to calculate the overall survival. And, we used Cox regression analysis to determine hazard ratios for prognostic variables. Independent prognostic factors were selected into the nomogram to predict individual's three-, five-, and seven-year overall survival. The study included a total of 1870 pediatric patients with NB in our cohort. Overall, three-, five-, and seven-year survival rates for adrenal NB were 0.777, 0.701, and 0.665, respectively, whereas the rates for nonadrenal NB were 0.891, 0.859, and 0.832, respectively. The multivariate analysis identified age >1 year, no complete resection (CR)/CR, radiation, and regional/distant metastasis as independent predictors of mortality for adrenal NB. Concordance index of the nomogram was 0.665 (95% confidence interval, 0.627–0.703). Pediatric patients with adrenal NB have significantly worse survival than those with nonadrenal NB. Adrenal NB with age <1 year, treated with surgery, no radiation, and localized tumor leads to a better survival. There was no survival difference for patients to receive CR and no CR.
