Abstract BackgroundIncreasing evidence indicates that the pathology and the modified Kadish system have some influence on the prognosis of esthesioneuroblastoma (ENB). However, an accurate system to combine pathology with a modified Kadish system has not been established.MethodsThis study aimed to set up and evaluate a model to predict overall survival (OS) accurately in ENB, including clinical characteristics, treatment and pathological variables. We screened the information of patients with ENB between January 1, 1976, and December 30, 2012 from the National Cancer Institute Surveillance, Epidemiology, and End Results (SEER) program as a training cohort. The validation cohort consisted of patients with ENB at Sun Yat-sen University Cancer Center and The First Affiliated Hospital of Sun Yat-sen University in the same period, and 87 patients were identified. The Pearson’s chi-squared test was used to assess significance of clinicopathological and demographic characteristics. We used the Cox proportional hazards model to examine univariate and multivariate analyses. The model coefficients were used to calculate the Hazard ratios (HR) with 95% confidence intervals (CI). Prognostic factors with a p-value < 0.05 in multivariate analysis were included in the nomogram. The concordance index (c-index) and calibration curve were used to evaluate the predictive power of the nomogram.ResultsThe c-index of training cohort and validation cohort are 0.737 (95% CI, 0.709 to 0.765) and 0.791 (95% CI, 0.767 to 0.815) respectively. The calibration curves revealed a good agreement between the nomogram prediction and actual observation regarding the probability of 3-year and 5-year survival. We used a nomogram to calculate the 3-year and 5-year growth probability and stratified patients into three risk groups.ConclusionsThe nomogram provided the risk group information and identified mortality risk and can serve as a reference for designing a reasonable follow-up plan.# Co-first authors: Lijie Jiang and Tengjiao Lin contributed equally to this article.

Abstract Background Thymoma is an uncommon intrathoracic malignant tumor and has a long natural history. It is uncertain whether the survival of thymoma patient is affected by prior cancer history. Finding out the impact of a prior cancer history on thymoma survival has important implications for both decision making and research. Method The Surveillance, Epidemiology, and End Results (SEER) database was queried for thymoma patients diagnosed between 1975 and 2015. Kaplan-Meier methods and Cox proportional hazards model were used to analyze overall survival across a variety of stages, age, and treatment methods with a prior cancer history or not. Results A total of 3604 patients with thymoma were identified including 507 (14.1%) with a prior cancer history. The 10-year survival rate of patients with a prior cancer history (53.8%) was worse than those without a prior cancer history (40.32%, 95%CI 35.24-45.33, P < 0.0001). However, adjusted analyses showed that the impact of a prior cancer history was heterogenous across age and treatment methods. In subset analyses, prior cancer history was associated with worse survival among patients who were treated with chemoradiotherapy (HR: 2.80, 95% CI: 1.51-5.20, P = 0.001) and age ≤ 65 years (HR: 1.33, 95%CI: 1.02-1.73, P = 0.036). Conclusions Prior cancer history provides an inferior overall survival for patients with thymoma. But it does not worsen the survival in some subgroups and these thymoma patients should not be excluded from clinical trials.

The outcomes of multimodality treatment of 227 glioblastoma (grade IV) patients were evaluated in relation to the postoperative chemoradiotherapy (ChRT) regimen. No statistically significant differences were found in groups with conventional ChRT (temozolomide 75 mg/m2 per os 1 hour before the radiation treatment during the whole course of radiotherapy, n=111) and modified ChRT (temozolomide 75 mg/m2 per os 5 days a week 1 hour before the radiation treatment in the first and last two weeks of radiotherapy, n=116), the median overall survival being 16 months and 16 months respectively (P=0,889). The Cox proportional hazards model demonstrated that the postoperative ChRT regimen was not a prognostic factor affecting patient survival.

5042 Background: Sunitinib demonstrated superior progression-free survival (PFS; the primary endpoint) over interferon-alfa (IFN-α) as first-line mRCC therapy (NEJM 2007;356:115). Median overall survival (OS) with sunitinib compared to IFN-α was: 26.4 vs. 21.8 months (HR=0.821; P=0.051 by unstratified log-rank test; Proc ASCO 2008;26, May 20 suppl; abstr 5024). An analysis of prognostic factors for OS was performed on data from this trial. Methods: 750 treatment-naïve mRCC patients were randomized 1:1 to receive sunitinib or IFN-α. By Cox proportional hazards model, selected pretreatment variables were evaluated univariately and in a multivariate model for each treatment arm. Multivariate models for each treatment arm were based on a stepwise algorithm with a type I error of 0.25 for entry and 0.15 for elimination. Further elimination was applied to identify variables significant at P<0.05. Results: In multivariate analysis of sunitinib patients, factors associated with longer OS include: interval from diagnosis to treatment ≥1 yr, ECOG PS of 0, lower corrected calcium, absence of bone metastases, lower lactic dehydrogenase (LDH), and higher hemoglobin (Hgb) ( table ). For the IFN-α treatment arm, male gender, absence of bone or lymph node metastases, lower LDH, higher Hgb, lower corrected calcium, higher neutrophil count, and interval from diagnosis to treatment ≥1 yr were associated with longer OS. Conclusions: For patients in the sunitinib treatment arm, prognostic factors identified were similar to the factors previously identified in the MSKCC risk groups (J Clin Oncol 2002;20:289). Additional prognostic factors were identified for the IFN-α arm. Further studies are warranted to independently validate these findings as well as to identify tumor-specific prognostic factors.

e15517 Background: Recent reports suggest that estrogen mediated inhibition of IL-6 protects against the development of HCC and may explain the decreased risk of liver cancer in women. We investigated the relation-hip between gender, age, and survival for patients with localized HCC. Methods: We identified 11,097 patients with localized, histologically defined HCC, from 1988- 2003, using the Surveillance, Epidemiology, and End Results (SEER) registry. Age at diagnosis, sex, ethnicity, and overall survival were evaluated using Cox proportional hazards model. The models were adjusted for treatment modality, tumor differentiation, tumor size, lymph node involvement, and number of lesions; they were stratified by year of diagnosis and SEER registry site. Results: 8,111 (73%) patients were men and 2,986 (27%) were women. In univariate and multivariate analyses, female gender, young age (< 55 yo), and Asian ethnicity were all associated with improved overall survival (p<0.001). In patients less than 55 yo, women had a superior OS and cancer specific survival (CSS) when compared to men (OS: 18 months vs. 9, CSS: 31 months vs. 14, p<0.001). Conversely, in patients older than 55, there were no gender differences (OS: 8 months vs. 8, CSS 13 months vs. 11, p = 0.08). Local therapies, including, ablation (HR = 0.47 [0.43–0.53]), hepatectomy (HR = 0.40 [0.36–0.44]), radiation (HR = 0.67 [0.57–0.78]) and transplantation (HR = 0.17 [0.15–0.20]) were also associated with improved survival. There were no interactions identified between gender and treatment use. Conclusions: To our knowledge, this is the first report to highlight the superior outcome of premenopausal women with HCC compared to men. We postulate a potential role for estrogen in influencing the biology of HCC and the response to treatment. These observations are consistent with ones made in other gastrointestinal cancers and with reported preclinical data suggesting a protective role for estrogen. Further studies that confirm these observations and elucidate the biology of estrogen's influence on HCC are needed. [Table: see text] No significant financial relationships to disclose.

The Impact

528 Background: The standard treatment for locally advanced rectal cancer is neoadjuvant chemoradiation followed by surgery, but many physicians question the benefit of multimodality therapy in patients with stage T3N0M0 disease. We aimed to determine the impact of radiation therapy (RT) on overall survival (OS) in this group of patients. Methods: We used the Surveillance, Epidemiology, and End Results database to identify patients undergoing surgery for T3N0M0 adenocarcinoma of the rectum from 2004 to 2010. The Kaplan-Meier method was used to compare OS for patients receiving RT vs. no RT, along with for pre-op vs. post-op RT among patients that received RT. Multivariable analysis (MVA) using a Cox proportional hazards model was performed to assess the association of RT with OS after adjusting for patient age, gender, race, tumor grade, carcinoembryonic antigen, type of surgery, and circumferential margin status. The analysis was repeated separately on patients that underwent total colectomy (TC) vs. sphincter-sparing surgery. Results: The cohort included 8,679 patients, including 4,705 who received RT and 3,974 who did not. Median age was 66 years. Five year OS was 76.5% in patients who received RT, compared to 60.0% in patients who did not receive RT (p <0.001). Five year OS was 76.9% for patients receiving pre-op RT vs. 75.7% in patients receiving post-op RT (p = 0.247). In patients undergoing TC, five year OS was 74.7% for patients receiving RT, compared to 47.5% in patients not receiving RT (p <0.001). In patients undergoing sphincter-sparing surgery, five year OS was 77.7% in patients receiving RT, compared to 62.9% in patients not receiving RT (p <0.001). Use of RT was significantly associated with OS on MVA, both in the entire cohort (HR 0.70 [95% CI 0.60-0.81]; p<0.001) and in subsets of patients undergoing TC (HR 0.55 [95% CI 0.38-0.79]; p=0.001) and sphincter-sparing surgery (HR 0.70 [95% CI 0.59-0.84]; p<0.001). Conclusions: The use of RT is associated with superior OS in patients undergoing surgery for T3N0M0 adenocarcinoma of the rectum. This benefit is demonstrated in both the pre-op and post-op settings and applies to patients undergoing both TC and sphincter-sparing surgery.

e16558 Background: Cyclooxygenase (COX) inhibition is postulated to restore the immune environment and synergizes with immune checkpoint inhibitors (ICI). The concurrent use of COX inhibitors (COXi) and ICI was associated with longer disease control in metastatic melanoma and non-small cell lung cancer. However, its role in mRCC remains unclear. Methods: We retrospectively reviewed 194 patients with mRCC treated with ICI (PD-(L)1 inhibitors +/- CTLA-4 inhibitors or TKIs) at Moffitt Cancer Center between 6/2014-7/2019. Concurrent use of COXi (aspirin [ASA] or NSAIDs) was defined as at least 3 weeks of COXi use during the first ICI course. Clinical characteristics of both arms were compared using Chi-squared or Kruskal-Wallis Rank Sum test. Time to progression (TTP) and Overall survival (OS) were compared using Kaplan Meier’s estimates. Univariate and multivariate Cox proportional hazards model was performed to evaluate the association between clinical factors, TTP, and OS. Results: Of 194 patients, 126 patients (64.9%) took COXi. Median age was 59.7 years and 80.4% were male. COXi arm had fewer patients with < 1 year from diagnosis to systemic treatment (45.9% vs 69.5%, p = 0.006) and more advanced age (median: 66 years vs 60 years, p = 0.01). IDMC risk group, number of prior therapies, neutrophil to lymphocytes ratio were similar between both arms. Median TTP was 8 months (m) for COXi arm and 12m for ICI only (HR 1.38; 95% CI [0.98, 1.94]). Median OS was 27m for COXi arm and 33m for ICI only (HR 1.05, 95% CI [0.69, 1.59]). Early mortality rate (within 3m of ICI treatments) were similar between both arms. Conclusions: In contrast to melanoma and lung cancer, concurrent use of COXi and ICI did not improve TTP and OS in patients with mRCC. The dual blockade showed a trend for shorter TTP. Further validation studies with larger cohorts are needed to confirm this finding.[Table: see text]
