BackgroundAs ovarian cancer treatment shifts to provide more complex aspects of care at high-volume centers, almost a quarter of patients, many of whom reside in rural counties, will not have access to those centers or receive guideline-based care.ObjectiveTo explore the association between proximity of residential zip code to a high-volume cancer center with mortality and survival for patients with ovarian cancer.MethodsThe National Cancer Database was queried for cases of newly diagnosed ovarian cancer between January 2004 and December 2015. Our predictor of interest was distance traveled for treatment. Our primary outcomes were 30-day mortality, 90-day mortality, and overall survival. The effect of treatment on survival was analyzed with the Kaplan-Meier method. Multiple logistic regression for binary outcomes and Cox proportional hazards regression for overall survival were used to assess the effect of distance on outcome, controlling for potential confounding variables.ResultsA total of 115 540 patients were included. There was no statistically significant difference in 30- or 90-day mortality among any of the travel distance categories. A statistically significant decrease in 30-day re-admission was found among patients who lived further away from the treating facility. A total of 105 529 patients were available for survival analysis, and survival curves significantly differed between distance strata (p<0.0001). The adjusted regression models demonstrated increased long-term mortality in patients who lived farther away from the treating facility after controlling for potential confounding.ConclusionAlthough 30- and 90-day mortality do not differ by travel distance, worse survival is observed among women living >50 miles from a high-volume treatment facility. With a national policy shift toward centralization of complex care, a better understanding of the impact of distance on survival in patients with ovarian cancer is crucial. Our findings inform the practice of healthcare delivery, especially in rural settings.

In this study, we aimed to evaluate the impact of surgical wait time (SWT) on outcomes of patients with renal cell carcinoma (RCC), and to investigate risk factors associated with prolonged SWT. Using the National Cancer Database, we retrospectively reviewed the records of patients with pT3 RCC treated with radical or partial nephrectomy between 2004 and 2014. The cohort was divided based on SWT. The primary out-come was 5-year overall survival (OS). Logistic regression analysis was used to investigate the risk factors associated with delayed surgery. Cox proportional hazards models were fitted to assess relations between SWT and 5-year OS after adjusting for confounding factors. A total of 22,653 patients were included in the analysis. Patients with SWT > 10 weeks had higher occurrence of upstaging. Using logistic regression, we found that female patients, African-American or Spanish origin patients, treatment in academic or integrated network cancer center, lack of insurance, median household income of <$38,000, and the Charlson–Deyo score of ≥1 were more likely to have prolonged SWT. SWT > 10 weeks was associated with decreased 5-year OS (hazard ratio [HR], 1.24; 95% confidence interval [CI], 1.15–1.33). This risk was not markedly attenuated after adjusting for confounding variables, including age, gender, race, insurance status, Charlson–Deyo score, tumor size, and surgical margin status (adjusted HR, 1.13; 95% CI, 1.04–1.24). In conclusion, the vast majority of patients underwent surgery within 10 weeks. There is a statistically significant trend of increasing SWT over the study period. SWT > 10 weeks is associated with decreased 5-year OS.

IntroductionDelays from primary surgery to chemotherapy are associated with worse survival in ovarian cancer, however the impact of delays from neoadjuvant chemotherapy to interval debulking surgery is unknown. We sought to evaluate the association of delays from neoadjuvant chemotherapy to interval debulking with survival.MethodsPatients with a diagnosis of stage III/IV ovarian cancer receiving neoadjuvant chemotherapy from July 2015 to December 2017 were included in our analysis. Delays from neoadjuvant chemotherapy to interval debulking were defined as time from last preoperative carboplatin to interval debulking >6 weeks. Fisher’s exact/Wilcoxon rank sum tests were used to compare clinical characteristics. The Kaplan–Meier method, log-rank test, and multivariate Cox Proportional-Hazards models were used to estimate progression-free and overall survival and examine differences by delay groups, adjusting for covariates.ResultsOf the 224 women, 159 (71%) underwent interval debulking and 34 (21%) of these experienced delays from neoadjuvant chemotherapy to interval debulking. These women were older (median 68 vs 65 years, P=0.05) and received more preoperative chemotherapy cycles (median 6 vs 4, P=0.003). Delays from neoadjuvant chemotherapy to interval debulking were associated with worse overall survival (HR 2.4 95% CI 1.2 to 4.8, P=0.01), however survival was not significantly shortened after adjusting for age, stage, and complete gross resection, HR 1.66 95% CI 0.8 to 3.4, P=0.17. Delays from neoadjuvant chemotherapy to interval debulking were not associated with worse progression-free survival (HR 1.55 95% CI 0.97 to 2.5, P=0.062). Increase in number of preoperative cycles (P=0.005) and lack of complete gross resection (P<0.001) were the only variables predictive of worse progression-free survival.DiscussionDelays from neoadjuvant chemotherapy to interval debulking were not associated with worse overall survival after adjustment for age, stage, and complete gross resection.

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.

756 Background: We sought to assess the impact of LND in non metastatic pT2-3 patients utilizing a large population-based dataset. Methods: The National Cancer Database was queried for patients with cN0pT2-3 RCC that underwent radical nephrectomy (RN) +/- LND from 2004-2015. Descriptive analyses and Multivariable cox regression (MVA) were performed to elucidate factors associated with all-cause mortality (ACM) on a per stage basis (pT2 and pT3 RCC). Kaplan-Meier analyses (KMA) were used to determine the impact of LND on ACM. Results: 43,143 patients were analyzed, 9,491 (22.0%) underwent LND, 6.7% were positive (pN+). MVA demonstrated increasing age (HR 1.04, p<0.001), pN+ (HR 2.90, p<0.001), increasing Charlson score (CCI, HR 2.92, p<0.001), and high grade (HR 1.11, p<0.001), were associated with worsened ACM in pT2. MVA in pT3 revealed increasing age (HR 1.03, p<0.001), pN0 with 0-4 nodes removed (HR 1.24, p<0.001), pN+ (HR 3.06, p<0.001), papillary and non-specific histology (HR 1.17 p=0.002, HR 1.14 p<0.001 respectively), increasing CCI (HR 2.09, p<0.001), high grade (HR1.19, p<0.001), black race (HR 1.12, p=0.028), and increasing tumor size (HR 1.00, p<0.001) were associated with worsened ACM. MVA for increased likelihood of pN+ found high grade (HR1.23, p<0.001), Academic facility and integrated network cancer center (HR 2.13 and 1.17, p<0.001 and p=0.013 respectively), >10cm tumor (HR 1.67 p<0.001), clear cell histology (p<0.001), Caucasian race (p<0.001)and male sex (HR 1.06 P=0.026) were associated. KMA of pT2 patients demonstrates no significant difference in 5-year OS for LND compared to no LND (60.8% vs. 55.9%, p=0.21), and worsened OS for pN+ compared to pN0 and pNx (p<0.001). KMA of pT3 patients showed worsened 5-year OS for patients undergoing LND (p<0.001), and pN+ had worsened OS compared to pN0 and pNx (p<0.001). Conclusions: LND conveyed no ACM benefit in cN0 pT2 or pT3 RCC. pN+ was associated with decreased survival, with risk factors including Caucasian race, clear cell histology, high grade disease, tumors >10cm. LND in patients with cN0pT2-T3 disease may identify higher risk cohorts.

PURPOSE Esophageal squamous cell cancer (ESCC) is still associated with a dismal prognosis. However, surgical series have shown that high-volume hospitals have better outcomes and that the impact of center volume on definitive chemoradiotherapy (dCRT) or CRT plus surgery (CRT + S) remains unknown. METHODS We performed a retrospective analysis of patients with locally advanced stage II-III (non-T4) ESCC treated with dCRT or CRT + S in São Paulo state, Brazil. Descriptive variables were assessed with the χ2 test after categorization of hospital volume (high-volume [HV] center, top 5 higher volume, or low-volume [LV] center). Overall survival (OS) was assessed with Kaplan-Meier curves, log-rank tests, and Cox proportional hazards. Finally, an interaction test between each facility’s treatments was performed. RESULTS Between 2000 and 2013, 1,347 patients were analyzed (77% treated with dCRT and 65.7% in HV centers) with a median follow-up of 23.7 months. The median OS for dCRT was 14.1 months (95% CI, 13.3 to 15.3 months) and for CRT + S, 20.6 months (95% CI, 16.1 to 24.9 months). In the multivariable analysis, dCRT was associated with worse OS (hazard ratio [HR], 1.38; 95% CI, 1.19 to 1.61; P < .001) compared with CRT + S. HV hospitals were associated with better OS (HR, 0.82; 95% CI, 0.71 to 0.94; P = .004) compared with LV hospitals. Importantly, CRT + S superiority was restricted to HV hospitals (dCRT v CRT + S: HR, 1.56; 95% CI, 1.29 to 1.89; P < .001), while in LV hospitals, there was no statistically significant difference (HR, 1.23; 95% CI, 0.88 to 1.43; P = .350), with a significant interaction test ( Pinteraction = .035). CONCLUSION Our data show that CRT + S is superior to dCRT in the treatment of ESCC exclusively in HV hospitals, which favors the literature trend to centralize the treatment of ESCC in HV centers.

Objective To determine whether treatment of sinonasal squamous cell carcinoma (SCC) at a high-volume facility affects survival. Study Design Retrospective database analysis. Setting National Cancer Database (2004-2014). Subjects and Methods The National Cancer Database was queried for sinonasal SCC from 2004 to 2014. Patient demographics, tumor characteristics and classification, resection margins, treatment regimen, and facility case-specific volume—averaged per year and grouped in tertiles as low (0%-33%), medium (34%-66%), and high (67%-100%)—were compared. Overall survival was compared with Cox proportional hazards regression analysis. Results A total of 3835 patients treated for sinonasal SCC between 2004 and 2014 were identified. Therapeutic options included surgery alone (18.6%), radiotherapy (RT) alone (29.1%), definitive chemoradiation (15.4%), surgery with adjuvant RT (22.8%), and combinations (14.1%) of the aforementioned treatments. Patients who underwent surgery with adjuvant RT had better overall survival (hazard ratio [HR], 0.74; P < .001; 95% CI, 0.63-0.86). As for treatment volume per facility, 7.4% of patients were treated at a low-volume center, 17.5% at a medium-volume center, and 75.1% at a high-volume center. Univariate analysis showed that treatment at a high-volume facility conferred a significantly better overall survival (HR, 0.77; P = .002). Multivariable Cox proportional hazards regression analysis, adjusting for age, sex, tumor classification, and treatment regimen, demonstrated that patients who underwent treatment at a high-volume facility (HR, 0.81; P < .001) had significantly improved survival. Conclusion This study shows a better overall survival for sinonasal SCC treated at high-volume centers. Further study may be needed to understand the effect of case volume on the paradigms of sinonasal SCC management.

ObjectivesThe aim of this study was to investigate the impact of body mass index (BMI) on completion, complications, and clinical outcomes of intraperitoneal (IP) chemotherapy in patients with advanced-stage ovarian cancer.MethodsPatients with optimally cytoreduced International Federation of Gynecology and Obstetrics stage IIIC ovarian cancer treated with IP chemotherapy were retrospectively identified using an institutional review board–approved database. Clinical data were abstracted from the longitudinal medical record. Survival estimates were calculated using the Kaplan-Meier method.ResultsNinety-two patients (35.5%) completed at least one cycle of IP chemotherapy. For these patients, there was no difference in histology, surgical complexity, or degree of cytoreduction based on BMI. Sixty-five percent of normal weight, 70% of overweight, and 59.1% of obese women completed 6 cycles (P= 0.697). There was also no significant difference in IP chemotherapy complications (P= 0.303). Body mass index had no impact on disease-free survival (P= 0.44) or overall survival, with a median overall survival of 68.5 months for normal weight, 65.9 months for overweight, and 61.7 months for obese women (P= 0.25). However, on multivariate analysis, obesity had an odds ratio of 2.92 (P= 0.02) for mortality. There was a trend toward treatment with intravenous chemotherapy (84.2%) over IP (15.8%) in patients with class II obesity (P= 0.06).DiscussionThere was no difference in completion of IP chemotherapy or complications with respect to BMI; however, there was a trend away from treatment with IP therapy in extreme obesity. These data suggest that IP chemotherapy is feasible in obese patients without incurring increased morbidity.

303 Background: BTCs include intrahepatic (IHC), hilar, distal bile duct (DBD), and gallbladder carcinoma (GBC). Statins, aspirin and metformin may have antineoplastic properties. The impact of their use on overall survival and the recurrence free survival of patients who had curative resection of BTC has not been evaluated. Methods: Baseline demographics and use of statins, aspirin or metformin at diagnosis were evaluated in 913 patients with BTC from 01/87 - 07/13 treated at Princess Margaret Cancer Center, Toronto. Their prognostic significance for recurrence free and overall survival was determined using a Cox proportional hazards model. Results: The median age at diagnosis for the entire cohort was 65.7 years (range 23.7-93.7). 795 patients had a performance status < 2 and 461 (50.5%) were male. The primary site was GBC in 310 (34%) patients, DBD in 212 (23%), IHC in 200 (22%) and hilar in 191 (21%). Curative surgical resection was performed in 355 (39%) patients. Among the entire cohort of 913 patients, 151 (16.5%) reported statin use at diagnosis. Atorvastatin was the statin used in 55% of patients. 146 (16%) reported aspirin use and 81 (9%) reported metformin use at diagnosis. Age (p=0.05, p<0.01), and stage (p<0.001, p<0.001) were prognostic on multivariable analysis for recurrence free and overall survival respectively. GBC (p=0.01), DBD (p<0.01) primary and performance status ≥ 2 (p < 0.0001) were also prognostic for overall survival. Recurrence free and overall survival among statin users and nonusers was similar (Hazard Ratio (HR) 1.07, 95% confidence interval (CI) 0.78-1.48, p=0.68) and (HR 0.84 (95% CI 0.67-1.05, p=0.12) respectively. Recurrence free and overall survival among aspirin users and nonusers was similar (HR 0.91, 95% CI 0.64-1.29, P=0.58) and (HR 0.98 (95% CI 0.80-1.22, P=0.88) respectively. Recurrence free and overall survival among metformin users and nonusers was also similar (HR 0.71, 95% CI 0.43-1.17, p=0.18) and (HR 0.81 (95% CI 0.60-1.08, p=0.14) respectively. Conclusions: In this large retrospective cohort of BTC patients, statin, aspirin or metformin use was not associated with improved recurrence free or overall survival.
