378 Background: Testicular seminoma is the most common solid tumor seen in patients aged 15-35 and disease specific survival approaches 100% in controlled studies, even for those with node-positive disease. We sought to describe modern practice patterns as well as survival outcomes and factors associated with receipt of adjuvant therapy for patients presenting with initial clinical stage (CS) IIA/B disease. Methods: Data on patients diagnosed with CS IIA/B testicular seminoma from 1998-2011 were extracted from the National Cancer Data Base. Demographic, clinical, treatment, payer characteristics were evaluated using multivariate logistic regression to identify factors associated with receipt of chemotherapy or adjuvant radiation therapy (ART) within 6 months of orchiectomy. Five-year Kaplan-Meier overall survival (OS) by CS and treatment was calculated. Results: In total, 2,185 patients with CS II A/B were included. Management included orchiectomy alone (11.35%), adjuvant chemotherapy (27.46%), or ART (52.72%). In multivariate analysis, receipt of orchiectomy plus ART rather than adjuvant chemotherapy was more likely with CS IIA status (OR 2.4, p < 0.01), treatment outside of teaching or NCI network institution (OR 1.9-2.8, p < 0.02), or tumor size ≥4cm (OR 1.6, p < 0.01). Receipt of ART was less likely in Hispanic patients (OR 0.6, p=0.03) or in those diagnosed from 2006-2011 (OR 0.5, p < 0.01). Five-year OS for all patients was 97.2% for orchiectomy + ART, and 93.9% for orchiectomy + chemotherapy (log-rank p = 0.01). For CS IIA patients, 5-year OS was 98.3% for orchiectomy + ART versus 93.6% for orchiectomy + chemotherapy (log-rank p < 0.01). Differences in OS for CS IIB treated with chemotherapy or ART were not statistically significant. Conclusions: Consistent with national guideline recommendations, our analysis suggest that compared to chemotherapy, ART is associated with a survival advantage for CS IIA patients. Chemotherapy or ART showed no significant difference in effectiveness in patients with CS IIB. Disease bulk, race, treatment center type, and time period are associated with choice of adjuvant therapy. Longer follow-up and validation of these results is needed to account for late effects of treatment.

e19022 Background: There has been some improvement in overall survival (OS) for patients with MCL over the past years [Gordon 2014]. However, side effects of treatment remain a major concern. With introduction of novel therapies like IT, it is imperative to optimize treatment regimens to improve survival while minimizing toxicity. Methods: MCL patients (pts) who were diagnosed in 2013 or later with information available about chemotherapy (CT) and IT and did not receive transplant were extracted from NCDB. Pts were assigned to age categories and were sorted into six groups based on different combinations of CT (none, single agent (SA), and multi-agent (MA)) with or without IT. Cox regression analysis was used to perform multivariate analysis that included age category, sex, race, clinical stage, Charlson/Deyo score, CT, radiation, and IT for each group. Multivariate p values (p) were used to analyze statistical significance. Kaplan Meier method was utilized to analyze OS. T-test was used to compare means (t-p). Results: 1438 total pts were identified with a mean age of 70 (range 24-90); 71% male; 93% white, 4% black, 3% others; 42% with stage III/IV disease. 667 pts did not receive CT or IT, and 40 received IT alone and both of these groups were excluded from further analysis. 52 pts received SA- (without) IT, 206 received SA+(with) IT and 260 pts received MA-IT and 213 MA+IT. Mean age was 72 and 66 for SA and MA groups, respectively (t-p<0.01). Mean OS for SA+IT was 27 months (m) vs SA-IT 16 m (p < 0.01). MA+IT v MA-IT showed no difference in mean OS (25 vs 26 m, respectively, p =0.49). Although there was a significant difference in OS between SA and MA groups without IT (16 vs 25 months, p < 0.01). SA + IT group showed comparable mean OS time to MA + IT (27 vs 26 m, p =0.145). Conclusions: For MCL pts, MA has superior OS to SA group. However, adding IT significantly improves OS for SA group and makes it comparable to MA. Adding IT to MA did not provide significant difference in OS. These results highlight the possibility of achieving same OS with less toxic regimens. Hence further evaluation in a prospective study to optimize treatment while reducing toxicity is warranted.

388 Background: Seminoma is the most common testicular cancer, and cancer specific survival approaches 100% if diagnosed and treated early. Following orchiectomy, several adjuvant therapy options exist for patients with stage 1A/B and 2A/B disease. As the Affordable Care Act’s (ACA) individual insurance mandate and expansion of Medicaid coverage will begin in 2014, we sought to understand whether differences exist in receipt of adjuvant therapy between uninsured and Medicaid patients in order to predict possible treatment patterns after the ACA takes effect. Methods: Uninsured and Medicaid patients diagnosed with seminoma from 1998-2010 in the National Cancer Data Base were identified. Multivariate logistic regressions were used to assess the relationship between uninsured status vs. Medicaid and receipt of adjuvant therapy. Results: Of 41,745 seminoma patients, 5,895 (14%) patients were on Medicaid or uninsured. Compared to Medicaid patients, uninsured patients were more likely to be younger (<29 years old), Hispanic, live in the South, treated in community hospitals, reside in areas with higher education levels, and present with stage IA/B disease (66.5% vs 59.4%, p < 0.01). After controlling for sociodemographic and clinical characteristics, uninsured stage IA/B patients had a 16% decreased likelihood of receiving adjuvant radiation or chemotherapy than Medicaid patients (p<0.05). In addition, stage 1A/B patients who were Hispanic, aged 50 or more, diagnosed in 2006-2010, treated in low-volume-case facilities or had tumor size < 4cm were less likely to receive adjuvant therapy. No treatment differences by insurance were seen in stage IIA/B patients. Conclusions: Our analysis suggests a modest association between the decision to seek optional adjuvant therapy and uninsured vs. Medicaid status in patients with stage IA/B seminoma. Given that national recommendations support surveillance, it will be increasingly important to counsel newly insured patients on the benefits of post-orchiectomy surveillance for early stage disease. In addition, no difference in management was identified for CS 2A/B patients suggesting that required therapy was not modified or avoided in the uninsured.

e15669 Background: There is a paucity of data and no consensus regarding administration of adjuvant therapy after resection of gallbladder cancer. In the absence of a completed clinical trial, we retrospectively reviewed US cancer data. Methods: National Cancer Data Base was queried for patients diagnosed with gallbladder adenocarcinoma between 2004-2014 who underwent definitive resection for non-metastatic disease (pT1b, pT2, pT3, pN0, pN1, pNX) and had R0 and R1 resection margins. One-to-one propensity score matching was used to account for potential selection bias in patient and tumor characteristics. Kaplan-Meier method was used to compare overall survival. Results: Of 4830 patients identified, 1489 (30.8%) received adjuvant chemotherapy. Patients who received adjuvant chemotherapy were more likely to be younger, have private insurance or Medicare, have no comorbidities, higher T stage, and moderately to poorly differentiated tumors (all p-values < 0.0001). The majority of patients who received adjuvant chemotherapy also received adjuvant radiation (58.0%). On unadjusted analysis, patients who received adjuvant chemotherapy had no difference in median overall survival compared to those who did not (25.8 vs 29.0 mo; p = 0.3060). After matching for sex, age, race, insurance, comorbidity, facility type, pT stage, lymph node status, resection margins (R0 vs R1), adjuvant radiation, and tumor grade no difference in median overall survival remained between patients who did (21.8 mo) and did not (22.6 mo) receive adjuvant chemo (p = 0.6843). However, after matching on the propensity to receive adjuvant radiation in addition to the above covariates, receipt of adjuvant radiation resulted in a persistently significant increase in median overall survival (27.8 vs 22.2 mo; p = 0.0005). Conclusions: After matching for potential confounders, there is no difference in overall survival for patients who did and did not receive adjuvant chemotherapy after R0/R1 resection for pT1b, pT2, and pT3 gallbladder adenocarcinoma; however, adjuvant radiation does appear to confer a survival advantage. These results support the current treatment guidelines until evidence from RCTs becomes available.

A systematic review and meta analysis has been undertaken in order to evaluate the effectiveness of adjuvant therapy following surgery for early ovarian cancer. Trials reported since 1990 have been of a higher quality enabling a meta analysis of adjuvant chemotherapy vs adjuvant radiotherapy and a meta analysis of adjuvant chemotherapy vs observation. There was no significant difference between radiotherapy and chemotherapy, though these comprised studies which demonstrated considerable heterogeneity. Chemotherapy did confer significant benefit over observation in terms of both overall and disease free survival. Except for women in whom adequate surgical staging has revealed well differentiated disease confined to one or both ovaries with intact capsule, platinum chemotherapy should be offered to reduce risk of recurrence.

Background Multidisciplinary treatment (MDT) and adjuvant therapy are associated with improved survival rates in breast cancer. However, nonadherence to MDT decisions is common in patients. We developed a smartphone-based app that can facilitate the full-course management of patients after surgery. Objective This study aims to investigate the influence factors of treatment nonadherence and to determine whether this smartphone-based app can improve the compliance rate with MDTs. Methods Patients who had received a diagnosis of invasive breast cancer and had undergone MDT between March 2013 and May 2019 were included. Patients were classified into 3 groups: Pre-App cohort (November 2017, before the launch of the app); App nonused, cohort (after November 2017 but not using the app); and App used cohort (after November 2017 and using the app). Univariate and multivariate analyses were performed to identify the factors related to MDT adherence. Compliance with specific adjuvant treatments, including chemotherapy, radiotherapy, endocrine therapy, and targeted therapy, was also evaluated. Results A total of 4475 patients were included, with Pre-App, App nonused, and App used cohorts comprising 2966 (66.28%), 861 (19.24%), and 648 (14.48%) patients, respectively. Overall, 15.53% (695/4475) patients did not receive MDT recommendations; the noncompliance rate ranged from 27.4% (75/273) in 2013 to 8.8% (44/500) in 2019. Multivariate analysis demonstrated that app use was independently associated with adherence to adjuvant treatment. Compared with the patients in the Pre-App cohort, patients in the App used cohort were less likely to deviate from MDT recommendations (odds ratio [OR] 0.61, 95% CI 0.43-0.87; P=.007); no significant difference was found in the App nonused cohort (P=.77). Moreover, app use decreased the noncompliance rate for adjuvant chemotherapy (OR 0.41, 95% CI 0.27-0.65; P<.001) and radiotherapy (OR 0.49, 95% CI 0.25-0.96; P=.04), but not for anti-HER2 therapy (P=.76) or endocrine therapy (P=.39). Conclusions This smartphone-based app can increase MDT adherence in patients undergoing adjuvant therapy; this was more obvious for adjuvant chemotherapy and radiotherapy.

406 Background: To assess contemporary treatment patterns and survival for stage IS testicular cancer. Methods: Using the National Cancer Data Base, we identified 1,362 patients with AJCC stage IS testicular cancer (seminoma or non-seminoma) treated between 2004-2012 with either adjuvant therapy (AT) or initial surveillance. AT was defined as the receipt of chemotherapy, radiotherapy (RT), or retroperitoneal lymph node dissection (RPLND) as part of first line treatment after orchiectomy. Annual percent change (APC) in the use of AT was calculated and multivariable logistic regression analysis was performed to identify predictors of receiving AT. Inverse probability of treatment weighting (IPTW)-adjusted Kaplan-Meier curves and Cox regression analyses were used to compare overall survival (OS) between AT and initial surveillance groups. All analyses were stratified according to histologic type. Results: Overall, there were 581 (43%) and 781 (57%) men with seminoma and non-seminoma, respectively. Among men with seminoma, 61% received AT (RT = 45%, chemo = 16%) while 39% received initial surveillance. The use of AT decreased over the study period (APC = -2.7; 95%CI: -4.4, 1.1; P = 0.001). Predictors of receiving AT included low income (OR = 1.63; 95%CI: 1.03, 2.56; P = 0.04), while year of diagnosis (OR = 0.89; 95%CI: 0.83, 0.96; P = 0.003) predicted the opposite. The 5-year IPTW-adjusted rates of OS were 99% and 97% in the AT and initial surveillance groups, respectively (HR = 0.36; 95%CI: 0.12, 1.14; P = 0.08). Among men with non-seminoma, 47% received AT (chemo = 38%, RPLND = 9%) while 53% received initial surveillance. The use of AT remained stable over the study period (APC = +0.8; 95%CI: -0.7, +2.2; P = 0.29). Predictors of receiving AT included stage ≥ pT2 (OR = 1.78; 95%CI: 1.06, 3.00; P = 0.03), and lymphovascular invasion (OR = 2.68; 95%CI: 1.88, 3.83; P < 0.001). The 5-year IPTW-adjusted rates of OS were 97% and 95% in the AT and initial surveillance groups, respectively (HR = 0.66; 95%CI: 0.27, 1.61; P = 0.36). Conclusions: Trends in the use of AT for stage IS testicular cancer differed according to histologic type. Nonetheless, we report 5-year OS rates of ≥ 95% for seminoma and non-seminoma without any significant benefit with the use of AT.
