184 Background: Global neoadjuvant and adjuvant treatment patterns among patients with resected Esophageal Cancer (EC) and Gastroesophageal Junction cancer (GEJC) remain unclear. This study describes real-world treatment patterns and outcomes for patients receiving surgery for Stage II or III EC or GEJC. Methods: Physicians in North America (US, Canada), Asia (China, Japan, Taiwan), and Europe (UK, France, Germany, Italy, Spain) provided clinical and treatment data in this retrospective, non-interventional chart review conducted from April-June 2020. Included patients were adults (Japan ≥20 years; elsewhere, ≥18 years), who underwent resection of Stage II or III EC or GEJC between October 2017 and October 2018 and were followed until death, loss to follow up, or end of data collection. Results: Physicians (N = 609) provided data on 1693 patients of mean age of 62.4 years, who received surgery for Stage II or III esophageal squamous cell carcinoma (ESCC) (33.3%), esophageal adenocarcinoma (EAC) (31.5%), or GEJC (35.2%) and were followed a mean (median) of 17.7 (17) months (to death or end of study period). At diagnosis, 85.6% of patients had performance status of 0/1. The majority of patients received an R0 resection (overall, 70.6%; ESCC, 76.6%, EAC, 67.4%, GEJC, 68.0%; p < 0.05); of these, 32.0% had a complete pathological response and 64.1% had a partial pathological response. Neoadjuvant therapy use differed among the treatment groups (ESCC 56.5%; EAC, 65.9%; GEJC, 62.6%, p < 0.05), as did adjuvant therapy (ESCC: 39.8%; EAC, 40.3%; GEJC, 44.5%; p = 0.023). Recurrence rate following surgery did not differ between groups for any recurrence (overall, 21.0%; ESCC 18.5%, EAC 23.6%, GEJC 21.1%); for local or regional recurrence (overall, 11.6%; ESCC, 10.3%; EAC, 12.7%; GEJC, 11.7%); or for metastatic recurrence (overall, 9.5%; ESCC, 8.2%; EAC, 10.9%; GEJC, 9.4%). The median time to local or regional recurrence (for those who progressed during the reporting period) was 8 months from date of initial surgery (overall, 8 mo; ESCC, 8 mo; EAC, 7 mo; GEJC, 8.5 mo; p > 0.05). The frequency of 1L systemic therapy for advanced disease at the time of survey completion was 16.1% overall and differed among patients with ESCC (14.6%); EAC (17.8%); and GEJC (15.9%); p > 0.05. Conclusions: This large multi-country real world data study shows that over half of all patients received neoadjuvant therapy, and over a third received adjuvant treatment. The high unmet need in this population is evident from the post-resection recurrence rate of 21.1% at median 8 months and the high proportion of patients who went on to require advanced disease treatment.

e18042 Background: The clinical utility of maintenance therapy (MT) for patients with platinum-sensitive recurrent ovarian cancer (PSROC) has been validated in several clinical trials. We assessed real world treatment patterns using a US nationwide electronic health record database. Methods: A retrospective study of patients with PSROC between March 2017 and July 2019 was conducted using the Flatiron Health database. This longitudinal, demographically and geographically diverse de-identified database covers > 2.2 million oncology patients in > 280 cancer clinics. Patients were excluded if second or third line (2L or 3L) platinum-based chemotherapy (PBT) regimens included less than four or more than eight cycles of platinum. Information regarding somatic or germline BRCA mutations and homologous recombination deficiency (HRD) were obtained. Results: 2292 patients with PSROC were identified (had 2L or 3L treatment); 1214 of these received PBT at recurrence; 610 completed the PBT for recurrence on or after March 2017; 351 received 4–8 cycles of PBT; 225 patients had ≥2 months of active surveillance or were receiving MT of PARPi or bevacizumab (B) and were included in this analysis. 183 patients (80%) had BRCA testing and 14 patients (6%) had HRD testing. 46 (20%) had a germline or somatic BRCA mutations (t BRCA), 134 (59%) had a wildtype wt BRCA gene, and 48 (21%) were unknown. Of patients with tBRCA, 63% received a PARP inhibitor (PARPi), 17% received B, 20% received active surveillance. Of patients with wt BRCA, 40% received a PARPi, 24% received B, and 37% received active surveillance. Olaparib was the most commonly used PARPi among tBRCA patients (26%), while niraparib was most commonly used among wt BRCA patients (21%). MT was more common in younger patients, those with a better performance status and with a BRCA mutation. MT use trend increased by 21% during the study period. As PARPi use increased, the use of active surveillance as a post-platinum regimen decreased during the later time periods (Table). Conclusions: In this real world population, the majority of patients with PSROC are receiving maintenance therapy. While genetic testing is improving, universal testing of all patients with ovarian cancer remains the goal. The results provide insight into the shifting treatment patterns for patients with ovarian cancer. [Table: see text]

Stage Disease

**Background:** In 2020, approximately 3100 Canadian women were diagnosed with ovarian cancer (OC), with 1950 women dying of this disease. Prognosis for OC remains poor, with 70% to 75% of cases diagnosed at an advanced stage and an overall 5-year survival of 46%. Current standard of care in Canada involves a combination of cytoreductive surgery and platinum-based chemotherapy. **Objective:** There are few studies reporting current OC costs. This study sought to determine patient characteristics and costs to the health system for OC in Ontario, Canada. **Methods:** Women diagnosed with OC in Ontario between 2010 and 2017 were identified. The cohort was linked to provincial administrative databases to capture treatment patterns, survival, and costs. Overall total and mean cost per patient (unadjusted) were reported in 2017 Canadian dollars, using a macro-based costing methodology called GETCOST. It is programmed to determine the costs of short-term and long-term episodes of health-care resources utilized. **Results:** Of the 2539 OC patients included in the study, the mean age at diagnosis was 60.4±11.35 years. The majority were diagnosed with stage III disease (n=1247). The only treatment required for 74% of stage I patients and 54% of stage II patients was first-line (1L) platinum chemotherapy; in advanced stages (III/IV) 24% and 20%, respectively, did not receive further treatment after 1L therapy. The median overall survival (mOS) for the whole cohort was 5.13 years. Survival was highest in earlier stage disease (mOS not reached in stage I/II), and dropped significantly in advanced stage patients (stage III: mOS=4.09 years; stage IV: mOS=3.47 years). Overall mean costs in patients stage I were CAD $58 099 compared to CAD $124 202 in stage IV. **Discussion:** The majority of OC patients continue to be diagnosed with advanced disease, which is associated with poor survival and increased treatment costs. Increased awareness and screening could facilitate diagnosis of earlier stage disease and reduce high downstream costs for advanced disease. **Conclusion:** Advanced OC is associated with poor survival and increased costs, mainly driven by hospitalizations or cancer clinic visits. The introduction of new targeted therapies such as olaparib could impact health system costs, by offsetting higher downstream costs while also improving survival.
