Treatment patterns by decade of life in elderly women (≥70 years of age) with ovarian cancer

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]

ObjectiveDespite the considerable disease burden of ovarian cancer, there were no cost studies in Central and Eastern Europe. This study aimed to describe treatment patterns, health care utilization, and costs associated with treating ovarian cancer in Hungary, Poland, Serbia, and Slovakia.MethodOverall clinical practice for management of epithelial ovarian cancer was investigated through a 3-round Delphi panel. Experts completed a survey based on the chart review (n = 1542). The survey was developed based on clinical guidelines and the International Federation of Gynecology and Obstetrics Annual Report. Means, ranges, and outlier values were discussed with the experts during a telephone interview. Finally, consensus estimates were obtained in face-to-face workshops. Based on these results, overall cost of ovarian cancer was estimated using a Markov model.ResultsThe patients included in the chart review were followed up from presurgical diagnosis and in each phase of treatment, that is, surgical staging and primary surgery, chemotherapy and chemotherapy monitoring, follow-up, and palliative care. The 5-year overall cost per patient was €14,100 to €16,300 in Hungary, €14,600 to €15,800 in Poland, €7600 to €8100 in Serbia, and €12,400 to €14,500 in Slovakia. The main components were chemotherapy-associated costs (68%–74% of the total cost), followed by cost of primary treatment with surgery (15%–21%) and palliative care (3%–10%).ConclusionsPatients with ovarian cancer consume considerable health care resources and incur substantial costs in Central and Eastern Europe. These findings may prove useful for clinicians and decision makers in understanding the economic implications of managing ovarian cancer in Central and Eastern Europe and the need for innovative therapies.
