New treatment modalities have been recently introduced in the management of ovarian cancer (OC). Herein, we sought to investigate their implementation in routine clinical practice and examine the real-world management of OC in Greece. EpOCa was a non-interventional, multicenter, retrospective study in patients with advanced epithelial OC. The primary outcome was to estimate the proportions of the different treatment regimens used per line of therapy, while progression-free survival (PFS) and overall survival (OS) were the key secondary endpoints. A total of 154 patients were enrolled in the study, among whom, 40% were tested for BRCA mutations and 30% were found to be positive. Nearly 90% of patients underwent debulking surgery at diagnosis, with few operations being also recorded upon relapse. Platinum-based chemotherapy (CT) was predominantly used in the first line with half of patients also receiving angiogenesis inhibitor (AI), while non-platinum-based CT was preferred in later lines. The median PFS was 18.2 and 8.8 months in the first- and second-line setting, respectively, whereas the median OS was approximately 50 months. Our study adds to the available, but limited, real world data on the management of ovarian cancer providing evidence regarding the applied treatment strategies and outcomes of patients in Greece.

In the realm of HER2-positive (HER2+) metastatic breast cancer (MBC), the advent of targeted therapies, notably trastuzumab and pertuzumab, represents a substantial advancement in enhancing patient outcomes. However, the intricacies of treatment escalate when patients encounter progression or resistance during first-line (1L) therapy. The togetHER study aimed to elucidate real-world insights into the profile, management strategies, and outcomes for HER2+ MBC patients initiating second-line treatment (2LT) in Greece, predating recent international guideline changes incorporating trastuzumab deruxtecan and tucatinib in the second line and beyond lines of treatments. Data from adult female patients with HER2+ MBC who had initiated 2LT between 01-Jan-2015 and 31-Dec-2018 in 18 oncology departments across Greece were retrospectively abstracted through medical chart review. The eligible population comprised 122 patients, 68.0% of whom presented with recurrent MBC. Among the latter, 26.5% were tested for HER2 both in early and metastatic settings with 27.3% of them changing HER2 status from negative to positive. Retesting of HER2 expression following 2LT initiation was recorded in 8 cases. At 2LT initiation, patients’ median age was 57.0 years and 63.6% were hormone receptor-positive. The most common metastatic sites were bone (56.6%), lung (44.3%), liver (41.0%), and brain (29.5%). Anti-HER2 agent usage in 1L and 2L stood at 91.8% and 92.6%, respectively, with rates slightly diminishing in third (3L) (85.9%) and fourth line (4L) (82.4%). Endocrine therapy administration was generally low across treatment lines (12.3%, 9.9%, and 5.9%, in 2L, 3L, and 4L respectively), while chemotherapy use increased from 30.3% in 2L to 47.9% and 47.1% to 3L and 4L, correspondingly. Median progression-free survival (PFS) for 2L, 3L, and 4L was 7.7 [95% confidence interval (CI) 6.0–14.4], 6.4 (95% CI 5.4–7.1), and 5.6 (95% CI 2.6–9.0) months, respectively, while median overall survival was 25.0 (95% CI 20.5–34.4) months. Although the 2LT pattern in Greece generally aligned with guidelines, persistently poor treatment outcomes underscore a significant unmet medical need for these patients.
