    Purpose: This study aimed to analyze prognostic factors for survival and the reliability and the effectiveness of eribulin therapy in metastatic breast cancer (MBC) patients. Methods: A total of 80 patients treated with eribulin in 12 medical oncology centers in Turkey between 2013-2017 were retrospectively evaluated. Sixteen potential prognostic variables were assessed for analysis. Results: The patients had received a median of 5 prior chemotherapy regimens and a median of 3 eribulin cycles for MBC. Median progression-free survival (PFS) was 5.5 months (95% Cl: 4.1-7.8) and median overall survival (OS) was 11 months (95 % Cl: 6-15). Multivariate analysis showed that eribulin treatment line was shown to have independent prognostic significance for PFS. PFS difference was demostrated in patients who received 3 chemotherapy lines for advanced disease compared to those who had more than 3 chemotherapy lines [median PFS; 3 lines: 8.6 months (6.2-11) and >3 lines: 4.6 months (3.7-4.6) p=0.00]. The clinical benefit rate (CBR) was 52.5 and 35% in patients treated with three lines and with >3 previous chemotherapeutic regimens. Most common toxicities were neutropenia (62.5%), fatigue (52.5%), alopecia (50%) and nausea (37.5%). Conclusions: Eribulin treatment line was identified as in-depedent prognostic factor for PFS in MBC patients. © 2019 Zerbinis Publications. All rights reserved.

    Efficacy of everolimus plus hormonal treatment after cyclin-dependent kinase inhibitor; real-life experience, A TOG study
    (Springer, 2024) Beypınar İ.; Demir H.; Yaslıkaya Ş.; Köşeci T.; Demir B.; Çolak G.; Ağaoğlu A.B.; Şahbazlar M.; Şancı P.C.; Çabuk D.; Işık U.; Şahin E.; Coşkun A.; Caner B.; Aykut T.; Artaç M.; Duygulu M.E.; Sever N.; Öksüz S.; Turan N.; Aykan M.B.; Tüzün E.K.; Uysal M.; Uğurlu İ.; Sakin A.; Acar C.; Özaşkın D.; Şakalar T.; Keskinkılıç M.; Yavuzşen T.; Köse N.; Ertürk İ.; Yıldırım N.; Balçık O.Y.; Alkan A.; Selvi O.; Erçin E.; Ünal O.Ü.; Karaçin C.
    Purpose: In advanced breast cancer, endocrine therapy is preferred in the absence of visceral crisis. Cyclin-dependent kinase inhibitors (CDKi) are the gold standards. The selection of subsequent treatments after CDKi treatment is still controversial, and the efficacy of everolimus (EVE) combinations is unknown. In this study, we aimed to investigate the efficacy of EVE after CDKi administration in real-life experiences. Method: The study received data from 208 patients from 26 cancer centers. Demographic and histologic features, diagnosis, progression, last visit dates, and toxicities were recorded. This study was a retrospective case series. Results: One hundred and seven patients received palbociclib, while 101 patients received ribociclib as a CDKi. The overall response and disease control rates of EVE combinations were 60% and 88%, respectively. In univariate analysis, the absence of liver metastasis, age > 40 years, better type of response, and immediate treatment after CDKi were related to increased progression-free survival. Liver metastasis and response type were significantly associated with overall survival. In the multivariate analysis, response remained significant in terms of progression-free survival, while response type, liver metastatic disease, and hematologic toxicity were prognostic in terms of overall survival. Conclusion: This study provides evidence of the benefits of EVE combinations after CDKi treatment. EVE combinations may be more appropriate for patients with non-liver metastasis, and the first treatment response shows the benefit of treatment. In addition, immediate treatment after CDKi treatment is more beneficial than later lines of treatment. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
