Öğe Adrenocortical Cancer in the Real World: A Comprehensive Analysis of Clinical Features and Management from the Turkish Oncology Group (TOG)(Cig Media Group, Lp, 2024) Yasar, Hatime Arzu; Aktas, Burak Yasin; Ucar, Gokhan; Goksu, Sema Sezgin; Bilgetekin, Irem; Cakar, Burcu; Sakin, AbdullahAdrenocortical cancer is a rare and poor prognostic malignant tumor. The definitions of prognostic factors in localized and metastatic diseases are important. In this paper, we defined the clinical features, management, and prognostic factors related to survival in patients with metastatic and nonmetastatic ACC. Cox regression analysis showed that age, Ki67 value, ECOG PS, and hormonal activity were significantly associated with survival in patients with nonmetastatic disease. Only patients who underwent surgery had significantly better OS compared with patients without surgery in univariate analyses of metastatic disease. Introduction: Adrenocortical carcinoma (ACC) is a rare yet highly malignant tumor associated with significant morbidity and mortality. This study aims to delineate the clinical features, survival patterns, and treatment modalities of ACC, providing insights into the disease's prognosis. Materials and Methods: A retrospective analysis of 157 ACC patients was performed to assess treatment methodologies, demographic patterns, pathological and clinical attributes, and laboratory results. The data were extracted from the hospital's database. Survival analyses were conducted using the Kaplan-Meier method, with univariate and multivariate analyses being performed through the log -rank test and Cox regression analyses. Results: The median age was 45, and 89.4% had symptoms at the time of diagnosis. The median tumor size was 12 cm. A total of 117 (79.6%) patients underwent surgery. A positive surgical border was detected in 26 (24.1%) patients. Adjuvant therapy was administered to 44.4% of patients. The median overall survival for the entire cohort was 44.3 months. Median OS was found to be 87.3 months (95% confidence interval [CI] 74.4-100.2) in stage 2, 25.8 (95% CI 6.5-45.1) months in stage 3, and 13.3 (95% CI 7.0-19.6) months in stage 4 disease. Cox regression analysis identified age, Ki67 value, Eastern Cooperative Oncology Group performance status, and hormonal activity as significant factors associated with survival in patients with nonmetastatic disease. In metastatic disease, only patients who underwent surgery exhibited significantly improved overall survival in univariate analyses. Conclusion: ACC is an uncommon tumor with a generally poor prognosis. Understanding the defining prognostic factors in both localized and metastatic diseases is vital. This study underscores age, Ki67 value, Eastern Cooperative Oncology Group performance status, and hormonal activity as key prognostic determinants for localized disease, offer ing cr itical insights into the complexities of ACC management and potential avenues for targeted therapeutic interventions.Öğe Efficacy of regorafenib in the second-and third-line setting for patients with advanced hepatocellular carcinoma: A real life data of multicenter study from Turkey(Imprimatur Publications, 2020) Hacioglu, Muhammet Bekir; Kostek, Osman; Karabulut, Senem; Tastekin, Didem; Goksu, Sema Sezgin; Alandag, Celal; Akagunduz, BaranPurpose: After failure of the first-line sorafenib treatment in advanced or metastatic stage hepatocellular carcinoma (HCC), regorafenib is one of the newly-approved targeted agents. We aimed to evaluate the efficacy of regorafenib in patients with advanced HCC treated in the secondor third-line setting. Methods: In this retrospective and multicenter study, advanced HCC patients not eligible for local therapies, who received a secondor third-line regorafenib therapy after progression on the first-line sorafenib or sequential therapy with chemotherapy (CT) followed by sorafenib, were included. Results: In the first-line setting, 28 (28.9%) patients received CT and 69 (71.1%) patients received sorafenib. There were 24 (24.7%) patients who were intolerant to sorafenib. Disease control rate (DCR) was 53.6% for all patients treated with regorafenib, 62.3% in patients who received regorafenib in the second-line, and 32.1% for those receiving regorafenib in the third-line (p=0.007). Median progression-free survival (PFS) and overall survival (OS) were 5.6 (range; 4.3-6.9) and 8.8 (range, 6.3-11.3) months for all patients treated with regorafenib vs. 7.1 months and 10.3 months for patients who received regorafenib in the second-line vs. 5.1 and 8.7 months for patients who received regorafenib in the third-line, respectively; however, there was no statistically significant difference (p(PFS)=0.22 and p(OS)=0.85). Conclusion: Although receiving CT as a first-line therapy in advanced HCC patients did not affect the survival rates of subsequent regorafenib therapy, it might diminish the DCR of regorafenib.Öğe Retrospective analysis of ribociclib and letrozole as first-line therapy in patients with hormone receptor (HR) positive metastatic breast cancer (MBC) within a managed access program (MAP) in Turkey.(Lippincott Williams & Wilkins, 2020) Basaran, Gul; Demirci, Umut; Yildiz, Fatih; Cicin, Irfan; Aktas, Burak Yasin; Ozturk, Banu; Goksu, Sema Sezgin[Abstract Not Available]Öğe Ribociclib for the treatment of hormone receptor-positive refractory advanced breast cancer: Managed access programme in Turkey(Amer Assoc Cancer Research, 2020) Demirci, Umut; Gokmen, Erhan; Eralp, Yesim; Gunduz, Seyda; Goksu, Sema Sezgin; Korkmaz, Taner; Kostek, Osman[Abstract Not Available]
