Öğe Clinical characteristics and treatments outcomes in elderly patients with multiple myeloma: A multicenter retrospective study(2017) Terzi, Hatice; Korkmaz, Serdal; Berber, İlhami; Keklik, Muzaffer; Doğu, Mehmet Hilmi; Şencan, Mehmet; Kaya, Emin; Eser, Bülent; Sarı, İsmail; İlhan, OsmanAbstract: Amaç: Mutipl Myeloma, tüm kanser tiplerinin %1' ini, hematolojik malignitelerin ise %10' unu oluşturan tamamen kürün sağlanamadığı fatal bir hastalıktır. Genellikle yaşlı populasyonda izlenir. Bu çalışmanın amacı, son 5 yılda farklı rejimlerle tedavi edilen 65 yaş ve üzerindeki 105 Mutipl Myeloma' lı hastadaki klinik deneyimimizi sunmaktır. Yöntem: 65 yaş üzerindeki Mutipl Myeloma'lı hastaların klinik karakterleri ve terapötik sonuçlarını analize etmek için, Türkiye'deki 5 farklı merkezden retrospektif olarak veriler toplandı.Bulgular: 51 erkek ve 54 kadından oluşan toplam 105 yaşlı Multipl Myeloma hastası (65 yaş ve üzeri) retrospektif olarak değerlendirildi. Hastalara ilk basamak olarak, VAD( vinkrsitin, adriamisin, deksametazon), VCD ( Bortezomib, siklofosfamid, deksametazon), MP( melphalan, prednizolon), MPT (Melphalan, prednizolon, thalidomid) rejimleri verildi. 29 hastada tam yanıt elde edildi ve bu hastaların 18 'ine otolog kök hücre nakli yapıldı. Tam yanıt elde edilemeyen 46 hastaya, ikinci basamak tedavi olarak bortezomib, lenalidomid ve talidomid bazlı rejimler verildi. İkinci basamak tedavi ile tedavi edilenlerin 29'unda tam yanıt elde edildi ve bu hastalardan 20'sine otolog kök hücre nakli yapıldı. 16 hastaya ise birinci ve ikinci basamak rejimlere yanıt vermediğinden lenalidomid bazlı rejimler (n: 10), talidomid bazlı rejimler (n: 6) verildi. Bu tedavilerle remisyona giren 5 hastaya Otolog kök hücre nakli yapıldı. Sonuç: Optimal tedavi yaklaşımı, verimli, güvenli, kaliteli yaşam sağlamalı ve amaç tam yanıtın yanı sıra hastalıksız sağ kalımı ve genel sağ kalımı uzatmak olmalıdırÖğe CLINICAL CHARACTERISTICS, POST-TREATMENT ASSESSMENT AND PROGNOSTIC FACTORS AFFECTING PATIENT SURVIVAL OF PATIENTS AT 65 YEARS OF AGE OR OLDER WITH HODGKIN LYMPHOMA: A RETROSPECTIVE MULTICENTER STUDY FROM TURKEY(Carbone Editore, 2015) Berber, Ilhami; Erkurt, Mehmet Ali; Keklik, Muzaffer; Dogu, Mehmet Hilmi; Terzi, Hatice; Pala, Cigdem; Sari, Hakan IsmailIntroduction: During the last three decades, major advances have been made in the therapy of Hodgkin's lymphoma. However, despite these advances, Hodgkin's lymphoma has a poor prognosis in the elderly. The proportion of Hodgkin's lymphoma patients aged > 60 ranges in the different reports between 15% and 35%. This study aimed to examine clinical characteristics, treatment outcomes and prognostic factors affecting patient survival in Hodgkin's lymphoma patients aged 65 years or older. Material methods: Hodgkin's lymphoma patients at 65 years of age and older managed within last 5 years in a total of 5 centers in Turkey were retrospectively assessed. Results: The median age of a total of 32 patients was 71 (65-83) years. Elderly patients presented more frequently with B symptoms, elevated sedimentation rate, mixed cellularity histologic subtype and comorbid disease. Less frequent were bulky disease, bone marrow involvement, and the application of autologous stem cell transplantation. The nodular lymphocyte predominant subtype and lymphocyte rich subtype were not observed at all. Eastern Cooperative Oncology Group, ferritin, total protein, and histological type were significant predictors affecting survival (p<0.05). Conclusions: Hodgkin's lymphoma is a more fatal disease in 65 years of age or older, when compared to the young population. Tumor biology, older age itself, and other factors related to comorbidity probably contribute to the worse outcome of elderly patients. Further large-scale studies are needed to better investigate the factors that were significant predictors of patient survival.Öğe Diffuse Large B-Cell Lymphoma in adults aged 65 years and older: A retrospective multicenter analysis of clinical characteristics and therapeutic outcomes(Cig Media Group, Lp, 2015) Dogu, Mehmet Hilmi; Keklik, Muzaffer; Terzi, Hatice; Korkmaz, Serdal; Erkurt, Mehmet Ali; Cagliyan, Gulsum Akgun; Kaynar, Leylagul[Abstract Not Available]Öğe A Multi-Center Study on the Efficacy of Eltrombopag in Management of Refractory Chronic Immune Thrombocytopenia: A Real-Life Experience(2019) Çekdemir, Demet; Güvenç, Serkan; Özdemirkıran, Füsun; Eser, Ali; Şahin Haydaroğlu, Handan; Turak Ermiş, Esra; Esen, Ramazan; Cömert, Melda; Sadri, Sevil; Aslaner, Müzeyyen; Uncu Ulu, Bahar; Karakuş, Abdullah; Bapur Selim, Derya; Alacacıoğlu, İnci; Aydın, Demet; Tekinalp, Atakan; Namdaroğlu, Sinem; Ceran, Funda; Tarkun, Pınar; Kiper, Demet; Çetiner, Mustafa; Yenerel, Mustafa; Demir, Muzaffer Ahmet; Yılmaz, Güven; Terzi, Hatice; Atilla, Erden; Malkan, Yavuz Ümit; Acar, Kadir; Öztürk, Erman; Tombak, Anıl; Sunu, Cenk; Salim, Ozan; Alayvaz, Nevin; Sayan, Özkan; Ozan, Ülkü; Ozan, Mesut; Gökgöz, Zafer; Andıç, Neslihan; Kızılkılıç, Ebru; Noyan, Figen; Özen, Mehmet; Tanrıkulu Pepedil, Funda; Alanoğlu, Güçhan; Özkan, Hasan Atilla; Aslan, Vahap; Çetin, Güven; Akyol Erikçi, Alev; Deveci, Burak; Ersoy Dursun, Fadime; Dermenci, Hasan; Aytan, Pelin; Gündüz, Mehmet; Karakuş, Volkan; Özlü, Can; Demircioğlu, Sinan; Akay Yanar, Olga Meltem; Özatlı, DüzgünAbstract: Objective: The aim of the present study was to evaluate the efficacyand safety of eltrombopag, an oral thrombopoietin receptor agonist,in patients with chronic immune thrombocytopenia (ITP).Materials and Methods: A total of 285 chronic ITP patients (187women, 65.6%; 98 men, 34.4%) followed in 55 centers were enrolledin this retrospective cohort. Response to treatment was assessedaccording to platelet count (/mm3) and defined as complete (plateletcount of >100,000/mm3), partial (30,000-100,000/mm3 or doublingof platelet count after treatment), or unresponsive (<30,000/mm3).Clinical findings, descriptive features, response to treatment, and sideeffects were recorded. Correlations between descriptive, clinical, andhematological parameters were analyzed.Results: The median age at diagnosis was 43.9±20.6 (range: 3-95)years and the duration of follow-up was 18.0±6.4 (range: 6-28.2)months. Overall response rate was 86.7% (n=247). Complete andpartial responses were observed in 182 (63.8%) and 65 (22.8%)patients, respectively. Thirty-eight patients (13.4%) did not respondto eltrombopag treatment. For patients above 60 years old (n=68),overall response rate was 89.7% (n=61), and for those above 80 years old (n=12), overall response rate was 83% (n=10). Consideringthrombocyte count before treatment, eltrombopag significantlyincreased platelet count at the 1st, 2nd, 3rd, 4th, and 8th weeks oftreatment. As the time required for partial or complete responseincreased, response to treatment was significantly reduced. The timeto reach the maximum platelet levels after treatment was quitevariable (1-202 weeks). Notably, the higher the maximum plateletcount after eltrombopag treatment, the more likely that side effectswould occur. The most common side effects were headache (21.6%),weakness (13.7%), hepatotoxicity (11.8%), and thrombosis (5.9%).Conclusion: Results of the current study imply that eltrombopag isan effective therapeutic option even in elderly patients with chronicITP. However, patients must be closely monitored for response andside effects during treatment. Since both response and side effectsmay be variable throughout the follow-up period, patients should beevaluated dynamically, especially in terms of thrombotic risk factors.
