GENERAL CLINICAL EVALUATION OF THE CHRONIC LYMPHOCYTIC LEUKEMIA PATIENTS

Amaç: Çalışmamızda 2000-2011 yılları arasında Dokuz Eylül Üniversitesi Tıp FakültesiHematoloj Bilim Dalı tarafından takip edilen 114 hastanın demografik verileri, tedaviendikasyonları, tedavi yanıtları ve total sağ kalım analizlerinin yapılması amaçlandı.Yöntemler: Kronik lenfoblastik lösemi tanısıyla takip edilen 114 hastanın verilerigeriye dönük olarak değerlendirildi.Bulgular: Hastaların 60'ı erkek (%52,6), 54'ü kadındı (%47,4). Ortanca yaş 64 olaraksaptandı. 61 hasta tedavisiz izlenirken 53 hasta tedavi aldı. Tanıdan ilk tedaviye kadargeçen süre ortalama 15,57 ay idi. İlk sıra kemoterapide en sık klorambusil kullanıldı(%62). Hastaların ilk sıra kemoterapi sonrası yapılan değerlendirmelerinde 40 hastadakısmi yanıt, 5 tam yanıt, 7 stabil hastalık ve 1 hastada progresyon izlendi veprogresyonsuz sağ kalım ortalaması 18 ay olarak bulundu. 25 hasta ikinci sırakemoterapi aldı. İkinci sıra kemoterapinin progresyonsuz sağ kalım ortalaması 6,23 ayolarak hesaplandı. 6 hastaya üçüncü sıra kemoterapi verildi ve üçüncü sıra kemoterapininprogresyonsuz sağ kalım ortalaması 5,5 ay idi. Çalışma sonunda 114hastanın ortalama toplam sağ kalım süreleri 92,8 ay olarak hesaplandı. Rai ve Binetevresi yüksek olan hastalarda tedavisiz sağ kalım ve progresyonsuz sağ kalımsürelerinin kısaldığı görüldü (p<0,05). Çalışma süresinde 14 hasta hastalık ilişkilinedenlerle 9 hasta hastalık dışı nedenlerle hayatını kaybetti.Sonuç: Hastalarımızın demografik özellikleri diğer çalışmalarla benzer iken tedavi alanhastalarda toplam sağ kalım süresinin daha kısa olmasının nedeni gelişmiş prognostikbelirteçlerin merkezimizde kullanılmaması, ilk sıra tedavilerde monoklonalantikorların yer almaması ve yetersiz hasta uyumu olabilir. Objectıve: Demographic features, treatment endications, responds to treatment of 114chronic lymphocytic leukemia patients observed in years of 2000-2011 on hematologydepartment of Dokuz Eylül University Medical Faculty have been analyzed in ourstudy.Methods: Features of 114 CLL patients were evaluated retrospectively.Results: In 60 patients were male (%52.6), 54 patients were female(%47.4). The medianage was 64. While 61 patients were being observed without treatment, 53 patients were under medical treatment. The therapy free survival was 15.57 months. Chlorambucilwas the most prefered drug on the first line therapy (%62). In the evaluation first linechemotherapy; partial remission for 40, complete remission for 5, stable disease for 7,progression for 1 patient was observed.Progression free survival was 18 months. 25patients have second line therapy. The progression free survival of the second linetherapy was 6.23 months. The third line therapy was given to 6 patients, theprogression free survival of the third line therapy was 5,5 months. At the end of thestudy overall survival was 92.8 months. For the patients whose Rai and Binet stage ishigh, therapy free survival and progression free survival 1 time is shorter (p<0.05).During the study deaths of the 14 patients were related to the CLL and 9 patientsrelated to another reasons.Conclusıon: Demographic features of patients are similar to other studies. Causes ofshorter survival time in therapy group may be related to lack of using modernprognostic markers in our center, lack of using monoclonal antibodies on the first linetherapy and poor patient adaptation to treatmen

EVALUATION OF CLINICAL PROGRESS AND THERAPY RESPONSE OF PATIENTS WITH IMMUNE THROMBOCYTOPENİC PURPURA; SINGLE CENTER EXPERIENCE

Amaç: İmmun Trombositopeni (İTP), trombositlere karşı oluşan otoantikorların trombositlerin yaşam sürelerini kısaltması sonucu gelişen ve trombositopeni ile seyreden edinsel bir hastalıktır. Trombositopeninin derecesine bağlı olmak üzere, sıklıkla, purpurik deri lezyonları, mukozal kanamalar, nadiren iç organ kanamaları gibi hayatı tehdit eden kanamalar gelişir. Yöntemler: Bu çalışmada 1988 - 2011 yılları arasında tedavi ve takiplerine merkezimizce devam edilen 76 hastanın sonuçları retrospektif olarak değerlendirilmiştir. Bulgular: 76 hastanın 49'u kadın (%64,5), 27'si erkek (%35,5) olup, ortanca yaş 50,7 (19 - 83 yıl) idi. Olguların 20'si tedavisiz takip edilmiş, tedavi uygulanan 56 olgunun 53'ünde (%92) ise başlangıç tedavisi olarak 1 mg/kg metil prednizolon uygulanmıştı. Bu hastaların 24'ünde (%44,6) tam yanıt, 13'ünde (%23,2) yanıt elde edilmiş ve 17 (%31,5) olguda ise yanıt alınamamıştı. Steroide yanıt vermeyen ya da yanıt sonrası nüks eden hastalara splenektomi uygulanmıştı (37 hasta). Bu hastalardan 33'ünde tam yanıt, 2'sinde yanıt elde edilirken, 2 hastada yanıt alınamadı. Toplamda 8 hastaya Rituksimab verildi. 3 hastada tam yanıt, 2 hastada yanıt alındı. 3 hastada ise yanıt elde edilemedi. Sonuç: ITP hastalarında başlangıç prednizolon tedavisi ve splenektomi, olguların çoğunda etkili bir tedavi seçeneği olmakla birlikte, bu tedavilere cevap vermeyen refrakter ITP olgularında ise ritüksimab kullanımı etkili bir tedavi seçeneğidir. Objective: Immune thrombocytopenia (ITP) is an autoimmune thrombocytopenic disease characterized by destruction of platelets mainly at spleen in reticuloendothelial system. The initiation of ITP is mostly insidious, usually defined with mild to moderate history of hemorrhage. Rarely, life threatining bleeding episodes are documented. Methods: 76 ITP patients diagnosed at Dokuz Eylul University Faculty of Medicine Hospital from 1988 to 2011 are included in this retrospective study. Results: 49 of 76 (64.4%) patients were female and 27 patients diagnosed as ITP were male (35,5%) (F/M: 1.81). At diagnosis the median age of patients was 50.7 (Interval; 19 - 83). 20 patients were followed without any treatment. 53 of 56 patients (92%) in treated group received 1 mg/kg methyl prednisolone. 24 patients (44.6%) achieved complete response after initial steroid therapy, 13 patients (23.2%) were followed with partial response and 17 patients (31.5%) had no response. Splenectomy was applied to patients that were not responded or relapsed after steroid treatment. After splenectomy 33 patients achieved complete response, 2 patients achieved partial response and 2 patients were followed as nonresponders to splenectomy. Totally 8 patients received rituximab. 3 of 8 patients (37.5%) were complete responders, 2 of 8 patients (25%) were partial responders on the other hand 3 of 8 patients (37.5%) were nonresponders. Conclusion: Most of the patients are successfully treated with steroids or splenectomy. Hence, in relapsed and refractory ITP after splenectomy rituximab is an effective treatment option

PERIPHERAL BLOOD STEM CELL TRANSPLANTATION FOR LYMPHOMA PATIENTS: SINGLE CENTER EXPERIENCE

Renal and Neurological Response with Eculizumab in a Patient with Transplant Associated Thrombotic Microangiopathy after Allogeneic Hematopoietic Progenitor Cell Transplantation

Transplantation-associated thrombotic microangiopathy (TA-TMA) is a challenge after allogeneic hematopoietic progenitor cell transplantation, considering the diagnostic uncertainties and lack of established treatment. We report a 43-year-old male patient who was diagnosed as TA-TMA after allogeneic progenitor cell transplantation for a progressive ALK negative anaplastic large cell lymphoma and responded to eculizumab with dramatically improving neurological status and renal function. Rapid neurological and renal recovery achieved after eculizumab could support a possible relationship between complement activation and TA-TMA. Eculizumab should be a reasonable treatment approach in patients with TA-TMA after allogeneic hematopoietic progenitor cell transplantation

Does Reinfusion of Stem Cell Products on Multiple Days Affect Engraftment?

Objective: High-doses of melphalan treatment with autologous stem cell transplantation in multiple myeloma (MM) remains a major treatment modality in suitable patients. A minimal dose of 2x106/kg CD34+ cells is preferred to achieve engraftment. Some patients need multiple leukapheresis procedures to achieve the necessary number of CD34+ cells, but this can cause a high volume of stem cell product that cannot be given in a single day. Whether or not the number of infusion days affects engraftment has not been studied before. We aimed to evaluate the impact of reinfusion of stem cells on multiple days on engraftment results. Materials and Methods: Demographic features, CD34+ cell doses, neutrophil and platelet engraftment days, hospitalization days, and number of infusion days of 149 autologous transplantations of 143 MM patients were evaluated retrospectively. Results: The data of 143 MM patients who were transplanted were analyzed retrospectively. Median age was 55±8.5 (range: 26-70) years with a male/female ratio of 91/58. Hospitalization days for all patients were 24±6 (range: 14-50) days. Mean CD34+ cell number was (7.5±5.3) x106/kg (range: 1.5-31x106/kg). CD34+ cells were reinfused in 1 day in 80.5% (n=120) of the patients, 2 days in 18.2% of the patients (n=27), and 3 days in 1.3% of the patients (n=2). For 29 patients, reinfusion was applied in more than 1 day because of the high volume of stem cell product. We did not see any dimethyl sulfoxide toxicity, cardiac arrhythmia, or volume overload complications. Hypertensive attacks during infusion were easily controlled by furosemide treatment. In the group with multiple infusions, the infused CD34+ cell numbers had a mean of (4.8±2.8)x106/kg, and in the single infusion group the mean was (8.1±5.5)x106/kg. There were no statistical differences between the two groups regarding platelet and neutrophil engraftment days (p=0.850, r=0.820 and p=0.500, r=0.440). There was no statistical difference between the two groups for hospitalization days (p=0.060, r=0.050). Conclusion: In cases with a high volume of stem cell product to acquire adequate stem cells, reinfusion can be safely applied across multiple days without any delay in engraftment

Clinical outcomes and treatment patterns of primary central nervous system lymphoma: Multicenter retrospective analysis

Objectives: Primary central nervous system lymphoma (PCNSL) is a rare malignant disease with poor prognosis. Its low incidence leads to challenges in decision-making for treatment. As a matter of fact, there is still no consensus on the appropriate treatment modalities. In this context, the objective of this study is to investigate and comparatively assess the efficacies of several treatment modalities in the treatment of PCNSL. Methods: Thirty-four patients diagnosed with PCNSL at 5 different hematology centers between 2007 and 2021 were included in the study. Patients’ data from all five centers were collected retrospectively. Since ibrutinib is not approved for this indication in Turkey, consent for off-label use of ibrutinib is obtained from each patient. Ethics committee ap-proval was obtained on June 9, 2021 with decision number 2021/18-05. Results: The median age of the patients was 59 (min.: 22, max.: 78) years. The male-to-female ratio was 1.26/1. Nineteen (55.9%) patients had Eastern Cooperative Oncology Group (ECOG) performance score of ≥2. Fifteen (44.1%) patients had normal lactate dehydrogenase (LDH) levels and only 14.7% of the patients had B symptoms at the time of diagnosis. Magnetic resonance imaging (MRI) revealed a single mass lesion in 14 (41.2%) patients. As an induction therapy, meth-otrexate-based regimen was administered in 29 (85.3%) patients. Only 14 of the 34 patients received 4 or more cycles of high-dose methotrexate (MTX). About 32.4% of the patients received radiation therapy (RT) during follow-up as a part of induction therapy. Five patients received only RT due to poor performance status. Ibrutinib was administered in 5 patients for refractory disease. It was determined that four or more cycles of MTX treatment increased progression-free survival (PFS) (p=0.031) and overall survival (OS) (p=0.012). Moreover, RT improved PFS (p=0.023). Considering that the complete response achieved by induction therapy influences long-term survival, achievement of the best response to the treatment regimens administered in combination with new agents may prolong survival (PFS: p=0.01, OS: p=0.023). Conclusion: The findings of this study indicate that the initial response to treatment is crucial. Additionally, it was found that high-dose MTX treatment should be administered for 4 cycles or more in order to achieve the best results. Furthermore, it was determined that ibrutinib monotherapy was well-tolerated in our patients with relapsed/refractory disease, with excellent clinical benefits. In conclusion, a combination therapy consisting of high-dose MTX, ibrutinib, and rituximab appears to be a promising initial treatment approach in appropriate patients
