Gemcitabine and treatment of diffuse large B-cell lymphoma in relapsed or refractory elderly patients: A prospective randomized trial in Algeria

Context: Support for non-Hodgkin\u2032s lymphoma (NHL) with large cells that is refractory or relapsed after first-line chemotherapy poses a greater therapeutic problem with bone marrow transplant therapy or when old age is a contra-indication for high-dose chemotherapy, especially among developing countries such as Algeria. Aim: To show that the regimen, including gemcitabine, could be more effective in treating elderly patients with diffuse large B-cell lymphoma (DLBCL) in relapse / refractory, without complete remission, when compared with the ESHAP (etoposide, cisplatine, solumedrol, aracytine) regimen. Materials and Methods: Ninety-six patients in the age group of 60-70 years were volunteers for a prospective randomized single-blind study, carried out for three years. Patients were divided into two groups by the drawing of lots. The first group (GA, n = 48, relapse; n = 27 [56.3%], refractory; n = 21 [43.7%]) received treatment with ESHAP protocol and the second one (GB, n = 48, relapse; n = 28 [58%], refractory; n = 20 [42%]) with GPD (gemcitabine, dexamethasone, cisplatine) protocol. Results: The overall response rates and mean survival at three years were significantly higher among patients subjected to GPD treatment compared with those subjected to ESHAP treatment (63% vs. 55%, P = 0.01 and 20.5% [95% CI 16.5-24.5] vs. 11.8% [8.9-14.6], respectively). Additionally, three-year progression-free and event-free survival rates were 20.5% (16.3-24) and 19.7% (15.9-23.5), respectively, for the GPD regimen and 10.9% (8.2-13.7) and 11.1% (95% CI 8.5-13.7), respectively, for the ESHAP regimen. Moreover, the GPD regimen was associated with improving overall survival (RR=2.02, 95% CI 1.59-2.56; P = 0.000), event-free survival (2.03, 1.64-2.52; P < 0.001) and progression-free survival (1.86, 1.46-2.37; P < 0.001). Conclusion: In cases of contra-indication for high-dose chemotherapy for elderly patients with DLBCL, without complete remission, the Gemcitabine-based therapy protocol represents a more effective and less toxic than that of ESHAP

Publisher Copyright: © 2018 The AuthorsMultiple myeloma (MM) remains an incurable disease, with little information available on its management in real-world clinical practice. The results of the present prospective, noninterventional observational study revealed great diversity in the treatment regimens used to treat MM. Our results also provide data to inform health economic, pharmacoepidemiologic, and outcomes research, providing a framework for the design of protocols to improve the outcomes of patients with MM. Background: The present prospective, multinational, noninterventional study aimed to document and describe real-world treatment regimens and disease progression in multiple myeloma (MM) patients. Patients and Methods: Adult patients initiating any new MM therapy from October 2010 to October 2012 were eligible. A multistage patient/site recruitment model was applied to minimize the selection bias; enrollment was stratified by country, region, and practice type. The patient medical and disease features, treatment history, and remission status were recorded at baseline, and prospective data on treatment, efficacy, and safety were collected electronically every 3 months. Results: A total of 2358 patients were enrolled. Of these patients, 775 and 1583 did and did not undergo stem cell transplantation (SCT) at any time during treatment, respectively. Of the patients in the SCT and non-SCT groups, 49%, 21%, 14%, and 15% and 57%, 20%, 12% and 10% were enrolled at treatment line 1, 2, 3, and ≥ 4, respectively. In the SCT and non-SCT groups, 45% and 54% of the patients had received bortezomib-based therapy without thalidomide/lenalidomide, 12% and 18% had received thalidomide/lenalidomide-based therapy without bortezomib, and 30% and 4% had received bortezomib plus thalidomide/lenalidomide-based therapy as frontline treatment, respectively. The corresponding proportions of SCT and non-SCT patients in lines 2, 3, and ≥ 4 were 45% and 37%, 30% and 37%, and 12% and 3%, 33% and 27%, 35% and 32%, and 8% and 2%, and 27% and 27%, 27% and 23%, and 6% and 4%, respectively. In the SCT and non-SCT patients, the overall response rate was 86% to 97% and 64% to 85% in line 1, 74% to 78% and 59% to 68% in line 2, 55% to 83% and 48% to 60% in line 3, and 49% to 65% and 36% and 45% in line 4, respectively, for regimens that included bortezomib and/or thalidomide/lenalidomide. Conclusion: The results of our prospective study have revealed great diversity in the treatment regimens used to manage MM in real-life practice. This diversity was linked to factors such as novel agent accessibility and evolving treatment recommendations. Our results provide insight into associated clinical benefits.publishersversionPeer reviewe

The autographt of non-cryopreserved hematopoietic stem cells , an example of clinical research allowing more value in care: the experience of EHU 1st November of Oran

Hematopoietic stem cell autograft (HSC) is a therapeutic technique, allowing the patient’s stem cells to be used to get around the pitfall of severe aplasia after chemotherapy. Its very high cost price made it inaccessible in many countries and in particular in Africa where there are only six countries with 16 centers compared to 679 in Europe, which represents a deficit of 98%. In Algeria, the first cell transplant was performed in 1998 at the Algiers CPMC. The 2nd transplant center was created in 2009 at the EHU 1st November in Oran and became a national transplant center. We present in this work, the progress of the implementation of the cell transplant procedure in Oran, according to international recommendations and their adaptations according to local working conditions

Mutation resistant to tyrosine kinase inhibitors in chronic myeloid leukemia : about a case

Introduction - The management and long-term outcome of patients affected by chronic myeloid leukemia (CML) hadimproved considerably with the introduction in the 2000’s of tyrosine kinase inhibitors, that revolutionized the prognosis of the disease and improved overall the survival of patients. However, failures are observed. The appearance of mutations in the tyrosine kinase domain of BCR-ABL1 protein constitutes an important cause of resistanceto therapy and represents the most studied mechanism.Observation - Here, we report a 20 years old patient diagnosed in 2015 and followed for chronic myeloid leukemia in chronic phase. His biological monitoring was marked by primary resistance to tyrosine kinase inhibitors of 1st and 2nd generation (Imatinib, Dasatinib and Nilotinib)

Can Sex Be Determined from a Blood Smear?

Objective: Originally, this blind study was designed to check whether blood smears constitute reliable tools to determine sex. However, when we analyzed our data some interesting findings immerged and in this paper we try to highlight them. Material and Methods: 74 blood smears (35 women and 39 men) have been performed and then stained. 200 polynuclearneutrophils were examined for nuclear appendages and classified into four groups: neutrophils with form A, B or C appendages and neutrophils without any appendage.The difference (A-C) was calculated for each slide. The “cytologic sex” was defined as a male in case of a negative value and as a female otherwise. Results: Neutrophils bear the same amount of appendages in both genders (p=0.37). But the number of form A is greater in females (p<0.0001) and form C is much more frequent in males (p<0.0001), that is why, the difference A-C is the best way to differentiate between both sexes.The distribution histogram of A-C in women shows a multimodal histogram contrary to men’s graphwhich is a bell-shaped curve. The menstrual cycle was incriminated in this feature. Conclusion: Blood smear is a reliable tool to determine gender

Frequency of BCR-ABL 1 Fusion Transcripts Variants in Chronic Myeloid Leukemia Algerian patients

Aim - In chronic myeloid leukemia (CML), the research of BCR-ABL1 fusion transcript became essential to confirm the molecular diagnosis. In this study, we describe the different types of BCR-ABL1 fusion transcripts found in CML patients in West Algerian patients.Methods - A total of 167 CML suspected patients were included in our study. A qualitative research on fusion transcripts was carried out by reverse transcription polymerase chain reaction (RT-PCR) technique in the biochemistry laboratory of Oran’s university hospital establishment.Results. The two types of major BCR-ABL1 fusion transcript Mb3a2 and Mb2a2 were present in 59,8 % and 36,4% of cases respectively. Two patients (1,8%) had an atypical and rare transcript type e19a2 and two others (1,8%) co-expressed b3a2 and b2a2 transcript types. Conclusion - Our study confirmed the data in the literature with a higher incidence of the major transcript
