RESUMEN

BACKGROUND: No adequate data exist on the impact of multiple myeloma (MM) with extramedullary disease (EMD) after autograft and maintenance therapy. METHODS: We identified 808 patients with newly diagnosed MM who received first autograft, of whom 107 had EMD (83 paraskeletal and 24 organ involvement), and who had been reported to the EBMT registry December 2018. Distribution according to type of involvement was similar between the treatment groups (p = .69). For EMD, 46 (40%) received thalidomide, 59 (51%) lenalidomide, and 11 (10%) bortezomib. RESULTS: The median follow-up from maintenance start was 44 months. Three-year progression-free survival (PFS) was 52% (48%-57%) for no EMD, 56% (44%-69%) for paraskeletal involvement, and 45% (22%-68%) for organ involvement (p = .146). Early PFS (within first year) appeared to be significantly worse for organ involvement (hazard ratio, 3.40), while no significant influence was found after first year from maintenance start. Three-year overall survival (OS) was 81% (77%-84%), 88% (80%-96%), and 68% (47%-89%; p = .064), respectively. With thalidomide as reference, lenalidomide was significantly associated with better PFS and OS, whereas bortezomib appeared to improve outcome specifically in EMD. CONCLUSION: Lenalidomide maintenance is standard of care for MM without EMD, whereas extramedullary organ involvement remains a significant risk factor for worse outcome, especially for early events after maintenance start.

RESUMEN

Aim: To determine the unmet needs and challenges in management, diagnosis, treatment, follow-up and patient-physician communication in acute leukemia (AL). Materials & methods: The study was based on a modified Delphi approach. A questionnaire including the major potential obstacles was circulated twice among 13 hematologists. Results: The obstacles in AL management were limited access to the novel treatments and genetic tests, limited bed capacity, insufficient level of knowledge among allied health personnel, limited availability of psycho-oncological support and low levels of awareness in the population about the importance of stem cell donation. Conclusion: The challenges in the management of AL are critical to guide the efforts to improve the quality of healthcare delivery and the evidence-based decision making at treatment of AL patients.

RESUMEN

Evans syndrome is a rare condition characterized by simultaneous or sequential development of autoimmune hemolytic anemia and immune thrombocytopenia (and/or immune neutropenia). Coronavirus disease 2019 (COVID-19) may cause various hematologic conditions, such as coagulation abnormalities (e.g., bleeding or thrombosis) or cell count alterations (e.g., lymphopenia and neutrophilia). COVID-19 may also induce Evans syndrome via immune mechanisms. Here, we describe the case of a patient developing Evans syndrome shortly after COVID-19 infection. Immune thrombocytopenia and warm-type autoimmune hemolytic anemia developed simultaneously, and intravenous immunoglobulin and methylprednisolone were initially administered. Additionally, we intend to review all COVID-19-induced Evans syndrome cases currently present in the literature and emphasize the differences as well as the similarities regarding patient characteristics, relationship to COVID-19 infection, and treatment approach. Since autoimmune cytopenias are frequent in COVID-19 patients, clinicians should pay particular attention to profound and abrupt-onset cytopenias. In these circumstances, hemolysis markers such as lactate dehydrogenase, haptoglobulin, Coombs tests, etc. should be investigated, and the possibility of Evans syndrome should always be considered to ensure prompt and appropriate treatment. These factors are essential to ensure hematologic recovery and prevent complications such as thrombosis.

RESUMEN

The diabetic fot/ulcer is the cause of high morbidity and mortality in patients with diabetes mellitus (DM). Generally, medical treatment of diabetic foot/ulcer is ineffective and stem cell implantation is an important option in the treatment. Here, we present a 69 years old man admitted to hospital due to a 3 × 4 cm wound in the plantar surface of left foot. Autologous stem cells were applied intralesionally into diabetic ulcers. The lesion shrunken 50 % at the 16th week and there is a wound under the left foot at 32nd week. Intralesionally autologous stem cell application was useful and safe without adverse course in patients with diabetic foot/ulcer.

RESUMEN

Autologous hematopoietic cell transplantation (AHCT) is an established treatment option for adult patients presenting with multiple myeloma (MM), Hodgkin lymphoma (HL) and various subtypes of non-Hodgkin lymphoma (NHL) in upfront and/or relapsed/refractory disease settings. Although there are recently published consensus guidelines addressing critical issues regarding autologous hematopoietic progenitor cell mobilization (HPCM), mobilization strategies of transplant centers show high variability in terms of routine practice. In order to understand the current institutional policies regarding HPCM in Turkey and to obtain the required basic data for preparation of a national positional statement on this issue, Turkish Hematology Research and Education Group (ThREG) conducted a web-based HPCM survey. The survey was designed to include multiple-choice questions regarding institutional practice of HPCM in adults presenting MM, HL, and NHL. The representatives of 27 adult HCT centers participated to the study. Here we report the results of this survey shedding light on the real-world experience in Turkey in terms of autologous HPCM mobilization strategies in patients presenting with MM and lymphoma.

RESUMEN

Malignant diseases occurring in elderly patients follow a different course from younger patients and show different genetic structures. Therefore, in this retrospective study, the somatic gene variant profile and fusion gene profiles of elderly and young acute leukemia patients were determined to draw attention to the existing genetic difference, and the results were compared. In this study, the records of 204 acute leukemia patients aged 18+ who were referred to the Molecular Pathology Laboratory from the Hematology Clinic between 2018 and 2022 were reviewed retrospectively. Fusion gene detection in patients was performed with the HemaVision®-28Q Panel. The NGS Myeloid Neoplasms Panel was conducted using the MiniSEQ NGS platform according to the manufacturer's protocol. When all cases are evaluated together, the most frequently diagnosed acute leukemia is acute myeloid leukemia (85.8%). Both groups had a similar fusion gene profile; however, the fusion burden was higher in the elderly group. When the groups were evaluated in terms of somatic gene variations, there were differences between the groups, and the variation load was higher in the elderly group. Considering the different somatic gene variation profiles, it is understood that the genetic structure of tumor cells is different in elderly patients compared to young cases.

RESUMEN

OBJECTIVE: Fertility preservation stands before us as an issue of quality of life for cancer patients and their partners and families. Therefore, the object of the present study was to determine the extent of the knowledge that hematologists have about fertility preservation and to understand their attitudes and practices regarding this matter. MATERIALS AND METHODS: A total of 25 hematologists participated in a survey. The questionnaire included questions on sociodemographic characteristics and awareness concerning the subject of fertility preservation, as well as questions designed to determine the extent of the knowledge that hematologists had on the subject and to understand their attitudes and practices in this context. RESULTS: Of the participants in the study, all expressed their awareness of the adverse effects that the various treatments they were prescribing could have on fertility; 2 (8%) revealed that they had never heard of the concept of fertility preservation. Of the participants, 19 (76%) indicated that they did not have adequate knowledge about fertility preservation, but 22 (88%) fortunately expressed a need for acquiring more knowledge about the subject. Of the respondents, 23 (92%) said that they did not have any brochures or published resources on this subject and stated their belief that if hematologists did have such documents, they would have more opportunity to discuss the various fertility preservation options with patients. All of the participants in the survey supported the idea of the Turkish Society of Hematology publishing a guidebook on this subject and organizing a session on fertility preservation in their regular congress. CONCLUSION: Meeting the needs of hematologists for training and knowledge in the subject of fertility preservation and ensuring the development of appropriate attitudes and practices in this area is an important issue. The Turkish Society of Hematology may play a significant key role. CONFLICT OF INTEREST: None declared.

RESUMEN

OBJECTIVE: Diffuse large B cell lymphoma (DLBCL) is the most common type of non-Hodgkin lymphoma. Although it is a clinically and biologically heterogeneous disease, it is usually treated with R-CHOP chemotherapy. Here, we aimed to investigate gene expression frequency with next-generation sequencing (NGS) and the relation of gene mutations with remission and relapse status in patients with DLBCLs. MATERIALS AND METHODS: We investigated gene mutation profiles by NGS in patients with DLBCL-NOS and analyzed the correlation between gene mutations and response and relapse rates and other clinical indices. RESULTS: Twenty-eight of forty patients were evaluated. The most commonly mutated genes were ANKRD, BRCA1, BRCA2, EZH2, KMTC2, MYC, MYD88, NF1, NOTCH1, PMS2, PTEN, and WRN. The relapse rate was found higher in DLBCL patients with ANKRD26, BRCA2, MYD88, and NOTCH1 mutations. Also, remission duration was found shorter in patients with ANKRD26, BRCA2, and MYD88 mutations. CONCLUSIONS: Our study demonstrates that the presence of some genetic mutations is effective on prognosis in patients with DLBCL. NGS-based evaluation of DLBCL treatment can be used in the future.

RESUMEN

Objective: This study was undertaken to evaluate the long-term clinical efficacy of epoetin alfa and darbepoetin alfa in patients with myelodysplastic syndrome (MDS) in a real-life setting. Materials and Methods: A total of 204 patients with low-risk or intermediate-1-risk MDS who received epoetin alfa or darbepoetin alfa were included. Hemoglobin levels and transfusion needs were recorded before treatment and at 12 months, 24 months, 36 months, and 48 months of treatment. Results: At the 36-month (p=0.025) and 48-month (p=0.022) visits, epoetin alfa yielded significantly higher hemoglobin levels compared to darbepoetin alfa. Transfusion needs were also significantly lower with epoetin alfa compared to darbepoetin alfa at 24 months (p=0.012) and in the low-risk group compared to the intermediate-risk group at 24 months (p=0.018), 36 months (p=0.025), and 48 months (p<0.001). Treatment response rates at the 24-month, 36-month, and 48-month visits in the epoetin alfa (43.0%, 33.6%, and 27.1%), darbepoetin alfa (29.9%, 22.7%, and 16.5%), low-risk (39.3%, 30.0%, and 26.0%), and intermediate-risk (29.6%, 24.1%, and 11.1%) groups were lower than those obtained at 12 months, and the values differed significantly for the 36-month and 48-month visits with values ranging from p<0.05 to p<0.001. Conclusion: This real-life long-term ESA extension study investigated the clinical efficacy of epoetin alfa and darbepoetin alfa for up to 48 months, revealing that treatment efficacy reached a plateau starting from the 24th month of therapy with a continuing decrease in treatment response rates regardless of treatment type, risk status, or gender. Nonetheless, significantly higher hemoglobin levels and marked improvement in transfusion needs were evident in epoetin-treated patients compared to darbepoetin-treated patients and in the low-risk group compared to the intermediate-risk group.

RESUMEN

The number of patients of reproductive age diagnosed with various malignant hematological diseases increases every year. These patients undergo chemotherapy, radiotherapy, and various other treatments that may have gonadotoxic effects. The life expectancy of these patients is increasing rapidly due to the variety of treatment options. As such, an increasing number of patients-as well as their parents and spouses-express their concerns about the patient's fertility post treatment. In the present review it was aimed to provide an overview of current fertility-preserving treatment options and the future of fertility preservation.

RESUMEN

This study aimed to evaluate the clinical efficacy of epoetin alfa and darbepoetin alfa in patients with myelodysplastic syndromes (MDS) in the real-life setting. A total of 204 patients with low-risk or intermediate-1-risk MDS who received epoetin alfa or darbepoetin alfa were included. Hemoglobin levels and transfusion need were recorded before and during 12-month treatment. Hemoglobin levels were significantly higher at each follow up visit when compared to baseline levels in both epoetin alfa (mean ± SD 8.68 ± 1.0 g/dL at baseline vs. 9.83 ± 1.45, 9.99 ± 1.55, 10.24 ± 1.77 and 10.2 ± 1.5 g/dL, respectively) and darbepoetin alfa (8.83 ± 1.09 g/dL at baseline vs. 9.62 ± 1.37, 9.78 ± 1.49, 9.9 ± 1.39 and 10.1 ± 1.5 g/dL, respectively) groups (p < 0.001 for each). Transfusion need significantly decreased from baseline at each study visit in the epoetin alfa group (p < 0.001) and only at the 12th month visit (p < 0.001) in the darbepoetin alfa group. Hemoglobin levels or transfusion need was similar between treatment groups. Overall, 12-month response rate was 58.1% for epoetin alfa and 41.9% for darbepoetin alfa, with no significant difference between treatment groups, whereas higher response rate was noted within the first three months (62.7%) compared to next 9 months (ranged 44.4-60%) of treatment in the epoetin alfa group (p ranged 0.002 to < 0.001). This real-life retrospective study revealed similar efficacy of epoetin alfa and darbepoetin alfa among low risk or intermediate-1 risk MDS patients with no difference in treatment response between treatment groups, whereas a likelihood of earlier treatment response in the epoetin alfa group.

RESUMEN

BACKGROUND: The demographic characteristics, performance status, frequency of comorbidities and survival rate of patients with multiple myeloma (MM) show variability geographically and different risk scoring systems have been used to assess this population. Here, we present data from a Turkish cohort, focusing on identifying similarities and differences, relative to other reports in the literature. RESEARCH DESIGN AND METHODS: A total of 310 patients diagnosed with MM were enrolled. Their demographic characteristics were investigated retrospectively. For performance assessment; the ECOG-IMWG Myeloma Frailty Score, R-MCI and HCT-SCI scoring indexes were used. PFS and OS periods, as well as the causes of deaths, were determined. RESULTS: The mean age of all study participants was 65 ± 10 years. The mean PFS and OS periods were 24.14± 26.11 and 65.3 ± 4.4 months, respectively. The median R-MCI, CCI and HCT-CI scores were five, four and three points, respectively. Myeloma-related complications were the leading cause of death, with a frequency of 51%. CONCLUSION: Among the scoring systems utilised, R-MCI was more convenient to apply due to its ease of use and practicality. Our study supports the heterogeneous course of myeloma and highlights geographic differences including comorbidities, causes of death and overall survival.

RESUMEN

OBJECTIVE: High-dose ascorbic acid leads to the formation of highly reactive oxygen species due to the pro-oxidant effect, resulting in cell death; therefore, used as an additive treatment in several malignancies. We present the results obtained by administration of pharmacological dose of ascorbic acid to conventional chemotherapy in relapsed refractory multiple myeloma patients. MATERIALS-METHODS: Intravenous ascorbic acid at a pharmacologic dose of 15 gram/week was added to the chemotherapy regimen of relapsed refractory multiple myeloma patients, who received carfilzomib-lenalidomide-dexamethasone treatment and did not respond after the second cycle. RESULTS: The total of 4 patients who had previously received 6-9 lines of myeloma treatment were included. After 4 cycles of chemotherapy + ascorbic acid combination, 1 patient had a complete response whereas other patients had a very good partial response. CONCLUSION: The addition of pharmacological dose ascorbic acid to conventional chemotherapy can be an effective approach in relapsed refractory patients. Clinical studies with a large number of patients will be useful to evaluate the pharmacological dose of ascorbate in plasma cell disorders.

RESUMEN

Objective: Lenalidomide is an effective immunomodulatory derivative drug used in the treatment of multiple myeloma (MM). It is available in original and generic forms in Turkey, but there is no clinical study that has compared the effectiveness and adverse events (AEs) of the generic and original forms of lenalidomide. We compared the effectivity and AEs of generic and original lenalidomide in patients with relapsed/refractory MM (RRMM). Materials and Methods: Patients with RRMM using original or generic lenalidomide were evaluated retrospectively. Overall response (OR), complete response (CR), very good partial response (VGPR), partial response (PR), stable disease, and progressive disease rates and hematologic and nonhematologic AEs were evaluated in these RRMM patients. The results were described as numbers, frequencies, and percentages and were analyzed using PASW 19.0 for Windows with chi-square and Fisher exact tests. Results: The number of patients using original lenalidomide was 55 and the number of patients using generic lenalidomide was 43. The OR rate was 67.2% for patients using original lenalidomide and 60.4% for those on generic lenalidomide. CR and VGPR rates were 14.5% and 45.4% in the original group while the CR and VGPR rates were 20.9% and 18.6%, respectively, in patients using generic lenalidomide. Hematologic AEs were similar in the two groups while some nonhematologic AEs were less common in the original lenalidomide group than the generic group. Only pyrexia as a grade 3-4 AE was more common in the original lenalidomide than the generic lenalidomide group. Conclusion: This study showed that the generic form of lenalidomide has similar efficacy with the original form of lenalidomide in the treatment of RRMM. The AEs of original lenalidomide were generally fewer than those of generic lenalidomide. Further studies involving a larger number of patients with RRMM would be useful for comparing the efficacy and AEs of original and generic lenalidomide.

RESUMEN

We retrospectively evaluated the use of gemtuzumab ozogamicin (GO) in relapsed refractory (R/R) acute myeloid leukemia (AML) patients. Twenty-one CD33 positive R/R AML patients who received GO as a single agent in 4 hematology centers were included in this study. The median age was 59, and the median ECOG performance score was 2. According to cytogenetic analysis, 1 patient had favorable risk, 12 patients with intermediate, and 8 patients with adverse risk. The overall response rate was 52.3%. Partial response was achieved in 3 of 8 patients with adverse risk. 33.3% of patients developed grade 3 anemia. Grade 4 neutropenia and thrombocytopenia were observed in 80% of the patients. One of the patients died due to sinusoidal obstruction syndrome / veno-occlusive disease (SOS / VOD) due to GO side effects. GO may be considered as a good option for salvage therapy in R/R AML patients.
