RESUMO
INTRODUCTION: Cyclosporine-A (CsA) and post transplantation cyclophosphamide (PTCy) are common agents used for graft versus host disease (GVHD) prophylaxis in Haploidentical hematopoietic cell transplantation (haplo-HCT). However, the impact of CsA cessation timing in the posttransplant setting on clinical outcomes is uncertain. We aimed to investigate the impact of a novel approach that integrated early CsA cessation with PTCy utilization. PATIENTS AND METHODS: This study was a single arm retrospective study carried out at a tertiary referral hospital hematology and bone marrow transplantation center between 2009 and 2022. The patients who received haplo-HCT with ATG, PTCy and CsA as GVHD prophylaxis were included. CsA was planned for cessation starting at day 45 to day 60. Acute and chronic GVHD were evaluated and graded. CsA blood concentrations and its impact on acute and chronic GVHD was evaluated. RESULTS: Thirty-one patients composed of 19 (61.3%) male and 12 (38.7%) female patients with a median age of 31 years (20-58). Busulfan and TBI based conditioning regimens were the most utilized regimens. The majority of donors were first degree relatives. Stem cell origin was peripheral blood for all patients. GVHD prophylaxis consisted of ATG, CsA and PTCy. Acute GVHD was observed in 9 (29%) cases, whereas chronic GVHD was seen in 3 (9.7%) cases, with 2 of them having overlapping GVHD. Age, gender, number of chemotherapy lines, transplant characteristics, infused CD34 cell count, and engraftment durations were similar among patients with and without GVHD. Patients with GVHD had similar 1st, 2nd, 3rd and 4th week CsA concentrations compared to patients without GVHD (p > 0.05). The presence of GVHD was not associated with worse progression free survival and overall survival (p = 0.6, p = 0.5, respectively). CMV reactivation was more common in the GVHD group. CONCLUSION: In the current study, we did not find an impact of CsA concentration on GVHD and post-transplant outcomes in Haplo-HCT setting. Therefore, together with the use of PTCy, early CsA cessation can be an option; further studies are needed to understand all aspects of this approach.

INTRODUCTION: Peripheral blood stem cells (PBSC) mobilization with granulocyte colony stimulating factor (G-CSF) for healthy donors is generally performed at 5th day. However, earlier collection is sometimes feasible, raising the question of whether to initiate apheresis early to limit further G-CSF exposure, while considering the risk of mobilization failure. In the current study, we examined the factors predicting successful 4th day collection and developed a model that can be used practically. PATIENTS AND METHODS: The study was carried out by obtaining the data of PBSC mobilizations performed between January 2009 and September 2022 in our transplantation center. RESULTS: A total of 141 healthy donors with a median donor age of 32 (18-64) were included. Adequate mobilization was achieved in 115 (81.6 %) patients. Median peripheral CD34 + cell count was 69.4/µL in the adequate mobilization group and 46/µL in the mobilization failure group (p < 0001). Multivariate analysis revealed that donor/recipient weight ratio and the 4th day peripheral CD34 + cell count≥ 50/µL were independent markers for 4th day collection success. A predictive model of our center including these parameters was available with 0.765 sensitivity and 0.968 specificity [(AUC):0.948 (95 % CI, 0.90-0.99), p < 0.001]. CONCLUSION: The result of the current study shows that peripheral 4th day collection can be performed in selected donors, taking into account peripheral CD34+ cell count and donor/recipient weight ratio. In addition, using these indicators, new predictive models can be created that may assist clinicians in daily practice.

Therapeutic apheresis is an extracorporeal treatment that selectively removes abnormal cells or harmful substances in the blood that are associated with or cause certain diseases. During the last decades the application of therapeutic apheresis has expanded to a broad spectrum of hematological and non-hematological diseases due to various studies on the clinical efficacy of this procedure. In this context there are more than 30 centers performing therapeutic apheresis and registered in the apheresis database in Turkey. Herein, we, The Turkish Apheresis Registry, aimed to analyze some key articles published so far from Turkey regarding the use of apheresis for various indications.

INTRODUCTION: The most common kind of leukemia in adults is chronic lymphocytic leukemia (CLL). CLL is treated with ibrutinib. During the course of ibrutinib therapy, bleeding and cardiac arrhythmias may occur. Non-hemorrhagic adverse events are extremely infrequent in individuals using ibrutinib. CASE REPORT: A 64 year-old man was diagnosed with CLL in June 2016. He was treated with 6 courses of FCR, he stayed in remission for 3 years and then relapsed. He achieved partial remission after two months of therapy with ibrutinib. The patient was admitted to the hospital with fever and shortness of breath. Pericardial tamponade and effusion was diagnosed during his evaluation. MANAGEMENT & OUTCOME: Non-hemorrhagic exudative effusion was drained by pericardiocentesis and a pericardial catheter was inserted to drain pericardial effusion. In all pleural and pericardial effusion samples, pathological and flow cytometric examination revealed no atypical malignant cells for malignancy, including CLL. Infections, both bacterial and viral, were also undetectable in the samples, as were rheumatological markers of collagen vascular disease. Ibrutinib therapy was discontinued. The pericardial effusion and tamponade were linked to ibrutinib treatment after evaluating the adverse drug reaction probability scale with a total score of 6. Colchicine was administered to reduce the pericardial effusion. The catheter was removed; pericardial effusion did not reoccur during follow up visits. DISCUSSION: Serious adverse events of ibrutinib are seen when treating CLL patients. This group of individuals should be closely monitored for potentially serious complications such as pericardial effusion and cardiac tamponade.

INTRODUCTION: Graft-versus-host disease (GVHD) is a common complication of allogeneic hematopoietic cell transplantation (HCT). In the treatment of chronic GVHD, skin directed therapy, systemic corticosteroids, calcineurin inhibitors (such as cyclosporine (CsA) and tacrolimus), rituximab, mycophenolate mofetil (MMF), extracorporeal photopheresis (ECP) and ruxolitinib are used. CASE REPORT: We present an 18 year old male with Philadelphia chromosome positive acute B lymphoblastic leukemia, treated with allogeneic HCT from a full matched sibling donor. The patient had grade 2 chronic cutaneous GVHD resistant to corticosteroids, CsA, MMF, and ECP treatment. Three months after initiation of ruxolitinib therapy, the patient developed skin ulcers on his lower extremities. MANAGEMENT & OUTCOME: The biopsy revealed that the changes were caused by the drug reactions. We suspected ruxolitinib as the likely cause of these ulcerative lesions after evaluating the adverse drug reaction probability scale. The adverse drug score was 4, therefore, ruxolitinib treatment was discontinued. Ulcerative lesions fully recovered after 4 weeks of follow-up. DISCUSSION: Ruxolitinib is used in the treatment of chronic GVHD that has been resistant to steroids and other salvage therapies. In our case, ruxolitinib was used as a salvage therapy in a patient who had refractory chronic skin GVHD. Ruxolitinib-related skin lesions with ulcers of lower extremities and whole body erythematous skin lesions were reported previously in patients with myelofibrosis. The pathophysiology of ruxolitinib related skin ulcers is unknown. Skin changes of patients using ruxolitinib should be closely monitored, and newly developing lesions should be suspected of being drug-related and biopsied.

The AETHERA trial reported an increased progression-free survival (PFS) when brentuximab vedotin (BV) was used as maintenance therapy in high-risk Hodgkin lymphoma (HL) after autologous stem cell transplantation (ASCT). Thus, we aimed to determine the impact and safety of BV as maintenance after ASCT in real-world patients. Seventy-five patients with relapsed/refractory HL started on BV consolidation therapy after ASCT due to high risk of relapse, between January 2016 and July 2019, from 25 institutions, were included in the study. The median follow-up time was 26 months. The most common high-risk features were primary refractory or relapsed disease <12 months (n = 61), lack of complete response (CR) to the last salvage regimen (n = 51), and having had at least two salvage regimens (n = 29). At the time of analysis, 42 patients completed consolidation courses, and BV was discontinued in 33 patients. Fifty patients had an ongoing response (CR in 41, PR in 6, and SD in 3 patients), 25 had progressed. Ten died in the follow-up, eight with progressive disease and two due to infection while in CR. The 2-year PFS and OS rates were 67.75% (95% confidence interval [CI]: 0.55-0.77) and 87.61% (95% CI: 0.76-0.94), respectively. Seventeen patients (23%) received BV in the pre-ASCT treatment lines, and there was no survival difference between the BV-naïve and BV-exposed groups. The most common adverse events were neutropenia (27%) and peripheral neuropathy (21%). Sixteen patients (21.3%) experienced grade 3 or 4 toxicity. BV was discontinued due to adverse event in 12 patients. Consolidation with BV after ASCT can achieve a 2-year PFS of 67.75% (95% CI: 0.55-0.75) with an acceptable toxicity profile.

BACKGROUND: Autologous stem cell transplantation (ASCT) after induction treatment is the standard of care. Our understanding of myeloma genetics has been very limited and its effect to stem cell mobilization is not widely investigated. We aimed to investigate the effect of genetic abnormalities on stem cell mobilization in myeloma. METHODS: The data of 150 MM patients who underwent stem cell mobilization at our center between 2009-2020 were included and analyzed retrospectively. Pre-treatment bone marrow cytogenetics and fluorescence in situ hybridization tests were performed for each patient. RESULTS: Groups were divided into two as patients with normal cytogenetic and abnormal cytogenetic. No difference observed between groups regarding age, gender and ECOG (p = 0.4; p = 0.2; p = 0.3). Groups were similar concerning myeloma characteristics, received treatment and treatment response. Median CD34+ cells/kg harvested was 444(2-11.29) in normal cytogenetic group whereas it was 4,8(2.4-8.6) in abnormal cytogenetic group(p = 0.2). Optimal CD34+ cells level achievement was 73 (67 %) in normal cytogenetic group while it was 25(71.4 %) in abnormal cytogenetic group(p = 0.6). Neutrophil and platelet engraftment durations were similar among cytogenetic groups (p = 0.7; p = 0.9). R-ISS based groups were also did not differ regarding harvested CD34+ cells and achievement optimal CD34 level (p = 0.79, p = 0.74). Engraftment durations for neutrophil and platelet were comparable between R-ISS based groups (p = 0.59, p = 0.65) CONCLUSIONS: Here we were not able to find any impact of genetic abnormalities on stem cell mobilization in myeloma patients. Expanded studies can aid to identify the effect of particular genetic anomalies on the stem cell mobilization.

SARS-CoV-2 attaches to the angiotensin-converting enzyme 2 (ACE-2) receptor on human cells. The virus causes hypercytokinemia, capillary leak, pulmonary edema, acute respiratory distress syndrome, acute cardiac injury, and leads to death. Mesenchymal stem cells (MSCs) are ACE-2 negative cells; therefore, can escape from SARS-CoV-2. MSCs prevent hypercytokinemia and help the resolution of the pulmonary edema and other damages occurred during the course of COVID-19. In addition, MSCs enhance the regeneration of the lung and other tissues affected by SARS-CoV-2. The case series reported beneficial effect of MSCs in COVID-19 treatment. However, there are some concerns about the safety of MSCs, particularly referring to the increased risk of disseminated intravascular coagulation, and thromboembolism due to the expression of TF/CD142. Prospective, randomized, large scale studies are needed to reveal the optimum dose, administration way, time, efficacy, and safety of MSCs in the COVID-19 treatment.

INTRODUCTION: Allogeneic stem cell transplantation (Allo-SCT) is a well-established treatment option for hematological malignancies. With the introduction of reduced-intensity conditioning regimens (RIC) and better supportive measures the elderly are able to receive Allo-SCT. A considerable number of patients are elderly, and often their HLA matched sibling donor is elderly, moreover. Here, we aim to explore the effect of donors' age on stem cell harvesting, engraftment duration after Allo-SCT, and product quality. METHOD: Sixty-one healthy allogeneic stem cell donors aged 50 years and older who underwent stem cell mobilization at our center between 2009-2019 were enrolled for the study. All donors received 4-5 days of G-CSF, mostly filgrastim or lenograstim and their biosimilar equivalents were given subcutaneously as a total dose of 10 mcg/kg/day. Groups were separated into three groups as aged 50-54 group A, 55-59 group B, aged 60 and older group C. RESULTS: Pre-apheresis peripheral blood CD34+ count was similar all groups (p = 0.2). One day apheresis was sufficient for 72.7 % of group A, 27.3 % for group B and 47.1 % for group C (p = 0.02). Total harvested CD34+ cells were comparable among groups (p = 0.5). CONCLUSION: Adequate stem cell harvest in older donors is feasible. Older donors may require more than one apheresis procedure and generally procedure was well tolerated. When assessing donors, age should represent less significance.

INTRODUCTION: Passive antibody therapy has been used to immunize vulnerable people against infectious agents. In this study, we aim to investigate the efficacy of convalescent plasma (CP) in the treatment of severe and critically ill patients diagnosed with COVID-19. METHOD: The data of severe or critically ill COVID-19 patients who received anti-SARS-CoV-2 antibody-containing CP along with the antiviral treatment (n = 888) and an age-gender, comorbidity, and other COVID-19 treatments matched severe or critically ill COVID-19 patients at 1:1 ratio (n = 888) were analyzed retrospectively. RESULTS: Duration in the intensive care unit (ICU), the rate of mechanical ventilation (MV) support and vasopressor support were lower in CP group compared with the control group (p = 0.001, p = 0.02, p = 0.001, respectively). The case fatality rate (CFR) was 24.7 % in the CP group, and it was 27.7 % in the control group. Administration of CP 20 days after the COVID-19 diagnosis or COVID-19 related symptoms were associated with a higher rate of MV support compared with the first 3 interval groups (≤5 days, 6-10 days, 11-15 days) (p=0.001). CONCLUSION: CP therapy seems to be effective for a better course of COVID-19 in severe and critically ill patients.

We report a 42-year-old patient who had Hodgkin lymphoma and developed bilateral symmetrical peripheral gangrene (SPG) in the feet and hands, which occurred during septic shock after autologous hematopoietic stem-cell transplantation. SPG is a rare but severe complication of disseminated intravascular coagulation (DIC) and is frequently associated with sepsis. The pathophysiology of SPG includes DIC-mediated intravascular thrombosis and thrombotic occlusion of microcirculation, resulting in low blood flow. Sepsis-induced hypotension has been suspected as one of the other causes of SPG, and it is thought to be aggravated by vasopressor treatments given for hypotension. Our patient first experienced coldness, paleness, and cyanosis in his body's acral parts, and then SPG later developed in both his feet and hands. Septic shock management was performed with cytokine hemoadsorption, broad-spectrum antibiotics, and massive fluid replacement rapidly. The patient fully recovered without the need for amputation. Hemoadsorption is an extracorporeal cytokine-adsorption method for removing excess cytokines. Prompt management of septic shock and early monitoring of peripheral ischemia are essential to avoid SPG.

Background/aim: SARS-CoV-2 enters the cell through the binding of the S glycoprotein on the surface of the virus to the angiotensin- converting enzyme 2 (ACE-2) in the host cells and also SARS-CoV S protein binding to ACE-2 was inhibited by anti-A antibodies. The aim of the study was to investigate the relationship between blood groups and the course of COVID-19 in Turkey. Materials and methods: Laboratory confirmed COVID-19 patients aged 18 and over (n = 39.850) were randomized in age and sex- matched groups according to blood groups. Results: Advanced age, male sex and blood group A were found to be related with increased rate of intensive care unit (ICU) admission (OR = 1.089, 95% CI: 1.0851.093 for age; OR = 1.963, 95% CI: 1.7372.218 for male sex; OR = 1.216, 95% CI: 1.0231.446 for blood group A). When blood group O individuals were compared to non-O individuals, no significant difference was observed regarding the rate of hospital and ICU admission, mechanical ventilation (MV) support, length of hospital and ICU stay, and case fatality rate (CFR). The CFR in patients with blood group A, B, O, and AB were 2.6%, 2.2%, 3.1%, and 2.3%, respectively. There were no significant differences between Rh-negative and positive patients regarding the rate of hospital and ICU admission (p = 0.280 and p = 0.741, respectively), also the rate of MV support and CFR was similar (p = 0.933 and p = 0.417). Conclusion: Our study revealed that ABO and Rh blood groups do not have any impact on the rate of hospital admission, hospital and ICU stay, MV support, and CFR.

Background/aim: Gemcitabine, dexamethasone and cisplatin (GDP) is a well-established salvage regimen for relapsed and refractory lymphomas. In this study, we aimed to share our experience with the patients who received GDP/R-GDP (rituximab-gemcitabine, dexamethasone and cisplatin) for stem cell mobilization. Materials and methods: Data of 69 relapsed and refractory Hodgkin lymphoma (HL) and Non-Hodgkin lymphoma (NHL) patients who received GDP/R-GDP as salvage chemotherapy in our center between July 2014 and January 2020 were retrospectively evaluated. After the evaluation of response, 52 patients had a chemosensitive disease and underwent mobilization with GDP/R-GDP plus GCSF (granulocyte colony-stimulating factor). Collected CD34+ stem cells and related parameters were compared in terms of diagnosis of HL and NHL, early and late stage, patients who did not receive RT and those who received RT, and patients aged under 60 and over 60. Results: On the 15th day on average (range 1120), a median number of 8.7 × 106 /kg (4.141.5) CD34+ stem cells were collected in 51 (98%) of our 52 chemosensitive patients and 1 (2%) patients failed to mobilize. We observed acceptable hematological and nonhematological toxicity. The targeted amount of 2 × 106 /kg CD34+ stem cells was attained by 98% (n: 51) patients, and all of them underwent autologous stem cell transplantation. Moreover, low toxicity profiles provide outpatient utilization option clinics with close follow-up and adequate supportive care. Conclusion: We suggest that GDP/R-GDP plus G-CSF can be used as an effective chemotherapy regimen for mobilizing CD34+ stem cells from peripheral blood in relapsed and refractory lymphoma patients due to low toxicity, effective tumor reduction, and successful stem cell mobilization. It can also be assumed that the GDP mobilization regimen may be more effective, especially in patients with early-stage disease and in HL patients.

The activation of the innate and adaptive immune systems by SARS-CoV-2 causes the release of several inflammatory cytokines, including IL-6. The inflammatory hypercytokinemia causes immunopathological changes in the lungs including vascular leakage, and alveolar edema. As a result of these changes in the lungs, hypoxia and acute respiratory distress syndrome occur in patients with COVID-19. Even though there are clinical trials on the development of therapeutics and vaccines, there are currently no licensed vaccines or therapeutics for COVID-19. Pharmacological approaches have shown poor results in sepsis-like syndromes caused by the hypercytokinemia. Suppressing the cytokine storm is an important way to prevent the organ damage in patients with COVID-19. Extracorporeal blood purification could be proposed as an adjunctive therapy for sepsis, aiming to control the associated dysregulation of the immune system, which is known to protect organ functions. Several extracorporeal blood purification therapies are now available, and most of them target endotoxins and/or the cytokines and aim improving the immune response. For this purpose, plasmapheresis and immunoadsorption may be an important adjunctive treatment option to manage the complications caused by cytokine storm in critically ill patients with COVID-19.

INTRODUCTION: Peripheric blood derived stem cells are used in 75 % of allogeneic stem cell transplantations. Iron, vitamin B12 and folate involve in hematopoiesis. Therefore serum levels of iron, vitamin B12 and folat may effect stem cell mobilization. We aimed to analyze the effects of iron status, vitamin B12 and folate levels on peripheric blood stem cell mobilization in healthy donors. METHOD: The mobilization results of 218 allogeneic donors were analyzed retrospectively. RESULTS: In 64 donors, serum ferritin level was <15 µg / L and transferrin saturation was <20 %. When we compared the donors with iron deficiency to the donors without iron deficiency, the number of collected CD34 + cell was significantly higher in donors without iron deficiency. We did not find any impact of serum vitamin B12 and folate level on CD34+ cells collected. CONCLUSION: Our study shows that serum ferritin and transferrin saturation have a greater effect on the amount of CD34+ cells collected from donors than serum vitamin B12 and folate levels. Consequently, when compliance tests of allogeneic donors are performed, the evaluation of vitamin B12 and folate levels is not necessary; whereas iron deficiency must be assessed and -if possible- corrected before apheresis is performed.

INTRODUCTION: Induction treatment followed by autologous stem cell transplantation (ASCT) has been accepted as the standard treatment for multiple myeloma (MM) patients. Granulocyte colony stimulating agent (G-CSF), chemotherapy or agents likes plerixafor are being used for the mobilization of stem cells from bone marrow. In this study, we evaluated the impact of the mobilization methods on the outcome of MM patients after ASCT. METHOD: The data of 205 MM patients who underwent ASCT at our center between December 2009 and January 2019 were retrospectively analyzed. Patients were divided into 2 groups as good mobilizers (patients who were mobilized with G-CSF alone) and poor mobilizers (patients who were failed to mobilize with G-CSF alone and mobilized with G-CSF + cylophosphomide or G-CSF + plerixafor). RESULTS: The median progression free survival (PFS) was 18.27 ± 3.22 months in good mobilizers and 14.22 ± 3.7 months in poor mobilizers. In G-CSF + cyclophosphamide method median PFS was 15.4 ± 4.9 months wheras it was only 4 months in G-CSF + plerixafor method. We did not find a statistically significant difference between good and poor mobilizers regarding median PFS (p: 0.342). The median overall survival (OS) was found 34.48 ± 4.2 months in good mobilizers and 15.13 ± 5.78 months in poor mobilizers. In G-CSF + cyclophosphamide method median OS was 17 ± 14.01 months wheras it was 10.66 ± 7.68 months in G-CSF + plerixafor method. We found a statistically significant difference between good and poor mobilizers regarding median OS (p: 0.007*). CONCLUSION: Our study shows that difficulty in stem cell mobilization is correlated with worse outcome.

There are currently no licensed vaccines or therapeutics for COVID-19. Anti-SARS CoV-2 antibody-containing plasmas, obtained from the recovered individuals who had confirmed COVID-19, have been started to be collected using apheresis devices and stored in blood banks in some countries in order to administer to the patients with COVID-19 for reducing the need of intensive care and the mortality rates. Therefore, in this review, we aim to point out some important issues related to convalescent plasma (CP) and its use in COVID-19. CP may be an adjunctive treatment option to the anti-viral therapy. The protective effect of CP may continue for weeks and months. After the assessment of the donor, 200-600 mL plasma can be collected with apheresis devices. The donation interval may vary between countries. Even though limited published studies are not prospective or randomized, until the development of vaccines or therapeutics, CP seems to be a safe and probably effective treatment for critically ill patients with COVID-19. It could also be used for prophylactic purposes but the safety and effectiveness of this approach should be tested in randomized prospective clinical trials.

INTRODUCTION: Multiple myeloma is a malignant neoplasm of plasma cells. Lenalidomide-dexamethasone treatment is a common treatment regimen used in refractory multiple myeloma. CASE REPORT: We describe the case of a 58-year-old male multiple myeloma patient with a history of relapse after six months of autologous stem cell transplantation. The patient had nausea and bloody diarrhea developed during lenalidomide treatment.Management and outcome: Computed tomography showed diffuse marked edematous thickness in the wall of colonic, hepatic and splenic flexure, transverse colon, descending colon and sigmoid colon. Colonoscopic observation revealed highly granular, hyperemic and fragile mucosa. Colon biopsy was consistent with ischemic colitis. Lenalidomide treatment was discontinued. One month later, colon findings were detected as normalized through a colonoscopy. DISCUSSION: Risk of developing ischemic colitis should be kept in mind in patients receiving lenalidomide which should be discontinued in cases with severe bloody diarrhea of unknown origin.

OBJECTIVE: To evaluate the possible neutropenia-related effects of administering adriamycin [doxorubicin], bleomycin, vinblastin, dacarbazine (ABVD) chemotherapy in Hodgkin's lymphoma patients with moderate or severe neutropenia without granulocyte-colony stimulating factor supplementation. METHODS: This study evaluated neutropenia-related outcomes and the need for granulocyte-colony stimulating factor use during the periods between chemotherapy rounds. Forty-three rounds of ABVD chemotherapy were evaluated in the study. The outcomes that could be related to neutropenia were analyzed. In addition, rounds of ABVD chemotherapy given in the presence of severe neutropenia were compared with ABVD chemotherapy rounds given in the presence of moderate neutropenia in terms of neutropenia-related outcomes and the need for granulocyte-colony stimulating factor use. The study only included patients with classical Hodgkin's disease (lymphoma). Patients with a final neutrophil count of <1 × 103 cells/µL (<1000 cells/µL) prior to chemotherapy round and those receiving ABVD chemotherapy for Hodgkin's lymphoma were included in the study. RESULTS: We observed that none of the patients with moderate neutropenia before the start of chemotherapy round needed granulocyte-colony stimulating factor, and four patients with severe neutropenia prior to the start of chemotherapy round required granulocyte-colony stimulating factor. However, there was no statistically significant relationship between the severity of neutropenia (in terms of moderate and severe) before chemotherapy and granulocyte-colony stimulating factor requirement after chemotherapy (p> 0.05). Furthermore, none of the patients included in the study had bleomycin-related lung toxicity during the treatment periods included in the study. CONCLUSION: Administering ABVD chemotherapy to patients with moderate neutropenia seems to be safe.

The optimal choice of salvage therapy for patients with relapsed/refractory non-Hodgkin lymphoma or Hodgkin lymphoma remains controversial. In this study, we aimed to share our experience in relapsed/refractory lymphoma patients who received GDP/R-GDP as salvage chemotherapy in our center. Data of 47 relapsed/refractory Hodgkin lymphoma and non-Hodgkin lymphoma patients who received GDP or R-GDP as salvage chemotherapy in our center between July 2014 and October 2017 were retrospectively evaluated. Non-Hodgkin lymphoma and Hodgkin lymphoma patients were divided into two groups as primary refractory and relapsed. The one-year overall survival was 100% (for relapsed) and 36.9% (for refractory) in the non-Hodgkin lymphoma groups, and 82.5% (for relapsed) and 80% (for refractory) in the Hodgkin lymphoma group. The one-year progression-free survival (PFS) was 72.7% (for relapsed) and 38.5% (for refractory) in patients with NHL, and 41% (for relapsed) and 18.2% (for refractory) in patients with HL. GDP/R-GDP seems to be a well-tolerated out-patient salvage regimen for relapsed/refractory non-Hodgkin lymphoma and Hodgkin lymphoma. Although proven efficacy, negative toxicity profile, and ease of administration, the application of gemcitabine-based therapy for patients with primary refractory non-Hodgkin lymphoma and Hodgkin lymphoma provided limited success.
