Adv Hematol 2023; 2023:5593635. [PMID: 38029004 PMCID: PMC10653974 DOI: 10.1155/2023/5593635] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2023] [Revised: 07/08/2023] [Accepted: 10/21/2023] [Indexed: 12/01/2023] Open
Abstract
Aim The Hyper-CVAD regimen has shown promising results for adult patients with acute lymphoblastic leukemia (ALL), as designed by the MD Anderson Cancer Center (MDACC). This treatment has resulted in a complete remission rate of 92% and a 5-year overall survival of 38%. However, given the diversity of patient demographics and institutional methods, outcomes may differ between various institutions. This study will compare the outcome of adult ALL patients treated with the Hyper-CVAD regimen in Iran with those obtained in the original series presented at the MDACC. Patients and Method. In this retrospective study, we evaluated the 2-year leukemia-free survival (LFS) and the 2-year overall survival (OS) of 70 ALL patients treated between 2014 and 2019 in the Seyed Al-Shohada Hospital in Isfahan, Iran. Results In total, 59 ALL patients (84.28%) achieved complete remission (CR). The CR rate had statistical differences by bone marrow transplantation (BMT) and WBC count. The 2-year LFS and OS were 40% and 42%, respectively. There were significant differences in LFS and OS by BMT, myeloid marker, and WBC count. Conclusion The outcome of the traditional Hyper-CVAD regimen in treating adult ALL was not satisfying. More efficient therapies should be applied for the treatment of adult ALL.

Abstract
OBJECTIVE to discuss the status and challenges associated with the management of acute lymphoblastic leukemia (ALL) in Latin America. METHODS This review summarizes various insights gained from information regarding diagnostic approaches and treatment strategies in adult patients with ALL in Latin American Countries. RESULTS Information regarding ALL in Latin America is scarce; however, many efforts have been made to overcomes these barriers. Nevertheless, major obstacles to successful treatment in Latin America and LMIC remain poor adherence, abandonment of treatment, and lack of supportive therapy and new therapeutic agents. CONCLUSION Further improvements in survival should be pursued by developing more Latin American registries, forming cooperative groups, developing educational models to facilitate earlier diagnosis and prevention of complications, better support therapy and management of infections, and adapting treatment strategies.

Leuk Res 2022; 119:106885.

Abstract
BACKGROUND Hyper-CVAD is an established regimen for adult ALL that was developed at the MD Anderson Cancer Center (MDACC). However, results can vary across different institutions given the heterogeneity of patient populations and institutional practices. Moreover, while a MDACC study demonstrated that the combination of ponatinib plus hyper-CVAD produced remarkable activity in untreated Ph+ ALL, it remains to be externally validated. We sought to validate those findings in previously untreated adult patients with Ph+ ALL. METHODS This was a retrospective study analyzing the outcomes of previously untreated adult ALL patients treated with hyper-CVAD, with a focus on Ph+ ALL patients treated with ponatinib plus hyper-CVAD. RESULTS 82 patients were included. The median age was 51 years. The median follow-up was 2.62 years. The 5-year overall survival (OS) and event-free survival (EFS) were 39.5 % and 28.2 %, respectively. For Ph+ ALL patients (n = 13) receiving ponatinib plus hyper-CVAD, 3-year OS and EFS were both 92.3 %. Univariate analysis showed a high WBC and poor-risk cytogenetics to be associated with inferior outcomes, while CD20 + predicted favorable outcomes in B-ALL patients. On multivariate analysis, CD20 + retained significance for Philadelphia-negative (Ph-) ALL. For Ph+ ALL, ponatinib was associated with better OS and EFS on univariate and multivariate analysis. CONCLUSION Our data supports the use of ponatinib plus hyper-CVAD as a standard of care regimen for Ph+ ALL. Our outcomes for Ph-ALL and T-cell ALL (T-ALL) show that advances are still needed in the frontline setting, and clinical trial enrollment is recommended.

Abstract
Outside of clinical trials, few studies have addressed the outcomes of Ph+ acute lymphoblastic leukemia (ALL) in adults, especially from developing world. In this study, we conducted a multicenter analysis on the outcomes of patients aged > 15 years with Ph+ ALL, aiming to get to know an overview of the Brazilian experience as well as to explore baseline factors associated with relapse and mortality in our setting. Over these 10 years, patients were treated with diverse protocols, all of them always combined with a frontline tyrosine-kinase inhibitor. A total of 123 Ph+ ALL patients was included. Imatinib was the first line TKI in 97 %. The complete response rate was 79 %. The early death rate was 15 %, being associated with increasing age at diagnosis (p = 0.06). The use of intensive versus attenuated induction regimen was not associated with higher induction mortality (p = 0.99). Overall, 29 % of patients aged ≤ 60 years underwent allogeneic transplantation, 87 % in first CR. 4-year overall survival (OS) and relapse-free survival were 25 % and 24 %, respectively. The incidence of relapse (death as a competitor) was 29 %, while the non-relapse mortality was 42 %. Only age was independently associated with OS, and lactate dehydrogenase level and central nervous disease at diagnosis were related to relapse in our cohort. This is the first historical cohort multicenter study on Ph+ ALL from Brazil. Reporting these outcomes is essential to encourage public policies to expand access to new drugs and transplantation in middle-income countries.

Abstract
Hyperfractionated cyclophosphamide, vincristine, adriamycin, and dexamethasone (Hyper-CVAD) is an important chemotherapeutic regimen for acute lymphoblastic leukemia (ALL) and non-Hodgkin's lymphoma. We present a case of a 23-year-old male with T-cell ALL and visual acuity of 20/20 in the right eye and 20/25 in the left eye who developed significant changes in his vision after starting Hyper-CVAD therapy. The patient initially presented with cotton wool spots in the fundus shortly after starting the regimen. After going through the induction phase of chemotherapy, he had a sudden decline in his vision to light perception in the left eye. Posterior segment exam revealed retinal ischemia and multilayered hemorrhages in both eyes as well as a large preretinal hemorrhage obscuring the fovea in the left eye. Labs associated the appearance of these hemorrhages with a significant decrease in hemoglobin and a platelet count of 5 K/μL. A Nd:YAG laser applied in the left eye at the posterior hyaloid face allowed blood to drain into the vitreous cavity and brought the patient's visual acuity back to baseline. Hyper-CVAD is an aggressive chemotherapy regimen that can cause severe thrombocytopenia secondary to myelosuppression. Frequent retinal evaluations and timely intervention is advisable in these cases as extensive intraretinal hemorrhages may cause irreversible damage.

Abstract
BACKGROUND Although cure rates in pediatric acute lymphoblastic leukemia (ALL) are quite high with combined chemotherapy regimens, complete response (CR) and long-term survival rates in adults are 80-90 and 30-40%, respectively. Currently, combined chemotherapy regimens, such as Hyper-CVAD and PETHEMA, are used in patients with adult ALL. However, there has been no study comparing the results of Hyper-CVAD and PETHEMA ALL-93. METHODS In this retrospective single-center study, we evaluated the results of Hyper-CVAD and PETHEMA ALL-93 in 51 ALL patients treated between September 2008 and March 2017 at the Department of Hematology, Faculty of Medicine, Karadeniz Technical University. RESULTS Thirty-eight patients were treated with Hyper-CVAD and 13 with PETHEMA ALL-93. CR was obtained in 90 and 100% of patients, respectively. Survival estimates were comparable between Hyper-CVAD and PE-THEMA ALL-93, with a median overall survival (OS) and a median disease-free survival (DFS) of 17.5 and 12.1 months, respectively, for Hyper-CVAD and of 18.6 and 12.9 months, respectively, for PETHEMA ALL-93. The 2-year OS rates for Hyper-CVAD and PETHEMA ALL-93 were 30 and 40%, respectively, and the 2-year DFS rates were 28 and 44%, respectively. PETHEMA ALL-93 resulted in more hepatotoxicity, hypofibrinogenemia, aspergillus infection, and skin rash than Hyper-CVAD. CONCLUSIONS Although Hyper-CVAD and PE-THEMA ALL-93 showed similar effects, Hyper-CVAD was tolerated better. Age and comorbidities should be taken into account before a chemotherapy regimen is determined for patients with ALL.

Abstract
Acute lymphoblastic leukemia (ALL) is a hematologic malignancy characterized by the clonal expansion of hematopoietic lymphoid progenitors. With new target therapies, the survival of adults with ALL has improved in the past few decades. Unfortunately, there are no large ALL patient series in many Latin American countries. Data from the Acute Leukemia Workgroup that includes five Mexico City referral centers were used. Survival was estimated for adult patients with ALL during 2009-2015. In total, 559 adults with ALL were included. The median age was 28 years; 67% were classified into the adolescent and young adult group. Cytogenetic information was available in 54.5% of cases. Of the 305 analyzed cases, most had a normal caryotype (70.5%) and Philadelphia-positive was present in 16.7%. The most commonly used treatment regimen was hyper-CVAD. In approximately 20% of cases, there was considerable delay in the administration of chemotherapy. Primarily refractory cases accounted for 13.1% of patients. At the time of analysis, 26.7% of cases had survived. The 3-year overall survival was 22.1%. The main cause of death was disease progression in 228 (55.6%). Clinical and public health strategies are needed to improve diagnosis, treatment and survivorship care for adult with ALL. This multicentric report represents the largest series in Mexico of adult ALL patients in which a survival analysis and risk identification were obtained.

Abstract
Several chemotherapy regimens have been developed for the treatment of acute lymphoblastic leukemia (ALL), but relapse still presents the most common obstacles to attaining long‐term survival. The hyper‐CVAD (hyperfractionated cyclophosphamide, vincristine, doxorubicin, and prednisolone)/HD MTX and Ara‐C (high‐dose methotrexate and cytarabine) chemotherapy regimen was first started in the MD Anderson Cancer Center as an intensive regimen for adult patients with ALL. The purpose of this study was to evaluate the effectiveness of a modified hyper‐CVAD protocol. We used hyper‐CVAD as consolidation/maintenance after remission induction with daunorubicin, vincristine, and prednisolone (and cyclophosphamide for T‐cell ALL only) rather than standard hyper‐CVAD in order to reduce treatment complications. This study was conducted as a retrospective review of medical records of ALL patients at 501 army hospital, Tehran, Iran, from 2005 to 2015. Three hundred and one patients underwent modified hyper‐CVAD chemotherapy regimen. Complete remission and overall survival (OS) rates were measured as primary endpoints. Two hundred and forty‐six (81.7%) reached complete remission (CR) during the first 6 months of treatment, and 55 patients (18.3%) did not reach CR. The 5‐year OS rate was 51.8% (95% CI (confidence interval): 45.1–57.8%). Modified hyper‐CVAD regimen is an efficient intensive chemotherapy regimen for consolidation/maintenance of adults with newly diagnosed ALL and has an acceptable 5‐year overall that is comparable to standard hyper‐CVAD regimen.

Abstract
BACKGROUND The use of intensive pediatric protocols for the treatment of ALL is being extended to older adults. AIM OF THE STUDY Analysis of the efficacy and toxicity results of pediatric DFCP vs. classic Hyper-CVAD protocol for the treatment of patients with ALL < 50 Y. PATIENTS AND METHODS A retrospective single center comparative analysis of DFCP & classic Hyper-CVAD for first line treatment of patients with ALL < 50 Y. RESULTS 73 patients were included, 43 received DFCP and 30 received Hyper-CVAD protocol. CR rate was 90.7% for DFCP vs. 83.7 for Hyper-CVAD (p 0.7). 3 Y Leukemia free survival was 57.4% (70.9% for DFCP vs. 41.6% Hyper-CVAD P 0.1) while 3Y OS was 62.6%% for the whole group, 72.6% DFCP vs. 48.5% Hyper-CVAD, P 0.04. Those with age <21 Y, had significantly longer 3 Y LFS and OS (P 0.04, 0.02, respectively). TOXICITY pancreatitis occurred in 5 patients with DFCP and it was related to Asparginase and in 1 patient on Hyper-CVAD related to gall stones. Osteonecrosis affected 5 patients on DFCP. IN CONCLUSION pediatric protocols are feasible in patients younger than 50 Y and they are more active than classic adult protocols. Although modifications of adult protocols may improve their results, this had to be investigated in randomized controlled trials.
