OBJECTIVE
Allergic reactions to pegaspargase during ALL therapy are typically due to antibodies against polyethylene glycol (PEG), which is also used as a stabilizing agent in mRNA-based SARS-CoV-2 vaccines. To evaluate the safety of these vaccines in patients with anti-pegaspargase antibodies.
METHODS
We retrospectively reviewed the records of patients treated for ALL who had received SARS-CoV-2 vaccinations. All patients had antibodies against pegaspargase assayed during ALL therapy prospectively and in response to clinical allergies. Symptoms of intolerance to vaccination were gathered retrospectively from chart abstraction.
RESULTS
SARS-CoV-2 vaccination was well tolerated in all 78 patients with prior exposure to pegaspargase as part of their leukemia therapy. No reactions were observed in the 54 patients without a history of anti-pegaspargase antibodies or in 19 patients with antibodies who received mRNA vaccination. 1 patient who received the polysorbate containing Janssen vaccine experienced mild symptoms after vaccination not meeting the criteria of clinical allergy which spontaneously resolved within 25 minutes.
CONCLUSION
SARS-CoV-2 vaccination is safe in this population.

OBJECTIVES
The aim of this retrospective study was to determine the response to a single injection of pegylated asparaginase ('pegaspargase') and to assess the tolerability and outcome of prolonged incorporation of pegaspargase into a modified COP (cyclophosphamide, vincristine, prednisolone) regimen in pegaspargase sensitive cats.
METHODS
Fifty-six client-owned cats with confirmed macroscopic high-grade lymphoma at any anatomical site were included. Treatment was commenced with a single pegaspargase injection. Cats showing an objective response were eligible to continue therapy with pegaspargase incorporated into a modified COP protocol and had their survival analysed using the Kaplan-Meier method and log-rank test.
RESULTS
Objective response to pegaspargase was reported in 46 cats (82%), including 21 (38%) complete and 25 (44%) partial responses. Thirty-four responders continued therapy with pegaspargase-COP as the first-line treatment. Of these, 31 cats (92%) achieved complete remission with a median duration of the first remission (disease-free survival [DFS]) of 816 days. The median overall survival time (OST) for all 34 cats treated with pegaspargase-COP was 181 days. Response to the initial pegaspargase injection before COP initiation was significantly associated with DFS ( = 0.04) and OST ( = 0.001). Median DFS/OST for cats with complete response to initial pegaspargase injection was significantly longer compared with those with partial remission (>1273 days/>2066 days vs 77 days/108 days, respectively). Cats with gastric lymphoma showed a significantly longer survival (OST 854 days, 1- and 2-year survival rate 57.1%) compared with cats with intestinal lymphoma (OST 102 days, 1-year survival rate 0%). The pegaspargase-COP protocol was generally well tolerated, but two deaths were likely attributable to treatment-related toxicity during the maintenance phase. Importantly, none of the cats experienced hypersensitivity, despite multiple repeated treatments with pegaspargase.
CONCLUSION AND RELEVANCE
Pegaspargase is an effective agent for feline lymphoma. Its incorporation into a COP chemotherapy protocol may confer a survival benefit, especially in cats with complete response to pegaspargase. Treatment is generally well tolerated, but careful monitoring is recommended. Further studies are required to assess the benefits of pegaspargase as monotherapy or as part of different multi-agent chemotherapy regimens.

Randomized Controlled Trial
Efficacy and Safety of a Pegasparaginase-Based Chemotherapy Regimen vs an L-asparaginase-Based Chemotherapy Regimen for Newly Diagnosed Advanced Extranodal Natural Killer/T-Cell Lymphoma: A Randomized Clinical Trial.
IMPORTANCE
The L-asparaginase-based SMILE (dexamethasone, methotrexate, ifosfamide, L-asparaginase, and etoposide) chemotherapy regimen has shown higher response rates and survival benefit over an anthracycline-containing regimen. However, the safety profile was not satisfied. A well-tolerated regimen with promising efficacy is lacking.
OBJECTIVE
To compare the efficacy and safety of the DDGP (dexamethasone, cisplatin, gemcitabine, and pegaspargase) regimen with the SMILE regimen in newly diagnosed advanced-stage (III/IV) extranodal natural killer/T-cell lymphoma (ENKL).
DESIGN, SETTING, AND PARTICIPANTS
This was an open-label, multicenter, randomized clinical trial that took place across 12 participating hospitals in China from January 2011 to February 2019. Patients were eligible if they were 14 to 70 years old with newly diagnosed ENKL in stages III/IV and had an Eastern Cooperative Oncology Group performance status of 0 to 2. Eligible patients were evenly randomized to either the DDGP or SMILE group.
INTERVENTIONS
Patients in each group were treated with the assigned regimen every 21 days for 6 cycles.
MAIN OUTCOMES AND MEASURES
The primary end point was progression-free survival (PFS), and secondary end points included overall response rate and overall survival (OS). The adverse events between the DDGP and SMILE groups were compared.
RESULTS
Among the 87 randomized patients, 80 received treatment (40 in the DDGP group and 40 in the SMILE group); the median (IQR) age was 43 (12) years, and 51 (64%) were male. The baseline characteristics were similar between the groups. At a median follow-up of 41.5 months, the median PFS was not reached in the DDGP group vs 6.8 months in the SMILE group (HR, 0.42; 95% CI, 0.23-0.77; P = .004), and the median OS was not reached in the DDGP group vs 75.2 months in the SMILE group (HR, 0.41; 95% CI, 0.19-0.89, P = .02). The PFS rate at 3 years and OS rate at 5 years were higher in the DDGP group vs the SMILE group (3-year PFS, 56.6% vs 41.8%; 5-year OS, 74.3% vs 51.7%). The overall response rate was higher in the DDGP group than in the SMILE group (90.0% vs 60.0%; P = .002). Grade 3 and 4 hematologic toxic effects were more frequently reported in the SMILE group vs the DDGP group (leukopenia, 85.0% vs 62.5%; neutropenia, 85.0% vs 65.0%).
CONCLUSIONS AND RELEVANCE
In this randomized clinical trial, the DDGP regimen showed promising preliminary results for patients with newly diagnosed local advanced ENKL. A confirmation trial based on larger population is warranted.

PEG-asparaginase is a key component in treatment regimens for acute lymphoblastic leukemia (ALL). Major side effects include thrombosis and bleeding; however, there is currently no consensus on methods to prevent these complications. In this multi-center retrospective cohort study of 101 adults, we compared two prophylaxis strategies: cryoprecipitate and fresh frozen plasma (Cryo/FFP) versus cryoprecipitate and antithrombin (ATIII). The overall incidence of venous thromboembolism (VTE) was not significantly different between the two groups (19.7% for Cryo/FFP and 8.6% in Cryo/ATIII, = 0.17), and neither was grade ≥3 bleeding (3% for Cryo/FFP and 11.4% for Cryo/ATIII, = 0.18). Given the significant cost associated with ATIII without a clear benefit, a careful benefit and risk analysis should be considered before utilizing ATIII as a prophylaxis strategy to prevent thrombosis or bleeding following asparaginase administration.

PURPOSE
To explore the best treatment for early natural killer/T (NK/T)-cell lymphoma, we compared the efficacy and safety of DDGP (pegaspargase, gemcitabine, cisplatin and dexamethasone) followed by radiotherapy (RT) and VIPD (etoposide, ifosfamide, cisplatin, and dexamethasone) followed by radiotherapy for newly diagnosed patients.
MATERIALS AND METHODS
40 newly diagnosed patients with stage I-II from January 2011 to November 2016 were treated with DDGP followed by radiotherapy or VIPD followed by radiotherapy. They were assessed in this study.
RESULTS
The complete response rate (CRR) and overall response rate (ORR) of the DDGP followed by radiotherapy group were higher than those of the VIPD followed by radiotherapy group (CRR: 85 % vs 50 %, P = 0.018; ORR: 95 % vs 65 %, P = 0.048). The 5-year progression-free survival (PFS) rate was better in the DDGP followed by radiotherapy group (83.3 % vs 44.4 %, χ2 = 7.809, P = 0.005). There was no significant difference in the 5-year overall survival (OS) rate between the two groups (83.0 % vs 72.1 %, χ2 = 0.231, P = 0.631). Treatment method (P = 0.011) and IPI score (P = 0.027) were independent risk factors for PFS. The DDGP followed by radiotherapy group was more prone to grade I-II clotting dysfunction (P = 0.004).
CONCLUSIONS
In patients newly diagnosed with early NK/T-cell lymphoma, those treated with DDGP followed by radiotherapy had a higher CRR and ORR and longer PFS than those treated with VIPD followed by radiotherapy, and adverse reactions were tolerable.

Review
Acute lymphoblastic leukemia (ALL) is a rare hematologic malignancy resulting in the production of abnormal lymphoid precursor cells. Occurring in B-cell and T-cell subtypes, ALL is more common in children, comprising nearly 30% of pediatric malignancies, but also constitutes 1% of adult cancer diagnoses. Outcomes are age-dependent, with five-year overall survival of greater than 90% in children and less than 20% in older adults. L-asparaginase, an enzyme not found in humans, depletes serum levels of L-asparagine. As leukemic cells are unable to synthesize this amino acid, its deprivation results in cell death. The success of asparaginase-containing regimens in the treatment of pediatric ALL, and poor outcomes with conventional cytotoxic regimens in adults, have led to trials of pediatric or pediatric-inspired regimens incorporating asparaginase in the adolescent and young adult (AYA) and adult populations. Initially purified from , newer formulations of asparaginase have been developed to address short half-life, high immunogenic potential, and manufacturing difficulties. Unfamiliarity with asparaginase use and management of its unique toxicities may result in treatment-decisions that negatively impact outcomes. In this review, we address the current use of asparaginase in the treatment of ALL, with an emphasis on its role in the treatment of adults, key clinical trials, recognition and management of toxicities, and ongoing directions of study.

Optimal treatment strategies for natural killer/T-cell lymphoma (NKTCL) patients with stage IV disease have not been well defined. In this prospective phase 2 study, we evaluated the treatment using MEDA (methotrexate, etoposide, dexamethasone and pegaspargase) as induction chemotherapy and autologous hematopoietic stem cell transplantation (Auto-HSCT) for consolidation. Patients with stage IV disease without prior L-asparaginase-based chemotherapy were eligible. Four cycles of MEDA were administered as induction treatment. Patients with complete response (CR, necessary to have complete metabolic remission of PET/CT, negative plasma EBV-DNA and negative EBER staining of bone marrow biopsy tissue) were consolidated by Auto-HSCT. A total of 53 patients were enrolled. The overall response (OR) rate and CR rate after four cycles of MEDA chemotherapy were 75.5% and 56.6%, respectively. Among them, 25 patients underwent Auto-HSCT. The 4-year overall survival (OS) rate and progression-free survival (PFS) rate were 58.0% (95% CI, 43.4%-70.0%) and 43.4% (95% CI, 29.9%-56.1%), respectively. Patients who underwent Auto-HSCT had a 4-year OS rate of 92.0% (95% CI, 71.6%-97.9%) and a 4-year PFS rate of 80.0% (95% CI, 58.4%-91.1%). Grade 3/4 neutropenia and thrombocytopenia occurred in 28.3% and 17.0% of the patients, respectively. MEDA chemotherapy is an effective induction regimen with reduced grade 3/4 hematological toxicities for stage IV NKTCL. Consolidation with Auto-HSCT can be considered as a potential approach to improve the long-term survival of CR patients after induction treatment.

Journal of Healthcare Engineering 2022To explore the relationship between vitamins levels and disease-related indicators in children with acute leukemia (AL).
OBJECTIVE
To explore the relationship between vitamins levels and disease-related indicators in children with acute leukemia (AL).
METHODS
A total of 107 hospitalized children with AL were enrolled in this study and assigned to one group in each of the following categories: infected group ( = 52) and noninfected group ( = 55); treatment remission group ( = 56) and nonremission group ( = 51); high-risk (HR) group ( = 44), intermediate risk (IR) group ( = 53), and slight risk (SR) group ( = 8); cyclophosphamide + cytosine arabinoside+6-mercaptopurine + pegaspargase group (CAML, = 15); methotrexate group (MTX, = 9); and vindesine + daunomycin + L-asparaginasum + prednisone (VALP, = 38). Hematological and serological parameters, hepatic and renal function, and changes in vitamins A, B1, B2, B6, B9, B12, C, D, and E serum content in children with AL were analyzed to investigate their relationship with AL disease-related factors.
RESULTS
The vitamin D level was significantly higher in the noninfected group than in the infected group ( < 0.05). Compared with the nonremission group, the level of vitamin B1 in the treatment remission group was significantly higher, while the levels of vitamin B6 and B12 were notably lower ( < 0.05). The levels of vitamins B6 and B12 were notably different among the treatment groups. Multivariate analysis showed that hemoglobin (Hb) and C-reactive protein (CRP) were predisposing factors of AL in children. The disease type (acute lymphoblastic leukemia/acute myelogenous leukemia) was the factor affecting remission in AL children. Abnormal kidney function and the occurrence of icterus were the influencing factors for the risk degree in AL children. Platelet (PLT) count, activated partial thromboplastin time (APTT), neutrophils (N), and immunophenotype were shown to affect the choice of therapeutic regimens.
CONCLUSION
There are notable vitamins imbalances in children with AL. The imbalances influence disease-related factors and therefore provide some references for the prognosis and treatment of AL.
