Comparison of the Effects of L-asparaginase and Pegaspargase in the Treatment of Adult Acute Lymphoblastic Leukemia

Objective:To compare the effect of L-asparaginase and pegaspargase in the treatment of adult acute lymphoblastic leukemia.Methods:In this study,96 patients who received treatment at the Shaanxi Provincial People’s Hospital from April 2019 to April 2021 were selected.The control group received L-asparaginase treatment,and the observation group received pegaspargase treatment.The curative effect and adverse reaction rate were compared between the two groups.Results:Comparing the experimental statistical results of the observation and the control groups,it can be concluded that the effect of the former group is better than that of the latter group in terms of clinical curative effect and statistics of adverse reactions.Conclusion:In the treatment of adult acute lymphoblastic leukemia,the application of pegaspargase therapy has a significantly better clinical effect and is worthy of further promotion.

Using Pegaspargase in Combination with Chemotherapy in the Treatment of Lymphoma

Objective:To analyze the clinical effect of pegaspargase combined with chemotherapy on patients with lymphoma.Methods:Seventy patients with lymphoma admitted to Shaanxi Provincial People’s Hospital between December 2020 and June 2021 were selected as study subjects and were equally divided into the control group and the intervention group using the lottery method,with 35 cases in each group;the control group received conventional treatment,while the intervention group received pegaspargase combined with chemotherapy.The treatment satisfaction,quality of life,psychological status,and incidence of adverse reactions of the patients in the two groups were compared.Results:The differences in the indicators between the two groups were statistically significant(p<0.05).Conclusion:Pegaspargase combined with chemotherapy can effectively improve the treatment effect and satisfaction of lymphoma patients;hence,it is worthy of promotion in clinical treatment.

Analysis of clinical efficacy of P-Gemox regimen sandwich radiotherapy,P-Gemox regimen sequential radiotherapy,and radiotherapy alone treatment for extranodal natural killer/T-cell lymphoma

Objective The study aimed to explore the clinical efficacy of P-Gemox regimen sandwich radiotherapy, P-Gemox regimen sequential radiotherapy, and radiotherapy alone in early-stage extranodal natural killer/T-cell lymphoma(ENKTL).Methods In total, 124 patients with early-stage ENKTL, from June 2009 to January 2016, were retrospectively analyzed to compare the clinical efficacy of the three regimens. Results A total of 46 patients were treated with P-Gemox regimen sandwich radiotherapy, with complete remission(CR) of 91.3%, objective response rate(ORR) of 97.8%, 2-year progression-free survival(PFS) of 76.1%, and 2-year overall survival(OS) of 80.4%. Then, 37 patients received P-Gemox regimen sequential radiotherapy, with CR of 86.5%, ORR of 94.6%, 2-year PFS of 75.7%, and 2-year OS of 81.1%. Finally, 41 patients received radiotherapy alone, with CR of 61.0%, ORR of 80.5%, 2-year PFS of 51.2%, and 2-year OS of 65.9%. When the two groups were compared, significant differences in CR, PFS, and OS were observed among the sandwich radiotherapy, sequential radiotherapy, and radiotherapy alone groups(P < 0.05), respectively. However, no significant difference in CR, ORR, PFS, and OS was observed between the sandwich radiotherapy and sequential radiotherapy groups(P > 0.05). Multivariate analysis revealed that Eastern Cooperative Oncology Group(ECOG), serum lactate dehydrogenase(LDH), plateletto-lymphocyte ratio(PLR), local tumor invasion, and treatment modalities were independent prognostic factors for PFS(P < 0.05). ECOG, LDH, PLR, local tumor invasion, underlying disease, and treatment modalities were independent prognostic factors for OS(P < 0.05).Conclusion P-Gemox regimen combination radiotherapy for patients with early-stage ENKTL was better than the radiotherapy alone.
