ABSTRACT
Objective:To analyze the efficacy and safety of CLAG regimen (cladribine, cytarabine, granulocyte colony-stimulating factor) in treatment of relapsed/refractory acute myeloid leukemia (AML).Methods:The clinical data of 30 patients with relapsed/refractory AML who were admitted to Suzhou Hongci Blood Disease Hospital from January 2018 to February 2021 were retrospectively analyzed, and the efficacy and adverse reactions were observed.Results:Among 30 patients, 1 patient was not evaluated for efficacy due to treatment-related death. Among the 29 evaluable patients, 17 patients (58.6%) achieved complete remission (CR), 5 patients (17.3%) achieved partial remission (PR) and 7 patients (24.1%) had no remission (NR). One patient in low-medium-risk group achieved CR; the CR rate in medium-risk group was higher than that in high-risk group [68.8% (11/16) vs. 41.7% (5/12)], but the difference was not statistically significant ( P = 0.250). Seven patients with M 5 achieved CR. Five patients with positive MLL gene rearrangement achieved CR. Among 6 patients with extramedullary invasion of leukemia cells, 4 patients achieved CR, and among them 3 patients with central nervous system invasion achieved CR. Among 6 patients with cladribine 3.5 mg·m -2·d -1×5 d, 1 patient died of infection after chemotherapy, 1 patient had NR, and the rest achieved CR. Among 24 patients with cladribine 5 mg·m -2·d -1×5 d, the CR rate in patients with cytarabine 2 g·m -2·d -1×5 d was higher than that in patients with cytarabine 1 g·m -2·d -1×5 d [70.0% (7/10) vs. 42.9% (6/14)], but the difference was not statistically significant ( P = 0.240). All patients developed grade Ⅳ myelosuppression after chemotherapy. 12 patients underwent allogeneic hematopoietic stem cell transplantation (allo-HSCT) after CR, and 9 patients were still alive. Conclusions:CLAG regimen is effective and well tolerated in the treatment of relapsed/refractory AML. In order to improve the prognosis, allo-HSCT should be performed as soon as possible after CR.
ABSTRACT
Objective To evaluate the remission situation of early re-induction with priming low dose regimen containing G-CSF in treating acute myeloid leukemia (AML).Methods Ninety-seven AML patients in our hospital from March 2015 to January 2017 were retrospectively analyzed.All cases adopted the standard DA regimen for conducting the induction chemotherapy,among them,38 cases had significant residual disease on 14 d of induction chemotherapy,21 cases adopted the low dose priming regimen for conducting the early re-induction chemotherapy,17 cases adopted the tandard DA gregimen for conducting the re-induction chemotherapy.The complete remission(CR) rate and and adverse reactions were compared between two groups.Results The total CR rate in all 97 cases was 60.8％;among 38 cases needing re-induction chemotherapy,the CR rate in the priming regimen re-induction group was 76.2 ％,which was significantly higher than 41.2 ％ in the DA regimen re-induction group,the difference was statistically significant (P=0.028);the occurrence rates of side effects such as infection and cytopenia during re-induction chemotherapy process had no difference between two groups(P＞0.05).Conclusion For AML patients with obvious residual disease on 14 d of induction chemotherapy,adopting low dose priming regimen in re-duction chemotherapy has higher CR,which is superior to the standard DA regimen.
ABSTRACT
Introdução: o Adalimumabe (ADA) é um anticorpo monoclonal totalmente humano, utilizado no tratamento da doença de Crohn (DC). Nos casos com necessidade de interrupção desta terapia, o resgate da resposta é controverso, e o papel da reindução da remissão com dose total de ataque pode ser uma alternativa nos casos graves da DC. Não há relatos desta forma de tratamento na literatura. O objetivo deste estudo foi relatar a experiência de dois pacientes tratados com reindução da remissão com ADA, após sua interrupção. Método: análise retrospectiva de dois casos submetidos a reindução em meio a uma coorte de 24 pacientes em uso de ADA para DC. Resultados: são descritos dois casos de pacientes jovens, em tratamento com ADA subcutâneo, que tiveram necessidade de interrupção da terapia (um por abscesso perineal extenso e outro por dificuldade de acesso ao fornecimento da medicação). Ambos foram tratados pela reindução com dose total de ataque do ADA, com bons resultados, sem efeitos adversos. Conclusão: não há na literatura estudos controlados que comparem a reindução com outras formas de resgate da terapia após a parada de qualquer agente anti-TNF. Experiências isoladas mostram bons resultados com esta alternativa terapêutica em casos graves e selecionados.
Introduction: Adalimumab (ADA) is a fully-human anti-TNF-alpha antibody approved for the management of Crohnïs disease (CD). In situations in which interruption of the treatment is mandatory, rescue therapy is controversial. Reinduction of remission with full dose may be an alternative in severe CD cases. There are no descriptions of this alternative in the literature. The aim of this study was to describe the experience with two patients treated with reinduction of remission with ADA, after interruption of treatment. Method: retrospective analysis of two patients in a cohort of 24 CD patients treated with ADA, with case reports. Results: description of two young patients with fistulizing CD, with the need of interruption of ADA therapy due to different reasons (perianal abscess and difficulties in receiving the medication). Both were treated with reinduction of remission with full dose ADA regimen (160/80 mg), with good results and no adverse events. Conclusions: there are no studies in the literature comparing reinduction of remission with other possibilities of rescue therapy after interruption of treatment with any anti-TNF agent. Small case series like this, show good results with this alternative in selected and severe cases of CD.
