Evaluate the Response Rate of Acute Lymphocytic Leukemia Patients to Hyper Cyclophosphamide, Vincristine, Adriamycin, and Dexamethasone Regimen and Remission Rate to Stay Until the End of the Arbitrary Treatment

Background: This study aimed to determine the effect of Hyper-Cyclophosphamide, Vincristine, Adriamycin, and Dexamethasone (CVAD) in the treatment of acute lymphoblastic leukemia (ALL) patients and remission duration. Materials and Methods: During a cross-sectional study in the Seyed Al-Shohada Hospital in Isfahan, patients with ALL who were admitted and treated from 2011 to 2015 because of the risk of ALL were selected and through the records investigation, demographic information, disease information, treatment, remission duration, current status, and duration of survival were collected in the form of data and are sick after going into remission, including the duration and recurrence remission survival time in treatment were analyzed and consequence, whether the patient is going into remission, remission and relapse and survival time based on the duration of treatment were analyzed. Results: Of the 62 patients, 13 patients after starting of treatment did not go to remission and died, but 49 patients (79%) went into complete remission. 21 of them of Hyper-CVAD group and 28 patients of classical treatment group (75/7% vs. 84%), but the difference was not significant (P = 0.43). Of the 48 patients who had a complete remission with the treatment regimen, ten patients relapsed after treatment with two of them of Hyper-CVAD group and eight patients were in the classical treatment group (9/5% vs. 29/6%), and the difference between the two groups was significant (P = 0.015). Conclusion: Hyper-CVAD regimen resulted in increased survival time of patients with ALL and less disease recurrence and therefore contraindications for use if the existing rules, and under the supervision of treatment, can be used.
