Abstract:
OBJECTIVE:To evaluate the efficacy of the second-line nilotinib and third-line dasatinib on chronic myelogenous leukemia (CML) with failed first- and second-line treatments, and analyze the influencing factors of the efficacy.
METHODS:Selected 83 patients in The Third People's Hospital of Kunshan City, Jiangsu Province with CML who were treated with nilotinib as the second-line treatment after the failure of the first-line treatment with imatinib as the second-line treatment group (referred to as the second-line group) from January 2014 to December 2018, and 61 CML patients who were treated by dasatinib as the third-line treatment group (referred to as the third-line group) after the failure of the second-line treatment with nilotinib; the first-line treatment with imatinib failed, but due to various reasons, the patients were fully after being informed of the possible serious consequences of not changing the drug treatment, 37 CML patients who were still required to continue imatinib treatment served as the control group. The hematological, genetic and molecular responses of each group were compared for 3, 6, and 24 months of treatment. LogistiC regression was used to analyze the factors affecting the second and third line curative effects.
RESULTS:The three groups had statistically significant differences in the rates of achieving CHR, MCyR, and MMR at 3, 6, and 12 months of treatment (P<0.05). Compared the two groups, the CHR rates of the second-line group at 3, 6, and 12 months of treatment were 100.00%, 97.59%, and 95.18%, respectively; higher than the third-line group's 90.16%, 86.89%, 83.61% and the control group's 83.78%, 75.68% and 72.97%; the CHR rate of the third-line group was higher than that of the control group at 6 and 12 months of treatment. The rates of reaching MCyR at 3, 6, and 12 months after treatment in the second-line group were 87.95%, 93.98% and 93.98%, respectively, while those in the third-line group were 80.33%, 88.52% and 86.89%, which were higher than those of the control group of 67.57%, 64.86% and 48.65%. The rates of achieving MMR at 3, 6, and 12 months of treatment in the second-line group were 19.28%, 33.72% and 60.24%, respectively, and those in the third-line group were 11.48%, 26.23% and 49.18%, which were higher than those of the control group of 0.00%, 2.70% and 0.00%; The rate of reaching MMR within 12 months of treatment in the second-line group was higher than that of the third-line group, and the differences was statistically significant (P<0.05). There was no significant difference in the rate of reaching MCyR between the second-line group and the third-line group at 3, 6, and 12 months, and the rate of reaching MMR at 3 and 6 months (P>0.05). The incidence of nausea and vomiting among the three main non-hematological adverse reactions, and the incidence of grade 1~2 anemia among the hematological adverse reactions were statistically significant (P<0.05). There was no significant difference in the incidence of rash, eyelid edema, diarrhea, thrombocytopenia, leukopenia and neutropenia in the three groups (P>0.05). The incidence of nausea and vomiting and grade 1~2 anemia in the second-line group and the third-line group were higher than that of the control group, and the difference was statistically significant (P<0.05). There were statistically significant differences in Sokal score, medication compliance, and hematological adverse reactions between the MMR group and the non-MMR group (P<0.05). Logistic regression analysis showed that dose reduction or withdrawal during the treatment period, and grade 3~4 hematological adverse reactions were the main factors affecting the second and third line curative effects (OR=22.160, 2.715, 95% CI=2.795-93.027, 1.882-48.834).
CONCLUSION:The second-line nilotinib and the third-line dasatinib have a better effect on CML patients who have failed the first and second-line treatments. Grade 3~4 hematological adverse reactions, dose reduction or withdrawal are risk factors that affect the efficacy of second and third-line treatments.
