Motivation of Chinese patients with chronic myelogenous leukemia who have stopped the tyrosine kinase inhibitor / 白血病·淋巴瘤

ABSTRACT

Objective To analyze the motivation of Chinese patients with chronic myelogenous leukemia (CML) who have stopped the tyrosine kinase inhibitor (TKI). Methods Forty-seven CML patients who have stopped TKI provided informed consent prior to their participation in the study. These patients were divided into relapse and non-relapse group at the endpoint of the observation. None of the patients received any CML-associated therapies after TKI cessation. The reasons of withdrawal were analyzed statistically. Results The reasons for cessation included patient's request due to cost(59.57 %, 28/47), patient's plan to getting pregnant(8.52 %,4/47),side-effect of TKI(23.40 %,11/47)and other reasons(8.52 %,4/47).At the endpoint of observation, 23 patients suffered molecular relapse. Among them, 15 cases (65.22 %) were due to cost; 1 case (4.35 %) was due to getting pregnant, 5 cases (21.74 %) were due to side-effect and 2 cases (8.69 %) were due to other reasons. There was more frequency relapse in the group of insufficient cost. Conclusion The motivation of Chinese CML patients who have stopped TKI might show impact on the outcome,and the motivation is mainly related with history of drug reduction and withdrawal.
