Résumé
OBJECTIVE@#To investigate the clinical importance of combined detection of urinary amino acid metabolite --urinary tyrosine (UT) and tumor specific growth factor (TSGF) in the disease observation and curative effect evaluation of acute leukemia（AL）.@*METHODS@#In 87 cases of AL, the UT and TSGF levels were detected by using chemical chromogenic method and continuous monitoring method respectively. The 2 indicators of each treatment group were statistically analyzed and compared with that of 50 healthy control group.@*RESULTS@#In 87 AL patients, the levels of UT and TSGF after treatment were significantly lower than those before treatment (P0.05).@*CONCLUSION@#UT and TSGF levels are related with the metabolism of tumor cells in AL patients. UT level can be used to predict the recurrence of patients with CR. The combined dynamical monitoring of these 2 indicators can be used as the indexes for observation of AL status, evaluation of therapeutic efficacy, prediction of prognosis and relapse of AL.
