In Thailand, though, the survival rate for ALL is unimpressive. In 2006, standardnational protocols for childhood leukemia treatment were implemented. We herein report the outcome of theALL national protocols and explanations behind discrepancies in outcomes between institutions. Materials andMethods: Between March 2006 and February 2008, 486 children with ALL from 12 institutions were enrolled inthe Thai national protocols. There were 3 different protocols based on specific criteria: one each for standard risk,high risk and Burkitt’s ALL. We classified participating centers into 4 groups of institutions, namely: medicalschools in Bangkok, provincial medical schools, hospitals in Bangkok and provincial hospitals. We also evaluatedsupportive care, laboratory facilities in participating centers, socioeconomics, and patient compliance. Overalland event-free survival were determined for each group using the Kaplan Meier method. Statistical differenceswere determined using the log-rank test. Previous outcomes of Thai childhood ALL treatment between 2003 and2005 served as the historic control. Results: Five-year overall survival of ALL treated using the Thai nationalprotocol was 67.2%; an improvement from the 63.7% of the 12-institute historical control (p-value=0.06). Therewere discrepancies in event-free survival of ALL between centers in Bangkok and up-country provinces (69.9%vs 51.2%, p-value <0.01). Socioeconomics and patient compliance were key elements in determining the outcome(65.5% vs 47.5%, 59.4% vs 42.9%) (p-value < 0.02). Conclusions: Implementation of standard national protocolsfor childhood leukemia in Thailand did not significantly improve the outcome of ALL. Factors leading to betteroutcomes included (a) improvement of treatment compliance (b) prevention of treatment abandonment and (c)financial support to the family.}, keywords = {Acute leukemia,children,national protocols,Thailand}, url = {https://journal.waocp.org/article_31133.html}, eprint = {https://journal.waocp.org/article_31133_f4c2314cb9ec1f983b0fa6bf74c94d51.pdf} }
