About this Calculator

The Sokal score was derived from 813 European and American patients treated from the 1960s-1980s, prior to the era of tyrosine kinase inhibitor therapy. Most individuals in the cohort were treated with single-agent chemotherapeutics. The EUTOS scoring system may offer improved prognostication in the era of TKI therapy
