Applicability of ESMO-MCBS and ESCAT for molecular tumor boards

Scoring systems for classifying genomic alterations (GAs) with respect to their potential targeted anticancer therapies (TTs) may be useful for rational and evidence-based decision-making, for example in molecular tumor boards. Therefore, a working group of the European Society for Medical Oncology (ESMO) has developed a comprehensive and reproducible classification score that allows the ranking of GAs and TTs according to their level of evidence and clinical relevance. This score is called the ESMO Scale for Clinical Actionability of Molecular Targets (ESCAT). Another score not explicitly developed for TTs but helpful in grading novel TTs is the ESMO-Magnitude of Clinical Benefit Scale (ESMO-MCBS). This tool was designed to objectively quantify the clinical benefit of novel approved therapies. The current review summarizes the status quo of these scores and their applicability for molecular tumor boards.
