I alle studierne kombineret var følgende kovarianter statistisk signifikant associeret med en øget risiko for udviklingen af hand - foot syndrom: stigende capecitabin- startdosis (gram), faldende kumulativ capecitabin- dosis (0, 1 * kg), stigende relativ dosisintensitet i de første seks uger, længere behandlingsvarighed (uger), stigende alder (ved 10- års forøgelse), kvindeligt køn og med en god ECOG performancestatus ved baseline (0 versus ≥1).
In all studies combined, the following covariates were statistically significantly associated with an increased risk of developing HFS: increasing capecitabine starting dose (gram), decreasing cumulative capecitabine dose (0.1*kg), increasing relative dose intensity in the first six weeks, increasing duration of study treatment (weeks), increasing age (by 10 year increments), female gender, and good ECOG performance status at baseline (0 versus ≥ 1).
