One in four children with ALL misses maintenance doses

In African American households, those with low maternal education had significantly lower adherence rates, 74.6%, than in those households in which mothers held a college degree, 94.6%. And adherence rates were higher in households with single parents and a single child (94.2%) compared with those households with a single parent and multiple children (80.5%) or even from nuclear families (85.5%).

In non-Hispanic white households, paternal education higher than a postgraduate degree resulted in adherence of 97.2%, compared with households in which the father did not have a postgraduate degree, (95.3%). Again, adherence rates were higher in households with single parents and a single child (97.8%) compared with those from single parents with multiple children (94.0%) or from nuclear families (95.6%).

For all racial groups, forgetfulness was the most common reason for missing doses—non-Hispanic whites, 79%; Asians, 90%; and African Americans, 75%.

“Our data demonstrate that one in four children in remission from ALL does not take the medicine needed to remain cancer free,” said Dr Bhatia, “and in an overwhelming majority, the primary reason why is that they forget to take their pills each day,” said Dr. Bhatia.

“These results are the basis for further studies that will examine how physicians can successfully intervene, using technology, for example, to ensure that children do not experience an increased risk of relapse because they did not take their oral chemotherapy.”
