Only Foell et al. in a randomized clinical trial proved the safety of withdrawing MTX therapy after 6 months of stable remission versus 12 months. The results of this study that included 364 patients showed that a 12-month versus 6-month withdrawal of MTX did not reduce the re lapserate[51]. MTX withdrawal may result in disease flare in more than 50% of patients, and even more in younger children. A longer period on MTX treatment after remission may not prolong the duration of i...
