The purpose of this page is to provide references to regimens that are obsolete, outdated, or of historical interest only. As a general rule, this includes the inferior arm(s) of a randomized study, unless said regimens continue to be recommended by trustworthy sources such as the NCCN Guidelines. Is there a regimen missing from this list? See the main pediatric B-ALL page for current regimens.

Upfront induction therapy

Aminopterin monotherapy

Regimen

Study Dates of enrollment Evidence
Farber et al. 1948 1947-1948 Non-randomized pilot

Note: This regimen is of major historical interest, being one of the first published cancer chemotherapy experiments in man that led to an active non-clinical-trial intervention (to be distinguished from the trial of diopterin and teropterin published in Science in 1947). This agent is no longer available but was used clinically for several decades.
