Standard treatment options in North America for childhood ALL that has recurred in the testes include the following: Standard approaches for treating isolated testicular relapse in North America include local radiation therapy along with intensive chemotherapy. persistent circulating leukemia cells at 7 to 10 days after the initiation of RAS pathway mutations (KRAS, NRAS, FLT3, and PTPN11) are common at relapse in B-ALL patients, and they were found in approximately 40% of patients at first relapse in one study of 206 children.

For a cohort of patients with PAX5 amplification diagnosed between 1993 and 2015, the 5-year EFS rate was 49% (95% confidence interval [CI], 36%61%), and the OS rate was 67% (95% CI, 54%77%), suggesting a relatively poor prognosis for patients with this B-ALL subtype. A small number of cases of IG::MYC-translocated leukemias with precursor B-cell immunophenotype (e.g., absence of CD20 expression and surface Ig expression) have been reported. In subgroup analyses of high-risk subsets, only those with CNS3 status at diagnosis appeared to benefit from cranial radiation therapy, with a significantly lower rate of CNS relapses (isolated/any) in irradiated patients. : Chimeric antigen receptor T cells for sustained remissions in leukemia.

In general, there was no significant difference in rates of impairment between nonirradiated survivors and those who received 18 Gy of cranial radiation therapy. For intermediate-risk and high-risk patients, the difference in 5-year EFS between arms did not meet the protocol definition of noninferiority (the 95% upper confidence bound for the difference was 0.055, which exceeded the preset noninferiority margin of 0.05); therefore, it could not be concluded that vincristine/dexamethasone pulses could be omitted in these patients without resulting in an EFS decrement exceeding 5%.
