Executive summary

This study compared the neuroendocrine outcomes of 112 pediatric primary brain tumor patients treated with XRT(n = 80) or PRT (n = 32). With a median follow-up of 6.3 years for XRT and 4.4 years for PRT, the common endocrinopathies occurred were growth hormone deficiency (26% XRT, 38% PRT) and hypothyroidism (29% XRT, 19% PRT). In CSI cohort, PRT patients had less hypothyroidism (p = 0.045). Sex hormone deficiency developed in 17.1% of the XRT CSI group but did not occur in the PRT CSI group.
