We recently started India's first proton beam therapy facility. Proton beam 
therapy because of its unique physical characteristics of minimal exit dose has 
an unequivocal dosimetric superiority over high-end photon/standard X-ray beam 
therapy and is particularly advantageous in growing children with curable 
cancers in view of their very high probability of long-term cures. We hereby 
report a case of a 7-year-old boy with a craniopharyngioma which had been 
subtotally resected and was subsequently treated with modern pencil beam proton 
therapy under high-precision image guidance. This is the first ever child ever 
to be treated with proton therapy in India.
