A total of 6,345 patients have been entered in the RTOG particle registry since it was opened in 1980. Three hundred thirty of those patients were treated with neutrons alone for head and neck cancers, and 128 were treated with neutrons alone for pelvic cancers. The late normal Tissue Severe Toxicity (life-threatening and fatal) rates in the head and neck were 9% for high energy accelerators and 20% for low energy accelerators. The late normal Tissue Severe Toxicity rates in the pelvis were 4% for high energy accelerators and 39% with low energy accelerators.
自1980年开放以来，共有6345名患者被纳入RTOG粒子登记系统。其中330名患者仅接受中子治疗头颈部癌症，128名患者仅接受中子治疗盆腔癌症。头颈部高能加速器的晚期正常组织严重毒性（危及生命和致命）发生率为9%，低能加速器为20%。盆腔高能加速器的晚期正常组织严重毒性发生率为4%，低能加速器为39%。
