WebNo deaths were due to toxicity. High-dose cyclophosphamide-based chemotherapy with stem cell support after risk-adapted CSI results in excellent EFS estimates for patients with newly diagnosed AR SPNET. Further, this chemotherapy allows for a reduction in the dose of CSI used to treat AR SPNET without compromising EFS. WebVMAT CSI, along with chemotherapy and anesthesia, is feasible with supportive care. Daily image-guided RT improves accuracy and reduces the risk of spinal cord overdose …

The purpose of this study is to review late toxicity following craniospinal radiation for early-stage medulloblastoma. Material and methods. Between 1963 and 2008, 53 children with stage M0 (n = 50) or M1 (n = 3) medulloblastoma were treated at our institution. The median age at diagnosis was 7.1 years (range 1.2–18.5). Webthe most toxic with the lowest LC 50 of 323.7 ppm at 120 h after treatment. The CSI toxicity ranked by LC 50 values in descending order is lufenuron > flufenoxuron > chlorflu-azuron > buprofezin > novaluron. The toxicity gradually in-creased with CSI concentration (Figure 1A) and significantly increased with exposure duration, particularly for ... hideaway screens
