It has a low incidence with a high degree of malignancy and a poor prognosis. Five years ago, we successfully treated a child with AT/RT. Treatment comprised total tumor resection, 6 MV X 3D conformal radiotherapy (DT: 36Gy/18FX) and six courses of chemotherapy, including teniposide 25 mg (qd × 5d), ACNU 25 mg (qd × 1d), vincristine 1 mg (qd × 1d). There was no tumor recurrence after 5 years of follow-up. We adjusted the previous AT/RT regimen to make it more suitable for the individual treatment of this patient, and now the patient has achieved a cure. So we think this regimen is effective and it is worthy of recommendation.展开更多

Current treatments for AT/RTs include surgery, radiotherapy, and chemotherapy;these treatments have poor prognoses and challenging side effects. The pivotal genetic event in AT/RT pathogenesis comprises the inactivation ofSMARCB1 orSMARCA4. Recent epigenetic studies have demonstrated mutual and subtype-specific epigenetic derangements that drive tumorigenesis;the exploitation of these potential targets might improve the dismal treatment outcomes of AT/RTs. This review aims to summarize the literature concerning targeted molecular therapies for pediatric AT/RTs.展开更多
