超声和CT在儿童神经母细胞瘤诊断、临床分期和治疗方案制定中的价值分析

目的:对比分析超声和CT对儿童神经母细胞瘤的诊断价值以及二者在该病临床分期和治疗方案制定中的价值。方法:筛选经病理证实的儿童神经母细胞瘤34例（其中术后证实瘤内钙化者26例），分析其临床及影像资料。结果:本研究的34例患者中，有29例超声显示为大小不等、回声不均匀的实性肿块，其中20例肿块表现为跨中线生长，18例包绕腹部大血管，18例后腹膜淋巴结肿大，且有9例、8例和2例分别为肾脏、肝脏、脾脏受累患者。本研究中有28例患者在术前通过超声进行了确诊，其符合率高达82.4%，特征性瘤内钙化的检出率达88.5%（23/26）；CT示大小不等、密度不均匀的肿块34例，增强可见明显强化，包绕大血管者18例，跨中线生长者20例，侵犯椎管腔者8例，后腹膜淋巴结肿大者15例，肾脏、肝脏、脾脏受累者分别为9例、6例、1例，头颅转移者7例，30例术前做出正确诊断，术前CT诊断符合率为88.2%，瘤内钙化的检出率高达96.2%（25/26）。结论:儿童神经母细胞瘤有其典型的影像学表现，超声和CT对该病的诊断符合率都很高，且各具优势，二者联合应用对儿童神经母细胞瘤的诊断、临床分期和指导治疗有重要价值。     

范忠泽辨治小儿神经母细胞瘤经验

范忠泽教授认为小儿神经母细胞瘤的病因分为胎产因素及外感六淫、邪毒侵袭、饮食失节、情志所伤、接触有毒之品等导致气血运行不畅,痰凝气滞血瘀,聚而成瘤。临床难点是小儿五脏六腑形气皆不足,中医辨证为肺脾肾气虚,治则是调补肺脾肾,扶正为本不忘祛邪。临床谨守病机,辨证论治,颇有良效。     

Cabozantinib for relapsed neuroblastoma: Single institution case series

Relapsed high‐risk neuroblastoma has few effective therapies currently available or in development. Cabozantinib is an Food and Drug Administration approved multitargeted tyrosine kinase inhibitor for select adult malignancies with preclinical data suggesting efficacy against neuroblastoma. A safe and tolerable dose has been identified for children, but its efficacy remains unknown. We describe four children with relapsed metastatic neuroblastoma treated with cabozantinib. All four patients had extended disease control (two complete responsesfor >12 months, 2 stable disease >6 months) with manageable predictable toxicities requiring dose reduction in two patients. We discuss the potential for the use of cabozantinib in neuroblastoma.
