title: Superior vena cava syndrome in children with malignancy: analysis of seven cases.
abstract: Superior vena cava syndrome (SVCS) is rare in children. In Veterans General Hospital-Taipei, a total of 364 cases of SVC syndrome were diagnosed in the past 12 years. Of them only seven cases were younger than 18 years of age, ranging from 6 to 17 years, and they were all caused by mediastinal tumor. The underlying malignancy included malignant lymphoma in 4, teratocarcinoma in one and unknown in 2. The most common initial symptom was cough, followed in order of frequency by chest discomfort or neck mass. Dyspnea, orthopnea, swelling of head and neck, and venous engorgement might develop gradually within one to three weeks. Of the reported seven cases, two cases received immediate resuscitation upon arrival but expired in 1-2 hours. The other five cases received treatment with intravenous steroid as well as chemotherapy, and three cases also received committent emergent radiotherapy. Two of them expired 4 months and 2 years after treatment, respectively. Of the two surviving cases, one has received a complete course of chemotherapy and the other is still under regular chemotherapy in our hospital. Both of them are stable till now.
