The mortality rate of patients with retinoblastoma still varies in developing countries, and data for Asia and Taiwan are relatively scarce. In this retrospective study, we aimed to describe the survival characteristics and prognostic factors of 54 retinoblastoma cases diagnosed at the Taipei Veterans General Hospital between 1982 and 2004. From medical(More)
BACKGROUND AND PURPOSE Taiwan Pediatric Oncology Group (TPOG)-W-91 is the first multi-institutional Wilms' tumor study for children in Taiwan. This clinical trial used a multidisciplinary approach, based on and similar to the National Wilms' Tumor Study 4. The study was conducted to evaluate the epidemiological characteristics and analyze the outcome of(More)
A 4 1/2-year-old girl presented with an incompletely resected, huge, immature abdominal teratoma, elevated serum alpha-fetoprotein (AFP), and numerous miuiary gliomatosis peritonei (GP). Two courses of chemotherapy resulted in normalization of her AFP level and marked tumor shrinkage. Further chemotherapy was interrupted by complications. During treatment(More)
BACKGROUND Reinduction therapy has improved the outcomes in children with acute lymphoblastic leukemia (ALL). We sought to determine the optimal course(s) of reinduction therapy for standard-risk (SR, or "low-risk" in other groups) patients. Also, we evaluated outcomes using triple intrathecal therapy without cranial radiation (CrRT) for central nervous(More)
In two children with chronic idiopathic thrombocytopenic purpura (ITP) a transient remission of thrombocytopenia was observed after intercurrent measles infection. Both cases were girls who had a long history of thrombocytopenia. During acute measles infection, the delayed hypersensitivity response was suppressed. Total T lymphocytes, T-cell subsets,(More)
Central nervous system (CNS) involvement is not rare in extraocular retinoblastoma, and it is not surprising to find it in view of its route of spread. However, although spinal recurrence presenting as spinal cord compression (SCC) is a form of CNS involvement, it is extremely rare. This report describes two patients with unilateral retinoblastoma with(More)
BACKGROUND The etiology of thrombocytopenia during infancy and early childhood may be different from that of older children, because young children frequently receive vaccines. The following study was performed to understand whether there was a causal relationship between vaccinations and thrombocytopenia. METHODS We retrospectively studied, through chart(More)
Ganglioneuroma is a rare, differentiated, benign and slow-growing tumor that commonly arises from sympathetic ganglion cells. Most of them are asymptomatic and found incidentally. We here report a quite rare case of silent huge ganglioneuroma growing in both posterior mediastinum and retroperitoneum occurring in a 3.5-year-old girl. The patient was(More)
From 1995-1999, a nation-wide study of Langerhans cell histiocytosis (LCH) in children less than 15 years old was conducted by the Taiwan Pediatric Oncology Group. The demographic and clinical data of 55 cases were analyzed. Thirty-two cases presented from the beginning of 1997 to the end of 1998, when the most severe El Niño in the century occurred. The(More)
Renal cell carcinoma is rarely seen in children and adolescents. Patients with widespread disease at diagnosis have a particularly poor survival rate. Currently, all known chemotherapy has been ineffective in improving the median survival in patients with advanced disease. A 13-year-old black boy with stage IV renal cell carcinoma with rhabdoid features is(More)
