Response to initial treatment of multisystem langerhans cell histiocytosis: An important prognostic indicator

2002

Background Reliable prediction of prognosis allowing risk-adapted therapy remains a major issue in the management of multisystem Langerhans cell histiocytosis (LCH). In a recent publication of the International LCH Study Group, response to initial therapy appears to be a reliable outcome predictor. The aim of this study is to test this observation in a cohort of patients treated with more intensive initial therapy. Furthermore, we compare the predictive value of response to initial therapy to some other well-established stratification systems. Procedure Response to initial combination chemotherapy (prednisolone, vinblastine, and etoposide) at 6 weeks and its prognostic value was evaluated r…

Effective childhood cancer treatment: The impact of large scale clinical trials in Germany and Austria

2013

In Germany and Austria, more than 90% of pediatric cancer patients are enrolled into nationwide disease-specific first-line clinical trials or interim registries. Essential components are a pediatric cancer registry and centralized reference laboratories, imaging review, and tumor board assistance. The five-year overall survival rate in countries where such infrastructures are established has improved from 80% since 1995. Today, treatment intensity is tailored to the individual patient's risk to provide the highest chances of survival while minimizing deleterious late effects. Multicenter clinical trials are internationalized and serve as platforms for further improvements by novel drugs an…

Development and initial validation of the macrophage activation syndrome/primary hemophagocytic lymphohistiocytosis score, a diagnostic tool that dif…

2017

OBJECTIVE: To develop and validate a diagnostic score that assists in discriminating primary hemophagocytic lymphohistiocytosis (pHLH) from macrophage activation syndrome (MAS) related to systemic juvenile idiopathic arthritis. STUDY DESIGN: The clinical, laboratory, and histopathologic features of 362 patients with MAS and 258 patients with pHLH were collected in a multinational collaborative study. Eighty percent of the population was assessed to develop the score and the remaining 20% constituted the validation sample. Variables that entered the best fitted model of logistic regression were assigned a score, based on their statistical weight. The MAS/HLH (MH) score was made up with the i…

Multidisciplinary treatment of primary Ewing's sarcoma of bone.A 6-year experience of a European cooperative trial

1988

The German Society of Pediatric Oncology in 1981 initiated the Cooperative Ewing's Sarcoma Study (CESS 81) using a four-drug combination of chemotherapy prior to definitive local control with surgery and/or radiation. From January 1, 1981 until February 28, 1985, 93 patients were registered at the trial office from 54 participating institutions in West Germany, Austria, Switzerland, and the Netherlands. On February 1, 1987, 54 of 93 patients were disease-free. Using the Kaplan-Meier life table analysis, the estimated disease-free survival (DFS) rate was 60% at 36 months and 55% at 69 months. The median period of observation was 29 months, ranging from 22 months to 69 months. Twenty-one of 9…
