Epidemiology and Outcome of Solitary Fibrous Tumors of the Pleura.

Epidemiology and Outcome of Solitary Fibrous Tumors of the Pleura. A Multicenter Study.

1. To determine the incidence, prevalence and long-term outcome of patients with SFTP in the German spoken part of Switzerland.
2. To define the role of immunohistochemical and molecular techniques, such as immunostaining, FISH and mutational analysis regarding their ability to predict malignant behavior in terms of prediction of overall survival and disease-free survival.

Study Overview

• Status: Unknown
• Conditions: Solitary Fibrous Tumors of the Pleura

Detailed Description

Retrospective observational study on patients with SFPT in the German spoken part of Switzerland between 2000 and 2011 (approximately 300 patients):

Phase 1) Information leaflet (letter of invitation) from study center (University Hospital of Zurich) to the institutes for pathology from all university, cantonal and city hospitals in the German spoken part of Switzerland. Patient recruitment performed by medical staff from the aforementioned institutes for pathology.

Phase 2) Obtaining first orally (by telephone) and thereafter written informed consent from the patients performed by medical staff from the aforementioned institutes for pathology.

Phase 3) After written and oral consent has been given, a doctoral candidate (member of the study group, student of the University of Zurich) will perform the data entry based on clinical and histological records locally at each external institute for pathology (no patient record files will be copied or transferred in original to the University Hospital of Zurich). Data entry in the electronic case report from (excel file on study laptop) will be performed with anonymous data only. Hence, each patient will have a study number containing the treating hospital, year of diagnosis and a consecutive number (e.g. KSSG-2011-1, KSSG-2011-2, STZ-2007-1, STZ-2007-2, …). No names or birth dates will appear in the case report form.

Provided that informed consent is given, patient follow-up will be performed by contacting the primary care physician (general physician or family doctor) by telephone, which is handled by the doctoral candidate.

Deceased patients will not be incorporated within the study.

Phase 4) Review of the histological specimen which are collected by the aforementioned doctoral candidate and brought to the University Hospital of Zurich, Institute for Pathology, where immunohistochemical/molecular examinations, such as immunostaining, fluorescence in situ hybridization (FISH) and mutational analysis of the histological specimen are performed by PD Dr. A. Soltermann, member of the study team. After this, the specimens are returned to the original institute for pathology, where they were taken. All specimens are made anonymous at the moment of collection at the external hospital by the doctoral candidate (each specimen is labeled with the aforementioned study number, which is assigned in the case report form).

Phase 5) Data analysis, publication.
