Zusammenfassung

Hintergrund

Im Rahmen des Forschungsprojekts „Familiäres Prostatakarzinom“ werden seit 1999 Prostatakarzinompatienten aus ganz Deutschland rekrutiert. Eine umfassende Auswertung der bis dahin rekrutierten 25.065 Familien erfolgte 2009. Davon waren 77,4% sporadisch, 20,0% familiär und 2,6% hereditär betroffen. Oft gelingt es allerdings nicht, umfassende, validierbare Informationen über sämtliche Angehörige zu erhalten.

Ergebnisse

Das hohe Durchschnittsalter der Patienten, die niedrigere Lebenserwartung in der Elterngeneration, sowie eine geringe Zahl an erstgradigen männlichen Angehörigen erschweren die Einteilung in sporadische, familiäre und hereditäre Fälle. Für die Identifikation von 100 hereditären Patienten ist daher in unserer Datenbank die Rekrutierung von mehr als 5000 Patienten und deren Familien notwendig, für 100 sporadische Patienten mit mindestens 2 erstgradigen männlichen Angehörigen, welche anamnestisch kein Prostatakarzinom haben, fast 1250 Patienten.

Abstract

Background

The German national research project“familial prostate cancer” has been recruiting prostate cancer patients nationwide since 1999. In 2009, a comprehensive data analysis of the 25,065 families recruited was performed. Of these, 77.4% were identified as sporadic, 20.0% as familial and 2.6% as hereditary cases of prostate cancer. However, obtaining comprehensive, validated information about all relatives often fails.

Results

The high average age of the patients, the lower life expectancy in further generations and the low number of first-degree male relatives hampers the classification of sporadic, familial and hereditary cases. Consequently we describe here that in our database the identification of 100 hereditary cases requires a recruitment of more than 5,000 patients with their families. For 100 sporadic patients with 2 first-degree male relatives without a case history 1,250 patients are needed.
