505P Prediction of mortality in metastatic colorectal cancer in a real-life population based on treatment modality and accompanying clinical parameters

Abstract

Metastatic colorectal cancer still is a lethal disease. Survival, however, is increasing due to rapidly growing treatment options, including systemic and surgical treatment. Due to that and the magnitude of prognostic factors and their unclear interactions, prediction of mortality is difficult but essential for clinical practice inside and outside clinical trials. The aim of the study is to provide a clinical model supporting prognostication at 24 and 36 months for all clinical treatment scenarios (BSC, multimodal treatment, systemic treatment).
