Preoperative serum CRP has been identified as an independent predictor in various malignancies. For osteosarcoma, however, the value of serological markers is unreliable. Aim of this study was to evaluate the prognostic power of preoperative CRP in patients with osteosarcoma. Out of our prospective database, 87 patients with osteosarcoma (43 female, 44 male with an average age of 20.4 years) have been identified with complete documentation of peri-operative CRP-levels, a minimum two year follow-up and after exclusion of concomitant infection, smoking-history or cardio-vascular disease. Pre-operative CRP before tumour resection was correlated with clinical and pathological factors, overall survival and infection rates in an uni- and multi-variate statistical model with and without landmark analysis.Aim
