Purpose: The purpose of this study was to investigate (a) whether pre-operative serum CRP is a predictor of survival in patients with high-grade osteosarcoma, (b) whether post-operative infection is a predictor of survival in these patients and (c) whether CRP is a predictor of post-operative infection, and especially deep prosthetic infection., Methods: In this retrospective single-centre study, pre-operative serum CRP levels in 79 patients (37 females, 42 males; average age, 18 years; mean follow-up, 46 months) undergoing resection of an osteosarcoma were correlated with clinical data and survival., Results: The mean pre-operative serum CRP level of all 79 patients was 0.53 mg/dl (SD, 1.27 mg/dl). Patients dying of their underlying disease had significantly higher CRP levels compared to patients surviving throughout the follow-up period (1.09 mg/dl ± 2.02 mg/dl versus 0.32 mg/dl ± 0.75 mg/dl, respectively; p = 0.015). CRP levels were significantly correlated with survival (Pearson's correlation coefficient = -0.25; p = 0.026) and histological subtype (Pearson's correlation coefficient = -0.42; p < 0.001), but not with sex, age, histological response, tumour size or metastatic disease. In uni- and multivariate survival analysis, age, response to chemotherapy and serum CRP were associated with disease-specific survival. Patients with a CRP level over 1 mg/dl had a significantly lower disease-specific five-year survival of 36.7% compared to 73.8% in patients with normal CRP values (p = 0.020). Infection was not correlated with disease-specific survival. Pre-operative serum CRP levels were not correlated with post-operative infection or deep prosthetic infection., Conclusions: Pre-operative serum CRP seems to be an independent predictor of survival in patients with high-grade osteosarcoma. Further studies are needed to confirm these results on a large-scale basis.

Objective: The purpose of this study was assessment of the long-term outcome of fibroid-associated quality of life among patients treated with uterine fibroid embolization., Materials and Methods: A retrospective follow-up cohort study included all patients described in a 2006 publication. Analysis was performed with a questionnaire consisting of 49 questions about six topics. Assessment was focused on comparing symptoms and quality of life in long-term follow-up., Results: The analysis was based on questionnaires completed by 39 patients. The median follow-up period was 7 years (interquartile range, 1.5 years). Uterine fibroid embolization led to a reduction of bleeding symptoms in 89.7% of the patients, pain in 78.9%, bulk-related symptoms in 89.5%, fatigue in 76.9%, limitations of social life in 92.9%, and depression in 78.6%. The median impairment scores for bleeding and pain decreased significantly from 7 to 0 and from 5 to 0 (both p < 0.001). The general quality-of-life index increased significantly from 4.5 to 9 (p < 0.001). In the long term, there was no significant difference in parameters assessed compared with the midterm follow-up findings. Six patients (15.4%) underwent hysterectomy an average of 32.1 months after intervention. Thirty-two patients (82.1%) continued to be satisfied with the intervention, and 30 patients (76.9%) answered that they would recommend uterine fibroid embolization to other patients., Conclusion: Uterine fibroid embolization seems to lead to notable long-term relief of fibroid-associated symptoms. In comparison with the midterm results, long-term outcome shows a clear continuance of improvement in general quality of life.
