- OBJECTIVE: The aims of this study were to create a cohort of retrospectively collected renal cell carcinoma (RCC) specimens to be used a basis for prognostic molecular studies, and to investigate the outcome and time trends in patients surgically treated for RCC in a single-centre cohort.MATERIALS AND METHODS: Patients undergoing surgery for RCC between 1986 and 2010 were included in the study. Medical records were reviewed, and the diagnostic tissue was re-evaluated according to a modern classification. The change in patient and tumour characteristics over time was analysed.RESULTS: The study included 345 patients. Smaller tumours, as indicated by primary tumour diameter, tumour (T) stage and American Joint Committee on Cancer (AJCC) stage, were found more frequently in later years compared to the early 1990s. No changes in the clinical outcome for the patients were seen among the time periods investigated. Increasing T stage, AJCC stage, primary tumour diameter and decreasing haemoglobin levels were associated with cancer-specific mortality in univariate analysis. A high calcium level was significantly associated with increased cancer-specific mortality (hazard ratio = 4.25, 95% confidence interval 1.36-13.28) in multivariate analysis.CONCLUSIONS: This study on patients who underwent surgery for RCC from 1986 to 2010 at a single institution in Sweden indicates that there has been a change in tumour characteristics of patients diagnosed with RCC over time. It was also shown that calcium levels were an independent prognostic factor for cancer-specific mortality in this cohort. This cohort could provide a valuable basis for further molecular studies.

- Purpose: To examine the variation in venous thromboembolism prophylactic treatment (VTEP) among renal cancer patients undergoing surgery.Materials and methods: An Internet-based questionnaire on renal tumor management before and after surgery was mailed to all Nordic departments of urology. The questions focused on the use of VTEP and were subdivided into different surgical modalities.Results: Questionnaires were mailed to 91 institutions (response rate 53%). None of the centers used VTEP before surgery, unless the patient had a vena caval tumor thrombus. Overall, the VTEP utilized during hospitalization for patients undergoing renal surgery included early mobilization (45%), compression stockings (52%) and low-molecular-weight heparin (89%). In patients undergoing open radical Nx, 80% of institutions used VTEP during their hospitalization (23% compression stockings and 94% low-molecular-weight heparin). After leaving the hospital, the proportion and type of VTEP received varied considerably across institutions. The most common interval, used in 60% of the institutions, was for a period of 4 weeks. The restriction to the Nordic countries was a limitation and, therefore, may not reflect the practice patterns elsewhere. It is a survey study and, therefore, cannot measure the behaviors of those institutions that did not participate.Conclusion: We found variation in the type and duration of VTEP use for each type of local intervention for renal cancer. These widely disparate variations in care strongly argue for the establishment of national and international guidelines regarding VTEP in renal surgery.
