Around 7200 cases of Muscle Invasive Bladder Cancer are diagnosed annually in the Nordic countries combined. Muscle Invasive Bladder Cancer is an aggressive disease and it is linked with high mortality rates. The golden standard of treatment is radical cystectomy (RC) (the surgical removal of the bladder) and radical removal of lymph nodes in the pelvis. In addition to surgical treatment, and especially in cases where the tumour invades tissues surrounding the bladder or lymph nodes, chemotherapy is recommended. Chemotherapy can be administered before or after surgery, in a neoadjuvant (NAC) or adjuvant setting (AC). Although most patients recover well from surgery, there are significant risks regarding radical cystectomy. The greatest challenges in planning the treatment are making individual risk assessments and prognosis for the treated patients. Neoadjuvant chemotherapy is also insufficiently used and it is hard to predict how the tumour responds to chemotherapy.
The purpose of this study is to collect prospective clinical data on radical cystectomy -patients in co-operation with other Nordic countries: Sweden, Denmark, Iceland and Norway. The collected data is used to validate existing prediction tools and discover novel tools for prediction of morbidity related to RC and prediction of oncological outcome after RC. The study is divided into three sub-studies. Transfusions during RC and the time of hospitalization after the surgery are associated poorer oncological outcome when compared to those patients who do not need transfusions. The third study focuses on the oncological outcomes in patients receiving blood transfusions. As there are some conflicting reports and the finding is not properly validated, we aim to validate the effect of transfusions on survival after RC.
The number of transfusions during RC and the time between surgery and discharge from hospital will be recorded. Patient cohort will be divided into patients receiving transfusions and not receiving transfusion. The primary end point is patients receiving transfusion and its effect on cancer specific mortality at 24 months. For patients receiving NAC, additional secondary end-point is complete response (pT0N0) rate at RC.
