In order to investigate miRNA alterations associated to early relapse in ovarian cancer patietns, we analyzed miRNA expression profile in a test set of 30 surgical specimens including 13 early and 17 late relapsing patients. Samples included in test set were obtained from formalin-fixed paraffin-embedded (FFPE) specimens. Overall design: Patients were selected on the basis of residual disease after primary surgery and time to relapse (TTR) after front-line chemotherapy. For the test set, a selection of the outliers concerning TTR was made: 12 months from the end of therapy was the TTR selected to define early (<12 months) or late (>12 months) relapsing patients. Clinical codes: Histotype: according to International Federation of Gynecological and Obstetrics guidelines Stage: according to International Federation of Gynecological and Obstetrics guidelines Grading: according to WHO guidelines Debulking: NED: not evident disease; mRD: minimal residual disease; GRD: gross residual disease Therapy code: P: Platinum without taxanes; PT: Platinum/paclitaxel End Point: Early: relapse whithin 12 and 6 months from the end of therapy for optimally (NED+ mRD) and sub-optimally (GRD) debulked patients respectively. Late: median time to relapse 48 and 34 months from the end of therapy for optimally and sub-optimally debulked patients respectively. Time to relapse (TTR) code: 0=no relapse; 1=relapse Overall survival (OS) code: 0=alive; 1=dead Less...
