PURPOSE To date, the risk factors for central venous port-related bloodstream infection (CVPBSI) in solid cancer patients have not been fully elucidated. We conducted this study in order to determine the risk factors for CVP-BSI in patients with solid cancer. MATERIALS AND METHODS A total of 1,642 patients with solid cancer received an implantable central(More)
