Subsequent Malignant Neoplasms of the Gastrointestinal Tract after Blood or Marrow Transplantation - a BMTSS Report

Background and Purpose: Subsequent malignant neoplasms (SMNs) are a leading cause of non-relapse mortality after blood or marrow transplantation (BMT). Cancers of the gastrointestinal (GI) tract are of special interest since their clinical behavior is often aggressive, but early detection through screening is possible for specific GI malignancies. There is limited information regarding the risk of GI SMNs following BMT. The purpose of this study was to report the risk of GI SMNs after BMT and to identify specific exposures associated with increased risk.
