Development of a clinical prediction tool for cancer-associated venous thromboembolism (CAT): the MD Anderson Cancer Center CAT model.

Introduction: Cancer-associated venous thromboembolism (CAT) is a major complication of malignancy. Our goal was to develop a prediction model for VTE that better represented to the population seen at large referral cancer centers.

Materials And Methods: This study was nested in a prospective cohort study at the University of Texas MD Anderson Cancer Center that evaluated adult patients during outpatient cancer-staging computed tomography to estimate the prevalence of incidental VTE.

Primary pulmonary lymphoproliferative neoplasms.

Pulmonary lymphoproliferative neoplasms are rare lung tumors and account for <1% of all lung tumors. Among them, primary pulmonary lymphomas (PPL) constitute the majority, which include Non-Hodgkin's lymphoma (NHL) that comprise of mucosa-associated lymphoid tissue lymphoma, diffuse large B-cell lymphomas and other rare types of NHL and lymphomatoid granulomatosis. HL, which arises secondary to contiguous spread from the mediastinum, is the rarest type of PPL.
