Superficial vein thrombosis and its relationship with malignancies: a prospective observational study.

Background: The interrelation of cancer with venous thromboembolism is established, yet the specific impact on the incidence and progression of superficial vein thrombosis (SVT) remains unclear.

Objectives: To investigate the association between SVT and malignancies, focusing on risk factors, presentation, course and complications.

Methods: A single-center prospective observational study of patients diagnosed with DVT or SVT referred to a venous thromboembolism clinic between January 2013 and April 2018.
