An epidemiological study estimating the burden of cancer risk in patients with Raynaud's phenomenon.

ABSTRACT:

Introduction/objective

Raynaud's phenomenon (RP) is a common vasospastic condition that may develop secondary to cancer and/or in association with systemic autoimmune rheumatic diseases (SARDs). We aimed to estimate the risk of cancer in RP without known SARDs, phenotypically akin to 'primary' RP.

Methods

A cohort study using data from North American electronic healthcare organization records. RP was defined using ≥ 2 ICD (I73.0) codes, excluding SARDs. Comparators had ≥ 2 irritable bowel syndrome ICD (K58) codes: selected with similar epidemiology to RP, and without any known excess in cancer risk. Cohorts were stratified by age (< 45 and ≥ 45 years). Our primary outcome was any cancer event. Secondary outcomes were rates of specific cancers: head and neck, digestive, thora
