Chronic toxicity risk after radiotherapy for patients with systemic sclerosis (systemic scleroderma) or systemic lupus erythematosus: association with connective tissue disorder severity

Abstract

No method reliably identifies which patients with connective tissue disorders are at greatest risk of radiotherapy-related complications. Building on our prior experience, we postulated that disease severity, as measured by the number of organ systems involved, may predict chronic radiation toxicity risk.
