Survival rates of cancer patients with and without rheumatic disease: a retrospective cohort analysis.

ABSTRACT:

Background

To compare the outcomes of gastric, colon, lung, and breast cancer patients with and without rheumatic diseases (RD).

Methods

This retrospective study compared the cancer survival rates of a cohort of 122 cancer patients with rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), dermatomyositis/polymyositis (DM/PM), or systemic sclerosis with that of a cohort of 366 age-, sex-, and, cancer type-matched patients without RD who received medical care from 2000 to 2014. Staging, comorbidities, and functional status were ascertained. Survival was compared using the Kaplan-Meier method. Relative risk of death was estimated as a hazard ratio (HR) using Cox regression analysis.

Results

The mean age of the RD patients at the time of cancer diagnosis was 58.
