Long-term use of lithium and risk of colorectal adenocarcinoma: a nationwide case-control study.

ABSTRACT:

Background

Lithium accumulates in the colon and inhibits the enzyme GSK-3β that possesses anti-carcinogenic effects. We therefore examined the association between lithium use and colorectal cancer risk in a nationwide study.

Methods

We used the Danish Cancer Registry to identify all patients diagnosed with incident colorectal adenocarcinoma during 2000-2012 (n=36 248). Using a matched case-control approach, we estimated the association between long-term use (⩾5 years) of lithium and risk of colorectal adenocarcinoma using conditional logistic regression.

Results

Long-term use of lithium was similar among cases (0.22%) and controls (0.20%), yielding an odds ratio of 1.13 (95% confidence interval (CI), 0.89-1.43) for colorectal adenocarcinoma. Dose-response, subgroup an
