The risk of cancer in patients diagnosed with myotonic dystrophy (DM) is reported for the homogeneous Utah population.
Clinical data accessed from the largest Utah healthcare providers have been record-linked to the Utah Population Database, a population-based resource also linked to the Utah Cancer Registry. Relative risks were estimated for 36 cancers of different types in 281 DM patients.
Testicular cancer (relative risk [RR] = 10.74; 95% confidence interval [CI], 1.91-38.79), endometrial cancer (RR = 6.98; 95% CI, 1.24-25.22), and non-Hodgkin lymphoma (RR = 4.25; 95% CI, 1.16-12.43) were all observed at significant excess in DM patients.
This study confirms an overall increased risk of cancer in DM. Individuals diagnosed with DM might benefit from risk counseling.
