HD, heart diseases; SMR, standardized mortality ratio.

¹Per 100,000 person-years. Reference population: general US population, 1969–2016.

²Among persons with sarcoma in the populations served by the SEER program.

³Adjusted to the race and sex distributions between patients and the general population.
