INS and endometrial cancer: In a study from Italy by Franchi et al., including 376 diabetic women with endometrial cancer and 7485 diabetic controls matched for cases on age, date at cohort entry and duration of follow-up, no significant associations with EC were observed for insulin at cohort entry (OR = 0.72, 95% CI 0.34–1.56) and at follow-up (OR = 1.19, 95% CI 0.82–1.71).
