We have studied the effect of hormone related factors on STS in the Swedish population between 1988 and 2009 using a population-based matched case-control design.RESULTS: Our study is the largest on this topic to date, including 634 cases in a primary matched analysis and 855 cases in an unmatched sensitivity analysis. We identified protective effects connected to constitutional characteristics, hormonal and reproductive factors. Being shorter than your peers at age 11 was associated with an odds ratio (OR) of 0.51 (0.36-0.74). Having used oral contraceptives (OC), OR 0.75 (0.49-1.15), and high parity, OR 0.16 (0.04-0.63), comparing three or more children to two or less, also appeared to reduce the risk of STS. The risk was further reduced with the duration of OC use (p = 0.01), comparing use for 11 years or more to use for 3 years or less yielded an OR of 0.10 (0.02-0.41). No effect was observed for ever having had perimenopausal hormone therapy OR 1.02 (0.70-1.47). The effect of BMI varied significantly with subtype (p = 0.03) and tumor location (p < 0.001).CONCLUSIONS: We observed surrogates of SH, GH, and insulin-like growth factor 1 to be associated with STS development. These findings are important as they may connect STSs to the group of hormone-dependent tumors, potentially revealing common treatment and prevention targets.
