Significant differences could be observed between the stimulation protocols of sarcoma patients and controls: in particular, lower FSH doses were used in patients cryopreserving oocytes for a sarcoma, compared with patients undergoing COS for assisted reproductive techniques (ART) (1643.7 ± 1168.0 vs. 2001.1 ± 932.0, p = 0.007). This evidence concerns the gene BRD2 and sarcoma.
