{Abstract}: <B>OBJECTIVE: </B>Molecular status of uterine leiomyomas has been shown to affect both tumor characteristics and treatment response. Mutations in mediator complex subunit 12 (MED12), the most prevalent alterations in leiomyomas, are associated with tumor size and number of leiomyomas. Myomectomy can be performed by laparoscopy or by open abdominal surgery, depending on the size and number of leiomyomas removed. The aim of this study was to examine the association between MED12 mutation status and surgical approach of myomectomy. We also evaluated myomectomy patients' quality of life after laparoscopic or abdominal surgery and according to the MED12 mutation status.<BR><B>METHODS: </B>The prospective cohort study included 104 women who underwent laparoscopic or abdominal myomectomy at the Helsinki University Hospital during 2015-2019. Patients filled in the validated Uterine Fibroid Symptom and Quality of Life (UFS-QOL) questionnaire before the operation and 6 and 12 months after the operation. Medical records were reviewed to collect clinical data. Leiomyoma tissue samples were collected and screened for MED12 mutations.<BR><B>RESULTS: </B>Patients undergoing abdominal myomectomy had larger and more numerous leiomyomas compared to patients with laparoscopic myomectomy (10 cm vs 7.4 cm, p < 0.001 and 3 vs 1 leiomyomas, p < 0.001, respectively). A mean change of over 20 points was seen in UFS-QOL scores at 6 months after both laparoscopic and abdominal myomectomy (p < 0.001). MED12 mutations were detected in 178/242 (74 %) of leiomyomas. Of the patients, 45/97 (46 %) had only MED12 positive leiomyomas, while 39/97 (40 %) had only MED12 wild type leiomyomas. The number of leiomyomas removed was higher among patients with MED12 positive leiomyomas than in patients with MED12 wild type tumors (p < 0.001). Laparoscopic approach was equally common in both groups (62 % and 64 %), and there was no statistically significant difference in the UFS-QOL scores.<BR><B>CONCLUSIONS: </B>Both laparoscopic and abdominal myomectomy significantly improved the quality of life. While MED12 mutations were related with multiple leiomyomas and therefore potentially generated a greater leiomyoma burden, they were not associated with the surgical approach. Pre- and postoperative quality of life was comparable between patients regardless of MED12 status.
