participants in this arm will receive the standard of care which in our setting involves the use of either a tourniquet to control intraoperative blood loss especially if the fibroids are large or rarely, other interventions like oxytocin, tranexamic acid, vasopressin and occasionally not using either of the interventions.

The Efficacy and Safety of Preoperative Misoprostol in Blood-loss Reduction During Myomectomy.

Efficacy and Safety of Pre-operative Vaginal Misoprostol in Reduction of Intraoperative Blood Loss During Myomectomy. Amulticentre Single Blind Randomized Trial.

Soaked mops will be weighed and blood loss estimated by subtracting the soaked weight from the dry weight and by multiplying this by 1.060 (average density of human blood is 1.06g/ml); a volume in ml would be acquired. Only mops are intended to be routinely used during the operation for cleaning and clearing the operation field although measurement of blood collected in the suction cylinder in milliliters if used will also be added. Adequate mops will be provided to avoid any spillage onto the operating table polythene sheet. A standardized digital weighing scale will be availed in each operating room. Any spillage onto the bed, however, will be collected in a polythene sheet and poured into a measuring cylinder for quantification.

Procedure is performed under proper analgesia (general or local anesthesia). The intervention can be performed in areas accessible with ultrasound with no critical structures (nerves, vasculature, bowels) in proximity. Limbs and pelvis are most usually accepted locations.
Patient is adjusted on top of the HIFU-transducer connected to MRI. First a MR-scan is performed and the treatment procedure is planned on consol. Then under MRI-guidance a point by point ablation of the target tumor is performed. During the treatment a real-time thermometry is obtained in order to avoid unwanted heating of related structures and to observe sufficient effect on treatment zone. After treatment MR-scan with gadolinium is performed to evaluate the size of ablated area.

Change in Visual analog scale pretreatment vs follow-up

Changes in tumor features pretreatment vs follow-up (signs of progression or regression)

Change in the use of strong opiate-based pain medication intake pretreatment vs follow-up

Change in SF-36 questionnaire pretreatment vs follow-up. SF36 is translated in finnish. It measures several variables related to quality of life ( eg mood, need of help)

Change in serum inflammatory cytokines pretreatment vs follow-up

Change in serum tumor-specific markers (eg. PSA for prostate cancer patients) pretreatment vs follow-up

Possible adverse effects found during treatment or in follow up will be collected and reported

Possible collaboration in the future with Karolinska Institute, Stockholm, during later stages of the study when performing randomized experiments. Data to be shared would be MRI- and CT-data, laboratory results and health-questionnaire results.

Turku University Hospital

Potential participants are recruited by oncologist from oncology outpatient clinic. Pretreatment imaging with computer tomography and magnetic resonance imaging is performed to evaluate whether the patient is eligible for HIFU-treatment. Those eligible will continue to the treatment and unsuitable participants will continue in the study as a control group receiving radiation therapy.
Participants in these groups will have follow-up MRI:s, ct:s, laboratory exams and fill in VAS (visual analog scale) and health questionnaire SF-36 regularly. Also intake of pain medication will be followed.
