Prevalence of uterine leiomyomas in lymphangioleiomyomatosis.

ABSTRACT:

Objective

To determine the frequency of uterine leiomyomas and hysterectomy in patients with lymphangioleiomyomatosis (LAM), a disease characterized by proliferation of abnormal-appearing smooth muscle-like cells.

Design

Retrospective study.

Setting

Natural history study at the National Institutes of Health.

Patient(s)

456 patients with sporadic LAM and LAM associated with tuberous sclerosis complex (LAM/TSC).

Intervention(s)

Review of records and pelvic computed axial tomography scans.

Main outcome measure(s)

Prevalence of uterine leiomyomas and hysterectomy.

Result(s)

A total of 174 women had uterine leiomyomas (38%). One hundred eighteen were diagnosed by computed tomographic scan and 56 were diagnosed by hysterectomy. Among 323 patients who did not have hysterectomy, 105 of 270 patients (39%) with sporadic LAM and 13 of 53 (25%) with LAM/TSC had uterine leiomyomas. Hysterectomy was performed in 108 of 378 subjects with sporadic LAM and 25 of 78 with LAM/TSC. Fifty-six patients were found to have uterine fibroids on hysterectomy. The most common indications for hysterectomy were uterine leiomyoma, LAM, and endometriosis.

Conclusion(s)

Uterine leiomyomas are not more common in LAM than in the general population. However, in LAM, the frequency of hysterectomy is higher because of it having been recommended for treatment of LAM.

Project description:BackgroundUterine leiomyomas and adenomyosis are both common and often associated with abnormal uterine bleeding (AUB), including the symptom of heavy menstrual bleeding (HMB). Understanding the prevalence of adenomyosis in women with uterine leiomyomas could inform clinicians and patients in a way that may improve therapeutic approaches.ObjectiveTo explore the prevalence of adenomyosis in a group of women who underwent hysterectomy for AUB-L, to determine the prevalence of submucous leiomyomas, and to examine the utility of preoperative ultrasound to detect the presence of adenomyosis.MethodsThe Kaiser Permanente Hysterectomy Database (KPHD) was searched for women aged 18-52 undergoing hysterectomy for leiomyoma-associated chronic AUB (AUB-L) in 2018 and 2019. A target sample of 400 comprised those with at least 3 years in the Health System. Radiologists evaluated preoperative pelvic ultrasound images to determine leiomyoma size and level 2 FIGO type (submucous or other), and the linked electronic medical record abstracted for clinical features, including histopathological evidence of adenomyosis.ResultsOf the 370 subjects that met the study criteria, adenomyosis was identified via histopathology in 170 (45.9%). There was no difference in the adenomyosis prevalence with (47.1%) and without (43.0%) at least one submucous leiomyoma. Subgroup analysis of ultrasound images by an expert radiologist for the presence of adenomyosis demonstrated a positive predictive value of 54.0% and a negative predictive value of 43.4%.ConclusionsAdenomyosis was present in almost half of this AUB-L cohort undergoing hysterectomy and was equally prevalent in those with and without submucous leiomyomas as determined by sonographic evaluation. The imaging findings are in accord with prior investigators and demonstrate that 2-D ultrasound is insensitive to the presence of adenomyosis when the uterus is affected by leiomyomas. Further research is necessary to determine the impact of various adenomyosis phenotypes on the presence and severity of the symptom of HMB.

Project description:ObjectiveIn the LIBERTY 1 and LIBERTY 2 placebo-controlled trials, once-daily relugolix combination therapy reduced menstrual blood loss volume and pain in women with heavy menstrual bleeding associated with uterine leiomyomas and was well tolerated, with preservation of bone mineral density (BMD) through 24 weeks. Here we report the long-term efficacy and safety of relugolix combination therapy treatment for up to 52 weeks.MethodsWomen with uterine leiomyoma-associated heavy menstrual bleeding who completed any treatment arm in either the LIBERTY 1 or LIBERTY 2 trial were eligible to enroll in a 28-week long-term extension study. All participants received once-daily relugolix combination therapy (40 mg relugolix, estradiol 1 mg, norethindrone acetate 0.5 mg) in the extension study. The primary efficacy endpoint was the proportion of women who achieved or maintained a menstrual blood loss volume of less than 80 mL and a 50% or greater reduction in menstrual blood loss volume from LIBERTY study baseline to the last 35 days of treatment (defined as responders ). Analyses were conducted for all three randomized treatment groups from pivotal studies.ResultsOverall, 477 women enrolled, 476 were treated, and 363 (76.1%) completed 52 weeks. Among patients treated with relugolix combination therapy through 52 weeks (n=163), sustained improvement in heavy menstrual bleeding was observed in 87.7% (responders). The least squares mean menstrual blood loss volume reduction was 89.9%, with 70.6% of patients achieving amenorrhea. At week 52, 59.0% of patients with anemia at baseline had improvements in hemoglobin concentration of greater than 2 g/dL. Distress due to uterine leiomyoma-associated symptoms measured by the BPD (Bleeding and Pelvic Discomfort) scale score was reduced by 51.3 points. Sustained reductions in uterine and uterine leiomyoma volume were observed. Bone mineral density was preserved through week 52.ConclusionImprovements in heavy menstrual bleeding and anemia and reduction of uterine leiomyoma-associated symptom burden were sustained through up to 52 weeks of treatment with relugolix combination therapy in women with uterine leiomyomas. No new safety concerns were identified, and BMD was maintained.Clinical trial registrationClinicalTrials.gov , NCT03049735; NCT03103087; NCT03412890.Funding sourceMyovant Sciences GmbH.
