Is myomectomy in women aged 45 years and older an effective option?

Recurrence of Uterine Fibroids After Conservative Surgery or Radiological Procedures: a Narrative Review

The present narrative review aims to discuss the available data on the incidence and the risk factors of uterine fibroids (UFs) recurrence after different types of conservative surgical or radiologic procedures in women wishing to preserve their uterus. UFs are the most common benign tumors in women all over the world. Clinical presentation, including abnormal uterine bleeding (AUB), pelvic pain, bulky symptoms, and infertility affect patients' quality of life, and a large variety of conservative treatments are available especially for those with desire of pregnancy. Fertility sparing surgery, by either laparoscopy, hysteroscopy or laparotomy, or radiological interventions (uterine artery embolization, high-intensity focused ultrasound or magnetic resonance-guided focused ultrasound), are the most common therapeutic approaches. However, the genetic or acquired predisposition to UFs remain despite the treatments, and the recurrences are frequently described in a large percentage of patients. The most relevant risk factors for recurrence of UFs are young age at the first surgery, incomplete fibroid resection, the presence of multiple lesions, an enlarged uterus, and the coexistence with other pelvic diseases. The discussion on the possible medical strategy to reduce the recurrence is an open field of clinical investigation, in particular by using hormonal drugs.

Management of Symptomatic Uterine Leiomyomas: ACOG Practice Bulletin, Number 228

Uterine leiomyomas (fibroids) are the most common solid and symptomatic neoplasm in women. They are the leading indication for hysterectomy (1, 2), which is a definitive and effective surgical treatment for leiomyoma. However, many patients benefit from and seek out management options other than hysterectomy because they desire future childbearing or wish to retain their uterus. The purpose of this Practice Bulletin is to provide updated evidence-based recommendations for the medical, procedural, and surgical management of symptomatic leiomyomas. Discussion of the use of morcellation in the surgical management of leiomyomas is beyond the scope of this document and is addressed in a separate American College of Obstetricians and Gynecologists (ACOG) publication (3).

A prognostic index model for predicting long-term recurrence of uterine leiomyoma after myomectomy

Introduction

Uterine leiomyoma (UL) is a common benign pelvic tumor in women that has a high recurrence rate. Our aim is to propose a prognostic index (PI) model for predicting the long-term recurrence risk of uterine leiomyoma (UL).

Methods

A total of 725 women who underwent myomectomy were enrolled in this retrospective multicenter study. Patients were contacted for follow-up. A PI model was proposed based on the multivariate Cox regression analysis in the model group. The predictive value of this model was tested in both internal and external validation group.

Results

PI formula = 1.5(if 3–5 leiomyomas) or 2(if >5 leiomyomas)+1(if residue)+1(if not submucosal)+1(if combined endometriosis). The PI value was divided into low-risk, intermediate-risk, and high-risk group by cut-off values 1.25 and 3.75. In the model group, the high-risk group had a significantly 4.55 times greater recurrence risk of UL than that in the low-risk group [cumulative recurrence rate (CR): 82.1% vs 29.5%, HR = 4.55, 95% CI 2.821–7.339]; the intermediate-risk group had a significantly 2.81 times greater recurrence risk of UL than that in the low-risk group (CR: 62.3% vs 29.5%, HR = 2.81, 95% CI 2.035–3.878). The differences between any two risk groups were also significant (P< 0.05) in both internal and external validation groups.

Conclusion

The model was proved to be effective in predicting recurrence of UL after myomectomy.

Laparoscopic Intracapsular Myomectomy in Women 40 Years Old and Over with Symptomatic Uterine Fibroids. A Pilot Study

Authors evaluated the impact of laparoscopic intracapsular myomectomy (LIM) in women 40 years of age and over with desire of future fertility compared with medical management of symptomatic fibroids, by a prospective cohort study in University affiliated Hospitals. This study includes a cohort of women 40 years of age and older with symptomatic intramural fibroids with desire of future fertility. Women with symptomatic fibroid uterus were offered to undergo LIM or medical management. They were encouraged to attempt conception either spontaneously or by assisted reproductive technology (ART) according to their individual preference. All women were followed for 2 years. Fibroid characteristics, pre- and post-surgical variables, including surgical complications, days of hospitalization, pregnancy rate, and obstetrical outcomes were collected. A total of 100 patient were included in the analysis. Fifty patients were assigned to the LIM group and 50 to the medical treatment group (MT). Groups were similar regarding age (43.5 ± 2.4 and 43.5 ± 2.4, p  = 0.99), body mass index (23.8 ± 3.1 and 24.2 ± 3.1, p  = 0.54), parity (0.46 ± 0.09 and 0.58 ± 0.09, p  = 0.37), fibroid number (1.38 ± 0.6 and 1.46 ± 0.6, p  = 0.53), and fibroid size (5.92 ± 1.62 cm vs. 5.94 ± 1.49 cm, p  = 0.949). Of the patients who underwent LIM, 62% conceived within the study period compared with 56% in the control group ( p  = 0.54). Pregnancy was achieved by ART in 44% of the patients of the LIM group and 30% in control group. There was no significant difference in pregnancy rates among the two groups regarding spontaneous pregnancy rate ( p  = 0.332), nor in pregnancies obtained by ART with own eggs ( p  = 0.146) and oocyte or embryo donation ( p  = 0.821). The take home baby rate was 65% (20/31) in the LIM group and 61% (17/28) in the control group ( p  = 0.7851). Both groups had similar rate of miscarriage ( p  = 0.748). Patients 40 years old and over with symptomatic fibroid uterus who undergo LIM have similar subsequent fertility and obstetrical outcomes than women treated with medical management. LIM has no detrimental impact on future fertility in women 40 years old and over.

The effects of menopausal uterine fibroids on the prognosis of endometrium cancer

Objective:

This study aimed to evaluate any potential associations between uterine leiomyomas and endometrial cancer.

Materials and Methods:

This is a retrospective study of 153 female patients who have been operated because of endometrial carcinoma in our hospital between 2012 and 2017. Data were collected from hospital records. Study participants were divided into two groups according to the presence and absence of leiomyomas. These two groups were compared in terms of histopathological adenocarcinoma type, nuclear and histological grades, disease stage, para-aortic lymph node involvement, and myometrial invasion. For data analysis, Statistical Package for Social Sciences 15.0 software package was used. Comparison between the two groups was made using the chi-square test, and each variable was tested with the Student’s t-test for statistical significance.

Results:

No statistically significant differences were found between the groups with respect to age, tumor type, myometrial invasion, nuclear grade, or histological grade (p>0.05 for all). A significant difference was found between leiomyomas presence and lymph node metastases. The lymph node metastases were more common in patients without uterine leiomyomas (20.55%) than in those with them (5%; p=0.004). Analysis using the Federation of Obstetrics and Gynecology stages for the presence of leiomyomas indicated that the mean stages were 1A and 1B in patients with and without uterine leiomyomas, respectively (p=0.002).

Conclusion:

Uterine leiomyomas did not adversely affect the prognosis of patients with endometrial carcinoma. Moreover, lymph node involvement was less common, and stages were lower in patients with leiomyomas.

Important considerations for women in the late reproductive and perimenopausal years desiring myomectomy

PURPOSE OF REVIEW

To review important considerations in the counseling and management of women over the age of 40 desiring a myomectomy for symptomatic fibroids.

RECENT FINDINGS

Women in the late reproductive and perimenopausal years may choose a myomectomy over a hysterectomy for reasons of fertility preservation or a personal desire to retain their uterus. Data suggest that laparoscopic myomectomy is a low-risk procedure that can be offered to older women, though the age-related risk of uterine malignancy must be evaluated.

SUMMARY

When assessing the surgical candidacy of older women desiring myomectomy, it is important to weigh a woman's fertility potential, surgical risk, and concerns about malignancy with her desire to preserve the uterus and autonomy to choose a procedure type.

Comparison of 30-day Complication Rates between Laparoscopic Myomectomy and Total Laparoscopic Hysterectomy for the Treatment of Uterine Leiomyoma in Women Older Than Age 40

STUDY OBJECTIVE

To evaluate whether there are differences in complication rates between laparoscopic myomectomy (LM) and total laparoscopic hysterectomy (TLH) for the treatment of uterine leiomyoma in perimenopausal women.

DESIGN

A retrospective cohort study using 1:2 propensity score matching (Canadian Task Force classification II-2).

SETTING

American College of Surgeons National Surgical Quality Improvement Program database.

PATIENTS

Women between the ages of 40 and 60 years undergoing surgical laparoscopic surgery for uterine leiomyoma between the years 2010 and 2016.

INTERVENTIONS

Women were stratified to either LM or TLH at a ratio of 1:2 using propensity score matching. Descriptive statistics were reported as means with standard deviations. Pairwise analysis using the Student t test and chi-square test was performed where appropriate. Multivariable logistic regression was used to identify factors associated with the presence of a complication.

MEASUREMENTS AND MAIN RESULTS

After propensity score matching, there were 631 myomectomies and 1262 hysterectomies. The operating time was slightly longer for LM compared with TLH (166.8 ± 90.3 minutes vs 157.9 ± 70.9 minutes, p = .03). The overall complication rate was 6.3%. There were no differences in complications between the LM and TLH groups (5.9% vs 6.6%, p = .54). Urinary tract infections were more common in the TLH group (2.3% vs 0.6%, p = .01). There were no other differences in the rates of specific complications between the 2 groups. On logistic regression, wound class greater than 3 was most strongly associated with a risk of complications (adjusted odds ratio [aOR] = 8.89; 95% confidence interval [CI], 1.28-15.87). Other variables associated with an increased risk of complications were conversion to hysterectomy (aOR = 5.91; 95% CI, 1.7-9.63), total operating time (aOR = 1.05; 95% CI, 1.02-1.07), and length of stay over 1 day (aOR = 3.67; 95% CI, 2.31-5.8).

CONCLUSION

LM is not associated with an increased risk of complications compared with TLH in women over the age of 40 years undergoing treatment for uterine leiomyomata.

Increased Risk of Venous Thromboembolism in Women with Uterine Leiomyoma: A Nationwide, Population-Based Case-Control Study

Background

Venous thromboembolism (VTE) is a sex-specific disease that has different presentations between men and women. Women with uterine leiomyoma can present with VTE without exhibiting the traditional risk factors. We investigated the relationship between a history of uterine leiomyoma and the risk of VTE using the National Health Insurance Research Database (NHIRD).

Methods

We conducted a retrospective, nationwide, population-based case-control study using the NHIRD. We identified 2,282 patients with diagnosed VTE and 392,635 subjects without VTE from 2000 to 2013. After development of an age and index diagnosis year frequency-matched model and propensity score-matched model, 2 models with a case-to-control ratio of 1 to 4 were established. Using the diagnosis of uterine leiomyoma as the exposure factor, conditional logistic regression was performed to examine the association between uterine leiomyoma and VTE. Multiple logistic regression analysis was used to investigate the joint effect of uterine leiomyoma and comorbid diseases on the risk of VTE.

Results

A strong association was observed between uterine leiomyoma and VTE in the overall patient model, frequency-matched model and propensity score-matched model [p < 0.0001, odds ratio (OR): 1.547; p = 0.0005, OR: 1.486; p = 0.0405, OR: 1.26, respectively]. In the subgroup analyses, women with uterine leiomyoma who were ≥ 45 years old were less likely to experience VTE, but women with uterine leiomyoma and anemia, cancer, coronary artery disease or heart failure were more likely to experience VTE.

Conclusions

Women with uterine leiomyomas have an increased risk of developing VTE, especially during reproductive periods or in the presence of specific diseases.

Outcomes of uterine sarcoma found incidentally after uterus-preserving surgery for presumed benign disease

Background

The aims of this study were to evaluate the impact of initial uterus-preserving surgery, such as myomectomy or subtotal hysterectomy, on the recurrence rates of patients with uterine sarcoma found incidentally and to investigate the role of surgical re-exploration in this disease subset.

Methods

We performed a retrospective chart review for patients who had previously undergone either total hysterectomy or subtotal hysterectomy or myomectomy at the time of initial surgery for presumed benign uterine leiomyoma and were found to have uterine sarcoma on final pathology. Survival analysis was performed comparing patients according to the type of initial surgery.

Results

Between 2006 and 2014, 45 patients with uterine sarcoma were identified. Myomectomy or subtotal hysterectomy was performed in 15 patients, and 30 patients underwent total hysterectomy as the initial surgery. Of the patients who underwent myomectomy or subtotal hysterectomy as the initial surgery (n = 15), 14 were re-explored to complete staging. Of the patients who underwent re-exploration (n = 14), five (35.8 %) had remnant sarcoma on the remaining uterus and no patients had disseminated disease. A Kaplan–Meier curve and log-rank test showed no difference in progression-free survival (P = 0.941) between the two groups.

Conclusion

Initial uterus-preserving surgery does not appear to be associated with an adverse impact on survival outcomes for unexpected uterine sarcoma when surgical re-exploration was performed immediately. As such, surgical re-exploration may be useful for removing any remnant sarcoma.

Clinical and histopathologic predictors of reoperation due to recurrence of leiomyoma after laparotomic myomectomy

OBJECTIVE

To assess clinical and histopathologic risk factors for reoperation after laparotomic myomectomy due to leiomyoma recurrence.

METHODS

A case-control study was conducted of patients who underwent their first myomectomy for leiomyoma without receiving gonadotropin-releasing hormone analogues at Ankara University School of Medicine, Ankara, Turkey, between January 2000 and December 2004. Medical records and histopathologic samples were reviewed, and participants completed a telephone interview. Patients in the case group had undergone reoperation within 5 years; those in the control group had not required further surgery.

RESULTS

There were 51 patients in the case group and 61 controls. The number of women who had given birth after the index surgery was lower among cases than controls (4 [7.8%] vs 13 [21.3%]; P=0.048), as was the median size of the largest leiomyoma removed (4 cm [range 3-10] vs 5 cm [range 3-25]; P=0.009). Reoperation was more likely among patients aged at least 40 years at index surgery (OR 1.10; 95% CI 1.18-7.78; P=0.021) and those with myxoid change (OR 2.04; 95% CI 1.07-55.41; P=0.043). The number of leiomyomas removed was negatively associated with reoperation (OR 0.30; 95% CI 0.58-0.93; P=0.012).

CONCLUSION

Young age, removal of many or large leiomyomas, and pregnancy after myomectomy decreased reoperation risk, whereas myxoid change increased risk.
