Self-reported family history of leiomyoma: not a reliable marker of high risk

Advancing women's health: The imperative for public health screening of uterine fibroids for personalized care

Uterine fibroids represent the most prevalent genital tract tumours among women, with a disproportionately higher impact on ethnic minority groups, notably black women. These hormonally dependent monoclonal tumours, characterized by excessive extracellular matrix and influenced by genetic, epigenetic, and lifestyle factors, significantly affect women's quality of life and pose substantial economic burdens on healthcare systems. Recent advances in early detection and minimally invasive treatment options have shifted management paradigms towards personalized care, yet challenges in early diagnosis, education and access to treatment persist. This review synthesizes current knowledge on uterine fibroids, highlighting the impact of fibroids on women's health, risk factors, principles of screening, diagnostic tools, and treatment modalities. It emphasizes the importance of early screening and individualized management strategies in improving patient outcomes and reducing healthcare costs. The article also discusses the socio-economic and health disparities affecting the disease burden, underscoring the need for improved patient education, clinician training, and public health strategies to enhance fibroid management. This review proposes a pathway to not only ameliorate the quality of life for women with fibroids, but also to advance global women's health equity.

Family History and Uterine Fibroid Development in Black and African American Women

Importance

Uterine fibroids are an understudied condition, with earlier onset in Black than White women. Prior studies of the importance of family history on fibroid development are limited by reliance on hospital-based participant selection, poorly defined measures of family history, and nonsystematic fibroid assessment.

Objective

To examine whether family history is a risk factor for fibroid development using prospective ultrasonography data to identify incident fibroids and measure fibroid growth and standardized methods to ascertain family history.

Design, Setting, and Participants

This prospective community cohort of Black and African American women from the Detroit, Michigan, area was conducted from January 1, 2010, to December 31, 2018, using 4 standardized ultrasonographic examinations during 5 years to detect fibroids 0.5 cm or larger in diameter and measure fibroid growth. Data analysis was performed between May 2022 and January 2024.

Exposures

Maternal fibroid history data were gathered directly from participants' mothers when possible (1425/1628 [88%]), and 2 exposure variables were created: maternal history of fibroids (diagnosed vs not diagnosed) and age at maternal fibroid diagnosis (20-29, 30-39, or ≥40 years vs not diagnosed).

Main Outcomes and Measures

Fibroid incidence was assessed using multivariable Cox proportional hazards regression models; fibroid growth was calculated as change in log-volume per 18 months for fibroids matched at successive ultrasonograms.

Results

A total of 1610 self-identified Black and/or African American women aged 23 to 35 years (mean [SD] age, 29.2 [3.4] years) with no prior clinical diagnosis of fibroids at enrollment were available for analysis. Of 1187 fibroid-free participants at enrollment, 442 (37%) had mothers who were diagnosed with fibroids. Compared with participants without a maternal history of fibroids, those reporting maternal history had an adjusted hazard ratio (AHR) of 1.21 (95% CI, 0.96-1.52). Risk was strongest in those whose mothers were diagnosed at a younger age (20-29 years: AHR, 1.56; 95% CI, 1.11-2.21; 30-39 years: AHR, 1.03; 95% CI, 0.71-1.49; ≥40 years: AHR, 1.11; 95% CI, 0.81-1.52; P = .053 for trend). Fibroid growth rates were higher when mothers were diagnosed with fibroids vs not diagnosed (8.0% increased growth; 95% CI, -1.2% to 18.0%).

Conclusions and Relevance

In this prospective cohort study, results supported maternal history of fibroids as a risk factor for incident fibroids, especially when mothers were diagnosed at a younger age. Maternal history was also associated with increased fibroid growth. Asking patients about their family history of fibroids could encourage patient self-advocacy and inform care.

The Appropriate Criteria in Patients Selection for Myomectomy in the Era of Minimally Invasive Surgery: A Case Report

Background

Myoma is the most common benign monoclonal neoplasm of the uterus with increased frequency during reproductive years of women.

Case Presentation

A twenty two year old female presented with abdomen lump, dysmenorrhoea, and heavy menstrual bleeding. Multiple myomas were diagnosed based on clinical and radiological findings. Abdominal myomectomy was performed and 75 myomas were enucleated followed by reconstruction of uterus. The second case was a 28 year old married woman presented with heavy menstrual bleeding and dysmenorrhoea. Ultrasound reported single posterior wall myoma of 8×6.3×5.8 cm in size. Laparoscopic myomectomy was performed. At follow-up visit, both cases were completely free of any symptoms.

Conclusion

Myomectomy is a feasible and safe option and a uterine preserving surgery even in the presence of multiple myomas. Setting appropriate criteria in selecting patients for abdominal myomectomy rather than MIS is essential to avoid conversion and associated morbidity.

Immunohistochemical Profile of Uterine Leiomyoma With Bizarre Nuclei; Comparison With Conventional Leiomyoma, Smooth Muscle Tumors of Uncertain Malignant Potential and Leiomyosarcoma

PURPOSE

To assess the immunohistochemical profile of the atypical nuclei in leiomyoma with bizarre nuclei and compare with benign and malignant counterparts.

METHODS

26 cases of uterine smooth muscle tumors including 12 leiomyosarcoma(LMS), 10 leiomyoma with bizarre nuclei (LBN) and 4 smooth muscle tumor with uncertain malignant potential (STUMP) were selected using whole tissue sections for this study and analysis. Six cases of ordinary leiomyoma were included as benign control group. All representative section were stained for P53, Ki67, estrogen receptor and progestrone receptor. Analysis was carried out using SPSS 16.0 for windows software.

RESULTS

Six out of 12 cases of LMS showed strong and diffuse nuclear staining with p53 antibody (50%). In contrast none of STUMPs and only one case of LBN cases showed focal positive reaction with P53. Percentage of positive cells for ki67 in LMS was 14.92 while only 0.85% of cells in LBNs was labeled with Ki67 proliferative marker. (P<0.001). Regarding steroid hormone receptors a significant loosing trend was found in these receptors from benign toward malignant tumors through LBN and STUMP cases.

CONCLUSION

Loss of inhibitory function of wild type P53 gene in leiomyosarcoma is an essential event that discriminate frankly malignant tumors from STUMP and atypical leiomyoma.

Uterine fibroids: pathogenesis and interactions with endometrium and endomyometrial junction

Uterine leiomyomas (fibroids or myomas) are benign tumors of uterus and clinically apparent in a large part of reproductive aged women. Clinically, they present with a variety of symptoms: excessive menstrual bleeding, dysmenorrhoea and intermenstrual bleeding, chronic pelvic pain, and pressure symptoms such as a sensation of bloatedness, increased urinary frequency, and bowel disturbance. In addition, they may compromise reproductive functions, possibly contributing to subfertility, early pregnancy loss, and later pregnancy complications. Despite the prevalence of this condition, myoma research is underfunded compared to other nonmalignant diseases. To date, several pathogenetic factors such as genetics, microRNA, steroids, growth factors, cytokines, chemokines, and extracellular matrix components have been implicated in the development and growth of leiomyoma. This paper summarizes the available literature regarding the ultimate relative knowledge on pathogenesis of uterine fibroids and their interactions with endometrium and subendometrial myometrium.
