Decreasing trend and changing indications of hysterectomy in Finland

Regional practice variation in hysterectomy and the implementation of less invasive surgical procedures: A register-based study in the Netherlands

INTRODUCTION

Many women experience bleeding disorders that may have an anatomical or unexplained origin. Although hysterectomy is the most definitive and common treatment, it is highly invasive and resource-intensive. Less invasive therapies are therefore advised before hysterectomy for women with fibroids or bleeding disorders. This study has two aims related to treating bleeding disorders and uterine fibroids in the Netherlands: (1) to evaluate the regional variations in prevalence and surgical approaches; and (2) to assess the associations between regional rates of hysterectomies and less invasive surgical techniques to analyze whether hysterectomy can be replaced in routine practice.

MATERIAL AND METHODS

We completed a register-based study of claims data for bleeding disorders and fibroids in women between 2016 and 2020 using data from Statistics Netherlands for case-mix adjustment. Crude and case-mix adjusted regional hysterectomy rates were examined overall and by surgical approach. Coefficients of variation were used to measure regional variation and regression analyses were used to evaluate the association between hysterectomy and less invasive procedure rates across regions.

RESULTS

Overall, 14 186 and 8821 hysterectomies were performed for bleeding disorders and fibroids, respectively. Laparoscopic approaches predominated (bleeding disorders 65%, fibroids 49%), followed by vaginal (bleeding disorders 24%, fibroids 5%) and abdominal (bleeding disorders 11%, fibroids 46%) approaches. Substantial regional differences were noted in both hysterectomy rates and the surgical approaches. For bleeding disorders, regional hysterectomy rates were positively associated with endometrial ablation rates (β = 0.11; P = 0.21) and therapeutic hysteroscopy rates (β = 0.14; P = 0.31). For fibroids, regional hysterectomy rates were positively associated with therapeutic hysteroscopy rates (β = 0.10; P = 0.34) and negatively associated with both embolization rates (β = -0.08; P = 0.08) and myomectomy rates (β = -0.03; P = 0.82).

CONCLUSIONS

Regional variation exists in the rates of hysterectomy and minimally invasive techniques. The absence of a significant substitution effect provides no clear evidence that minimally invasive techniques have replaced hysterectomy in clinical practice. However, although the result was not significant, embolization could be an exception based on its stronger negative association.

[Uterine transplantation, ethical and social aspects]

Uterine transplantation is now a possible treatment for absolute uterine infertility. It is currently proposed to women with Mayer-Rokitansky-Küster-Hauser syndrome but indications will likely to expand in the upcoming years. Despite the progressive standardization of the surgical technique and the reduction in perioperative morbidity for both donors and recipients, the number of transplants performed worldwide remains very low compared to the number of women potentially in need. This is partly due to the singularity of uterine transplantation: the uterus is not a vital organ since one can live without a uterus. It is a temporary transplantation that is not performed to extend life but to improve its quality, responding above all to a desire to conceive and bear a child. Beyond the strictly technical aspect, these particularities raise many ethical questions, both on an individual and social level, which should make us question the real place uterine transplantation should take in our society. Answering these questions will allow us to provide better guidance for future eligible couples and to anticipate ethical problems on the long run.

Effect of Test History at Ages 50-64 on Later Cervical Cancer Risk: A Population-based Case-control Study

As life expectancy increases, the effectiveness of cervical cancer screening programs needs to be reassessed for the older population. We addressed the effect of test history in and outside organized screening at age 50-64 years on later cervical cancer risk. A case-control study was conducted by deriving 229 cases of 65-79 years old women with invasive cervical cancer in 2010-2019 from the Finnish Cancer Registry. Ten controls were matched for each case by birth year and hospital district. The effect of test uptake and abnormal results in 50-64 year olds on cancer risk was investigated using conditional logistic regression and adjusted for self-selection. Test uptake within the 50-64 years age group showed 75% lower odds of cervical cancer [adjusted OR (aOR) = 0.25; 95% confidence interval (95% CI), 0.18-0.35]. Untested women had 4.9 times higher odds than those tested with normal results (aOR = 4.86; 95% CI, 3.42-6.92). Having at least one abnormal test result increased the odds by 2.5 when compared with only normal results but showed lower odds when compared with untested women. The importance of testing is exhibited by the result showing a reduction of odds of cancer to one-fourth for those tested compared with untested. Similarly, receiving abnormal results was protective of cancer compared with having no tests highlighting the importance of proper follow-up. Therefore, screening history should be considered when further developing cervical cancer screening programs with special interest in non-attenders and those receiving abnormal results at older ages.

Significance

To our knowledge, this is the first study from Finnish data describing the effect of test history on later cervical cancer at older ages. Focusing on the cervical tests taken within the Finnish national screening program and outside it highlights the overall importance of having cervical tests and adds this study into the slowly increasing number of studies considering all cervical testing in Finland.

Pathologic Profile of Hysterectomy Cases in Saudi Arabia: A Tertiary Center Experience

Background

Hysterectomies are increasingly being replaced by more conservative management modalities and are now only used for limited clinical indications. The agreement between these indications and the final pathology is understudied.

Objectives

This study aimed to correlate the preoperative clinical diagnoses with the pathological findings detected in hysterectomies in Saudi women of different age groups.

Materials and Methods

This retrospective study analyzed the preoperative clinical indications and the subsequent clinical and pathological data of all hysterectomies conducted at a single tertiary care hospital in the Eastern Province of Saudi Arabia between January 2010 and December 2021.

Results

There was no decline in the frequency of hysterectomies across the study period. Abnormal uterine bleeding was the most common clinical indication across all age groups, followed by symptomatic fibroid and uterine prolapse in women aged <50 and ≥50 years, respectively. A total of 9.2% of the cases were indicated for therapeutic reasons, either as an emergency procedure for peripartum hemorrhage or for suspected uterine premalignant and malignant lesions. Besides these, 41.2% of patients had more than one pathology, with the most common combination being leiomyoma and adenomyosis (43.4%). The difference in age between malignant and benign cases (52.3 vs. 48.8 years, respectively) was not statistically significant (P = 0.109).

Conclusions

Most of our cohort had benign lesions. Perceptible misuse of the procedure in this cohort was unlikely, as a large proportion of the patients had more than one pathology corresponding to each clinical indication.

Incidence and determinants of hysterectomy among North Indian women: An 8-year follow-up study

Background

Despite indications of a rapid increase in the number of hysterectomies performed in India, very few studies have methodically investigated the rate and determinants of the incidence of hysterectomy. The present study aims to estimate the rate of incidence of hysterectomy and identify predictors/determinants of incident hysterectomy in a cohort of North Indian women.

Methods

In the present study, a cohort of 1,009 ever-married North Indian women (aged 30-75 years) was followed up after a median of 8.11 years. Those hysterectomized at the baseline (63) were excluded; and of the rest 946 participants, 702 (74.2%) could be successfully followed-up. During the baseline assessment, data about sociodemographic variables, reproductive history, menopausal status, physiological health, and selected blood biochemicals were collected. During the end-line assessment, data about sociodemographic variables, current menopausal status, and incident hysterectomy were recorded.

Results

The overall rate of incidence of hysterectomy was found to be 11.59 per 1,000 women-years, in the study population. Interestingly, the incidence rates were found to be similar among pre- and post-menopausal women. Further, while late age at menarche was found to be negatively associated with incident hysterectomy, folate repletion and high triglyceride (TG) at the baseline were found to be positively associated.

Conclusions

High rate of incident hysterectomy in the studied population points toward the huge burden of gynecological morbidity and the unavailability of non-invasive protocols. Such a situation warrants immediate policy intervention. Further, maintaining TG and folate within normal physiological ranges may be beneficial in gynecological ailments necessitating hysterectomy.

Setting the record straight-Correcting uterine cancer incidence and mortality in the Nordic countries by reallocation of unspecified cases

INTRODUCTION

The incidence of and mortality from cancers of the cervix uteri and corpus uteri are underestimated if the presence of uterine cancers, where the exact topography (site of origin) is not specified, is omitted. In this paper we present the corrected figures on mortality from and incidence of cervix and corpus uteri cancers in the Nordic countries by reallocating unspecified uterine cancer deaths and cases to originate either from the corpus uteri or cervix uteri. To further validate the accuracy of reallocation, we also analyzed how well the reallocation captures the changes occurring as the result of a transition in cause of death coding in Norway that took place in 2005.

MATERIAL AND METHODS

This study uses data available in the NORDCAN database, which contains aggregated cancer data from all the Nordic countries for the years 1960-2016. The unspecified uterine cancer cases and deaths were reallocated to either cervix uteri or corpus uteri based on the estimated probability that follows the distribution of cases and deaths with verified topography. The estimated proportions of cases and deaths for both cancers were calculated for each combination of age group, year, and country as a proportion of cases (and deaths, respectively) with known topography. Annual age-standardized rates were calculated by direct age-adjustment.

RESULTS

The proportions of unspecified uterine cancers were higher in the mortality data than in incidence data, with mean values for 1960-2016 ranging between 5.1% and 26.6% and between 0.2% and 6.8% by country, respectively. In the Nordic countries combined, the reallocation increased the number of cases by 4% and deaths by approximately 20% for both cancers. Finland was the only Nordic country where the mortality rate did not increase substantially after reallocation.

CONCLUSIONS

The reallocation procedure had a significant impact on mortality from cancers of the cervix and corpus uteri for countries where the proportion of cancer deaths coded as uterus, not otherwise specified, is substantial. More effort to validate cause of death data with incidence data from cancer registries is warranted to avoid erroneous conclusions of temporal trends based on uncorrected cancer burden.

Prevalence of Hysterectomy by Self-Reported Disability Among Canadian Women: Findings from a National Cross-Sectional Survey

Introduction: Our objective was to investigate differences in prevalence of hysterectomy by self-reported disability status among Canadian women.

Materials and Methods: We analyzed cross-sectional data from the Canadian Community Health Survey 2012 on 30,170 women aged ≥20 years. Disability was defined as reports of sometimes or often (vs. never) experiencing functional limitations or reduction in daily activities at home, school, or work. Frequency of these limitations was used as a proxy for disability severity. The outcome was self-reported hysterectomy status. Modified Poisson regression was used to quantify the prevalence ratio (PR) and 95% confidence interval (CI) for hysterectomy according to any, functional, or activity-limiting disability, after adjustment for household income, employment, education, ethnicity, and marital status. Results were stratified by age at time of data collection, categorized as childbearing (20–44 years), perimenopausal (45–59 years), and postmenopausal (60 years and older).

Results: Disability was significantly and consistently associated with higher prevalence of hysterectomy in women. The strength of association was inversely related to age category, and PRs for a given age category were similar across disability types and severity levels. PRs for the association between any disability and hysterectomy were 2.18 (95% CI 1.36–3.50) for childbearing-aged women, 1.48 (95% CI 1.21–1.80) for perimenopausal women, and 1.12 (95% CI 1.02–1.24) for postmenopausal women.

Conclusions: Prevalence of hysterectomy is disproportionately higher among women with self-reported disabilities compared with women without disabilities, with these differences most pronounced in women of childbearing age.

Lateral closure of the uterine artery prior to laparoscopic hysterectomy: a systematic review

An alternative surgical technique with closure of the uterine artery at its origin, known as lateral approach prior to TLH, has been proposed and it may offer important benefits to both patients and surgeons. Our objectives were to review the current literature regarding surgical outcomes between lateral and conventional approach in relation to TLH. We followed the 'PRISMA' guidelines and conducted a systematic review, which involved searching PubMed and Embase databases for RCTs evaluating the topic. We identified four RCTs including 585 patients. Three of the four studies reported a significant lower bleeding during TLH with prior lateral approach. Operative time was also shorter in the lateral approach group compared to the conventional approach group in three studies.Our review provides evidence that lateral occlusion of the uterine arteries prior to total laparoscopic hysterectomy may be beneficial due to less blood loss and shorter perioperative time without compromising patient safety.

Current approaches to overcome the side effects of GnRH analogs in the treatment of patients with uterine fibroids

Introduction: Uterine fibroids (UFs) are the most prevalent benign neoplastic threat originating from myometria of reproductive age women, with a profound financial load valued in hundreds of billions of dollars. Unfortunately, there is no curative treatment so far except surgery and available pharmacological treatments are restricted for short-term treatment options. Thus, there is a large unmet need in the UF space for noninvasive therapeutics.Areas covered: The authors reviewed the literature available for the utility of gonadotropin-releasing hormone (GnRH) analogs in women with UFs. We also focused on clinical studies exploring the therapeutic benefits of novel oral non-peptide GnRH antagonists that were recently approved by the U.S. Food and Drug Administration (FDA) in combination with estradiol/norethindrone acetate for the management of heavy menstrual bleeding associated with UFs in premenopausal women.Expert opinion: The results regarding the efficacy of new-generation oral GnRH-antagonists, such as elagolix, relugolix and linzagolix, are promising and offer potential prospect for the future therapy of UFs. However, these antagonists must be combined with hormonal add-back therapy to minimize the resultant hypoestrogenic side effects such as bone loss.
