Comparison of dienogest versus combined oral contraceptive pills in the treatment of women with adenomyosis: A randomized clinical trial

Comparative analysis of the clinical efficacy of conservative treatment for adenomyosis using traditional Chinese medicine and Western medicine

OBJECTIVE

To explore the clinical efficacy of commonly used conservative treatments for adenomyosis using both TCM and Western medicine.

METHODS

210 patients with adenomyosis were selected and divided into 3 groups: Group A (Dan'e Fukang), Group B (Dienogest), and Group C (Goserelin + Mirena), with 70 cases in each group. Afterward, indicators were collected for comparison.

RESULTS

Different treatment approaches exhibited varying effects on uterine VAS, and PBAC among the 3 groups (P < 0.001). The effects of different treatment approaches on serum levels of estradiol (E2), FSH, and CA125 also differed among the 3 groups (P < 0.001). After 3 months of treatment, the incidence of adverse reactions among the 3 groups was significantly different (P < 0.001), with further comparison indicating a lower incidence of adverse reactions in Groups A and B than in Group C (P < 0.017). Meanwhile, statistically significant differences in the incidence of adverse reactions among the 3 groups were observed again after 6 months of treatment (P = 0.004), with further comparison revealing a lower incidence of adverse reactions in Group B than in Group C. Additionally, the comparison of uterine volume (P < 0.001) and VAS (P < 0.001) among the 3 groups was different after 12 months of treatment, and further comparison revealed that the uterine volume was ranked as Group B > Group C > Group A, while the pelvic pain VAS scores were ranked as Group C > Group B = Group A.

CONCLUSION

Dan'e Fukang Decoction is markedly effective in alleviating pain; Goserelin + Mirena exhibits significant efficacy in reducing bleeding.

Efficacy and safety of hormone therapies for treating adenomyosis-associated pelvic pain: a systematic review and network meta-analysis of randomized controlled trials

Background

To date, there are no clear guidelines available on the treatment of adenomyosis-associated pelvic pain (AAPP); however, numerous hormonal treatments (HTs) are currently being used off-label. We conducted a systematic review and network metanalysis with the aim of assessing the efficacy and safety of HTs to reduce AAPP and ranking the available options.

Methods

MEDLINE, LILACS, EMBASE, Scielo.br, PROSPERO, Cochrane Library, conference proceedings, and international registries were searched with no time, region, or language restrictions. Randomized controlled trials that analyzed AAPP in women undergoing HTs were deemed suitable.

Results

Six studies (563 women affected by adenomyosis) were included. At 3 months, women who received a placebo or a levonorgestrel-based intrauterine system (LNG-IUS) experienced more AAPP than those who received dienogest [mean difference of visual analog scale (VAS) pain scores (MD) 4.10 (95% CI 0.49 to 7.71); high evidence; MD 3.05 (95% CI 0.45 to 5.65); high evidence]. At 6 months, women who received dienogest experienced significantly less AAPP compared to those who received combined oral contraceptives [MD -2.85 (95% CI -5.30 to -0.39); moderate evidence], while the prevalence of AAPP was higher among those who received a LNG-IUS than those who received dienogest [MD 1.79 (95% CI 0.06 to 3.53); low evidence].

Conclusion

Dienogest seems to be the most effective HT for AAPP. However, although rare, it is also related to more adverse effects compared to other HTs.

Effects of Deinorgestrel Treatment of Endometriosis on Ovarian Function, Inflammatory Factors, and Pregnancy Rate in Patients

OBJECTIVE

To compare the effects of deinorgestrel and Guizhi Fuling Capsules on ovarian function, inflammatory variables, and the rate of conception in clients receiving endometriosis treatment.

METHODS

Ninety endometriosis patients were divided into the control and test groups. Patients in the control group received oral treatment with Guizhi Fuling Capsules, and those in the test group received oral treatment with Deinorgestrel Tablets.

RESULTS

Compared with the control group, the overall effective therapy rate in the test group was significantly increased. Following the intervention, the test group experienced a considerably larger decrease in interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) levels than the control group. The visual analog scale (VAS ) values for dysmenorrhea, dyspareunia, and non-menstrual lower abdomen discomfort were all considerably lower after therapy than those before therapy. In comparison to the control group, the VAS grades for dysmenorrhea, non-menstrual lower abdomen pain, and sexual intercourse discomfort showed a substantial increase in the test group. Compared with the control group, the 1-year cumulative pregnancy rate in the test group was significant increase in the test group (42.22% (19/45) vs. 64.44% (29/45)).

CONCLUSION

Denogestone significantly alleviates clinical symptoms and body's inflammatory state of Endometriosis patients, without ovarian function damage.

The present adenomyosis treatment status in Luzhou, China: a small scope observational cross-sectional survey

OBJECTIVE

To evaluate the current treatment status and management deficiencies of adenomyosis in Luzhou, China.

MATERIALS AND METHODS

A small-scale observational cross-sectional study of patients whose imaging suggests adenomyosis from July 2018 to February 2022 at a teaching hospital in Luzhou, China. All participants (1542 patients) completed a questionnaire of 14 items, including basic information, symptoms, treatment options, outcomes, and costs. The patients' treatment options and the hysterectomy rate were evaluated.

RESULTS

The treatment options of hormone agents included combined oral contraceptive pills (COCs), gonadotropin-releasing hormone analogues (GnRH-a), levonorgestrel-releasing intrauterine system (LNG-IUS), and dienogest for 2.07, 46.04, 63.49, and 4.67% of patients, respectively. The treatment options under uterus-sparing surgery included adenomyectomy and high-intensity focused ultrasound (HIFU) treatment, presenting in 3.76 and 33.27% of patients, respectively. Finally, 458 (29.70%) patients chose a hysterectomy. The hysterectomy rate between the hormone and uterus-sparing surgery sequential hormone groups (surgery group) was not significantly different (14.8 vs. 12.7%, χ2 = 0.344, P > 0.05). However, for the focal type and patients with > 24 months delayed treatment interval, the hysterectomy rate of the hormone group was significantly higher than that of the surgery group (8.5% vs. 1.3%, χ2 = 11.722, P < 0.01 and 26.7% vs. 18.5%, χ2 = 4.906, P < 0.05, respectively).

CONCLUSIONS

There were treatment delays and treatment selection bias in managing adenomyosis in Luzhou, China. Popular science education and early individualized hormone therapy are needed. Uterine-sparing surgery should be carefully selected.

Dienogest treatment of symptomatic adenomyosis: An in-depth meta-analysis

BACKGROUND

Adenomyosis is a common gynecological disease and a major contributor to dysmenorrhea that substantially reduces the quality of life of the affected. Dienogest has emerged as a promising drug for treating adenomyosis. A few systematic reviews and meta-analyses on this topic have been published recently. However, these meta-analyses were typically based on 2-7 studies, even though numerical data could have been extracted and more studies have been published. Moreover, it is unclear whether there is any characteristic of the patients that is associated with more pronounced improvement after treatment, or which patient subgroup, if any, would benefit most from the dienogest treatment.

OBJECTIVES

To evaluate the efficacy of dienogest in alleviating dysmenorrhea associated with adenomyosis and identifying study/patient characteristics that contribute to a better therapeutic response.

DESIGN

An in-depth meta-analysis incorporating more recent published studies.

METHODS

An in-depth meta-analysis of 14 studies published up to March 2024, involving 637 patients was conducted, using the visual analog scale (VAS) scores on dysmenorrhea severity as the primary outcome measure. Subgroup analyses and multivariable regression were performed to explore potential factors influencing the treatment effect.

RESULTS

Dienogest significantly improved dysmenorrhea, with a mean reduction in VAS scores of 6 on a 10-point scale. Subgroup analyses indicated that dienogest was effective across varying severities of dysmenorrhea and different treatment durations. Notably, patients with higher baseline VAS scores and longer treatment durations experienced greater reductions in VAS scores.

CONCLUSION

Dienogest substantially alleviates dysmenorrhea in women with adenomyosis, particularly among those with severe baseline dysmenorrhea and extended treatment periods. However, variability in patient responses and the potential for adverse effects underscores the importance of individualized treatment strategies. Further large-scale, long-term comparative studies and randomized clinical trials are warranted to optimize treatment outcomes and better understand patient-specific factors.

The First Lugano Workshop on the role of adenomyosis in ART

Adenomyosis is an important clinical condition with uncertain prevalence, and clinical focus on adenomyosis in patients undergoing assisted reproductive technology (ART) has increased during recent years. Recognizing the limited clinical knowledge on the impact of adenomyosis on ART outcomes, the First Lugano Adenomyosis Workshop was a symposium involving experts in the field of adenomyosis, covering basic research, imaging, surgery and infertility to highlight current advances and future research areas over a wide range of topics related to adenomyosis. Adenomyosis is characterized by altered oestrogen and progesterone signalling pathways. Although the criteria of the Morphological Uterus Sonographic Assessment (MUSA) Consortium apply to patients with infertility, the presence of direct signs and localization in the different myometrial layers, particularly the inner myometrium, need more focus. In addition to the MUSA criteria, clinical symptoms and the magnitude of uterine enlargement should also be considered. Whilst pre-treatment with gonadotrophin-releasing hormone agonist with or without an aromatase inhibitor in frozen embryo transfer cycles seems promising, many issues related to therapy remain unanswered. During the Workshop, therapeutic progress over the past decades as well as novel insights were presented and discussed. The role of this opinion paper is to stimulate discussion and spark further interest in adenomyosis and the role of adenomyosis in infertility.

Expert Consensus on the Management of Adenomyosis: A Modified Delphi Method Approach by the Taiwan Endometriosis Society

Objectives

To establish the expert opinions and consensus recommendations from the Taiwanese Endometriosis Society on managing adenomyosis.

Materials and Methods

This study employed a two-round modified Delphi method incorporating a national panel of expert gynecologists to form the consensus on managing adenomyosis. The first round of the Delphi procedure involved an expert panel from the board members to evaluate the relevance of each item. In the subsequent round of votes, gynecologists affiliated with the Taiwan Endometriosis Society participated and used a 5-point Likert scale to cast votes and approve each statement. The rating scales for each item of the key recommendations were analyzed for the distribution of degrees of agreement.

Results

The consensus for managing adenomyosis was developed, encompassing various aspects including imaging diagnosis, hormonal treatment, surgical treatment, noninvasive/minimally invasive treatment, infertility concerns, and obstetric considerations. In the first round of voting, all 25 recommendations received approval from the board members, advancing them to the second round. During the second round of voting, the majority of recommendations received either a "strongly agree" or "agree" response. There was divergence regarding the similarity of effectiveness in alleviating adenomyosis-related pain by either laparotomic or laparoscopic approaches (55% strongly agree or agree vs. 21% disagree or strongly disagree).

Conclusion

The Taiwan Endometriosis Society expert panel has established a set of consensus guidelines for the management of adenomyosis. There are diverging opinions among experts regarding the optimal surgical approaches for resection of adenomyosis.

Evaluation of the therapeutic efficacy of high-intensity focused ultrasound ablation combined with different drugs in the treatment of adenomyosis

OBJECTIVES

To observe the therapeutic efficacy of high-intensity focused ultrasound (HIFU) combined with different pharmacological treatments for adenomyosis.

MATERIALS AND METHODS

A total of 126 patients with adenomyosis who underwent HIFU combined with pharmacological treatment were retrospectively reviewed. Patients were treated with either dienogest (DNG) (Group A, N = 38) or GnRH-a (Group B, N = 88) for three months after HIFU, and received levonorgestrel-releasing intrauterine systems (LNG-IUS) at the end of the third month. Visual Analog Scale (VAS) and Pictorial Blood Loss Assessment Chart (PBAC) scores were used for evaluating symptom improvement.

RESULTS

After propensity score matching (1:2), 38 patients were included in Group A and 76 in Group B. All patients showed significant improvement in VAS and PBAC scores after HIFU, but the PBAC score of Group A was significantly higher than that of patients in Group B at 18 months [11.50 (1.00, 29.50) vs. 0.00 (0.00, 16.50), p < 0.01] and 24 months [4.00 (0.25, 27.75) vs. 0.00 (0.00, 12.75), p = 0.04] after HIFU. Furthermore, patients in Group B had a greater uterine volume reduction at 24 months after HIFU than that of patients in Group A [51.00 (27.00, 62.00) vs. 30.00 (17.00, 42.75, p = 0.02)]. However, the adverse effects in Group A were lower than those in Group B [7 (15.79) vs. 35 (46.05), p < 0.01]. No significant difference was observed in the recurrence rate between the two groups.

CONCLUSIONS

HIFU combined with DNG and LNG-IUS is a safe and effective treatment for patients with adenomyosis.

The use of dienogest in treatment of symptomatic adenomyosis: A systematic review and meta-analysis

Adenomyosis is a gynaecological problem that impacts women's quality of life by causing dysmenorrhea, chronic pelvic pain, and menorrhagia. The search continues for the best medical treatment for symptomatic adenomyosis. This systematic review and meta-analysis investigated the role of dienogest, an oral progestin, in reducing pain and bleeding associated with adenomyosis. Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, MEDLINE, Scopus, and Web of Science were searched in January 2024. The primary outcome was pain scores for dysmenorrhea, whereas secondary outcomes were chronic pelvic pain (CPP), uterine volume (UV), and menorrhagia. One comparison was performed comparing outcomes in symptomatic adenomyosis before and after treatment with dienogest. Pooled analysis of included studies reported a statistically significant reduction of dysmenorrhea pain score after dienogest treatment (mean difference -5.86 cm on a 10-cm visual analogue scale, 95 % CI -7.20 to -4.53, I2 = 97 %). Regarding chronic pelvic pain, a meta-analysis of included studies showed a significant decline in pain after treatment (standardized mean difference -2.37, 95 % CI -2.89 to -1.86, I2 = 60 %). However, uterine volume did not differ significantly after treatment (mean difference -4.65 cm3, 95 % CI -43.22 to 33.91). Menorrhagia was improved significantly after treatment (Peto odds ratio 0.07, 95 % CI 0.03 to 0.18). In conclusion, dienogest seems to be effective in controlling painful symptoms and uterine bleeding in women with adenomyosis at short and long-term therapy.

A systematic review and Bayesian analysis of the adverse effects of dienogest

BACKGROUND AND OBJECTIVE

Endometriosis and adenomyosis are two common diseases that impair women's health, and dienogest is one of the pharmacologic treatments which is the first-line therapeutic option for patients with pelvic pain and individuals who have no desire for immediate pregnancy. The goal of this study was to summarize the current evidence of adverse events associated with dienogest as well as the prevalence of these adverse events during treatment with dienogest.

METHODS

Several databases (PubMed, Embase, Cochrane Central and Clinicaltrials.gov, etc.) and the US FDA Adverse Event Reporting System (FAERS) Public Dashboard were searched on May 31, 2023, using the topic words alongside free words of dienogest and "adverse reaction". Studies were incorporated into this research if they reported or assessed safety issues or adverse reactions of dienogest during the period of endometriosis treatment or adenomyosis therapy. The extracted information comprised trial design, dienogest and control group demographics, as well as reported side effects.

RESULTS

This systematic review comprehended 39 publications in total. The mean age of patients in the included studies was 34.43 years. The follow-up duration varied from 3 to 60 months. Most adverse reactions were common and not serious, and the most common adverse reactions during dienogest medication were abnormal uterine bleeding (55%, 95% CI 37-73%), amenorrhea (17%, 95% CI 2-42%) and swelling (13%, 95% CI 3-28%). Uncommon adverse reactions included dysmenorrhea (0.2%, n = 1), dyspepsia (0.4%, n = 1), and (lower) abdominal pain (1%, 95% CI 0-3%), urticaria (1%, 95% CI 0-3%) and peritonitis (1%, n = 1). Serious adverse reactions including decreased lumbar spine Bone Mineral Density (BMD), depression, peritonitis and so on have been reported. Heterogeneity assessment revealed that patient number and study design are influencing factors to adverse reaction prevalence. Moreover, abdominal pain, diarrhea, nausea and vomiting, back pain and anemia are side effects reported both in the FAERS database and in the systematic review.

CONCLUSIONS

Dienogest's most frequent side effects were not severe. Dienogest is generally safe for treating endometriosis and adenomyosis. Nevertheless, people should be aware of serious adverse reactions, such as decreased lumbar spine BMD and hemorrhagic shock.

The Role of Different Medical Therapies in the Management of Adenomyosis: A Systematic Review and Meta-Analysis

Background/Objectives: Adenomyosis is a benign condition characterized by the presence of endometrial tissue within the myometrium. Despite surgery being a valuable approach, medical options are considered as the first-line approach and have been investigated in the treatment of adenomyosis, although strong evidence in favor of these is still lacking. This study aims to gather all available data and determine the effectiveness of the aforementioned medical options in patients with associated pain and not currently seeking pregnancy, both in comparison to placebo and to one another. Methods: For this study, PubMed and EMBASE were used as data sources, searched up to January 2024. A systematic review and meta-analysis were performed in accordance to guidelines from the Cochrane Collaboration. The primary outcomes investigated were changes in dysmenorrhea, quantified by means of VAS scores, HMB in terms of number of bleeding days, and changes in uterine volume determined at ultrasound. Twelve eligible studies were selected. Results: The results highlighted that dienogest yields a reduction in dysmenorrhea that is significantly superior to that of the rest of the medical treatments investigated (p-value of <0.0002). On the other hand, GnRH agonists seem to play a more prominent role in reducing uterine volume (p-value of 0.003). While it was not possible to determine which medical treatment better decreased the number of bleeding days, it was observed that COC performed significantly worse than the other treatments studied (p-value of 0.02). Conclusions: While this meta-analysis provides valuable insights in the comparative efficacy of different treatments, the paucity of relevant studies on the topic might impact the reliability of some of the conclusions drawn.

Adenomyosis and Abnormal Uterine Bleeding: Review of the Evidence

BACKGROUND

Thomas Cullen described bleeding abnormalities and dysmenorrhea as the "expected" presentations of adenomyomas. Adenomyosis is included within the FIGO classification of structural causes of abnormal uterine bleeding (AUB). Nevertheless, this long-standing association has been questioned by some authors who reported a high incidence of adenomyosis in uteri removed for indications other than AUB or dysmenorrhea. Here, we examine evidence for the link between adenomyosis and AUB.

METHODS

A comprehensive Medline literature review of all publications to October 2023.

RESULTS

Sixty-three articles were identified and included in the review. Despite a large body of studies, the available literature does not provide conclusive evidence of a link between adenomyosis and AUB. This is because of unsuitable study design, or poor characterization of the study population or of the inclusion or exclusion criteria. Additional challenges arise because of the lack of agreed criteria for diagnosing adenomyosis and the often absence of detailed assessment of menstrual blood loss. Adenomyosis often coexists with other conditions that have also been linked to similar symptoms, and many cases of adenomyosis are asymptomatic.

CONCLUSION

Most of the existing literature and studies that addressed treatment outcome of adenomyosis started from the premise that a link between the condition and AUB had been proven. Yet, published information shows that aspects such a relationship is still uncertain. Further research is needed to address the relation between AUB and adenomyosis burden (or subtypes), distribution, and concomitant pathology.

Comparison of efficacy between levonorgestrel intrauterine system and dienogest in adenomyosis: a randomized clinical trial

Background

Medical management of adenomyosis is an emerging perspective in modern gynecology. Though levonorgestrel intrauterine system (LNG-IUS) and dienogest (DNG) effectively relieve symptoms in adenomyosis, neither has been approved for the same indication. Our study aims to compare the efficacy and safety of these progestins in treating adenomyosis.

Objective

To study the efficacy and safety of LNG-IUS versus DNG in patients with symptomatic adenomyosis.

Design

Open-labeled, parallel, single-centered, randomized clinical trial.

Methods

Patients with adenomyosis-associated pain with or without abnormal uterine bleeding were randomly allocated to either LNG-IUS group or DNG group. The primary outcome was a reduction in painful symptoms after 12 weeks of treatment measured by visual analog scale (VAS) score. Changes in menstrual blood loss (MBL), improvement in quality of life (QoL), and adverse drug reactions were also analyzed.

Results

The VAS score significantly decreased from baseline in both groups. The baseline and post-treatment VAS scores in the LNG-IUS group were 6.41 ± 1.07 and 3.41 ± 1.04 (p = <0.001) and in the DNG group, were 6.41 ± 0.95 and 3.12 ± 1.40 (p = <0.001), respectively. A significantly greater proportion of patients in the LNG-IUS group experienced lighter MBL as compared to the DNG group [27/30 (90%) in the LNG-IUS group versus 17/22 (77.2%) in the DNG group (p = 0.006)]. Both the groups had improvement in QOL scores calculated by the World Heath Organisation QOL scale (WHOQOL BREF) questionnaire; however, it was more pronounced in the DNG group [(28.76 ± 30.47 in the LNG-IUS group versus 48.26 ± 44.91 in the DNG group (p = 0.04)]. Both the agents were safe as there were no reported major adverse drug reactions.

Conclusion

DNG can be an effective and safe alternative to LNG-IUS for the medical management of adenomyosis.

Trial registration

The trial was prospectively registered at the clinical trial registry - India (CTRI) vide CTRI number CTRI/2020/05/025186.

Current Medical Therapy for Adenomyosis: From Bench to Bedside

Adenomyosis, characterized by the growth of endometrial tissue within the uterine wall, poses significant challenges in treatment. The literature primarily focuses on managing abnormal uterine bleeding (AUB) and dysmenorrhea, the main symptoms of adenomyosis. Nonsteroidal anti-inflammatory drugs (NSAIDs) and tranexamic acid provide limited support for mild symptoms or symptom re-exacerbation during hormone therapy. The levonorgestrel-releasing intrauterine system (LNG-IUS) is commonly employed in adenomyosis management, showing promise in symptom improvement and reducing uterine size, despite the lack of standardized guidelines. Dienogest (DNG) also exhibits potential benefits, but limited evidence hinders treatment recommendations. Danazol, while effective, is limited by androgenic side effects. Combined oral contraceptives (COCs) may be less effective than progestins but can be considered for contraception in young patients. Gonadotropin-releasing hormone (GnRH) agonists effectively manage symptoms but induce menopausal symptoms with prolonged use. GnRH antagonists are a recent option requiring further investigation. Aromatase inhibitors (AIs) show promise in alleviating AUB and pelvic pain, but their safety necessitates exploration and limited use within trials for refractory patients. This review highlights the complexity of diagnosing adenomyosis, its coexistence with endometriosis and uterine leiomyomas, and its impact on fertility and quality of life, complicating treatment decisions. It emphasizes the need for research on guidelines for medical management, fertility outcomes, long-term effects of therapies, and exploration of new investigational targets. Future research should optimize therapeutic strategies, expand our understanding of adenomyosis and its management, and establish evidence-based guidelines to improve patient outcomes and quality of life.

Nonsurgical management of adenomyosis: an overview of current evidence

PURPOSE OF REVIEW

Adenomyosis is a condition where endometrium-like tissue spreads within the myometrium. Although its prevalence in the general population is not exactly known, its clinical manifestations are well established and include pelvic pain, dysmenorrhea (painful periods), heavy menstrual bleeding and subfertility [1] . Adenomyosis often coexists with other gynaecological conditions, such as endometriosis or fibroids, and may cloud the clinical presentation [2] . The aim of this article is to review current noninterventional, nonsurgical management modalities and wherever possible offer information that allows women to make safe and informed choices regarding their treatment options.

RECENT FINDINGS

Recent studies support that medical strategies, including the Mirena coil, Dienogest and GnRH antagonists, are efficient in improving adenomyosis-associated symptoms. High-quality evidence is scarce and is needed to properly counsel women with this condition. Future research should prioritize overall pain, menstrual bleeding, quality of life and live birth as primary outcomes and assess women with different grades of adenomyosis.

SUMMARY

This review provides the most current evidence with regards to the nonsurgical management of adenomyosis. In light of the paucity and low quality of existing data, high-quality trials are needed to definitely determine the impact of conservative and medical treatment on the clinical management of adenomyosis.

Uterine disorders and iron deficiency anemia

Abnormal uterine bleeding (AUB) is a clinical entity which can lead to iron deficiency anemia. Classification according to the acronym PALM-COEIN (polyp, adenomyosis, leiomyoma, malignancy, and hyperplasia; coagulopathy, ovulatory dysfunction, endometrial, iatrogenic, and not otherwise classified) provides a structured approach to establish the cause of AUB. The goal of this review is to discuss the different mechanisms and the relationship between uterine disorders and AUB. Heavy menstrual bleeding, a subgroup of AUB, is more closely related to the presence of uterine fibroids. The relationship between heavy menstrual bleeding and uterine fibroids remains poorly characterized, particularly the understanding of endometrial function in women with structural myometrial features such as leiomyomas. A number of theories have been proposed in the literature and are discussed in this review. Uterine adenomyosis is also a frequent cause of AUB, and its pathogenesis is still far from being fully elucidated. The mechanisms contributing to its development are multifactorial. Many theories lean toward invasion of the myometrium by endometrial cells. Both clinical and basic studies favor the theory of direct invasion, although de novo development of adenomyosis from Müllerian rests or stem cells has not been ruled out. Development of adenomyotic lesions involves repeated tissue injury and repair. In addition, this review describes the other causes of AUB such as endometrial polyps, cesarean scar defects, and uterine vascular abnormalities. Endometrial polyps are often asymptomatic, but approximately 68% of women have concomitant AUB. Histologic alterations in the lower uterine segment in patients who had undergone cesarean sections were identified and may explain the cause of AUB.

Conservative surgical and drug therapies for adenomyosis Medicine

Adenomyosis is a benign invasion/infiltration of endometrial glands and stroma in the uterine myometrium. The optimal choice of adenomyosis treatment remains a subject of discussion. For patients with adenomyosis without fertility requirements, hysterectomy can be performed by laparotomy or laparoscopic surgery to eliminate symptoms. However, this is an inadequate option for women who want to preserve fertility or avoid more extensive surgery. To summarize the medicine and conservative surgery treatment for adenomyosis. An extensive literature search was performed using PubMed, Web of Science, Embase, Ovid Medline, Cochrane Central Register of Controlled Trials, Google Scholar and China National Knowledge Infrastructure (CNKI) without language restriction. The search terms were as follows: adenomyomas, adenomyosis, conservative therapy; combined therapy; medicine; surgery. The search included all titles and abstracts assessing conservative treatment for adenomyosis including medical and surgical therapy. All published papers were analyzed if considered relevant. Increasing current conservative treatments will not only improve the quality of life of the patients but also preserve fertility. Therefore, conservative treatment is extremely important for patients with fertility requirements or a strong desire to retain the uterus. Conservative treatment for adenomyosis may become a future trend in the field of gynecology.

Conservative Management of Uterine Adenomyosis: Medical vs. Surgical Approach

Uterine adenomyosis is a commonly encountered estrogen-dependent disease in reproductive-age women, causing heavy menstrual bleeding, intense pelvic pain, and infertility. Although adenomyosis was previously considered a disease of multiparous women, it is becoming increasingly evident that it also affects younger nulliparous women and may compromise their fertility potential. It is clear that hysterectomy, the standard approach to definitively manage the disease, is not an option for patients wishing to preserve their fertility, so there is an urgent need to develop novel conservative strategies. We searched the current literature for available methods for conservative management of adenomyosis, including both pharmacological and surgical approaches. There is no existing drug that can cure adenomyosis at present, but some off-label treatment options may be used to tackle disease symptoms and improve fertility outcomes. Adenomyosis in patients wishing to conceive can be 'treated' by conservative surgery, though these procedures require highly experienced surgeons and pose a considerable risk of uterine rupture during subsequent pregnancies. While currently available options for conservative management of adenomyosis do have some capacity for alleviating symptoms and enhancing patient fertility perspectives, more effective new options are needed, with gonadotropin-releasing hormone antagonists showing encouraging results in preliminary studies.

Current and Prospective Treatment of Adenomyosis

(1) Background: Adenomyosis is a poorly understood entity which makes it difficult to standardize treatment. In this paper we review and compare the currently approved medical and surgical treatments of adenomyosis and present the evidence behind them. (2) Methods: A PubMed search was conducted to identify papers related to the different treatments of adenomyosis. The search was limited to the English language. Articles were divided into medical and surgical treatments. (3) Results: Several treatment options have been studied and were found to be effective in the treatment of adenomyosis. (4) Conclusions: Further randomized controlled trials are needed to compare treatment modalities and establish a uniform treatment algorithm for adenomyosis.

Proposal for developing treatment algorithms of women with symptomatic adenomyosis: A single-center experience

AIMS

The most common symptoms of adenomyosis include heavy menstrual bleeding and dysmenorrhea. A variety of medical or surgical techniques are utilized for the treatment of adenomyosis, but there are currently no specific treatment guidelines and best practice recommendations for management. The aim of this study is to summarize current treatment strategies for women with symptomatic adenomyosis in a single-center university hospital in order to provide reliable information for developing treatment algorithms.

METHODS

We conducted an observational cross-sectional study using data from the adenomyosis cohort study from January 2008 to December 2020. Detailed information, including demographic, clinicopathological, and imaging data, were collected from 220 pathologically confirmed patients with adenomyosis.

RESULTS

First, we identified clinical and imaging characteristics in women who underwent surgery or hormone therapy, especially dienogest (DNG) treatment, as first-line treatment. Surgery was generally recommended for multiparous women over the age of 43, especially for patients with intrinsic adenomyosis. Next, we identified the parameters that allowed the continuation of DNG treatment. Oral DNG was given to certain patients with a myometrium thickness of 35 mm or greater and coexisting with endometriosis and/or uterine fibroids. To prevent serious bleeding, DNG treatment can be limited to women with extrinsic adenomyosis with a uterine length of 125 mm or less.

DISCUSSION

Our findings may provide useful information in developing an evidence-based treatment guideline for patients with symptomatic adenomyosis, nevertheless, further investigation is needed for the validation of treatment algorithms.
