Abstract
Introduction and importance Endometriosis is most commonly found in the pelvic area, ~12% of people have it in other areas or organs, which is known as extrapelvic endometriosis. Thoracic endometriosis, which is also classified as extrapelvic endometriosis, manifests with four distinct forms: catamenial pneumothorax, catamenial hemothorax, catamenial hemoptysis, or lung nodules. Catamenial pneumothorax is the most common clinical symptom of these; however, it is frequently neglected by clinicians and goes undiagnosed and untreated. As a result, it is critical to raise awareness of this medical condition among clinicians. Case presentation The authors present a case report of a 34-year-old woman of reproductive age who had recurrent episodes of spontaneous pneumothorax during menstruation and underwent treatment with thoracoscopic surgery as well as gynaecological hormonal drugs including oral progesterone and dienogest throughout this time. Based on her symptoms, a catamenial pneumothorax caused by thoracic endometriosis was suspected. Clinical discussion The clinical symptoms, pathogenesis, diagnosis, and treatment of Catamenial Pneumothorax are analyzed. Furthermore, the usage of gynaecological hormone medications in this condition has been discussed. The mechanisms of oral contraceptives and progestin-based medications are evaluated by comparing the patient's treatment process, highlighting their pros and cons. Conclusions Thoracoscopic surgery combined with postoperative gynaecological hormonal medications may be the most effective treatment for this issue. Several gynaecological hormonal medicines are available, each of which has its own set of pros and cons, and must be thoroughly evaluated as well as correctly tailored to the patient's specific circumstances to have a positive therapeutic outcome.

Abstract
Endometriosis (EM) is a prevalent gynecological disease characterized by the abnormal growth of tissue similar to the endometrium outside of the uterus. This condition is accompanied by the development of new blood vessels in endometriotic lesions. While surgical intervention is effective in removing endometriotic lesions, some patients require multiple surgeries. Therefore, finding non-surgical treatments for EM is of great interest. One of the promising approaches is anti-angiogenic therapy using siRNA-therapeutics to target the expression of the VEGFA gene. Peptide-based polymers have shown promise as siRNA delivery systems due to their biocompatibility and ease of modification. We conducted a study to evaluate the effectiveness of the R6p-cRGD peptide carrier as a non-viral vehicle for delivering siRNA to endothelial cells in vitro and endometrial implants in vivo. We investigated the physicochemical properties of the siRNA-complexes, assessed cellular toxicity, and examined the efficiency of GFP and VEGFA genes silencing. Furthermore, we tested the anti-angiogenic effects of these complexes in cellular and animal models. The transfection with siRNA complexes led to a significant increase in VEGFA gene knockdown efficiency and a decrease in the migration of endothelial cells. For the animal model, we induced endometriosis in rats by transplanting endometrial tissue subcutaneously. We evaluated the efficiency of anti-angiogenic therapy for EM in vivo using anti-VEGF siRNA/R6p-RGD complexes. During this assessment, we measured the volume of the implants, analyzed VEGFA gene expression, and conducted CD34 immunohistochemical staining. The results showed a significant decrease in the growth of endometriotic implants and in VEGFA gene expression. Overall, our findings demonstrate the potential of the R6p-cRGD peptide carrier as a delivery system for anti-angiogenic therapy of EM.

Abstract
Background Endometriosis has a major impact on women's quality of life. The two primary pathologies are chronic inflammation and altered apoptotic activity. Sulawesi propolis has been shown to have known anti-inflammatory and pro-apoptotic properties in other diseases. Objective To investigate the effects of Sulawesi propolis in the rat endometriosis model. Methods An autologous endometriosis model was created in 60 female Wistar rats by laparotomy. Rats were divided into four groups (n = 15 in each group): control group (CG), dienogest group (DG), propolis 50 mg/kg body weight (BW)/day (P50) group, and propolis 100 mg/kg BW/day (P100) group. Each treatment group was divided into three different treatment durations (n = 5 in each treatment group): 2, 4 and 6 weeks. After treatment, laparotomy was performed to determine endometriotic tissue growth, apoptosis [caspase-3 and Bcl-2-associated X/Bcl-2 (Bax/Bcl)] and inflammation [prostaglandin-E2 (PGE2) and interleukin-1B (IL-1B)]. Results A significant difference was seen in endometriotic tissue growth between the P50 group and the CG, with the greatest reduction in the P50 6-week (P50-6) group, reaching 70.66% of the initial area. Highest Bax/Bcl-2 mRNA expression was shown in the P50-4 and P100-4 groups, highest caspase-3 expression was shown in the P50-2 and P50-4 groups, and lowest IL-1B expression was shown in the P50-4 group; all differed significantly from the CG. No significant difference in PGE2S mRNA was found between the groups. Conclusion Sulawesi propolis extract suppressed endometriotic tissue growth in the rat model by increasing apoptotic activity. The effects were time-dependent, with 50 mg/kg BW as the optimal dose.

Abstract
Anti-angiogenic RNAi-based therapy can be considered as a possible strategy for the treatment of endometriosis (EM), which is the most common gynecological disease. Targeted delivery of siRNA therapeutics is a prerequisite for successful treatment without adverse effects. Here we evaluated the RGD1-R6 peptide carrier as a non-viral vehicle for targeted siRNA delivery to endothelial cells in vitro and endometrial implants in vivo. The physicochemical properties of the siRNA complexes, cellular toxicity, and GFP and VEGFA gene silencing efficiency were studied, and anti-angiogenic effects were proved in cellular and animal models. The modification of siRNA complexes with iRGD ligand resulted in a two-fold increase in gene knockdown efficiency and three-fold decrease in endothelial cells' migration in vitro. Modeling of EM in rats with the autotransplantation of endometrial tissue subcutaneously was carried out. Efficiency of anti-angiogenic EM therapy in vivo by anti-VEGF siRNA/RGD1-R6 complexes was evaluated by the implants' volume measurement, CD34 immunohistochemical staining, and VEGFA gene expression analysis. We observed a two-fold decrease in endometriotic implants growth and a two-fold decrease in VEGFA gene expression in comparison with saline-treated implants. RNAi-mediated therapeutic effects were comparable with Dienogest treatment efficiency in a rat EM model. Taken together, these findings demonstrate the advantages of RGD1-R6 peptide carrier as a delivery system for RNAi-based therapy of EM.

Abstract
Endometriosis is an estrogen-dependent disease characterized by the growth of endometrial-like tissue outside the uterus. Progestins are currently the most commonly used treatment for endometriosis because of their excellent therapeutic effects and limited side effects. However, progestins have been unsuccessful in some symptomatic patients. The inability of the endometrium to respond properly to progesterone is known as progesterone resistance. An increasing body of evidence suggests the loss of progesterone signaling and the existence of progesterone resistance in endometriosis. The mechanisms of progesterone resistance have received considerable scholarly attention in recent years. Abnormal PGR signaling, chronic inflammation, aberrant gene expression, epigenetic alterations, and environmental toxins are considered potential molecular causes of progesterone resistance in endometriosis. The general objective of this review was to summarize the evidence and mechanisms of progesterone resistance. A deeper understanding of how these mechanisms contribute to progesterone resistance may help develop a novel therapeutic regimen for women with endometriosis by reversing progesterone resistance.

Abstract
OBJECTIVE To assess the effects of dienogest on segmented in vitro fertilization (IVF) and frozen-thawed embryo transfer (FET) for a patient with adenomyosis. CASE REPORT A 33-year-old female with primary infertility for 3 years had dysmenorrhea and hypermenorrhea. Diagnosis of adenomyosis was made with a sonographic exam and an elevated cancer antigen 125 (CA-125, 310 U/mL). Her early follicular hormone profile (anti-müllerian hormone, AMH, 8 ng/mL) was normal. After repeated controlled ovarian stimulation (COS) and failed intrauterine insemination (IUI), she underwent IVF. Controlled ovarian stimulation using gonadotropin-releasing hormone (GnRH) antagonist protocol was performed with the blastocyst freeze-all IVF cycle. Pretreatment with two months of GnRH agonist (GnRHa) and frozen-thawed embryo transfer did not result in pregnancy. Subsequently, three months of long-term pretreatment with dienogest was given, and the CA-125 level was markedly reduced. Frozen-thawed blastocyst stage embryo transfer was provided, and a singleton pregnancy was achieved. CONCLUSION Dienogest, a novel progestin highly selective for progesterone receptors, may benefit the pregnancy outcomes of infertile patients with adenomyosis adopting segmented IVF with FET.

Abstract
OBJECTIVE To evaluate the efficacy of different hormone therapies in preventing postoperative endometrioma recurrence. DATA SOURCES The MEDLINE, COCHRANE and Embase electronic databases were searched from inception to 30 April 2021. METHODS OF STUDY SELECTION Randomized, controlled trials (RCTs) or cohort studies including reproductive age women with endometriosis undergoing ovarian cystectomy or excision of endometriotic lesions compared the effects of postoperative adjuvant therapy [gonadotropin-releasing hormone agonist (GnRHa)] and postoperative maintenance hormone interventions for more than one year [i.e., oral contraceptive pills (OCPs), dienogest (DNG), levonorgestrel-releasing intrauterine system (LNGIUS)] on endometrioma recurrence . TABULATION, INTEGRATION AND RESULTS Data collection and analysis of the data were independently performed by two reviewers. A total of 11 studies were included, of which 2 were RCTs, and 9 were cohort studies. There were 2394 patients with 6 interventions (cases: 1665, 69.6%) and expectant management (cases: 729, 30.4%). Relative treatment effects were estimated using network meta-analysis (NMA) and ranked in descending order. The clinical effectiveness of these drugs (versus expectant management) was as follows: GnRHa plus DNG [odds ratio (OR), 0.04; 95% confidence interval (CI), 0.01-0.27], surface under the cumulative ranking (SUCRA)= 94.0; DNG (OR, 0.11; 95% CI, 0.04-0.32), SUCRA= 69.7; GnRHa plus OCP (OR, 0.12; 95% CI, 0.02-0.64), SUCRA= 63.4; GnRHa plus LNGIUS (OR, 0.13; 95% CI, 0.03-0.66), SUCRA= 59.4; and OCP (OR, 0.21; 95% CI, 0.13-0.36), SUCRA= 43.6. The effectiveness of GnRHa (OR, 0.47; 95% CI, 0.12-1.89), SUCRA= 17.3 was not significantly different from that of controls. CONCLUSION In NMA, combined postoperative adjuvant therapy and longer maintenance hormone treatment are better than a single agent in preventing postoperative endometrioma recurrence. GnRHa plus DNG maintenance treatment might be the most effective intervention. Large-scale RCTs of these agents are still required.

Abstract
BACKGROUND The quality of life of women with endometriosis is substantially adversely affected by the pelvic pain caused by this disease. However, the choice of medication for endometriosis remains controversial, and no drug has been clearly proven to be superior to others.
AIM To assess the efficacy and safety of dienogest, a synthetic progestin, in the treatment of women with painful symptoms of endometriosis.
METHODS PubMed, EMBASE, the Cochrane Library, and the Web of Science databases were searched from their inceptions to January 21, 2020 for randomized controlled trials (RCTs) that compared dienogest with other popular prescription drugs for the treatment of endometriosis. Two reviewers extracted the data. Mean difference (MD) values and risk ratios (RRs) with 95% confidence intervals (CIs) were calculated.
RESULTS Ultimately, seven RCTs with a total of 1493 participants met the requirements for this review. Dienogest was found to more effective than placebo in alleviating endometriosis-related pain (MD = -32.93, 95%CI: -44.63 to -21.23), but led to a more significant decline in plasma estradiol concentrations than placebo (MD = -44.7, 95%CI: -62.24 to -24.69). Dienogest was superior to gonadotropin-releasing hormone analogues (GnRH-a) in relieving pain (MD = -2.41, 95%CI: -3.58 to -1.24). Moreover, compared with dienogest, GnRH-a were significantly more likely to lead to the loss of bone mineral density (MD = 2.77, 95%CI: 0.16 to 5.37) and were significantly associated with a higher incidence of headaches (RR = 0.68, 95%CI: 0.52 to 0.91) and hot flushes (RR = 0.43, 95%CI: 0.18 to 1.02).
CONCLUSION This meta-analysis demonstrated that dienogest may be a better pain-relief treatment for endometriosis patients, due to its high efficacy and tolerability.

Abstract
Endometriosis requires medical management during a woman's reproductive years. Most treatments aim to create a hypoestrogenic milieu, but for patients wishing to conceive, drugs that allow normal ovarian function are needed. Targeting angiogenesis, a hallmark of the disease, using dopamine agonists (DAs) is a promising strategy for endometriosis treatment. Herein, we review experimental and clinical data that investigate this concept. In experimental models of endometriosis, DAs (bromocriptine, cabergoline, quinagolide) downregulate proangiogenic and upregulate antiangiogenic pathways in inflammatory, endothelial and endometrial cells, blocking cellular proliferation and reducing lesion size. Impaired secretion of vascular endothelial growth factor (VEGF) and inactivation of its receptor type-2 are key events. VEGF inhibition also reduces nerve fiber density in lesions. In humans, quinagolide shows similar effects on lesions, and DAs reduce pain and endometrioma size. Moreover, a 20-fold downregulation of Serpin-1, the gene that encodes for plasminogen activator inhibitor 1 (PAI-1), has been observed after DAs treatment. Pentoxifylline, a PAI-1, increases pregnancy rates in women with endometriosis. Thus, the data support the use of DAs in the medical management of endometriosis to reduce lesion size and pain while maintaining ovulation. A combined approach of DAs and pentoxifylline is perhaps a smart way of targeting the disease from a completely different angle than current medical treatments.

Abstract
Endometriosis is a chronic inflammatory gynecological disorder associated with pelvic pain symptoms and infertility. Ovarian cysts (endometriomas) are the most common localization of endometriosis in the pelvis. Considering non-invasive methods, transvaginal ultrasound has high sensitivity and specificity for endometrioma diagnosis. Laparoscopic removal of endometrioma is related to a damage to the ovarian reserve and should be limited to patients with suspicious cysts or unresponsive to medical treatment. The main goal of medical therapy of symptomatic endometrioma is the control of pain symptoms, while no benefits have been demonstrated in terms of improving fertility rates of women seeking pregnancy. The aim of medical treatment is the inhibition of ovulation, stop of menstruation and achievement of a stable hypo-hormonal milieu. Estroprogestins and progestins are indicated by guidelines as first line medications for symptomatic patients. Several hormonal treatments have been proposed for the treatment of symptomatic endometriomas. In particular, dienogest, a relatively new progestin, has shown promising results. Medical treatment should be conceived as a long-term treatment. Safety, tolerability, a low percentage of side effects and an easy route of administration are essential for patient acceptance and adherence to therapy.

Abstract
Dienogest (DNG) administration is a well-established treatment for endometriosis but bleeding irregularities remain its main disadvantage. Changes in diet, mainly to vegetable consumption, are beneficial in the treatment of estrogen-related pathologies but their use for endometriosis has been poorly studied. In this study, addition of the phytochemical 3,3'-diindolylmethane (DIM) to DNG therapy has been investigated in in vitro and ex vivo models for endometriosis and in a small cohort of women with endometriosis. Endometrial Ishikawa cells were treated with DNG or DIM at dosages from 10-10 M to 10-5 M for up to 72 h. Cell proliferation was measured by assessing BrdU incorporation. Endometrial tissue from women with endometriosis and controls was incubated with DNG or a combination of DNG and DIM. Tissue viability was determined using a modified colorimetric MTS assay. 17β-estradiol secretion was quantified by an electro-chemiluminescence immunoassay. Finally, DNG as monotherapy or in combination with DIM was randomly administered to women with endometriosis (n = 8) over 3 months. Bleeding patterns and associated pelvic pain were assessed by Visual Analogue Scale (VAS). DNG and DIM significantly reduced cell proliferation in Ishikawa cells. Ex vivo, DIM reduced viability and estradiol secretion specifically in endometriotic but not in normal endometrial tissue. This effect was enhanced by combination with DNG. Endometriosis associated pelvic pain was significantly reduced in patients taking the DNG-DIM combination therapy compared to those taking DNG alone. Bleeding pattern (number and duration of episodes) was significantly improved by addition of DIM to the DNG treatment. In conclusion, addition of DIM enhances effects of DNG ex vivo and may ameliorate bleeding patterns in endometriosis patients.

Abstract
Ovarian endometriosis is a common gynecological disorder. To date, progestins are recommended as the first-line medical treatment for symptomatic ovarian endometriosis. The aim of this study was to evaluate the main histopathological effects of short-term dienogest therapy in patients with ovarian endometriomas scheduled for surgery. A prospective, nonrandomized controlled trial, including 70 symptomatic women with single ovarian endometriotic cyst (diameter between 30-50 mm) was conducted. Women scheduled for surgery were divided into two groups, depending on the treatment established at enrollment: 36 women received progestin therapy with dienogest (P group) and 34 women received no therapy (C group). At histopathological examination necrosis, inflammation, decidualization, glandular atrophy and angiogenesis were blindly evaluated. At tissue level, decidualization was significantly more frequent in P group compared to C group (p = .001). A nonsignificant tendency (p = .29) towards a slight decreased inflammation in P group was found. No significant differences were observed between the two groups in terms of necrosis, glandular atrophy and angiogenesis. The study suggests that high decidualization rate and the tendency to reduced inflammatory reaction in the short-term administration of dienogest might contribute to its therapeutic efficacy.

Abstract
INTRODUCTION Endometriosis is a chronic estrogen and progestogen responsive inflammatory disease associated with pain symptoms and infertility. The medical therapy of endometriosis aims to induce decidualization within the hormonally dependent ectopic endometrium, and it is often administered to ameliorate women' pain symptoms or to prevent post-surgical disease recurrence. A variety of progestins have been used in monotherapy for the medical management of women with endometriosis. Areas covered: This review aims to offer the reader a complete overview of pharmacokinetic (PK) and clinical efficacy of progestins for the treatment of endometriosis. Expert opinion: Each progestin has a distinct PK parameters and pharmacodynamics affinity not only for progesterone receptor, but also for other steroid receptors, such as estrogen, androgen, and glucocorticoid. Moreover, progestins can also be delivered in different formulations. All these characteristics influence their final biological effect. Randomized, controlled, non-blinded studies support the use of oral progestin-only treatment for pelvic pain associated with endometriosis. Currently, the only two progestins approved by Food and Drug Administration (FDA) for the treatment of endometriosis are norethindrone acetate (NETA) and depot medroxyprogesterone acetate (DMPA).

Abstract
BACKGROUND Vascularization is a major hallmark in the pathogenesis of endometriosis. An increasing number of studies suggests that multiple mechanisms contribute to the vascularization of endometriotic lesions, including angiogenesis, vasculogenesis and inosculation. OBJECTIVE AND RATIONALE In this review, we provide an overview of the basic mechanisms of vascularization in endometriosis and give special emphasis on their future clinical implications in the diagnosis and therapy of the disease. SEARCH METHODS Literature searches were performed in PubMed for English articles with the key words 'endometriosis', 'endometriotic lesions', 'angiogenesis', 'vascularization', 'vasculogenesis', 'endothelial progenitor cells' and 'inosculation'. The searches included both animal and human studies. No restriction was set for the publication date. OUTCOMES The engraftment of endometriotic lesions is typically associated with angiogenesis, i.e. the formation of new blood vessels from pre-existing ones. This angiogenic process underlies the complex regulation by angiogenic growth factors and hormones, which activate intracellular pathways and associated signaling molecules. In addition, circulating endothelial progenitor cells (EPCs) are mobilized from the bone marrow and recruited into endometriotic lesions, where they are incorporated into the endothelium of newly developing microvessels, referred to as vasculogenesis. Finally, preformed microvessels in shed endometrial fragments inosculate with the surrounding host microvasculature, resulting in a rapid blood supply to the ectopic tissue. These vascularization modes offer different possibilities for the establishment of novel diagnostic and therapeutic approaches. Angiogenic growth factors and EPCs may serve as biomarkers for the diagnosis and classification of endometriosis. Blood vessel formation and mature microvessels in endometriotic lesions may be targeted by means of anti-angiogenic compounds and vascular-disrupting agents. WIDER IMPLICATIONS The establishment of vascularization-based approaches in the management of endometriosis still represents a major challenge. For diagnostic purposes, reliable angiogenic and vasculogenic biomarker panels exhibiting a high sensitivity and specificity must be identified. For therapeutic purposes, novel compounds selectively targeting the vascularization of endometriotic lesions without inducing severe side effects are required. Recent progress in the field of endometriosis research indicates that these goals may be achieved in the near future.

Abstract
Endometriosis is a gynecological condition that affects approximately 10% of women of reproductive age, including 25–40% of infertile women. Dysmenorrhea, dyspareunia and chronic pelvic pain are the most common symptoms. Currently available medical therapies for endometriosis do not cure the disease, but are directed at symptom relief, typically utilizing the hormone responsiveness of endometriotic tissue to induce lesion atrophy. Unfortunately, pain relapse after treatment suspension is a common event. Treatment with pharmacological therapies for endometriosis should be conceived in terms of years, thus agents that must be withdrawn after a few months due to poor tolerability or severe metabolic side effects do not greatly benefit women with symptomatic endometriosis. The characteristics of progestins render this class an ideal pharmacological choice for administration over extended periods. The present paper will review the rationale for using progestins and their mechanism of action in endometriosis. Thereafter, the results obtained by various progestins in the treatment of endometriosis will be evaluated (danazol, gestrinone, norethisterone acetate, desogestrel, cyproterone acetate, megestrol acetate, medroxyprogesterone acetate, and levonorgestrel). A progestin called dienogest, recently introduced for the treatment of endometriosis, will be given special focus, describing its mechanism of action and clinical results.

Abstract
BACKGROUND Dienogest is a progestin with demonstrated efficacy in the treatment of endometriosis in European women. The objective of this study was to evaluate the efficacy and safety of dienogest in Chinese women. PATIENTS AND METHODS This 24-week, randomized, double-blind, placebo-controlled multicenter (n = 23) study evaluated the efficacy and safety of 2 mg dienogest once daily in 255 Chinese women aged 18-45 years with laparoscopically diagnosed endometriosis and an endometriosis-associated pelvic pain (EAPP) score ≥30 mm on a 0-100 mm visual analog scale. The primary efficacy variable was absolute change in EAPP from baseline to week 24. Secondary efficacy variables included proportions of responders and intake of supportive analgesic medication. Safety variables included adverse events (AEs), laboratory parameters, and bleeding patterns. Bone mineral density (BMD) was evaluated in a subset of 140 women. RESULTS After 24 weeks of treatment, the difference between treatment arms for mean reduction in EAPP was statistically significant in favor of dienogest (-24.54 mm; 95% CI -29.93 to -19.15; p < 0.0001). Secondary efficacy analyses supported the significant superiority of dienogest over placebo. Dienogest was well tolerated, with few AEs associated with therapy. Dienogest had no effect on BMD levels after 24 weeks of treatment. CONCLUSIONS Dienogest 2 mg once daily for 24 weeks was superior to placebo in reducing EAPP and was safe and well tolerated in Chinese women with endometriosis. The results are consistent with studies previously conducted in European women.

Abstract
OBJECTIVES To evaluate the in vivo effect of dienogest on proliferation, apoptosis, aromatase expression, vascular density, nerve growth factor (NGF) expression and nerve fiber density in human adenomyosis tissue. STUDY DESIGN Twelve women who underwent hysterectomy for adenomyosis were enrolled. Six patients received dienogest treatment prior to hysterectomy (dienogest group), and age-matched six patients who had not received any hormonal treatment for ≥3 months before surgery (control group). Cell proliferation, vascular and nerve fiber density in adenomyosis tissue were evaluated by staining for Ki67, von Willebrand factor and PGP9.5, respectively. Apoptosis was detected using the TUNEL assay. The expression aromatase and NGF were evaluated by staining for corresponding antibodies. RESULTS The proportion of Ki67 positive epithelial cells was significantly lower in samples from dienogest-treated patients in comparison with controls (p<0.05). The density of blood vessels in adenomyosis was marginally lower in the dienogest group in comparison with controls but statistical significance was not reached (p=0.07). The intensity of NGF expression and the density of nerve fibers were significantly lower in the dienogest group compared with controls (p<0.05 for both). CONCLUSION This study demonstrates that adenomyosis, taken from patients treated with dienogest, shows remarkable histological features, such as reductions in proliferation, NGF expression and nerve fiber density. These findings indicate the impact of dienogest on local histological events, and explains its therapeutic effect on adenomyosis.

Abstract
OBJECTIVE As the number of younger women with endometrial carcinoma has increased, fertility-sparing treatments have received more attention. Although there have been several reports on conservative treatments with progestins for endometrial carcinoma, only medroxyprogesterone acetate (MPA) is available in Japan. Dienogest has been developed as a fourth-generation progestin for treating endometriosis. Because of its high progesterone activity, its antitumor activity has attracted attention. In this study, we investigated the anticancer effect of dienogest on endometrial neoplasms using mouse model of endometrial carcinoma. METHODS/MATERIALS Pten(loxP/loxP) mice were injected with MPA or dienogest subcutaneously to evaluate the anticancer effect against endometrial neoplasms that developed in the mice. One week after injections, histopathological analyzes were performed. RESULTS Endometrial neoplasms were found in one of the eight (12.5%) mice from each group treated with either dienogest or MPA. In contrast, they were found in seven of eight (87.5%) mice not treated with progestins. Each progestin treatment showed anticancer activity against endometrial neoplasms that developed in the mice compared to those without treatment. CONCLUSIONS Dienogest and MPA showed potent anticancer activity against endometrial neoplasms in our mouse model. The present study demonstrated that dienogest might be a useful therapeutic agent for human endometrial neoplasms.

Abstract
OBJECTIVE AND DESIGN A systematic review of all literature was done to assess the ability of the progestin dienogest (DNG) to influence the inflammatory response of endometriotic cells. MAIN OUTCOME MEASURES In vitro and in vivo studies report an influence of DNG on the inflammatory response in eutopic or ectopic endometrial tissue (animal or human). RESULTS After strict inclusion criteria were satisfied, 15 studies were identified that reported a DNG influence on the inflammatory response in endometrial tissue. These studies identified a modulation of prostaglandin (PG) production and metabolism (PGE2, PGE2 synthase, cyclo-oxygenase-2 and microsomal PGE synthase-1), pro-inflammatory cytokine and chemokine production [interleukin (IL)-1β, IL-6, IL-8, tumor necrosis factor-α, monocyte chemoattractant protein-1 and stromal cell-derived factor-1], growth factor biosynthesis (vascular endothelial growth factor and nerve growth factor) and signaling kinases, responsible for the control of inflammation. Evidence supports a progesterone receptor-mediated inhibition of the inflammatory response in PR-expressing epithelial cells. It also indicated that DNG inhibited the inflammatory response in stromal cells, however, whether this was via a PR-mediated mechanism is not clear. CONCLUSIONS DNG has a significant effect on the inflammatory microenvironment of endometriotic lesions that may contribute to its clinical efficacy. A better understanding of the specific anti-inflammatory activity of DNG and whether this contributes to its clinical efficacy can help develop treatments that focus on the inhibition of inflammation while minimizing hormonal modulation.

Abstract
Angiogenesis and inflammation are pivotal processes in developing endometriosis in the peritoneal cavity. The aim of the present study was to evaluate these two processes in women with endometriosis who had been treated with danazol to determine the sensitivity of a non-invasive test in diagnosing endometriosis. The clinical follow-up study was conducted in a group of 103 women diagnosed laparoscopically with endometriosis. Thirty-five patients qualified for danazol treatment. Pain was assessed using a visual analogue scale, whereas endometriosis was assessed using the revised American Society of Reproductive Medicine (rASRM) scale. Cancer antigen (CA)-125 and C-reactive protein (CRP) concentrations in plasma and peritoneal fluid were determined by immunoenzymatic methods, whereas vascular endothelial growth factor (VEGF) and interleukin (IL)-1β concentrations in plasma and peritoneal fluid were determined by ELISA. Endometrial expression of IL-8 and platelet-derived growth factor alpha polypeptide (PDGF-A) was determined using real-time polymerase chain reaction (PCR). Women with endometriosis (68.9% of patients) had higher plasma concentrations of CA-125, as well as higher concentrations of both CA-125 and VEGF in the peritoneal fluid. Endometrial expression of IL-8 mRNA was significantly higher, whereas that of PDGF-A was significantly lower, in contrast. After danazol treatment the patients reported lower pain scores; in addition, CA-125 concentrations in the plasma were decreased (P<0.001), whereas VEGF concentration in the plasma increased (P=0.009). For the diagnosis of endometriosis, none of the combinations of given markers had a sensitivity >60%. Danazol treatment is highly effective in relieving pain and decreasing CA-125 concentrations in the plasma. Higher plasma concentrations of VEGF after treatment could imply stimulation of angiogenesis.

Abstract
OBJECTIVE The progestin dienogest (DNG) given alone effectively reduces pelvic pain of women with endometriosis. It is not clear whether the same occurs when DNG is associated with estradiol (E2). DESIGN Patient preference prospective observational study. SETTING Outpatient centre of university hospital. PATIENTS 40 patients with endometriosis and menstrual pain. INTERVENTIONS 24-week treatment with a quadriphasic association of E2 valerate (E2V) and DNG or a nonsteroidal anti-inflammatory drug (NSAID) to be used only in case of pain (ketoprofene 200-mg tablets). MAIN OUTCOME MEASURES Menstrual pain and, when present, intermenstrual pain, and dyspareunia were investigated by means of a 10-cm visual analogue scale (VAS). Quality of life was investigated by the short form 36 (SF-36) of the health-related quality of life questionnaire. RESULTS Final study group consists of 34 patients, 19 in the E2V/DNG group and 15 in the NSAID group. After 24 weeks, no significant modification of menstrual pain, intermenstrual pain, dyspareunia, or SF-36 score was observed in the NSAID group. Treatment with E2V/DNG reduced the VAS score of menstrual pain by 61% (P < .0001). In the subgroups of women with intermenstrual pain or dyspareunia, E2V/DNG reduced these complaints by 65% (P = .013) and 52% (P = .016), respectively. The reduction in menstrual (P = .0001) and intermenstrual pain (p = 0.03) was significantly greater during E2V/DNG than NSAID. Quality of life improved during E2V/DNG (P = .0002), both in physical (P = .0003) and mental domains (P = .0065). Only a few minor adverse effects were described during E2V/DNG, and none caused withdrawal from treatment. CONCLUSION In patients with endometriosis and pelvic pain, the 24-week administration of the quadriphasic association of E2V/DNG decreases pelvic pain and improves quality of life.

Abstract
Dienogest is a novel progestin that is highly selective for progesterone receptors and inhibits endometriosis. However, it remains unknown how the administration of dienogest to patients with endometriosis impacts on their lesion tissues. The aim of this study was to evaluate the in vivo effect of dienogest on endometriosis tissue. We collected endometrioma tissues from patients treated with dienogest (N = 7) or not treated (N = 11, controls). Cell proliferation, aromatase expression and blood vessel density were evaluated by staining for Ki67, aromatase and the von Willebrand factor, respectively. Apoptosis was detected using the TUNEL assay. The proportion of Ki67 and aromatase positive epithelial cells was significantly lower in the dienogest group than in controls (p < 0.05, respectively). The number of TUNEL positive cells was significantly higher in the dienogest group (p < 0.05). The density of blood vessels in endometrioma was marginally lower in the dienogest group compared with controls (p = 0.20). Our study demonstrates that endometrioma taken from patients treated with dienogest show remarkable histological features such as reduction of proliferation, aromatase expression and angiogenesis, and increase of apoptosis. This study clarified the impact of dienogest on local histological events that explain its therapeutic effect on endometriosis.

Abstract
We have reported an inhibitory effect of Lactobacillus gasseri OLL2809 (OLL2809) on the growth of mouse endometrial tissue in the abdominal cavity. The present study aimed to investigate the efficacy of Lactobacillus gasseri OLL2809 (OLL2809) on pre-existing endometriosis implanted on the abdominal wall in diestrus Wistar-Imamichi female rats. One week after implantation, the volume of the endometrial tissue was measured after laparotomy. OLL2809 and dienogest were administered for 4 weeks. OLL2809 significantly enhanced the decrease in the volume (p<0.01) as compared with control. Complete healing was observed in two of nine rats, but in none of the control group. Dienogest did not show significant efficacy. These findings suggest that OLL2809 is useful not only in therapy of pre-existing endometriosis but also in the prevention of the growth of endometrial tissue.

Abstract
Endometriosis is a gynecological disease characterized by the growth of endometrium outside of the uterine cavity. It is often associated with dysmenorrhea, dyspareunia, pelvic pain and infertility. One of the key requirements for endometriotic lesions to survive is development of a blood supply to support their growth. Indeed, dense vascularization is characteristic feature of endometriotic lesions. This has led to the idea that suppression of blood vessel growth (anti-angiogenic therapy) may be a successful therapeutic approach for endometriosis. Potential effectiveness of anti-angiogenic therapies has been assessed in some animal models but there are no reports of human clinical trials. Without understanding the specific mechanism by which endometriosis lesions establish a new blood supply, short-term animal experiments will have limited value for translation into human medicine. Further, it is crucial to use appropriate animal models to assess efficacy of anti-angiogenic compounds. Syngeneic and autologous rodent models, where endometrial fragments are auto-transplanted into the peritoneal cavity are commonly used in anti-angiogenic therapy studies. Another approach is xenograft models where human endometrium is engrafted into immunodeficient mice. Here we review the animal models and experimental techniques used to evaluate anti-angiogenic therapies for endometriosis. We also review our own work on the role of stromal cell derived factor-1 in the recruitment of endothelial progenitor cells in endometriotic lesion angiogenesis, and the effects of the anti-angiogenic peptide ABT-898, a thrombospondin-1 mimetic, on endometriotic lesion growth and vascular development.

Abstract
Angiogenesis is a prerequisite for endometriotic lesion formation and development. Pigment epithelium-derived factor (PEDF) is a potential inhibitor of angiogenesis. The objective of this study was to detect PEDF immunolocalization in endometriotic lesions and the correlation with vascular endothelial growth factor (VEGF) and microvascular density (MVD) in a rat model of endometriosis. A subcutaneous endometriosis rat model was established by using auto-transplantation. Expression of PEDF, VEGF and MVD labeled by von Willebrand factor (v-WF) in endometriotic lesions and endometrial tissues was evaluated using immunohistochemical staining. We detected lower PEDF immunostaining and higher VEGF and MVD immunostaining in active lesions in a rat model of endometriosis than that in endometriosis endometrium or control endometrium (P<0.05), but no differences between endometriosis and control endometrium were found (P>0.05). In lesions, PEDF expression was negatively correlated with VEGF expression, MVD or sizes of cysts (P<0.01). On the contrary, both VEGF expression and MVD were positively correlated with lesion sizes (P<0.05). In addition, VEGF expression was positively correlated with MVD (P<0.01). Our results suggest that PEDF might be involved in the pathogenesis of endometriosis and may lead to novel treatment for this disease.

Abstract
Cases of endometrial cancer have increased in recent years, but the prognosis of patients with this disease has also been improved by combined modality therapy with surgery, radiotherapy and chemotherapy. However, the development of new therapy is required from the perspectives of conservation of fertility and efficacy for recurrent and intractable cancer. New candidate therapeutic agents for endometrial cancer include fourth-generation progestins for inhibition of growth and differentiation of endometrial glands; metformin for reduction of hTERT expression in the endometrium and inhibition of the mTOR pathway by activation of AMPK, with consequent inhibition of the cell cycle; mTOR inhibitors for supressing growth of cancer cells by G1 cell cycle arrest; microRNAs involved in the molecular mechanisms of oncogenesis and progression; and HDAC inhibitors that block the growth of cancer cells by transcriptional elevation of tumor-suppressor genes, cell cycle arrest and induction of apoptosis. In this study, we review the background and early clinical evidence for these agents as new therapeutic candidates for endometrial cancer.

Abstract
Approaches to the treatment of endometriosis vary worldwide, but studies comparing endometriosis medications in different ethnic groups are rare. A systematic literature search identified two studies directly comparing dienogest (DNG) versus gonadotropin-releasing hormone (GnRH) analogues in European and Japanese populations. Meta-analysis of visual analogue scale scores revealed no heterogeneity in response between the trials, indicating equivalent efficacy of DNG and GnRH analogues for endometriosis-related pain across populations. DNG was significantly superior to GnRH analogues for bone mineral density change in both trials, but significant heterogeneity between the studies may indicate ethnic differences in physiology.

Abstract
Dienogest offers pharmacological advantages for the effective treatment of endometriosis and for use in contraception and hormone replacement therapy. This pharmacodynamic study investigated the ovulation-inhibiting effects of dienogest monotherapy in healthy women. Dienogest was administered at 0.5, 1, 2, or 3 mg daily for up to 72 days to women aged 18 to 35 years (n = 102). Ovarian activity was assessed pretreatment and during 2 treatment periods (days 0-36 and days 37-72) by the Hoogland score, based on follicle size and serum estradiol and progesterone levels. Additional hormonal parameters and endometrial thickness were assessed. Hoogland scoring indicated ovulation in all women pretreatment, decreasing to 3 of 21, 1 of 23, 0 of 20, and 0 of 23 women in the 0.5-, 1-, 2-, and 3-mg groups, respectively (per-protocol set). Maximum serum estradiol concentrations were similar to pretreatment levels in the 0.5- or 1-mg group and decreased moderately (within physiologic levels) in the 2- or 3-mg group. Endometrial thickness was reduced by all dienogest doses. Hormonal changes during follow-up indicated resumption of ovulation in most women, shortly after treatment cessation. Dienogest ≥2 mg daily provides moderate suppression of estradiol production and reliable ovulation inhibition, which reverses rapidly after treatment cessation.

Abstract
BACKGROUND Dienogest demonstrates efficacy for lesion reduction and pain relief in clinical trials of endometriosis. The current study investigated an intraperitoneal animal model of endometriosis to further characterize the effects of dienogest. METHODS Endometrial-like lesions were induced in rats by autotransplantation of uterine tissue into the peritoneal cavity. Dienogest 0.3 or 1.0 mg/kg/day, danazol 100 mg/kg/day, or vehicle control were administered orally for 28 days. Changes in endometrial-like lesion size during treatment were assessed at laparotomy. Uterine horn weight was also measured as an index of the estrogenic effects of treatment. RESULTS Dienogest 0.3 mg/kg/day significantly reduced the total endometrial lesion area, with an effect equivalent to danazol 100 mg/kg/day. Unlike dienogest 1.0 mg/kg/day, dienogest 0.3 mg/kg/day had no effect on uterine horn weight, indicating an absence of estrogenic effects for this dose in rodents. CONCLUSION Dienogest 0.3 mg/kg/day for 28 days demonstrated potent inhibitory activity on the growth of endometrial tissue in this model, providing supportive evidence for the efficacy of dienogest in lesion reduction.

Abstract
Endometriosis is a chronic disease primarily affecting women of childbearing age, in which endometriotic lesions form outside the uterus, typically leading to painful symptoms, fatigue, and infertility. The symptoms of endometriosis may cause significant impairment in quality of life and represent a substantial economic burden to patients, families, and society. There is no cure for endometriosis; management consists of alleviating pain and other symptoms, reducing endometriotic lesions, and improving quality of life. Recurrence after surgical intervention is common, while the clinical evidence to support the efficacy and safety of many medications currently used in endometriosis is limited. Dienogest is an oral progestin that has been investigated extensively in the treatment of endometriosis in two clinical programs performed in Europe and Japan, including dose-ranging, placebo-controlled, active comparator-controlled, and long-term (up to 65 weeks) studies. These studies demonstrated that dienogest 2 mg daily effectively alleviates the painful symptoms of endometriosis, reduces endometriotic lesions, and improves indices of quality of life. Dienogest showed a favorable safety and tolerability profile in these studies, with predictable adverse effects, high rates of patient compliance, and low withdrawal rates. This review article describes the clinical trial evidence that characterizes the efficacy and safety of dienogest in endometriosis, including two studies characterizing dienogest in long-term use. The relevance of these findings to the management of endometriosis in clinical practice is discussed.
