RESUMO

WHAT IS THIS SUMMARY ABOUT?: This is a summary of findings from two research studies (known as clinical trials). The studies looked at how well a medicine called relugolix combination therapy worked in women with heavy menstrual bleeding (heavy bleeding during a period) with uterine fibroids (noncancerous or benign growths in the uterus). In this analysis of the studies, researchers looked at how patients self-reported their uterine fibroid symptoms before and after taking relugolix combination therapy. Researchers also looked at how patients self-reported the impact of uterine fibroids on their health-related quality of life before and after taking relugolix combination therapy. WHAT WERE THE RESULTS?: Women took either relugolix combination therapy or placebo (a pill that contains no medicine) by mouth once daily for 24 weeks. Women completed the Uterine Fibroid Symptom and Quality of Life questionnaire (where "quality of life" refers to the women's health-related quality of life related to uterine fibroids) before, during, and after treatment. The questionnaire let researchers see if the women felt that relugolix combination therapy decreased the burden of uterine fibroid symptoms and improved the women's health-related quality of life related to uterine fibroids. More women said that they felt less distress due to their uterine fibroid symptoms and that their health-related quality of life related to uterine fibroids was better after taking relugolix combination therapy compared with women who took placebo. WHAT DO THE RESULTS MEAN?: Relugolix combination therapy may lessen distress associated with uterine fibroid symptoms and improve health-related quality of life related to uterine fibroids.

RESUMO

OBJECTIVES: To assess the effectiveness of a topical treatment for cervical ectropion with vaginal ovules containing aqueous extract of Triticum vulgare . METHODS: Prospective observational cohort study conducted between November 2020 and November 2022 at the colposcopy clinics of 2 different hospitals. Sexually active patients with a colposcopic diagnosis of cervical ectropion, awaiting ablative procedure, were included in the study and prescribed medical therapy with vaginal T. vulgare ovules (group 1) or wait-and-see therapy (group 2). At both enrollment and 2-month follow-up, a symptomatologic evaluation recording the intensity of postcoital bleeding, leucorrhea, and dyspareunia was performed with a Visual Analog Scale (VAS) questionnaire, and a colposcopic examination was performed, calculating the size of the ectropion area. RESULTS: A total of 116 patients (58 in group 1 and 58 in group 2) were included. Topical treatment with vaginal ovules containing aqueous extract of T. vulgare for 2 months resulted in significant decrease of symptoms related to cervical ectropion and significant reduction of the size of the ectropion area. CONCLUSIONS: Our results support the efficacy of topical treatment with vaginal ovules containing aqueous extract of T. vulgare for symptomatic cervical ectropion; our study also suggests that expectant management, despite being widely practiced, seems to lead to a worsening of the natural history of ectropion.

RESUMO

OBJECTIVE: To investigate the effects of 52 weeks of treatment with relugolix combination therapy (relugolix 40 mg, estradiol 1 mg, norethindrone acetate 0.5 mg) on symptoms of uterine fibroids (UF) and quality of life (QoL) in women with heavy menstrual bleeding associated with UF and anemia (hemoglobin ≤10.5 g/dL) at baseline. METHODS: This post hoc analysis included women from the LIBERTY long-term extension study with anemia (hemoglobin concentration ≤10.5 g/dL) at pivotal study baseline and documented hemoglobin values at week 52 (anemia-evaluable population). Treatment responders: women achieving a menstrual blood loss volume of <80 mL and a ≥50% reduction over the last 35 days of treatment. Anemia responders were women achieving a hemoglobin increase of >2 g/dL from baseline to week 52. Least squares (LS) mean changes from baseline in uterine fibroid symptom (UFS)-QoL symptom severity, fatigue, and health-related QoL total (HR-QoL) and (sub)scale scores were calculated. RESULTS: In total, 115 women were included in the anemia-evaluable population. Of 39 anemia-evaluable women who received continuous treatment with relugolix combination therapy for 52 weeks, 34 (87.2%) met treatment responder criteria and 23 (59.0%) were anemia responders. LS mean hemoglobin concentration increased by 29.4% at week 52. LS mean UFS-QoL symptom severity and fatigue scores decreased by 38.5 and 31.9 points, respectively, and HR-QoL total score increased by 41.6 points. CONCLUSION: In women with UF and a high disease burden due to anemia, relugolix combination therapy substantially improved hemoglobin levels, decreased distress due to symptoms, especially fatigue, over 52 weeks.

RESUMO

OBJECTIVE: To outline oocyte competence after progestin primed ovarian stimulation with Norethisterone acetate (NETA-PPOS) compared to conventional GnRH-antagonist protocol. STUDY DESIGN: Retrospective matched case-control study involving advanced-maternal-age women undergoing ICSI with PGT-A. 89 NETA-PPOS were matched with 178 control patients based on maternal age and ovarian reserve biomarkers. Both groups underwent recombinant-FSH OS with GnRH-agonist ovulation trigger and collected ≥1 MII. In the study group, NETA (10 mg/day) was administered orally starting from day2 of the menstrual cycle. Euploid blastocyst rate per cohort of metaphase-II oocytes (EBR per MII) was the primary outcome. All other embryological and clinical outcomes were reported. Gestational age, birthweight and length were also assessed. RESULTS: The EBR per MII was comparable among PPOS and control (13.9 % ± 19.3 % versus 13.3 % ± 17.9 %; the sample size allowed to exclude up to a 10 % difference). Blastocysts morphology and developmental rate were similar. No difference was reported for all clinical outcomes among the 61 and 107 vitrified-warmed euploid single blastocyst transfers respectively conducted. The cumulative live birth delivery rate per concluded cycles was also comparable (24.7 % versus 21.9 %). Neonatal outcomes were analogous. CONCLUSIONS: Oocyte competence after NETA-PPOS and standard OS is comparable. This evidence is reassuring and, because of its lower cost and possibly higher patients' compliance, supports PPOS administration whenever the patients are indicated to freeze-all (e.g., fertility preservation, PGT-A, oocyte donation). More data are required about follicle recruitment, oocyte yield, gestational and perinatal outcomes. Randomized-controlled-trials are advisable to confirm our evidence.

RESUMO

BACKGROUND: In the pivotal LIBERTY 1 and 2 trials and long-term extension study, once-daily relugolix combination therapy (40 mg relugolix, 1 mg estradiol, 0.5 mg norethindrone acetate) reduced menstrual blood loss volume and pain among women with uterine fibroids. Relugolix combination therapy was well tolerated with preservation of bone mineral density through 52 weeks. OBJECTIVE: This study aimed to report the 2-year relugolix combination therapy efficacy and safety results of the phase 3 LIBERTY randomized withdrawal study. STUDY DESIGN: Women with uterine fibroid-associated heavy menstrual bleeding who completed the 24-week LIBERTY 1 or 2 trials, followed by the 28-week long-term extension study (up to 52 weeks total treatment), and who met the responder criteria (menstrual blood loss volume <80 mL and ≥50% reduction from pivotal study baseline at week 48 [week 24 of long-term extension]) were randomized in a 1:1 ratio to either blinded treatment with relugolix combination therapy or placebo for 52 weeks (total treatment period, 104 weeks). For women who had a relapse of heavy menstrual bleeding during the study (menstrual blood loss volume ≥80 mL), open-label relugolix combination therapy was offered. The primary endpoint was the proportion of women who maintained menstrual blood loss volume <80 mL through week 76 (week 24 of randomized withdrawal study). Secondary endpoints included time to menstrual blood loss volume ≥80 mL, proportion of women who maintained a menstrual blood loss volume of <80 mL through week 104 (over the 52-week randomized treatment period), the proportion of women who achieved or maintained amenorrhea at week 76 at the end of treatment, and the change in Uterine Fibroid Symptom-Quality of Life Bleeding and Pelvic Discomfort Scale and symptom severity scores. Analyses were performed for the modified intent-to-treat population, including all randomized women who received ≥1 dose of the study drug. RESULTS: Of the 229 randomized women (relugolix combination therapy, n=115; placebo, n=114), 228 received the study drug and 175 (76.7%) completed the randomized withdrawal study. Through week 76, 78.4% of women on relugolix combination therapy maintained menstrual blood loss volume <80 mL vs 15.1% in the placebo group (difference, 63.4%; 95% confidence interval, 52.9%-73.9%; P<.0001). At week 104, 69.8% of women on relugolix combination therapy maintained menstrual blood loss volume <80 mL vs 11.8% in the placebo group (difference, 58.0%; 95% confidence interval, 47.0%-69.1%; P<.0001). Through week 104, 88.3% of women on placebo relapsed with heavy menstrual bleeding (median time to relapse, 5.9 weeks). Among the 89 women in the placebo group who relapsed and received open-label rescue treatment, 87 women responded to relugolix combination therapy with a menstrual blood loss volume <80 mL. The proportion of women who achieved or maintained amenorrhea were 57.4% vs 13.3% at week 76 (difference, 44.1%; 95% confidence interval, 33.10%-55.1%; P<.0001) and 58.3% vs 10.6% at week 104 (difference, 47.6%; 95% confidence interval, 37.0%-58.3%; nominal P<.0001) for relugolix combination therapy and the placebo group, respectively. Relugolix combination therapy was generally well tolerated; no new safety signals were identified, and the adverse event profile over the second year was consistent with that reported through the first year of treatment. Bone mineral density remained stable in women who received relugolix combination therapy from week 52 to week 104. In women continuously treated with relugolix combination therapy up to 2 years, bone mineral density was generally preserved. CONCLUSION: After 2 years of treatment with relugolix combination therapy, there was evidence of durability of the effect in maintaining low menstrual blood loss volume in women with symptomatic uterine fibroids. Most women had return of heavy menstrual bleeding and associated symptoms after treatment cessation, which improved upon retreatment with relugolix combination therapy. Relugolix combination therapy was well tolerated, the adverse event profile remained consistent, and the mean bone mineral density was generally preserved through 2 years of treatment.

RESUMO

OBJECTIVE: In the 24-week, phase 3 LIBERTY 1 (L1) and LIBERTY 2 (L2) trials, relugolix combination therapy (relugolix-CT (relugolix 40 mg, estradiol 1 mg, norethisterone acetate 0.5 mg)) reduced uterine fibroid (UF)-associated symptoms. This post hoc analysis assessed safety and efficacy of relugolix-CT in European women from L1/L2. METHODS: Premenopausal women (aged 18-50 years) with UF-associated heavy menstrual bleeding (HMB) were randomized 1:1:1 in L1 (N = 388) and L2 (N = 382) to relugolix-CT or placebo for 24 weeks, or delayed relugolix-CT (relugolix 40 mg then relugolix-CT; 12 weeks each). Primary endpoint: proportion of responders (menstrual blood loss (MBL) <80 mL and reduction of ≥50% from baseline MBL volume) over the last 35 days of treatment. Secondary endpoints: MBL volume, amenorrhea, UF-associated pain, symptom severity, distress related to bleeding and pelvic discomfort, health-related quality of life (HRQoL). Safety endpoints included adverse event (AE) reporting and bone mineral density (BMD) assessment. RESULTS: In European women from L1/L2 (N = 124, 16%), a significantly greater proportion of treatment responders was observed with relugolix-CT vs. placebo (85.4% vs. 19.1%, respectively; nominal p < .0001). There were statistically significant improvements with relugolix-CT vs. placebo for several secondary endpoints: reduction in MBL volume, amenorrhea rate, proportion achieving mild-to-no pain, reduction in symptom severity and distress from bleeding and pelvic discomfort, and improvement in HRQoL. Incidence of AEs and percentage changes in BMD from baseline to week 24 were similar for relugolix-CT and placebo. CONCLUSIONS: In European women with UF and HMB, once-daily relugolix-CT vs. placebo improved UF-associated symptoms and preserved BMD.

RESUMO

What is this summary about? This is a summary of a research study (known as a clinical trial) called the LIBERTY extension study. The LIBERTY extension study is a long-term study looking at how well a medicine called relugolix combination therapy worked in reducing blood loss during menstrual periods in women with uterine fibroids with heavy menstrual periods. Women were included in the extension study if they finished the 24-week LIBERTY 1 or LIBERTY 2 studies. Heavy menstrual periods were considered to be menstrual blood loss of about one-third of a cup of blood (80 ml) per cycle for two cycles or about two-thirds of a cup of blood (160 ml) during one cycle. The LIBERTY extension study also looked at whether relugolix combination therapy was safe to take for up to 1 year. What were the results? Out of 770 total women with uterine fibroids with heavy menstrual bleeding who took part in the LIBERTY 1 and LIBERTY 2 studies, 476 took part in the LIBERTY extension study. From the start of the LIBERTY 1 and LIBERTY 2 studies through the end of the LIBERTY extension: 163 women took relugolix combination therapy for 52 weeks 149 women took relugolix alone for 12 weeks followed by relugolix combination therapy for 40 weeks 164 women took placebo for 24 weeks followed by relugolix combination therapy for 28 weeks The LIBERTY extension study showed that most women in all three treatment groups responded to relugolix combination therapy by having less bleeding during their menstrual periods, having improved anemia symptoms, and having stable bone mineral loss. Side effects were similar across treatment groups, and the most common side effects were headaches and hot flushes. What do the results mean? Women with uterine fibroids with heavy menstrual bleeding taking relugolix combination therapy may have fewer uterine fibroid bleeding symptoms for up to 1 year of treatment. Clinical Trial Registration: NCT03049735 (ClinicalTrials.gov) (LIBERTY 1) Clinical Trial Registration: NCT03103087 (ClinicalTrials.gov) (LIBERTY 2) Clinical Trial Registration: NCT03412890 (ClinicalTrials.gov) (LIBERTY extension study).

RESUMO

WHAT IS THIS SUMMARY ABOUT?: This is a summary of research studies (known as clinical trials) called LIBERTY 1 and LIBERTY 2. The LIBERTY 1 and LIBERTY 2 studies looked at how well a medication called relugolix combination therapy worked to reduce heavy bleeding at the time of menstruation compared with placebo. The studies also looked at what side effects were reported in women with uterine fibroids and heavy menstrual bleeding. WHAT WERE THE RESULTS?: Researchers looked at 388 adult women in the LIBERTY 1 study and 382 adult women in the LIBERTY 2 study. All women had heavy menstrual bleeding with uterine fibroids before the start of the LIBERTY 1 and LIBERTY 2 studies. The women were given one of three treatments during the studies: relugolix combination therapy or placebo for 24 weeks, or delayed relugolix combination therapy (relugolix alone for the first 12 weeks, then relugolix combination therapy for the last 12 weeks of the studies). More women taking relugolix combination therapy in the LIBERTY 1 study (73%) and LIBERTY 2 study (71%) had menstrual blood loss of less than one-third of a cup (80 mL) and had reduction of at least 50% less blood loss during their last menstrual period after 24 weeks of taking the medicine compared with placebo (LIBERTY 1: 19% and LIBERTY 2: 15%). The women taking relugolix combination therapy also had less pain than those taking placebo. Side effects were similar across treatment groups. Headaches and hot flushes were the most common side effects. WHAT DO THE RESULTS MEAN?: More women with uterine fibroids taking relugolix combination therapy for 24 weeks were likely to have fewer uterine fibroid symptoms than women receiving placebo. Clinical Trial Registration: NCT03049735 (LIBERTY 1); NCT03103087 (LIBERTY 2).

RESUMO

This is the first contribution of a series of interventions describing the EASY-NET research program (Bando Ricerca Finalizzata 2016, funds 2014-2015; NET-2016-02364191). Here, the objective is to illustrate the background and the research question, the structure and organization, the methodologies and the expected results of the programme. The main theme is audit&feedback (A&F), a proven and widespread technique for improving the quality of health care. EASY-NET, funded by the Italian Ministry of Health and by the governments of the participating Italian Regions, starts its research activities in 2019 with the aim of evaluating the effectiveness of A&F in improving care for different clinical conditions in various organizational and legislative contexts. The research network involves seven Italian Regions, each conducting specific research activities described by as many work packages (WP): Lazio (the leading Region, coordinator of the research activities), Friuli Venezia Giulia, Piedmont, Lombardy, Emilia-Romagna, Calabria, and Sicily. The involved clinical areas include the management of chronic diseases, emergency care for acute conditions, surgery in the oncological area, the treatment of heart disease, obstetrics, and the use of caesarean section and post-acute rehabilitation. The involved settings concern the community, the hospital, the emergency room, and the rehabilitation facilities. Different experimental or quasi-experimental study designs are applied in each WP to achieve specific objectives of the specific clinical and organizational context. In all WPs, the process and outcome indicators are calculated on the basis of the Health Information Systems (HIS) and, in some cases, they are integrated with measures obtained from ad hoc data collections. The programme aims to contribute to the scientific evidence on A&F also exploring the obstacles and favourable factors for its effectiveness and to promote its implementation in the health service, with the ultimate aim of improving the access to healthcare and the health outcomes for citizens.

RESUMO

BACKGROUND: Symptomatic uterine fibroids are burdensome to live with; they are associated with symptom-related distress, affect daily activities, and reduce health-related quality of life. The LIBERTY randomized clinical trials showed that oral relugolix combination therapy (40 mg relugolix, 1 mg estradiol, and 0.5 mg norethindrone acetate once daily) markedly improved fibroid-associated symptoms and conditions, including heavy menstrual bleeding, pain, and anemia, and was well-tolerated. OBJECTIVE: This study aimed to evaluate the effect of relugolix combination therapy on the symptom burden and health-related quality of life among women with uterine fibroids. STUDY DESIGN: Two replicate, multinational, double-blind, 24-week, randomized, placebo-controlled, phase 3 studies, LIBERTY 1 and LIBERTY 2, were conducted in premenopausal women with uterine fibroid-associated heavy menstrual bleeding (≥80 mL per cycle for 2 cycles or ≥160 mL during 1 cycle). The symptom burden and health-related quality of life were secondary endpoints and were assessed using the validated Uterine Fibroid Symptom and Quality of Life questionnaire, which the participants completed at baseline and at week 12 and 24 of treatment. For this secondary analysis, the pooled LIBERTY 1 and LIBERTY 2 data set was used. The Uterine Fibroid Symptom and Quality of Life questionnaire is made up of a Symptom Severity scale and a Health-Related Quality of Life scale, the latter of which includes 6 subscales focusing on the following aspects of daily life: concern, activities, energy or mood, control, self-consciousness, and sexual function. The Revised Activities subscale of the Health-Related Quality of Life scale addresses the impact of uterine fibroids on physical and social activities. Symptom burden was also assessed via the Bleeding and Pelvic Discomfort subscale, a patient-reported outcome measure derived from the Uterine Fibroid Symptom Severity scale that focuses on distress from key uterine fibroid symptoms, which was a key secondary endpoint. Least squares mean changes from baseline to week 24 in the Symptom Severity scale, Bleeding and Pelvic Discomfort subscale, overall Health-Related Quality of Life scale, and the respective subscales were compared between the relugolix combination therapy and placebo groups. Responder analyses of the proportion of women who experienced a clinically meaningful change from baseline to week 24 were conducted for the Bleeding and Pelvic Discomfort and the activity subscales. A stratified Cochran-Mantel-Haenszel test, adjusted for stratification factors (region [North America vs rest of world] and baseline menstrual blood loss volume), was used for treatment comparisons. RESULTS: Across both trials, 509 women were randomized to the relugolix combination therapy or placebo groups (April 2017-December 2018). Participants on relugolix combination therapy showed a statistically significant reduction in symptom severity (-33.5 vs -12.1; nominal P<.0001) and the Bleeding and Pelvic Discomfort subscale from baseline to week 24 when compared with those on placebo treatment (-48.4 vs -17.4; nominal P<.0001). Overall, the total Health-Related Quality of Life scores improved significantly from baseline to week 24 in the relugolix combination therapy group when compared with the placebo (+37.6 vs +13.1; nominal P<.0001). Responder analyses demonstrated that more women treated with relugolix combination therapy reported a clinically meaningful reduction in the Bleeding and Pelvic Discomfort subscale and an improvement in physical and social activities when compared with those treated with the placebo (nominal P<.0001). CONCLUSION: After 24 weeks of treatment with relugolix combination therapy, women with symptomatic uterine fibroids experienced substantial improvements in health-related quality of life with all subscales showing improvement, including emotional well-being, physical and social activities, and sexual function. In addition, women reported substantial reductions in the overall symptom burden and distress caused by key fibroid-associated symptoms.

RESUMO

OBJECTIVE: In the LIBERTY 1 and LIBERTY 2 placebo-controlled trials, once-daily relugolix combination therapy reduced menstrual blood loss volume and pain in women with heavy menstrual bleeding associated with uterine leiomyomas and was well tolerated, with preservation of bone mineral density (BMD) through 24 weeks. Here we report the long-term efficacy and safety of relugolix combination therapy treatment for up to 52 weeks. METHODS: Women with uterine leiomyoma-associated heavy menstrual bleeding who completed any treatment arm in either the LIBERTY 1 or LIBERTY 2 trial were eligible to enroll in a 28-week long-term extension study. All participants received once-daily relugolix combination therapy (40 mg relugolix, estradiol 1 mg, norethindrone acetate 0.5 mg) in the extension study. The primary efficacy endpoint was the proportion of women who achieved or maintained a menstrual blood loss volume of less than 80 mL and a 50% or greater reduction in menstrual blood loss volume from LIBERTY study baseline to the last 35 days of treatment (defined as responders ). Analyses were conducted for all three randomized treatment groups from pivotal studies. RESULTS: Overall, 477 women enrolled, 476 were treated, and 363 (76.1%) completed 52 weeks. Among patients treated with relugolix combination therapy through 52 weeks (n=163), sustained improvement in heavy menstrual bleeding was observed in 87.7% (responders). The least squares mean menstrual blood loss volume reduction was 89.9%, with 70.6% of patients achieving amenorrhea. At week 52, 59.0% of patients with anemia at baseline had improvements in hemoglobin concentration of greater than 2 g/dL. Distress due to uterine leiomyoma-associated symptoms measured by the BPD (Bleeding and Pelvic Discomfort) scale score was reduced by 51.3 points. Sustained reductions in uterine and uterine leiomyoma volume were observed. Bone mineral density was preserved through week 52. CONCLUSION: Improvements in heavy menstrual bleeding and anemia and reduction of uterine leiomyoma-associated symptom burden were sustained through up to 52 weeks of treatment with relugolix combination therapy in women with uterine leiomyomas. No new safety concerns were identified, and BMD was maintained. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov , NCT03049735; NCT03103087; NCT03412890. FUNDING SOURCE: Myovant Sciences GmbH.

RESUMO

OBJECTIVE: To assess the effect of once-daily relugolix combination therapy (relugolix-CT: relugolix 40 mg, estradiol 1 mg, and norethindrone acetate 0.5 mg) compared with placebo on moderate-to-severe pain in women with uterine leiomyomas and heavy menstrual bleeding. METHODS: Two replicate, multinational, double-blind, 24-week, randomized, phase 3 studies (LIBERTY 1 and 2) were conducted in premenopausal women with uterine leiomyoma-associated heavy menstrual bleeding (80 mL or greater per cycle for two cycles or 160 mL or greater during one cycle). A predefined secondary objective was to determine the effect of relugolix-CT on moderate-to-severe uterine leiomyoma-associated pain in the pain subpopulation (women with maximum pain scores of 4 or higher on the 0-10 numerical rating scale at baseline, with pain score reporting compliance of 80% (ie, 28 days or more over the last 35 days of treatment). This key secondary endpoint was defined as the proportion of women achieving minimal-to-no uterine leiomyoma-associated pain (maximum numerical rating scale score 1 or lower) at week 24; menstrual and nonmenstrual pain were evaluated in prespecified secondary analyses. Treatment comparisons were performed in the pooled LIBERTY 1 and 2 pain subpopulation using the Cochran-Mantel-Haenszel test stratified by baseline menstrual blood loss volume. RESULTS: Across both trials, 509 women were randomized to relugolix-CT or placebo (April 2017-December 2018). Of these, 277 (54.4%) met pain subpopulation requirements. With relugolix-CT, 45.2% (95% CI 36.4-54.3) of women achieved minimal-to-no pain compared with 13.9% (95% CI 8.8-20.5) with placebo (nominal P<.001). The proportions of women with minimal-to-no pain during menstrual days and during nonmenstrual days were significantly higher with relugolix-CT (65.0% [95% CI 55.6-73.5] and 44.6% [95% CI 32.3-57.5], respectively) compared with placebo (19.3% [95% CI 13.2-26.7], nominal P<.001, and 21.6% [95% CI 12.9-32.7], nominal P=.004, respectively). CONCLUSION: Over 24 weeks, relugolix-CT significantly reduced moderate-to-severe uterine leiomyoma-associated pain with a more pronounced effect on menstrual pain. These data support that relugolix-CT had clinically meaningful effects on women's experience of uterine leiomyoma-associated pain.

RESUMO

OBJECTIVE: Primary non-Hodgkin's lymphomas of the cervix are rare; they represent about 1% of all cases. There are no available guidelines regarding the safest mode of delivery after treatment and resolution of a cervical lymphoma. Case Report. We report the first case of a successful vaginal delivery after induction of labour in a woman recovered from a primary large B-cell lymphoma of the cervix and a literature review. CONCLUSION: In carefully selected patients with fully treated non-Hodgkin's lymphoma of the cervix with no residual disease, induction of labour via prostaglandins pessary may be a safe option if indicated.

RESUMO

Pancreatic cancer is rarely diagnosed during pregnancy; it usually manifests with symptoms such as epigastric pain, vomiting, weight loss, and jaundice, rarely mimicking the hemolysis, elevated liver enzymes, and low platelet count syndrome. It has been postulated that there exists a correlation between the diagnosis of gestational diabetes mellitus and the occurrence of pancreatic cancer later in life. We conducted an expert literature review of the 31 available documented pancreatic cancer cases that were diagnosed during pregnancy. We also report pancreatic adenocarcinoma incidentally suspected in an asymptomatic woman affected by gestational diabetes mellitus; the woman was undergoing a fetal growth scan.

RESUMO

BACKGROUND: Uterine fibroids are a common cause of heavy menstrual bleeding and pain. Treatment with the combination of relugolix (an oral gonadotropin-releasing hormone-receptor antagonist), estradiol, and norethindrone acetate, administered once daily, may have efficacy in women with uterine fibroids and heavy bleeding while avoiding hypoestrogenic effects. METHODS: We conducted two replicate international, double-blind, 24-week, phase 3 trials involving women with fibroid-associated heavy menstrual bleeding. Participants were randomly assigned in a 1:1:1 ratio to receive once-daily placebo, relugolix combination therapy (40 mg of relugolix, 1 mg of estradiol, and 0.5 mg of norethindrone acetate), or delayed relugolix combination therapy (40 mg of relugolix monotherapy, followed by relugolix combination therapy, each for 12 weeks). The primary efficacy end point in each trial was the percentage of participants with a response (volume of menstrual blood loss <80 ml and a ≥50% reduction in volume from baseline) in the relugolix combination therapy group, as compared with the placebo group. Key secondary end points were amenorrhea, volume of menstrual blood loss, distress from bleeding and pelvic discomfort, anemia, pain, fibroid volume, and uterine volume. Safety and bone mineral density were assessed. RESULTS: A total of 388 women in trial L1 and 382 in trial L2 underwent randomization. A total of 73% of the participants in the relugolix combination therapy group in trial L1 and 71% of those in trial L2 had a response (primary end point), as compared with 19% and 15%, respectively, of those in the placebo groups (P<0.001 for both comparisons). Both relugolix combination therapy groups had significant improvements, as compared with the placebo groups, in six of seven key secondary end points, including measures of menstrual blood loss (including amenorrhea), pain, distress from bleeding and pelvic discomfort, anemia, and uterine volume, but not fibroid volume. The incidence of adverse events was similar with relugolix combination therapy and placebo. Bone mineral density was similar with relugolix combination therapy and placebo but decreased with relugolix monotherapy. CONCLUSIONS: Once-daily relugolix combination therapy resulted in a significant reduction in menstrual bleeding, as compared with placebo, and preserved bone mineral density in women with uterine fibroids.

RESUMO

Copy Number Alterations (CNAs) represent the most common genetic alterations identified in ovarian cancer cells, being responsible for the extensive genomic instability observed in this cancer. Here we report the identification of CNAs in a cohort of Italian patients affected by ovarian cancer performed by SNP-based array. Our analysis allowed the identification of 201 significantly altered chromosomal bands (70 copy number gains; 131 copy number losses). The 3300 genes subjected to CNA identified here were compared to those present in the TCGA dataset. The analysis allowed the identification of 11 genes with increased CN and mRNA expression (PDCD10, EBAG9, NUDCD1, ENY2, CSNK2A1, TBC1D20, ZCCHC3, STARD3, C19orf12, POP4, UQCRFS1). PDCD10 was selected for further studies because of the highest frequency of CNA. PDCD10 was found, by immunostaining of three different Tissue Micro Arrays, to be over-expressed in the majority of ovarian primary cancer samples and in metastatic lesions. Moreover, significant correlations were found in specific subsets of patients, between increased PDCD10 expression and grade (p < 0.005), nodal involvement (p < 0.05) or advanced FIGO stage (p < 0.01). Finally, manipulation of PDCD10 expression by shRNA in ovarian cancer cells (OVCAR-5 and OVCA429) demonstrated a positive role for PDCD10 in the control of cell growth and motility in vitro and tumorigenicity in vivo. In conclusion, this study allowed the identification of novel genes subjected to copy number alterations in ovarian cancer. In particular, the results reported here point to a prominent role of PDCD10 as a bona fide oncogene.

RESUMO

OBJECTIVE: To evaluate the true impact of endometriosis on oocytes' competence defined as blastulation, euploidy and implantation rates. DESIGN: Retrospective multicenter case-control study involving infertile couples undergoing ICSI with qPCR and trophectoderm biopsy-based PGT-A. Patients affected from endometriosis (n = 210) were diagnosed through transvaginal sonography or surgical history with histological confirmation. Each case was matched to two controls (n = 420) according to IVF clinic, maternal age at retrieval (38.6 ± 2.7 yr), number of previous failed IVF treatments (0.5 ± 0.8) and number of metaphase-II oocytes retrieved (6.1 ± 3.7 per patient). The primary outcome was the mean euploid blastocyst rate per cohort of inseminated metaphase-II oocytes. Other embryological, clinical, obstetric and neonatal outcomes were also evaluated. RESULTS: The mean euploid blastocyst rate per cohort of inseminated metaphase-II oocytes was identical in the two groups (18 %±22 %) independently of maternal age. No difference was shown for all embryological outcomes investigated. The live birth rates per vitrified-warmed single euploid blastocyst transfer were also similar (67/158, 42 % in patients affected from endometriosis versus 132/327, 40 % in matched-controls). No difference was reported in the gestational and neonatal outcomes. The cumulative live birth delivery rates among completed cycles were also identical (61/201, 30 % versus 117/391, 30 % in endometriosis and matched-control groups, respectively) independently of maternal age. CONCLUSIONS: Endometriosis might not impair oocyte developmental and reproductive competence, although its potential impact on the number of metaphase-II oocytes retrieved cannot be ignored. This information is critical for clinicians during counseling to outline an effective strategy to treat infertile patients affected from this condition. Future prospective studies are needed to evaluate the impact of endometriosis stage on euploidy rates.

RESUMO

BACKGROUND: Uterine leiomyomas, also referred to as myomas or fibroids, are benign tumours arising from the smooth muscle cells of the myometrium. They are the most common pelvic tumour in women. The estimated rate of leiomyosarcoma, found during surgery for presumed benign leiomyomas, is about 0.51 per 1000 procedures, or approximately 1 in 2000. Treatment options for symptomatic uterine leiomyomas include medical, surgical, and radiologically-guided interventions. Laparoscopic myomectomy is the gold standard surgical approach for women who want offspring, or otherwise wish to retain their uterus. A limitation of laparoscopy is the inability to remove large specimens from the abdominal cavity through the laparoscope. To overcome this challenge, the morcellation approach was developed, during which larger specimens are broken into smaller pieces in order to remove them from the abdominal cavity via the port site. However, intracorporeal power morcellation may lead to scattering of benign tissues, with the risk of spreading leiomyoma or endometriosis. In cases of unsuspected malignancy, power morcellation can cause unintentional dissemination of malignant cells, and lead to a poorer prognosis by upstaging the occult cancer. A strategy to optimise women's safety is to morcellate the specimens inside a bag. In-bag morcellation may avoid the dissemination of tissue fragments. OBJECTIVES: To evaluate the effectiveness and safety of protected in-bag extracorporeal manual morcellation during laparoscopic myomectomy compared to intra-abdominal uncontained power morcellation. SEARCH METHODS: On 1 July 2019, we searched; the Cochrane Gynaecology and Fertility Group Specialized Register of Controlled Trials, CENTRAL, MEDLINE, Embase, PsycINFO, CINAHL, LILACS, PubMed, Google Scholar, and two trials registers. We reviewed the reference lists of all retrieved full-text articles, and contacted experts in the field for additional and ongoing trials. SELECTION CRITERIA: We included all randomised controlled trials comparing in-bag extracorporeal manual morcellation versus intracorporeal uncontained power morcellation during laparoscopic myomectomy in premenopausal women. DATA COLLECTION AND ANALYSIS: We followed standard Cochrane methods. Two review authors independently reviewed the eligibility of trials, extracted data, and evaluated the risk of bias. Data were checked for accuracy. The summary measures were reported as risk ratios (RR) or mean differences (MD) with 95% confidence interval (CI). The outcomes of interest were a composite of intraoperative and postoperative complications, operative times, ease of morcellation, length of hospital stay, postoperative pain, conversion to laparotomy, and postoperative diagnosis of leiomyosarcoma. Results for the five main outcomes follow. MAIN RESULTS: We included two trials, enrolling 176 premenopausal women with fibroids, who underwent laparoscopic myomectomy. The experimental group received in-bag manual morcellation, during which each enucleated myoma was placed into a specimen retrieval bag, and manually morcellated with scalpel or scissors. In the control group, intracorporeal uncontained power morcellation was used to reduce the size of the myomas. No intraoperative complications, including accidental morcellation of the liver, conversion to laparotomy, endoscopic bag disruption, bowel injury, bleeding, accidental injury to any viscus or vessel, were reported in either group in either trial. We found very low-quality evidence of inconclusive results for total operative time (MD 9.93 minutes, 95% CI -1.35 to 21.20; 2 studies, 176 participants; I² = 35%), and ease of morcellation (MD -0.73 points, 95% CI -1.64 to 0.18; 1 study, 104 participants). The morcellation operative time was a little longer for the in-bag manual morcellation group, however the quality of the evidence was very low (MD 2.59 minutes, 95% CI 0.45 to 4.72; 2 studies, 176 participants; I² = 0%). There were no postoperative diagnoses of leiomyosarcoma made in either group in either trial. We are very uncertain of any of these results. We downgraded the quality of the evidence due to indirectness and imprecision, because of limited sites in high-income settings and countries, small sample sizes, wide confidence intervals, and few events. AUTHORS' CONCLUSIONS: There are limited data on the effectiveness and safety of in-bag morcellation at the time of laparoscopic myomectomy compared to uncontained power morcellation. We were unable to determine the effects of in-bag morcellation on intraoperative complications as no events were reported in either group. We are uncertain if in-bag morcellation improves total operative time or ease of morcellation compared to control. Regarding morcellation operative time, the quality of the evidence was also very low and we cannot be certain of the effect of in-bag morcellation compared to uncontained morcellation. No cases of postoperative diagnosis of leiomyosarcoma occurred in either group. We found only two trials comparing in-bag extracorporeal manual morcellation to intracorporeal uncontained power morcellation at the time of laparoscopic myomectomy. Both trials had morcellation operative time as primary outcome and were not powered for uncommon outcomes such as intraoperative complications, and postoperative diagnosis of leiomyosarcoma. Large, well-planned and executed trials are needed.

RESUMO

BACKGROUND: Caesarean section (CS) is usually perceived as a simple and safe alternative to natural birth, but in some instances can be technically difficult with consequent health hazards for both the mother and the fetus. We have proposed an evidence-based literature review of the most common difficult CS scenarios, with the aim to provide useful information about their management, possible prevention and resolution of complications. METHODS: We identified articles through a reserch in PubMed, Scopus, Web of Science and Ovid MEDLINE for studies published between 1979 and 2019. We included the best available evidence, such as RCTs, non-randomised controlled clinical trials, case-control studies, cohort studies, and case series. About sixty articles were included in this review, four hundred and thirty-six were excluded after reviewing the title or abstract or because they weren't in English. FINDINGS: The possible causes of "difficult" caesarean sections were divided into four categories: difficult access to the lower uterine segment; complicated fetal extraction, laceration or organ damage and abnormal placentation. CONCLUSIONS: Knowing in advance the potential technical difficulties and resulting risks allows the surgeon to plan appropriate strategies.

RESUMO

Reactive oxygen species (ROS) mediates cisplatin-induced cytotoxicity in tumor cells. However, when cisplatin-induced ROS do not reach cytotoxic levels, cancer cells may develop chemoresistance. This phenomenon can be attributed to the inherited high expression of antioxidant protein network. H-Ferritin is an important member of the antioxidant system due to its ability to store iron in a nontoxic form. Altered expression of H-Ferritin has been described in ovarian cancers; however, its functional role in cisplatin-based chemoresistance of this cancer type has never been explored. Here, we investigated whether the modulation of H-Ferritin might affect cisplatin-induced cytotoxicity in ovarian cancer cells. First, we characterized OVCAR3 and OVCAR8 cells for their relative ROS and H-Ferritin baseline amounts. OVCAR3 exhibited lower ROS levels compared to OVCAR8 and greater expression of H-Ferritin. In addition, OVCAR3 showed pronounced growth potential and survival accompanied by the strong activation of pERK/pAKT and overexpression of c-Myc and cyclin E1. When exposed to different concentrations of cisplatin, OVCAR3 were less sensitive than OVCAR8. At the lowest concentration of cisplatin (6 µM), OVCAR8 underwent a consistent apoptosis along with a downregulation of H-Ferritin and a consistent increase of ROS levels; on the other hand, OVCAR3 cells were totally unresponsive, H-Ferritin was almost unaffected, and ROS amounts met a slight increase. Thus, we assessed whether the modulation of H-Ferritin levels was able to affect the cisplatin-mediated cytotoxicity in both the cell lines. H-Ferritin knockdown strengthened cisplatin-mediated ROS increase and significantly restored sensitivity to 6 µM cisplatin in resistant OVCAR3 cells. Conversely, forced overexpression of H-Ferritin significantly suppressed the cisplatin-mediated elevation of intracellular ROS subsequently leading to a reduced responsiveness in OVCAR8 cells. Overall, our findings suggest that H-Ferritin might be a key protein in cisplatin-based chemoresistance and that its inhibition may represent a potential approach for enhancing cisplatin sensitivity of resistant ovarian cancer cells.
