CA 125 elevado en contexto de endometrioma: reporte de caso / Elevated CA 125 in the context of endometrioma: case report

Introducción: Los tumores benignos de ovario corresponden a un 60-95% de las lesiones anexiales, en edad fértil los más frecuentes corresponden a quistes foliculares y endometriomas. Sin embargo, alrededor del 15% son patología maligna de ovario. Por lo que se debe evaluar aspectos como edad, características ecográficas y la presencia de marcadores tumorales específicos como CA 125. Objetivo general: Describir un reporte de caso y caracterizar la evidencia disponible sobre el abordaje de tumores benignos de ovario. Caso Clínico: Se presenta el caso clínico de una paciente en edad fértil de 43 años, cursando con dolor abdominal asociado a masa anexial, donde destaca la elevación del marcador CA 125 en rango de malignidad, por lo que se solicita valoración por oncología y manejo quirúrgico, confirmándose una masa anexial benigna de características quísticas, sugerente de endometrioma, al descartar patología maligna se realiza quistectomía total. Discusión: La patología anexial es una entidad clínica que puede abarcar características tumorales, ya sean benignas como malignas, por ello frente a lesiones ováricas, siempre se deben descartar estas últimas. Las características ecográficas de la paciente hacían sospechar de un endometrioma, el CA 125 elevado en ella hizo que se optara por un manejo quirúrgico oncológico con biopsia rápida para descartar o confirmar malignidad. Conclusión: Ante la presencia de endometriomas, el tratamiento debe discutirse caso a caso, teniendo en cuenta la sintomatología, deseos de fertilidad futura y tamaño de las lesiones.

Introduction: Benign ovarian tumors correspond to 60-95% of adnexal lesions, in childbearing years the most frequent correspond to follicular cysts and endometriomas. However, about 15% are malignant ovarian pathology. Therefore, aspects such as age, ultrasound characteristics and the presence of specific tumor markers such as CA 125 must be evaluated. General objective: Describe a case report and characterize the available evidence on benign ovarian tumors. Case report: A case of a 43 year old female of childbearing age, presents abdominal pain associated with an adnexal mass, where CA 125 elevations are found in the range of malignancy, for which an oncology evaluation and surgical management. A benign adnexal mass with cystic characteristics is confirmed, suggestive of endometrioma, when malignant pathology is ruled out, a total cystectomy is performed. Discussion: Adnexal pathology is a clinical entity that can include tumor characteristicas, whether benign or malignant, therefore, in the face of ovarian lesions, these should always be ruled out. The sonographic characteristics of the patient made one suspect an endometrioma, the elevated CA 125 in it led to an oncological surgical management with rapid biopsy to rule out or confirm malignancy. Conclusions: In the presence of endometriomas, treatmentshould be discussed individually, taking into account the symptoms, wishes for future fertility, and size of the lesions.

Gran mioma uterino: manejo prequirúrgico con uso de agonistas de gnrh: reporte de un caso / Large uterine myoma: presurgical management with the use of gnrh agonists: case report

Introducción: Los leiomiomas uterinos son los tumores pélvicos benignos más comunes entre las mujeres. Se estima que 60% de las mujeres llegan a tener miomatosis a lo largo de la vida (1). La necesidad de tratamiento médico y/o quirúrgico es muy importante de evaluar, ya que los fibromas son una fuente importante de morbilidad ginecológica. Objetivos: Describir el caso de un gran mioma uterino con manejo prequirúrgico de análogos de GnRH, analizando los hallazgos obtenidos en el caso según la evidencia actual. Discusión: Se reporta el caso de una mujer de 29 años sin antecedentes mórbidos conocidos, con presencia de una gran masa abdominal, motivo por el cual se realizó una ecotomografía abdominal que evidenció una masa sugerente de un gran mioma uterino subseroso. Se realizó miomectomía vía laparotomía previo tratamiento médico con análogos de GnRH. Actualmente la frecuencia de miomas de gran tamaño es poco frecuente, por lo que se busca discutir el impacto del tratamiento médico previo a la cirugía en mujeres jóvenes. Conclusiones: La experiencia con el uso prequirúrgico de agonistas de GnRH indica una ventaja en el trabajo bien definida y su uso como tratamiento coadyuvante a la cirugía está bien establecido. Sin embargo, se debe tener en cuenta la posibilidad de recurrencia de los miomas

Introduction: Uterine leiomyomas are the most common benign pelvic tumors in women. It is estimated that 60% of women develop myomatosis throughout life (1). The need for medical and / or surgical treatment is very important to assess, since fibroids are an important source of gynecological morbidity. Objectives: To describe the case of a large uterine myoma with presurgical management of GnRH analogues and to summarize updated evidence on their use. Discussion: The case of a 29-year-old woman with no known morbid history is reported, with the presence of a large abdominal mass, which is why an abdominal ultrasound scan was performed, which revealed a mass suggestive of a large subserous uterine myoma. Myomectomy was performed via laparotomy after medical treatment with GnRH analogues. Currently, the frequency of large fibroids is rare, so we seek to discuss the impact of medical treatment prior to surgery in young women. Conclusions: Experience with the presurgical use of GnRH agonists indicates a well-defined treatment advantage and its use as adjunctive treatment to surgery is well established. However, the possibility of recurrence of fibroids should be taken into account

Aberrant endometrial steroid receptor expression in in-vitro maturation cycles despite hormonal luteal support: A pilot study.

Clinical outcomes of fresh embryo transfer in non-hCG triggered in vitro maturation (IVM) cycles are inferior compared to vitrified-warmed embryo transfer. This is a prospective observational pilot study in a consecutive cohort of 31 polycystic ovary syndrome (PCOS) patients and 37 normo-ovulatory egg donors who underwent IVM without fresh embryo transfer between July 2009 and June 2014. All subjects received 150 IU of highly purified menotropin (HP-hMG) daily for three days. On cycle day 6, all patients started transdermal oestradiol (E2) at a daily dose of 9 mg. There was no human chorionic gonadotropin (hCG) trigger before oocyte retrieval (OR). Vaginal micronized progesterone was commenced on the evening after OR, at a daily dose of 600 mg. Additional luteal phase support (LPS) was administered as follows: Group A: no additional LPS; Group B: 1500 IU of hCG administered 4 h after OR and Group C: 5000 IU of hCG administered 4 h after OR + an additional injection of 5000 IU of hCG 1 day before endometrial biopsy. Endometrial biopsy for histology and immunohistochemistry (IHC) was performed on day 5 or 6 after OR. Instead of being downregulated, both PR-B and ERα in endometrial glands and stroma were moderately to strongly expressed in all three protocols, suggesting that the mid-luteal histological signature of endometrial receptivity is deficient in a non-hCG-triggered IVM cycle. Poor clinical outcomes after fresh embryo transfer following IVM are probably related to inappropriate endometrial development which may be linked to the short follicular phase of IVM cycles.

Does acupuncture the day of embryo transfer affect the clinical pregnancy rate? Systematic review and meta-analysis.

The effects of acupuncture on IVF outcomes is still unknown. We carried out a systematic review and meta-analysis of RCT to determine whether acupuncture performed at the time of ET improves outcomes. We searched Medline and Embase from January 1990 to June 2017, for the following terms): (acupuncture; acupuncture therapy) and (reproductive techniques, assisted; in vitro fertilization; embryo transfer). We selected RCT that compared acupuncture with sham acupuncture or no treatment. We included only trials in which acupuncture involved the insertion of needles into traditional meridian points. We evaluated the methodological quality of the trials using the Cochrane risk of bias tool. The measure of treatment effect was the pooled odds ratio of achieving a clinical pregnancy, ongoing pregnancy, or live birth for women in the acupuncture group compared with women in the control group. For pooled data, summary test statistics were calculated using the Mantel-Haenszel method, using the Rev-Man software, version 5.1. We analyzed six studies, including 2,376. In all trials, there were no significant differences between the groups concerning the mean numbers of embryos transferred, the mean age of the women undergoing the procedure, diagnose and use of ICSI. Acupuncture performed the day of ET was associated with a reduced risk of clinical pregnancy (0.87, 95% confidence interval 0.77 to 0.98). The pooled rate difference was -0.06 (-0.12 to -0.01) for clinical pregnancy. None of the trials reported significant adverse effects of acupuncture.

DHEA use to improve likelihood of IVF/ICSI success in patients with diminished ovarian reserve: A systematic review and meta-analysis.

The aim of this review is to determine if the use of DHEA increases the likelihood of success in patients with POR. We searched MEDLINE and EMBASE using the terms "DHEA and diminished ovarian reserve", "DHEA and poor response", "DHEA and premature ovarian aging". A fixed effects model was used and Peto's method to get the odds ratio (OR) with 95% confidence intervals (CI 95%). For quantitative variables, Cohen's method was used to present the standardized mean differences (SMD) with their corresponding confidence intervals. Only five studied fulfilled the selection criteria. DHEA was administered in 25 mg doses, three times a day. In all studies, the authors corrected for the presence of confounding variables such as partner's age, infertility diagnosis and number of transferred embryos. The meta-analysis of the five selected studies assessed a total of 910 patients, who underwent IVF/ICSI, of which 413 had received DHEA. DHEA use was associated with a significant increase in pregnancy likelihood (OR 1.8, CI 95% 1.29 to 2.51, p=0.001). When analyzing the association between DHEA use and the likelihood of abortion, we found low heterogeneity between studies (I2=0.0%) and the use of DHEA to be associated to a significant reduction in the likelihood of abortion (OR 0.25, CI 0.07 to 0.95; p=0.045). Analysis of the association of DHEA with average oocyte retrieval showed high variability between studies (I2=98.6%), as well as no association between DHEA use and the number of oocytes retrieved (SMD -0.01, CI 95% -0.16 to 0.13; p<0.05).

The effect of ovarian puncture on the endocrine profile of PCOS patients who undergo IVM.

BACKGROUND: To examine whether ovarian puncture for immature oocyte retrieval and in-vitro maturation (IVM) has an effect on the endocrine profile of patients with polycystic ovary syndrome (PCOS). METHODS: Twenty-two consecutive patients with PCOS undergoing IVM treatment were included. Serum anti-Müllerian hormone (AMH), sex hormone-binding globulin (SHBG), total testosterone (TT) and luteinized hormone (LH) levels were analyzed at the start of the cycle, on the day of immature oocyte retrieval (OR) and at fixed intervals thereafter, for up to three months after OR. RESULTS: Five days after OR circulating AMH, TT, calculated free testosterone (FTc), and LH levels were significantly reduced and circulating SHBG was significantly increased. Two weeks after OR, TT, FTc and LH remained reduced, whereas circulating AMH and SHBG levels recovered to pre-puncture values. Three months after OR, all circulating hormone levels had recovered to baseline values. CONCLUSION: Ovarian puncture for the retrieval of immature oocytes and IVM in patients with PCOS has a significant impact on the ovarian endocrine profile, but this impact is brief and transient.

Maduración in vitro de ovocitos humanos: una opción para preservar la fertilidad de las mujeres: reporte del primer caso realizado en Chile / Oocyte in vitro maturation: alternative approach for fertility preservation: report the first case in Chile

La maduración in vitro (MIV) de ovocitos humanos es parte de las técnicas de fecundación in vitro, que consiste en la aspiración de ovocitos inmaduros. Es ofrecida principalmente a pacientes con alto riesgo de desarrollar un síndrome de hiperestimulación ovárica, especialmente pacientes con síndrome de ovario poliquístico. Adicionalmente, es un método ofrecido a las pacientes oncológicas para preservar su fertilidad. Presentamos el primer caso de MIV realizado en Chile, en la Unidad de Medicina Reproductiva de Clínica Monteblanco, en una paciente con sospecha de resistencia ovárica a la FSH y quien, con el consentimiento de sus padres, realizó este procedimiento para preservar su fertilidad a futuro.

Oocyte in vitro maturation (IVM) is an assisted reproductive technology in which immature oocytes are retrieved from antral follicles. It has been applied mainly in patients with an increased risk of ovarian hyperstimulation syndrome, particularly in patients with polycystic ovarian syndrome. Moreover, it has been proposed as an alternative approach for fertility preservation for oncological patients. We report the first IVM case in Chile, preformed at the Centre for Reproductive Medicine at Clínica Monteblanco, in a patient with suspected ovarian resistance to FSH, who with the consent of her parents, performed IVM to preserve her fertility.

A "freeze-all" embryo strategy after in vitro maturation: a novel approach in women with polycystic ovary syndrome?

OBJECTIVE: To assess the efficiency of a "freeze-all" embryo strategy after immature oocyte retrieval (OR) and in vitro maturation (IVM) in patients with polycystic ovary syndrome (PCOS). DESIGN: Retrospective case series. SETTINGS: University-based tertiary referral center. PATIENT(S): Seventy-nine consecutive PCOS patients undergoing IVM followed by vitrified-warmed embryo transfer (ET) over a 2-year period. INTERVENTION(S): All patients received 150 IU/d highly purified hMG for 3 consecutive days. There was no hCG trigger given before OR. All day-3 embryos of good morphologic quality were vitrified. Single or double ET was performed in 114 consecutive artificial cycles. The cumulative live birth rate (LBR) per patient was calculated, as well as the projected cumulative LBR. MAIN OUTCOME MEASURE(S): LBR per patient and per retrieved immature oocyte. RESULT(S): Mean age, body mass index, and antimüllerian hormone were 28.5 ± 3.5 years, 27.8 ± 7.1 kg/m(2), and 10.3 ± 5.5 µg/L, respectively. In total, 1,526 cumulus-oocyte complexes were retrieved. IVM yielded 800 metaphase II oocytes (52.4%), and 291 day-3 embryos were cryopreserved. Of these, 224 (76.9%) embryos were warmed. One hundred seventy-one survived (76.3%), and 105 ETs were performed. LBR per ET was 16.2% and the cumulative LBR per patient was 21.8%. LBR per retrieved immature oocyte was 1.1%. The projected LBR per patient was 24.2%. CONCLUSION(S): IVM followed by a "freeze-all" embryo strategy is a novel approach for women with PCOS. Patients who undergo IVM should be advised that each immature oocyte retrieved yields a 1.1% chance to achieve a live birth.

Corifollitropin alfa followed by rFSH in a GnRH antagonist protocol for poor ovarian responder patients: an observational pilot study.

OBJECTIVE: To identify whether women with poor ovarian response may benefit from treatment with corifollitropin alfa in a GnRH antagonist protocol. DESIGN: Retrospective pilot study. SETTING: University-based tertiary care center. PATIENT(S): Poor ovarian responders fulfilling the Bologna criteria developed by European Society for Human Reproduction and Embryology Consensus Group. INTERVENTION(S): Corifollitropin alfa (150 µg) followed by 300 IU rFSH in a GnRH antagonist protocol. MAIN OUTCOME MEASURE(S): Endocrinologic profile and ongoing pregnancy rates. RESULT(S): Among 43 women treated with corifollitropin alfa, mean E(2) levels showed an increasing pattern during the follicular phase, reaching 825 ng/L on the day of hCG administration, whereas FSH values showed a marked increase during the first 5 days, reaching a mean value of 35 IU/L and remaining above 20 IU/L during the late follicular phase. Cycle cancellation rate was 32.6% and embryo transfer rate 53.3%. Five patients (11.7%) had a positive hCG test and three (7%) had an ongoing pregnancy. Ongoing pregnancy rates were 11.1% per oocyte retrieval and 13% per embryo transfer. Ongoing pregnancy rates per patient did not significantly differ compared with a cohort of patients treated during 2011 with the standard protocol for poor responders in our center (short agonist-hMG) (7% vs. 6.3%). CONCLUSION(S): Treatment of poor ovarian responders, as described by the Bologna criteria, with corifollitropin alfa in a GnRH antagonist protocol results in low pregnancy rates, similarly to conventional stimulation with a short agonist protocol.

Developmental capacity of in vitro-matured human oocytes retrieved from polycystic ovary syndrome ovaries containing no follicles larger than 6 mm.

OBJECTIVE: To test the developmental competence of oocytes in a nonhCG-triggered in vitro maturation (IVM) system when oocyte-cumulus complexes (OCC) are retrieved from antral follicles with a diameter of <6 mm. DESIGN: Prospective cohort study. SETTING: Tertiary university-based referral center. PATIENT(S): From January 2010 to September 2011, 121 patients with polycystic ovaries/polycystic ovary syndrome underwent 239 IVM cycles in total. In 58 of these cycles (44 patients), all antral follicles had a diameter of <6 mm on the day of oocyte retrieval. INTERVENTION(S): NonhCG-triggered IVM of oocytes, fresh or vitrified/warmed embryo transfer (ET). MAIN OUTCOME MEASURE(S): Oocyte diameter, maturation rate, fertilization rate, embryo development and morphology, implantation rate, clinical pregnancy rate, ongoing pregnancy rate. RESULT(S): Oocyte retrieval yielded 16.7 OCC/cycle, and 50.8% of oocytes completed IVM. The mean oocyte diameter increased from 108.8 ± 4.3 µm to 111.9 ± 4.1 µm after IVM. Mean fertilization rate was 63.7%, and 45.4% of 2-pronuclei oocytes developed into a morphologically good-quality embryo on day 3 after intracytoplasmic sperm injection. Fresh ET resulted in two ongoing pregnancies (2/37; 5.4%). Deferred vitrified-warmed ET led to an ongoing pregnancy rate of 34.6% (9/24). Three healthy babies were born and eight pregnancies were still ongoing. CONCLUSION(S): Oocytes retrieved from follicles with a diameter of <6 mm grow during a 40-hour IVM culture can acquire full competence in vitro, as illustrated by their development into healthy offspring. Endometrial quality appears to be a crucial determinant of pregnancy after nonhCG-triggered IVM.

Clinical outcome of non-hCG-primed oocyte in vitro maturation treatment in patients with polycystic ovaries and polycystic ovary syndrome.

OBJECTIVE: To compare clinical outcomes of fresh embryo transfer (ET) and vitrified-warmed ET in an artificial endometrial priming cycle in patients with polycystic ovaries (PCO) or polycystic ovary syndrome (PCOS) who underwent oocyte in vitro maturation (IVM) in non-hCG-primed cycles. DESIGN: Prospective cohort study. SETTING: University-based tertiary referral center. PATIENT(S): Thirty-nine consecutive patients <37 years old with PCO or PCOS, who underwent 73 cycles of immature oocyte retrieval. INTERVENTION(S): Immature oocyte collection after ovarian stimulation with a cumulative dose of 450 IU uFSH or highly purified hMG, but without hCG priming. IVM of oocytes followed by ET if endometrium thickness ≥ 6 mm. Embryo vitrification at the cleavage stage. ET in an artificial cycle. MAIN OUTCOME MEASURE(S): Implantation rate (IR) and clinical pregnancy rate (CPR). RESULT(S): Fresh ET after IVM resulted in an IR of 6.9% (5/72) per ET and a CPR of 9.4% (5/53). ET of vitrified-warmed IVM embryos in an artificial cycle resulted in significantly better outcomes (IR 21.9% [7/32] and CPR 31.8% [7/22] per ET). CONCLUSION(S): A non-hCG-primed IVM system in PCO or PCOS performs poorly when embryos are transfered in a fresh cycle. Transfer of vitrified-warmed IVM embryos in an artificial cycle leads to significantly improved clinical outcomes. These data illustrate that IVM embryos in PCO or PCOS have good survival rates and suggest that hCG may be needed to support endometrial receptivity in the fresh IVM cycle.
