Uterine epithelioid trophoblastic tumor with the main manifestation of increased human chorionic gonadotropin:A case report

BACKGROUND Epithelioid trophoblastic tumor(ETT)is an extremely rare malignant gestational trophoblastic neoplasm commonly presenting with abnormal vaginal bleeding,abdominal pain,and increased human chorionic gonadotropin(hCG).This study reported a case of uterine ETT with the main manifestation being increased hCG.CASE SUMMARY A 39-year-old female was referred to the Ningbo Maternal and Child Hospital of China in December 2022,complaining of increased hCG levels for 1 month.Magnetic resonance imaging revealed gestational trophoblastic tumor,and hysteroscopic electrotomy and curettage of intrauterine hyperplasia were performed.The patient was diagnosed with uterine ETT through postoperative pathological examination and immunohistochemical results.Total laparoscopic hysterectomy and bilateral salpingectomy were performed,and hCG levels returned to normal.The patient was without recurrence during the postoperative 3-month follow-up.CONCLUSION This study reported a case of uterine ETT with the main manifestation being increased hCG,highlighting that ETT should be considered in the presence of abnormal hCG.A total laparoscopic hysterectomy is recommended.

Second-trimester maternal β-human chorionic gonadotropin level associated with subsequent development of pregnancy-induced hypertension

Objective:To determine whether maternal β-human chorionic gonadotropin(β-hCG) level in second-trimester may be associated with subsequent development of pregnancy-induced hypertension(PIH).Methods:Seven hundred and sixty-two women in mid-trimester were to have maternal urine β-hCG standardized concentrations and maternal serum β-hCG measurements.Their case histories were recorded and reviewed from mid-trimester to delivery.The relation was observed between maternal urine,serum markers and subsequent development of PIH.Results:Among 762 women,504 cases were normal pregnancies,42 cases had PIH,94 cases had premature rupture of membrane (PROM),69 cases had preterm delivery (PD),53 other cases were excluded by various reasons.The levels of maternal urine,serum β-hCG in PIH were (61.75±9.78) IU/L and (304.56±54.17) ng/mg respectively,which were higher significantly than normal pregnancy group ([20.65±7.61] IU/L and [146.34±47.81] ng/mg,P<0.05).When maternal serum,urine β-hCG levels ≥2 MOM(multiple of mean),the incidences of developing PIH were increased significantly as compared with those of β-hCG <2 MOM women.The incidence of PIH increased from 5.1% in pregnancies with urine β-hCG ≥2 MOM to 11.7% in cases with urine β-hCG ≥4 MOM.Conclusion:The elevation of maternal mid-trimester urine,serum β-hCG levels is not only an early signal for dysfunction of placenta but also a dangerous signal for development of PIH.Second-trimester maternal urine β-hCG measurement proves to be superior to serum marker in clinical prediction.

Effects on Cell Viability and on Apoptosis in Tumoral(MCF-7)and in Normal(MCF10A)Epithelial Breast Cells after Human Chorionic Gonadotropin and Derivated-Angiotensin Peptides Treatments

Angiotensin-(1 - 7) [Ang-(1 - 7)] is an endogenous heptapeptide hormone of the renin-angiotensin system that has antiproliferative properties. The aim of this work was to evaluate the anti-proliferative and pro-apoptotic properties of Ang-(1 - 7) and of Ang-(1 - 7)-substituents 9-fluorenylmethyloxycarbonyl (Fmoc) e Ang II-derivatives containing the TOAC (2,2,6,6-tetramethylpiperidine-N-oxyl-4-amino-4-carboxylic acid) in normal (MCF10A) and in tumoral (MCF7) epithelial mammary cell lines. Both cell lines received an hCG and angiotensin peptides 24-hour treatment, in combination or alone followed by cell viability, apoptosis and cell cycle assays performed by flow cytometer (GUAVA). After hCG, Ang-(1 - 7), hCG + Ang-(1 - 7) and hCG + Ang-(1 - 7)-Fmoc treatments, MCF7 displayed cell viability decrease and mid-apoptosis increase. We also observed cell viability decrease in MCF10A after Ang-(1 - 7), Ang-(1 - 7) Fmoc and hCG + AngII Toac treatments. These cells had an increase in late apoptosis and necrosis after AngII Toac, hCG + Ang-(1 - 7) and hCG + Ang-(1 - 7)-Fmoc treatments. Regarding the cell cycle analysis, we did not observed any changes in cell cycle phases. In summary, cell viability was decreased and apoptosis (initial, mid and late) was increased after hCG and/or Ang-(1 - 7) peptides treatments. These results point out hCG and Ang-(1 - 7) as effective compounds to inhibit cell proliferation, since they decrease cell viability and increase apoptosis in both normal and in tumoral breast cells, being the effect more pronounced in the tumoral cell line. Our results support the idea of investigating more closely the putative use of these compounds as novel therapeutic agents for breast cancer.

Expression of Beta-Human Chorionic Gonadotropin Genes in Renal Cell Cancer and Benign Renal Disease Tissues

To study the expression of beta-human chorionic gonadotropin (βhCG) genes in renal cell carcinomas (RCC) and benign renal disease tissues, nested reverse transcription-polymerase chain reaction (RT-PCR) and restriction endonuclease analysis were employed to detect the expression of βhCG genes in 44 cases of RCC tissues and 24 cases of benign renal disease tissues It was found that 52% RCC samples revealed positive for βhCG mRNA expression Positive rate in advanced stage and poorly differentiated RCC was higher, but there was no significant difference The positive rate of βhCG mRNA expression was 54% in 24 cases of benign renal tissues, including 3 cases out of 6 polycystic kidneys, 7 cases out of 13 renal atrophies, 2 cases out of 2 oncocytomas and 1 case out of 2 pyonephrotic kidneys β7 was most frequently transcribed subtype gene independent on the histology These findings suggested βhCG gene transcription is not only involved in RCC but also in benign renal diseases

The Study on Immuno-response and Antisera Properties of Recombinant β-subunit of Human Chorionic Gonadotropin in C57 Black Mouse

In this study, the immuno-response of recombinant hCG-β and natural hCGβ was comparatively investigated by using Freund's adjuvant. The results showed that, the properties and merits of the antibodies elicited by both kinds of hCG-β were similar. The antisera had high affinity for binding with hCG (Kαγβ≈5.86×108/mol/L, Kαβ≈8.18×108/mol/L), and were found to be effective in inhibiting the binding of 125I-hCG to receptors in rat testes. Results also indicated that, similar to the antisera induced by natural hCG-β, the recombinant hCG-β induced antisera had capacity of neutralizing the biological activities of hCG. Recombinant hCG-β could be used as an immunogen for contraceptive vaccine.

Predictive Value of Initial Serum Human Chorionic Gonadotropin Levels for Pregnancies after Single Fresh and Frozen Blastocyst Transfer

As one of the earliest markers for predicting pregnancy outcomes, human chorionic gonadotropin(h CG) values have been inconclusive on reliability of the prediction after frozen and fresh embryo transfer(ET). In this retrospective study, patients with positive h CG(day 12 after transfer) were included to examine the h CG levels and their predictive value for pregnancy outcomes following 214 fresh and 1513 vitrified-warmed single-blastocyst transfer cycles. For patients who got clinical pregnancy, the mean initial h CG value was significantly higher after frozen cycles than fresh cycles, and the similar result was demonstrated for patients with live births(LB). The difference in h CG value existed even after adjusting for the potential covariates. The area under curves(AUC) and threshold values calculated by receiver operator characteristic curves were 0.944 and 213.05 m IU/m L for clinical pregnancy after fresh ET, 0.894 and 399.50 m IU/m L for clinical pregnancy after frozen ET, 0.812 and 222.86 m IU/m L for LB after fresh ET, and 0.808 and 410.80 m IU/mL for LB after frozen ET with acceptable sensitivity and specificity, respectively. In conclusion, single frozen blastocyst transfer leads to higher initial h CG values than single fresh blastocyst transfer, and the initial h CG level is a reliable predictive factor for predicting IVF outcomes.

How and Why Do Gestational Trophoblastic Neoplasms Overproduce Human Chorionic Gonadotropin?

From the published data, the present mini-review attempts to answer two fundamental questions about the gestational trophoblastic neoplasms. In addition, it extrapolates the findings to other cancers that produce small amounts of hCG and how a novel therapies could be developed.

Effect of different fertilization time after human chorionic gonadotropin injection on fertilization outcome of patients in vitro fertilizationembryo transfer

Objective:To explore the effect of different fertilization time after human chorionic gonadotropin(HCG)injection on the outcome of fertilization in vitro fertilization-embryo transfer(IVF-ET).Methods:One thousand one hundred and forty IVF-ET cycles from January 2016 to August 2018 were analyzed retrospectively.According to the different fertilization time after injection of HCG divided into four groups:Group A(38.0 h~39.0 h),Group B(39.1 h~40.0 h),Group C(40.1 h~41.0 h),and Group D(41.1 h~42.0 h).The normal fertilization rate,the normal cleavage rate,the embryo utilization rate,the high-quality embryo rate,the clinical pregnancy rate,the implantation rate,and the spontaneous abortion rate were analyzed among the groups.Then we investigated the effect of different promotion methods on the outcome of fertilization during the optimal fertilization time.Results:There was no significant difference in 2PN cleavage rate,available embryo rate,clinical pregnancy rate,implantation rate and abortion rate among the four groups(P>0.05).The high-quality embryo rate in Group D(44.6%)was the highest,and was significantly different among the four groups(P<0.05).The normal fertilization rate in Group D(71.6%)was the highest,and was significantly different among the four groups(P<0.05).The normal fertilization rate(78.1%)of antagonist group was significantly higher than other groups(P<0.05).Conclusion:The different fertilization time after HCG injection have effects on high-quality embryo rate and normal fertilization rate of patients in IVF-ET.The appropriate fertilization time of patients in IVF-ET was 41 h~42 h after HCG injection in our reproductive center,improved the clinical pregnancy rate and reduced the early abortion rate.The GnRH-ant protocol is superior to other protocol in IVF-ET.

Live births from in vitro fertilization-embryo transfer following the administration of gonadotropin-releasing hormone agonist without gonadotropins:Two case reports

BACKGROUND The prevalence of female infertility between the ages of 25 and 44 is 3.5%to 16.7%in developed countries and 6.9%to 9.3%in developing countries.This means that infertility affects one in six couples and is recognized by the World Health Organization as the fifth most serious global disability.The International Committee for Monitoring Assisted Reproductive Technology reported that the global total of babies born as a result of assisted reproductive technology procedures and other advanced fertility treatments is more than 8 million.Advancements in controlled ovarian hyperstimulation procedures led to crucial accomplishments in human fertility treatments.The European Society for Human Reproduction and Embryology guideline on ovarian stimulation gave us valuable evidence-based recommendations to optimize ovarian stimulation in assisted reproductive technology.Conventional ovarian stimulation protocols for in vitro fertilization(IVF)–embryo transfer are based upon the administration of gonadotropins combined with gonadotropin-releasing hormone(GnRH)analogues,either GnRH agonists(GnRHa)or antagonists.The development of ovarian cysts requires the combination of GnRHa and gonadotropins for controlled ovarian hyperstimulation.However,in rare cases patients may develop an ovarian hyper response after administration of GnRHa alone.CASE SUMMARY Here,two case studies were conducted.In the first case,a 33-year-old female diagnosed with polycystic ovary syndrome presented for her first IVF cycle at our reproductive center.Fourteen days after triptorelin acetate was administrated(day 18 of her menstrual cycle),bilateral ovaries presented polycystic manifestations.The patient was given 5000 IU of human chorionic gonadotropin.Twenty-two oocytes were obtained,and eight embryos formed.Two blastospheres were transferred in the frozen-thawed embryo transfer cycle,and the patient was impregnated.In the second case,a 37-year-old woman presented to the reproductive center for her first donor IVF cycle.Fourteen days after GnRHa administration,the transvaginal ultrasound revealed six follicles measuring 17-26 mm in the bilateral ovaries.The patient was given 10000 IU of human chorionic gonadotropin.Three oocytes were obtained,and three embryos formed.Two high-grade embryos were transferred in the frozen-thawed embryo transfer cycle,and the patient was impregnated.CONCLUSION These two special cases provide valuable knowledge through our experience.We hypothesize that oocyte retrieval can be an alternative to cycle cancellation in these conditions.Considering the high progesterone level in most cases of this situation,we advocate freezing embryos after oocyte retrieval rather than fresh embryo transfer.
