Risk of gestational trophoblastic neoplasia after hCG

While GTN after a molar pregnancy is usually diagnosed with serial β-hCG titers, imaging plays an important role in evaluation of local extent of disease and systemic surveillance. Imaging also plays a crucial role in detection and management of complications, such as uterine and pulmonary arteriovenous fistulas Postmolar GTN, which includes invasive mole and choriocarcinoma, develops in about 15% to 20% of complete moles, but in only 1% to 5% of partial moles.2,3,6,7The reported incidence of GTN after molar pregnancy is 18% to 29%.2,3,8,9This rate appears to be stable despite the progressively earlier diagnosis of complete HM.9Invasive moles arise from extension of HM into the myometrium via tissue or venous channels Definitions Gestational Trophoblastic Neoplasia (GTN)=Malignant Gestational Trophoblastic DiseaseIt is a spectrum of trophoblastic diseases that develops malignant sequelae.

Follow-up protocol Post-Evacuation of Molar Pregnancy Weekly hCG measurements until hCG becomes undetectable Once hCG is undetectable, 2 further specimens should be obtained at weekly intervals Then monthly for 6 months and the Objective: To develop human chorionic gonadotropin (hCG) criteria that determine a patient's risk of developing persistent gestational trophoblastic neoplasia (GTN) or achieving remission after partial mole evacuation. Study design: We used a database from the New England Trophoblastic Disease Center to analyze hCG levels from 284 women with partial molar pregnancies diagnosed between 1973 and.

Gestational Trophoblastic Disease: Clinical and Imaging

  1. Post-molar GTN is often curable [2], however late presentation of many cases may change the prognosis and response to chemotherapy. Although serial serum β-hCG titre measurement is considered an exceptional tumor marker for GTN, the compliance of patients differs and many cases are lost during follow up
  2. us 10% of the previous result) across four measurements over a 3-week period
  3. All post-molar GTN patients treated with first-line methotrexate and folinic acid (MTX/FA) were identified in a national cohort between 2009 and 2016. Data collected included age, FIGO score, the hCG levels at MTX-R, and treatment outcomes
  4. Invasive moles, also called post-molar GTN, are just one of the more worrisome forms of GTN with metastatic potential. For fewer than 1 in 5 women who has a complete molar pregnancy, the mole spreads beyond the lining of the uterus and into the muscular wall and cannot be removed by a D and C
  5. Most post-molar GTN patients will have a FIGO score of 0-6 and therefore be at low risk (LR) of developing disease resistant to single-agent chemotherapy with either methotrexate (MTX) or actinomycin D (ActD).
  6. Post-molar follow-up and diagnosis of trophoblastic neoplasia. Following uterine molar evacuation, patients are followed closely with weekly clinical evaluations and hCG monitoring. An ultrasound is only generally needed when there is an increase or plateau in hCG titers when evaluating a primary GTN site

Gestational trophoblastic neoplasia (GTN) (WHO/FIGO):1,2 defined by post-molar evacuation serum hCG monitoring or a tissue diagnosis of choriocarcinoma: Three or more serum hCG values without significant changes (plateau) over 4 weeks. A rise of serum hCG of 10% or more for two values over 3 weeks or longer Post-molar GTN • NCCN Guidelines: Repeat D&C or hysterectomy can be considered for (non-metastatic) persistent post-molar GTN. • Post-surgical surveillance: • hCG assay ever 2 weeks until 3 consecutive normal levels. • hCG assay monthly for 6 months following normalization Post-molar GTN after suction evacuation of molar pregnancies has been reported in 23 to 37% of women older than 40 years and 31 to 56% of women above 50 years of age [1]. In contrast, GTN following complete and partial moles have been reported in 20% and 5% of young women, respectively [2]

GTN, which is mostly invasive mole pathologically.2 The incidence of post-molar GTN is 15-24% and 0.5-5% after CHM and PHM, respectively. 3-10 Predictive factors for post-molar GTN are reportedly CHM, age, pretreatment human chorionic gonadotropin (hCG) level, uterine size GTN may develop after a molar pregnancy, a non-molar pregnancy or a live birth. The incidence after a live birth is estimated at 1/50 000. Because of the rarity of the problem, an average consultant obstetrician and gynaecologist may deal with only one new case of molar pregnancy every second year GTN. A molar pregnancy rarely may lead to gestational trophoblastic neoplasia which is a form of cancer but it is curable. A persistent GTD, usually identified by high levels of HCG, is also referred to as GTN. Symptoms. Extreme Nausea; Pain in the pelvic area; Irregular Bleeding in the first trimester. Excessive enlargement of the uterus

Another recent investigation of 204 sporadic hydatidiform moles in Canada also reported a significantly higher risk for post-molar GTN in patients with heterozygous complete moles (91.7%) compared. The NCCN Guidelines for Gestational Trophoblastic Neoplasia provides treatment recommendations for various types of GTD including hydatidiform mole, persistent post-molar GTN, low-risk GTN, highrisk GTN, and intermediate trophoblastic tumor.

Gestational Trophoblastic Disease (GTD) Part I: Molar

  1. Diagnosis of post-molar gestational trophoblastic disease or post-molar GTN was made following the 2002 WHO/FIGO criteria [21,22,23], when one of the following findings was observed: (1) a plateau.
  2. Six of the 24 patients developed post-molar GTN. The initial median progesterone level of 76 ng/ml in these six patients drawn at evacuation was significantly higher than the median of 18 ng/ml in those not developing GTN (P = 0.026). Additionally, the serum progesterone decreased to <5 ng/ml within a week of evacuation in 16/18 patients.
  3. Invasive mole is the most common form of post molar GTN. GTN incidence varies from 0.6-1.1 per 1000 pregnancies in Europe and North America, to 1 in 77 pregnancies and 1 in 57 deliveries in Indonesia (Chhabra, 2007). GTN may arise after an episode of molar pregnancy (15-20% of patients with complete mole and 1-5% with partial mole), of which 50.

  5. 8105 patients registered with a diagnosis of molar pregnancy between 2009 and 2016. GTN subsequently developed in 787 women but 178 were excluded using the criteria outlined above. Thus, 609 women commenced single-agent MTX/FA for confirmed post-molar GTN. At the start of treatment, the median age was 32 years (range 14
  6. Postpartum/post-delivery of non-molar pregnancy •GTN may develop after a molar pregnancy, a non-molar pregnancy or a live birth. •Any woman who develops persistent vaginal bleeding after a pregnancy event is at risk of having GTN. •A urine hCG test should be performed in all cases of persistent or irregular vaginal bleedin

Gestational Trophoblastic Disease - Diagnosis and work-up

Approximately 50% of cases of GTN arise from molar pregnancy, 25% from miscarriage or tubal pregnancy, and 25% from term or preterm pregnancy. Invasive mole and choriocarcinoma, which make up the vast majority of these tumors, always produce substantial amounts of human chorionic gonadotropin (hCG) and are highly responsive to chemotherapy with. Prophylactic administration of either Methotrexate or Actinomycin D at the time of or immediately after evacuation of a hydatidiform mole is associated with a reduction in incidence of post-molar GTN from approximately 15-20% down to 3-8% The incidence of post-molar GTN were 58 and 30%, respectively (total hysterectomy versus uterine evacuation, P = 0.094). In the other study [ 16 ], 38 older patients with HM were included, as a result, post-molar GTN developed in 40% of patients in evacuation group and 27.8% in hysterectomy group ( p > 0.05)

The present study aims at identifying an applicable longitudinal marker from the serum human chorionic gonadotropin (hCG) levels during 3 weeks after mole evacuation for predicting the gestational trophoblastic neoplasia (GTN) in patients with partial or complete molar pregnancy.In this historical cohort study, 201 documents of patients with hydatidiform mole (according to their pathological. Metastatic GTN, however, is rare after the complete evacuation of a molar pregnancy (4%), and while it only occurs in approximately 1 in 30,000 non-molar pregnancies, it is overall seen more frequently after a non-molar pregnancy. 6, 7. Risk factors for post-molar GTN include an HCG level greater than 100,000 mIU/mL, large theca lutein cysts. Since the exact time of GTN development is unknown, a model for a binary outcome is needed. There were 299 women in the uneventful group (GTN = 0), and 140 patients with a confirmed diagnosis of post molar GTN in the persistent trophoblastic disease (GTN = 1) group

With risk of postmolar GTN and non-compliance with follow-up. Chemoprophylaxis with methotrexate or dactinomycin is given only after evacuation of a hydatidiform mole and assessment of clinical and social risk factors. A clinical risk assessment is used to identify patients at low risk or high risk for developing post-molar GTN GTN can occur within 6 months after the HM mostly as an invasive mole. The incidence of GTN after HM (post-molar GTN) is reported to be 15-24% and 0.5-5% among patients with CHM and PHM, respectively [3,4,5,6,7,8,9 5, 6, 10, 11]. Invasive moles can be cured almost 100% of the time, but chemotherapy is necessary because it can metastasize to. Hazard ratios (HR) and 95% confidence intervals (CI) for variables associated with the occurrence of post-molar GTN and invasive mole were estimated by univariate and multivariate Cox proportional hazards models. RESULTS: From 1995 to 2016, 182 patients were diagnosed with molar pregnancy and underwent treatment While in the United States, initial staging with brain and abdomen-pelvis magnetic resonance imaging (MRI), and chest computed tomography (CT) is recommended, FIGO/EOTTD recommends that only pelvic-transvaginal Doppler ultrasound and chest X-ray should be initially requested in patients with post-molar GTN

A total of 2008 registered patients with ascertained types of HM were analysed. Cases of GTN occurring after normalisation of hCG were analysed. RESULTS A GTN developed in 239 out of 1980 HMs (12.1%) and 6 out of these 239 post-molar GTN (2.5%) were diagnosed after normalisation of hCG. The risk of GTN after normalisation of hCG was 0.34% (6. In a systematic review and meta-analysis, total hysterectomy, as compared to uterine evacuation, was found to be a better therapeutic method for patients with molar pregnancy above 40 years unless fertility was desired, in preventing post-molar gestational trophoblastic neoplasia with an OR of 0.19 (95% CI, 0.08-0.48; P = 0.0004) Jenna takes us today through the often confusing world of GTD (or GTN, or GTT). GTD encompasses several distinct disease entities, including complete and partial molar pregnancy, invasive moles, gestational choriocarcinoma, and placental-site trophoblastic tumors (PSTT). Molar Pregnancies are a form of non-invasive GTD, and will be encountered. Gestational trophoblast disease (GTD) describes a set of diseases originating in placental tissue, specifically the chorionic villi and extravillous trophoblast. Other terms for this group include gestational trophoblastic neoplasia (GTN), and gestational trophoblastic tumor (GTT) Conclusions: In this study, C/S was a strong risk factor for occurrence of post-molar GTN and invasive mole. Aggressive treatment, such as multi-agent chemotherapy or hysterectomy, can be considered for hydatidiform moles in patients with a C/S history

There were 299 women in the uneventful group (GTN =0), and 140 patients with a confirmed diagnosis of post molar GTN in the persistent trophoblastic disease (GTN =1) group. Serum hCG levels (ng/mL) taken between two and seve In post-molar GTN, tumor activity continues despite uterine evacuation of a hydatidiform mole as measured by subsequent unaltered high or even surging BhCG concentrations in the blood. 15 While the current standard of care includes the use of chemotherapy medication as first line therapy for post-molar GTN patients, second curettage has been.

Moreover, in the present series, all post-molar GTN remain in remission. CONCLUSION: This study demonstrates that increasing the hCG cut-off from ≤300 to ≤1000 IU/l for choosing patients for ActD following MTX-R spares more women with GTN from the greater toxicity of EMA/CO without compromising 100% survival outcomes Furthermore, hysterectomy decreases the risk for post-molar GTN to approximately 3.5% from the anticipated 20% following suction curettage . Nevertheless, all patients should be monitored after hysterectomy because it does not completely eliminate the potential for post-molar GTN

Gestational Trophoblastic Disease: Follow-Up Care Cancer

Gestational trophoblastic neoplasia (GTN) Hydatidiform Moles. A hydatidiform mole is also known as a molar pregnancy. In a molar pregnancy, there is a problem with the fertilized egg, and there is an overproduction of trophoblast tissue. This excess trophoblast tissue grows into abnormal masses that are usually benign but can sometimes turn. GTN: Clinical Presentation/Diagnosis 50% occur after molar pregnancy 50% occur after spontaneous abortion, ectopic pregnancy, term pregnancy GTN after Non-Molar Pregnancy Abnormal vaginal bleeding Metastatic site bleeding (liver, spleen, intestines, lung, brain) Pulmonary symptoms Neurologic sign Invasive mole is the most common form of post molar GTN. GTN incidence varies from 0.6-1.1 per 1000 pregnancies in Europe and North America, to 1 in 77 pregnancies and 1 in 57 deliveries in Indonesia (Chhabra, 2007). GTN may arise after an episode of molar pregnancy (15-20% of patients with complete mole and 1-5% with partial mole), of which 50. 5 Surgical Treatment of Molar Pregnancy 3 6 Histological examination of Products of Conception 4 7 Initial Assessment 4 8 Follow-up in Molar Pregnancy 4 19 Chemotherapy in GTN 8 20 Follow-up post chemotherapy 9 21 Advice to Patients after chemotherapy 9 22 Pregnancy after chemotherapy for GTN 11 23 Prognosis in GTN 11 Acknowledgements.

Pregnancies resulting in repeat molar gestation also have an increased risk of persistent GTN. An increase in the incidence of congenital anomalies after chemotherapy has not been seen Gestational trophoblastic disease, although highly curable, is an emotionally traumatic event in a women's life, not only because of the pregnancy loss, but also because of the fear of cancer. Treatment of malignant GTD can impact significantly on her self-image and her relationship with her spouse/significant other, family, and friends 2.7. Diagnosis of post-molar GTN Diagnosis of GTN includes an increase in hCG levels after evacuation of HMs and/or histologically diagnosed as gestational choriocarcinoma or invasive mole, ETT, or PSTT; it resents clinical or radiological evidence of metastasis. To diagnose post-molar GTD, different modalities of hCG Post-molar GTN can spread to other organs — most often the lungs, which happens about 4 percent of the time. Choriocarcinoma, the most aggressive form of GTN, is a tumor that can grow quickly and spread to other organs, including the brain, lungs and vagina. About half of cases follow molar pregnancy, and a quarter develop after miscarriage. Studies were included if they: 1) were human studies, 2) explicitly indicated exposure to hysterectomy, 3) explicitly indicated control to uterine evacuation, 4) explicitly indicated the participants were older patients with HM being at least 40 years in age, 5) compared the outcome of interest as the incidence of post-molar GTN

It is of utmost importance to have an organizational structure, that promotes accurate detection of molar pregnancies and careful post-molar surveillance, to ensure early detection, and thus early treatment, of women with GTN
  5. GTN should be suspected and further investigated in the setting of a preceding molar pregnancy when post-evacuation HCG levels plateau or rise. The vast majority of these cases of GTN are invasive moles with choriocarcinomas comprising less than 10% of cases. 1
  6. Results: Forty patients with post-molar GTN (74%), 11 patients with non-molar GTN (20.4%) and 3 patients with PSTT (5.6%) were included in the analysis. None of the ultrasonographic features evaluated (presence of endometrial disease; presence of a myometrial lesion; lesion morphology, diameter and vascularization) significantly differed.

It is proposed low-risk post-molar GTN patients with β-hCG > 400,000 IU/l may benefit from multi-agent chemotherapy . In a cohort of low-risk GTN patients, You et al. found choriocarcinoma pathology and calculated that individual β-hCG clearance ≤0.37 I/day was a major independent predictive factor for MTX resistance risk GTN arises when the normal regulatory mechanisms controlling the proliferation and invasiveness of trophoblastic tissue are lost. Post hydatidiform mole gestational trophoblastic neoplasia is diagnosed by rising hCG and abnormal radiology suggesting the presence of molar tissue Post-molar GTN was studied at the Mansoura University Hospital, Mansoura, Egypt, with support from the Erasmus MC Cancer Institute, University Medical Center, Rotterdam, the Netherlands. The outcome of this study has implications for all women with GTN, and we would therefore like to share our experience METHODS: Sixteen patients with CHM and spontaneous regression, and 16 patients with CHM which progressed to post-molar GTN were selected. Immune cell composition and density of natural killer (NK) cells, natural killer T (NKT)-like cells, Cytotoxic T cells, T-Regulatory and T-Helper cells, were determined by multiplex immunohistochemistry (mIHC) Follow up with serial b-hCG is a requirement for diagnosis of post-molar GTN. 14 The RANZCOG criteria for diagnosis of GTN after a molar pregnancy is: a rise of more than nine per cent across three consecutive weekly values over a period of two weeks; a plateau or fall of less than ten per cent across four weekly measurements over a period of.

10e20% of CM and <5% of PM progress to post-molar gestational trophoblast neoplasia (GTN) requiring chemotherapy. Therefore, correct differential diagnosis of CM and PM is important for the management of these patients and early detection of GTN. The mechanism by which hydatidiform mole progresses to invasive mole or choriocarcinoma remains. Close follow-up aims to maximise detection of post-molar gestational trophoblastic neoplasia (GTN) by identifying plateaued or newly rising beta hCG levels. A 6- to 12-month period of negative surveillance after serum beta hCG nadir is generally adequate to exclude post-molar GTN Forty cases of complete mole, after evacuation and follow up of serum human chorionic gonodotrophin (β-hCG) titre until it reached zero level (group I) and forty post molar GTN cases (group II) were included in the study. Doppler ultrasound of the subendometrial and intramural blood flow was done for all cases of group I and II GTN. 15. Lines 314-315: This is where the terminology is confusing. The term proliferative moles without myometrial invasion refers to post-molar GTN? If so, please use the consistent term.
