Systematic review of health-related quality of life and patient-reported outcome measures in gestational trophoblastic disease: a parallel synthesis approach

Patients' experience of menopausal symptoms post-chemotherapy treatment for gestational trophoblastic neoplasia

PURPOSE

We aimed to explore patient's experience of chemotherapy-induced menopausal symptoms; to ascertain how patients tried to alleviate their symptoms and how health professionals supported them in order to identify current unmet needs.

METHODS

We designed a retrospective cross-sectional exploratory study of a sample of 11 women who received multi-agent combination chemotherapy for Gestational Trophoblastic Neoplasia. Postal surveys using the Greene Climacteric Scale (GCS) questionnaire followed up by semi-structured telephone interviews were used. Framework analysis technique was used to generate descriptions of patient's experiences.

RESULTS

Symptoms of feeling tired or lacking in energy, loss of interest in sex, muscle and joint pains and difficulty in concentrating affected participants the most. The menopausal symptoms appear to be temporary; symptoms such as hot flushes and night sweats seem to subside with resumption of menses. Others are more gradual with some evidence that mental health takes longer to recover. Regarding potential symptoms, some women do not retain the information given to them at discharge following end of treatment, which GTD services need to take into consideration when supporting patients.

CONCLUSION

Patients need to be more optimally prepared for post-chemotherapy recovery with each patient's needs and support being individually tailored. How information is discussed and disseminated needs improving to ensure patients retain the information they receive at discharge. Recommendations include the creation of menopause information booklet, alongside further developing virtual nurse-led follow up clinics post chemotherapy.

Carbon-coated selenium nanoparticles for photothermal therapy in choriocarcinoma cells

Choriocarcinoma can be cured by chemotherapy, but this causes resistance and severe side effects that bring about physical and psychological consequences for patients. Therefore, there is still an urgent need to find other alternative minimally invasive therapies to halt the progression of choriocarcinoma. Novel carbon-coated selenium nanoparticles (C-Se) were successfully synthesized for choriocarcinoma photothermal therapy. C-Se combined with near-infrared laser irradiation can inhibit the proliferation of human choriocarcinoma (JEG-3) cells and induce cell apoptosis. C-Se killed cells and produced ROS under near-infrared laser irradiation. Finally, the therapeutic mechanism of C-Se + laser was explored showing that C-Se + laser influenced numerous biological processes. Taken together, C-Se exhibited significant potential for choriocarcinoma photothermal therapy.

Psychological impact over time of women with pregnancy loss due to gestational trophoblastic disease compared with miscarriage

OBJECTIVES

Pregnancy loss, occurring after miscarriage or after gestational trophoblastic disease, has a psychological impact. Besides pregnancy loss, women diagnosed with gestational trophoblastic disease have to deal with a prolonged period of follow-up and potential advice to postpone a future pregnancy. We studied the severity and course of the psychological impact after gestational trophoblastic disease and miscarriage, to identify whether women with gestational trophoblastic disease need different psychological care.

METHODS

A prospective multicenter study using online questionnaires was performed. Women diagnosed with gestational trophoblastic disease or miscarriage received the following questionnaires directly after diagnosis, and after 6, 6, and 12 months: a self-report questionnaire, the Hospital Anxiety and Depression Scale (HADS), the Impact of Event Scale, and the Reproductive Concerns Scale.

RESULTS

74 women with gestational trophoblastic disease and 76 women with miscarriage were included. At baseline, the proportion of women scoring above the cut-off level for the anxiety subscale of the HADS and for the Impact of Event Scale was significantly higher for women with gestational trophoblastic disease than for women after miscarriage (43.2% vs 28.9%, p=0.02 and 87.8% vs 78.9%, p=0.03, respectively). During follow-up, the differences between both groups vanished and only the Impact of Event Scale after 12 months remained significantly different between women with gestational trophoblastic disease and women after miscarriage (62.7% vs 37.3%, p=0.005). All outcomes, except the Reproductive Concerns Scale, showed a significant decline. However, in women who scored above the cut-off level on the HADS-total or Impact of Event Scale at baseline, and women with psychological or psychiatric history, significant higher scores persisted.

CONCLUSION

Although women with gestational trophoblastic disease at baseline had more anxiety and distress than women after miscarriage, no significant differences were seen using the HADS-total after 12 months. Using the HADS or Impact of Event Scale directly after pregnancy loss is helpful to identify women at risk of remaining psychological symptoms to provide them with extra psychological support.

Symptoms of anxiety and depression in women with gestational trophoblastic disease compared to women who had a miscarriage: a cross-sectional study

This study was conducted between March 2020 and February 2021 to analyze anxiety and depression symptoms in 64 women with gestational trophoblastic disease (GTD) and 99 women who had miscarried. The Hospital Anxiety and Depression Scale (HADS) was applied by telephone three months after pregnancy loss. Multivariate analysis was performed using hierarchical logistic regression to evaluate associations between variables. Probable anxiety (HADS-A ≥ 8) and depression (HADS-D ≥ 8) were found in 53.1% and 43.8% of the GTD group and 49.5% and 39.4% of the miscarriage group, with no difference between the groups. Severe symptoms of anxiety (HADS-A 15-21) and depression (HADS-D 15-21) were found, respectively, in 12.5% and 4.7% of the GTD group and in 9.1% and 4.0% of the miscarriage group, also with no difference between the groups. Lack of partner support proved a risk factor for anxiety and depression, while poor education increased the risk of depression symptoms 3.43-fold following pregnancy loss. In conclusion, three months after pregnancy loss the frequency of anxiety and depression symptoms was similarly high in both groups, with poor education and lack of partner support being significant risk factors for the subsequent development of psychiatric morbidity.

Gestational trophoblastic neoplasia: does centralization of care impact clinical management?

OBJECTIVE

International societies advocate for gestational trophoblastic neoplasia referral to designated expert centers. This study assessed the impact of centralization of trophoblastic care on clinical outcomes.

METHODS

A centralized program was implemented in 2018 at two affiliated academic hospitals, Princess Margaret Cancer Center and Mount Sinai Hospital. A retrospective analysis of patients treated between 2000 and 2022 was performed and the clinical outcomes were compared before (2000-2017) and after (2018-2022) centralization. Statistical analyses were performed with significance set as p<0.05.

RESULTS

A total of 94 patients with trophoblastic neoplasia were included: 60 pre-centralization and 34 post-centralization, 79.8% low-risk and 18.1% high-risk. Centralization led to significant improvement for: (1) accurate score documentation (from 37.9% to 89.3%,); (2) contraception counseling (from 67.2% to 96.7%); (3) median time from diagnosis to chemotherapy (from 9 days to 1 day); and (4) incomplete follow-up (from 20.7% to 3.3%) (all p<0.05). First-line chemotherapy for low-risk neoplasia was dactinomycin in 47.9% and 87.0% pre- and post-centralization, respectively (p=0.005). The median number of chemotherapy cycles decreased from seven to four (p=0.01), and the median number of consolidation cycles increased from two to three (p<0.001). Serum human chorionic gonadotropin (hCG) levels of 10 000-100 000 IU/L were significantly associated with longer time to hCG normalization and higher risk of resistance to first-line chemotherapy compared with hCG levels <1000 IU/L.

CONCLUSION

Centralization of trophoblastic neoplasia care leads to greater guideline compliance, faster chemotherapy initiation, fewer chemotherapy cycles with optimized consolidation, and enhanced surveillance completion. This supports the establishment of trophoblastic neoplasia expert centers.

Management of trophoblastic tumors : review of evidence, current practice, and future directions

INTRODUCTION

Gestational trophoblastic neoplasia (GTN) is a group of rare tumors characterized by abnormal trophoblastic proliferation following pregnancy including invasive moles, choriocarcinomas, and intermediate trophoblastic tumors (ITT). Although the treatment and follow-up of GTN has been heterogeneous, globally the emergence of expert networks has helped to harmonize its management.

AREAS COVERED

We provide an overview of the current knowledge, diagnosis, and management strategies in GTN and discuss innovative therapeutic options under investigation. While chemotherapy has been the historical backbone of GTN treatment, promising drugs such as immune checkpoint inhibitors targeting the PD-1/PD-L1 pathway and anti-angiogenic tyrosine kinase inhibitors are currently being investigated remodeling the therapeutical landscape of trophoblastic tumors.

EXPERT OPINION

Chemotherapy regimens for GTN have potential long-term effects on fertility and quality of life, making innovative and less toxic therapeutic approaches necessary. Immune checkpoint inhibitors have shown promise in reversing immune tolerance in GTN and have been evaluated in several trials. However, immunotherapy is associated with rare but life-threatening adverse events and evidence of immune-related infertility in mice, highlighting the need for further research and careful consideration of its use. Innovative biomarkers could help personalize GTN treatments and reduce chemotherapy burden in some patients.

Efficacy analysis of single-agent carboplatin AUC4 2-weekly as second-line therapy for methotrexate-resistant (MTX-R) low risk gestational trophoblastic neoplasia (GTN)

BACKGROUND

Approximately one-third of patients with low-risk Gestational Trophoblastic Neoplasia (WHO 0-6) develop methotrexate-resistance (MTX-R). In the UK, subsequent treatment with either actinomycin-D (ActD) or multi-agent combination chemotherapy has depended on whether the hCG was above or below an hCG threshold. To reduce exposure to combination chemotherapy (CC), over the years the UK service has raised this threshold as well as using single-agent carboplatin AUC6 3-weekly at MTX-R instead of CC. Updated results for carboplatin demonstrate an 86% complete hCG response (hCG CR) but associated with haematological dose-limiting toxicity.

METHODS

In 2017, single-agent carboplatin became the national standard second-line treatment following MTX-R at hCG of >3000 IU/L. Carboplatin was changed to two-weekly AUC4 scheduling and continued until normal hCG plus 3 consolidation cycles. For patients failing to respond, CC (Etoposide-Actinomycin-D or EMA-CO) was introduced.

RESULTS

22 evaluable patients with a median hCG at MTX-R of 10,147 IU/L (IQR 5527-19,639) received carboplatin AUC4 2-weekly (median no. of cycles = 6, IQR 2-8). Of these, 36% achieved a hCG CR. All 14 non-CR patients were cured with subsequent CC; 11 and 2 patients with 3rd line and 4th line CC respectively and 1 patient following 5th line CC and hysterectomy. Overall survival remains 100%.

CONCLUSION

Carboplatin is not sufficiently active in the second-line treatment of low-risk MTX-resistant GTN. New strategies are required to increase hCG CR and spare more toxic CC regimens.

Current chemotherapeutic options for the treatment of gestational trophoblastic disease

INTRODUCTION

Gestational trophoblastic neoplasia (GTN) is a rare tumor that arises from trophoblastic tissues with high remission rates after chemotherapy treatment. GTN can develop from any gestational events, such as miscarriage, ectopic pregnancy, and preterm/term pregnancy, but is more frequent after hydatidiform mole. The sensitivity of this tumor to chemotherapy and the presence of an exceptional tumor marker allow high remission rates, especially when patients are treated in referral centers.

AREAS COVERED

Observational, retrospective, prospective, systematic reviews, and meta-analysis studies focusing on GTN treatment. We searched PubMed, Medline, and the Library of Congress from January 1965 to May 2022.

EXPERT OPINION

Early GTN diagnosis allows low-toxic and highly effective treatment. Even multimetastatic disease has high rates of remission with multiagent regimen chemotherapy. Surgery is reserved for uterine disease in patients who have completed childbearing, in cases of chemoresistance to multiagent regimens or in the rare cases of placental site trophoblastic tumor or epithelioid trophoblastic tumor. While resistance is managed by salvage chemotherapy, cases with limited clinical response to sequential regimens have been successfully treated with immunotherapy.

A scoping review of qualitative geographic information systems in studies addressing health issues

Qualitative Geographic Information Systems (QGIS) represent an emerging geospatial and qualitative approach to comprehensively understand health issues. This scoping review gathers evidence from 38 articles to illuminate when and how QGIS is used to address health issues. QGIS can contribute to recent health-related studies focusing on determinants of health and health equity at the community rather than individual level, highlight relationships between place and health, and encourage participation from people and communities in health-decision making. If more studies attempt to specify detailed data analysis methods and develop ways to use rich contexts of qualitative data, QGIS can provide greater scope for those working to solve health problems.

5-Fluorouracil and actinomycin D lead to erythema multiforme drug eruption in chemotherapy of invasive mole: Case report and literature review

RATIONALE

5-Fluorouracil (5-FU) and actinomycin D (ActD) are often used in chemotherapy for various cancers. Side effects are more common in bone marrow suppression, liver function impairment, and gastrointestinal responses. Skin effects are rare and easy to be ignored by doctors and patients, which can lead to life-threatening consequence.

PATIENT CONCERNS

We reported a 45-year-old woman patient developed skin erythema and fingernail belt in chemotherapy of 5-FU and ActD.

DIAGNOSIS

Erythema multiforme drug eruption.

INTERVENTIONS

Laboratory tests including blood and urine routine, liver and kidney function, electrolytes and coagulation function and close observation.

OUTCOMES

The rash was gone and the nail change returned.

LESSONS

Delays in diagnosis or treatment may lead to serious consequence. We should pay attention to the dosage of 5-FU and ActD, monitor adverse reactions strictly, to reduce occurrence of skin malignant events.

Experience of women on the Irish National Gestational Trophoblastic Disease Registry

OBJECTIVE

Gestational Trophoblastic Disease (GTD) is a rare pregnancy related disorder and the most curable of all gynaecological malignancies. GTD comprises the premalignant conditions of complete or partial hydatidiform mole known as molar pregnancy and a spectrum of malignant disorders termed gestational trophoblastic neoplasia. Clinical management and treatment in specialist centres is essential to achieve high cure rates and clinical guidelines recommend registration with a GTD centre as a minimum standard of care. National GTD registries are valuable repositories of epidemiological data and facilitate clinical audit, centralised pathology review and human chorionic gonadotropin (hCG) monitoring. This study sought the opinion of women enrolled on the Irish National GTD registry to inform future service development and establish a knowledge base for molar pregnancy in Ireland.

STUDY DESIGN

A cross-sectional survey using an anonymised questionnaire was distributed by post to all women on the GTD registry. The questionnaire was designed by a multidisciplinary team and consisted of twenty-five closed-ended questions and two open-ended questions to facilitate feedback. Data collected in the survey included information on the patient experience of registration, knowledge of molar pregnancy, diagnosis at their local hospital, hCG monitoring and overall satisfaction with the service.

RESULTS

The survey had a successful participation rate of 42.6% (215/504). Forty-nine percent (n = 106) of respondents rated a rapid hCG result as their top priority. Forty percent (n = 84) of women had concerns about future pregnancies but acknowledged that these were largely addressed by the GTD specialist nurses. A quarter of respondents reported that other medical professionals with whom they interacted during follow-up treatment did not understand their condition. Many women commented on the emotional stress of attending their local maternity unit for phlebotomy while dealing with pregnancy loss.

CONCLUSION

This study is unique in being the first survey of women on the Irish National GTD registry. It highlights the specific needs of women with molar pregnancy in terms of psychological support, bereavement counselling and peer support groups. It reveals a knowledge gap in molar pregnancy amongst healthcare professionals which should be considered in future planning of medical and nursing curricula.

The efficacy evaluation of initial chemotherapy for high-risk gestational trophoblastic neoplasm

In clinical practice, a large number of patients have failed to receive chemotherapy or combination therapy because of drug resistance, recurrence and metastasis of specific sites. Therefore, how to choose the initial chemotherapy individually and reduce the occurrence of drug resistance is the key to cure high-risk GTN. This study investigated the efficacy of chemotherapy based on 5-fluorouracil (5-FU) regimen and EMA/CO regimen as the initial chemotherapy regimen in the treatment of high-risk gestational trophoblastic neoplasms (high-risk GTN). The treatment status of high-risk GTN patients who received primary chemotherapy using 5-Fu regimens (FAV and FA regimens) or EMA/CO regimens at Cancer Hospital of China Medical University from 2002 to 2019 was retrospective analyzed. Regular follow-up was conducted to evaluate its efficacy and to analyze prognostic factors. There were a total of 87 high-risk patients, 75 in the 5-FU-based group and 12 in the EMA/CO group. The clinical characteristics of patients in both groups were not statistically significant (P > 0.05). The overall survival rate of all patients was 87.4%, the rate of serological complete remission (SCR) was 87.4%, the SCR rate of initial treatment was 75.9%, the recurrence rate was 7.9%, and the mortality rate was 12.6%. There were no statistical differences in overall survival rate, SCR rate, SCR rate of initial treatment, drug resistance rate, recurrence rate and mortality in the 5-FU group and the EMA/CO group (P > 0.05). The median follow-up was 106 months. Kaplan-Meier analysis showed that the 1-year survival rate, 5-year survival rate and 10-year survival rate in the 5-FU group were 91.9%, 84.3% and 84.3% respectively. The 1-year survival rate, 5-year survival rate and 10-year survival rate of the EMA/CO group were all 91.7%, and there was no statistical difference in the overall survival time between the 2 groups (P > 0.05). COX proportional stepwise regression analysis showed that only clinical staging was an independent risk factor of the prognosis of high-risk GTN (P = 0.003). Conclusion Both 5-FU regimen and EMA / CO regimen can be used as the first-line treatment for high-risk GTN patients, and their effects are similar. For high-risk GTN patients with drug resistance, EMA / CO, FAEV and PEB can be used as second-line salvage chemotherapy.

Association between gestational trophoblastic disease (GTD) history and clinical outcomes in in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycles

BACKGROUND

Gestational trophoblastic disease (GTD) usually affects young women of childbearing age. After treatment for GTD, 86% of women wish to achieve pregnancy. On account of the impacts of GTD and treatments as well as patient anxiety, large numbers of couples turn to assisted reproductive technology (ART), especially in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). But few studies have investigated whether a history of GTD affects the outcomes of IVF/ICSI in secondary infertile patients and how it occurs. We investigate whether a history of GTD affects the IVF/ICSI outcomes and the live birth rates in women with secondary infertility.

METHODS

This retrospective cohort study enrolled 176 women with secondary infertility who underwent IVF/ICSI treatment at the reproductive medical center of Nanjing Drum Tower Hospital from January 1, 2016, to December 31, 2020. Participants were divided into the GTD group (44 women with GTD history) and control group (132 women without GTD history matched from 8318 secondary infertile women). The control group and the study group were matched at a ratio of 3:1 according to patient age, infertility duration, number of cycles and body mass index (BMI). We assessed retrieved oocytes and high-grade embryos, biochemical pregnancy, miscarriage, ectopic pregnancy, gestational age at delivery, delivery mode and live birth rates.

RESULT(S)

We found a significantly reduced live-birth rate (34.1% vs 66.7%) associated with IVF/ICSI cycles in patients with a GTD history compared to those without a GTD history. The biochemical pregnancy and miscarriage rates of the GTD group were slightly higher than those of the control group. In addition, there was a difference in gestational age at delivery between the GTD and control groups (p < 0.001) but no differences in the mode of delivery (p = 0.267). Furthermore, the number of abandoned embryos in the GTD group was greater than that in the control group (p = 0.018), and the number of good-quality embryos was less than that in the control group (p = 0.019). The endometrial thickness was thinner (p < 0.001) in the GTD group. Immunohistochemistry (IHC) showed abnormal endometrial receptivity in the GTD group.

CONCLUSION(S)

The GTD history of patients undergoing IVF/ICSI cycles had an impact on the live-birth rate and gestational age at delivery, which might result from the thinner endometrium and abnormal endometrial receptivity before embryo transfer.

Advances in the diagnosis and early management of gestational trophoblastic disease

Gestational trophoblastic disease describes a group of rare pregnancy related disorders that span a spectrum of premalignant and malignant conditions. Hydatidiform mole (also termed molar pregnancy) is the most common form of this disease. Hydatidiform mole describes an abnormal conceptus containing two copies of the paternal genome, which is classified as partial when the maternal genome is present or complete when the maternal genome is absent. Hydatidiform mole typically presents in the first trimester with irregular vaginal bleeding and can be suspected on ultrasound but confirmation requires histopathological evaluation of the products of conception. Most molar pregnancies resolve without treatment after uterine evacuation, but occasionally the disease persists and develops into gestational trophoblastic neoplasia. Close monitoring of women after molar pregnancy, with regular measurement of human chorionic gonadotrophin concentrations, allows for early detection of malignancy. Given the rarity of the disease, clinical management and treatment is best provided in specialist centres where very high cure rates are achievable. This review looks at advances in the diagnosis and early management of gestational trophoblastic disease and highlights updates to disease classification and clinical guidelines. Use of molecular genotyping for improved diagnostic accuracy and risk stratification is reviewed and future biomarkers for the earlier detection of malignancy are considered.

Direct comparisons of efficacy and safety between actinomycin-D and methotrexate in women with low-risk gestational trophoblastic neoplasia: a meta-analysis of randomized and high-quality non-randomized studies

Background

Actinomycin-D (Act-D) and Methotrexate (MTX) are both effective first-line agents for low-risk gestational trophoblastic neoplasia (LRGTN) with no consensus regarding which is more effective or less toxic. The primary objective of this meta-analysis is to compare Act-D with MTX in the treatment of LRGTN.

Methods

We systematically searched electronic databases, conferences abstracts and trial registries for randomized controlled trials (RCTs) and high-quality non-randamized controlled trials (non-RCTs), comparing Act-D with MTX for patients with LRGTN. Studies were full-text screened for quality assessment and data extraction. Eligible studies must have reported complete remission rate. A fixed-effects meta-analysis was conducted to quantify the efficacy and safety of Act-D and MTX on odds ratios (ORs) and 95% confidence intervals (95%CIs), respectively.

Results

A total of 8 RCTs and 9 non-RCTs (1674 patients) were included. In terms of efficacy, Act-D is superior to MTX in complete remission (80.2% [551/687] vs 65.1% [643/987]; OR 2.15, 95%CI 1.70 to 2.73). In the stratified analysis, patients from RCTs and non-RCTs both had a better complete remission from Act-D-based regimen (RCTs: 81.2% [259/319] vs 66.1% [199/301], OR 2.17, 95%CI 1.49 to 3.16; non-RCTs: 79.3% [292/368] vs 65.0% [444/686], OR 2.14, 95%CI 1.57 to 2.92). In terms of safety, patients receiving Act-D had higher risks of suffering nausea (OR 2.35, 95%CI 1.68 to 3.27), vomiting (OR 2.40, 95%CI 1.63 to 3.54), and alopecia (OR 2.76, 95%CI 1.60 to 4.75). Notably, liver toxicity (OR 0.38, 95%CI 0.19 to 0.76) was the only one that was conformed to have a higher risk for patients receiving MTX. In addition, the pooled results showed no significant difference of anaemia, leucocytopenia, neutropenia, thrombocytopnia, constipation, diarrhea, anorexia, and fatigue between Act-D and MTX.

Conclusions

Our meta-analysis suggests that Act-D had better efficacy profile in general, and MTX had less toxicities in LRGTN. Future clinical trials should be better orchestrated to provide more valid data on efficacy and toxicity.

Ten steps to establish a national centre for gestational trophoblastic disease

PURPOSE OF REVIEW

Gestational trophoblastic disease (GTD) is a group of heterogeneous disorders characterized by abnormal proliferation of trophoblastic tissue. GTD is a rare disease that is curable in the vast majority of patients when managed appropriately. The aim of the review is to discuss the important steps necessary to establish a center of excellence for GTD.

RECENT FINDINGS

Care of patients with a rare disease is complicated by lack of strong evidence, scattering of patients across the country and limited expertise of medical professionals. The establishment of a center of excellence requires awareness of its benefit, funding, a solid business case and most of all dedicated clinicians. A multidisciplinary team and formulation of national guidelines are important steps before clinical pathways can be developed and treatment can be evaluated for improvement of care and research purposes. International embedding can facilitate the process and lead to the development of a (inter) national acknowledged sustainable center of excellence.

SUMMARY

Centers of excellence could optimize the care of patients with GTD and promote research.

The psychological impact of gestational trophoblastic disease: a prospective observational multicentre cohort study

OBJECTIVE

To evaluate the short-term psychological consequences of gestational trophoblastic disease (GTD).

DESIGN

A prospective observational multicentre cohort study.

SETTING

Nationwide in the Netherlands.

POPULATION

GTD patients.

METHODS

Online questionnaires directly after diagnosis.

MAIN OUTCOME MEASURES

Hospital Anxiety and Depression Scale (HADS), Distress Thermometer (DT), Impact of Event Scale (IES) and Reproductive Concerns Scale (RCS).

RESULTS

Sixty GTD patients were included between 2017 and 2020. Anxious feelings (47%) were more commonly expressed than depressive feelings (27%). Patients experienced moderate to severe adaptation problems in 88%. Patients who already had children were less concerned about their reproductivity than were patients without children (mean score 10.4 versus 15.0, P = 0.031), and patients with children experienced lower distress levels (IES mean score 25.7 versus 34.7, P = 0.020). In addition, patients with previous pregnancy loss scored lower for distress compared with patients without pregnancy loss (IES mean score 21.1 versus 34.2, P = 0.002).

DISCUSSION

We recommend that physicians monitor physical complaints and the course of psychological wellbeing over time in order to provide personalised supportive care in time for patients who have high levels of distress at baseline.

CONCLUSIONS

GTD patients experience increased levels of distress, anxiety and depression, suggesting the diagnosis has a substantial effect on the psychological wellbeing of patients. The impact of GTD diagnosis on intrusion and avoidance seems to be ameliorated in patients who have children or who have experienced previous pregnancy loss.

TWEETABLE ABSTRACT

Patients with gestational trophoblastic disease (GTD) experience short-term psychological consequences such as distress, anxiety and depression, suggesting that the diagnosis GTD has a substantial effect on the psychological wellbeing of patients. Various patient characteristics affect the impact of GTD diagnosis.

Psychological factors influencing emotional reactions to gestational trophoblastic disease: The role of coping mechanisms and illness perception

OBJECTIVE

Referring to Leventhal's common-sense model, this observational cross-sectional study aimed at investigating the relationship between illness mental representations, coping mechanisms and psychological distress in a sample of women with gestational trophoblastic disease (GTD).

METHODS

Thirty-eight women diagnosed with GTD (18 with hydatidiform mole; 20 with gestational trophoblastic neoplasia) were asked to complete the Illness Perception Questionnaire-Revised, the Coping Orientation to the Problems Experienced, the State-Trait Anxiety Inventory-Form Y and the Beck Depression Inventory-Short Form. Demographic and clinical information was collected through a self-report questionnaire.

RESULTS

The sample did not report significant symptomatic distress in relation to GTD. Correlation analysis showed that the Emotional representations subscale of the Illness Perception Questionnaire-Revised was significantly associated with both state anxiety and depression; avoidant coping significantly and positively correlated with anxiety and depression, as well as with illness emotional representations. Mediation analysis revealed significant indirect effects of avoidant coping on both anxiety and depression through the mediation of emotional representations.

CONCLUSION

Avoidant coping could lead women to develop emotional representations of illness characterised by negative affects, which in turn enhance distress levels. Results underline the importance to promote adaptive coping strategies, along with accurate illness perceptions, to foster better psychological adjustment to GTD.

M-EA (methotrexate, etoposide, dactinomycin) and EMA-CO (methotrexate, etoposide, dactinomycin / cyclophosphamide, vincristine) regimens as first-line treatment of high-risk gestational trophoblastic neoplasia

High-risk gestational trophoblastic neoplasia (GTN) is highly chemosensitive with an excellent prognosis with treatment. Historically in the United Kingdom, the high-risk regimens used have been M-EA (methotrexate, etoposide, dactinomycin) (Sheffield) and EMA-CO (methotrexate, etoposide, dactinomycin / cyclophosphamide, vincristine) (Charing Cross, London) with prior published data suggesting no difference in survival between these. Our Sheffield treatment policy changed in 2014, switching from M-EA to EMA-CO, aiming to reduce time in hospital, and harmonise UK practice. We aimed to report the toxicities, response rates and survival outcomes for 79 patients with high-risk GTN treated in the first-line setting with either M-EA (n = 59) or EMA-CO (n = 20) from 1998 to 2018. Median duration of treatment was similar (M-EA, 17.3 weeks (IQR 13.9-22.6) and 17.6 weeks (IQR 13.4-20.7) with EMA-CO. For M-EA, overall human chorionic gonadotrophin (hCG) complete response (CR) rate was 84.7% (n = 50/59). Two patients died of drug-resistant disease after several lines of multiagent chemotherapy; overall survival is 96.6% (median follow-up 10.4 years). For EMA-CO, overall hCG CR rate was 70%, overall survival is 100% (median follow-up 4 years). In our experience, patients treated with EMA-CO experienced an apparent increased incidence of neutropenia, non-neutropenic Grade 3-4 infection, peripheral neuropathy and more treatment delays and nights in hospital. Granulocyte-colony stimulating factor, after both EMA and CO arms, titrated to baseline neutrophil count improved the toxicity profile. Both treatment regimens are associated with excellent prognosis; selection of regimen may be further guided by individual patients' personal, social and family circumstances. There is further rationale to explore whether these regimens can be refined, such as 2-weekly EMA, to optimise patient experience and reduce toxicity while maintaining efficacy.

Psychological aspects and fertility issues of GTD

Gestational trophoblastic disease (GTD) represents a spectrum of rare pregnancy-related disorders, including both premalignant and malignant entities. Although GTD's medical outcomes have been widely explored, limited data are available regarding the related psychological, sexual, and fertility issues. The present chapter aims to enhance comprehension of the psychosocial impact of GTD by discussing the main quantitative and qualitative evidence available in this field. Although patients globally report a good quality of life, clinically significant levels of anxiety and depression have been consistently found across studies. Similarly, despite the quality of couple relationships being generally satisfactory, they often complain of a lack of sexual desire. Moreover, pregnancy loss may raise significant and long-term fertility-related concerns. Specific socio-demographic and clinical factors have been identified as predictors of psychosocial outcomes. At the clinical level, research suggests that there is a need to provide multidisciplinary care to patients.

A review of quality of life (QOL) assessments and indicators: Towards a "QOL-Climate" assessment framework

Quality of life (QOL), although a complex and amorphous concept, is a term that warrants attention, especially in discussions on issues that touch on the impacts of climate change and variability. Based on the principles of RepOrting standards for Systematic Evidence Synthesis, we present a systematic review aimed at gaining insights into the conceptualization and methodological construct of previous studies regarding QOL and QOL-related indexes. We find that (i) QOL assessments vary in terms of conceptual foundations, dimensions, indicators, and units of analysis, (ii) social indicators are consistently used across assessments, (iii) most assessments consider indicators that pertain to the livability of the environment, and (iv) QOL can be based on objective indicators and/or subjective well-being, and on a composite index or unaggregated dimensions and indicators. However, we also find that QOL assessments remain poorly connected with climate-related issues, an important research gap. Our proposed "QOL-Climate" assessment framework, designed to capture the social-ecological impacts of climate change and variability, can potentially help fill this gap.

A comprehensive analysis of gestational trophoblastic neoplasia trials posted at online clinical trial registries

OBJECTIVE

We conducted a comprehensive analysis of gestational trophoblastic neoplasia (GTN) trials posted at online registries and aimed to provide useful information for future GTN trial designs.

STUDY DESIGN

We searched ClinicalTrials.gov, EU Clinical Trials Register, WHO International Clinical Trials Registry Portal (ICTRP) Search Portal, Australian New Zealand Clinical Trial Registry, ISRCTN Register, and Chinese Clinical Trial Register for all the clinical trials reporting GTN treatments. The general information of each trial was extracted.

RESULTS

Twenty trials meeting the inclusion criteria were included in the final analysis. In total, 6 trials were phase II trials, 2 were phase II/III trials, 7 were phase III trials, and 1 was a phase IV trial; and the phase type of 4 trials were not reported. The conditions included low-risk GTN (n = 15), high-risk GTN (n = 2), and mixed GTN (n = 3). Randomization was performed in 15 trials, and the remaining 5 trials were single-arm trials. The median enrollment size for randomized clinical trials (RCTs) and single-arm trials was 80 and 38, respectively. Among the RCTs, parallel assignment was used in 12 trials, crossover assignment was used in 1, and the intervention models of 2 were not reported. For masking, 15 trials were open-label, 2 were single-blinded, 2 were double-blinded, and the masking status of 1 was not reported. Ovarian functions and pregnancy outcome after chemotherapy were evaluated in only 2 trials. Regarding sponsorship, 2 trials had industry sponsorship.

CONCLUSION

Conducting RCTs for GTN is challenging, and international collaboration and smarter clinical trial designs are required for future GTN trials.

Hepatic toxicity following actinomycin D chemotherapy in treatment of familial gestational trophoblastic neoplasia: A case report

RATIONALE

Familial hydatidiform mole is extremely rare while familial gestational trophoblastic neoplasia (GTN) has never been reported. Inspired by 2 biological sisters with postmolar GTN and liver toxicity, we reviewed susceptible maternal-effect genes and explored the role of possible drug transporter genes in the development of GTN.

PATIENT CONCERNS

We reported one Chinese family where the two sisters developed postmolar GTN while experiencing fast remission and significant hepatic toxicity from actinomycin D chemotherapy.

DIAGNOSES

The index pregnancy was diagnosed with curettage. The following GTN was confirmed when there was a rise in beta-hCG for three consecutive weekly measurements over at least a period of 2 weeks. Computed tomography was used to identify lung metastasis. The elder sister was diagnosed with gestational trophoblastic neoplasia (III: 2) while the younger sister was diagnosed as III: 3 according to WHO scoring system.

INTERVENTIONS

Patients were treated with actinomycin D of 10 μg/kg intravenously for 5 days every 2 weeks. When hepatic toxicity was indicated, polyene phosphatidyl choline and magnesium isoglycyrrhizinate were prescribed.

OUTCOMES

Both patients responded extremely well to the 5-day actinomycin D regimen. Beta-hCG remained less than 2 mIU/ml after 5 cycles while computed tomography scan showed downsized pulmonary nodules. Both experienced significant rise in ALT and AST levels that could be ameliorated with corresponding medication. Monthly followed-up showed negative beta-hCG levels and normal liver enzyme levels.

LESSONS

We speculated that the known or unknown NLRP7 and KHDC3L mutations might be correlated with drug disposition in liver while liver drug transporters such as P-glycoprotein family that are also expressed in trophoblasts might be correlated to GTN susceptibility. Future genomic profiles of large samples alike using next generation sequencing are needed to confirm our hypothesis and discover yet unknown genes.
