ABSTRACT
OPINION STATEMENT: In addressing Gestational Trophoblastic Neoplasia (GTN), it is imperative to acknowledge the evolving landscape of treatment options, especially in light of the challenges posed by traditional methods. While historically, surgical interventions, radiation therapy, and chemotherapeutic agents have been the mainstays, the emergence of resistance and high-risk scenarios necessitates a reevaluation of our therapeutic approaches. Our review highlights the promising advancements in immunotherapy and molecular targeted therapy as viable alternatives for GTN management. The introduction of immune checkpoint inhibitors and kinase inhibitors offers a paradigm shift, particularly for patients resistant to conventional chemotherapy regimens. These novel therapies not only exhibit efficacy but also demonstrate manageable toxicity profiles, particularly in high-risk cases. However, integrating these innovative treatments into established international guidelines presents a formidable task. As we move forward, it is imperative that future research not only prioritizes fertility preservation but also rigorously evaluates long-term toxicity implications. International collaboration becomes pivotal in addressing the nuances of this rare and complex disease. In conclusion, our review underscores the need for a nuanced approach to GTN treatment, one that prioritizes reduced toxicity and improved quality of life. By embracing the advancements in immunotherapy and molecular targeted therapy, we can pave the way for more effective and patient-centered care in the management of GTN.

OBJECTIVE: Determine the cost-effectiveness for hysterectomy versus standard of care single agent chemotherapy for low-risk gestational trophoblastic neoplasia (GTN). METHODS: A cost-effectiveness analysis was conducted comparing single agent chemotherapy with hysterectomy using decision analysis and Markov modeling from a healthcare payer perspective in Canada. The base case was a 40-year-old patient with low-risk non-metastatic GTN that completed childbearing. Outcomes were life years (LYs), quality-adjusted life years (QALYs), incremental cost-effectiveness ratio (ICER), and adjusted 2022 costs (CAD). Discounting was 1.5% annually and the time horizon was the patient's lifetime. Model validation included face validity, deterministic sensitivity analyses, and scenario analysis. RESULTS: Mean costs for chemotherapy and hysterectomy arms were $34,507 and $17,363, respectively, while effectiveness measure were 30.37 QALYs and 31.04 LYs versus 30.14 QALYs and 30.82 Lys, respectively. The ICER was $74,526 (USD $54,516) per QALY. Thresholds favoring hysterectomy effectiveness were 30-day hysterectomy mortality below 0.2% and recurrence risk during surveillance above 9.2% (low-risk) and 33.4% (high-risk). Scenario analyses for Dactinomycin and Methotrexate led to similar results. Sensitivity analysis using tornado analysis found the cost to be most influenced by single agent chemotherapy cost and risk of resistance, number of weeks of chemotherapy, and probability of postoperative mortality. CONCLUSION: Compared to hysterectomy, single agent chemotherapy as a first-line treatment costs $74,526 for each additional QALY gained. Given that this cost falls below the accepted $100,000 willingness-to-pay threshold and waitlist limitations within public healthcare systems, these results support the continued use of chemotherapy as standard of care approach for low-risk GTN.

Objectives: To monitor changes in serum anti-Mullerian hormone (AMH) levels of the patients with gestational trophoblastic neoplasia (GTN) who have undergone uterine preservation during treatment with a Methotrexate (MTX) regimen and associations with AMH variations. Methods: This observational prospective cohort study included 35 patients with low-risk GTN with uterine preservation during single-agent MTX chemotherapy at Hanoi Obstetrics and Gynecology Hospital from August 2021 to August 2022. Serum AMH levels were measured before initiation of chemotherapy and after the 1st, 2nd, and 3rd chemotherapy cycles. AMH evolution and its associations with some factors were analyzed. Results: The median basal AMH level before chemotherapy was 2.87 ng/mL (0.96 - 7.9 ng/mL) and negatively correlated with age. The serum AMH levels decreased significantly after each chemotherapy cycle (2.87 vs. 1.16, 0.91, 0.41 ng/mL). The median magnitude of the AMH levels decline after 1st, 2nd, and 3rd chemotherapy cycles were 51.2%, 69.4%, and 84.6% (p<0.001), respectively. AMH variation was associated with the basal AMH level, but not with age, ßhCG at diagnosis and menstrual status. Conclusion: Our study has shown that the serum AMH levels declined rapidly and steadily in all patients during chemotherapy for GTN. Although AMH cannot be used to monitor fertility potential lonely, these new studies improve our knowledge of ovarian toxicity and ovarian reserve during chemotherapy and strongly support the use of fertility preservation strategies.

INTRODUCTION: Chemotherapy is crucial in treating gestational trophoblastic neoplasia (GTN), but its impact on gonadotoxicity is unclear. MATERIALS AND METHODS: This case-control study included 57 GTN patients and 19 age-matched patients with molar pregnancies (MP) in 2012-2018. Multiples of the median (MoM) of the serum AMH levels were compared between the two groups, and between patients using single-agent and combination chemotherapy, at baseline, 6, 12, and 24 months after treatment. Their pregnancy outcomes were also compared. RESULTS: There was no significant difference in the MoM of serum AMH between GTN and MP groups at all time points. Single-agent chemotherapy did not adversely affect the MoM. However, those receiving combination chemotherapy had lower MoM than those receiving single-agent chemotherapy at all time points. The trend of decline from the baseline was marginally significant in patients with combination chemotherapy, but the drop was only significant at 12 months (Z = -2.69, p = 0.007) but not at 24 months (Z = -1.90; p = 0.058). Multivariable analysis revealed that combination chemotherapy did not affect the MoM. There was no significant difference in the 4-year pregnancy rate and the livebirth rate between the single-agent and combination groups who attempting pregnancy, but it took 1 year longer to achieve the first pregnancy in the combination group compared to the single-agent group (2.88 vs. 1.88 years). CONCLUSION: This study showed combination chemotherapy led to a decreasing trend of MoM of serum AMH especially at 12 months after treatment, but the drop became static at 24 months. Although pregnancy is achievable, thorough counseling is still needed in this group especially those wish to achieve pregnancy 1-2 years after treatment or with other risk factors.

BACKGROUND: Multiple studies have confirmed that programmed cell death 1 (PD-1) and programmed cell death ligand 1 (PD-L1) is widely expressed in gestational trophoblastic neoplasia (GTN) tissues. Therefore, immune checkpoint inhibitors may be an option for the treatment of recurrent and drug-resistant GTN. CASE: Four patients with recurrent or drug-resistant GTN who were treated with PD-1/PD-L1 checkpoint inhibitor agents combined with chemotherapy were reported. The mean age of recurrence was 45.8 years (35-56 years), including three cases of choriocarcinoma (CC) and one case of invasive mole (IM). International Federation of Gynecology and Obstetrics (FIGO) prognosis score: ≤6 (low risk) in one case, 7-12 (high risk) in one case, ≥13 (very high risk) in two cases. There were two cases of lung metastasis and one case of vulvar and inguinal lymph node metastasis. One of the four patients underwent total hysterectomy and one patient underwent resection of lung metastases. All the four patients received comprehensive treatment of immunotherapy combined with chemotherapy after relapse, among which one patient achieved complete response (CR), two patients achieved partial response (PR), and one patient developed progressive disease (PD). Three patients who achieved PR or CR were maintained by single agent immunotherapy after combination therapy, and there was no disease recurrence during follow-up. One patient with PD also achieved CR after using salvage chemotherapy after recurrence, and there was no disease recurrence during follow-up. During the treatment, four patients had different degrees of immune-related adverse reactions, all of which were grade I-II, and no severe adverse reactions were found. CONCLUSION: Immune checkpoint inhibitors combined with chemotherapy has an impressive therapeutic effect on recurrent or drug-resistant GTN with mild adverse reactions, which can be used as a treatment option for such patients. However, due to the lack of large sample data support, the specific time and treatment course of its use, long-term use of adverse reactions and whether it affects fertility function remain to be solved.

OBJECTIVE: The treatment for high risk or recurrent gestational trophoblastic neoplasia (GTN) is a highly toxic multi-agent chemotherapy. For patients with progressive or recurrent GTN, checkpoint inhibitors have demonstrated anti-tumor activity; however, identification of novel therapies for GTN remain an unmet need. Therefore, we sought to characterize the molecular landscape of GTN to identify potential therapeutic targets. METHODS: GTN samples were analyzed using a combination of molecular - next-generation sequencing (NGS) or whole exome sequencing (WES)- and protein- Immunohistochemistry (IHC) analyses. GTN samples encompassed complete moles, choriocarcinoma, epithelioid trophoblastic tumors (ETT), and placental site trophoblastic tumors (PSTT). RESULTS: We analyzed 30 cases of GTN including 15 choriocarcinoma, 7 ETT, 5 PSTT, 1 invasive mole and 2 mixed histologies. The median age was 41.5. GTN samples were found to be PD-L1 positive (92.3%), tumor mutational burden (TMB) low (92.8%), and microsatellite stable (MSS) (100%). Forty-six percent of choriocarcinoma specimens contained a genomic alteration including TP53 (33%) and homologous recombination repair (HRR) (13%) genes. Alterations in RTK-RAS pathway signaling was present in 40% of ETT cases. CONCLUSIONS: The high rate of PD-L1 positivity in this real-world database and reported in prior literature support continued clinical trial development evaluating immunotherapy for treatment of GTN. Other potential targeted treatments identified include Wee1, PARP and MEK inhibitors based on molecular alterations in TP53, HRR genes, and RTK-RAS pathways respectively.

BACKGROUND: The standard treatment for gestational choriocarcinoma is chemotherapy. OBJECTIVE: To describe the risk of recurrence with expectant management of gestational choriocarcinoma that has reached a normal human chorionic gonadotropin level after tumor removal without adjuvant chemotherapy. METHODS: A retrospective multicenter international cohort study was conducted from 1981 to 2017 involving 11 gestational trophoblastic disease reference centers with patient's follow-up extended until 2023. Clinical and biological data of included patients were extracted from each center's database. The inclusion criteria were i) histological diagnosis of gestational choriocarcinoma in any kind of placental tissue retrieved, ii) spontaneous normalization of human chorionic gonadotropin level following choriocarcinoma retrieval, iii) patient did not receive any oncological treatment for the choriocarcinoma, iv) and at least 6 months of follow-up after the first human chorionic gonadotropin level normalization. RESULTS: Among 80 patients with retrieved gestational choriocarcinoma and whose human chorionic gonadotropin level normalized without any other oncological therapy, none had a recurrence of choriocarcinoma after a median follow-up of 50 months. The median interval between choriocarcinoma excision and human chorionic gonadotropin level normalization was 48 days. The International Federation of Gynecology and Obstetrics/World Health Organization risk score was ≤6 in 93.7% of the cases. CONCLUSIONS: This multicenter international study reports that selected patients with gestational choriocarcinoma managed in gestational trophoblastic disease reference centers did not experience any relapse when the initial tumor evacuation is followed by human chorionic gonadotropin level normalization without any additional treatment. Expectant management may be a safe approach for highly selected patients.

INTRODUCTION: Gestational trophoblastic neoplasia (GTN) is a highly invasive tumor, mainly spreading to the lungs. However, lung metastasis in GTN is usually not considered as an adverse prognostic factor. Therefore, the aim of this study was to summarize the results of previous studies and evaluate the effects of lung metastasis on the treatment and prognosis of GTN. MATERIAL AND METHODS: The study was prospectively registered in PROSPERO (CRD42023372371). Electronic databases including PubMed, Embase, the Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang, and China Biomedical Literature Database were used for a systematical search of relevant studies published up to November 21, 2022. The observational studies reporting the clinical outcomes of GTN patients with and without lung metastasis were selected. The incidences of resistance, relapse, and mortality of GTN patients were extracted and successively grouped based on the presence of lung metastasis. The pooled relative risks (RRs) and 95% confidence interval (95% CI) of the eligible studies were calculated. The qualities of included studies were assessed with the Newcastle-Ottawa Scale and the certainty of evidence was graded based on the GRADE. The meta-analysis was performed using Stata 12.0 and GradePro software. RESULTS: Five publications with 3629 GTN patients were included. The meta-analysis revealed that the GTN with lung metastasis was strongly correlated with first-line chemoresistance (pooled RR = 1.40, 95% CI: 1.22 to 1.61, p < 0.001), recurrence (pooled RR = 3.03, 95% CI: 1.21 to 7.62, p = 0.018), and disease-specific death (pooled RR = 22.11, 95% CI: 3.37 to 145.08, p = 0.001). Ethnicity was also an important factor and Caucasian GTN patients with lung metastasis showed a higher risk of recurrence as revealed by the subgroup analysis (pooled RR = 5.10, 95% CI: 2.38 to 10.94, p < 0.001). CONCLUSIONS: GTN patients with lung metastasis exhibited a higher risk of chemoresistance, relapse, and disease-specific death. Patients with lung metastasis among the Caucasian population had a higher risk of recurrence than Asian populations. Therefore, the presence of lung metastases might be considered as a high-risk factor for prognosis of GTN and deserves more attention in the choice of first-line chemotherapy regimens and follow-up.

INTRODUCTION: Gestational trophoblastic neoplasia (GTN) with intracardiac metastasis is rare, and here we reported a patient with intracardiac metastasis of high-risk and refractory gestational choriocarcinoma and reviewed relevant literatures. CASE PRESENTATION: A 37-year-old woman presented with vaginal bleeding and high level of ß-human chorionic gonadotropin (ß-hCG) at 199,060 (mIU/mL). It was clinically diagnosed with gestational choriocarcinoma. The patient initially received eight cycles of chemotherapy but unsatisfactory response was observed, and the level of ß-hCG still ranged between 5000 and 10,000. Then there was found intracardiac masses in the right atrium (2.6*1.7 cm), anterior chordae tendineae of the tricuspid valve (1.4*0.7 cm) and the right ventricle (4.1*2.9 cm) by ultrasonic cardiogram (UCG). PET/CT highly suspected the intracardiac metastasis of choriocarcinoma (SUVmax = 9.3) and no disease was found in the lung and pelvis. The patient undertook complete intracardiac masses resection. The pathology confirmed the intracardiac metastasis of disease. After a week of operation, the UCG found a 5.4*4.2 cm mass in the right atrium again. Considering the poor prognosis, the patient received palliative care and eventually died of disease progression. CONCLUSION: Intracardiac metastasis of GTN is an aggressive sign of disease. Patients can benefit from chemotherapy and surgery. Future investigation of PD-1 immunotherapy combines with chemotherapy are expected to improve the prognosis in this group of patients.

OBJECTIVE: To investigate the clinicopathological features, prognostic factors, treatment, clinical response, and outcome of gestational choriocarcinoma (GCC). MATERIALS AND METHODS: A retrospective review was made of the clinicopathological and survival data of 13 patients who were diagnosed and treated for GCC in two referral centers in Turkey between 1992 and 2020. RESULTS: The median age of patients was 36 years (range, 27-54 years), and seven were ≤39 years. The antecedent pregnancy was a term in nine (69.2%) cases, and the risk score was ≥7 in 11 (84.6%). According to the International Federation of Gynecology and Obstetrics 2009 staging, eight cases were in stage I, two in stage III, and three in stage IV. With the exception of one patient, all the others received combination chemotherapy (CT), and two of those were also treated with radiotherapy. Chemoresistance developed in 50% (6/12), and second-line CT was given to four of these. The overall complete response rate was 69.2%. Four patients died of chemoresistance and disease progression, all of them were with antecedent-term pregnancy, had high scores ≥7, and had metastases. CONCLUSION: GCC is a unique subtype of gestational trophoblastic neoplasia, which differs from others in terms of poor prognosis, a frequent tendency to early metastasis, and resistance to treatment. To be able to achieve the most efficient therapy and prognosis, histopathology-based risk models should be developed.

BACKGROUND: Chemotherapy is the recommended treatment for gestational trophoblastic neoplasia (GTN). Second curettage had been advocated to avoid unnecessary chemotherapy and to reduce the courses of chemotherapy; however, consensus has not been reached as there are arguments claiming its inability of inducing complete regression. OBJECTIVES: The present study was performed to clarify the effectiveness of second curettage for avoiding unnecessary chemotherapy and lowering the number of chemotherapy courses in patients with post-molar GTN. SEARCH STRATEGY: Seven predominant electronic databases were searched, including four English databases and three Chinese databases, from the inception of each database until January 31, 2023. SELECTION CRITERIA: Studies were included if they were: (1) human, (2) explicitly indicated exposure to second curettage, (3) explicitly indicated control to conventional chemotherapy, (4) explicitly indicated the participants were patients with gestational trophoblastic neoplasia (GTN), and (5) compared the outcome of interest as the number of the course of chemotherapy. DATA COLLECTION AND ANALYSIS: Two authors extracted and analyzed the data independently. Disagreements were reconciled by reviewing the full text by a third author. The data of study location, data collection, study design, number of participants, intervention strategy, control strategy, the follow-up period, outcome, adverse events were analyzed. MAIN RESULTS: With regard to avoiding unnecessary chemotherapy, the overall pooled effect size of the second curettage group had a significant advantage over the conventional chemotherapy group with an OR of 0.02 (95% CI: 0.00-0.06). Meanwhile, for reducing the number of chemotherapy courses, the overall pooled effect size of the second curettage group had significant advantage over the conventional chemotherapy group with a mean difference of -2.11 (95% CI: -3.72 to -0.51). CONCLUSION: The second curettage group had a significant advantage over the conventional chemotherapy group in avoiding unnecessary chemotherapy and reducing the number of chemotherapy courses. Further larger multi-center randomized controlled trials should be conducted to confirm our results and to clarify the optimal patients' group for second curettage in patients with post-molar GTN.

PURPOSE: The efficacy of immune checkpoint blockade in gestational trophoblastic neoplasia (GTN) remains uncertain. We report the results of the GTN cohort of SWOG S1609 dual anti-CTLA-4 and anti-PD-1 blockade in rare tumors (DART). PATIENTS AND METHODS: This prospective, open-label phase II trial evaluated ipilimumab plus nivolumab across multiple rare tumor cohorts, including GTN. Eligible patients received nivolumab 240 mg, i.v. every 2 weeks and ipilimumab 1 mg/kg i.v. every 6 weeks. The primary endpoint was overall response rate [ORR; complete response (CR) + partial response (PR)] by quantitative serum beta human chorionic gonadotropin (ß-hCG); secondary endpoints included progression-free survival (PFS), overall survival (OS), and toxicity. RESULTS: Four patients with refractory GTN enrolled and received therapy. At 11 months of ongoing follow-up, 3 of 4 patients responded [ORR = 75% (CR, 25%, n = 1, tumor mutation burden = 1 mutation/megabase; PD-L1 tumor proportion score = 50%); PR, 50%, n = 2)]. Responders included malignant gestational trophoblastic neoplasm (n = 1, CR, PFS 11+ months) and choriocarcinoma (n = 2, both PRs, PFS 10+ and 6+ months). One patient with epithelioid trophoblastic tumor experienced disease progression. The 6-month PFS was 75% [95% confidence interval (CI), 43%-100%], and the median PFS was not reached (range, 35-339+ days); all 4 patients were alive at last follow-up. Two patients experienced grade 3 immune-related toxicity (arthralgia and colitis); there were no grade ≥4 events. CONCLUSIONS: Ipilimumab plus nivolumab demonstrated efficacy in chemotherapy-refractory GTN, an ultra-rare cancer affecting young women. Three of 4 patients achieved ongoing objective responses with a reasonable safety profile at 6-11+ months.

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.

OBJECTIVE: The International Federation of Gynecology and Obstetrics (FIGO) scoring system uses the sum of eight risk-factors to predict single-agent chemotherapy resistance in Gestational Trophoblastic Neoplasia (GTN). To improve ease of use, this study aimed to generate: (i) streamlined models that match FIGO performance and; (ii) visual-decision aids (nomograms) for guiding management. METHODS: Using training (n = 4191) and validation datasets (n = 144) of GTN patients from two UK specialist centres, logistic regression analysis generated two-factor models for cross-validation and exploration. Performance was assessed using true and false positive rate, positive and negative predictive values, Bland-Altman calibration plots, receiver operating characteristic (ROC) curves, decision-curve analysis (DCA) and contingency tables. Nomograms were developed from estimated model parameters and performance cross-checked upon the training and validation dataset. RESULTS: Three streamlined, two-factor models were selected for analysis: (i) M1, pre-treatment hCG + history of failed chemotherapy; (ii) M2, pre-treatment hCG + site of metastases and; (iii) M3, pre-treatment hCG + number of metastases. Using both training and validation datasets, these models showed no evidence of significant discordance from FIGO (McNemar's test p > 0.78) or across a range of performance parameters. This behaviour was maintained when applying algorithms simulating the logic of the nomograms. CONCLUSIONS: Our streamlined models could be used to assess GTN patients and replace FIGO, statistically matching performance. Given the importance of imaging parameters in guiding treatment, M2 and M3 are favoured for ongoing validation. In resource-poor countries, where access to specialist centres is problematic, M1 could be pragmatically implemented. Further prospective validation on a larger cohort is recommended.

OBJECTIVE: To assess the HIV prevalence in patients diagnosed with gestational trophoblastic neoplasia (GTN). DESIGN: A retrospective single centre cohort study. METHODS: A database from the Sheffield Trophoblastic Disease Centre (STDC), Sheffield, UK was searched between 1st January 2015 and 31st December 2021. A total of 3,591 patients were referred to STDC with a diagnosis of gestational trophoblastic disease (GTD), of which 221 (6.2%) were treated for GTN. The prevalence of HIV-positive tests in GTN patients was assessed. RESULTS: HIV testing was performed in 93% GTN patients ( n â=â205/221). Overall, 1.3% of GTN patients ( n â=â3/221) were HIV-positive, involving two known HIV-positive patients and one new diagnosis. This equates to a HIV prevalence of 14â:â1000, which is â¼7 to 9× higher than the HIV prevalence in Sheffield (1.9 per 1000) and Yorkshire and Humber (1.5 per 1000). CONCLUSION: Given the extremely high HIV prevalence in our population, 'opt out' HIV testing is recommended within our specialist trophoblastic centre for all referred GTD and GTN patients. There is little reason to suspect that the prevalence of HIV-positive patients is any lower in the cohort of GTD patients referred to specialist trophoblastic centres for hCG screening alone, without requiring chemotherapy, particularly considering that most GTN arises from GTD.

BACKGROUND Gestational choriocarcinoma (GC) is an uncommon neoplasia that occurs in women who may not have completed a procreation plan. The aim of this study was to evaluate oncological and obstetrical outcomes in young patients with GC after fertility-sparing treatment. MATERIAL AND METHODS The eligibility criteria for the study were histopathological diagnosis of GC, age ≤40 years, and treatment with systemic chemotherapy. Patients who underwent upfront hysterectomy were excluded. The response to treatment was assessed according to beta-human chorionic gonadotropin (beta-hCG) serum measurement. Complete response and progression were considered if the beta-hCG dropped to a normal range and increased (or reached a plateau), respectively. The birth rate was calculated as the number of women who gave birth after treatment divided by the total number of patients. RESULTS A total of 18 patients fulfilled the study's eligibility criteria. A complete response and progression to first-line chemotherapy were found in 13 (72.22%) and 5 (27.78%) patients, respectively. Salvage treatment was administered to patients with progression. Overall, 16 (88.88%) patients achieved complete response after treatment and 2 (11.12%) died. GC relapse was diagnosed in 1 patient 62 months after treatment. The birth rate was 22.22%, and a total of 6 children were born. All pregnancies ended in term delivery. No congenital abnormalities were detected in the newborns. CONCLUSIONS GC is a life-threatening form of gestational trophoblastic neoplasia, mainly due to its rapid course and resistance to chemotherapy. Most patients with GC will not be able to bear children after treatment.

BACKGROUND: Gestational Trophoblastic Neoplasia (GTN) is a disease of the reproductive age group with an incidence rate of <1% among all tumors involving the female reproductive tract. It occurs because of aberrant fertilization. Patients are diagnosed early because of aggravated symptoms during pregnancy. Moreover, patients also bleed from the tumor sites, which leads to early presentation. A cure rate of 100% can be achieved with adequate treatment. MAIN BODY: In this literature review, the authors have brought to attention the risk factors, classification, and various treatment options in GTN patients according to their stratification as per the WHO scoring system. Patients are categorized into low and high risk based on the FIGO scoring system. Patients with low risk are treated with single-agent methotrexate or actinomycin-D. Despite the superiority of actinomycin-D in terms of efficacy, methotrexate remains the first choice of therapy in low-risk patients due to its better toxicity profile. Multi-agent chemotherapy with etoposide, methotrexate, actinomycin-D, cyclophosphamide and vincristine (EMA-CO) leads to complete remission in 93% of high-risk GTN patients. Around 40% of patients with incomplete responses are salvaged with platinum-based multi-agent chemotherapy. Isolated chemo-resistant clones can be salvaged with surgical interventions. CONCLUSION: The mortality in patients with GTN has significantly reduced over time. With adequate multi-disciplinary support, patients with GTN can ultimately be cured and can spend every day healthy reproductive life.

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.
