Abstract
RATIONALE Epithelioid trophoblastic tumor (ETT) is an extremely rare variant of gestational trophoblastic neoplasms (GTNs). The biological behavior and therapeutic schedule of ETT remains to be defined which frequently poses diagnostic and therapeutic challenges. Although ETT is a relatively indolent malignancy tumor, the therapeutic efficacy and survival rate decrease significantly when presented with metastases. The lung is the most common site of ETT metastasis. PATIENT CONCERNS A 39-year-old female patient presented with irregular vaginal bleeding and slight distention pain in lower abdomen. DIAGNOSES The patient was diagnosed ETT with lung metastasis after surgery and immunohistochemical staining. INTERVENTIONS A total abdominal hysterectomy plus bilateral salpingectomy and histopathology were performed. The patient received 3 cycles of etoposide, methotrexate, actinomycin-D/etoposide, cisplatin (EMA/EP) regimen chemotherapy after surgery. Due to the presence of lung metastasis, she received pulmonary lesion resection and another cycle of postoperative chemotherapy. OUTCOMES The patients showed a good response to treatment initially. However, the patient did not complete the full initial treatment for family reasons and had signs of recurrence after 2.5 months. The serum β-hCG level gradually elevated and the lung imaging showed that the lesion area gradually expanded. After 15 months of follow-up, the patient declined further treatment due to a lack of presenting symptoms. LESSONS The diagnosis of ETT should be taken into consideration in patients with abnormal vaginal bleeding and low levels of β-hCG. Patients with metastatic disease should be treated with complete surgical resection and intensive combination chemotherapy to maximize the opportunity for cure. Targeted biological agents might be potential therapeutic strategies for chemotherapy-resistant or recurrent patients.

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

Abstract
Background There is no consensus for the management of epithelioid trophoblastic tumor (ETT) up to date. Objective ETT is the rarest form of gestational trophoblastic neplasia (GTN). Our goal was to assess the outcomes and explore the prognostic factors of patients with ETT through this multicenter retrospective analysis and to devise a risk-adapted approach to clinical management. Methods A total of 31 patients were validated as ETT pathologically between January 2004 and June 2021 from three tertiary hospitals. We retrospectively analyzed the characteristics, treatments, outcomes, and prognostic factors. Results Eight patients experienced a recurrence, and 6 patients died of ETT, resulting in a mortality rate of 19.4%. Five patients with stage I disease had a fertility-preserving treatment. Among them, one patient had a full-term delivery, whereas a 23-year-old patient who declined a hysterectomy died of a recurrent disease. Eight patients of extrauterine ETT with isolated pulmonary lesion were at a young age at diagnosis (median: 30.5 vs. 41, p = 0.003) and had a smaller tumor size (median: 2.4 vs. 4.8 cm, p = 0.003) compared with other patients who had a metastatic disease, and none of them died. The multivariate analyses showed that the number of metastases ≥3 [hazard ratio (HR), 28.16, p = 0.003] was the only significant predictor associated with adverse overall survival, while the number of metastases ≥3 (HR 9.59, p = 0.005) and chemotherapy alone (HR 16.42, p = 0.001) were associated with adverse recurrence-free survival. Patients in stage I or with number of metastases <3 had a favorable prognosis, whereas the prognosis of patients whose number of metastases ≥3 remains poor. Conclusions Chemotherapy alone is insufficient for patients with ETT. Surgical procedures are the mainstay of management for ETT patients. Combined surgery and multi-agent chemotherapy are recommended for patients with metastatic disease and localized disease with persistently positive human chorionic gonadotrophin levels after surgery. The number of metastases at ≥3 is the most critical risk factor for ETT.

Abstract
Epithelioid trophoblastic tumours are rare neoplasms showing differentiation towards the chorion leave-type intermediate cytotrophoblast, with only a handful of cases being reported in the literature. These tumours are slow-growing and are typically confined to the uterus for extended periods of time. While the pathogenesis is unclear, they are thought to arise from a remnant intermediate trophoblast originating from prior normal pregnancies or, less frequently, gestational trophoblastic tumours. A protracted time period between the gestational event and tumour development is typical. This case describes a 49-year-old previously healthy female who presented with a completely asymptomatic uterine mass, discovered incidentally during a routine gynaecological assessment. The pathological analysis of the hysterectomy specimen confirmed an epithelioid trophoblastic tumour, involving the uterus and cervix. This is a rare gynaecological tumour. A comparative short tandem repeat analysis revealed genetic similarities to a previous healthy gestation seventeen years prior. She was successful treated with adjuvant pembrolizumab, with no evidence of disease recurrence to date.

Abstract
ETT is a rare variant of GTN that is more chemoresistant than choriocarcinoma. Approximately 25–35% of patients with ETT present with metastatic disease. Chemotherapy for ETT should consist of an etoposide/platinum-based regimen. Multimodality treatment can result in successful management of stage IV ETT.
Epithelioid trophoblastic tumor (ETT) is a rare variant of gestational trophoblastic neoplasia (GTN) that develops from chorionic-type intermediate trophoblast, is more resistant to chemotherapy than choriocarcinoma, and presents with metastatic disease in 25–35% of cases. We report a case of a 32-year-old who presented one week postpartum with severe abdominal pain and was found to have profound anemia and an elevated hCG level. CT scans and MRI revealed bleeding from hepatic masses, multiple hemorrhagic pulmonary nodules, a 7 cm uterine mass, and brain metastases. She underwent emergent hepatic embolization, was started on induction chemotherapy with weekly low-dose etoposide and cisplatin followed by a transition to etoposide, high-dose methotrexate, actinomycin D, etoposide, and cisplatin (HD EMA-EP), received stereotactic brain radiotherapy, and subsequently underwent minimally-invasive hysterectomy. She remains disease free over one year after the completion of treatment. An aggressive multimodal treatment approach employing etoposide/cisplatin-based chemotherapy as well as surgical procedures to control hemorrhage or excise resistant disease, and radiotherapy for brain metastases can result in successful treatment of stage IV ETT.

Abstract
Gestational trophoblastic diseases are a group of pregnancy-related disorders, originated from trophoblast cells. They include benign and aggressive tumors, such as the invasive mole, the choriocarcinoma, the placental site trophoblastic tumor (PSTT), and the epithelioid trophoblastic tumor (ETT). These malignancies are characterized as gestational trophoblastic neoplasm (GTN), rarer, although more dangerous. The diagnosis of GTN is made in most cases by monitoring serum chorionic gonadotropin (hCG) with histological confirmation. The use of specific tissue biomarkers has been increasingly employed as a differential diagnosis, leading to more accurate results and different therapy protocols and prognosis for each GTN. The treatment is based on the International Federation of Gynecology and Obstetrics anatomical staging system and the World Health Organization prognostic score system. If an accurate diagnosis is made and the guidelines followed, the cure for choriocarcinoma and invasive mole cases can reach 98%, whereas PSTT and ETT still present mild success rates. The improved knowledge about GTN and its peculiarities allows physicians to efficiently achieve the differential diagnosis and choose the best available therapy protocol, thus increasing the overall survival of affected women. Nevertheless, obtaining epidemiological data and improving knowledge through basic and translational research are essential to answer open questions on GTN physiopathology, their causes, and cellular behavior.

Abstract
Gestational trophoblastic neoplasia (GTN), a subset of gestational trophoblastic disease (GTD), occurs when tumors develop in the cells that would normally form the placenta during pregnancy. 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, high-risk GTN, and intermediate trophoblastic tumor.

Abstract
BACKGROUND Epithelioid trophoblastic tumor (ETT) derived from intermediate trophoblasts is one type of gestational trophoblastic neoplasia (GTN), and it accounts for less than 2% of all gestational trophoblastic diseases (GTD). Extrauterine ETT is extremely rare, and there is currently no consistent strategy for its treatment and management. Therefore, the aim of the study is to analyze and summarize the clinicopathologic features of extrauterine ETT with or without metastasis. METHOD The Web of Knowledge, Google Scholar, EMbase, congress of library, and PubMed were searched for extrauterine ETT without primary uterine lesions. All available data were extracted from published case reports or serial case reports, and then, the clinical and pathological characteristics were analyzed. RESULTS Twenty-two clinical studies consisting of 27 patients diagnosed with extrauterine ETT, according to the given inclusion and exclusion criteria, were included in the study. A total of 27 cases of extrauterine ETT were identified. Of these cases, four (14.81%) were located in the lungs, three (11.11%) in the ovaries, two (7.41%) in the vagina, and eight (29.63%) patients had other primary lesions. The patients originated from different continents, with 59% located in Asia and 26% in North America. Among 23 patients, the antecedent pregnancy prior to the diagnosis was full-term in 12 cases, abortion in 6 cases, hydatidiform mole in 3 cases, and invasive mole in 1 case. From the available antecedent information on pregnancy, the median interval from pregnancy to diagnosis of extrauterine ETT was 4 years. Additionally, the median gravidity and para of the patients was three times and two times, respectively. The median hCG titer was 14,374 mIU/mL in 5 patients, and the mean β-HCG titer was 3,724,805 mIU/mL in 14 patients. For all patients, the disease was confined to extrauterine ETT at diagnosis. From the available information, 20 cases were successfully treated by extraction of local lesions, and 12 cases received chemotherapy. Diagnosis was confirmed by histological tests. The Ki-67 staining ranged from 8.7 to 80%, and tumors were positive for hCG, PLAP, EMA, and p63. CONCLUSION In this study, we observed that abnormal levels of serum hCG titers and the local presentation of lesions with varying intervals after antecedent term pregnancy were the most common presenting features of extrauterine ETT. In addition, we found that the extraction of extrauterine lesions was needed for the treatment of extrauterine ETT. Of course, the follow-up was also important.

Abstract
Placental site trophoblastic tumor [PSTT] and epithelioid trophoblastic tumor [ETT] are the rarest gestational trophoblastic neoplasias, developing from intermediate trophoblast of the implantation site and chorion leave, respectively. PSTT and ETT share some clinical-pathological features, such as slow growth rates, early stage at presentation, relatively low βhCG levels and poor response to chemotherapy. The mortality rate ranges from 6.5% to 27% for PSTT and from 10% to 24.2% for ETT. Advanced stage, long interval between antecedent pregnancy and diagnosis, and presence of clear cells are the independent prognostic variables for PSTT, and they may be similar for ETT. Hysterectomy can represent the only therapy for early disease, whereas adjuvant chemotherapy should be reserved to patients with poor risk factors, such as an interval from the antecedent pregnancy >4 years, deep myometrial invasion or serosal involvement. Few cases of fertility-sparing treatment in young women have been reported. An individualized multidisciplinary approach, including chemotherapy and debulking surgery with abdominal and/or extra-abdominal procedures, is warranted for advanced disease. EP/EMA and TP/TE are the preferred regimens in this setting. Immunohistochemistry has sometimes shown expression of EGFR, VEGF, MAPK, PDGF-R and PD-L1, and therefore investigational studies on biological agents targeting these molecules are strongly warranted for chemotherapy resistant-disease.

Abstract
Background: Epithelioid trophoblastic tumors (ETTs) are the rarest type of gestational trophoblastic neoplasias. We investigated the clinical features, treatments, outcomes, and prognostic factors in patients with ETT, and explored potential therapeutic targets. Methods: We retrospectively analyzed the clinical features, treatments, survival, and prognostic factors of 21 ETT patients treated at our institution between January 2002 and December 2017. Expression levels of programmed cell death 1 (PD-1), PD-1 ligands (PD-L1and PD-L2), B7 family ligands (B7-H3, B7-H4, V-domain Ig suppressor of T cell activation [VISTA], and B7-H6), and CD105 expression were assessed by immunohistochemistry. Results: Fourteen patients with ETT (66.7%) presented with irregular vaginal bleeding. Three stage I patients (14.3%) with normal β-human chorionic gonadotropin (β- hCG) levels underwent hysterectomy alone. Of the remaining 18 patients who had elevated β-hCG levels (85.7%), 1 received chemotherapy and 17 underwent surgery and multi-agent chemotherapy. After treatment, 17 patients (81.0%) achieved complete remission (2 of whom [11.8%] later relapsed) and 4 (19.0%) with stage IV died of their disease. On univariate and multivariate analyses, stage IV disease was an independent prognostic factor for overall and disease-free survival (P < 0.001). PD-L1, B7-H3, and CD105 were detected in 100% of samples, PD-L2 and VISTA in 82%, B7-H6 in 18%, and B7-H4 was undetectable in ETT cells. Conclusions: Hysterectomy and metastatic lesion resection are essential for controlling ETT. Surgery plus chemotherapy are recommended for patients with abnormal β-hCG levels and metastatic disease. PD-L1, PD-L2, B7-H3, VISTA and CD105 are potential therapeutic targets for metastatic ETT.

Abstract
OBJECTIVE Epithelioid Trophoblastic Tumor (ETT) is an extremely rare form of Gestational Trophoblastic Neoplasia (GTN). Knowledge on prognostic factors and optimal management is limited. We identified prognostic factors, optimal treatment, and outcome from the world's largest case series of patients with ETT. METHODS Patients were selected from the international Placental Site Trophoblastic Tumor (PSTT) and ETT database. Fifty-four patients diagnosed with ETT or mixed PSTT/ETT between 2001 and 2016 were included. Cox regression analysis was used to identify prognostic factors for overall survival (OS). RESULTS Forty-five patients with ETT and 9 patients with PSTT/ETT were included. Thirty-six patients had FIGO stage I and 18 had stages II-IV disease. Patients were treated with surgery (n = 23), chemotherapy (n = 6), or a combination of surgery and chemotherapy (n = 25). In total, 39 patients survived, including 22 patients with complete sustained hCG remission for at least 1 year. Patients treated with surgery as first line treatment had early-stage disease and all survived. Most patients treated with chemotherapy with or without surgery had FIGO stages II-IV disease (55%). They underwent multiple lines of chemotherapy. Eleven of them did not survive. Interval since antecedent pregnancy and FIGO stage were prognostic factors of OS (p = 0.012; p = 0.023 respectively). CONCLUSIONS Advanced-stage disease and an interval of ≥48 months since the antecedent pregnancy are poor prognostic factors of ETT. Surgery seems adequate for early-stage disease with a shorter interval. Advanced-stage disease requires a combination of treatment modalities. Because of its rarity, ETT should be treated in a centre with experience in GTN.
