Embolization for hemorrhage of liver metastases from choriocarcinoma

Treatment of High-Risk Gestational Trophoblastic Neoplasia

High-risk gestational trophoblastic neoplasia encompasses patients with high volumes of disease or diffuse metastatic involvement who are unlikely to achieve remission with single-agent chemotherapy. Etoposide-based multi-drug regimens form the core of high-risk therapy. Second-line therapy includes platinum-based regimens. Increasingly, third-line therapy uses immunotherapy. Surgical intervention may be required to resect foci of resistant disease or manage complications. Treatment should continue until the hCG is less that the reference range for normal, followed by at least 3 cycles of consolidation therapy. At least 2 years of hCG surveillance are advisable for most patients requiring multiagent therapy to encompass 95% of relapses.

Surgical Management of Gestational Trophoblastic Disease

BACKGROUND

Gestational trophoblastic disease (GTD) is a rare pregnancy-related condition consisting of premalignant and malignant forms arising from proliferation of trophoblastic cells. The malignant forms are collectively referred to as gestational trophoblastic neoplasia (GTN) and are highly sensitive to chemotherapy. However, surgical procedures remain indispensable in the diagnosis and treatment of GTD.

OBJECTIVES

The aim of this review was to summarize surgical interventions in the treatment of GTD and GTN. We reviewed indications, efficacy, possible complications, and oncological outcomes of surgery.

METHODS

Three searches were performed in the databases of PubMed, Embase, and the Cochrane Library to create an up-to-date overview of existing literature on the following subjects: (1) the role of primary hysterectomy in GTD and GTN; (2) the role of second curettage in GTD and GTN; (3) fertility sparing surgery in GTN; (4) surgical management of metastases. Included articles originated from the time period 1952-2022. Articles written in English, Spanish, and French were included.

OUTCOMES

Thirty-eight articles were found and selected. Surgical evacuation through suction curettage is most used and advised in the treatment of GTD. A second curettage could be beneficial in patients with low hCG levels and low FIGO scores. In women who have completed their families, primary hysterectomy might be considered as the risk of subsequent GTN is lower than after suction curettage. In case of the rare forms of GTN (epithelioid trophoblastic tumor or placental site trophoblastic tumor) surgical tumor resection remains the most important step in treatment. Data on fertility sparing surgery in GTN are scarce and this treatment should be considered experimental.

CONCLUSION AND OUTLOOK

Surgery remains an important part of treatment of GTD and is sometimes indispensable to achieve curation. Further collection of evidence is needed to determine treatment steps.

Choriocarcinoma complicated with intra-abdominal and intrapleural hemorrhage in pregnancy - case report

Background

Choriocarcinoma is a rare neoplasm, exceptionally uncommon during an ongoing pregnancy. The disease often has a metastatic character, causing severe symptoms from various anatomic sites like the lungs, central nervous system, vagina, pelvis, or liver. Due to the condition's rarity, evidence on how to treat the choriocarcinoma originating during pregnancy remains scarce.

Case presentation

Here, we present a case of a patient who developed choriocarcinoma before the 29th week of gestation. The neoplasm had a metastatic character, resulting in hemorrhage complicated by a hypovolemic shock. The patient underwent an emergency cesarean section and several surgeries to stop the massive hemorrhage. The treatment of the choriocarcinoma included chemotherapy with methotrexate followed by an EMA-CO regimen. The patient had a complete response to the therapy. The neonate suffered from complications related to prematurity.

Conclusion

Metastatic choriocarcinoma can be a diagnostic and therapeutic challenge during ongoing pregnancy. Treatment of the disease can be associated with severe complications, but a complete response to chemotherapy is possible with a favorable long-term prognosis.

Spontaneous rupture of a retroperitoneal lymph node metastasis causing massive hemorrhage in a patient with advanced mixed germ cell tumor

Retroperitoneal hemorrhage is a rare and life-threatening clinical presentation that may occur in patients with advanced germ cell tumors, typically after chemotherapy. Rapid clinical suspicion is crucial to offer the best treatment. Surgery is usually recommended but dismal complications may occur. We report on a man with metastatic testicular cancer presenting with massive spontaneous retroperitoneal hemorrhage that had not received previous systemic treatment and was managed without surgical treatment, with good clinical outcome.

Treatment of high-risk gestational trophoblastic neoplasia and chemoresistance/relapsed disease

High-risk gestational trophoblastic neoplasia (GTN) has an increased risk of developing chemoresistance to single-agent chemotherapy; therefore, the primary treatment should be a multiagent etoposide-based regimen, preferably EMA/CO. After remission (normalization of human chorionic gonadotropin - hCG), at least three consolidation courses of EMA-CO are needed to reduce the risk of relapse. Chemoresistance is diagnosed during treatment if hCG levels plateau/increase, in two consecutive values over a two-week period. When this occurs after remission, in the absence of a new pregnancy, there is a relapse. In both cases, after re-assessment of the extent of disease, EMA-EP is the most common chemotherapy choice. Even in these cases, remission rates are high. After remission is achieved, hCG should be measured monthly for a year. Pregnancy can be allowed after 12 months from remission. The follow-up of these patients in referral centers minimizes the chance of death from this disease and should be encouraged.

Surgical Management of Gynecologic Cancers

This article addresses the role of surgery in the management of gynecologic cancers with liver metastases. The authors review the short-term and long-term outcomes of aggressive resection through retrospective and randomized studies. Although the data supporting aggressive resection of liver metastasis are largely retrospective and case based, the randomized control data to address neoadjuvant versus chemotherapy have been widely criticized. Residual disease remains an important predictor for survival in ovarian cancer. If a patient cannot achieve near optimal cytoreduction, radical cytoreductive procedures, such as hepatic resection, should be considered for palliation only.

Clinical presentation and diagnosis of Gestational Trophoblastic Disease

Gestational trophoblastic disease (GTD) is a heterogeneous group of pregnancy-related disorders characterized by abnormal proliferation of trophoblastic tissue. It encompasses the premalignant partial and complete hydatidiform mole but also the malignant invasive mole, choriocarcinoma, placental-site trophoblastic tumor, and epithelioid trophoblastic tumor. The clinical presentation changed to earlier detection after the introduction of first trimester ultrasounds. Patients are often asymptomatic, but vaginal bleeding continues to be the most common presenting symptom. Other symptoms can develop in the case of metastatic disease. Ultrasound, serum human chorionic gonadotrophin, and sometimes additional imaging such as CT, MRI, or PET can confirm the diagnosis and stage of disease. Familiarity with the pathogenesis, classification, imaging features, and treatment of GTD facilitates diagnosis and appropriate management.

Successful treatment of multisite hemorrhage by several methods in brain metastasis of choriocarcinoma: A case report

RATIONALE

Brain metastasis of choriocarcinoma is a highly malignant gestational trophoblastic neoplasia (GTN) and has a notoriously poor prognosis. Hemorrhagic choriocarcinoma lesions may lead to life-threatening conditions also. Treatment of brain metastases of choriocarcinoma with hemorrhage in multiple sites is very difficult in clinical practices. A patient has been successfully treated in our hospital, which provides as clinical references for this difficulty in treating brain metastases of choriocarcinoma with hemorrhage in multiple sites.

PATIENT CONCERNS

A 28-year-old patient with gravida 2, para 0 was admitted in our hospital for amenorrhea, vaginal bleeding, and lower abdominal pain.

DIAGNOSES

The patient was diagnosed as choriocarcinoma FIGO stage IV and the score of the Prognostic Scoring Index modified by the WHO was 15.

INTERVENTIONS

The patient received multiagent chemotherapy (EMACO regimen) soon after the diagnosis of choriocarcinoma with brain metastasis. During the therapy, the patient was given 3 different methods of treatment for metastatic site hemorrhage. An emergency surgery was performed to control massive bleeding from the metastatic lesions of broad ligament. Blood transfusions were given to treat acute left pulmonary hemorrhage. Uterine artery embolization (UAE) was performed to treat increased uterine bleeding.

OUTCOMES

The patient achieved remission after 9 cycles of chemotherapy. She has been followed up for 14 months with no signs of tumor recurrence.

LESSONS

The diagnosis of choriocarcinoma may be difficult, especially in the setting with the limit of medical resources. The application of various diagnostic techniques such as x-ray, computed tomography, and magnetic resonance imaging is helpful for evaluating the patient's condition.

Pancreatic and Hepatic Metastasis of an Undiagnosed Choriocarcinoma: An Exceptional Cause of Haemoperitoneum in Young Women - Report of a Rare Case

Haemoperitoneum in women of reproductive age usually suggests either ruptured ectopic pregnancy or ruptured ovarian cysts. Metastatic choriocarcinoma is considered the least common cause of haemoperitoneum in women of childbearing age. We report a rare case of pancreatic and hepatic metastasis of choriocarcinoma in a young, 30-year-old female who had delivered 10 months prior at term gestation with no previous history of gestational trophoblastic disease or molar pregnancy. She had a short history of fever and pain in the right hypochondrium, with findings of hypovolaemic shock due to intraperitoneal haemorrhage. Unfortunately, the patient expired with massive uncontrolled bleeding from liver metastasis despite 2 emergency laparotomies within 12 h. This case report is an apt reminder to clinicians to include metastatic choriocarcinoma on the list of differential diagnoses for haemoperitoneum with a positive pregnancy test in women of reproductive age to diagnose early and to avoid life-threatening consequences.

Arteriovenous Fistula Embolization in Suspected Parauterine Choriocarcinoma

This is a case of choriocarcinoma that did not regress after chemotherapy treatment. A 30-year-old female patient (gravida 2, para 2), presented to our ER with stroke and persistent mild pelvic pain 2 months after a Caesarean section. Computed tomography (CT) revealed an ischemic left hemicerebellar region and a hypervascular mass in the pelvic region. This mass was not present on routine fetal ultrasound during pregnancy. The lesion was treated by chemotherapy after closure of a foramen ovale and insertion of an inferior vena cava (IVC) filter. After that, 2 courses of EMACO (Etoposide, Methotrexate, Actinomycin D, Cyclophosphamide, and Vincristine) chemotherapy regimen were given. Posttreatment CT showed the hypervascular mass without any changes. Arteriography showed the arteriovenous fistulae that were embolized successfully with plugs, coils, and glue. Embolization was considered due to the risk of acute hemorrhagic life-threatening complications. Eight chemotherapy courses were added after embolization. Treatment by endovascular approach and reduction of the hypervascular mass can be a valuable adjunct to chemotherapy treatment of choriocarcinoma.

Amyloidosis and spontaneous hepatic bleeding, transcatheter therapy for hepatic parenchymal bleeding with massive intraperitoneal hemorrhage: a case report and review of the literature

Hepatic hemorrhage can be devastating, especially in patients with underlying hepatic pathology. This is a case report of a 50-year-old man who presented to the emergency room with Stage 3 shock as evidenced by a systolic blood pressure of 90 mmHg, a heart rate of 125 beats per minute, respiration of 32, with delayed capillary refill and agitation. At this time, he was found to have a massive spontaneous intra-abdominal hemorrhage with an advanced stage of amyloidosis with multiple organ malfunctions. The initial diagnosis was based on an abdominal computed tomography scan and the patient was taken expeditiously to a hybrid angiography suite for a celiac angiogram. An intraoperative diagnosis of extravasation from amyloid related vasculopathy was made based on the angiographic appearance of hepatic circulation. Coil embolization of the feeding branch of the bleeder was achieved using the interlock coil system and a completion angiogram was done showing complete cessation of active bleeding. The postoperative phase was uneventful and the patient was discharged home on postoperative day three. His postoperative visit at five months later was unremarkable.

Endovascular therapy for palliative care of cancer patients

Interventional radiology procedures often play an integral role in the diagnosis and treatment of patients with cancer. In the latter stages of cancer treatment, palliative care therapies may be sought for improvement in the quality of remaining life for oncology patients. Increased awareness among interventionalists and referring oncologists regarding minimally invasive treatments for palliation is desirable to provide additional options for patients. In particular, endovascular therapies can provide control of symptoms and complications related to incurable malignancies.

Successful management of life-threatening choriocarcinoma syndrome with rupture of pulmonary metastatic foci causing hemorrhagic shock

We report a case of a man with testicular cancer metastatic to the lung and retroperitoneal lymph node, with significant elevation of serum levels of human chorionic gonadotropin, 534,000 mIU/mL. Just after the initiation of chemotherapy, life-threatening hemothorax occurred and hemorrhagic shock ensued. The pulmonary tumor had broken off, and lower lobectomy was carried out. Pathologic examination of the specimen revealed choriocarcinoma and yolk sac tumor. Through multimodal treatments he achieved complete remission. To our knowledge, this is the first case report of choriocarcinoma syndrome with life-threatening hemorrhage caused by rupture of pulmonary metastases, resulting in complete remission through multimodal treatments.

Présentation inhabituelle d'un choriocarcinome gestationnel

Gestational choriocarcinoma is a rare malignant tumour with a strong metastatic potential. We report a case of a 31-year-old patient with a gestational trophoblastic tumor revealed by renal and pulmonary metastases, one year after a normal pregnancy. The diagnosis was established by the pathologist on the radical nephrectomy specimen. The evolution was quickly favorable after adequate treatment using multiagent chemotherapy. This case highlights the polymorphic aspects of the gestational choriocarcinoma and stresses the importance of a betaHCG assessment anytime abnormal symptoms occur in the outcome of a pregnancy.
