Cardiac metastasis from carcinoma of the cervix: report of two cases

Cardiac metastasis in uterine cervical cancer : A systematic review and case study

PURPOSE

Cardiac metastasis from cervical cancer is rare and only scarcely documented. We aim to present a new case and systematically summarize the available literature.

MATERIALS AND METHODS

PubMed, Scopus, Web of Science, Central, and ClinicalTrials.gov were systematically searched following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) criteria. Results were screened via title, abstract, and full text. Additionally, the reference lists of all papers chosen for the review were screened.

RESULTS

Eighty-one papers were identified, describing 86 cases in total. Cardiac metastasis occurred at all stages of cervical cancer and in all age groups. Median time from initial diagnosis to diagnosis of cardiac metastasis was 12 months. Patients mainly complained of dyspnea and chest pain, 60.8% had pathologic ECG (electrocardiographic) findings. The cardiac mass was most frequently detected by transthoracic echography. The most common tumor histology was squamous cell carcinoma. Chemotherapy and surgical interventions were the main treatment modalities. Median survival after diagnosis of cardiac metastasis was 3 months.

CONCLUSION

This largest review on cardiac metastases from cervical cancer confirmed the heart as a very infrequent site of metastasis. There are < 100 cases described in the literature, with very poor prognosis and undefined clinical management.

A Rare Encounter With Unusual Metastasis: Metastatic Right Ventricular Tumor Secondary to Cervical Cancer

Metastasis of cervical cancer to the heart is rare. Cervical carcinoma typically spreads to the lungs, liver, bones, and lymph nodes via hematogenous, lymphatic, transvenous, or direct extension. Cardiac metastasis from cervical carcinoma is uncommon and portends a dismal prognosis, with mean survival under six months post-diagnosis. A high index of suspicion and multimodal imaging is imperative for prompt diagnosis and improved outcomes in these patients. Here, we report a rare case where a 41-year-old African American female with stage IIIB cervical squamous cell carcinoma (SCC) presented with exertional dyspnea and chest pain concerning pulmonary embolism (PE). Computed tomography angiography showed no PE but revealed a right ventricular (RV) mass and diffuse pulmonary nodules. Echocardiography suggested an RV tumor versus a thrombus. Cardiac magnetic resonance imaging demonstrated a large RV infiltrative mass favoring metastasis over thrombus. A biopsy of one of the pulmonary nodules confirmed metastatic SCC. Despite treatment, the prognosis was poor.

Intracavitary cardiac metastasis of cervical squamous cell carcinoma with immune thrombocytopenia: a rare case report

Cervical cancer is a prevalent gynecological malignancy; however, intracavitary cardiac metastasis of cervical squamous cell carcinoma is exceptionally rare. In addition, the co-occurrence of cervical cancer and right ventricular cancer thrombus with autoimmune diseases is extremely uncommon. Furthermore, the role of immune checkpoint inhibitors in the treatment process of such cases remains controversial. Given the scarcity of reported cases, it is imperative to document and highlight this unique presentation, providing novel insights into diagnosis and management strategies. We present the case of an adult patient diagnosed with cervical cancer and concurrent right ventricular cancer thrombus, accompanied by immune thrombocytopenia (ITP). The patient exhibited resistance to conventional ITP drugs, with suboptimal platelet response. However, upon achieving initial control of the tumor, the patient's platelet counts returned to normal. Notably, the addition of immune checkpoint inhibitors targeting PD-L1 resulted in effective tumor control, accompanied by sustained high platelet levels. Unfortunately, during subsequent anti-tumor therapy, the patient experienced a prolonged platelet rise time, rendering continuous effective anti-tumor therapy and anticoagulant therapy unattainable. This led to a gradual increase in intraventricular thrombosis, ultimately resulting in the patient's demise due to circulatory failure. This rare case sheds light on the potential alleviation of ITP in patients with tumor complications through effective antitumor therapy. The successful control of ITP after tumor management highlights the importance of integrated treatment approaches. Furthermore, the inclusion of immune checkpoint inhibitors demonstrated their potential role in achieving tumor control and maintaining platelet levels. However, the prolonged platelet rise time observed during subsequent therapy underscores the challenges in maintaining both effective anti-tumor therapy and anticoagulant therapy, necessitating careful management strategies. This case report emphasizes the need for a comprehensive evaluation and tailored therapeutic interventions in similar complex scenarios. In summary, this case report offers valuable clinical insights into the management of intracavitary cardiac metastasis of cervical squamous cell carcinoma, the coexistence of immune thrombocytopenia, and the potential implications of immune checkpoint inhibitors in such cases. Understanding these rare occurrences and their clinical impact can contribute to improved diagnostic approaches, therapeutic decision-making, and patient outcomes.

Intracardiac metastasis from unknown uterine cervical cancer with severe thrombocytopenia

INTRODUCTION

Cardiac metastasis is relatively common in malignant neoplasms, such as lung cancers, breast cancers, melanomas, lymphomas, and leukemias. In contrast, cardiac metastasis of uterine cervical cancer, solitary metastasis to the heart, and tumors inducing severe thrombocytopenia are rare.

CASE REPORT

The present patient was a 52-year-old female who was diagnosed with a solitary cardiac tumor prior to uterine cervical cancer and presented with severe thrombocytopenia. Our case had two remarkable aspects: 1) successful treatment under the condition of severe thrombocytopenia in association with the presence of a cardiac tumor, and survival without recurrence of the carcinoma one year after surgery; and 2) a solitary cardiac metastatic tumor larger than the primary uterine cervix carcinoma.

COMMENT

we report an extremely rare case of solitary cardiac metastasis of uterine cervical cancer, which wassuccessfully treated. One year after cardiac surgery, the patient is alive without recurrence of the carcinoma.

Cardiac Tamponade as an Initial Manifestation of Cervical Cancer

Cervical cancer is the second most common malignancy worldwide in women and the third most common cause of cancer death in developing countries. This type of cancer spreads mainly to the lung, the bone, and the brain; however, the pericardium is an unusual site of invasion, which is associated with a poor prognosis. We present a case of a 35-year-old woman with six months of leg edema and abnormal uterine bleeding. During the initial evaluation, cardiac tamponade and a bilateral pleural effusion were found. A left supraclavicular lymphadenopathy was identified on physical examination, while gynecological examination and MRI were irrelevant. Initial cytology of the pericardial fluid showed a poorly differentiated carcinoma, and a cervical biopsy revealed a squamous cell invasive carcinoma. Chemotherapy was started with carboplatin and paclitaxel, but no clinical improvement was noted and the patient died 46 days after arrival. Cardiac tamponade in a young female patient is a harbinger to widen the differential diagnosis to include not only infectious, cardiac, or metabolic etiology but also oncological causes since this will allow appropriate treatment.

Effective cardiac radiotherapy relieved life-threatening heart failure caused by advanced small cell lung cancer with cardiac metastasis: a case report

Cardiac radiotherapy is rarely used in clinical practice because of concern of adverse effects on the heart. We present a case of a 64-year-old man with advanced small cell lung cancer (SCLC) treated with chemo-radiotherapy who attained partial remission initially but had disease progression to bulky cardiac metastasis and significant pericardial effusion. Severe heart failure with hepatic failure was found. Chemotherapy and pericardiocentesis were contraindicated because of the associated high risk and bleeding tendency. Emergent palliative cardiac radiotherapy resulted in rapid improvements of dyspnea, liver function, and urine output. Pericardiocentesis was performed 5 days later and effusion cytology confirmed metastatic SCLC. To our knowledge, this is the first case of effective cardiac radiotherapy for SCLC with life-threatening cardiac metastasis. Palliative cardiac radiotherapy may be an effective alternative treatment for radiosensitive malignancy with cardiac metastasis in cases of multiple organ dysfunction and unsuitability for chemotherapy and pericardiocentesis.

Right ventricular metastatic tumor from a primary carcinoma of uterine cervix: A cause of pulmonary embolism

The presence of intracavitary cardiac metastasis from squamous cell carcinoma of the uterine cervix is extremely rare. The diagnosis is made almost exclusively postmortem. Apart from causing intracardiac obstruction, it can present as pulmonary emboli and the prognosis is extremely poor. It is important to suspect this diagnosis in patient with recurrent pulmonary emboli. Due to the rarity of this condition it is very difficult to standardize care for these patients. However, it is possible that aggressive therapy may lengthen patients' survival and quality of life. We present a case of isolated intracavitary cardiac metastasis arising from a squamous cell carcinoma of the cervix, 44-year-old woman, diagnosed as stage complaint of fatigue and dyspnea on mild exertion. The echocardiogram showed a mass in the right ventricle and suspicious pulmonary embolism. We took an aggressive therapeutic approach. The pathological examination of the resected tissue revealed metastatic squamous cell carcinoma.

Biventricular metastatic invasion from cervical squamous cell carcinoma

Metastasis to the heart has been previously described with primary lung and breast carcinoma, lymphoma, leukaemia, mesothelioma and melanoma. However, left-ventricular cardiac metastasis from primary cervical squamous cell carcinoma is poorly described. This report describes the clinical presentation of a patient with cardiac metastatic invasion from cervical cancer.

Cardiac metastasis in cervical cancer

Metastasis of cervical carcinoma to the heart is uncommon. Most cases are found during autopsy. These type of metastasis occur mostly in epicardium and myocardium. We present a case report of a patient with carcinoma cervix stage IIIB who presented to the hospital with pitting edema of right lower limb, post 1 year of completion of treatment. PET-CT scan showed FDG avid inguinal, iliac and retroperitoneal lymph nodes, which were bulky on right side causing pedal edema. There was FDG avid uptake seen in right atrial wall and in the atrioventricular groove indicative of metastasis to the heart. Patient refused biopsy or further treatment and hence received best supportive care only. She had a disease free survival of 12 months, and survived for 11 months after being diagnosed with recurrence. Overall survival was 23 months.

Solitary cardiac metastasis of uterine cervical cancer with antemortem diagnosis: A case report and literature review

Cardiac metastasis of uterine cervical cancer with antemortem diagnosis is extremely rare. Therefore, its landscape epidemiology has not been well elucidated to date. In the present study, a case of solitary cardiac metastasis of uterine cervical cancer diagnosed antemortem is reported, and a review of the currently available literature (which includes 18 cases of cardiac metastasis of uterine cervical cancer) is conducted. In January 2013, a 78-year-old woman with squamous cell carcinoma (SCC) of the uterine cervix (International Federation of Gynecology and Obstetrics stage IIIb) underwent definitive radiotherapy at Gunma University Hospital (Gunma, Japan). Follow-up examination at 5 months after completion of the treatment indicated no evidence of recurrence or metastasis. In April 2014, the patient reported epigastric discomfort and general malaise. Electrocardiogram suggested myocardial dysfunction. Transthoracic echocardiography revealed the presence of a mass occupying the right ventricle and pericardial effusion. Cine magnetic resonance imaging demonstrated a filling defect in the right ventricle, and transcatheter biopsy confirmed SCC. The patient was diagnosed with a solitary cardiac metastasis of uterine cervical cancer. Despite aggressive medical therapy, the patient succumbed to disease 31 days after admission to hospital. A review of the current literature revealed that 84% of cases of cardiac metastasis develop within 2 years of completion of the initial treatment, and that electrocardiogram and echocardiography reveal findings of myocardial dysfunction and the presence of a mass in the right ventricle, respectively. A treatment strategy for cardiac metastasis of uterine cervical cancer has not been standardized thus far, and the prognosis is very poor, as the majority of patients succumbed to disease within 1 year. In summary, the current case and the literature review conducted in the present study suggest that: i) Cardiac metastasis should be included in the differential diagnosis in cases with nonspecific complaints such as epigastric discomfort and general malaise when patients have a history of uterine cervical cancer, particularly within the previous 2 years; and ii) electrocardiogram and echocardiography are convenient and effective modalities for the diagnosis of cardiac metastasis of uterine cervical cancer.

Role of palliative radiotherapy in the management of mural cardiac metastases: who, when and how to treat? A case series of 10 patients

Cardiac metastases (CM), although a rare manifestation of metastatic cancer, are increasing in incidence with the improved prognosis and increased longevity of many patients with cancer. This condition may be life‐threatening, especially for bulky rapidly growing tumors. Such cancer presentations may be amenable to palliative radiotherapy to improve symptoms and to prevent further cardiac function decline. Here, we report on our experience with 10 patients with mural CM who received radiotherapy (RT) to the heart with palliative intent. The radiation treatment was given in different clinical situations using different dose and fractionation, and with a variety of outcomes. Palliative RT was a reasonably effective treatment, leading to good radiographic response in five patients who were evaluable for radiologic response. The mean duration of response in responding patients was 6.3 months (range: 3–11 months). This report describing clinical dilemmas around CM radiation therapy summarizes the previous experiences with radiation in treatment of CM and may assist in the considerations of palliative treatment for these patients.

A case of cardiac metastasis from uterine cervical carcinoma

Cases of cardiac metastasis from uterine cervical carcinoma are rare. While they are occasionally found on autopsy, antemortem recognition is extremely rare. We confirmed a case of cardiac metastasis from cervical carcinoma antemortem, because we observed a decrease in platelet count during the course of treatment. The patient was a 27-year-old woman diagnosed with stage Ib1 uterine cervical carcinoma. Radical hysterectomy with pelvic lymphadenectomy was performed. Para-aortic lymph node metastasis was detected on positron emission tomography/computed tomography (PET-CT). Adjuvant chemotherapy was started, and most of the metastatic lesions disappeared. Pelvic lymph node recurrence was suspected on PET-CT during continued chemotherapy; therefore, treatment was shifted to radiation therapy. Tumor shrinkage was recognized, and the initial therapy was completed. A noticeable decrease in platelet count was recognized seven months after treatment. Multidetector CT was performed, and an intracardiac tumor was detected. The patient did not desire any further treatment. She died three weeks after the intracardiac tumor was confirmed. Few previous autopsy studies have reported cardiac metastasis from cervical carcinoma. Thus, it is necessary to consider the possibility of cardiac metastasis for patients diagnosed with terminal cervical carcinoma.

Diagnosis of cardiac metastasis from cervical cancer in a 33-year-old patient using multimodal imaging studies: a case report and literature review

We report a case of a 33-year-old woman with emergency admission due to dyspnoea and fever. History included squamous cell carcinoma of the cervix in complete remission. Contrast-enhanced computed tomography (CT) scanning of the chest, which was indicated to rule out pneumonia, revealed an infiltrative cardiac mass. Further assessment of the tumour by echocardiography and cardiac magnetic resonance imaging (MRI) showed transmural infiltration of the apical interventricular septum with a mass extending into the left and right ventricle cavities. The mass was highly suspicious for a cardiac metastasis. Cardiac metastases from cervical cancer are extremely rare. Recurrence of cervical carcinoma involving the heart should be considered even after a curative therapy approach. Non-invasive imaging plays a paramount role in investigating cardiac masses. Echocardiography, CT and MRI are complementary imaging modalities for complete work-up of intracardiac lesions.

Intracardiac metastasis from known cervical cancer: a case report and literature review

Cardiac metastasis from known cervical cancer is rare. Even through a routine check-up, this type of metastasis can present as pulmonary emboli. Suspicion of this diagnosis in an oncology patient with complicating pulmonary emboli but no evidence of deep vein thrombosis is important, especially in cervical cancer patients with extensive pelvic lymph node metastasis and vascular invasion of a primary tumor. Early recognition may aid in improving the prognosis. We present a case of intracardiac metastasis arising from a squamous carcinoma of the cervix in a patient with pulmonary tumor emboli and review other cases from the literature.

Cervical Cancer With Cardiac Metastasis

A 48-year-old woman presented with fatigue and vaginal spotting and was subsequently diagnosed with squamous cell cancer of the cervix. Computed tomography and positron emission tomography scans suggested widespread disease including possible involvement of the right ventricle. A 2D echocardiogram with Doppler showed a large right ventricular mass obstructing the tricuspid valve inflow. This report demonstrates the use of echocardiography and Doppler ultrasound in the diagnosis of a rare case of cardiac metastasis from cervical cancer.

Radiotherapy is effective for a primary lung cancer invading the left atrium

Atrial involvement is an uncommon feature of advanced non-small-cell lung cancer, occurring in up to 10% of patients with bronchogenic carcinoma. Additionally, cardiac metastases from other sources are documented in up to 7% of cancer patients at autopsy. Because atrial invasion can lead to systemic embolisation and/or outflow obstruction, it is treated regardless of the overall prognosis. While the gold standard treatment has historically been surgical resection, advances in radiotherapy allow for the safe treatment of cardiac disease. Here we present the case of a woman with pulmonary adenocarcinoma of the left lower lobe that progressed to invade the pulmonary vein and left atrium while maintained on standard chemotherapy. She was treated with intensity-modulated radiotherapy and had a complete response in terms of her atrial disease within 3 months. She suffered no acute toxicity or complications as a result of the radiation therapy.

Infratemporal fossa metastasis from carcinoma of the uterine cervix

INTRODUCTION

Carcinoma of the uterine cervix is the fourth commonest malignant tumor in women. The disease spreads into the surrounding tissues by direct infiltration whereas spread by hematogenous dissemination is relatively unusual, and most commonly involves the lung, bone, and liver. The involvement of oral and maxillofacial region is extremely rare in gynecological cancer.

CASE REPORT

In this paper, we present an unusual case of a metastatic squamous cell carcinoma originating in the infratemporal fossa of a 37-year-old woman who had underwent a subtotal hysterectomy, for squamous cell carcinoma of the cervix, 22 months earlier. A whole-body CT scan revealed a mass of enlarged lymph nodes in the mediastinum as well. The patient, who had presented for evaluation of a rapidly increasing trismus associated with deep intermittent facial pain and temporal swelling had initially been treated for a TMJ dysfunction and later for an infratemporal fossa abscess for long before a definite diagnosis was made. A high index of suspicion is possible to make an early diagnosis, which when coupled with an aggressive management can improve survival and quality of life.

Successful radiation treatment of anaplastic thyroid carcinoma metastatic to the right cardiac atrium and ventricle in a pacemaker-dependent patient

Anaplastic thyroid carcinoma (ATC) is a rare, aggressive malignancy, which is known to metastasize to the heart. We report a case of a patient with ATC with metastatic involvement of the pacemaker leads within the right atrium and right ventricle. The patient survived external beam radiation treatment to his heart, with a radiographic response to treatment. Cardiac metastases are usually reported on autopsy; to our knowledge, this is the first report of the successful treatment of cardiac metastases encasing the leads of a pacemaker, and of cardiac metastases from ATCs, with a review of the pertinent literature.

Malignant pericardial effusion with cardiac tamponade in a patient with metastatic vaginal adenocarcinoma

Malignant pericardial effusion with cardiac tamponade is a rare manifestation of metastatic gynecological cancer. A 35-year-old female was diagnosed with clear cell adenocarcinoma of the vagina. Four years after partial vaginectomy, she developed regional recurrence and was treated with surgical excision followed by platinum-based chemotherapy and radiation therapy. Six years later, the patient was diagnosed with lung metastases and received a combination adriamycin and platinum-based chemotherapy. Shortly after completing treatment, she presented with weakness and was found to be hypotensive on physical exam. Computed tomography scan confirmed a pericardial effusion with evidence of bilateral heart failure. She underwent an emergent pericardiocentesis and eventual pericardial window procedure. Metastatic adenocarcinoma of the vagina can present with malignant pericardial effusion with cardiac tamponade. Therefore, gynecologists and gynecological oncologists need to be familiar with the diagnosis and management of this disease process.

Recurrence of cervical carcinoma manifesting as cardiac metastasis three years after curative resection

We report a rare case of cardiac metastasis from carcinoma of the uterine cervix. A 58-year-old woman presented with multiple pulmonary emboli, disseminated intravascular coagulation, and right heart failure 43 months after a curative resection of cervical carcinoma (stage IB1). Transthoracic echocardiography and computed tomography revealed large tumors in the right ventricle and right main pulmonary artery. No evidence of recurrence was obtained in the pelvis and abdomen. Surgical removal of the tumors remarkably improved her general condition, which had been declining progressively. The patient declined further treatment, including adjuvant chemotherapy, and was followed in the outpatient clinic. The right ventricular tumor recurred 4 months later and she died of heart failure. The possibility of late recurrence of cervical carcinoma in the heart should be considered even after curative resection.

Oral squamous carcinoma in a patient with cervix cancer: use of human papillomavirus analysis to differentiate synchronous versus metastatic tumor

BACKGROUND

Cervical cancer usually spreads by direct infiltration and disseminates by lymphatic and hematogenous pathways. The common sites of distant metastases are the lungs, liver, and bones. Other rare metastatic sites have been previously described including only one case of oral cavity metastasis.

CASE

We present here the second case of a patient with apparent oral cavity metastasis from cervical cancer. By cloning specific human papilloma virus (HPV) genomic regions, the two lesions showed HPV genomic sequences from different viruses (18 and 33, for the uterine cervix and the oral cavity, respectively), thus indicating the oral lesion as a synchronous second primary tumor.

CONCLUSION

The use of molecular markers to distinguish between a secondary and a primary lesion is recommendable in cervical cancer, particularly when reporting rare site metastases.

Selective activation of cervical microvascular endothelial cells by human papillomavirus 16-e7 oncoprotein

BACKGROUND

Human papillomavirus type 16 (HPV16) is strongly implicated in the etiology of cervical cancer, with the expression of HPV16-encoded E7 oncoprotein in infected epithelial cells contributing to their malignant transformation. Although nuclear E7 interacts with several nuclear targets, we have previously shown that extracellular E7 can cause suppression of immune cell function. Moreover, cervical microvascular endothelial (CrMVEn) cells treated with E7 increase their expression of adhesion molecules. High levels of some cytokines in serum and in cervicovaginal secretions are associated with the progression of cervical cancer. In this study, we investigated the effects of extracellular E7 on cytokine production and on cytoskeleton structure of CrMVEn cells and vascular endothelial cells from different organs.

METHODS

Immunocytochemical staining and flow cytometry techniques were used to detect E7 in endothelial cells incubated with purified E7 protein. Laser scanning confocal microscopy was used to study the E7-induced modification of the endothelial cytoskeleton. An enzyme-linked immunosorbent assay was performed to measure the production of two cytokines, interleukin 6 (IL-6) and interleukin 8 (IL-8), by E7-treated endothelial cells. All statistical tests were two-sided.

RESULTS

Extracellular E7 was taken up by CrMVEn cells and localized to the cytoplasm. CrMVEn cells showed a statistically significant (P<.02) increase in the production of IL-6 and IL-8 after treatment with E7 compared with the controls. CrMVEn cells also produced higher levels of these cytokines than did the other endothelial cells (P<.01). E7 also induced marked alterations in the endothelial cytoskeleton of CrMVEn cells as a result of actin fiber polymerization.

CONCLUSION

These findings suggest a novel mechanism by which E7, as an extracellular factor, can play a role in the progression and dissemination of cervical cancer via its selective effects on endothelial cells.
