The role of estrogen deprivation therapy in premenopausal women with primary unresectable intracardiac leiomyomatosis: a systematic review and meta-analysis

BACKGROUND

Intracardiac leiomyomatosis (ICLM) is a rare life-threatening form of intravenous leiomyomatosis (IVLM). The incomplete resection and recurrence are associated with high morbidity and mortality. The objective of this study is to identify that whether estrogen deprivation therapies, including bilateral salpingo-oophorectomy (BSO)-based surgery and gonadotrophin releasing hormone agonists (GnRHa) administration, could bring benefits to patients with primary unresectable ICLM.

METHODS

PubMed/MEDLINE (Ovid) was searched (up to May 2021) for studies reporting individual patient data on demographics, clinicopathological features, treatment, and follow-up information. Exclusion criteria were patients who may have been included in two or more publications. This study was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.

RESULTS

A total of 114 patients from 70 papers were included. Several reports showed that the tumor in the right atrium and inferior vena cava shrank dramatically after BSO-based surgery, or GnRHa administrated preoperatively in premenopausal women. The rate of complete resection was 64.04% in patients with ICLM, which was 85.25% in no/slight adhesion and no pulmonary nodules group, while 22.22% in firm/extensive adhesion and/or pulmonary nodules group (p < 0.0001). Meanwhile, the recurrence rates in patients with complete resection and incomplete resection were 4.29% and 37.84% respectively (p < 0.0001). Furthermore, complete resection with BSO had the lowest recurrence rate of 3.13%, incomplete resection with BSO had a progression rate of 45.45%, while incomplete resection with ovarian preservation had the highest progression rate of 75.00%.

CONCLUSIONS

The recurrence rate of ICLM was closely related to firm/extensive adhesion in IVC or above, and/or pulmonary nodules. BSO-based surgery might reduce the recurrence rate no matter ICLM could be completely resected or not. In addition, estrogen deprivation therapies could decrease tumor burden as a primary treatment, and further make a secondary complete resection feasible in premenopausal women with initially unresectable ICLM.

Non-open-heart surgery for intravascular leiomyomatosis extending from the inferior vena cava to the right heart chamber

OBJECTIVE

In the present study, we analyzed the advantages and feasibility of non-open-heart surgery without cardiopulmonary bypass for intracardiac intravenous leiomyomatosis.

METHODS

We retrospectively reviewed 23 cases of intracardiac intravenous leiomyomatosis and divided them into a noncardiopulmonary bypass (NCPB) group (9 cases) and a cardiopulmonary bypass (CPB) group (14 cases) according to the surgical treatment received. The clinical characteristics and anatomic features, including the diameter of the tumor, right atrium, and inferior vena cava, were recorded, and the perioperative data, including the operation time, blood loss, postoperative hemoglobin change, and follow-up results, were analyzed and compared between the two groups.

RESULTS

The NCPB group had required a shorter operation time (321.9 ± 104.2 minutes vs 526.3 ± 95.6 minutes; P < .001) and had experienced less blood loss (456.3 ± 249.9 mL vs 815.4 ± 435.6 mL; P = .048) compared with the CPB group. The NCPB group had a small maximum cross-sectional area of the tumor inside the right atrium (475.5 ± 509.6 mm²), a low proportion of the maximum cross-sectional area of the entrance of the right atrium (average, 26.1%), no tricuspid valve or atrial wall involvement, and high mobility inside the inferior vena cava and heart chamber. All 23 patients had recovered well postoperatively, and no recurrence had developed during 24 months of follow-up.

CONCLUSIONS

For intravenous leiomyomatosis with a smaller cross-sectional area in the right atrium that can be mobilized, surgery without CBP is feasible and should be considered.

Intravenous leiomyomatosis: Case series and review of the literature

Background

We retrospectively reviewed the data of three patients with intravenous leiomyomatosis (IVL), one of whom had intracardiac leiomyomatosis, and analyzed their clinical symptoms, preoperative assessment findings, operative approaches, and recurrence.

Case presentation: The present study describes three cases of IVL extending into the inferior vena cava, even as far as the right atrium and ventricle, and discusses the imaging findings and differential diagnosis of this tumor entity. The three patients, two of whom were diagnosed during the first operation and one of whom had a giant pelvic mass, were surgically treated with complete tumor resection, hysterectomy, and bilateral salpingo-oophorectomy. The pathological examination findings were suggestive of IVL. The duration of time from the first myomectomy or hysterectomy to IVL occurrence ranged from 2 to 18 months. No signs of recurrence were observed during follow-up. Computed tomography and magnetic resonance imaging played a vital role in the diagnostic process and presurgical assessment.

Conclusion

In clinical practice, IVL should be considered before surgery for a broad ligament myoma or giant pelvic mass. Surgery should always aim for complete tumor excision and include hysterectomy and bilateral salpingo-oophorectomy. Vascular reconstruction computed tomography is a good choice for diagnosis and follow-up.

Surgical Strategy for Intravenous Cardiac Leiomyomatosis

Intravenous-cardiac leiomyomatosis (IVCL) is a rare, histologically benign but biologically aggressive tumour. Accurate diagnosis and appropriate treatment choices are important for prognosis. The best surgical approach remains unclear owing to limited evidence. This study aimed to assess surgical strategies for treating IVCL and to propose individualised surgical strategies. We searched PubMed, Web of Science, and the Cochrane Library to identify case reports and case series published in English over the last 10 years. Two (2) reviewers independently screened the literature according to the inclusion and exclusion criteria, and subsequently extracted data. One hundred and ten (110) cases were included. According to our analysis, IV cardiac leiomyomatosis is most common in the fifth decade, and the mean age at detection is 45.71±7.67 years. Most patients had undergone previous hysterectomy/myomectomy, or had a co-existing uterine leiomyoma when admitted. The most common clinical presentations were dyspnoea, palpitation, pelvic mass, and leg oedema. More patients benefited more from one-stage surgery. Seventy-eight per cent (78%) of cases experienced a surgical approach of thoracic and abdominal incisions. Extractions of IVCL were varied. Eighty-seven (87) patients experienced cardiopulmonary bypass and deep hypothermic circulatory arrest was performed on 64.4% of them. Total hysterectomy and bilateral oophorectomy, together with pelvic leiomyoma excision, were done in 76.0% of patients. Overall, surgical strategies for IVCL are varied; the optimal strategy required consideration of multiple factors. Complete resection is recommended for both single- and two-stage operations. Once complete resection is achieved, recurrence is rare.

Intracardiac extension of intravenous leiomyoma, a rare phenomenon: A case report

Leiomyoma of uterine origin is a common histologically benign neoplasm in women; however, growth intravenously with intracardiac extension is a rare phenomenon. This is a diagnostic challenge that can present with varied clinical manifestations and multiple differential diagnosis. This is a case of a 45-year-old female patient with chest heaviness and an intracardiac mass on 2-dimensional (2D) echocardiogram. Previous history of hysterectomy was likewise noted. Imaging workup, including 2D echocardiogram and contrast-enhanced chest and abdomen computed tomography scans, was performed which demonstrated a large, heterogeneous, elongated filling defect in the right atrium and right ventricle extending to the inferior vena cava, left renal vein, and left gonadal vein. The diagnosis was made after resection of the tumor in a single-stage operation. The histopathologic and immunoprofile of the resected tumor were consistent with leiomyoma. The use of multiple imaging modalities such as 2D echocardiogram and computed tomography are essential in the investigation of the intracaval masses with intracardiac extension. Although intravenous leiomyoma with intracardiac extension is a rare phenomenon, radiologists and clinicians alike should be mindful of this differential diagnosis.

Inguinal pain and fullness due to an intravascular leiomyoma in the external iliac vein

Intravascular leiomyomatosis (IVL) is a benign smooth muscle tumor that evolves from the pelvic veins and can spread to the central veins and heart. Cardiac involvement is the most commonly reported presentation. Initial diagnosis is difficult, and IVL is commonly misdiagnosed as thrombus or atrial myxoma. Appropriate imaging and a high clinical suspicion are required for accurate diagnosis. We report a rare case of IVL in the external iliac vein that recurred 4 years after hysterectomy. Only four cases have been reported in the literature to involve the external iliac vein as it has no direct connection to pelvic venous drainage.

Intravenous leiomyomatosis with intracardiac extension depicted on computed tomography and magnetic resonance imaging scans: A report of two cases and a review of the literature

Intravenous leiomyomatosis (IVL) is defined as a benign smooth muscle tumor, growing within systemic veins. IVL with intracaval and intracardiac extension has rarely been reported in radiological and oncological journals. The present study describes 2 cases of IVL extending from the inferior vena cava to the right atrium and ventricle, and discusses the imaging findings and differential diagnosis of this tumor entity. The two patients, who complained of palpitations, shortness of breath or syncope, were surgically treated, with complete resection of the cardiac and intracaval tumors. Pathological examinations were suggestive of IVL. The postoperative course of the two patients was uneventful, and no signs of recurrence were observed on follow-up. Computed tomography and magnetic resonance imaging played a vital role in the diagnostic process and presurgical assessment. The results of the present study indicate that IVL should be considered upon presentation of a soft mass in systemic veins, even when the mass extends to the right cardiac chambers, in female patients, particularly in patients with a history of uterine myoma.

Multimodality Evaluation of Intravenous Leiomyomatosis: A Rare, Benign but Potentially Life-Threatening Tumor

BACKGROUND

Intravenous leiomyomatosis (IVL) is a rare tumor, which is usually of uterine origin, characterized by intravascular nodular masses of histologically benign smooth muscle that may extend variable distances, including into the inferior vena cava, right atrium and pulmonary arteries. Tumors may arise from uterine leiomyoma, walls of the uterine vessel, or myometrium. It usually occurs at between 20-70 years of age with a median age of 45 years. The most commonly affected women are pre-menopausal and multiparous. Intra-cardiac extension may represent a diagnostic challenge as it is usually misdiagnosed as a right atrial myxoma and may cause multiple symptoms, such as shortness of breath, tachycardia, chest pain, syncope, and even death.

CASE REPORT

We present the case of a 40-year-old female patient with past medical history of arterial hypertension, who was referred to a cardiovascular center due to an intra-cardiac mass found on 2D echocardiogram. The patient was given the rare diagnosis of intravenous leiomyomatosis of the uterus with extension into the gonadal veins, inferior vena cava, right atrium, right ventricle, and main pulmonary arteries. Imaging workup including trans-esophageal echocardiogram, cardiac catheterization, contrast-enhanced abdomen and pelvic CT scans, and cardiac MRI was performed for evaluation.

CONCLUSIONS

Intravenous leiomyomatosis is a rare diagnosis that merits consideration in a young pre-menopausal female patient with cardiac symptoms associated with a right atrial mass. Radiologists play a vital role in the diagnosis and follow-up of patients with the diagnosis of intravenous leiomyomatosis. Differential diagnosis includes vascular thrombus as well as primary and metastatic tumors. Early detection is imperative for appropriate treatment and surgical planning.

Successful multiple-step management of intravenous leiomyomatosis diagnosed after episode of acute abdominal pain: Case report and review of literature

•

Intravenous leiomyomatosis could be defined as the extrauterine extension of smooth-muscle cells.

•

IVL causes systematic complications and is characterized by increased possibility of recurrence.

•

Diagnosis is an issue of high clinical difficulty.

•

Surgical resection of IVL either in one or in multiple-step strategy remains the optimal approach.

Introduction

We present the case of a 37-year old woman diagnosed with intravenous leiomyomatosis (IVL) that was managed uneventfully with multiple-step management.

Presentation of case

A 37-year-old woman was admitted because of acute abdominal pain. Emergency Computed Tomography demonstrated a big pelvic mass 5 × 15 cm of heterogenous composition intaking the contrast agent. Total hysterectomy with salpingoophorectomy was proposed to patient, however, patient expressed her will for fertility preservation and gave consent only for the resection of a single ovary. Laparotomy revealed the presence of myoma, multiple lesions of potential adenomyosis and cordon-shaped formations arising from uterus and extending mainly to left ovary. Final histological diagnosis was intravenous leiomyomatosis (IVL). MRI angiography revealed the presence of residual lesions in inferior vena cava. Laparoscopic resection was performed one month after laparotomy and left ovary was resected without complications. Venovenous bypass was finally performed three months later from initial surgery. The process was significantly labored, resulted in the successful resection of intravenous lesions but was complicated intraoperatively by right kidney rupture. After a follow-up of 33 months, case remains uncomplicated without signs or symptoms of potential recurrence.

Discussion

Intravenous leiomyomatosis represents a rare clinical entity histologically bening but clinically aggressive. No consensus exists regarding the optimal management, especially in cases with initial will for fertility preservation.

Conclusion

IVL represents a rare clinical entity often presenting difficulties in diagnosis and optimal treatment. Large case-series studies should be encouraged to assess the optimal management.
