Leiomyosacroma of the inferior vena cava is an extremely rare malignancy originating from the tunica media of the venous wall. Its symptoms and radiomorphological signs do not always lead to an accurate diagnosis. Histological sampling can be dangerous due to its location. Therefore the diagnosis is often a challenge for clinicians. Its treatment is primarily surgical, supplemented by radiotherapy and chemotherapy applied together or in monotherapy. In our case, an asymptomatic 74-year-old female patient was diagnosed with a tumor of the inferior caval vein located just above the right renal vein and involving the right adrenal gland. As serum cortisol, epinephrine, norepinephrine, adrenocorticotropic hormone (ACTH), total and free testosterone, dehydroepiandrosterone sulfate (DHEA-S), sex hormone binding globulin (SHBG) was at normal level, the tumor showed no hormone secretion. Primary surgical resection was planned. Preoperative biopsy was not performed due to its high risk of complications. During operation, tumor resection was performed by resection of the venous wall, removal of the right adrenal gland and neoimplantation of the right renal vein. For better exposure, cholecystectomy was also performed at the beginning of surgery. There were no postoperative complications. The patient received adjuvant radiation therapy. Thanks to the early diagnosis of the tumor and the complete resection, we significantly increased the patient’s chances of total recovery. With the radiotherapy performed, we reduced the likelihood of tumor recurrence.

Though generally considered benign, angiomyolipomas can invade through the renal vein into the inferior vena cava, putting patients at risk of catastrophic pulmonary fat embolization. Venous invasion is thus an indication for surgical resection but is thought to increase the risk of adverse operative outcomes including intraoperative hemorrhage and embolization of fat and/or tumor thrombus. We report a novel approach to mitigating these complications illustrated in the case of a 43-year-old woman with IVC-invasive renal AML who underwent successful radical nephrectomy after concurrent pre-operative renal artery embolization and placement of a retrievable suprarenal IVC filter., (Copyright © 2017 Elsevier Inc.

A case of locally advanced thymic carcinoma that was successfully resected with the great vessels after chemoradiation therapy is reported. A 57-year-old man with Masaoka stage III thymic carcinoma received two cycles of cisplatin/docetaxel and 60 Gy irradiation. The response was stable disease with 19% size reduction, and a radical resection with the ascending aorta and superior vena cava with the patient under circulatory arrest with the use of cardiopulmonary bypass was performed. The postoperative course was uneventful, and the patient has been free of disease for 28 months. Trimodality therapy with use of a cardiovascular surgical procedure might be a valuable option in locally advanced thymic carcinoma., (Copyright © 2016 The Society of Thoracic Surgeons.

Inferior vena cava leiomyosarcoma is a rare tumor with a variety of symptoms. A 41-year-old woman was admitted with nonspecific epigastric pain. Computed tomography revealed a dense mass between the inferior vena cava and the liver. The patient underwent successful resection of the mass. The pathologic study confirmed leiomyosarcoma. Adjuvant radiation therapy was completed, and after 12 months of follow-up, the patient had no problems., (© The Author(s) 2014.)

The inferior vena cava (IVC) is the most common site of leiomyosarcomas arising from a vascular origin. Leiomyosarcomas of the IVC are categorized by anatomical location. Zone I refers to the infrarenal portion of the IVC, Zone II from the hepatic veins to the renal veins, and Zone III from the right atrium to the hepatic veins. This is a rare presentation of a Zone I-III leiomyosarcoma. Fifty-two-years-old female with a medical history significant only for HTN was admitted to the hospital with bilateral lower extremity edema and dyspnea. Two-dimensional echo demonstrated a right atrial thrombus, extending into the IVC. On subsequent CT and MRI, a 15 cm mass was noted that began in the right atrium and extended into the IVC, with continuation below the renal veins to above the level of the confluence of the common iliac veins. The patient underwent a complete resection of the mass, replacement of the IVC with Dacron graft, total hepatectomy and bilateral nephrectomy, with liver and kidney autotransplantation. Pathology was consistent with a high grade spindle cell sarcoma of vena cava origin. Patient was readmitted approximately 4 weeks postoperatively to begin adjuvant chemotherapy. This case represents a zone I-III IVC leiomyosarcoma treated with surgical R0 resection. This included a hepatectomy, bilateral nephrectomy, and hepatic and left renal autotransplantation. These complex tumors should be treated with surgical resection, and require a multidisciplinary approach., (© 2015 Wiley Periodicals, Inc.)

Unlabelled: Progredient tumor-growth does not mean necessarily nihilism since (because of the latest multimodal therapeutic options) it might be possible to convert the malignant disease into a chronic stage depending on tumor entity, specific tumor-associated findings and expertise of the interdisciplinary oncological/oncosurgical team to utilize available and potential therapeutic measures. The aim of this report on an unusual case (with its patient-associated, therapeutic and prognostic aspects) of a leiomyosarcoma of the inferior vena cava with advanced tumor growth (characterized initially by pulmonary and hepatic, later on by additional vertebral metastases) is to illustrate its changeful clinical course after and during multimodal treatment episodes comprising surgical (abdomino-/vascular-/cardio- and neurosurgical-locally, R0 resection status), radiological and chemotherapeutic measures. A relatively stable disease over a specific time period of 5 years and 6 months was achieved. The 54-year old female patient with metastasized leiomyosarcoma of the inferior vena cava underwent local tumor resection en bloc with inferior vena cava segmental resection (following vascular surgical interposition of a prosthesis) and hemihepatectomy as well as resection of hepatic segment I. After recovery, a multistep and -modal treatment was initiated comprising of various protocols of systemic chemotherapy, thermoablation of recurrent hepatic metastases, various brachytherapy procedures (for hepatic and pulmonary metastases) and resection of a cerebral metastasis by a neurosurgeon including subsequent radiation., Conclusions: The patient demonstrates impressively that even in case of advanced tumor stage with initial, novel and recurrent metastases, a relatively stable disease over an intermediate time period (of more than 5 years) with an acceptable quality of life was achieved despite several complications.

Background: Approximately 300 cases of leiomyosarcoma of the inferior vena cava (IVC) have been reported in the literature to date. In this study, we combined the experience from 2 institutions to provide additional clinical outcomes data., Methods: We performed a retrospective analysis from 1984 to 2009 that included 17 patients treated between the 2 institutions. Clinicopathologic data, surgical and adjuvant therapy, and survival outcomes were obtained., Results: The median age of patients in the study was 48 years. The tumor location was infrarenal in 8 patients, juxtarenal in 6, and suprahepatic in 2 patients; 7 patients had high-grade tumors. All patients underwent complete resection; the IVC was repaired primarily in 5 patients, ligated in 5, and reconstructed with a prosthetic tube graft in 7 patients. There was no perioperative mortality; 6 patients had complications. Median follow-up was 49 months; median survival had not been reached when this paper was written. The 5-year overall and disease -free survival were 56% and 37%, respectively. Of the 17 patients, 10 experienced disease recurrence and underwent numerous treatment modalities for these recurrences., Conclusion: Aggressive resection of primary leiomyosarcoma of the IVC can be performed safely and result in long-term survival, irrespective of IVC management. Despite high recurrence rates, no consensus yet exists regarding adjuvant treatment., (Copyright © 2012 Mosby, Inc. All rights reserved.)

Background: Leiomysarcoma of intravascular origin is an exceedingly rare entity of malignant soft tissue tumors. They are most frequently encountered in the retroperitoneum arising from the inferior vena cava and are scarcely found to arise from vessels of the extremities. These tumors were analysed with particular reference to treatment outcome and prognosis. The aim of this article is to broaden the knowledge of the clinical course of this rare malignancy., Method: During 2000 and 2009 twelve patients were identified with an intravascular origin of a leiomyosarcoma. Details regarding the clinical course, follow-up and outcome were assessed with focus on patient survival, tumor relapse and metastases and treatment outcome. 3 year survival probability was calculated using Kaplan-Meier method., Results: Vascular leiomyosarcomas accounted for 0.7% of all malignant soft tissue tumors treated at our soft tissue sarcoma reference center. The mean follow up period was 38 months. Tumor relapse was encountered in six patients. 6 patients developed metastatic disease. The three year survival was 57%., Conclusion: Vascular leiomysarcoma is a rare but aggressive tumor entity with a high rate of local recurrence and metastasis.

Case Report: pLMS in the wall of the inferior vena cava is an extremely rare form of retroperitoneal malignancies. A case in a young female patient is presented; clinical symptoms, pre- and postoperative diagnosis and surgical treatment are discussed. A retroperitoneal mass detected by imaging was found to be a large tumor mass located at the middle segment of the IVC on exploration. The tumour was successfully excised and the IVC was reconstructed with a synthetic graft. Eight years later, this patient needed a repeat surgery due to local recurrence. This time tumour was attached to the left renal vein. A re-resection of the IVC was performed with subsequent synthetic graft reconstruction and the distal end of the left renal vein was reimplanted into a lower segment of IVC., Discussion: Primary leiomyosarcoma of the inferior vena cava (pLMS-IVC) is an extremely rare form of retroperitoneal malignancies. The tumour arises from the medial layer of the venous wall and can grow either intraluminally, or extraluminally or in both directions, as well. It can be localized in the first segment of IVC (above the hepatic veins), in the second segment between hepatic and renal veins and finally in the third segment between the right common iliac vein and renal veins. Therefore, the tumour can infiltrate both hepatic and/or renal vessels. Upper segment tumours can cause Budd-Chiari syndrome (hepatomegaly, abdominal pain, jaundice and ascites) with a bad prognosis. Middle segment tumours usually present with right upper quadrant pain, or may mimic biliary tract disease with a much better prognosis. Accumulating experience suggests that radio-chemotherapy alone seems to be less effective than "en bloc" resection with clear margins including loco-regional lymph nodes. Therefore, our choice of treatment was the latter. Although radical resection can be carried out in most of cases, 50% of patients develop a late recurrence yet.

Background: Leiomyosarcoma (LMS) of the inferior vena cava (IVC) is exceedingly rare. The role of adjuvant therapy remains undefined. This study evaluated outcomes after aggressive management., Methods: Records on 20 patients undergoing surgery for IVC LMS between January 1990 and April 2006 were retrieved. Histology was confirmed upon re-review. Most patients received perioperative chemotherapy (CT), radiation therapy (RT), or both (CRT). Disease-free and overall survival (DFS, OS) rates were calculated using the Kaplan-Meier method., Results: Twenty patients (60% women, median age 57 years) with primary IVC LMS were treated with curative intent. Median follow-up was 41 months. All patients underwent resection of the primary tumor; one was found to have unresectable liver metastases. The IVC was managed with ligation (3), primary repair (12), or prosthetic graft (5). Additional organs were resected in 14 (70%) patients. Chemotherapy and/or RT were administered to 9 (45%) patients preoperatively (CT 2, RT 6, CRT 1) and 8 (40%) postoperatively (CT 4, RT 1, CRT 3). Median DFS was 21 months. Of 13 (68%) patients who developed recurrence, 4 underwent surgery, and 11 received CT. Median OS for 19 patients who underwent complete resection was 71 months. Tumor size was associated with disease recurrence (P = .004). No variables were prognostic for OS., Conclusions: Patients with IVC LMS treated with curative intent develop early recurrent disease. Nevertheless, long-term OS can be achieved even in the setting of metastatic disease. The independent impact of perioperative CT, RT, or CRT treatments cannot be adequately determined.

Surgical management of intracardiac tumors arising in the inferior vena cava often requires total circulatory arrest for safe and adequate resection. Total circulatory arrest has traditionally been accomplished by accessing the great vessels through a sternotomy. Combination of a sternotomy and a large abdominal incision results in excellent exposure but also creates the potential for significant morbidity. We report here the resection of cavoatrial tumors by achieving total circulatory arrest through femoral arterial and venous cannulation without requiring a sternotomy. This minimal-access total circulatory approach has the potential to greatly diminish morbidity when managing tumors of the inferior vena cava.

Intravenous leiomyoma with intracardiac extension is a rare entity that necessitates surgical excision to alleviate symptoms and prevent life-threatening complications. These procedures are generally performed under cardiopulmonary bypass, and review of the literature reveals an evolution in management of this disease from 2-stage to single-stage procedures. We report the case of a 45-year-old woman with an intravenous leiomyoma with intracardiac extension after presenting with syncopal symptoms. The intravenous tumor and its supradiaphragmatic extension were ultimately resected via laparotomy without the need for cardiopulmonary bypass. Distal control was achieved by passing an occluding balloon catheter above the tumor through a venotomy with fluoroscopic guidance and echocardiography, thus enabling protected tumor extraction through the intra-abdominal inferior vena cava. In selected patients, we believe use of endovascular techniques combined with proper preoperative imaging can safely permit single-stage resection of these tumors via laparotomy without cardiopulmonary bypass.

Objective/methods: To present an additional case of leiomyosarcoma of the inferior vena cava and review the literature, with special reference to the etiology, diagnosis and treatment of this rare tumor., Results: The patient was submitted to radical surgery and short course radiotherapy. Twelve months thereafter, the patient is asymptomatic and disease-free., Conclusions: Leiomyosarcoma of the inferior vena cava is a rare and aggressive tumor. Treatment is by aggressive and radical surgery.

Leiomyosarcoma (LMS) of the inferior vena cava (IVC) is a rare vascular tumour, with about 200 cases reported since 1871. The Authors report a case of leiomyosarcoma of the suprarenal inferior vena cava preoperatively diagnosed by ultrasonography and computed tomography. A surgical resection and venous wall reconstruction was performed. Complete surgical resection with a tumour-free margin (1 cm) is the treatment of choice. Neoadjuvant therapy may be given to downsize the tumour and increase resectability rate. When complete resection is not possible, debulking combined with radiation therapy provides good palliation.

Background: Leiomyosarcoma of the inferior vena cava (IVC) is an uncommon tumor that many believe portends a poor prognosis compared with leiomyosarcoma with similar histology at other anatomic sites. Because of the limited international experience with this disease, the optimal management of these patients is unknown., Methods: From October 1978 to January 1997, 14 patients with leiomyosarcoma of the IVC were treated at the University of California-Los Angeles Medical Center. Wide resection was attempted in all patients. The characteristics of each patient were documented and compared with those of patients with leiomyosarcoma of the stomach (n = 13), small intestine (n = 18), retroperitoneum (n = 19), and uterus (n = 10) who were treated during the same time period., Results: Age, gender, tumor size, tumor grade, and lymph node status did not impact survival of patients with leiomyosarcoma of the IVC. Patients with positive surgical margins fared significantly worse (P < 0.03) compared with those who underwent complete resection. Radiation therapy diminished local recurrence and may improve median survival (6 months [n = 2] vs. 51 months [n = 12]) in this patient population. Patients who received combined chemotherapy and radiation lived longer than those who did not (P < 0.05). The 5-year cumulative survival rate (Kaplan-Meier method) was 53% for patients with leiomyosarcoma of the IVC, 47% for those with leiomyosarcoma of the stomach, 43% for those with leiomyosarcoma of the small intestine, 56% for those with leiomyosarcoma of the retroperitoneum, and 65% for those with leiomyosarcoma of the uterus., Conclusions: Despite having a tumor that originates from the IVC, patients with this tumor type can enjoy reasonably long term survival. It appears that these patients benefit from radiation therapy to control local disease. Survival of these patients is no worse than of patients with leiomyosarcomatous lesions of other origin. Aggressive surgical management combined with adjuvant therapy offers the best treatment for patients with leiomyosarcoma of the IVC.

We report a case of leiomyosarcoma of the lower segment of the inferior vena cava in a fifty nine year old man who presented with bilateral leg edema on physical exploration. Ultrasonography, computed tomography scan and intravenous urography demonstrated the existence of a retroperitoneal tumour. The tumour and the affected venous fragment were resected. Postoperative radiotherapy was given. The patient was re-operated on three years later because of extra-local recurrence. Two years later the patient is assymptomatic and without radiological evidence of recurrence and/ or metastasis.

We report a case of testicular carcinoma invading the inferior vena cava. Tumor invasion was diagnosed via endovascular biopsy. This is the first known report of a diagnosis of this entity using endovascular biopsy. We also review the literature on diagnosis and management of inferior vena caval involvement by testicular cancer.
