Surgical outcomes for older patients with renal cell carcinoma and inferior vena cava thrombus

ObjectivesTo compare the surgical and oncological outcomes of older patients undergoing surgery for renal cell carcinoma (RCC) with a tumor in the inferior vena cava (IVC) and those of younger patients.Materials and methodsWe retrospectively evaluated 123 patients who underwent surgery for RCC-IVC at two institutions between 2008 and 2019. We classified them into the ≥70 years and the <70 years group, based on their age during surgery. The patients’ perioperative outcomes as well as survival (overall survival [OS] and cancer-specific survival [CSS]) were evaluated and compared before and after 1:1 propensity score matching. Sensitivity analyses were performed at age thresholds of 75 and 80 years.ResultsThe ≥70 and the <70 groups comprised 43 and 80 patients, respectively. Most patients in the ≥70 group demonstrated an American Society of Anesthesiologists score of 2 or 3. They were more likely to have a statistically insignificant high (≥3) Charlson Comorbidity index score (16.3 vs. 6.3%) and a lower hemoglobin level (10.4 vs. 11.7 g/dL) than the <70 group. Eighteen (41.9%) and 32 (40.0%) patients had at least one distant metastasis at the time of surgery in the ≥70 and <70 group, respectively. The complication rates (any grade and grade ≥3), the length of hospitalization, readmission rates, and mortality were comparable between the groups, both before and after matching (all, non-specific). There was no statistically significant difference in the OS (median 66.6 vs. not reached [N.R.], P = 0.695) or CSS (N.R. vs. N.R., P = 0.605) between the groups before matching. The OS and CSS results were similar and comparable following matching (both, non-specific). Further, OS and CSS were comparable between the ≥75 and <75 groups, and between the ≥80 and <80 age groups, respectively.ConclusionThe surgical outcomes of older patients with RCC-IVC were not inferior to those of younger patients. With careful patient selection, surgery can still be a treatment option.     

Surgical treatment of retroperitoneal leiomyosarcoma invading the inferior vena cava: report of three cases

Retroperitoneal leiomyosarcoma is a rare neoplasm for which complete surgical removal provides the only effective treatment, as local recurrence adversely affects prognosis. However, invasion of major vessels may occur, making complete resection difficult. This report describes the cases of three patients who required concomitant resection of parts of the inferior vena cava because of direct tumor invasion. The major vessels should be isolated in preference to the tumor capsule during surgery to prevent sudden exsanguination or incomplete tumor resection. Resection of a recurrent sarcoma or a solitary metastasis can be effective in selected patients. Received: September 20, 2001 / Accepted: May 7, 2002     

Surgical treatment of thrombosis of the inferior vena cava

Personal experience of thromboses of the inferior vena cava is presented and pathogenetic and symptomatological aspects stressed. In addition, in relation to the results presented and reported data, it is concluded that the role of surgical therapy is fundamental to integrate the thrombolytic and anticoagulant treatment of these severe forms of deep venous thrombosis.     

累及下腔静脉的腹膜后肿瘤手术处理经验

目的探讨累及下腔静脉的腹膜后肿瘤手术时下腔静脉的处理方法 ,以提高切除率及手术安全性。方法回顾性分析 1990年 1月至 2 0 0 3年 4月收治的 4 1例腹膜后肿瘤累及下腔静脉的手术切除及血管重建的临床资料。结果 4 1例累及下腔静脉的腹膜后肿瘤的手术方式有 :下腔静脉部分切除、修补术 17例 ;部分下腔静脉并右肾切除术 11例 ;部分下腔静脉切除、残端结扎术 10例 ,其中 3例行人工血管植入术。结论B超、CT、MRI是术前必不可少的检查 ,选择性血管造影可以明确下腔静脉受压、移位、畸形及有无闭塞。累及下腔静脉并非腹膜后肿瘤行根治性切除的手术禁忌证 ,下腔静脉部分切除与重建安全、有效、可行 ,可以大大提高肿瘤的切除率、降低复发率。     

An unusual case of leiomyosarcoma of the inferior vena cava in a patient with a duplicated inferior vena cava

Leiomyosarcoma of primary vascular origin is a rare primary soft tissue tumour, which arises mainly from the inferior vena cava (IVC). Clinical symptoms depend upon the size and location of the tumour and presents usually with abdominal pain, palpable mass and weight loss. Complete surgical resection with clear surgical margin plays a central therapeutic role. The effect of chemotherapy and radiation therapy remains to be evaluated. We report a 64 year old Chinese female who presented with abdominal mass and pain associated with weight loss and was subsequently diagnosed with inferior vena cava leiomyosarcoma. She underwent successful surgical resection but unfortunately developed recurrence of tumour 12 month post-operative. She was also found to have a duplicated inferior vena cave which allowed reconstitution of venous return from the lower limbs after surgical resection of the IVC tumour. We discuss the surgical treatment and results of leiomyosarcoma of the IVC.     

A case of leiomyosarcoma of the inferior vena cava

Primary leiomyosarcoma of the inferior vena cava is rare and fatal. A 15-year-old female was admitted with the diagnosis of the right atrial myxoma associated with the Budd-Chiari syndrome. The tumor of the IVC was unresectable, although the right atrial tumor extended from the IVC was extirpated. Pathological examination of the tumor revealed a leiomyosarcoma. She was hemodynamically improved immediately after the operation. But she was expired due to the hepatic failure 9 days postoperatively. No autopsy was obtained. The literature regarding with leiomyosarcoma of the IVC was briefly reviewed.     

A case of leiomyosarcoma of the inferior vena cava

A case of primary leiomyosarcoma of the inferior vena cava was reported. The patient, a 74-year-old man, consulted our hospital with complaints of back pain and abdominal mass in right flank. Probe laparotomy revealed a tumor situated in the retroperitoneum and multiple metastatic nodules in the liver. Biopsy was performed and diagnosed as leiomyosarcoma. He was intensively treated with antineoplastic chemotherapy, but his condition gradually aggravated. He died 4 months after admission. The autopsy revealed a right retroperitoneal mass (17 X 12 X 18 cm in size, 1,340 g in weight) that showed a yellowish appearance. There was also a thumb-tip sized tumor with a stalk in the lumen of inferior vena cava. Both tumors grew in continuity with each other through the wall of inferior vena cava. The tumors were diagnosed as leiomyosarcoma, which derived from inferior vena cava.

Primary leiomyosarcoma of inferior vena cava: Case report

An intramural venous leiomyosarcoma is a rare, malignant tumour arising from the smooth muscle cells of the vessel wall and the inferior vena cava (IVC) is the most common location. The middle part of IVC is most often affected, often involving the kidneys. There is a strong prediction for women. Clinical symptoms depend upon the size and location of the tumour. Diagnosis is often not made until advanced stage, as the symptoms are non-specific and they present late in the disease course.
