PURPOSE: To examine the perioperative outcomes following robot-assisted partial nephrectomy (RAPN) in patients with localized renal cell carcinoma (RCC) and to identify the predictors of Pentafecta achievement following RAPN. MATERIALS AND METHODS: We retrospectively analyzed the data from 362 patients with RCC who underwent RAPN from 2008 to 2016. The criteria for Pentafecta achievement was defined as the Trifecta [warm ischemia time (WIT) ≤ 25 minutes, negative surgical margin, and no significant perioperative complications]; with the addition of renal function preservation, including over 90% preservation of the estimated-glomerular filtration rate (e-GFR); and no stage upgrade of chronic kidney disease at 1 year after surgery...

BACKGROUND: Although numerous studies have been published on robotic adrenalectomy (RA) in the literature, none has done a comparison of posterior retroperitoneal (PR) and transabdominal lateral (TL) approaches. The aim of this study was to compare the outcomes of robotic PR and TL adrenalectomy. METHODS: This is a retrospective analysis of a prospectively maintained database. Between September 2008 and January 2017, perioperative outcomes of patients undergoing RA through PR and TL approaches were recorded into an IRB-approved database...

AIM: The purpose of this study was to evaluate the efficacy of en bloc nephrectomy for perirenal retroperitoneal sarcoma (RPS) with respect to postoperative kidney function and oncological benefits. METHODS: We performed a comparative study of 114 patients undergoing surgery for primary RPS, classifying cases as nephrectomy (NPX, n = 65) versus no nephrectomy (no-NPX, n = 49). The Δ and % change between preoperative and postoperative estimated glomerulus filtration rate (eGFR) were analyzed to compare renal function changes after surgery...

BACKGROUND: Malignant fibrous histiocytoma is a sarcoma of uncertain origin that can be found both in soft tissues and in bones. It is currently called undifferentiated pleomorphic sarcoma not otherwise specified and it represents a final common pathway in several tumors that are subject to the progress of dedifferentiation. Local recurrence of the tumor in the same location where it was originated occurs in 20-30% of the total number of soft tissue sarcomas. It is less frequent in limbs and more likely to recur in retroperitoneal sarcomas and in head and neck...

PURPOSE: While previously thought to be clinically indolent, recent data suggest significant late metastatic capacity of solitary fibrous tumors (SFTs). We define prognostic factors for recurrence and disease-specific death (DSD) in resected primary SFTs. METHODS: Resected primary SFTs from 1982 to 2015 were identified from a prospective, single institutional database. Risk factors for local (LR) and distant recurrence (DR), and DSD were assessed using competing risk analysis...

PURPOSE: While retroperitoneal lymph node dissection (RPLND) is traditionally reserved for nonseminomatous germ cell tumors, recent efforts to reduce long-term toxicities of radiation and chemotherapy have turned attention to its application for testicular seminomas. Currently, RPLND is reserved for the post-chemotherapy for stage II testicular seminomas; we aimed to describe current utilization of RPNLD for testicular seminomas by stage and implications for survival. METHODS: A national sample of men diagnosed with stage IA/IB/IS/IIA/IIB/IIC testicular seminoma (1988-2013) was evaluated from SEER Program registries...

Presacral ganglioneuromas are extremely rare benign tumors and fewer than 20 cases have been reported in the literature. Ganglioneuromas are difficult to be differentiated preoperatively from tumors such as schwannomas, meningiomas, and neurofibromas with imaging modalities. The retroperitoneal approach for resection of presacral ganglioneuroma was performed for gross total resection of the tumor. Recurrence and malignant transformation of these tumors is rare. Adjuvant chemotherapy or radiation therapy is not indicated because of their benign nature...

A 64-year-old female patient underwent radical left nephrectomy in 2005 after being diagnosed with renal cell carcinoma. The pathological diagnosis was pT2b pN0 M0 clear cell carcinoma. Three years postoperatively, metastatic recurrence in the para-aortic lymph node was noted, and the patient underwent retroperitoneal lymph node dissection in 2008. The pathological diagnosis was renal cell carcinoma (a combination of clear cell carcinoma and type 2 papillary cell carcinoma). Five years later, she exhibited splenic metastasis on computed tomography, but no other distant metastases were observed...

A 61-year-old man visited our hospital for treatment of a retroperitoneal tumor. The patient had undergone distal gastrectomy for gastric cancer in the past. At 5 years after distal gastrectomy, a retroperitoneal tumor with a large diameter of 30mm was detected by computed tomography and the patient underwent chemotherapy for suspected lymph node metastasis from gastric cancer at a local hospital. However, the retroperitoneal tumor gradually increased, and it was diagnosed finally as asymptomatic paraganglioma...

Malignant pheochromocytoma in children manifesting as local recurrence with multiple lymph nodal metastasis is a rare entity. We report a case of a 14-year-old child with recurrent sporadic malignant pheochromocytoma presenting 8 years after primary surgery with retroperitoneal lymphadenopathy. The child underwent excision of the tumor along with retroperitoneal lymphadenectomy. Histopathology confirmed pheochromocytoma with extensive lymph node metastasis. The patient has no signs of disease recurrence till date...

Metastatic primary testicular carcinoid tumor remains a very rare condition. We report the first case of metastatic primary testicular carcinoid tumor where along retroperitoneal lymph node dissection excision of the Inferior Vena Cava was also performed. The rarity is further emphasised by the presence of a contralateral testicular dermoid cyst. Given the features of the tumor were not in keeping with the traditional predictors of metastases (primary tumor >7.3 cm, poor differentiation and the presence of carcinoid syndrome) this case adds valuable addition to the relatively limited literature available on this rare condition...

PURPOSE: Prognosis of stage I NSGCTT is very favorable. Early and late side effects of treatment may condition quality of life and survival. We determine tolerability, safety and efficacy of L-RPLND in stage I NSGCTT in a high-volume center. PATIENTS AND METHODS: From 2000 and 2014, 225 patients undergoing unilateral L-RPLND were prospectively recorded. Since 2007 patients underwent multidisciplinary clinic and were proposed surgery as an alternative to surveillance or adjuvant chemotherapy...

Dedifferentiated liposarcoma is typically a nonlipogenic high-grade sarcoma that arises from well-differentiated liposarcoma. It most commonly presents as a large mass in the retroperitoneum. Significant involvement of the gastrointestinal tract by dedifferentiated liposarcoma is uncommon. We present a unique case of dedifferentiated liposarcoma radiographically mimicking a primary colon mass with resulting intussusception; stranding of the adjacent adipose tissue was presumed to be a secondary reactive change...

Ectopic pheochromocytoma (EP) is considered as pheochromocytoma located at extra-adrenal site. Surgical removal is believed to be the best choice for treatment of pheochromocytoma. We present a series EP resected by laparoscopic approach (LEP) and confirm its feasibility. We retrospectively reviewed clinical data of 4 patients underwent laparoscopic resection of LEP (periaortocaval EP, n = 1; retroperitoneal EP, n = 2; bladder EP, n = 1), which was collected and analyzed retrospectively in Zhejiang Provincial People's Hospital...

Aggressive angiomyxoma is a benign stromal tumor with a higher prevalence in middle-aged women. The objective of this case report is to illustrate the aggressive clinical behavior of this benign tumor. We present the case of a 45-year-old female patient, with tumor recurrence after multiple surgical resections of a pelvis-subperitoneal angiomyxoma. Surgical excision of the tumor, with extensive pelvic dissection and organ resection, was performed. The 12-month follow-up showed no tumor recurrence. Based on this case, and the published literature we may conclude that surgical resection represents the main treatment of aggressive angiomyxoma, even though it is associated with significant morbidity and a poor local control of the tumor...

BACKGROUND: Given the rarity of testicular germ cell tumors (TGCTs) and the complex aspects of management, we evaluate the effect of hospital TGCT case volume on overall survival outcomes and practice patterns. MATERIALS AND METHODS: The National Cancer Database was queried for patients diagnosed with seminoma or nonseminomatous germ cell tumor (NSGCT). Hospitals were classified by case volume as high (99th percentile, ≥26.1 cases annually), high-intermediate (95-99th percentile, 14...

Carney triad is a synchronous or metachronous association of gastric gastrointestinal stromal tumors (GIST), pulmonary chondroma and extra-adrenal paraganglioma. The majority of patients have only one or two components of the triad, all three tumors being found in only about 2% of the patients at the time of the first diagnosis. The most common combination is gastric and pulmonary tumors. We report a case of Carney triad which was diagnosed at Masaryk Memorial Cancer Institute. A 57-year-old female patient with a history of gastric resection for leiomyosarcoma at the age of 14 and with an unclear pulmonary lesion evident on chest X-ray since as early as 2003...

Benefit from chemotherapy for well-differentiated/de-differentiated (WD/DD) liposarcomas has been reported to be minimal, however traditional response criteria may not adequately capture positive treatment effect. In this study, we evaluate benefit from first-line chemotherapy and characterize imaging response characteristics in patients with retroperitoneal (RP) WD/DD liposarcoma treated at The University of Texas MD Anderson Cancer Center. Response was assessed using RECIST (Response Evaluation Criteria in Solid Tumors) and an exploratory analysis of vascular response was characterized...
