Abstract
BACKGROUND AND OBJECTIVES Surgical resection of retroperitoneal sarcomas (RPS) often involves removal of the ipsilateral kidney. We evaluated the long-term post-operative renal function in patients who underwent a nephrectomy as part of their en-bloc resection of RPS. METHODS Retrospective review of an institutional database identified RPS patients who underwent nephrectomy for curative intent from 1990 to 2014. The primary outcome measured was chronic kidney disease (CKD) calculated by the glomerular filtration rate (GFR). RESULTS Of the 47 patients in our study, 19 (40%), 18 (38%), and 10 (21%) patients had a preoperative CKD stage 1, 2, and 3, respectively. The GFR decreased by an average of 33.4 mL/min/1.73 m2 with 66% of patients demonstrating mild progression of their renal impairment. Only three (6%) patients progressed to CKD stage 4 or 5, one of which required life-long dialysis. CONCLUSION Nephrectomy as part of an en-bloc resection is associated with a decrease in GFR that is not clinically significant. Fear of kidney failure should not prevent a surgeon from performing a nephrectomy in the treatment of RPS.

Abstract
BACKGROUND Operative resection remains the definitive curative therapy for retroperitoneal sarcoma. Data published recently show a correlation between improved outcomes for complex oncologic operations and treatment at academic centers. For large retroperitoneal sarcomas, operative resection can be complex and require multidisciplinary care. We hypothesized that survival rates vary between type of treating center for patients undergoing resection for retroperitoneal sarcoma. METHODS Patients with stage I to III nonmetastatic retroperitoneal sarcomas who underwent operative resection were identified from the National Cancer Database during the years 2004-2013. Treating centers were categorized as academic cancer centers or community cancer centers. Overall survival was analyzed by log-rank test and graphed using Kaplan-Meier method. RESULTS A total of 2,762 patients were identified. A majority of patients (59.4%, n = 1,642) underwent resection at an academic cancer centers. Median age at diagnosis was 63 years old. Neoadjuvant radiotherapy was more common at academic cancer centers, while adjuvant radiotherapy was more common at community cancer centers. Improved overall survival was seen at academic cancer centers across all stages compared with community cancer centers (P = .014) but, after multivariable Cox regression analysis, was not a significant independent predictor of survival (hazard ratio = 0.91, 95% confidence interval, 0.79-1.04, P = .171). Academic cancer centers exhibited a greater rate of R0 resection (55.9% vs 47.0%, P < .001) and a lesser odds of positive margins (odds ratio 0.83, 95% confidence interval, 0.69-0.99, P = .044) after multivariable logistic regression. CONCLUSION Resection for retroperitoneal sarcoma performed at academic cancer centers was an independent predictor of margin-negative resection but was not a statistically significant factor for survival. This observation suggests that site of care may contribute to some aspect of improved oncologic resection for retroperitoneal sarcoma.

Abstract
PURPOSE OF REVIEW Recent developments of neo-adjuvant chemotherapy treatment strategies for high-risk soft tissue sarcoma (STS) with special emphasis on regional hyperthermia (RHT) are reviewed. RECENT FINDINGS Attempts to improve outcomes using up-front strategies in addition to surgery have essentially focused on neo-adjuvant and adjuvant chemotherapy or preoperative radiochemotherapy. Unfortunately, the results are either confounded by retrospective analyses of nonrandomized studies with small sample size or are negative showing no substantial clinical benefit in the few randomized trials. RHT targets the region of tumor burden by heat. The pleotropic effects on malignant cells and tumor stroma to counteract tumor growth and progression have been recently summarized as hallmarks of hyperthermia. An updated analysis of a completed EORTC-ESHO Intergroup randomized phase 3 trial for the most common types of high-risk STS demonstrates a significantly improved long-term overall survival for patients receiving RHT in combination with neo-adjuvant chemotherapy added to standard surgery and postoperative radiation. SUMMARY By comparison with other strategies, RHT combined with preoperative and postoperative chemotherapy improves overall survival and adds an important but underused standard for high-risk STS.

Abstract
INTRODUCTION The purpose of this article was established by the external genitalia group CCAFU recommandations for diagnosis, treatment and monitoring of retroperitoneal sarcomas, intended for urologists. MATERIAL AND METHODS The multidisciplinary working group has updated the 2013 guidelines, based on an exhaustive review of the literature on PubMed, valued references, level of evidence, to assign grades of recommendation. RESULTS From a clinical suspicion evoking a RPS, computed tomography thoraco abdominal and pelvic is the gold standard. MRI is useful for surgical planning. Before the biopsy confirmation, the inclusion of the file in the French sarcoma pathology reference network should be the rule. The biopsy under scanner performed by retroperitoneal approach is recommended and should be achieve before any therapeutic management of a suspicious retroperitoneal solid mass. Treatment is primarily surgical with the main objective resection in healthy margins (R0) obtained by a technically challenging compartmental resection surgery. Instead of radiation therapy and chemotherapy within a multimodal treatment (neo adjuvant or adjuvant) is discussed based on the evolving risks and opportunities excision. The relapse rate is related to tumor grade and surgical margin. The final prognosis is closely related to the quality of initial management and the volume of cases handled by the center. CONCLUSION The RPS has a poor prognosis. The quality of the initial management directly impacts the disease-free survival and overall survival. The multidisciplinary management coordinated within a referent care network of sarcoma pathology is an imperative necessity. © 2016 Elsevier Masson SAS. All rights reserved.

Abstract
BACKGROUND Optimal treatment strategies for retroperitoneal leiomyosarcoma (RPLMS), particularly recurrent disease, are unknown. METHODS We searched the tumor registry at The University of Texas MD Anderson Cancer Center (MDACC) to identify patients with RPLMS treated between 1994 and 2013. RESULTS We identified 172 patients with a diagnosis of a RPLMS. Among the 85 patients who underwent complete resection included in the survival analysis, the median overall survival (OS) was 8.3 years (95% confidence interval [CI], 5.7-12.3), 5-year local recurrence rate was 21%, and 5-year distant metastasis rate was 47%. Among 114 patients who experienced recurrence, patients who underwent salvage surgery for recurrent disease had longer OS after recurrence than patients who did not undergo salvage surgery (median survival after recurrence 5.6 vs 3.3 years, 3-year OS rates after recurrence 72.6% vs 58.1%, HR 0.402 [95%CI, 0.243-0.666]; P = 0.0004). Whether salvage surgery was performed for local or distant recurrence was not associated with OS. Patients who had a longer disease-free interval (≥12 months) had better progression-free survival after salvage surgery than those who had a shorter interval (HR, 0.437 [95%CI, 0.244-0.783]; P = 0.0055). CONCLUSIONS We recommend that salvage surgery be considered for selected patients with local or distant recurrence of RP LMS.

Contemporary reappraisal of the efficacy of adjuvant chemotherapy in resected retroperitoneal sarcoma: Evidence from a nationwide clinical oncology database and review of the literature. Surg Oncol 2017; 26:117-124. [PMID: 28577717 DOI: 10.1016/j.suronc.2017.01.008] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2016] [Revised: 01/23/2017] [Accepted: 01/31/2017] [Indexed: 11/30/2022]
Abstract
BACKGROUND While margin-negative resection remains the cornerstone of therapy for retroperitoneal sarcoma (RPS), the impact of adjuvant chemotherapy (AC) on overall survival (OS) remains poorly understood. METHODS The National Cancer Data Base was queried for patients undergoing curative-intent resection of primary non-metastatic RPS (2004-2013). Multivariable modeling identified factors associated with AC receipt. Cox regression identified covariates associated with OS, and AC and surgery alone (SA) cohorts were matched 1:1 by propensity scores based on these covariates. In the propensity-score matched cohort, OS was compared by Kaplan-Meier estimates. Results from this analysis were presented in the context of a review of the existing literature on the impact of AC in resected RPS. RESULTS Of 3892 resected RPS patients, 90.0% and 10.0% received SA and AC, respectively. Predictors of AC receipt included younger age, non-Caucasian race, hospital location, histologic grade, adjacent organ invasion, and histologic subtype. The propensity score-matched cohort comprised 767 patients (SA n = 377; AC n = 390); at a median follow-up of 59.2 (IQR 35.0-85.3) months, median OS of the propensity-matched cohort was 53.6 (IQR 22.4-119.5) months. Utilization of AC was associated with significantly worse long-term survival (median OS: 47.8 vs. 68.9 months, p = 0.017; HR 1.30, 95% CI 1.05-1.61). AC was not associated with improved OS in margin-positive (R1/R2) resection, high-grade (G2/G3) and larger (>10 cm) tumors, or in any histologic subtype. Albeit not statistically significant, there was a trend toward improved OS with AC in spindle cell (HR 0.37, 95% CI 0.10-1.38), giant cell (HR 0.82, 95% CI 0.32-2.13), and synovial (HR 0.26, 95% CI 0.05-1.33) sarcoma. CONCLUSIONS Data from a large nationwide oncology database and review of the existing literature do not support adjuvant chemotherapy regimens following curative-intent resection of RPS, even in subgroups at high risk of failure (e.g., R1/R2 resection, high-grade or large tumors). The possible benefit of conventional adjuvant regimens in spindle cell, giant cell, and synovial sarcoma should be explored in prospective studies.

Abstract
Retroperitoneal sarcomas are rare tumors, representing only 15% of all sarcomas. The mainstay of therapy is surgical resection with negative margins. However, this is challenging because of the late presentation of many of these tumors and involvement with adjacent structures. Decisions on radiation therapy and chemotherapy should be made in a multidisciplinary setting at a tertiary referral center.

Abstract
PURPOSE To conduct phase 1 and 2 trials with photon intensity modulated radiation therapy and intensity modulated proton therapy (IMPT) arms to selectively escalate the retroperitoneal sarcoma preoperative radiation dose to tumor volume (clinical target volume [CTV] 2) that is judged to be at a high risk for positive margins and aim to reduce local recurrence. We report on the IMPT study arm in phase 1. METHODS AND MATERIALS Patients aged ≥18 years with primary or locally recurrent retroperitoneal sarcoma were treated with preoperative IMPT, 50.4 GyRBE in 28 fractions, to CTV1 (gross tumor volume and adjacent tissues at risk of subclinical disease) with a simultaneous integrated boost to CTV2 to doses of 60.2, 61.6, and 63.0 GyRBE in 28 fractions of 2.15, 2.20, and 2.25 GyRBE, respectively. The primary objective of the phase 1 study was to determine the maximum tolerated dose to CTV2, which will be further tested in the phase 2 study. RESULTS Eleven patients showed increasing IMPT dose levels without acute dose limiting toxicities that prevented dose escalation to maximum tolerated dose. Acute toxicity was generally mild with no radiation interruptions. No unexpected perioperative morbidity was noted. Eight months postoperatively, one patient developed hydronephrosis that was treated by stent with ureter dissected off tumor and received 57.5 GyRBE. Retained ureter(s) was (were) subsequently constrained to 50.4 GyRBE without further problem. With an 18-month median follow-up, there were no local recurrences. CONCLUSIONS IMPT dose escalation to CTV2 to 63 GyRBE was achieved without acute dose limiting toxicities. The phase 2 study of IMPT will accrue patients to that dose. Parallel intensity modulated radiation therapy phase 1 arm is currently accruing at the initial dose level. Ureters that undergo a high dose radiation and/or surgery are at risk for late hydro-ureter. Future studies will constrain retained ureters to 50.4 GyRBE to avoid ureteral stricture.

Abstract
Sarcomas are a heterogeneous group of mesenchymal tumors arising from soft tissue or bone, with an uncertain etiology and difficult classification. Soft tissue sarcomas (STSs) account for around 1% of all adult cancers. Till date, more than 50 histologic subtypes have been identified. Adipocyte sarcoma or liposarcoma (LPS) is one of the most common STS subtypes, accounting for 15% of all sarcomas, with an incidence of 24% of all extremity STSs and 45% of all retroperitoneal STSs. The new World Health Organization classification system has divided LPS into four different subgroups: atypical lipomatous tumor/well-differentiated LPS, dedifferentiated LPS, myxoid LPS, and pleomorphic LPS. These lesions can develop at any location and exhibit different aggressive potentials reflecting their morphologic diversity and clinical behavior. Patients affected by LPS should be managed in specialized multidisciplinary cancer centers. Whereas surgical resection is the mainstay of treatment for localized disease, the benefits of adjuvant and neoadjuvant chemotherapy are still unclear. Systemic treatment, particularly chemotherapy, is still limited in metastatic disease. Despite the efforts toward a better understanding of the biology of LPS, the outcome of advanced and metastatic patients remains poor. The advent of targeted therapies may lead to an improvement of treatment options and clinical outcomes. A larger patient enrollment into translational and clinical studies will help increase the knowledge of the biological behavior of LPSs, test new drugs, and introduce new methodological studies, that is, on treatment response.

Abstract
BACKGROUND Retroperitoneal tumors are rare malignancies. The retroperitoneum can host a wide spectrum of pathologies including primary or metastatic lesions. OBJECTIVE Treatment of retroperitoneal tumors is often associated with several challenges because of their relative late presentation and anatomic location. MATERIALS AND METHODS Because of various pathologies, a detailed case history, laboratory investigation and ultrasound should be performed. Radiologic examinations remain a major component in the diagnosis. In addition to computed tomography, magnetic resonance imaging and positron emission tomography are used. Although radiologic findings are often unspecific, there are often typical findings such as dissemination, margins, vascularization and tumor texture which contribute to the differential diagnosis even before making a definitive diagnosis. Due to the complexity of primary retroperitoneal tumors, which require different treatments depending on the final diagnosis, the treatment approach should be determined in a multidisciplinary tumor conference prior to histological confirmation and initiation of treatment. CONCLUSION To ensure the best potential curative treatment modality for retroperitoneal tumors, treatment is best performed in high-volume centers by a multidisciplinary team.

Abstract
Sarcomas are a heterogeneous group of rare tumors that originate from mesenchymal tissue. Radical R0 resection is the only curative option, which is especially challenging in retroperitoneal or intra-abdominal sarcomas. This article describes the current data on optimal interdisciplinary and primarily surgical therapy of visceral sarcomas. Surgical resection of retroperitoneal sarcomas must be performed according to the principle of radical compartmental resection, i.e. with complete excision of the mass along with en bloc visceral resection of adjacent organs and tissues covering the tumor, which also contains any not obviously infiltrated neighboring organs. The main objective is R0 resection without opening the tumor capsule in the primary operation because the best long-term results can be achieved with this approach.

Abstract
Due to optimization of surgical techniques in surgical oncology and vascular surgery, the most modern approaches of anesthesia and intensive care medicine and effective multimodal therapeutic strategies, locally advanced malignant tumors are resected more frequently with a potentially curative intent. In the case of extensive tumors with infiltration of vital vascular structures or of structures which are crucial for extremity preservation, the necessary surgical procedure for complete tumor removal poses a major challenge for the surgeon and incorporates a high risk of perioperative morbidity for the patient. The decision to attempt tumor resection should therefore always be based on a concept considering all aspects of the malignant disease. The treating team should be highly experienced in this complex field of surgery, not only with respect to the surgical approach but also regarding the management of postoperative complications. In this article relevant aspects of decision making, surgical technique and postoperative outcome for malignant tumors involving vascular structures of the retroperitoneum and pelvis are presented.
