Khan M, Wilkerson H, Vassos N, Hannay JA, Thway K, Messiou C, Hayes AJ, Strauss DC, Smith MJ. Oncologic outcomes of surgically managed primary pelvic soft tissue sarcoma; tumour biology or surgical constraints of the true pelvis? EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2022; 49:941-949. [PMID: 36566120 DOI: 10.1016/j.ejso.2022.12.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2022] [Revised: 12/06/2022] [Accepted: 12/14/2022] [Indexed: 12/23/2022]
Abstract
BACKGROUND Pelvic soft tissue sarcomas are rare. Potentially curative resection remains challenging due to anatomical constraints of true pelvis and tumour spread through various anatomical hiatus. We sought to review the oncological outcomes of surgically managed cases at our centre and determine whether outcomes differ for patients with localised (limited to pelvis) versus extensive disease (with extra-pelvic extension). METHODS Sixty-seven patients who underwent surgical resection with curative intent at the centre for primary, non-metastatic, WHO intermediate to high-grade soft tissue sarcoma of the true pelvis from January 2012 through January 2020 were analysed. Establishment of the extent of disease was made by review of pre-treatment imaging and surgical notes. Oncologic endpoints examined were resection margin, recurrence rate, disease-free and overall survival. RESULTS Rates of complete oncological resection and disease control were similar for tumours with localised or extensive disease. On logistic regression analysis, tumour grade, and a negative resection margin (R0) correlated with the risk of recurrence (p=<0.05). On further multinomial analysis, R0 resection was associated with improved local control, but not metastatic relapse (p = 0.003). 5-year local recurrence-free and distant metastasis-free survival were 61.3% and 67.1%, respectively. Five and 10-year overall survival were 64% and 36%, respectively. Age >50 years and high tumour grade were associated with a worse outcome (p < 0.05). CONCLUSIONS When potentially curative surgery is performed for pelvic sarcoma, disease-extent does not influence oncologic outcomes. While a complete oncologic resection determines the risk of local recurrence, tumour grade and metastatic relapse remain primary prognostic determinants for overall survival.

Abstract
Retroperitoneal and pelvis sarcomas are uncommon tumors for which complete surgical resection is the mainstay of treatment. However, achieving complete gross resection with microscopically negative margins is challenging, and local recurrence rates can be high. Patients often succumb to uncontrolled local disease. Radiation therapy offers a potential means for sterilizing microscopic residual disease, although its use continues to be controversial. Chemotherapy alone or in combination with radiation continues to be investigated as an adjunct to surgery, along with immunotherapy and targeted therapies. In this review, we discuss the current management of retroperitoneal and pelvis sarcomas, focusing on studies of surgery and radiation therapy to maximize local control.

Abstract
BACKGROUND AND PURPOSE Locoregional recurrence after resection of primary retroperitoneal sarcoma (RPS) is a challenging therapeutic issue. The objective of this study was to identify clinicopathological factors predictive of overall survival (OS) and disease specific survival (DSS) after reoperation for recurrent RPS. PATIENTS AND METHODS We retrospectively collected data from the medical records of 800 patients who underwent resection for sarcoma at our Institution, from 1983 to 2015. Among these patients, 120 were treated for retroperitoneal sarcoma and 55 had a locoregional recurrence (LR). Four of them did not undergo surgery and thus were excluded from this study leaving 51 cases available for data analysis. Univariate and multivariate survival analyses were performed to identify prognostic factors. RESULTS Median overall survival was 33 months. The 1-year, 3-year and 5-year OS rates were 75.5%, 47.1% and 31.6% respectively. Multivariate Cox regression analysis suggested that extension of surgery (P = 0.026), surgical margin status (P = 0.015) and histological grade of recurrent tumor (P = 0.047) were independent prognostic factors for OS. Median DSS was 48 months. The 1-year, 3-year and 5-year DSS rates were 79.2%, 53.1% and 40.9%, respectively. At multivariate analysis, predictors of DSS were extension of surgery (P = 0.004), margin status (P = 0.011), histological grade of recurrent tumor (P = 0.008), and disease free interval (DFI) (P = 0.020). As regards histological subtype of recurrent RPS, at univariate analysis, well-differentiated liposarcoma (WDLS) was associated with better OS and DSS (P = 0.052 and P = 0.016 respectively) compared to dedifferentiated liposarcoma (DDLS). CONCLUSIONS According to our findings, surgery is more beneficial in patients with low-grade sarcoma, WDLS and long DFI. The achievement of clear resection margins, rather than performing a multivisceral resection, appears to be a key factor to improve OS and DSS.

J Vasc Interv Radiol 2016; 27:1798-1805. [PMID: 27617909 DOI: 10.1016/j.jvir.2016.06.034] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2016] [Revised: 06/16/2016] [Accepted: 06/27/2016] [Indexed: 02/07/2023] Open
Abstract
PURPOSE To evaluate the pain-alleviating effect of computed tomography (CT)-guided percutaneous cryoablation for recurrent retroperitoneal soft-tissue sarcomas (RPSs). MATERIALS AND METHODS Data from 19 men and 20 women (median age, 50.3 y) with recurrent malignant RPS who underwent percutaneous cryoablation were reviewed retrospectively. A total of 50 tumors were treated by cryoablation, including a single tumor in 29 patients, 2 tumors in 9, and 3 tumors in 1. Adverse events and analgesic outcomes were compared as a function of tumor size (< 10 cm and ≥ 10 cm). Efficacy was assessed based on modified Response Evaluation Criteria In Solid Tumors and progression-free survival (PFS). RESULTS Grade 1/2 adverse events included fever (n = 17), emesis (n = 7), frostbite (n = 5), and local pain (n = 4). The median follow-up period and PFS were 18.5 months (range, 12-42 mo) and 13.4 months ± 6.2, respectively. At the end of follow-up, 13 patients had died and 26 were living. The mean severe local pain scores on pretreatment day 1 and posttreatment days 1, 5, 10, 15, 20, and 25 were 7.49, 7.40, 6.51, 5.81, 5.35, 5.04, and 5.44, respectively, and significant differences versus pretreatment (P < .001) were reported for posttreatment days 5-25. Immediate relief occurred more frequently in the small-tumor group (4 of 7; 57.1%; P = .018), whereas delayed relief occurred more frequently in the large-tumor group (17 of 22; 77.3%; P = .030). CONCLUSIONS Minimally invasive percutaneous cryoablation improves local pain and is a feasible treatment for recurrent RPSs.

Abstract
Management of retroperitoneal sarcomas presents technical and oncological challenges. Imaging is crucial for diagnosis and to define local tumor extent. Complete gross resection at initial presentation is the best chance for cure, but there is controversy as to how this can be best achieved. There is a long-term risk of local recurrence, which is best treated with repeat resection if feasible. The roles of radiation and chemotherapy remain undefined.

Abstract
Radical surgical resection currently represents the most effective therapy for patients with retroperitoneal sarcoma. Unfortunately, margin-negative resection often mandates extirpation of multiple retroperitoneal viscera, and such operations are nonetheless fraught with high rates of locoregional recurrence. In an attempt to improve local control and ultimately survival, adjuvant strategies of radiation and chemotherapy have been increasingly employed, with promising results. To date, however, the rarity of the disease has limited large, prospective studies investigating the efficacy of these adjuvant modalities. In this article, we review the current literature pertaining to the diagnosis, staging and treatment of retroperitoneal sarcoma and demonstrate the critical need for future large, multi-institutional studies to advance our knowledge of this uncommon disease.

Abstract
BACKGROUND Currently no prospective randomized trial has measured the efficacy of radiation therapy for resected retroperitoneal sarcomas (RPS). Our objective was to determine the effect of radiation therapy on disease-specific and overall survival between propensity score-matched surgically resected RPS patients using the Surveillance, Epidemiology, and End Results (SEER) database. PATIENTS AND METHODS The study population consisted of patients with histologically confirmed RPS who underwent surgical resection between 1988 and 2006. Exclusion criteria included multiple malignancies, distant metastasis, and unknown grade or stage. Cox modeling was used to determine covariate associations with disease-specific survival. Propensity score methods were used to perform survival analysis in patients who received radiation matched with patients who underwent surgery alone. RESULTS Prior to matching, there were 762 patients (558 surgery only, 204 surgery with radiation). Factors independently associated with radiation therapy were age (P = 0.037), geographic region (P = 0.041), grade (P = 0.047), stage (P = 0.003), and surgery type (P = 0.01). Cox modeling demonstrated that age, sex, grade, and stage were independently associated with survival. Propensity scoring (309 matched pairs) and survival analysis using Kaplan-Meier methods demonstrated no difference between propensity score-matched patients receiving radiation therapy and those who did not (P = 0.35). CONCLUSION At present, SEER patients with surgically resected RPS who received radiation therapy did not demonstrate survival benefit.

Abstract
BACKGROUND Predictors of outcome have not been established for pediatric visceral and body wall nonrhabdomyosarcoma soft tissue sarcomas (NRSTS). METHODS The study used a retrospective review of clinical features and outcome of 61 patients with visceral and body wall NRSTS evaluated at our institution between March 1962 and December 1999. RESULTS Median age at diagnosis was 9.9 years (range, birth to 17.4 years). Tumors were greater than 5 cm in 43 (70%), high grade in 33 (54%), invasive in 25 (41%), and metastatic at presentation in 14 (23%) patients. Visceral tumors (n = 27) were more likely than body wall tumors (n = 34) to be greater than 5 cm (93% vs 53%; P < .001) and invasive (70% vs 18%; P < .001) and were less likely to be resected at diagnosis (44% vs 85%; P = .001). Estimated 10-year event-free survival (EFS) and overall survival (OS) for the entire cohort were 45.5% +/- 6.9% and 56.8% +/- 6.7%, respectively. The 10-year EFS and OS were better for patients with body wall sites than for those with visceral sites (61.8% +/- 8.5% and 67.5% +/- 8.2% vs 24.2% +/- 9.4% and 43.0% +/- 10.3%; P = .004 and P = .004). The 10-year estimated cumulative incidence (CI) of local recurrence was higher for patients with visceral sites than for those with body wall sites (64.3% +/- 9.8% vs 26.5% +/- 7.7%; P = .004), whereas CI of distant recurrence was similar for the 2 sites (15.2% +/- 7.2% vs 23.5% +/- 7.4%; P = .39). CONCLUSIONS Pediatric patients with visceral NRSTS are more likely to have invasive, large, and unresectable tumors compared to those with body wall tumors. More than two thirds of visceral NRSTS recur locally, and fewer than half of patients with visceral tumors survive.

Abstract
INTRODUCTION Ovary is located inside peritoneal cavity. However, a huge malignant ovarian tumor may get involved with retroperitoneal structures. CASE REPORT We reported a case of a 70-year-old woman presented with a 2-month history of increased abdominal distention and was subsequently found to have a giant abdominal mass. A huge low signal intensity mass with the involvement of retroperitoneal structures was showed on MRI. At operation, we found that the tumor pushed mesentery and small bowel upwards with the encasement of 10 cm jejunum and was fixed posteriorly to vena cava, aorta, right iliac vessels, and right ureter. It was dissected from the retroperitoneal structures and resected en bloc with the involved jejunum. CONCLUSION Although ovary is located inside peritoneal cavity, a huge malignant ovarian tumor may get involved with retroperitoneal structures. So, great care should be taken not to injury the retroperitoneal structures as vena cava, mesenteric vessels, iliac vessels, and ureters.

Abstract
ObjectPelvic plexus tumors are unusual entities. These lesions often reach significant size prior to clinical presentation due to vague lower extremity or other symptoms refractory to exhaustive workup and the potential space of the retroperitoneum.MethodsThe authors retrospectively reviewed the charts of 44 patients who presented to Louisiana State University Health Sciences Center with pelvic plexus tumors. All such patients were included in the present study if there was at least 12 months of follow-up. Clinical evaluations were examined, including typical clinical presentation, imaging studies, and other preoperative evaluations. These tumors include 38 peripheral neural sheath tumors (86%), two malignant neural sheath tumors (5%), and four nonneural sheath tumors (9%). The authors also examined the relation of pelvic neural sheath tumors to neurofibromatosis Type 1 (NF1).ResultsHistopathological examination confirmed 18 solitary neurofibromas (41%), 12 NF1-associated neurofibromas (27%), eight schwannomas (18%), two malignant nerve sheath tumors (5%), and four other nonneural sheath tumors (9%). The other nonneural sheath tumors consisted of one each of desmoid, ganglioma, lipoma, and an unspecified calcified mass.ConclusionsThe optimal treatment for retroperitoneal lesions remains operative excision with adjunctive therapy specific to the lesion encountered.

Abstract
AIM: To analyze the surgical management of adult primary retroperitoneal tumors (APRT) and the factors influencing the outcome after operation.
METHODS: Data of 143 cases of APRT from 1990 to 2003 in the First Affiliated Hospital of China Medical University were evaluated retrospectively.
RESULTS: A total of 143 cases of APRT were treated surgically. Among them, 122 (85.3%) underwent complete resection, 16 (11.2%) incomplete resection, and 3 (3%) surgical biopsies. Twenty-nine (20.2%) underwent tumor resection plus multiple organ resections. Ninety-five malignant cases were followed up for 1 mo to 5 years. The 1-year, 3-year, and 5-year survival rates of the patients subject to complete resection was 94.9%, 76.6% and 34.3% and that of patients with incomplete resection was 80.4%, 6.7%, and 0%, respectively (P < 0.001). The Cox multi-various regression analysis showed the completeness of tumor, sex and histological type were associated closely with local recurrence.
CONCLUSION: Sufficient preoperative preparation and complete tumor resection play important roles in reducing recurrence and improving survival.
