Oncological Outcomes in Patients with Appendicular Myxofibrosarcomas: A Retrospective Study. JOURNAL OF ONCOLOGY 2021; 2021:1844816. [PMID: 34876901 PMCID: PMC8645367 DOI: 10.1155/2021/1844816] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/04/2021] [Revised: 10/28/2021] [Accepted: 11/09/2021] [Indexed: 12/05/2022]
Abstract
BACKGROUND Myxofibrosarcoma (MFS) is notorious for its infiltrative growth pattern, making wide excisions difficult to achieve. Our objective was to assess the impact of surgical margins and other factors that affected rates of local recurrence (LR), distant metastasis (DM), and overall survival (OS) of individuals undergoing resection for MFS. METHODS We retrospectively reviewed the medical records of 209 patients with appendicular soft tissue sarcomas between January 2012 and June 2018. Of these, 29 patients (14%) were diagnosed with myxofibrosarcoma. These patients underwent a total of 33 resections. The pathological analyses were conducted by an experienced musculoskeletal (MSK) pathologist. Demographics data, operative details, adjuvant therapy, and oncological outcomes were assessed. RESULTS Of the 29 patients (33 resections), the overall LR rate was 24% (7/29) and the 2-year LR rate was 17% (5/29). Factors associated with negative oncological outcomes were as follows: tumor size ≤10 cm (2-year local recurrence-free rates (LRFRs), 65%; 95% CI, 44-86%; p=0.02) and positive surgical margins grouped with surgical margins ≤0.1 cm (hazard ratio (HR), 11.74; 95% CI, 1.41-97.74; p=0.02). Chemotherapy and radiotherapy together increased the 2-year LRFR (LRFR, 100%; 95% CI, 100%, p=0.001). Two-year DM and OS rates were 15% and 79%, respectively. Female gender was a predictor of distant metastasis. Local recurrence had a negative impact on overall survival. Intraoperative analysis of resection margin accuracy was 75% (12/16) when non-MSK pathologists were involved but 100% accurate (12/12) when analyzed by an MSK pathologist. CONCLUSION Myxofibrosarcomas showed high LR rates after treatment. Close margins (≤0.1 cm) should be considered as a risk factor for LR, and LR is associated with negative overall survival. Neoadjuvant therapy in terms of combined chemotherapy and radiation therapy associates with decreased LR rates. If intraoperative assessment of margins is to be done, it should be performed by an experienced MSK pathologist.

Abstract
BACKGROUND The impact of surgical margin status on the survival of patients with extremity soft tissue sarcoma (STS) remains to be clearly defined. The evidence regarding the impact of surgical margins on survival is limited by retrospective single-institution cohort studies. We conducted a systematic review and meta-analysis to examine the impact of surgical margin status on patient survival in extremity STS. METHODS A literature search in the PubMed, EMBASE, and Cochrane Controlled Trials Register electronic databases, and a manual search of reference lists of original studies was performed. The following text words and/or Medical Subject Heading terms were searched: (neoplasm) or/and (sarcoma) and/or (connective tissue) and/or (soft tissue) and/or (extremity) and/or (extremity) and/or (surgical margin). RESULTS Six selected studies that reported a total of 2917 cases of extremity STS were published between 1994 and 2013. All the eligible studies were observational cohort studies, and the sample size ranged from 95 to 1261 patients. A meta-analysis of 6 studies showed that a positive surgical margin predicted poor 5-year OS in a random-effects model (summary hazard ratio, 1.56; 95% confidence interval, 1.12-2.17). Moderate heterogeneity was observed among the studies (P < .075; heterogeneity, 45.6%). CONCLUSIONS This meta-analysis supports the hypothesis that adequate surgical margins are associated with improved survival in extremity STS.

Abstract
Soft-tissue sarcomas pose diagnostic and therapeutic challenges to physicians, owing to the large number of subtypes, aggressive tumor biology, lack of consensus on management, and controversy surrounding interval and duration of surveillance scans. Advances in multidisciplinary management have improved the care of sarcoma patients, but controversy remains regarding strategies for surveillance following definitive local control. This review provides an updated, comprehensive overview of the current understanding of the risk of local recurrence of soft-tissue sarcoma, by examining the literature based on features such as histological type and grade, tumor size, and resection margin status, with the aim of helping clinicians, surgeons, and radiologists to develop a tailored approach to local imaging surveillance.

What Is the Success of Repeat Surgical Treatment of a Local Recurrence After Initial Wide Resection of Soft Tissue Sarcomas? Clin Orthop Relat Res 2018; 476:1791-1800. [PMID: 30794216 PMCID: PMC6259807 DOI: 10.1007/s11999.0000000000000158] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 01/31/2023]
Abstract
BACKGROUND Treatment for patients with locally recurrent soft tissue sarcomas after wide resection is challenging, and few studies have examined the results of treating these patients. In treatment of recurrent tumors, it has been reported that positive margins are correlated to local rerecurrence, but the relationship between surgical margin and survival remains controversial and risk factors for local recurrences after wide resection of soft tissue sarcomas are not well established. This study examined clinical outcomes and factors associated with survival and local rerecurrence in patients with local recurrence after initial surgical treatment who underwent another resection with a goal of negative margins. QUESTIONS/PURPOSES The purpose of this study was to determine (1) oncologic outcomes (survival rates and local rerecurrence-free rates) of surgical treatment for patients with local recurrence after wide resection; (2) whether factors associated with survival and local rerecurrence-free rates can be determined; and (3) the proportion of patients treated by amputation at final followup. METHODS Between 1992 and 2013, we treated 530 patients with soft tissue sarcoma without metastasis. Of those, 26 (5%) were lost before 3 years of followup but were not known to have died. Of the remainder, 59 have had a local recurrence. Of those with a local recurrence, 34 (58%) were treated with wide resection, whereas 25 (42%) were treated with nonsurgical treatment including chemotherapy and radiotherapy. During that period, our general indications for wide resection were patients (1) without distant metastasis; or (2) without distant lymph node metastasis, and contraindications were distant organ metastasis and/or distant lymph node metastasis. Of those treated with wide resection, 30 (88%) were available for followup. We conducted a retrospective analysis of these 30 patients with local recurrence (17 men, 13 women) who had previously undergone wide resection. Patient followup ranged from 1 to 12 years (median, 5 years). Survivorship (including overall survival and survival free from repeat recurrence) was ascertained by the Kaplan-Meier method. Factors associated with survival were evaluated by the log-rank test. Amputations were performed when limb-sparing surgery was deemed unsuitable because of extensive involvement of the limb by tumor, including invasion of multiple muscle compartments and neurovascular components. Survivorship free from amputation was ascertained by the Kaplan-Meier method. RESULTS Overall 5- and 10-year Kaplan-Meier survival rates after resection were 70% (95% confidence interval [CI], 50%-91%) and 44% (95% CI, 12%-76%), respectively, and 12 patients (40%) developed distant metastases after the second operation. Ten patients (33%) had additional local recurrences, and overall 5- and 10-year local rerecurrence-free rates were 66% (95% CI, 48%-85%) and 50% (95% CI, 18%-81%), respectively. A positive margin was associated with further recurrence (5-year local rerecurrence-free rates of positive margin: 20% [95% CI, 0%-52%], negative margin: 89% [95% CI, 74%-100%], p < 0.01) and with survival (5-year survival rates of positive margin: 36% [95% CI, 0%-75%], negative margin: 91% [95% CI, 74%-100%], p < 0.01). The survival rate was lower in patients with recurrence developing after 2 years (5-year survival rates of within 2 years: 46% [95% CI, 2%-90%], after 2 years: 83% [95% CI, 62%-100%], p = 0.01). The overall 5- and 10-year amputation-free rates were 86% (95% CI, 74%-99%) and 81% (95% CI, 67%-96%), respectively. CONCLUSIONS A surgical procedure with negative margins appears to be important for reducing the likelihood of local recurrences and improving survival of patients with rerecurrence after wide resection of soft tissue sarcomas. Although these findings need to be confirmed in larger studies, it appears that when tumor recurrence is evident within 2 years from the primary surgery, it is associated with a poor prognosis. Local recurrence within 2 years after wide resection may also be an indicator of aggressive tumor biology. LEVEL OF EVIDENCE Level IV, therapeutic study.

Abstract
Patients with retroperitoneal sarcoma can present to a variety of clinicians with non‐specific symptoms and retroperitoneal sarcomas can be incidental findings. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in non‐specialist centers. Therefore it is critical that the possibility of retroperitoneal sarcoma should be considered with prompt referral to a soft tissue sarcoma unit. This review guides clinicians through a diagnostic pathway, introduces concepts in response assessment and new imaging developments.

Abstract
PURPOSE Radiotherapy before or after resection is one of the pillars of treatment for localised high risk soft tissue sarcomas. Treatment intensification has been described with concurrent chemotherapy and hyperthermia. The aim of this study is to assess local control after multimodal treatment, focussing on the treatment of local recurrences after surgery only. PATIENTS AND METHODS Of 42 patients treated in a prospective protocol with radiotherapy and hyperthermia, nine were treated for isolated local recurrences without metastatic spread. Most patients were treated with trimodal therapy including chemotherapy with ifosfamide and underwent resection whenever possible. Median follow-up was 1.4 years. RESULTS The treatment was well tolerated. Estimated disease free survival, distant metastases free survival and local control for the whole cohort after 1.5 years were 66, 73 and 88%, respectively. Neoadjuvant vs. adjuvant treatment influenced local control with a trend to statistical significance. Resection status did not influence local control. The cohort of patients treated for local recurrence after surgery alone had a significantly impaired local control compared to multimodal treatment at primary diagnosis (100 vs. 52%, p < 0.001). CONCLUSIONS With multimodal therapy including radiotherapy and hyperthermia local tumour control is achievable even in locally recurrent tumours. The clear-cut difference of the treatment of local recurrence in contrast to primary diagnosis might either reflect difficulties in diagnosis and treatment of local recurrences or biological aggressiveness of recurrent tumours. However, we recommend to consider multimodal treatment at primary diagnosis of high risk soft tissue sarcomas.

Abstract
Although retroperitoneal sarcomas are rare tumours, they can be encountered by a wide variety of clinicians as they can be incidental findings on imaging or present with non specific symptoms and signs. Surgical resection can offer hope of cure and patient outcomes are improved when patients are managed in high-volume specialist centers. Failure to recognize retroperitoneal sarcomas on imaging can lead to inappropriate management in inexperienced centers. Therefore it is critical that a diagnosis of retroperitoneal sarcoma should be considered in the differential diagnosis of a retroperitoneal mass with prompt referral to a soft tissue sarcoma unit. In particular, the most common retroperitoneal sarcoma subtypes, liposarcoma and leiomyosarcoma, have characteristic imaging appearances which are discussed. This review therefore aims to set the context and guide clinicians through a diagnostic pathway for retroperitoneal masses in adults which arise extrinsic to the solid abdominal viscera.

Abstract
BACKGROUND Small (≤ 5 cm) soft tissue sarcomas (STS) of the extremities and the trunk wall generally have a favorable prognosis. However, 1 of 10 patients do develop metastases, and we therefore aimed to determine predictors of metastasis in a population-based cohort of patients with small STSs. PATIENTS AND METHODS In the southern Sweden health care region, 848 adult patients with STS of the extremities or the trunk wall were diagnosed between 1986 and 2010. Of these, 243 STS (29 %) were ≤5 cm. Prognostic evaluation was performed in 229 patients with localized disease at diagnosis, 181 of whom had histologic high-grade tumors. RESULTS None of the 48 patients with low-grade tumors developed metastases, whereas 24 of 181 patients with high-grade tumors (13 %) tumors did. Presence of either tumor necrosis or vascular invasion predicted development of metastases with a hazard ratio of 2.9 (95 % CI, 1.0-7.9), and tumors with both factors had a hazard ratio of 12 (95 % CI, 4.1-37) for metastasis (adjusted for size). CONCLUSIONS Our population-based series of STSs ≤5 cm demonstrate an overall good prognosis with metastases developing in 13 % of the patients with high-grade tumors. Tumor necrosis and vascular invasion were the major predictors of metastatic disease in this subset. Tumors with both these risk factors metastasized in 8 of 18 patients, which corresponds to a 12-fold increased risk of metastasis. These findings suggest that although small STS generally are linked to a good prognosis, necrosis and vascular invasion are features indicating biologically aggressive tumors for which treatment and surveillance should equal that for larger tumors.

Abstract
BACKGROUND Patients with local recurrence of soft tissue sarcomas are predisposed to future recurrences because treatment is challenging and complicated by prior therapy. This study investigated clinical outcomes following surgical procedures for locally recurrent soft tissue sarcomas and risk factors for re-recurrence and metastasis. METHODS A retrospective analysis was conducted with 105 patients (52 males, 53 females) who underwent surgical procedures for local recurrence without distant metastasis of soft tissue sarcoma between 1987 and 2009. Patient follow-up ranged from 1 to 12 years (mean 4.9 years). RESULTS Overall 5- and 10-year survival rates were 83.4 and 67.7%, respectively. Twenty-one patients (20.0%) had additional local recurrences, and 23 (21.9%) had distant metastases. Amputation rate was 10.5% at the time of surgical procedures and 17.1% at final follow-up. Locations deep within muscles in the upper limb or trunk and surgical margins <1 cm wide were risk factors for further local recurrence. Locations deep within muscles, tumor sizes >10 cm, high-grade malignancy, and local recurrence after radical surgery were risk factors for distant metastasis. CONCLUSIONS Surgical margin and location were independent prognostic factors for local control, and a wider margin was especially important for recurrent tumors located in the trunk and upper extremity. For high-grade sarcomas with local recurrence after radical surgery, new approaches are needed to prevent distant metastases.

Abstract
BACKGROUND The impact of local recurrence and surgical resection margin status on survival in extremity soft-tissue sarcomas remains to be clearly defined. Our aim was to conduct a retrospective analysis of prospectively collected data to determine the prognostic relevance of positive resection margins and local recurrence for extremity soft-tissue sarcomas for survival. METHODS Three hundred and sixty-three patients who underwent resection of localized primary extremity soft-tissue sarcomas with curative intent were selected from the United States Department of Defense Automated Central Tumor Registry. Outcomes for local recurrence, distant recurrence, disease-specific survival, and overall survival were analyzed according to clinical, pathological, and treatment variables with use of the Kaplan-Meier method (log-rank test) and the multivariate Cox regression model. RESULTS Positive margins (hazard ratio, 1.99 [95% confidence interval, 1.15 to 3.45]), local recurrence (hazard ratio, 2.93 [95% confidence interval, 1.38 to 6.23]), and distant recurrence (hazard ratio, 12.13 [95% confidence interval, 5.97 to 24.65]) were significantly associated with overall survival on multivariate Cox regression analysis. However, for disease-specific survival, local recurrence was not significant and tumor size of >10 cm (hazard ratio, 2.83 [95% confidence interval, 1.15 to 6.95]), positive margins (hazard ratio, 1.95 [95% confidence interval, 1.05 to 3.63]), and distant recurrence (hazard ratio, 9.46 [95% confidence interval, 4.37 to 20.47]) were independent adverse prognostic factors. The disease-specific survival rate for patients with localized soft-tissue sarcomas was 89% (95% confidence interval, 85% to 92%) for five years and 75% (95% confidence interval, 70% to 81%) for ten years. CONCLUSIONS Positive surgical margins are consistently associated with adverse survival-related outcomes in localized soft-tissue sarcomas of the extremity. Local recurrence had a significant impact on overall survival, but not on disease-specific survival.

Abstract
BACKGROUND Limb salvage surgery (LSS) has gained widespread acceptance as the current treatment for treating extremity soft tissue sarcoma (STS) and has been greatly refined since its inception. Combined with improved adjuvant treatment modalities, rates of local relapse have greatly decreased. Nonetheless, local recurrence still occurs and identifying the cause and the subsequent effects of local recurrence can provide valuable insights as LSS continues to evolve. METHODS This retrospective study evaluated 278 patients treated for STS of the extremities between 2000 and 2006. Of these, 41 patients developed a local recurrence while 247 did not. Tumor characteristics and prognostic outcomes were analyzed. Wilcoxon rank sum test and either χ(2) or Fisher's exact was used to compare variables. Kaplan Meier and Gray's test for cumulative risk were also performed. RESULTS Patients who had a positive margin were 3.76 times more likely to develop local recurrence when compared to those with negative margins. This corresponds to a 38% risk of local recurrence if the margins were positive after six years vs. 12% if the margins were negative. In patients who underwent a re-excision, the presence or absence of residual disease upon re-excision did not have any bearing on local recurrence (p = 0.27). In comparing patients with and without local recurrence, there was no statistically significant difference in the rate and the proportion encountering distant metastasis and death due to sarcoma (p > 0.05). CONCLUSIONS Despite advancements in surgery, radiation and imaging, positive margins still occur, and the presence of positive margins following definitive treatment continues to remain as a strong predictor for local recurrence. While local recurrence represents a negative outcome for a patient, its impact on future prognosis is influenced by a variety of factors such as time to local recurrence as well as the tumor's inherent biological characteristics.

Abstract
BACKGROUND AND PURPOSE There have been few long-term studies on the outcome of chondrosarcoma and the findings regarding prognostic factors are controversial. We examined a homogeneous group of patients with primary central chondrosarcoma of bone who were treated according to a uniform surgical protocol at our institution, in order to determine the factors that influence survival and identify potential improvements to our therapeutic algorithm. PATIENTS AND METHODS We performed a retrospective analysis of 115 patients with primary central chondrosarcoma of bone who presented with localized disease and who had a minimum follow-up of 5 years after diagnosis. 68 tumors were localized in the extremities and 47 in the axial skeleton or pelvis. 59 patients had a high-grade (II and III) and 56 a low-grade (I) tumor. 94 patients underwent surgical resection with adequate (wide or radical) margins, while 21 patients had inadequate (marginal or intralesional) margins. RESULTS Tumor grade and localization were found to be statistically significant independent predictors of disease-related deaths in multivariate analysis. The quality of surgical margins did not influence survival. The AJCC staging system was able to predict prognosis in patients with chondrosarcoma of the extremities, but not in those with tumors of the axial skeleton and pelvis. Long-term survival after secondary metastatic disease was only observed when metastases were resected with wide margins. Patients with metastases who received further treatment with conventional chemotherapy, radiotherapy, and/or further surgery had significantly better survival compared to those who received best supportive care. INTERPRETATION The outcome in patients with primary central chondrosarcoma of bone who present with localized disease is mostly affected by tumor-related parameters.

Abstract
INTRODUCTION The retroperitoneum can host a wide spectrum of pathologies, including a variety of rare benign tumours and malignant neoplasms that can be either primary or metastatic lesions. Retroperitoneal tumours can cause a diagnostic dilemma and present several therapeutic challenges because of their rarity, relative late presentation and anatomical location, often in close relationship with several vital structures in the retroperitoneal space. MATERIALS AND METHODS A comprehensive literature search was conducted using PubMed. Relevant international articles published in the last ten years were assessed. The keywords for search purposes included: retroperitoneum, benign, sarcoma, neoplasm, diagnosis and surgery, radiotherapy, chemotherapy. The search was limited to articles published in English. All articles were read in full by the authors and selected for inclusion based on relevance to this article. RESULTS Tumours usually present late and cause symptoms or become palpable once they have reached a significant size. Retroperitoneal tumours are best evaluated with good quality cross-sectional imaging and preoperative histology by core needle biopsy is required when imaging is non-diagnostic. Sarcomas comprise a third of retroperitoneal tumours. Other retroperitoneal neoplasms include lymphomas and epithelial tumours or might represent metastatic disease from known or unknown primary sites. The most common benign pathologies encountered in the retroperitoneum include benign neurogenic tumours, paragangliomas, fibromatosis, renal angiomyolipomas and benign retroperitoneal lipomas. CONCLUSIONS Complete surgical resection is the only potential curative treatment modality for retroperitoneal sarcomas and is best performed in high-volume centres by a multidisciplinary sarcoma team. The ability completely to resect a retroperitoneal sarcoma and tumour grade remain the most important predictors of local recurrence and disease-specific survival.

Abstract
BACKGROUND Multimodality treatment of primary soft tissue sarcoma by expert teams reportedly affords a low incidence of local recurrence. Despite advances, treatment of local recurrence remains difficult and is not standardized. QUESTIONS/PURPOSES We (1) determined the incidence of local recurrence from soft tissue sarcoma; (2) compared characteristics of the recurrent tumors with those of the primary ones; (3) evaluated local recurrences, metastases and death according to treatments; and (4) explored the relationship between the diagnosis of local recurrence and the occurrence of metastases. METHODS From our prospective database, we identified 618 soft tissue sarcomas. Thirty-seven of the 618 patients (6%) had local recurrence. Leiomyosarcoma was the most frequent diagnosis (eight of 37). The mean delay from original surgery was 22 months (range, 2-75 months). Mean size was 4.8 cm (range, 0.4-28.0 cm). Median followup after local recurrence was 16 months (range, 0-98 months). RESULTS Recurrent tumors had a tendency toward becoming deeper seated and higher graded. Nineteen of the 37 patients with recurrence underwent limb salvage (nine free flaps) and six had an amputation. Twenty-two (59%) had metastases, including 10 occurring after the local recurrence event at an average delay of 21 months (range, 1-34 months). Six patients developed additional local recurrences, with no apparent difference in risk between amputation (two of six) and limb salvage (four of 19). CONCLUSIONS Patients with a local recurrence of a soft tissue sarcoma have a poor prognosis. Limb salvage and additional radiotherapy remain possible but with substantial complications. Amputation did not prevent additional local recurrence or death.

Abstract
BACKGROUND Established prognostic factors influencing survival in soft tissue sarcomas include tumor stage, histopathologic grade, size, depth, and anatomic site. The presence of tumor near or at the margin of resection increases the risk of local recurrence but whether a positive surgical margin or local recurrence affect overall survival is controversial. QUESTIONS/PURPOSES We explored the impact of microscopic margin on local recurrence, metastasis, and overall survival in patients with intermediate- to high-grade soft tissue sarcomas of the extremities. We then determined whether local recurrence decreases overall survival. METHODS We retrospectively reviewed the medical records of 248 patients who had soft tissue sarcomas of the extremities treated surgically from 1995 to 2008. We estimated survival, local recurrence, and distant metastasis and examined factors potentially influencing these outcomes. The minimum followup was 0.4 years (median, 4.4 years; range, 0.4-13 years). RESULTS The 5-year cumulative incidence of local recurrence was 4.1%. Patients who presented with positive margins or a margin of 2 mm or less had a worse survival than patients who had margins of greater than 2 mm and wide margins (5-year survival, 47% versus 70% and 72%). In addition to surgical margin, developing metastasis, tumor response of less than 90% necrosis, high histopathologic grade, high AJCC stage (Stage III), increasing age, and male gender were associated with decreased overall survival. Local recurrence independently predicted decreased overall survival. CONCLUSIONS Microscopic surgical margin and local recurrence after surgical treatment should be included as risk factors predicting decreased overall survival for intermediate- to high-grade soft tissue sarcomas of the extremities.

Abstract
INTRODUCTION Retroperitoneal soft tissue sarcomas represent a relatively rare and complex therapeutic problem where surgery forms the mainstay of treatment and is technically demanding. In this study, we review a single UK centre's experience with the surgical management of retro-peritoneal soft tissue sarcoma. PATIENTS AND METHODS We present analysis of data on patients treated between 1997 and 2006, our first 75 patients. Data collected from the Access database, included patient demographics, staging modalities, peri-operative details, treatment, outcome, pathological diagnosis and subsequent complications. RESULTS A total of 75 patients (M:F, 44:31) underwent 115 resectional procedures as part of the management of retroperitoneal soft-tissue sarcoma. There were 12 major complications for the 115 procedures (morbidity of 8.69%). The 30-day operative mortality was zero and the 90-day mortality rate was 1.33% (1/75). Follow-up ranged from 16-131 months. The median disease-free survival was 69 months (range, 59-78 months). Recurrences developed in 46 patients; median time to overall recurrence was 13 months (range, 3-71 months). Of these 46, 22 developed localised recurrence, which was amenable to further resection. In the cohort of patients with recurrent disease, median survival in those who underwent surgery was 53 months (range, 30-76 months) and median survival in those who did not undergo surgery was 30 months (range, 18-41 months) and this difference was statistically significant (log rank, P = 0.01). CONCLUSIONS Extensive resectional surgery with minimal morbidity, devoid of mortality is feasible in the treatment of retroperitoneal sarcoma. Development of recurrent disease is a significant factor influencing survival; however, localised recurrences are amenable to surgery and this can lead to improved survival.

Abstract
BACKGROUND Local recurrence after surgical resection is the main cause of disease-related mortality in patients with primary retroperitoneal sarcoma (RPS). This study analysed predictors of local recurrence and disease-specific survival. METHODS A prospective database was reviewed to identify patients who underwent surgery for primary RPS between 1990 and 2009. Patient demographics, operative outcomes and tumour variables were correlated with local recurrence and disease-specific survival. Multivariable analysis was performed to evaluate predictors for local recurrence and disease-free survival. RESULTS Macroscopic clearance was achieved in 170 of 200 patients. The median weight of tumours was 4.0 kg and median maximum diameter 27 cm. Resection of adjacent organs was required in 126 patients. The postoperative mortality rate was 3.0 per cent. Seventy-five patients developed local recurrence during follow-up. At 5 years the local recurrence-free survival rate was 54.6 per cent and the disease-specific survival rate 68.6 per cent. Inability to obtain macroscopic clearance at resection and high-grade tumours were significant predictors for local recurrence and disease-specific survival. CONCLUSION Complete macroscopic excision should be the goal of surgical resection. Ability to resect a RPS completely and tumour grade are the most important predictors of local recurrence and overall survival.
