Abstract
OBJECTIVES To explore the predictive value of inflammatory-nutritional score (INS) and a nomogram for survivals in head and neck soft tissue sarcoma (HNSTS) patients with negative resection margins (R0). METHODS Clinical characteristics and hematological features of 315 HNSTS patients underwent R0 surgery were analyzed. RESULTS The 5-year overall survival (OS) rate, 3-year recurrence-free survival rate and disease-free survival (DFS) rate were 77.3%, 61.0% and 55.4%, respectively. High INS was associated with a deep tumor location (p < 0.001), high tumor grade (p < 0.001), and advanced AJCC stage (p < 0.001). The low-risk group (INS 0) exhibited a higher 5-year OS rate and 3-year DFS rate than others (87.6% vs. 81.3% vs. 53.3%, p < 0.001; 62.2% vs. 56.9% vs. 37.9%, p = 0.007). The INS (p = 0.023), tumor depth (p < 0.001), pT classification (p = 0.022), pN classification (p < 0.001) and tumor grade (p < 0.001) were independent survival predictors. Moreover, a novel nomogram for predicting OS was generated and assessed by the concordance index, exhibiting a better performance than the p7TNMG classification alone (p < 0.001). CONCLUSIONS For R0 resected HNSTS patients, the oncological outcomes can be predicted using the INS system and a specific nomogram.

Abstract
Cancer diagnoses have been increasing worldwide, and solid tumors are among the leading contributors to patient mortality, creating an enormous burden on the global healthcare system. Cancer is responsible for around 10.3 million deaths worldwide. Solid tumors are one of the most prevalent cancers observed in recent times. On the other hand, early diagnosis is a significant challenge that could save a person's life. Treatment with existing methods has pitfalls that limit the successful elimination of the disorder. Though nanoparticle-based imaging and therapeutics have shown a significant impact in healthcare, current methodologies for solid tumor treatment are insufficient. There are multiple complications associated with the diagnosis and management of solid tumors as well. Recently, surface-conjugated nanoparticles such as lipid nanoparticles, metallic nanoparticles, and quantum dots have shown positive results in solid tumor diagnostics and therapeutics in preclinical models. Other nanotheranostic material platforms such as plasmonic theranostics, magnetotheranostics, hybrid nanotheranostics, and graphene theranostics have also been explored. These nanoparticle theranostics ensure the appropriate targeting of tumors along with selective delivery of cargos (both imaging and therapeutic probes) without affecting the surrounding healthy tissues. Though they have multiple applications, nanoparticles still possess numerous limitations that need to be addressed in order to be fully utilized in the clinic. In this review, we outline the importance of materials and design strategies used to engineer nanoparticles in the treatment and diagnosis of solid tumors and how effectively each method overcomes the drawbacks of the current techniques. We also highlight the gaps in each material platform and how design considerations can address their limitations in future research directions.

Abstract
PURPOSE Magnetic resonance imaging (MRI) is useful in the diagnosis of local recurrence, but few studies have explored recurrence in MRI in patients after reconstructive surgery. The purpose of this study was to analyze MRI findings of locoregional recurrence following reconstructive surgery after malignant soft tissue tumor resection. METHOD Fifty-three postoperative MRIs from 37 patients who underwent reconstructive surgery after malignant soft tissue tumor resection were retrospectively reviewed. A total of 76 enhancing lesions, including 40 locoregional recurrences and 36 postoperative changes, were analyzed regarding morphology (location on the transplanted tissue, border, and shape) and the signals on T1- and T2-weighted imaging (T1WI, T2WI), fat-suppressed (FS) T2WI, and contrast-enhanced FS T1WI. Diffusion-weighted imaging with an apparent diffusion coefficient was assessed. A chi-squared test and Fisher's exact test were used for statistical analysis. RESULTS The most common site of recurrent tumors and postoperative changes was the peripheral margin on transplanted tissue (63% and 61%, respectively p = 0.907). Recurrent tumors commonly appeared with well-defined borders (75%) as well as nodular appearance (98%), hyperintensity on T2WI (85%) and FS-T2WI (95%), isointensity on T1WI (65%), impeded water diffusion (55%), and intense (50%) or moderate (45%) enhancement. Postoperative changes showed ill-defined borders (75%), nodular appearance (56%), facilitated water diffusion (69%), and moderate (86%) enhancement, which were significantly different from those of recurrent tumors (p ≤ 0.020). CONCLUSIONS Common and partitioning MRI features of locoregional recurrence were well-defined borders, nodular shape, impeded water diffusion, and intense enhancement. Peripheral margins on transplanted tissue were common sites in both recurrent tumors and postoperative changes.

Oncologic outcomes in myxofibrosarcomas: the role of a multidisciplinary approach and surgical resection margins. ANZ J Surg 2023; 93:577-584. [PMID: 36772961 DOI: 10.1111/ans.18320] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/16/2022] [Revised: 01/27/2023] [Accepted: 01/31/2023] [Indexed: 02/12/2023]
Abstract
BACKGROUNDS Myxofibrosarcomas (MFS) are malignant soft tissue sarcomas with an infiltrative growth pattern and propensity for local recurrence(LR).We aimed to assess our management of MFS and make recommendations about the role of a multidisciplinary team approach and margin widths. METHODS Fifty-seven patients were identified with MFS treated at a single sarcoma centre between 1998 and 2020. Patients were stratified based on whether they presented for a planned resection (59.6%) or after an unplanned resection (40.4%) performed at a non-specialized facility. All patients underwent radiotherapy before definitive surgery. RESULTS 73.7% underwent a combined onco-plastic approach. The 5 year LRFS rate was 78.2% (84.4%, planned, versus 70.1%, unplanned, P = 0.194) and found comparable oncological outcomes between the planned and unplanned groups for the 5 year metastasis free survival (74.5% versus 86.1%, P = 0.257), disease free survival (70.1% versus 72.4%, P = 0.677), and Overall Survival (64.5% versus 75.9%, P = 0.950). Margin width ≥ 2 cm was obtained in 84.2% of cases and improved local control (HR = 0.22; 95% CI 0.06-0.81; P = 0.023), metastasis (HR = 0.24; 95% CI 0.07-0.80; P = 0.019) and mortality rates (HR = 0.23; 95% CI 0.09, 0.61; P = 0.003) compared to <2 cm. Margin width > 3 cm did not further affect oncological outcomes. CONCLUSION Our study shows that a multidisciplinary team approach allows the achievement of low local recurrence rate and good oncological outcomes of myxofibrosarcomas, regardless of presentation status. We recommend a minimum of 2 cm margin width.

Low rate of function-limiting side effects with high-dose adjuvant radiotherapy in high-grade soft tissue extremity sarcomas: a retrospective single-center analysis over 10 years. J Cancer Res Clin Oncol 2022:10.1007/s00432-022-04423-1. [PMID: 36287264 PMCID: PMC9607852 DOI: 10.1007/s00432-022-04423-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/29/2022] [Accepted: 10/14/2022] [Indexed: 11/17/2022]
Abstract
Background Over the years, radiotherapy has been established as a tool to improve local control for high-grade sarcomas. Although the European Society for Medical Oncology guidelines has taken notice of a shift toward a neoadjuvant radiotherapy approach, the American Society for Radiation Oncology guidelines clearly favor a neoadjuvant approach, citing debilitating long-term adverse effects when radiotherapy is applied postoperatively. In this study, we examined these irradiation-associated adverse events for adjuvant radiotherapy and focused on the prognostic factors for disease outcome, including local control. Methods In this retrospective study, data for 106 patients with extremity soft-tissue sarcomas diagnosed between 1997 and 2021, of which 40 received adjuvant radiotherapy, were collected from the clinical and radiological information systems of a high-volume sarcoma treatment center. These data were then analyzed for radiation-associated side effects as well as predictive factors for overall survival, disease-free survival, local control, and surgical complications. Results Radiotherapy was beneficial to patients improving local control, especially for high-grade sarcomas, even when those were resected with negative margins. Side effects due to radiotherapy occurred in 87.5% of the patients, and these effects primarily included radiation dermatitis in 67.5%; however, only 40.0% had any adverse event of ≥ grade 2 according to Common Terminology Criteria for Adverse Events. Long-term function-limiting side effects occurred in 45.0% of the patients; 10% exhibited ≥ grade 2 function-limiting adverse events. Greater time between surgery and adjuvant radiotherapy was beneficial for the patients, whereas joint infiltrating sarcomas were associated with more severe long term, function-limiting adverse events. 28.3% of the patients experienced a recurrence at any location (median time 18.35 months) and in 16% the recurrence was local (median time 16.11 months), resulting in 1, 3, and 5 year disease-free survival rates of 74.1, 58.9, and 38.5% and local control rates of 78.7, 61.6, and 42.8% were observed, respectively. Conclusion Recurrences may be avoided with high-dose radiation, especially for high-grade G2 and G3 sarcomas, even after complete R0 resection. This resulted in a low rate of severe long-term function-limiting adverse events. Thus, adjuvant radiotherapy should be seriously considered when planning patient treatment, especially when treating patients that present with high-grade sarcomas.

Abstract
Early studies of the management of soft tissue sarcoma at Memorial Sloan Kettering Cancer Center were influenced by development of robust prospective long-term databases. Increasing capacity for molecular diagnostics has identified a myriad of subtypes with definable natural history. Accurate identification of tissue-specific risk of recurrence and disease-specific survival have increasingly allowed selective use of surgery, radiation therapy, and target-specific cytotoxic and immune therapies.

Abstract
In Soft Tissue Sarcomas (STS) referral centre many patients have already had an incomplete tumour resection. In the majority of specimen, tumoral residual is detected and linked to a worsen prognosis. Systematic surgical re-resection of the scar tissue area is often performed. Some authors suggested to postpone re-resections until a clinically evident local recurrence is detected. A searching strategy was applied to Pubmed-Central and Ovid Medline. Odds ratio (OR) for local recurrence (LR), distant metastasis (MTS) or overall survival (OS) were calculated comparing patients who had tumour residual to people who hadn't. OR of local recurrences, distant metastasis and OS were calculated in planned vs unplanned-excisions groups. OR to develop a metastasis and OS after a local recurrences were calculated. Residual tumour led to an OR for LR of 3,56, OR of MTS was 3,42; OR of decreased OS was 3,42. Having a LR lead to a OR of 1,55 for MTS and to a OR of decreased OS of 2,32. Patients who underwent a re-excision compared to planned surgery did not have an increased OR of LR and had an OR to develop a MTS of 0,56. Our data confirm that there is a strong correlation between local recurrences, distant relapses and overall survival. Although there is a selection bias; this analysis highlights the optimal oncological outcome in patients who underwent re-resection. The rationale for systematic re-resection after unplanned excision of soft tissue sarcomas is very strong and this treatment remains the gold standard of care in these patients.

Abstract
BACKGROUND Resecting non-palpable soft tissue tumors presents a unique challenge, particularly with recurrent disease in which surrounding tissue has been surgically manipulated and often irradiated. SAVI SCOUT® is a radar-based localization device that was developed for breast tumor localization and was recently FDA-approved for localization of soft tissue tumors. Application of this technology to soft tissue sarcoma has not been previously reported. METHODS We assembled a single-institution retrospective case series of patients with trunk and extremity sarcomas resected by five sarcoma surgeons using SAVI SCOUT® from December 2018 to May 2020. Reflectors were placed preoperatively using image-guidance, and the radar detector was used intraoperatively to localize the target lesion. Clinical variables were abstracted from the electronic medical record including treatment history, pathology, and early oncologic outcomes. Using a focused review, we compared margin status and recurrence rates with previously published cohorts. RESULTS Ten SAVI SCOUT®-localized sarcoma resections were performed. Eight were for locally recurrent disease, of which seven (83%) had prior radiation. The remaining lesions became non-palpable after neoadjuvant chemotherapy. SAVI SCOUT® facilitated resection in all cases with a margin-negative resection rate (77%) comparable to prior cohorts. In this high-risk population with a median follow-up of 14 months, only one patient recurred locally 7.5 months after SAVI SCOUT®-localized resection, requiring re-resection. CONCLUSION SAVI SCOUT® technology facilitated resection of non-palpable recurrent sarcoma of the trunk and extremities in all ten cases attempted. In a high-risk patient population, the pattern of recurrence has been primarily distant with one instance of local tumor recurrence.

Abstract
Soft tissue sarcomas (STS) encompass a diverse family of neoplasms of mesenchymal origin, marked by significant heterogeneity in terms of physiopathology, molecular characterisation, natural history and response to different therapies. This review aims to summarise the current strategies for the management of patients with STS, including surgery, systemic treatments and radiation therapy, along with considerations applicable to the most frequent subtypes, as well as particularities associated with less common and specific histologies. It also provides insights into upcoming strategies to tackle this challenging group of diseases.

Abstract
Cell-free DNA (cfDNA), which are small DNA fragments in blood derived from dead cells including tumor cells, could serve as useful biomarkers and provide valuable genetic information about the tumors. cfDNA is now used for the genetic analysis of several types of cancers, as a surrogate for tumor biopsy, designated as "liquid biopsy." Rhabdomyosarcoma (RMS), the most frequent soft tissue tumor in childhood, can arise in any part of the body, and radiological imaging is the only available method for estimating the tumor burden, because no useful specific biological markers are present in the blood. Because tumor volume is one of the determinants of treatment response and outcome, early detection at diagnosis as well as relapse is essential for improving the treatment outcome. A 15-year-old male patient was diagnosed with alveolar RMS of prostate origin with bone marrow invasion. The PAX3-FOXO1 fusion was identified in the tumor cells in the bone marrow. After the diagnosis, cfDNA was serially collected to detect the PAX3-FOXO1 fusion sequence as a tumor marker. cfDNA could be an appropriate source for detecting the fusion gene; assays using cfDNA have proved to be useful for the early detection of tumor progression/recurrence. Additionally, the fusion gene dosage estimated by quantitative polymerase chain reaction reflected the tumor volume during the course of the treatment. We suggest that for fusion gene-positive RMSs, and other soft tissue tumors, the fusion sequence should be used for monitoring the tumor burden in the body to determine the diagnosis and treatment options for the patients.

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
Following treatment 40% of soft tissue sarcoma (STS) patients suffer disease recurrence. In certain cancers circulating cell free DNA (cfDNA) and circulating tumour-derived DNA (ctDNA) characteristics correlate closely with disease burden, making them exciting potential sources of biomarkers. Despite this, the circulating nucleic acid characteristics of only 2 STS patients have been reported to date. To address this we used an Ion AmpliSeq™ panel custom specifically designed for STS patients to conduct a genetic characterisation of plasma cfDNA, buffy coat (germline) DNA and where available Formalin-Fixed Paraffin-Embedded (FFPE) primary STS tissue DNA in a cohort of 11 metastatic STS patients. We found that total cfDNA levels were significantly elevated in the STS patients analysed, and weakly correlated with disease burden. Using our Ion AmpliSeq™ panel we also successfully detected ctDNA in 4/11 (36%) patients analysed with a wide variety of STS subtypes and disease burdens. This evidence included the presence of cancer associated TP53 / PIK3CA mutations in 2 patients' plasma and matched primary STS tumour tissue, and in the plasma alone for 2 patients. We also identified 2 potential examples of allelic loss of heterozygosity in an additional patient's STS DNA and cfDNA. This is the largest study performed characterising STS patient cfDNA/ctDNA and confirms that the field remains an attractive potential source of novel STS biomarkers. Further work is required to investigate the circulating nucleic acid characteristics of individual STS subtypes, and the potential prognostic or therapeutic roles that cfDNA/ctDNA may hold for patients with these complex tumours.

Abstract
OBJECTIVE Due to minimal tissue violation in percutaneous core needle biopsy (CNB), in contrast to open biopsy, the risk of tumor seeding and subsequent local recurrence (LR) along the biopsy tract remains unclear in extremity soft tissue sarcoma (STS). This study sought to examine the association of CNB tract resection on LR in a large STS institutional database. MATERIALS AND METHODS After a retrospective review of the 116 patients who underwent CNB prior to surgery for previously untreated non-metastatic extremity STS, 36 patients who did not have CNB tracts resected (CNB-NR) were matched with 36 who had CNB tracts resected (CNB-R) for the factors that are known to affect LR. RESULTS Two patients (6%) developed LR in the CNB-R group, whereas three patients (8%) developed LR in the CNB-NR group (P = 0.643). On Kaplan-Meier analysis, there was no significant difference in LR-free survival between the two groups (94.3% ± 3.9 for the CNB-R group vs. 93.8% ± 4.3 for the CNB-NR group, P = 0.747). CONCLUSION Our data suggest any influence of a CNB tract resection on LR, within the limitations of this study, is likely to be of minor clinical importance in extremity STS. Although it would be prudent to resect the CNB tract in most cases, not resecting the CNB tract is a feasible option if identification or removal of the CNB tract proves difficult.

Abstract
The management of recurrent soft tissue sarcoma is a challenging problem for clinicians and has a significant physical, mental, emotional, and oncologic impact for the patient. Despite excellent limb-preservation therapies, approximately one-quarter of patients may eventually develop recurrence of disease. How to most appropriately manage these patients is a matter of debate. Several treatment options exist, including surgical resection, irradiation, systemic chemotherapy, amputation, and regional therapies. This article highlights the management of recurrent extremity soft tissue sarcoma.

Abstract
PURPOSE Flap reconstruction has become an essential component in soft tissue sarcoma treatment. However, the clinical features of local recurrence after soft tissue sarcoma resection and flap reconstruction remain unclear. The present study aimed to establish effective follow-up strategies after soft tissue sarcoma resection and flap reconstruction. METHODS Data from patients who underwent soft tissue sarcoma resection and immediate flap reconstruction were retrospectively reviewed. Follow-up after surgery included history taking and physical examination during every visit to the hospital. Magnetic resonance imaging to evaluate the primary site was performed six months after the end of treatment then annually for ten years. The methods of detection of local recurrence were assessed. RESULTS A total of 229 consecutive patients were included in the present study. During a median follow-up period of 40 months, 33 patients (14.4%) developed local recurrence. Twenty-three recurrences that occurred on the margin of the transferred flap were detected as palpable mass prior to radiological assessment; among the remaining ten recurrences that occurred in the deep layer of the transferred flap, six were detected by abnormal clinical findings and four were clinically occult and detected by surveillance radiological assessment. CONCLUSIONS Surveillance radiological assessment has an important role in early detection of local recurrence that develops in the deep layer of the transferred flap. Therefore, meticulous clinical assessment combined with routine radiological study should be performed during follow-up evaluation for local recurrence after soft tissue sarcoma resection and flap reconstruction.

Abstract
INTRODUCTION The association of symptom duration with survival remains controversial in soft-tissue sarcoma (STS). MATERIALS AND METHODS We determined whether the length from initial symptoms to specialist consultation affects prognosis in STSs. We retrospectively reviewed 152 primary STS patients (with 142 non-small round cell sarcomas) who consulted our specialist hospital. The factors that affected the length of the period from the initial symptoms to specialist consultation and the length of the delay at the clinic before specialist hospital referral were investigated. The relation between the length of the period from symptom onset and overall survival was also analyzed. RESULTS Unplanned excision and superficial tumor were significantly associated with increasing duration from the initial symptoms to specialist hospital referral. Multivariate analysis revealed that tumors over 5 cm (P=0.002 and 0.005) and symptoms within 6 months (P=0.017 and 0.016) were independent poor prognostic factors of overall survival among the pretreatment factors when analyzing all and non-small round cell STSs. CONCLUSIONS This is a first report to show the independent prognostic role of symptom duration in STSs on multivariate analysis. Considering the impact of symptom duration on survival in these heterogenous tumors, careful follow-up and consideration of treatment are necessary for patients with short symptom duration.

Abstract
BACKGROUND Literature on outcome after local recurrence (LR) in chondrosarcoma is scarce and better appreciation of prognostic factors is needed. OBJECTIVES (1) To evaluate post-LR oncologic outcomes of disease-specific survival and subsequent LR and (2) to identify prognostic factors for post-LR oncologic outcomes. PATIENTS AND METHODS Review of 28 patients with locally recurrent chondrosarcoma from the original cohort of 150 patients, who were treated surgically with or without adjuvants between 1982 and 2011, was performed. Mean age was 46 years (range, 21-73) which included 20 males and 8 females with mean follow up of 8.4 ± 7.5 years (range, 1.2-31.0). RESULTS Post-LR survival at 5 years was 58.6 ± 10.3%. Age greater than 50 years (P = 0.011) and LR occurring within 1 year of primary surgery (P = 0.011) independently predicted poor survival. Seven patients suffered subsequent LR, which was significantly affected by surgical margin for LR (P = 0.038). CONCLUSION Long-term survival of locally recurrent chondrosarcoma is achievable in a substantial number of patients. Older age at onset of LR and shorter interval from primary surgery to LR identifies high risk patients for poor post-LR survival while, wide surgical margins at LR surgery reduces the risk of subsequent LR.

Abstract
Soft tissue sarcoma is a rare disease. We began a prospective database for in-patients treated on the surgical service at Memorial Sloan-Kettering in 1982. We now celebrate 30 years of this database which has been reviewed and cataloged constantly on a weekly basis. We approach 10,000 treated patients. The study of this heterogeneous group of diverse pathology rising in the soft tissue has been fascinating. We have learned about demographics, prevalence, incidence, and have recognized the value of such databases in describing not just outcome but biology. Site is an important determinant of outcome and illustrates the complexities of including all sites in any staging system. For example, local recurrence in the extremity, while associated with a decrease in survival, is clearly not causative. Conversely, retroperitoneal sarcoma, particularly liposarcoma, is a common locally recurring disease with local progression often the cause of disease-specific mortality. Genetic predispositions have been defined. Radiation therapy and lymphedema, both alone and in combination, predispose to the development of sarcoma. These observations have important relevance as we increasingly utilize radiation therapy to minimize local recurrence in early stage breast cancer and ductal carcinoma in situ. It is clear that outcome is histology specific and wide variations in outcome, depending on the underlying histological types and subtypes, are evident. We have established very clearly that limb preservation as opposed to amputation is equally efficacious and does not diminish survival. Radiation therapy can limit local recurrence but must be balanced against side effects. Unfortunately, the majority of chemotherapeutic regimens have had minimal benefit.

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 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.

Novel dedifferentiated liposarcoma xenograft models reveal PTEN down-regulation as a malignant signature and response to PI3K pathway inhibition. THE AMERICAN JOURNAL OF PATHOLOGY 2013; 182:1400-11.

Abstract
Liposarcoma is a type of soft tissue sarcoma that exhibits poor survival and a high recurrence rate. Treatment is generally limited to surgery and radiation, which emphasizes the need for better understanding of this disease. Because very few in vivo and in vitro models can reproducibly recapitulate the human disease, we generated several xenograft models from surgically resected human dedifferentiated liposarcoma. All xenografts recapitulated morphological and gene expression characteristics of the patient tumors after continuous in vivo passages. Importantly, xenograftability was directly correlated with disease-specific survival of liposarcoma patients. Thus, the ability for the tumor of a patient to engraft may help identify those patients who will benefit from more aggressive treatment regimens. Gene expression analyses highlighted the association between xenograftability and a unique gene expression signature, including down-regulated PTEN tumor-suppressor gene expression and a progenitor-like phenotype. When treated with the PI3K/AKT/mTOR pathway inhibitor rapamycin alone or in combination with the multikinase inhibitor sorafenib, all xenografts responded with increased lipid content and a more differentiated gene expression profile. These human xenograft models may facilitate liposarcoma research and accelerate the generation of readily translatable preclinical data that could ultimately influence patient care.

Histologic parameters predictive of disease outcome in women with advanced stage ovarian carcinoma treated with neoadjuvant chemotherapy. Transl Oncol 2012; 5:469-74.

Abstract
The use of neoadjuvant chemotherapy followed by tumor reduction surgery, also called interval debulking surgery (IDS), is considered an alternative therapeutic regimen for selected patients with advanced stage epithelial ovarian cancer (EOC). Although minimal residual disease has been proven to be a prognostic factor in traditional cytoreduction for advanced stage EOC, predictive factors after IDS still remain unexplored. The aim of this study was to determine the prognostic value of post-neoadjuvant histologic changes with clinical outcome. Three pathologists evaluated 67 cases for the following parameters: fibrosis, necrosis, residual tumor, and inflammation. The Cohen's kappa statistic was used to measure agreement among pathologists. Univariate and multivariate Cox proportional hazards models were used to determine the association between histologic parameters and recurrence-free survival (RFS) and overall survival (OS). There was substantial to almost perfect agreement among the three pathologists in all four histologic parameters (k ranged from 0.65 to 0.97). Fibrosis was associated with longer RFS (P = 0.0257) with a median of 20 months for tumors with fibrosis (3+) versus 12 months for tumors with fibrosis (1+, 2+) and longer OS (P = 0.0249) with a median of 51 months for tumors with fibrosis (3+) versus 32 months for tumors with fibrosis (1+, 2+). Our results revealed that patients with tumors exhibiting fibrosis (1+, 2+), as well as necrosis (0, 1+), had significant shorter RFS and OS (P = 0.059 and P = 0.0234, respectively). We suggest that the assessment of fibrosis and necrosis should be implemented in pathologic evaluation and prospectively validated in future studies.

Abstract
BACKGROUND Malignant fibrous histiocytoma (MFH) of soft tissue is one of the most common sarcoma in adulthood. However, only a few series have separately studied the clinical behavior and prognosis of this malignancy. METHODS We retrospectively reviewed 61 patients treated for extremity soft tissue high-grade MFH. Four patients had a history of another malignancy and were excluded from analysis. In 12 referred patients with incomplete excision, re-excision of the tumor bed was offered. Clinical and treatment variables were analyzed for their impact on treatment complications, local recurrence (LR), metastatic disease (MD) and overall survival (OS). RESULTS Four patients underwent primary amputation. Twenty-three patients necessitated a primary reconstructive procedure for wound closure. Wound healing complication (WHC) developed in 28.3 % of the limb sparing group of patients. LR developed in 11 patients (19.3 %), while 6 of them had second LR. Eighteen patients (31.5 %) developed MD, involving lung at least. Patients who developed MD <12 vs >12 months, died within 19.3 vs 8 months mean time (p < 0.05). Overall survivorship was 66.7 % at 5 years. No statistically significant variables were identified for LR, while multivariate analysis for MD revealed tumor size >5 cm as the only statistically significant variable. For OS, development of MD and age >70 years emerged as independent prognostic factors. CONCLUSIONS The overall prognosis is poor. LR, although can be managed with tumor re-excision, has high second recurrence rate. Increased tumor size is associated with shorter metastasis-free interval which significantly decreases survival.

Abstract
INTRODUCTION Resection margins constitute a recognized risk factor for local recurrence, but their impact on survival is less clear. HYPOTHESIS Infiltrative proliferation and satellite nodules are prognostic factors for local and systemic aggressiveness. TYPE OF STUDY Retrospective cohort study. PATIENTS AND METHODS In 105 patients under curative treatment, resection quality was assessed on UICC criteria (R0/R1) and on a modified version (R0M/R1M) taking account of proliferation contours and satellite nodules for narrow margins (<1mm). Uni- and multi-variate analysis was performed, and Kaplan-Meier survival curves were compared on log-rank. RESULTS Mean 5-year local recurrence-free survival (LRFS) was 0.64 [0.52-0.76] after R1 surgery, 0.9 [0.85-0.95] after R0, 0.64 [0.519-0.751] after R1M and 0.92 [0.87-0.96] after R0M. Resection type according to R classification correlated with disease-free survival (DFS) (P=0.028), but not with metastasis-free survival (MFS) (P=0.156). Resection type according to RM classification correlated with DFS and MFS. Multivariate analysis disclosed correlations between LRFS rate and RM resection type (HR 6.77 [1.78-25.7], P=0.005), DFS rate and RM resection type (HR 2.83 [1.47-5.43], P=0.001) and grade (HR=3.17 [1.38-7.27], P=0.003), and MFS and grade (HR=3.96 [1.50-10.5], P=0.006). DISCUSSION The microscopic aspect of the proliferation contours and presence of satellite nodules were confirmed as prognostic factors for local and systemic aggressiveness. They impact both disease-free survival and metastasis-free survival in case of margins less than 1mm. Their systematic consideration may help identify patients with elevated systemic risk.

Abstract
BACKGROUND It is important to understand the relative importance of prognostic variables in patients with soft tissue sarcomas. The purpose of this study was to describe the hierarchical relationships between features inherent to completely excised, localized high-grade soft tissue sarcomas of the extremity and compare the associations to those previously reported. METHODS Data were collected from the Memorial Sloan-Kettering Cancer Center Sarcoma Database. All adult patients with high-grade extremity soft tissue sarcomas who underwent complete excision (R0 margins) at our institution between 1982 and 2010 were included in the analysis. Bayesian belief network (BBN) modeling software was used to develop a hierarchical network of features trained to estimate the likelihood of disease-specific survival. Important relationships depicted by the BBN model were compared to those previously reported. RESULTS The records of 1318 consecutive patients met the inclusion criteria, and all were included in the analysis. First-degree associates of disease-specific survival were the primary tumor size; presence of and time to distant recurrence; and presence of and time to local recurrence. On cross-validation, the BBN model was sufficiently robust, with an area under the curve of 0.94 (95 % confidence interval 0.93-0.96). CONCLUSIONS We successfully described the hierarchical relationships between features inherent to patients with completely excised high-grade soft tissue sarcomas of the extremity. The relationships defined by the BBN model were similar to those previously reported. Cross-validation results were encouraging, demonstrating that BBN modeling can be used to graphically illustrate the complex hierarchical relationships between prognostic features in this setting.

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 Adjuvant radiotherapy (RTE) still has a fundamental role as a post-operative treatment of locally advanced soft tissues sarcomas of the extremities. Moreover the employment of combined modalities in locally advanced soft tissues sarcomas of the extremities allow to maximize the chance of local cure even in difficult presentation cases, and possibly improve survival, especially in high-risk disease patients. In patients with sarcomas of the extremities in which definitive surgery has not been radical (with positive or "close" margins) radiotherapy can improve the results in terms of Disease Free Survival (DFS) and, together with chemotherapy, of Overall Survival (OS). We recommend radiotherapy in case of deep tumor location, inadequate surgical margins and grade 3 tumour; for positive or "marginal (or close)" excision (that means inadequate surgery) or in selected patients with a bad prognosis, we believe that a multidisciplinary approach can be preferable. INTRODUCTION Adjuvant radiotherapy (RTE) still has a fundamental role as a post-operative treatment. In patients with sarcomas of the extremities in whom definitive surgery has been or not radical (positive or "close" margins), radiotherapy with chemotherapy can improve the results in terms of Disease Free Survival (DFS) and Overall Survival (OS), while RTE alone seems to improve local control. MATERIALS AND METHODS From 1/2000 to 12/2005 we treated 34 patients affected by locally advanced sarcomas of the upper or lower extremities with radiotherapy (doses ranging from 54 to 66 Gy) and chemotherapy in 18/34 with an adjuvant scheme that consisted in Epirubicine (120 mg/m(2)) plus Ifosfamide (7000-9000 mg/m(2)). RESULTS Disease Free Survival (DFS) and the Overall Survival (OS) rates were 76% and 82%, respectively. Eighteen patients developed one or more long-term side effects. Most of these complications were mild: all patients experienced only erithema, edema, local sclerosis or moderate pain. CONCLUSION Radiotherapy has an important role as a post-operative treatment also when surgery was non-radical. It improves local control more in patients with high-grade sarcomas of the extremity with positive or close margins. It is still difficult to assess the role of adjuvant chemotherapy.

Abstract
Treatment of soft tissue sarcomas requires an individual plan which considers interdisciplinary recommendations and the various clinical situations. Anatomical region, histological grading and typing, and tumor size necessitate adjusted methods of reconstruction. The biopsy should be performed at the institution where the patient is treated. In general surgical resection of the tumor will be the treatment of choice. Adjuvant therapies are applied according to anatomical region and size and grading of the tumor. Surgery alone is recommended only in small (<5 cm), superficial, low-grade sarcomas. Sarcomas larger than 5 cm in diameter should be treated by surgery and radiotherapy, achieving excellent results, although in high-grade sarcomas more than 50% of patients still will experience metastatic disease. In case of locally recurrent disease, surgical revision with tumor-free resection margins followed by radiotherapy should be the aim. This applies even for patients who had had radiotherapy after the first excision. In this case brachytherapy is a good modality of tissue-sparing treatment.

Abstract
Soft tissue sarcomas are very rare tumors. Available data are based on only a few prospective randomized trials. Most studies are retrospective, reviewing the results of single institutions. Furthermore, universally accepted treatment protocols for adult patients are lacking. Several prognostic factors have been identified, including grading, tumor size and development of metastatic disease; however, the relevance of other important aspects in the treatment of patients with soft tissue sarcomas remains unknown or subject to controversy. The main issues concern: which surgical margin width is safe from an oncological perspective? Does local recurrence influence survival? Can systemic chemotherapy improve prognosis? Is radiotherapy necessary in every case? Should it be applied pre-, post- or intraoperatively? What is the value of assessing the response after neoadjuvant therapy? These topics are examined in this review.

Abstract
We reviewed the medical files of nine patients with localised soft-tissue sarcomas of the extremities treated with surgical resection, free vascularised tissue transfer, and computerised after-loading iridium-192 high dose rate brachytherapy over a period of 8 years. All patients had external beam radiation therapy in fractions with a total dose of 48-52 Gy, followed by surgery at approximately 4-5 weeks post-irradiation. Surgical treatment included wide resection of the primary tumour in six patients, and marginal resection in three patients. Microsurgical reconstruction of the soft-tissue defect used a free vascularised musculocutaneous flap that included the gracilis flap in five patients, the latissimus dorsi flap in four patients, and the radiovolar flap in one patient. Postoperative brachytherapy dose ranged from 12 to 24 Gy. Adjuvant chemotherapy was administered in five patients with large tumours and marginal resection. At a mean follow-up of 36 months, eight patients were still alive with no evidence of local recurrence or distant metastases; all these patients had good cosmetic and functional outcomes. Two patients died with lung metastases; one of these patients had local tumour recurrence. Wound healing problems and seroma formations were observed in two patients. Intramedullary nailing was required in one patient for a pathological fracture. Tumour resection for soft-tissue sarcomas combined with microsurgical reconstruction of the soft-tissue defect, preoperative external beam radiation and high dose rate brachytherapy results in a high degree of local control with acceptable complications.

Abstract
Lipomatous tumors range from benign lipomas to high-grade liposarcomas. Liposarcomas are classified into five histologic subtypes: well-differentiated, dedifferentiated, myxoid, round cell, and pleomorphic, which differ in outcomes and patterns of recurrence. Surgical resection is the mainstay of curative treatment; however, large, high grade liposarcomas may benefit from multimodality treatment with chemotherapy and radiation. A histologic-subtype specific nomogram provides accurate survival predictions. Prospective randomized clinical trials will continue to improve our care of patients with liposarcoma.

Abstract
BACKGROUND The aim was to review a single-institution experience of a prospective treatment protocol for soft tissue sarcoma of the extremity and trunk wall, with particular focus on the smallest surgical margin leading to local control. METHODS The study included 270 patients who had surgery for soft tissue sarcoma at Helsinki University Central Hospital between 1987 and 1997. Resection margins were measured prospectively from tumour specimens. Radiotherapy was administered if the smallest margin measured less than 2.5 cm, irrespective of tumour grade. RESULTS With a median follow-up of 6.6 years, the 5-year local control rate was 76.4 per cent. On multivariable analysis, the smallest surgical margin around the sarcoma (after radiotherapy) was prognostic for local control. A margin of at least 2.5 cm was associated with a local recurrence-free rate of 89.2 per cent at 5 years. Tumour size, depth or grade and patient's age had no independent prognostic effect on local control. CONCLUSION Surgical margin had independent prognostic value for local control. A surgical margin of 2-3 cm provided reasonable local control of soft tissue sarcoma, even without radiotherapy. Radiotherapy is recommended for smaller margins, irrespective of tumour grade.

Abstract
PURPOSE To report preliminary results on using intensity modulated radiation therapy (IMRT) as an adjuvant treatment in primary soft tissue sarcoma (STS) of the extremity. METHODS AND MATERIALS Between February 2002 and March 2005, 31 adult patients with primary STS of the extremity were treated with surgery and adjuvant IMRT. Tumor size was >10 cm in 74% of patients and grade was high in 77%. Preoperative IMRT was given to 7 patients (50 Gy) and postoperative IMRT (median dose, 63 Gy) was given to 24 patients. Complete gross resection including periosteal stripping or bone resection was required in 10, and neurolysis or nerve resection in 20. The margins were positive or within 1 mm in 17. Complications from surgery and radiation therapy (RT) were assessed using the Common Terminology Criteria for Adverse Events grading system. RESULTS Median follow-up time was 23 months. Grade 1 RT dermatitis developed in 71% of patients, Grade 2 in 16%, and Grade 3 in 10%. Infectious wound complications developed in 13% and noninfectious complications in 10%. Two patients (6.4%) developed fractures. Grade 1 neuropathy developed in 28% of patients and Grade 2 in 5%. The rates of Grade 1 and 2 joint stiffness were each 19%. Grade 1 edema was observed in 19% of patients and Grade 2 in 13%. The 2-year local control, distant control, and overall survival were 95%, 65%, and 81%, respectively. CONCLUSION Intensity modulated RT appears to provide excellent local control in a difficult group of high-risk patients. The morbidity profile is also favorable, but longer follow-up is needed to confirm the results from this study.

Abstract
Sarcomas are mesenchymal cancers, which, in many cases, have distinctive molecular features. Limb-sparing surgery delivered at specialised sarcoma centres as part of a multidisciplinary approach has become the standard treatment for most patients and usually provides excellent local control. Preoperative treatment with chemotherapy is most common for patients with bone sarcomas. The ideal sequence of surgery and radiation for local management of soft-tissue sarcoma remains controversial on the basis of early versus late treatment complications, although preoperative radiation can provide the best results for improved long-term function. New methods for radiation delivery and tumour sensitisation might provide further improvements. However, metastatic disease is common, and conventional chemotherapy provides for only a narrow therapeutic window outside of a few responsive pathological subtypes. Targeting underlying molecular events in specific sarcomas can provide for dramatic benefits, as has been seen with imatinib treatment for gastrointestinal stromal tumours and dermatofibrosarcoma protuberans. Trials of agents targeting the cell cycle and angiogenesis in soft-tissue sarcomas, and of those targeting osteoclasts in bone sarcomas, are currently underway. Biological data and preclinical studies support trials using inhibitors of hedgehog signalling in chondrosarcoma, inhibitors of wnt/beta-catenin in osteosarcoma and aggressive fibromatosis, and inhibitors of histone deacetylases in synovial sarcoma and Ewing sarcoma. Pharmacogenetic approaches will be needed to identify individual determinants of response and outcome in order to maximise the benefits of targeting specific molecular events and keep side-effects to a minimum. Research in stem-cell biology and nanotechnology holds promise for additional novel treatment options in the future.

Abstract
Neoadjuvant chemotherapy for treatment of soft tissue sarcomas is controversial, and the correlation between local recurrence and survival is unclear. Histologic necrosis is a well-documented predictor of survival in patients with malignant bone tumors; however, the association is unknown in patients with soft tissue sarcomas. We assessed the prognostic significance of tumor necrosis for treatment of soft tissue sarcomas. We retrospectively collected data from 82 patients who received neoadjuvant chemotherapy for treatment of soft tissue sarcomas of the extremities. Patients had wide resections if tumors were high-grade, deep to the investing fascia, and had clear margins. We quantified the amount of necrosis and analyzed the relationship with local recurrence and overall survival. At an average followup of 65 months (range, 24-154 months), the 5-year local recurrence rates for patients with less than 95% and 95% or greater necrosis were 20% and 33%, respectively. The overall 5-year survivorship rates for patients with less than 95% necrosis and 95% or greater necrosis were 82% and 78%, respectively. There was no difference in recurrence-free survival or overall patient survival based on the amount of histologic necrosis. Tissue necrosis from neoadjuvant chemotherapy does not seem to predict outcome in soft tissue sarcomas.

Abstract
BACKGROUND We explored the prognostic meaning of local relapse and surgical margins in adult soft tissue sarcoma of the extremities. METHODS Out of a series of 1017 patients with extremity soft tissue sarcoma treated over 20 years, we picked a group of 238 patients operated on at our institution for their first local relapse: 88 after their primary operation performed at the same center and 150 elsewhere. At operation for relapse, margins were microscopically negative in 77% and 75% of patients, respectively. Median follow-up was 107 months. RESULTS The 10-year mortality rate was 22% in the absence of local relapse, whereas in locally relapsing patients it was 54% and 43%, respectively, for patients first operated on at our institute and for those who were not. The hazard ratio of positive versus negative surgical margins was 1.7 for cause-specific death and 2.1 for distant metastases in patients first operated on at our institute, as opposed to 1.2 and 1.3 for the others. CONCLUSIONS Local relapse was an unfavorable prognostic factor. In the face of a consistent surgical policy for local relapse in a single-institution setting, patients relapsing after the first operation performed at our institution received rescue treatment less frequently than those previously operated on outside a referral center. This is likely due to an inherently higher tumor aggressiveness. In the presence of such a higher aggressiveness, the adequacy of surgical margins at operation for first relapse seemed more critical prognostically. This may have clinical and speculative implications.

Abstract
Doxorubicin-based chemotherapy does not appear to offer a survival benefit to patients who have high-risk primary extremity soft tissue sarcomas, whereas ifosfamide-based chemotherapy does. This benefit is likely histology- and size-specific. Until a less toxic targeted systemic therapy is developed, treatment with ifosfamide should be strongly considered in patients who have high-risk primary extremity soft tissue sarcomas.
