Abstract
The aim of this study was to evaluate the outcome of patients with soft tissue sarcoma of the extremity and abdominal wall. This is the retrospective analysis of patients from a prospectively maintained data base from a single institute. We identified 79 patients with intermediate- to high-grade soft tissue sarcomas who were treated at our institute between Jan 2015 and July 2018. Low-grade tumors were excluded. There were 60 males and 19 females with a mean age of 44.6 years. Of the 79 sarcomas, 50 were in the lower limb and 24 in the upper limb and 5 were in abdominal wall. The commonest subtypes were undifferentiated pleomorphic sarcoma (n = 21) and synovial sarcoma (n = 19). Only 9 patients had metastatic disease at presentation. All 79 patients underwent surgical resection with an intent to achieve clear margins. Amputation was done in 19 patients while wide excision of the tumor was done in 60 patients. Adjuvant radiotherapy was given in 49 patients while adjuvant chemotherapy was given in 35 patients. At last follow-up (73 patients), 48 patients are alive without disease, 9 are alive with disease, 12 patients had died of disease, and 4 patients died due to other causes. Overall survival (OS) for 3 year is 77.6%, and estimated mean survival is 55.05 months. Relapse-free surviva (RFS)l at 3 year is 74.3%, and estimated mean RFS is 51.78. The only independent factor that affected the OS was the dimension of primary tumor (p = 0.02). For disease-free survival, the independent factors that affected outcome were stage at presentation (p = 0.04) and dimension of the tumor (p = 0.04). Short-term results shown by this study shows good outcome in patient with intermediate- to high-grade sarcomas when multidisciplinary approach is utilized for the management. Patients who had metastatic disease at presentation did worse than patients who did not.

Abstract
Abstract
Objective. Soft-tissue sarcoma spreads preferentially along muscle fibers. We explore the utility of deriving muscle fiber orientations from diffusion tensor MRI (DT-MRI) for defining the boundary of the clinical target volume (CTV) in muscle tissue. Approach. We recruited eight healthy volunteers to acquire MR images of the left and right thigh. The imaging session consisted of (a) two MRI spin-echo-based scans, T1- and T2-weighted; (b) a diffusion weighted (DW) spin-echo-based scan using an echo planar acquisition with fat suppression. The thigh muscles were auto-segmented using the convolutional neural network. DT-MRI data were used as a geometry encoding input to solve the anisotropic Eikonal equation with the Hamiltonian Fast-Marching method. The isosurfaces of the solution modeled the CTV boundary. Main results. The auto-segmented muscles of the thigh agreed with manually delineated with the Dice score ranging from 0.8 to 0.94 for different muscles. To validate our method of deriving muscle fiber orientations, we compared anisotropy of the isosurfaces across muscles with different anatomical orientations within a thigh, between muscles in the left and right thighs of each subject, and between different subjects. The fiber orientations were identified reproducibly across all comparisons. We identified two controlling parameters, the distance from the gross tumor volume to the isosurface and the eigenvalues ratio, to tailor the proposed CTV to the satisfaction of the clinician. Significance. Our feasibility study with healthy volunteers shows the promise of using muscle fiber orientations derived from DW MRI data for automated generation of anisotropic CTV boundary in soft tissue sarcoma. Our contribution is significant as it serves as a proof of principle for combining DT-MRI information with tumor spread modeling, in contrast to using moderately informative 2D CT planes for the CTV delineation. Such improvements will positively impact the cancer centers with a small volume of sarcoma patients.

Abstract
➤ Soft-tissue sarcomas (STS) in adults comprise a heterogeneous group of tumors of mesenchymal origin that share similar biological patterns of local tumor growth and metastatic dissemination. ➤ The judicious use of imaging studies, biopsy techniques, and pathological evaluations is essential for accurate diagnosis and for planning treatment strategy. ➤ Wide local resection and radiation therapy form the cornerstone of management of high-grade STS. The role of adjuvant radiation therapy is questionable in the management of small (≤5 cm) superficial lesions that can be resected with negative margins. Chemotherapy given to patients who have nonmetastatic, high-grade STS results in varying benefit in terms of local tumor control and overall survival. ➤ Coordinated care by a multidisciplinary team of trained surgeons, medical oncologists, radiologists, radiation oncologists, and pathologists has been documented to improve local tumor control and the overall survival of patients with STS. ➤ Although considerable progress in tumor diagnostics and targeted therapies has been made over the past 2 decades, recommendations and controversies relating to tumor imaging and margins of resection have not changed.

Abstract
Background We recently reported outcomes from a Scandinavian Sarcoma Group adjuvant study (SSG XX group A) conducted on localized and operable high risk soft tissue sarcoma (STS) of the extremities and trunk wall. SSG XX, group B, comprised of patients in a defined cohort with locally advanced STS considered at high risk for intralesional surgery. These patients received preoperative accelerated radiotherapy, together with neoadjuvant and adjuvant chemotherapy. Herein we report the results of this group B. Methods Twenty patients with high-grade, locally advanced and deep STS located in lower extremities (n = 12), upper extremities (5) or trunk wall (3) were included. The median age was 59 years and 14 patients were males. The treatment regimen consisted of 6 cycles of doxorubicin (60 mg/m2) and ifosfamide (6 g/m2), with three cycles given neoadjuvantly, and preoperative radiotherapy (1, 8 Gyx2/daily to 36 Gy) between cycles 2 and 3. After a repeated MRI surgery was then conducted, and the remaining 3 chemotherapy cycles were given postoperatively at 3 weeks intervals. Survival data, local control, toxicity of chemotherapy and postoperative complications are presented. Results Median follow-up time for metastasis-free survival (MFS) was 2.8 years (range 0.3–10.4). The 5-year MFS was 49.5% (95% confidence interval [CI] 31.7–77.4). The median follow-up time was 5.4 years (range 0.3–10.4) for overall survival (OS). The 5-year OS was 64.0% (95% CI 45.8–89.4). The median tumour size was 13 cm, with undifferentiated pleomorphic sarcoma (n = 10) and synovial sarcoma (n = 6) diagnosed most frequently. All patients completed surgery. Resection margins were R0 in 19 patients and R1 in 1 patient. No patients had evidence of disease progression preoperatively. Three patients experienced a local recurrence, in 2 after lung metastases had already been diagnosed. Eleven patients (55%) had postoperative wound problems (temporary in 8 and persistent in 3). Conclusions Preoperative chemotherapy and radiotherapy were associated with temporary wound-healing problems. Survival outcomes, local control and toxicities were deemed satisfactory when considering the locally advanced sarcoma disease status at primary diagnosis. Trial registration This study was registered at ClinicalTrials.gov Identifier NCT00790244 and with European Union Drug Regulating Authorities Clinical Trials No. EUDRACT 2007-001152-39

Advances in image enhancement for sarcoma surgery. Cancer Lett 2020; 483:1-11.

Abstract
The recurrence rate of soft tissue and bone sarcomas strongly correlates to the status of the surgical margin after excision, yet excessive removal of tissue may lead to distinct, otherwise avoidable morbidity. Therefore, adequate margination of sarcomas both pre- and intra-operatively is a clinical necessity that has not yet fully been met. Current guidance for soft-tissue sarcomas recommends an ultrasound scan followed by magnetic resonance imaging (MRI). For bone sarcomas, two plane radiographs are required, followed similarly by an MRI scan. The introduction of more precise imaging modalities may reduce the morbidity associated with sarcoma surgery; the PET-CT and PET-MRI approaches in particular demonstrating high clinical efficacy. Despite advancements in the accuracy in pre-operative imaging, translation of an image to surgical margins is difficult, regularly resulting in wider resection margins than required. For soft tissue sarcomas there is currently no standard technique for image guided resections, while for bone sarcomas fluoroscopy may be used, however margins are not easily discernible during the surgical procedure. Near infra-red (NIR) fluorescence guided surgery offers an intra-operative modality through which complete tumour resection with adequate tumour-free margins may be achieved, while simultaneously minimising surgical morbidity. NIR imaging presents a potentially valuable adjunct to sarcoma surgery. Early reports indicate that it may be able to provide the surgeon with helpful information on anatomy, perfusion, lymphatic drainage, tumour margins and metastases. The use of NIR fluorochromes have also been demonstrated to be well tolerated by patients. However, prior to widespread implementation, studies related to cost-effectiveness and the development of protocols are essential. Nevertheless, NIR imaging may become ubiquitous in the future, carrying the potential to transform the surgical management of sarcoma.

Surgical resection margin classifications for high-grade pleomorphic soft tissue sarcomas of the extremity or trunk: definitions of adequate resection margins and recommendations for sampling margins from primary resection specimens. Mod Pathol 2019; 32:1421-1433. [PMID: 31053757 DOI: 10.1038/s41379-019-0278-9] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/04/2019] [Revised: 03/29/2019] [Accepted: 03/30/2019] [Indexed: 12/13/2022]
Abstract
Adequacy of surgical resection margins for soft tissue sarcomas are poorly defined because of the various classifications and definitions used in prior studies of heterogeneous patient cohorts and inconsistent margin sampling protocols. Surgical resection margins of 166 primary, high-grade, pleomorphic sarcomas of the extremity or trunk were classified according to American Joint Committee on Cancer R and Musculoskeletal Tumor Society categories, as well as by metric distance and tissue composition. None of the cases were treated with neoadjuvant therapy. Multivariable competing risk regression models were evaluated and optimal surgical resection margins for each classification system were defined. Minimum safe tumor clearance was 5 mm without use of adjuvant radiotherapy and 1 mm with adjuvant radiotherapy. Predictive accuracy of margin classification systems was compared by area under receiver-operating characteristic curves generated from logistic regression of 2½-year local recurrence-free survival and other standard tests of diagnostic accuracy. The Musculoskeletal Tumor Society and margin distance classifications performed similarly, both of which showed higher sensitivity and negative predictive value compared to the American Joint Committee on Cancer R classification. The prognostic power of close or positive margins in prediction models significantly increased when six or more slides were submitted for assessment of surgical resection margins. Surgical resection margins for soft tissue sarcoma should be reported using the Musculoskeletal Tumor Society classification or metric distance to the closest resection margin. Musculoskeletal Tumor Society wide/radical margins or tumor clearances of 5 mm (without adjuvant radiotherapy) or 1 mm (with adjuvant radiotherapy) appear to define the minimum safe surgical resection margins necessary to decrease the likelihood of local recurrence of high-grade pleomorphic sarcomas of the extremity or trunk.

Abstract
Objective: To assess the prognostic factors and results of limb sparing surgery and postoperative radiotherapy (PORT) in patients with non-metastatic soft tissue sarcomas (STS) of the extremities. Methods: Between 1980-2007, 114 extremity-located STS treated with PORT were analyzed retrospectively. Tumors were mostly localized in the lower extremities (71,9%). The median radiotherapy (RT) dose was 60.9 Gy. Chemotherapy was administered to 37.7% of the patients. Tumor sizes were between 3-26 cm (median 7 cm). The three most frequent histological types included undifferentiated pleomorphic sarcoma (26.3%), liposarcoma (25.4%), and synovial sarcoma (13.2%). The median follow-up for all patients was 60 months, and 81 months for survivors. Results: The 5- and 10-year local control (LC) rates were 77% and 70.4%, respectively; actuarial survival rates for 5 and 10 years were 71.8% and 69.1%, respectively. Increasing the dose above 60 Gy for all patients and the patients with positive margins demonstrated a clear benefit on 5-year LC (p=0.03 and p=0.04, respectively). Based on multivariate analysis, the addition of chemotherapy and RT dose were independent prognostic factors for LC. A recurrent presentation significantly affects the disease-free survival. Conclusions: PORT for STS of the extremities provides good long-term disease control with acceptable toxicity in a multidisciplinary approach. Level of evidence III, Retrospective study.

Abstract
BACKGROUND Failure to control a periprosthetic joint infection (PJI) often leads to referral of the patient to a tertiary care institution. However, there are no data regarding the effect of prior surgical intervention for PJI on subsequent infection control. QUESTIONS/PURPOSES (1) Is the likelihood of 2-year infection-free survival worse if an initial surgery for PJI was performed before referral to a tertiary care center when compared with after referral for definitive treatment? (2) Is the likelihood of identifying a causal organism during PJI worse if the initial surgery for PJI was performed before referral to a tertiary care center when compared with after referral for definitive treatment? (3) We calculated how many patients are harmed by the practice of surgically attempting to treat PJI before referral to a tertiary care center when compared with treatment after referral to a tertiary care center for definitive treatment. METHODS Among 179 patients (182 TKAs) who were referred for PJI between 2004 and 2014, we retrospectively studied 160 patients (163 TKAs) who had a minimum of 2 years of followup after surgical treatment or had failure of treatment within 2 years. Nineteen TKAs (19 patients) were excluded from the study; 13 patients (7%) had < 2-year followup, three patients had infected periprosthetic fractures, and three patients had infected extensor mechanism reconstruction. Eighty-six patients (88 TKAs, two bilateral [54%]) had no surgical treatment before referral to our institution for PJI management, and 75 patients (75 TKAs [46%]) had PJI surgery before referral. The mean followup was 2.4 ± 1.2 years for patients with PJI surgery before referral and 2.8 ± 1.3 years for patients with no surgery before referral (p = 0.065). Infection-free survival was defined as prosthesis retention without further surgical intervention or antibiotic suppression. During the period, further surgical intervention generally was performed after failure of irrigation and débridement, a one- or two-stage procedure, or between stages of a two-stage reimplantation without documentation of an eradiated infection, and antibiotic suppression generally was used when patients were not medically sound for surgical intervention or definitive implants were placed after the second of a two-stage procedure with positive cultures; these criteria were applied similarly to all patients during this time period in both study groups. Endpoints were assessed using a longitudinally maintained institutional database, and the treating surgeons were not involved in data abstraction. Relative and absolute risk reductions with 95% confidence intervals (CIs) as well as a Kaplan-Meier survival curve with a Cox proportional hazard model were used to evaluate survival adjusting for significant covariates. The number needed to harm is calculated as the number needed to treat. It is the reciprocal of the absolute risk reduction or production by an intervention. RESULTS The cumulative infection-free survival rate of TKAs at 2 years or longer was worse when PJI surgery was performed before referral to a tertiary center (80%; 95% CI, 69%-87%) compared with when no PJI surgery was performed before referral (94%; 95% CI, 87%-98%; log-rank test p = 0.006). Additionally, PJI surgery before referral resulted in a lower likelihood of causative microorganism identification (52 of 75 [69%]) compared with patients having surgery at the tertiary center (77 of 88 [88%]; odds ratio, 2.71; 95% CI, 1.28-4.70; p = 0.006). With regard to the infection-free survival rate of TKAs, the number needed to harm was 7.0 (95% CI, 4.1-22.5), meaning the referral of less than seven patients to a tertiary care center for definitive surgical management of PJI before intervention at the referring hospital prevents one infection-related failure. With regard to the culture negativity in PJI, the number needed to harm was 5.5 (95% CI, 3.3-16.7), meaning the referral of less than six patients to a tertiary care institution for PJI before surgery at the outside hospital prevents the diagnosis of one culture-negative infection. CONCLUSIONS Surgical treatment of a PJI before referral for subspecialty surgical management increases the risk of failure of subsequent surgical management. The prevalence of culture-negative PJI was much higher if surgery was attempted before referral to a tertiary care center when compared with referral before treatment. This suggests that surgical treatment of PJI before referral to a treating center with specialized expertise in PJI compromises the infection-free survival and impacts infecting organism isolation.

Abstract
BACKGROUND Isolated limb perfusion with TNF-alpha and melphalan (TM-ILP) in combination with complete tumor resection is an effective treatment option for non-resectable soft-tissue sarcoma of the extremities, with limb salvage rates greater than 80%. The aim of this study was to assess quality of life (QoL) after TM-ILP, also with regard to long-term survival. METHODS We retrospectively examined 27 patients who had primarily non-resectable soft-tissue sarcoma of the leg and who had undergone TM-ILP and complete tumor resection (with limb-sparing intent) during their follow-up examinations using the Quality of Life Questionnaire (QLQ-C30) and the German Short Musculoskeletal Function Assessment (SMFA-D). The results from the QLQ-C30 were compared to the reference values for the general population, to the "all cancer patients" reference values (both reference values published by the European Organization for Research and Treatment of Cancer (EORTC)), and to the reference values of a historical amputation group from the literature. The results of the SMFA were compared with those from a reference group of healthy individuals. RESULTS Surprisingly, we found that the global health status/QoL in the TM-ILP group was not significantly different from the general population or from patients with amputation, but it was higher than that of patients with cancer in general. Concerning the SMFA, we did find functional impairments in patients after TM-ILP compared to the reference group. With regard to long-term survival, we found no time-dependent deterioration in QoL for longer time intervals after treatment. CONCLUSIONS These results support the use of TM-ILP in limb-sparing multimodal therapy settings from a quality-of-life perspective, but they also encourage further research on this matter.

Abstract
BACKGROUND Tumor necrosis factor alpha (TNF) and melphalan-based isolated limb perfusion (TM-ILP) is one of the most effective treatment modalities for unresectable soft tissue sarcoma (STS) of the extremities. Liposarcomas (LS) are a large and heterogeneous subgroup of STS with different biological behavior and prognoses. The aim of this study was to evaluate LS and the different subentities with respect to their responsiveness towards TM-ILP. METHODS We matched our ILP database with our pathology database to identify patients who received TM-ILP due to STS followed by resection of the residual tumor. We identified 126 patients who matched these inclusion criteria. In this patient group we identified 24 patients with a LS. Histopathological regression was assessed from all resection specimens and was compared between groups: LS vs. non-LS and for myxoid and non-myxoid LS subgroups. RESULTS There were no significant differences in the overall tumor regression comparing non-LS (median 95%, mean 77%) and LS (median 90%, mean 74%). For the subgroup analysis, a higher grade of regression after TM-ILP was found in myxoid-LS (median 95%, mean 79% ± 31.5) compared to the non-myxoid LS (median 75%, mean 72% ± 24.6). Atypical lipomatous tumors (ALT) were less responsive to TM-ILP treatment (median 40%, mean 40%). CONCLUSION The histopathological response of LS toward TM-ILP is equally good compared to non-lipomatous STS. Myxoid LS seem to have a tendency towards a better response to TM-ILP compared to non-myxoid LS and ALT showed the lowest response rate in the liposarcoma subgroup. Furthermore, we found that TM-ILP seems to facilitate successful R0 resection. Due to the low number of cases in the subgroups we advocate further research on this topic.

[PMID: 27014697 PMCID: PMC4781863 DOI: 10.3389/fsurg.2016.00015] [Citation(s) in RCA: 31] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2015] [Accepted: 02/24/2016] [Indexed: 01/12/2023] Open
Abstract
Introduction Solid malignancies at the foot and ankle region are rare and include mainly soft-tissue sarcomas, bone sarcomas, and skin malignancies. Complete surgical resection with clear margins still remains the mainstay of therapy in these malignancies. However, attainment of negative surgical margins in patients with locally advanced tumors of the foot and ankle region may require extensive surgery and could result in loss of extremity function. In these circumstances, plastic surgical techniques can frequently reduce functional impairment and cover soft-tissue defects, particularly in cases of large tumor size or localization adjacent to critical anatomic structures, thereby improving the quality of life for these patients. The aim of this article is to illustrate the various treatment options of plastic surgery in the multimodal therapy of patients with malignant tumors of the foot and ankle region. Materials and methods This article is based on the review of the current literature and the evaluation of the author’s own patient database. Results The local treatment of malignant extremity tumors has undergone major changes over the last few decades. Primary amputations have been increasingly replaced by limb-sparing techniques, preserving extremity function as much as possible. Although defect coverage at the foot and ankle region is demanding due to complex anatomical features and functional requirements, several plastic surgical treatment options can be implemented in the curative treatment of patients with malignant solid tumors in this area. Soft-tissue defects after tumor resection can be covered by a variety of local flaps. If local flaps are not applicable, free flap transfers, such as the anterolateral thigh flap, parascapular flap, or latissimus dorsi flap, can be utilized to cover nearly all kinds of defects in the foot and ankle region. Conclusion Soft-tissue reconstruction in the foot and ankle region is a vital component of limb-sparing surgery. It enables complete resection of locally advanced tumors and subsequent adjuvant radiotherapy. Modern plastic surgical techniques should, therefore, be integrated in the multimodal treatment concept of malignancies in the foot and ankle region.

Eur J Surg Oncol 2016; 42:1057-63. [PMID: 26924784 DOI: 10.1016/j.ejso.2016.02.004] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/21/2015] [Revised: 01/17/2016] [Accepted: 02/02/2016] [Indexed: 11/19/2022] Open
Abstract
BACKGROUND Limb-sparing surgery in combination with radiation therapy is a well-established treatment for high-grade soft tissue sarcomas of the extremities. But selection of cases and optimal sequence of irradiation and surgery still remain controversial. METHODS 769 patients with a high-grade soft tissue sarcoma of the extremities, who underwent a limb-sparing surgery, were retrospectively reviewed. Group 1 (N = 89) was treated with neo-adjuvant radiation therapy, group 2 (N = 315) with adjuvant irradiation and group 3 (N = 365) with surgery alone. RESULTS After a mean follow up of 45 months 95 local recurrences occurred resulting in a local recurrence-free survival of 83.2% after 5 years and 75.9% after 10 years. Contaminated surgical margins (Odds ratio: 2.42) and previous inadequate surgeries (Odds ratio: 1.89) were identified as risk factors for failed local control. Neo-adjuvant radiation therapy provides the best local recurrence-free rate for 5 years (90.0%), whereas after 10 years (78.3%) adjuvant irradiation showed better local control. The metastatic-free rate was independent from achieved surgical margins (p = 0.179). Group 1 showed the highest rate of revision surgery (9.0%), followed by group 3 (5.5%) and group 2 (4.4%) (p = 0.085). However, the rate of irradiation-correlated side effects was higher in group 2 (15.2%) than in group 1 (11.2%) (p = 0.221). CONCLUSION Surgery has to be effective for successful local control and remains the mainstay of the treatment in combination with neo-adjuvant as well as adjuvant irradiation. In really wide or even radical resections the benefit of radiation therapy can be discussed as the irradiation induced side effects are not negligible.

Long-term outcome after local recurrence of soft tissue sarcoma: a retrospective analysis of factors predictive of survival in 135 patients with locally recurrent soft tissue sarcoma. Br J Cancer 2014; 110:1456-64.

Abstract
BACKGROUND The aim of this study was to identify prognostic indicators of survival in patients with locally recurrent soft tissue sarcoma (STS) through a long-term follow-up. METHODS We retrospectively assessed the relationship between post-recurrence survival (PRS) and potential prognostic factors in 135 patients who had experienced local recurrence, which was suitable for further surgical treatment. The median follow-up time after initial recurrence was 12.3 years (95% confidence interval (CI): 10.4-14.2 years). RESULTS The 5-year estimate of the PRS rate was 53.1% (95% CI: 44.3-61.2%) for the entire series. Patients with negative margins after the final surgery experienced improved survival compared with patients with positive margins (5-year survival: 46.7% (35.2-57.5%) vs 35.5% (23.4-47.8%); P=0.01). In a multivariate analysis, the significant prognostic indicators for PRS were histologic grade, tumour site, time to initial recurrence, the number of recurrences and the surgical margin status attained at the last resection. CONCLUSIONS Complete surgical resection with microscopically clear margins is desirable in patients with locally recurrent STS. However, when achieving clear surgical margins will require major functional impairment of the extremity, a radical surgical approach should be weighed for the patient in each case.

Abstract
Clinical positron emission tomography (PET)/magnetic resonance imaging (MRI) acquisition protocols may improve the evaluation of soft tissue sarcomas (STS) prior to surgical planning. We examined two patients with lower extremity STS using a Siemens Biograph mMR PET/MRI scanner and the glucose analogue 18F-fluoro-deoxyglucose (FDG). We investigated clinically relevant tumor volumes and evaluated the relations to skeletal periosteum and nerve bundles. The patient scans suggest that FDG PET/MRI improved the edge detection, and invasion of tumor tissue into important adjacent anatomical structures can be evaluated. FDG PET/MRI also provided additional information compared to conventional Gadolinium enhanced MR imaging. The findings were proven by subsequent pathological examination of the resected tumor tissue. In the future, clinical FDG PET/MRI may be an important modality for preoperative planning, including radiation therapy planning in patients with STS.

Abstract
BACKGROUND Whether to preserve or sacrifice critical structures (bone, major vessels and major nerves) adjacent to soft tissue sarcomas is still controversial. Referring to characteristic imaging and intraoperative findings, we perform planned preservation surgery for these critical structures. The aim of this study was to investigate the clinical outcome of soft tissue sarcomas adjacent to critical structures and to validate this procedure. METHODS Of 202 cases of soft tissue sarcomas surgically treated at our department of orthopedic surgery from 2004 to 2010, 57 cases (28 %) whose tumors were adjacent to the critical structures were studied. There were 36 men and 21 women. In 32 cases critical structures were preserved, and in 25 resected together with the tumor. The oncological outcome and histological surgical margin were analyzed. RESULTS The overall survival and local recurrence-free survival rates at 5 years were 75.9 and 83.2 %. In 26 of the 32 (81 %) preserved cases histologically the surgical margin was negative, and in 17 (53 %) radiotherapy could be avoided. Neither overall survival (p = 0.9669) nor local recurrence-free survival (p = 0.7819) differed significantly between two groups. CONCLUSIONS When soft tissue sarcomas are located adjacent to bone or major vessels, by meticulously detaching the periosteum or neurovascular sheath referring to characteristic imaging and intraoperative findings, a histologically negative surgical margin can be achieved in the majority, allowing avoidance of postoperative radiotherapy. Planned preservation surgery provided no significant adverse effect on survival or local recurrence rates, validating this procedure.

Abstract
BACKGROUND Core needle biopsies of sarcomas allow a diagnosis in a high percentage of patients with few complications. However, it is unclear whether the tract needs to be excised to prevent recurrences. QUESTIONS/PURPOSES We therefore determined the rates of recurrence and metastases in patients with Stage III extremity sarcomas, who underwent wide local resection without excision of the needle tract and also received adjuvant treatment. METHODS We retrospectively reviewed 59 adult patients with deep, larger than 5 cm, high-grade soft tissue sarcomas of the upper or lower extremity treated between January 1999 and April 2009. All the patients underwent a core needle biopsy. Resection was performed with wide margins. The biopsy tract was not resected during the definitive surgery. Fifty-seven patients (97%) received preoperative and/or postoperative radiation, whereas 49 patients (83%) received chemotherapy. Local recurrence and distant recurrence rates were determined. The minimum followup was 24 months (median, 56 months; range, 24-122 months). RESULTS The local recurrence rate was 9%. Fifteen patients (25%) developed metastasis after diagnosis. Seven of the 59 patients (12%) had microscopic positive margins at resection. CONCLUSIONS Our data demonstrate no increase in local recurrence rates or rates of metastatic disease compared with previously published studies when resection of the core biopsy tract was not performed. LEVEL OF EVIDENCE Level IV, therapeutic study. See the Guidelines for Authors for a complete description of levels of evidence.

Abstract
Soft tissue sarcomas have a mortality rate of 40% to 60%, with local recurrence being a poor prognostic factor for overall survival. Three-percent nondiluted hydrogen peroxide is hypothesized to be an effective local adjuvant. The purpose of this study was to identify risk factors for local recurrence in high-grade soft tissue sarcomas and to determine whether using hydrogen peroxide as a local adjuvant reduced the risks of local recurrence and surgical-site infection. Retrospective data were collected for 106 patients surgically treated for high-grade soft tissue sarcomas between 2002 and 2010. The primary endpoint was local recurrence. Eighteen (16.98%) cases of local recurrence occurred. Predictors of local recurrence were margin status, estimated blood loss, and histology (ie, malignant peripheral nerve sheath tumor), with hazard ratios of 4.44 (95% confidence interval [CI], 1.32-14.95), 1.19 (95% CI, 1.06-1.35), and 9.21 (95% CI, 2.11-40.16), respectively. Hydrogen peroxide yielded a statistically insignificant improvement in local recurrence, with a hazard ratio of 0.81 (95% CI, 0.27-2.48) and a reduced risk of surgical site infection, with a hazard ratio of 0.52 (95% CI, 0.15-1.81). Margin status, increased blood loss, and histologic subtype are associated with increased local recurrence risk. Using hydrogen peroxide improved local control and infection rates, but the difference was not statistically significant.

Abstract
BACKGROUND Fine-needle aspiration biopsy (FNAB) is an emerging technique for diagnosis of bone and soft tissue lesions. While multiple studies have demonstrated efficacy, cost-effectiveness, and convenience, none have attempted to determine if the modality leads to an increased rate of local recurrence. Our objective was to determine whether FNAB could be linked to an increased rate of local recurrence. METHODS We reviewed a database containing records of 388 patients who underwent FNAB without surgical biopsy tract excision between September 2002 and December 2006 in the orthopedics department at our institution. After application of rigid criteria to minimize confounding variables, 20 patients were retrospectively examined for local recurrence and distant metastasis. RESULTS In this cohort, no local recurrences were seen over a mean follow-up of 45 months. Fifteen percent of our patients developed one or more distant metastases over the same time interval. Our experience offers preliminary evidence for the safety of this method. CONCLUSIONS While further studies are needed, our data combined with already reported studies on efficacy, cost-effectiveness, and convenience are encouraging for expanding the use of FNAB in the diagnosis of bone and soft tissue tumors.

Abstract
We report the suitability of free flap reconstruction in defects around the knee joint caused by soft tissue sarcoma (STS) excisions. The importance of collateral ligament reconstruction is also evaluated.Between years 1993 and 2005, 15 STS patients having a STS at the knee area with the need for free flap were treated in Helsinki University Hospital. Eleven musculocutaneous latissimus dorsi, 3 fasciocutaneous anterolateral thigh flaps, and 1 osteomusculocutaneous latissimus dorsi were used. The reconstruction of collateral ligaments was performed for 7 patients, 4 medial and 3 lateral; 6 with bone-tendon-bone grafts from patellar tendon and 1 with pes anserinus tendon transposition.There was no postoperative mortality. One flap was lost. Five patients needed debridement for minor wound complications. The mean follow-up time was 64 months. There were no local recurrences. Distant metastasis developed after the operation in 5 patients. Of these, 2 patients with solitary soft tissue metastasis were operated, and they are disease free. At 5 years 79% were disease-free. One patient with medial collateral reconstruction had recurrent patellar displacement and needed further operations; another with lateral collateral ligament and posterior capsular excision, that was not reconstructed, had lateral instability of the knee and needed orthosis.Free flap for STS of the knee is a reliable method. Patients can be operated with wider marginals and prognosis is good. Ligament reconstruction can be performed simultaneously, if collateral ligaments are excised.

Abstract
BACKGROUND The aim was to study the clinicopathological characteristics, treatment, and outcome of liposarcoma in an unselected, population-based patient sample, and to establish whether treatment was according to the Scandinavian Sarcoma Group (SSG) treatment guidelines. METHODS The SSG Pathology Board reviewed 319 liposarcoma cases reported between 1986 and 1998. After the review, 237 patients without metastasis were analyzed for local recurrence rate in relation to surgical margins, radiotherapy, occurrence of metastasis, and survival. RESULTS Seventy-eight percent of the patients were primarily operated on at a sarcoma center, 45% with wide margins. All patients operated on outside the center had nonwide margins. Low-grade lesions constituted 67% of cases. Despite nonwide surgery, only 58% of high-grade lesions were treated with postoperative radiotherapy. The risk of local recurrence after nonwide surgery, without irradiation, was 47% for high-grade lesions. The estimated 10-year, local recurrence-free and metastasis-free survival in the low-grade group was 87% and 95%, respectively. In the high-grade group, it was 75% and 61%, respectively. Independent adverse prognostic factors for local recurrence were surgery outside a sarcoma center and histological type dedifferentiated liposarcoma. For metastases, they were old age, large tumor size, high grade, and histological type myxoid liposarcoma with a round cell component. Radiotherapy showed significant effect on local recurrence rate for the same grade and margin. CONCLUSIONS Patients with liposarcoma should be treated at specialized centers. Postoperative radiotherapy decreases the local recurrence rate. To maintain quality and provide support for further trials, reporting to quality registers is crucial.

Abstract
PURPOSE Adjuvant radiotherapy has during the past decades become increasingly used in the treatment of localized soft tissue sarcoma. We evaluated the effect of radiotherapy (RT) on local recurrence rates (LRRs) in Scandinavia between 1986 and 2005. METHODS AND MATERIALS A total of 1,093 adult patients with extremity or trunk wall soft tissue sarcoma treated at four Scandinavian sarcoma centers were stratified according to the treatment period (1986-1991, 1992-1997, and 1998-2005). The use of adjuvant RT, quality of the surgical margin, interval between surgery and RT, and LRR were analyzed. The median follow-up was 5 years. RESULTS The use of RT (77% treated postoperatively) increased from 28% to 53%, and the 5-year LRR decreased from 27% to 15%. The rate of wide surgical margins did not increase. The risk factors for local recurrence were histologic high-grade malignancy (hazard ratio [HR], 5), an intralesional (HR, 6) or marginal (HR, 3) surgical margin, and no RT (HR, 3). The effect of RT on the LRR was also significant after a wide margin resection and in low-grade malignant tumors. The LRR was the same after preoperative and postoperative RT. The median interval from surgery to the start of RT was 7 weeks, and 98% started RT within 4 months. The LRR was the same in patients who started treatment before and after 7 weeks. CONCLUSION The results of our study have shown that adjuvant RT effectively prevents local recurrence in soft tissue sarcoma, irrespective of the tumor depth, malignancy grade, and surgical margin status. The effect was most pronounced in deep-seated, high-grade tumors, even when removed with a wide surgical margin.

BACKGROUND Soft-tissue sarcomas frequently rest in contact with bone. The purpose of the study was to evaluate the risk of local recurrence for sarcomas adjacent to bone and to determine whether the periosteum provides an adequate margin of resection. METHODS Fifty patients with soft-tissue sarcomas abutting bone were treated at a single institution between 1990 and 2004. All patients had high-grade, T2 (>5 cm), nonmetastatic disease in the lower extremity. Bone contact was verified by preoperative magnetic resonance imaging (MRI) and/or computed tomography (CT) scans. Forty-three of 50 patients received preoperative radiation with a mean dose of 50 Gy. In 11 cases a composite resection of bone and soft tissue was performed. In 39 cases the excision involved only soft tissue. RESULTS True bone invasion was verified by histopathologic examination in 3 of 50 cases (6%). Local recurrence in the soft tissues developed in 8 of 50 (16%) patients. In no case did the recurrence involve destruction of cortical bone or erosion into bone. The recurrent tumor resided against the region of previous bone contact in 1 of 8 cases. There was no statistically significant difference in local recurrence between patients who had composite bone resection and patients who had soft-tissue resection only (P = .87). CONCLUSIONS Relatively few sarcomas are able to penetrate cortical bone. Composite bone and soft-tissue resections are indicated primarily for frank bone invasion. In the absence of this, the periosteum is an adequate surgical margin for sarcomas treated with wide excision and radiation.

Abstract
Soft tissue sarcomas (STS) are particularly rare malignancies that constitute less than 1% of all malignancies. In recent years, prognostic clinical factors have been defined that help to stratify patients regarding their risk for local and distant recurrence and death from disease. Tumor grade, size, depth, completeness of resection, and presentation status are among the independent prognostic factors. At present, the treatment of these tumors constitutes a wide or marginal excision, adequate primary reconstruction, and radiotherapy. Surgery has generally been recommended as the primary method of treatment for achieving local control. Modern reconstructive surgery, especially musculocutaneous, either pedicle or free flaps, has made more extensive resections possible, while providing acceptable cosmetic and functional results. This study deals with our experience in the treatment of resectable STS with selective combination of treatment modalities.

Abstract
During the years 1974 to 2003, a total of 46 cases of malignant tumors at the site of total hip arthroplasty, 41 sarcomas, 4 lymphomas, and 1 epidermoid carcinoma, have been reported in the Western literature. Soft tissue sarcomas occurred in 31 and bone sarcomas in 10 cases. Malignant fibrous histiocytoma was the most common in 20 (65%) of all soft tissue sarcomas. The patients with malignant tumors had been operated on more often for secondary osteoarthritis and had more local complications than those in ordinary total hip arthroplasty series. Primary osteoarthritis was the indication in 63% and secondary osteoarthritis in 37% of the 38 reported cases. Tumor developed after 8 (17%) revisions. Deep infection complicated 4 (9%) of the cases. Four cases (9%) were preceded by a precondition for cancer, 2 postradiation necroses of the femoral head, 1 chronic sinus, and 1 Mafucci syndrome. Mean age of the patients at the time of first implantation was 59 years (range, 24-79 years). The mean latent period was 6 years (range, 0.5-20 years) from the first operation. Longer latency period did not correlate positively with the cancer risk. Sarcomas were highly aggressive. Of the 31 reported patients, 24 (77%) died within 1 year after the diagnosis. The number of reported sarcoma cases is low considering the total population behind the cases. In addition, one observed local sarcoma from Nordic cohorts was less than expected. Chronic, particle-induced inflammation around the prosthesis does not seem to increase the risk for carcinogenesis.

Isolated Limb Perfusion With Tumor Necrosis Factor α and Melphalan for Locally Advanced Soft Tissue Sarcoma: The Value of Adjuvant Radiotherapy. Ann Surg Oncol 2006; 13:518-24.

Abstract
BACKGROUND The aim was to investigate the value of adjuvant radiotherapy for locally advanced soft tissue sarcoma after hyperthermic isolated limb perfusion (ILP) with tumor necrosis factor alpha and melphalan followed by limb-saving surgery. METHODS From 1991 to 2003, 73 patients (median age, 54 years; range, 14-80 years) underwent 77 ILPs, followed by resection in 68 patients (93%). Radiotherapy was administered in case of marginally or microscopically positive resection margins. Local recurrences were scored and calculated according to the Kaplan-Meier method and log-rank test. RESULTS After residual tumor mass resection, 58% received radiotherapy (external beam radiotherapy [EBRT]+ group), and 42% did not (EBRT- group). The median follow-up was 28 months (range, 2-159 months). A significantly better local control rate was observed in the EBRT+ compared with the EBRT- group (P<.0001). When only R0 resections in patients without metastasis were considered, the significance remained between groups (P=.0003). In the EBRT- group, an R1 or R2 resection resulted in earlier relapse of local disease compared with R0 resections (P=.0475). CONCLUSIONS Adjuvant EBRT reduces the risk for local recurrence after delayed resection in soft tissue sarcoma patients treated with ILP and tumor necrosis factor and is indicated when resection margins are close or microscopically positive. It also seems beneficial after an R0 resection.

Abstract
Nearly all bone and soft tissue sarcomas will require surgical management. Early consultation with a surgeon who is experienced in sarcomas, before a biopsy is performed, will avoid potential errors that may complicate subsequent surgery. Advances in imaging, neoadjuvant therapies, and reconstructive techniques have improved the ability to resect adequately most bone and soft tissue sarcomas. The use of oncologic and functional outcomes assessment tools facilitates the development of improved treatments for sarcoma patients. Results from major centers reveal that most patients who have a nonmetastatic bone or soft tissue sarcoma will survive 5 years after surgery when combined with either chemotherapy or radiation.

Preoperative Chemoradiotherapy (Modified Eilber Protocol) Provides Maximum Local Control and Minimal Morbidity in Patients With Soft Tissue Sarcoma. Ann Surg Oncol 2005; 12:646-53.

Abstract
BACKGROUND Local recurrence rates of 15% to 30% after treatment of soft tissue sarcoma (STS) are still common but unacceptable. Our hypothesis was that a refined neoadjuvant chemotherapy and radiation protocol (modified Eilber protocol) improves local control rates while minimizing major morbidity. METHODS Consecutive patients with STS deep to the fascia of the extremity or trunk during 1984 to 1996 were treated with 3 days of doxorubicin (30 mg/day) and sequential radiation (300 cGy/day for 10 days). Wide excision with limb preservation was performed 4 to 8 weeks after radiation completion. Treatment complications, margins, local recurrence, and survival were prospectively documented. RESULTS Of 75 patients, 66% had tumors >5 cm, and 71% were grade 2/3. In eight patients, negative margins were not achieved, and four of these had amputation (95% limb salvage). Three of the remaining four had local recurrence with a 5- and 7-year actuarial local control rate of 50% and 25%, respectively. In contrast, of the 67 patients with negative margins, a local control rate of 97% at 5 years and 94% at 7 years and an overall survival of 63% were achieved. Although margin (P = .001) and stage (P = .035) were correlated, these were not significant on multivariate Cox regression analysis. Risk factors for death included tumor stage (hazard ratio, 1.54; P = .001) and tumor grade (hazard ratio, 1.4; P = .02). Three patients (4%) required reoperation for tissue loss, and eight patients (10.6%) developed minor wound complications. CONCLUSIONS This modified Eilber protocol seems to maximize local control and minimize major wound complications for extremity/truncal STS.

Abstract
The objective of this retrospective follow-up study was to evaluate the outcome of patients with soft-tissue sarcoma treated by the authors' protocol, which consists of a selective combination of conservative surgery and radiotherapy. Patients who relapsed were especially evaluated to improve treatment results. The authors examined 80 patients with local soft-tissue sarcoma in the upper extremity referred to their multidisciplinary group. Fifteen patients were referred for first or subsequent local recurrence, and 65 patients were treated for primary tumor. The goal of treatment was local control and preservation of a functional limb. Wide excision was attempted. If the margin was less than 2.5 cm, postoperative radiotherapy was administered. Eighty-five percent of the patients were treated by limb salvage. Thirty patients needed reconstructive procedures such as pedicled (20 patients) or free flaps (10 patients). No free flaps were lost. The 5-year disease-specific overall survival rate was 75 percent, the local recurrence-free survival rate was 79 percent, and the metastasis-free survival rate was 68 percent. In univariate analysis, prognostic factors for local recurrence were extracompartmental site; for development of metastases, large size and extracompartmental site; and for decreased disease-specific overall survival, large size and extracompartmental site. Intramuscular, cutaneous, and subcutaneous tumors had a 5-year local control rate of 100 percent, and extracompartmental tumors had a local control rate of 69 percent. Extracompartmental tumors clearly have the worst prognosis and should be the main target for improving treatment strategies. After exclusion of patients with inadequate treatment according to the authors' protocol, the local control rate at 5 years was 90 percent. Strict adherence to treatment protocol should be practiced.

Abstract
Further advantages in the treatment of soft-tissue sarcomas will only be achieved by tailoring the adjuvant therapy after surgery. The photochemically directed release of macro-molecules from endosomes and lysosomes into the cytosol is a novel technology, named photochemical internalization (PCI), that has been evaluated for treatment of sarcoma cells in vitro. Two human synovial sarcoma cell lines (SW 982 and CME-1) were treated with the photosensitizer meso-tetraphenylporphine with two sulfonate groups on adjacent phenyl rings (TPPS2a) and a plasmid encoding enhanced green fluorescent protein (EGFP) complexed to poly-L-lysine to investigate the influence of PCI on gene transfer and with 5 micrograms/mL gelonin to investigate PCI of a Type-I ribosome-inactivating protein toxin. In addition, both cell lines were transduced with an Adenovirus serotype 5 encoding the Escherichia coli lacZ gene (AdHCMV-lacZ, expressing beta-galactosidase) and treated with TPPS2a and light to evaluate the effect of PCI on the transduction rate. Photochemically induced transfection with the reporter gene EGFP in CME-1 cells increased from 0% of cells at no light to 40% of the cells after 60 s of light exposure. In contrast, the SW 982 cells showed no enhanced expression of the gene. The fraction of virally transduced cells was about doubled in both cell lines by means of PCI, although the transduction was more efficient in the CME-1 cells. Both cell lines became up to four-fold more sensitive to light when combining photochemical treatment with gelonin incubation. Our experiments showed that PCI induced the endocytic escape of therapeutic substances in cells derived from human soft-tissue sarcomas.
