Biau DJ, Ferguson PC, Chung P, Griffin AM, Catton CN, O'Sullivan B, Wunder JS. Local recurrence of localized soft tissue sarcoma: a new look at old predictors. Cancer 2012; 118:5867-77.

Abstract
BACKGROUND The objective of this study was to examine the effect of known predictors of local recurrence of soft tissue sarcoma in a competing risk setting. METHODS The outcome of interest was the cumulative probability of local recurrence per category of relevant predictors, with death as a competing event. In total, 1668 patients with a localized soft tissue sarcoma of the extremity or trunk were included. RESULTS Tumor size (hazard ratio, 3.3), depth (hazard ratio, 3.2), and histologic grade (hazard ratio, 4.5) were the variables that had the most effect on the risk of metastasis and, accordingly, were the most likely to induce competition. Surgical margins (hazard ratio, 3.3), histologic grade (hazard ratio, 2.1), presentation status (hazard ratio, 2.4), and tumor depth (hazard ratio, 1.5) were the variables that had the most effect on the risk of local recurrence. The 10-year cumulative probabilities of local recurrence were markedly different within categories for presentation status (P < .001) and surgical margin status (P < .001). However, because of the competing effect of death, there was little difference in the 10-year cumulative probabilities of local recurrence with regard to tumor depth (12% and 11.4% for deep and superficial tumors, respectively; P = .2), tumor size (10.6% and 13.3% for large and small tumors, respectively; P = .99), or histologic tumor grade (12.6%, 10.7%, and 11.1% for high, intermediate, and low-grade tumors, respectively; P = .17). CONCLUSIONS Because of the competition between local recurrence and death, histologic tumor grade, tumor size, and tumor depth had little influence on the cumulative probability of local recurrence. The authors concluded that local management should be based on presentation status and surgical margins rather than other, previously acknowledged factors.

Abstract
OBJECTIVES We reviewed our institution's experience in treating soft tissue sarcomas of the extremity to identify factors associated with local recurrence, metastasis, and overall survival, to identify patients who may benefit from intensification of therapy. METHODS A retrospective analysis was performed for patients who underwent both limb-sparing surgery and external beam radiotherapy for extremity sarcoma. Those who had gross residual disease or who presented with recurrent or metastatic disease were excluded. The Kaplan-Meier product limit and multivariate Cox regression were used to estimate local failure-free probability, distant failure-free probability, and overall survival along with associations with patient, tumor, and treatment characteristics. RESULTS One hundred eighty-eight patients were included in the analysis. Twenty-five (13%) and 46 (24%) experienced local and distant recurrence, respectively. Patients with high/intermediate-grade tumors [hazard ratio (HR)=5.63, 95% confidence interval (CI): 1.27-24.89, P=0.023] or with multifocally positive margins (HR=4.27, 95% CI: 1.20-15.24, P=0.026) were more likely to fail locally. Those with a preceding local recurrence (HR=8.58, 95% CI: 3.87-19.04, P<0.0001), high/intermediate-grade tumors (HR=5.68, 95% CI: 1.28-25.25, P=0.023), or no secondary reexcision (HR=2.5, 95% CI: 1.09-5.74, P=0.031) were more likely to develop metastasis. Patients with local recurrence (HR=3.6, 95% CI: 1.77-7.29, P<0.001), metastasis (HR=16.0, 95% CI: 7.93-32.31, P<0.0001), or without secondary reexcision (HR=3.2, 95% CI: 1.27-8.09, P=0.014) had decreased overall survival. CONCLUSIONS Patients whose tumor grade or margin status put them at high risk for local failure should be considered for intensification of therapy. Those with a local recurrence should be considered for increased surveillance or systemic therapy, as local failure is associated with subsequent metastasis and decreased survival.

Abstract
PURPOSE To develop a nomogram based on clinicopathologic factors to quantify the risk of local recurrence (LR) after limb-sparing surgery without adjuvant radiation (RT). METHODS Review of our prospective sarcoma database identified 684 patients with primary, nonmetastatic, extremity STS treated with limb-sparing surgery alone between June 1982 and December 2006. No patient received adjuvant radiation or chemotherapy. Age, sex, grade, depth, size, site, margin status and histology were analyzed for prognostic significance with respect to local recurrence rates using Gray's test. Variables which were significant in univariate analysis at the 0.05 level were entered into a multivariate competing risk regression model. On the basis of the multivariate analysis, a nomogram for predicting the 3- and 5-year risk of LR was developed using R libraries cmprsk and QHScrnomo. Concordance index (C-index) was calculated to evaluate the discriminatory power of the prognostic model. RESULTS With a median follow-up of 58 months for censored patients (73 months for all patients), the overall 3- and 5-year actuarial local recurrence rates were 11% and 13%, respectively. Factors included in the nomogram were age (≤ 50 vs. >50), size (≤ 5 vs. >5 cm), margin status (negative vs. positive), grade (low vs. high), and histology (atypical lipomatous tumor/well differentiated liposarcoma vs. other). The STS nomogram predicted the local recurrence rate with a C-index of 0.73. CONCLUSIONS A nomogram for extremity STS that includes age, size, margin status, grade of tumor, and histology predicts the 3- and 5-year risk of local recurrence after limb-sparing surgery in the absence of adjuvant RT.

Abstract
BACKGROUND AND OBJECTIVES Wide excision with a 2-3 cm safe margin is widely-accepted in treating high-grade osteosarcoma. However, a wider margin sacrifices more healthy bone and may jeopardize joint function. We hypothesize that our innovative hemicortical resection for such tumors leads to better joint function without higher recurrence rate. METHODS Between August 2002 and April 2007, six patients of high-grade osteosarcoma were treated with hemicortical resection and biological reconstruction. RESULTS Five tumors were located around the knee and one was located in the distal tibia. The mean tumor size was 20.5 cm(3). The bone defects were reconstructed using recycled autograft in four cases (one by extracorporeal irradiation; three by liquid nitrogen) and structural allograft in two. In an average follow-up of 52 months (24-96), all patients survived without local recurrence or metastasis. All bone grafts incorporated well without mechanical failure or infection. The average Musculoskeletal Tumor Society score was 97.7%. CONCLUSIONS Hemicortical resection for high-grade osteosarcomas located eccentrically in the long bones may be a reliable technique leading to good joint function by preserving surrounding healthy tissues. The functional outcome was encouraging, although long-term follow-up is mandatory to validate. With the advancement of chemotherapy and radiographic three-dimensional imaging, the safe margin in wide excision of high-grade osteosarcoma may be narrowed down in light of joint surface preservation.

Abstract
Purpose To examine the effect of age on the recurrence of soft tissue sarcoma in the extremities and trunk. Patients and Methods This was a multicenter study that included 2,385 patients with median age at surgery of 57 years. The end points considered were local recurrence and metastasis. Cox proportional hazards models were used to estimate hazard ratios across the age ranges with and without adjustment for known confounding factors. Results Older patients presented with tumors that were larger (P < .001) and of higher grade (P < .001). The proportion of positive margins increased significantly as patients age (P < .001), but radiation therapy was relatively underused in patients older than age 60 years. The 5-year cumulative incidences of local recurrence were 7.2% (95% CI, 4% to 11.7%) for patients age 30 years or younger and 12.9% (95% CI, 9.1% to 17.5%) for patients age 75 years or older. The corresponding 5-year cumulative incidences of metastasis were 17.5% (95% CI, 12.1% to 23.7%) and 33.9% (95% CI, 28.1% to 39.8%) for the same groups. Regression models showed that age was significantly associated with local recurrence (P < .001) and metastasis (P < .001) in nonadjusted models. After adjusting for imbalance in presentation and treatment variables, age remained significantly associated with local recurrence (P = .031) and metastasis (P = .019). Conclusion Older patients have worse outcomes because they tend to present with worse tumors and are treated less aggressively. However, there remained a significant increase in the risk of both local and systemic recurrence associated with increasing age that could not be explained by tumor or treatment characteristics.

Abstract
Purpose. The influence of initial inadequate excision (IIE) of soft tissue sarcoma (STS) on local control and overall survival is not well established. It is generally believed that an IIE may have a negative impact on both, despite subsequent treatment by radical surgery and radiotherapy. However, data on local recurrence-free survival/overall survival are conflicting and there are no data on the effect of IIE on overall survival.Patients and methods. A retrospective analysis was made of 86 patients with soft tissue sarcoma of the extremities and trunk after an IIE had been performed due to inappropriate work-up. The minimal follow-up was 7 years. Specimens of the subsequent radical resection were evaluated for residual tumor, grade of tumor and complications of IIE. Endpoints were recurrence-free survival and overall survival.Results. Specimens of the subsequent radical resection showed residual tumor in 66 patients (77%). The most common complication after IIE was hematoma. In both univariate and multivariate analyses, grade II/III tumors and complications after IIE are significant negative prognostic factors for local recurrence-free survival (P = 0.008 and P = 0.002, respectively, in the Cox model). For this survival, three prognostic groups could be formed based on grade, or presence or absence of complications. Adjuvant radiotherapy did not change the rate of local recurrence-free survival. For overall survival, only tumor grade is a significant factor (log-rank test).Conclusion. This retrospective study shows that complications associated with an IIE have a significant negative effect on local control, but not on overall survival, because IIE is often the result of inappropriate work-up before surgery. For better diagnosis and therapy STS should be treated in specialized centers.

Abstract
Despite the clinical and financial implications, there is little evidence about how patients who have been treated for soft tissue sarcoma should be followed up. The purpose of this study was to determine current practice in the United Kingdom. 192 clinicians treating patients with soft tissue sarcoma were surveyed with a postal questionnaire enquiring about frequency and method of follow up and how patients would be followed up in each of 3 clinical scenarios: a patient with a trunk or extremity tumour at low risk of relapse; a patient with a trunk or extremity tumour at high risk of relapse; and a patient with a retroperitoneal or abdominal tumour. 155 (81%) clinicians responded. Clinic visits and X-rays were the most frequently used methods of follow up. Chest CT scans, local site imaging, and blood tests were used infrequently. The intensity and methods of follow up varied with each of the clinical scenarios. There was a seven-to-twenty fold variation in cost between the least and the most expensive regimes. Respondents were generally
supportive of the development of the clinical trial in this area.

Abstract
Despite the fact that soft tissue sarcomas are representing a rare tumor entity with a low incidence rate of about 2-4 per 100,000 per year, they highly require a multimodality therapeutic approach. Based on a reference pathology a complete surgical resection is the first treatment goal. After accomplished R0 resection the local relapse rate can be further decreased by an adjuvant radiotherapy. For primarily irresectable or only partially respectable tumors a neoadjuvant chemotherapy combined with regional hyperthermia should be considered. Patients with metastasized soft tissue sarcomas should receive an anthracyclin-based chemotherapy in a palliative intention. Prognostically more favorable are gastrointestinal stroma tumor, also in advanced stages with metastases, since the tyrosine kinase inhibitors imatinib and sunitinib can induce durable remissions.

Abstract
Background Standard treatment for localized soft tissue sarcoma (STS) is resection plus adjuvant radiotherapy (RTx). In approximately 10% of cases, resection would cause severe loss of function or even require amputation because of the extent of disease. Isolated limb perfusion (ILP) with tumor necrosis factor alpha (TNF-α) and melphalan can achieve regression of the tumor, facilitating limb-saving resection. RTx improves local control but may lead to increased morbidity. Methods In our database of over 500 ILPs, 122 patients with unifocal STS were treated by ILP followed by limb-sparing surgery. All included patients were candidates for amputation. Results Surgery resulted in 69 R0 resections (57%), and in 53 specimens (43%) resection margins contained microscopic evidence of tumor (R1). Histopathological examination revealed >50% ILP-induced tumor necrosis in 59 cases (48%). RTx was administered in 73 patients (60%). Local recurrence rate was 21% after median follow-up of 31 months (2–182 months). Recurrence was significantly less in patients with >50% ILP-induced necrosis versus ≤50% necrosis (7% vs. 33%, P = 0.001). A similar significant correlation was observed for R0 versus R1 resections (15% vs. 28%, P = 0.04). In 36 patients with R0 resection and >50% necrosis, of whom 21 were spared RTx, no recurrences were observed during follow-up. Conclusions In patients with locally advanced primary STS, treated with ILP followed by R0 resection, and with >50% ILP-induced necrosis in the resected specimen, RTx is of no further benefit.

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

Abstract
PURPOSE Myxofibrosarcoma (MFS) is a rare sarcoma with a predilection for multiple local recurrences (LR), for which optimal treatment has not been defined. We reviewed our experience to determine the impact of surgery and radiation therapy (RT) on pattern of recurrence, limb salvage, and overall survival (OS). METHODS AND MATERIALS Between 1995 and 2005, 36 patients with localized intermediate- or high-grade MFS were treated at our institution. Data on clinicopathologic features, treatments, and patient outcomes were reviewed and analyzed. RESULTS Median age was 72.5 years (range, 42-96 years). Median tumor size was 7.5 cm, and 34 tumors (94%) were high grade. All patients underwent surgery at our institution, including re-resections in 20 patients (56%) after initial surgery elsewhere. Margins were microscopically positive in 9 patients (25%). RT was given to 28 patients (78%) pre - and/or postoperatively. After a median follow-up of 3.5 years (range, 0.4-12.4 years), 11 patients (31%) developed LR. There were no significant predictors for LR on univariate analysis, including margin status or use of RT. Limb salvage was ultimately achieved in only 5 of 11 LRs (45%) because of multiple subsequent LRs. Distant recurrence (DR) occurred in 6 patients (17%). Median and 4-year OS were 96 months and 65%, respectively. Seven patients (19%) died of tumor-related causes, 6 of whom had DRs. On univariate analysis, tumor size was associated with OS. CONCLUSIONS Despite aggressive surgery and RT, intermediate- and high-grade MFS are associated with a high rate of LR that adversely affects limb preservation. More aggressive local treatment strategies are necessary.

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
BACKGROUND Adult soft tissue sarcomas (STS) of extremities are prone to recurrence despite apparently complete resection. This study aimed to explore the impact of clinicopathological factors on outcome and to define an "oncological safe margin" in these patients. METHODS A total of 181 patients with extremity STS were enrolled in a retrospective study. The prognostic influence of margin status and other clinicopathological characteristics on local recurrence-free survival (LRFS), distant metastasis-free survival (DMFS), and disease-specific survival (DSS), were examined by univariate and multivariate analyses. The influence of surgical margins on postrecurrence survival (PRS) of patients undergoing reoperation for relapsed lesions during follow-up was analyzed by the Kaplan-Meier method. RESULTS Surgical margin width <10 mm and deep tumor depth at primary operation were consistently statistically significant independent adverse factors for LRFS, DMFS, and DSS. Patients with liposarcoma or low grade tumors had significantly higher chances of achieving adequate margins. Of 83 patients who experienced recurrence or metastasis, 53 (63.9%) received reoperation for their relapsed lesions. Patients who achieved microscopically negative margins (R0) at reoperation had significantly better PRS than those who did not (P < 0.007). Overall, patients with no recurrences had the best DSS, while relapsed patients receiving R0 reoperation had better DSS than those receiving either non-R0 reoperation or no reoperation at all. CONCLUSION Surgical margins prognostically influence survival in both patients undergoing primary surgery and those undergoing reoperation for relapse of extremity STS. In primary surgery, the chance of achieving adequate margin may reflect the underlying aggressiveness of tumors.

Positive surgical margins in soft tissue sarcoma treated with preoperative radiation: is a postoperative boost necessary? Int J Radiat Oncol Biol Phys 2010; 77:1191-7.

Abstract
PURPOSE For patients with an extremity soft tissue sarcoma (STS) treated with preoperative radiotherapy and surgically excised with positive margins, we retrospectively reviewed whether a postoperative radiation boost reduced the risk of local recurrence (LR). METHODS AND MATERIALS A total of 216 patients with positive margins after resection of an extremity STS treated between 1986 and 2003 were identified from our institution's prospectively collected database. Patient demographics, radiation therapy parameters including timing and dose, classification of positive margin status, reasons for not administering a postoperative boost, and oncologic outcome were collected and evaluated. RESULTS Of the 216 patients with a positive surgical margin, 52 patients were treated with preoperative radiation therapy alone (50 Gy), whereas 41 received preoperative radiation therapy plus a postoperative boost (80% received 16 Gy postoperatively for a total of 66 Gy). There was no difference in baseline tumor characteristics between the two groups. Six of 52 patients in the group receiving preoperative radiation alone developed a LR compared with 9 of 41 in the boost group. Five-year estimated LR-free survivals were 90.4% and 73.8%, respectively (p = 0.13). CONCLUSIONS We found that including the postoperative radiation boost after preoperative radiation and a margin-positive excision did not provide an advantage in preventing LR for patients treated with external beam radiotherapy. Given that higher radiation doses placed patients at greater risk for late complications such as fracture, fibrosis, edema, and joint stiffness, judicious avoidance of the postoperative boost while maintaining an equivalent rate of local control can reduce the risk of these difficult-to-treat morbidities.

Nonreferral of possible soft tissue sarcomas in adults: a dangerous omission in policy. Sarcoma 2009; 2009:827912.

Abstract
Introduction. The aim of this study is to compare outcomes in three groups of STS patients treated in our specialist centre: patients referred immediately after an inadequate initial treatment, patients referred after a local recurrence, and patients referred directly, prior to any treatment. Patients and methods. We reviewed all our nonmetastatic extremity-STS patients with a minimum follow-up of 2 years. We compared three patient groups: those referred directly to our centre (group A), those referred after an inadequate initial excision (group B), and patients with local recurrence (group C). Results. The study included 174 patients. Disease-free survival was 73%, 76%, and 28% in groups A, B, and C, respectively (P < .001). Depth, size, and histologic grade influenced the outcome in groups A and B, but not in C. Conclusion. Initial wide surgical treatment is the main factor that determines local control, being even more important than the known intrinsic prognostic factors of tumour size, depth, and histologic grade. The influence on outcome of initial wide local excision (WLE), which is made possible by referral to a specialist centre, is paramount.

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
This study was based on 459 adult patients with deep, high-grade, soft tissue sarcoma of extremities or trunk wall reported to the Scandinavian Sarcoma Group Register (1986-1993). All patients had their definitive surgery for primary tumor at a sarcoma center. The median follow-up was 7.5 (3-12) years. 204 patients are still alive. 68 patients had amputations and 391 underwent limb-sparing surgery. Among 183 patients with intralesional or marginal margins after limb-sparing surgery, 65% had postoperative radiotherapy and 9% of the 198 patients with wide margins. The local recurrence rate after limb-sparing surgery was 26%. The rate with an intralesional or marginal margin was 39% without postoperative radiotherapy versus 24% when radiotherapy was given. It was 25% after a wide margin, and no recurrences were noted among the 10 patients with a compartmental surgical margin. Among patients with a wide margin, a subset fulfilling criteria for a myectomy was defined. The local recurrence rate was 26% among these 62 and there was no advantage of myectomy over other wide margins. More radical surgical margins would improve the local recurrence rate, but this can hardly be achieved in center-operated patients without increasing the amputation rate. Instead, increased use of radiotherapy in all patients with inadequate margins, and to a larger extent in those with wide margins will improve local control.

Abstract
To identify pertinent indicators for oncologic outcomes in assessing surgery in soft tissue sarcomas, only local recurrences are considered here. Functional outcomes and treatment morbidity, equally important end-points for evaluating surgery quality, are less frequently reported and are not taken into account in this review. Herein, we review recent publications reporting indicators of surgery quality in soft tissue sarcoma treatment. Local recurrence-free interval is the major end-point in evaluating the quality of surgery. Disease-free survival should not be used because the risk factors for metastases are different from those for local recurrence. Five-year local recurrence-free estimations for limb and trunk wall sarcoma should be below 20%, and best approach 10%. The risk of local recurrence depends on tumour biology (i.e. grade) and quality of surgery as defined by the quality of margins. Better than margin width as measured on the tumour specimen, margin quality determined consensually between surgeons and pathologists is the best indicator for local outcome. Quality of margin should be expressed according the UICC residual disease definitions (R0: in sano, R1: microscopic residual disease, R2: macroscopic residual disease). Other important indicators for surgery quality are treatment in specialised centres, a planned, organised surgery, and treatment within a multidisciplinary team. Soft tissue sarcoma should also be treated in specialised centres. Surgery quality depends on obtained margins that are determined best by close collaboration between the surgeon and the pathologist.

Abstract
Surgery and radiation therapy are the standard for local tumour control in the treatment of soft tissue sarcoma. Sarcoma recurrence within a previously irradiated area is one of the most problematic therapeutic challenges in soft tissue tumours. Any information on previous therapy needs to be available in detail. In case of recurrent sarcoma not amenable to surgical resection with wide and clear margins, a multimodality therapy needs to be applied. The armamentarium usually looks for a neoadjuvant downstaging of the sarcoma by radiotherapy, chemo-radiotherapy or isolated limb perfusion with all of those strategies bearing benefits, but also specific risks. The potential of repeated radiotherapy and the modality that can be used (intraoperative radiotherapy, brachytherapy) needs to be carefully evaluated. The pathologist saves these major problems in intraoperative frozen section histology or resection margins and thus needs to be aware of the type of cancer cells potentially present within the resection specimen. Plastic and reconstructive surgery to cover the area of re-resection with viable and well-v tissue is absolutely crucial to prevent lymphatic fistula. Thus, adequate treatment of those specific situations usually involves postoperative physiotherapy and a specific rehabilitation, which is extremely important.

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
Soft tissue sarcomas comprise a heterogeneous group of malignancies of mesenchymal origin. Although sarcomas can arise virtually anywhere, the most common primary site is the extremity. The development of metastatic disease poses a major clinical problem because it is seldom amenable to a curative treatment. However, with careful and expert multidisciplinary team selection of patients with metastatic sarcoma-balancing probability of benefit with certain toxicity-a combined multimodality approach may provide hope to a select few for prolonged survival and even cure.

Abstract
BACKGROUND The purpose was to define the rate of local recurrence (LR) and identify prognostic factors for LR in patients with extremity soft-tissue sarcoma (STS) treated with limb-sparing surgery and a pathologically negative re-resection specimen without radiotherapy (RT). METHODS A review of the prospective sarcoma database identified 200 patients with primary, nonmetastatic, extremity STS treated with limb-sparing surgery between June 1982 and December 2002 who had a pathologically confirmed negative re-resection. None of the patients had adjuvant RT. Univariate and multivariate analyses were performed to determine clinicopathologic factors associated with LR. RESULTS With a median follow-up of 82 months the 5-year actuarial LR rate was 9%. Factors associated with higher LR rates on univariate and multivariate analysis were older age, stage III presentation, and histology. The 5-year LR rate was 5% for those<50 compared with 15% for those>or=50 (P=.001). For patients with stage III the LR rate was 26% versus 7% for those with stage I/II (P<.001). On multivariate analysis only age>or=50 (relative risk [RR] 3.3; P=.02) and stage III disease (RR 3.4; P=.01) remained significant predictors for LR. When the cohort of patients was divided into 3 groups based on the number of risk factors present, the 5-year LRs were as follows: no risk factors (stage I/II and<50 years old) 4%, 1 risk factor (stage III or>or=50) 12%, and 2 risk factors (stage III and>or=50) 31% (P<.01). CONCLUSIONS Patients with a pathologically negative re-excision represent a heterogeneous group. Whereas the overall rate of local recurrence at 5 years was 9% for the entire cohort, patients with older age and/or stage III disease had a higher rate of LR. Therefore, treatment decisions especially with regard to adjuvant RT should be individualized and not be based solely on the finding of a negative re-resection.

Abstract
OBJECTIVE To identify prognostic factors in cats with injection-site sarcomas (ISSs). DESIGN Retrospective case series. ANIMALS 57 cats with ISSs. PROCEDURES Medical records of cats were reviewed with regard to sex, age, anatomic site of tumor, tumor size, histologic grade, excision of a primary tumor versus excision of a recurrent ISS, use of excision alone versus excision plus adjuvant therapy, local tumor recurrence, and development of distant metastasis to predict overall survival time (ie, time from tumor excision to death). RESULTS In univariate analyses, local recurrence and development of distant metastasis were significantly associated with survival time in cats. On multivariate analysis, development of distant metastasis remained a significant prognostic factor. Histologic grade was associated with distant metastasis, with cats having grade 3 tumors being significantly more likely to develop metastasis than cats with grade 1 and 2 tumors. Factors associated with local recurrence of ISSs were not identified. CONCLUSIONS AND CLINICAL RELEVANCE The development of distant metastasis, which may occur later during the course of the disease, was identified as a prognostic factor for overall survival time in cats with ISSs. In addition, cats with histologic grade 3 ISSs should be considered for further interventional studies with chemotherapy to prevent the high rate of distant metastasis.

Abstract
BACKGROUND Previous studies have suggested that the prognosis in patients with extremity soft-tissue sarcomas (ESTS) with isolated lymph node (LN) metastases (stage IV) is comparable to that of patients with high-risk ESTS without metastases (stage III). This study was performed to determine the outcomes of patients who underwent aggressive therapy, including lymphadenectomy in patients with LN metastasis from ESTS. METHODS Demographic details, pathology of the primary disease, timing of LN metastasis, and details of the multimodality treatment were obtained from the medical records of 35 patients with nodal metastasis from ESTS who were treated between 1981 and 2003. Survival after the diagnosis of primary disease and LN metastasis was compared with established historical outcomes for patients with American Joint Commission on Cancer (AJCC) stages III and IV ESTS. RESULTS Epithelioid sarcomas (23%) and malignant fibrous histiocytomas (23%) were the most common primary histologic types. Twenty (57%) patients presented with synchronous nodal metastasis. Median follow-up from the time of diagnosis of lymph node metastasis was 48.5 months. The 1-year, 2-year, and 5-year actuarial survival rates in patients with synchronous nodal metastasis after lymphadenectomy and additional therapy were 79%, 62%, and 52%, respectively. In comparison, the 1-year, 2-year, and 5-year actuarial survival rates in patients with metachronous nodal metastasis after lymphadenectomy and additional therapy were 100%, 95%, and 66%, respectively. CONCLUSIONS Patients with isolated regional lymph node metastases who are treated with aggressive approaches, including regional LN dissection, may experience prolonged survival similar to that which more closely approximates the survival seen in patients with stage III disease (5-year survival rate, 50%) rather than the survival seen in patients with stage IV disease (5-year survival rate, 25%). These data lend support for reconsideration of the current AJCC staging system for ESTS.

Abstract
Soft tissue sarcomas are uncommon malignancies that have a high risk of local recurrence despite adequate initial surgery. The aim of follow-up imaging with any malignancy is to detect recurrence promptly so that treatment can be instigated at the earliest possible opportunity. In this review article, we discuss the imaging modalities that can be employed to detect local recurrence following surgery for an extremity soft tissue sarcoma. The role of radiographs, computed tomography, magnetic resonance imaging and positron emission tomography is reviewed followed by a discussion on the imaging modalities useful in the detection of metastatic disease. Finally, we present a robust pathway that is suggested for the follow-up of patients with an extremity soft tissue sarcoma.

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 evaluate whether adjuvant radiotherapy (RT) in extremity and truncal soft-tissue sarcoma (STS) patients with microscopically positive or close margins after excision can achieve comparable local control to that of excision with negative margin plus RT. METHODS AND MATERIALS A total of 150 patients (111 extremity and 39 trunk cases) treated with conserving surgery and adjuvant RT was analyzed. All surgical margins were classified as being a negative margin or a positive or close margin based on pathologic margin width. RT was delivered with a shrinking-field technique in 150 patients (median, 63 Gy). RESULTS All patients were divided into two groups: (A) excision with negative margins plus RT (n = 56) and (B) excision with positive or close margins plus RT (n = 94). Overall, the 5-year local failure-free survival in all patients was 72.9%, and no significant differences were found between the two groups (Group A, 74.7%; Group B, 71.6%). High tumor grade was found to be a significant predictor of local failure. However, Group A was superior to Group B in distant metastasis-free survival (p = 0.02). No significant differences were shown in overall survival between the two groups. CONCLUSIONS In our series, margin status did not predict for LF when adjuvant RT was used. We believe that when adjuvant RT is used, re-resection may not be necessary for selected patients with positive or close pathologic margins in the management of extremity and truncal STS patients.

Abstract
BACKGROUND The objective of this study was to investigate prognostic factors and clinical outcome of myxoid/round cell and pleomorphic liposarcoma. METHODS Three hundred twenty-nine patients with localized myxoid/round cell or pleomorphic liposarcoma who underwent surgery at the Istituto Nazionale per lo Studio e la Cura dei Tumori (Milan, Italy) over 25 years were reviewed. The rates of local recurrence, distant metastases, and survival were studied. RESULTS Two hundred fourteen patients presented with primary disease, and 115 patients had locally recurrent tumors. The disease-specific survival rate was 75% at 10 years, and the local recurrence and distant metastases incidence were 25% and 15%, respectively. Presentation with recurrent disease, tumor size (>10 cm), tumor grade (French Federation of Cancer Centers grade II or III vs grade I), and positive surgical margins were independent predictors of death. Tumor site and radiation therapy also played a role, mostly related to their effect on local outcome. Pathologic grade and histologic subtype influenced distant metastases. Extrapulmonary metastases were associated with poorer postmetastatic disease-specific survival. CONCLUSIONS Myxoid/round cell liposarcomas shared similar prognostic factors with other soft tissue sarcomas and had a relatively good clinical outcome. The presence of >5% of round cell component singled out a group of patients at greater risk of metastases and death but with a broad spectrum of disease aggressiveness. Extrapulmonary metastases were a peculiar pattern of myxoid/round cell liposarcoma that require special consideration for treatment and prognosis.

Abstract
PURPOSE Positive margins (PM) remain after surgery in some soft-tissue sarcoma (STS) patients. We investigated the efficacy of radiation therapy (RT) in STS patients with PM. METHODS AND MATERIALS A retrospective chart review was performed on 154 patients with STS at various anatomic sites with PM, defined as tumor on ink, who underwent RT with curative intent between 1970 and 2001. Local control (LC), disease-free survival (DFS), and overall survival (OS) rates were evaluated by univariate (log-rank) and multivariate analysis of prognostic and treatment factors. RESULTS At 5 years, actuarial LC, DFS, and OS rates were: 76%, 46.7%, and 65.2%, respectively. LC was highest with extremity lesions (p < 0.01), radiation dose >64 Gy (p < 0.05), microscopically (vs. grossly visible) positive margin (p = 0.03), and superficial lesions (p = 0.05). Patients receiving >64 Gy had higher 5-year LC, DFS, and OS rates of 85%, 52.1%, and 67.8% vs. 66.1%, 41.8%, and 62.9% if < or =64 Gy, p < 0.04. OS was worse in patients with G2/G3 tumors with local failure (LF), p < 0.001. Other known prognostic factors, including grade, stage, size, and age (>50), also significantly influenced OS. By multivariate analysis, the best predictors of LC were site (extremity vs. other), p < 0.01 and dose (>64 vs. < or =64 Gy), p < 0.05; the best predictors for OS were size, p < 0.001, gross vs. microscopic PM, p < 0.05, and LF, p < 0.01. CONCLUSION Local control is achieved in most PM STS patients undergoing RT. Doses >64 Gy, superficial location, and extremity site are associated with improved LC. OS is worse in patients with tumors with lesions >5 cm, grossly positive margins, and after local failure.

Abstract
BACKGROUND Leiomyosarcoma of nonvisceral soft tissues is an uncommon malignant tumor; thus, only small numbers of cases have been reported. This study was based on a large series of patients from the Scandinavian Sarcoma Group Register acquired during a 15-year period (from 1986 to 2001). Follow-up information was available for all patients. METHODS The authors analyzed the clinical features of 225 patients with cutaneous, subcutaneous, or deep-seated leiomyosarcoma of the extremities, trunk wall, and superficial parts of the head and neck region to determine the natural course of the disease. Only patients who received their treatment at a specialist sarcoma center were included. Re-evaluation of histopathology was performed. RESULTS The age of the patients (121 women and 104 men) ranged from 20 years to 98 years (median, 70 years), and the tumors ranged in size from 0.6 cm to 35 cm (median, 4.0 cm). Eighty-two percent of the tumors were classified as high grade. The median follow-up for survivors was 5.5 years. The local treatment was adequate in 154 of 206 patients (75%) who were without metastasis at presentation. At 10 years, 84% of the 206 patients with localized disease at presentation were free from local recurrence, 66% remained metastasis free, and 49% were alive. Multivariate analysis showed that higher malignancy grade (P = .006), larger tumor size (P = .003), and deeper tumor location (P = .002) were correlated significantly with decreased metastasis-free survival, inadequate local treatment was correlated with local recurrence (P = .007), and high malignancy grade was correlated with decreased overall survival (P = .007). CONCLUSIONS The long-term prognosis for patients with subcutaneous and deep-seated soft tissue leiomyosarcoma remains poor despite the ability to achieve adequate local control through nonmutilating surgery with or without radiotherapy.

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
Extremity soft tissue sarcomas (STS) represent a rare, heterogeneous malignancy. Surgery is the primary treatment for patients with no evidence of metastatic disease, and for small low-grade superficial tumors in which adequate margins can be obtained, it may be the only therapy indicated. For large, deep tumors or tumors that are close to important neurovascular structures or bone, the addition of radiotherapy to resection has improved local control and increased limb salvage without affecting overall survival. Adjuvant chemotherapy has been an issue of considerable debate. Because 50% of patients with high-risk tumors will develop metastatic disease, effective systemic treatment with chemotherapy is needed. Unfortunately, studies have shown minimal improvement in overall survival when chemotherapy is added to the local treatment of high-risk extremity STS. More recently, a few trials of neoadjuvant chemotherapy consisting of mesna, doxorubicin, ifosfamide, and dacarbazine and high-dose doxorubicin and ifosfamide have shown some early promising results, but at the price of increased toxicity. Targeted therapy has shown some of its best results with gastrointestinal stromal tumors, but so far there has been little success in treating extremity STS. At this time, high-dose adjuvant or neoadjuvant chemotherapy should be given in the setting of a clinical trial to patients with high-risk tumors who can tolerate a potentially toxic chemotherapeutic regimen. The goal of these trials should be to assess new combination therapies, possibly including targeted therapies, for the management of large high-grade, high-risk soft tissue sarcomas.

Abstract
Purpose. Infiltrative microscopical peripheral growth of soft tissue sarcomas (STS) has been shown to be of prognostic importance and preoperative risk stratification could individualize neoadjuvant treatment.
Patients and methods. We assessed peripheral tumour growth pattern on preoperative MRI from 78 STS. The findings were correlated to histopathology and to outcome.
Results. The MRI-based peripheral tumour growth pattern was classified as pushing in 34 tumours, focally infiltrative in 25, and diffusely infiltrative in 19. All tumours with diffuse infiltration on MRI also showed microscopical infiltration, whereas MRI failed to identify infiltration in two-thirds of the microscopically infiltrative tumours. Diffusely infiltrative growth on MRI gave a 2.5 times increased risk of metastases (P = .01) and a 3.7 times higher risk of local recurrence (P = .02).
Discussion. Based on this observation we suggest that MRI evaluation of STS should focus on the peripheral tumour growth pattern since it adds prognostic information of value for decisions on neoadjuvant therapies.

Abstract
BACKGROUND Prospective application of the French Sarcoma Group (FSG) method of surgery reporting in soft tissue sarcoma (STS) in a single centre. METHODS Patients with primary STS of the extremities or trunk wall consecutively operated at the same institution from January 1996 to December 2002 were evaluated for local recurrence (LR). There were 205 patients, with AJCC/UICC stages III and IV in 51% of cases. Resection types according to FSG were R0 in 147, R1 in 53 and R2 in five cases. Radiotherapy was delivered in 163 patients and chemotherapy in 103. Multivariate analysis was performed. Overall five-year survival was 75%. Median follow-up for surviving patients was 53 months. RESULTS Actuarial five-year LR incidence was 13% in 200 patients with gross resection (R0+R1), it was 7% in R0 and 30% in R1 patients (p<0.0001). At univariate analysis, significant prognosticators for LR were age, histotype, tumour invasion, grade and resection type R. At multivariate analysis, resection R1 (relative risk (RR) 4.3, p=0.001) and grade 3 (RR 3.9, p=0.013) independently predicted LR. Combining these two variables produced three prognostic groups for LR: group 0 (no factor, n=70), group 1 (one factor, n=94) and group 2 (two factors, n=36) with five-year LR of 4%, 12% and 39%, respectively (p=6.4x10(-7)). CONCLUSION This first prospective evaluation of surgery reporting in STS evidences a fourfold, highly discriminating difference in LR between resections R0 and R1.

Abstract
Recent publications have permitted to quantify the benefit of radiotherapy in the conservative treatment of soft tissue sarcoma of the limbs. The aim of this review is to focus on aspects of radiotherapy witch influence local control and functional outcome for early and late normal tissue damage. The evaluation of late effects is performed according to Soma-Lent (Subjective-Objective-Management-Analytic-Late Effects of Normal Tissues) classification. About complications, neurological complications are probably under estimated and are related to total dose of radiation therapy.
