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
Surgical intervention is the mainstay treatment for soft tissue sarcomas (STSs). The significance of adjuvant and neoadjuvant therapies, such as chemotherapy, radiation, and isolated limb perfusion, remains under controversial discussion. The goal of this review is to discuss the effects of the aforementioned treatment modalities and their timing of application in plastic surgery techniques. Furthermore, options of reconstruction in cases of complications caused by adjuvant and neoadjuvant therapies are discussed. When compared with adjuvant radiation, neoadjuvant treatment can reduce negative side effects such as fibrosis and edema because radioderma can be removed during the subsequent surgical procedure. Furthermore, there have not been any reports of negative effects of neoadjuvant radiation on microsurgical procedures. However, the dose of neoadjuvant radiation correlates with increased risks of impaired wound healing postoperatively. Thus, a patient-specific approach to decide whether radiation should be performed adjuvant or neoadjuvant is necessary. Preoperative irradiation should be considered in cases where functional structures are exposed after tumor resection, in order to ensure the best possible functionality. Adjuvant radiation should be considered in all other cases because of its known superior wound healing. As for chemotherapy, no negative influence of its use adjuvant or neoadjuvant to reconstructive procedures, such as local or free flaps, has been reported. Lastly, small sample size studies have not shown increased risks of microsurgical failure or wound complications after isolated limb perfusion. The findings of this review suggest that the chronological order of the discussed therapeutic approaches is not a decisive factor in the surgical outcome of reconstructive procedures for STS.

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
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
Background. There remains controversy on the routine use of chemotherapy in localized SS. Methods. The records of 87 adult (AP) and 15 pediatric (PP) patients with localized SS diagnosed between 1986 and 2007 at 2 centres in Toronto were reviewed. Results. Median age for AP and PP was 37.6 (range 15–76) and 14 (range 0.4–18) years, respectively. 65 (64%) patients had large tumours (>5 cm). All patients underwent en bloc surgical resection resulting in 94 (92.2%) negative and 8 (7.8%) microscopically positive surgical margins. 72 (82.8%) AP and 8 (53%) PP received radiotherapy. Chemotherapy was
administered to 12 (13.8%) AP and 13 (87%) PP. 10 AP and 5 PP were evaluable for response to
neoadjuvant chemotherapy, with response rate of 10% and 40%, respectively. 5-year EFS and OS was
69.3 ± 4.8% and 80.3 ± 4.3%, respectively, and was similar for AP and PP, In patients with tumors >5 cm, in whom chemotherapy might be considered most appropriate, relapse occurred in 9/19 (47%) with
chemotherapy, compared to 17/46 (37%) In those without. Conclusions. Patients with localized SS have a
good chance of cure with surgery and RT. Evidence for a well-defined role of chemotherapy to improve
survival In localized SS remains elusive.

Abstract
In more than one-third of patients with a histological high-grade malignant soft tissue sarcoma metastasis develops despite local control of the primary tumour. Hence, adjuvant chemotherapy is increasingly used for these relatively chemoresistant tumours which requires improved prognostication to exclude low-risk patients from overtreatment. We assessed the value of stepwise prognostication in a series of 434 histological high-grade STS of the extremity and trunk wall. Vascular invasion was used as the first discriminator whereafter the risk factors tumour necrosis, size (>8cm) and infiltrating growth pattern were used to discriminate high- and low-risk tumours. We identified a high-risk group with a cumulative incidence of metastasis >0.4 at 5 years, and a low-risk group, comprising half of the tumours, with a cumulative incidence of metastasis <0.15. The model was validated in an independent material of 175 patients. This model improved prognostication in STS and is of value for identifying patients who probably should not receive adjuvant chemotherapy.

High incidence of metastatic disease in primary high grade and large extremity soft tissue sarcomas treated without chemotherapy. BMC Cancer 2006; 6:160.

Abstract
BACKGROUND The risk of metastasis and the survival in patients with primary extremity soft tissue sarcomas is worse when tumour size is large and the grade of malignancy is high. Such tumours may receive chemotherapy and/or radiation therapy (RTX) for optimising local control. Irradiation can either be applied preoperatively or after tumour resection. The question arises if the kind of RTX in the absence of chemotherapy influences the outcome concerning local control, metastatic disease, survival and complications. METHODS We retrospectively reviewed the clinical outcome of 233 patients with a primary extremity soft tissue sarcoma treated between 1990 - 2000 with a mean follow-up of 35.8 (4-120) months in our institute. 41 patients had high grade, deep and large tumours (>8 cm), an AJCC stage III (no evidence of metastasis prior to treatment) and were treated with limb salvage surgery and irradiation but stayed without additional chemotherapy. Two groups of patients were compared: the first group received postoperative RTX after tumour resection (n = 33); the second group was treated with preoperative RTX (n = 8). Both groups did not differ concerning clinical parameters. We analysed primary and secondary outcomes. RESULTS 56% (23/41) of the population developed metastatic disease, 24% (10/41) local recurrence. The risk of metastasis was higher in the group with preoperative irradiation (p = 0.046). The overall (p = 0.0248) and relapse free survival (p = 0.104) were worse in this group. The delay to tumour resection amounted 8 weeks on average in the preoperative group. Local control was not different (p = 0.38) in both study groups. Wound infections and other combined therapy related complications were equally distributed (p = 0.22). CONCLUSION Without chemotherapy there remains a high risk of metastasis in AJCC grade 3 patients. In high risk patients treated without chemotherapy the elapsed time to tumour resection after preoperative radiation might contribute to the development of metastasis. This outcome may support the thesis that a combination of RTX and offensive multimodal treatment protocols is advantageous in such a subset of patients.

Abstract
BACKGROUND Most staging systems for soft tissue sarcoma are based on histologic malignancy-grade, tumor size and tumor depth. These factors are generally dichotomized, size at 5 cm. We believe it is unlikely that tumor depth per se should influence a tumor's metastatic capability. Therefore we hypothesized that the unfavourable prognostic importance of depth could be explained by the close association between size and depth, deep-seated tumors on average being larger than the superficial ones. When tumor size is dichotomized, this effect should be most pronounced in the large size (>5 cm) group in which the size span is larger. METHODS We analyzed the associations between tumor size and depth and the prognostic importance of grade, size and depth in a population-based series of 490 adult patients with soft tissue sarcoma of the extremity or trunk wall with complete, 4.5 years minimum, follow-up. RESULTS Multivariate analysis showed no major prognostic effect of tumor depth when grade and size were taken into account. The mean size of small tumors was the same whether superficial or deep but the mean size of large and deep-seated tumors were one third larger than that of large but superficial tumors. Tumor depth influenced the prognosis in the subset of high-grade and large tumors. In this subset deep-seated tumors had poorer survival rate than superficial tumors, which could be explained by the larger mean size of the deep-seated tumors. CONCLUSION Most of the prognostic value of tumor depth in soft tissue sarcomas of the extremity or trunk wall can be explained by the association between tumor size and depth.

Abstract
AIMS The aims were to review the existing methods of quality assurance in surgical oncology and to determine a relationship between surgery-related factors and the variety in outcomes in the treatment of solid cancers. METHODS The literature was reviewed by searching Medline and Cancerlit databases. RESULTS Wide variations were found in virtually all tumour types. Clear evidence was found that an improvement in the quality of the surgical procedure could have major implications for the prognosis and quality of life of cancer patients. CONCLUSIONS These findings emphasize the need for strict quality control procedures in surgical oncology and might imply a considerable change in cancer treatment strategies, because the routine use of adjuvant therapies could be questioned.

Abstract
BACKGROUND Local recurrence occurs in 10% to 20% of patients with extremity soft tissue sarcomas despite optimal treatment. The association of local recurrence with subsequent survival is controversial and conflicting. There is a need for a staging system to predict outcome in this subset of patients and also to plan optimal treatment, including adjuvant systemic therapy. METHODS Data collected from 110 patients with locally recurrent extremity soft tissue sarcomas were studied. The influence of clinical and pathologic factors on local recurrence, distant metastasis, and disease-specific survival were analyzed by univariate and multivariate techniques. RESULTS Of the 110 patients who presented with local recurrence, 92 had an isolated local recurrence and 18 had prior or concomitant distant metastases. The 5-year disease-specific survival for all patients was 63% and for those with isolated local recurrence, it was 69%. Histologic grade, malignant fibrous histiocytoma histology, pathologic margins, previous local recurrence, and prior radiotherapy were independent prognostic factors for subsequent local recurrence. Tumor size, histologic grade, and time to local recurrence were independent prognostic factors for distant metastasis and disease-specific survival. A prognostic index was calculated by assigning a score of 1 to 3 for each of the three independent prognostic factors for survival and added to give the prognostic index for each patient. As the prognostic index increased from 3 to 9, there was a progressive increase in the hazard ratios and a corresponding deterioration in survival. The patients were then categorized into three prognostic groups based on the hazard ratios for disease specific survival. The differences in the survival curves were highly statistically significant (P < .0001). CONCLUSIONS Tumor size, histologic grade, and time to local recurrence are the primary determinants of distant metastases and survival in locally recurrent extremity soft tissue sarcomas. The impact of local recurrence on survival varies considerably. The nature of the local recurrence, rather than its presence per se, is a more useful guide to prognosis. We propose a simple staging system based on size, grade, and time to recurrence that correlates extremely well with prognosis and may serve as a guide to make therapeutic decisions in patients with locally recurrent extremity soft tissue sarcomas.

Abstract
Radiotherapy and limb-preserving surgery has replaced amputation and compartmental resection for treatment of soft tissue sarcomas. However, the role of radiotherapy in low-grade tumors remains unclear. This study reviews the outcomes of 132 patients who received multimodality treatment for low-grade soft tissue sarcoma. Large primary tumors (> 5 cm) and the absence of radiotherapy correlated with local recurrence. Radiotherapy was most effective in patients operated on with marginal margins. Patients who were treated with wide surgical margins or had small tumors (< or =5 cm) showed no benefit with adjuvant radiotherapy. Size greater than 5 cm and local recurrence correlated with metastasis. Radiotherapy appears to be important in the management of low-grade soft tissue sarcoma. The principles of local treatment for low-grade soft tissue sarcoma should be the same as for high-grade tumors with a combination of surgery and adjuvant radiotherapy. In a subset of patients with small and widely excised tumors, consideration may be given to withholding radiotherapy. Local recurrence and metastasis from low-grade soft tissue sarcoma may occur as long as 1 decade after primary tumor resection. Long-term review of patients with low-grade tumors may be indicated.

Abstract
From the Scandinavian Sarcoma Group Register, information on 1,224 surgically-treated patients with soft tissue sarcoma (STS) of the extremity or trunk wall, diagnosed between 1987 and 1995, was collected. 205 patients, one third of whom were referred to a center with a local recurrence, had a total of 284 local recurrences. This analysis describes the treatment for these local recurrences, complications and risk of further recurrences. 169 patients were surgically treated for their first local recurrence. An intralesional or marginal margin was achieved in 110 of these patients, 59 of whom were also given radiotherapy. 54 of the 169 patients had a second local recurrence. The second local recurrence rate was 0.50 if the first local recurrence had been treated with only surgery with a marginal margin, compared to 0.28 if treated with surgery with a marginal margin and radiotherapy or with a wide margin (p = 0.0008). In extremity STS, the crude amputation rate for local recurrences was 0.22 (31 of 142)-i.e., higher than for primary tumors 0.09 (96 of 1065) (p < 0.0001). A high local recurrence rate after treatment outside of sarcoma centers has earlier been shown. We conclude that the consequences of local recurrence in terms of morbidity and costs justifies referral of STS patients for multidisciplinary evaluation and multimodality treatment.

Abstract
The prognostic importance of surgical margins on local recurrence rates and metastasis-free survival (MFS) was studied in 559 patients with soft tissue sarcoma of the extremities and trunk wall. The patients were all surgically treated, but received no adjuvant treatment. The median follow-up for the survivors was 7.4 (range: 0.1 - 12.5) years. Independent prognostic factors for MFS were analysed by Cox models. The overall 5-year MFS was 0.72 (95% confidence intervals (CI) 0.68 - 0.76). High histopathological malignancy grade (relative risk (RR) 3.0; 95% CI 1.5 - 6.3) and an inadequate surgical margin (RR 2.9; 95% CI 1.8 - 4.6) were independent risk factors for local recurrence. High histopathological malignancy grade and large tumour size (> 7 cm) were the most important risk factors for metastasis. Local recurrence was associated with an increased risk of metastasis (RR 4. 4; 95% CI 2.9-6.8), but an inadequate surgical margin was not a risk factor for metastasis (RR 1.1; 95% CI 0.8-1.7). This study confirms that, as regards metastasis, tumour-related risk factors (malignancy grade and tumour size) are more important risk factors than treatment-related factors. Local recurrence was associated with an increased metastasis rate, whereas inadequate surgical margin was a risk factor for local recurrence but not for metastasis. Hence, the proposed causal association between local recurrence and metastasis is doubtful, and if it exists is a weak association.

Abstract
In the present study, the outcome, patterns of local recurrence and survival, as well as prognostic factors, were evaluated in patients surgically treated for soft tissue sarcomas. Between January 1979 and July 1993, 316 consecutive patients were referred to the Sarcoma Centre in Aarhus with localised malignant soft tissue sarcoma of the extremities or trunk. If possible, the patients were treated with a limb-sparing resection, primarily by use of a wide excision. 50 patients received adjuvant radiotherapy. There were 161 men (51%) and 155 women (49%) median age 56 years (range 1-94 years). 94 patients (30%) had tumours in the trunk, including shoulder and buttock lesions, 163 (52%) in the lower extremity and 59 (19%) in the upper extremity. 52 patients (16%) had grade 1 tumour, 60 (19%) grade 2 and 204 (65%) grades 3A-3B. The 5-year local recurrence rate was 18% and the 5-year survival rate was 75%. Multivariate analysis indicated the following variables as independent unfavourable factors for local recurrence: extracompartmental location, histological high grade, local excision, no adjuvant radiotherapy and intralesional/marginal excision. Independent unfavourable factors for survival were advanced age, extracompartmental location, histological high grade, lower extremity location and large tumour size. If the variable local recurrence was included in the analysis, it was found to have a very strong influence on survival. Based on these variables, a prognostic model was developed.

Abstract
External beam radiation may be given either before or after excision of a primary soft tissue sarcoma. This study was undertaken to determine whether or not the timing of radiotherapy was associated with any difference in either local control, survival, or incidence of complications. The files of 112 patients with a primary, nonmetastatic, extremity soft tissue sarcoma, treated with limb salvage surgery and irradiation were evaluated. Data regarding tumor stage, grade, site, surgical margin, dosage and timing of radiotherapy, treatment complications, disease relapse, and relapse-free survival (RFS) were analyzed. Kaplan-Meier lifetable analysis was used to determine survival estimates. There was no significant difference in the 5-year RFS between patients receiving radiotherapy (RT) preoperatively versus postoperatively; 56 +/- 15% and 67 +/- 12% (P = 0.12, Mantel-Cox), respectively. There was no significant difference in the overall survival between patients receiving RT preoperatively versus postoperatively; 75 +/- 15% and 79 +/- 11% (P = 0.94), respectively. Actuarial local control at 5 years for preoperative versus postoperative RT patients was not statistically different; 83 +/- 12% versus 91 +/- 8% (P = 0.41), respectively. Wound complications were more frequent in preoperative RT patients (31%) compared to postoperative RT patients (8%) (P = 0.0014, chi-square). Preoperative irradiation was not associated with any benefit in terms of relapse-free survival, overall survival or actuarial local control in this series. A higher incidence of major wound complications was found among patients treated with preoperative irradiation. We recommend that patients with a resectable extremity soft tissue sarcoma be treated with postoperative irradiation, reserving preoperative irradiation for those situations in which either the tumor is initially thought to be unresectable or the original tumor boundaries are obscured.
