Assessment of local complications with preoperative versus postoperative radiotherapy in patients with soft tissue sarcoma in extremities: A randomized comparative clinical trial.

[PMID: 38464549 PMCID: PMC10920714 DOI: 10.1016/j.jor.2024.02.042] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/04/2024] [Accepted: 02/24/2024] [Indexed: 03/12/2024] Open
Abstract
Background Radiotherapy is considered a cornerstone as adjuvant or neo adjuvant to surgery in extremity soft tissue sarcoma (ESTS). Wound complications are the most agonizing complication that may have an impact on patient's functional outcome following radiotherapy. The best care for ESTS is by combining extensive surgical excision with safety margin and radiotherapy either preoperative (neoadjuvant) or postoperative. Preoperative radiotherapy allows for lower dose of radiation over smaller fields which is supposed to decrease long-term complications. However, several studies have shown that early complications which include wound dehiscence, infection, seroma and burn may be more frequent with preoperative radiotherapy than with postoperative radiotherapy. Most of these studies were retrospective. This study aims to prospectively assess and compare the early complications associated with radiotherapy in both techniques. Hypothesis Preoperative radiotherapy is not inferior to postoperative radiotherapy regarding early wound complications. Patients and methods Between January 2021 and June 2022, we prospectively studied 22 patients and categorized them into two groups, group A (preoperative radiotherapy) and group B (postoperative radiotherapy). We included patients with extremity soft tissue sarcoma in skeletally mature patients who were randomized into two groups with follow up 9-12 months. Wound complications, local complications, recurrence, time for wound healing and survival rate were recorded and analyzed using SPSS 25. Results 22 patients were included, 10 in group A and 12 in group B, their mean age was 46.4 years with mean follow up 9 months. The major wound complications were higher in group A (preoperative radiotherapy). in comparison with group B (postoperative radiotherapy), however, this was not statistically significant. While other local complications were higher in group B, it was also statistically insignificant. Time for wound healing was higher in group A more than group B and was statistically significant (p value = 0.011). Conclusion No increase in the wound complications rate with preoperative radiotherapy by using low fractionated doses of radiotherapy and increasing interval before surgery to six weeks, although there is increased risk of delayed wound healing time after surgery. The size and site of the tumor may increase the risk of wound complications unrelated to the type of radiotherapy. Level of evidence II: clinical trial.

Identifying risk factors and analyzing reconstructive outcomes in patients with lower-extremity soft-tissue sarcoma. J Plast Reconstr Aesthet Surg 2024; 89:174-185.

Abstract
PURPOSE Reconstructing defects after resecting soft-tissue sarcoma (STS) can be challenging. The aim of this retrospective study was to analyze the reconstructive outcomes and identify the potential risk factors in patients undergoing reconstruction after excision of lower-extremity STS. METHODS Patients with lower-extremity STS were included. This database was compiled of patients from a single, large National Cancer Institute-accredited academic hospital. In total, 302 patients were included between January 2016 to January 2022. Univariate and multivariate analyses were performed to calculate odds ratios (ORs) for developing complications for each patient and surgical characteristic. RESULTS The following factors were independent predictors of any complication: benign pulmonary disease (OR = 4.2; p = 0.02), preoperative radiotherapy (RT; OR = 2.5; p = 0.047), a tumor in the medial thigh (OR = 1.9; p = 0.03), body mass index (BMI) > 30 kg/m2 (OR = 1.05; p = 0.037), and full-thickness skin graft (OR = 5.4; p = 0.01). In the preoperative RT subgroup, reconstructing a defect via undermining and layered closure alone was an independent predictor of dehiscence (OR = 2.1; p = 0.02) and seroma (OR = 3.1; p = 0.02), whereas pedicled flaps (OR = 0.08; p = 0.001) and free flaps (OR = 0.05; p = 0.001) were independent protectors against any complication. CONCLUSION Information derived from this analysis will assist with accurate preoperative patient counseling, which is crucial for informed decision-making and expectation management in lower-extremity STS. BMI and pulmonary function should be optimized to the extent possible to reduce postoperative complications. Patients treated preoperatively with RT should be reconstructed with a pedicled or free flap to optimize recovery.

Cancers (Basel) 2022; 14:cancers14174312.

Abstract
Simple Summary The mainstay of soft-tissue-sarcoma treatment remains ablative surgery with complete tumor resection. In this context, reconstructive plastic surgery has become an important aspect of multidisciplinary sarcoma therapy aiming at limb preservation as an alternative to amputations. In this present study, cross-sectional data collected prospectively at 39 study centers across Germany were analyzed, focusing on both the inhouse availability of plastic surgery and external accessibility to plastic surgery in 621 cases. In summary, unplanned and incomplete primary tumor resections carried out at centers with lower degrees of specialization were associated with a significantly increased need for subsequent flap-based defect coverage. In line with this, a readily available team of plastic surgeons was independently associated with successful defect reconstruction, which in turn was associated with significantly higher chances of limb preservation. We conclude that easily accessible plastic surgery and a high degree of expertise in the field of sarcoma treatment are indispensable for limb preservation following sarcoma resection. Plastic and reconstructive surgery therefore plays a vital role in achieving the best possible outcomes in the interdisciplinary treatment of soft-tissue sarcomas. Abstract Although the involvement of plastic surgery has been deemed important in the treatment of sarcoma patients to avoid oncological compromises and ameliorate patient outcomes, it is not ubiquitously available. The accessibility of defect reconstruction and its therapeutic impact on sarcoma care is the subject of this analysis. Cross-sectional data from 1309 sarcoma patients were collected electronically at 39 German study centers from 2017 to 2019. A total of 621 patients with surgical treatment for non-visceral soft-tissue sarcomas were included. The associated factors were analyzed exploratively using multifactorial logistic regression to identify independent predictors of successful defect reconstruction, as well Chi-squared and Cochran–Mantel–Haenszel tests to evaluate subgroups, including limb-salvage rates in extremity cases. A total of 76 patients received reconstructive surgery, including 52 local/pedicled versus 24 free flaps. Sarcomas with positive margins upon first resection (OR = 2.3, 95%CI = 1.2–4.4) that were excised at centers with lower degrees of specialization (OR = 2.2, 95%CI = 1.2–4.2) were independently associated with the need for post-oncological defect coverage. In this context, the inhouse availability of plastic surgery (OR = 3.0, 95%CI = 1.6–5.5) was the strongest independent predictor for successful flap-based reconstruction, which in turn was associated with significantly higher limb-salvage rates (OR = 1.4, 95%CI = 1.0–2.1) in cases of extremity sarcomas (n = 366, 59%). In conclusion, consistent referral to specialized interdisciplinary sarcoma centers significantly ameliorates patient outcomes by achieving higher rates of complete resections and offering unrestricted access to plastic surgery. The latter in particular proved indispensable for limb salvage through flap-based defect reconstruction after sarcoma resection. In fact, although there remains a scarcity of readily available reconstructive surgery services within the current sarcoma treatment system in Germany, plastic and reconstructive flap transfer was associated with significantly increased limb-salvage rates in our cohort.

One-Stage Soft Tissue Reconstruction Following Sarcoma Excision: A Personalized Multidisciplinary Approach Called "Orthoplasty". J Pers Med 2020; 10:jpm10040278. [PMID: 33327387 PMCID: PMC7768416 DOI: 10.3390/jpm10040278] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2020] [Revised: 12/09/2020] [Accepted: 12/11/2020] [Indexed: 12/11/2022] Open
Abstract
Background and Objectives. Wide surgical resection is a relevant factor for local control in sarcomas. Plastic surgery is mandatory in demanding reconstructions. We analyzed patients treated by a multidisciplinary team to evaluate indications and surgical approaches, complications and therapeutic/functional outcomes. Methods. We analyzed 161 patients (86 males (53%), mean age 56 years) from 2006 to 2017. Patients were treated for their primary tumor (120, 75.5%) or after unplanned excision/recurrence (41, 25.5%). Sites included lower limbs (36.6%), upper limbs (19.2%), head/neck (21.1%), trunk (14.9%) and pelvis (8.1%). Orthoplasty has been considered for flaps (54), skin grafts (42), wide excisions (40) and other procedures (25). Results. At a mean follow-up of 5.3 years (range 2–10.5), patients continuously showed no evidence of disease (NED) in 130 cases (80.7%), were alive with disease (AWD) in 10 cases (6.2%) and were dead with disease (DWD) in 21 cases (13.0%). Overall, 62 patients (38.5%) developed a complication (56 minor (90.3%) and 6 major (9.7%)). Flap loss occurred in 5/48 patients (10.4%). The mean Musculoskeletal Tumor Society (MSTS) and Toronto Extremity Salvage Score (TESS) was 74.8 ± 14 and 79.1 ± 13, respectively. Conclusions. Orthoplasty is a combined approach effective in management of sarcoma patients, maximizing adequate surgical resection, limb salvaging and functional recovery. One-stage reconstructions are technically feasible and are not associated with increased risk of complications.

Abstract
A myopericytoma (MP) is an exceedingly rare perivascular tumor of unknown etiology. Given their potential for mimicry and malignancy, MP tumors pose a unique challenge for surgeons and may be overlooked on differential diagnosis. We present a case report of an otherwise healthy 33-year-old right-hand dominant male who presented to our outpatient clinic with a 2-month history of painless swelling and erythema of the pulp of his left index finger. Subsequent plain film X-ray showed near-complete bony destruction of his distal phalanx. Pathological evaluation of an incisional biopsy showed a benign variant of MP. The lesion was treated by excision with tumor shelling, and there was no evidence of recurrence 81 days postoperatively. A systematic literature review of the management and outcome of all known cases of hand and wrist MP is presented.

Abstract
To examine, in a prospective fashion, the utilization and efficacy of adjuvant radiation therapy (RT) in patients with resected desmoplastic melanoma (DM). Adult patients with resected, margin‐negative, and nonmetastatic DM were eligible for this single‐arm prospective phase II study. Patients were to receive postoperative RT, 30 Gy in five fractions, to the operative bed with 2‐ to 3‐cm margins (depending on the tumor location). Nodal basin RT was not allowed. The primary study endpoint was the 2‐year local recurrence rate (LRR). Secondary endpoints included the incidence of regional and distant metastatic disease, progression‐free survival, overall survival (OS), and treatment‐related toxicity. Twenty patients with a single de novo DM lesion meeting trial eligibility criteria were enrolled and treated. The 2‐year LRR was 10%, with two patients demonstrating a LR within 2 years of completion of protocol therapy. No regional or distant failures occurred. OS at 2 and 5 years was 95 and 77%, respectively. There were no grade 3 or higher acute or late adverse events that were related to the protocol therapy. Adjuvant RT after wide local excision (WLE) for DM is efficacious and well tolerated. It should be considered for DM patients after margin‐negative WLE. Additional study is needed to further refine low‐risk patient populations that can potentially have adjuvant RT omitted as part of the treatment plan.

Abstract
Soft tissue sarcomas arising in the foot and ankle are often misdiagnosed, resulting in excision without adequate preoperative staging or surgical margins. The goal of the present study was to review a case series of soft tissue sarcomas of the foot and ankle with attention directed at unplanned excisions of sarcomas. An unplanned excision means that a patient either underwent an inadequate preoperative workup or the preoperative workup indicated a benign entity, resulting in surgical resection. We retrospectively analyzed the medical records of 10 patients with sarcomas of the foot and ankle treated at our institution. All soft tissue sarcomas were excised with the widest margin possible without any major bone or neurovascular resection to allow for preservation of the foot. All patients were followed up for a minimum of 8 months to assess pain, function, and complications. The patients were followed up for an average of 22.4 (range 8 to 44) months. Of the 10 patients, 6 had undergone preoperative magnetic resonance imaging without contrast and the sarcomas were read as benign or cystic masses. Two patients had undergone preoperative magnetic resonance imaging with contrast, and these scans were also misread. Despite having undergone previous unplanned surgery, none of these sarcomas had recurred after repeat resection with a wider margin at a mean follow-up of 22.4 (range 8 to 44) months. At the last follow-up point, 8 patients were alive without evidence of disease. Minor complications included lymph edema in 1, stress fracture in 1, and wound infection in 1 that resolved. Preoperative MRI with contrast is recommended before resecting any soft tissue masses of the foot and ankle. In the event of an unplanned excision of a soft tissue sarcoma, the patient should be referred to an orthopedic oncologist for definitive surgery to optimize the oncologic and functional results. In the present retrospective analysis, previous intervention did not seem to affect the prognosis, including local recurrence, distant metastasis, disease-free interval, and functional outcomes.

Abstract
Though giant cell tumor is not uncommon in young adults, simultaneous involvement of multiple mid-foot bones is very uncommon and very difficult to treat. For reconstruction of large segmental bony defects following tumour excision, free vascularized bone graft is an excellent surgical option. We report a case with extensive involvement of all the tarsal bones and metatarsal bases in a young adult. After excision his foot was reconstructed with vascularised bone flap. We were able to save his foot after a wide local excision and reconstruction with free fibula graft. Graft united early and showed excellent remodelling because of good vascularity. We feel that this method deserves consideration as a last attempt to salvage functional foot in disease like this.

Abstract
Purpose. Radiation of extremity lesions, a key component of limb-sparing therapy, presents particular challenges, with
significant risks of toxicities. We sought to explore the
efficacy of intraoperative radiation therapy (IORT) in the
treatment of soft tissue sarcomas of the extremities.
Patients. Between 1995 and 2001, 17 patients received
IORT for soft tissue sarcomas of the extremities. Indications for
IORT included recurrent tumors in a previously radiated field or
tumors adjacent to critical structures. Results. Gross
total resections were achieved in all 17 patients. Two patients
experienced locoregional relapses, six patients recurred at
metastatic sites, and one patient died without recurrence.
Thirty-six month estimates for locoregional control, disease free
survival, and overall survival were 86%, 50%, and 78%,
respectively. IORT was extremely well tolerated, with no
toxicities referable to IORT. Conclusions. For patients
with soft tissue sarcomas of the extremities, IORT used as a boost
to EBRT provides excellent local control, with limited acute
toxicities.

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
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.

Abstract
The current recommendation for surgical treatment of tumors of the lower extremity is a limb-sparing resection. Limb-sparing resection coupled with complex reconstructive techniques and complemented by new chemotherapeutic agents and adjuvant radiation therapy has allowed us to achieve survival rates that are comparable to those of amputation with a better functional outcome. Recent advances in microsurgical techniques and the associated technologies and a better understanding of microvascular anatomy has allowed us to customize flaps to the specific needs of the patients and to achieve a lower donor site morbidity. Increased communication between the specialties of the multidisciplinary treatment team has also improved outcomes. The reconstructive component has become an integral part of the multidisciplinary care for patients with lower extremity tumors. It not only allows them to rapidly resume adjuvant therapies but also enables them to more easily resume their activities of daily living.

Abstract
BACKGROUND Limb-preservation surgery has evolved during the last two decades through application of pedicled and free flaps and has obtained oncological results similar to those with amputation for malignant neoplasms of the extremities. However, functional evaluation has not been performed comprehensively after these advanced reconstructive procedures. The aim of this study was to describe the oncological, surgical, and functional outcomes achieved in these patients. METHODS Patients had malignant neoplasms of the extremities and/or shoulder and hip girdle, underwent resective surgery and reconstruction with limb-preservation purposes, and were treated from 1997 to 2002. Survival analysis was performed, and functional evaluation after resection was performed with the Enneking system 1 year after surgery. RESULTS Thirty-two patients were included. The mean overall survival of the cohort was 5.6 years. Functional evaluation mean rating percentages for the upper and lower extremities were 86.5% and 75.2%. Functional outcomes were better for reconstruction with free flaps than with pedicled flaps in the lower extremities (rating percentages, 67% and 79.6%, respectively; P = .018). CONCLUSIONS Limb-preservation surgery is a safe treatment for malignant neoplasms. It can be performed with low morbidity and good oncological outcomes. Functional results in our series were good. Lower limb preservation has superior scores with free flap reconstructions because of their potential to cover extensive defects, and better results were obtained in walking, gait, and weight bearing.

Abstract
PURPOSE To review the role of free tissue transfer in reconstructive surgery following resection of high-grade soft-tissue sarcomas of the lower limb. METHODS Medical records of all consecutive patients with high-grade soft-tissue sarcomas of the lower limbs between August 1997 and September 2003 were reviewed. RESULTS Of 8 patients (6 women and 2 men) aged between 19 and 65 years, 4 had malignant fibrous histiocytoma, one had malignant peripheral nerve sheath tumour, one had synovial sarcoma, one had recurrent liposarcoma, and one had epitheloid sarcoma. The tumour sizes ranged from 132 cm(2) to 483 cm(2). The soft-tissue defects following tumour extirpation ranged from 153 cm(2) to 896 cm(2). The flaps used were 3 free latissimus dorsi flaps, 2 free osteoseptocutaneous fibula flaps (one vascularised fibula flap and one 'double barrel' fibula flap), one free rectus abdominis flap, 2 free mini-transverse rectus abdominis flaps, and one pedicled rectus abdominis flap. Five patients did not have local recurrence and systemic metastases. CONCLUSION Tissue transfer allows early adjuvant therapy facilitating the multimodal approach for the high-grade soft-tissue sarcomas of the lower extremity.

Abstract
BACKGROUND Treatment for soft tissue sarcoma of the upper extremity has evolved to include limb salvage techniques. We reviewed our experience with limb salvage therapy for upper extremity sarcomas with an emphasis on functional outcomes following the reconstructive surgery. METHODS A retrospective analysis was performed of 81 consecutive patients with soft tissue sarcoma of the upper extremity who had limb salvage therapy with reconstruction by a plastic surgeon. Univariate and multivariate regression analyses of relevant outcome variables were performed. Enneking functional scores were obtained from 43 patients. RESULTS The study included 16 microvascular reconstructions and 67 non-microvascular reconstructions for a total of 83 reconstructions in 81 patients. The mean defect size was 129 cm(2) (standard deviation: 106 cm(2)). The mean total functional score was 23.1 (range, 9 to 30). Any reconstruction-related complication and preoperative chemotherapy use were associated with a 7.3 point (P = .03) and 4.7 point (P = .01) decrease in total functional score, respectively. Kaplan-Meier product-limit analysis showed 82% 5-year overall survival and 67% 5-year disease-free survival rates. CONCLUSIONS For soft tissue sarcoma of the upper extremity, limb salvage with good functional outcome is possible with a judicious approach to reconstruction.

Abstract
Limb salvage is a viable alternative to amputation in many cases of advanced sarcoma. The authors examined their experience with microvascular reconstruction of upper extremity defects after sarcoma resection, focusing on oncologic and functional outcomes. A retrospective analysis yielded 17 patients who underwent 18 free flap procedures and met the inclusion criteria. Most patients (71 percent, n = 12) had recurrent sarcoma at presentation to the authors' institution. Malignant fibrous histiocytoma was the most common pathologic subtype (n = 6). High-grade tumors were present in 94 percent of patients (n = 16). The free flap survival rate was 100 percent. The rectus abdominis flap was the most common free flap used (39 percent; n = 7). Local recurrence occurred in nine flaps (50 percent), and five patients ultimately required amputations. Six patients (35 percent) had distant recurrence. The mean Enneking score for limb function was 73 percent of the maximum (21.9 of 30). The 5-year disease-specific survival rate was 61.3 percent. In select patients with advanced upper extremity sarcoma undergoing limb salvage, microvascular flap reconstruction can provide reliable, safe coverage with reasonable preservation of function.

Abstract
Limb salvage procedures for the lower extremity have a 95% success rate and have essentially supplanted primary amputation as the primary treatment for limb-threatening malignancies. En bloc tumor resection involving major neural and vascular structures that once led to amputation are now successfully reconstructed using free-tissue transfer in combination with neoadjuvant and adjuvant chemoradiation therapies and brachytherapy. Planning for reconstruction of complex lower extremity wounds begins at the time of diagnosis and extends to postoperative rehabilitation. Developing a successful reconstructive plan requires a team approach with accurate assessment of the anticipated loss of critical structures, wound location, defect size, and an understanding of the local and distant tissues available for reconstruction. Comprehensive assessment of the anticipated wound combined with an understanding of the distant and local tissues available for reconstruction allows the reconstructive surgeon to select tissues from the entire body that have improved functional and aesthetic outcomes for patients.

Abstract
BACKGROUND AND OBJECTIVES To evaluate the significance of resection margin for soft tissue sarcoma (STS), we determined local recurrence-free interval (LRFI), distant metastases-free interval (DMFI), and overall survival (OS) for primary extremity and truncal STS with clear margins (> or =10 mm), close margins (1-9 mm), and positive margins (0 mm). METHODS Patients were evaluated via review of charts and tumor specimens. RESULTS Among 111 patients, tumors were predominantly high grade (86%), > or =5 cm (76%), and deep (81%). A minority of patients received adjuvant radiation (38%) and/or adjuvant chemotherapy (34%). Margin width was > or =10 mm (48%), 1-9 mm (40%), or 0 mm (12%). Margins > or =10 mm were less common for large (P = 0.009) or deep (P = 0.02) tumors. By multivariate analysis, independent factors for LRFI were tumor size (P = 0.04) and margin width (P = 0.03). Independent factors related to DMFI were tumor grade (P = 0.002), size (P = 0.007), and patient age (P = 0.02). Independent factors relating to OS were tumor grade (P = 0.001), size (P = 0.004), and depth (P = 0.03). CONCLUSIONS Margins > or =10 mm independently predicted longer LRFI and are optimal for extremity STS resection. Adjuvant radiotherapy should be considered for all STS resected with margins <10 mm, and margin width should be considered when reporting and interpreting LR outcomes for these patients.

Abstract
PURPOSE The objective of this study was to define whether survival of patients with extremity soft tissue sarcoma (STS), stratified for known risk factors, has improved over the last 20 years. PATIENTS AND METHODS From January 1982 to December 2001, 1,706 patients with primary and recurrent STS of the extremities were treated at our institution and were prospectively followed. From this cohort, we selected 1,261 patients who underwent complete macroscopic resection and had one of the following histopathologies: fibrosarcoma, liposarcoma, leiomyosarcoma, malignant fibrous histiocytoma, or synovial sarcoma. Median follow-up was 55 months. Patient, tumor, and treatment factors were analyzed as prognostic factors. RESULTS The 5-year disease-specific actuarial survival was 79% (78% for patients treated from 1982 to 1986, 79% for patients treated from 1986 to 1991, 79% for patients treated from 1992 to 1996, and 85% for patients treated from 1997 to 2001; P = not significant). For high-risk patients (high-grade, > 10 cm, deep tumors; n = 247), 5-year disease-specific survival was 51% (50% for patients treated from 1982 to 1986, 45% for patients treated from 1986 to 1991, 52% for patients treated from 1992 to 1996, and 61% for patients treated from 1997 to 2001; P = not significant). Tumor depth, size, grade, microscopic margin status, patient age, presentation status (primary tumor versus local recurrence), location (proximal versus distal), and certain histopathologic subtypes were significant prognostic factors for disease-specific survival on multivariate analysis; however, time period of treatment was not. CONCLUSION Prognosis of patients with extremity STS, stratified for known risk factors, has not improved over the last 20 years, indicating that current therapy has reached the limits of efficacy.

Abstract
BACKGROUND The objective of this study was to define the impact of soft tissue flap reconstruction on multimodality therapy for patients with soft tissue sarcomas of the upper extremity. Treatment standards continue to evolve for these patients, and, with multimodality therapy, most of them are candidates for limb-preserving surgery. Consequently, the role of soft tissue flap reconstruction is expanding. METHODS A review was conducted of 100 consecutive patients with soft tissue sarcomas of the upper extremity who underwent surgery at several institutions between 1992 and 1997. RESULTS Seventy-one patients underwent direct closure of defects after tumor resection, and 29 patients required soft tissue reconstruction with flaps. These groups were similar in most respects, except that 52% of the patients who required soft tissue reconstruction presented with recurrent disease (P = 0.0004), and 79% of them had tumors measuring > 5 cm in greatest dimension (P = 0.0003). The patients who required flap reconstruction had larger skin deficits after undergoing tumor resection (140 cm2) compared with the patients who had wounds that were managed by direct closure (40 cm2; P < 0.00001). Margins around the resected tumors were larger (1.62 cm) when flaps were employed compared with margins when defects were closed directly (0.87 cm; P = 0.0005). However, the number of patients with intralesional, marginal, wide, and radical resections was the same regardless of wound management. Major complications occurred in 14% of patients, but none led to death or amputation. The median follow-up was 31 months, and 66% of patients had no evidence of disease at that time. Rates of local recurrence and survival were similar for patients who underwent flap reconstruction compared with patients who underwent direct closure. CONCLUSIONS Soft tissue flap reconstruction facilitates therapy for patients with soft tissue sarcomas of the upper extremity, so that patients with larger tumors can undergo resection, limiting complications and limb sacrifice.

Abstract
Radiation is used to reduce potential risk of local recurrence from microscopic residual disease after surgical resection. Brachytherapy is a clinically established means of providing radiation for soft-tissue sarcomas that recur after surgical resection alone or surgical resection and radiation. Although the total dose of radiation that is prescribed is approximately the same for patients undergoing external beam radiation or brachytherapy, the radiobiologic characteristics of brachytherapy, based on the inverse-square law, provide higher doses of radiation to the surgical bed. This provides a theoretical advantage for the use of brachytherapy as compared with external beam radiation among patients with recurrence after surgical resection. When soft-tissue sarcomas recur in a previously irradiated area, further external beam radiation generally is not possible; therefore, brachytherapy allows a radiotherapeutic alternative in an attempt to reduce the risk of further local recurrence. Recommendations for patient selection, the total dose of radiation, and the radiation dose-rate are outlined. Standard grading systems for response, symptoms, and severity of complications should be used.

Abstract
Free flaps may safely allow meaningful ambulation, durable limb preservation, and better quality of life in patients undergoing resections of soft-tissue cancers of the foot. To prove this, the records of a series of patients at The University of Texas M. D. Anderson Cancer Center (n = 67) who underwent limb salvage following tumor-related resection (n = 71 procedures) from 1989 to 1999 were retrospectively reviewed. Eighteen patients who were not candidates for local flaps or skin grafts received a total of 20 free flaps to preserve their limbs. Most defects (mean size, 78 cm2; range, 20 to 150 cm2) were on a weight-bearing surface of the foot (nine on a weight-bearing heel, three on a plantar foot); the remainder were on a non-weight-bearing surface (six on dorsum, two on a non-weight-bearing heel). Melanoma was diagnosed in nine cases (50 percent); soft-tissue sarcoma, in seven (39 percent); and squamous cell carcinoma, in two (11 percent). Fasciocutaneous and skin-grafted muscle flaps were used on both weight-bearing and non-weight-bearing surfaces. Free-tissue transfer was successful in 17 of 20 cases (85 percent); the three flap losses occurred in two patients. Minor complications (i.e., small hematoma, partial skin graft loss, and delayed wound healing) occurred in five patients. In all cases of successful free-tissue transfer, patients began partial weight bearing at a mean of 7.4 weeks (range, 2 to 12 weeks), and all ultimately achieved full weight bearing. Sixty-seven percent still required special footwear. In one patient, an ulceration on the weight-bearing portion of the flap resolved after a footwear adjustment. Only one patient was lost to follow-up (mean, 23 months). In the 17 remaining patients, limb salvage succeeded in 15 (88 percent). Of these, nine (60 percent) were alive without evidence of disease, three (20 percent) were alive with disease, and three (20 percent) had died of disease. Local recurrence developed in two patients but was successfully treated by excision and closure. No late amputations were required for local control. Thus, it seems that free flaps help facilitate limb salvage and that they may preserve meaningful limb function in patients who undergo resection of soft-tissue malignancies of the foot.

Abstract
BACKGROUND p53 mutations occur in almost half of all soft tissue sarcomas (STS) and may contribute to multidrug resistance (MDR) in patients with STS. Doxorubicin (Dox) is one of the most active single agents in STS but is less effective in STS with p53 mutations. The effect of reintroducing wild type (wt) p53 into STS cells harboring p53 mutations on the cytotoxicity of DOX in vitro and in vivo was studied. METHODS The following cell lines were used in this study: SKLMS-1 STS cells, which do not express wt p53; two wt p53 stable transfectant cells derived from SKLMS-1 cells; and SKLMS-1 transfectant cells from a p53 temperature-sensitive mutant that expresses wt p53 at 32 degrees C and mutant p53 at 38 degrees C. The cytotoxicity of Dox was examined by [3-(4,5-dimethylthiazzol-2-yl)-2,5-diphenltetrazolium] (MTT) and clonogenetic assay, and the effect of reintroducing wt p53 on tumor suppression by Dox was evaluated with a tumorigenicity assay. DNA fragmentation was used to detect apoptosis. MDR-1 P-glycoprotein (P-gp) expression was detected by Western blot and immunohistochemical analyses of protein levels and by Northern blot analysis of mRNA levels, respectively. The intracellular accumulation of Dox was detected by flow cytometric analysis. RESULTS The 50% inhibitory concentration (IC(50)) of Dox for the SKLMS-1 wt p53 transfectants decreased 16-fold compared with SKLMS-1 parental cells expressing mutant p53. Colony formation of SKLMS-1 cells after Dox treatment also was inhibited by wt p53 reintroduction. The tumorigenicity of SKLMS-1 cells was inhibited by wt p53 reintroduction alone or by Dox treatment alone and was inhibited further when p53 introduction was combined with Dox treatment in severe combined immunodeficient mice. Although no difference in DNA fragmentation, Bax expression, or Bcl-2 expression was detected among wt p53 transfectants and parental SKLMS-1 cells after Dox treatment, MDR-1 P-gp expression was decreased in wt p53 transfectants compared with parental SKLMS-1 cells. Furthermore, higher intracellular accumulations of Dox were found in wt p53 transfectants than that in SKLMS-1 cells. CONCLUSIONS Reintroduction of wt p53 into STS cells harboring p53 mutations can enhance their chemosensitivity to Dox through the inhibition of MDR-1 P-gp expression. Thus, the combination of p53 gene therapy and chemotherapy may increase the therapeutic efficacy in the treatment of patients with STS.

Abstract
PURPOSE To determine the clinical and functional outcomes of children undergoing limb-sparing therapy for extremity sarcomas. METHODS AND MATERIALS We retrospectively reviewed 30 patients, age < or = 21 years, who were treated between l979 and l998 with external beam radiotherapy as a component of limb-sparing therapy for primary sarcomas of the extremity at UCSF. Included were patients for whom complete follow-up and functional outcome assessments were available. We assessed the patterns of failure, overall survival, disease-free survival, local control, and limb function. RESULTS At a median follow-up of 3 years, 12 of the 30 patients recurred: 3 locally, 8 distantly, and 1 with synchronous local and distant disease as site of first progression. Eighteen patients were alive with no evidence of disease. The median overall survival was 10 years, with a median disease-free survival of 8 years. Functional outcome assessment revealed 15 patients retained excellent, 12 good, 1 fair, and 2 poor limb function. CONCLUSION In pediatric patients receiving limb-sparing therapy, 90% maintained excellent or good limb function without compromising survival, demonstrating the validity of limb preservation in children with extremity sarcomas.

Abstract
The size and complexity of wounds following soft-tissue sarcoma resection have increased over the years. Many advances have been made in reconstructive surgery during the past 30 years. These advances have occurred because of refined knowledge of muscle, skin, and fascial blood flow and through the development of free tissue transfer techniques. In this review, current methods of reconstruction following sarcoma resection are discussed, and advances are highlighted.

Abstract
Stewart-Treves syndrome (STS) is the rare occurrence of angiosarcoma in a setting of postmastectomy upper extremity lymphedema. A collective comparison of outcomes following various initial treatment options in STS has not previously been reported. We reviewed 160 cases of STS reported in the literature since 1966. We analyzed the relationship between initial treatment and survival in all 92 of these patients for whom detailed treatment and outcome data had been reported. There was no significant difference in survival comparing those initially treated with wide excision (n = 16) and those treated with amputation (n = 45) (P = 0.40). Even in the setting of initial surgical treatment, overall long-term survival was poor (<40%). There have been even fewer long-term survivors among those treated initially with regional chemotherapy (n = 7) or radiation therapy (n = 24). An update on STS and a discussion of recent advances in the understanding of its molecular pathogenesis that may result in future treatment improvements are presented.

Abstract
PURPOSE It has been suggested that patients with small (< 5 cm), high-grade extremity soft tissue sarcomas (STS) have an excellent overall prognosis and, consequently, may not require adjuvant therapies. PATIENTS AND METHODS A comprehensive review of all patients with extremity STS treated at a tertiary care cancer hospital over a 9-year period (January 1984 to December 1992) was performed. Prognostic factors, treatment data, and long-term outcome were evaluated in the subset of 111 patients with American Joint Committee on Cancer stage IIB (G3/4, T1a/b) disease. RESULTS The median tumor size was 3.0 cm (range, 0.6 to 4.9 cm), and 55 tumors (50%) were deep in location. All patients underwent surgical resection; 68 (61%) received pre- or postoperative radiotherapy, and 32 (29%) received doxorubicin-based chemotherapy. The median follow-up was 76 months. Forty patients (36%) experienced 59 recurrences. First recurrences occurred at local, regional, and distant sites in 21, five, and 14 patients, respectively. The 5-year actuarial local recurrence-free, distant recurrence-free, disease-free, and overall survival rates were 82%, 83%, 68%, and 83%, respectively. The presence of a microscopically positive surgical margin was an independent adverse prognostic factor for both local recurrence (relative risk [RR] = 3.75; 95% confidence interval [CI], 1.25 to 11.25; P =.02) and disease-free survival (RR = 2.57; 95% CI, 1.33 to 4.98; P =.005). CONCLUSION Event-free outcome for this subset of patients with high-grade STS does not seem as favorable as previously reported by other investigators. Patients who undergo maximal surgical resection with microscopically positive margins represent a subset of T1 STS patients who warrant consideration for adjuvant therapies.

Abstract
Plastic surgical techniques continue to evolve to deal with problem wounds following soft tissue sarcoma resection. Important advances in how tissue is transferred have allowed most wounds to be closed following extirpation; the emphasis is now placed on refining these transfers while minimizing donor site injury. Reconstructive microsurgery has emerged as a frequently preferred way to resurface wounds after sarcoma resection, particularly in patients who have received radiotherapy or previous surgery. Free flaps provide well-vascularized tissue to fill dead space, cover exposed vital structures, and provide structural support and contour. These procedures demonstrate a high success rate of over 90% and often can ensure a healed wound in a single-stage operation. Creative use of the versatile rectus abdominis or latissimus dorsi myocutaneous flaps can reconstruct the majority of breast, extremity, and head and neck soft tissue defects. Endoscopic harvest of muscle flaps has minimized donor morbidity and scarring. The use of "fillet flaps" is an important concept that spares a patient donor site. Composite free flaps, including bone, are routinely used to rebuild the mandible or other bony structures. The future holds great promise for sarcoma reconstruction because tissue engineering is rapidly closing in on techniques that can duplicate tissues in the laboratory for ultimate use in reconstruction, thus sparing the donor site from disease.

Abstract
Current chemoradiation treatment strategies have largely evolved out of the experience reported by Eilber and colleagues from the University of California, Los Angeles (UCLA). The favorable local control rates they reported using intra-arterial doxorubicin-based concurrent chemoradiation have been confirmed by several other groups with some groups reporting local control rates in excess of 95% with this approach. This has led to further studies designed to evaluate: 1) the optimal route for chemotherapy administration--intra-arterial vs. intravenous, 2) the possible advantage of protracted infusion of the radiosensitizer vs. brief infusion, 3) the efficacy of other intravenous and oral radiation sensitizers, and 4) the efficacy of sequential chemoradiation using multi-agent chemotherapy alternating with radiotherapy. The results of these investigations are reviewed as the basis for ongoing research evaluating chemoradiation strategies for the treatment of patients with localized sarcoma.

Abstract
BACKGROUND/PURPOSE Because the management of pediatric nonrhabdomyosarcoma soft tissue sarcomas (NRSTS) is determined by extrapolation from adult studies, the effect of margin of tumor resection and postoperative radiation therapy (RT) on local tumor recurrence in children has not been assessed. METHODS Records of NRSTS patients from a single institution were reviewed with regard to demographic data, TNM staging, grade, histological type and site of primary tumor, RT, and local tumor recurrence. The margin of resection was determined by pathological review and did not necessarily reflect operative margins. RESULTS Eighty-eight clinical group I patients were treated over a 30-year period. The most common histological tumor subtypes were synovial cell sarcoma (n = 26), malignant fibrous histiocytoma (n = 17), and fibrosarcoma (n = 7). The mean age was 9.4 years (range, 0 to 29 years). Thirty-four patients had high-grade tumors. Two of ten patients with low-grade tumors and margins less than 1 cm, including one of five who had received RT, had a local recurrence. Patients with low-grade tumors and margins greater than 1 cm (n = 44) had a lower recurrence rate (2 of 44, 4.5%). None of these patients had received RT. Fourteen patients with high-grade tumors had margins less than 1 cm. Seven of these had RT and had no recurrence. Three of the seven patients who received no RT had a recurrence (42.9%). None of the 20 patients with high-grade tumors and margins greater than 1 cm received RT; four of these patients had recurrences (20%). Seven of the 12 irradiated patients (58.3%) had serious radiation-associated complications (wound dehiscence, fracture, growth retardation, and joint dysfunction). CONCLUSIONS Grade alone does not determine the rate of local recurrence. In both low- and high-grade tumors, a pathological margin of resection greater than 1 cm reduced local recurrence. Radiotherapy provided no advantage in low grade tumors but did decrease local recurrence rates in high-grade tumors with less than 1 cm pathological margins.
