Functional outcomes of reconstructive flap surgery for soft tissue sarcoma: Long-term outcomes of functional restoration using innervated muscle transplantation. J Plast Reconstr Aesthet Surg 2024; 91:312-321. [PMID: 38442511 DOI: 10.1016/j.bjps.2024.02.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2023] [Revised: 12/11/2023] [Accepted: 02/04/2024] [Indexed: 03/07/2024]
Abstract
Functional outcomes associated with prognostic factors and innervated muscle transplantation after wide soft tissue sarcoma resection remain unclear. We retrospectively examined the functional outcomes of reconstructive flap surgery for soft tissue sarcoma. Twenty patients underwent innervated muscle transplantation with pedicled or free flaps for functional reconstruction of resected muscles. Thirteen latissimus dorsi muscles and one vastus lateralis muscle combined with an anterolateral thigh flap were transferred as free flaps using the epi-perineural suture technique. Six latissimus dorsi muscles were transferred as pedicled flaps with neural continuity. Postoperative functional outcomes were assessed using the Musculoskeletal Tumor Society (MSTS) scores for the upper and lower extremities of 22 and 24 patients, respectively. The mean MSTS score for all patients was 82.3 at 12 months postoperatively. The mean scores for patients who underwent reconstruction with pedicled and free flaps were 89.2 and 77.1, respectively. The MSTS scores for the lower extremity, tumor size ≥5 cm, and free flap reconstruction were significantly lower than those for the upper extremity, tumor size <5 cm, and pedicled flap reconstruction (P = 0.02, 0.37, and 0.008, respectively). The postoperative MSTS score for innervated muscle transplantation was 76.7 at 12 months and was significantly higher (83.7) at 24 months (P = 0.003). Functional outcomes were significantly associated with tumor location, tumor size, and reconstructive flap type based on the MSTS scores. Innervated muscle transplantation improved functional outcomes at 24 months postoperatively via sufficient recovery of the innervated muscle, not the compensatory recovery of the remaining muscle.

Clin Transl Radiat Oncol 2021; 31:42-49. [PMID: 34622039 PMCID: PMC8479243 DOI: 10.1016/j.ctro.2021.08.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 08/10/2021] [Accepted: 08/24/2021] [Indexed: 11/13/2022] Open
Abstract
First to evaluate PROMIS for patients undergoing radiotherapy and surgery for sarcoma. Patients exhibited meaningful change in PROMIS scores throughout the treatment. Analyses show PROMIS scores were similar between pre- and post-operative radiotherapy. Wound complications were associated with increases in anxiety and decreases in function. These data should be considered when selecting ideal therapy.
Introduction Few recent studies have examined patient reported outcomes (PROs) during pre- or post-operative radiation therapy (RT) for soft tissue sarcoma (STS), and none have used PROMIS. This study aims to examine PROMIS scores across peri-operative time points for patients receiving pre- or post-operative RT. Methods Anxiety, depression, pain interference, and physical function PROMIS domains were collected at the pre-operative (1), immediate post-operative (2), and post-treatment completion (3) timepoints for patients undergoing surgery and either pre-operative or post-operative RT. Median scores were compared between groups using the Kruskal-Wallis test. The reliable change index was used to determine minimum important change in PROMIS scores and to compare scores between timepoints. Results 95 patients were included (19 pre-operative, 76 post-operative). Both groups had significant decreases in function during treatment. Patients with wound complications were more likely to have significant increases in anxiety (36.4% vs. 8.3%; p = 0.020) and decreases in physical function (57.1% vs. 16.2%; p = 0.011) independent of RT timing. Conclusions This study demonstrates minimum significant change thresholds to detect PROMIS changes in STS patients undergoing pre- and post-operative radiotherapy. As expected, more patients with pre-operative RT than post-operative RT had wound complications (p = 0.06), but patients with complications in both groups had worse anxiety and function at the completion of treatment compared with those that did not. The association of wound complications with worse anxiety and physical function at completion of treatment should be considered when making individualized treatment recommendations regarding the timing of RT.

Abstract
Background There is no clear evidence on whether radiotherapy (RT) improves treatment result in patients with retroperitoneal sarcomas (RPS). Methods A systematic literature search was performed using PubMed, Scopus and CENTRAL databases. Data were retrieved from published comparatives studies in patients with RPS undergoing surgery alone or RT plus surgery. The primary endpoints were the 5-year OS and the median OS. The secondary endpoints were the recurrence-free survival (RFS) and the R0-resection rate. Continuous outcomes were calculated by means of weighted mean difference (WMD). Results Ten out of 374 articles were analyzed. The median OS and the 5-year survival were significantly increased in patients treated with RT and surgery, compared to patients treated with surgery alone (p < 0.00001, p < 0.001). Median RFS was significantly increased in patients treated with either preoperative (p < 0.001) or postoperative (p = 0.001) RT compared to patients that underwent surgery alone. Finally, median R0-resection rate was similar between the two groups (p = 0.56). Conclusion RT along with radical surgery could be the standard of care in at least a subgroup of patients with RPS.

Abstract
BACKGROUND AND OBJECTIVES Standard treatment for extremity sarcoma is limb-sparing surgery often with radiation, but complications occur frequently. We sought to determine factors predictive of wound complications after thigh sarcoma resection and reconstruction while analyzing trends over time. METHODS We reviewed all thigh defects requiring plastic surgeon reconstruction following sarcoma resection at our institution from 1997 to 2014. Patient demographics, comorbidities, operative characteristics, multi-modality therapies, and complications were analyzed. Wound complications were: infection, dehiscence, seroma, hematoma, or partial/total flap loss. RESULTS There were 159 thigh reconstructions followed for 30 months on average. Eighty-seven percent of patients underwent radiation and 42% had chemotherapy. Almost half (49.1%) had a complication. The most common wound complication was surgical site infection (23.3%) followed by dehiscence (19.5%), and seroma (10.7%). Less common were partial (2.5%) or total flap loss (0.6%). Reoperation was required in 21 patients (13.2%). Tobacco use, older patient age, cardiac disease, and higher body mass index were independently associated with wound complications. Complications trended towards decreasing over time, but this was not statistically significant. CONCLUSIONS Tobacco use, cardiac disease, and higher body mass index, but not the timing of reconstruction, appear to increase the risk of wound complications after thigh soft tissue sarcomas resection and plastic surgery reconstruction.

Abstract
AIMS The purpose of the study was to investigate the time dependent dynamics of wound complications and local control after preoperative radiotherapy (RT) in Extremity Soft Tissue Sarcomas (ESTS). PATIENTS & METHODS In this retrospective cohort study, all patients treated for an extremity sarcoma with pre-operative radiotherapy followed by surgery were identified from a prospectively maintained database. A wound complication (WC) was defined as any local complication of the surgical area requiring intervention, hospital readmission or significant extension of the initial admission period. RESULTS A total of 191 preoperatively irradiated ESTS patients were included in this study. WC was seen in 31% of the patients (n = 60). WC started after a median time of 25 days from surgery, with a median duration of 76 days. Adiposity, smoking and a lower extremity or superficial tumor localization were significantly correlated with an increased WC rate. Risk factors for a duration of WC ≥ 120 days are early development of WC (≤21 days after surgery) and smoking. Local control rates after 1, 3 and 5 years were 99%, 93% and 93%, respectively. CONCLUSION Approximately one-third of patients selected for preoperative RT develops a WC, typically in smoking, adipose patients with superficial tumor localizations in the lower extremity. Based upon the well-established superior long-term functional outcome, maintained excellent local control rates and the temporary nature of the WC issue, preoperative RT remains our preferred treatment. Although, in patients at high risk of WC, post-operative RT might be considered.

Abstract
Background The most common site of sarcoma metastasis is the lung. Surgical resection of pulmonary metastases and chemotherapy are treatment options that have been employed, but many patients are poor candidates for these treatments for multiple host or tumor-related reasons. In this group of patients, radiation might provide a less morbid treatment alternative. We sought to evaluate the efficacy of radiotherapy in the treatment of metastatic sarcoma to the lung. Methods Stereotactic body radiotherapy (SBRT) was used to treat 117 pulmonary metastases in 44 patients. Patients were followed with serial computed tomography imaging of the chest. The primary endpoint was failure of control of a pulmonary lesion as measured by continued growth. Radiation-associated complications were recorded. Results The majority of patients (84%) received a total dose of 50 Gy per metastatic nodule utilizing an image-guided SBRT technique. The median interval follow-up was 14.2 months (range 1.6–98.6 months). Overall survival was 82% at two years and 50% at five years. Of 117 metastatic nodules treated, six nodules showed failure of treatment (95% control rate). Twenty patients (27%) developed new metastatic lesions and underwent further SBRT. The side effects of SBRT included transient radiation pneumonitis (n=6), cough (n=2), rib fracture (n=1), chronic pain (n=1), dermatitis (n=1), and dyspnea (n=1). Conclusion Stereotactic body radiotherapy is an effective and safe treatment for the ablation of pulmonary metastasis from sarcoma. Further work is needed to evaluate the optimal role of SBRT relative to surgery or chemotherapy for treatment of metastatic sarcoma.

Abstract
Background Surgery in combination with radiotherapy (RT) has become the standard of care for most soft tissue sarcomas. The choice between pre- and postoperative RT is controversial. Preoperative RT is associated with a 32–35% rate of major wound complications (MWC) and 16–25% rate of reoperation. The role of vascularized soft tissue “flaps” in reducing complications is unclear. We report the outcomes of patients treated with preoperative RT, resection, and flap reconstruction. Patients and methods 122 treatment episodes involving 117 patients were retrospectively reviewed. All patients were treated with 50.4 Gy of external beam radiation. Surgery was performed at 4–8 weeks after completion of RT by the same combination of orthopedic oncology and plastic reconstructive surgeon. Defects were reconstructed with 64 free and 59 pedicled/local flaps. Results 30 (25%) patients experienced a MWC and 17 (14%) required further surgery. 20% of complications were exclusively related to the donor site. There was complete or partial loss of three flaps. There was no difference in the rate of MWC or reoperation for complications with respect to age, sex, tumor site, previous unplanned excision, tumor grade, depth, and type of flap. Tumor size ≥8 cm was associated with a higher rate of reoperation (11/44 vs 6/78; P = 0.008) but the rate of MWC was not significant (16/44 vs 14/78; P = 0.066). Conclusion The use of soft tissue flaps is associated with a low rate of MWC and reoperation. Our results suggest that a high rate of flap usage may be required to observe a reduction in complication rates.

Abstract
Wound complications represent a major source of morbidity in patients undergoing radiation therapy (RT) and surgical resection of soft tissue sarcomas (STS). We investigated whether factors related to RT, surgery, patient comorbidities, and tumor histopathology predict the development of wound complications. An observational study of patients who underwent STS resection and RT was performed. The primary outcome was the occurrence of any wound complication up to four months postoperatively. Significant predictors of wound complications were identified using multivariable logistic regression. Sixty-five patients representing 67 cases of STS were identified. Median age was 59 years (range 22-90) and 34 (52%) patients were female. The rates of major wound complications and any wound complications were 21% and 33%, respectively. After adjusting for radiation timing, diabetes (OR 9.6; 95% CI 1.4-64.8; P = 0.02), grade ≥2 radiation dermatitis (OR 4.8; 95% CI 1.2-19.2; P = 0.03), and the use of 3D conformal RT (OR 4.6; 95% CI 1.1-20.0; P = 0.04) were associated with an increased risk of any wound complication on multivariable analysis. These data suggest that radiation dermatitis and radiation modality are predictors of wound complications in patients with STS.

Abstract
Percutaneous biopsies allow for precise diagnosis in soft tissue sarcomas and have a low rate of complications. However, it is unknown whether biopsies performed in a community setting lead to higher rates of wound complications at the time of resection. The goal of this study was to determine whether percutaneous biopsies performed at a sarcoma center have lower rates of wound complications compared with those performed in the community setting. A total of 125 patients with soft tissue sarcomas were treated with neoadjuvant radiation followed by limb-sparing resection. Of these, 92 underwent percutaneous biopsy. Patient, demographic, and treatment variables and postoperative wound complications were reviewed. Predictors of wound complications were evaluated with Fisher's exact test for univariate analysis and with logistic regression for multivariate analysis. The wound complication rate was 27% for open or percutaneous biopsies. When only percutaneous biopsies were assessed, the wound complication rate was 25%. The wound complication rate for percutaneous biopsies was 18% when the biopsy was performed at the authors' sarcoma center and 46% when the biopsy was performed in the community setting (P=.01). The Common Terminology Criteria for Adverse Events grade 4 wound complication rate was 73% in patients who underwent percutaneous biopsy at a community hospital vs 14% in those who underwent percutaneous biopsy at the authors' sarcoma center (P=.005). Multivariate analysis showed that lower-extremity soft tissue sarcomas (P=.03) and biopsies performed in the community setting (P=.01) had an increased rate of postoperative wound complications. Percutaneous biopsies performed at community hospitals had an increased incidence of grade 4 postoperative wound toxicity compared with biopsies done at tertiary centers. These wound results confirmed previous recommendations that biopsy of soft tissue sarcomas should be performed at an experienced sarcoma center.

Abstract
Background There is still no consensus regarding the management of patients with massive liposarcomas located in the extremities. Several discrepancies related to the aggressiveness of the surgery and the application of concomitant radiotherapy and chemotherapy treatments remain controversial. The purpose of this study was to analyse the clinicopathological characteristics, prognostic factors and outcomes of a series of patients with massive liposarcomas of the extremities who were treated at a referral hospital specializing in musculoskeletal oncology. Methods This was an observational, descriptive and retrospective case series covering 10 years of clinical practice. The records of 26 adults, 14 men and 12 women, with localized massive liposarcomas in the extremities were studied. The average age was 53 years. The patients were treated from January 2003 until January 2012. Wide surgical resections with limb-sparing surgeries were performed for most patients (96.2 %). Results The average tumour size was 15.1 ± 6.8 cm in the greatest dimension. Regarding the histological subtypes, there were 11 well-differentiated or atypical lipomatous tumours (42.3 %), 10 myxoid (38.5 %) and 5 (19.2 %) round cell and pleomorphic liposarcomas. Regarding the malignancy grades, 19 cases (73 %) were classified as low grade. Among these low-grade tumours predominated the well-differentiated subtype (57.9 %). Within high-grade tumours, the round cell and pleomorphic subtype was most frequent (57.1 %; p = 0.011). Radiotherapy was additionally applied to 12 patients (46.2 %) and adjuvant chemotherapy to 5 (19.3 %). Tumour recurrence was observed in only 2 cases (7.7 %). Only 1 of these cases developed lung metastatic dissemination. Conclusions Across the entire series, these massive tumours did not compromise the survival of the patients. The histologic subtype and the malignancy degree were closely related. Proper and early diagnosis and therapeutic management of these patients via the application of wide-margin surgical excision are essential to ensure long-term survival.

Abstract
Liposarcoma is an uncommon connective tissue tumor arising from lipoblast cells. The lesion is located in body soft parts and rarely arises from the bones. The tumors are variable in presentation ranging from benign well-differentiated tumors to myxoid and round cell-dedifferentiated and pleomorphic forms which can present with metastases. The lesions are most often treated by surgical resection. Chemotherapy and radiation may be added to the treatment of the more malignant variants with some success.

Abstract
BACKGROUND Soft tissue sarcomas are a rare and heterogenous group of malignancies that are derived from the mesenchymal cell lines. In the last few decades, the management of these lesions has been improved by the introduction of dedicated Multi Disciplinary Teams (MDTs) where most bone and soft tissue tumours are now treated.(1) Following the recent changes to management outlined by the NICE/IOGs, we believe it is pertinent to review the current thinking on soft tissue tumour management.(2) We also discuss the principles of diagnosis and treatment and the role of adjuvant therapy. METHODS This is a retrospective review. In the preparation of this paper, we have referred to recent NICE guidelines in this field and have performed a Medline search of the existing literature. RESULTS The key to the success is early and appropriate patient referral. Whilst the responsibility for performing surgery has shifted away from the generalist and towards the super specialist, improvements in survivability can be achieved by promoting basic knowledge within the medical profession as a whole. CONCLUSIONS Both excision and biopsy of a soft tissue sarcoma by a non-specialist surgeon have been shown to increase the risk of tumour recurrence and all invasive procedures should now be performed within the MDT setting.

Abstract
PURPOSE Radiation has been shown to improve local control after resection of soft tissue sarcomas. However, it may also result in major complications in the hand, given the compact nature of functional tissues and limited tissue volumes in the hand. The purpose of this investigation was to describe the hand-specific complications of radiation therapy for patients with soft tissue sarcoma of the hand (STSH). METHODS We performed a retrospective chart review of 55 consecutive patients with STSH treated by a single surgeon between 1993 and 2006. We identified 26 patients who were treated with external beam radiation, brachytherapy, or both, either preoperatively or postoperatively, and reviewed their clinical course. RESULTS After a median follow-up of 7 years, 29 treatment-related complications occurred in 19 patients who had received radiation, whereas 3 of the 29 patients treated with surgery alone developed complications. All patients who received brachytherapy and 14 of the 21 treated with external beam radiation alone developed complications. There were 5 early minor, 2 early major, 3 late minor, and 19 late major complications. CONCLUSIONS Patients with STSH who underwent radiation therapy had a high rate of complications. The complication rate in our series was higher in patients who had brachytherapy catheters placed adjacent to finger joints. A better understanding of predictors of complications will help to determine the optimal timing and type of radiation therapy to treat patients with STSH.

Abstract
Soft-tissue sarcoma (STS) is a histopathologically diverse group of tumors accounting for approximately 10,000 new malignancies in the US each year. The proximal lower extremity is the most common site for STS, accounting for approximately one-third of all cases. Coordinated multimodality management in the form of surgery and radiation is often critical to local control, limb preservation, and functional outcome. Based on a review of currently available Medline literature and professional experience, this paper provides an overview of the treatment of STS of the lower extremity with a particular focus on the modern role of radiotherapy.

Abstract
Soft-tissue sarcomas are rare malignancies of mesodermal origin. Common sites of involvement include the extremities, trunk, retroperitoneum, and the head and neck. Soft-tissue sarcomas of the extremities and pelvis are the most relevant to the orthopaedic surgeon. The patient with extremity soft-tissue sarcoma typically presents with a painless, enlarging mass. Advanced imaging techniques and biopsy, which are best done at tertiary referral centers, usually confirm the diagnosis. Factors such as sarcoma size, location, grade, histologic subtype, and stage, as well as patient age and comorbidities, determine the specific approach to management and patient outcome. Limb-sparing surgical resection is the mainstay of treatment. Radiation is used for unresectable tumors and as a neoadjuvant or an adjuvant to resection. The use of chemotherapy is controversial, and no standardized protocol has been established.

Abstract
OBJECTIVE Malignant neoplasms of the vagina are rare gynecologic tumors. Primary vaginal sarcomas are even more unusual lesions, representing fewer than 2% of malignant vaginal lesions. CASE We present a case of a primary vaginal spindle cell sarcoma, treated with neoadjuvant radiation followed by total pelvic exenteration. The patient remains without evidence of disease 2 years after surgery. CONCLUSIONS The mainstay of treatment of vaginal sarcomas is surgical. Neoadjuvant radiation treatment may decrease surgical morbidity and lead to long-term cure.

Abstract
Synovial sarcoma is the fourth most common type of soft-tissue sarcoma, accounting for 2.5%-10.5% of all primary soft-tissue malignancies worldwide. Synovial sarcoma most often affects the extremities (80%-95% of cases), particularly the knee in the popliteal fossa, of adolescents and young adults (15-40 years of age). Despite its name, the lesion does not commonly arise in an intraarticular location but usually occurs near joints. Histologic subtypes include monophasic, biphasic, and poorly differentiated; the cytogenetic aberration of the t(X;18) translocation is highly specific for synovial sarcoma. Although radiographic features of these tumors are not pathognomonic, findings of a soft-tissue mass, particularly if calcified (30%), near but not in a joint of a young patient, are very suggestive of the diagnosis. Cross-sectional imaging features are vital for staging tumor extent and planning surgical resection; they also frequently reveal suggestive appearances of multilobulation and marked heterogeneity (creating the "triple sign") with hemorrhage, fluid levels, and septa (creating the "bowl of grapes" sign). Two features associated with synovial sarcoma that may lead to an initial mistaken diagnosis of a benign indolent process are slow growth (average time to diagnosis, 2-4 years) and small size (< 5 cm at initial presentation); in addition, these lesions may demonstrate well-defined margins and homogeneous appearance on cross-sectional images. Synovial sarcoma is an intermediate- to high-grade lesion, and, despite initial aggressive wide surgical resection, local recurrence and metastatic disease are common and prognosis is guarded. Understanding and recognizing the spectrum of appearances of synovial sarcoma, which reflect the underlying pathologic characteristics, improve radiologic assessment and are important for optimal patient management.

Abstract
BACKGROUND Major wound complications (MWCs) are frequent after preoperative radiotherapy (RT) for extremity soft-tissue sarcoma (STS). We examined the rate of MWCs at a single institution with readily available reconstructive surgery. METHODS The medical records of consecutively treated extremity STS patients treated with preoperative external-beam RT and surgical resection from June 1996 through February 2003 were reviewed. Patients underwent RT (median 50 Gy), followed by resection 4-8 weeks later. Patients believed to be at higher risk for MWC underwent wound closure by the reconstructive surgery service (RSS). MWCs included secondary operation, invasive procedure, hospital readmission, or persistent deep packing or dressing changes. RESULTS A total of 173 patients underwent preoperative RT. Median age was 54 years; 51% were female; 80% had lower extremity STS. Wound closure was performed by the primary surgeon in 91 cases (53%). The RSS performed wound closure in the remaining 82 patients (47%). One or more MWCs occurred in 55 patients (32%). Wound complications were more likely in patients with lower extremity (49/138, 36%) than upper extremity (6/35, 17%) STS (P = 0.03). Among patients with lower-risk wounds closed by the primary surgical team, 29 (32%) experienced MWC, whereas in the higher-risk patients closed by the RSS, MWC occurred in 26 (32%). CONCLUSIONS MWCs are frequent after preoperative RT and occur more commonly in patients with lower extremity tumors. The MWC rate observed in a single-institution setting was comparable to that observed in the preoperative therapy arm of a multicenter Canadian trial. Patients believed to be at higher risk for MWCs undergoing RSS closure have MWC rates comparable to those with lower-risk wounds closed by the primary team.

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 Correlations between various patient, tumor, and treatment characteristics and complications in patients undergoing combined modality treatment for primary lower extremity soft-tissue sarcomas were investigated. METHODS Using the M. D. Anderson Radiation Oncology database, the records of the subset of patients treated with combined radiation and limb-sparing surgery for primary lower extremity soft-tissue sarcomas were retrospectively reviewed from the years 1960 to 2003. RESULTS In all, 412 patients were identified. With a median follow-up of 9.3 years, there were a total of 113 (27%) acute wound complications and 41 (13% at 20 years) chronic radiation-related limb complications. Preoperative radiation and tumor sizes >5 cm were associated with an increased risk of acute wound complications (34% preoperative vs. 16% postoperative, P < .001; and 31% >5 cm vs. 17% < or =5 cm, P = .005). At 20 years the radiation-related complication rate was higher in patients with a groin or thigh tumor location (16% vs. 4% other; P = .008), prior acute wound complications (20% vs. 10% no surgical complication), and a radiation dose > or =60 grays (Gy) (18% vs. 9% for dose < 60 Gy; P = .04). Five fractures occurred, resulting in a crude overall fracture rate of 1.2%. CONCLUSIONS Patients treated with preoperative radiation for larger tumors are more likely to have acute surgical wound complications. Acute wound complications followed by postoperative radiation are associated with chronic radiation-related limb problems, as are higher radiation dose and proximal tumor location. The fracture rate is so low that prophylactic fixation is not warranted.

Abstract
BACKGROUND Limb-sparing surgery, consisting of wide-margin tumor resection and preoperative or postoperative radiotherapy/chemotherapy, has become the surgical treatment of choice for extremity sarcomas. However, adequate tumor resection can sometimes compromise crucial limb function, necessitating functional restoration surgery. The purpose of this study was to determine the cost impact and functional outcomes of such procedures. METHODS Patients receiving either functional restoration surgery or soft-tissue-only reconstruction following extremity soft-tissue sarcoma excision were identified. Patients were then compared along several dimensions: overall length of stay and its subdivisions, surgical time, and total charges and its subdivisions. Patients' functional outcomes were assessed with the Toronto Extremity Salvage Score. RESULTS Sixty-seven patients who underwent 69 limb-sparing procedures were identified. Fifteen of these procedures (eight upper extremity, seven lower extremity) required functional restoration surgery; 54 of these procedures (13 upper extremity, 41 lower extremity) required only soft-tissue coverage. In the upper extremity, there was a statistically significant increase in overall length of stay (2.8 days) and its subdivisions, surgical time (3.7 hours), and total charges (12,484 dollars) and its subdivisions associated with performing functional restoration surgery. In lower extremity cases, statistically significant increases were determined in only the total charges (9190 dollars) and medical supply charges (13,204 dollars) following functional restoration. Patients who underwent functional restoration surgery had better postoperative function (mean Toronto Extremity Salvage Score, 82 versus 80), but this difference was not statistically significant. CONCLUSION Although functional restoration surgery is more costly than soft-tissue reconstruction alone, the authors believe that the associated better functional outcome justifies its performance.

Abstract
PURPOSE TNFerade is a second-generation replication-deficient adenovector carrying a transgene encoding human tumor necrosis factor alpha under control of a radiation- induced promoter. The objective of this study was to assess the tolerance of combining TNFerade and radiation therapy in patients with soft tissue sarcomas of the extremity. EXPERIMENTAL DESIGN TNFerade was administered in combination with single-daily fractionated radiation therapy in 14 patients with soft tissue sarcoma of the extremities. Three escalating dose levels of TNFerade (4 x 10(9) -4 x 10(11) particle units) were planned, given in 1 log increments by intratumoral injections, twice weekly during week 1 and once weekly during weeks 2-5 of radiation therapy. RESULTS TNFerade was well tolerated with no dose-limiting toxicities noted. Grade 1-2 chills (50.0%), fever (43.0%), fatigue (36.0%), and flu-like symptoms (21.0%) were the most common side effects. Serum-tumor necrosis factor alpha levels were low in all of the patients (<15 pg/mL). No patients had virus-detected blood, sputum, or urine cultures. Of the 13 evaluable patients, 11 received TNFerade preoperatively, and 2 received the treatment for palliation. Eleven patients (85%) showed objective or pathological tumor responses (2 complete and 9 partial), and 1 had stable disease. Partial responses were achieved despite some of these tumors being very large (up to 675 cm(2)). Of the 11 patients who underwent surgery, 10 (91%) showed a pathological complete response/partial response. CONCLUSION TNFerade + radiation therapy was well tolerated in the treatment of patients with soft-tissue sarcoma of the extremity. The high number of objective responses observed warrants additional studies of this approach in a larger controlled prospective trial.

Abstract
PURPOSE Radiation (XRT) is a proven component in the treatment of soft tissue sarcoma. However, there is little evidence regarding the relative effectiveness of preoperative vs. postoperative XRT. This retrospective study addresses the relative effectiveness of disease control by these two treatment sequences. METHODS AND MATERIALS A total of 517 patients (246 treated with postoperative XRT, and 271 treated with preoperative XRT) with nonmetastatic sarcoma were evaluated for disease outcome and late complications using univariate and multivariate techniques. RESULTS With a median follow-up of 6 years, overall local control was 81% and 78% at 5 and 10 years, respectively. Although local control appeared superior with preoperative XRT (83% at 10 years) compared with postoperative XRT (72%), multivariate analysis revealed that this difference could be entirely explained by the unequal distribution of prognostic factors between the two groups, and there was no evidence that treatment sequence independently determined local control. There were no differences in nodal or metastatic relapse between the two treatments, and disease-specific survival was not significantly different. There was a slightly higher incidence of late XRT-related complications among those treated with postoperative XRT (10-year incidence of 9% vs. 5%, p = 0.03). CONCLUSIONS This study found no evidence for differences in disease outcome attributable to the use of either pre- or postoperative XRT. There was a slight increase in long-term complications with postoperative XRT, likely due to the higher doses used in this sequence.

Abstract
BACKGROUND Prognostic factors for patients with soft-tissue sarcoma who are treated with conservative surgery and radiation are documented poorly. METHODS The clinicopathologic features and disease outcome for 1225 patients with localized sarcoma who were treated with conservative surgery and radiation were reviewed retrospectively. Actuarial univariate and multivariate statistical methods were used to determine significant prognostic factors for local control, metastatic recurrence, and disease specific survival. RESULTS The median follow-up of surviving patients was 9.5 years. The respective local control rates at 5 years, 10 years, and 15 years were 83%, 80%, and 79%. Factors predictive of local recurrence were positive or uncertain resection margins; tumors located in the head and neck and the deep trunk; presentation with local recurrence; patient age > 64 years; malignant fibrous histiocytoma, neurogenic sarcoma. or epithelioid sarcoma histopathology; tumor measuring > 10 cm in greatest dimension; and high pathologic grade. Freedom from metastasis at 5 years, 10 years, and 15 years was 71%, 68%, and 66%, respectively. Factors that were predictive of metastatic recurrence were high tumor grade; large tumor size (> 5 cm); and leiomyosarcoma, rhabdomyosarcoma, synovial sarcoma, or epithelioid sarcoma. The respective disease specific survival rates at 5 years, 10 years, and 15 years were 73%, 68%, and 65%. Adverse factors for disease specific survival were high tumor grade; large tumor size (> 5 cm); tumors located in the head and neck and deep trunk; rhabdomyosarcoma, epithelioid sarcoma, or clear cell sarcoma; patient age > 64 years; and positive or uncertain resection margins. CONCLUSIONS Soft-tissue sarcoma comprises a heterogeneous group of diseases. Prognostic factors for local recurrence, metastatic recurrence, lymph node recurrence, disease free survival, and disease specific survival are different, and optimal treatment strategies need to take this complexity into account.

Abstract
PURPOSE To evaluate whether disease outcome for localized soft-tissue sarcoma (STS) excised before referral to a specialist center and there re-resected was influenced by the timing of radiation therapy (XRT)-before or after re-resection. MATERIALS AND METHODS Two hundred ninety-five consecutive patients with localized grossly excised STS were retrospectively evaluated for local control, freedom from metastasis, disease-free survival, and disease-specific survival, according to whether they had XRT before (121) or after (174) re-resection of their tumor bed. Univariate and multivariate statistical techniques were employed. RESULTS At re-resection, residual STS was found in 159 patients (54%), including gross tumor in 73 (25%). The incidence of residual disease was lower in those receiving preoperative XRT (median dose 50 Gy) (36%) than in those having postoperative RT (median dose 60 Gy) (54%) (p = 0.024). With a median follow-up of 9.1 years, the local control rates for all patients at 5, 10, and 15 years were 86%, 84%, and 81%, respectively, and there were no differences between the two XRT sequences. In multivariate regression, there was no evidence that XRT sequence influenced local control, metastatic control, disease-free survival, or disease-specific survival. There was a trend toward fewer XRT-related late complications with preoperative XRT, but this was not significant, and the incidence of complications was low (5% at 15 years). CONCLUSIONS Patients who present after total but oncologically inadequate excision of STS can receive approximately 50 Gy before re-resection or approximately 60 Gy after re-resection, with approximately equivalent, satisfactory local control and overall disease outcome. Decisions as to the most appropriate treatment sequence for any individual patient can be made regardless of considerations as to the effectiveness of one sequence compared with the other.
