Abstract
Well-differentiated liposarcomas (WDLPS) and dedifferentiated liposarcomas (DDLPS) account for 60 % of all liposarcomas, reflecting the heterogeneity of this type of sarcoma. Genetically, both types of liposarcomas are characterized by the amplification of MDM2 and CDK4 genes, which indicates an important molecular event with diagnostic and therapeutic relevance. In both localized WDLPS and DDLPS of the retroperitoneum and the extremities, between 25 % and 30 % of patients have local or distant recurrence, even when perioperatively treated, with clear margins present. The systemic treatment of WDLPS and DDLPS remains a challenge, with anthracyclines as the gold standard for first-line treatment. Several regimens have been tested with modest results regarding their efficacy. Herein we discuss the systemic treatment options for WDLPS and DDLPS and review their reported clinical efficacy results.

The role of neoadjuvant radiochemotherapy in the management of localized high-grade soft tissue sarcoma. Radiat Oncol 2022; 17:139. [PMID: 35941656 PMCID: PMC9361547 DOI: 10.1186/s13014-022-02106-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Accepted: 07/21/2022] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Standard treatment of soft tissue sarcoma (STS) of the extremities includes limb-sparing surgery combined with pre- or postoperative radiotherapy (RT). The role of perioperative chemotherapy (CTX) remains uncertain. STS patients with high-risk features for local recurrence, distant metastases, and increased mortality may require additional systemic therapy. The objective of this study was to evaluate predictors of outcome regarding local control (LC), overall survival (OS), and freedom from distant metastases (FFDM) in a large single-center cohort of patients suffering from localized high-grade STS (grade 2/3, G2/G3). Special emphasis was put on a subgroup of patients who received combined neoadjuvant radiochemotherapy (RCT). METHODS Overall, 115 adult STS patients were included in this retrospective study. The median follow-up was 34 months. Twenty-three patients (20.0%) were treated with neoadjuvant RCT, 92 (80.0%) received other therapies (adjuvant RT alone (n = 58); neoadjuvant CTX + adjuvant RT (n = 17); adjuvant RCT (n = 10), neoadjuvant RT alone (n = 7)). To assess potential prognostic factors on LC, OS, and FFDM, univariate (UVA) and multivariable (MVA) Cox proportional hazards models were applied. RESULTS UVA showed significantly better LC rates in the neoadjuvant RCT group (p = 0.025), with trends in MVA (p = 0.057). The 3-year LC rate was 89.7% in the neoadjuvant RCT group vs. 75.6% in the "other therapies" group. UVA also showed significantly better OS rates in the neoadjuvant RCT group (p = 0.049), however, this was not confirmed in MVA (p = 0.205), the 3-year OS rate was 85.8% for patients treated with neoadjuvant RCT compared to 73.5% in the "other therapies" group. UVA showed significantly better FFDM rates in (p = 0.018) and a trend towards better FFDM rates in MVA (p = 0.059). The 3-year FFDM rate was 89.7% for patients treated with neoadjuvant RCT compared to 65.9% in the "other therapies" group. In the subgroup of patients with G3 STS, neoadjuvant RCT was a significant positive predictor of LC and FFDM in MVA (p = 0.047, p = 0.027) but not for OS. Overall grade 3 and 4 toxicities were significantly higher (p = 0.019) in the neoadjuvant RCT group and occurred in 73.9% vs. 38.0% in patients receiving other therapies. CONCLUSIONS The results suggest that neoadjuvant RCT might improve LC and FFDM in patients with localized G3 STS while also being associated with increased acute complication rates. Further prospective research is warranted to confirm these findings.

Abstract
Soft tissue sarcomas (STS) are rare malignancies of mesenchymal cell origin that display a heterogenous mix of clinical and pathologic characteristics. STS can develop from fat, muscle, nerves, blood vessels, and other connective tissues. The evaluation and treatment of patients with STS requires a multidisciplinary team with demonstrated expertise in the management of these tumors. The complete NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Soft Tissue Sarcoma provide recommendations for the diagnosis, evaluation, and treatment of extremity/superficial trunk/head and neck STS, as well as retroperitoneal/intra-abdominal STS, desmoid tumors, and rhabdomyosarcoma. This portion of the NCCN Guidelines discusses general principles for the diagnosis and treatment of retroperitoneal/intra-abdominal STS, outlines treatment recommendations, and reviews the evidence to support the guidelines recommendations.

Abstract
PURPOSE Localized adult high-grade soft tissue sarcomas (STS) usually require multimodality treatment including surgery, radiotherapy, chemotherapy and hyperthermia. If maximal preoperative tumor-shrinkage is envisaged, neoadjuvant chemotherapy + radiation (CRT) is often applied, however at the expense of relatively high toxicities and increased postoperative complication rates. This study aims to compare preoperative CRT with neoadjuvant chemotherapy + regional hyperthermia (HCT) regarding histopathological response, toxicity and outcome. METHODS In this retrospective analysis, 61 consecutive high-grade STS patients treated between 2009 and 2016 were included. All patients were treated within a prospective treatment protocol. 28 patients received neoadjuvant CRT 33 patients HCT. CRT consisted of four cycles doxorubicin/ifosfamide and two cycles ifosfamide concomitant to 50.4 Gray external beam radiotherapy. HCT consisted of 4-6 cycles doxorubicin/ifosfamide with deep regional hyperthermia administered bi-weekly during each cycle. Association of treatment modality with overall survival (OS), local control (LC) and freedom from distant metastases (FFDM) was evaluated by Kaplan-Meier and log-rank analyses. RESULTS The overall patient characteristics were well balanced. Histopathological tumor response did not differ significantly between both groups (p = .67), neither did higher-grade toxicities during neoadjuvant treatment. Wound dehiscence (p = .018) and surgical hospital re-admissions (p < .001) were both significantly more frequent in the CRT group. Two-year OS, LC and FFDM rates of all patients were 93, 85 and 71% with no significant differences between CRT and HCT. CONCLUSION Compared to CRT, HCT seems equally efficient and appears to bear less surgical complications. Interpretation should be cautious due to the low number of patients and the retrospective nature of this study.

Abstract
Here, we present the case of a 78-year-old male patient with undifferentiated spindle cell sarcoma on the posteromedial surface of the right leg who experienced a long-lasting progression-free survival. Due to an underlying cardiac disease, the patient was not suitable for anthracyclines. In September 2015, he received first-line chemotherapy with trabectedin (Yondelis®) at the approved dosage and regimen - concomitant with external radiotherapy (RT). After the first 9 cycles of trabectedin plus RT given in the neoadjuvant setting, the patient underwent surgical resection. At that stage, we observed a very good pathological response with 80% of necrotic area. The patient resumed the therapy with trabectedin; however, approximately 5 months later, we observed a new nodular heterogeneous lesion with ill-defined margins in the right leg and suggestive of tumor relapse. Subsequently an above-the-knee amputation was performed, and the patient resumed his trabectedin therapy with the same dosage and regimen. In January 2018, almost 2 1/2 years after the start of trabectedin treatment and 30+ cycles of trabectedin, the patient is locoregionally and distant metastatically disease-free. Currently, the treatment with trabectedin is maintained without any significant serious toxicity. Future clinical trials are needed to gain additional insights into the role of trabectedin maintenance therapy until disease progression in the neoadjuvant setting and to identify predictive and prognostic criteria for response to trabectedin in patients with advanced sarcoma.

Abstract
Soft tissue sarcomas (STS) are rare and heterogeneous tumours. A correct definition of STS is imperative from the very beginning of disease management, to guide the diagnostic and imaging work-up, and help to establish the prognosis on which the therapeutic strategy will be based. Over the last few years, many efforts have been made to identify characteristics that could predict disease behaviour and to enrich the therapeutic armamentarium against the advanced disease, that is still characterised by poor prognosis. Surgery remains the milestone of treatment for localised STS, whereas many uncertainties regarding the role of adjuvant and neoadjuvant treatment persist. Some controlled evidence is available, but often conflicting and insufficient to make chemotherapy (CT) a standard practice and, currently, a common and shared strategy does not exist. The biggest question concerns the prospective identification of the subgroup of patients who would benefit the most from (neo)adjuvant therapies. In light of the growing understanding of different biologies and sensitivities of the various sarcoma subtypes, the value of histology in the selection of peri-operative treatments is one of the most intriguing topics under discussion. In this perspective, a new generation of neoadjuvant trials have been planned and are currently ongoing. The aim of this review was to rekindle interest in the long-standing topic of (neo)adjuvant CT in localised STS, providing an update on its role in sarcomas' management and highlighting future directions and consequential factors needed to further improve outcomes in this disease.

Abstract
PURPOSE To determine if aerosol granulocyte macrophage-colony-stimulating factor (GM-CSF) decreases the 2-year pulmonary metastasis rate for soft tissue sarcoma. PATIENTS AND METHODS Patients with high-grade soft tissue sarcomas were treated with 2 cycles of ifosfamide, mitomycin, doxorubicin, and cisplatin plus GM-CSF subcutaneous followed by 45 Gy irradiation with concurrent 2 cycles of mitomycin, doxorubicin, and cisplatin followed by surgery +/- intraoperative radiation or brachytherapy. Aerosol GM-CSF (250 mcg twice a day) was administered for 1 week every other week 3× during neoadjuvant therapy and beginning 4 weeks postoperatively every other week 5×. RESULTS A total of 39 patients were enrolled between November 2001 and April 2006. The median age was 51 years (range, 19 to 65 y). The median lesion size was 9 cm (range, 2.3 to 26.7 cm). Seventy-six percent experienced grade 3-4 hematologic toxicity. Twenty-four of the first 35 evaluable patients (69%; 95% CI, 41%-84%) were free of pulmonary metastasis at 2 years. A total of 82% (95% CI, 70%-95%) of patients were still alive after 3 years, with a median follow-up of 5.5 years (range, 3.4 to 7.6 y). A total of 58% (95% CI, 44%-76%) of patients remained progression free after 3 years. CONCLUSIONS The addition of aerosol GM-CSF to combined chemotherapy, irradiation, and surgery for soft tissue sarcomas did not achieve the study endpoint to decrease the 2-year pulmonary metastasis rate.

Abstract
BACKGROUND This study was performed to determine the maximum tolerated dose (MTD) of gemcitabine given concurrently with preoperative, fixed-dose external-beam radiation therapy (EBRT) for patients with resectable, high-risk extremity and trunk soft tissue sarcoma (STS). METHODS Gemcitabine was administered on days 1, 8, 22, 29, 43, and 50 with EBRT (50 Gy in 25 fractions over 5 weeks). The gemcitabine MTD was determined with a toxicity severity weight method (TSWM) incorporating 6 toxicity types. The TSWM is a Bayesian procedure that choses each cohort's dose to have a posterior mean total toxicity burden closest to a predetermined clinician-defined target. Clinicopathologic and outcome data were also collected. RESULTS Thirty-six patients completed the study. According to the TSWM, the gemcitabine MTD was 700 mg/m(2). At this dose level, 4 patients (24%) experienced grade 4 toxicity; no toxicity-related deaths occurred. All tumors were resected with microscopically negative margins. Pathologic responses of >90% tumor necrosis were achieved in 17 patients (47%); 14 (39%) had complete responses. With a median follow-up of 6.2 years, the 5-year locoregional recurrence-free survival, distant metastasis-free survival, and overall survival rates were 85%, 80%, and 86%, respectively. CONCLUSIONS The TSWM combines data from qualitatively different toxicities and can be used to determine the MTD for a drug given as part of a multimodality treatment. Neoadjuvant gemcitabine plus radiation therapy is feasible and safe in patients with high-risk extremity and trunk STS. Major pathologic responses can be achieved, and after complete resection, long-term clinical outcomes are encouraging.

Abstract
BACKGROUND Mesenchymal malignancies of salivary origin are rare and are histologically diverse. We reviewed our experience with these tumors, as well as the published literature, with an emphasis on treatment modalities and prognosis. METHODS We identified 17 patients treated for malignant mesenchymal cell tumors at The University of Texas MD Anderson Cancer Center between 1990 and 2007. We compared our results to the literature from January 1990 to July 2010. RESULTS Tumors were located primarily in the parotid gland and were primarily T1 tumors (<5 cm). All patients were treated with surgical resection, and 13 patients were given adjuvant therapy. Seven patients (41%) had recurrence, and 4 developed distant metastases. The overall 5-year and 10-year survival rates were 42% and 20%, respectively. CONCLUSIONS Our case series and literature review show that sarcomas of the salivary glands have a high rate of recurrence and are associated with a poor prognosis.

Abstract
BACKGROUND Approximately 10% of soft tissue sarcomas (STS) occur in the most distal parts of the extremities. The standard therapy is local excision with adjuvant radiotherapy, but achieving wide resection margins might be difficult in the distal parts of the limb. Tumor necrosis factor-alpha (TNF) and melphalan-based isolated limb perfusion (TM-ILP) is effective in locally advanced STS of the extremities. We report the results of TM-ILP for STS in the most distal parts of the limb. METHODS Between 1991 and 2009, 34 ILPs were performed in patients with irresectable STS of the wrist, hand, ankle, or foot. Disease was unifocal in 21 (62%) patients. RESULTS Overall response rate was 71% (n = 24). After a median follow-up of 34 (range 1-143) months the local recurrence rate was 32%. Amputation was unavoidable in four patients (13%), four other patients (13%) underwent a partial amputation of the hand or foot. CONCLUSION With a limb salvage rate of 87%, TM-ILP is an effective treatment modality in patients with distal STS. In all patients with an indication for amputation surgery due to an STS in the distal part of the limb, TM-ILP should be considered.

Abstract
PURPOSE Because there is no survival benefit of amputation for extremity soft tissue sarcomas (STSs), limb-sparing surgery has become the gold standard. Tumor size reduction by induction therapy to render nonresectable tumors resectable or facilitate function-preserving surgery can be achieved by tumor necrosis factor α (TNF) -based and melphalan-based isolated limb perfusion (TM-ILP). This study reports the long-term results of 231 TM-ILPs for locally advanced extremity STS. PATIENTS AND METHODS We analyzed 231 TM-ILPs in 208 consecutive patients (1991 to 2005), who were all candidates for functional or anatomic amputation for locally advanced extremity STS. All patients had a potential follow-up of up to 5 years. TM-ILP was performed under mild hyperthermic conditions with 1 to 4 mg of TNF and 10 to 13 mg/L of limb-volume melphalan. Almost all patients (85%) had intermediate- or high-grade tumors. RESULTS The overall response rate (ORR) was 71% (complete response, 18%; partial response, 53%). Multifocal sarcomas had a significantly better ORR of 83% (P = .008). The local recurrence rate was 30% (n = 70); local recurrence rates were highest for multifocal tumors (54%; P = .001) and after previous radiotherapy (54%; P < .001). Five-year overall survival rate was 42%. Survival was poorest in patients with large tumors (P = .01) and with leiomyosarcomas (P < .001). Limb salvage rate was 81%. CONCLUSION We demonstrated that TM-ILP results in a limb salvage rate of 81% in patients with locally advanced extremity STS who would otherwise have undergone amputation. Whenever an amputation is deemed necessary to obtain local control of an extremity STS, TM-ILP should be considered.

Abstract
BACKGROUND Neoadjuvant chemoradiation (NCR) prior to resection of extremity soft tissue sarcoma (STS) has been studied, but data are limited. We present outcomes with NCR using a variety of chemotherapy regimens compared to neoadjuvant radiation without chemotherapy (NR) and surgery alone (SA). METHODS We conducted a retrospective chart review of 112 cases. RESULTS Treatments included SA (36 patients), NCR (39 patients), and NR (37 patients). NCR did not improve the rate of margin-negative resections over SA or NR. Loco-regional relapse-free survival, distant metastases-free survival, and overall survival (OS) were not different among the treatment groups. Patients with relapsed disease (OR 11.6; p = 0.01), and tumor size greater than 5 cm (OR 9.4; p = 0.01) were more likely to have a loco-regional recurrence on logistic regression analysis. Significantly increased OS was found among NCR-treated patients with tumors greater than 5 cm compared to SA (3 year OS 69 vs. 40%; p = 0.03). Wound complication rates were higher after NCR compared to SA (50 vs. 11%; p = 0.003) but not compared to NR (p = 0.36). Wet desquamation was the most common adverse event of NCR. CONCLUSIONS NCR and NR are acceptable strategies for patients with STS. NCR is well-tolerated, but not clearly superior to NR.

Abstract
Neoadjuvant or adjuvant therapy in soft tissue sarcomas is still controversial, especially in regards to the use of chemotherapy. The identification of predictive factors is crucial to avoid the use of chemotherapy in patients with tumors that carry genetic characteristics associated with resistance. Focusing on gene expression data, we performed a review of the actual state of knowledge in molecular predictive factors for chemotherapy response and new targets of therapy in extremity sarcomas.

Abstract
INTRODUCTION AND OBJECTIVE Neoadjuvant and adjuvant therapies for soft tissue sarcomas of the extremities are still controversial. The aim of this study was to analyze the results of a protocol of neoadjuvant chemoradiation therapy for extremity sarcomas. METHODS A retrospective analysis was carried out in a consecutive series of 49 adult patients with advanced extremity soft tissue sarcomas that could not be resected with adequate margins during the primary resection. All patients were treated with a protocol of preoperative radiation therapy at a total dose of 30 Gy, concomitant with doxorubicin (60 mg/m(2)) chemotherapy. The main endpoints assessed were local recurrence-free survival, metastasis-free survival and overall survival. The median follow-up time was 32.1 months. RESULTS The five-year local recurrence-free survival, metastasis-free survival and overall survival rates were 81.5%, 46.7% and 58.3%, respectively. For high-grade tumors, the five-year metastasis-free and overall survival rates were only 36.3% and 41.2%, respectively. Severe wound complications were observed in 41.8% of the patients who underwent surgery. These complications precluded adjuvant chemotherapy in 73.7% (14/19) of the patients eligible to receive it. CONCLUSIONS In this study, neoadjuvant chemoradiation therapy was associated with a good local control rate, but the distant relapse-free rate and overall survival rate were still poor. The high rate of wound complications modified the planning of adjuvant treatment in most patients.

Abstract
BACKGROUND Isolated limb infusion (ILI) is a minimally invasive technique for delivering high-dose regional chemotherapy. We report our experience with ILI for the treatment of soft tissue sarcoma (STS). METHODS From our prospective database, 21 patients with STS of the limb treated with ILI between 1994 and 2007 were identified. In all patients, a high-dose cytotoxic drug combination was used. RESULTS There were 14 men, and the median age was 60 years (range, 18-85 years). Eighteen patients (86%) had lower limb tumors. All patients had advanced local disease. The procedure was well tolerated. Fourteen patients (67%) received ILI before definitive surgery. The overall response rate was 90% (complete response [CR] rate 57%, partial response rate 33%). The disease-specific overall survival was 61.9% (median follow-up, 28 months). Only American Joint Committee on Cancer stage was associated with overall survival. The local recurrence rate was 42%. CR and malignant fibrous histiocytoma tumor subtype were associated with a lower local recurrence rate. A lower initial skin temperature (median 35.8 degrees C) was associated with a CR (P = .033). Patients who had a steep increase in intramuscular temperature during the procedure were more likely to have a CR (P = .055). Classification tree analysis identified patients with an initial PaO(2) of >/=194 mmHg as being more likely to have a CR. Ultimately, the overall limb salvage rate was 76%. CONCLUSION The outcomes after ILI are comparable to those achieved by conventional isolated limb perfusion. ILI is a minimally invasive alternative to isolated limb perfusion for patients with advanced STS of the extremity.

Abstract
Isolated limb perfusion (ILP) with chemotherapy alone has uniformly failed in the treatment of irresectable extremity soft tissue sarcomas. The addition of tumor necrosis factor-alpha (TNF-α) to this treatment approach contributed to a major step forward in the treatment of locally advanced extremity soft tissue sarcoma (STS). High response rates and limb salvage rates have been reported in multicenter trials, which combined ILP with TNF-α plus melphalan, which resulted in the approval of TNF-α for this indication in Europe in 1998. Subsequently a series of confirmatory single institution reports on the efficacy of the procedure have now been published. TNF-α has an early and a late effect; it enhances tumor-selective drug uptake during the perfusion and plays an essential role in the subsequent selective destruction of the tumor vasculature. These effects result in a high response rate in high-grade soft tissue sarcomas. This induction therapy thus allows for resection of tumor remnants some 3 months after ILP and thus avoidance of limb amputation. TNF-α-based ILP is a well-established treatment to avoid amputations. It represents an important example of tumor vasculatory-modulating combination therapy and should be offered in large volume tertiary referral centers.

Abstract
Cervical cancer is the seventh most frequent cancer worldwide but more than 80% of cases occur in developing countries. Till date, radiation therapy with external beam and brachytherapy remains as the core treatment for most stages of cervical cancer. However, radiation treatment protocols and equipment modelled on the best developed countries can be seldom applied directly to developing countries owing to financial constraints and lack of qualified personnel, thus, a substantial proportion of patients do not have access to even palliative radiation therapy. Treatment options when the standard therapy is either not available or difficult to reproduce in particular settings is highly desirable with the potential to save lives that otherwise could be lost by the lack of adequate treatment. These options of treatment ideally had to have show, 1) that these are not inferior to the "standard" in terms of either survival or quality of life; 2) that these can be delivered in settings were the "standard" is not available or if available its quality is poor; and 3) that the treatment option be accepted by the population to be treated. Based on these considerations, it is obvious that cervical cancer patients, particularly those who live in countries with limited resources and therefore may not have sufficient radiation therapy resources are in need of newer therapeutical options. There is now a considerable amount of information emanating from clinical studies where surgery has a major role in treating this disease. These forms of "radiation-sparing" treatments include total mesometrial resection that could make unnecessary the use of adjuvant radiation; neoadjuvant chemotherapy that could avoid the use of adjuvant radiation in around 85% of patients and preoperative chemoradiation that could make brachytherapy dispensable. The feasibility and therapeutical value of these potential forms of management need to be prospectively evaluated.

Abstract
BACKGROUND At present, limb-sparing surgery is the most appropriate and acceptable treatment option for soft tissue sarcomas of the extremities. To increase the number of limb-sparing resections in the treatment of locally advanced soft tissue sarcomas of the extremities, preoperative radiotherapy and/or chemotherapy are often used. Isolated limb perfusion of cytostatic agents is an effective alternative option but technically complex. Isolated limb infusion, essentially a low-flow isolated limb perfusion without oxygenation via a percutaneous catheter, had been developed as a simple alternative. OBJECTIVE The objective of this study was to achieve limb-sparing surgery in patients with locally advanced soft tissue sarcomas of the extremities that would otherwise have required an amputation or a functionally mutilating surgery by performing preoperative isolated limb infusion with doxorubicin and external beam irradiation to obtain local control and make limb-sparing surgery feasible. METHODS A total of 40 patients with locally advanced soft tissue sarcomas of the extremities were evaluated between 2002 and 2005. Tumors were located in the lower limb in 28 patients (70%) and in the upper limb in 12 patients (30%). All of these patients were felt to be unresectable and were referred because amputation was considered the only available treatment option. They underwent preoperative isolated limb infusion with doxorubicin (0.7 and 1.4 mg/kg for the upper and lower limbs, respectively). Preoperative external beam radiotherapy started within 3-7 days after isolated limb infusion was administered. The total dose was 35 Gy in ten fractions. After 3-7 weeks, surgery was performed aiming at limb preservation. RESULTS Tumor response was seen in 85% of patients, rendering these large sarcomas resectable in most cases. The mean values of pretreatment tumor volume and post-treatment volume were 2797 cm(3) and 1781 cm(3), respectively, with a significant p value of 0.0001. Histologic response was seen in 80% of patients. At a median followup of 15 months (range = 5-35), limb salvage was achieved in 82.5%. Procedure-related complications were limited and easily managed. CONCLUSION Isolated limb infusion with doxorubicin is a simple and safe method of regional chemotherapy. The addition of preoperative external beam irradiation helped to increase the rate of limb salvage in patients with large and/or high-grade soft tissue sarcomas of the extremities.

Abstract
INTRODUCTION Involvement of major vascular structures has been considered a limiting factor for resecting advanced tumors. The objective of this study was to evaluate the outcome after concomitant retroperitoneal tumor and vascular resection with prosthetic replacement of the aorta/vena cava. METHODS The authors reviewed a 5-year series of eight patients with a median age of 50 years (range 11-68 years) who had undergone resection of a retroperitoneal tumor and concomitant resection and replacement of the abdominal aorta, inferior vena cava, or both. The histologic diagnoses were sarcoma (five patients), teratoma (one), transitional cell carcinoma (one), and ganglioneuroma (one). The main outcome measures were early (<30 days) and late (>or=30 days) surgical morbidity and mortality. Secondary endpoints were vascular graft patency and tumor-free survival. Two patients underwent combined graft replacement of the aorta and vena cava. Single aortic and vena cava graft replacement were each done in three patients. RESULTS Two patients showed early surgical morbidity necessitating reoperation for a thrombotic graft occlusion. No patient died during the early course of the follow-up. During a median follow-up of 14 months (range 1-56 months), two patients had late surgical morbidity. The median tumor-free survival for patients with malignancy was 14 months (range 1-54 months). One patient developed locoregional tumor recurrence, and two developed distant metastases. The median survival for patients with malignancy was 14 months (range 1-60 months). CONCLUSIONS An aggressive surgical approach for otherwise unresectable retroperitoneal tumors with vascular resection and prosthetic vascular replacement is justified in selected cases and has acceptable morbidity and mortality.

Abstract
BACKGROUND AND OBJECTIVES To analyze treatment and survival in 34 patients (28 resected) with primary or recurrent retroperitoneal sarcoma (RPS). METHODS Between July 1994 and January 2001, 34 patients (15M, 19F; mean age: 56 years, range: 25-77) were evaluated. Complete resection was defined as removal of gross tumor with histologically confirmed clear resection margins. RESULTS Twenty-eight out of 34 patients (82%) (15 were affected by primary RPS, and 13 by recurrent RPS), underwent surgical exploration. Twenty-three patients had a grossly and microscopically complete resection, (3 having a grossly incomplete resection and 2 patients with a grossly complete resection having histologically involved resection margins). Twenty-one out of 28 patients (75%) underwent removal of contiguous intra-abdominal organs. Preoperative mortality was nil, and morbidity occurred in six cases only (21%). High tumor grade results a significant variable for a worse survival in all 28 patients (100% 5 years survival for low grade vs. 0% for high grade; P = 0.0004). Amongst completely resected patients, only histologic grade and peroperative blood transfusions affected disease-free survival (P = 0.04 and P = 0.05, respectively). CONCLUSIONS An aggressive surgical approach in both primary and recurrent RPS is associated with long-term survival.

Abstract
Isolated limb perfusion (ILP) with melphalan is effective in the treatment of small multiple melanoma intransit metastases and is utilized widely for this indication. The treatment is much less effective against bulky melanoma metastases and has uniformly failed in the treatment of irresectable extremity soft tissue sarcomas. The addition of tumor-necrosis factor-alpha (TNF-alpha) to this treatment approach has changed the situation dramatically. High response rates and limb-salvage rates have been reported in multicenter trials that combined ILP with TNF-alpha plus melphalan; these trials resulted in the approval of TNF-alpha for bulky melanoma metastases and soft tissue sarcomas in Europe in 1998. Subsequently, many doctors working in European centers have been trained, and a series of confirmatory reports from single institutions have now been published regarding the efficacy of the procedure. TNF-alpha has an early and a late effect; it enhances tumor-selective drug uptake during the perfusion, and plays an essential role in the subsequent selective destruction of the tumor vasculature. These effects result in a high response rate in bulky tumors, soft tissue sarcomas, bulky melanomas, and various other tumor types. This induction therapy therefore allows tumor remnants to be resected some 3 months after ILP thus avoiding limb amputation. TNF-alpha-based ILP is a well-established treatment that aims to avoid amputations regardless of the tumor size and type. It represents an important example of combination therapy that modulates the tumor vasculature and should be offered in high-volume tertiary referral centers.

Abstract
The therapeutic approach to soft tissue sarcomas (STS) has evolved over the past two decades based on the results from randomized controlled trials, which are guiding physicians in the treatment decision-making process. Despite significant improvements in the control of local disease, a significant number of patients ultimately die of recurrent/metastatic disease following radical surgery due to a lack of effective adjuvant treatments. In addition, the characteristic chemoresistance of STS has compromised the therapeutic value of conventional antineoplastic agents in cases of unresectable advanced/metastatic disease. Therefore, novel therapeutic strategies are urgently needed to improve the prognosis of patients with STS. Recent advances in STS biology are paving the way to the development of molecularly targeted therapeutic strategies, the efficacy of which relies not only on the knowledge of the molecular mechanisms underlying cancer development/progression but also on the personalization of the therapeutic regimen according to the molecular features of individual tumours. In this work, we review the state-of-the-art of conventional treatments for STS and summarize the most promising findings in the development of molecularly targeted therapeutic approaches.

Abstract
BACKGROUND Extensive and mutilating surgery is often required for locally advanced soft tissue sarcoma (STS) of the limb. As it has become apparent that amputation for STS does not improve survival rates, the interest in limb-preserving approaches has increased. Isolated limb perfusion (ILP) with tumor necrosis factor-alpha (TNF) and melphalan is successful in providing local tumor control and enables limb-preserving surgery in a majority of cases. A mature, large, single-institution experience with 217 consecutive ILPs for STS of the extremity is reported. METHODS At a prospectively maintained database at a tertiary referral center, 217 ILPs were performed from July 1991 to July 2003 in 197 patients with locally advanced STS of the extremity. ILPs were performed at mild hyperthermic conditions with 1-4 mg of TNF and 10-13 mg/L limb-volume melphalan (M) for leg and arm perfusions, respectively. RESULTS The overall response rate was 75%. Limb salvage was achieved in 87% of the perfused limbs. Median survival post-ILP was 57 months and prognostic factors for survival were Trojani grade of the tumor and ILP for single versus multiple STS. The procedure could be performed safely, with a perioperative mortality of 0.5% in all patients with no age limit (median age, 54 yrs; range, 12-91). Systemic and locoregional toxicity were modest and easily manageable. CONCLUSION TNF+M-based ILP can provide limb salvage in a significant percentage of patients with locally advanced STS and has therefore gained a permanent place in the multimodality treatment of STS.

Abstract
Retroperitoneal sarcomas are rare neoplasms. CT or MR imaging is performed in patients with these tumors to detect local extent and distant metastases of the tumor and for preoperative surgical planning. Most sarcomas cannot be characterized as to cell type with CT or MR, with the exceptions being liposarcomas and intracaval leiomyosarcomas. Similarly histological grading cannot be made definitively with imaging alone, the exception being liposarcoma since well differentiated liposarcomas contain more macroscopic fat than do less differentiated liposarcomas. After surgery, follow up imaging with CT or MR and careful scrutiny of the tumor bed and resection site are essential to detect early recurrences, which can often be managed with re-resection.

Abstract
BACKGROUND In the management of retroperitoneal sarcomas it is necessary to achieve local control to ensure survival. The role of adjuvant radiation therapy (RT), either pre- or postoperative, remains controversial. METHODS Outcomes for 40 patients with retroperitoneal sarcoma treated with surgery and postoperative RT (n = 25) or preoperative RT (n = 15) were analyzed for variables prognostic for local control, survival, and associated complications. RESULTS Patterns of failure for patients treated by resection and postoperative RT were local (n = 4), local and distant (n = 3), and distant (n = 3). The failure patterns for preoperative RT cases were local (n = 2), local and distant (n = 2); and distant (n = 4). Median time to local recurrence in the postoperative and preoperative RT series were 1 year and 2.5 years respectively. The margin status was predictive for local control (P = 0.0065) and survival (P = 0.0012), regardless of treatment sequence. Absolute 5-year survival was 12% with positive margins versus 69% if negative. Histologic grade was indicative of the risk for distant metastasis (low grade 8% vs high grade 64%; P = 0.1373), and significantly predicted 5-year absolute survival (low grade 77% vs high grade 34%; P = 0.0267). Postoperative RT was associated with significant complications (infection, hemorrhage, and bowel obstruction--2 cases each). CONCLUSION Compared with the surgery-alone series, adjuvant RT appears to improve the probability of local control. Preoperative RT may be the preferred sequence potentially to improve tumor resectability and local-regional control with less risk of complications than with postoperative RT.

Abstract
BACKGROUND Factors prognostic for survival in patients with locally recurrent extremity soft tissue sarcomas (STS) are poorly defined, thus making it difficult to identify high-risk patients who may benefit from adjuvant therapy. METHODS A total of 1421 patients underwent surgical treatment for primary extremity STS at a single institution between 1982 and 2002. Of these, 179 (13%) patients underwent complete surgical resection of an isolated local recurrence and were the subjects of this study. Clinicopathologic factors from both the primary tumor and the local recurrence were analyzed. RESULTS The median interval to initial local recurrence was 16 months: 65% developed a local recurrence by 2 years and 90% by 4 years. Only four patients who presented with a low-grade primary tumor progressed to a high-grade local recurrence. Independent prognostic factors for disease-specific survival after local recurrence were a high histological grade (hazard ratio, 5.1; P = .0004), a large local recurrence tumor size (hazard ratio, 1.5; P = .0001), and a short local recurrence-free interval (hazard ratio, 1.6; P = .0001). Patients who developed a local recurrence >5 cm in < or =16 months (n = 44; 0 low grade) had a 4-year disease-specific survival of 18%, compared with 81% for patients who developed a local recurrence < or =5 cm in >16 months (n = 46; 11 low grade). CONCLUSIONS Histological grade, local recurrence size, and local recurrence-free interval are independently predictive of survival in patients with locally recurrent extremity STS. A large local recurrence that develops in a short interval indicates a biologically aggressive tumor with a high tumor-specific mortality. Patients who develop such recurrences are ideal subjects for systemic neoadjuvant therapy trials.

Abstract
PURPOSE To compare gemcitabine and cisplatin (GC) with cisplatin (C) concurrent with radiotherapy in International Federation of Gynecology and Obstetrics Stage IB2, IIA, and IIB cervical carcinoma in a preoperative setting. The main endpoints were the pathologic response rate and toxicity. METHODS AND MATERIALS A total of 83 patients were randomized to either C or GC. Treatment consisted of six doses of cisplatin at 40 mg/m(2) every week for Arm 1 (C) and six doses of gemcitabine at 125 mg/m(2) plus cisplatin at 40 mg/m(2) every week for or Arm 2 (GC) Both regimens were administered concurrent with 50 Gy of external beam radiotherapy in 2-Gy fractions for 5 weeks. After chemoradiotherapy, patients underwent radical hysterectomy. RESULTS All 83 patients were studied for toxicity and 80 for response. The complete pathologic response rate in the C arm and GC arm was 55% (95% confidence interval, 35.5-73%) and 77.5% (95% confidence interval, 57-90%; p = 0.0201). Among those with a partial response, 7 patients each had high and intermediate-high risk factors for recurrence in their surgical specimens in the C arm vs. 2 and 3 patients, respectively, with these characteristics in the CG arm. The number of weekly doses and the dose intensity of GC were lower than for C. The time to complete external beam radiotherapy also favored the C arm. The CG combination produced greater GI and hematologic toxicity. CONCLUSION The radiosensitizing combination of GC achieved a greater pathologic response rate than C in the treatment of cervical cancer.

Abstract
BACKGROUND The objective of this study was to assess long-term prognosis and patterns of failure in patients with retroperitoneal soft tissue sarcoma who underwent surgery with curative intent at a single institution. Several series of patients with retroperitoneal sarcoma were reported, providing widely variable data regarding local and distant failure. METHODS Overall, 167 consecutive patients who underwent surgery for retroperitoneal soft tissue sarcoma over a 20 year span at a single referral center were reviewed retrospectively. Eighty-two patients presented with primary disease, whereas 85 patients had recurrent locoregional tumors. Surgical resection was considered macroscopically complete in 147 of 167 patients (88%). RESULTS Overall survival at 10 years after definitive surgery was approximately 27%, and the disease-free survival was approximately 16%. Only a minority of patients developed distant metastases. The risk of recurrence was correlated with whether patients underwent surgery for primary disease or for recurrent disease; the 10 year disease-free survival rate was 27% in the former group and 4.6% in the latter group. Histotype and malignancy grade were other prognostic factors, with the former found to be predictive of the pattern of failure and the latter predictive of overall survival. CONCLUSIONS Local recurrence after primary surgery and high-grade malignancy were associated with the worst survival. Histologic subtype appeared to influence the pattern of recurrence, which mainly was local for patients with liposarcoma but was both local and distant for patients with the other histotypes.

Abstract
Radiation was until recently the key and only modality for the routine treatment of locally advanced cervical carcinoma. However after years of studying multi-modality treatments as an alternative to radiation alone in randomized phase III trials, the standard treatment has changed to chemo-radiation based on cisplatin. Three recent meta-analyses have confirmed that cisplatin-based chemo-radiation adds an absolute 12% benefit in five-year survival over radiation therapy alone. Neoadjuvant chemotherapy followed by radiation has not been of proven benefit, but when neoadjuvant chemotherapy is followed by surgery, an absolute increase of 15% in five-year survival over radiation alone is seen. This benefit in survival is comparable to that obtained with the current chemo-radiation schedules based on cisplatin. Despite these encouraging results there remains room for improvement as the five-year survival of patients treated with chemo-radiation ranges from nearly 80% in bulky IB tumours to only 25% in stage IVA disease. Other therapeutic approaches need to be fully evaluated including the use of chemo-radiation after neoadjuvant chemotherapy; the use of new drug combinations and the multi-modality combination of neoadjuvant chemotherapy followed by radical surgery plus adjuvant chemo-radiation. Likewise, the addition of radiosensitizers to cisplatin, preoperative chemo-radiation and/or adjuvant chemotherapy may eventually improve the currents results of cisplatin-based chemo-radiation. Nevertheless, it is hard to foresee a dramatic increase in cure rate, even with the most optimal combination of cytotoxic drugs, surgery and radiation, and thus the testing of molecular targeted therapies against cervical cancer is a logical step to follow.

Abstract
To achieve the ultimate goal of cancer treatment, which is 100% cancer control with negligible toxicity, the therapeutic window must be enlarged, allowing for higher doses of beneficial treatments with reduced toxicity. The advent of image- and metabolism-guided therapy offers the best opportunity to date for combining modern radiation targeting and imaging techniques. Indeed, for the first time, it is reasonable to locally target metastatic disease with the goal of sterilization. Combining these focal radiation techniques with novel targeted antiproliferative agents and full-dose classic cytotoxic chemotherapy will become more effective as we learn to use these compounds in a less systemically toxic manner and as radiation fields become more defined. In addition, increasing numbers of biologic modifiers of normal tissue response are becoming available, and they suggest great promise for decreasing the normal tissue toxicity resulting from both radiation and chemotherapy treatments. Thus, radiation metastectomy for gross metastases, used together with systemic control of micrometastatic disease, may yield improved survival rates. This hypothesis is ready for testing in cancers of the breast, prostate, colon, and in sarcomas. Enlarging the therapeutic window is a major goal that would allow for an increasingly favorable therapeutic gain.

Abstract
The use of radiotherapy in soft-tissue sarcoma continues to evolve. This review focuses on how current management is influenced by the most recent publications in the field. In particular, experience of patients treated without radiotherapy permits guidelines to be established that define a subset of patients who do not need radiotherapy to achieve sarcoma cure with good function. Strategies for radiotherapy delivery are discussed, including the most recent prospective results from a trial of preoperative and postoperative radiotherapy, with particular emphasis on randomized data. Also, the definitions for adequacy of surgical excision and the ability to achieve high rates of local control when margins are minimally positive are integrated into a planned approach. The difficult problem of retroperitoneal sarcoma is discussed, as are chemoradiotherapy protocols that may enhance local and systemic outcome. Finally, the potential for image-guided radiotherapy, enhanced targeting, and better radiotherapy delivery in the contemporary era is addressed.

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.
