Abstract
Liposarcomas are the most common retroperitoneal soft tissue tumors. We here in report a case of giant retroperitoneal sarcoma which weighed 24 kgs. Renal autotransplant of right kidney was done for organ preservation. The patient has done well after a follow up of 63 months. Complete surgical resection with organ preservation is the goal of treatment in patients with retroperitoneal liposarcomas.

Abstract
Purpose To evaluate the treatment outcome and prognostic factor after postoperative radiotherapy in retroperitoneal sarcoma. Materials and Methods Forty patients were treated with surgical resection and postoperative radiotherapy for retroperitoneal sarcoma from August 1990 to August 2008. Treatment volume was judged by the location of initial tumor and surgical field, and 45-50 Gy of radiation was basically delivered and additional dose was considered to the high-risk area. Results The median follow-up period was 41.4 months (range, 3.9 to 140.6 months). The 5-year overall survival (OS) was 51.8% and disease free survival was 31.5%. The 5-year locoregional recurrence free survival was 61.9% and distant metastasis free survival was 50.6%. In univariate analysis, histologic type (p = 0.006) was the strongest prognostic factor for the OS and histologic grade (p = 0.044) or resection margin (p = 0.032) had also effect on the OS. Histologic type (p = 0.004) was unique significant prognostic factor for the actuarial local control. Conclusion Retroperitoneal sarcoma still remains as a poor prognostic disease despite the combined modality treatment including surgery and postoperative radiotherapy. Selective dose-escalation of radiotherapy or combination of effective chemotherapeutic agent must be considered to improve the treatment result especially for the histopathologic type showing poor prognosis.

Abstract
BACKGROUND Retroperitoneal tumors are often massive and can involve adjacent organs and/or vital structures, making them difficult to resect. Completeness of resection is within the surgeon's control and critical for long-term survival, particularly for malignant disease. Few studies directly address strategies for complete and safe resection of challenging retroperitoneal tumors. METHODS Fifty-six patients representing 63 cases of primary or recurrent retroperitoneal tumor resection between 2004-2009 were identified and a retrospective chart review was performed. Rates of complete resection, use of adjunct procedures, and perioperative complications were recorded. RESULTS In 95% of cases, complete resection was achieved. Fifty-eight percent of these cases required en bloc multi-organ resection, and 8% required major vascular resection. Complete resection rates were higher for primary versus recurrent disease. Adjunct procedures (ureteral stents, femoral nerve monitoring, posterior laminotomy, etc.) were used in 54% of cases. Major postoperative complications occurred in 16% of cases, and one patient died (2% mortality). CONCLUSIONS Complete resection of challenging retroperitoneal tumors is feasible and can be done safely with important pre- and intraoperative considerations in mind.

Abstract
Large retroperitoneal liposarcomas represent a unique situation and require a more aggressive surgical approach, including multiple resections for recurrences. We report a series of 5 cases of large retroperitoneal liposarcoma managed aggressively with surgical resection. All cases presented with lump and abdominal pain and diagnosis was established by Ultrasonography and CT scan. Post-operative course was uneventful and a median follow up of 3 years, all patients were free from recurrence.

Abstract
The authors undertook a systematic review to designate the role that radiotherapy (RT) might play in the treatment of retroperitoneal sarcomas. Correlating with recent literature, the objective of this review was to evaluate whether there was enough evidence for the authors to develop an institutional treatment protocol concerning the use of RT in the treatment of retroperitoneal sarcoma. Furthermore, this was a call for surgeons to talk to radiation oncologists before performing surgery. The 2 objectives of this review were: 1) to determine the benefit of RT in terms of local control and/or survival in the treatment of retroperitoneal sarcomas and 2) to discover the optimal timing of RT in the treatment sequence. A computerized literature search was performed in the PubMed database, the Cochrane Library database, and reference lists; and journals also were searched by hand to identify all retrospective and prospective reports published since 1998 relating to RT treatment of adult retroperitoneal sarcoma. Mainly, analyses were sought that were based on a 5-year local control rate (LCR), 5-year disease-free survival, and 5-year overall survival (OS). If only 2 years follow-up were available, then the authors also noted this outcome. Toxicity data were collected and analyzed separately. The synthesis of the literature was based on 9 prospectively nonrandomized studies and 10 retrospective studies that, together, reviewed a total of 1426 patients. The 5-year LCR varied from 27% to 62%, and the results from other reports fell in between those values. The 5-year OS rate ranged from 12% to 90%, and complete resection and tumor grade were the most important prognostic factors in most studies. This review resulted in 7 recommendations concerning the use of RT in the treatment of retroperitoneal sarcoma. The authors concluded that there is good evidence from multiple single-institutions studies that RT improves the LCR in patients with retroperitoneal sarcoma. Until now, there has not been a translation of this approach into survival benefit. The current results indicated that preoperative external-beam RT followed by radical surgery seems to be the preferred sequence, and adding intraoperative RT is a safe procedure for dose escalation in the upper abdomen.

Abstract
The primary modality of treatment for a localized soft tissue sarcoma is surgical resection. Adjuvant or neoadjuvant radiation helps reduce the rate of local recurrence. The rate of limb preserving resection is 94% in our series. Local recurrence can be re-excised in 95% of the patients, with limb preservation in 90%. Retroperitoneal sarcomas present difficulties in resection but with optimal techniques the complete resectability rate approaches 95% with 5- and 10-year survivals rates of 65% and 56%.

Abstract
Purpose The primary aim of this work was to analyze feasibility of combined treatment of retroperitoneal sarcomas (RS): surgery (S) and intraoperative brachytherapy (IOBRT). The secondary aim was to analyze results and complications after this treatment. Material and methods 84 patients with retroperitoneal sarcomas were qualified for combined treatment (S and IOBRT) between June 1998 and September 2006. 65 of the patients (77.4%) had local recurrences. Sarcomas with intermediate and high grade of histological malignancy (G2, G3 – 76.2%) were the most frequent within the all surgically treated patients. Resection ability (R0/R1) in analyzed group of patients was estimated as 85% (74 cases). After intraoperative evaluation, 57 (67.8%) patients were qualified for IOBRT. Since 2000, in 34 patients (60%) an adjuvant postoperative external beam radiation therapy (EBRT) in dose of 50 Gy was applied. Median follow-up of the surviving patients was 40 months. Results On the basis of the univariate analysis, relevant aspects negatively influencing overall survival rate within the RS group treated with IOBRT were as follows: surgery of sarcoma recurrence (p = 0.002), higher grade of histological malignancy (p = 0.05), histological type different than liposarcoma (p = 0.05) as well as no adjuvant EBRT (p = 0.05). On the basis of multivariate analysis one can ascertain that relevant factors negatively influencing LRFS in RS patients treated with IOBRT were: surgery due to recurrence of sarcoma (p = 0.008) and lack of EBRT (p = 0.01). Conclusions Combined treatment (surgery and brachytherapy) was possible to be carried out on 68% of RS patients. The overall number of complications was quite high, however acceptable, taking into consideration the application of extensive, multi-organ treatments in case of sarcoma recurrences in this localization. The results suggest that the method of treatment will improve the final outcome when most of patients will be qualified for treatment of primary sarcomas in experienced centre.

Abstract
OBJECTIVE To identify predictors of survival after resection of retroperitoneal sarcoma (RPS) and to evaluate the performance of the American Joint Committee on Cancer (AJCC) staging system for RPS. SUMMARY BACKGROUND DATA Previous studies of survival after RPS resection are restricted to at most several institutions, yet the current AJCC staging system for RPS is based entirely on these relatively small studies. METHODS Patients undergoing resection of primary RPS from 1988 to 2005 were identified from the Surveillance, Epidemiology, and End Results (SEER) database. Cox proportional hazards models were used to analyze survival and evaluate AJCC staging. RESULTS In 1365 patient undergoing resection of primary RPS, the most prevalent histologies were liposarcoma (50%), leiomyosarcoma (26%), and malignant fibrous histiocytoma (11%). Median, 5-year, and 10-year survival after resection were 55 months, 47%, and 27%. Histological subtype (P < 0.001), histological grade (grade 3-4 vs. grade 1; HR, 2.42; P < 0.001), and tumor invasion of adjacent structures (HR, 1.37; P < 0.001) were associated with survival on multivariable analysis. However, tumor size had no prognostic value. Consequently, the AJCC T classification system demonstrated poor discriminatory ability (c = 0.50). The AJCC stage grouping system demonstrated moderate discriminatory ability (c = 0.66) but performed no better than a much simpler system that omits information on tumor size and lymph node metastasis (c = 0.67). CONCLUSIONS Indicators of tumor aggressiveness (histological grade and invasion of adjacent structures) as well as histological subtype predict survival after RPS resection. Tumor size, however, does not impact survival. The AJCC staging system for RPS is in need of revision.

Abstract
Retroperitoneal soft-tissue sarcomas are complex, heterogeneous cancers requiring expert multidisciplinary care. They can occur anywhere in the retroperitoneal abdominal or pelvic space. Usually large at presentation they present particular challenges for both local treatment and systemic control. The most common adult subtypes are liposarcomas and leiomyosarcomas, followed by pleomorphic sarcoma/malignant fibros histiocytoma (an entity not always easily distinguishable from dedifferentiated liposarcoma). A variety of additional histotypes may also be observed, but are uncommon in the retroperitoneum, either because of intrinsic rarity or because they are usually found in other anatomic sites. The underlying biology varies according to the different histotypes. Pediatric subtypes mainly comprise extraskeletal Ewing sarcoma/pPNET and alveolar rhabdomyosarcoma. Surgery is critical for controlling these tumors and requires an aggressive approach. It may also provide useful palliation for patients with advanced slow-growing disease. Radiotherapy has acquired a definite position in attempting to reduce relapse, although prospective trials of adjuvant or neoadjuvant radiotherapy are needed. Chemotherapy has a limited role in the adjuvant setting for most forms of retroperitoneal sarcoma (excluding pediatric subtypes), but has an increasing role in advanced disease. Novel targeted therapeutic agents that target specific amplification or translocation products offer promise for subsets of these diseases.

Abstract
Introduction. Retroperitoneal sarcomas are uncommon large malignant tumors. Methods. Forty-one consecutive patients with localized retroperitoneal sarcoma were retrospectively studied.
Results. Median age was 58 years (range 20–91 years). Median tumor size was 17.5 cm (range 4–41 cm). Only 2 tumors were <5 cm. Most were liposarcoma (44%) and high-grade (59%). 59% were stage 3 and the rest was stage 1. Median followup was 10 months (range 1–106 months). Thirty-eight patients had an initial complete resection; 15 (37%) developed recurrent sarcoma and 12 (80%) had a second complete resection. Patients with an initial complete resection had a 5-year survival of 46%. For all patients, tumor grade affected overall survival (P = .006). Complete surgical resection improved overall survival for high-grade tumors (P = .03). Conclusions. Tumor grade/stage and complete surgical resection for high-grade tumors are important prognostic variables. Radiation therapy or chemotherapy had no significant impact on overall or recurrence-free survival. Complete surgical resection is the treatment of choice for patients with initial and locally recurrent retroperitoneal sarcoma.

Abstract
Retroperitoneal sarcomas (RPS) represent approximately 15% of all soft tissue sarcomas (STS). Clinical and prognostic features as well as oncologic outcomes are well known in this group of patients. Post-operative margin status specifically, is a major predictor of local and distant recurrence and survival. The purpose of this review is to define complete resection as it applies to RPS and evaluate its effect on future outcomes in these patients.

Abstract
Soft tissue sarcomas (STS) in the retroperitoneum are usually diagnosed at the late stages. Surgery is the mainstay of treatment. The technique of resection is standardized. After dissection of the retroperitoneal blood vessel, a retroperitoneal plane of dissection adjacent to the spinal foramina is established in between the layers of the abdominal wall. Complete resection with tumor-free resection margins is the primary goal in retroperitoneal sarcoma surgery. Preoperative assessment of pathoanatomical growth patterns with respect to retroperitoneal vascular structures--as well as to visceral and retroperitoneal organs--influences surgical strategies and thus the surgical outcome. Blood vessel replacement and a multivisceral en bloc approach improve the quality of resection. Blood vessel involvement is stratified in type I (arterial and venous involvement), type II (arterial involvement), type III(venous involvement), and type IV (no vascular involvement). Adjuvant and neoadjuvant treatment options (chemotherapy, targeted therapy, and radiation therapy) are currently being investigated. A prospective randomized phase III trial has shown a positive effect of neoadjuvant chemotherapy combined with regional hyperthermia in disease-free survival, response rate, and local control. Subsets of liposarcomas (myxoid and round cell type) are selectively responsive to novel drugs, such as trabectedin, a DNA-binding agent. Radiotherapy is applied in higher-grade locally advanced retroperitoneal STS. The optimal technique of delivering radiotherapy remains to be determined. The restricted number of patients with retroperitoneal STS and unsatisfying results in local tumor control and long-term survival indicate the need for multi-institutional cooperative studies. An international effort is required to improve the evidence level on multimodal treatment algorithms.

Abstract
Mixed-type liposarcoma is a rare soft tissue tumor. This report describes a 50-year-old man with retroperitoneal mixed-type liposarcoma that consisted of four pathologically different components. Preoperative CT and MRI showed a giant retroperitoneal mass composed of several nodules with various attenuation and signal intensity. At laparotomy, the tumor appeared to be composed of four components. Pathologic examination revealed that each component was of a histologically different subtype. Mixed-type liposarcoma containing four different subtypes is extremely rare. Its clinical and pathologic features are briefly reviewed.

Abstract
STS are a heterogeneous group of malignant tumors that pose significant management challenges. The cornerstone of therapy for patients who have primary STS remains margin-negative resection. Adjuvant radiotherapy has been shown to reduce the risk of recurrence for extremity and trunk STS, although its role for retroperitoneal STS remains to be defined. Neoadjuvant radiotherapy has some theoretic advantages to postoperative radiation, but its exact role has yet to be determined. Chemotherapy is usually reserved for chemotherapy-sensitive histologic subtypes and for patients who have metastatic STS.

Abstract
Background Retroperitoneal schwannomas are rare, usually benign tumors that originate in the neural sheath and account for only a small percentage of retroperitoneal tumors. The aim of this clinical study is to present our experience in managing retroperitoneal schwannomas with a review of the current literature and to point out the surgical technical difficulties we faced, due to the tumor's strange behavior that eroded the vertebra in two cases without causing malignant invasion. Methods We reviewed the medical files of 69 patients treated in our department for retroperitoneal tumors from January 1991 until December 2006. Five patients had retroperitoneal schwannomas according to pathology report. Results There were two male and three female patients, with a mean age of 56 years (range 44–67 years). All patients were asymptomatic and none suffered from von Recklinghausen disease. Imaging workup included ultrasonography, computed tomography and magnetic resonance imaging. One patient, after having a non-diagnostic computed tomography fine needle aspiration (CT-FNA), underwent exploratory laparotomy and incisional biopsy that established the diagnosis of schwannoma. After complete excision of the tumors, postoperative course was uneventful in all patients. Tumors' maximum diameter was 12.7 cm (range 7–20 cm). No recurrences were detected during the follow up period (6–75 months). Conclusion Preoperative establishment of diagnosis is difficult in case of retroperitoneal schwannomas, however close relationship of retroperitoneal tumors with adjacent neural structures in imaging studies should raise a suspicion. Complete surgical resection is the treatment of choice. Histology and Immunohistochemistry confirms the diagnosis.

Abstract
Purpose:To discuss a case of ovarian fibromatosis/massive ovarian oedema, intra-abdominal fibromatosis, sclerosing
peritonitis and Meig's syndrome. To review the reported therapeutic options. Patients: Case report of a 27-year-old female with the combined pathology of ovarian fibromatosis/massive ovarian oedema,
intra-abdominal fibromatosis, sclerosing peritonitis and Meig's syndrome. Methods: This patient was treated with supportive care and cytotoxic chemotherapy. Results: Despite the benign nature of the ovarian pathology, this patient presented with life-threatening complications.
Response to treatment was probably multi-factorial combining the effects of cytotoxics, use of steroids and good supportive
care. She remains in complete remission 4 years post completion of chemotherapy. Conclusion: There are reports in the literature of ovarian fibromatosis/massive ovarian oedema, luteinised thecomas, intraabdominal
fibromatosis and Meig's syndrome occurring together in a variety of combinations. Treatment has been described
with radiotherapy, cytotoxic and non-cytotoxic chemotherapy regimens. This case provides a link between ovarian
fibromatosis/massive ovarian oedema, intra-abdominal fibromatosis, sclerosing peritonitis and Meig's syndrome not
previously described.

Abstract
The case presented here illustrates a 75 year old female patient who underwent surgical resection of a right adrenal mass of uncertain nature. The final histological diagnosis was consistent with leiomyosarcoma arising from the adrenal anatomic site. Primary leiomyosarcoma of the adrenal gland is a very rare malignant mesenchymal neoplasm: to our knowledge, this is only the twelfth case reported in literature. We describe the clinical course and a brief review of clinical and histological features, biologic behaviour, diagnostic approaches and therapeutic strategies.

Abstract
Retroperitoneal soft tissue sarcoma (RPS) is extremely rare in pregnancy, so there has been little experience in dialing with this condition. We report our experience of a pregnant patient with a retroperitoneal soft tissue sarcoma, which was treated by complete surgical resection at 17 weeks gestation. After regular follow-up, the patient admitted to our hospital in labor, in the 38th gestational week and vaginally delivered a male fetus weighing 3,200 g with Apgar score of 8 and 10 at 1 and 5 min respectively. Adjuvant radiotherapy and chemotherapy is controversial in RPS and due to postoperative continuation of pregnancy in our case, the adjuvant therapy was not practiced. The patient had an uneventful recovery, and no recurrence was detected for 20 months in the follow-up period.

Abstract
PURPOSE To determine the long-term outcomes after multimodality treatment of retroperitoneal, pelvic, and deep truncal sarcomas and to identify the factors associated with local control (LC), distant metastasis (DM), and overall survival (OS). METHODS AND MATERIALS A total of 85 patients with retroperitoneal, pelvic, and deep truncal sarcomas were treated with radiotherapy (RT) between 1987 and 2005. A retrospective analysis of LC, DM, and OS was conducted using log-rank and Cox regression statistical methods. RESULTS The 2- and 5-year LC, DM, and OS rates were 66% and 51%, 38% and 58%, and 70% and 34%, respectively. Negative surgical margins and a higher radiation dose were associated with greater LC rates on both univariate and multivariate analyses, and female gender was significantly associated with greater LC on multivariate analysis only. None of the analyzed risk factors was significantly associated with DM, although patients with high-grade tumors showed a trend toward an increased risk of DM. Gross residual disease after resection and high tumor grade were associated with worse OS rates on univariate and multivariate analyses, and male gender was significantly associated with worse OS on multivariate analysis only. A time-dependent analysis of LC in relation to DM demonstrated that patients with local failure had a hazard ratio of 19.7 for DM compared with patients without local failure (p < 0.0001). Of the 85 patients, 5 and 8, respectively, had clinically significant acute and late toxicity. CONCLUSION The results of this study emphasize the importance of LC in patients with retroperitoneal sarcoma. Radiation dose escalation or radiosensitization strategies to enhance LC are warranted.

Abstract
Sarcomas represent a rare, heterogeneous group of malignant tumors that arise from the mesenchymal tissues of the body. Although infrequently encountered, these tumors generate vigorous academic interest and an ever-expanding volume of medical literature. Chemotherapy is widely regarded as ineffective because of the often-large tumor burden and lack of good therapeutic drugs. Radiation therapy is often difficult to administer because of locoregional toxicity. Fortunately, targeted immunologic therapies have shown promise in some specific gastrointestinal mesenchymal tumors. To date, sarcoma remains a malignancy best treated operatively. Given the wide heterogeneity and biology of these tumors and the amount of new data available, a review of the current literature is warranted. The first installment of this review series1 dealt with extremity and trunk soft tissue sarcomas; this one will focus on retroperitoneal and visceral sarcomas and the management challenges they pose.

Abstract
BACKGROUND Treatment of peritoneal recurrence following surgical resection of intra-abdominal sarcomas presents a significant challenge to clinicians. Historically, treatment with systemic chemotherapy has been ineffective and surgical resection alone has not been durable. We prospectively evaluated the feasibility of cytoreductive surgery followed by hyperthermic intraperitoneal chemotherapy (HIPEC) with cisplatin (CDDP) alone or in combination with mitoxantrone (MITOX) for the treatment of sarcomatosis. METHODS Two phase I trials of HIPEC were conducted (1998-2003). Eligible patients with evidence of sarcomatosis underwent cytoreductive surgery followed by HIPEC. In the first trial, CDDP dosing was established as 90 mg/m2 with a perfusate time of 90 minutes and temperature of 41 degrees C. In the second trial, MITOX (20 mg/m2) was instilled following perfusion with CDDP. Toxicity, efficacy, and quality of life (QOL) were evaluated. RESULTS A total of 28 patients were enrolled in the two trials. We noted a higher overall toxicity score and complication rate with combination CDDP/MITOX versus CDDP alone and shorter overall survival duration (5.5 months vs 16.9 months, respectively). In addition, local recurrence rates were similar in both groups (CDDP 79% vs CDDP/MITOX 68%). As expected, QOL scores at 6-8 weeks following HIPEC were 15-25% lower than the baseline scores; however, they returned to baseline at 3-6 months. CONCLUSIONS Although the HIPEC technique is feasible for patients with sarcomatosis, it is associated with significant toxicity and limited clinical benefit. Combination CDDP/MITOX failed to demonstrate any benefit over CDDP alone; moreover, there was an increase in toxicity.

Abstract
AIMS In order to achieve complete resection in the surgical management of retroperitoneal tumors, it is crucial to know the tumor's anatomical location relative to neighboring organs. METHODS Forty-nine patients with primary malignant retroperitoneal tumors were divided by tumor location into two groups [upper abdomen (group 1) or lower abdomen (group 2)], and clinicopathological features, tumor recurrence, and patient survival were assessed. RESULTS No significant differences in preoperative clinical characteristics existed between two groups, and liposarcoma was the most frequently observed tumor type. The difference in the rates of complete resection between the two groups was not statistically significant (75.9% for group 1 and 85% for group 2). En-bloc combined resection was performed in 52% and 30% of patients in groups 1 and 2, respectively. The local recurrence rate in group 2 (31.3%) was higher than that in group 1 (9.5%), despite the fact that the differences in rates of complete resection and distant recurrence rates (14.3% in group 1 and 12.5% in group 2) between the two groups were not statistically significant. The overall 5-year survival rates were 67.9% for group 1 and 43.2% for group 2 (p=0.038). The 5-year survival rate of patients with tumors smaller than 10 cm was 78.4%, while that of patients with tumors larger than 10 cm was 38.1% (p=0.017). The 5-year survival rate after complete excision was 61%, whereas that after incomplete resection or biopsy only was 40.0% (p<0.0001). CONCLUSIONS An upper abdominal tumor location is a positive prognostic factor even if small tumor size (<10 cm) and complete resection of the tumor are still more important factors to improve outcome in patients with malignant primary retroperitoneal tumors. Because complete resection was shown to be the most important prognostic factor, an aggressive and careful surgical approach is recommended for the treatment of such tumors.

Abstract
PURPOSE To evaluate the clinical outcomes of patients with localized retroperitoneal soft tissue sarcoma (STS) treated with complete surgical resection and radiation. METHODS AND MATERIALS The medical records of 83 patients were reviewed retrospectively. Sixty patients presented with primary disease and the remaining 23 had recurrence after previous surgical resection. RESULTS With a median follow-up of 47 months, the actuarial overall disease-specific survival (DSS), distant metastasis-free survival, and local control (LC) rates were 44%, 67%, and 40%, respectively. Of the 38 patients dying of disease, local disease progression was the sole site of recurrence for 16 patients and was a component of progression for another 11 patients. Multivariate analysis indicated that histologic grade was associated with the 5-year rates of DSS (low-grade, 92%; intermediate-grade, 51%; and high-grade, 41%, p = 0.006). Multivariate analysis also indicated an inferior 5-year LC rate for patients presenting with recurrent disease, positive or uncertain resection margins, and age greater than 65 years. The data did not suggest an improved local control with higher doses of external-beam radiation (EBRT) or with the specific use of intraoperative radiotherapy (IORT). Radiation-related complications (10% at 5 years) developed in 5 patients; all had received their EBRT postoperatively. CONCLUSIONS Although preoperative radiation therapy and aggressive surgical resection is well tolerated in patients, local disease progression continues to be a significant component of disease death. In this small cohort of patients, the use of higher doses of EBRT or IORT did not result in clinically apparent improvements in outcomes.

Abstract
PURPOSE The study was conducted to evaluate the clinical results of resection for retroperitoneal soft tissue sarcoma (STS) with vascular involvement. METHODS The study group consisted of consecutive patients (mean age, 52 years) who underwent surgery for retroperitoneal STS with vascular involvement. The procedures were performed between 1988 and 2004. Vessel involvement by STS was classified as type I, artery and vein; type II, only artery; type III, only vein; and type IV, neither artery nor vein (excluded from the analysis). Patient data were prospectively gathered in a computerized database and retrospectively analyzed. RESULTS Of 141 patients with retroperitoneal STS, 25 (17.7%) underwent surgery for tumors with vascular involvement. The most common vascular involvement pattern was vein only (type III) at 64%. Arterial and vein (type I) and arterial only (type II) involvement were observed in 16% and 20% of the cases, respectively. STS originating from the vessel wall (primary vessel involvement) was seen in eight patients, and 17 patients had secondary vascular involvement. Resection and vascular repair were done in 22 patients (no vascular repair in three patients due to ligation of the external iliac vein in one patient, and debulking procedures in two). All patients with arterial involvement (type I and II) had arterial reconstruction consisting of aortic replacement (Dacron, n = 3; and expanded polytetrafluoroethylene [ePTFE], n = 2), iliac repair (Dacron, n = 3), and truncal reimplantation (n = 1). The inferior vena cava (6 ePTFE tube grafts, 3 ePTFE patches, 2 venoplasties), iliac vein (1 ePTFE bypass, 1 Dacron bypass, 1 venous patch), and superior mesenteric vein (1 anastomosis, 1 Dacron bypass) were restored in 80% of the patients (n = 16) with either arterial and venous or only venous involvement (type I and type III setting). Morbidity was 36% (hemorrhage, others), and mortality was 4%. At a median follow-up of 19.3 months (interquartile range, 12.8 to 49.9 months) the arterial patency rate was 88.9%, and the venous patency rate was 93.8% (primary and secondary). Thrombosis developed in one arterial and venous (type I) iliac reconstruction due to a perforated sigmoid diverticulitis 12 months after surgery. The local control rate was 82.4%. The 2-year and 5-year survival rates were 90% and 66.7% after complete resection with tumor-free resection margins (n = 10 patients, median survival not reached at latest follow-up). The median survival was 21 months in patients with complete resection but positive resection margins (n = 7) and 8 months in patients with incomplete tumor clearance (n = 8, persistent local disease or metastasis). CONCLUSIONS Patency rates and an acceptable surgical risk underline the value of en bloc resection of retroperitoneal STS together with involvement of blood vessels. The oncologic outcome is positive, especially after complete resection with tumor-free resection margins. A classification of vascular involvement can be used to plan resection and vascular replacement as well as to compare results among reports in a standardized fashion.

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 The reported data on surgery plus radiotherapy for retroperitoneal soft tissue sarcomas (RPS) have been mostly from retrospective studies. We evaluated the long-term outcome of patients with operable RPS who were treated with protocol-based preoperative radiotherapy followed by complete surgical resection. METHODS Data from two prospective trials that included preoperative radiotherapy and surgery for patients with radiographically resectable RPS were combined to define long-term relapse rates and survival. RESULTS Seventy-two patients with intermediate- or high-grade RPS were treated with preoperative radiotherapy (median dose, 45 Gy; range, 18.0-50.4 Gy). Fifty-four patients (75%) had primary RPS, whereas 18 (25%) had recurrent disease. The median tumor size was 15.5 cm. Sixty-four patients completed the planned preoperative radiotherapy; 57 (89%) underwent laparotomy with curative intent, and 54 (95%) had a macroscopically complete (R0 or R1) resection. With a median follow-up of 40.3 months, 28 patients (52%) who received preoperative radiotherapy and underwent a macroscopically complete resection had recurrences. For the 54 patients who underwent R0 or R1 resection after preoperative radiotherapy, the 5-year local recurrence-free, disease-free, and overall survival rates were 60%, 46%, and 61%, respectively. The median overall survival has not been reached (>60 months). CONCLUSIONS Patients with intermediate- or high-grade RPS treated with preoperative radiotherapy plus complete resection had a median survival >60 months. This compares favorably to historical data for similar patients treated with surgery alone.

Abstract
BACKGROUND The purpose of this study was to analyze the results of treatment of retroperitoneal soft tissue sarcomas (RSTS) by surgery combined with intraoperative brachytherapy (IOBRT). METHODS Seventy adult patients with RSTS were considered for combined treatment (surgery plus IOBRT) between June 1998 and February 2004. There were 64 (91%) recurrent tumors, and 93% of tumors exceeded 5 cm. IOBRT was performed with high-dose-rate Gammamed 12 with iridium 192 (IOBRT time range, 20-87 minutes; median, 56 minutes). RESULTS After intraoperative re-evaluation, 24 patients (34%) were found to be ineligible for IOBRT because of multiple intraperitoneal recurrences, macroscopically nonradical resection, poor general condition, and technical aspects. Thirty-seven patients underwent IOBRT immediately after surgery during the same general anesthesia procedure. Nine patients underwent delayed IOBRT within 1 to 3 days after the primary operation. Ten (21.5%) of 46 patients underwent reoperation because of surgical complications. One patient died in the postoperative period. After IOBRT, 24 patients (52%) underwent adjuvant external beam radiotherapy (EBRT) to a total dose of 50 Gy. Over a median follow-up time of 20 months, the estimated 5-year overall survival and local recurrence-free survival rates in IOBRT patients were 55% and 51%, respectively. Application of adjuvant EBRT showed a favorable local control rate. CONCLUSIONS The scheduled combined treatment (surgery plus IOBRT) was possible to perform in 66% of RSTS cases that received surgical treatment. The complication rate was high, but we consider it acceptable because of the necessity for extensive aggressive surgical treatment in regionally advanced RSTS. EBRT seems to be an indispensable part of treatment that provides better local control.

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
INTRODUCTION Retroperitoneal Liposarcoma is a rare and primary malignancy developed from mesenchymal tissue. It's generally unique and shows an only one histologic component. We report a case of multicentric and synchronous liposarcoma (intraperitoneal and retroperitoneal) and with different histologic types. EXEGESES A 53-year old man presented with abdominal pain, increased abdominal girth and weight loss. Physical examination revealed two abdominal masses. Computed tomography scan showed a very large retroperitoneal mass displacing the left kidney, digestive loops and vessels. The patient underwent surgery. One enormous mass of the left renal lodge measuring 50 cm, a retroduodenal mass measuring 15 cm and a nodule of the coecum were removed. Histological examination of the mass of the left renal lodge revealed mixed type liposarcoma (dedifferentiated and myxoid). Histological examination of the retroduodenal mass and of the nodule of the coecum revealed well-differentiated liposarcoma. CONCLUSION Pathological, therapeutic and prognostic aspects of abdominal liposarcoma will be reviewed in this article.

Abstract
BACKGROUND AND OBJECTIVES Retroperitoneal sarcomas are rare malignant tumors with an aggressive course of disease and high local recurrence rate. Local disease is the main cause of death. A retrospective study was undertaken to evaluate the results of aggressive surgical treatment in a series of patients of primary and recurrent retroperitoneal sarcomas. PATIENTS AND METHODS From 1975 to 2000, 155 patients with retroperitoneal tumors were operated on at the Institute of Oncology, Ljubljana. Patients with fibromatosis and children less than 16 years were excluded from further calculation. Out of the rest 139 patients, 102 patients had localized retroperitoneal sarcoma, and 37 patients had retroperitoneal sarcoma with distant metastases Leiomyosarcoma was the most common type of histology, followed by liposarcoma and schwannoma. Their referral status was as follow: 56 had primary sarcoma, 20 residual sarcoma after operation elsewhere and 26 already recurrent sarcoma. Our treatment approach was aggressive. We removed surgically primary tumor, recurrent sarcoma and metastases, whenever possible. To this end, we performed, 235 operations for retroperitoneal sarcomas on 139 patients (up to 8 operations on 1 patient). RESULTS Complete resection was done in 97 of 102 patients with localized sarcoma (resectability rate 95%); in 55 patients, R0 resection was made, in 42 patients, R1 resection, in 3 patients, debulking procedure, and in 2 patients biopsy alone. In 118, patients at least one organ was resected completely or partially en bloc with tumor. The 5-, 10-, and 15-year survivals of patients with localized sarcoma were 52%, 36%, and 22%, respectively. The 5-year survival of patients with metastases was 12% (P = 0.0002), the 5- and 10-year survival rates of patients with R0 resection were 75% and 64%, respectively, and of those with R1 resection, 25% and 8%, respectively (0 < 0.00001). High tumor grade was associated with poor survival. The 5-year local recurrence rate of patients with primary sarcoma and of those with locally recurrent sarcoma was 37% and 71%, respectively (P = 0.04). After the first local recurrence, the 5- and 10-year survival rates were 42% and 26%, after the second local recurrence 45% and 22%, after the third local recurrence 43% and 11%, and after the fourth local recurrence 51% and 17%, respectively. CONCLUSION Complete surgical resection without microscopic residuum and contamination is likely to offer the best chances for long-term survival. Until there are no other treatment modalities, aggressive surgery for recurrent sarcoma is recommended.

Abstract
Liposarcomas are the most prevalent soft tissue sarcomas in adults. Low-grade liposarcomas are the most frequent and least aggressive and are noted as having a low risk of metastasis. We present a case of low-grade myxoid liposarcoma that metastasized to the small bowel resulting in intussusception. This case involves a 44-year-old woman with a recurrent retroperitoneal liposarcoma. Approximately 30 months after initial diagnosis, the patient was found to have a solitary metastasis to the small bowel that presented as a jejunal intussusception. Interestingly, there was no indication of a round cell component in either the metastasis or recurrent tumor, although the original tumor did contain a small round cell component. This is the first report in the English literature of liposarcoma metastasizing to the small bowel. We suggest that atypical presentations of liposarcoma metastases should always be considered in the management of patients with a history of liposarcoma.

Abstract
Stage III carcinoma of the cervix is treated usually, and often effectively, with the combination of radiation and chemotherapy. For tumors locally recurring, without evidence of distant lymphatic or hematogenous spread, the option of pelvic exenteration rises. The described surgical technique derives from soft tissue sarcoma pelvic surgery. It is a lower midline incision extending transversely at its lower end ("reverse T"), which improves the exposure and hence resectability of some of these tumors.

Abstract
Retroperitoneal fatty tumours are uncommon occurrences in current urologic practice, the differentials being lipomas, liposarcomas and extra-renal angiomyolipomas (AML). We report an unusual case of a 48-year-old Chinese female who presented with a 6.2 kg giant mixed-type liposarcoma in the left perinephric space, invading into the renal cortex and parenchyma. Extirpative surgery with left radical nephrectomy was performed, and histology confirmed liposarcoma with both myxoid and well-differentiated elements. The patient remains well and disease-free at 6-month follow-up. We review the literature on the diagnosis and management of these perinephric lipomatous lesions. We also discuss the diagnostic dilemma in differentiating such malignancies from benign angiomyolipomas in the perinephric area on conventional radiological imaging, and its direct implications with respect to extent of surgery and renal preservation.

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
Understanding prognostic variables is important for counseling patients, selecting patients for adjuvant therapy, stratifying patients for inclusion in clinical trials, and setting goals for patient treatment. Prognostic variables in soft tissue sarcoma have been defined for local recurrence, distant recurrence, and disease-specific and overall survival. Significant prognostic variables are site-dependent and time-dependent. A recently created nomogram that accounts for tumor size, grade, histology, and depth and patient age is a tool that can be used to predict 12-year sarcoma-specific survival at diagnosis. Emerging areas in predicting outcome of patients with soft tissue sarcoma include response to neoadjuvant chemotherapy and molecular markers.
