Sharma J, Deo SVS, Kumar S, Bhoriwal S, Kar M, Barwad AW, Thulkar S, Bakhshi S, Sharma DN. Demographic and clinical profile of 1106 adult soft tissue sarcoma patients: A single institutional prospective database experience from India. Asia Pac J Clin Oncol 2024; 20:386-394. [PMID: 38383968 DOI: 10.1111/ajco.14050] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2023] [Revised: 01/28/2024] [Accepted: 02/02/2024] [Indexed: 02/23/2024]
Abstract
BACKGROUND Adult soft tissue sarcomas (STS) are rare and diverse. Current management is based on limited literature from the West. Therefore, data from different geographical regions is required, including the low-middle-income countries. This is our experience managing adult sarcomas in the tertiary cancer center of North India. MATERIALS AND METHODS This is a retrospective analysis of the structured sarcoma database of patients treated in the surgical oncology department between 1992 and 2020. The descriptive analysis includes demography, site distribution, diagnosis, histopathology variations, prior surgical interventions, and stage. RESULTS A total of 1106 soft tissue sarcoma patients were treated in three decades. Age distribution was 13%, 43%, 31%, and 11% in <20, 21-40, and 41-60 and >60 years, respectively. The male-to-female ratio was 1.73. The anatomical distribution was 17%, 42%, 23%, 7%, 7%, and 3% in upper extremity, lower extremity, trunk, retroperitoneum, head and neck, and viscera, respectively. Overall, 49% of patients had undergone prior suboptimal surgeries at community hospitals. Common histology subtypes were synovial sarcoma (18%), undifferentiated pleomorphic sarcoma (UPS) (13%), dermatofibrosarcoma protuberans (12%), and liposarcoma (9%). A pathological discordance of 13% was identified between the initial and the final histologies. Overall, 61% of tumors were high-grade. Memorial Sloan Kettering Stages II and III were present in 33% and 35% of patients, respectively. CONCLUSIONS This is one of the largest single institutional experiences of STS from the Asian population. Mostly young adults were affected with male preponderance. The lower extremity and trunk were common subsites. Frequent histologies were synovial sarcoma and UPS. A high rate of suboptimal surgical intervention at the community level and pathological discordance was noted. This study highlights the need to establish prospective structured databases for capturing quality information related to rare malignancies and providing insights for future research.

Evaluation of AJCC staging system and proposal of a novel stage grouping system in retroperitoneal liposarcoma: the Fudan Zhongshan experience. Front Oncol 2024; 14:1373762. [PMID: 38601763 PMCID: PMC11004455 DOI: 10.3389/fonc.2024.1373762] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/20/2024] [Accepted: 03/18/2024] [Indexed: 04/12/2024] Open
Abstract
Background Overall survival (OS) varies significantly among individuals with heterogeneous retroperitoneal liposarcoma (RPLS), even among those with the same clinical stage. Improved staging of RPLS is a critical unmet need, given the disappointing results of external validations of the 8th American Joint Committee on Cancer (AJCC) TNM staging system. Methods The cohort study included 220 consecutive patients who underwent surgical resection for primary RPLS at the largest sarcoma centre of Fudan University in China from September 2009 to August 2021, combined with 277 adult patients with RPLS in the SEER database from 1975 to 2020. Data analysis was performed from December 2021 to December 2022. Patients were retrospectively restaged according to the 8th and 7th editions of the TNM staging system as well as the new TNM (nTNM) staging system. The primary endpoint was overall survival (OS). Comparative analysis of postoperative survival was performed using the Kaplan-Meier method, and differences between subgroups were tested using the log-rank test. The OS prediction nomogram was generated based on baseline variables and tumour characteristics. Harrell's consistency index (C-index), area under the curve (AUC) of receiver operating characteristic curves (ROC), and calibration curves were used to evaluate the performance of the nomogram. Results A total of 497 patients were enrolled in the study, including 282 (56.7%) male patients. The median follow-up was 51 months (interquartile range, IQR, 23-83), and the OS rates at 1, 3, and 5 years were 87.9%, 75.3%, and 64.9%, respectively. According to the staging distribution of the AJCC 7th edition, 6 patients were stage IA (1.2%), 189 patients were stage IB (38%), 12 patients were stage IIA (2.4%), 150 patients were stage IIB (30.1%), 131 patients were stage III (26.3%), and 9 patients were stage IV (1.8%). With the 8th edition staging, this distribution changed: 6 patients (1.2%) were stage IA, 189 patients (38%) were stage IB, 12 patients (2.4%) were stage II, 24 patients (4.8%) were stage IIIA, 257 patients (51.7%) were stage IIIB, and 9 patients (1.8%) were stage IV. 182 patients (36.6%) were reclassified according to the nTNM staging system with the new T stage classification. The C-index and log-rank score improved after implementation of nTNM implementation. The nTNM system was associated with improved identification of high-risk patients compared with the AJCC 7th and 8th TNM. The FNCLCC stage proved to be highly prognostic with significant intergroup differences in OS. The calibration curve shows a high degree of agreement between the actual OS rate and the nomogram estimated OS rate. Conclusion Compared with 8th AJCC TNM, 7th AJCC TNM staging system showed a more homogeneous staging distribution and a slight improvement in the prognostic accuracy of RPLS. The revised T-stage and nTNM systems showed better risk stratification performance. The FNCLCC stage was found to have high prognostic value, further emphasising histological grade is the least negligible prognostic factor in predicting patient survival. The constructed nomogram model enables individualized prognostic analysis and helps to develop risk-adapted therapy for RPLS patients.

Arch Orthop Trauma Surg 2019; 139:443-449. [PMID: 30406818 DOI: 10.1007/s00402-018-3059-x] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/06/2018] [Indexed: 01/25/2023]
Abstract
BACKGROUND AND PURPOSE We reviewed our experience of synovial sarcoma to identify factors predictive of local recurrence and overall survival, the impact of chemotherapy and outcomes after surgical excision alone. MATERIALS AND METHODS 81 patients were treated between 1997 and 2014 of mean age 39 years (8-78). Tumours were in the extremity in 55 (67%). 9 patients presented with metastases and 10 with unresectable disease. Mean follow-up was 3.7 years (SD 3.8). Treatment groups were palliative, surgery only, surgery and radiotherapy, or surgery with chemotherapy (with or without radiotherapy). RESULTS Local recurrence-free survival (LRFS) was 73% at 5 years, and 68% at 10 and 15 years. In multivariate analysis, positive surgical margins were an independent predictor of LRFS. Overall survival (OS) was 50% at 5 years for all patients, and 62% at 5 years for those treated with curative intent. Larger tumour size and non-extremity locations were predictors of poorer OS. Patients who had chemotherapy did not have significantly better OS or LRS than others. INTERPRETATION These results show that where feasible, curative resection should not be delayed for chemotherapy. Treatment with surgery only can be associated with good outcomes in selected patients with smaller extremity tumours; although our series is small.

Abstract
To analyze treatment and survival in a series of resected patients with primary or recurrent retroperitoneal sarcoma (RPS) treated and prospectively followed at a single institution. Between July 1994 and December 2015, 89 patients (36 M, 53 F; mean age 60 years, range 25-79) were evaluated. For the purpose of analysis, complete resection was defined as removal of gross tumor with histologically confirmed clear resection margins. Eighty-three out of the 89 patients (93%), 46 of whom affected by primary RPS, and 37 by recurrent RPS, underwent surgical exploration. Sixty-two had a grossly and microscopically complete resection. Fifty-three out of 83 patients (64%) underwent removal of contiguous intra-abdominal organs. Preoperative mortality was nil and significant preoperative complications occurred in six cases only (7%). High-grade tumor pointed out to be a significant variable for a worse survival in all 83 patients amenable to undergo surgical resection (57% 5 years survival for low grade vs 14% for high grade; P = 0.0004). Among completely resected patients, only histologic grade clearly affected disease-free survival (72% 5 years survival for low grade vs 50% for high grade; P = 0.04), while the role of preoperative blood transfusions (67% 5 years survival for non-transfused patients vs 29% for transfused patients; P = 0.05) has to be evaluated in connection to patient complexity. Histological grade and recurrence are the most valuable prognostic predictors; in this clinical subset, an aggressive surgical approach in both primary and recurrent RPS is associated with a best long-term survival and disease-free survival.

Abstract
Multiple liver tumors represent a challenging condition for abdominal surgeons both in the selection of technique and the rarity of diagnosis. There are no case reports on co-existence of liver metastases from both intestinal leiomyosarcoma and adenocarcinoma. The patient described in this report successfully underwent resection of both primary lesions and liver metastases in combination with chemotherapy. As for the leiomyosarcoma, the primary cecal lesion was revealed more than three years after the patient's first visit. Peritoneal, lymph-node, and lung recurrences were observed afterward, and thus surgeries on those regions were performed. Pathologically, the peritoneal and lung recurrences comprised leiomyosarcoma and the lymph-node recurrence was diagnosed as adenocarcinoma. Despite newly discovered multiple lung recurrences and regional lymph-node metastases, the patient lived a normal life for 73 mo after the initial operation based on multidisciplinary therapy. He ultimately died of liver failure due to invasive lymph-node recurrence from the rectal adenocarcinoma, in addition to multiple lung recurrences from the leiomyosarcoma. Hepatic recurrence did not occur in this patient's case, which appears to be one reason for his long-term survival.

Abstract
In the 2 and half decades reviewed (1970-1995), research established that chromosomal translocation, deletion, and DNA amplification are prerequisites to cancerogenesis and that oncogenes, tumor-suppressor genes, growth factors, and cytokines play crucial roles in the pathomechanism of cancer. Human papillomavirus, human immunodeficiency virus, herpes virus, and hepatitis B virus were identified as cancer-causing viruses. Several laboratory tests were developed for the detection of primary and recurrent cancers, and cancer prevention by screening methods was popularized. Sonography, computerized tomography, magnetic resonance imaging, positron emission tomography, excision of sentinel lymph nodes, and immunohistochemical techniques became routine procedures. Clinicopathologic staging and classification of tumors were standardized. Limited surgery, adjuvant and neoadjuvant chemoradiation, and the therapeutic use of monoclonal antibodies, tumor vaccines, and targeted chemotherapy became routine practice. The decline in cancer incidence and mortality demonstrated that cancer prevention and advancement in oncology are pivotal to success in the crusade against cancer. Above all, it was clearly established that the care of patients with cancer can be accomplished best in a multidisciplinary setting involving surgical oncologists, radiologists, radiation therapists, medical oncologists, surgical pathologists, and laboratory scientists. In conclusion, the 25 years from 1970 and 1995 are the high-water mark in clinical oncology, and this is the period when oncology turned from art to science.

Abstract
BACKGROUND AND OBJECTIVES Soft tissue sarcomas of the head and neck (STSHN) comprise a rare group of malignancies. Our objective is to determine the utility of soft tissue sarcoma staging systems within the head and neck, and to validate an individualized soft tissue sarcoma nomogram within head and neck primary sites. METHODS Previously-untreated patients with STSHN diagnosed and treated between 1982 and 2012 were eligible (n = 319, median follow-up 46 months). Clinical variables were extracted from a prospectively-maintained database. The performance of AJCC/UICC and MSK staging systems and a soft tissue sarcoma-specific nomogram were assessed. RESULTS Four-year overall survival (OS), disease specific survival (DSS), and recurrence-free survival (RFS) were 72%, 76%, and 71%, respectively. AJCC/UICC and MSK staging systems accurately stratified outcomes (OS, DSS, and RFS; P < 0.001 for all comparisons). The nomogram stratified outcomes by quartile (P < 0.001), and predicted risk of death at 4, 8 and 12 years (P < 0.001). Concordance indices for overall survival for the AJCC/UICC system, MSK system, and the nomogram were 0.71, 0.70, and 0.78, respectively. CONCLUSIONS Oncologic outcomes among groups of patients with STSHN can be accurately predicted using both the AJCC/UICC and MSK staging systems. A soft tissue sarcoma-specific nomogram provides reliable, individualized prognostic information for patients with STSHN.

Abstract
BACKGROUND The impact of local recurrence and surgical resection margin status on survival in extremity soft-tissue sarcomas remains to be clearly defined. Our aim was to conduct a retrospective analysis of prospectively collected data to determine the prognostic relevance of positive resection margins and local recurrence for extremity soft-tissue sarcomas for survival. METHODS Three hundred and sixty-three patients who underwent resection of localized primary extremity soft-tissue sarcomas with curative intent were selected from the United States Department of Defense Automated Central Tumor Registry. Outcomes for local recurrence, distant recurrence, disease-specific survival, and overall survival were analyzed according to clinical, pathological, and treatment variables with use of the Kaplan-Meier method (log-rank test) and the multivariate Cox regression model. RESULTS Positive margins (hazard ratio, 1.99 [95% confidence interval, 1.15 to 3.45]), local recurrence (hazard ratio, 2.93 [95% confidence interval, 1.38 to 6.23]), and distant recurrence (hazard ratio, 12.13 [95% confidence interval, 5.97 to 24.65]) were significantly associated with overall survival on multivariate Cox regression analysis. However, for disease-specific survival, local recurrence was not significant and tumor size of >10 cm (hazard ratio, 2.83 [95% confidence interval, 1.15 to 6.95]), positive margins (hazard ratio, 1.95 [95% confidence interval, 1.05 to 3.63]), and distant recurrence (hazard ratio, 9.46 [95% confidence interval, 4.37 to 20.47]) were independent adverse prognostic factors. The disease-specific survival rate for patients with localized soft-tissue sarcomas was 89% (95% confidence interval, 85% to 92%) for five years and 75% (95% confidence interval, 70% to 81%) for ten years. CONCLUSIONS Positive surgical margins are consistently associated with adverse survival-related outcomes in localized soft-tissue sarcomas of the extremity. Local recurrence had a significant impact on overall survival, but not on disease-specific survival.

Abstract
BACKGROUND Based on review of patient data in case conferences over time, we hypothesized that clinically relevant data are omitted in routine soft tissue sarcoma staging. METHODS We examined subsets of a prospectively collected single institution soft tissue sarcoma database with respect to criteria of the AJCC versions 6 (2002) and 7 (2010) staging systems and examined their clinical outcomes. RESULTS Relapse-free survival decreases with increasing primary tumor size in four categories, versus two categories used in AJCC 6 and 7 staging. Disease-specific survival decreases over three categories. Conversely, omission of tumor depth as a prognostic factor in version 7 appears supported, since tumor depth is not an independent risk factor for disease-specific survival by multivariate analysis. Patients with nodal disease and no other metastases fare better than patients with other metastases, but have inferior outcomes compared with patients with large high-grade tumors without nodal metastasis. Multivariate analysis identified size, site, grade, age, nodal metastatic disease, and other metastatic disease as independent risk factors for disease-specific survival. Versions 6 and 7 criteria are tacit regarding anatomic site and histology for tumors with identical FNCLCC grade. CONCLUSIONS Improved patient risk assessment may be achieved by staging using a larger number of size categories. Staging system refinements come at the cost of a larger number of staging categories. Histology or site-specific staging systems, nomograms or Bayesian belief networks may provide more accurate means to assess clinical outcomes.

Abstract
BACKGROUND Leiomyosarcoma is a soft tissue sarcoma whose outcome has historically been confounded by the inclusion of gastrointestinal stromal tumors. Thus, we sought to determine the factors that predict survival and recurrence in patients with primary leiomyosarcoma alone. METHODS During 1982-2006, a total of 353 patients with primary resectable leiomyosarcoma were identified from a prospective database. Multivariate analysis was used to assess clinicopathologic factors for association with disease-specific survival (DSS). Competing risk survival analysis was used to determine factors predictive for local and distant recurrence. RESULTS Of 353 patients, 170 (48 %) presented with extremity, 144 (41 %) with abdominal/retroperitoneal, and 39 (11 %) with truncal tumors. Median age was 57 (range, 18-88) years, and median follow-up was 50 (range, 1-270) months. Most tumors were high grade (75 %), deep (73 %), and completely resected (97 %); median size was 6.0 (range, 0.3-45) cm. Abdominal/retroperitoneal location was associated with worse long-term DSS compared to extremity or trunk (P = 0.005). However, by multivariate analysis, only high grade and size were significant independent predictors of DSS. Overall, 139 patients (39 %) had recurrence: 51 % of those with abdominal/retroperitoneal, 33 % of extremity, and 26 % of truncal disease. Significant independent predictors for local recurrence were size and margin, whereas predictors for distant recurrence were size and grade. Site was not an independent predictor of recurrence; however, late recurrence (>5 years) occurred in 9 % of abdominal/retroperitoneal and 4 % of extremity lesions. CONCLUSIONS Grade and size are significant independent predictors of DSS and distant recurrence. Long-term follow-up in leiomyosarcoma is important, as late recurrence continues in 6-9 % patients.

Abstract
Pediatric soft tissue sarcomas (STS) are a heterogeneous group of malignant tumors constituting about 7% of all cancer cases. Rhabdomyosarcomas (RMS) constitute about half of all soft tissue sarcomas in children, the rest being constituted by non- rhabdomyosarcoma soft tissue sarcomas (NRSTS). Most RMS present in young children <6 y of age while the NRSTS occur in adolescents and young adults. The latter constitute a diverse group of tumors and are rare in children. The STS generally present as painless enlarging mass or with symptoms of compression/infiltration of adjacent organs or structures. Staging, risk stratification and multidisciplinary approach are needed for the treatment of STS and outcome depends on stage, site and histological type. Treatment of RMS has evolved systematically through various clinical trials. Chemotherapy remains the backbone of treatment for RMS and local control is achieved either with surgery or radiotherapy or both. Management of NRSTS is still a challenge as it is generally chemotherapy-resistant and surgery remains the mainstay of treatment. Outcome therefore depends on whether wide local excision with negative margins is possible. Local radiotherapy is reserved for recurrent, residual and large high grade NRST. The prognosis of metastatic as well as recurrent STS remains dismal.

Abstract
Sarcomas are malignant neoplasms originating from mesodermal tissues and constitute less than 1% of body's tumors, including those of the head and neck region. 5-15% of adult sarcomas are in the head and neck region (20% from bones and cartilages and 80% in soft tissues). Commonly encountered sarcomas in the head and neck region are - osteosarcoma, rhabdomyosarcoma, malignant fibrous histiocytoma, fibrosarcoma and angiosarcoma. This article reviews the available literature on head and neck sarcomas.

Abstract
INTRODUCTION Head and neck sarcomas are a heterogeneous group of malignant tumours that vary greatly in clinical presentation, with different histopathological and biological characteristics. MATERIAL AND METHODS This was a retrospective study of patients with sarcoma located in the head and neck treated in our centre over a period of 25 years. RESULTS During the study period, a total of 25 patients were diagnosed with sarcomas in the head and neck, accounting for 0.5% of all malignancies at this level. The most common treatments included surgical resection of the tumour, often supplemented with radiotherapy and/or adjuvant chemotherapy. The final local control, including the salvage, was 52%, with an adjusted survival of 51% at 5 years and 32% at 12 years. CONCLUSIONS Surgical treatment of patients with head and neck sarcomas achieves acceptable results of local control and survival.

Abstract
BACKGROUND The clinical course of patients with uterine leiomyosarcoma (LMS) is difficult to predict with the currently available categorical staging systems of the American Joint Committee on Cancer (AJCC) and the International Federation of Gynecology and Obstetrics (FIGO). The objective of the current study was to develop and validate a novel, clinically relevant, individualized prognostic model for patients with uterine LMS. METHODS Patients with uterine LMS who presented at the authors' institution from 1982 to 2008 were analyzed. The nomogram model was chosen based on the clinical evidence and statistical significance of the predictors, including age at diagnosis, tumor size, histologic grade, uterine cervix involvement, extrauterine spread, distant metastases, and mitotic index. Five-year overall survival (OS) was the predicted endpoint. The concordance probability (CP) was used as a predictive accuracy measure and compared with the CP of current staging systems. The model was internally validated using 200 bootstrap samples to correct for over fitting. RESULTS One hundred eighty-five of 270 patients were eligible for the nomogram analysis. The median follow-up was 5.4 years, and the median OS was 3.75 years (95% confidence interval, 3-6 years). The CP of the newly developed nomogram was 0.67 (95% confidence interval, 0.63-0.72). This was superior to predictions based on AJCC and FIGO staging. The bootstrap-validated CP was 0.65 with good calibration accuracy. CONCLUSIONS The authors developed and internally validated a uterine LMS-specific nomogram to predict 5-year OS. This novel, individualized prognostic model outperforms traditionally used categorical staging systems and may be useful for patient counseling and for better selection of patients for adjuvant therapy trials.

Abstract
PURPOSE To determine the prognostic significance of histologic type in radiation-associated soft tissue sarcomas (RASs) and determine whether RASs are associated with an inferior prognosis compared with sporadic soft tissue sarcomas (STSs). PATIENTS AND METHODS One hundred thirty primary RASs were identified from 7,649 STS patients from 1982 to 2007. Multivariate analysis of clinicopathologic factors for disease-specific survival (DSS) was performed for RASs, and a multivariate analysis of radiation exposure was also performed for RASs and sporadic sarcomas. A matched-cohort analysis was performed for radiation-associated and sporadic malignant fibrous histiocytoma (MFH). Results Most RASs were high grade (83%), deep (87%), and truncal (61.5%). The median interval between radiation therapy and RAS development was 10 years (range, 1.3 to 74 years), which varied significantly by histologic type (P = .003). The 5-year DSS was 58%, and independent predictors were size > 5 cm, margin positivity, and histologic type. Multivariate analysis of histologic types of primary, high-grade radiation-associated and sporadic STSs showed that RAS was associated with a worse DSS (hazard ratio, 1.7; range, 1.1 to 2.4; P = .007). For pleomorphic MFH-the most common RAS type-the 5-year DSS was 44% versus 66% in a matched cohort of sporadic MFH patients (P = .07). DSS was significantly worse in primary RAS malignant peripheral nerve sheath tumors (MPNSTs) compared with unmatched sporadic MPNSTs (P = .001). CONCLUSION Histologic type, margin status, and tumor size are the most important independent predictors of DSS in patients with RASs. DSS in patients with primary RAS is significantly worse compared with sporadic STS independent of sarcoma histologic type.

Abstract
PURPOSE Uterine leiomyosarcoma (LMS) is staged by the modified International Federation of Gynecology and Obstetrics (FIGO) staging system for uterine cancer. We aimed to determine whether the American Joint Committee on Cancer (AJCC) soft tissue sarcoma (STS) staging system is more accurate in predicting progression-free survival (PFS) and overall survival (OS). PATIENTS AND METHODS Patients with uterine LMS who presented at our institution from 1982 to 2005 were staged retrospectively according to a modified FIGO staging system and the AJCC STS staging system. The predictive accuracy of the two staging systems was compared using concordance estimation. RESULTS Two hundred nineteen patients had sufficient clinical and pathologic information to be staged under both systems; 132 patients were upstaged using the AJCC staging system, whereas only four were downstaged. Stage-specific PFS and OS rates for stages I, II, and III differed substantially between the two staging systems. In both systems, there was prognostic overlap between stages II and III. Thus, despite the marked stage-specific differences in 5-year PFS and OS rates for stages I, II, and III, both systems had similar concordance indices. CONCLUSION Estimates of stage-specific PFS and OS for uterine LMS were altered substantially when using the AJCC versus FIGO staging system. Adjuvant treatment strategies should be tested in patients at substantial risk for disease progression and death. Neither the FIGO nor AJCC staging system is ideal for identifying such patients, suggesting a need for a uterine LMS-specific staging system to better target patients for trials of adjuvant therapies.

Abstract
PURPOSE To identify prognostic factors related to outcome in 255 patients with synovial sarcoma and to construct a preoperative nomogram to predict the risk of disease-specific death. DESIGN Between July 1982 and June 2006, 301 patients underwent treatment at our institution for primary synovial sarcoma of all anatomic sites and 255 patients with localized disease at presentation were resected with curative intent. Data were collected prospectively and analyzed retrospectively. RESULTS Five-, 10-, and 15-year disease-specific survival (DSS) was 72%, 60%, and 53%, respectively. Multivariate analysis revealed size and primary tumor site as the only independent adverse predictors of disease-specific death. A nomogram based on preoperative data for surgical patients not receiving anthracycline-ifosfamide (AI) chemotherapy (n = 196) estimates 3- and 5-year DSS with a concordance index of 77.3%. For the first 3 years following diagnosis, the observed DSS for patients treated with AI chemotherapy (n = 59) was greater than that predicted by the preoperative nomogram based on patients not receiving AI chemotherapy. SYT-SSX fusion transcript data were available for 132 patients. Multivariate analysis of this subset showed that SYT-SSX1 fusion type was predictive of early, but not late, distant recurrence. CONCLUSION Size and location govern prognosis in primary synovial sarcoma resected with curative intent. A nomogram based on preoperative variables provides individualized patient survival estimates and shows an early survival benefit to chemotherapy that may dissipate over time. This nomogram may improve decision-making with regards to selecting patients most likely to benefit from neoadjuvant/adjuvant chemotherapy.

Abstract
INTRODUCTION The patterns of failure and mechanisms of sarcoma-specific death are poorly characterized among the minority of patients with low-grade soft tissue sarcoma (STS) who succumb to disease. METHODS Between 1982 and 2006, 2,041 patients aged >or=16 years with low-grade STS of all sites were treated with curative intent and prospectively followed at a single institution. RESULTS Among this cohort, 181 (9%) died from disease (DOD). Overall, 105 patients (58%) died from locally recurrent disease (DOLR), and 59 (32%) died from distant disease (DODR). In 17 patients (9%), the mechanism of sarcoma-related death could not be verified. DOD occurred at a median of 62 months, while median disease-specific survival for the entire cohort was not reached. Median follow-up was 66 months (range 2-431 months). On multivariate analysis, DOD was associated with site, size, and less than R0 resection. For DOLR, site, size, positive margins, liposarcoma histology, and local recurrence (by definition) were significant factors. For DODR, site, histology, and positive margins were not significant factors, while size and local recurrence were. Of DOLR, 80% were retroperitoneal, 68% were liposarcoma, and only 2% were extremity. Conversely, of DODR, extremity (47%) and trunk (18%) were the most common sites, but histology was more variable [liposarcoma 35%, malignant fibrous histiocytoma (MFH) 20%, fibrosarcoma 12%, extraskeletal myxoid chondrosarcoma 10%]. High-grade recurrence rates were comparable between DOLR (27%) and DODR (25%). CONCLUSION Among patients with low-grade STS, DOD occurs in approximately 9% of patients. Nonextremity site, larger size, and less than R0 resection are the most important risk factors for DOD, and distinct patterns of recurrence and death are predicted by primary tumor site.

Abstract
BACKGROUND A consecutive series of 47 patients with retroperitoneal sarcoma (RPS) were resected and prospectively followed. METHOD Between July 1994 and March 2005, 47 patients (24 men, 23 women; mean age, 56 years; range, 17-82 years) were evaluated. RESULTS A total of 23 patients had primary RPS and 24 patients had recurrent RPS. A total of 30 out of 47 patients (64%) underwent removal of contiguous intra-abdominal organs. The peroperative mortality was nil and significant preoperative complications occurred in eight cases only (17%). High tumour grade and incomplete resection were significant variables for a worse survival in all 47 patients, both in the univariate and multivariate analyses (P = 0.008 and P = 0.016, respectively). Among 28 radically resected patients, only histological grade affected overall survival (90% 5-year survival for low-grade tumour vs 26% 5-year survival for high-grade tumour; P = 0.006) with a similar effect noted for disease-free survival. CONCLUSIONS Histological grade was the only factor that affected overall and disease-free survival for RPS tumours. An aggressive surgical approach in both primary and recurrent RPS is associated with long-term survival.

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
Soft tissue sarcomas are a rare group of neoplasms readily dispersed throughout the body with different histopathologies and different outcomes. The present review summarizes advances made in biology, distribution and natural history, and emphasises predictive models for outcome. Complete resection remains the major factor in providing cure, with limited benefits in the control of the local disease by radiation therapy and only minimal benefit of systemic therapy for metastatic disease. Identification of targeted therapy utilising direct specific molecular targets raises hope that future progress in control, if not cure, is realistic.

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
BACKGROUND A nomogram for predicting long term tumor-specific death in patients with soft tissue sarcoma (STS) was developed at the Memorial Sloan-Kettering Cancer Center (MSKCC). METHODS To assess the performance of the MSKCC nomogram, 642 consecutive patients with extremity STS who underwent surgery over a 20-year span at a single referral center were analyzed. Nomogram predictions were based on tumor size, depth, site, patient age, histologic subtype, and grade. The latter, at variance with the system in use at the MSKCC, was classified as Grade 1-3 according to the French Federation of Cancer Centers Sarcoma Group (FNCLCC) system. The statistical approach used for nomogram performance assessment was that of "validation by calibration" proposed by Van Houwelingen. RESULTS Graphic comparison of observed and predicted sarcoma-specific survival curves showed that predictions by the nomogram were quite accurate, within 10% of actual survival for all prognostic strata. Statistical analysis showed that such predictions could be improved by employing approximately 25% shrinkage to achieve good calibration. The contribution of histologic grade was highly significant in both univariate analysis (P < 0.001) and multivariate analysis (P < 0.001), and a survival trend across the 3 grade categories was observed. Based on those findings, a nomogram that included the FNCLCC histologic grade classification was produced. CONCLUSIONS Results of the current study confirmed that the MSKCC nomogram is a valuable tool for individual prognostic assessment. A nomogram that included the FNCLCC histologic grade classification was proposed and was validated internally.

Abstract
INTRODUCTION Radiation therapy is increasingly used as adjuvant treatment of many childhood and adult malignancies. Radiation-induced sarcoma is a well recognized if uncommon event. The objective of this study is to determine the prevalence and long-term outcome for patients who develop radiation-induced sarcomas. METHODS From July 1982 to December 2001, 4884 adult patients with sarcoma were admitted and treated at our institution and recorded in a prospective database. There were 123 (2.5%) patients who had radiation-induced soft tissue sarcomas. Survival was determined by Kaplan-Meier analysis. Patient, tumor, and treatment characteristics were tested for their prognostic significance by log rank and the Cox proportional hazards model. RESULTS The median interval between radiation and development of sarcoma was 103 (6 to 534) months. In 114 patients with radiation-induced sarcoma who underwent curative resection, the 5-year actuarial survival was 41%, with a median survival of 48 months at a median follow-up of 36 months for survivors. The most common malignancy for which radiation was used was breast cancer (29%), followed by lymphoma (16%) and prostate cancer (15%). Malignant fibrous histiocytoma (23%) was the most common histologic diagnosis, followed by fibrosarcoma (15%) and angiosarcoma (15%). High-grade tumors (n = 85; 79%), age > 60 years (n = 61; 50%), and gross positive resection margin (n = 36; 32%) were predictive of poor sarcoma-specific survival on univariate and multivariate analysis. CONCLUSIONS The increasing utilization of adjuvant radiation therapy, especially for early-stage breast cancer mandates long-term follow-up to detect radiation-induced sarcoma. Surgical resection remains the primary therapy, but 5-year survival remains approximately 40%.

Abstract
BACKGROUND The present AJCC/TNM staging system is of limited value for prediction of prognosis for patients with retroperitoneal sarcoma. The objective of the present study was to develop a postsurgical classification system that would enable comparison of outcomes for patients with primary retroperitoneal soft-tissue sarcoma. METHODS Four classes were defined: I, low-grade/complete resection/no metastasis; II, high-grade/complete resection/no metastasis; III, any-grade/incomplete resection/no metastasis; and IV, any-grade/any resection/distant metastasis. The prognostic value of this classification system was analyzed in a population-based multicenter group(MCG) of patients with primary retroperitoneal soft-tissue sarcoma (n = 124) and in a cohort of patients treated in a single tertiary referral center (SCG; n = 107). RESULTS Overall 5-year survival rates were 55% in the SCG and 43% in the MCG (P = 0.02). Class III (incomplete resection) was more frequent in the MCG than in the SCG (33% vs. 16%; P = 0.02). In the SCG, stage-specific 5-year survival rates were 89%, 40%, 26%, and 17% for classes I, II, III, and IV, respectively (P < 0.001), in comparison with 68%, 46%, 24%, and 0% in the MCG (P < 0.001). In a comparison of class-specific survival between the groups, only class I patients in the SCG had significantly better survival than class I patients in the MCG (P = 0.048). CONCLUSIONS Classification based on grade, completeness of resection, and distant metastasis offers a reproducible prognostic tool that can be used to evaluate treatment strategies for primary retroperitoneal soft-tissue sarcoma. The probability of complete resection was significantly higher in the SCG than in the MCG. In patients with low-grade, completely resected sarcoma, there is a significant survival benefit with treatment in a high-volume tertiary center of excellence.

Abstract
BACKGROUND On the basis of a prospectively followed cohort of adult patients with primary soft tissue sarcoma (STS) who were treated at Memorial Sloan-Kettering Cancer Center (MSKCC; New York, NY), a nomogram for predicting sarcoma-specific mortality was developed. Although this nomogram was found to be accurate by internal validation tests, it had not been validated in an external patient cohort, and thus its universal applicability remained unproven. METHODS Between 1975 and 2002, 1167 adult patients (age > or = 16 years) underwent treatment for primary STS at the University of California-Los Angeles (UCLA; Los Angeles, CA). All patients treated with an ifosfamide-based chemotherapy protocol (n = 238) were excluded from the current analysis. The remaining 929 patients constituted the population on which the validation study was performed. The nomogram validation process comprised two activities. First, the extent of discrimination was quantified using the concordance index. Second, the level of calibration was assessed by grouping patients with respect to their nomogram-predicted mortality probabilities and then comparing group means with observed Kaplan-Meier estimates of disease-specific survival. RESULTS With median follow-up intervals of 48 months for all patients and 60 months for surviving patients, the 5-year and 10-year disease-specific survival rates were 77% (95% confidence interval [CI], 74-80%) and 71% (95% CI, 67-75%), respectively. Application of the nomogram to the UCLA data set yielded a concordance index of 0.76, and the observed correspondence between predicted and actual outcomes suggested a high level of calibration. CONCLUSIONS In the current study, the MSKCC Sarcoma Nomogram was found to provide accurate survival predictions when it was applied to an external cohort of patients who were treated at UCLA.

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

Abstract
We have earlier devised a system for soft tissue sarcoma (STS), based on three negative prognostic features: large tumour size, vascular invasion, and microscopic tumour necrosis, the SIN-system. Tumours which exhibit 2 or 3 of these features are categorised as high-risk, the others as low-risk. We have now tested this system for reproducibility both as regards recognition of its components, and as regards prognostic strength in patients from another institution. We have also compared it with the American Joint Committee on Cancer (AJCC) system. 200 patients with STS were analysed, all had been treated by surgery, in 97 patients combined with radiotherapy. The median follow-up for the 117 survivors was 10 (1.5-27) years. Without knowledge of the clinical data, three groups of pathologists independently reviewed original slides from all of the tumours. Based on the factors, the tumours were classified as high-risk or low-risk. The prognostic strength was compared using the results obtained by the different observers. Concordance in recognition of vascular invasion, tumour necrosis, and overall grading was seen in 156 (78%), 154 (77%), and 167 (84%) of the 200 tumours, respectively. Based on the different observers' grading, the cumulative 5-year metastasis-free survival rate (MFSR) varied for patients with low-risk tumours between 0.85 and 0.80, and for patients with high-risk tumours between 0.48 and 0.43. The Kappa-value for grading between all three groups of observers was 0.77. The SIN-system gave more clinically useful prognostic information than the AJCC system. Useful prognostic information in STS can be obtained by using tumour size, vascular invasion and microscopic tumour necrosis. This system provides two distinct prognostic groups, and has a high reproducibility.

Abstract
BACKGROUND We attempted to define the effect of tumor histotype on local recurrence, distant metastasis, and disease-specific survival in patients with surgically treated primary extremity sarcoma. METHODS A total of 951 patients with primary, localized soft tissue extremity sarcoma were followed up prospectively. Patient- and tumor-related variables, including histopathologic type, were used to identify independent prognostic factors for the study end points of local recurrence, distant recurrence, and disease-specific survival. RESULTS There were 137 local recurrences, and significant adverse prognostic factors for local recurrence were patient age >50 years, microscopically positive margins, and malignant peripheral nerve tumor. Adverse prognostic factors for distant recurrence (200 patients) were tumor size >5 cm, tumors beneath the investing fascia, high tumor grade, and leiomyosarcoma. Of the 199 patients who died of disease-related causes, patient age >50 years, tumors beneath the investing fascia, high tumor grade, microscopically positive margin, tumor size >5 cm, leiomyosarcoma, and malignant peripheral nerve tumor were adverse prognostic factors. CONCLUSIONS These data suggest that differences in biological behavior may exist between sarcoma histotypes and deserve further study.

Abstract
OBJECTIVE To identify patient characteristics associated with the development of local recurrence and the effect of local recurrence on subsequent morbidity and mortality in patients with intermediate- to high-grade extremity soft tissue sarcomas. SUMMARY BACKGROUND DATA Numerous studies on extremity soft tissue sarcomas have consistently shown that presentation with locally recurrent disease is associated with the development of subsequent local recurrences and that large tumor size and high histologic grade are significant factors associated with decreased survival. However, the effect of local recurrence on patient survival remains unclear. METHODS From 1975 to 1997, 753 patients with intermediate- to high-grade extremity soft tissue sarcomas were treated at UCLA. Treatment outcomes and patient characteristics were analyzed to identify factors associated with both local recurrence and survival. RESULTS Patients with locally recurrent disease were at a significantly increased risk of developing a subsequent local recurrence. Local recurrence was a morbid event requiring amputation in 38% of the cases. The development of a local recurrence was the most significant factor associated with decreased survival. Once a patient developed a local recurrence, he or she was about three times more likely to die of disease compared to similar patients who had not developed a local recurrence. CONCLUSIONS Local recurrence in patients with intermediate- to high-grade extremity soft tissue sarcomas is associated with the development of subsequent local recurrences, a morbid event decreasing functional outcomes and the most significant factor associated with decreased survival. Although 85% to 90% of patients with high-grade extremity soft tissue sarcomas are treatable with a limb salvage approach, patients who develop a local recurrence need aggressive treatment and should be considered for trials of adjuvant systemic therapy.

Abstract
OBJECTIVE To define the significance of positive microscopic resection margins in a large cohort treated for soft tissue sarcoma. METHODS The authors analyzed 2,084 patients with localized primary soft tissue sarcoma (all anatomic sites) treated from 1982 to 2000. Clinicopathologic variables studied included tumor site, size, depth, histologic type, grade, and resection margin status. Treatment other than resection was not analyzed. Study endpoints included local and distant recurrence-free and disease-specific survival rates, estimated by the Kaplan-Meier method. Univariate and multivariate analyses were performed using the log-rank test and the Cox proportional hazards model. RESULTS Median follow-up was 50 months. After primary resection, 1,624 (78%) patients had negative and 460 (22%) had positive resection margins. Having positive margins nearly doubled the risk of local recurrence and increased the risk of distant recurrence and disease-related death. Seventy-two percent of patients with positive margins had no recurrence. Resection margin did not predict local control for retroperitoneal sarcomas or fibrosarcomas. Resection margin remained significantly associated with distant recurrence-free survival and disease-specific survival across all subsets after adjusting for other prognostic variables. The overall 5-year disease-specific survival rates for negative and positive margins were 83% and 75%. CONCLUSIONS Positive microscopic resection margins significantly decrease the local recurrence-free survival rate for other-than-primary fibrosarcoma and retroperitoneal sarcomas, and independently predict distant recurrence-free survival rates and disease-specific survival rates for all patient subsets. Adjuvant therapy should be considered in the management of soft tissue sarcoma to increase local control. Because 72% of positive margins did not equate with inevitable local recurrence, considerable clinical judgment is required in considering additional treatment. Microscopic resection margins should be considered for inclusion in staging systems and treatment algorithms that address local recurrence.

Abstract
The purpose of this report is to assess the prognostic factors that could influence management and clinical outcome of malignant fibrous histiocytoma (MFH) of soft tissues. Between 1975 and 1998, 109 patients diagnosed with MFH of the soft tissues, seen at King Faisal Specialist Hospital and Research Center, have been reviewed. Of the 109 patients, 75 were men and 34 were women. The median age at presentation was 48 years (range: 3-94). Seven patients (6%) had regional nodal disease and 10 other patients (9%) with distant metastases were excluded from survival analysis. The remaining 92 patients had localized disease and had surgery as the primary treatment modality with or without radiotherapy and/or chemotherapy. Extremities were the most common location (58%). Tumors less than 5 cm represented 32%, whereas 68% had tumors 5 cm or more. Low-grade tumors constituted 46%, and the remaining 54% were high grade. Thirty-seven percent of patients had positive surgical margins histologically after complete gross resection. The 5- and 10-year relapse-free survival (RFS) rates were 39% and 36%, respectively. Isolated local recurrence occurred in 20 patients (22%), isolated metastatic disease without local recurrence in 9 patients (10%), and combined local and metastatic disease occurred in 20 patients (22%). The overall 5- and 10-year overall survival (OS) rates were 50% and 43%, respectively. On multivariate analysis, tumor size and radiation dose were significant factors for RFS (p = 0.04 and 0.0005, respectively). In terms of OS, size, histologic grade, and surgical margins were significant factors on multivariate analysis (p = 0.001. 0.006, and 0.0001, respectively). Complete surgical resection at the time of primary tumor presentation is likely to afford the best chance for RFS and OS. Radiation therapy plays an important role, in combination with surgery for better local control, particularly in high-grade lesions, and in cases with positive surgical margins after wide complete gross excision. The role of adjuvant chemotherapy remains investigational.

Abstract
PURPOSE Few published studies have analyzed risk factors for sarcoma-specific death. We developed and internally validated a nomogram that combines the factors to predict the probability of 12-year sarcoma-specific death using a database of 2,136 prospectively followed adult patients treated at a single institution. PATIENTS AND METHODS Nomogram predictor variables included age at diagnosis, tumor size (< or = 5, 5 to 10, or > 10 cm), histologic grade (high or low), histologic subtype (fibrosarcoma, leiomyosarcoma, liposarcoma, malignant fibrous histiocytoma, malignant peripheral nerve tumor, synovial, or other), depth (superficial or deep), and site (upper extremity, lower extremity, visceral, thoracic or trunk, retrointraabdominal, or head or neck). Death from sarcoma or treatment complication was the predicted end point. Three prediction methods were compared, Kaplan-Meier analysis of all possible subsets, recursive partitioning, and Cox proportional hazards regression analysis. The concordance index was used as an accuracy measure with bootstrapping to correct for optimistic bias. RESULTS Sarcoma-specific death at 12 years was 36% (95% confidence interval, 33% to 39%). The bootstrap-corrected concordance indices were as follows: Kaplan-Meier, 0.69; recursive partitioning, 0.74; and Cox regression, 0.77. A nomogram was drawn on the basis of the Cox regression model. This nomogram was internally validated using bootstrapping and shown to have excellent calibration. CONCLUSION A nomogram has been developed to predict 12-year sarcoma-specific death. This tool may be useful for patient counseling, follow-up scheduling, and clinical trial eligibility determination.

Abstract
Sarcomas of the head and neck are extremely rare, accounting for less than 1% of all neoplasms of the head and neck. These sarcomas arise in both soft tissues and bone and thus cannot be treated by a single approach. The clinical behavior of these tumors varies considerably. Patients with low-grade lesions are prone to local recurrence, whereas those with high-grade lesions develop both local recurrence and disseminated disease. An additional complicating factor is the multiple sites in which sarcomas may arise in the head and neck. All of these factors make it difficult to ascertain the optimal treatment approach for sarcomas. This article reviews the current literature (as well as the author's own experience) and provides a general treatment guideline for sarcomas of the head and neck.

Abstract
BACKGROUND Soft tissue sarcomas (STSs) are heterogeneous neoplasms that have variable clinical outcome. Several clinical parameters and few molecular markers, including Ki-67 proliferative index, have been shown to correlate with patient prognosis. To the authors' knowledge, no definitive report exists to identify one molecular marker that can be analyzed easily in a clinical setting and that predicts survival in a cohort of patients with high-risk STS of identical clinical characteristics but variable outcome. METHODS The influence of clinical prognostic factors was eliminated by selecting two patient groups with identical high-risk characteristics: large (> 10 cm), high-grade, deep, completely resected primary extremity STS (n = 47). Patients in the first group remained disease free (no evidence of disease [NED]) after primary tumor treatment (n = 19), whereas patients in the second group subsequently died of disease (DOD; n = 28). Triplicate 0.6-mm core biopsies from defined morphologic areas of paraffin embedded primary tumors were assembled on a tissue microarray and analyzed by immunohistochemistry with the MIB-1 antibody, and Ki-67 proliferative indices were correlated with patient outcome. RESULTS High Ki-67 proliferative index, defined as greater than 30% tumor cells showing nuclear immunoreactivity, was significantly more frequent in the DOD group than in the NED group and was associated with tumor-related mortality (P = 0.02). This marker identifies an especially aggressive malignant phenotype within a cohort of high-risk tumors that is based on well established clinical and pathologic parameters alone and is easy to use in a clinical setting. CONCLUSIONS On the basis of these data and previous reports, high Ki-67 proliferative index is suggested as a significant factor for predicting the prognosis of patients with high-risk STS and should be evaluated prospectively based on clinical trials.

Abstract
AIM Ten percent of soft tissue sarcomas (STS) arise in the retroperitoneal tissues. The prognosis for patients with retroperitoneal sarcoma is poor with a 5-year survival rate between 12% and 70%. Stage at presentation, high histological grade, unresectable primary tumour and incomplete resection are associated with a less favourable outcome. METHODS Complete follow-up data were available on 22 patients who underwent surgery for retroperitoneal STS in our institution between 1990 and 2000. Patient, tumour and treatment variables were analysed including use of adjuvant therapy and survival status. RESULTS Eighteen patients underwent surgery for primary disease, four patients were treated for recurrent disease or metastases. Ten patients presented with pain, seven with an abdominal mass, other presentation included weight loss and haematuria. Thirteen patients presented with tumours larger than 10 cm. The tumours were seven liposarcomas, six leiomyosarcomas, three malignant fibrous histiocytomas, two rhabdomyosarcomas, two malignant schwannomas and two undifferentiated sarcomas. Six primary tumours were completely excised, five patients received radiotherapy and five received chemotherapy. Local recurrence rate was 45% and recurrence-free interval for 10 patients with recurrence was 11 months. Five patients received radiotherapy and five received chemotherapy. The median survival for patients with primary tumours was 36 months, and 5-year survival was 44%. Adjuvant therapy was not associated with higher survival rates. CONCLUSION This study re-emphasizes the poor outcome of patients with retroperitoneal STS. Adjuvant radiotherapy and chemotherapy do not appear to be any proven benefit and the single most important prognostic factor is aggressive successful en bloc resection of the primary tumour. Our resection rate and 5-year survival rates are comparable with previous reported UK series although lower than large reports from North American centres. This might partly be explained by difficulty in data collection in a retrospective analysis, but may reflect inadequate subspecialization in UK centres.

Abstract
PURPOSE To determine whether treatment-induced pathologic necrosis correlates with local recurrence and overall survival in patients who receive neoadjuvant therapy for high-grade extremity soft tissue sarcomas. PATIENTS AND METHODS Four hundred ninety-six patients with intermediate- to high-grade extremity soft tissue sarcomas received protocol neoadjuvant therapy. All patients underwent surgical resection after neoadjuvant therapy and had pathologic assessment of tumor necrosis in the resected specimens. RESULTS The 5- and 10-year local recurrence rates for patients with > or = 95% pathologic necrosis were significantly lower (6% and 11%, respectively) than the local recurrence rates for patients with less than 95% pathologic necrosis (17% and 23%, respectively). The 5- and 10-year survival rates for the patients with > or = 95% pathologic necrosis were significantly higher (80% and 71%, respectively) than the survival rates for the patients with less than 95% pathologic necrosis (62% and 55%, respectively). Patients with less than 95% pathologic necrosis were 2.51 times more likely to develop a local recurrence and 1.86 times more likely to die of their disease as compared with patients with > or = 95% pathologic necrosis. The percentage of patients who achieved > or /= 95% pathologic necrosis increased to 48% with the addition of ifosfamide as compared with 13% of the patients in all the other protocols combined. CONCLUSION Treatment-induced pathologic necrosis is an independent predictor of both local recurrence and overall survival in patients who receive neoadjuvant therapy for high-grade extremity soft tissue sarcomas. A complete pathologic response (> or = 95% pathologic necrosis) correlated with a significantly lower rate of local recurrence and improved overall survival.

Abstract
BACKGROUND This study was done to review the clinical presentation, surgical management, and prognostic factors for primary gastrointestinal sarcomas. METHODS We reviewed medical records of 55 patients who were treated for primary gastrointestinal sarcomas from 1981 through 1996. Mean follow-up time was 32 months. RESULTS Clinical findings included gastrointestinal bleeding (51%), palpable mass (36%), and abdominal pain (33%). The stomach was the most common site of disease (53%), followed by the small intestine (33%). Tumors were high grade in 76% of patients and low-grade in 24% of patients. Complete resection of all gross disease was accomplished in 35 patients (64%), incomplete resection in 17 patients (31%), and biopsy only in 3 patients (5%). Adjacent organ resection was required in 19 patients (35%). Overall actuarial survival was 22% (median survival, 32 months). Unfavorable prognostic factors were incomplete resection, high-grade histologic features, and tumor size of 5 cm or more (P<.05). En bloc resection of contiguous organs did not adversely effect survival. In patients with complete resections, tumor grade was the most important prognostic factor (median survival, 55 months vs 19 months for low-grade vs high-grade tumors; P<.05). CONCLUSIONS Aggressive surgical resection, including en bloc resection of locally advanced tumors, appears warranted. Despite complete resections, patients with high-grade tumors remain at risk for recurrence.
