Survival Analysis of 3 Different Age Groups and Prognostic Factors among 402 Patients with Skeletal High-Grade Osteosarcoma. Real World Data from a Single Tertiary Sarcoma Center. Cancers (Basel) 2021; 13:486. [PMID: 33513855 PMCID: PMC7865349 DOI: 10.3390/cancers13030486] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2020] [Revised: 01/19/2021] [Accepted: 01/23/2021] [Indexed: 12/18/2022] Open
Abstract
Age is a known prognostic factor for many sarcoma subtypes, however in the literature there are limited data on the different risk profiles of different age groups for osteosarcoma survival. This study aims to provide an overview of survival in patients with high-grade osteosarcoma in different age groups and prognostic variables for survival and local control among the entire cohort. In this single center retrospective cohort study, 402 patients with skeletal high-grade osteosarcoma were diagnosed and treated with curative intent between 1978 and 2017 at the Leiden University Medical Center (LUMC). Prognostic factors for survival were analyzed using a Cox proportional hazard model. In this study poor overall survival (OS) and event-free survival (EFS) were associated with increasing age. Age groups, tumor size, poor histopathological response, distant metastasis (DM) at presentation and local recurrence (LR) were important independent prognostic factors influencing OS and EFS. Differences in outcome among different age groups can be partially explained by patient and treatment characteristics.

Abstract
BACKGROUND The impact of surgical margin status on the survival of patients with extremity soft tissue sarcoma (STS) remains to be clearly defined. The evidence regarding the impact of surgical margins on survival is limited by retrospective single-institution cohort studies. We conducted a systematic review and meta-analysis to examine the impact of surgical margin status on patient survival in extremity STS. METHODS A literature search in the PubMed, EMBASE, and Cochrane Controlled Trials Register electronic databases, and a manual search of reference lists of original studies was performed. The following text words and/or Medical Subject Heading terms were searched: (neoplasm) or/and (sarcoma) and/or (connective tissue) and/or (soft tissue) and/or (extremity) and/or (extremity) and/or (surgical margin). RESULTS Six selected studies that reported a total of 2917 cases of extremity STS were published between 1994 and 2013. All the eligible studies were observational cohort studies, and the sample size ranged from 95 to 1261 patients. A meta-analysis of 6 studies showed that a positive surgical margin predicted poor 5-year OS in a random-effects model (summary hazard ratio, 1.56; 95% confidence interval, 1.12-2.17). Moderate heterogeneity was observed among the studies (P < .075; heterogeneity, 45.6%). CONCLUSIONS This meta-analysis supports the hypothesis that adequate surgical margins are associated with improved survival in extremity STS.

The efficacy of postoperative radiotherapy in localized primary soft tissue sarcoma treated with conservative surgery. Radiat Oncol 2016; 11:25. [PMID: 26911328 PMCID: PMC4766748 DOI: 10.1186/s13014-016-0605-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2015] [Accepted: 02/18/2016] [Indexed: 11/28/2022] Open
Abstract
Background To evaluate the efficacy of postoperative radiotherapy (RT) on local failure-free survival (LFFS), distant metastasis-free survival (DMFS) and overall survival (OS) in patients with localized primary soft tissue sarcoma (STS) and to identify prognostic factors. Methods and materials Between January 2000 and July 2010, 220 consecutive patients with localized primary STS, who received conservative surgery with or without postoperative RT, were enrolled in the study. Survival curves were constructed by the Kaplan-Meier method and log-rank test was used to assess statistical significance. Multivariate analysis was applied to identify the prognostic factors. Results After a median follow-up of 68 months (range, 5–127 months), the 5-year LFFS, DMFS and OS were 70.0, 78.2 and 71.2 %, respectively. Tumor size, histological subtypes, margin status and postoperative RT were independent predictors for OS. Postoperative RT was associated with a significant reduced local recurrence risk versus surgery alone (hazard ratio [HR] = 0.408, 95 % confidence interval [CI] 0.235–0.707, P = 0.001), with 5-year LFFS of 81.1 and 63.6 %, respectively (log-rank, P = 0.004). The log-rank test showed that postoperative RT had a tendency of improving OS compared with surgery alone, with 5-year OS of 74.8 and 65.0 %, respectively (P = 0.089). Multivariate analysis demonstrated that postoperative RT significantly reduced mortality rate compared with surgery alone (HR = 0.512, 95 % CI 0.296–0.886, p = 0.017), especially in patients with liposarcoma (p = 0.034). Conclusion Postoperative radiotherapy reduce both local recurrence and STS mortality in patients with localized primary STS. The efficacy of RT on survival warrants further prospective study.

Abstract
Pelvic soft tissue sarcomas are rare tumors often presenting larger than other soft tissue sarcomas and can extend into the thigh through various anatomic routes. Surgical resection is the main modality of curative treatment. En bloc tumor excision with wide, negative margins may reduce the risk of local recurrence. Soft tissue sarcomas extending through the obturator foramen create unique challenges to operative management. This case report describes 2 cases of lipomatous lesions that extend through the obturator foramen, presenting as dumbbell-shaped lesions with large intra- and extrapelvis portions. One possible surgical approach performed in both patients is detailed with long-term follow-up. Postoperatively, 1 incidence of infection was reported. Functional outcomes were acceptable, with full restoration of ambulation without assistive devices in both cases and no hernia observed. Oncologic outcomes included locoregional recurrence in 1 patient at 24 months outside the radiation field. The ideal primary treatment for all localized soft tissue sarcomas, including those extending through the obturator foramen, is resection. However, the unique subgroup of obturator ring soft tissue sarcomas has undefined outcomes and complications. The authors' goal was to achieve en bloc resection with wide negative margins while preserving ipsilateral limb function. The surgical approach described in this case study offers a description of feasibility and discussion of theoretical and observed complications.

Abstract
OBJECTIVES We reviewed our institution's experience in treating soft tissue sarcomas of the extremity to identify factors associated with local recurrence, metastasis, and overall survival, to identify patients who may benefit from intensification of therapy. METHODS A retrospective analysis was performed for patients who underwent both limb-sparing surgery and external beam radiotherapy for extremity sarcoma. Those who had gross residual disease or who presented with recurrent or metastatic disease were excluded. The Kaplan-Meier product limit and multivariate Cox regression were used to estimate local failure-free probability, distant failure-free probability, and overall survival along with associations with patient, tumor, and treatment characteristics. RESULTS One hundred eighty-eight patients were included in the analysis. Twenty-five (13%) and 46 (24%) experienced local and distant recurrence, respectively. Patients with high/intermediate-grade tumors [hazard ratio (HR)=5.63, 95% confidence interval (CI): 1.27-24.89, P=0.023] or with multifocally positive margins (HR=4.27, 95% CI: 1.20-15.24, P=0.026) were more likely to fail locally. Those with a preceding local recurrence (HR=8.58, 95% CI: 3.87-19.04, P<0.0001), high/intermediate-grade tumors (HR=5.68, 95% CI: 1.28-25.25, P=0.023), or no secondary reexcision (HR=2.5, 95% CI: 1.09-5.74, P=0.031) were more likely to develop metastasis. Patients with local recurrence (HR=3.6, 95% CI: 1.77-7.29, P<0.001), metastasis (HR=16.0, 95% CI: 7.93-32.31, P<0.0001), or without secondary reexcision (HR=3.2, 95% CI: 1.27-8.09, P=0.014) had decreased overall survival. CONCLUSIONS Patients whose tumor grade or margin status put them at high risk for local failure should be considered for intensification of therapy. Those with a local recurrence should be considered for increased surveillance or systemic therapy, as local failure is associated with subsequent metastasis and decreased survival.

Abstract
Objective. We have investigated whether there is evidence that patients with soft tissue sarcomas do better if treated in a
specialist centre compared with district general hospitals. Patients. All patients diagnosed with soft tissue sarcomas who were residents of WMRHA between 1994 and 1996, with
minimum follow up of 5 years, excluding head and neck or retroperitoneal tumors. Methods. We reviewed data from the Royal Orthopaedic Hospital Oncology Service (ROHOS) database and the Cancer
Intelligence Unit (CIU) Database, with medial record review where necessary. Main outcome measures were local
recurrence and overall survival. Results. A total of 260 patients were diagnosed as having STS over the 3-year period (incidence=1.62per 100000 per
year): 37% of patients had the majority of treatment at the specialist centre under the care of three surgeons, whilst the other
63% were treated at a total of 38 different hospitals. The rate of local recurrence was 39% at the district general hospitals
compared with 19% at the specialist centre despite the fact that tumours treated at the district hospitals were smaller and of
lower grade. The most significant factors affecting survival were grade (high versus low) and depth of the tumour. Patients
treated at the specialist centre had a small survival advantage after multivariate testing. Conclusion. Soft tissue sarcomas are rare. Centralization of treatment improves local control in all patients and survival in
some. Appropriate mechanisms for ensuring that patients with soft tissue sarcomas are seen and treated at specialist centres
should be developed.

Abstract
Soft-tissue sarcomas are a heterogeneous group of tumors consisting of approximately 100 distinct diagnoses. Management requires a multimodality approach with the input of pathologists, surgeons, radiation oncologists, medical oncologists and radiologists. In localized disease, the primary modality of treatment is wide-resection surgery, and the use of radiation therapy has improved local control rates for high-grade tumors. Currently, most localized tumors can be managed with limb-sparing treatment, and local control rates of 80-90% can be seen with appropriate management. Improvements in classification and diagnosis of these tumors have led to the current idea that the specific histology is an important consideration when developing a treatment plan and may affect prognosis, although existing staging systems have not yet incorporated this parameter. Treatment of metastatic disease continues to be difficult, but current research focuses on clarifying molecular mechanisms of disease and identifying new potential targets for medical therapy. This review focuses on the current status of management of these tumors including a review of epidemiology, initial evaluation, and treatment including surgical, radiation, and medical aspects.

Abstract
BACKGROUND The aim was to review a single-institution experience of a prospective treatment protocol for soft tissue sarcoma of the extremity and trunk wall, with particular focus on the smallest surgical margin leading to local control. METHODS The study included 270 patients who had surgery for soft tissue sarcoma at Helsinki University Central Hospital between 1987 and 1997. Resection margins were measured prospectively from tumour specimens. Radiotherapy was administered if the smallest margin measured less than 2.5 cm, irrespective of tumour grade. RESULTS With a median follow-up of 6.6 years, the 5-year local control rate was 76.4 per cent. On multivariable analysis, the smallest surgical margin around the sarcoma (after radiotherapy) was prognostic for local control. A margin of at least 2.5 cm was associated with a local recurrence-free rate of 89.2 per cent at 5 years. Tumour size, depth or grade and patient's age had no independent prognostic effect on local control. CONCLUSION Surgical margin had independent prognostic value for local control. A surgical margin of 2-3 cm provided reasonable local control of soft tissue sarcoma, even without radiotherapy. Radiotherapy is recommended for smaller margins, irrespective of tumour grade.

Abstract
Abstract
Background
This study investigated the value of intravascular ultrasonography (IVUS) in the intraoperative assessment of vascular invasion of soft tissue sarcoma.
Methods
In a 4-year interval, of 337 patients with soft tissue sarcoma, 20 patients with tumours of the lower limb in close relation to the neurovascular bundle underwent intraoperative IVUS (20 MHz). Intraoperative findings were correlated with preoperative imaging, histopathological appearance of the resection specimen and patient outcome.
Results
Intraoperative IVUS was technically successful in all 20 patients. It correctly predicted vascular involvement (true positive) in ten of 11 patients who required resection of major vessels. There was one false-negative and one false-positive result. With magnetic resonance imaging, there were ten true-positive and three false-positive scans, and one false-negative diagnosis. IVUS improved the assessment of vascular involvement in four of the 20 patients. Histopathological examination confirmed complete resection (R0) in 18 patients. Mean survival was 37 months, and no local recurrence was observed in these patients.
Conclusion
Vascular infiltration by soft tissue sarcoma can be visualized accurately by IVUS. This may improve intraoperative decisions about vessel resection.

Abstract
AIMS Patients with invasive breast cancer submitted to conservative treatment must be followed for a long period of time to study locoregional control. In this study, we analysed the outcome and relationships between locoregional recurrence (LRR), distant metastases and survival. MATERIALS AND METHODS A 15-year study, including 470 women with early breast cancer, stage I and II, who underwent breast conservative treatment. Tumour size, nodal status, age, menopausal status, histological grade and LRR were analysed for their ability to predict overall survival, disease-specific survival and distant disease-free survival. RESULTS With a median follow-up time of 6.6 years (3 months to 19.1 years), there were 19 LRR at their first site of recurrence and 53 distant metastases. Tumour size greater than 2 cm, positive lymph nodes and histological grade III were significantly related to lower overall and distant metastases-free survival. On multivariate analysis, nodal status, histological grade III and LRR (coded as a time-dependent variable) were significantly related to overall, specific and distant metastases-free survival, whereas tumour size had only a borderline effect on specific and distant disease-free survival. Landmark analysis showed that women who presented an LRR within 2 years after surgery had significantly lower distant disease-free survival (hazard ratio [HR]: 8.39; 95% CI 2.56-27.47; P < 0.001), specific survival (HR: 8.19; 95% CI 2.45-27.41; P < 0.001) and overall survival (HR: 6.02; 95% CI 2.25-16.11; P < 0.005). CONCLUSIONS LRR seems to be a significant predictor of distant metastases and survival, and patients who sustain early LRR tend to display a more aggressive clinical course.

Abstract
OBJECTIVE To assess the role of recurrence in prognosis of colon cancer, we investigated several methodologic issues, including application of classic survival analysis and Markov model. STUDY DESIGN AND SETTING The data were recorded by the Registry of Digestive Tumors of Côte d'Or, France, for 874 patients who had been treated by surgery between 1976 and 1984 and followed for up to 11 years. Survival analyses included the Cox proportional hazards model and its two generalizations that allow recurrence to be taken into account as a time-dependent covariate or as a competing outcome. The Markov model was used to analyze simultaneously recurrence and death. RESULTS The competing risks approach is not appropriate because censoring is indisputably informative. The Markov model and the Cox model, with recurrence as a time-dependent covariate, provided similar results, demonstrating the impact of age and gender on recurrence and revealing a reduction in the effect of site and stage on mortality. CONCLUSION A Markov multistate model seems to give new insights about the course of digestive cancer progression and into the role of recurrence in this process.

Abstract
AIMS The aims were to review the existing methods of quality assurance in surgical oncology and to determine a relationship between surgery-related factors and the variety in outcomes in the treatment of solid cancers. METHODS The literature was reviewed by searching Medline and Cancerlit databases. RESULTS Wide variations were found in virtually all tumour types. Clear evidence was found that an improvement in the quality of the surgical procedure could have major implications for the prognosis and quality of life of cancer patients. CONCLUSIONS These findings emphasize the need for strict quality control procedures in surgical oncology and might imply a considerable change in cancer treatment strategies, because the routine use of adjuvant therapies could be questioned.

Abstract
Forty-five patients with soft tissue sarcomas received additional wide resections after they were treated with simple excision by a primary physician. Of the patients in the current study, 26 were male and 19 were female; all were treated between 1986 and 1998 for malignant soft tissue tumors. The mean followup was 7.1 +/- 3.4 years. The mean time from first excision to additional wide resection was 8 weeks, and for 90% of the patients it was within 12 weeks. In deciding the surgical margin for an additional operation, enhanced computed tomography scans and magnetic resonance images were done. Four (8.8%) patients had local recurrences that required a second resection and had no evidence of disease at latest followup. Four (8.8%) patients had distant metastases but did not have local recurrences. Three patients died of lung metastases. The overall 5-year survival rate of the patients was 93%, and the overall 5-year disease-free rate was 84%. It seems that tumors treated adequately by wide resection in an additional operation have results as good as tumors treated with a primary wide resection.

Abstract
BACKGROUND Local recurrence occurs in 10% to 20% of patients with extremity soft tissue sarcomas despite optimal treatment. The association of local recurrence with subsequent survival is controversial and conflicting. There is a need for a staging system to predict outcome in this subset of patients and also to plan optimal treatment, including adjuvant systemic therapy. METHODS Data collected from 110 patients with locally recurrent extremity soft tissue sarcomas were studied. The influence of clinical and pathologic factors on local recurrence, distant metastasis, and disease-specific survival were analyzed by univariate and multivariate techniques. RESULTS Of the 110 patients who presented with local recurrence, 92 had an isolated local recurrence and 18 had prior or concomitant distant metastases. The 5-year disease-specific survival for all patients was 63% and for those with isolated local recurrence, it was 69%. Histologic grade, malignant fibrous histiocytoma histology, pathologic margins, previous local recurrence, and prior radiotherapy were independent prognostic factors for subsequent local recurrence. Tumor size, histologic grade, and time to local recurrence were independent prognostic factors for distant metastasis and disease-specific survival. A prognostic index was calculated by assigning a score of 1 to 3 for each of the three independent prognostic factors for survival and added to give the prognostic index for each patient. As the prognostic index increased from 3 to 9, there was a progressive increase in the hazard ratios and a corresponding deterioration in survival. The patients were then categorized into three prognostic groups based on the hazard ratios for disease specific survival. The differences in the survival curves were highly statistically significant (P < .0001). CONCLUSIONS Tumor size, histologic grade, and time to local recurrence are the primary determinants of distant metastases and survival in locally recurrent extremity soft tissue sarcomas. The impact of local recurrence on survival varies considerably. The nature of the local recurrence, rather than its presence per se, is a more useful guide to prognosis. We propose a simple staging system based on size, grade, and time to recurrence that correlates extremely well with prognosis and may serve as a guide to make therapeutic decisions in patients with locally recurrent extremity soft tissue sarcomas.

Abstract
The aim of this study was to assess the effect of local recurrence on survival in primary osteosarcoma. 559 patients entered into two randomised trials of the European Osteosarcoma Intergroup who received surgery for primary operable high-grade osteosarcoma of the extremities were included in this analysis. Proportional hazards modelling techniques were used to assess the relative importance of sex, age, site, surgery performed and local recurrence. The last of these was considered as a time-dependent covariate. 42/559 (8%) patients had a local recurrence. In the multivariate analysis, local recurrence was found to greatly increase the risk of death (hazard ratio (HR)=5.10, 95% confidence interval (CI) 3.51-7.41). Site and surgery performed also had a significant influence within this model. Using the technique of landmark analysis, with the landmark time set at 18 months, local recurrence alone had a significant influence on survival (HR=4.60, 95% CI 2.80-7.57). Local recurrence is an indicator of poorer survival for patients with operable primary osteosarcoma.

Abstract
Sarcomas of the soft tissues are challenging lesions for the surgical oncologist. Careful planning must be done at all stages of diagnosis and treatment, because every sarcoma is unique with respect to histologic type, size, and location. Pretreatment discussions in a multidisciplinary format are useful to ensure appropriate and effective management of these tumors.

Abstract
Local tumor recurrence after complete resection may be due to treatment factors or represent a manifestation of tumor biology. The association of local tumor recurrence, distant metastases, and death in patients undergoing treatment for extremity soft tissue sarcoma (STS) has been described but continues to be enigmatic. After definitive multimodality treatment for extremity STS, local tumor recurrence is associated with development of distant metastasis, and metastases are implicated in subsequent disease-specific death. The relationship is an enigma, and the causality is unclear. Conversely, for patients with retroperitoneal STS, a direct relationship between local tumor recurrence and disease-specific death has been shown. In this article, current concepts are analyzed and reviewed.

Abstract
Significant advances have been made in the understanding of clinicopathologic prognostic factors for soft tissue sarcoma over the past decade. Foremost among these advances is an improved ability to recognize the subset of patients at high risk for recurrent disease based on clinicopathologic data available at the time of initial presentation. Progress has also helped to elucidate specific molecular factors that have independent prognostic significance. This review outlines the updated American Joint Committee on Cancer staging system for soft tissue sarcoma and summarizes the available data on traditional clinicopathologic and molecular prognostic factors.

Abstract
BACKGROUND The aim of this study was to determine how and by which specialties patients with soft tissue sarcoma are investigated and treated within a single large health region and with what outcomes and implications for resource uptake. METHODS By retrieving the records of 377 patients with primary soft tissue sarcoma treated in the South-East Thames Region between 1986 and 1992, the presentation, investigation, treatment and outcome were compared with defined criteria for optimal management. Patient management was assessed and compared between specialties and districts on the basis of outpatient time, appropriate use of radiological investigations and preoperative biopsy, type of surgery, content of the pathology report and the incidence of local recurrence, metastasis and death over a mean follow-up period of 2.5 years. RESULTS Most patients (53.6 per cent) were treated by general surgeons, irrespective of tumour location. Overall only 21.3 per cent of patients were investigated optimally with wide variation among specialties. Only 60.0 per cent were treated adequately (wide excision or surgery with radiotherapy). Uptake of adjunctive therapy and follow-up were variable. Outcome was poorer in patients having a marginal excision and recurrence. CONCLUSION Investigation and management of many patients with soft tissue sarcoma was both variable and suboptimal. This has implications for patient care, resource uptake and costs. As has been amply demonstrated elsewhere, patients with sarcoma are more appropriately managed in specialist centres.

Abstract
The local treatment of soft tissue sarcoma is evolving. Limb-sparing compartmentectomy offers local control but at the expense of function and a high amputation rate. The functional outcome is improved with combined wide excision and radiotherapy, at the same time achieving a similar local control rate. Future directions should include attempts to reduce toxicity and maximise the functional result. As the limb function is ultimately related to the aggressiveness of the local treatment, the optimum surgical margin, radiation volume and dose, require further investigation. The pursuit of local control should not be compromised in the quest for reducing morbidity, as the relationship between local control and survival remains unclear.

Abstract
In 1987, a multidisciplinary soft tissue sarcoma (STS) group was established and a treatment protocol was set up. By 1993, there were 193 patients with a diagnosis of STS of the superficial trunk or extremities. 134 patients were referred with primary (stage M0) tumours and treated with curative or palliative intention. Nine amputations were performed. 94 (70%) patients were treated with wide or compartment surgery (n = 62) or marginal surgery combined with postoperative radiotherapy (n = 32). According to the protocol, these patients had received adequate treatment. 18 patients have recurred locally (13%) (median follow-up: 36 months). 12 were salvaged. 33 had metastases. The estimated 3-year survival, local control and disease-free survival rates are 79, 87 and 69%, respectively. These results compare favourably with previously published results from this hospital and from a nationwide study. The improved results emphasise the importance of a multidisciplinary STS group.

Abstract
We performed a retrospective analysis of 379 adult patients treated for soft tissue sarcoma. None had metastasis at the time of diagnosis and all were treated surgically. Patients who developed metastatic disease before the local recurrence were excluded. The 8-year metastasis-free survival rate in the group of 261 patients with local tumor control was 0.72, compared to 0.67 in the 118 patients with local recurrence (P 0.2). Multiple regression analysis showed that high-grade malignancy and large tumor size were risk factors for metastases. Local recurrence was not a risk factor. However, when patients with small and/or low-grade tumors were analyzed separately, local recurrence emerged as a risk factor. In this group of patients, the 8-year survival rate was 0.87 for those with local control and 0.64 for those with local recurrence (P 0.004). Local recurrence appears to be a risk factor for the development of late metastases in patients who otherwise have a low risk of metastases.

Abstract
PURPOSE A prospective randomized trial evaluating adjuvant brachytherapy for soft tissue sarcomas was conducted between July 1982 and July 1987. METHODS AND MATERIALS One hundred twenty-six patients with soft tissue sarcoma of the extremity or superficial trunk (STS) underwent grossly complete resection with limb-sparing surgery. Intra-operatively, patients were randomized to receive either adjuvant brachytherapy (BRT) or no further therapy (no BRT). BRT consisted of an Iridium-192 implant which delivered 4200-4500 cGy over 4-6 days. Total hospital stay for combined surgery and BRT was 10-14 days. Patients in each group were well matched with respect to age, sex, site, tumor size, depth, histologic type, and grade. Median follow-up is 66.5 months for all living patients. RESULTS At 5 years, local control was 82% in the BRT group vs. 67% in the no BRT group (p = .049). When analyzed by histologic grade, high grade tumors had local control of 90% with BRT vs. 65% with no BRT (p = .013). There was no difference in local control in the low grade patients in either arm. At 5 years, the proportion free of distant metastases was approximately 76% in both arms, with no difference between BRT and no BRT. When analyzed by grade, high grade patients had a similar proportion free of distant metastasis in the BRT vs. no BRT arms despite improved local control in those receiving BRT. Similarly, the disease-specific survival for all patients at 5 years was 81% for BRT vs. 80% for no BRT (p = NS). When analyzed by grade, and treatment (BRT vs. no BRT), 5-year disease-specific survival for high grade was the same in both groups. CONCLUSIONS Adjuvant BRT significantly improves local control in completely resected STS. This improvement is confined to patients with high grade histology. BRT provides excellent local control in this group, and significantly shortens the treatment time when compared to adjuvant external beam radiation. However, the improved local control does not translate into either decreased distant metastasis or increased disease-specific survival.

Abstract
The karyotypic pattern at different stages of tumor development may provide information on tumor progression but few data are available regarding human solid tumors. Cytogenetic analysis was performed on the primary tumor and four lung metastases of a synovial sarcoma, and the primary tumor, two consecutive local recurrences, and six pulmonary metastases, obtained at two different occasions, of a malignant fibrous histiocytoma (MFH). Simultaneous existence of more than one cytogenetically aberrant clone was also assessed through analysis of more than one sample from the same surgical specimen. Clonal chromosome aberrations were detected in all samples from the synovial sarcoma, and in both local recurrences and five of the metastases from the MFH. All clones in both tumors were cytogenetically related. The primary synovial sarcoma tumor contained two clones, one of which was also found in the lung metastases, together with a third clone that had acquired additional aberrations. Four clones with a near-tetraploid chromosome number and complex aberrations were identified in the MFH. Likely evolutionary pathways could be deduced in both cases. In the patient with synovial sarcoma one of the pulmonary metastases, rather than the primary tumor, might well have been the source of another of the pulmonary metastases. In the MFH the cytogenetic findings indicated the presence of two co-existing lineages in the primary tumor, one giving rise to the local recurrences and one to the pulmonary metastases. Our findings show that cytogenetic analysis can be used to establish the chronologic relationships between different clones in primary tumors, local recurrences and distant metastases, to determine what genetic changes are of importance for the metastatic capability of tumor cells, and to help establish the origin of the metastatic lesions.
