Larios F, Gonzalez MR, Ruiz-Arellanos K, Aquilino E Silva G, Pretell-Mazzini J. Is Unplanned Excision of Soft Tissue Sarcomas Associated with Worse Oncological Outcomes?-A Systematic Review and Meta-Analysis. Cancers (Basel) 2024; 16:443. [PMID: 38275885 PMCID: PMC10814439 DOI: 10.3390/cancers16020443] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2023] [Revised: 12/28/2023] [Accepted: 01/16/2024] [Indexed: 01/27/2024] Open
Abstract
BACKGROUND Soft tissue sarcomas are a group of rare neoplasms which can be mistaken for benign masses and be excised in a non-oncologic fashion (unplanned excision). Whether unplanned excision (UE) is associated with worse outcomes is highly debated due to conflicting evidence. METHODS We performed a systematic review and meta-analysis following PRISMA guidelines. Main outcomes analyzed were five-year overall survival (OS), five-year local recurrence-free survival (LRFS), amputation rate and plastic reconstruction surgery rate. Risk ratios were used to compare outcomes between patients treated with planned and unplanned excision. RESULTS We included 16,946 patients with STS, 6017 (35.5%) with UE. UE was associated with worse five-year LRFS (RR 1.35, p = 0.019). Residual tumor on the tumor bed was associated with lower five-year LRFS (RR = 2.59, p < 0.001). Local recurrence was associated with worse five-year OS (RR = 1.82, p < 0.001). UE was not associated with a worse five-year OS (RR = 0.90, p = 0.16), higher amputation rate (RR = 0.77, p = 0.134), or a worse plastic reconstruction surgery rate (RR = 1.25, p = 0.244). CONCLUSIONS Unplanned excision of Soft Tissue Sarcomas and the presence of disease in tumor bed after one were associated with worse five-year LRFS. Tumor bed excision should remain the standard approach, with special consideration to the presence of residual disease.

Abstract
Background Synovial Sarcoma (SS) is a rare soft tissue sarcoma. Mean time to get a SS diagnosis from the onset of symptoms is 10 years, furthermore, SS is associated with late metastasis. Surgery is the main treatment option, whose quality deeply affects SS outcomes, and it can be associated to preoperative or post-operative radiotherapy. Chemotherapy is considered very effective in Children, while in adults its efficacy is still under debate. The aim of this study was to investigate the oncologic results in SS treatment and to identify the risk factors for local and systemic control of the disease. Methods From 1994 to 2018, 211 patients affected by SS were treated in 3 Referral Centres of Orthopaedic Oncology. One hundred seventy-seven patients were included in the study, the median follow-up length was 96 months (5-374). Results Overall Survival on the Kaplan Meier Analyses was 80%, 70% and 56% at 5, 10 and 20 years. In multivariate analyses, OS correlated with tumour size and negative surgical margins. Chemotherapy use wasn't associated with better survival although patients who underwent CT had bigger and more aggressive tumours. Conclusions Our findings suggests that surgery with negative margins is the most important factor in Synovial Sarcoma. Adjuvant treatments as chemotherapy and radiation therapy didn't change the disease's course.

Abstract
In Soft Tissue Sarcomas (STS) referral centre many patients have already had an incomplete tumour resection. In the majority of specimen, tumoral residual is detected and linked to a worsen prognosis. Systematic surgical re-resection of the scar tissue area is often performed. Some authors suggested to postpone re-resections until a clinically evident local recurrence is detected. A searching strategy was applied to Pubmed-Central and Ovid Medline. Odds ratio (OR) for local recurrence (LR), distant metastasis (MTS) or overall survival (OS) were calculated comparing patients who had tumour residual to people who hadn't. OR of local recurrences, distant metastasis and OS were calculated in planned vs unplanned-excisions groups. OR to develop a metastasis and OS after a local recurrences were calculated. Residual tumour led to an OR for LR of 3,56, OR of MTS was 3,42; OR of decreased OS was 3,42. Having a LR lead to a OR of 1,55 for MTS and to a OR of decreased OS of 2,32. Patients who underwent a re-excision compared to planned surgery did not have an increased OR of LR and had an OR to develop a MTS of 0,56. Our data confirm that there is a strong correlation between local recurrences, distant relapses and overall survival. Although there is a selection bias; this analysis highlights the optimal oncological outcome in patients who underwent re-resection. The rationale for systematic re-resection after unplanned excision of soft tissue sarcomas is very strong and this treatment remains the gold standard of care in these patients.

Abstract
Sarcomas are an infrequent and heterogeneous group of neoplasia. Surgery with or without associated radiotherapy (RT) is the basic treatment for this type of tumour. To increase the therapeutic ratio (the index between cytotoxic effects in tumours and normal tissue complications with a certain dose of radiation), new advances are being investigated to increase local and distant control and to decrease the morbidity of the treatment. The aim of this review was to analyse the different strategies, based on technology and biology, which are being investigated to increase the therapeutic ratio of this disease.

Abstract
Background Historically, local control of recurrent sarcomas has been limited to radiotherapy when surgical re-resection is not feasible. For metastatic carcinomas to the bone or soft tissue, radiotherapy and some interventional radiology treatment along with other systemic therapies have been widely advocated due to the possibility of disseminated disease. These techniques are effective in alleviating pain and achieving local control for some tumor types, but it has not been effective for prolonged local control of most tumors. Recently, cryoablation has been reported to have satisfactory results in lung and liver carcinoma treatment. In this study, we analyzed the clinical outcome of CT-guided cryoablation for malignant bone and soft tissue tumors to elucidate potential problems associated with this procedure. Methods Since 2011, 11 CT-guided cryoablations in 9 patients were performed for locally recurrent or metastatic bone and soft tissue tumors (7 males and 2 females) at our institute. The patients’ average age was 74.8 years (range 61–86) and the median follow up period was 24.1 months (range 5–48). Histological diagnosis included renal cell carcinoma (n = 4), dedifferentiated liposarcoma (n = 2), myxofibrosarcoma (n = 2), chordoma (n = 1), hepatocellular carcinoma (n = 1), and thyroid carcinoma (n = 1). Cryoablation methods, clinical outcomes, complications, and oncological outcomes were analyzed. Results There were 5 recurrent tumors and 6 metastatic tumors, and all cases had contraindication to either surgery, chemotherapy or radiotherapy. Two and 3 cycles of cryoablation were performed for bone and soft tissue tumors, respectively. The average length of the procedure was 101.1 min (range 63–187), and the average number of probes was 2.4 (range 2–3). Complications included 1 case of urinary retention in a patient with sacral chordoma who underwent prior carbon ion radiotherapy, 1 transient femoral nerve palsy, and 1 minor wound complication. At the final follow up, 4 patients showed no evidence of disease, 2 were alive with disease, and 3 died of disease. Conclusions Reports regarding CT-guided cryoablation for musculoskeletal tumors are rare and the clinical outcomes have not been extensively studied. In our case series, CT-guided cryoablation had analgesic efficacy and there were no cases of local recurrence post procedure during the follow-up period. Although collection of further data regarding use of this technique is necessary, our data suggest that cryoablation is a promising option in medically inoperable musculoskeletal tumors.

Abstract
BACKGROUND The purpose of this study is to investigate functional outcomes and cost impacts of immediate functional reconstruction performed in conjunction with limb-sparing resection of upper extremity soft tissue sarcomas. METHODS Patients undergoing simultaneous limb-sparing upper extremity soft tissue sarcoma resection and functional reconstruction between December 1998 and March 2004 were retrospectively identified, their medical records reviewed, and costs of surgery analyzed. Functional outcomes and patient satisfaction were assessed via patient surveys and the Toronto Extremity Salvage Score (TESS). RESULTS Thirteen patients met the inclusion criteria. Average follow-up was 43.3 months. Reconstructions included rotational innervated muscle flaps (n = 6), free innervated myocutaneous flaps (n = 1), and tendon transfers or grafts (n = 6). Overall survival was 85 % (n = 11) and disease-free survival was 77 % (n = 10). Average total cost of surgery was $26,655. Patients undergoing reconstruction for hand and forearm sarcomas had significantly higher total costs of surgery than those undergoing reconstruction for elbow and upper arm sarcomas. Survey response rate was 91 % (n = 10). Average TESS score was 76. Of the patients who worked preoperatively, 88 % returned to work postoperatively, and all patients who returned to work currently use their affected limb at work. CONCLUSIONS Patients undergoing immediate functional reconstruction for upper extremity soft tissue sarcoma resection achieved very good to excellent functional outcomes with quick recovery times and a high return-to-work rate following immediate functional reconstruction, thereby minimizing surgical cost impacts. Immediate functional reconstruction in the same surgical setting is thus a viable strategy following upper extremity soft tissue sarcoma resection.

Abstract
BACKGROUND The 5-year survival rates for localized liposarcomas reportedly vary from 75% to 91% with histologic grade as the most important prognostic factor. However, it is unclear which other factors, including the initial surgery quality and recurrent tumors, influence survival in localized liposarcomas (LPS). QUESTIONS/PURPOSES We analyzed factors (including AJCC staging system) influencing survival and local control of resectable LPS of the extremities/trunk wall and the impact of surgery quality and tumor status and type of disease recurrences according to pathological subtype. METHODS We retrospectively reviewed 181 patients with localized LPS: 110 were treated for primary tumors, 50 for recurrent tumors, and 21 for wide scar resection after unplanned nonradical resection. We determined survival rates and examined factors influencing survival. The minimum followup was 4 months (median, 52 months; range, 4-168 months). RESULTS Five-year disease-specific (DSS), disease-free (DFS), and local relapse-free survival (LRFS) rates were: 80%, 58%, and 75%, respectively. Five-year local relapse-free survival rates for primary versus clinically recurrent tumor versus scar after nonradical resection were: 86.1%, 52.1%, and 73.3%, respectively. The following were independent negative prognostic factors for DSS (AJCC Stage ≥ IIb), DFS (Grade 3; clinical recurrence; skin infiltration), and LRFS (clinical recurrence; R1 resection). An unplanned excision, although influencing local relapse-free survival, had no impact on disease-specific survival (calculated from date of first excision 5-year rate of 80%, considering impact of combined treatment of clinical recurrence/scar). CONCLUSIONS We confirmed the value of AJCC staging for predicting disease-specific survival in extremity/trunk wall LPS. Radical reresection of scar after nonradical primary tumor resection (+ radiotherapy) seems to improve disease-free and local relapse-free survival in liposarcomas. Patients with unplanned excision can be cured when referred to a sarcoma unit. LEVEL OF EVIDENCE Level IV, prognostic study.

Abstract
BACKGROUND Major amputations are indicated for advanced tumors when limb-preservation techniques have been exhausted. Radical surgery can result in significant palliation and possible cure. METHODS We identified 40 patients who underwent forequarter (FQ) or hindquarter (HQ) amputations between May 2000 and January 2011. Patient demographics, tumor-related factors, and outcomes were reviewed. RESULTS There were 30 FQ and 10 HQ amputations. The most common diagnoses were sarcoma (55%) and squamous cell carcinoma (25%). Patients presented with primary tumors (35%), regional recurrence (57.5%), or unresectable limb metastatic disease (7.5%). Presenting symptoms included fungating wounds (35%), intractable pain (78%), and limb dysfunction (65%). Operations were performed with curative intent (10%), curative/palliative intent (70%), or palliation alone (20%). Wound complications occurred in 35%. Pain was improved in 78% of patients following surgery. Despite a 91% negative margin rate, 79% of patients recurred either locally or distantly. Median overall survival was 10.9, 13.2, and 3.4 months in the curative, curative/palliative, and palliative groups, respectively. CONCLUSIONS In the absence of conservative options, major amputations are indicated for the management of advanced tumors. These operations can be performed safely, resulting in effective palliation of debilitating symptoms. While recurrence rates remain high, some patients can achieve prolonged survival.

Abstract
PURPOSE To evaluate whether adjuvant radiotherapy (RT) in extremity and truncal soft-tissue sarcoma (STS) patients with microscopically positive or close margins after excision can achieve comparable local control to that of excision with negative margin plus RT. METHODS AND MATERIALS A total of 150 patients (111 extremity and 39 trunk cases) treated with conserving surgery and adjuvant RT was analyzed. All surgical margins were classified as being a negative margin or a positive or close margin based on pathologic margin width. RT was delivered with a shrinking-field technique in 150 patients (median, 63 Gy). RESULTS All patients were divided into two groups: (A) excision with negative margins plus RT (n = 56) and (B) excision with positive or close margins plus RT (n = 94). Overall, the 5-year local failure-free survival in all patients was 72.9%, and no significant differences were found between the two groups (Group A, 74.7%; Group B, 71.6%). High tumor grade was found to be a significant predictor of local failure. However, Group A was superior to Group B in distant metastasis-free survival (p = 0.02). No significant differences were shown in overall survival between the two groups. CONCLUSIONS In our series, margin status did not predict for LF when adjuvant RT was used. We believe that when adjuvant RT is used, re-resection may not be necessary for selected patients with positive or close pathologic margins in the management of extremity and truncal STS patients.

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

Abstract
PURPOSE To analyze the management and clinical outcome of patients treated for a first isolated local recurrence of soft tissue sarcomas (trunk or extremities) and to identify prognosis factors. METHODS AND MATERIAL Between 1980 and 1999, 83 adult patients were included in the study. Mean age was 61 years. Mean tumor size was 6 cm. Most sarcomas were located in extremities (n=74), were deep (n=60), and proximal (n=53); 30 involved nerves or vessels. Histologic subtypes were mainly grade 2 (42%) or 3 (36%) histiocytofibrosarcomas (49%) and liposarcomas (20%). Surgical treatment of recurrences consisted in wide excision (29 cases), marginal resection (43 cases), 5 patients requiring amputation. Final results were R0 (n=33), R1 (n=47) or R2 (n=3) resection. Besides surgery, 6 patients received neo-adjuvant and 7 others adjuvant chemotherapy. Twenty three patients received post-operative external beam radiotherapy (EBRT) (mean dose 55 Gy) and 26 interstitial 192Ir low dose rate brachytherapy (BCT) (mean dose 45 Gy for BCT alone, 22 Gy when associated with EBRT), 19 patients being re-irradiated. RESULTS Mean follow up was 13 years. Thirty-seven (45%) patients relapsed, 62% of whom presenting an isolated local recurrence. Nineteen patients developed distant metastases. Multivariate analysis showed only tumor depth (P=0.05) and re-resection for primary R1 resection (P=0.018) being independent prognosis factors for tumor control, radiotherapy (EBRT and/or BCT) being significant in univariate analysis (P=0.05). Overall survival rate was 73%, 54%, and 47% at, respectively, 3.5 and 10 years, and was 65%, 35% and 32% after a further local recurrence. Multivariate analysis showed trunk (P=0.0001) or inferior extremity locations (P=0.023), symptomatic (P=0.001), high grade (P=0.01), deep (P=0.01) tumors, and the occurrence of a further local failure (P=0.004) as unfavorable characteristics for overall survival. CONCLUSIONS A first isolated local recurrence of STS increases mainly the risk of a subsequent local relapse. Quality of local treatment is decisive. When a conservative treatment is feasible, it should combine surgical resection and radiotherapy, BCT being the best suited in previously irradiated patients. Efforts have to be pursued to increase quality of the treatment of primary tumors, at best performed in centers that have expertise in this field.

Abstract
PURPOSE To analyse the management and clinical outcome of patients treated for a first isolated local recurrence of soft tissue sarcoma (trunk or extremities) and to identify prognosis factors. PATIENTS AND MATERIAL This is a retrospective study of 83 adult patients treated between 1980 and 1999. Mean tumor size was 6 cm. Most sarcomas were located in extremities (N =74), were deep (N =60), and proximal (N =53). Thirty involved nerves or vessels. Histologic subtypes were mainly grade 2 (42%) or 3 (36%) histocytofibrosarcomas (49%) and liposarcomas (20%). Surgical treatment of recurrences consisted in wide excision (32 cases), marginal resection (46 cases), five patients requiring amputation. Final results were R0 (N =33), R1 (N =47) or R2 (N =3) resection. Beside surgery, six patients received neoadjuvant and seven others adjuvant chemotherapy. Twenty-three patients received postoperative external beam radiotherapy (EBRT) (mean dose 55 Gy) and 26 interstitial (192)Ir low dose rate brachytherapy (BCT) (mean dose 45 Gy for BCT alone, 22 Gy when associated with EBRT), 19 patients being re-irradiated. RESULTS Mean follow up was 59 months. Thirty-seven (45%) tumors relapsed, 62% locally as first event. Nineteen patients developed secondary distant metastases. Multivariate analysis showed only tumour depth (P =0.05) and re-resection for primary R1 resection for the recurrence (P =0.018) being independent prognosis factors for tumour control, radiotherapy (EBRT and/or BCT) being significant in univariate analysis (P =0.05). Overall survival rate was 73, 54, and 47% at respectively 3, 5 and 10 years, and was 65, 35 and 32% after a further local recurrence. Multivariate analysis showed trunk (P =0.0001) or inferior extremity locations (P =0.023), symptomatic (P =0.001), high grade (P =0.01), deep (P = 0.01) tumours, and the occurrence of a further local failure (P =0.004) as unfavourable characteristics for overall survival. CONCLUSION Because of the high relapse rate in this series, a first isolated local recurrence of STS increases mainly the risk of a subsequent local relapse. Quality of local treatment for the first local relapse is decisive. When a conservative treatment is feasible, it should combine surgical resection and radiotherapy, brachytherapy being the best suited in previously irradiated patients. Efforts have to be pursued to increase quality of the treatment of primary tumours, at best performed in centers that have expertise in this field.

Abstract
BACKGROUND Biopsy of musculoskeletal tumours is hazardous and, when poorly performed, can compromise limb salvage surgery and patient survival. The aim of the present paper is to examine the early management of such patients referred to the Department of Orthopaedic Surgery, Royal Prince Alfred Hospital, Sydney, Australia with particular reference to biopsy. METHODS We conducted a prospective audit of all patients referred to our musculoskeletal tumour service during 2002. Inclusion criteria were: all patients with primary tumours of the musculoskeletal system. We compared the outcome of patients biopsied prior to referral with that of patients biopsied in a recognized treatment centre. RESULTS One hundred and forty-two patients were included. The referring surgeon performed biopsies in 29 cases, of which 20 were malignant lesions. The senior author biopsied the remaining 113 cases, of which 57 were malignant. Definitive treatment was hindered by a badly performed biopsy in 38% of patients biopsied by the referring surgeon. In 25% the definitive treatment had to be changed either to a more radical procedure than would have originally been necessary or to palliative rather than curative intent. Patients biopsied elsewhere were more likely to have an incomplete excision requiring re-excision, more likely to require amputation, and more likely to require adjuvant radiotherapy. CONCLUSIONS There is a high complication rate when patients with musculoskeletal tumours are biopsied by surgeons inexperienced in their management. These patients are better served by early referral to a specialist centre where staging investigations including biopsy can be performed with minimal morbidity.

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
BACKGROUND AND OBJECTIVES To evaluate the significance of resection margin for soft tissue sarcoma (STS), we determined local recurrence-free interval (LRFI), distant metastases-free interval (DMFI), and overall survival (OS) for primary extremity and truncal STS with clear margins (> or =10 mm), close margins (1-9 mm), and positive margins (0 mm). METHODS Patients were evaluated via review of charts and tumor specimens. RESULTS Among 111 patients, tumors were predominantly high grade (86%), > or =5 cm (76%), and deep (81%). A minority of patients received adjuvant radiation (38%) and/or adjuvant chemotherapy (34%). Margin width was > or =10 mm (48%), 1-9 mm (40%), or 0 mm (12%). Margins > or =10 mm were less common for large (P = 0.009) or deep (P = 0.02) tumors. By multivariate analysis, independent factors for LRFI were tumor size (P = 0.04) and margin width (P = 0.03). Independent factors related to DMFI were tumor grade (P = 0.002), size (P = 0.007), and patient age (P = 0.02). Independent factors relating to OS were tumor grade (P = 0.001), size (P = 0.004), and depth (P = 0.03). CONCLUSIONS Margins > or =10 mm independently predicted longer LRFI and are optimal for extremity STS resection. Adjuvant radiotherapy should be considered for all STS resected with margins <10 mm, and margin width should be considered when reporting and interpreting LR outcomes for these patients.

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

Abstract
AIMS The aim of this study was to report prognostic factors, end-points of local recurrence, distant recurrence, post-metastasis survival, and overall survival in a cohort of patients with soft tissue sarcomas. METHODS We analysed a database of 395 patients affected by primary soft tissue sarcomas of various primary sites, treated and followed up at the Centro di Riferimento Oncologico, Aviano, Italy from January 1985 to January 1997. RESULTS Grade, size, stage, surgical margins, distant metastasis, age, sex, performance status, and haemoglobin value were significant for overall survival. Histology, grade, stage, and surgical margins were significant for local recurrence. Grade, size, and stage, were significant for distant recurrence; and surgical margin was significant variable for post-metastasis survival. CONCLUSIONS Grade, size, and TNM stage (UICC/AJCC) have stronger prognostic significance for overall survival and distant recurrence than for local relapse. Positive surgical margins are the main predictors for local relapse. Age was the most consistent adverse independent prognostic factor for survival.

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
From the Scandinavian Sarcoma Group Register, information on 1,224 surgically-treated patients with soft tissue sarcoma (STS) of the extremity or trunk wall, diagnosed between 1987 and 1995, was collected. 205 patients, one third of whom were referred to a center with a local recurrence, had a total of 284 local recurrences. This analysis describes the treatment for these local recurrences, complications and risk of further recurrences. 169 patients were surgically treated for their first local recurrence. An intralesional or marginal margin was achieved in 110 of these patients, 59 of whom were also given radiotherapy. 54 of the 169 patients had a second local recurrence. The second local recurrence rate was 0.50 if the first local recurrence had been treated with only surgery with a marginal margin, compared to 0.28 if treated with surgery with a marginal margin and radiotherapy or with a wide margin (p = 0.0008). In extremity STS, the crude amputation rate for local recurrences was 0.22 (31 of 142)-i.e., higher than for primary tumors 0.09 (96 of 1065) (p < 0.0001). A high local recurrence rate after treatment outside of sarcoma centers has earlier been shown. We conclude that the consequences of local recurrence in terms of morbidity and costs justifies referral of STS patients for multidisciplinary evaluation and multimodality treatment.

Abstract
AIMS To identify independent adverse clinico-pathological factors for disease-free and overall survival in patients undergoing isolated limb perfusion (ILP) with cisplatin and doxorubicin for locally advanced soft tissue sarcoma (STS) of an extremity. METHODS A retrospective analysis was carried out, using a univariate method and a multivariate analysis, to look at the patient, tumour and treatment associated with prognostic factors in 37 patients with locally advanced STSs of the limbs who underwent ILP with cisplatin and doxorubicin. Patient's age, gender, presenting status, tumour location, tumour grade, tumour stage according to TNM classification, tumour size and radiotherapy (RT) were analysed. Survival curves were calculated according to the Kaplan-Meier method. A Cox proportional hazard model was used to indicate which factors related to overall survival and the recurrence-free interval after ILP. RESULTS No major systemic toxicity was seen. Regional toxicity was limited. Limb salvage was achieved in 94.6% of the patients. The estimated 5-year overall and disease-free survival rates were 62% and 54%, respectively. It was found that tumour stage, tumour grade, presenting status, RT and tumour size were associated with cumulative overall survival when the Kaplan-Meier method was applied (P<0.05). By Cox proportional hazards model, only tumour grade (P=0. 0254) was found to have significant influence on overall survival; however, tumour stage (P=0.0157) and RT (P=0.0014) were related to disease-free survival. CONCLUSIONS ILP and delayed excision followed by RT achieves good limb salvage rates and may improve survival.

Abstract
The prognostic importance of surgical margins on local recurrence rates and metastasis-free survival (MFS) was studied in 559 patients with soft tissue sarcoma of the extremities and trunk wall. The patients were all surgically treated, but received no adjuvant treatment. The median follow-up for the survivors was 7.4 (range: 0.1 - 12.5) years. Independent prognostic factors for MFS were analysed by Cox models. The overall 5-year MFS was 0.72 (95% confidence intervals (CI) 0.68 - 0.76). High histopathological malignancy grade (relative risk (RR) 3.0; 95% CI 1.5 - 6.3) and an inadequate surgical margin (RR 2.9; 95% CI 1.8 - 4.6) were independent risk factors for local recurrence. High histopathological malignancy grade and large tumour size (> 7 cm) were the most important risk factors for metastasis. Local recurrence was associated with an increased risk of metastasis (RR 4. 4; 95% CI 2.9-6.8), but an inadequate surgical margin was not a risk factor for metastasis (RR 1.1; 95% CI 0.8-1.7). This study confirms that, as regards metastasis, tumour-related risk factors (malignancy grade and tumour size) are more important risk factors than treatment-related factors. Local recurrence was associated with an increased metastasis rate, whereas inadequate surgical margin was a risk factor for local recurrence but not for metastasis. Hence, the proposed causal association between local recurrence and metastasis is doubtful, and if it exists is a weak association.

Abstract
BACKGROUND AND OBJECTIVES Soft-tissue sarcomas (STS) represent a diverse histologic group of malignancies at risk for local and distant failure. We studied the impact of late (5 or more years) vs. early recurrence (less than 5 years) on subsequent outcome. METHODS Four hundred sixty-eight patients with STS treated between 1962 and 1992 were evaluated for late (n = 39; 8%) or early (n = 253; 54%) recurrence. Clinical and pathologic factors were reviewed. Survival data were analyzed by the Kaplan-Meier method and the log-rank test. RESULTS Of the 39 patients with a late recurrence (median follow-up 156 months), 18 patients had local recurrence, 7 patients developed distant recurrence, and 14 patients had local and distant recurrence. Thirty patients with late local and/or distant recurrence underwent complete or wide excision (n = 16), amputation (n = 4), or local resection (n = 10). The overall 5-year survival rate following late recurrence was 61%. The 5-year overall survival rate was statistically better for patients with a late local recurrence alone than for patients with distant failure, 94% vs. 36%, respectively (P = 0.003). Neither the site of the primary STS, age, primary margin status, nor histology had any effect on subsequent local or distant failure and subsequent survival. CONCLUSIONS These data suggest that an aggressive approach is appropriate in patients who present with late recurrence (more than 5 years) following treatment of the primary STS. Impressive survival rates can be achieved in the treatment of local recurrences.

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 Local control remains an important issue in the management of large soft tissue sarcomas. Radiation is the main adjuvant to surgery for local therapy of sarcomas, but it requires relatively high doses, hitherto considered prohibitive in areas such as the retroperitoneum. We developed a preoperative treatment approach to large soft tissue sarcomas that would deliver a high total dose of radiation administered in conjunction with the halogenated pyrimidine radiosensitizer idoxuridine (IdUrd). METHODS Thirty-seven patients with large sarcomas of the head and neck, mediastinum, retroperitoneum, or extremity received three or five cycles of sequential IdUrd infusion (1000-1600 mg/m2/d x 5 d) alternating weekly with twice daily radiation (125-150 cGy per dose) and were then evaluated for resection. The delivered preoperative radiation dose was up to 6250 to 7500 cGy. RESULTS Five patients (14%) had a partial response to preoperative therapy, and 28 of 37 patients underwent successful resection. There were no intra- or postoperative deaths. Local control was achieved in 19 of 28 resected patients, but in only 1 of 6 patients who remained unresectable despite therapy. With a median follow-up of 5.8 years, 28% of patients are alive with no evidence of disease, 17% are alive with disease, and 53% have died of their disease. CONCLUSIONS Using the dose and schedule we employed, resection of large soft tissue sarcomas was possible after high-dose radiation delivered in conjunction with IdUrd. Although local control was acceptable, the high rate of distant failure represents a limitation of any local approach to the treatment of large soft tissue sarcomas and suggests the need for integration of this approach with an effective systemic therapy.

Abstract
BACKGROUND Soft tissue sarcomas (STS) of the extremities are rare. The purpose of this study was to identify prognostic risk factors associated with survival in patients with primary extremity and truncal STS. METHODS Patient, tumor, and pathologic data from 149 consecutive patients with localized primary STS of the extremities and trunk were analyzed using Kaplan-Meier and Cox regression techniques to identify univariate and multivariate risk factors. A subgroup analysis was performed to compare factors predictive of survival in patients who received treatment before (n = 50) and after (n = 99) treatment was standardized in 1988. RESULTS The 5-year survival rate was 76.5% with an average follow-up of 6 years. Local recurrence occurred in 23% of all patients, 40% before 1988 and 15% after 1988 (P < 0.0001). Risk factors associated with survival included resection quality (R0 vs. R1; P < 0.0001), era of operation (P = 0.002), local recurrence (P < 0.001), UICC stage (P < 0.0001), tumor size (P < 0.001), tumor depth (P = 0.002), regional lymph nodes (P < 0.0001), and histology (P < 0.0001). Multivariate analysis revealed that tumor size, tumor depth, and resection quality were independent risk factors of survival. CONCLUSIONS These results indicate that management of STS in a specialized institution improves overall survival. Resection quality is the most important risk factor of survival. Therefore, effort should be made during primary treatment of STS to achieve wide, tumor-free resection margins.

Abstract
The aim of this experimental study in dogs was to assess the tissue toxicity of doxorubicin (DOX) and the impact of dose and pharmacokinetics after double isolated limb perfusion (ILP). Fifteen beagle dogs were assigned to three groups of five animals each. In the first ILP 0.75 mg/kg bodyweight (bw) DOX was given to all animals. In the second perfusion after an interval of 6 to 8 weeks the dosage was 0.5 mg/kg bw in group I, 0.75 mg/kg bw in group II, and 1.0 mg/kg bw in group III. At the same dosage tissue toxicity increased in comparison to the first ILP. At the second ILP there was a dose-toxicity relationship. At a dose of 0.75 mg/kg bw pharmacokinetics of DOX in the perfusate showed no significant differences between first and second perfusion. The mean muscle tissue levels during the second ILP were lower than during the first perfusion. However, in contrast to the first perfusion, they showed a further increase after perfusate eluation. A disturbed microcirculation caused by intima proliferations in arteries and arterioles fter the first ILP may impair the removal of DOX from the intravasal and interstitial compartment and can be assumed as a reason for increased tissue toxicity. Therefore, we recommend a reduction of DOX dose in the second ILP for clinical use.

Abstract
BACKGROUND Isolated limb perfusion (ILP) with tumor necrosis factor alpha (TNF alpha) +/-interferon gamma (IFN gamma) and melphalan in patients with primarily irresectable soft tissue sarcoma is promising in terms of tumor regression and limb salvage. However, the feasibility of radiotherapy in combination with this treatment modality has not been established. METHODS Fifteen patients with irresectable soft tissue tumors of the limb underwent ILP with TNF alpha, +/-IFN gamma, and melphalan. Three groups could be distinguished with respect to the role of radiotherapy. In nine patients, the residual tumor could be resected after ILP, and this was followed by radiotherapy with a total dose of 50-70 Gy (2 Gy/day). In one patient with aggressive fibromatosis, ILP was followed by radiotherapy without tumor resection (Group I). In two patients who underwent ILP for recurrent sarcoma, the primary tumor had been treated before by resection and radiotherapy (60 Gy) (Group II). In three patients whose tumors remained irresectable after ILP, radiotherapy was applied later in the course of disease for local palliation (Group III). RESULTS In Group I, healing of the resection wound was markedly delayed in four patients, with soft tissue necrosis and infection necessitating amputation in two of them. Following completion of radiotherapy, persistent lymphoceles were encountered in two patients. Radiotherapy-induced fibrosis was encountered in five patients, resulting in a mild limb malfunction in two. Three-patients developed mild edema during radiotherapy. Tumor-associated neuropathy was aggravated by ILP in three patients causing severely disabling motor deficits and limb contractures in two of them. In Group II, ILP did not cause any local problem in the heavily irradiated areas. In Group III, pre-existing limb edema was increased after a total palliative dose of 20 Gy in one patient. Another patient, who had been re-operated for arterial thrombosis immediately after ILP, developed occlusion of the brachial artery 4 months after completion of palliative radiotherapy (36 Gy in 6 Gy fractions). CONCLUSIONS In patients with irresectable soft tissue tumors, multimodality treatment using ILP with TNF alpha +/- IFN gamma and melphalan, tumor resection, and postoperative high-dose radiotherapy is associated with a considerable risk of tissue necrosis and impaired healing. This risk should be weighed against a possible benefit from radiotherapy in local tumor control.

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
Purpose. Post-operative radiotherapy (RT) is routinely applied in the treatment of several human tumours. The aim of
the present study was to investigate the value of post-operative RT in a rat model. Methods. Experiments were performed using the rhabdomyosarcoma R1H of the WAG/Rij rat. Animals were randomized
to different treatment schedules: surgery, RT or a combination of both. Tumours were excised at different sizes (0.1–4.5 g)
aiming for complete macroscopic resection. RT (60 Gy in 30 daily fractions over 6 weeks) was applied either primarily or to
the former turnout site from the third post-operative day. Tumour growth delay, time to recurrence and local tumour control
were used as endpoints. Results. Pre-operative tumour size determined the time and rate of recurrence. The larger the tumour,
the shorter the time to relapse and the higher the recurrence rate. The 50% local control rate (LCR50) for surgery was found in tumours
with a mass of 0.8 g. For post-operative RT a LCR50
was achieved for tumours with a mass of 1.1 g. For larger turnouts
(> 1.1 g), however, the rate and time course of relapse were similar for both the group receiving RT alone and the group
receiving post-operative RT. Discussion. In this model the tumour mass at excision governs the prognosis. Relatively small R1H turnouts may recur
despite complete macroscopical resection. With regard to the LCR, the outcome for larger tumours is improved with
post-operative RT (60 Gy/6 weeks) than compared with surgery alone. The factor is 1.3. Within a certain range of tumour
sizes, combined treatment (surgery + RT) can improve the outcome considerably.

Abstract
Soft tissue sarcomas are relatively rare tumors with an annual incidence of 5000 to 6000 in the United States. The primary therapy is surgical resection with an adequate margin of normal tissue. For patients at high risk local control is improved with postoperative adjuvant radiation. Local recurrence rates vary depending on the anatomic site. In extremity lesions one third of patients will have locally recurrent disease with a median disease-free interval of 18 months. Treatment results for extremity local recurrence may approach those for primary disease. Isolated pulmonary metastases may be resected with 20% to 30% 3-year survival rates. Patients with sarcomas in other sites present similar but more difficult problems in terms of local control and management of disseminated disease. Patients with unresectable pulmonary metastases or extrapulmonary metastatic sarcoma have a uniformly poor prognosis and are best treated with systemic chemotherapy.

Abstract
The purpose of this study is to evaluate the radiation sensitivity of human soft tissue sarcoma cell lines in vitro and to compare with that of human breast carcinoma and glioblastoma cell lines. The intrinsic radiation sensitivity parameters of seven human soft tissue sarcomas and eight breast carcinoma cell lines were investigated in vitro by clonogenic assays for single-dose irradiation under aerobic conditions on cells in exponential phase of growth. The results for sarcoma cell lines showed that the mean surviving fraction at 2 Gy (SF2) was 0.39 (SD +/- 0.09) with a range of 0.24 to 0.53, and the average mean inactivation dose (MID) was 1.92 (SD +/- 0.35) range from 1.36 Gy to 2.49 Gy. These values were not different from that of breast cell lines examined concurrently and using the same experimental methods (mean SF2 0.38, SD +/- 0.09; MID 1.9 Gy, SD +/- 0.37). However radiobiological parameters of nine karyotyped human malignant glioma cell lines determined earlier in this laboratory were significantly higher (mean SF2 0.50 +/- 0.14; mean MID 2.61 +/- 0.60). In conclusion, the data presented here do not support the view that cells of sarcomas show unusual radiation resistance. To the extent that the in vitro determined cellular radiation sensitivity reflects the tumor response in vivo, the success rate for radiation applied against sarcoma and breast carcinoma of comparable size could be similar.

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
External beam radiation may be given either before or after excision of a primary soft tissue sarcoma. This study was undertaken to determine whether or not the timing of radiotherapy was associated with any difference in either local control, survival, or incidence of complications. The files of 112 patients with a primary, nonmetastatic, extremity soft tissue sarcoma, treated with limb salvage surgery and irradiation were evaluated. Data regarding tumor stage, grade, site, surgical margin, dosage and timing of radiotherapy, treatment complications, disease relapse, and relapse-free survival (RFS) were analyzed. Kaplan-Meier lifetable analysis was used to determine survival estimates. There was no significant difference in the 5-year RFS between patients receiving radiotherapy (RT) preoperatively versus postoperatively; 56 +/- 15% and 67 +/- 12% (P = 0.12, Mantel-Cox), respectively. There was no significant difference in the overall survival between patients receiving RT preoperatively versus postoperatively; 75 +/- 15% and 79 +/- 11% (P = 0.94), respectively. Actuarial local control at 5 years for preoperative versus postoperative RT patients was not statistically different; 83 +/- 12% versus 91 +/- 8% (P = 0.41), respectively. Wound complications were more frequent in preoperative RT patients (31%) compared to postoperative RT patients (8%) (P = 0.0014, chi-square). Preoperative irradiation was not associated with any benefit in terms of relapse-free survival, overall survival or actuarial local control in this series. A higher incidence of major wound complications was found among patients treated with preoperative irradiation. We recommend that patients with a resectable extremity soft tissue sarcoma be treated with postoperative irradiation, reserving preoperative irradiation for those situations in which either the tumor is initially thought to be unresectable or the original tumor boundaries are obscured.

Abstract
Soft tissue sarcomas (STS) tend to recur locally. In a series of 140 patients operated on during the past two decades with STS of the extremities and trunk, prognostic factors influencing local recurrence were determined. Statistical significance was evaluated for the quality of surgical resection (P < 0.001), regional positive lymph nodes (P = 0.03), and adjuvant radiotherapy (P = 0.01) [for resection without wide margins (R1) and low-grade (G3) tumors]. In 1988, the surgical procedure was standardized. After 1987, local recurrence decreased significantly (P < 0.001). In subfascial tumors, local recurrence occurred far less in cases of compartmental resection than with wide excision. These data indicate that the course of patients with STS can be beneficially influenced by optimal therapy. Resection with wide margins in all three dimensions is the aim of sarcoma surgery. Postoperative radiation therapy is indicated in the case of R1 resection.

Abstract
To determine the value of proliferating cell nuclear antigen (PCNA) staining as a prognostic indicator in soft-tissue malignant fibrous histiocytoma (MFH), we studied 27 patients who underwent resection including an adequately wide margin but without chemotherapy. The survival rate of patients with a lesion in which less than 70% of the cells was positively stained was significantly higher (P < 0.01) than of those with more than 70% positive staining. Twenty-two patients (81.5%) evidenced disease-free survival (mean follow-up period 4.6 years), 1 patient was alive with disease, and 4 (14.8%) died of the disease with lung or lymph node metastasis. In all 4 patients who died, PCNA staining was over 70% positive. In 2 of them, an increase in the number of PCNA-positive cells was observed after repeated recurrence. We conclude that PCNA is a useful prognostic indicator which provides a quantitative measure of the grade of malignancy in MFH patients who receive operative treatment without chemotherapy.

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
BACKGROUND Limb-sparing surgery for soft tissue sarcomas of the extremities may result in microscopically positive surgical margins. The consequences of these microscopically positive margins are unknown. We have analyzed the influence of surgical margins on local disease control and overall survival in patients with extremity soft tissue sarcomas who received preoperative radiation therapy followed by limb-sparing surgery. METHODS Ninety-five consecutive patients with intermediate and high grade extremity sarcomas who received preoperative radiation therapy and limb-sparing surgery were identified from a soft tissue sarcoma data-base. The clinical outcome of 24 patients who had microscopically positive surgical margins was compared with that of 71 patients who had clear surgical margins. RESULTS Multivariate statistical analysis revealed that patients with microscopically positive surgical margins or intraoperative tumor violation had an increased risk for local failure. High grade, large size, and intraoperative violation of the tumors were associated with decreased overall survival. However, neither the presence of a positive surgical margin nor the occurrence of a local failure adversely affected overall survival. CONCLUSIONS Achieving negative surgical margins in patients with intermediate and high grade extremity sarcomas enhances local disease control but does not measurably improve overall survival. These data should be factored into patient management decisions in cases where the goal of achieving clear surgical margins requires amputation or the significant functional compromise of the extremity.

We review and discuss the practical problems encountered when analysing the effect on survival of covariates which are measured repeatedly over time. Specific issues arise over and above those met with the standard proportional hazards model and concern all stages of data preparation, data analysis and interpretation of the results. Data from a randomized clinical trial of patients with primary biliary cirrhosis, on whom several measurements were taken at regular intervals after entry, are presented as an illustration.

Abstract
PURPOSE To evaluate the outcome, patterns of failure and prognostic factors in this rare disease in adult patients treated at a single institution in the modern era. METHODS AND MATERIALS The records of all patients (389 cases) with soft tissue sarcoma in the extremities, torso (excluding retroperitoneum), and head and neck managed between 1980 and 1988 were reviewed. A curative (radical) approach was used in 321 patients of whom 10% were recurrent lesions. The local management consisted of surgery alone in 54 cases, surgery and radiotherapy in 250 and radiotherapy alone in 17. Adjuvant chemotherapy was used as a policy for high grade lesions in the initial five years of the study (98 cases), but was omitted subsequently. RESULTS Extremity lesions fared more favourably compared to head and neck and torso lesions (p = 0.02) with respect to survival. Extremity and torso lesions had significantly better local control (p < 0.0001) than in the head and neck where local failure was a common cause of death. A multiple Cox regression analysis revealed that resection margins, local extension of tumor, age at diagnosis, and grade correlated with local relapse and distant relapse was also associated with local extension, high grade and in addition, large lesions. Size appeared especially predictive for distant failure, the most common cause of death. Distant failure was not influenced by the use of adjuvant chemotherapy. Patients treated for recurrence in this series had significantly worse survival due to increased distant failure despite similar local control to primary cases. CONCLUSION This series highlights the overall problem of distant failure in this disease. It also reaffirms the importance of obtaining local control both in the head and neck, where uncontrolled local disease is the major cause of death, and in general since local relapse appears to increase the risk of distant failure. It appears that the current staging systems should be reviewed in the light of the apparent effect of different prognostic factors.
