Background and Purpose: Limb sparing surgery and radiotherapy is the main treatment of patients harboring soft tissue sarcoma of the extremity. There is limited data regarding the prognostic impact of histologic response after pre-operative radiotherapy. Patients and Methods: Between 2010 and 2018, 123 patients were treated with a pre-operative radiotherapy for soft tissue sarcoma at Leon Berard Centre (Lyon, France) and were retrospectively reviewed. All patients received a dose of 50 Gy in 25 fractions. The histologic response has been analysed by considering the following factors: necrosis ≥ 90%, percentage of viable tumor cells ≤ 10% and fibrosis ≥ 10%. Overall survival (OS), local recurrence-free survival (LRFS), distant recurrence-free survival (DRFS) and event-free survival (EFS) were evaluated. Results: Median follow up was 33.2 months (range 2.3-128.1 months). Local recurrence occurred in 9 patients (7.5%) and 40 patients (33%) presented a distant recurrence. The 2 and 5-year OS was 84% and 63%. Histologic response factors (necrosis ≥ 90%, viable tumor cells ≤ 10% and fibrosis ≥ 10%) were not predictive in DRFS and EFS. In multivariate analysis, grade was the only significant prognostic factor for EFS P=0.0087. Among the 14 patients with ≤ 10% viable cells after irradiation 13 presented a metastatic evolution within 6 months. Conclusion: This study showed that current histological response evaluation based on necrosis, fibrosis and viable cells could not predict clinical outcomes after radiotherapy for extremity soft tissue sarcoma. A significant proportion of patients with a good response after pre-operative radiotherapy present a metastatic recurrence.

Therapeutic Concepts

Uniform conclusions about therapeutic concepts and survival time of bone and soft tissue sarcoma patients are difficult due to the heterogeneity of histological subtypes as well as the different responses to neoadjuvant therapy. The subject of this retrospective study was the analysis of tumour free survival, risk and prognostic factors of sarcoma patients treated by limb sparing techniques or amputation. We included 118 patients with soft tissue sarcoma of the extremities treated primarily or secondarily at our institution between 1990 and 2008 with a minimum follow-up of 12 months. Data about the tumour free survival time, operative techniques and potential prognostic factors were analysed. The tumour-specific and overall survival were significantly influenced by two factors: the grading and distant metastases present at time of diagnosis. Optimal multimodal therapeutic concepts at a specialized Cancer Center decreased the risk of local recurrence. The importance of optimal preoperative and surgical course concerning the oncological long term outcome was investigated. The decrease in local recurrence as a result of multimodal therapeutic concepts at a specialized Cancer Center was confirmed. To evaluate the individual prognosis of a patient, multiple factors have to be considered. Factors for a poor prognosis are primary metastasis, high-grade tumours and several histological entities (<em>e.g</em>. synovial sarcoma, not other specified).

Purpose. The influence of initial inadequate excision (IIE) of soft tissue sarcoma (STS) on local control and overall survival is not well established. It is generally believed that an IIE may have a negative impact on both, despite subsequent treatment by radical surgery and radiotherapy. However, data on local recurrence-free survival/overall survival are conflicting and there are no data on the effect of IIE on overall survival.Patients and methods. A retrospective analysis was made of 86 patients with soft tissue sarcoma of the extremities and trunk after an IIE had been performed due to inappropriate work-up. The minimal follow-up was 7 years. Specimens of the subsequent radical resection were evaluated for residual tumor, grade of tumor and complications of IIE. Endpoints were recurrence-free survival and overall survival.Results. Specimens of the subsequent radical resection showed residual tumor in 66 patients (77%). The most common complication after IIE was hematoma. In both univariate and multivariate analyses, grade II/III tumors and complications after IIE are significant negative prognostic factors for local recurrence-free survival (P= 0.008 andP= 0.002, respectively, in the Cox model). For this survival, three prognostic groups could be formed based on grade, or presence or absence of complications. Adjuvant radiotherapy did not change the rate of local recurrence-free survival. For overall survival, only tumor grade is a significant factor (log-rank test).Conclusion. This retrospective study shows that complications associated with an IIE have a significant negative effect on local control, but not on overall survival, because IIE is often the result of inappropriate work-up before surgery. For better diagnosis and therapy STS should be treated in specialized centers.

Our retrospective study analysed the long-term results of a conservative limb-preserving surgical strategy in 51 patients with soft-tissue sarcoma of the hand from a single institution. We assessed survival and prognostic factors, including the surgical margins. No transradial amputations were performed. Microscopically free resection margins were obtained in 45 of the patients. The remaining six patients had microscopically incomplete resection. Forty-four surviving patients had a median follow-up of 6.5 years (range 12–307), and one patient had no follow-up beyond 3 months following surgery. Among those patients, 29 had more than 5 years of follow-up. Five-year local-recurrence-free survival was 65%, metastasis-free survival was 84%, and disease-specific survival was 91%. Tumour size was predictive of all outcome parameters, but positive resection margins adversely affected local recurrence only. Survival was similar to the survival after a more radical surgical approach reported in the literature. Level of evidence: IV

Abstract Background This novel study compared the use of tumor necrosis factor (TNF)-alpha and melphalan-based isolated limb perfusion (TM-ILP) to the standard treatment of locally recurrent soft tissue extremity sarcoma. The aim was to assess whether TM-ILP positively influences the recurrence-free survival of locally recurrent high-grade soft tissue sarcoma (STS) of the extremities. Methods We retrospectively analyzed our clinical database for patients with STS. Variables were analyzed using chi-square test or Mann-Whitney rank-sum test. Furthermore, Kaplan-Meier survival plots were calculated and a proportional hazard regression model was developed. Results Out of 448 patients with extraabdominal STS treated between August 2012 and December 2015, 52 cases involving 47 patients had locally recurrent STS. Twenty-eight of these patients were treated with TM-ILP prior to surgical resection (TM-ILP-group), and 24 were treated with standard therapy (without TM-ILP). The 3-year recurrence-free survival for the TM-ILP-group was estimated at 75% (95% confidence interval (CI), 71.5–78.5). Local recurrence-free survival in the standard group was significantly lower (LRFS: 43.4%, 95% CI 38.7–48.1, p = 0.026). Multivariable analysis revealed resection with negative margins, lower number of previous recurrences, and TM-ILP as positive predictors for recurrence-free survival. Conclusions TM-ILP and consecutive resection of residual tumor with negative resection margins significantly improves local recurrence-free survival for patients with a first local recurrence of high-grade STS in the extremities.

The Impact

BackgroundUnplanned excision (UPE) of soft tissue sarcoma (STS) is often chosen in the early phase by general physicians without any radiological evaluation.PurposeThe present study aimed to evaluate the impact of UPE on the clinical outcomes of patients with STS of the trunk and extremity.Materials and MethodsPatients with STS of the trunk and extremity who underwent R0 resection between 1998 and 2016 were included and divided into the UPE and planned excision (PE) groups. Propensity score matching (PSM) was used to control the selection bias. The endpoints were disease-specific survival (DSS), local recurrence-free survival (LRFS), and metastasis-free survival (MFS).ResultsIn total, 458 patients (277 males, 181 females; median age: 43 years) were included: 329 (71.8%) in the PE group and 129 (28.2%) in the UPE group. The follow-up time ranged from 7.1 to 313.78 months, with a median of 112.18 months. UPE patients were more likely to have a smaller or superficial lesion and were more frequently administered adjuvant therapy. After PSM, compared with the PE group, the UPE group had a longer LRFS (P=0.015), but there was no difference between the two groups regarding DSS and MFS. Residual disease was observed in 77.5% of the re-resected specimens in the UPE group and was a risk factor for DSS (P = 0.046) and MFS (P = 0.029) but was not associated with local recurrence (LR) (P=0.475) or LRFS (P=0.334). Moreover, we found no difference in DSS, LRFS or MFS according to the interval from UPE to definitive resection.ConclusionSTS treated with UPE had distinct characteristics. Patients who undergo UPE followed by an additional wide R0 resection have similar oncological survival compared to patients who undergo an initial PE, although the high incidence of residual tumor in the UPE group leads to an unfavorable clinical course.

Effect Of Age

Purpose To examine the effect of age on the recurrence of soft tissue sarcoma in the extremities and trunk. Patients and Methods This was a multicenter study that included 2,385 patients with median age at surgery of 57 years. The end points considered were local recurrence and metastasis. Cox proportional hazards models were used to estimate hazard ratios across the age ranges with and without adjustment for known confounding factors. Results Older patients presented with tumors that were larger (P < .001) and of higher grade (P < .001). The proportion of positive margins increased significantly as patients age (P < .001), but radiation therapy was relatively underused in patients older than age 60 years. The 5-year cumulative incidences of local recurrence were 7.2% (95% CI, 4% to 11.7%) for patients age 30 years or younger and 12.9% (95% CI, 9.1% to 17.5%) for patients age 75 years or older. The corresponding 5-year cumulative incidences of metastasis were 17.5% (95% CI, 12.1% to 23.7%) and 33.9% (95% CI, 28.1% to 39.8%) for the same groups. Regression models showed that age was significantly associated with local recurrence (P < .001) and metastasis (P < .001) in nonadjusted models. After adjusting for imbalance in presentation and treatment variables, age remained significantly associated with local recurrence (P = .031) and metastasis (P = .019). Conclusion Older patients have worse outcomes because they tend to present with worse tumors and are treated less aggressively. However, there remained a significant increase in the risk of both local and systemic recurrence associated with increasing age that could not be explained by tumor or treatment characteristics.

Abstract BackgroundSoft tissue sarcoma（STS） is a malignant tumor of highly heterogeneous mesenchymal origin. STS has a biologic pattern and clinical transformation with localized invasive growth and susceptibility to hematogenous metastasis. Metastatic and recurrent soft tissue sarcoma may be treated by local therapeutic options, including surgery and radiation therapy. This study evaluated the safety and efficacy of SBRT for metastatic and recurrent soft tissue sarcoma.MethodsWe performed a retrospective analysis of 37 STS patients with 58 lesions treated with SBRT from 2009-2019 at our institution. We analyze the local control (LC), overall survival (OS), progression free survival (PFS) and toxicity rates of the patients.ResultThe median follow-up was 20 months（range 2 to 120 months）. One and two year LC rates were 75.3% and 55.2% [95% confidence interval (CI) 20–25 months]. Median OS was 24 months and the survival rates were 66.6%, 45% and 26.6% at 1, 2 and 3-year after SBRT. Median PFS were 11months (95% CI 8–18 months). No acute or chronic grade ≥ 3 toxicity was observed.ConclusionsIn patients with metastatic and recurrent STS, LC, OS and PFS were higher than expected. SBRT should be a proper treatment option for STS.
