Abstract
INTRODUCTION The diagnosis process of soft tissue sarcomas of the musculoskeletal system (SPBAL) continues to be complex, with cases of unplanned excisions ("whoops" surgeries). This study evaluates the frequency of these type of procedures, trying to indentify patient characteristics, tumors, surgical treatment and final results. MATERIAL AND METHODS 131 patients treated surgically between October 2018 and December 2021 of a SPBAL were retrospectively reviewed. Patients with SPBAL located in the viscera, mediastinum, heart, retroperitoneum, peritoneum and genital tract were excluded. Differences between patients with planned and unplanned excisions were assessed with chi2 tests and a Cox multivariate regression model. RESULTS Unplanned excisions of SPBAL have taken place in 18% of the patients in our área, mainly in tumors of less than 5 cm and located superficial to the fascia. 29,2% of these patients did not have a previous imaging test. It has not been shown that a "whoops" surgery can lead to a decrease in survival or a higher rate of recurrences. CONCLUSIONS We recommend carrying out an imaging test always prior to the removal of any type of soft tissue tumor, as well as adherence to the referral guidelines to reference centers.

Abstract
BACKGROUND In soft tissue sarcomas, the oncological and functional outcomes between planned excision and unplanned excision with additional wide resection remains controversial. The purpose of this study is to determine the impact of unplanned excision on oncological and functional outcomes. METHODS A retrospective single-center study was performed. Patients with soft tissue sarcoma surgically treated in 2005-2019 were included in this study. A total of 120 patients consisting of planned excision (PE) group (n = 88), and unplanned excision (UE) group (n = 32) were included. Overall-survival (OS), local recurrence-free survival (LRFS), metastasis-free survival (MFS), disease-free survival (DFS), incidence rate of reconstructive surgery and musculoskeletal tumor society (MSTS) score were assessed. Propensity score matching method was used in statistical analysis. RESULTS The 5-year survival rate of OS, LRFS, MFS, and DFS did not differ between the PE and UE groups, however, rates of reconstructive surgery were higher in the UE group (PE: 48% vs. UE: 84%, p < 0.001). These results did not differ (PE: 41% vs. UE: 82%, p = 0.012) after propensity score matching was performed to align the backgrounds with difference in tumor size and depth. For MSTS score, the total score and "pain" and "emotional acceptance" scores were higher in the PE group before propensity score matching. The "pain" and "emotional acceptance" scores were higher in the PE group after propensity score matching also. CONCLUSIONS Unplanned excision did not deteriorate oncological outcomes, however unplanned excision lead to unnecessary reconstructive surgery. Unplanned excision adversely affected patient-reported outcomes without worsening pure functional outcomes.

Abstract
The surgical management of soft-tissue sarcoma has evolved significantly over the last two decades due to the routine use of adjunct therapies, with an increased focus on postoperative functional outcome. The literature suffers from methodological inconsistency and use of low quality outcome measures to assess an already heterogeneous population. This article aims to review the most frequently used subjective and objective methods of functional outcome assessment and highlight the current benefits and limitations of these.

Abstract
INTRODUCTION Timely recognition of soft tissue sarcomas (STS) remains challenging, potentially leading to unplanned excisions (also known as 'whoops procedures'). This population-based study charted the occurrence of unplanned excisions and identified associated patient, tumour, and treatment-related characteristics. Furthermore, it presents an overview of the outcomes and clinical management following an unplanned excision. METHODS From the Netherlands Cancer Registry (NCR) database, information was obtained on 2187 adult patients diagnosed with STS in 2016-2019 who underwent surgery. Tumours located in the mediastinum, heart or retroperitoneum were excluded, as well as incidental findings. Differences between patients with planned and unplanned excisions were assessed with chi-square tests and a multivariable logistic regression model. RESULTS Overall, unplanned excisions comprise 18.2% of all first operations for STS, with a quarter of them occurring outside a hospital. Within hospitals, the unplanned excision rate was 14.4%. Unplanned excisions were more often performed on younger patients, and tumours unsuspected of being STS prior to surgery were generally smaller (≤5 cm) and superficially located. Preoperative imaging was omitted more frequently in these cases. An unplanned excision more often resulted in positive margins, requiring re-excision. Patients who had an unplanned excision outside of a sarcoma centre were more often discussed at or referred to a sarcoma centre, particularly in case of residual tumour. DISCUSSION Potential improvement in preventing unplanned excisions may be achieved by better compliance to preoperative imaging and referral guidelines, and stimulating continuous awareness of STS among general surgeons, general practitioners and private practices.

Clin Transl Radiat Oncol 2021; 31:42-49. [PMID: 34622039 PMCID: PMC8479243 DOI: 10.1016/j.ctro.2021.08.008] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 08/10/2021] [Accepted: 08/24/2021] [Indexed: 11/13/2022] Open
Abstract
First to evaluate PROMIS for patients undergoing radiotherapy and surgery for sarcoma. Patients exhibited meaningful change in PROMIS scores throughout the treatment. Analyses show PROMIS scores were similar between pre- and post-operative radiotherapy. Wound complications were associated with increases in anxiety and decreases in function. These data should be considered when selecting ideal therapy.
Introduction Few recent studies have examined patient reported outcomes (PROs) during pre- or post-operative radiation therapy (RT) for soft tissue sarcoma (STS), and none have used PROMIS. This study aims to examine PROMIS scores across peri-operative time points for patients receiving pre- or post-operative RT. Methods Anxiety, depression, pain interference, and physical function PROMIS domains were collected at the pre-operative (1), immediate post-operative (2), and post-treatment completion (3) timepoints for patients undergoing surgery and either pre-operative or post-operative RT. Median scores were compared between groups using the Kruskal-Wallis test. The reliable change index was used to determine minimum important change in PROMIS scores and to compare scores between timepoints. Results 95 patients were included (19 pre-operative, 76 post-operative). Both groups had significant decreases in function during treatment. Patients with wound complications were more likely to have significant increases in anxiety (36.4% vs. 8.3%; p = 0.020) and decreases in physical function (57.1% vs. 16.2%; p = 0.011) independent of RT timing. Conclusions This study demonstrates minimum significant change thresholds to detect PROMIS changes in STS patients undergoing pre- and post-operative radiotherapy. As expected, more patients with pre-operative RT than post-operative RT had wound complications (p = 0.06), but patients with complications in both groups had worse anxiety and function at the completion of treatment compared with those that did not. The association of wound complications with worse anxiety and physical function at completion of treatment should be considered when making individualized treatment recommendations regarding the timing of RT.

Unravelling the heterogeneity of soft tissue and bone sarcoma patients' health-related quality of life: a systematic literature review with focus on tumour location. ESMO Open 2021; 5:e000914. [PMID: 33082266 PMCID: PMC7577059 DOI: 10.1136/esmoopen-2020-000914] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 08/17/2020] [Accepted: 08/18/2020] [Indexed: 12/18/2022] Open
Abstract
Patients with sarcoma experience many physical and psychological symptoms, adversely affecting their health-related quality of life (HRQoL). HRQoL assessment is challenging due to the diversity of the disease. This review aims to unravel the heterogeneity of HRQoL of patients with sarcoma with regard to tumour location and to summarise the used measures in research. English-language literature from four databases published between January 2000 and April 2019 was reviewed. Studies that described adult sarcoma HRQoL outcomes were included and classified according to primary sarcoma location. Eighty-seven articles met the inclusion criteria covering sarcoma of the extremities (n=35), pelvis and axial skeleton (n=9), pelvis and extremities (n=5), head and neck (n=4), retroperitoneum (n=2) and multiple sarcoma locations (n=33), respectively. Urogenital and thoracic sarcoma were lacking. Fifty-four different questionnaires were used, most often cancer-generic or generic HRQoL questionnaires. Patients with sarcoma reported lower HRQoL than the general population. Distinctive patterns of HRQoL outcomes according to tumour location regarding symptoms, physical functioning, disability and psychosocial well-being were identified. In metastatic sarcoma, mostly constitutional symptoms were present. To comprehensively assess HRQoL, a sarcoma-specific measurement strategy should be developed and used covering the heterogeneity of sarcoma including location-specific issues to improve personalised HRQoL assessment in future research and clinical practice.

Abstract
Functional assessment of patients with osteosarcoma may yield unique insights into the guide and advance treatment. A range of patient-reported outcomes has been validated, including general health and condition-specific measures as well as computer adaptive testing. Health state utility measures, which facilitate comparative-effectiveness research, are also available. Beyond these surveys, and laboratory-dependent gait analyses, is the potential for real-world evaluation through research-oriented and consumer-oriented accelerometers. Initial studies have shown promising validity of these activity trackers and may also have implications for traditional oncologic outcomes.

Abstract
BACKGROUND Soft tissue sarcomas (STS) are a rare and heterogeneous group of malignant tumors that arise from the mesenchymal tissue. STS can form anywhere in the human body, with the extremities being preferred sites of predilection. TREATMENT A fundamental pillar of treatment is the surgical resection of soft tissue sarcomas. The goal is always an R0 resection with a safety margin. There is no consensus in the literature about the desired tumor-free resection margin. The decisive factors for these resection margins are histopathology, presence of anatomical barriers (capsule, tendon, fascia, cartilage, periosteum) and possibilities of (neo-) adjuvant therapy. DISCUSSION References in the literature support the role of resection margins as a predictor of local recurrence. Regarding the role of resection margins in overall survival, available data is divergent. There are known prognostic factors that influence overall survival, such as histological subtype, tumor size, tumor grading, and presence of metastases. So far, several studies have attempted to quantify the margins of resection, but no consensus has been reached, and debates are ongoing. When analyzing all the results of the data in the literature, it seems appropriate to aim for a negative resection margin >1 mm including an anatomical border structure, if possible.
