This study explored psychological functioning and coping styles in adult patients with localized and metastatic extremity soft-tissue sarcoma (STS) from diagnosis through survivorship in a single expert sarcoma center in Canada. Our analyses were driven by three main goals: 1) to develop a better understanding of the affective responses and coping mechanisms in patients who face this rare illness, 2) to identify areas of psychological functioning in which patients with STS experience most difficulties, and 3) to describe how these areas could be best addressed in clinical settings. This descriptive qualitative study is a part of a larger mixed-methods study on health related quality of life (HRQoL) in adult patients with soft-tissue sarcoma treated between 2003 and 2018. Purposive sampling based on demographic and disease variables from all patients within a prospective database was utilized to ensure a representative patient population. Three formats of data collection were conducted in French and English, 2 online focus groups (total n=12), 2 in-person focus groups (total n=12), as well as individual semi-structured interviews (n=4). Data was analyzed using inductive thematic networks approach using the qualitative software N-Vivo 12. Codes were generated by 2 independent qualitative experts that captured key concepts referring to psychological functioning and coping mechanisms. Basic themes were clustered into organizing themes, which were later merged into a global theme. Attention was paid to deviant cases, and within-group dynamics during focus group discussion analysis. Any discrepancies or inconsistencies in coding were resolved in a consensus meeting. The final sample size was determined when data saturation was reached, and no new themes emerged. Our analyses of psychological well-being and functioning revealed three main themes, mood, anxiety, and body image concerns. Feelings of depression and low mood were prominent, coinciding with physical symptoms and limitations especially during the phase of treatment and recovery. Women were more likely to report emotional volatility, while men tended to report more preoccupation. Loss of control and independence, anxiety related to illness recurrence, uncertainty about the future and facing one's mortality significantly impacted quality of life. Furthermore, while patients were more concerned with limb functionality, disfigurement and self-consciousness featured prominently in the narrative. Four adaptive coping styles were observed, positive reframing and optimism, finding a purpose, being proactive, and using humor. Among the maladaptive strategies, we noted passive acceptance, and avoidance and denial. Psychological well-being is an important domain in the HRQoL of adult patients with extremity STS. Physicians and medical workers should encourage adaptive coping mechanisms such as positive reframing and optimism. Patients endorsing higher levels of psychological distress and maladaptive coping styles should be monitored for their well-being and multidisciplinary strategies employed to optimize psychological function and HRQoL

The patient's subjective experience of disease is an increasing focus in health care delivery. Health-related quality of life (HRQoL) is defined as a “functional effect of a medical condition and its consequent treatment”; it is both self-reported and multi-dimensional. While functional outcome is well researched among the soft tissue sarcoma (STS) population, few studies have focused on HRQoL, which gives a broader understanding of the psychological, somatic, social and physical toll of cancer and its treatment from the patient's viewpoint. The biologic and anatomic heterogeneity of sarcomas are considerable, just as the treatments are diverse, we surmise that the indicators of patient HRQoL differ and are not captured in existing generic HRQoL tools for cancer. The study objectives were to explore the domains of HRQoL and functioning in adult patients diagnosed with extremity STS from the patient's perspective from active care through survivorship through qualitative inquiry, so as to form the basis for the development of a patient-derived, sarcoma-specific, preference based HRQoL tool.

Study design is a sequential exploratory mixed methods study of patient experience in localized or metastatic adult extremity STS (2007 and 2017). The study was conducted at a high-volume sarcoma centre. Qualitative descriptive design was grounded in an integrated knowledge translation approach and aimed at identifying HRQoL domains through in-person and electronic focus groups, and individual semi-structured interviews in both English and French (N=28). The interview guide topics were selected based on existing knowledge about PROs and HRQoL life, including (a) impact of diagnosis on employment or acquisition of academic/vocational skills; (b) physical and psychological functioning; (c) symptom burden; (d) treatment preferences; (e) knowledge of and use of existing resources; (f) impact on family time and resources; and (g) overall experience. Data was analyzed using inductive thematic networks approach using the qualitative software N-Vivo 12. Codes were generated by 2 independent qualitative experts capturing key concepts of HRQoL that is impacted by STS. Basic themes were clustered into organizing themes, and merged into global domains. Attention was paid to deviant cases and within-group dynamics during focus group discussion analysis. Discrepancies or inconsistencies in coding were resolved in consensus meetings. Final sample size was determined when data saturation was reached and no new themes emerged. Qualitative reduction of identified items to reach a consensus framework was facilitated by a moderator during multi-disciplinary panel meetings comprised of sarcoma experts, patient partners, allied health staff and other stakeholders.

Twenty-nine patients with biopsy-proven localized or metastatic STS of the extremity participated (69% lower extremity STS; mean age 56 years, 25% with local recurrence, 21% metastatic, 18% amputation). Inductive thematic network analysis revealed five function-related domains HRQoL for patients with STS. The functional domains were mapped to the Wilson & Cleary Model and experience domains were mapped to the Picker Institute's Through Patient's Eyes model.

This is a critical step toward developing disease specific outcome measures. Patient-centered research is crucial to understanding the impact of surgery, adjuvant therapy and the associated complications for patients with extremity STS, and thereby improving the quality of care provision. This study offers a unique perspective on what domains and sub domains are most impactful on HRQoL and provides the basis for our on-going development of a disease-specific, preference-based HRQoL measure.

Aims. Treatment of high-grade limb bone sarcoma that invades a joint requires en bloc extra-articular excision. MRI can demonstrate joint invasion but is frequently inconclusive, and its predictive value is unknown. We evaluated the diagnostic accuracy of direct and indirect radiological signs of intra-articular tumour extension and the performance characteristics of MRI findings of intra-articular tumour extension. Methods. We performed a retrospective case-control study of patients who underwent extra-articular excision for sarcoma of the knee, hip, or shoulder from 1 June 2000 to 1 November 2020. Radiologists blinded to the pathology results evaluated preoperative MRI for three direct signs of joint invasion (capsular disruption, cortical breach, cartilage invasion) and indirect signs (e.g. joint effusion, synovial thickening). The discriminatory ability of MRI to detect intra-articular tumour extension was determined by receiver operating characteristic analysis. Results. Overall, 49 patients underwent extra-articular excision. The area under the curve (AUC) ranged from 0.65 to 0.76 for direct signs of joint invasion, and was 0.83 for all three combined. In all, 26 patients had only one to two direct signs of invasion, representing an equivocal result. In these patients, the AUC was 0.63 for joint effusion and 0.85 for synovial thickening. When direct signs and synovial thickening were combined, the AUC was 0.89. Conclusion. MRI provides excellent discrimination for determining intra-articular tumour extension when multiple direct signs of invasion are present. When MRI results are equivocal, assessment of synovial thickening increases MRI’s discriminatory ability to predict intra-articular joint extension. These results should be interpreted in the context of the study’s limitations. The inclusion of only extra-articular excisions enriched the sample for true positive cases. Direct signs likely varied with tumour histology and location. A larger, prospective study of periarticular bone sarcomas with spatial correlation of histological and radiological findings is needed to validate these results before their adoption in clinical practice.

Aim. To identify patient, tumour or treatment factors that influence outcome in patients with radiation induced sarcoma of bone. Method. A retrospective review of an oncology database supplemented by referral back to original records. Results. We identified 42 patients who presented to our Unit over a 25 year period with a new sarcoma of bone following previous radiotherapy. The age of the patients at presentation ranged from 10 to 84 years of age (mean: 17 years) and the time interval from previous radiotherapy ranged from 4 to 50 years (median: 14 yrs; mean: 17 years). The median dose of radiotherapy given had been 50 Gy but there was no correlation of radiation dose with time to development of sarcoma. The pelvis was the most common site for development of sarcoma (14 cases) but breast cancer was the most common primary tumour (8 cases). 9 of the patients had metastases at the time of diagnosis of the sarcoma. Osteosarcoma was the most common diagnosis (30). Treatment was by surgery and chemotherapy when indicated and 30 of the patients had treatment with curative intent. The survival rate was 41% at 5 years for those treated with curative intent but in those treated palliatively median survival was only 6 months and all had died by one year. The only factor found to be significant for survival was the ability to completely resect the tumour; thus, limb sarcomas had a better prognosis (66% survival at 5 years) than central ones (12%)(p=0.009). Conclusion. Radiation induced sarcoma is a rare complication of radiotherapy. Both surgical and oncological treatment is likely to be compromised by previous treatment the patient has received. Despite this 40% of patients will survive more than 5 years with aggressive modern treatment

Aims

Cell-free DNA (cfDNA) and circulating tumour DNA (ctDNA) are used for prognostication and monitoring in patients with carcinomas, but their utility is unclear in sarcomas. The objectives of this pilot study were to explore the prognostic significance of cfDNA and investigate whether tumour-specific alterations can be detected in the circulation of sarcoma patients.

Aims

The aim of this study was to assess orthopaedic oncologic patient morbidity resulting from COVID-19 related institutional delays and surgical shutdowns during the first wave of the pandemic in New York, USA.

Objectives: To investigate whether components of MSTS-87 (Pain, ROM, Strength, Stability, Deformity, Acceptance and Function) correlate with function as measured by TESS following endoprosthetic replacement (EPR) for patients with bone sarcoma. Methods: 255 patients with extremity bone sarcoma treated by resection & EPR were identified from a prospective database. From this group we investigated 111 patients with primary bone sarcoma with > 2 years follow up, evaluated by both MSTS-87 & TESS, no local recurrence, metastasis or major complication for at least 2 years prior to the follow-up. Upper extremity patients were excluded due to small numbers. We examined the influence of patient demographics and tumour characteristics on functional outcome scores. Correlation between MSTS-87 & TESS was performed using linear regression analysis. Results: Age, gender, tumour size, anatomical site, chemotherapy treatment and presence of pathological fracture did not significantly correlate with TESS. Linear regression analysis of MSTS-87 individual criteria and total score revealed that only pain, ROM and function helped explain the TESS score (p < 0.05) while strength, stability, deformity & acceptance had no significant effect on overall functional outcome. Conclusions: Of the seven MSTS-87 variables, only pain, ROM and function significantly correlate with overall functional outcome as measured by TESS following EPR for bone sarcoma. This suggests that patients with decreased strength, stability, deformity and acceptance as defined by MSTS-87 scores, may still adapt well with good overall functional outcomes

The December 2012 Trauma Roundup³⁶⁰ looks at: more is not always better, especially when its chemotherapy; new hope for skeletal metastasis; biopsy tracts; intra-operative imaging of sarcomas; curettage with adjuvant therapy; amputation and distal tibial osteosarcoma; and diaphyseal tibial tumours.

The February 2014 Oncology Roundup³⁶⁰ looks at: suspicious lesions; limb salvage in pelvic sarcomas; does infection affect oncological survival?; cancer patient pathways; radiological arthritis with cement augmentation in GCT; and post-chemotherapy increase in tumour volume as a predictor of poor prognosis.

Objectives

The clinical utility of routine cross sectional imaging of the abdomen and pelvis in the screening and surveillance of patients with primary soft-tissue sarcoma of the extremities for metastatic disease is controversial, based on its questionable yield paired with concerns regarding the risks of radiation exposure, cost, and morbidity resulting from false positive findings.
