Impaired social functioning in adolescent and young adult sarcoma survivors: Prevalence and risk factors.

BACKGROUND: Sarcomas account for almost 11% of all cancers in adolescents and young adults (AYAs; 18-39 years). AYAs are increasingly recognized as a distinct oncological age group with its own psychosocial challenges and biological characteristics. Social functioning has been shown to be one of the most severely affected domains of health-related quality of life in AYA cancer survivors. This study aims to identify AYA sarcoma survivors with impaired social functioning (ISF) and determine clinical and psychosocial factors associated with ISF. METHODS: AYAs from the population-based cross-sectional sarcoma survivorship study (SURVSARC) were included (n = 176). ISF was determined according to the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 social functioning scale, and age- and sex-matched norm data were used as reference. RESULTS: The median time since diagnosis was 6.2 years (range, 1.8-11.2). More than one-quarter (28%) of AYA sarcoma survivors experienced ISF. Older age, higher tumor stage, comorbidities, lower experienced social support, uncertainty in relationships, feeling less attractive, sexual inactivity, unemployment, and financial difficulties were associated with ISF. In a multivariable analysis, unemployment (OR, 3.719; 95% CI, 1.261-10.967) and having to make lifestyle changes because of financial problems caused by one's physical condition or medical treatment (OR, 3.394; 95% CI, 1.118-10.300) were associated with ISF; better experienced social support was associated with non-ISF (OR, 0.739; 95% CI, 0.570-0.957). CONCLUSION: More than one-quarter of AYA sarcoma survivors experience ISF long after diagnosis. These results emphasize the importance of follow-up care that is not only disease-oriented but also focuses on the psychological and social domains.

EWSR1::POU2AF3(COLCA2) Sarcoma: An Aggressive, Polyphenotypic Sarcoma With a Head and Neck Predilection.

EWSR1::POU2AF3 (COLCA2) sarcomas are a recently identified group of undifferentiated round/spindle cell neoplasms with a predilection for the head and neck region. Herein, we report our experience with 8 cases, occurring in 5 men and 3 women (age range, 37-74 years; median, 60 years). Tumors involved the head/neck (4 cases), and one each the thigh, thoracic wall, fibula, and lung. Seven patients received multimodal therapy; 1 patient was treated only with surgery. Clinical follow-up (8 patients; range, 4-122 months; median, 32 months) showed 5 patients with metastases (often multifocal, with a latency ranging from 7 to 119 months), and 3 of them also with local recurrence. The median local recurrence-free and metastasis-free survival rates were 24 months and 29 months, respectively. Of the 8 patients, 1 died of an unknown cause, 4 were alive with metastatic disease, 1 was alive with unresectable local disease, and 2 were without disease. The tumors were composed of 2 morphologic subgroups: (1) relatively bland tumors consisting of spindled to stellate cells with varying cellularity and fibromyxoid stroma (2 cases) and (2) overtly malignant tumors composed of nests of "neuroendocrine-appearing" round cells surrounded by spindled cells (6 cases). Individual cases in the second group showed glandular, osteogenic, or rhabdomyoblastic differentiation. Immunohistochemical results included CD56 (4/4 cases), GFAP (5/8), SATB2 (4/6), keratin (AE1/AE3) (5/8), and S100 protein (4/7). RNA sequencing identified EWSR1::POU2AF3 gene fusion in all cases. EWSR1 gene rearrangement was confirmed by fluorescence in situ hybridization in 5 cases. Our findings confirm the head/neck predilection and aggressive clinical behavior of EWSR1::POU2AF3 sarcomas and widen the morphologic spectrum of these rare lesions to include relatively bland spindle cell tumors and tumors with divergent differentiation.

Serum high-mobility group box-1 levels are positively associated with micro- and macroalbuminuria but not with cardiovascular disease in type 1 diabetes: the EURODIAB Prospective Complications Study.

CONTEXT AND OBJECTIVE: High-mobility group box-1 (HMGB1) is a pro-inflammatory cytokine that may contribute to the pathogenesis of micro- and macrovascular complications commonly observed in diabetes. We investigated whether HMGB1 is associated with: i) markers of low-grade inflammation (LGI) and endothelial dysfunction (ED) and pulse pressure (PP, a marker of arterial stiffness); ii) prevalent nephropathy, retinopathy and cardiovascular disease (CVD) in type 1 diabetes; and iii) the potential mediating roles of LGI, ED and PP therein. DESIGN AND METHODS: This was a cross-sectional nested case-control study of 463 patients (226 women; mean age 40±10 years) with type 1 diabetes from the EURODIAB Prospective Complications Study. We used linear and binary or multinomial logistic regression analyses adjusted for traditional risk factors. RESULTS: Serum Ln-HMGB1 levels were positively associated with LGI and ED (standardised ß=0.07 (95% confidence interval (CI): 0.02-0.12) and ß=0.08 (95% CI: 0.02-0.14) respectively), but not with PP. Higher Ln-HMGB1 (per unit) was associated with greater odds of micro- and macroalbuminuria: odds ratio (OR)=1.24 (95% CI: 0.90-1.71) and OR=1.61 (95% CI: 1.15-2.25) respectively, P for trend=0.004. Further adjustments for LGI or ED did not attenuate these associations. No such associations were found between Ln-HMGB1 and estimated glomerular filtration rate (eGFR), retinopathy or CVD, however. CONCLUSIONS: In type 1 diabetes, higher serum HMGB1 levels are associated with greater prevalence and severity of albuminuria, though not with eGFR, retinopathy and CVD. Prospective studies are needed to clarify the causal role of HMGB1, if any, in the pathogenesis of vascular complications in type 1 diabetes.

Higher plasma soluble Receptor for Advanced Glycation End Products (sRAGE) levels are associated with incident cardiovascular disease and all-cause mortality in type 1 diabetes: a 12-year follow-up study.

OBJECTIVE: To investigate the associations of plasma levels of soluble receptor for advanced glycation end products (sRAGE) with incident cardiovascular disease (CVD) and all-cause mortality in type 1 diabetes and the extent to which any such associations could be explained by endothelial and renal dysfunction, low-grade inflammation, arterial stiffness, and advanced glycation end products (AGEs). RESEARCH DESIGN AND METHODS: We prospectively followed 169 individuals with diabetic nephropathy and 170 individuals with persistent normoalbuminuria who were free of CVD at study entry and in whom levels of sRAGE and other biomarkers were measured at baseline. The median follow-up duration was 12.3 years (7.6-12.5). RESULTS: The incidence of fatal and nonfatal CVD and all-cause mortality increased with higher baseline levels of log-transformed sRAGE (Ln-sRAGE) independently of other CVD risk factors: hazard ratio (HR) 1.90 (95% CI 1.13-3.21) and 2.12 (1.26-3.57) per 1-unit increase in Ln-sRAGE, respectively. Adjustments for estimated glomerular filtration rate (eGFR(MDRD)), but not or to a smaller extent for markers of endothelial dysfunction, low-grade inflammation, arterial stiffness, and AGEs, attenuated these associations to HR 1.59 (95% CI 0.91-2.77) for fatal and nonfatal CVD events and to 1.90 (1.09-3.31) for all-cause mortality. In addition, in patients with nephropathy, the rate of decline of GFR was 1.38 ml/min/1.73 m(2) per year greater per 1-unit increase of Ln-sRAGE at baseline (P = 0.036). CONCLUSIONS: Higher levels of sRAGE are associated with incident fatal and nonfatal CVD and all-cause mortality in individuals with type 1 diabetes. sRAGE-associated renal dysfunction may partially explain this association.
