Musculoskeletal Tumor Society Member Survey: Intra-Operative Peripheral Margins in Soft Tissue Sarcoma.

Background And Objectives: Routine intraoperative peripheral margin sampling is often employed by musculoskeletal surgical oncologists. Several recommendations exist regarding this practice pattern. It is unknown what the practice patterns of Musculoskeletal Tumor Society (MSTS) members are.

Intraoperative Peripheral Frozen Margin Assessment in Soft Tissue Sarcoma.

Background/objectives: Intraoperative peripheral margin sampling in soft tissue sarcoma (STS) is a routine practice among musculoskeletal oncologists. Practice patterns are variable, and evidence to support it is lacking. Rates of peripheral margin sampling at our institution were analyzed in addition to its clinical utility and cost-effectiveness.

Visceral fat area and subcutaneous fat area as measures of body composition in soft tissue sarcoma.

Background And Objectives: Soft tissue sarcomas (STS) are a heterogenous group of malignancies of mesenchymal origin. Given recent data linking obesity as well as the pattern of fat distribution with cancer outcomes, we sought to investigate the association of visceral fat area (VFA) and subcutaneous fat area (SFA) with oncologic outcomes in patients with STS undergoing surgery.

Methods: We analyzed data from 88 patients with STS diagnosed from 2008 to 2022.

Systemic immunostimulation induces glucocorticoid-mediated thymic involution succeeded by rebound hyperplasia which is impaired in aged recipients.

The thymus is the central organ involved with T-cell development and the production of naïve T cells. During normal aging, the thymus undergoes marked involution, reducing naïve T-cell output and resulting in a predominance of long-lived memory T cells in the periphery. Outside of aging, systemic stress responses that induce corticosteroids (CS), or other insults such as radiation exposure, induce thymocyte apoptosis, resulting in a transient acute thymic involution with subsequent recovery occurring after cessation of the stimulus.
