Mayo Clinic Laboratory and Pathology Research Roundup: January 2

The research roundup provides an overview of the past week’s research from Mayo Clinic Laboratories consultants, including featured abstracts and a complete list of published studies and reviews.
Featured Abstract
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.
