Benefit of Radiotherapy in Extraskeletal Myxoid Chondrosarcoma: A Propensity Score Weighted Population-based Analysis of the SEER Database.

Objectives: Extraskeletal myxoid chondrosarcoma (EMC) is a rare malignancy for which the role of radiotherapy is not well-defined. We examine the effect of external beam radiotherapy (EBRT) on cancer-specific survival (CSS) for patients with localized EMC, in a propensity score weighted, population-based analysis.

Materials And Methods: The Surveillance, Epidemiology, and End Results database (1973 to 2012) was queried for cases of localized EMC arising from soft connective tissues of the trunk and extremities treated with surgery and/or EBRT.

Pancreatic mucinous cystic neoplasm in a transgender patient.

Background: Cystic pancreatic lesions are increasingly more frequent detected clinical entities. Mucinous cystic neoplasm (MCN) is a hormone-related pancreatic tumor (HRTP) with a strong predominance in young and middle-aged females.

Case Presentation: Here, we present the case of a 31-year-old surgically transgendered female-to-male patient with a history of alcoholic pancreatitis, on chronic testosterone therapy.

Pseudotetraploid clone with structural chromosomal rearrangements in a chondromyxoid fibroma: a case report.

Chondromyxoid fibroma is a rare benign tumor accounting for 1-2% of primary bone tumors. Most of the patients are young males in the 2nd and 3rd decades of life. Metaphyses of long bones are predominantly affected.

Breast cancer cell surface annexin II induces cell migration and neoangiogenesis via tPA dependent plasmin generation.

Annexin II, an abundant phospholipids binding cell surface protein, binds tPA and functions as a regulator of fibrinolysis. Annexin II also mediates angiogenesis and enhances tumor growth and metastasis. However, the mechanism supporting this role is not known.

Angiogenesis-associated protein annexin II in breast cancer: selective expression in invasive breast cancer and contribution to tumor invasion and progression.

Many advanced human tumors including breast cancer overproduce plasmin that is known to promote angiogenesis and metastasis. The mechanism of this effect is poorly understood. Here we report that annexin II, an endothelial co-receptor for tPA (tissue-type plasminogen activator) and plasminogen, was undetectable in normal and hyperplastic ductal epithelial cells and ductal complexes.
