Does compartmental resection really impact retroperitoneal soft tissue sarcomas? A retrospective analysis from a Single Referral Center.

Background: The treatment of choice for retroperitoneal soft tissue sarcomas (RPS) is surgical resection; the outcomes with more radical surgeries, notably compartmental resection, remains a subject of debate. Arguments against it, include the complexity of the technique and high morbidity.

Materials And Methods: A retrospective analysis of cases treated in a single center from January 2010 to December 2019 is presented.

Neutrophil-to-Lymphocyte ratio as a prognostic biomarker in extremities undifferentiated pleomorphic sarcoma.

Background: Neutrophil-to-lymphocyte ratio (NLR) in peripheral blood reflects the balance between systemic inflammation and immunity and has been reported as a prognostic biomarker in many neoplastic diseases, but its role in sarcomas has been poorly investigated. In this paper we analyzed the prognostic role of the neutrophil to lymphocyte ratio (NLR) in extremity undifferentiated pleomorphic sarcoma (eUPS).

Materials And Methods: We performed an observational, retrospective study including all eUPS cases treated at the National Institute of Cancer in Mexico City from January 2000 to December 2018.

Frozen abdomen complicated with midline heterotopic peritoneal ossification: case report.

Background: Heterotopic ossification consists in abnormal differentiation of mesenchymal cells into osteoblastic cells, which may occur in the abdominal cavity.

Case Report: A 54-year-old male who presents with small bowel obstruction, performing a laparotomy, adhesiolysis, and managed with an open abdomen with Bogota bag; the abdominal wall was closed on the 5 post-operative day. Due to recurrent symptoms of intestinal obstruction, he required a re-laparotomy after 14 days, finding a frozen abdomen with midline calcified peritoneum.
