Effects of Red Blood Cell Transfusions on Distant Metastases of Oral Squamous Cell Carcinomas.

There is no consensus on the effect of red blood cell (RBC) transfusions on patients with oral squamous cell carcinoma (OSCC). The aim of this study was to investigate the association between RBC administration and the occurrence of distant metastases (M+) after surgical treatment of OSCC. All medical records of patients who underwent primary surgery for OSCC in our department (2003-2019) were analyzed retrospectively ( = 609).
