PTGS2 and ovarian cancer: The analysis of COX-2 expression in ovarian cancer tissues before and after carboplatin/paclitaxel treatment in patients submitted to exploratory laparotomy and interval debulking surgery after successful neoadjuvant treatment, would be helpful in order to assess whether this regimen can modulate COX-2 expression in vivo, as very recently reported by Altorki et al. [37].
