The glucocorticoid dexamethasone is frequently used as a co-treatment in cytotoxic cancer therapy, e.g. to prevent nausea, to protect normal tissue or for other reasons. While the potent pro-apoptotic properties and supportive effects of glucocorticoids to tumour therapy in lymphoid cells are well studied, the impact on the cytotoxic treatment of ovarian carcinoma is unknown. We tested apoptosis-induction, viability, tumour growth and protein expression using established cell lines, primary cell lines freshly isolated from patient material and a xenograft on nude mice. We found a general induction of resistance toward cytotoxic therapy by DEX-co-treatment in most of the examined ovarian cancer cells treated in vitro, ex vivo or in vivo. Resistance occurred independently of cell density and was found at peak plasma levels of dexamethasone and below. Mechanistically, the dexamethasone-induced expression of survival genes may be involved in the resistance. These data show that glucocorticoid-induced resistance is common in ovarian carcinomas implicating that the use of glucocorticoids may be harmful for cancer patients.

Postoperative pain is a major problem, especially in orthopedic surgery. Our data suggest suboptimal pain management after total knee arthroplasty. This study evaluated a sufentanil sublingual tablet system (Zalviso) to optimize postoperative pain treatment. This retrospective, single-center, cohort study was conducted between January 2017 and September 2017. Zalviso as standard treatment was compared with a cohort receiving oxycodone (Oxy) immediate release and Oxy extended release and another receiving Oxy immediate release, Oxy extended release, and dexamethasone (Dexa + Oxy). The primary end point, pain intensity, was assessed on a numeric rating scale (NRS). Highest, lowest, and number of NRS scores >7 were collected. Secondary end points included length of hospital stay, nausea, and mobilization on the day of surgery. Patients receiving Dexa + Oxy had a lower lowest-pain intensity on day 0 (median 0, IQR 0-0) when compared to patients receiving Oxy (median 2, IQR 0-3; P<0.0001) or Zalviso (median 2, IQR 0-4; P<0.0001). No differences were observed on day 1 or 2. No differences were observed in highest pain score or number of patients reporting NRS scores > 7. Patients treated with Dexa + Oxy or Zalviso were discharged earlier compared to patients treated with Oxy (P<0.001). Patients treated with Zalviso experienced more nausea compared to other groups on day 0 and day 1 (P<0.001). Patients treated with Dexa + Oxy had a higher percentage of mobilization on the day of surgery compared to Oxy and Zalviso (P<0.001). In conclusion, Zalviso did not improve postoperative pain management in patients undergoing total knee arthroplasty and increased nausea.
