* Combined zoledronic acid and meloxicam reduced bone loss and tumour growth in an orthotopic mouse model of bone-invasive oral squamous cell carcinoma. |
- Oral squamous cell carcinoma (OSCC) is common in cats and humans and invades oral bone. We hypothesized that the cyclooxygenase (COX)-2 inhibitor, meloxicam, with the bisphosphonate, zoledronic acid (ZOL), would inhibit tumour growth, osteolysis and invasion in feline OSCC xenografts in mice. Human and feline OSCC cell lines expressed COX-1 and COX-2 and the SCCF2 cells had increased COX-2 mRNA expression with bone conditioned medium. Luciferase-expressing feline SCCF2Luc cells were injected beneath the perimaxillary gingiva and mice were treated with 0.1 mg kg(-1) ZOL twice weekly, 0.3 mg kg(-1) meloxicam daily, combined ZOL and meloxicam, or vehicle. ZOL inhibited osteoclastic bone resorption at the tumour-bone interface. Meloxicam was more effective than ZOL at reducing xenograft growth but did not affect osteoclastic bone resorption. Although a synergistic effect of combined ZOL and meloxicam was not observed, combination therapy was well-tolerated and may be useful in the clinical management of bone-invasive feline OSCC. |
