Objective: To investigate the effects of a selective cyclooxygenase (COX)-2 inhibitor on endometriosis xenografts in immunodeficient mice. Design: Prospective placebo-controlled study. Setting: An academic facility at a Japanese university graduate school of medicine. Patient(s): Eight human ovarian endometriomas from seven patients. Animal(s): Twenty-three female severe combined immunodeficiency (SCID) mice. Intervention(s): Human ovarian endometriomas were implantred into the peritonea of SCID mice. Vehicle alone or NS398 (a selective COX-2 inhibitor, 10 mg/kg of weight per day) were administered orally for 56 days after implantation. Mice were killed in the 56th day. Main Outcome Measure(s): change in explants size and immunohistochemical analyses to evaluating the proliferation index, apoptosis index, microvessel density, and labeling index assesing vascular endothelial growth factor and COX-2 expression by the endometriotic lesion. Result(s): NS398 significantly decreased implant size in comparison to vehicle alone (NS398 [medians, with range in brackets]: 22.0% [19.0%-36.7%] vs. vehicle: 41.2% [31.0%-55.3%], P < .01). microvessel density (85.3 per mm(2) [53.9-157.0 per mm(2)] vs. 121.8 per mm(2) [97.2-259.6 per mm(2)], P = .02) and the vascular endothelial growth factor (0.4 [0-1.1] vs. 0.6[0.5-2.1], P = .03) and COX-2 (0.4[0.4-0.5] vs. 0.6 [0.4-0.8], P = .03) labeling indices in stromal cells were significantly lower in the NS398 group than in the vehicle group. There were no differences in the proliferation or apoptosis between the two groups. Conclusion(s): Selective COX-2 inhibitors decreased the size of implants and effectively treaded endometriosis.
