Parecoxib suppressed tumorigenicity in vivo. A Tumor formation in nude mice after 5 weeks. 1.5 × 10⁷ KYSE30 cells were injected into the right shoulder blade of nude mice. Parecoxib (0.3 mg/kg) or equal volume of normal saline (the blank group) was injected into the enterocoelia every 3 days after tumor cell inoculation. B Tumor tissues were resected from nude mice at 5 weeks post-inoculation
