Abstract

Tumor growth and angiogenesis are interdependent. Cyclooxygenase (COX) catalyzes the synthesis of prostaglandins (PGs) from arachidonic acid. Nonsteroidal antiinflammatory drugs (NSAIDs) inhibit COX-mediated synthesis of PGs. Although COX-1 is constitutively expressed in a wide range of tissues, COX-2 is cytokine inducible. Enhanced COX-2 expression has been attributed a key role in the development of inflammation and related processes observed in pathologically altered disease states. Two specific COX-2 inhibitors, namely, rofecoxib (Vioxx) and celecoxib (Celebrex), both oral agents and FDA approved, have been shown preclinically and clinically to have efficacy comparable to that of NSAIDs for relief of pain and inflammation in osteoarthritis, with decreased risk of gastrointestinal damage. Significant preclinical evidence strongly supports the potential role for these inhibitors for the treatment of cancer. On June 29, 2001, the Radiation Therapy Oncology Group (www.rtog.org), a National Cancer Institute-sponsored cooperative group, held a 1-day symposium focusing on the potential role of inhibitors of COX-2 in the treatment of cancer. This issue of the American Journal of Clinical Oncology contains the summary of those presentations.
