Cervical cancer is the second most common cancer in the female population worldwide, and human papillomavirus (HPV) DNA has been isolated from more than 90% of these carcinomas. Immunoregulatory/antitumour mechanisms include cytokines that interfere directly with HPV harbouring cells. Among these cytokines, tumour necrosis factor (TNF) is released by HPV infected cells and inhibits the growth of transformed cell lines.¹

TNF is a proinflammatory/antitumour cytokine that is indispensable to the inflammatory response. The TNF locus contains several polymorphic areas, including five microsatellite markers—a, b, c, d, and e—which contain 14, 7, 2, 7, and 3 alleles, respectively. These microsatellites are associated with different degrees of TNF secretion, and are related to a greater susceptibility to developing autoimmune and infectious diseases. A recent study reported several associations between TNF microsatellites and cancer, among other diseases.² However, up to now, the association of these markers with HPV and the progression to . . .
