Serologic answer to the papillomavirus oncogenic capsid types 16, 18, 31, 33, 39, 58 and 59 in Colombian women with cervix cancer

The carcinoma of the uterine cervix is the first cause of cancer mortality among young Colombian women. An etiological association between infection with high risk HPV and cervical cancer has been demonstrated. L1 proteins from HPV have the ability to assemble into virus-like particles (VLP) numerous serologic studies using HPV16 or HPV18 VLP have shown that infection with genital HPV is followed by a serologic immune response to viral capsid proteins. Our results confirm (i) the high rate of HPV infections in Colombia, both in cervical cancer patients and in the general population, and the particularly high rate of infections due to HPV 31 and 58; and (ii) the validity of anti-VLP antibodies as markers of present or past infections. The simultaneous appearance or disappearance of antibodies against multiple HPV VLP suggests that the antibodies detected by ELISA are not always type-specific
