Risk factors for invasive cervical cancer in Latino women

Most invasive cervical cancer research in the United States has been conducted on non-Latino-White (NLW) and African-American women. Incidence, mortality, stage at diagnosis and survival indicators for invasive cervical cancer in Latino women in California are compared to NLW and African-American women. A model is presented which depicts structural, behavioral, genetic and biological risk factors for invasive cervical cancer. A literature review of risk factors and their association with invasive cervical cancer was conducted using MEDLINE and PsychINFO databases to determine if ethnic differences in risk factors explain observed differences in morbidity and mortality. Latino women experience a significantly higher incidence and mortality associated with invasive cervical cancer than NLW women. The review of risk factors found that rate differences of cervical cancer screening, early detection and human papilloma virus (HPV) type-specific infection explain much of the disparity in disease burden. Further research must clarify if ethnic differences exist in risk factors associated with ethnic variation in HPV-type prevalence in both cases and their sexual partners, in host immune responses, and multiparity.
