Cervical cancer, caused by the human papillomavirus (HPV), is the only cancer that is almost preventable through regular screening. In high-resource, as in low-resource and middle-resource countries, women hit by the AIDS epidemic have a high prevalence of infection with HPV and related disease, including cervical cancer. The question whether cervical screening, which helped to reduce dramatically cervical cancer rates through the detection of precancerous lesions in the general population, is as efficient in the setting of HIV is still debated.
The risk for cervical cancer remained high and stable during the last decade in HIV-infected women, and incidence did not decrease with improving CD4 cell counts in women receiving antiviral therapy. Optimal methods to improve both the sensitivity and the specificity of cervical cancer screening are currently evaluated. The use of HPV DNA tests in primary screening endorsed in the general population may be less specific in immunocompromised women and might thus not be as efficient on screening. HPV vaccines, recently available, have no therapeutic effect and might thus not be very useful in preventing cervical cancer in a population highly infected with multiple and persistent HPV.
Cervical cancer prevention remains an important goal in HIV-infected women and specific guidelines are warranted for this increasing population.
由人乳头瘤病毒(HPV)引起的宫颈癌是唯一一种几乎可通过定期筛查预防的癌症。在高资源国家以及低资源和中等资源国家,受艾滋病流行影响的女性中HPV感染及相关疾病(包括宫颈癌)的患病率都很高。通过在普通人群中检测癌前病变从而大幅降低宫颈癌发病率的宫颈筛查,在HIV感染者中是否同样有效,这一问题仍存在争议。
在过去十年中,HIV感染女性患宫颈癌的风险一直居高不下且保持稳定,接受抗病毒治疗的女性中,宫颈癌发病率并未随CD4细胞计数的改善而下降。目前正在评估提高宫颈癌筛查敏感性和特异性的最佳方法。在普通人群中认可的HPV DNA检测用于初筛,在免疫功能低下的女性中可能特异性较低,因此在筛查中可能效果不佳。最近可用的HPV疫苗没有治疗作用,因此在预防多重和持续性HPV高度感染人群的宫颈癌方面可能不太有用。
预防宫颈癌仍然是HIV感染女性的一个重要目标,对于这一不断增加的人群,需要有特定的指导方针。
