The number of deaths from cervical cancer in the United States has decreased substantially since the implementation of widespread cervical cancer screening and has declined from 2.8 to 2.3 deaths per 100 000 women from 2000 to 2015.
To update the US Preventive Services Task Force (USPSTF) 2012 recommendation on screening for cervical cancer.
The USPSTF reviewed the evidence on screening for cervical cancer, with a focus on clinical trials and cohort studies that evaluated screening with high-risk human papillomavirus (hrHPV) testing alone or hrHPV and cytology together (cotesting) compared with cervical cytology alone. The USPSTF also commissioned a decision analysis model to evaluate the age at which to begin and end screening, the optimal interval for screening, the effectiveness of different screening strategies, and related benefits and harms of different screening strategies.
Screening with cervical cytology alone, primary hrHPV testing alone, or cotesting can detect high-grade precancerous cervical lesions and cervical cancer. Screening women aged 21 to 65 years substantially reduces cervical cancer incidence and mortality. The harms of screening for cervical cancer in women aged 30 to 65 years are moderate. The USPSTF concludes with high certainty that the benefits of screening every 3 years with cytology alone in women aged 21 to 29 years substantially outweigh the harms. The USPSTF concludes with high certainty that the benefits of screening every 3 years with cytology alone, every 5 years with hrHPV testing alone, or every 5 years with both tests (cotesting) in women aged 30 to 65 years outweigh the harms. Screening women older than 65 years who have had adequate prior screening and women younger than 21 years does not provide significant benefit. Screening women who have had a hysterectomy with removal of the cervix for indications other than a high-grade precancerous lesion or cervical cancer provides no benefit. The USPSTF concludes with moderate to high certainty that screening women older than 65 years who have had adequate prior screening and are not otherwise at high risk for cervical cancer, screening women younger than 21 years, and screening women who have had a hysterectomy with removal of the cervix for indications other than a high-grade precancerous lesion or cervical cancer does not result in a positive net benefit.
The USPSTF recommends screening for cervical cancer every 3 years with cervical cytology alone in women aged 21 to 29 years. (A recommendation) The USPSTF recommends screening every 3 years with cervical cytology alone, every 5 years with hrHPV testing alone, or every 5 years with hrHPV testing in combination with cytology (cotesting) in women aged 30 to 65 years. (A recommendation) The USPSTF recommends against screening for cervical cancer in women younger than 21 years. (D recommendation) The USPSTF recommends against screening for cervical cancer in women older than 65 years who have had adequate prior screening and are not otherwise at high risk for cervical cancer. (D recommendation) The USPSTF recommends against screening for cervical cancer in women who have had a hysterectomy with removal of the cervix and do not have a history of a high-grade precancerous lesion or cervical cancer.

自美国广泛实施宫颈癌筛查以来,美国宫颈癌死亡人数已大幅下降,从 2000 年至 2015 年,每 10 万名女性中死于宫颈癌的人数从 2.8 人下降至 2.3 人。
更新美国预防服务工作组(USPSTF)2012 年关于宫颈癌筛查的建议。
USPSTF 审查了宫颈癌筛查的证据,重点是临床试验和队列研究,评估了单独使用高危型人乳头瘤病毒(hrHPV)检测或 hrHPV 和细胞学联合检测(联合检测)与单独细胞学筛查相比的效果。USPSTF 还委托进行了一项决策分析模型,以评估开始和结束筛查的年龄、筛查的最佳间隔、不同筛查策略的有效性以及不同筛查策略的相关益处和危害。
单独使用细胞学筛查、单独进行原发性 hrHPV 检测或联合检测都可以检测出高级别癌前宫颈病变和宫颈癌。对 21 至 65 岁的女性进行筛查可大大降低宫颈癌的发病率和死亡率。对 30 至 65 岁的女性进行宫颈癌筛查的危害中等。USPSTF 非常肯定地得出结论,对 21 至 29 岁的女性每 3 年进行细胞学筛查,对每 3 年进行细胞学筛查的益处大大超过了危害。USPSTF 非常肯定地得出结论,对 30 至 65 岁的女性每 3 年进行细胞学筛查、每 5 年进行 hrHPV 检测或每 5 年进行联合检测(联合检测)的益处超过了危害。对 65 岁以上有足够先前筛查且无宫颈癌高危因素的女性以及对 21 岁以下的女性进行筛查没有显著益处。对因高级别癌前病变或宫颈癌以外的指征而接受子宫切除术且已切除子宫颈的女性进行筛查没有益处。USPSTF 非常肯定地得出结论,对 65 岁以上有足够先前筛查且无宫颈癌高危因素的女性、对 21 岁以下的女性以及对因高级别癌前病变或宫颈癌以外的指征而接受子宫切除术且已切除子宫颈的女性进行筛查不会带来净收益。
USPSTF 建议对 21 至 29 岁的女性每 3 年进行一次单独的宫颈细胞学筛查。(A 级推荐)USPSTF 建议对 30 至 65 岁的女性每 3 年进行一次单独的宫颈细胞学筛查、每 5 年进行一次单独的 hrHPV 检测或每 5 年进行一次 hrHPV 检测联合细胞学检测(联合检测)。(A 级推荐)USPSTF 建议不对 21 岁以下的女性进行宫颈癌筛查。(D 级推荐)USPSTF 建议不对有足够先前筛查且无宫颈癌高危因素的 65 岁以上女性进行宫颈癌筛查。(D 级推荐)USPSTF 建议不对已接受子宫切除术且未患有高级别癌前病变或宫颈癌的女性进行宫颈癌筛查。(D 级推荐)
