半个世纪以前,美国妇女死于宫颈癌者多于其他任何肿瘤,随后若干年,宫颈癌死亡率明显下降,当前宫颈癌引起死亡在妇女癌患者中占第五位。浸润癌发病率减少,而宫颈上皮内新生物检出明显增加。美国癌协会1979年估计有16,000名妇女诊断为浸润癌,但确定原位癌者在45,000名以上。这种变化,至少部分由于巴氏涂片广泛使用于普查而发现上皮内新生物。但在七十年代美国估计仅半数妇女作过巴氏涂片,仅1/4人数是按期作的。若对所有妇女作巴氏涂片,宫颈癌是完全可以预防的,不仅能完全消灭,而且有癌前病变的,经保守治疗能治愈。流行病学:1973年Rotkin的流行病学综述中
Half a century ago, American women died of cervical cancer more than any other cancer, then a few years later, cervical cancer mortality decreased significantly, the current cervical cancer-causing deaths in women’s cancer patients accounted for the fifth. The incidence of invasive cancer decreased, while the new cervical epithelium detected significantly increased. The American Cancer Society estimated that in 1979, 16,000 women were diagnosed with invasive cancer, but more than 45,000 were confirmed as having cancer in situ. This change, at least in part, resulted in the discovery of intraepithelial neoplasms due to the widespread use of Pap smear in censuses. However, in the 1970s, only half of the women in the United States estimated that Pap smear was done, with only 1/4 being on schedule. If all women are Pap smear, cervical cancer is completely preventable, not only can be completely eliminated, and precancerous lesions, conservative treatment can be cured.
