- W2415915087 abstract "Papanicolaou testing has been held as the gold standard of screening programs as it is capable of detecting early, curable disease. This is true, as the microscopic evaluation of exfoliated cells or those obtained by a spatula does lead to lives saved; mortality rates from cervical cancer have plummeted where it has been introduced—for example, by 70% in the United States over the past 60 years.However, the age at onset of screening, its frequency, the age at stopping screening, and cotesting with human papillomavirus (HPV) DNA have all come under review as the pathology of cervical cancer has become better understood. The role of HPV as a causative agent when recurrently present has stimulated changes in approaches from primary prevention through vaccination, to various recommendations concerning Papanicolaou and HPV DNA testing. The screening programs of 10 years ago are no longer evidence based and will undoubtedly change as more data about HPV-vaccinated women become available. So what are the current recommendations for screening? The answer is that they vary from country to country, even where resources are plentiful.In the United States, the guidelines have been radically revised in the past 2 years. Despite three authoritative bodies offering different recommendations there is reasonable consensus as follows:Age to start testing: Age 21 years (cf, age 25 years in many European countries) and not at the onset of sexual activity.Frequency of testing: Every 3 years (previously annually).Cotesting with HPV DNA: Cotesting is not uniformly recommended prior to age 30 years and it is not indicated unless specific circumstances are present, such as recurrent cytological abnormalities (reflex testing). Even over age 30 years, routine HPV DNA testing is of dubious value.Age to stop testing: Generally age 65 years, provided the woman has had consistently negative screening.Posthysterectomy: Unnecessary if the histology did not reveal dysplasia or cancer.There are at present no separate recommendations for HPV-vaccinated women.It is clear that routine screening of low-risk women is becoming less intensive as evidence accumulates on the natural history of HPV infections. Testing will become individualized for the vaccinated patient and the highrisk, immunosuppressed patient. The call for clinical judgment and personalized care is clear.1The situation is very different in countries with low resources. Because of limited access to screening of any type, it is important that the test is accurate, cost effective, and detects cervical intraepithelial neoplasia of high grades and cancer. Under these circumstances, self-collection of vaginal samples for HPV DNA testing is a realistic option, as proven by a large trial in Mexico comparing the technique with conventional cytology.2 Although the present cost of HPV testing is relatively high, the high sensitivity of the screening carries advantages where the women may only present a few times for screening in their lives.In the trial, women found self-sampling more acceptable than clinic visits, and once cost and positive-result triaging problems can be resolved, HPV DNA testing could be the screening method of choice in developing countries.In the American literature, there are appeals for a less blanket approach to screening and routine investigations and one wonders when the US annual pelvic examination will come under rigorous investigation." @default.
