Human papillomavirus (HPV) has been identified as a necessary factor in the development of pre-invasive and invasive cancers of the lower genital tract, of which cervical cancer is the most prevalent. A molecular understanding of malignant transformation and epidemiologic information has led to the development of many strategies for detection and early intervention. Newer tests for oncogenic subtypes of HPV have made it possible to predict the risk of future development of cervical cancer. This review summarizes the current understanding of HPV related disease and examines the role of HPV testing as a screening tool for cervical cancer. It summarizes the data from prospective and randomized controlled trials on HPV screening from Europe and North America and includes smaller studies from low and middle income countries where cervical cancer is the most common cancer in women.

Cervical cancer is both preventable and curable, yet it remains one of the leading causes of mortality in women worldwide. Approximately 88% of cervical cancer cases are diagnosed in low-resource countries, yet very few resources are allocated to prevention and treatment programs. In fact, it is estimated that only 5% of women in low-resources countries are screened appropriately for cervical cancer. Cytology-based programs are not feasible because of lack of healthcare infrastructure and cost, thus alternative methods of cancer screening, such as visual inspection with acetic acid and HPV-DNA testing, have been intensively studied and are reviewed in this article.
Objective. The objective of this study was to review the role of bilateral salpingo‐oophorectomy in BRCA mutation (mBRCA) carriers and alternative interventions in risk reduction of ovarian cancer (OC). Materials and Methods. A systematic review using PubMed, MEDLINE, EMBASE, and the Cochrane library was conducted to identify studies of different strategies to prevent OC in mBRCA carriers, including bilateral salpingo‐oophorectomy, prophylactic salpingectomy with delayed oophorectomy, intensive surveillance, and chemoprevention. Results. Risk‐reducing bilateral salpingo‐oophorectomy is an effective intervention, but its associated morbidity is substantial and seems to curtail uptake rates among the target population. Although there is much interest and a strong theoretical basis for salpingectomy with delayed oophorectomy, data on its clinical application are scarce with regard to screening, the use of an algorithmic protocol has recently shown favorable albeit indefinite results in average‐risk postmenopausal women. Its incorporation into studies focused on high‐risk women might help solidify a future role for screening as a bridge to surgery. The use of oral contraceptives for chemoprevention is well supported by epidemiologic studies. However, there is a lack of evidence for advocating any of the other agents proposed for this purpose, including nonsteroidal anti‐inflammatory drugs, vitamin D, and retinoids. Conclusion. Further studies are needed before salpingectomy with delayed oophorectomy or intensive surveillance can be offered as acceptable, less morbid alternatives to upfront oophorectomy for mBRCA carriers. Implications for Practice. Risk‐reducing bilateral salpingo‐oophorectomy is currently the most effective method for reducing the risk of ovarian cancer in BRCA mutation (mBRCA) carriers. Unfortunately, it is associated with significant short‐ and long‐term morbidity, stemming from reduced circulating estrogen. In recent years, much research has been devoted to evaluating less morbid alternatives, especially multimodal cancer screening and prophylactic salpingectomy with delayed oophorectomy. This review describes the present state of the art, with the aim of informing the counseling provided to mBRCA carriers on this complicated issue and encouraging additional research to facilitate the incorporation of such alternatives into routine practice.
