The purpose of this research is to study different strategies to identify women at highest risk for anal cancer. Primarily, investigators want to study a risk assessment called the Anal Cancer Risk Index; it gives women an overall number score based on risk factors that they may have for anal cancer, such as age, number of sexual partners, or smoking. Investigators seek to understand whether women with higher Anal Cancer Risk Index scores are more likely to have abnormal results on anal pap smears, HPV tests, or anal biopsies. The study team will collect swabs of the cervix and the anus to study different laboratory tests that could identify women at highest risk of cervical and anal cancer. These laboratory tests include an anal pap smear, tests for markers of disease and tests that detect the HPV types most likely to cause cancer. The study team would like to see which of these laboratory tests do the best job at predicting precancerous lesions in the anus and are better indicators of risk for cancer. After collecting these swabs, women will have a procedure called high resolution anoscopy where investigators look closely at the anus and biopsy any suspicious areas. Finally, the study team will look for HPV proteins and changes that HPV can make in cells to see if these tests predict anal lesions.

Next, the team will collect a swab of the cervix and swabs of the anus to study different laboratory tests that could identify women at highest risk of anal cancer: these tests include an anal pap smear and tests that detect HPV types most likely to cause cancer. Investigators would like to see which of these laboratory tests do the best job at predicting precancerous lesions in the anus. After collecting these swabs, women will have a procedure called high resolution anoscopy where investigators will look closely at the anus and biopsy any suspicious areas. Finally, the study team will look for HPV proteins and changes that HPV can make in cells to see if these tests predict anal lesions. The HPV protein is called E6 and E7 and the cell change test is called CADM1/MAL/miR-124-2. Investigators will measure E6/E7 and CADM1/MAL/miR-124-2 in cervical and anal samples to see if women positive for this marker are more likely to have abnormal results on anal pap smears or anal biopsies.

A species of gram-negative, facultatively anaerobic, rod-shaped bacteria found in humans and other animals including MAMMALS; BIRDS; REPTILES; and AMPHIBIANS. It has also been isolated from SOIL and WATER as well as from clinical specimens such as URINE; THROAT; SPUTUM; BLOOD; and wound swabs as an opportunistic pathogen.
Exocrine glands in animals which secrete scents which either repel or attract other animals, e.g. perianal glands of skunks, anal glands of weasels, musk glands of foxes, ventral glands of wood rats, and dorsal glands of peccaries.
A neuropsychological test designed to assess different memory functions. It may incorporate an optional cognitive exam (Brief Cognitive Status Exam) that helps to assess memory related cognitive function.
A network of nerve fibers originating in the upper four cervical spinal cord segments. The cervical plexus distributes cutaneous nerves to parts of the neck, shoulders, and back of the head, and motor fibers to muscles of the cervical spinal column, infrahyoid muscles, and the diaphragm.
