This study will look at cervical tissue samples in women with abnormal cervical cells to see if the frequency of the HPV 16/18 subtypes has changed in female populations today, after the introduction of the HPV vaccine. It will compare women who have been exposed to the HPV vaccine with those who have not.
The development of cervical dysplasia (precursor to cervical cancer) and cervical cancer requires infection with one of several cancer causing subtypes of the human papilloma virus (HPV). There are over 100 subtypes of HPV, and most are not cancer causing. In the past, North American data has shown that 70% of early cervical cancers were associated with HPV subtypes 16 and/or 18. The first HPV vaccines to be approved protected against the common subtypes of HPV 16 and 18. The traditional HPV vaccination consists of 3-doses administered over a 6 month period.
Since the 8 years after the introduction of the vaccine, there have not been any studies analyzing HPV subtype changes. It is important to determine if the prevalence of the HPV subtypes associated with precancerous and/or early cervical cancer have changed, and what preventative outcomes have arisen from the HPV vaccination. This will have implications regarding the importance and anticipated effects of immunization with the nanovalent vaccine that includes other oncogenic subtypes.

A cytological test finding often from PAP SMEARS that shows abnormal lesions of SQUAMOUS EPITHELIAL CELLS of the CERVIX. It is a diagnostic criterion used in the Bethesda System for UTERINE CERVICAL NEOPLASMS and represents the PAP TEST result that is abnormal. Although squamous intraepithelial lesions test result does not mean UTERINE CERVICAL NEOPLASMS it requires follow-ups (e.g., HPV DNA TESTS; and COLPOSCOPY).
A malignant epithelial tumor of glandular tissue, especially the salivary glands, characterized by acini with mucus-producing cells and by the presence of malignant squamous elements. Most mucoepidermoid tumors are low-grade lesions readily cured by adequate excision. They may appear in any age group. They grow slowly. If high-grade, they behave aggressively, widely infiltrating the salivary gland and producing lymph node and distant metastases. (Dorland, 27th ed; from DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575)
Morphological abnormalities of the cervical EPITHELIUM, usually revealed in PAP SMEAR, which do not meet the criteria for squamous CERVICAL INTRAEPITHELIAL NEOPLASIA or SQUAMOUS CELL CARCINOMAS of the CERVIX . It may be a sign of infection with certain types of human papillomavirus (HPV).or sign of a benign (not cancer) growth, such as a cyst or polyp or, in menopausal women, of low hormone levels. More testing, such as HPV test, may be needed.
A tumor of both low- and high-grade malignancy. The low-grade grow slowly, appear in any age group, and are readily cured by excision. The high-grade behave aggressively, widely infiltrate the salivary gland and produce lymph node and distant metastases. Mucoepidermoid carcinomas account for about 21% of the malignant tumors of the parotid gland and 10% of the sublingual gland. They are the most common malignant tumor of the parotid. (From DeVita Jr et al., Cancer: Principles & Practice of Oncology, 3d ed, p575; Holland et al., Cancer Medicine, 3d ed, p1240)
White or pink lesions on the arms, hands, face, or scalp that arise from sun-induced DNA DAMAGE to KERATINOCYTES in exposed areas. They are considered precursor lesions to superficial SQUAMOUS CELL CARCINOMA.
