Pathology – Cervical screening
primarily aims to detect cervical intraepithelial neoplasia (CIN). NHS cervical screening initiative All women aged 25 to 64 are eligible for cervical screening. Routine screening is conducted every three years from ages 25 to 49 and every five years from ages 50 to 64. The screening test involves a cervical sample ('smear') for liquid-based cytology. A specialized instrument is employed to collect cells from the cervix. The brush head is subsequently detached and placed into a small glass vial containing fixative or washed directly in the fixative. The specimen is subsequently dispatched to the local laboratory, where a processing apparatus generates a thin monolayer of cells on a glass plate for cytological analysis.
Cytopathology
The primary objective of cytological analysis of cervical specimens is the identification of dyskaryotic squamous epithelial cells. Dyskaryosis is classified as mild, moderate, or severe according on the degree of cellular abnormality. Women exhibiting a single test result indicative of moderate or severe dyskaryosis must be referred for colposcopy. Women exhibiting minor dyskaryosis in one test should ideally be referred to colposcopy; however, it is permissible to repeat the screening test initially. Women exhibiting mild dyskaryosis in two tests must be referred for colposcopy.
Colposcopy
Colposcopy is a comprehensive evaluation of the cervix with a binocular microscope known as a colposcope and a powerful light source. The application of acetic acid and iodine to the cervix facilitates the identification of potential regions of cervical intraepithelial neoplasia (CIN) for targeted biopsy.
Histopathology
Cervical biopsies are submitted for histological analysis to verify the existence of CIN and assign a grade from 1 to 3. CIN 1 exhibits squamous dysplasia characterized by abnormalities localized in the basal 1/3 of the epidermis. CIN 2 exhibits squamous dysplasia characterized by abnormalities localized in the basal two-thirds of the epithelium. CIN 3 exhibits squamous dysplasia characterized by abnormalities that penetrate the upper third of the epithelium.
Administration
CIN 2 and 3 are high-grade lesions that necessitate excision of the transformation zone. CIN 1 is a low-grade lesion that may be handled conservatively or excised, contingent upon the clinical circumstances.
