Immediate Treatment vs Colposcopic Follow-up for Biopsy-Proven CIN 1

2014-07-23 21:48:47 | BioPortfolio

Summary

This study looks at immediate treatment of a cervix with CIN 1 versus regular six-month follow-up with colposcopy and treatment if CIN 1 progresses.

Description

In women who present with biopsy-proven CIN 1, to compare the management approach of regular colposcopic follow-up and only treating progressive disease using the LEEP, with an approach of immediate treatment using LEEP. The primary outcome is progression to more advanced disease (i.e., CIN 2, CIN 3 or cancer).

Medical and Biotech [MESH] Definitions

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 malignancy arising in uterine cervical epithelium and confined thereto, representing a continuum of histological changes ranging from well-differentiated CIN 1 (formerly, mild dysplasia) to severe dysplasia/carcinoma in situ, CIN 3. The lesion arises at the squamocolumnar cell junction at the transformation zone of the endocervical canal, with a variable tendency to develop invasive epidermoid carcinoma, a tendency that is enhanced by concomitant human papillomaviral infection. (Segen, Dictionary of Modern Medicine, 1992)

A premalignant change arising in the prostatic epithelium, regarded as the most important and most likely precursor of prostatic adenocarcinoma. The neoplasia takes the form of an intra-acinar or ductal proliferation of secretory cells with unequivocal nuclear anaplasia, which corresponds to nuclear grade 2 and 3 invasive prostate cancer.

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 surgical procedure involving the excision of the COLON and RECTUM and the formation of an ILEOANAL RESERVOIR (pouch). In patients with intestinal diseases, such as ulcerative colitis, this procedure avoids the need for an OSTOMY by allowing for transanal defecation.
