Definition of Cervical Carcinoma in SituPreinvasive cervical carcinoma is referred to as carcinoma in situ, or cervical intraepithelial neoplasia III.
Description of Cervical Carcinoma in SituThe squamocolumnar junction of the cervix is an area of active squamous cell proliferation. At puberty, due to hormonal changes and possibly due to changes in vaginal acidity, the squamous margin begins to encroach on the single layer of mucus-secreting cells, creating an area of metaplasia (cellular changes) known as the "transformation zone." Over time, varying degrees of atypical cellular changes may occur consistent with squamous cell dysplasia or cancer. Currently, the malignant potential of a specific lesion cannot be predicted, so all types of dysplasia must be observed and treated if they persist or become more severe. Text Continues Below
Causes and Risk Factors of Cervical Carcinoma in SituRisk factors for cervical cancer include: - Frst sexual experience at an early age
- Having multiple sex partners, or having male sex partners who themselves have had multiple partners
- A current or prior human Papillomavirus (HPV) infection, condylomata or both
- HIV infection
- A history of other sexually transmitted diseases (STDs), including herpes simplex virus
- Immunosuppression
- Having had abnormal Pap smears in the past
- Cigarette smoking
- A history of cervical dysplasia or cervical, endometrial, vaginal or vulvar cancer
Symptoms of Cervical Carcinoma in SituThere are no specific symptoms or signs of cervical intraepithelial neoplasia.
Diagnosis of Cervical Carcinoma in SituDiagnosis is made by Pap smear during pelvic examination, colposcopy (viewing the cervix with 10-20x magnification), and punch biopsy (obtaining small amounts of tissue for analysis under the microscope) and endocervical curettage (gentle scraping of the cervical opening).
Treatment of Cervical Carcinoma in SituIn women who have completed childbearing, total hysterectomy (removal of the entire uterus) is the treatment of choice. In other women, acceptable options include cervical conization (surgical removal of the entire "transformation zone" and endocervical canal), or in experienced hands, destruction of the lesion with cryotherapy or laser treatment. Close follow-up with Pap smears every four months for one year and every six months for one year are necessary after cryotherapy or laser treatment.
Prevention of Cervical Carcinoma in SituPreventive measures include:1. Regular Pap smears 2. Limiting the number of sexual partners 3. Using a latex condom for intercourse 4. Stopping smoking
