Experience with 40,000 Papanicolaou smears

Area of Science:

• Gynecology
• Oncology
• Cytopathology

Background:

• Cervical cancer screening relies on cytologic smears (Papanicolaou tests).
• Early detection of cervical neoplasia is crucial for effective treatment.
• Persistent atypical cytologic findings necessitate further investigation.

Purpose of the Study:

• To evaluate the diagnostic yield of Papanicolaou smears for cervical neoplasia.
• To assess the significance of atypical smears in identifying high-grade lesions.
• To determine the efficacy and safety of conization for diagnosing and managing cervical dysplasia and cancer.

Main Methods:

• Analysis of 40,000 consecutive cytologic smears and subsequent diagnostic procedures.
• Review of diagnostic outcomes, including carcinoma in situ, microinvasive/invasive carcinomas, and severe dysplasia.
• Evaluation of patients undergoing conization for persistent atypical smears.

Main Results:

• Significant neoplasia (carcinoma in situ, invasive cancer, severe dysplasia) detected at a rate of 1 per 400 Papanicolaou smears.
• 25 cases of carcinoma in situ and invasive cancers were diagnosed in patients with atypical smears.
• 78% of patients undergoing conization had significant cervical dysplasia or cancer.
• Conization showed negligible post-operative complications and no adverse effects on pregnancy.

Conclusions:

• Persistent atypical Papanicolaou smears require tissue examination for definitive diagnosis.
• Conization is a safe and effective procedure for diagnosing and managing cervical intraepithelial neoplasia and early-stage cervical cancer.
• Annual cytologic screening is recommended for sexually active women and virginal women over 20.
• A history of gonorrhea is a risk factor for cervical carcinoma.
