CIN 1–2–3 (Cervical Lesions)

What Are CIN Lesions?

Cervical Intraepithelial Neoplasia (CIN) refers to abnormal cellular changes on the cervix caused primarily by persistent infection with high-risk Human Papillomavirus (HPV).
These changes are not cancer, but if left untreated, some may progress to cervical cancer over several years.

CIN is classified into three grades based on how deep the abnormal cells extend into the cervical lining:

• CIN 1: Mild dysplasia (changes in the lower third of the epithelium)
• CIN 2: Moderate dysplasia (up to two-thirds of the epithelium)
• CIN 3: Severe dysplasia or carcinoma in situ (full-thickness changes, but no invasion)

What Causes CIN?

The main cause of CIN is persistent infection with high-risk HPV types, especially HPV 16 and HPV 18.
Additional contributing factors include:

• Early sexual activity and multiple partners
• Smoking
• Weak immune system
• Long-term use of hormonal contraceptives
• History of other sexually transmitted infections (STIs)

Symptoms and Detection

CIN rarely causes noticeable symptoms. Most cases are detected through:

• Abnormal Pap smear results
• Positive HPV DNA test
• Colposcopy and cervical biopsy

Occasionally, some women may experience:

• Abnormal vaginal bleeding (after intercourse or between periods)
• Unusual discharge
• Pelvic discomfort

However, these symptoms are not specific and may also occur in benign conditions.

Diagnosis

Diagnosis typically involves:

1. Pap smear: Detects abnormal cervical cells.
2. HPV DNA test: Identifies high-risk viral types responsible for changes.
3. Colposcopy: Magnified examination of the cervix.
4. Biopsy: Confirms the grade of CIN and rules out invasion.

All tests are performed at Saga Clinic using advanced imaging and molecular diagnostic technologies, ensuring accurate and timely results.

Understanding the CIN Grades

CIN 1 – Mild Dysplasia

• Low-grade lesion (LSIL)
• Often regresses spontaneously within 12–24 months
• Usually managed with observation and HPV follow-up
• Repeat Pap and HPV testing every 6–12 months

CIN 2 – Moderate Dysplasia

• Intermediate-grade lesion (HSIL)
• May regress, persist, or progress if untreated
• Requires colposcopic evaluation and possible biopsy or excisional procedure (LEEP)
• Follow-up testing after treatment to confirm clearance

CIN 3 – Severe Dysplasia / Carcinoma In Situ

• High-grade lesion (HSIL)
• Pre-cancerous stage; requires prompt treatment
• Treated with LEEP, laser ablation, or cone biopsy
• Regular monitoring post-treatment to prevent recurrence

Treatment Options at Saga Clinic

The choice of treatment depends on the CIN grade, age, fertility plans, and HPV status.
At Saga Clinic in Tirana, under Dr. Eser Agar, management follows international (ASCCP, ESGO, WHO) guidelines and includes:

• Observation and repeat testing for CIN 1
• LEEP (Loop Electrosurgical Excision Procedure) for CIN 2–3
• Laser ablation or cold knife conization in selected cases
• HPV vaccination for prevention of reinfection

Every patient receives a personalized follow-up plan, combining Pap, HPV, and colposcopy assessments for long-term safety.

Prognosis and Follow-up

• CIN 1: 60–90% regress naturally
• CIN 2: 40–50% regress; 20% may progress
• CIN 3: 10–20% risk of progression to invasive cancer if untreated

After treatment, follow-up is essential every 6–12 months with Pap and HPV testing to ensure clearance and prevent recurrence.
