## Introduction

Cervical cancer is a significant public health concern, with human papillomavirus (HPV) infection as the primary etiological factor. Early detection through screening and appropriate management are crucial in reducing the burden of this preventable disease. This clinical reference document provides a comprehensive overview of the screening, diagnosis, and management of cervical cancer associated with HPV infection.

## Epidemiology and Risk Factors

Cervical cancer is the fourth most common cancer in women worldwide, with an estimated 569,000 new cases and 311,000 deaths in 2018 [1]. The primary risk factor for cervical cancer is persistent infection with high-risk HPV types, particularly HPV-16 and HPV-18, which account for approximately 70% of cervical cancer cases [2]. Other risk factors include smoking, immunosuppression, and a history of sexually transmitted infections.

## Screening Recommendations

The American Cancer Society (ACS), the U.S. Preventive Services Task Force (USPSTF), and the American College of Obstetricians and Gynecologists (ACOG) recommend the following cervical cancer screening guidelines [3,4,5]:

- Women aged 21-29 years: Cytology (Pap test) every 3 years
- Women aged 30-65 years: Cytology every 3 years or co-testing with cytology and HPV testing every 5 years
- Women aged 65 and older: Screening can be discontinued if previous screening was adequate, and the patient is not at high risk for cervical cancer.

Individuals with a history of cervical cancer, a compromised immune system, or in-utero exposure to diethylstilbestrol (DES) may require more frequent screening.

## Diagnostic Evaluation

The diagnostic workup for suspected cervical cancer includes the following:

1. Pap test: This cytological examination of cervical cells can detect precancerous changes (cervical intraepithelial neoplasia, CIN) and early-stage cervical cancer.

2. HPV testing: High-risk HPV DNA testing can be used in conjunction with Pap tests or as a primary screening tool to detect the presence of oncogenic HPV types.

3. Colposcopy and biopsy: If the Pap test or HPV test results are abnormal, a colposcopic examination and biopsy of the cervix are performed to confirm the diagnosis and determine the extent of disease.

4. Imaging: In cases of suspected advanced disease, imaging modalities such as pelvic magnetic resonance imaging (MRI) or positron emission tomography (PET)/computed tomography (CT) may be utilized to assess the extent of the tumor and identify any metastatic spread.

## Treatment and Management

The management of cervical cancer is primarily based on the stage of the disease and the patient's overall health status. The following treatment approaches are commonly used:

1. Early-stage cervical cancer (stages I-IIA):
   - Treatment options include surgery (e.g., conization, hysterectomy) or definitive chemoradiation therapy.
   - For early-stage, small-volume disease, the FIGO (International Federation of Gynecology and Obstetrics) staging system is used to guide treatment [6].

2. Locally advanced cervical cancer (stages IIB-IVA):
   - Definitive chemoradiation therapy is the standard of care, consisting of external beam radiation therapy (EBRT) and concurrent cisplatin-based chemotherapy.
   - Brachytherapy (internal radiation therapy) is often used in conjunction with EBRT to deliver a high dose of radiation to the tumor while sparing surrounding healthy tissues.

3. Metastatic or recurrent cervical cancer (stage IVB):
   - Treatment options may include systemic chemotherapy, targeted therapy (e.g., pembrolizumab), or palliative care, depending on the patient's overall health and disease status.
   - The choice of systemic therapy is guided by the patient's performance status, prior treatment history, and tumor characteristics.

Monitoring and follow-up for cervical cancer patients include regular physical examinations, Pap tests, and imaging studies (e.g., CT, PET/CT) to detect any recurrence or progression of the disease.

## Preventive Strategies

In addition to screening and early detection, preventive strategies for cervical cancer include:

1. HPV vaccination:
   - The HPV vaccines Gardasil and Cervarix are recommended for all individuals aged 11-26 years, regardless of prior HPV exposure [7].
   - The vaccines provide protection against the most common high-risk HPV types (16 and 18) that cause approximately 70% of cervical cancers.

2. Smoking cessation:
   - Smoking is an independent risk factor for cervical cancer and can also reduce the efficacy of cervical cancer screening and treatment.
   - Clinicians should strongly encourage and support smoking cessation efforts in all patients, particularly those at high risk for cervical cancer.

3. Immunocompetence optimization:
   - Patients with compromised immune systems, such as those with HIV/AIDS or undergoing immunosuppressive therapy, should be monitored closely and receive more frequent cervical cancer screening.

By implementing these comprehensive preventive strategies, along with effective screening and early treatment, the burden of cervical cancer can be significantly reduced.

## Conclusion

Cervical cancer associated with HPV infection remains a significant public health concern, but effective screening, early detection, and appropriate management can significantly improve patient outcomes. Clinicians should be familiar with the current screening recommendations, diagnostic evaluation, and treatment approaches to provide comprehensive care for individuals at risk of or diagnosed with cervical cancer.
