Cervical cancer: screening and therapeutic perspectives

Area of Science:

• Oncology
• Public Health
• Gynecology

Background:

• Cervical cancer disproportionately affects women in low- and medium-resource countries.
• Current screening methods like cytology have variable sensitivity, especially in developing nations.
• Human papillomavirus (HPV) testing is more sensitive but its long-term impact on protection is unclear.

Purpose of the Study:

• To review current strategies for cervical cancer prevention, screening, and treatment.
• To highlight the public health challenges and opportunities in cervical cancer control.
• To emphasize the role of primary care in managing cervical cancer.

Main Methods:

• Review of existing literature on cervical cancer screening and treatment.
• Analysis of the effectiveness of different diagnostic methods (cytology, HPV testing, visual inspection).
• Evaluation of treatment modalities for cervical intraepithelial neoplasia and cancer.

Main Results:

• Visual inspection with 4% acetic acid demonstrated a reduction in cervical cancer incidence and mortality in a recent trial.
• Cryotherapy and large loop excision are effective treatments for pre-cancerous lesions.
• Clinical stage is the primary prognostic factor influencing treatment decisions (surgery vs. radiotherapy).

Conclusions:

• Effective cervical cancer control requires robust public health infrastructure, including vaccination and screening programs.
• Visual inspection with acetic acid presents a viable option for screening in resource-limited settings.
• Primary care providers play a crucial role in the prevention, early detection, and management of cervical cancer.
