Multimodality Treatments of HPV-related Lesions of the Female Genital Tract

May 6, 2025 updated by: Fondazione IRCCS Istituto Nazionale dei Tumori, Milano

Predictors of Recurrence After Treatment (Surgery Plus Vaccination) of HPV-related Disease of the Female Genital Tract

Cervical cancer is one of the most preventable types of cancer, as it develops over an extended period, and its causative agent is well-known. Persistent infection with human papillomavirus (HPV) is the primary factor causing cervical cancer. Generally, persistent HPV infection leads to cervical dysplasia (also known as cervical intraepithelial neoplasia), which can potentially progress to cancer. Although the majority of women with HPV infection will never develop lesions, a relatively high number of women remain at risk of developing cervical dysplasia. Women with cervical dysplasia who receive appropriate follow-up and treatment are at low risk of developing cervical cancer. However, recurrent cervical dysplasia is a well-known risk factor for cervical cancer. Furthermore, recurrent cervical dysplasia can contribute to morbidity, as additional surgical treatments are associated with fertility and obstetric complications in women who wish to preserve their childbearing potential. Against this background, identifying the best treatment modality for patients with cervical dysplasia is of paramount importance.

The management of residual or recurrent dysplasia after primary treatment is often challenging. Moreover, it is important to classify patients based on their risk of having persistent or recurrent dysplasia following initial treatment. Assessing these risk categories is useful in tailoring appropriate surveillance and determining the need for adjunctive treatments. Our research group has estimated the risk of developing persistent or recurrent dysplasia in several investigations, identifying positive surgical margins, surgical techniques, high-risk HPV infection at the time of diagnosis, and HPV persistence as key prognostic factors. Our findings align with a substantial body of literature investigating this issue. However, accurately estimating the risk of persistent or recurrent dysplasia for each individual patient remains challenging.

Similarly, few studies have evaluated the outcomes of patients affected by vaginal intraepithelial neoplasia, and results have been inconsistent. In fact, there is no consensus on the optimal treatment modality for these patients. Treatments have included topical applications of imiquimod or 5-fluorouracil (5-FU), as well as ablative and excisional procedures performed via conventional surgery, electrosurgery, and carbon dioxide laser. The risk of developing invasive vaginal cancer in these patients remains uncertain, with estimates ranging between 2% and 12% in different series. Recently, a multi-institutional Italian study reported that more than 10% of women initially diagnosed with high-grade vaginal intraepithelial neoplasia were found to have occult invasive vaginal cancer at the time of excisional procedures, highlighting the need for histological diagnosis before proceeding with ablative or medical treatments. Additionally, the widespread implementation of HPV vaccination is expected to reduce the risk of recurrence after treatment.

In this context, the investigators aim to evaluate the significance of post-treatment HPV vaccination and other prognostic factors in influencing the risk of persistent or recurrent lesions of the uterine cervix and vagina.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria
