About this study

Official title: Predictive Value of p16 and Ki-67 Immunohistochemical Staining and NK Cells in Expectant Management of Cervical Intraepithelial Neoplasia Grade 2

The objective of this study is to evaluate the outcome of cervical intraepithelial neoplasia grade 2 (CIN-II) patients followed up without treatment for 24 months according to p16 and ki-67 immunohistochemical staining and to the expression of NK cell receptors.

Read the detailed description

Cervical cancer and its precursor lesions, cervical intraepithelial neoplasia (CIN), represents a significant public health problem,induced by persistent infection of human papillomavirus (HPV). It is known that a significant percentage of CIN regresses spontaneously and only a minority of these lesions progress to cervical cancer. CIN-II is an intermediate state that can regress to CIN-I or less, or progress to CIN-III spontaneously. The rate of spontaneous regression and progression in follow-up studies are around 40-60% and 10-20%, respectively. Overestimating CIN-II lesions may cause overtreatment by excisional treatment and increase the risk of subsequent obstetric complications.

Patients newly diagnosed with CIN-II colposcopy-directed biopsy who agreed to follow up at four months intervals for at least 12 months with cervical cytology and colposcopy, were prospectively recruited. p16, ki-67 and NK receptors expression were analyzed in all CIN-II biopsies. Total regression, partial regression, persistence and progression rates of CIN-II were defined as a final outcome.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Status of cervix pathology using cervical smear test (CIN grade)

    Cervical cytology test and colposcopy every 4 months starting with diagnose CIN-II or CIN-III means presence of lesion, CIN-I is regression of the lesion, and Negative is abscence of lesion.

    Measured: 2 years

Questions about this trial

What is this clinical trial studying?

An observational study of Cervical Cancer, run by Parc de Salut Mar.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 8 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 20 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Status of cervix pathology using cervical smear test (CIN grade) (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02522585, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 20 Apr 2016.
