Screening Women With Prior HPV for Anal Neoplasia (SWAN)

The Effectiveness of Screening Women With Lower Genital Tract Neoplasia or Cancers for Anal Cancer Precursors

The goal of this single arm trial is to prospectively evaluate screening methods for anal cancer precursors in HIV uninfected women with a history of lower genital tract neoplasias and cancers.

Study Overview

• Status: Recruiting
• Conditions: HPV-related Lower Genital Tract Neoplasias; HPV-related Anal Neoplasias; Early Stage Lower Genital Tract Cancers
• Intervention / Treatment: Diagnostic test: Diagnostic tests for anal cancer screening

Detailed Description

This single arm trial will enroll 300 HIV uninfected women with a history of genital neoplasia (ie., cervical intraepithelial neoplasia grade 2-3, vaginal intraepithelial neoplasia grade 2-3 or vulvar intraepithelial neoplasia grade 2-3) or early stage cervical or vulvar cancer to evaluate the test characteristics of anal cancer screening tests (cytology, HPV testing and high resolution anoscopy) and determine the prevalence and incidence of anal high-grade squamous intraepithelial lesions in this population. Participants will undergo evaluation at baseline and then at 12 and 24 months. The investigators will also measure the acceptability of anal cancer screening in this previously unstudied group. The trial is expected to run from 2021-2027.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Women With Prior HPV for Anal Neoplasia; Standard of care anal cancer screening with anal cytology, HPV testing and high resolution anoscopy.	Diagnostic test: Diagnostic tests for anal cancer screening; The initial screening interventions will include the collection of (1) anal cytology; (2) self-collected HPV testing specimens (by subjects); (3) a clinician collected HPV specimen. A digital rectal exam will also be done on all patients.

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Concordance of self- and clinician-collected PCR testing	Proportionate concordance of high-risk HPV testing	baseline
Prevalence of hrHPV types at baseline	Proportion of subjects with high-risk HPV and subtype proportions	Baseline
hrHPV with Cobas PCR testing (self-collected)	Presence of high-risk HPV subtype	Baseline
hrHPV with Cobas PCR testing (self-collected)	Presence of high-risk HPV subtype	12 months
hrHPV with Cobas PCR testing (self-collected)	Presence of high-risk HPV subtype	24 months
hrHPV with Cobas PCR testing (clinician-collected)	Presence of high-risk HPV subtype	Baseline
hrHPV with Cobas PCR testing (clinician-collected)	Presence of high-risk HPV subtype	12 months
hrHPV with Cobas PCR testing (clinician-collected)	Presence of high-risk HPV subtype	24 months
Prevalence of aHSIL at baseline	Proportion of subjects with aHSIL	Baseline
Incidence of aHSIL at follow-up	Proportion of subjects with new aHSIL during follow-up period	24 months
Screening Experience Survey	Survey measures anal cancer screening test acceptability. Each item is scored 0-3, with higher score indicting more acceptability. 0-3. There is no total scale. Each question is scored separately and the overall results are used qualitatively.	Baseline
