A clinical study to determine the adequacy and efficacy of the InPath e2TM Collector compared to the FDA-approved spatula/cytobrush when used as the cell collection device in screening for cervical cancer.

The InPath e2TM Collector name has been changed to the CytoCore SoftPAP(R) Collector

Condition Intervention
Colposcopy Biopsy Device: e2 Cell Collector [SoftPAP(R)] Device: Spatula/Brush

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Clinical Study Validating the Adequacy, Efficacy, and Safety of the e2TM Cervical Cell Collector Compared to Standard Spatula/CytoBrush Technique In Patients With Recent History of Abnormal Pap Test Returning for Colposcopy/Biopsy.

Study Completion Date: May 2008
Primary Completion Date: May 2008 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Arm 1 - Experimental
e2 Cell Collector [SoftPAP(R)]
Device: e2 Cell Collector [SoftPAP(R)]
Cervical cells collected using the e2 Cell Collector [SoftPAP(R)]
Arm 2 - Control
Device: Spatula/Brush
Cervical cells collected using a combination of a cervical spatula and an endocervical brush

Detailed Description:
The e2TM (SoftPAP) Collector collects only cells that have been exfoliated from the cervix whereas spatulas, brushes and broom-style collection devices collect cells by scraping or abrading the cervix. THis trial is to determine whether the purely exfoliated sample collected using the e2TM Collector is equivalent to samples obtained by scraping or abrading the cervix for purposes of cervical cancer screening and HPV detection.
