Studying Biomarkers in Diagnosing Cervical Lesions in Patients With Abnormal Cervical Cells

• CA-IX , high-risk HPV, p16, Ki-67, and MCM2 expression in patients in North America [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  A logistic regression and ROC-type analysis will be performed.
  
  
• CA-IX , high-risk HPV, p16, Ki-67, and MCM2 expression in patients in Japan [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  A logistic regression and ROC-type analysis will be performed.
  
  

• Effect of patient age and country (North America or Japan) on the accuracy of diagnosis based on CA-IX, HPV, p16, Ki-67, and/or MCM2 expression [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  Logistic regression analyses will be performed.
  
  
• Inter- and intra-reviewer reproducibility of scoring CA-IX, p16, Ki-67 and MCM2 biomarkers [ Time Frame: Baseline ] [ Designated as safety issue: No ]
  Logistic regression analyses will be performed.

PRIMARY OBJECTIVES:

I. To examine the expression of CA-IX, high-risk human papilloma virus (HPV), p16, Ki-67, and MCM2 in liquid-based cytology (LBC) specimens to determine which subset of markers will provide the optimal diagnosis of significant cervical lesions in patients in North America with atypical glandular cells (AGC).

II. To examine the expression of CA-IX, high-risk HPV, p16, Ki-67, and MCM2 in LBC specimens to determine which subset of markers will provide the optimal diagnosis of significant cervical lesions in patients in Japan with AGC.

SECONDARY OBJECTIVES:

I. To determine whether the accuracy of diagnosis based on CA-IX, HPV, p16, Ki-67, and/or MCM2 expression varies with patient age at study enrollment and country of enrollment (North American or Japan).

II. To assess the inter- and intra-reviewer reproducibility of scoring CA-IX, p16, Ki-67, and MCM2.

OUTLINE: This is a multicenter study.

Patients undergo a cone biopsy of the cervix by loop electrosurgical excision procedure (LEEP)* with or without endocervical curettage, an excisional cone biopsy* of the cervix with or without endocervical curettage, or a hysterectomy within 6 months after the initial cytologic diagnosis of atypical glandular cells (AGC). A complete histological examination of the cervix, including the transformation zone is performed.

NOTE: *Patients 35 years of age with negative cervical LEEP or excisional cone biopsy must undergo endometrial biopsy or curettage.

Liquid-based cytology specimens are collected within 1 week of study entry (prior to colposcopy examination and/or any surgical procedure). Specimens are analyzed for CA-IX, p16, Ki-67, and MCM2 expression by immunohistochemistry assays and for the presence of high-risk human papilloma virus (HPV) by Digene Hybrid Capture II HPV testing and Roche Linear Array HPV genotyping.
