Difficulty: MediumGynecologic Oncology

A 46-year-old woman comes to the office to discuss the results of a recent routine Pap test, which was reported as atypical glandular cells (AGC). The patient has no current symptoms. Her menstrual cycles occur regularly every 28 days and last for 4 to 5 days. Her past medical history is significant for hypertension and class I obesity (BMI 32 kg/m2kg/m^2). She has had no prior abnormal Pap tests. Pelvic examination demonstrates a normal-appearing parous cervix with no visible lesions or gross blood. Bimanual examination reveals a mobile, normal-sized uterus with no adnexal masses. Which of the following is the most appropriate next step in the management of this patient?

  1. Colposcopy, endocervical sampling, and endometrial biopsyAnswer
  2. B
    Colposcopy and endocervical sampling only
  3. C
    Endometrial biopsy only
  4. D
    Reflex testing for high-risk human papillomavirus
  5. E
    Repeat cytology in 12 months

Answer

Colposcopy, endocervical sampling, and endometrial biopsy
The correct sequence of procedures evaluates both the endocervical and endometrial compartments. Atypical glandular cells (AGC) on cervical cytology carry a significant risk for underlying neoplasia, including cervical adenocarcinoma, endometrial adenocarcinoma, and high-grade squamous lesions. Because these lesions can originate from either the cervix or the endometrium, a thorough evaluation of both areas is required for specific populations. Current guidelines state that all women with AGC should undergo colposcopy with endocervical sampling (curettage). Additionally, because the risk of endometrial pathology increases with age, concurrent endometrial biopsy is mandated for all women ≥\ge 35 years of age. Women <35< 35 years of age also require endometrial biopsy if they have risk factors for endometrial cancer, such as obesity, chronic anovulation, or abnormal uterine bleeding. Given this patient is 46 years old, she must undergo endometrial sampling in addition to colposcopy and endocervical sampling.

Step-by-Step Solution

1
Analyze the patient's presentation and test results
The patient is a 46-year-old asymptomatic woman with a cervical cytology result showing Atypical Glandular Cells (AGC).
Identifying the specific cytologic abnormality is the first step in determining the diagnostic pathway.
2
Recall the potential origins and risks of AGC
AGC can originate from the endocervix or the endometrium, indicating a higher risk of cervical or endometrial adenocarcinoma compared to squamous cell abnormalities.
Understanding the pathophysiology explains why broad tissue sampling is required.
3
Apply the diagnostic algorithm based on the patient's age and risk factors
All women with AGC require colposcopy and endocervical sampling. Furthermore, women age 35 or older require concurrent endometrial biopsy.
Age is the primary determinant for adding endometrial sampling to the evaluation of AGC.
4
Determine the definitive next step for this specific patient
Since the patient is 46 years old, she unequivocally must undergo evaluation of both the cervix (colposcopy + endocervical sampling) and the endometrium (endometrial biopsy).
This comprehensively rules out malignancies from both potential origins of the atypical glandular cells.

Key Concept

Women aged 35 years or older with atypical glandular cells (AGC) on Pap testing require colposcopy, endocervical sampling, and endometrial biopsy to rule out both cervical and endometrial malignancies.
