Zorluk: OrtaPreventive Care and Screening

A 48-year-old woman is evaluated during a routine health maintenance visit. She has no current medical complaints and feels well. Her surgical history is significant for a total abdominal hysterectomy with bilateral salpingectomy performed three years ago for symptomatic uterine fibroids. Her ovaries were preserved. Review of her medical records shows that her most recent cervical cancer screening, performed four years ago prior to her surgery, revealed atypical squamous cells of undetermined significance (ASC-US) with a negative high-risk human papillomavirus (hrHPV) test. She has no prior history of cervical intraepithelial neoplasia (CIN) 2, CIN 3, or cervical cancer, and she has not undergone any screening tests since her operation. She is in a monogamous relationship and does not smoke. Vital signs and physical examination are unremarkable. Which of the following is the most appropriate next step in screening for this patient?

  1. Discontinue cervical cancer screeningCevap
  2. B
    Perform vaginal cuff cytology alone
  3. C
    Perform vaginal cuff cytology and hrHPV co-testing
  4. D
    Perform a screening transvaginal ultrasound
  5. E
    Schedule a screening colposcopy of the vaginal vault

Cevap

Discontinue cervical cancer screening
The correct answer is to discontinue cervical cancer screening. According to USPSTF guidelines, women who have undergone a total hysterectomy (which involves the removal of both the uterus and the cervix) for benign indications should not undergo further screening. The critical caveat is that patients with a history of a high-grade precancerous cervical lesion (CIN 2 or CIN 3) or cervical cancer must continue screening of the vaginal vault for 25 years after treatment. Although this patient had a prior abnormal result (ASC-US), her concurrent negative hrHPV test indicated a very low risk for high-grade dysplasia. Because ASC-US does not qualify as a high-grade precancerous lesion, she meets the criteria for permanent discontinuation of screening.

Adım Adım Çözüm

1
Identify the patient's surgical history and prior screening results.
The patient had a total hysterectomy (cervix removed) for benign fibroids. Her last screening showed ASC-US with negative hrHPV.
Surgical history and previous dysplasia history determine the necessity of ongoing cervical/vaginal vault screening.
2
Evaluate the clinical significance of the prior ASC-US result.
ASC-US with a negative hrHPV test is considered a normal/low-risk finding. It does not meet the criteria for a high-grade precancerous lesion (CIN 2 or CIN 3).
Ongoing screening is only indicated if the patient had a documented history of CIN 2, CIN 3, or cervical cancer prior to hysterectomy.
3
Apply the appropriate USPSTF preventive screening guideline.
Since the patient lacks a cervix and has no history of high-grade dysplasia or cancer, cervical/vaginal screening should be discontinued (Grade D recommendation).
To prevent harm from false positives and unnecessary procedures, evidence-based guidelines recommend halting screening in this population.

Cervical cancer screening should be discontinued in women who have undergone a total hysterectomy for benign disease and have no history of high-grade precancerous lesions (CIN 2 or 3) or cervical cancer.
