Zorluk: KolayGynecologic Oncology

A 35-year-old premenopausal woman, gravida 2, para 2, presents to her gynecologist for routine health maintenance. She has no active complaints, and her past medical history is unremarkable. Speculum examination reveals a normal-appearing cervix with no gross lesions. Arrange the following events in the standard sequential clinical pathway, from her initial screening abnormality to the definitive management of high-grade cervical dysplasia.

  1. 1Routine cervical cytology reporting Atypical Squamous Cells of Undetermined Significance (ASC-US)
  2. 2Reflex testing of the specimen returning positive for high-risk human papillomavirus (hrHPV)
  3. 3Colposcopic examination with directed biopsies confirming Cervical Intraepithelial Neoplasia grade 3 (CIN 3)
  4. 4Loop electrosurgical excision procedure (LEEP) to excise the cervical transformation zone

Cevap

The correct sequence begins with an ASC-US cytology result, followed by positive reflex hrHPV testing, leading to a colposcopy with biopsy confirming CIN 3, and concluding with a LEEP for definitive treatment.
The algorithm for cervical cancer screening and prevention follows a stepwise approach from screening to definitive diagnosis and subsequent treatment. In a 35-year-old woman, an initial screening cytology showing Atypical Squamous Cells of Undetermined Significance (ASC-US) requires triage to determine the risk of underlying high-grade dysplasia. The preferred triage method is reflex testing for high-risk HPV. If the hrHPV test is positive, the patient's risk for significant dysplasia is elevated, mandating colposcopy for direct visualization and directed biopsies. Once a tissue diagnosis of a high-grade lesion like CIN 3 is confirmed via biopsy, definitive excisional treatment, such as a Loop Electrosurgical Excision Procedure (LEEP), is required to remove the transformation zone and prevent progression to invasive cervical cancer.

Adım Adım Çözüm

1
Identify the initial screening abnormality.
The clinical pathway begins with an indeterminate cytology result of ASC-US.
ASC-US requires triage to determine the patient's risk of underlying high-grade dysplasia.
2
Determine the appropriate triage step for ASC-US.
Reflex testing for high-risk HPV.
Current guidelines recommend hrHPV testing to stratify risk; a positive result indicates a higher risk for significant dysplasia and the need for further diagnostic workup.
3
Identify the next diagnostic step following a positive triage result.
Colposcopy with directed biopsies.
Direct visualization and targeted tissue sampling are required to definitively diagnose the presence and severity of cervical dysplasia.
4
Determine the definitive management for the confirmed high-grade lesion.
Excisional procedure such as LEEP.
CIN 3 is a high-grade precancerous lesion with significant malignant potential that must be removed to prevent progression to invasive cervical cancer.
