Interpreting Pap Results Edit

  • Atypical squamous Cells of Undertermined Significance (ASCUS)
    • < 30 years old: Repeat cytology in 6 months
      • Negative --> Repeat cytology in 6 months
        • Negative --> Routine screening
        • Positive >/+ ASCUS--> Colposcopy
      • Positive>/= ASCUS --> Colposcopy
    • >30 years old:
      • HPV testing available
        • Negative --> Repeat cytology in 12 months
          • Negative --> routine screening
          • Positive --> colposcopy
        • Positive --> Colposcopy
      • HPV testing not available
        • As per age < 30 guidelines
  • Atypical Squamous Cells Cannot Exclude HSIL (ASC-H) --> colposcopy
  • Atypical glandular cells/atypical endocervical cells/ atypical endometrial cells --> colposcopy and/or endometrial sampling
  • Low-Grade Squamous Intraepithelial Lesion (LSIL)
    • Repeat cytology in 6 months
      • Negative - repeat cytology in 6 months
        • Negative - routine screening
        • Positive >/=ASCUS - colposcopy
      • Positive - colposcopy
    • OR Colposcopy (can be used after first LSIL)
  • High- Grade Squamous Intraepithelial Lesion (HSIL) --> colposcopy
  • Squamous carcinoma/adenocarcinoma/malignant neoplasm -->colposcopy
  • Unsatisfactory for Evaluation --> repeat cytology in 3 months
  • Satisfactory for evaluation, No transformation Zone present --> routine screening in 3 years
  • Benign endometrial cells:
    • Pre-menopausal (asymptomatic): routine screening
    • Post-menopausal: endometrial sampling
