From the Guidelines
Abnormal Pap smear results require immediate attention and follow-up, with the specific next steps depending on the stage and type of abnormality, as outlined in the most recent guidelines 1. The main categories of abnormal Pap smear results include: ASCUS (Atypical Squamous Cells of Undetermined Significance), LSIL (Low-grade Squamous Intraepithelial Lesion), HSIL (High-grade Squamous Intraepithelial Lesion), ASC-H (Atypical Squamous Cells, cannot exclude HSIL), and AGC (Atypical Glandular Cells).
- ASCUS typically requires HPV testing or repeat Pap in 12 months, as the risk of HSIL and cancer is relatively low (6.9%) 1.
- LSIL is usually managed with colposcopy or repeat testing depending on age and HPV status, with a risk of HSIL and cancer of 16% 1.
- HSIL requires prompt colposcopy with biopsy, as the risk of HSIL and cancer is high (69%) 1.
- ASC-H also requires colposcopy, with a risk of HSIL and cancer of 45% 1.
- AGC necessitates colposcopy with endocervical sampling, with a risk of HSIL and cancer of 13% 1. For colposcopy, a doctor examines the cervix under magnification and may take biopsies of suspicious areas. If precancerous changes are confirmed, treatment options include LEEP (Loop Electrosurgical Excision Procedure), cryotherapy, laser therapy, or conization to remove abnormal tissue, with the goal of preventing progression to cervical cancer and reducing morbidity and mortality 1. Regular follow-up is essential after any abnormal result or treatment, usually with more frequent Pap tests for several years, to ensure that any potential recurrence is detected and treated promptly, thereby improving quality of life and reducing the risk of complications 1. HPV vaccination is recommended for prevention if you haven't been vaccinated already, as most cervical abnormalities are caused by HPV infection, and vaccination can help reduce the risk of future abnormalities and improve overall health outcomes 1.

Abnormal PAP Smear Results Stages and Next Steps
Abnormal PAP smear results can be classified into different stages, each with its own set of next steps. The following are the stages and next steps:
- ASC-US (Atypical Squamous Cells of Undetermined Significance): This is the most common abnormal PAP smear result, and it can be caused by a variety of factors, including inflammation or infection 2. Next steps may include repeat PAP smear, HPV testing, or colposcopy.
- LSIL (Low-grade Squamous Intraepithelial Lesion): This stage indicates the presence of mild dysplasia, and next steps may include repeat PAP smear, HPV testing, or colposcopy 2.
- HSIL (High-grade Squamous Intraepithelial Lesion): This stage indicates the presence of moderate to severe dysplasia, and next steps may include colposcopy, biopsy, or loop electrosurgical excision procedure (LEEP) 3, 4, 5.
- CIN (Cervical Intraepithelial Neoplasia): This stage indicates the presence of precancerous cells, and next steps may include LEEP, cone biopsy, or other treatments 3, 4, 5.
Next Steps After Abnormal PAP Smear Results
After an abnormal PAP smear result, the next steps may include:
- Colposcopy: A procedure that uses a special microscope to examine the cervix for abnormal cells 3, 4, 5.
- Biopsy: A procedure that removes a sample of tissue from the cervix for further examination 3, 4, 5.
- LEEP: A procedure that removes abnormal cells from the cervix using a special wire loop 3, 4, 5.
- HPV testing: A test that checks for the presence of high-risk HPV types, which can cause cervical cancer 3, 4, 5, 2.
- Repeat PAP smear: A repeat PAP smear may be recommended to monitor the abnormal cells and ensure that they do not progress to a more severe stage 2.
Importance of Follow-up
Follow-up is crucial after an abnormal PAP smear result, as it can help detect any changes or progression of the abnormal cells 3, 4, 5. Regular follow-up appointments with a healthcare provider can help ensure that any necessary treatments are received, and that the risk of cervical cancer is reduced.
