Cervical screening Flashcards
What is the frequency of cervical screening
Every 3 years from 25-49
Every 5 years from 50-64
No smear from 65, unless there was a previous abnormal result
What are the next steps if smear is normal and they are HPV -ve
Continue with routine screening
What are the next steps if smear is abnormal and they are HPV -ve
Refer for colposcopy
What are the next steps if smear is normal and they are HPV +ve
Re-test at 12 months
What are the next steps if smear is abnormal and they are HPV +ve
Refer for colposcopy
What are the next steps if a smear comes back as inadequate
Recall at 3 months
What are the next steps if a smear comes back as inadequate for the second time
Refer for colposcopy
What are the next steps if after testing HPV +ve, the patient tests HPV -ve after 12 months
return to routine screening
What are the next steps if after testing HPV +ve, the patient tests HPV +ve after 12 months but cytology remains normal
Repeat test 12 months later (24 months since first result)
What are the next steps if after testing HPV +ve, the patient tests HPV +ve after 12 months, then HPV +ve after another 12 months (24m)
Refer for colposcopy
In which women may cervical screening be omitted
Those without a cervix
Women who have never been sexually active (have very low risk of developing cervical cancer therefore they may wish to opt-out of screening)
How is cervical screening carried out during pregnancy
cervical screening in pregnancy is usually delayed until 3 months post-partum unless missed screening or previous abnormal smears.
Which women will have annual cervical cancer screening and why
Women at high risk of CIN/cervical cancer e.g. those with HIV
What other investigation should be done for women >35yo with suspected cervical cancer
Endometrial biopsy
What are the possible results from cervical cytology
- Normal
- Borderline nuclear changes HPV test → Urgent colposcopy <2w +ve colposcopy, -ve routine call
- Mild dyskaryosis (CIN 1) → HPV test → Urgent colposcopy <2w +ve colposcopy, -ve routine call
- Moderate dyskaryosis (CIN 2) → Urgent colposcopy <2w
- Severe dyskaryosis (CIN 3) → Urgent colposcopy <2w
- Invasive changes → Urgent colposcopy <2w
What is colposcopy
Colposcopy = use of a microscope and bright light source to visualise the transformation zone
Use of:
- Acetic acid to highlight abnormal areas of protein coagulation
- Lugol’s iodine which is taken up by normal cells due to high glycogen content
What are the benefits to the cervical screening programme
Programme is inexpensive, easy to administer, acceptable to patients and is valid/reliable/reproducible.
Prevents cervical cancer in those with HPV
What are the risks of the cervical screening programme
The exam can be very uncomfortable and sometimes painful for women
Not 100% sensitive and specific
Colposcopy can cause infection and bleeding
Those who undergo LLETZ will have an increased risk of pre-term deliveries if they become pregnant in the future
