TOPLINE:
The frequency of follow-up after fertility-sparing surgery for cervical cancer can be tailored based on high-risk human papillomavirus (HPV) tests and cytology.
METHODOLOGY:
- Among patients with early-stage cervical cancer, the optimal follow-up strategy to detect recurrence after fertility-sparing surgery remains unclear. The authors wanted to find out if follow-up could be tailored to the patient's risk for recurrence instead of using the current inefficient one-size-fits-all approach.
- The retrospective cohort study, which used data from the Netherlands Cancer Registry and the Dutch Nationwide Pathology Databank, included 1462 patients aged 18-40 years with early-stage cervical cancer who received fertility-sparing surgery (large loop excision of the transformation zone, conization, or trachelectomy) between 2000 and 2020.
- The primary endpoint was the cumulative incidence of recurrent cervical intraepithelial neoplasia grade 2 or worse (CIN2+), including recurrent cervical cancer.
- The authors stratified the likelihood of recurrence by cytology and high-risk HPV results at the first follow-up visit within 12 months of fertility-sparing surgery; they also compared the cumulative incidence of recurrence — the number of new cases divided by all at-risk individuals over a specific interval — at four timepoints in 2 years (6, 12, 18, and 24 months).
TAKEAWAY:
- Overall, the 10-year recurrence-free survival for CIN2+ was 89.3%. Patients with high-grade cytology at the first follow-up had worse 10-year recurrence-free survival for CIN2+ (43.1%) than those who had normal (92.1%) and low-grade cytology (84.6%). Similarly for HPV status, patients positive for high-risk HPV at the first follow-up had worse 10-year recurrence-free survival rates for CIN2+ (73.6%) than those negative for high-risk HPV (91.1%).
- Patients negative for both high-risk HPV and high-grade cytology 6-24 months after fertility-sparing surgery had a cumulative incidence of recurrence of 0.0%-0.7% within 6 months of follow-up compared with 0.0%-33.3% among patients negative for high-risk HPV but who had high-grade cytology.
- By contrast, patients positive for high-risk HPV but not high-grade cytology had a cumulative incidence of recurrence of 0.0%-15.4% within 6 months of any follow-up visit compared with 50.0%-100.0% among those with both high-risk HPV and high-grade cytology.
- Patients who remained free of high-risk HPV and high-grade cytology at their 6-month and 12-month follow-ups had no disease recurrence over the next 6 months.
IN PRACTICE:
"Patients who are negative for high-risk HPV with normal or low-grade cytology at 6-24 months after fertility-sparing surgery could be offered a prolonged follow-up interval of 6 months," the authors concluded, adding that this "group comprises 80% of all patients receiving fertility-sparing surgery."
"Reducing the number of follow-up visits, and subsequently the number of follow-up tests, in patients with low risk for recurrence on the basis of co-testing has the potential to substantially reduce healthcare costs," the authors explained.
SOURCE:
The study, led by Teska N. Schuurman, MD, of the Netherlands Cancer Institute, Amsterdam, was published in the December 2023 issue of The Lancet Oncology.
LIMITATIONS:
The retrospective design of the study meant that analysis was limited to available records, so data on patients' symptoms, physical examinations, or colposcopic findings were not available. Follow-up biopsies, considered the gold standard for diagnosing recurrence, are not routine in the Netherlands, so recurrence could have been underreported.
DISCLOSURES:
The authors declared no competing interests.
