Abstract

Objective

There is a gap in knowledge regarding the ideal management of patients with early-stage cervical cancer and intermediate-risk features. Here, we present a meta-analysis of the published literature on oncological outcomes in these patients and determine trends in postoperative management.

Methods

MEDLINE and PubMed were used for literature searches. The inclusion criteria were: English language articles including ≥ 10 patients, patients who underwent radical hysterectomy, nodes negative, studies reporting oncological outcomes and complications treatment-related and compare a surgery-only cohort with a radiotherapy cohort. The PRISMA guidelines were followed. Combined relative risk was calculated using DerSimonian–Laird random-effects model and a forest plot was drawn.

Results

We collected 183 manuscripts on early-stage cervical cancer treated with radical hysterectomy alone or with adjuvant radiotherapy after surgery. A total of eight studies met the inclusion criteria. Regarding oncological outcomes, survival was reported in five studies. The relative risk of recurrence and the relative risk of mortality was similar in both groups independently whether receive or not adjuvant therapy. Most of the studies did not report significant differences regarding morbidity treatment related between the groups, except for a higher rate of lymphedema after radiotherapy.

Conclusion

We found that the relative risk of recurrence and mortality was similar in both groups not depending on adjuvant therapy. Therefore, whether radiotherapy adjuvant treatment is indicated remains a topic of debate.
