Objective
While it is known that positive surgical margins increase the risk of cervical cancer recurrence, little is known about the effect of close surgical margins (CSM). Therefore, we set out to determine the impact of margin status on recurrence and survival in patients with early-stage cervical cancer.
Methods
A retrospective review was conducted of patients undergoing radical hysterectomy from 2000 to 2010 with Stage IA2-IIA cervical cancer. CSM were defined as ≤5 mm; association with other clinicopathologic factors as well as recurrence and survival was evaluated.
Results
Of the 119 patients, 75 (63%) with CSM had a recurrence rate of 24% compared to 9% without CSM. Though not independently associated with recurrence, CSM were significantly associated with positive lymph nodes (44% vs. 18%), positive parametria (33.3% vs. 2.3%), larger tumors (3.5 vs. 2.5 cm), greater depth of stromal invasion (DOI) (84% vs. 33%), and lymphovascular space invasion (LVSI) (61.3% vs. 34.1%). We failed to find an association between adjuvant therapy and recurrence in those with CSM. Exploratory analysis revealed that a surgical margin of ≤2 mm was significantly associated with an increased risk of overall recurrence (36% vs. 9%, p=0.009) as well as loco-regional recurrence (22% vs. 4%, p=0.0034).
Conclusions
Surgical margins of ≤5 mm on radical hysterectomy specimens are often associated with other high or intermediate risk factors for recurrence. While not a proven independent risk factor, the distance to surgical margin may warrant further investigation as an intermediate risk factor along with tumor size, DOI and LVSI.
Quantitative and emerging qualitative outcomes highlight that fellows are professional and are largely able to evaluate and care for patients but that achieving independence, surgical skills, and scholarship requires further training.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
