Abstract

OBJECTIVE: The impact of pathologic features of a cone biopsy on the management of women with early stage cervical cancer is understudied. Our objective was to evaluate the additive value of pathologic features of a cone biopsy toward identifying patients with high risk tumors for which adjuvant therapy may be indicated.

METHODS: Patients with early stage cervical cancer undergoing a conization followed by radical hysterectomy from 1995 to 2016 were retrospectively identified. Clinical and pathologic data were abstracted from patient medical records.

RESULTS: A total of 115 patients were identified. Based on final pathology, 70.5% were low risk, 10.4% intermediate risk, and 19.1% were high risk. The additive pathologic features of the conization specimen would have reclassified five patients from low into the intermediate risk group. Though depth of invasion did not correlate with final pathology results, when lymphovascular space invasion (LVSI) was present in the conization specimen, 51.2% of patients were noted to meet intermediate/high risk; compared to only 9.5% without LVSI.

CONCLUSIONS: In women with early stage cervical cancer, additive pathology of the conization and hysterectomy specimen did not significantly impact risk stratification, only affecting 4.3% of patients. However, presence of LVSI in the conization was associated with intermediate risk criteria in 60% of cases and high risk criteria in 37% of cases. As patients with intermediate/high risk criteria would meet recommendations for adjuvant therapy, the evaluation of LVSI in conization specimens may influence the selection of primary treatment for women with cervical cancer.
