Abstract

Objective: To determine the incidence of parametrial involvement in a select group of patients with early cervical cancer.

Methods: We retrospectively reviewed the records of patients with cervical cancer and a maximum tumor diameter of 2 cm, infiltration depth<10 mm and negative pelvic lymph nodes who underwent a radical hysterectomy in two university hospitals. In addition, the literature was reviewed.

Results: 103 patients were identified in our databases that met the abovementioned criteria. In two of these patients (1.94%), parametrial involvement was found. Both patients had LVSI. Literature review revealed 696 patients described in three studies that satisfied the selection criteria. Three (0.43%) of these patients had parametrial involvement. In patients with early stage cervical carcinoma, tumor size<2 cm, infiltration depth<10 mm, negative pelvic lymph nodes and absent LVSI the risk of parametrial involvement is 0.63%.

Conclusion: Because of a very low risk on parametrial involvement, patients who fulfil strict selection criteria could be candidates for conization and pelvic lymphadenectomy instead of more extensive surgery. Morbidity and pregnancy complications may decrease while it is unlikely that survival will be compromised.
