Surgical treatment and outcome of early invasive adenocarcinoma of the uterine cervix (FIGO stage IA1)

Abstract

Aim: To investigate the surgical outcome of FIGO stage IA1 cervical adenocarcinoma.

Methods: Between 2005 and 2011, 12 patients from Kyushu University Hospital had cervical adenocarcinoma, with a tumor depth of less than 3 mm and a horizontal width of less than 7 mm (FIGO stage IA1), diagnosed by cervical conization. All patients underwent simple hysterectomy or simple trachelectomy with pelvic lymphadenectomy.

Results: The mean patient age was 34 years (range, 26-70 years). The median follow-up period was 70.5 months (range, 26-99 months). No pelvic lymph-node metastasis was seen, and no patient experienced disease recurrence.

Conclusion: Early invasive cervical adenocarcinoma with a depth of invasion of 3 mm or less and a horizontal spread of 7 mm or less has little potential for nodal metastasis or recurrence. Therefore, simple hysterectomy or trachelectomy, without lymphadenectomy, might be an alternative treatment option for stage IA1 cervical adenocarcinoma.
