Abstract:
OBJECTIVE: The aim of this study was to investigate the risk and recurrence of early invasive adenocarcinoma of the cervix, and to determine whether non-radical methods of management could be performed. METHODS: The medical and histopathological records of 50 patients with early invasive adenocarcinoma of the cervix treated at Keio University Hospital between 1993 and 2005 were reviewed, and compared with the literature. RESULTS: The median follow-up period was 64.3 months. The depth of stromal invasion was < or =3 mm in 33 cases and >3 mm, but < or =5 mm in 17 cases. The horizontal spread was < or =7 mm in 25 cases and >7 mm in 25 cases. One of the 33 cases that had tumor volumes of < or =500 mm3, and three of the 17 cases with tumor volumes of >500 mm3 were positive for lymph node metastasis. When our data were combined with previously reported results, statistically significant differences were observed between the tumor volume and the frequency of pelvic lymph node metastasis/the rate of recurrence (p<0.0001). The frequency of pelvic lymph node metastases was significantly higher in the lymphovascular space invasion (LVSI)-positive group than in the LVSI-negative group (p=0.02). No adnexal metastasis or parametrial involvement was noted. CONCLUSION: Assessment of the depth of stromal invasion, tumor volume, and LVSI is critical for selecting an appropriate therapeutic modality. Non-radical methods of management are considered suitable for patients with LVSI-negative adenocarcinoma of the cervix exhibiting a stromal invasion depth of < or =5 mm and a tumor volume of < or =500 mm3.
