Stage III endometrial cancer: analysis of prognostic factors and failure patterns after adjuvant chemotherapy.
OBJECTIVE
This study was performed to assess the prognostic factors and patterns of recurrence in stage III endometrial carcinoma treated with surgery and adjuvant chemotherapy.


METHODS
A retrospective review of 61 stage III endometrial carcinoma patients treated between 1988 and 1998 at Niigata University Hospital was performed. All patients underwent surgery, followed by adjuvant chemotherapy consisting of intravenous cisplatin, doxorubicin, and cyclophosphamide. Multivariate analysis was performed for the prognostic factors and actuarial techniques were used for the survival and recurrence rates.


RESULTS
The 5-year disease-free survival was 78.6%. Multivariate analysis revealed deep myometrial invasion and lymph-vascular space involvement correlated significantly with disease-free survival. Based on these two factors, the patients could be divided into low-risk and high-risk groups. The 5-year disease-free survival for the low-risk group was 100%, which was significantly better than the 59.1% for the high-risk group. Disease recurrence occurred in 13 of 30 high-risk patients, and there was no recurrence in the 31 low-risk patients. Looking at the patterns of recurrence for the high-risk group by lymph node metastasis, 5 recurrences were locoregional, 1 was locoregional/distant, and 1 was distant in 16 node-positive high-risk patients. In 14 node-negative patients, 5 had distant and 1 had locoregional/distant recurrences.


CONCLUSIONS
The locoregional failure in the node-positive high-risk group deserves further attention. For improvement of locoregional control, it may be worthwhile to consider new strategies. The role of new adjuvant chemotherapy should be investigated to control distant failure in node-negative high-risk patients.
