Abstract

We analyzed lymph node metastasis in 38 cervical esophageal cancer patients who received curative operations at Kurume University Hospital between 1989 and 2003. The following results were obtained. 1) The frequency of lymph node metastasis in each area was No. 101: 18 (47%) patients, No. 102: 9 (24%) patients, No. 104: 9 (24%) patients, and No. 106rec: 8 (21%) patients. 2) The prognosis of patients who had metastatic lymph nodes in more than 3 segmented areas was poor. 3) Distant metastasis was detected in 4 (67%) of 6 patients whose number of metastatic lymph nodes exceeded 4. In contrast, 5 (16%) of 32 patients whose metastatic lymph nodes numbered less than 3 had distant metastasis. There was thus a statistically significant difference in the rate of distant metastasis (p=0.007) between the two groups. 4) Distant metastasis was detected in 7 (41%) of 17 patients whose regions of metastatic lymph nodes numbers more than 2. In contrast, 2 (10%) of 21 patients with one or no metastatic region had distant metastasis (p=0.02). 5) Distant metastasis was detected in 8 (44%) of 18 patients whose metastatic lymph nodes showed extra-capsular spread. In contrast, distant metastasis was found in only 1 (5%) of 20 patients without extra-capsular spread (p=0.004). These results indicated that postoperative treatments such as adjuvant chemotherapy are highly recommended in patients whose number of metastatic lymph nodes exceeds 4, whose regions of metastatic lymph nodes number more than 2, and whose metastatic lymph nodes show extra-capsular spread.
