Kurzfassung:
Lymph node (LN) metastasis has been recognized as one of the most important factors for poor prognosis of esophageal cancer (EC). However, the influence of dissected LN number on metastatic detection rate and survival in EC has not been well documented. The present study was undertaken to correlate the total number of dissected LN, metastatic detection rate and survival on 10,382 EC patients. All the patients had been performed surgical treatment and confirmed as esophageal squamous cell carcinoma (ESCC) by histopathological examination. The patients were from Henan, Hebei and Shanxi provinces, the high incidence areas for EC in northern China, including 6,375 males with a mean age of 58±9 and 4,007 females with a mean age of 59±9. Of the patients, 2,714 cases have been followed up by interview at home until July, 2010. Eight EC groups had been classified based on the total number of dissected LN (1-3, 4-5, 6-7, 8-9, 10-11, 12-13, 14-16 and ≥17). The results showed that the positive metastatic detection rate apparently increased with the total extended dissected LN number (P & lt; 0.05) until reaching the level with a total of 17 or more dissected LN. 5-year survival analysis showed that the patients without LN metastasis had a higher survival rate than those with LN metastasis in all seven groups (P & lt;0.05) except the group with ≥17. Interestingly, the survival rate was similar in the group of ≥17 between the patients with positive or negative LN (P & gt;0.05). We concluded that the total dissected LN number could affect the survival rate for EC and that a total of 10 to 16 dissected LN should be recommended for EC surgical treatment.
