Abstract

Background

The 7th edition of the American Joint Committee on Cancer (AJCC) cancer staging manual incorporates tumor grade and location for staging pT2–3N0M0 esophageal squamous cell carcinoma. Patients with pT3N0M0, classified as stage IIa according to the 6th edition of the AJCC cancer staging manual, can now be classified as stage Ib, IIa, or IIb. We aimed to discuss whether these changes affect survival and determine other potential prognostic factors.

Methods

We retrospectively analyzed 302 patients with postoperative pathologic stage T3N0M0 who underwent esophagectomy between 1990 and 2005 at Sun Yat-sen University Cancer Center. We performed univariate and multivariate analyses to identify prognostic factors for survival and used the Kaplan–Meier method to compare survival difference in each prognostic factor, including tumor grade and location.

Results

The 5-year overall survival rate was 46 %, with a median survival of 1,244.5 days. Gender, age, alcohol consumption, forced expiratory volume in 1 s (FEV1), and number of removed lymph nodes were independent prognostic factors in both univariate and multivariate analyses. Smoking was also a prognostic factor in survival analysis by the Kaplan–Meier method. However, histologic tumor grade and location had no significant influence on patient survival.

Conclusions

Age, gender, alcohol consumption, FEV1, number of removed lymph nodes, and cigarette smoking are independent prognostic factors in patients with pT3N0M0 esophageal squamous cell carcinoma. However, tumor grade and location may not be as strong predictors in these patients as indicated in the 7th edition of the AJCC cancer staging manual.
