Comparison of the 11 th Japanese classification and the AJCC 7 th and 8 th staging systems in esophageal squamous cell carcinoma patients
Although the American Joint Committee on Cancer (AJCC) staging system has been used worldwide for esophageal squamous cell carcinoma (ESCC), another staging system has been proposed by Japanese surgeons. The two systems have different lymph node maps, N staging, and stage grouping. This retrospectiv...

Zusammenfassung: | Although the American Joint Committee on Cancer (AJCC) staging system has been used worldwide for esophageal squamous cell carcinoma (ESCC), another staging system has been proposed by Japanese surgeons. The two systems have different lymph node maps, N staging, and stage grouping. This retrospective study compared the predictive ability of these two staging systems for survival.
We retrospectively reviewed records for 143 patients who underwent esophagectomy and mediastinal lymphadenectomy for ESCC from January 2006 to July 2015. Patients were staged by 7
, 8
AJCC stage and 11
Japanese classification. The concordance indexes (C-indexes) of these staging systems were compared.
Mean age was 63.14±8.10 years with 131 (91.6%) men. Median follow-up was 47.73 (6.27-134.40) months. All patients received R0 resection. Recurrences developed in 30 (20.9%) patients. Both AJCC N staging and Japanese N staging well predicted disease-free survival (DFS) (P |
