Kaplan-Meier survival curves comparing months of survival in gastric adenocarcinoma (AC) and signet ring cell carcinoma (SRC) are shown for (A) all stages, (B) American Joint Committee on Cancer, 6th edition (AJCC) stage 1 tumors, (C) AJCC stage 2 tumors, (D) AJCC stage 3 tumors, and (E) AJCC stage 4 tumors. Median survival for AJCC stage 1 tumors is not shown because more than 50% of patients had censored data for survival.
