abstract = {Background: To evaluate the clinical characteristics and prognostic factors of esophageal carcinoma (EC) with multiple primary carcinomas (ECWMPC).
Methods: Clinical and survival data of 268 ECWMPC patients with two different primary carcinomas and 9,101 individual EC patients taken from hospital records dating from January 1996 to December 2012 were analyzed retrospectively.
Results: There were a total of 11,066 EC patients treated over this period of which 330 patients met the diagnostic criteria of ECWMPC. Two hundred and sixty-eight patients who had two different primary carcinomas and survival data were recruited in this analysis. The median age of the first carcinoma occurrence was 59 (31 to 85) years old, and the median age of the second carcinoma occurrence was 62 (32 to 86) years old, with a male to female ratio of 6:1. The predilection sites were located in the head and neck, followed by the gastric-esophageal junction. For the subgroup of synchronous ECWMPC (S-ECWMPC) and metachronous ECWMPC (M-ECWMPC), head and neck remain the popular site of S-ECWMPC but cardiac became the top of the M-ECWMPC. More breast and colon rectum disease were found in S-ECWMPC patients. The ECWMPC patients had a significantly lower median survival time (MST) and 1, 3, and 5 years overall survival (OS) than the single EC patients [12.4 months and 51.8%, 21.9%, 14.7% vs. 17.0 months and 59.4%, 31.3%, and 23.9% (P},
