Purpose: This study clarifies age differences in clinicopathologic characteristics and risk factor exposure of patients who have undergone esophagectomy for esophageal cancer (EC).
Methods: Clinical results of esophagectomy were compared between 22 patients younger than 50years of age (Group I) and 327 patients older than 50 years of age (Group II) with esophageal squamous cell carcinoma.
Results: The two groups did not significantly differ in clinicopathological characteristics, including prognosis. Postoperative pulmonary complication incidence rates were 4.2% (Group I) and 14.4% (Group II). In Group I, the incidence of multiple ECs was 36.4%, and association with head and neck cancer was 31.8%, which were significantly higher than in Group II (13.4%, p=0.021; and 9.2%, p=0.015, respectively). Furthermore, the patients in Group I with multiple cancers were almost all heavy smokers and/or users of alcohol.
Conclusions: These results suggest that multiple upper aerodigestive tract cancers are associated with heavy exposure to risk factors in patients younger than 50years of age.
