BACKGROUND: The risk of developing a second neoplasm in a person with gastric carcinoma (GC) is higher than among general population. OBJECTIVE: To analyze the clinical findings in patients with GC associated with other primary malignant neoplasms. PATIENTS AND METHODS: A total of 25 patients with GC associated with extragastric tumours were retrospectively studied. The following characteristics were studied: age, sex, location and staging, free interval, therapy, and survival. Survival of 13 patients with GC diagnosed as primary tumour was compared with that observed in a control group of 62 patients with GC alone. RESULTS: Twenty-five out of 792 (3.1%) patients with GC had other primary malignant neoplasms (seven synchronous and 18 metachronous). GC was associated with respiratory tumours in 7 cases. Sixty percent of patients with GC who had a second neoplasm had it diagnosed within the first year after gastric tumour was diagnosed (8 out of 13). Survival at 18 months was similar, both in the GC group with a second tumour as in the control group. CONCLUSIONS: The development of a second neoplasm among patients with GC usually occurs within the first year after diagnosis. Most commonly, the second neoplasm seats in the respiratory tract.
