Background: Stomach cancer has one of the highest incidences worldwide. In Peru, there is no adequate record and report of cases, which allows an evaluation of the classic and new factors described in the literature, as well as factors typical of carcinoma. Objective: To determine the association between the development of metastasis in patients with gastric adenocarcinoma and the histopathological pattern in signet ring cell. Materials and Methods: We conducted a case-control study at the National Institute of Neoplastic Diseases (INEN) in patients diagnosed with stomach cancer. It was defined as case, to any patient who developed metastases and as a control, that patient who did not develop metastases, our exposure of interest was the type of adenocarcinoma. Results: We evaluated a total of 174 cases and 93 controls. The average age in cases and controls was 58.8 and 58.6, respectively. The majority of cases (86,78%) and controls (61,29%) were diagnosed in advanced stages (greater than 2). Likewise, it was evidenced that the cases presented a greater possibility 5.57 times (IC 95%: 1.76 - 17.62) of having presented the seal ring subtypes in conjunction with other histological subtypes compare to the controls. Conclusions: In patients with gastric cancer who developed metastases, the finding of the signet ring pattern is not a factor associated with the negative prognosis. On the contrary, we can affirm that in people with gastric cancer who developed metastases it is likely that they have presented some histological pattern that has co-existed with the adenocarcinoma subtype in the seal ring.
