VENTURELLI M, FRANCISCO et al. Survival of patients with signet ring cell carcinoma of the stomach, compared with patients with non ring cell gastric cancer. Rev Chil Cir [online]. 2008, vol.60, n.5, pp. 398-402. ISSN 0718-4026. doi: 10.4067/S0718-40262008000500006.
Background: Signet ring cell (SRC) carcinoma of the stomach corresponds to 3 to 39% of all cases of gastric cancer. It tends to be less differentiated, infiltrative and diffuse. It is not clear if it has a different prognosis than other types of gastric cancer. Aim: to compare the survival of SRC gastric carcinoma with other types of gastric cancer, considering depth of gastric wall involvement and number of infiltrated lymphnodes. Material and Methods: Retrospective review of pathology samples of all gastric cancers operated between 1988 and 2005. Survival of patients with and without SRC gastric cancer was compared. Results: A total of 287 cases were reviewed. Of these 60 had a SRC gastric cancer. No differences in gastric wall infiltration between SRC and non SRC gastric cancer was observed. SRC gastric cancer has a higher frequency of lymph node involvement. No differences in survival between SRC and non SRC gastric cancer, were observed. Conclusions: In this retrospective series of patients, no differences in survival were observed between SRC and non SRC gastric cancer.
