e14725 Background: Signet ring cell carcinoma (SRC) of the stomach is a histological type based on microscopic characteristics, and its clinicopathologic characteristics and treatment are still controversial. Methods: In this retrospective study, we reviewed the records of 68 patients diagnosed with gastric SRC treated between January 2007 and July 2011. The aim of this study is to identify the epidemiological, clinical and therapeutic features of this type cancer in a Moroccan population Results: In our study, SRC of the stomach represents 39 % of the gastric cancer and 11 % of all the digestif tract cancer. The mean age at the diagnosis was 46 years ranged from 25 to 80 years, 68 % were female. The clinical symptoms were vomiting (72%), epigastric pain (70%) and deterioration of Performans Status (93%). 73% of the patients were metastatic at the diagnosis, sites of metastasis were: peritoneum (85 %), lymphatic nodes (43 %), liver (35%), lung (28 %), ovaries (7 %), adrenal glands (7 %), bone (4 %) and the kidney (2 %). 23% of the patients had a localized disease and locally advanced 8%. Among the 64 patients, 27% were treated with curative intent by total gastrectomy followed by adjuvant concomittant chemoradiotherapy (n=6), adjuvant chemotherapy (n = 4) or perioperative chemotherapy (n=7). For the metastatic patients, chemotherapy regimens were distributed as following: ECC (Epirubicine 50 mg/m2, Cisplatine 60 mg/m2, Capecitabine 625 mg/m2/12h) was administred to 45 % of the cases, cisplatine-5FU to 18 % of the cases, capecitabine as monotherapy for 16 %; FUFOL Mayo clinic regimen for 9 % and EOX (Epirubicine 50 mg/m2, oxaliplatine 130 mg/m2, capecitabine 625 mg/m2/12h) for 5%. 7% of the patients were oriented to supportive care. A second line of chemotherapy was administed to 4 patients based on XELIRI (irinotecan 250 mg/m2 and capecitabine 2000mg/d for 14 days) in 3 patients and XELOX (oxaliplatine 85 mg/m2 and capecitabine 2,000mg/d for 14 days) in one patient (n = 1). Conclusions: The gastric Signet ring cell carcinoma represents an entity with specific characteristics, which tends more toward tumor invasion depth, with nodal and peritoneal metastases. Our results are consistent with those of the literature concerning the epidemiological finding and diagnosis aspects.
