RESUMEN

BACKGROUND: Gastrointestinal stromal tumours (GISTs) located in the jejunum or ileum (JI-GIST) are considered worse prognosis compared to those of gastric (G-GIST) location. It has been suggested that this dogma should be revised. The aim of this study was to describe the characteristics of jejunoileal GISTs and its prognosis and to compare them with G-GISTs in the era of imatinib. METHODS: We retrospectively reviewed the clinical histories of all the patients diagnosed with GISTs between January 2000 and November 2016: Clinical and pathological data, as recurrence, metastatic state, disease-free survival (DFS) as well as overall survival (OS) rates of patients were reviewed. RESULTS: JI-GIST patients comprise 29 cases (37.7%). Compared to G-GIST, JI-GIST patients had undergone emergency surgery more frequently (37.9% vs. 10.4%, p = 0.007). According to the NIH-Fletcher classification, the low or very-low risk group represents 17.2% of JI-GISTs as opposed to 37.6% of G-GISTs (p < 0.005). When the AFIP-Miettinen system was used the low or very-low group represented 17.2% of JI-GISTs vs. 58.4% in the G-GISTs group (p < 0.001). Both local recurrence (24.1% vs. 12.5%, p < 0.05) and metastatic rate (34.5% vs. 22.9%, p < 0.05) were higher in the JI-GIST group than in G-GIST. 5- and 10-year DFS and 10-year OS rate were lower for JI-GIST (54.5% and 39.6% vs. 77.2% and 60.8%, and 57.9% vs. 65%, respectively, p < 0.05). CONCLUSIONS: The observed differences between both groups in DFS and OS rates at long term could be attributed to the effect of imatinib.

RESUMEN

OBJECTIVE: To characterize the pattern of primary small bowel cancers in a tertiary East-European hospital. METHODS: A retrospective study of patients with small bowel cancers admitted to a tertiary emergency center, over the past 15 years. RESULTS: There were 57 patients with small bowel cancer, representing 0.039% of admissions and 0.059% of laparotomies. There were 37 (64.9%) men, mean age of 58 years; and 72 years for females. Out of 57 patients, 48 (84.2%) were admitted due to an emergency situation: obstruction in 21 (38.9%), perforation in 17 (31.5%), upper gastrointestinal bleeding in 8 (14.8%), and lower gastrointestinal bleeding in 2 (3.7%). There were 10 (17.5%) duodenal tumors, 21 (36.8%) jejunal tumors and 26 (45.6%) ileal tumors. The most frequent neoplasms were gastrointestinal stromal tumor in 24 patients (42.1%), adenocarcinoma in 19 (33.3%), lymphoma in 8 (14%), and carcinoids in 2 (3.5%). The prevalence of duodenal adenocarcinoma was 14.55 times greater than that of the small bowel, and the prevalence of duodenal stromal tumors was 1.818 time greater than that of the small bowel. Obstruction was the complication in adenocarcinoma in 57.9% of cases, and perforation was the major local complication (47.8%) in stromal tumors. CONCLUSION: Primary small bowel cancers are usually diagnosed at advanced stages, and revealed by a local complication of the tumor. Their surgical management in emergency setting is associated to significant morbidity and mortality rates.

RESUMO Objetivo Caracterizar o padrão de neoplasias malignas primárias do intestino delgado em um hospital terciário de Leste Europeu. Métodos Estudo retrospectivo de pacientes com câncer de intestino delgado, internados em um hospital terciário e de emergência, ao longo dos últimos 15 anos. Resultados Foram avaliados 57 pacientes com neoplasias malignas gastrintestinais, o que representou 0,039% das admissões e 0,059% das laparotomias realizadas. Total de 37 (64,9%) pacientes masculinos, média de idade de 58 anos, e de 72 anos para mulheres. Dentre os 57 pacientes, 48 (84,2%) foram internados em situação de emergência: obstrução intestinal em 21 (38,9%), perfuração em 17 (31,5%), hemorragia digestiva alta em 8 (14,8%), e hemorragia digestiva baixa em 2 (3,7%). Houve 10 (17,5%) tumores duodenais, 21 (36,8%) jejunais e 26 (45,6%) ileais. As neoplasias mais frequentes foram tumor estromal gastrintestinal, em 24 (42,1%) pacientes, adenocarcinoma em 19 (33,3%), linfoma em 8 (14%) e carcinoides em 2 (3,5%). A prevalência de adenocarcinoma duodenal foi 14,55 vezes maior do que a do intestino delgado, e a prevalência de tumores estromais duodenais foi 1,818 vez maior do que a do intestino delgado. A obstrução intestinal foi complicação do adenocarcinoma em 57,9% dos casos, e a perfuração foi a principal complicação local (47,8%) dos tumores estromais. Conclusão As neoplasias malignas primárias do intestino delgado foram geralmente diagnosticadas em estado avançado e reveladas por uma complicação local do tumor. O tratamento cirúrgico em situação de emergência está associado à significativa morbimortalidade.

RESUMEN

EBV-positive diffuse large B-cell lymphoma (DLBCL) in elderly is a new entity included provisionally in the most recent WHO Classification of lymphoid neoplasms. It usually affects elderly patients and has a poor survival. The goal of this report was to evaluate clinical, endoscopic characteristics and survival of five patients with this entity and gastrointestinal afectation. From five cases, three cases had gastric infiltration, one ileon and one in cecum.

RESUMEN

El Linfoma de Células Grandes B difuso del anciano asociado al Epstein Barr es una nueva entidad incluida provisionalmente en la más reciente clasificación de neoplasias linfoides de la WHO. Usualmente afecta ancianos y tiene pobre sobrevida. El objetivo de este reporte fue evaluar las característica clínicas, endoscópicas y sobrevida de cinco pacientes portadores de esta entidad y compromiso gastrointestinal. Tres casos tuvieron infiltración gástrica y dos casos tuvieron compromiso del ileón y el ciego.
