Non-celiac gluten sensitivity (NCGS) is a term that is used to describe individuals who are not affected by celiac disease or wheat allergy, yet they have intestinal and/or extra-intestinal symptoms related to gluten ingestion with improvement of their symptoms upon withdrawing gluten from their diet. Gluten-related disorder groups are manifested by symptoms of gastrointestinal tract disorders, as well as hematological dermatological endocrinological, gynecological, rheumatological and nervous system symptoms. It is believed that NCGS represents heterogeneous groups with different subgroups characterized by different etiologies, clinical histories and clinical courses. There also appears to be an overlap between NCGS and irritable bowel syndrome (IBS). There is a need for establishing strict criteria for diagnosing NCGS. The absence of validated biomarkers remains a significant limitation for research studies on NCGS. New evidence shows that a gluten-free diet may be beneficial for some patients with gastrointestinal symptoms, such as those symptoms commonly found in patients with IBS. Further studies about NCGS are needed.

Background/Aims: This multicenter study reviewed the clinical features and prognosis according to the primary site of involvement and the treatment modality in patients with B-cell primary intestinal lymphoma (PIL). Methods: Among 125 consecutive patients diagnosed with PIL, 100 patients were analyzed. Results: The median age was 59 years, and the male to female ratio was 1.86:1. Diffuse large B-cell lymphoma (66/100, 66.0%) was the most common histological subtype. The estimated 5-year survival rate (5-YSR) was 48.5%. The 5-YSR was similar regardless of the type of primary treatment (chemotherapy alone vs. surgery/chemotherapy, 50.7 vs. 45.3%, p=0.582). A comparison of the survival according to the primary site of involvement revealed a 5-YSR of 32.5% (p=0.027), 64.3% (reference), 46.5% (p=0.113), and 49.8% (p=0.024) for the small intestine, ileocecal region, large intestine, and multiple sites, respectively. Multivariate analysis, however, revealed a low hemoglobin level, advanced Ann Arbor stage, and aggressive histological type to be independent prognostic factors for shorter survival but not ileocecal region involvement. Conclusions: The Ann Arbor stage, hemoglobin level, and histological type were independent prognostic factors for survival, while the primary site of involvement and treatment modality did not affect the prognosis in patients with B-cell PIL.

목적: 위장관 상피하병변에서 종양성 병변을 비종양성 병변으로부터 감별하는 것은 환자의 적절한 치료에 매우 중요하다. 저자들은 상부위장관 상피하병변 환자에서 종양성 상피하병변을 감별할 수 있는 예측인자를 알아보고자 이 연구를 수행하였다. 대상 및 방법: 2008년 1월부터 2013년 6월까지 경상대학교병원에서 상부위장관 상피하병변에 대해 EUS를 시행한 527예의 의무기록을 후향적으로 검토하여, 내시경적 또는 수술적 절제를 통하여 조직학적 확진이 가능했던 환자 84예를 선정하고, 종양 및 비종양성 상피하병변으로 분류하여 특성을 비교 분석하였다. 결과: 조직학적으로 확인된 84예의 상피하병변 중 상피하종양이 64예(76.2%), 비종양성 상피하병변은 20예(23.8%)였다. 상피하종양은 GIST (42.9%)와 평활근종(19.0%)이 가장 많았다. 성별(p=0.195), 병변의 크기(p=0.266), 에코상(p=0.051)은 상피하종양군과 비종양성병변군 사이에 유의한 차이가 없었다. 비종양성 상피하병변군에 비하여 상피하종양군의 평균연령 (p=0.047), 호발연령대(p=0.047) 및 50세 이상 환자의 비율 (p=0.015)이 높았으며, 고유근층 기원(79.7%)이 많았다. (p=0.001). 상피하종양 중, GIST는 평활근종보다 환자의 평균연령이 높고(57.7세 vs. 47.0세, p=0.049), 50세 이상 (p=0.016), 종양의 위체부 위치(p<0.001), 고유근층 기원 (p=0.003)이 많았다. 다변량분석에서 환자의 연령(≥50세), 종양의 크기(≥30 mm), 고유근층기원이 점막하종양의 독립적인 예측인자였고, 평활근종과 GIST의 감별인자는 찾을 수 없었다. 결론: 상부위장관 상피하병변으로 50세 이상, 30 mm 이상, 고유근층 기원이 상피하종양의 독립적인 예측인자였으며, 평활근종과 감별할 수 있는 GIST의 예측인자는 없으므로 고유근층 기원의 위 상피하종양은 GIST의 가능성을 고려하여 적극적인 치료 및 철저한 추적관찰이 필요하다. Background/Aims: Differentiating subepithelial tumor (SET) from non-neoplastic gastrointestinal subepithelial lesion (SEL) and gastrointestinal stromal tumor (GIST) from leiomyoma are very important for proper management. This study was conducted to analyze factors that could predict the presence of SET and GIST in patients with upper gastrointestinal (UGI) SELs. Methods: A total of 527 patients were diagnosed with UGI SELs endosonographically at Gyeongsang National University Hospital from January 2008 to June 2013. Among these patients, histologic diagnosis was made in 84 patients. Data were collected by retrospectively reviewing the medical records. Variables that could differentiate neoplastic from non-neoplastic SELs and GIST from leiomyoma were analyzed. Results: Among 84 patients with SELs, 64 (76.2%) had SETs including GIST (42.9%) and leiomyoma (19.0%). The patients` mean age (p=0.047), peak age distribution (p=0.047), proportions of patient ≥50 years (p=0.015), and number of proper muscle-originated lesions (p=0.001) were higher in neoplastic than non-neoplastic group. There were no significant differences in gender (p=0.195), size (p=0.266) and echogenicity (p=0.051) of the lesions. Older age (57.7 vs. 47.0 years, p=0.049), age ≥50 years (p=0.016), location in gastric body (p<0.001), and proper muscle origin (p=0.003) were significantly related to the presence of GIST compared to leiomyoma. Multiple regression analysis showed that the patients` age ≥50 years, size ≥30 mm, and proper muscle-origin of lesion were independent predictors of SET; however, there were no predictive factors that could differentiate GIST from leiomyoma. Conclusions: In patients with SEL, the possibility of having SET should be considered for patients ≥50 years with UGI SELs ≥30 mm that arise from the proper muscle. Thorough monitoring and aggressive management is warranted for those with gastric muscular SET since factors predictive of GIST are lacking. (Korean J Gastroenterol 2014;64:189-197)

Esophageal carcinosarcoma is a rare malignant esophageal neoplasm consisting of both carcinomatous and sarcomatous elements, with an incidence of 0.5%. There have been only a few case reports of carcinosarcoma and squamous cell carcinoma coexisting in the esophagus. However, all of these are cases of synchronous or metachronous development of carcinosarcoma after chemoradiotherapy in patients of esophageal squamous cell carcinoma. A 53-year-old man underwent esophagogastroduodenoscopy because of chest pain for several months. Endoscopic examination revealed a huge pedunculated esophageal polypoid mass. Endoscopic submucosal dissection (ESD) was performed and histopathologic examination confirmed spindle cell carcinoma (carcinosarcoma). He refused additional esophagectomy. After 21 months, third follow-up endoscopy showed poorly-demarcated flat, faint discolored lesions at different location from the previous ESD site and endoscopic biopsies confirmed squamous cell carcinoma. To the best of our knowledge, this is the first case of metachronous development of esophageal squamous cell carcinoma in a patient with esophageal carcinosarcoma.
