Gastric leiomyomas are rare submucosal neoplasms arising from smooth muscle cells.It accounts for approximately 2.5%of all gastric tumours,is slow growing and rarely causes symptoms such as upper abdominal discomfort and dyspepsia.1 On imaging,they appear similar to gastrointestinal stromal tumours(GISTs)and can be intraluminal or extraluminal.Diagnosis is mostly confirmed by histopathological examination of the tumour.Surgical resection of the tumour is the main treatment option.Here,we present a case of laparoscopic resection of an endophytic gastric tumour that turned out to be a leiomyoma. 展开更多

Mixed neuroendocrine non-neuroendocrine neoplasms(MiNENs)are a hetero-geneous group of malignant neoplasms that can settle in the gastroenteropan-creatic tract.They are composed of a neuroendocrine(NE)and a non-NE compo-nent in at least 30%of each tumour.The non-NE component can include different histological combinations of glandular,squamous,mucinous and sarcomatoid phenotypes,and one or both of the components can be low-or high grade malignant.Recent changes in the nomenclature of these neoplasms might lead to great deal of confusion,and the lack of specific clinical trials is the main reason why their management is difficult.The review aims to clarify the definition of MiNEN and analyze available evidence about their diagnosis and treatment options according to their location and extension through careful analysis of the available data.It would be important to reach a general consensus on their diagnosis in order to construct a classification that remains stable over time and facilitates the design of clinical trials that,due to their low incidence,will require long recruitment periods. 展开更多

BACKGROUND Pulmonary lymphoepithelioma-like carcinoma(PLELC)is a rare type of nonsmall-cell lung cancer.Stomach lymphoepithelioma-like carcinoma(LELC)metastasis secondary to PLELC has not been reported recently.CASE SUMMARY A 64-year-old female was admitted to our hospital for a regular gastroscopy examination with a 6-year history of surgical resection for left PLELC.Positron emission tomography/computed tomography suggested high accumulation of 18F-fludeoxyglucose in the gastric cardia region.Upper gastrointestinal endoscopy confirmed a large mass at the stomach fundus.Immunohistochemistry(IHC)of the biopsy suggested metastatic stomach LELC.Proximal gastrectomy showed that this 6.5 cm×5.0 cm mass was located in the stomach fundus near the cardia.Histopathological examination showed a poorly differentiated carcinoma with prominent lymphoplasmacytic infiltration.IHC demonstrated that the tumor was positive for CK(AE1/AE3),p63,p40,p53,Ki-67(70%),and EGFR(3+)and negative for CK7,CK20,Her2,and CD10.In situ hybridization analysis showed positive staining Epstein-Barr virus-encoded RNA.Tumor programmed cell death ligand 1(PD-L1)expression score was 98%,and the combined positive score was 100,with no evidence of microsatellite instability.Thus,the patient was unequivocally diagnosed with metastatic stomach LELC secondary to pulmonary LELC.After discharge,this patient underwent PD-1 inhibitor treatment(toripalimab,240 mg)every 3 wk for ten cycles,and she has had no tumor recurrence.CONCLUSION For gastric LELC metastasis,PD-1 inhibitor therapy could become a new therapeutic approach,though there is still no evidence from large data sets to support this. 展开更多

Stomach carcinoma is still the leading cause of cancer death in China and the second one in the world. Its possible causes include: A) chemical factors such as intragastric formation of N-nitroso compounds (NOC) and high salt intake; B ) biological factors such as infection of Helicobacter pylori and biotoxins intake; and C ) nutritional factors such as deficiency of vitamin C, selenium, and other antioxidants. Nitrogenous precursors of NOC, e.g., alkylamines, alkylureas, alkylguanidines, and alkylamides, occur widely in nature and potential nitrosating agents, e.g., nitrite (NO2-) and NOx (the gaseous oxides of nitrogen ) are similarly widespread. Relationship between exposure to NOC and causes of human cancer was investigated extensively ten years ago. Results indicated that the exposures of NOC might contribute to the occurrences of malignancy in the upper digestive tracts including stomachs. It was also observed that both high salt intake and deficiency of some micronutrients enhanced NOC-induced carcinogenicity. Recent studies show that infection of H. pylori can lead to atrophic gastritis and achlorhydria, and promote endogenous formation of NOC indirectly[1] . Much attention has been paid to stomach cancer and NOC regarding the characterization of natural N-nitrosamides in human environment in the 1990s. 展开更多

BACKGROUND Tumors located in the pylorus are technically more complex to resect by endoscopic resection,as the anatomical characteristics of this region can affect the adequate assessment of margins and performance of the procedure.We reported the results of underwater endoscopic mucosal resection(UEMR)of benign mucosal neoplasms located in the pyloric ring.CASE SUMMARY This case series describes 4 patients with 4 mucosal neoplasms located in the pyloric ring.The diameter of each neoplasm was less than 15 mm.We performed UEMR for the lesions.Water immersion enabled slight floating of the lesions,resulting in easy identification.We achieved en bloc resection with a snare and electrosurgical unit.All procedure were performed within 3 min without adverse events.Pathologic examination showed low-grade dysplasia with clear resection margins in one case and hyperplastic polyps in three cases.CONCLUSION UEMR can be an effective and safe treatment method for neoplasms in the gastric pyloric ring. 展开更多

Objective: To investigate the effect of different doses of recombined growth hormone (rhGH) on stomach neo- plasms implanted in nude mice, and its efficacy in combining with chemotherapy (flurouracil, 5-FU). Methods: Human stom- ach neoplasms model was established in nude mice. The nude mice were divided into control group, moderate-dose of rhGH group, low-dose rhGH group, 5-FU group, moderate-dose rhGH/5-FU group, and low-dose rhGH/5-FU group. The results of each group were observed after ten days. Results: After therapy, the body mass of rhGH groups was significantly increased compared with control group (P<0.05), the body mass of rhGH/5-FU groups was significantly increased compared with 5-FU group (P<0.05), but it was no significant difference between rhGH/5-FU groups and control group (P>0.05). The average tumor mass and volume of rhGH groups were not significantly increased compared with control group (P>0.05), but they were significantly reduced in 5-FU group and rhGH/5-FU groups (P<0.05). They were no significant difference between rhGH/5- FU groups and 5-FU group (P>0.05). After treatment, the percentages of S, G0/G1 and G2/M phases and proliferation index (PI) were not significantly changed in rhGH groups compared with control group (P>0.05), and the same with rhGH/5-FU groups compared with 5-FU group (P>0.05). The difference caused by dose of rhGH was not significant. Conclusion: rhGH enhances body mass, does not stimulate tumor growth, and has no adverse effects on tumor bearing nude mice. Combined with flurouracil, rhGH does not influence the efficacy of chemotherapy, and has no effect on tumor cell cycle kinetics. 展开更多

BACKGROUND Extraskeletal Ewing sarcoma(EES)is a rare and highly malignant small round cell tumor associated with a poor clinical outcome.Ewing sarcoma(ES)involving the stomach is an uncommon presentation and can be easily confused with other small round cell tumors.We herein present a rare case of ES involving the gastric area.CASE SUMMARY We report a case of gastric ES in a 19-year-old female patient who initially presented with a complaint of a tender epigastric mass for 5 d.Contrast-enhanced abdominal computed tomography revealed a soft-tissue-density mass with a diameter of 8.5 cm between the liver and stomach;the mass was connected to the gastric antrum.Then,the mass was surgically excised completely.Upon histopathological,immunophenotype and molecular analysis,the mass was identified to be a primary gastric ES.CONCLUSION EES is an aggressive tumor with poor prognosis.Therefore,early diagnosis and timely intervention are essential for a good prognosis.It is imperative for us to raise awareness about this rare tumor.Surgical resection is still the best treatment option. 展开更多

作者 李扬 年媛媛 孟宪梅 《胃肠病学》 2024年第1期3-9,共7页
背景:目前临床上尚无有效预测胃癌前病变进展或筛查早期胃癌的生物学标志物。目的:研究腺苷酸环化酶7(ADCY7)、G蛋白偶联受体GPR86、N⁃甲基⁃D⁃天冬氨酸离子能谷氨酸受体2D(GRIN2D)、G蛋白信号调节因子4(RGS4)在不同胃黏膜病变中的表达... 背景:目前临床上尚无有效预测胃癌前病变进展或筛查早期胃癌的生物学标志物。目的:研究腺苷酸环化酶7(ADCY7)、G蛋白偶联受体GPR86、N⁃甲基⁃D⁃天冬氨酸离子能谷氨酸受体2D(GRIN2D)、G蛋白信号调节因子4(RGS4)在不同胃黏膜病变中的表达及其对胃癌前病变进展的预测价值。方法:应用免疫组化法、real-time PCR和蛋白质印迹法检测ADCY7、GPR86、GRIN2D、RGS4在Correa级联各阶段(包括慢性非萎缩性胃炎、慢性萎缩性胃炎、低级别和高级别上皮内瘤变、黏膜层和黏膜下层早期胃癌)以及胃癌与相应癌旁组织间的表达差异。结果:ADCY7、GPR86、GRIN2D、RGS4在胃炎、上皮内瘤变、早期胃癌中的表达呈递增趋势,除GRIN2D在上皮内瘤变与早期胃癌中的表达无明显差异外,两两比较差异均有统计学意义(P均<0.001)。GPR86、GRIN2D mRNA和蛋白在胃癌组织中的表达显著高于癌旁>5 cm组织(P均<0.05);RGS4蛋白在胃癌组织中的表达高于癌旁>5 cm组织,其mRNA表达趋势则相反(P均<0.05);ADCY7仅蛋白表达在胃癌与癌旁>5 cm组织间差异显著(P<0.05)。结论:ADCY7、GPR86、GRIN2D、RGS4在Correa级联各阶段以及胃癌与相应癌旁组织间的表达变化提示其参与了胃癌前病变的发生、发展,可能具有预测胃癌前病变进展的价值。 展开更多
