ABSTRACT

El cáncer gástrico (CG) es la neoplasia del tubo digestivo más prevalente en el mundo, asociada a factores genéticos del hospedero y externos, como infección por Helicobacter pylori. La patogénesis incluye inflamación crónica mediada por citocinas del microambiente tumoral, detectables sistémicamente. Estudios previos reportan niveles séricos de citocinas y su contribución al diagnóstico de CG. El presente estudio analiza el perfil de citocinas del tipo de Th1(IFNγ), Th2(IL-4 e IL-10), Th17(Th-17A) y otras pro inflamatorias: IL-1ß, IL-6 y TNF-α, en plasma de 70 casos de pacientes con CG comparándolos con 132 sujetos sanos equiparables en edad y sexo. Los casos provinieron del Hospital Roosevelt e Instituto Nacional de Cancerología de Guatemala (Incan) y formaron parte de un estudio previo. Se analizó la base de datos clínicos, patológicos y epidemiológicos. Se midieron los niveles de citocinas utilizando el sistema "MSD MULTI-SPOT Assay System". La edad promedio de los casos fue 59.5 años, (DE 13.0), 51%, eran positivos para IgG anti H. pylori. Un 71% presentó adenocarcinoma grado III (Borrman), según clasificación de Lauren 55% tenían tipo intestinal. Las siete citocinas cuantificadas se encontraron significativamente elevadas (p < .05) en el plasma de los casos respecto a sus controles. Los casos de CG tipo difuso presentaron niveles de IFNγ significativa-mente elevados. Por regresión logística, las citocinas IL-6 e IL-10, están asociadas significativamente a CG (p < .05) independientemente del estatus de infección por H. pylori. Se destacan la IL-6 e IL-10 como las principales citocinas asociadas a la presencia de CG.


Gastric cancer (GC) is the most prevalent gastrointestinal neoplasm in the world, associated with host and external genetic factors, such as Helicobacter pylori infection. The pathogenesis includes chronic inflammation mediated by cytokines of the tumor microenvironment, systemically detectable. Previous studies report serum levels of cyto-kines and their contribution to the diagnosis of GC. The present study analyzes the profile of cytokines of the type Th1 (IFNγ), Th2 (IL-4 and IL-10), Th17 (Th-17A) and other pro-inflammatory: IL-1ß, IL-6 and TNF-α, in plasma of 70 cases of patients with GC compared with 132 healthy subjects comparable in age and sex. The cases came from the Roosevelt Hospital and the National Cancer Institute of Guatemala -Incan- and were part of a previous study. The clinical, pathological and epidemiological databases were analyzed. Cytokine levels were measured using the "MSD MULTI-SPOT Assay System". The average age of the cases was 59.5 years, (SD 13.0), 51% were positive for IgG anti H. pylori, 71% had grade III adenocarcinoma (Borrman), according to Laurenís classification, 55% had intestinal type. The seven cytokines quantified were found to be significantly elevated (p < .05) in the plasma of the cases compared to their controls. The diffuse GC cases presented significantly elevated IFNγ levels. By logistic regression, the cytokines IL-6 and IL-10 are significantly associated with GC (p < .05) regardless of the H. pylori infection status. IL-6 and IL-10 stand out as the main cytokines associated with the presence of GC.

ABSTRACT

Tumor lysis syndrome is a well-characterized and potentially deadly complication of spontaneous or treatment-related tumor destruction, and it is most commonly associated with hematologic malignancies. Our case illustrates a rare example of fatal tumor lysis syndrome in the setting of metastatic gastric adenocarcinoma treated with radiation therapy. This case highlights the critical importance of identifying patients with solid organ malignancies at risk for tumor lysis syndrome and of early recognition and treatment of this syndrome.

ABSTRACT

RESUMEN Introducción: en los últimos años, se aprecia a nivel global un aumento del cáncer gástrico. La mayoría de los tumores gástricos primarios son malignos. En Matanzas, existe un incremento de esta patología. Objetivo: determinar el comportamiento clínico, endoscópico e histológico del cáncer gástrico diagnosticado. Materiales y métodos: se realizó un estudio observacional, descriptivo y prospectivo en el Departamento de Gastroenterología del Hospital "Dr. Mario Muñoz Monroy", de la ciudad de Matanzas, en el período de enero del 2017 a octubre del 2019. El universo fue 25 pacientes que presentaron cáncer gástrico por diagnóstico endoscópico e histológico. Resultados: el grupo de edad más afectado correspondió a los pacientes entre 61 y 70 años, (44 %). El sexo masculino predominó en un 68 %. Los factores de riesgo de mayor incidencia, fueron la dieta inadecuada y el hábito de fumar. Las manifestaciones clínicas más relevantes fueron: epigastralgia, plenitud gástrica y pérdida de peso. La variedad hística que predominó fue el adenocarcinoma difuso y la localización el antro. Conclusiones: el cáncer gástrico constituye un problema de salud que, al actuar sobre los factores de riesgo se puede disminuir su incidencia; con un diagnóstico precoz se logrará disminuir la mortalidad (AU).


ABSTRACT Introduction: an increase of gastric cancer is appreciated in the world in the last years. Most of the primary gastric tumors are malignant. There is an increase of this disease also in Matanzas. Objective: to determine the histological, endoscopic and clinical behavior of the diagnosed gastric cancer. Materials and methods: a prospective, descriptive and observational study was carried out in the Department of Gastroenterology of the Hospital "Mario Munoz Monroy, of Matanzas, in the period from January 2017 to October 2019. The universe were 25 patients presenting gastric cancer by histologic and endoscopic diagnosis. Results: The most affected age group was the one of patients among 61 and 70 years old (44 %). Male sex predominated in 68 %. The risk factors having higher incidence were an inadequate diet and smoking. The more relevant clinical manifestation were epigastralgia, gastric fullness and weight loss. The predominating tissue variety was the diffuse adenocarcinoma and antrum location. Conclusions: gastric cancer is a health problem the incidence of which could be reduced when acting on its risk factors; with a precocious diagnosis mortality will be reduced (AU).

ABSTRACT

Se denomina mieloptisis a la infiltración de la médula ósea por células no hematopoyéticas. En pacientes con cáncer gástrico esta invasión es extremadamente infrecuente y la supervivencia suele ser menor a tres meses. Presentamos el caso de un hombre de 35 años con compromiso de la médula ósea secundario a un carcinoma gástrico difuso de células en anillo de sello.


The infiltration of the bone marrow y non-hematopoietic cells is called myelophthisis. In patients with gastric cancer, this invasion is extremely infrequent and the survival is usually less than three months. We present the case of a 35-year-old man with bone marrow involvement secondary to diffuse gastric carcinoma of signet ring cells.

ABSTRACT

Malignant-or-paraneoplastic acanthosis nigricans is a verrucous and hyperpigmented tumor affecting the mucosa and skin. In most cases malignant acanthosis nigricans is a distant manifestation of an intra-abdominal primary cancer. While the diagnosis of malignant acanthosis nigricans is challenging, some specific clinical and histopathological findings could lead to an accurate diagnosis. A rare clinical case of a 59-year-old female, who was referred to the maxillofacial surgery service due to a painful oral lesion in the palatine region, is presented. Upon examination, papillomatous lesions were observed on the hard palate, that were later diagnosed as intraoral malignant acanthosis nigricans secondary to gastric cancer. Both local and systemic evaluations are discussed, highlighting the relevance of a multidisciplinary approach consistent with the fact that these manifestations, although infrequent, should generate suspicion among clinicians and therefore motivation to perform a diligent and complete study since it can reveal the presence of a malignant pathology.


La acantosis nigricans maligna o paraneoplásica es un tumor verrugoso e hiperpigmentado que afecta la mucosa y la piel. En la mayoría de los casos, la acantosis nigricans maligna es una manifestación distante de un cáncer primario intraabdominal. Si bien el diagnóstico de acantosis nigricans maligna es desafiante, algunos hallazgos clínicos e histopatológicos específicos podrían conducir a un diagnóstico preciso. Se presenta un caso clínico raro de una mujer de 59 años, que fue derivada al servicio de cirugía maxilofacial debido a una lesión oral dolorosa en la región palatina. En el examen, se observaron lesiones papilomatosas en el paladar duro, que posteriormente se diagnosticaron como acantosis nigricans maligna intraoral secundaria a cáncer gástrico. Se discuten tanto las evaluaciones locales como las sistémicas, destacando la relevancia de un enfoque multidisciplinario consistente con el hecho de que estas manifestaciones, aunque poco frecuentes, deberían generar sospecha entre los clínicos y, por lo tanto, motivación para un estudio diligente y completo, ya que puede revelar la presencia de una patología maligna.

ABSTRACT

La endocarditis trombótica no bacteriana, antiguamente conocida como endocarditis marántica, es una entidad infrecuente en la que se desarrollan vegetaciones estériles, compuestas por fibrina en las válvulas del corazón. Suele diagnosticarse en el momento de la autopsia o en enfermedades oncológicas avanzadas. Las neoplasias malignas más frecuentemente asociadas con esta entidad son las de pulmón, páncreas, estómago y adenocarcinomas de origen primario desconocido. Es necesario descartar la endocarditis infecciosa y establecer la presencia de vegetaciones valvulares mediante ecocardiografía. Presentamos el caso de una paciente con diagnóstico reciente de adenocarcinoma de estómago en estadio avanzado que presentó ceguera cortical e imágenes compatibles con isquemia cerebral. El ecocardiograma transesofágico mostró dos vegetaciones en válvula mitral. Los hemocultivos fueron negativos. Se enfatiza la importancia de sospechar endocarditis trombótica no bacteriana en enfermos con cáncer y embolismo sistémico.


Nonbacterial thrombotic endocarditis, formerly known as marantic endocarditis, it is an infrequent entity in which sterile, fibrin vegetations develop on heart valve leaflets. It is often diagnosed at the time of autopsy or in late-stage malignancies. The most common malignancies associated with nonbacterial thrombotic endocarditis are lung, pancreatic, gastric cancer and adenocarcinomas of an unknown primary site. Diagnosis requires ruling out infective endocarditis and establishing the presence of valvular vegetations using echocardiography. We report the case of a patient with a recent diagnosis of advanced gastric adenocarcinoma who presented with cortical blindness. The computed tomography was compatible with cerebral ischemia. The transoesophageal echocardiogram showed two vegetations in mitral valve. Blood cultures were negative. We emphasize the importance of suspecting nonbacterial thrombotic endocarditis in patients with cancer and systemic embolism.

ABSTRACT

ABSTRACT CONTEXT: Non-islet-cell-tumor-induced hypoglycemia (NICTH) is caused on rare occasions by secretion of insulin from tumor cells that are reported to have a single tissue origin. CASE REPORT: A 67-year-old male patient had cardia adenocarcinoma and concomitant lung adenocarcinoma with extensive metastases and repeated episodes of intractable hypoglycemia. Immunohistochemical staining for insulin showed that lung adenocarcinoma stained positive and gastric cardia adenocarcinoma stained weakly positive. These results indicate that tumor cells of different tissue origins co-secreted insulin. CONCLUSIONS: This is the first report on intractable hypoglycemia due to co-secretion of insulin from two kinds of primary tumor cells in a single patient.

ABSTRACT

El lipoma gástrico (LG), es un tumor benigno raro que representa el 5 % de los lipomas gastrointestinales y menos del 1 % de todos los tumores gástricos. Se localizan habitualmente a nivel de la submucosa y generalmente en la región antral. La endoscopia y la tomografía computarizada son las herramientas diagnósticas más utilizadas en el proceso diagnóstico. Dada su relativa rareza, quedan a menudo fuera del diagnóstico diferencial de las masas submucosas gastrointestinales superiores. El objetivo de este manuscrito, es reportar dos casos tratados de forma consecutiva y revisar la literatura existente en esta materia. Se trata de dos pacientes de sexo masculino, de 49 y 69 años de edad, a quienes se diagnosticó una lesión submucosa gástrica por endoscopia y fueron tratados quirúrgicamente y cuyos especímenes fueron estudiados histológicamente, concluyéndose en ambos casos la existencia de un LG. Ambos pacientes evolucionaron de forma correcta y permanecen en controles clínicos y endoscópicos hasta la actualidad, sin inconvenientes. El LG es una entidad poco común, que puede simular una enfermedad maligna. Presentamos dos casos tratados quirúrgicamente con resultados satisfactorios.


Gastric lipoma (GL), is a rare benign tumor that represents 5 % of gastrointestinal lipomas and less than 1 % of all gastric tumors. They are usually located at the level of the submucosa and usually in the antral region. Endoscopy and computed tomography are the diagnostic tools most used in the diagnostic process. Given their relative rarity, they are often left out of the differential diagnosis of the upper gastrointestinal submucosal masses. The aim of this manuscript was to report two cases treated consecutively and review the existing literature on this subject. Two male patients, 49 and 69 years of age, were diagnosed with a gastric submucosal lesion by endoscopy and were treated surgically. The specimens were studied histologically; concluding the existence of a GL in both cases. The two patients evolved adequately and have remained in clinical and endoscopic controls until now, without problems. GL is a rare entity, which can simulate a malignant disease. We present two cases treated surgically with satisfactory results.

ABSTRACT

Abstract Introduction and objectives: Quadratus Lumborum block was recently described and has already shown good results as an analgesic technique in abdominal surgeries, having the potential to significantly reduce opioids consumption and be a valid alternative to epidural catheter. We performed a type II Quadratus Lumborum block for analgesia in a septic patient having a sub-total gastrectomy. Case report: An 80 year-old, ASA III, male patient, weighting 50 kg, with a history of arterial hypertension and hypercholesterolemia, diagnosed with sepsis due to purulent peritonitis was submitted to an open laparotomy. Bilateral ultrasound-guided type II Quadratus Lumborum block was performed before surgery, using 10 mL of levobupivacaine 0.25% and 5 mL of mepivacaine 1%, per side. Pain relief was achieved 5 minutes after injection and the patient referred no pain in the immediate postoperative period. Discussion: Type II Quadratus Lumborum block may be considered a valid alternative for postoperative analgesia in a septic patient undergoing major abdominal surgery with some relative contraindications to epidural catheter placement. It allowed us to achieve excellent pain management avoiding opioids usage. However, more reports are still needed to properly access its usefulness.


Resumo Introdução e objetivo: O bloqueio do quadrado lombar (QL) foi descrito recentemente e já mostrou bons resultados como técnica analgésica em cirurgias abdominais, com potencial para reduzir significativamente o consumo de opioides e ser uma opção válida ao cateter peridural. Fizemos um bloqueio do QL tipo II para analgesia em um paciente séptico para gastrectomia subtotal. Relato de caso: Paciente do sexo masculino, 80 anos de, ASA III, 50 kg, com história de hipertensão arterial e hipercolesterolemia, diagnosticado com sepsis devido a peritonite purulenta, foi submetido a uma laparotomia aberta. O bloqueio bilateral do QL tipo II guiado por ultrassom foi feito antes da cirurgia com 10 mL de levobupivacaína a 0,25% e 5 mL de mepivacaína a 1%, por lado. O alívio da dor foi obtido em 5 minutos após a injeção e o paciente não referiu dor no pós-operatório imediato. Discussão: O bloqueio do quadrado lombar (QL) tipo II pode ser considerado uma opção válida para analgesia no pós-operatório em um paciente séptico submetido a cirurgia abdominal de grande porte, com algumas contraindicações relativas à colocação do cateter peridural. Permitiu-nos obter um excelente manejo da dor e evitar o uso de opioides. Contudo, mais relatos ainda são necessários para avaliar corretamente a sua utilidade.

ABSTRACT

Introducción: Los pólipos gástricos adenomatosos son poco frecuentes y generalmente se encuentran en el examen endoscópico de rutina. La intususcepción gastroduodenal es una complicación poco frecuente de los pólipos gástricos y ha sido raramente descrita como una causa de pancreatitis aguda. Caso clínico: Presentamos el caso de un varón de 68 años el cual ingresa de urgencia con dolor abdominal, náuseas y vómitos catalogados en un inicio como pancreatitis aguda de etiología biliar; incidentalmente se descubre un pólipo gástrico pediculado intususceptado a duodeno como causa de la pancreatitis aguda. Se realizó tratamiento endoscópico de urgencia y tratamiento definitivo con cirugía abierta.


Introduction: Adenomatous gastric polyps are uncommon and are usually found in the routine endoscopic examination. Gastroduodenal intussusception is a rare complication of those gastric polyps and has rarely been described as a cause of acute pancreatitis. Case report: We present the case of a 68 year old man who admitted to emergency with abdominal pain, nausea and vomiting initially classified as acute biliary pancreatitis etiology; a pedunculated gastric polyp intussuscepted into duodenum as a cause of acute pancreatitis was incidentally discovered, emergency endoscopic treatment and definitive treatment with open surgery was performed.

ABSTRACT

Summary Perforated gastric carcinoma is a rare condition that is hard to diagnose preoperatively. It is associated with advanced cancer stages and has a high mortality, particularly in cases presenting preoperative shock. Few studies have investigated the presentation and adequate management of these carcinomas. In addition, there are no reports in the literature on perforations extending to the spleen, as described in this case, making the management of these lesions challenging. Our article reports a case of gastric tumor perforation extending to the spleen, which presented as a perforated acute abdomen. The patient was treated with total gastrectomy and D2 lymph node resection with splenectomy and progressed well with current survival of one year at disease stage IV.


Resumo A neoplasia gástrica perfurada é uma condição incomum e de difícil diagnóstico pré-operatório, estando relacionada a estágios avançados e com alta mortalidade, principalmente na presença de choque pré-operatório. Poucos estudos foram feitos quanto a sua forma de apresentação e ao tratamento adequado. Além disso, não há nenhum relato em literatura quanto à extensão da perfuração para o baço, como é descrito neste caso, tornando mais difícil a conduta. Este artigo relata um caso de perfuração de neoplasia gástrica com extensão para o baço, que se apresentou como abdome agudo perfurativo. Submetido a gastrectomia total e ressecção linfonodal D2 com esplenectomia, apresentou boa evolução e sobrevida atual de 1 ano, em um estadiamento IV da doença.

ABSTRACT

La intususcepción en un adulto debe hacer sospechar un tumor (benigno o potencialmente riesgoso); el diagnóstico certero es crucial para el tratamiento adecuado del paciente1. Alrededor del 90% de estos casos se dan en el intestino delgado y colon, el 10% restante se originan en el estómago y en estomas creados quirúrgicamente2. En los adultos, aproximadamente 90% de los casos de intususcepción son secundarios a una lesión definible3. El tumor de Vanek o pólipo fibroide inflamatorio, se conoce como una lesión benigna, rara, de localización submucosa, no encapsulada, cuya ubicación puede darse a lo largo del tracto digestivo, siendo más común en el antro gástrico (80 %), aunque también se ha descrito en la unión gastroesofágica, duodeno, yeyuno, íleon y colon4.


Intussusception in an adult must make us suspect the presence of a tumor (benign or potentially dangerous) as the most frequent cause. Accurate diagnosis is of great importance in order to provide appropriate treatment and improve patient prognosis1. About 90% of these cases occur in the small intestine and colon, and the remaining 10% originate in the stomach and surgically created ostomas2. In adults, approximately 90% of cases of intussusception are secondary to a definable lesión3. The Vanek's tumor or inflammatory fibroid polyp (IFP) is a rare benign lesion of submucosal location, not encapsulated, that may be located throughout the digestive tract, being more common in the gastric antrum (80%), although it has also been described in the gastroesophageal junction, duodenum, jejunum, ileum and colon4.

ABSTRACT

La dermatomiositis es una enfermedad sistémica que se caracteriza fundamentalmente por la presencia de alteraciones inflamatorias de piel y músculo estriado. En ciertos casos constituye un síndrome paraneoplásico, por lo que su diagnóstico obliga a una exhaustiva búsqueda de la probable asociación con un cáncer. Presentamos tres casos de dermatomiositis asociados a neoplasias, dos mujeres con cáncer ginecológico y un varón con cáncer de estómago. Una de las mujeres también presentaba un síndrome mielodisplásico. En dos casos la dermatomiositis fue posterior al diagnóstico del cáncer y en uno los hallazgos fueron simultáneos.


Dermatomyositis is a systemic disease characterized primarily by the presence of inflammatory skin disorders and striated muscle. In some cases it constitutes a paraneoplastic syndrome, so diagnosis requires a thorough search of the likely association with cancer. We present three cases of dermatomyositis associated with malignancies, two women with gynecologic cancer and a man with stomach cancer. One of the women also had a myelodysplastic syndrome. In two cases dermatomyositis was after the diagnosis of cancer and in one, the findings were simultaneous.

ABSTRACT

BACKGROUND/AIMS: Helicobacter pylori cytotoxin-associated gene A (CagA) has been suggested to be involved in the inactivation of Runt-related transcription factor 3 (RUNX3), a known gastric carcinoma tumor suppressor gene. It remains unclear how H. pylori CagA initiates or maintains RUNX3 promoter methylation and inactivates its protein expression in gastric carcinoma. METHODS: RUNX3 promoter methylation status, RUNX3 expression, and H. pylori CagA were investigated in 76 sample pairs of gastric carcinoma tissue. The patients' medical records were reviewed. The association between RUNX3 methylation or loss of RUNX3 expression and clinicopathologic variables according to H. pylori CagA status were investigated. RESULTS: In gastric carcinoma patients with H. pylori CagA-positive infection, RUNX3 methylation did not show association with lymphatic invasion, venous invasion, and TNM stages. However RUNX3 methylation was observed more frequently in poorly differentiated adenocarcinoma and signet ring cell carcinoma (77.8% vs. 20.0%, p=0.023) in early stage. In gastric carcinoma patients with H. pylori CagA-positive infection, loss of RUNX3 expression did not show association with lymphatic invasion, venous invasion, and TNM stages. However loss of RUNX3 expression was observed more frequently in early gastric carcinoma than in advanced gastric carcinoma (84.2% vs. 75.0%, p=0.51), but this difference was not significant. CONCLUSIONS: In gastric carcinoma patients with H. pylori CagA-positive infection, RUNX3 methylation or loss of RUNX3 expression did not show correlation with lymphovascular invasion and TNM stages. In early gastric carcinoma patients with H. pylori CagA-positive infection, RUNX3 methylation was observed more in poorly differentiated adenocarcinoma and signet ring cell carcinoma.

ABSTRACT

Endoscopic submucosal dissection (ESD) has been successfully performed in thrombocytopenic conditions such as in patients with liver cirrhosis but successful ESD for early gastric cancer (EGC) in hematologic diseases has rarely been reported. A 52-year-old male patient, who had previously been diagnosed with myelodysplastic syndrome 2 years ago, was admitted to our hospital for ESD of EGC. ESD was performed successfully in this patient after platelet concentrates transfusion on the day of ESD. ESD might be an option for the treatment of EGC in thrombocytopenia due to hematologic diseases when optimal supportive managements are applied.

ABSTRACT

BACKGROUND/AIMS: This study was conducted to identify microRNAs (miRNAs) that are differentially expressed in Helicobacter pylori-infected patients with an intestinal type of gastric cancer using miRNA microarray and to confirm the candidate miRNA expression levels. METHODS: Total RNA was extracted from the cancerous and noncancerous regions of formalin-fixed, paraffin-embedded tissues of H. pylori-positive (n=8) or H. pylori-negative (n=8) patients with an intestinal type of gastric cancer. RNA expression was analyzed using a 3,523 miRNA profiling microarray based on the Sanger miRBase. Validation analysis was performed using TaqMan miRNA assays. RESULTS: A total of 219 miRNAs in the aberrant miRNA profiles across the miRNA microarray showed at least a 2-fold change differential expression in H. pylori-positive and H. pylori-negative cancer tissues. After candidate miRNAs were selected using online miRNA databases, TaqMan miRNA assays confirmed that three miRNAs (miR-99b-3p, miR-564, and miR-638) were significantly increased in three H. pylori-positive cancer tissues compared to the H. pylori-negative cancer tissues. Additionally, four miRNAs (miR-204-5p, miR-338-5p, miR-375, and miR-548c-3p) were significantly increased in H. pylori-negative cancer tissues compared to H. pylori-positive cancer tissues. CONCLUSIONS: miRNA expression in the intestinal type of H. pylori infection-dependent gastric cancer suggests that different gastric cancer pathogenesis mechanisms could exist between H. pylori-positive and H. pylori-negative gastric cancer.

ABSTRACT

BACKGROUND/AIMS: This study was conducted to identify microRNAs (miRNAs) that are differentially expressed in Helicobacter pylori-infected patients with an intestinal type of gastric cancer using miRNA microarray and to confirm the candidate miRNA expression levels. METHODS: Total RNA was extracted from the cancerous and noncancerous regions of formalin-fixed, paraffin-embedded tissues of H. pylori-positive (n=8) or H. pylori-negative (n=8) patients with an intestinal type of gastric cancer. RNA expression was analyzed using a 3,523 miRNA profiling microarray based on the Sanger miRBase. Validation analysis was performed using TaqMan miRNA assays. RESULTS: A total of 219 miRNAs in the aberrant miRNA profiles across the miRNA microarray showed at least a 2-fold change differential expression in H. pylori-positive and H. pylori-negative cancer tissues. After candidate miRNAs were selected using online miRNA databases, TaqMan miRNA assays confirmed that three miRNAs (miR-99b-3p, miR-564, and miR-638) were significantly increased in three H. pylori-positive cancer tissues compared to the H. pylori-negative cancer tissues. Additionally, four miRNAs (miR-204-5p, miR-338-5p, miR-375, and miR-548c-3p) were significantly increased in H. pylori-negative cancer tissues compared to H. pylori-positive cancer tissues. CONCLUSIONS: miRNA expression in the intestinal type of H. pylori infection-dependent gastric cancer suggests that different gastric cancer pathogenesis mechanisms could exist between H. pylori-positive and H. pylori-negative gastric cancer. Additional functional studies are required.
