Introducción. El tumor miofibroblástico inflamatorio es una enfermedad proliferativa rara, de etiología incierta, caracterizada por la proliferación de miofibroblastos epitelioides o fusionados mezclados con células inflamatorias, predominantemente mononucleares. En general se considera una lesión benigna, aunque en algunos casos esta neoplasia ha mostrado un comportamiento agresivo en cuanto a recidiva local y metástasis. El tratamiento definitivo es la resección quirúrgica completa. Caso clínico. Paciente de 67 años con dos meses de evolución de fiebre y masa abdominal, en quien se realizó una tomografía computarizada de abdomen que identificó una lesión de aspecto infiltrativo tumoral, comprometiendo la grasa retroperitoneal en la transcavidad de los epiplones. Por vía percutánea se tomó una biopsia que informó un pseudotumor inflamatorio retroperitoneal. Fue llevado a cirugía radical abdominal, con patología quirúrgica final que describió un tumor miofibroblástico inflamatorio de compromiso multifocal, adherido a la serosa del estómago e intestino delgado, sin compromiso muscular. Discusión. El tumor inflamatorio miofibroblástico es una entidad rara, de etiología por esclarecer y difícil diagnóstico. Presentamos el caso clínico de un paciente con tumor inflamatorio miofibroblástico gastrointestinal.Conclusión. Se describe el caso clínico de un paciente con un tumor inflamatorio miofibroblástico gastrointestinal, de presentación rara en nuestro medio. Es importante la comparación con casos similares para poder hacer conclusiones útiles en la práctica clínica

Introduction. Inflammatory myofibroblastic tumor is a rare proliferative disease of uncertain etiology, characterized by the proliferation of epithelioid or fused myofibroblasts mixed with predominantly mononuclear inflammatory cells. In general, it is considered a benign lesion, although in some cases this neoplasm has shown aggressive behavior in terms of local recurrence and metastasis. The definitive treatment is complete surgical resection. Clinical case. A 67-year-old patient with a two-month history of fever and an abdominal mass underwent a computed tomography scan of the abdomen that identified an infiltrative tumor, compromising the retroperitoneum fat in the lesser cavity. A biopsy was taken percutaneously, which reported a retroperitoneal inflammatory pseudotumor. He was taken to radical abdominal surgery, with final surgical pathology describing an inflammatory myofibroblastic tumor with multifocal involvement attached to the serosa of the stomach and small intestine without muscle involvement. Discussion. Inflammatory myofibroblastic tumor is a rare entity, of unknown etiology and difficult to diagnose. We present a clinical case of gastrointestinal myofibroblastic inflammatory tumor to better understand this entity.Conclusion. The clinical case of a patient with a gastrointestinal myofibroblastic inflammatory tumor, a rare presentation in our environment, is described. Comparison with similar cases is important to draw useful conclusions in clinical practice

Angiosarcoma gastrointestinal multifocal, con compromiso extenso de estómago, intestino delgado y colon. Reporte de un caso / Multifocal gastrointestinal angiosarcoma, with extensive gastric, small intestine and colon involvement. A case report

Introducción. El angiosarcoma es una neoplasia vascular originada a nivel del endotelio, de baja frecuencia, conocido por su agresividad y crecimiento acelerado. Alcanza solo el 1 al 2 % del total de los sarcomas. La presentación gastrointestinal es infrecuente y su incidencia es poco conocida debido al escaso reporte de casos en la literatura. Suele identificarse en etapas avanzadas debido a la dificultad del diagnóstico histopatológico por sus características morfológicas, siendo necesario aplicar tinciones especiales o estudio inmunohistoquímico. Caso clínico. Por su interés y singularidad, presentamos el caso de un paciente masculino de 54 años, quien consultó con hemorragia digestiva profusa, anemización y requerimiento de terapia transfusional. Resultados. Durante el proceso diagnóstico, en la endoscopia encontraron diversas lesiones multifocales que se extendían por gran parte del tracto gastrointestinal. El estudio histopatológico mostró angiosarcoma gastrointestinal. Discusión. El angiosarcoma del tracto gastrointestinal es extremadamente infrecuente, de difícil diagnóstico y bajas posibilidades de manejo curativo, con opciones terapéuticas limitadas, lo que configura un mal pronóstico a corto plazo

Introduction. Angiosarcoma is a vascular neoplasm originating from endothelial cells, known for its aggressiveness, accelerated growth and reduced frequency. Reach only 1 to 2% of total sarcomas. Gastrointestinal presentation is extremely rare, the true incidence is poorly known, due to the limited reports of this entity in the literature. It is usually identified in advanced stages in view of the difficulty of the histopathological diagnosis, attributable to its morphological characteristics, being necessary to apply special stains or immunohistochemical study. Case report. Due to their interest and uniqueness, we present the case of a 54-year-old male patient, who presented with a profuse gastrointestinal bleeding, anemia, and requirement for transfusion therapy. Results. The endoscopy detected several multifocal lesions that extended most of the gastrointestinal tract. The histopathological study showed gastrointestinal angiosarcoma. Discussion. Angiosarcoma of the gastrointestinal tract is extremely uncommon, difficult to diagnose and has low possibilities of curative management, with limited therapeutic options, which configures a poor prognosis in the short term

Tumor de GIST, presentación no habitual / GIST tumor: an unusual presentation

RESUMEN El tumor estromal gastrointestinal representa el 3% de las neoplasias gastrointestinales; es el tumor mesenquimático más frecuente. Afecta a hombres mayores de 50 años. El 80% son benignos, la mayoría afectan el estómago e intestino delgado. La incidencia de localización extragastrointestinal es desconocida. Paciente masculino de 56 años, tabaquista, obeso, con hipertensión arterial (HTA) y diabético (DBT), anticoagulado, consulta por dolor en fosa ilíaca derecha, posterior a esfuerzo físico. Se realiza tomografía computarizada (TC) donde se visualiza lesión de aspecto expansivo intraperitoneal que muestra realce periférico. Se decide conducta quirúrgica. Se halla un tumor mesentérico. En su presentación, estos tumores hasta en un 60% suelen ser asintomáticos por lo que resultan solo un hallazgo imagenológico; es indispensable, pues, su sospecha clínica y fundamentalmente el aporte de la inmunohistoquímica para la definición de la patología. El CD 117 es el principal marcador. Su tratamiento de preferencia es siempre quirúrgico, acompañado de tratamientos quimioterápicos.

ABSTRACT Gastrointestinal stromal tumors (GISTs) account for < 3% of gastrointestinal neoplasms and are the most common mesenchymal tumors. They are more common in men > 50 years. They are benign in 80% of the cases and usually occur in the stomach and small intestine. The incidence of extragastrointestinal GISTs is unknown. A 56-year-old male patient sought medical care for abdominal pain in the right iliac fossa that appeared after exercising. The patient was a current smoker, obese, had a history of hypertension (HTN) and diabetes (DBT) and was receiving anticoagulants. A computed tomography (CT) scan showed an expansive mass within the peritoneum with peripheral enhancement. Surgical management was decided. During the procedure, a tumor was found in the mesentery. Up to 60% of these tumors are usually asymptomatic and are incidentally found in imaging tests; therefore, clinical suspicion and, most importantly immunohistochemistry, are essential for the diagnosis. CD117 is the main marker. Surgery is the treatment of choice for GISTs and chemotherapy is also indicated.

Introducción. A nivel mundial los tumores gastrointestinales tienen un impacto importante en la mortalidad y se asocian a diferentes factores, entre ellos regionales y sociodemográficos. El objetivo de este estudio fue describir la variación en el tiempo del cáncer gastrointestinal en una población del centro occidente de Colombia, dada su alta incidencia y desenlace frecuentemente fatal.Métodos. Se realizó un estudio retrospectivo observacional con muestreo no probabilístico en un tiempo de seis años. Se seleccionaron pacientes diagnosticados con algún tipo de neoplasia del tracto digestivo, en un hospital de tercer nivel del centro occidente de Colombia. Resultados. Se evaluaron un total de 1152 pacientes. Los tumores del tracto digestivo superior (esófago, unión esófago-gástrica y estómago) fueron los más frecuentes (44 %), seguidos de los tumores del tracto digestivo medio e inferior (intestino delgado, colon, recto y ano; 31 %) y de los tumores hepato-bilio-pancreáticos (25 %). La edad media de presentación fue 64,6 años, con una mayor frecuencia en el sexo masculino (51,6 %). El adenocarcinoma fue el tipo histológico más común.Conclusión. Los resultados de este estudio muestran que los tumores gastrointestinales son una neoplasia frecuente en nuestro país, siendo los tumores gástricos los que se presentan con mayor prevalencia, seguidos de los tumores colorrectales y las neoplasias biliopancreáticas, las cuales se mantiene en el tiempo.

Introduction. Worldwide, gastrointestinal tumors have a significant impact on mortality and are associated with different factors, including regional and sociodemographics. The objective of this study was to describe the variation over time of gastrointestinal cancer in a population from Central-Western Colombia, given its high incidence and frequently fatal outcome. Methods. An observational retrospective study with non-probabilistic sampling was carried out over a period of six years. Patients diagnosed with some type of neoplasm of the digestive tract were selected in a tertiary care hospital in the Central-Western Colombia. Results. A total of 1152 patients were evaluated. Tumors of the upper digestive tract (esophagus, esophagogastric junction, and stomach) were the most frequent (44%), followed by tumors of the middle and lower digestive tract (small intestine, colon, rectum and anus; 31%), and hepatobiliary-pancreatic tumors (25%). The mean age of presentation was 64.6 years with a higher frequency in males (51.6%). Adenocarcinoma was the most common histological type.Conclusion. The results of this study show that gastrointestinal tumors are a frequent neoplasm in our country, with gastric tumors being the most prevalent, followed by colorectal tumors and biliopancreatic neoplasms, which are maintained over time.

Condroma pulmonar y paraganglioma carotídeo como manifestaciones de la tríada de Carney: reporte de un caso / Pulmonary chondroma and carotid paraganglioma as expressions of Carney's triad: report of a case

Resumen Objetivos: Presentar caso clínico y revisión de la literatura sobre asociación de tumores poco frecuentes compatibles con diagnóstico de tríada de Carney. Paciente y Métodos: Revisión de ficha clínica de paciente de sexo femenino de 39 años de edad con antecedentes de asma, quien acude a servicio de urgencias por síntomas respiratorios. En estudio con imágenes se evidencia masa pulmonar en lóbulo superior derecho probablemente hamartoma y masa en la bifurcación carotídea izquierda compatible con posible paraganglioma. Se completó el estudio con endoscopia digestiva alta sin evidencia de tumor gástrico y PET-CT (tomografía de emisión de positrones-tomografía computarizada) que descartó otras lesiones. Resultados: La paciente fue sometida a resección quirúrgica de ambos tumores (pulmonar y carotídeo). En estudio histopatológico diferido, se plantean los diagnósticos de paraganglioma carotideo y hamartoma pulmonar, el cual, luego de una segunda revisión histopatológica, es corregido a condroma pulmonar. Discusión: La tríada de Carney se compone por la asociación de al menos 2 de 3 tumores: tumor estromal gastrointestinal (GIST), paraganglioma extra-adrenal y condroma pulmonar. Su expresión es variable, coexistiendo en forma completa en solo el 22% de los casos. Conclusión: Los pacientes con sospecha de tríada de Carney deben recibir evaluación multidisciplinaria, estudio completo en búsqueda de tumores asociados y seguimiento a largo plazo por posibles recurrencias o metástasis.

Objective: To present a clinical case and review of the literature on the infrequent association of pulmonary and extra thoracic tumors compatible with Carney's triad. Patient and Methods: Review of clinical records of a 39 years-old female patient with history of asthma who presented in the emergency department with respiratory symptoms. An imaging study showed a pulmonary mass in the right upper lobe with the aspect of hamartoma and a mass in the left carotid artery bifurcation compatible with a possible paraganglioma. Upper gastrointestinal endoscopy showed no evidence of gastric tumor and a PET-CT (Positron Emission Tomography - Computed Tomography) excluded other lesions. Results: Patient underwent surgical resection of both tumors (pulmonary and carotid). Diagnosis of carotid paraganglioma and pulmonary hamartoma were stated by histopathology. However, lung tumor after a second pathological analysis was confirmed to be a pulmonary chondroma. Discussion: Carney's triad is defined by the association of at least 2 of 3 tumors: Gastrointestinal Stromal Tumor (GIST), extraadrenal paraganglioma and pulmonary chondroma. Its expression is variable, coexisting completely in only 22% of cases. Conclusion: Patients with suspected Carney's triad should receive a multidisciplinary assessment, a complete study searching associated tumors and long-term follow-up for recurrences or metastases.

Prognostic factors and management of colorectal gastrointestinal stromal tumors

Introduction: The gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract. Even though it can be found in any location of the digestive tract, the colorectal GIST is rare. With this study, we aim to review the current knowledge regarding the prognosis and management of colorectal GIST. Methods: A literature search was conducted in PubMed, and 717 articles were collected. After analyzing these studies, 60 articles were selected to use in this review. Results: The mitotic index, as well as tumor size and location were identified as good discriminators of prognosis in various studies. Surgery remains the only curative therapy for potentially resectable tumors. However, even after surgical resection, some patients develop disease recurrence and metastasis, especially those with highrisk tumors. Therefore, surgical resection alone might be inadequate for the management of all colorectal GISTs. The discovery of GIST's molecular pathway led to a shift in its therapy, insofar as tyrosine kinase inhibitors became part of the treatment schemes for this tumor, revolutionizing the treatment's outcome and prognosis. Discussion/Conclusion: The controversy concerning colorectal GIST prognosis and treatment can be, in part, attributed to the limited number of studies in the literature. In this review, we gathered the most recent knowledge about the prognosis and management of GIST in this rare location and propose two algorithms for its approach. Lastly, we highlight the importance of an individualized approach in the setting of a multidisciplinary team. (AU)

Postoperative ileus after laparotomy for gastrointestinal cancer treated with electroacupuncture: a randomized controlled trial / 中国针灸

OBJECTIVE@#To observe the effect of electroacupuncture (EA) on postoperative ileus after laparotomy for gastrointestinal cancer.@*METHODS@#A total of 90 patients with postoperative ileus after laparotomy for gastrointestinal cancer were randomized into an EA group and a conventional treatment group, 45 cases in each one. In the conventional treatment group, the postoperative fast track surgical regimen was accepted. In the EA group, on the base of the treatment as the conventional treatment group, acupuncture was applied to Zusanli (ST 36), Shangjuxu (ST 37), Yinlingquan (SP 9) and Taichong (LR 3) and electric stimulation was attached on Zusanli (ST 36) and Yinlingquan (SP 9), with continuous wave, 2 Hz in frequency and 3-5 mA in intensity. Acupuncture was provided once daily till the onset of postoperative exhaust and defecation. The first postoperative exhaust time, the first postoperative defecation time, the postoperative hospital stay and the wound pain under standing on the next morning after entering group were compared in the patients between the two groups. The impact of the EA expectation was analyzed on the first postoperative exhaust time, the first postoperative defecation time and the postoperative hospital stay separately.@*RESULTS@#The first postoperative exhaust time and the first postoperative defecation time in the EA group were earlier than the conventional treatment group (P<0.05), the postoperative hospital stay was shorter than the conventional treatment group (P<0.05), and the rate of wound pain in the postoperative standing was lower than the conventional treatment group (P<0.05). EA expectation had no obvious correlation with the clinical therapeutic effect (P>0.05).@*CONCLUSION@#EA can relieve postoperative ileus symptoms, alleviate pain and shorten hospital stay in the patients after laparotomy for gastrointestinal cancer.

Thinking and suggestions on pathway management of perioperative enhanced recovery after surgery in gastrointestinal tumors in China / 中华胃肠外科杂志

Enhanced recovery after surgery (ERAS) is a multimodal perioperative care program to decrease the risk of delayed hospitalization, medical complications, readmission and to improve patient short- and long-term outcomes with minimized level of surgical stress responses through multidisciplinary cooperation. Despite its huge success, the program has challenges for further optimization with a primary focus on modification according to the specific pathophysiology and perioperative management characteristics of patients with gastrointestinal tumors to improve the compliance and implementation rate of items. Patient education, prehabilitation, multimodal analgesia, precision surgery, early mobilization, early oral feeding and oral nutrition supplement (ONS) should be regarded as core terms suitable for all the patients. During the application of ERAS pathway management, it is necessary to fully understand the perioperative changes of organ function and pathophysiology, and to strictly implement the ERAS program and items based on evidence-based medicine. Moreover, the close collaboration of multidisciplinary teams is needed to improve the compliance and increase the adherence rate of ERAS protocol for patients, which emphasizes the dynamic, gap-free and whole course management that covers pre-hospital, pre-operative, intra-operative, post-operative and post-hospital periods. Concurrently, we encourage our patients and their families to participate in the whole healthcare activities. Even more concerning, it is indispensable to adjust ERAS program for special time and special patients. At present, several consensus and guidelines on the ERAS management of gastrointestinal tumor surgery have come out for clinical practice in China, which, however, still lacks a high-level evidence from more high-quality clinical trials conducted by Chinese researchers. It is urgent to carry out a series of large-scale randomized controlled studies in accordance with international standards to obtain high-level evidence-based medical evidence for clinical practice, which is problem-oriented and integrated with features of metabolism and perioperative management of gastrointestinal tumor surgery.

There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ2 test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

Progress on clinical trials of common gastrointestinal cancer drugs in China from 2012 to 2021 / 中华肿瘤杂志

Objective: Systematically summarize the research progress of clinical trials of gastric cancer oncology drugs and the overview of marketed drugs in China from 2012 to 2021, providing data and decision-making evidence for relevant departments. Methods: Based on the registration database of the drug clinical trial registration and information disclosure platform of Food and Drug Administration of China and the data query system of domestic and imported drugs, the information on gastric cancer drug clinical trials, investigational drugs and marketed drugs from January 1, 2012 to December 31, 2021 was analyzed, and the differences between Chinese and foreign enterprises in terms of trial scope, trial phase, treatment lines and drug type, effect and mechanism studies were compared. Results: A total of 114 drug clinical trials related to gastric tumor were registered in China from 2012 to 2021, accounting for 3.7% (114/3 041) of all anticancer drug clinical trials in the same period, the registration number showed a significant growth rate after 2016 and reached its peak with 32 trials in 2020. Among them, 85 (74.6%, 85/114) trials were initiated by Chinese pharmaceutical enterprise. Compared with foreign pharmaceutical enterprise, Chinese pharmaceutical enterprise had higher rates of phase I trials (35.3% vs 6.9%, P=0.001), but the rate of international multicenter trials (11.9% vs 67.9%, P<0.001) was relatively low. There were 76 different drugs involved in relevant clinical trials, of which 65 (85.5%) were targeted drugs. For targeted drugs, HER2 is the most common one (14 types), followed by PD-1 and multi-target VEGER. In the past ten years, 3 of 4 marketed drugs for gastric cancer treatment were domestic and included in the national medical insurance directory. Conclusions: From 2012 to 2021, China has made some progress in drug research and development for gastric carcinoma. However, compared with the serious disease burden, it is still insufficient. Targeted strengthening of research and development of investment in many aspects of gastric cancer drugs, such as new target discovery, matured target excavating, combination drug development and early line therapy promotion, is the key work in the future, especially for domestic companies.

Research Advances in the Role of Keratins in Gastrointestinal Cancer / 中国医学科学杂志(英文版)

The incidence and mortality rates of gastrointestinal (GI) cancer remain high. Despite constant improvements in diagnostic and therapeutic techniques, the early diagnosis, mid- and late-stage treatment, drug tolerance, and cancer recurrence and metastasis in GI cancer remain challenging. In this review article we summarize the recent research advance in the roles of keratins in GI cancer, with the hope that they will become efficient biomarkers for the prediction, diagnosis, or treatment of these malignancies.

A comparative analysis of the distribution of the high-risk population of upper gastrointestinal cancer and endoscopic screening compliance in two urban areas and two rural areas in China / 中华肿瘤杂志

Objective: To analyze and compare the distribution of the high-risk population of upper gastrointestinal (UGI) cancer and the factors influencing the compliance rate of endoscopic screening in urban China and rural China. Methods: From 2015 to 2017, an epidemiological survey was conducted on residents aged 40-69 in two rural areas (Luoshan county of Henan province, Sheyang county of Jiangsu province) and two urban areas (Changsha city of Hunan province, Harbin city of Heilongjiang province). As a result, high-risk individuals were recommended for endoscopic screening. Chi-square χ(2) test was used to compare the high-risk rate of UGI cancer between urban and rural residents. In addition, the multivariate logistic regression model was used to analyze the factors influencing the compliance rate of endoscopic screening. Results: A total of 48, 310 residents aged 40-69 were enrolled in this study, including 22 870 (47.34%) residents from rural areas and 25 440 (52.66%) residents from urban areas. A total of 23 532 individuals were assessed with a high risk of UGI cancer, with an overall risk rate of 48.71%. A higher proportion of participants with high risk was observed in rural China (56.17%, 12 845/22 870) than in urban China (42.01%, 10 687/25 440). A total of 10 971 high-risk individuals with UGI cancer participated in endoscopic screening, with an overall compliance rate of 46.62% (10 971/23 532), 45.15% (5 799/12 845) in rural China, and 48.40% (5 172/10 687) in urban China. In rural population, the compliance rate of endoscopic screening was higher in those of females, aged 50-69 years, primary school education or above, high income, a family history of UGI cancer, history of gastric and duodenal ulcer, history of reflux esophagitis, and history of superficial gastritis, but lower in smokers (P<0.05). Among the urban population, the compliance rate of endoscopic screening was higher in those aged 40-49 years, uneducated, low income, family history of UGI cancer, history of reflux esophagitis, history of superficial gastritis, but lower in smokers (P<0.05). Conclusions: The proportion of participants with high risk of UGI cancer in rural areas is higher than that of urban areas. The compliance rates of endoscopic screening in urban and rural areas are low, and influencing factors of endoscopic screening exhibit some differences in rural China and urban China.

Tumores estromales gastrointestinales (GIST) gástricos, serie de casos / Gastrointestinal stromal tumors (GIST). Case series

Resumen Introducción: Los tumores estromales gastrointestinales (GIST) representan hasta el 2 % de las neoplasias gastrointestinales, estos aparecen en cualquier parte del tracto gastrointestinal y son encontrados más frecuentemente en el estómago (60 %). El diagnóstico se realiza por la expresión de un receptor de factor de crecimiento de tirosina-cinasa, antígeno de diferenciación (CD) 117, lo que lo diferencia de los otros tumores mesenquimales como leiomiomas, leiomiosarcomas, leiomioblastomas y tumores neurogénicos, que no expresan esta proteína. Objetivo: El objetivo de nuestro trabajo es caracterizar los GIST de localización gástrica con respecto a su presentación clínica, diagnóstico, manejo, recurrencia y supervivencia. Métodos: Se trata de un estudio observacional, retrospectivo basado en una serie de casos. Se realizó una extracción de la información por medio de la revisión de las historias clínicas de los pacientes con GIST gástricos en un centro oncológico de Bogotá entre enero de 2005 y diciembre de 2015. La información recolectada incluyó tipo de manejo y abordaje quirúrgico, localización, tamaño, índice mitótico y clasificación de riesgo. Resultados: Se encontraron 31 pacientes con diagnóstico de GIST gástrico. La edad media fue de 62,3 años, con una mediana de 61 años. De los 31 pacientes, 18 fueron mujeres y 13 hombres. El tiempo de seguimiento estuvo entre un mínimo de 2,4 meses y un máximo de 214 meses, La mediana de seguimiento fue de 36 meses. Conclusiones: Los GIST son tumores potencialmente malignos, y el de localización gástrica es el más frecuente. El diagnóstico y tratamiento dependen de su tamaño y localización dentro del estómago. El manejo es variado y consiste en la resección quirúrgica, en la que los procedimientos son mínimamente invasivos, en combinación con la endoscopia, que son una buena alternativa al tratamiento abierto hasta que haya necesidad de terapia sistémica.

Abstract Introduction: Gastrointestinal stromal tumors (GIST) account for up to 2% of gastrointestinal neoplasms. They may appear anywhere in the gastrointestinal tract and are most frequently found in the stomach (60%). The diagnosis is made based on the expression of the tyrosine-protein kinase KIT CD117, which differentiates it from other mesenchymal tumors such as leiomyomas, leiomyosarcomas, leiomyoblastomas, and neurogenic tumors, that do not express this protein. Objective: To characterize the clinical presentation, diagnosis, treatment, recurrence, and survival of GISTs in the stomach. Materials and methods: This is an observational retrospective study based on a case series. Data was collected after reviewing the medical records of patients diagnosed with GIST at a cancer center in Bogotá between January 2005 and December 2015. The data included type of treatment and surgical approach, location, size, mitotic index, and risk classification. Results: There were 31 patients diagnosed with GIST. Their mean age was 62.3 years, with a median of 61 years. Of the 31 patients, 18 were women and 13 were men. Follow-up time ranged from a minimum of 2.4 months to a maximum of 214 months. The median follow-up time was 36 months. Conclusions: GISTs are potentially malignant tumors, with gastric location being the most frequent. Diagnosis and treatment depend on their size and location in the stomach. Treatment options vary, ranging from surgical resection, where minimally invasive procedures along with endoscopy are a suitable alternative to open surgery, to the need for systemic therapy.

GIST duodenal asociado a hemorragia digestiva alta: reporte de caso / Duodenal GIST associated with upper gastrointestinal bleeding: case report

Resumen Introducción Los tumores del estroma gastrointestinal (GIST) corresponden al 1% de todas las neoplasias gastrointestinales, sin embargo, sólo el 3-5% de estos se desarrollan en el duodeno. Objetivo Reportar el caso de un paciente masculino con localización atípica de un tumor de estroma gastrointestinal y su manejo. Caso clínico paciente masculino de 50 años con antecedente de traumatismo encefalo craneano (TEC) con daño orgánico cerebral secundario, tabaquismo, consumidor de alcohol ocasional y sometido a quistectomía branquial en la infancia, que consulta en el servicio de urgencias por cuadro de hemorragia digestiva alta con compromiso hemodinámico. Tras realizar endoscopia digestiva alta (EDA), resonancia nuclear magnética (RNM) y tomografía computada (TC) de abdomen, se pesquisa masa tumoral en segunda porción de duodenal. Discusión A pesar de que la presentación clínica de los GIST es variable, lo más frecuente es que sean pacientes asintomáticos. En algunas ocasiones, al igual que en este reporte, pueden presentarse con dolor abdominal y/o hemorragia digestiva alta. El diagnóstico preoperatorio fue difícil ya que el estudio con imágenes (TC, RNM, EDA) sólo permite establecer la sospecha; el diagnóstico definitivo se realizó con biopsia (no contamos con endosonografía en nuestro centro). Debido a los sitios de reparo anatómico, no existe una cirugía estandarizada; en este caso, debido a la localización, infiltración y características, se decidió realizar una pancreatoduodenectomía.

Introduction Gastrointestinal stromal tumors (GIST), corresponds to 1%, of all gastrointestinal neoplasms, however, only 3%-5% developed in duodenum. Aim To report a case of a male patient with atypical location of gastrointestinal stroma tumor and the treatment proposed. Case report 50-year-old male patient, with medical history of organic brain damage secondary a traumatic brain injury, smoker, occasional alcohol consumer and branquial cystomy during childhood. Consulted in the emergency department for a high digestive hemorrhage case with hemodynamic compromise. Upper digestive endoscopy, computed tomography and nuclear magnetic resonance were performed, which impresses tumor-like lesion in the second duodenal portion. Discussion Although the GIST clinical presentation is variable, most often they are asymptomatic patients. In some times, as in this report, they may present with abdominal pain and/or upper gastrointestinal bleeding. The preoperative diagnosis was difficult, because the imaging study (CT, RNM, EDA) only stablished the suspicion and the final diagnosis was made by biopsy (we don't have endosonography in our center). Due to the anatomic repair, there is not a standardized surgery, in this case, due tumor location, infiltration and characteristics, it was decided to perform a pancreatoduodenectomy.
