Antral plexiform fibromyxoma: case report of a rare mesenchymal neoplasm

Plexiform fibromyxoma (PF) is a rare mesenchymal neoplasm of the stomach usually arising in the gastric antrum, and its main differential diagnosis is gastrointestinal stromal tumor. Most common symptoms are hematemesis, anemia. Immunohistochemically, positivity for smooth muscle actin (SMA) and vimentin suggests the diagnosis of PF. We report the case of a 56-year-old female patient with a 30- day history of nausea at presentation 4 years ago. Gastroscopy at that time revealed a subepithelial lesion (SEL) in the gastric antrum, measuring approximately 20 mm in diameter, with leakage of serous fluid after biopsy. Histopathology showed only an inflammatory process. Follow-up gastroscopies were performed 24, 36, and 48 months later, with surveillance biopsy at each follow-up. The last gastroscopies showed changes in lesion appearance, reduction in size, and absence of fluid leakage. Histopathology showed bland spindle cell proliferation, with a vaguely plexiform/multinodular pattern, in a fibromyxoid stroma with an arborizing capillary network without mitoses. The tumor cells were positive for SMA and negative for DOG1, CD117, CD34, S100, desmin, EMA, CD10, calponin, and beta-catenin. The choice of treatment and follow-up depends on the SEL features, but because no cases of malignancy or metastatic disease have previously been reported, the patient chose a conservative approach.

El fibromixoma plexiforme (FP) es una rara neoplasia mesenquimatosa del estómago que generalmente surge en el antro gástrico. Su principal diagnóstico diferencial es el tumor del estroma gastrointestinal. Los síntomas más comunes de los FP son hematemesis y anemia. Inmunohistoquímicamente, la positividad para actina del músculo liso (SMA) y vimentina sugieren el diagnóstico de FP. Presentamos el caso de una paciente de 56 años de edad que inicia su enfermedad hace 4 años con náuseas de 30 días de evolución. La primera gastroscopia reveló una lesión subepitelial (SEL) en el antro gástrico, de aproximadamente 20 mm de diámetro, con fuga de líquido seroso después de la biopsia. La histopatología mostró sólo un proceso inflamatorio. Se realizaron gastroscopias de seguimiento a los 24, 36 y 48 meses con biopsia de vigilancia en cada seguimiento. Las gastroscopias siguientes mostraron cambios en la apariencia de la lesión, reducción de tamaño y ausencia de fuga de líquido. La última histopatología mostró una proliferación blanda de células fusiformes, con un patrón vagamente plexiforme/multinodular, en un estroma fibromixoide con una red de capilares arborizantes sin mitosis. Las células tumorales fueron positivas para SMA y negativas para DOG1, CD117, CD34, S100, desmina, EMA, CD10, calponina y beta-catenina. La elección del tratamiento y el seguimiento depende de las características del SEL, sin embargo, por ser una enfermedad que no presentaba rasgos de enfermedad maligna o metastásica, el paciente eligió un mantener un enfoque conservador.

Clinical and Endoscopic Characterization of Gastrointestinal Kaposi's Sarcoma in an Institution in Southwestern Colombia between 2011 and 2020

Kaposi's sarcoma is an angioproliferative neoplasm associated with the human herpesvirus 8. According to the clinical characteristics and the degree of immunosuppression, there are four epidemiological forms: classic, endemic, iatrogenic, and epidemic. The latter is associated with acquired immunodeficiency syndrome (AIDS) and 40% GI involvement. There is little epidemiological, clinical, and endoscopic evidence of the disease. This study sought to characterize this condition in a Colombian population and compare the findings with publications from other countries. One hundred thirty-five records of patients who consulted between 2011 and 2020 for Kaposi's sarcoma were reviewed, of which 24 had GI involvement. Epidemiological, clinical, endoscopic, and treatment characteristics were obtained. Twenty-two patients were men. There were 21 patients infected with human immunodeficiency virus (HIV; 87.5%) and 19 receiving antiretroviral therapy (90%); 33.3% had HIV viral load > 100,000 copies/mL. The CD4+ count was <50 cells/µL in 28.6% of cases, between 50 and 100 cells/µL in 19.0%, and between 100 and 200 cells/µL in 14.4%. The rate of infection by other opportunistic infections was 41.7%. There were GI symptoms in 33% of the patients, and the most frequent were hematochezia, abdominal pain, nausea, and diarrhea. Most had concomitant skin lesions (70.8%). GI lesions were located mainly in the oropharynx (41.7%), stomach (20.8%), and colon (16.7%). The most common endoscopic finding was maculopapular erythema. This article provided insight into the local epidemiology of gastrointestinal Kaposi's sarcoma. In contrast to studies in other populations, GI symptoms were more frequent in this one, and there was a difference in endoscopic findings. Studies with larger populations are needed.

El sarcoma de Kaposi es una neoplasia angioproliferativa asociada al virus del herpes humano 8. Según las características clínicas y el grado de inmunosupresión, son cuatro las formas epidemiológicas: clásica, endémica, iatrogénica y epidémica, esta última asociada al síndrome de inmunodeficiencia adquirida (SIDA) y con un 40% de compromiso gastrointestinal. Existe escasa evidencia epidemiológica, clínica y endoscópica de la enfermedad. Este estudio buscó caracterizar esta condición en una población colombiana y contrastar los hallazgos con publicaciones de otros países. Se revisaron 135 registros de pacientes que consultaron entre el 2011 y 2020 por sarcoma de Kaposi, de los cuales 24 tenían compromiso gastrointestinal. Se obtuvieron características epidemiológicas, clínicas, endoscópicas y tratamientos. Veintidós pacientes eran hombres. Hubo 21 pacientes infectados por virus de la inmunodeficiencia humana (VIH; 87,5%) y 19 recibían terapia antirretroviral (90%). El 33,3% tenía carga viral VIH > 100 000 copias/mL. El recuento de CD4+ fue < 50 cel/µL en el 28,6% de los casos, entre 50 y 100 cel/µL en el 19,0%, y entre 100 y 200 cel/µL en el 14,4%. La tasa de infecciones por otros oportunistas fue de 41,7%. Hubo síntomas gastrointestinales en el 33% de los pacientes y los más frecuentes fueron hematoquecia, dolor abdominal, náuseas y diarrea. La mayoría tuvo lesiones cutáneas concomitantes (70,8%). Las lesiones gastrointestinales se localizaron principalmente en la orofaringe (41,7%), estómago (20,8%) y colon (16,7%). El hallazgo endoscópico más común fue eritema maculopapular. Este artículo mostró una visión de la epidemiología local del sarcoma de Kaposi gastrointestinal. En contraste con estudios en otras poblaciones, en este, los síntomas gastrointestinales fueron más frecuentes y hubo diferencia en los hallazgos endoscópicos. Son necesarios estudios con poblaciones más grandes.

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

Effect of individualized blood pressure management on postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor / 中华麻醉学杂志

Objective:To evaluate the effect of individualized blood pressure management on postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor.Methods:One hundred and sixty elderly hypertensive patients of both sexes, aged 60-80 yr, with body mass index of 19-28 kg/m 2, of American Society of Anesthesiologists Physical Status classification Ⅱ or Ⅲ, scheduled for elective radical resection for gastrointestinal tumor under general anesthesia, were divided into 2 groups ( n=80 each) using a random number table method: standardized blood pressure management group (group S) and individualized blood pressure management group (group I). Combined intravenous-inhalational anesthesia was performed, and BIS values were maintained at 40-60 and heart rate at 50-100 times/min during surgery in both groups. In group S, intraoperative systolic blood pressure was maintained above 90 mmHg with a decrease of less than 30% of the baseline value, while intraoperative fluctuation of systolic blood pressure was maintained less than 10% of the baseline value in group I. The use of vasoactive agents, numerical rating scale scores within 3 days after operation, and length of hospital stay were recorded. Postoperative delirium was evaluated by Confusion Assessment Method within 5 days after surgery. Results:Compared with group S, the intraoperative usage rate of norepinephrine was significantly increased, the incidence of postoperative delirium was reduced( P<0.05), and no significant change was found in the numerical rating scale scores and length of hospital stay in group I ( P>0.05). Conclusions:Individualized blood pressure management can reduce the development of postoperative delirium in elderly hypertensive patients undergoing radical resection for gastrointestinal tumor.

Association between the preoperative nocturnal blood pressure pattern and postoperative complications in elderly patients undergoing laparoscopic gastrointestinal surgery / 中华老年医学杂志

Objective:To explore the association between the preoperative nocturnal blood pressure pattern and postoperative complications in elderly patients undergoing laparoscopic gastrointestinal surgery.Methods:A prospective observational cohort study was conducted in 131 elderly patients undergoing elective laparoscopic gastrointestinal surgery under general anesthesia between September 2018 and September 2021.All subjects underwent 24 h ambulatory blood pressure monitoring 1 day before surgery and, based on the nocturnal blood pressure pattern, patients were divided into two groups.Those with the nocturnal blood pressure reduction rate ≥0% entered the nocturnal blood pressure reduction group(Group D, n=80), and those with the reduction rate <0% entered the nocturnal blood pressure increase group(Group R, n=51). Differences in postoperative complication rates between the two groups were compared, and multivariate Logistic regression was used to analyze the influencing factors of postoperative complications.Results:(1)Compared with Group D, the prevalence of diabetes and left ventricular mass index were significantly increased and the mean nighttime SBP and DBP were significantly increased in Group R( P<0.05); (2)Compared with Group D, the incidence of acute kidney injury and acute heart failure in Group R was significantly higher( P<0.05), with the relative risk( RR)values at 2.941(95% CI: 1.344-6.435)and 3.660(95% CI: 0.991-13.512), respectively; (3)Multivariate Logistic regression analysis showed that elevated blood pressure at night was an independent risk factor for acute kidney injury after surgery( OR=3.700, 95% CI: 1.286-10.648, P=0.015); (4)Kaplan-Meier curves for acute kidney injury and acute heart failure showed that the cumulative incidence of events in Group R was significantly higher than that in Group D(Log rank test: P<0.05). Conclusions:For elderly patients undergoing selective laparoscopic gastrointestinal surgery, preoperative nocturnal blood pressure patterns were associated with postoperative complications.Elevated preoperative nocturnal blood pressure increases the incidence of postoperative acute kidney injury and heart failure, and elevated nocturnal blood pressure is an independent risk factor for acute kidney injury.

Multiple linear regression analysis showed that the gender of caregiver, physical condition of caregivers, average monthly household income were significant influencing factors of family caregivers learned helplessness in patients with advanced digestive tract tumor ( P<0.05). Conclusions:The learned helplessness of family caregivers of patients with advanced digestive tract tumor is at a mild level. Nurses should focus on the physical and mental conditions of low-income groups and female caregivers with advanced digestive tract tumor, and regularly assess their nursing needs and health status to improve their quality of life.

LncRNA Prognostic Risk Scoring Model for Gastrointestinal Tumors Based on TCGA Database / 肿瘤防治研究

Objective To establish a lncRNA prognostic risk model for gastrointestinal tumors based on the TCGA database and evaluate the prognosis of patients. Methods We collected the data of patients with esophageal cancer, gastric cancer, colon cancer and rectal cancer in the TCGA database. Univariate Cox analysis, Lasso and multivariate Cox analysis were performed to construct the prognostic risk scoring model. The model was validated and tested for independence. Time-dependent ROC curve analysis was performed to evaluate the clinical application value of the model. Results We established a prognostic risk model based on 13 lncRNAs. The three-year AUC of the training set and the validation set were 0.746 and 0.704, respectively. The pan-cancer data set was divided into high- and low-risk groups for survival analysis. The 5-year survival rate of the low-risk group was significantly higher than that of the high-risk group; among all cancer types, the five-year survival rates of the low-risk group were higher than those of the high-risk group. Multivariate Cox analysis showed that the risk score could be an independent indicator of prognosis. Conclusion The 13-gene prognostic risk score model is constructed successfully. The risk score obtained by this model can be used as an independent prognostic predictor of the patients with gastrointestinal cancer.

Effect of electroacupuncture at different time points on the recovery of gastrointestinal function after surgery for gastrointestinal malignant neoplasms / 针灸推拿医学（英文版）

Objective: To observe the effect of electroacupuncture (EA) at different time points during the perioperative period on the recovery of gastrointestinal function after gastrointestinal malignant neoplasms surgery. Methods: Sixty-three patients who needed radical surgery for gastrointestinal tumors were randomized into a control group, treatment group 1 (postoperative EA group), and treatment group 2 (intraoperative and postoperative EA group). The control group received surgery and conventional Western medicine treatment, and treatment groups 1 and 2 received additional EA treatment at different time points. The initial flatus time after the surgery, visual analog scale (VAS) score at different time points after the surgery, the proportion of using patient-controlled analgesia (PCA) after the surgery, and the times of adding analgesics were observed in the three groups. Results: The initial flatus time after the surgery was earlier in treatment groups 1 and 2 than in the control group (P<0.05); the difference between treatment groups 1 and 2 was statistically insignificant (P>0.05). The VAS score was lower in treatment group 2 than in the control group at 6, 12, 24, and 72 h after the surgery (P<0.05); the VAS score was lower in treatment group 1 than in the control group only at 72 h after the surgery (P<0.05). There were no significant differences in the rate of using PCA among the three groups (P>0.05). Regarding the times of adding analgesics, it was less in treatment group 2 than in the control group at 12 h after the surgery (P<0.05). Conclusion: Either EA during and after the surgery or only after the surgery can hasten the initial flatus and boost the recovery of gastrointestinal function in patients after radical resection of gastrointestinal neoplasms. Successive EA during and after the surgery should be superior to postoperative EA regarding the analgesic effect after the surgery.

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.

At the end of Delphi II, the four protocols were significantly valid (lack of appetite [CVC = 0.98]; nausea and vomiting [CVC = 0.99]; diarrhea [CVC = 0.99]; and constipation [CVC = 0.98]). Conclusion The content of the protocols demonstrated high credibility and their adoption in health institutions can contribute to telephone follow-up in reducing side effects (lack of appetite, nausea and vomiting, diarrhea and constipation) associated with outpatient antineoplastic chemotherapy for people with gastrointestinal malignancies.

Increased postoperative fasting time aggravates the nutritional status in patients with gastrointestinal tract neoplasia

ABSTRACT Surgical patients with gastrointestinal cancer often suffer from malnutrition. This study aimed to evaluate the influence of fasting time on the nutritional status of patients hospitalized with preoperative and postoperative gastrointestinal tract neoplasms. Observational, longitudinal, and prospective study conducted in the surgical unit at a public-school hospital. The patients were divided into groups: upper (UGIT) and lower (LGIT) gastrointestinal tract. Follow-up started within 72 h of hospitalization with reassessment 72 h after surgery. Data collected: sex, age, type and duration of surgery, preoperative (compared with 8 h) and postoperative (compared with 24 h) fasting time, food acceptance, Subjective Global Assessment, anthropometry, and laboratory tests. Analyses: Student t, Wilcoxon, and chi-square tests. Fifty-one patients were followed up, 29 (57%) UGIT and 22 (43%) LGIT. The preoperative fasting time was 8.2±2.8 h in UGIT and 8.1±2.2 h in LGIT groups, respectively; however, postoperative fasting times in UGIT (60.4±40.7 h) and LGIT groups (57.6±38.2 h) were longer than 24 h (P<0.001). Although eutrophic in the preoperative period, in the postoperative most patients in the UGIT and LGIT groups presented, respectively, malnutrition (71%; 59%; P<0.001), severe weight loss (79%; 80%), a significant correlation between triceps skinfold and postoperative fasting time (r= -0.306; P= 0.03), and hemoglobin and albumin values (r= 0.633; P<0.001), additionally low dietary acceptance, especially in the UGIT group. Prolonging postoperative fasting time worsened the nutritional status of surgical patients, especially in the UGIT group.

RESUMEN Los pacientes quirúrgicos con cáncer gastrointestinal a menudo sufren desnutrición. El objetivo de este estudio fue evaluar la influencia del tiempo de ayuno en estado nutricional de pacientes hospitalizados con neoplasias del tracto gastrointestinal preoperatorio y posoperatorio. Estudio observacional, longitudinal y prospectivo realizado en unidad quirúrgica de un hospital escolar público. Los pacientes fueron divididos en grupos: tracto gastrointestinal superior (UGIT) y inferior (LGIT). El seguimiento se inició dentro del 72 h de la hospitalización con reevaluación 72 h después de la cirugía. Datos recolectados: sexo, edad, tipo y duración de la cirugía, tiempo de ayuno preoperatorio (comparado con 8 h) y postoperatorio (comparado con 24 h), aceptación de dieta, Evaluación Subjetiva Global, antropometría y pruebas de laboratorio. Análisis: pruebas de T, Wilcoxon y chi-cuadrado. Se siguió 51 pacientes, 29 (57%) en UGIT y 22 (43%) en LGIT. El tiempo de ayuno preoperatorio fue 8,2±2,8 h (UGIT) y 8,1±2,2 h (LGIT); sin embargo, los tiempos de ayuno posoperatorio en UGIT (60,4±40,7 h) y LGIT (57,6±38,2 h) fueron superiores a 24 h (P<0,001). Aunque eutróficos en preoperatorio, en postoperatorio la mayoría de los pacientes (UGIT y LGIT, respectivamente) presentaron desnutrición (71%; 59%; P<0,001), pérdida de peso severa (79%; 80%), correlación significativa entre pliegue cutáneo del tríceps y tiempo de ayuno posoperatorio (r= -0.306; P= 0.03), valores de hemoglobina y albúmina (r= 0,633; P<0,001), y baja aceptación de dieta, especialmente del UGIT. La prolongación del ayuno postoperatorio empeoró el estado nutricional de los pacientes quirúrgicos, especialmente del UGIT.

Disección endoscópica submucosa para el tratamiento de neoplasias incipientes del tubo digestivo: experiencia en un centro universitario de alto volumen / Experience with endoscopic submucosal dissection for the treatment of early neoplasms of the digestive tract

Background: Endoscopic submucosal dissection (ESD) allows en-bloc resection of early gastro-intestinal neoplasms (EGIN) with healing potential. Aim: To describe the results of patients treated with ESD for EGIN by our team. Patients and Methods: Descriptive study of patients with EGIN who underwent ESD with curative intention between January 2008 and March 2020. Results: One hundred thirty-two ESD were performed in 127 patients. 77% were gastric lesions, 14% colorectal, 8% esophageal and 1% duodenal. En-bloc resection was achieved in 98.4% of ESDs. Eighty eight percent of patients met curative standards. Overall, cancer-specific, and recurrence-free survival were 95%, 100% and 98% respectively. Conclusions: ESD allows en-bloc resections with curative potential in selected patients, but with a significant reduction in morbidity and mortality and less impact on quality of life. Our results suggest the feasibility to perform ESD in our country with results comparable to those reported in the literature.
