“…

ReviewESD is currently the first-line of treatment in the eradication of the pre-malignant and early malignant neoplasms, demonstrating in most studies, mainly from Asia, high rates of efficiency and safety in expert hands. This also reinforces the concept of early detection of pre-malignant and malignant lesions using virtual chromoendoscopy/endoscopic magnification techniques associated with a systematic and sequential revision, based on an endoluminal endoscopic anatomy [1][2][3].

“…To solve the quality problem of the original image, computer-aided diagnosis technology has been widely introduced. e computer processing technology is used to analyze and calculate medical images and assist radiologists to find lesions, thus improving the accuracy of diagnosis [11][12][13]. Medical image intelligent segmentation is an important research field in modern medical image processing, and it is also the basis of follow-up medical operations such as lesion extraction, detection, and tracking.…”

To analyze the evaluation of artificial intelligence algorithm combined with gastric computed tomography (CT) image in clinical chemotherapy for advanced gastric cancer, 112 patients with advanced gastric cancer were selected as the research object. Among which, 56 patients in the experimental group received paclitaxel (PTX) combined with decitabine sequential decitabine maintenance therapy. Fifty-six patients in the control group received first-line treatment with decitabine combined with cisplatin. The image segmentation algorithm based on fast interactive dictionary selection was used to process gastric CT images. Complete response (CR), partial response (PR), stable disease (SD), progressive disease (PD), response rate (RR), disease control rate (DCR), and overall survival (OS) after treatment were recorded. The true-positive rate (TPR) and coincidence ratio (CR) of the proposed algorithm for image segmentation were significantly higher than those of the mean shift algorithm and the iCoseg algorithm. The mean edge distance (MED) and edge distance variance (EDV) were significantly lower than the mean shift algorithm and the iCoseg algorithm, and the differences were considerable ( P < 0.05 ). The number of CR (5 cases), PR (13 cases), RR (18 cases), and DCR (44 cases) in the experimental group was significantly higher than that in the control group, while the number of PD (12 cases) was significantly lower than that in the control group ( P < 0.05 ). The number of patients complicated with hematological toxicity, leucopenia, thrombocytopenia, and digestive tract reaction in the experimental group was less than that in the control group ( P < 0.05 ). From the comparison of long-term efficacy, the survival rate of patients in both groups showed a decreasing trend within 24 months, but the decreasing trend of survival rate of patients in the experimental group was better than that in the control group. In short, the proposed algorithm had better segmentation performance than traditional algorithms. Compared with first-line treatment with decitabine and cisplatin, PTX in combination with decitabine sequential citabine maintenance regimens had better disease control rates, lower toxicity, and more effective improvements in patient quality of life and longer survival in patients with advanced gastric cancer.

“…El factor de riesgo más importante para adenocarcinoma de tipo intestinal es H. pylori, por lo que la disminución de esta infección, favorecería también la disminución en la incidencia del cáncer gástrico de tipo intestinal (Icaza-Chávez et al, 2020), entre otros factores de riesgo adicionales tenemos edad, sexo, factores dietéticos, tabaquismo, droga, ubicación geográfica, nivel socioeconómico y genética, algunos de ellos aún se encuentran en discusión (Lyons et al, 2019) (Eusebi et al, 2020).…”

Desde su descubrimiento Helicobacter pylori (H. Pylori) ha sido ampliamente estudiado y se ha encontrado asociado a niveles socioeconómicos bajos donde la prevalencia es mayor. Este microorganismo está involucrado en un amplio espectro de patología gástrica como: gastritis crónica, úlceras pépticas, adenocarcinoma y linfoma. En la actualidad se acepta el rol etiológico importante de H. pylori en el cáncer gástrico y sus lesiones precursoras, por lo que consideramos importante actualizar información sobre esta temática. Objetivo: Determinar el rol del Helicobacter pylori en el cáncer gástrico y sus lesiones precursoras, a través de la búsqueda bibliográfica en revistas científicas de los últimos 5 años. Métodos: Es un estudio descriptivo, retrospectivo, basado en la obtención de información documental sistemática de investigaciones realizadas en diferentes partes del mundo. Se recurrió a las siguientes bases de datos ScIELO, Science Direct y Google Académico, se seleccionaron artículos en inglés y en español. Resultados: Se seleccionaron 25 estudios publicados entre el 2015 y 2020 con los cuales se pudo dar cumplimiento al objetivo planteado. Conclusiones: H. pylori se encuentra involucrado en la génesis del cáncer gástrico y otras patologías gastrointestinales como la gastritis crónica, úlceras y linfoma MALT. Su prevalencia es mayor en países en vías de desarrollo que en países desarrollados. Emplea mecanismos patogénicos que le permiten colonizar la mucosa gástrica y producir una serie de alteraciones morfológicas que secuencialmente van desde la gastritis crónica, atrofia, metaplasia, displasia y adenocarcinoma.
