“…The endoscopic study allows a timely diagnosis and, consequently, removal of the localized primary tumor, contributing to the complete recovery of the patients. [4,27] Medina-Franco et al [20] obtained similar results that Oñate-Ocaña et al [15] when they studied patients with primary gastric non-Hodgkin lymphoma at earlier stages of cancer (I–II ~ 46%). The authors observed that surgical resection produced remission of cancer.…”

“…[1] The Mexican guidelines describe that open surgery or laparoscopic surgical resection are indicated in most cases where endoscopy does not achieve curative resection due to the high risk of lymph node metastases. [4] Although tumor resection aims to cure gastric adenocarcinoma, some cancers cannot be totally removed. [5] Currently, there are no records regarding the number of surgical resections or the impact of surgical procedures on the survival of GC patients in Mexico.…”

Background: Gastric cancer (GC) is one of the most frequent cancer types in Mexico. The primary method used as a treatment is surgical resection. The role of surgery in increasing survival is controversial. This study aimed to determine whether surgical resection increases the survival of patients with GC in a Mexican population. Methods: A systematic review of literature searches (Evidence-based MEDLINE/PubMed, Web of Science, Cochrane Library, and SciELO) and meta-analysis were performed based on the Preferred Reporting Items for Systematic Reviews and Meta-Analysis criteria. The published articles from 2000 to the current time were divided into cross-sectional and randomized studies. The inclusion criteria were survival, surgical resections, patients treated in Mexico, and primary GC. The effect estimation was calculated using the risk ratio (RR). The random-effects model and a confidence interval (CI) of 95% were used. Results: The RR of the pooled studies was 1.09 (95% CI, 0.71–1.67). RR of 0.82 (95% CI, 0.63–1.07) was obtained in cross-sectional studies, and randomized studies showed a RR of 2.08 (95% CI, 0.25–17.07). Conclusion: This work is the first systematic study that assesses the role of surgery on the survival of patients with GC in the Mexican population, the results showed that surgical resection did not improve survival in patients with GC.

“…A pesar de que México se considera un país con prevalencia intermedia para el cáncer gástrico, no existe una guía respecto a su detección en etapas iniciales. En 2018 se realizó un Consenso mexicano sobre detección y tratamiento del cáncer gástrico incipiente, basado en el diagnóstico del adenocarcinoma gástrico; establece recomendaciones sobre su escrutinio en sujetos con familiares de primer grado con el antecedente de cáncer gástrico, sin mencionar recomendaciones sobre cuándo o cómo iniciarlo 1 . Por otro lado, el Consenso mexicano sobre la dispepsia del 2017 establece que «la endoscopia debe realizarse en todo paciente con dispepsia no investigada que presenta síntomas y signos de alarma o falla a un tratamiento inicial orientado al síntoma predominante» 5 , como ocurrió con nuestro paciente.…”

Introducción: Los leiomiosarcomas gástricos son tumores extremadamente raros que abarcan del 0.1 al 3% de todas las lesiones gástricas malignas; su diagnóstico y tratamiento son aún un área gris en la medicina debido a su rareza. Objetivo: Documentar un caso clínico de leiomiosarcoma gástrico con metástasis pulmonares y mesentéricas. Métodos: Paciente de sexo masculino de 70 años con empeoramiento de dispepsia en tres meses. Resultados: La endoscopia reporta una lesión polipoide cuyo resultado inmunohistoquímico concluye leiomiosarcoma gástrico. Conclusiones: El leiomiosarcoma gástrico continúa siendo una entidad de suma rareza. Más reportes de casos son necesarios para mejorar su diagnóstico y tratamiento.

“…[24][25][26] This management algorithm is aligned with recent international guidelines proposing immediate endoscopic resection of dysplastic and neoplastic endoscopically visible lesions. [27][28][29][30] Pimentel-Nunes et al 31 in the latest guideline of MAPS II proposed by the European Society of Gastrointestinal Endoscopy established the current standards for the management of pre-neoplastic gastric lesions; highlighting that endoscopically visible dysplasia detected by high quality endoscopic techniques (chromoendoscopy/endoscopic magnification) should be eradicated after the endoscopic diagnosis due to the high risk of oncological progression to adenocarcinoma, and that close surveillance should be reserved only for patients with histopathologic diagnosis of dysplasia without an endoscopically visible focal lesion (LGD: every 12 mo; HGD: every 6 mo).…”

Background: The standard of practice when a superficial lesion was identified during upper GI endoscopy is to take an endoscopic forceps biopsy (EFB) of the lesion. The histopathologic findings then will determine the management plan. Endoscopic submucosal dissection (ESD) enables en-bloc resection for early neoplasms of the gastrointestinal tract and provides an adequate specimen that permits a more reliable histopathologic assessment. The objective of this study was to determine the rate of histopathologic discrepancy between EFB and specimens resected by ESD, and to identify the predisposing risk factors for this discordance.Materials and Methods: This is a retrospective study, enrolling patients with superficial gastric neoplasms that underwent EFB followed by ESD. We divided cases to concordant or discordant group according to the histopathologic diagnosis of EFB and ESD specimens. We also analyzed the features that may have influenced the occurrence of histopathologic discordance and the association between discordant samples of adenocarcinoma and neoplastic invasion to deeper layers.Results: A total of 115 gastric ESD procedures were performed with 84 patients meeting the inclusion criteria. Histopathologic discordance between EFB and ESD specimens were observed in 35.8% of cases (30/84 lesions). The univariant-bivariant analysis and multivariate logistic regression analysis showed that histologic discordance was closely related to the size of the lesions (P = 0.028). Conclusion:Histopathologic discrepancy between EFB and ESD specimens may occur in approximately one-third of cases, particularly for lesions over 20 mm, which may lead to crucial delays in gastric cancer precise diagnosis and treatment.
