RESUMEN
BACKGROUND: Early-onset colorectal cancer (EO-CRC) is defined as colorectal cancer diagnosed before the age of 50 years, and its incidence has been increasing over the last decade, now accounting for 10% of all new CRC diagnoses. Average-onset colorectal cancer (AO-CRC) has shown a steady decline in its incidence and related mortality over the past 20 years. The disparities in outcomes and overall survival (OS) between EO-CRC and AO-CRC are controversial. Our study compared OS and cause-specific survival (CSS) between metastatic EO-CRC (mEO-CRC) and metastatic AO-CRC (mAO-CRC) and identified the associated factors. METHODS: Data on patient characteristics, tumor characteristics, incidence, and mortality were obtained from the SEER database from 2010 to 2020. We identified 23,278 individuals aged > 18 years with a confirmed diagnosis of all histological subtypes of metastatic CRC (M1 on TNM stage) using ICD-O-3 site codes. mEO-CRC and mAO-CRC were compared. OS distributions and CCS were analyzed using the Kaplan-Meier method and log-rank test to assess differences. A Cox regression model was used to assess the associations between variables. RESULTS: mEO-CRC constituted 17.79% of the cases, whereas 82.21% had mAO-CRC. Most patients with mEO-CRC were 45-49 years old (47.66%), male (52.16%) and White (72.57%) and had adenocarcinoma histology (87.30%). Left colon tumors were most prevalent in both groups (40.26%) but were more prevalent in mEO-CRC patients than in mAO-CRC patients (49.63% vs. 38.23%, p < 0.001). Patients with mEO-CRC had higher OS (p < 0.001) and CSS (p < 0.001) than those with mAO-CRC. Patients with mEO-CRC also had significantly better median overall survival (30 months vs. 18 months, p < 0.001). The factors associated with worse OS included mAO-CRC (p < 0.001), mucinous adenocarcinoma (p < 0.001), male sex (p = 0.003), and a lack of surgical intervention (p < 0.001). CONCLUSIONS: Most patients with mEO-CRC fall within the range of 45 to 49 years of age. Patients with mEO-CRC were more likely to receive cancer-directed therapy (including chemotherapy and radiotherapy) and had better OS and CSS than those with mAO-CRC. This is likely attributable to the better performance status, fewer comorbidities, and better tolerance to cancer-directed therapy in mEO-CRC patients. The factors associated with worse OS and CSS were age > 50 years, mucinous adenocarcinoma, male sex, and no surgical treatment.
RESUMEN
AIM: To evaluate the association between elevated serum transaminase levels and insulin resistance (IR) in a population of healthy individuals. METHODS: We define IR with a cut-off point of homeostatic model assessment (HOMA-IR) ≥ 3.8. For aspartate aminotransferase (AST), we consider elevated values >30 U/L in women and values >36 U/L in men. For alanine aminotransferase (ALT), we consider elevated values >30 U/L in women and values >40 U/L in men. We performed a crude and adjusted generalized linear model from Poisson family with robust variance, in order to evaluate the association between elevated serum transaminase levels and IR. The associations were presented as prevalence ratio (PR) with their respective 95% confidence intervals (95% CI). RESULTS: We included 261 participants in the study. The median age was 39 years (31-45) and 23.7% of the participants were men. The prevalence of elevated serum transaminase for AST and ALT were, 13.8% and 26.1%, respectively. The prevalence of IR was 34.1%. In the crude analysis we found statistical significance between elevated AST and ALT with IR (PR = 3.18; 95% CI: 2.33-4.34 and PR = 2.44; 95% CI: 1.88-3.30; respectively). However, in the multivariate analysis, the association only remained statistically significance with ALT, but lost its significance with AST, PR = 1.90; CI 95%: 1.31-2.77 and a PR = 1.23; CI 95%: 0.93-1.61; respectively. CONCLUSION: Elevated serum levels of ALT were associated with insulin resistance. ALT could be used in clinical practice as an additional tool to assess IR in apparently healthy people.

OBJECTIVE: The purpose of this study was to determine the prevalence of the different types of gastric polyps in the Daniel Alcides Carrión Hospital between the years of 2014 and 2016, and also define the endoscopic and histopathological characteristics of the lesions. MATERIALS AND METHODS: 7559 endoscopic reports were reviewed, in which 148 gastric polyps were found. The patients age and sex as well as the localization, number, size and macroscopic and microscopic aspects of the polyps were recorded. RESULTS: The prevalence of gastric polyps was 1.9%; 74.3% of these were found in women with an average age of 61.5 years. 59.4% of the gastric polyps found were singular, and the majority were located on the body and antrum of the stomach. 74.29% of the polyps were less than 1 cm in diameter and 83.64% of these were sessile when seen macroscopically. According to the histological type, it was found that the majority of gastric polyps were hyperplasic (76.4%), followed by fundic gland polyps (17.5%) and gastric adenomas (6.1%). It was also found that multiple gastric polyps were associated with fundic gland polyps while singular polyps were most likely hyperplastic or adenomas. CONCLUSION: The prevalence of fundic gland polyps has increased, while the other types of polyps have maintained their estimated prevalence.

Objetivos: El propósito de este estudio fue determinar la prevalencia y las características endoscópicas e histopatológicas de los distintos tipos de pólipos gástricos en el Hospital Daniel Alcides Carrión entre los años 2014-2016. Materiales y métodos: Se revisó 7559 reportes endoscópicos, donde se encontró 148 pólipos gástricos y se consignó datos de edad, sexo, localización, número de lesiones, tamaño, y aspectos macroscópicos y microscópicos de la lesión. Resultados: La prevalencia de pólipos gástricos fue 1,9%; el 74,3% de estos se presentaron en mujeres donde la edad promedio fue de 61,5 años. El 59,46% de los pólipos gástricos fueron únicos, la mayoría localizándose en el antro y cuerpo del estómago. El 74,29% de pólipos fueron menores de 1 cm en diámetro y el 83,64% tenían un aspecto macroscópico sésil. Con respecto al tipo histológico, se encontró que la mayoría de los pólipos gástricos en esta población son hiperplásicos (76,4%), seguidos por los de glándulas fúndicas (17,5%) y la minoría fueron adenomas (6,1%). Cabe resaltar que los pólipos múltiples fueron en su gran mayoría de tipo de glándulas fúndicas mientras que en los demás tipos histológicos predominó el pólipo único. Conclusión: La prevalencia de pólipos de glándulas fúndicas ha aumentado, mientras los otros tipos de pólipos han mantenido su prevalencia esperada.
