RESUMEN
O câncer colorretal é desafiador devido à necessidade de atenção especializada nos serviços de saúde. Assim, objetivou-se analisar os fatores associados ao estadiamento do câncer colorretal (CCR) no estado do Maranhão, no Brasil. Trata-se de um estudo transversal, com abordagem quantitativa. Os dados foram coletados a partir do Sistema de Informação de Registro Hospitalar de Câncer, com a subsequente utilização do teste de qui-quadrado, considerando o nível de significância (p<0,05). Dos 421 casos de CCR analisados, houve predomínio de mulheres (57,8%), acima dos 60 anos (31,3%), de cor parda (68,2%), baixa escolaridade (43%) e múltiplas profissões. O adenocarcinoma foi o mais recorrente dos casos (73,5%) e, após tratamento com cirurgia e quimioterapia, houve remissão da doença em 27,2% e 37,9% dos casos, respectivamente. Houve associação do estadiamento tardio com tipo histológico adenocarcinoma (p<0,001), e os tratamentos recebidos nos casos tardios foram associados à cirurgia e quimioterapia (p<0,001). Os pacientes de casos precoces tiveram maiores possibilidades da remissão completa (p<0,000), sendo o tempo para o tratamento maior que 60 dias em casos tardios. As variáveis analisadas refletem principalmente a demora do diagnóstico, resultando na necessidade de tratamentos conjugados para efetiva possibilidade do desaparecimento da doença. Os casos analisados tiveram estadiamento tardio, o que reflete casos com diagnóstico e tratamento tardio, devido ao caráter silencioso da doença, à dificuldade de acesso dos pacientes aos serviços de saúde e à ainda recente estruturação dos fluxos de atendimento, medida que visa a reduzir a espera, identificar os casos precoces e favorecer melhores condições de tratamento para remissão da doença na população alvo.
Colorectal cancer is a challenge due to the need for specialized care in health services. Thus we aimed to analyze factors associated with colorectal cancer (CRC) staging in the state of Maranhão, Brazil. This is a cross-sectional study, with a quantitative approach. Data were collected from System Information of Hospital Cancer Registry, with subsequent use of the chi-square test, considering the significance level (p<0.05). Of the 421 cases of CRC analyzed, there was a predominance of women (57.8%), over 60 years (31.3%), mixed race (68.2%), low education (43%), and multiple professions. Adenocarcinoma was the most frequent case (73.5%) and, after treatment were treated with surgery and chemotherapy 27.2% and 37.9% of cases showed disease remission, respectively. There was an association between late staging and histological type of adenocarcinoma (p<0.001), and the treatments received in late cases were associated with surgery and chemotherapy (p<0.001). The patients with early cases had greater chances of complete remission (p<0.000), and the time to treatment was greater than 60 days in late cases. The analyzed variables mainly reflect the delay in diagnosis, requiring combined treatments for the effective possibility of healing the disease. The analyzed cases had late staging, which reflects in cases with late diagnosis and treatment, due to the silent nature of the disease, the difficulty of the patient's access to health services, and the recent structuring of service flow, a measure that aims to reduce waiting times, identify early cases and favor better treatment conditions for disease remission in the target population.
El cáncer colorrectal es un reto por la necesidad de atención especializada en los servicios sanitarios. Este trabajo buscó analizar los factores asociados con la estadificación del cáncer colorrectal (CCR) en el estado de Maranhão, Brasil. Se trata de un estudio transversal con enfoque cuantitativo. Los datos se recolectaron del Sistema de Información de Registro Hospitalario de Cáncer, en el que se utilizó la prueba de chi-cuadrado y el nivel de significancia (p<0,05). De los 421 casos de CCR evaluados, hubo predominio de mujeres (57,8%), mayores de 60 años (31,3%), de color pardo (68,2%), bajo nivel educativo (43%) y de múltiples profesiones. El adenocarcinoma fue el más común entre los casos (73,5%) y, tras el tratamiento con cirugía y quimioterapia, se produjo una remisión de la enfermedad en el 27,2% y el 37,9% de los casos. Hubo asociación entre la estadificación tardía con adenocarcinoma de tipo histológico (p<0,001), y los tratamientos que recibieron los casos tardíos se asociaron con cirugía y quimioterapia (p<0,001). Los pacientes con casos tempranos tuvieron mayores posibilidades de remisión completa (p<0,000), y el tiempo hasta el tratamiento fue superior a 60 días en los casos tardíos. Las variables analizadas reflejan principalmente el retraso en el diagnóstico, requiriendo tratamientos combinados para la posibilidad efectiva de desaparición de la enfermedad. Los casos analizados tuvieron estadificación tardía, lo que refleja casos con diagnóstico y tratamiento tardío debido al carácter silencioso de la enfermedad, el acceso de los pacientes a los servicios de salud y la reciente estructuración de los flujos de atención que apuntan a reducir la espera, identificar casos tempranos y favorecer un mejor tratamiento para la remisión de la enfermedad en la población objetivo.
RESUMEN
Introducción. El conjunto de estrategias de recuperación mejorada después de la cirugía (ERAS, por sus siglas en inglés) constituye un enfoque de atención multimodal y multidisciplinario, cuyo propósito es reducir el estrés perioperatorio de la cirugía, disminuir la morbilidad y acortar la estancia hospitalaria. Este estudio tuvo como objetivo describir los resultados clínicos de pacientes sometidos a cirugía por cáncer colorrectal, identificando las complicaciones principales y los factores perioperatorios relacionados con el alta temprana. Métodos. Se analizaron los pacientes consecutivos sometidos a cirugía colorrectal entre los años 2020 y 2023, todos los cuales siguieron el protocolo ERAS institucional. Se evaluaron las características clínicas, los factores perioperatorios, los desenlaces postoperatorios y la tasa global de adherencia al protocolo. Resultados. Un total de 456 pacientes fueron sometidos a cirugía colorrectal, 51% de sexo masculino, con edad media de 60 años. La mayoría de las intervenciones se realizaron por laparoscopia (78 %), con una tasa de conversión del 14,5 %. Las complicaciones postoperatorias incluyeron fuga anastomótica (4,6 %), sangrado, infección intraabdominal y obstrucción intestinal. La estancia hospitalaria promedio fue de 4 días y la mortalidad del 2,8 %. La tasa global de adherencia al protocolo ERAS fue del 84,7 %. Conclusiones. El enfoque combinado de cirugía laparoscópica y protocolo ERAS es factible, seguro y se asocia con una estancia hospitalaria más corta. La implementación y adherencia al protocolo ERAS no solo mejora los resultados postoperatorios, sino que también resalta la importancia de acceder a datos sólidos, permitiendo mejorar la atención perioperatoria local.
Introduction. The Enhanced Recovery After Surgery (ERAS) protocol is a multimodal, multidisciplinary approach to care, the purpose of which is to reduce the perioperative stress of surgery, decrease morbidity, and shorten hospital stay. This study aimed to describe the clinical outcomes of patients undergoing surgery for colorectal cancer, identifying the main complications and perioperative factors related to early discharge. Methods. Consecutive patients undergoing colorectal surgery between 2020 and 2023 were analyzed, who followed the institutional ERAS protocol. Clinical characteristics, perioperative factors, postoperative outcomes, and overall protocol adherence rate were evaluated. Results. A total of 456 patients underwent colorectal surgery, 51% male, with a mean age of 60 years. Most interventions were performed laparoscopically (78%), with a conversion rate of 14.5%. Postoperative complications included anastomotic leak (4.6%), followed by bleeding, intra-abdominal infection, and intestinal obstruction. The average hospital stay was 4 days and mortality was 2.8%. The overall adherence rate to the ERAS protocol was 84.7%. Conclusions. The combined approach of laparoscopic surgery and ERAS protocol is feasible, safe, and associated with a shorter hospital stay. Implementation and adherence to the ERAS protocol not only improves postoperative outcomes, but also highlights the importance of accessing solid data, allowing for improved local perioperative care.

Abstract Objective: To determine the branching patterns of the inferior mesenteric artery (IMA) and to describe the clinical applicability of computed tomography (CT) angiography in the evaluation of these vessels to facilitate the planning of colorectal cancer surgery. Materials and Methods: We included 100 patients who underwent CT angiography of the abdomen and pelvis. The branching patterns of the IMA were examined and classified as type 1 (bifurcated), including 1A (sigmoid and left colic arteries arising from a common trunk), 1B (sigmoid and superior rectal arteries arising from a common trunk) and 1C (sigmoid arteries arising from both trunks); type 2 (trifurcated); and type 3 (no left colic branch). Results: Among the 100 patients evaluated, we found the variant to be type 1A in 9%, type 1B in 47%, type 1C in 24%, type 2 in 16%, and type 3 in 4%. Conclusion: Preoperative CT angiography for evaluating the IMA branching pattern could inform decisions regarding the surgical approach to colorectal cancer.

Now with favorable evolution and improvement of her symptoms.
RESUMEN
ABSTRACT Background: Colorectal cancer (CRC) has high mortality rates worldwide. In Brazil, it is the second most common cancer in both sexes. Delay in detecting premalignant lesions contributes to increased morbidity and mortality. In this scenario, the Piranhas project was created to track CRC in a low-income population in the hinterland of Alagoas. Objective: The study aimed to establish the main strategies and verify the feasibility of implementing a CRC tracking program and demonstrate the results obtained in the CRC Prevention Campaign in Piranhas/AL. Methods: The program took place in Piranhas, Alagoas, Brazil, through public-private partnerships. Individuals aged between 50 and 70 years of age were included for screening with a fecal occult blood test (FOBT) and colonoscopy in positive cases. Patient data were collected on standard forms. Results: A total of 2152 patients, aged between 50 and 70 years, were screened, 130 of which underwent colonoscopy. Several preneoplastic lesions were detected in 58 patients. The adenoma detection rate (ADR) was 33.85%. Conclusion: The study proved to be effective and viable since 44.6% of the program participants, who underwent screening with FOBT, followed by colonoscopy in positive cases, had some type of preneoplastic lesion. In addition, the program generated a significant social impact on the population of Piranhas due to the opportunity to diagnose and treat CRC precursor lesions.
RESUMO Contexto: O câncer colorretal (CCR) possui altas taxas de mortalidade em todo mundo. No Brasil é o segundo câncer mais comum em ambos os sexos. O atraso na detecção de lesões pré-malignas contribui com o aumento da morbimortalidade. Neste cenário, o projeto Piranhas foi criado para rastrear o CCR em uma população carente do sertão alagoano. Objetivo: O estudo teve como meta estabelecer as principais estratégias e verificar a viabilidade da implementação de um programa de rastreamento do CCR, assim como demonstrar os resultados obtidos na Campanha de prevenção de CCR no município de Piranhas/AL. Métodos: O programa aconteceu em Piranhas, Alagoas, Brasil, através de parcerias público-privadas. Foram incluídos indivíduos entre 50 e 70 anos para triagem com pesquisa de sangue oculto nas fezes (PSOF) e colonoscopia dos casos positivos. Os dados dos pacientes foram coletados em formulários padrão. Resultados: Foram rastreados um total de 2152 pacientes com idade entre 50 e 70 anos, sendo destes, 130 submetidos à colonoscopia. Várias lesões pré-neoplásicas foram detectadas em 58 pacientes. A taxa de detecção de adenoma foi de 33,85%. Conclusão: O estudo demonstrou-se eficaz e viável, uma vez que 44,6% dos participantes do programa que realizaram a triagem com PSOF seguido de colonoscopia nos casos positivos apresentava algum tipo de lesão pré-neoplásica. Além disso, o programa gerou grande impacto social na população de Piranhas, pela oportunidade de diagnóstico e tratamento de lesões precursoras do CCR.
RESUMEN
Fundamento aún no se ha establecido una técnica ideal que permita realizar el cierre laparotómico que garantice la disminución de complicaciones. Objetivo comparar los resultados del cierre de la pared abdominal mediante puntos subtotales internos y puntos totales en pacientes intervenidos por cáncer colorrectal. Métodos: se realizó un estudio descriptivo, prospectivo y transversal en el Hospital General Docente Dr. Enrique Cabrera, en el trienio 2019-2021, con 80 pacientes intervenidos por cáncer colorrectal. Se empleó la prueba Chi-cuadrado, la prueba exacta de Fisher y la prueba U de Mann-Whitney, entre otros. Resultados el tumor se localizó en colon sigmoide en 35 % de los casos de los pacientes con cierre de puntos totales; y en 31,7 % del grupo con cierre mediante puntos subtotales. La cirugía fue urgente en 80 % del grupo con cierre de puntos totales; y electiva en 75 % de los de cierre con puntos subtotales. La incisión fue media supra e infraumbilical en 70 % de los pacientes del grupo con cierre de puntos totales; y xifopubiana en 66,7 % de los del cierre con puntos subtotales. Se presentaron medianas de 3 ± 2 y 1 ± 0 complicaciones para los de cierre con puntos totales y cierre con puntos subtotales, respectivamente. La mediana de la estadía hospitalaria fue mayor en el grupo con cierre de puntos totales (8 ± 6 días). Conclusiones en los pacientes donde se aplicaron puntos subtotales internos para el cierre de la pared abdominal, los resultados fueron mejores que en grupo donde se emplearon puntos totales.
Foundation an ideal technique has not been established yet to allow laparotomic closure to guarantee the reduction of complications. Objective to compare the results of abdominal wall closure using internal subtotal points and total points in patients operated on for colorectal cancer. Methods a descriptive, prospective and cross-sectional study was carried out at the Dr. Enrique Cabrera General Teaching Hospital, from 2019 to 2021, with 80 patients operated on for colorectal cancer. The Chi-square test, Fisher's exact test and the Mann-Whitney U test, among others, were used. Results the tumor was located in the sigmoid colon in 35% of patients with total suture closure; and in 31.7% of the group with closure by subtotal points. Surgery was urgent in 80% of the group with total stitch closure; and elective in 75% of the closing cases with subtotal points. The incision was median supra and infraumbilical in 70% of the patients in the group with total suture closure; and xiphopubic in 66.7% of those at closure with subtotal points. There were medians of 3 ± 2 and 1 ± 0 complications for closure with total stitches and closure with subtotal stitches, respectively. Median hospital stay was longer in the total stitch closure group (8 ± 6 days). Conclusions in the patients where internal subtotal sutures were applied for abdominal wall closure, the results were better than in the group where total sutures were used.
RESUMEN
Cáncer colorrectal post-colonoscopia (CCRP) es el tumor que aparece posterior a una colonoscopia normal antes de cumplirse el tiempo establecido para seguimiento endoscópico. Origen multifactorial, refleja la calidad de la colonoscopia y las diferentes biologías tumorales entre los cánceres colorrectales detectados (CCRD) y el CCRP. Nuestro objetivo es describir las características del CCRP en nuestro medio, identificar factores de riesgo, discriminar sus causas según la Organización Mundial de Endoscopia (OME) y determinar el efecto en la sobrevida del paciente. El estudio se realizó en pacientes con cáncer-colorrectal (CCR) atendidos en consulta de gastro-oncología de dos instituciones en Medellín-Colombia, entre enero de 2012 y diciembre de 2021 que se habían sometido a una colonoscopia en los 6 a 36 meses anteriores a la colonoscopia en la que se diagnosticó el CCR. 919 pacientes durante 10 años por CCR, 68 casos de CCRP (6,9%), se encontró que se presenta con más frecuencia en pacientes mayores (74 vs. 66 años; p=0,03), con antecedentes de pólipos adenomatosos (36,8% vs. 20,1%; p=0,01) y en colon derecho (57,4% vs. 40,6%; p=0,006), con una tendencia en pacientes con diverticulosis (41,2% vs. 31,3%; p=0,05) y diabetes (25% vs. 14%; p=0,06); menor sobrevida a 5 y 10 años (58%-55,2% vs. 67%-63%; p<0,001). Según la OME, los CCRP se presentaron en 61,3% por lesiones omitidas en colonoscopias inadecuadas, 29% colonoscopias adecuadas y 9,7% resecciones incompletas de adenomas. En conclusión, la tasa de CCRP fue de 6,9%, con mayor propensión en pacientes de mayores, antecedente de resección de pólipos, y en colon derecho. Acorde a la OME, las lesiones omitidas más frecuentemente se relacionaron con colonoscopias inadecuadas. Los pacientes con CCRP tienen menor sobrevida.
Post-colonoscopy colorectal cancer (PCCRC) is a tumor that appears after a normal colonoscopy before the established time for the endoscopic follow up. Its origin reflects the quality of the colonoscopy and the different tumoral biologics between the CRC and the CRCPC. Our aim is to describe the characteristics of the PCCRC in our region, to identify risk factors, to discriminate the potential causes according to the World Endoscopý Organization (WEO) and to determine its impact in the patient's survival. We studied patients with colorectal cancer (CRC) attended at the gastro-oncology clinic of two institutions of Medellin-Colombia, between January 2012 and December 2021 that had been submitted to a colonoscopy between 6-36 months before the colonoscopy in which the CRC was diagnosed. 919 patients during 10 years for CRC, 68 cases of PCCRC (6.9%); It was more frequent in older patients (74 vs. 66 years; p=0.03), with background of adenomatous polyps (36.8% vs. 20.1%; p=0.01) and in right colon (57.4% vs. 40.6%; p=0.006), with a tendency in patients with diverticulosis (41.2% vs. 31.3%; p=0.05) and diabetes (25% vs. 14%; p=0.06); less survival at 5 and 10 years (58% and 55.2% vs. 67% and 63%; p<0.001). According to the WEO, the PCCRC presents in 61.3% because of abnormal findings omitted in inadequate colonoscopies, 29% in a suitable colonoscopy and 9.7% incomplete resections of adenomas. In conclusion, the rate of PCCRC was 6.9% with more propension in older patients, a background of polyp resection, and proximal colon. According to the WEO, the abnormal findings omitted more frequently were related with inadequate colonoscopies. The patients with PCCRC had less survival.
RESUMEN
El cáncer colorrectal (CCR) durante el embarazo es una neoplasia poco frecuente, con una incidencia entre el 0,07- 0,1% en la población. Para un diagnóstico preciso es necesaria una alta sospecha y con ello realizar pruebas diagnósticas oportunas. Cuando no se tiene sospecha ni se busca el diagnóstico, el pronóstico suele ser malo, ya que muchas veces se halla en estado avanzado. Presentamos los casos de dos gestantes de 27 y 31 años, diagnosticadas de adenocarcinoma colorrectales medianamente diferenciados a las 29 y 30 semanas de gestación, respectivamente. Debido a la importancia de realizar un diagnóstico oportuno para mejorar la sobrevida de las pacientes, se realizó una búsqueda de información en la literatura en relación con el diagnóstico, manejo y pronóstico de esta patología.
Colon rectal cancer (CRC) during pregnancy is a rare neoplasia, with an incidence between 0.07-0.1% in the population. For an early diagnosis, a high suspicion is necessary and with it, timely diagnostic tests are carried out. When there is no suspicion and no diagnosis is sought, the prognosis is usually poor since it is often in an advanced state. We present the cases of two pregnant women aged 27 and 31 diagnosed with moderately differentiated colorectal adenocarcinoma at 29 and 30 weeks of gestation, respectively. Due to the importance of making an opportune diagnosis to improve the survival of the patients, a search of information was carried out in the literature in relation to the diagnosis, management and prognosis of this pathology.

Introducción. La fuga anastomótica es la complicación más grave del tratamiento quirúrgico del cáncer de colon por su alta morbimortalidad. El diagnóstico evidente, manifestado por la salida de contenido intestinal por drenajes o la herida quirúrgica, ocurre tardíamente (entre el 6º y 8º día). El objetivo de este trabajo fue estudiar la variación de los valores de la proteína C reactiva postoperatoria para hacer un diagnóstico precoz. Métodos. Estudio observacional, analítico, retrospectivo, de una cohorte de pacientes con neoplasia, en quienes se realizó cirugía oncológica con anastomosis intestinal, entre enero de 2019 y diciembre de 2021. Se midieron los valores en sangre de proteína C reactiva postoperatoria (1°, 3° y 5° días). Resultados. Se compararon 225 casos operados que no presentaron fuga con 45 casos con fuga. En los casos sin fuga, el valor de proteína C reactiva al 3º día fue de 148 mg/l y al 5º día de 71 mg/l, mientras en los casos con fuga, los valores fueron de 228,24 mg/l y 228,04 mg/l, respectivamente (p<0,05). Para un valor de 197 mg/l al 3º día la sensibilidad fue de 77 % y para un valor de 120 mg/l al 5º día la sensibilidad fue de 84 %. Conclusión. El mejor resultado de proteína C reactiva postoperatoria para detectar precozmente la fuga anastomótica se observó al 5º día. El valor de 127 mg/l tuvo la mejor sensibilidad, especificidad y valor predictivo negativo, lo cual permitiría el diagnóstico temprano y manejo oportuno de esta complicación
Introduction. Anastomotic leak is the most serious complication of surgical treatment of colon cancer due to its high morbidity and mortality. The obvious diagnosis manifested by the exit of intestinal content through drains or the operative wound, occurs late (between the 6th and 8th day). The objective of this work was to study the postoperative C-reactive protein values to make an early diagnosis. Methods. Observational, analytical, retrospective study of a cohort of patients undergoing colorectal surgery for neoplasia, between January 2019 and December 2021, who underwent oncological surgery with intestinal anastomosis and measured CRP blood values on 1st, 3rd and 5th post-operative days. Results. Two-hundred-twenty-five operated cases that did not present leaks were compared with 45 cases with leaks, with CRP values on the 3rd and 5th day of 148mg/l and 71mg/l in cases without leakage and CRP values of 228.24mg/l and 228.04 mg/l in cases with leakage on the 3rd and 5th day, respectively (p<0.05), CRP value of 197mg/l on the 3rd day has a sensitivity of 77%; CRP value of 120mg/l on the 5th day, has a sensitivity of 84%. Conclusions. The best result for CPR to early diagnosis of anastomotic leak was observed on the 5th day, having the value of 127 mg/l the best sensitivity, specificity and NPV, which would allow early diagnosis and timely management

SUMMARY OBJECTIVE: Colorectal cancer is the third most diagnosed malignant neoplasm in the world and the fourth leading cause of cancer mortality. The loss of muscle mass in oncological patients is the main aspect of cancer-related malnutrition. Associations between sarcopenia and poor outcomes, such as high postoperative mortality, chemotherapy toxicity, and reduced survival, have been recently described. The aim of this study was to prospectively assess the prevalence of preoperative sarcopenia in patients with colorectal cancer using validated methods to evaluate muscle strength, muscle mass, and physical performance. METHODOLOGY: This study included patients with colorectal cancer undergoing oncological staging at a Cancer Center in Brazil from May 2019 to March 2020 who had images from abdominal computed tomography available for analysis of body composition. The muscle strength test, physical performance, referred fatigue, and clinical and nutritional data were evaluated. RESULTS: A total of 31 patients were included, and most were diagnosed with colon cancer (77.4%) and clinical stage II in 41.9% of cases. The prevalence of probable sarcopenia was 22.6%; of these patients, sarcopenia was confirmed in 19.4%, and ultimately, 9.7% of the sample was classified as severe sarcopenia. We did not find a significant association between the presence of sarcopenia in our sample and age, sex, tumor staging, nutritional characteristics, referred patient fatigue, or postoperative complications. CONCLUSION: Considering the criteria established by the EWGSOP, the prevalence of preoperative sarcopenia in colorectal cancer patients was 19.4%.
RESUMEN
El cáncer colorrectal (CCR) es una de las causas más frecuentes de mortalidad por cáncer en el mundo. Las lesiones serradas son responsables de 10 a 20% de todos los CCR. Los pólipos serrados, en particular los adenomas serrados sésiles (ASS) y adenomas serrados tradicionales (AST), tienen una apariencia sutil y localización proximal, y por ello presentan una alta tasa de lesiones perdidas. El objetivo de la presente revisión fue evaluar la evidencia disponible sobre el uso de diversas intervenciones endoscópicas para mejorar la tasa de detección de las lesiones serradas, para de esta forma, disminuir la mortalidad relacionada al CCR.
Colorectal cancer (CRC) is one of the most common causes of cancer mortality in the world. Serrated lesions are responsible for 10 to 20% of all CRCs. Serrated polyps, particularly sessile serrated adenomas (SSA) and traditional serrated adenomas (TSA), have a subtle appearance and proximal location, and therefore have a high miss rate. The objective of this review was to evaluate the available evidence on the use of various endoscopic interventions for improving serrated lesion detection rate, thus reducing CRC related mortality.
RESUMEN
O⁃glycosylation is a common post⁃translational modification of mucins, widely present in both normal and tumor cells. In colorectal cancer (CRC) cells, there is a varying degree of dysregulation in O ⁃ glycosylation ⁃ related glycosyltransferases, molecular chaperones, and surface Tn antigen, sTn antigen, and T antigen. These dysregulations play a distinctive role in the occurrence and development of CRC, including invasion and metastasis, abnormal apoptosis and proliferation, immune escape, etc. They are extensively studied as novel tumor biomarkers and potential therapeutic targets. This article provides a comprehensive review of progress of research on mucin⁃type O⁃glycosylation and its relevance to the occurrence and development of CRC and its clinical application.
RESUMEN
Background: The terminology of nonalcoholic fatty liver disease (NAFLD) was changed to metabolic dysfunction ⁃ associated fatty liver disease (MAFLD) in 2020. NAFLD has been confirmed to be a risk factor for colorectal neoplasms, but the association between MAFLD and colorectal neoplasms is conflicting. Aims: To investigate the correlation of MAFLD with colorectal adenoma and early colorectal cancer. Methods: The clinical information of 701 patients who met the criteria and were admitted to Renmin Hospital of Wuhan University from January 2021 to August 2021 was collected retrospectively. Among them, 274 colorectal adenoma patients with low ⁃ grade intraepithelial neoplasia or without intraepithelial neoplasia were classified as adenoma group, 21 patients with high ⁃ grade intraepithelial neoplasia, intramucosal carcinoma, and submucosal carcinoma were classified as early cancer group, and 406 patients with normal colonoscopy or non⁃adenomatous polyps were served as control group. The general information and prevalence of MAFLD between these groups were compared. Furthermore, the correlation of MAFLD with colorectal adenoma and early colorectal cancer, and the gender difference of these correlations were analyzed by Logistic regression models. Subgroup analysis was performed based on the clinicopathological characteristics of colorectal adenoma. Results: When adjusting the confounding variables including gender, age, smoking, alcohol drinking, diabetes, hypertension, and serum creatinine, MAFLD was significantly associated with the prevalence of colorectal adenoma (OR=1.83, 95% CI: 1.04 ⁃ 3.22, P=0.037) and early colorectal cancer (OR=3.91, 95% CI: 1.14⁃13.42, P=0.031). When stratified as gender, the significant association remained in females (OR=4.04, 95% CI: 1.56 ⁃ 10.47, P=0.004), but not in males. In addition, no correlation was found between MAFLD and the location, size, number, and advanced histology of colorectal adenoma (all P>0.05). Conclusions: MAFLD is an independent risk factor for colorectal adenoma and early colorectal cancer. MAFLD is specifically associated with increased risk of colorectal adenoma in females but not in males.

RESUMEN
Colorectal serrated lesions are a group of polyps/adenomas with serrated architecture, including hyperplastic polyp, sessile serrated lesion and sessile serrated lesion with dysplasia, traditional serrated adenoma, and unclassified serrated adenoma. Sessile serrated lesion and traditional serrated adenoma are precursors of serrated lesions progressing to colorectal cancer. Serrated lesions are characterized by genetic (BRAF or KRAS gene mutations) and epigenetic (CpG island methylator phenotype) alterations that synergistically drive colorectal mucosa to develop polyps or adenomas, and with malignant transformation into colorectal cancer. The complexity of serrated lesion makes it difficult to diagnose, easy to miss diagnosis and has a high malignant rate. This article reviewed the advances in research on colorectal serrated lesions from the aspects of endoscopic, pathological and molecular features.
RESUMEN
Patients with inflammatory bowel disease (IBD) are at a significantly increased risk of colitis-associated colorectal cancer (CAC). The relationship between intestinal flora metabolites and CAC has attracted much attention. Regulating intestinal flora metabolism or increasing beneficial metabolites may play an important role in preventing CAC. This article reviewed the role of intestinal flora metabolites in CAC.
RESUMEN
Objective:Three-dimensional simulation modeling technology was used to conduct three-dimensional reconstruction, classification and measurement for the anatomic structures of colorectal canal, tumor and key blood vessels in patients with rectal cancer before operation. And the accuracy of the data and information obtained for the prediction of anastomotic tension, important types of vascular variant, positioning of anatomical landmarks, etc. in laparoscopic-assisted radical resection of rectal cancer, and the guiding effect of operation was evaluated.Methods:The clinical data of 50 patients with laparoscopic-assisted radical resection of rectal cancer treated in the General Surgery Department, Beijing Ditan Hospital Capital Medical University from January 2019 to February 2021 were analyzed retrospectively, including 31 males and 19 females, aged from 42 to 83 years old, with an average age of (62.72 ±15.21) years. The patients were divided into two groups according to whether the patients underwent three-dimensional simulation reconstruction before operation. The patients who underwent abdomen pelvic enhancement CT and further three-dimensional reconstruction before surgery were taken as reconstruction group ( n=24), and the patients who were only routinely performed abdomen pelvic enhancement CT before operation were taken as control group ( n=26). For the patients in the reconstruction group, the CT images were modeled by Mimics software before operation, and the key data such as the length of colorectal and tumor, the correlation length of rigid structure of pelvic wall, the length of inferior mesenteric artery (IMA) from the bifurcation point of left and right arteria iliaca communis, the type and proportion of IMA variation, the length of left colonic artery (LCA) from the beginning of IMA and the distance between LCA and IMV were measured, and the consistency correlation coefficient (CCC) was analyzed with the actual data obtained during operation. And then the accuracy of three-dimensional simulation modeling technology for surgical guidance was evaluated. MedCalc 19.0 software was used for statistical analysis. Results:In the reconstruction group, regarding the data of each dimension of the model (intestinal tract, pelvic cavity, blood vessels) and the corresponding structural measurements during the operation, the consistent correlation coefficient (CCC) evaluation was more than 0.9. One case was predicted to have free splenic flexure of colon and one case actually had free splenic flexure of colon. The prediction accuracy was 100%. The IMA variants in the reconstruction group were divided into 4 types, all of which were verified by operation. Compared with the control group, the operation time ( P=0.011) and the location time (IMA, P=0.043; LCA, P=0.007; IMV, P=0.034) of each vessel in the reconstruction group were shorter, and the amount of intraoperative blood loss was less ( P=0.017). Conclusion:The application of three-dimensional simulation modeling technology before operation is helpful for the operator to accurately predict the intraoperative anastomotic tension, the type of IMA variation and the related diameter length, based on which the accurate operation plan can be made to guide the operation.
RESUMEN
Objective: To demonstrate the disease burden and epidemiological characteristics of colorectal cancer in different regions by analyzing the incidence and mortality data in China and worldwide in 2020. Methods: Estimation of the incidence and mortality data of colorectal cancer were obtained from the GLOBOCAN 2020 database. The incidence, death, age standardized incidence rate (ASIR) and age standardized mortality rate (ASMR) of colorectal cancer in China and 20 regions in the world were compared. The correlation between the Human Development Index (HDI) and ASIR/ASMR was analyzed. Results: In 2020, the number of new cases of colorectal cancer in the world reached 1 931 600, and the number of deaths reached 935 200. The incidence and mortality in all regions of the world continued to rise in the age group above 50 years old. The morbidity and mortality in male were higher than those in female. East Asia ranked the highest number of incidence cases and deaths in the world, which were 740 000 and 360 100 respectively. There were significant differences in incidence and mortality among regions in the world. The highest ASIR and ASMR were observed in Northern Europe (33.61/100 000) and Eastern Europe (14.53/100 000), whereas the lowest ASIR and ASMR were both observed in South-Central Asia (5.46/100 000 and 3.16/100 000). HDI had significant exponential relationship with ASIR (r(2)=0.59, P<0.001) and ASMR (r(2)=0.38, P<0.001). There were 555 500 new cases and 286 200 death cases of colorectal cancer in China, accounting for about 30% of the world and more than 75% of East Asia. The ASIR of China was 24.07/100 000, ranking at the medium level, while the ASMR was 12.07/100 000, ranking at the high level of world. Conclusion: The incidence and mortality of colorectal cancer are highly correlated with HDI. China is one of the countries with the heaviest disease burden of colorectal cancer in the world.

Objective: To investigate the effect of rigosertib (RGS) combined with classic chemotherapy drugs including 5-fluorouracil, oxaliplatin, and irinotecan in colorectal cancer. Methods: Explore the synergy effects of RGS and 5-fluorouracil (5-FU), oxaliplatin (OXA), and irinotecan (IRI) on colorectal cancer by subcutaneously transplanted tumor models of mice. The mice were randomly divided into control group, RGS group, 5-FU group, OXA group, IRI group, 5-FU+ RGS group, OXA+ RGS group and IRI+ RGS group. The synergy effects of RGS and OXA on KRAS mutant colorectal cancer cell lines in vitro was detected by CCK-8. Ki-67 immunohistochemistry and TdT-mediated dUTP nick-end labeling (TUNEL) staining were performed on the mouse tumor tissue sections, and the extracted tumor tissue was analyzed by western blot. The blood samples of mice after chemotherapy and RGS treatment were collected, blood routine and liver and kidney function analysis were conducted, and H&E staining on liver sections was performed to observe the side effects of chemotherapy and RGS. Results: The subcutaneously transplanted tumor models were established successfully in all groups. 55 days after administration, the fold change of tumor size of OXA+ RGS group was 37.019±8.634, which is significantly smaller than 77.571±15.387 of RGS group (P=0.029) and 92.500±13.279 of OXA group (P=0.008). Immunohistochemical staining showed that the Ki-67 index of tumor tissue in control group, OXA group, RGS group and OXA+ RGS group were (100.0±16.8)%, (35.6±11.3)%, (54.5±18.1)% and (15.4±3.9)%, respectively. The Ki-67 index of OXA+ RGS group was significantly lower than that in control group (P=0.014), but there was no significant difference compared to OXA group and RGS group (OXA: P=0.549; RGS: P=0.218). TUNEL fluorescence staining showed that the apoptotic level of OXA+ RGS group was 3.878±0.547, which was significantly higher than 1.515±0.442 of OXA group (P=0.005) and 1.966±0.261 of RGS group (P=0.008). Western blot showed that the expressions of apoptosis related proteins such as cleaved-PARP, cleaved-caspase 3 and cleaved-caspase 8 in the tumor tissues of mice in the OXA+ RGS group were higher than those in control group, OXA group and RGS group. After the mice received RGS combined with chemotherapy drugs, there was no significant effect on liver and kidney function indexes, but the combined use of oxaliplatin and RGS significantly reduced the white blood cells [(0.385±0.215)×10(9)/L vs (5.598±0.605)×10(9)/L, P<0.001] and hemoglobin[(56.000±24.000)g/L vs (153.333±2.231)g/L, P=0.001] of the mice. RGS, chemotherapy combined with RGS and chemotherapy alone did not significantly increase the damage to liver cells. Conclusions: The combination of RGS and oxaliplatin has a stronger anti-tumor effect on KRAS mutant colorectal cancer. RGS single agent will not cause significant bone marrow suppression and hepatorenal injury in mice, but its side effects may increase correspondingly after combined with chemotherapy.
