Fusobacterium nucleatum, a key oral-pathobiont in colorectal cancer (CRC), has evolved from a presumed “passenger” to an active “co-conspirator” in tumorigenesis. This review systematically delineates its core role as an “architect of the immune microenvironment,” whereby it remodels T-cell immune responses through precise mechanisms to establish an immunosuppressive tumor microenvironment. Specifically, F. nucleatum employs virulence factors such as Fap2 and FadA for specific colonization, and achieves immune evasion by inhibiting NK and T-cell function and recruiting myeloid-derived suppressor cells (MDSCs). Post-colonization, it further fine-tunes T-cell subsets: driving Th17 polarization to create a pro-inflammatory milieu while suppressing the infiltration and function of CD8 + T cells and promoting their exhaustion. Intriguingly, it upregulates programmed death-ligand 1 (PD-L1) expression, which may conversely enhance tumor sensitivity to anti-PD-1/PD-L1 immunotherapy. Moreover, it collaborates with other microbes via quorum sensing and the oral-gut axis to construct a procarcinogenic ecosystem. Based on these mechanisms, F. nucleatum exhibits substantial clinical translational potential. Its load serves as an effective non-invasive diagnostic biomarker and a prognostic predictor, and may help predict responses to immune checkpoint inhibitors. Therapeutically, strategies targeting the eradication or inhibition of F. nucleatum —including antibiotics, specific phages, virulence factor inhibitors, and combination immunotherapy—represent highly promising novel directions. Despite existing challenges, future efforts to deepen mechanistic understanding, develop precision intervention tools, and establish integrated patient stratification systems hold the potential to revolutionize CRC prevention, diagnosis, and combination therapy by targeting F. nucleatum .

BACKGROUND: There is a dispute regarding the necessity of infrapyloric lymph node dissection in right hemicolectomy for hepatic flexure colon cancer. OBJECTIVE: To evaluate the risk factors for infrapyloric lymph node metastasis and the prognostic role of infrapyloric lymph node dissection in patients with hepatic flexure colon cancer and identify the population of patients who would benefit from infrapyloric lymph node dissection. DESIGN: Retrospective multicenter propensity score matching study to minimize heterogeneity between 2 groups. SETTINGS: This study was conducted at 3 medical centers. PATIENTS: A total of 531 patients who underwent curative resection for hepatic flexure colon cancer were included. MAIN OUTCOME MEASURES: The primary outcome measure was the metastasis rate of infrapyloric lymph nodes, whereas secondary outcome measure included overall survival. Logistic regression analysis was used to identify risk factors, and Kaplan-Meier analysis was used to evaluate survival outcomes. RESULTS: The metastasis rate of infrapyloric lymph nodes among patients undergoing infrapyloric lymph node dissection was 11.8% (26/221). Cox multivariate analysis confirmed that infrapyloric lymph node dissection was an independent prognostic factor after propensity score matching (HR 0.60; 95% CI, 0.38–0.84; p = 0.007). A proposed flowchart for infrapyloric lymph node dissection based on preoperative factors was created. Based on the proposed flowchart, patients with preoperative serum CEA level ≤5.0 ng/mL, cN+, and tumor size ≥5 cm and patients with preoperative serum CEA level >5.0 ng/mL were identified as the high-priority infrapyloric lymph node dissection group. The metastasis rate of infrapyloric lymph nodes in the high-priority group was 16.0% (20/125). In the high-priority group, patients undergoing infrapyloric lymph node dissection had better survival outcomes than those not undergoing infrapyloric lymph node dissection (p = 0.005). LIMITATIONS: This study is limited by its retrospective nature. CONCLUSIONS: This study suggests that infrapyloric lymph node dissection should be performed in specific patients with hepatic flexure colon cancer. See Video Abstract. EL VALOR DE LA DISECCIÓN DE LOS GANGLIOS LINFÁTICOS INFRA PILÓRICOS EN LA HEMICOLECTOMÍA DERECHA PARA EL CÁNCER DE COLON DEL ANGULO HEPÁTICO: UN ANÁLISIS MULTICÉNTRICO BASADO EN EL EMPAREJAMIENTO POR PUNTAJE DE PROPENSIÓN: ANTECEDENTES: Existe controversia sobre la necesidad de la disección de los ganglios linfáticos infra pilóricos en la hemicolectomía derecha por cáncer de colon del ángulo hepático. OBJETIVO: Evaluar los factores de riesgo de metástasis de los ganglios linfáticos infra pilóricos y el papel pronóstico de la disección de los ganglios linfáticos infra pilóricos en pacientes con cáncer de colon del ángulo hepático e identificar la población que se beneficiaría de la disección de los ganglios linfáticos infra pilóricos. DISEÑO: Estudio retrospectivo multicéntrico de emparejamiento por puntaje de propensión para minimizar la heterogeneidad entre dos grupos. AJUSTE: Estudio realizando en tres centros médicos. PACIENTES: Un total de 531 pacientes sometidos a una resección curativa por cáncer de colon del ángulo hepático. PRINCIPALES MEDIDAS DE RESULTADO: Se utilizó un análisis logístico para evaluar los factores de riesgo de metástasis de los ganglios linfáticos infra pilóricos y se utilizó el análisis de Kaplan-Meier para evaluar la supervivencia general. RESULTADOS: La tasa de metástasis de los ganglios linfáticos infra pilóricos entre los pacientes sometidos a disección de ganglios linfáticos infra pilóricos fue del 11,8 % (26/221). El análisis multivariable de Cox confirmó que la disección de ganglios linfáticos infra pilóricos era un factor pronóstico independiente después de la comparación por puntuación de propensión (cociente de riesgos instantáneos 0,60; IC del 95 %, 0,38 a 0,84; p = 0,007). Se creó un diagrama de flujo propuesto para la disección de ganglios linfáticos infra pilóricos basado en factores preoperatorios. Con base en el diagrama de flujo propuesto, los pacientes con un nivel de CEA sérico preoperatorio ≤5,0 ng/ml, cN+ y un tamaño tumoral ≥5 cm, y los pacientes con un nivel de CEA sérico preoperatorio >5,0 ng/ml se definieron como grupo de disección de ganglios linfáticos infra pilóricos de alta prioridad. La tasa de metástasis de los ganglios linfáticos infra pilóricos en el grupo de alta prioridad fue del 16,0 % (20/125). En el grupo de alta prioridad, los pacientes sometidos a disección de ganglios linfáticos infra pilóricos tuvieron mejores resultados de supervivencia que aquellos que no se sometieron a disección de ganglios linfáticos infra pilóricos (p = 0,005). LIMITACIONES: Estudio limitado por su naturaleza retrospectiva. CONCLUSIONES: El estudio sugiere que la disección de ganglios linfáticos infra pilóricos se debe realizar en pacientes específicos con cáncer de colon del ángulo hepático.
