摘要

The impact of apical lymph node (ALN) status on the prognosis of colorectal cancer (CRC) remains controversial, and ALN status is not included in the current Tumor Node Metastasis (TNM) staging system. This study aimed to evaluate the effect of ALN status on recurrence and survival rates. In this retrospective study, 117 stage 3 CRC patients aged over 18 who underwent surgery between 2015 and 2024 and had their ALN status determined were evaluated. Patients with metastatic disease at diagnosis, those with undetermined ALN status, and those with concurrent malignancies were excluded. Patients were analyzed based on demographic, clinical, pathological, and survival data. The median age was 61 years (range: 33–83), and 60.7% of the patients were male. The pN stage was significantly more advanced (p < 0.001) and the number of metastatic lymph nodes was significantly higher (p = 0.003) in the ALN ( +) group. During a median follow-up of 46 months, 14 local recurrences, 31 systemic recurrences, and 27 cancer-related deaths were observed. Local recurrence, systemic recurrence, and cancer-related deaths were significantly more frequent in the ALN ( +) group (p = 0.027, p < 0.001, and p < 0.001, respectively). Locoregional disease-free survival, systemic disease-free survival and overall survival were significantly shorter in the ALN ( +) group (p = 0.011, p < 0.001, and p < 0.001, respectively). In multivariate analysis, SDFS and OS were found to be significantly shorter in the ALN ( +) and pN2 groups. ALN metastasis can be considered as an additional adverse prognostic factor in CRC beyond the pN stage.
