Abstract
Abstract Aims To assess nodal harvest quality and adjuvant chemotherapy utilisation after colorectal cancer resection in a contemporary surgical cohort. Methods All resections performed in MDT-discussed colorectal cancer patients between April 2024 and April 2025 were reviewed. Lymph node yield (“nodes examined”), nodal positivity (“nodes involved”), and adjuvant chemotherapy use were analysed. Descriptive statistics were used, with subgroup comparison by urgency where available. Results Ninety-two patients underwent resection in a district general hospital (2024-2025). Nodal yield was recorded in 83 cases, with a median of 20 nodes examined (IQR 15–26.5). A threshold of ≥12 nodes was achieved in 65/83 (78.3%). Nodal positivity data were available in 82 resections, 29/82 (35.4%) had ≥1 positive node. Among node-positive resections, adjuvant chemotherapy was recorded in 19/29 (65.5%) compared with 8/53 (15.1%) node-negative resections. Median nodal yield was higher in elective than emergency surgery (20 vs 16.5 nodes; data available in 67 elective and 14 emergency cases). Conclusions This cohort demonstrates a strong median nodal harvest with most resections meeting the ≥12-node benchmark, but a notable minority fall below target. Adjuvant chemotherapy use was appropriately higher in node-positive disease. Targeted audit of low-yield specimens and standardised pathology reporting may further strengthen oncological quality and treatment consistency.
