Collectively, these advances are driving locally advanced rectal cancer management towards a "biologically-driven" and "function-preserving" model. Future efforts must focus on establishing standardized protocols for these technologies and validating their long-term benefits in survival and quality of life through high-quality, multi-center clinical trials.
We identified the risk factors for lung metastasis in LARC patients treated with nCRT and TME and developed a nomogram to facilitate individualized imaging and follow-up strategies. Further studies with larger sample size and external validation are warranted.
