Conclusion
We evaluated the predictive value of LODDS in patients with advanced HPSCC, and LODDS ≥ -0.91 was correlated with poorer DFS (p<0.001). We compared the predictive value of both ratios (LNR and LODDS) and pN for OS and DFS and did not find a greater predictive effect of LODDS over LNR and pN. Meanwhile, LNR provided a greater predictive value than pN and LODDS in predicting DFS.
