Conclusion
This study presents that T cells may interact with NK cells and
macrophages through PD-1 and PD-L1 to promote pLN metastasis of CC. In
addition, we construct an immune nomogram that incorporates five items
of PD-1, PD-L1, the average distance of CD56 to PD-1, the average
distance of CD56 to PD-L1, and the average distance of PD-1 to PD-L1,
which can be conveniently used to facilitate the preoperative
individualized prediction of pLN metastasis in patients with CC.
