Overestimation of contralateral hilar lymph node metastasis in non-metastatic non-small cell lung cancer and its predictive model: HAM

Metastasis of non-metastatic non-small cell lung cancer (NMNSCLC) to contralateral hilar lymph nodes (CHLN) eliminates the opportunity for radical therapy. This study aims to analyze whether CHLN metastasis in NMNSCLC is commonly overestimated in clinical practice and to establish a predictive model for enhanced precision.
