Survival outcomes were analyzed using the Kaplan-Meier method. Factors were compared between groups using log-rank test and Fisher\u2019s exact test, and prognostic factors were screened using the Cox proportional hazards model. Propensity score matching (PSM) was conducted to examine the treatment differences after accounting for sex, age, race, T stage, N stage, and M stage.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Level I (57.1%) and level II (53.6%) nodes were the most common sites of lymph node metastasis, followed by level III (17.9%) and IV (17.9%) nodes.
