Abstract
- from our study we found that clinically suspicious intraoperative central lymph node is a significant factor predicting lateral cervical LNM and clinical decision of surgeon is very crucial and important. Also pathologically proven metastatic central lymph nodes carried significant risk for LLNM. - Risk factors like age, male gender, pathological capsular invasion, ETE, LVI, size of tumor nodule despite being non-significant predicting LLNM in the univariate analysis of our study, perhaps due to the small sample size and single-center limitations, a stronger evidence in the literature shown their significance. - Level II lymph node should not be ignored if lateral lymph node dissection is decided, as it was frequently involved with metastatic lymph nodes. - The prophylactic procedure changed the risk stratification in majority of our cases which changed RAI dose given to those patients. - TNM staging not accurate for decision making of postoperative RAI as it’s more broad staging, instead, ATA 2015 risk stratification more accurate as it depends on number and size of metastatic lymph nodes.
