Park M, Park S, Kim E et al. Conversely, involvement of the contralateral lateral and specifically the infrabrachiocephalic upper mediastinal compartment indicates advanced, usually systemic disease.5 Lymphatic tumor cell dissemination conceivably progresses via posterior central lymph nodes in the paraesophageal area to ipsilateral lateral lymph nodes, or alternatively via direct lymphatic channels to the lateral jugular chain, as noted in upper thyroid pole primaries.29, The more lymph nodes are involved, the greater are the odds that one of the lymph node metastases happens to breach its nodal capsules to invade adjoining soft tissues.26 Quantitative assessment of lymph node metastases, in increments of 110 (N1), 1120 (N2), and >20 (N3) involved lymph nodes, is an important prognostic classifier. According to Tang Q (2), who reviewed the literature from 1979 to 2021, the most common origins of metastasis in these patients were renal cell carcinoma (48.1%), colorectal cancer (10.4%), lung cancer (8.3%), breast cancer (7.8%) and sarcoma (4.0%).
