Background:
In this study, we aimed to determine the correlation between supraclavicular lymph node involvement (SLNI) and metastatic potential, frequency, and metastases predilection sites in patients diagnosed with various head and neck tumors (HNT) and staged via positron emission tomography/computed tomography (PET/CT) imaging. We also investigated the impact of different variables on SLNI.
Patients And Methods:
270 patients diagnosed with HNT were enrolled in the study (194 males and 96 females, mean age 54.9 ± 14.7 years (range 18-89 years)).
Results:
Nasopharyngeal carcinoma demonstrated significant SLNI (p < 0.01); however, other subtypes of HNT did not. In all HNT studied, no apparent metastatic predilection tendency for the supraclavicular region was observed, as opposed to the well-described Virchow's node. Age, gender, tumor size, and systemic metastases were not identified as statistically significant variables contributing to SLNI. Multivariate regression analysis revealed an increased cervical (p < 0.01) and thoracic (p = 0.001) lymph node involvement in patients with SLNI.
Conclusion:
SLNI with the possibility of metastasis was more frequently observed in nasopharyngeal carcinoma, advancing the nodal status without significantly influencing the T and M stages. A careful evaluation of this very small region is of critical importance for proper nodal staging in nasopharyngeal cancer patients.

The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen.

The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
