Objective Extracapsular spread (ECS) and soft tissue deposits (STD) of squamous cell carcinoma (SCC) in the neck of patients with metastatic SCC of the upper aerodigestive tract have been shown to adversely affect actuarial and disease-free survival. No studies to date have detailed the distribution of ECS and STD within the neck. Material and Methods A total of 215 neck dissections from 155 patients were prospectively collected and analysed for the presence of both STD and ECS. As no classification for STD exists, their distribution was classified according to the nodal levels used for classification of cervical lymph nodes as described by the Memorial Sloan–Kettering Cancer Center. Results A total of 81 neck dissections from 59 patients were found to have either metastatic lymph nodes with ECS, STD or both. The distribution of lymph node metastasis, ECS and STD was very similar. Level II was most frequently affected, with Levels III and IV being affected less frequently. There were very few lymph node metastases to Level V, and this level contained no evidence of either ECS or STD. Conclusion The method of pathological assessment of neck dissection specimens and reporting on the presence of ECS and STD has not been formalized. By analysing neck dissection specimens in the manner described we can report on the presence or absence of ECS and STD with increased accuracy. This has considerable implications for patient management. |
