High-risk pathological features at the time of salvage surgery predict poor survival after definitive therapy in patients with head and neck squamous cell carcinoma.

ABSTRACT:

Objectives

Salvage surgical resection is the preferred treatment for head and neck squamous cell carcinoma (HNSCC) patients who develop locally recurrent disease after failing primary therapy. However, salvage surgical resection is not always feasible, and survival outcomes for those that do undergo salvage remain poor. It is well known that patients with adverse pathological features (extracapsular extension (ECE) of lymph nodes (LN), positive margins, perineural invasion (PNI), lymphovascular invasion (LVI), and multiple LN metastases) at the time of primary surgical resection are likely to have relatively poor outcomes. However, the impact of adverse pathological features on outcomes in the salvage setting remains controversial.
