Background: The role of TNFalpha in cancer is complex with both pro-tumourigenic and anti-tumourigenic roles proposed. We hypothesised that anatomical microlocalisation is critical for its function.
Methods: This study used immunohistochemistry to investigate the expression of TNFalpha in the tumour islets and stroma with respect to survival in 133 patients with surgically resected NSCLC.
Results: TNFalpha expression was increased in the tumour islets of patients with above median survival (AMS) compared to those with below median survival (BMS)(p = 0.006), but similar in the stroma of both groups. Increasing tumour islet TNFalpha density was a favorable independent prognostic indicator (p = 0.048) while stromal TNFalpha density was an independent predictor of reduced survival (p = 0.007). Patients with high TNFalpha expression (upper tertile) had a significantly higher 5-year survival compared to patients in the lower tertile (43% versus 22%, p = 0.01). In patients with AMS, 100% of TNFalpha+ cells were macrophages and mast cells, compared to only 28% in the islets and 50% in the stroma of BMS patients (p < 0.001).
Conclusions: The expression of TNFalpha in the tumour islets of patients with NSCLC is associated with improved survival suggesting a role in the host anti-tumour immunological response. The expression of TNFalpha by macrophages and mast cells is critical for this relationship.
