Further, we did not detect a significant association between the specific subtypes of lung cancer (non-small cell and small cell lung cancer) or breast cancer (luminal, human epidermal growth factor receptor 2 and triple negative) and 5-ALA fluorescence in the peritumoral brain tissue, tumor cell infiltration or angiogenesis (p = 1.000, respectively). Here, ERBB2 is linked to non-small cell lung carcinoma.
