NGFR and neoplasm: A study by Søland et al. (2008) was conducted to evaluate the prognostic significance of p75NTR and the expression of p75NTR in 53 paraffin-embedded archival tissues of OSCC for the first time, both at the invasive front and in the rest of the tumour tissue and reported that p75(NTR) was expressed in all OSCCs, and p75NTR expression and the pattern of invasion were significantly associated with poor prognosis in OSCC [139].
