CHRNA7 and neoplasm: A granular cytoplasmic and apical membranous accumulation of CHRNA7 in tumor cells was observed in 25 out of 34 analyzed pancreatic specimens with a heterogeneous distribution pattern (10–40% of tumor cells), independent of the clinico-pathological parameters, including N (p = 0.672), M (p = 0.376), G (p = 0.971) status, smoking (p = 0.684) or survival (HR = 1.287; 95% CI = 0.58–2.83, p = 0.532).
