Results generated by the immunohistochemical staining with PC10, a new monoclonal antibody recognizing PCNA (a nuclear protein associated with cell proliferation) in formalin-fixed and paraffin-embedded tissue were compared with those of Ki-67 labeling and DNA flow cytometry in 47 consecutive non-small cell lung cancer (NSCLC). PCNA reactivity was observed in all samples and confined to the nuclei of cancer cells. Its frequency ranged from 0 to 80% (37.7 +/- 23.6) and larger sized, early- staged and DNA aneuploid tumors expressed a significant higher number of PCNA-reactive cells. The PCNA and Ki-67 labeling rates were closely correlated (r = 0.383, P = 0.009). By flow cytometry, we observed a good correlation among PCNA labeling and S-phase fraction (r = 0.422, P = .0093) and G1 phase (r = 0.303, P = .051) of the cell cycle. Results indicate that PCNA labeling with PC10 is a simple method for assessing the proliferative activity in formalin-fixed, paraffin-embedded tissue of NSCLC and correlates well with Ki-67 labeling and S-phase fraction of the cell cycle.
