PCNA and laminin as prognostic factors in primary Fallopian tube carcinoma
open access
Abstract
70 cases of primary Fallopian tube carcinomas were analysed with regard to clinicopathological data, survival and the expression of proliferating cell nuclear antigen (PCNA) and laminin. Histological classification of PTFC revealed 26 cases of the endometriod type, 16 undifferentiated, 15 serous, 8 urothelial, 3 clearcell and 3 of other types. A total of 70 cases revealed positive nuclear staining for PCNA. The index of PCNA (labelling index, LI, proportion of PCNA-positive cells relative to all neoplastic cells) was evaluated. PCNA LI values were classified as high, > 0.45, or low, ≤ 0.45. Intracellular expression of laminin was found in 46 cases and extracellular in 28 cases. There was no significant correlation between the expression and distribution of laminin and survival. The p value was statistically significant only for PCNA LI as an independent prognostic factor.
