Abstract

Background: Breast cancer ranks first among cancer in urban population of India, and 2nd most common in the rural population. Proliferative activity acts as an adjunct and gives prognostic importance in breast cancer. However, the best method for measurement of proliferative rate is controversial. The aim was to evaluate the association between PCNA labeling index (PCNA-LI) and Ki67 labeling index (Ki67-LI) and their correlation with histological grade.

Methods: Seventy cases of simple and modified Radical Mastectomy specimens with the diagnosis of carcinoma breast were included in the study. H&E stained sections were examined for assessment of histological grade. IHC scoring was done for the markers Ki-67 and PCNA. Correlation of PCNA with Ki67 and tumor grade was performed.

Result: 18 specimens were grade 1 tumors, 36 cases were grade 2 and 16 were grade 3. 90.0% of tumors were positive for PCNA index and Ki-67 positivity was observed in 85.7% cases, median and mean values of PCNA and Ki67 were 52.0, 51.64+/-37.475, and 24.50, 26.17± 24.183 respectively. Final score was divided into low and high index using median value as a cut off. Ki-67 LI showed strong positive correlation with histological grade (p=0.0001). PCNA LI showed positive correlation with histological grade (p=0.041) but no correlation was observed with Ki-67 LI (p=0.232)

Conclusion:  PCNA marker cannot substitute Ki67 but may be used as an additional marker to assess proliferative activity along with other markers. It may be useful to categorize subgroups with different grades of proliferative activity due to its easy applicability and assessment techniques.
