ABSTRACT

INTRODUCTION:

Papillary squamotransitional cell carcinoma (PSTCC) arising from the uterine cervix is a distinctive histomorphological subtype of squamous cell carcinoma (SCC) not otherwise specified (NOS) of cervical epithelial tumors.

AIM:

The present study was undertaken to study the histopathological features and immunoexpression of CK7, CK20, p53 and Ki-67 in PSTCC of the cervix. MATERIALS AND

METHODS:

This study included 43 cases of PSTCC of cervix. A technique of manual tissue array was employed along with IHC staining of entire section in some cases. The expression pattern of CK7, CK 20, p53 and Ki67 in PSTCC was studied and clinico-pathological correlation of various parameters with IHC expression of CK7 and CK20 was observed. Results were subjected to statistical analysis and were considered significant when the p-value was less than 0.05.

RESULTS:

Out of 43 PSTCC cases, there were 38 squamotransitional type and 5 papillary type. Histomorphologically, all the cases studied were having fused papillae with rounded contours and fibrovascular cores with highest number of cases having intermediate cell type morphology (86%). Stromal invasion was seen in 74.4% of cases. Koilocytosis were seen in 39.3% of cases. Thirty-two cases showed CK7 immunopositivity (+) and CK20 immunonegativity (-), nine cases were both CK7 and CK20 - and two cases were CK7- and CK20+. Among them 90.7% cases were p53 positive and all cases were positive for Ki67 immunostaining with highest number of cases showing moderate proliferative activity (74.4%); followed by nine cases showing high (20.93%) and two cases showing low proliferative activity (4.65%).

CONCLUSION:

The distinct histomorphology and CK7/CK20 immnunoprofile of PSTCC along with Ki67 and p53 could help in arriving at an accurate diagnosis as well predicting its biological behavior.
