Abstract:
Objective:To investigate the expression of p16 and GATA3 and the detection of human papillomavirus (HPV) in secondary bladder involvement by cervical carcinomas.
Methods:Sixteen cases of cervical carcinoma with bladder involvement diagnosed from December 2008 to March 2016 were collected and evaluated by light microscopy, immunohistochemistry for p16 and GATA3 detection and PCR-reverse dot blot for molecular typing of HPV.
Results:The age of the patients ranged from 25 to 76 years with median of 52 years. Morphologically, 14 cases(14/16) showed tumor nests infiltrating lamina propria or muscle bundles of the bladder. By immunohistochemistry, 15 cases (15/16) were found to be diffusely and strongly positive for p16, and 1 showed patchy staining pattern. Seven cases (7/7) of corresponding original cervical cancers were also diffusely and strongly positive for p16. GATA3 staining was negative in 13 cases (13/16), and focal weak to moderate positivity was detected in 3 cases.Three cases (3/7) of corresponding original cervical cancers showed focal weak to moderate positivity of GATA3. Fifteen cases (15/16) showed concordant high risk HPV-positivity, including HPV16 in 8 cases and HPV31 in one case. Five cases showed co-infection of HPV16 and HPV18. One case showed co-infection with HPV18 and HPV45.
Conclusion:Differential diagnosis by p16 or GATA3 alone is of limited value. Combination of immunohistochemistry for p16 and GATA3 and molecular typing for HPV detection are useful to distinguish primary bladder carcinoma from the secondary involvement by cervical carcinoma.
