TUMOR ANTIGENS IN PROSTATE CANCER STRESSFUL COMMUNICATIVE PROBLEMS OF MODERN MAN.

This study investigated the immunohistochemical expression of the cancer testis antigen SSX in prostate cancer. SSX expression, with varying staining intensities, was observed in 83% of cancer samples. Substantial heterogeneity of expression was observed within individual samples. SSX expression was significantly higher in Gleason score 7 than in Gleason score 6 cancer (p=0.008). Tumours demonstrating capsular invasion had higher SSX expression than did tumours without capsular invasion (p=0.005). SSX expression did not correlate significantly with prostatespecific antigen level or tumour size. Further studies are needed to investigate SSX expression in prostate cancer and its potential implications for diagnosis and immunotherapy. [ABSTRACT FROM AUTHOR]
