| dc.description.abstract | ABSTRACT Background Fusions of transmembrane protease, serine 2 (TMPRSS2) with erythroblast transformation specific transcription factors have been found in prostate cancer. The v-etserythroblastosis virus E26 oncogene homologue (ERG) is a proto-oncogene of the erythroblast transformation specific transcription factor family. TMPRSS2-ERG fusion is the most common molecular alteration present in about 50% of prostatic adenocarcinomas. Androgen receptor (AR) plays a key role in prostate development and is involved in the progression of prostate cancer. Objective To evaluate the significance of combined ERG and AR expression in cases of prostatic adenocarcinoma. Method The study was conducted at Dr. Ram Manohar Lohia Institute of Medical Sciences, Lucknow, Uttar Pradesh, India. Formalin fixed-paraffin embedded archival prostatic tissue specimens were obtained. A total of 10 cases of prostatic adenocarcinoma were included in the study. Immunohistochemistry for Androgen receptor was done by the standard protocol. Multiplex immunohistochemical staining was done for ERG+CK5 using a primary antibody cocktail of mouse and rabbit antibodies. Result Specific AR immunostaining was exclusively nuclear and was present in all 10 cases in varying intensity. Specific ERG immunostaining was nuclear and was present in seven cases (70%) and absent in three cases (30%). The three cases that were negative for ERG had a Gleason score of ≤ 6 and the AR staining was strong and present in about 90% of the cells. Gleason score was directly related to the ERG staining while AR staining was inversely related to the ERG staining. Conclusion The prognostic value of combined ERG and AR over-expression, its associated genes should be further investigated as potential therapeutic targets in prostate cancer progression. Preliminary data is being presented. Larger prospective studies with survival analysis are essential for prognostic significance.
