ABSTRACT
Objective To investigate the clinicopathological features and immunohistochemical expression of P504s,E-cadherin,erythroblast transformation-specific related gene(ERG)and estrogen receptor(ER)in prostate adenocarcinoma in Tibet.Methods The clinical data of 15 patients with prostate adenocarcinoma diagnosed by the Department of Pathology of Tibet Autonomous Region People's Hospital from September 2013 to September 2020 were analyzed retrospectively.All patients were assigned to prognostic grade groups based on Gleason score according to the WHO 2016 criteria.Immunostaining of P504s,E-cadherin,ERG,and ER was performed.Results The age of all 15 patients ranged from 61 to 86 years.The serum prostate specific antigen(PSA)concentration was ≥20 ng/ml in 12 patients and<20 ng/ml in 3 patients.Among the 15 patients,11 underwent needle biopsy,1 transurethral resection of the prostate,and 3 radical prostatectomy.Prognostic grouping results revealed 5 cases in grade groups 1-3,4 cases in grade group 4,and 6 cases in grade group 5.Immunohistochemistrically,15 cases(100%)were positive for P504s,E-cadherin and PSA;one case(7%)was positive for ERG;all cases were negative for P63,ER and CK34βE12.Thirteen cases were followed up for 2-48 months,with 2 cases treated with total prostatectomy and 11 cases with non-surgical treatment.Two cases were lost to follow-up. Conclusions Prostate adenocarcinoma is rare relatively in Tibet.The accuracy of diagnosis can be improved by using multiple immunohistochemical markers.The cases of grades 4 and 5 by pathological confirmed are relatively common in Tibet.P504s and E-cadherin are highly expressed in prostate adenocarcinoma patients in Tibet,while ERG presents low expression,ER is unexpressed.
