Abstract:
Objective To investigate the clinical and pathological features of prostate cancer with low level of serum prostate-specific antigen (PSA) in elderly patients.Methods Data of 328 patients with prostate cancer were retrospectively analyzed.Clinical and pathological data of 4 prostate cancer patients with low serum PSA level were analyzed.Potential risk factors and diagnostic methods of prostate cancer with low serum PSA level were discussed based on the clinical data combined with literatures.Results Mean age of the 4 patients was 71.3 years.Mean PSA value on admission was 1.96 μg/L.2 patients had abnormal digital anal examination results.2 patients were pathologically diagnosed as adenocarcinoma after puncture,among which 1 had duct adenocarcinoma,and the other 2 patients were pathologically diagnosed as neuroendocrine carcinoma after puncture.2 patients with neuroendocrine carcinoma of prostate were treated with endocrine therapy,and the other 2 patients were treated with radical prostatectomy plus auxiliary endocrine therapy.Conclusions Prostate cancer with low serum PSA level has an insidious onset,which is prone to miss the diagnosis.It should be paid sufficient attention for the diagnosis,and monitoring of prostate cancer is independent on PSA.Prostate cancer with low serum PSA level should be diagnosed in combination with some basic examinations such as serum free prostate specific antigen,prostate specific antigen density and digital rectal examination,et al.
