The critical role of patient follow-up after receiving a diagnosis of prostatic intraepithelial neoplasia.

Abstract

With the increasing incidence of prostatic intraepithelial neoplasia being found at the time of prostate biopsy and the association of prostatic intraepithelial neoplasia to coexisting prostate cancer and/or the future development of prostate cancer, patient compliance in following post-biopsy follow-up instructions for re-biopsy is becoming more significant in the detection of prostate cancer at an earlier and, therefore, potentially curable stage. During a 3-y period, we reviewed the charts of 130 patients who received an initial diagnosis of prostatic intraepithelial neoplasia after undergoing transrectal ultrasound of the prostate with biopsy. It is our policy to inform the patient of their diagnosis of prostatic intraepithelial neoplasia at the time of the initial biopsy and to recommend a repeat biopsy in 6-12 months. Patients are informed of the diagnosis of prostatic intraepithelial neoplasia verbally and in writing. In addition, a letter is sent to their referring physician with the re-biopsy recommendation. Thirty-nine of 130 patients (30%) were seen for re-biopsy within the specified time. An additional 36 patients (27.69%) were re-biopsied between 12 and 18 months after the initial diagnosis of prostatic intraepithelial neoplasia. An additional 11 patients (7%) were re-biopsied more than 18 months after their initial diagnosis. Forty-four patients failed to return for re-biopsy. Overall, patient follow-up within the desired protocol was poor and must be improved upon to prevent any delays in the diagnosis of prostate cancer.
