High-Grade Prostatic Intraepithelial Neoplasia
High-grade prostatic intraepithelial neoplasia (HGPIN) has been established as a precursor to prostatic adenocarcinoma. HGPIN shares many morphological, genetic, and molecular signatures with prostate cancer. Its predictive value for the development of future adenocarcinoma during the prostate-specific antigen screening era has decreased, mostly owing to the increase in prostate biopsy cores. N...
متن کاملFrequency of high-grade prostatic intraepithelial neoplasia in Mexican population.
BACKGROUND High-grade intraepithelial neoplasia (HGPIN) is the only lesion regarded as precursor of prostatic carcinoma, though its frequency is unknown in many countries. Here we studied the frequency of HGPIN in a population with high grade frequency of prostatic carcinoma. MATERIAL AND METHODS A total of 486 cases of sextant prostatic biopsies performed from January 2001 to January 2006 we...
متن کامل[Expression of nuclear Ki-67 antigen in prostatic high grade intraepithelial neoplasia and prostatic carcinoma].
BACKGROUND/AIM Prostatic intraepithelial high grade neoplasia (PINHG) is accepted as preneoplastic lesion in prostatic carcinoma. One of the fundamental events in early oncogenesis is the disruption of proliferative activity. One of the numerous regulatory proteins is Ki-67 expressed in all proliferating cells. Index Ki-67 is considered to have prognostic significance. The aim of the study was ...
متن کاملClinical features and prognosis of prostate cancer with high-grade prostatic intraepithelial neoplasia
PURPOSE To evaluate the clinical features and biochemical recurrence (BCR) in prostate cancer (PCa) with high-grade prostatic intraepithelial neoplasia (HGPIN). MATERIALS AND METHODS We retrospectively analyzed the medical records of 893 patients who underwent a radical prostatectomy for PCa between 2011 and 2012 at Asan Medical Center; 752 of these patients who did not receive neoadjuvant or...
متن کاملMicroinvasion of High-Grade Pancreatic Intraepithelial Neoplasia
High-grade pancreatic intraepithelial neoplasia (PanIN-3) is recognized as a precursor lesion of invasive ductal carcinoma (IDC). However, histological evidence that PanIN-3 invades beyond the basement membrane of pancreatic ductal epithelium, that is, the moment PanIN-3 becomes IDC, has not been captured yet. This may be because PanINs which are microscopic papillary or flat lesion rarely deve...
