Diagnosis of small prostate cancer foci is a real challenge for pathologists and urologists as it carries the risk of false positive or negative diagnosis with clinical consequences. Diagnosis of small prostate cancer foci requires a strict methodological approach which includes a search for major and minor features under low and high magnification. Ambiguous cases can be further clarified with the use of basal cell immunomarkers complemented by a positive indicator of malignancy. Despite the new diagnostic armamentarium, a few cases will continue to remain doubtful and might require an appropriate rebiopsy.
诊断小前列腺癌病灶对病理学家和泌尿科医生来说是一项真正的挑战,因为这存在假阳性或假阴性诊断的风险,并会产生临床后果。诊断小前列腺癌病灶需要一种严格的方法,包括在低倍和高倍放大下寻找主要和次要特征。对于不明确的病例,可以使用基底细胞免疫标记物并辅以恶性肿瘤阳性指标来进一步明确。尽管有新的诊断手段,但仍有一些病例会继续存在疑问,可能需要进行适当的再次活检。
