The labelling index in chronic nonspecific prostatitis ranges from 0.7-2.1%. This value is markedly higher than in nodular hyperplasia (0.4%) as well as in differentiated adenocarcinomas (0.6%). Increased labelling index could only be determined in glands adjacent to inflammatory foci. In recognition of these findings we believe that a correct evaluation of the cell proliferation in chronic prostatitis is only possible if each single cell can be evaluated, whether it is altered by inflammation or not. Therefore, solid tissue biopsies appear to be more suitable in autroadiographical studies than cytological material alone.
慢性非特异性前列腺炎的标记指数范围为0.7%-2.1%。该值明显高于结节性增生（0.4%）以及分化型腺癌（0.6%）。仅在炎症灶附近的腺体中可检测到标记指数升高。基于这些发现，我们认为只有对每个单细胞进行评估，无论其是否受到炎症影响，才能正确评估慢性前列腺炎中的细胞增殖情况。因此，在放射自显影研究中，实体组织活检似乎比单纯的细胞学材料更合适。
