We studied 454 patients with prostatic adenocarcinoma who were assigned a preliminary clinical stage on the basis of serum acid phosphatase, routine bone survey and physical examination. Subsequently, they were assigned a final clinical stage after radioisotopic bone scanning, lymphangiography and staging pelvic lymph node dissection. Only 53, 54, 57 and 26 per cent, respectively, of patients initially assigned the preliminary clinical stage of IB, II, III or IVA remained at that stage after the additional studies.
我们研究了454例前列腺腺癌患者，这些患者根据血清酸性磷酸酶、常规骨扫描和体格检查被初步确定临床分期。随后，在进行放射性核素骨扫描、淋巴管造影和分期盆腔淋巴结清扫术后，确定其最终临床分期。最初被初步确定为IB、II、III或IVA期的患者，在进行额外检查后，分别仅有53%、54%、57%和26%的患者仍处于该阶段。
