Patients with stage A2 carcinoma of the prostate are a heterogeneous population and not all of them progress to clinically manifest disease. We found a similar variability in terms of the pathological findings in a group of 34 patients with stage A2 disease undergoing pelvic lymphadenectomy and radical prostatectomy. While 8 patients (24 per cent) had metastatic disease on staging lymphadenectomy, 9 patients (27 per cent) had negative lymphadenectomy, with minimal or no residual tumor in the radical specimen. The histologic grade and extent of tumor on transurethral resection did not predict reliably patients with stage A2 disease and minimally invasive cancer at radical prostatectomy. It appears that present criteria for separating stage A tumors into focal and diffuse categories are adequate for selecting therapy for patients with incidental carcinoma of the prostate.
A2期前列腺癌患者是一个异质性群体,并非所有患者都会进展为有临床症状的疾病。我们在一组34例接受盆腔淋巴结清扫术和根治性前列腺切除术的A2期疾病患者中,发现其病理结果存在类似的变异性。在分期淋巴结清扫术中,8例患者(24%)有转移性疾病,9例患者(27%)淋巴结清扫阴性,根治性标本中残留肿瘤极少或无残留肿瘤。经尿道前列腺切除术中肿瘤的组织学分级和范围并不能可靠地预测A2期疾病且在根治性前列腺切除术中为微浸润癌的患者。目前将A期肿瘤分为局灶性和弥漫性类别的标准似乎足以用于选择前列腺偶发癌患者的治疗方案。
