On 40 consecutive patients with prostatic cancer who had pedal lymphangiography during the initial evaluation and, subsequently, underwent pelvic node dissection or biopsy, a surprisingly high number had falsely positive (59 per cent) or negative (36 per cent) x-ray findings. Initially the tumors were considered clinically to be stage B in 24 cases, stage C in 13 and stage D in 3. After lymph node dissection only 17 tumors were still considered to be stage B and 7 were stage C, while 16 tumors were actually stage D. This surgical staging is important for the further management of the patient as well as the prognosis, Pedal lymphangiogrpahy alone is unreliable for accurate assessment of the regional lymph node status in clinically localized prostatic cancer.
对40例在初始评估时接受足部淋巴管造影、随后接受盆腔淋巴结清扫或活检的前列腺癌患者进行研究，结果发现，X线检查结果出现假阳性（59%）或假阴性（36%）的人数出奇地多。最初，24例肿瘤临床诊断为B期，13例为C期，3例为D期。淋巴结清扫术后，只有17例肿瘤仍被认为是B期，7例为C期，而实际上有16例肿瘤为D期。这种手术分期对患者的进一步治疗和预后都很重要。仅足部淋巴管造影对于准确评估临床局限性前列腺癌的区域淋巴结状态并不可靠。
