From July 1, 1989 to June 30, 1990, 432 cases of transrectal prostatic ultrasound were done at San Pablo Hospital. Low density lesions were found in 85 patients in the peripheral zone. Twenty of these 85 cases proved to be malignant for an incidence of 23%. Our experience from January 1, 1988 to June 1989 was published previously. At that time, of a total of 486 cases, 72 patients showed low density lesion in the peripheral zone. Thirty-seven of these proved malignant for an incidence of 51.4%. To our original publication we are adding our recent 85 cases with 20 malignant lesions for a total of 157 cases of low density lesions and a total of 57 malignant lesions. We now have an average incidence of 36.3% malignancies in low density peripheral lesions.
1989年7月1日至1990年6月30日期间，圣巴勃罗医院共进行了432例经直肠前列腺超声检查。在外周区发现85例低密度病变患者。这85例中有20例被证实为恶性，发生率为23%。我们1988年1月1日至1989年6月的经验已在之前发表。当时，在总共486例病例中，72例患者在外周区显示低密度病变。其中37例被证实为恶性，发生率为51.4%。在我们原来的出版物基础上，我们增加了最近的85例病例，其中有20例恶性病变，总共157例低密度病变，57例恶性病变。现在我们在外周低密度病变中的恶性肿瘤平均发生率为36.3%。
