The problem is magnified in prostatic cancer because of its wide range of cell types, growth patterns and degrees of anaplasia. 182 cases of prostatic cancer from 1480 cases of prostatic biopsy specimens were analyzed according to the differentiation of prostatic cancer and three grades were recommended. 25 cases (13.7%) were well differentiated, 59 cases (32. 4%)were moderately differentiated and 98 cases (53. 8%) were poorly differentiated (including undifferentiated cases).The differential diagnosis of well differentiated type cancer from hyperplasia is the most difficult problem and the characteristic features of cancerous glands are based on (1) uniform glands, (2)monolayered cells, (3) loss of saw -like lumen, and (4) predominant nucleoli.

There were 6 cases (4.6%) whose PSA were<4ng/ml, 16 cases (12.3%) PSA 4~10ng/ml, 108 cases (83.1%) PSA>10ng/ml. In the patients whose PSA<20ng/ml, 4 cases already were detected with bone metastasis, but in those with PSA>40ng/ml, 46 cases had bone metastasis. Of 108 cases of prostatic biopsy, 101 (93.5%) were positive. The detective rate of transrectal ultrasound screening was 94.7%, transabdominal ultrasound screening 55.1%, CT、MR 42.9%, ECT 81.3%. 95 cases (75.3%) were stage of C and D and 35 cases (24.7%) were stage A and B.Conclusion Early detection of prostatic cancer is still a question to be solved. Propagating knowledge of prostatic di sease, seeking medical advice and examined by specialist timely after 50 years of age might increase early diagnostic rate.(Shanghai Med J, 1999,22∶515 517)

Objective:This study was to assess the changes after prostatic biopsy and the effect of these changes on the magnetic resonance imaging of prostate cancer.Methods:102 patients with biopsy-proved prostate cancer were divided into two groups according to the time interval between biopsy and imaging:group A(less than 3 weeks)and group B(3 weeks to 1 year).The findings on MR imaging were compared between the two groups and the diagnostic accuracy was studied together with the pathological findings.Results:Postbiopsy hemorrhage was detected 51.4%(18/35) in group A and 14.9%(10/67) in group B(P0.01).Comparing with the pathologic results,the diagnostic accuracy of MR was 91.4% in group A and 94.2% in group B with no statistical significance.However,there was significant difference of the false positive rate between the two groups(P0.05).Conclusions:Postbiopsy hemorrhage is easy to form within the initial 3 weeks after the biopsy,with a result of increased false positive rate.MR examination is recommended to execute 3 weeks delay or prior to the biopsy.

目的 :评价前列腺癌穿刺活检后的MR表现及其对MR诊断准确性的影响。方法 :将 10 2例活检证实的前列腺癌患者分为两组 ,A组为活检后 3周内行MR检查者 ,B组为活检后 3周到 1年内行MR检查者。对两组患者的MR表现进行分析 ,并和穿刺病理结果对照 ,研究了MR诊断的准确性。结果 :A组中有 5 1.4% (18/ 35 )出现活检后血肿 ,B组中有 14 .9% (10 / 6 7)出现血肿及其后遗改变 (P 0 .0 1)。和穿刺活检的病理结果对照 ,A组患者MR诊断准确率为 91.4% ,假阳性率为 2 0 .5 % ;B组患者MR诊断准确率为 94.2 % ,假阳性率为 11.4%。两组之间诊断准确率没有显著差异 ,但假阳性率有显著性差异 (P 0 .0 5 )。结论 :前列腺活检后 3周内易出现血肿 ,使MR诊断的假阳性率增高。对前列腺癌的MRI检查应于活检 3周以后或活检之前进行。
