目的分析累及移行带前列腺癌的临床特征,提高移行带前列腺癌的诊断率。方法回顾我院收治的77例前列腺癌患者,一组44例仅限于外周带;另一组33例已累及移行带。分析两组的临床表现、直肠指检、移行指数、前列腺移行带特异性抗原密度、前列腺特异性抗原、经直肠前列腺超声以及前列腺穿刺活检。结果两组患者的年龄、排尿期和储尿期症状、直肠指检阳性率、移行指数、前列腺移行带特异性抗原密度、前列腺特异性抗原以及病理分级没有显著性差异。移行带肿瘤存在泌尿系转移的风险。经直肠超声为移行带可疑病灶的定位提供了重要的参考,而对可疑病灶穿刺活检则能提高累及移行带前列腺癌的诊断率。结论经直肠超声行移行带可疑病灶的穿刺活检是诊断累及移行带前列腺癌的有效手段。
Objective To analyze the clinical characteristics of transitional zone prostate cancer and to improve the diagnostic rate of transitional zone prostate cancer. Methods A retrospective study of 77 cases of prostate cancer admitted to our hospital, a group of 44 cases were limited to the peripheral zone; the other 33 cases had involved the transition zone. The clinical manifestations, digital rectal examination, transitional index, prostate specific antigen density, prostate specific antigen, transrectal ultrasound and prostate biopsy were analyzed. Results There were no significant differences in age, urinary and urinary symptoms, positive rate of digital rectal examination, migration index, prostate specific antigen density, prostate specific antigen and pathological grading. Migraines have the risk of urinary tract metastases. Transrectal ultrasound provides an important reference for the localization of suspicious lesions in transitional zone, while the biopsy of suspicious lesions can improve the diagnosis of prostate cancer involving transitional zone. Conclusion Transrectal ultrasonography is a useful diagnostic method for the diagnosis of prostate cancer with metastasis with transcranial biopsy.
