Prostate cancer is incidentally diagnosed in 6%-11% of benign prostatic hyperplasia surgeries.
A 79-year-old man was diagnosed with benign prostatic hyperplasia. The prostate volume was 54.5 mL, and the prostate-specific antigen level was 7.121 ng/mL. Magnetic resonance imaging and prostate biopsy were not performed. He then underwent contact laser vaporization of the prostate. After 3 months, gross hematuria occurred, and the prostate-specific antigen level was 62.495 ng/mL. Cystoscopy and magnetic resonance imaging revealed prostate cancer with bladder invasion. Prostate biopsy and transurethral resection were performed, revealing adenocarcinoma with a Gleason score of 5 + 5. The patient was diagnosed with prostate cancer T4N1M1b, and triplet therapy was initiated. After 6 months, the prostate-specific antigen level was 0.037 ng/mL, and the metastases had shrunk.
Vaporization for high-grade prostate cancer can lead to rapid progression. Therefore, screening for prostate cancer before benign prostatic hyperplasia surgery is important.
在6% - 11%的良性前列腺增生手术中会偶然诊断出前列腺癌。
一名79岁男性被诊断为良性前列腺增生。前列腺体积为54.5毫升，前列腺特异性抗原水平为7.121纳克/毫升。未进行磁共振成像和前列腺活检。随后他接受了前列腺接触式激光汽化术。3个月后，出现肉眼血尿，前列腺特异性抗原水平为62.495纳克/毫升。膀胱镜检查和磁共振成像显示前列腺癌侵犯膀胱。进行了前列腺活检和经尿道切除术，结果显示为 Gleason 评分5 + 5的腺癌。该患者被诊断为前列腺癌T4N1M1b，并开始进行三联疗法。6个月后，前列腺特异性抗原水平为0.037纳克/毫升，转移灶缩小。
高级别前列腺癌的汽化术可导致疾病快速进展。因此，在良性前列腺增生手术前筛查前列腺癌很重要。
