中文摘要 | 背景:攝護腺癌侵犯到貯精囊表示預後較不好。本研究的目的是要評估侵犯貯精囊的徑路是淋巴血管或局部侵犯,如此或可以決定疾病的程度屬於全身性的還是僅止於局部。 方法:我們以回溯性研究的方式,對32位患局部攝護腺癌而接受攝護腺根除術的病患作臨床及病理學上的研究。 結果:在32位病患中,12位(37.5%)有貯精囊侵犯,其中7位為雙側,5位為單側。此12位病患全都是癌細胞從週邊的攝護腺組織侵入貯精囊的肌肉層。7位有雙側貯精囊侵犯的病患,其中 4位在手術後7至12個月發生骨轉移。而單側貯精囊侵犯的病患在手術後追蹤至39個月尚未發現有骨轉移。 結論:我們的結果顯示攝護腺癌侵犯貯精囊是經由局部的侵犯,雙側貯精囊侵犯似乎比單側貯精囊侵犯的病患有較高骨轉移的機率。此方面之探討,仍需有更多的病患及更進一步的研究才能闡明攝護腺癌侵犯貯精囊的路徑。 |
英文摘要 | Background: Adenocarcinoma of the prostate with seminal vesicle involvement indicates a rather poor prognosis. The aim of this study is to evaluate the route of seminal vesicle involvement via lymphaticovascular or local extension, as a possible way which may determine the extent of disease as systemic or local. Methods: In a retrospective study of 32 patients who underwent radical prostatectomy for localized cancer of the prostate, medical records and imaging studies were reviewed, and the histopathological slides of the resected specimens were rechecked. Results: Of 32 patients, 12 (37.5 %) had seminal vesicle involvement. Seven patients had involvement of bilateral seminal vesicles and five had unilateral involvement. Tumor cells invaded the muscle portion of seminal vesicle from the adjacent prostatic tissues in all 12 patients. Four of the seven patients with involvement of bilateral seminal vesicles developed bony metastasis 7 to 12 months after operation. No patient with unilateral involvement of seminal vesicle was found to have disease progression to bony metastasis during follow-up for as long as 39 months. Conclusions: The route of seminal vesicle involvement in prostate cancer was through local extension in all of our patients. Involvement of bilateral seminal vesicles may have more chances to develop bony metastasis than unilateral involvement. Further study with a large number of patients is necessary to clarify the issue regarding the route of seminal vesicle involvement in adenocarcinoma of prostate. |
