Abstract: 根治的前立腺全摘除術を施行した前立腺導管癌の1例を報告する。病理学的病期(pT3bN1)は術前の臨床パラメータ(cT1cN0,PSA7.64ng/ml)に基づく予測よりも進行していた。主病変の導管型腺癌は移行領域を占拠し, その周囲に通常型腺癌の小病変が散在していた。また導管型腺癌細胞と通常型腺癌細胞とが隣接して同一腺管の中に共存する部位も認められた。リンパ節転移部位には導管型腺癌細胞のみが認められた。さらに両型の腺癌細胞においてPSA蛋白の強発現とp63蛋白の消失がみられることを免疫組織化学的に確認した。前立腺導管癌を通常型腺癌と区別する臨床的意義について考察した。(著者抄録)
We report a case of prostatic duct adenocarcinoma treated with radical prostatectomy. Advanced pathological stage (pT3bpN1) was beyond the prediction of the favorable preoperative parameters (cT1cN0, PSA 7.64 ng/ml). The main tumor of ductal adenocarcinoma was occupying the transitional zone and surrounded by scattered micro-foci of acinar adenocarcinoma. We identified coexistence of ductal and acinar adenocarcinoma cells side by side in the same gland. Pure ductal cancer cells were detected in the metastasized lymph node without acinar cancer cells. Strong staining of PSA and loss of p63 expression by both types of adenocarcinoma cells were confirmed immunohistochemically. We discuss the clinical significance of prostatic duct adenocarcinoma in comparision with typical acinar adenocarcinoma.
