正如肝内转移的肝细胞癌,原发脏器内转移的原发癌是其肿瘤临床病理分期中的一个重要特征。胰腺导管癌(PDC)胰腺内转移(P-ⅠM)能偶尔遇到,但尚未见研究报道。本研究的目的是探讨PDC患者中P-ⅠM的临床病理特点和预后价值。该作者回顾性研究了日本东京国立癌症中心医院2003年至2010年间393例PDC胰腺切除标本的病理组织学特征。P-IM被定义为具有与原发肿瘤相似的病理组织学特征的独立性肿瘤。在所复习的患者中有21例(5.3%)发现了26个P-IM。P-IM
Just as intrahepatic metastasis of hepatocellular carcinoma, primary cancer metastasized within the primary organ is an important feature of its clinical and pathological staging. Pancreatic ductal (PDC) pancreatic metastasis (P-I M) can be encountered occasionally, but has not been reported. The purpose of this study was to investigate the clinicopathological features and prognostic value of P-ⅠM in patients with PDC. The authors retrospectively reviewed the histopathological features of 393 patients with pancreatic pancreatectomy from 2003 to 2010 at the National Cancer Center Hospital in Tokyo, Japan. P-IM is defined as a separate tumor with similar histopathological features as the primary tumor. Twenty-six P-IMs were found in 21 (5.3%) of the patients reviewed. P-IM
