Pancreatic metastases are rare, with a reported incidence varying from 1.6% to 11% in autopsy studies of patients with advanced malignancy. In clinical series, the frequency of pancreatic metastases ranges from 2% to 5% of all pancreatic malignant tumors. However, the pancreas is an elective site for metastases from carcinoma of the kidney and this peculiarity has been reported by several studies. The epidemiology, clinical presentation, and treatment of pancreatic metastases from renal cell carcinoma are known from single-institution case reports and literature reviews. There is currently very limited experience with the surgical resection of isolated pancreatic metastasis, and the role of surgery in the management of these patients has not been clearly defined. In fact, for many years pancreatic resections were associated with high rates of morbidity and mortality, and metastatic disease to the pancreas was considered to be a terminal-stage condition. More recently, a significant reduction in the operative risk following major pancreatic surgery has been demonstrated, thus extending the indication for these operations to patients with metastatic disease.
胰腺转移瘤很少见,尸检研究报告的发病率在晚期恶性肿瘤患者中为 1.6%至 11%。在临床系列中,胰腺转移瘤的频率范围为所有胰腺恶性肿瘤的 2%至 5%。然而,肾脏的癌是胰腺转移的首选部位,这一特点已被几项研究报道。肾细胞癌胰腺转移的流行病学、临床表现和治疗是从单一机构的病例报告和文献综述中了解到的。目前对于孤立性胰腺转移瘤的手术切除经验非常有限,手术在这些患者的管理中的作用尚未明确界定。事实上,多年来胰腺切除术与高发病率和死亡率相关,胰腺转移被认为是终末期疾病。最近,主要胰腺手术后的手术风险显著降低,从而将这些手术的适应证扩展到转移性疾病患者。
