Abstract
BACKGROUND: There is no international consensus concerning the role of surgical treatment of metastatic pancreatic ductal adenocarcinoma (mPDAC), but favorable prognoses can be expected for highly selected patients. METHODS: A comprehensive literature search of the PubMed and Cochrane databases was conducted using combinations of keywords to 4 July 2018. Eligible studies were those reporting on patients with histologically confirmed mPDAC undergoing surgery with curative intent. We excluded case reports with fewer than five patients, insufficient descriptions of survival data, and palliative or cytoreductive surgery as well as studies that assessed para-aortic lymph node metastasis or peritoneal washing cytology. RESULTS: Thirteen studies were deemed eligible, and six studies were identified from their references. The studies involved 428 patients who underwent surgical resection for liver metastases (n = 343), lung metastases (n = 57), and peritoneal dissemination (n = 28). Median overall survival (OS) in patients with synchronous liver metastases who underwent conversion surgery following favorable response to initial chemotherapy was 27 or 34 months, and peritoneum metastases was 28 months. Median OS after the initial treatment was varied from 51 to 121 months in metachronous lung metastasis and from 24 to 40 months in metachronous liver metastasis, respectively. CONCLUSION: Encouraging OS was indicated in patients with synchronous mPDAC of liver and peritoneum who underwent conversion surgery. Metastasectomy for metachronous lung and liver oligometastases could be considered a practical treatment option.
