The indolent nature of pulmonary metastases from ductal adenocarcinoma of the pancreas.
摘要：
The natural history of pulmonary metastases from pancreatic ductal adenocarcinoma (PDAC) is not well studied. Limited evidence suggests patients with isolated pulmonary metastases from PDAC follow a more benign clinical course than those with other sites of metastases. We performed a retrospective review of all patients with pulmonary metastases from PDAC from 2000 to 2010 and analyzed survival utilizing the Kaplan-Meier method based upon location of first metastasis (lung first, intra-abdominal first, or synchronous intra-abdominal and lung metastases). Median survival among subjects with lung as the only site of metastases was significantly longer than those with other metastatic patterns. In subjects that had undergone resection of their PDAC, survival in those with lung as a first site of recurrence remained significantly longer than those with abdominal first or synchronous intra-abdominal and lung recurrence. Among resected patients that developed lung only recurrence, survival was significantly prolonged (67.5 months) in those who underwent surgical resection/stereotactic radiosurgery compared to chemotherapy (33.8 months) or observation (29.9 months) for treatment of lung recurrence. Patients with isolated pulmonary recurrence from PDAC may realize a survival benefit from surgical intervention or stereotactic radiosurgery compared to chemotherapy or observation for treatment of lung recurrence.
