BACKGROUND AND OBJECTIVES:
there are few published data on the use of EUS guided fine-needle aspiration in secondary pancreatic lesions. We describe the largest series published so far in a European country.
PATIENTS AND METHODS:
a retrospective review of the cases identified in our institution from 2004 to 2016 has been recorded. The clinical data are described, comparing the latency period from the primary tumor diagnosis to the detection of the pancreatic metastasis and the survival of patients according to the cytological diagnosis.
forty-four patients were diagnosed with pancreatic metastasis using EUS guided fine needle aspiration. Ancillary cytological studies were performed in 28 (63.6%). The most common primary tumor sites were kidney and lung. Thirty-four patients (77.3%) had a previous history of malignancy, with a latency period ranging from 6 months to 18.8 years. Patients diagnosed with primary renal carcinoma had a significantly longer latency period and longer survival compared to those with primary lung cancer. In 13 patients, EUS was either the only technique that detected the PM or showed a greater number of intrapancreatic lesions. These metastases were significantly smaller than those diagnosed by other imaging studies (11.9 ± 4.1 mm vs 30.7 ± 19.8 mm, p < 0.001).
EUS guided fine-needle aspiration plays a crucial role in the diagnosis of pancreatic metastases and may have a major clinical impact. Patients with renal cell carcinoma could benefit from long-term follow-up with EUS.
