Long-term survival after repeated resection for lung metastasis originating from pancreatic cancer: a case report

Abstract

Abstract Background Pancreatic cancer has a grave prognosis. Most patients with metastatic pancreatic cancer are inoperable, and case reports of resection of lung metastasis from pancreatic cancer are rare. This patient underwent resection of a lung metastasis twice after pancreaticoduodenectomy for pancreatic cancer. Case presentation A 75-year-old man with pancreaticoduodenectomy and adjuvant chemotherapy for pancreatic cancer was diagnosed with a lung metastasis 48 months after surgery. Histological findings after thoracoscopic partial resection of the right lung by video-assisted thoracic surgery confirmed the presence of a lung metastasis originating from the pancreatic cancer. The patient refused chemotherapy. A new lung metastasis was detected 84 months following the second surgery (132 months after the pancreaticoduodenectomy). After thoracoscopic partial resection of the left lung by video-assisted thoracic surgery, the histological findings once again confirmed a metastasis that originated from the pancreatic cancer. The patient refused chemotherapy and remained alive and relapse-free after the 10-month follow-up. Conclusion Detection and resection of an isolated lung metastasis originating from pancreatic cancer may improve prognosis. Careful follow-up may be warranted to identify patients who might benefit from aggressive local treatment of oligometastasic pancreatic cancer.
