Reports on lung resection for recurrence with lung metastases after the surgical treatment of pancreatic cancer have been sporadic, and limited information is currently available on the long-term postoperative course. Furthermore, the significance of the surgical resection of recurrent/metastatic lesions after the resection of pancreatic cancer has not been sufficiently established. We herein present a long-term recurrence-free survivor after perioperative chemotherapy and pancreatic resection for primary pancreatic body cancer who underwent resection for isolated lung metastases twice.
A 66-year-old woman with locally advanced pancreatic cancer accompanied by invasion of the splenic artery underwent distal pancreatectomy with celiac axis resection following preoperative S1 + gemcitabine therapy. Recurrence with lung metastasis was detected 42 and 62 months after resection of the primary lesion, and lung resection was performed both times. As postoperative adjuvant therapies, S1 + gemcitabine therapy was performed after lung resection. The patient has survived free of recurrence for 11 years after resection of the primary lesion and 5 years and 9 months after the second lung resection.
A long interval from resection of the primary lesion to the occurrence of lung metastases and the high responsiveness of the patient to chemotherapy may have contributed to her long-term survival.
This case suggests that if lung metastasis occurring after radical resection of the primary lesion is resected without remnants, aggressive multidisciplinary treatment, including surgical resection with the appropriate selection of cases, may contribute to improvements in patient outcomes.
