Invasive pancreatic ductal carcinoma is a representative refractory malignant tumor, and even with the development of early diagnosis and treatment techniques, the treatment outcome has been remarkably poor. Surgical resection is the curative treatment for resectable pancreatic cancer and borderline resectable pancreatic cancer. However, the survival rate in patients with pancreatic cancer treated by resection alone is low because of the high postoperative recurrence rate. In this review article, we report recent studies on perioperative treatment for pancreatic cancer. Perioperative therapy is the addition of chemotherapy or radiation therapy before or after surgery to improve resectability and curative effects. Because it is difficult to cure redsecttable pancreatic cancer by surgery alone, multidisciplinary treatment combined with perioperative adjuvant chemotherapy is the current standard of care. Although perioperative chemotherapy and chemoradiotherapy have been investigated for borderline resectable pancreatic cancer, the effectiveness of preoperative treatment has not been sufficiently proven. Potentially curative pancreatic cancer is treated by surgery plus perioperative therapy; treatment cannot be either alone. We regard the successful completion of surgery and perioperative care as the key to improving treatment outcomes. Therefore, ongoing randomized controlled trials for the treatment of BR-pancreatic cancer are expected to induce further improvements survival outcomes of patients with BR-pancreatic cancer.
