[Pancreatic cancer showing complete pathological response to preoperative chemoradiotherapy-a case report]

The patient was a 57-year-old man who was diagnosed as having stage IVa pancreatic cancer. We selected preoperative chemoradiation therapy( gemcitabine[ GEM] plus S-1; and radiation therapy[ RT], 50.4 Gy/28 Fr). A month later, distal pancreatectomy was performed after completion of the course of chemoradiation therapy. Histopathological examination revealed no cancer cells in the pancreas or the dissected lymph nodes. The pathological effect was judged as grade IV. The patient has had no recurrence for 8 months since pancreatectomy.
