Pancreatic cancer, difficult to detect in the early stages and having incidence of recurring in the postoperative stage, has found an effective treatment in chemo-radiotherapy. Gemcitabine, an effective radio-sensitizer, has led to better results in patients suffering with this form of cancer, increasing survival with a clinical benefit. A study conducted by Pancreatic Diseases Branch of Kyushu University in Japan, using a schedule that infused gemcitabine twice weekly for patients suffering with locally advanced pancreatic cancer gave positive results on the survival rate and median survival time.
