While the authors of the second publication suggested that proton therapy for inoperable pancreatic cancer was associated with a high rate of gastric and duodenal ulceration, a subsequent criticism of this study[17] pointed out that the severe toxicity exhibited was more likely due to the extremely aggressive radiotherapy dose offered with full-dose gemcitabine rather than any toxicity unique to proton therapy. Finally, while some institutions have advocated preoperative X-ray-based radiotherapy for patients with marginally resectable or resectable disease, many surgeons are reluctant to operate on previously irradiated patients, citing concerns about radiotherapy toxicities complicating what is already a complicated operation. The group from Massachusetts General Hospital completed a phase 1 study of preoperative short-course chemoradiation confirming the safety of a preoperative dose of 25 Gy (RBE) in 5 fractions over 1 wk with concomitant oral capecitabine at 825 mg/m twice a day, Monday through Friday, for 10 d followed by surgery.

In most cases, surgery is the first method of treatment of pancreatic cancer to be considered. In theory, proton therapy may be more effective and produce fewer side effects than photon radiation therapy, but theres still not enough data to support this hypothesis. Perhaps the biggest advantage of proton therapy for pancreatic cancer is that it can help treat large tumors without destroying healthy cells, compared with other treatment options, such as traditional radiation therapy or chemotherapy. Obesity can increase your risk of developing pancreatitis. Ding et al[11] compared passively scattered and modulated scanning proton therapy to a number of X-ray-based strategies including 3D conformal radiation therapy (3DCRT), 5-field IMRT, and 2-arc volumetric modulated radiation therapy.
