Key result
High dose radiotherapy (6000 cGy to tumor, 5777 cGy to pacemaker) achieved complete tumor remission without pacemaker malfunction at three months in an 85-year-old man with esophageal cancer.

Does high dose radiotherapy cause pacemaker malfunction in a patient with an implanted pacemaker?
High-dose radiotherapy (up to 5777 cGy) was successfully administered to a patient with a pacemaker without causing device malfunction, challenging the traditional 200 cGy limit.
Lai et al. (2013) conducted a case report in Esophageal cancer with cardiac pacemaker implantation (n=1). High dose radiotherapy was evaluated on Tumor remission and pacemaker malfunction. High dose radiotherapy (6000 cGy to tumor, 5777 cGy to pacemaker) achieved complete tumor remission without pacemaker malfunction at three months in an 85-year-old man with esophageal cancer.
