Abbreviations: MRC = major reconstruction complication; PMPRT = postmastectomy proton radiation therapy.
Studies have varying definitions and terminology to describe MRC. We applied our definition of MRC to the data available in each study for the purpose of comparison. Studies also had varying inclusion criteria. This table includes courses of PMPRT where there was either implant, expander, or flap in place at the time of PMPRT delivery. It does not include patients who had radiation reconstruction complications before undergoing PMPRT or patients who had no reconstruction at the time of PMPRT.
