Answer

Answer

Preoperative XRT:

  • Benefits of using preoperative therapy are that large tumors adjacent to critical organs may become resectable; a smaller treatment field is needed; and potentially less tumor seeding may occur during resection

  • The common dose for XRT is 50 Gy

  • Negative aspects of using this therapy include increased wound-healing complications [7, 8]

  • If margins are close (< 1 cm) or positive, consider boost with brachytherapy, intraoperative radiation therapy (IORT), or postoperative XRT/intensity modulated radiation therapy (IMRT) at doses ranging from 10-26 GY [9]
