In a patient with gastroesophageal adenocarcinoma treated with neoadjuvant chemoimmunotherapy who had a good response but is unable to undergo surgery, how would you approach radiation therapy?
What doses and dose constraints would you utilize?
Answer from: Radiation Oncologist at Academic Institution
As the ARTDECO study did not show a difference in local control between 50.4 Gy and 61.6 Gy (given with carbo/taxol, but FOLFOX is also an option per PRODIGE5, depending on chemotherapy used as part of the initial chemo-IO), I would suggest 50.4 Gy.
