How did my colon cancer radiation treatment restart go after abscess delay?

Dons update scan. DIAGNOSIS: Don O Vanvoltenberg is a 58 y.o. male with adenocarcinoma of the colon. Treatment originally initiated 12/22/2025 - 1/6/2025 (held due to abscess requiring drainage). He now re-initiates EBRT course following a re-planning of radiotherapy target volume. He underwent verification simulation on the Varian Edge treatment system prior to receiving his first radiation treatment of this updated radiotherapy treatment plan. untitled image 3 partial coplanar VMAT-IMRT arcs. 6 MV photon beam energy. untitled image untitled image DESCRIPTION: Today he was taken into the Varian treatment room and placed in the supine position, arms elevated. A wing board was used for upper body immobilization. A customized vac-lok device was used for his lower body immobilization (styrofoam block between distal lower extremities and tied). He was first aligned in the appropriate treatment position utilizing his skin markings and the in-room laser system. Cone beam-CT imaging was then obtained with adjustments made for anatomic localization. I personally reviewed the treatment setup as well as the cone beam -CT images as compared with the patient's reference CT scan obtained at initial simulation. Once appropriate treatment positioning was verified, the verification simulation concluded. He tolerated the procedure well without any complications. He then underwent his first radiation treatment utilizing 6 MV photons via VMAT-IMRT (3 partial arcs) technique with multileaf collimation. Hadi Zahra, MD 3:37 PM
