School is in session! The Accelerators (Drs. Anna Brown, Matt Spraker, and Simul Parikh) sit down for a radiation oncologist and colorectal specialist Dr. Nina Sanford for an informal lesson on the state of radiotherapy for rectal cancer in 2023.  We work our way through an informal discussion of total neoadjuvant therapy, sequencing of therapies, radiotherapy techniques, and my favorite new #RadOnc concept, PULSAR. We close the show by peer reviewing Simul's case and discussing the finer points of rectal cancer contouring.Here are other some things we discussed during the show:We talked about a lot of rectal studies, just check out Rad Onc Tables GI TabTodd's Twitter poll on IMRT for rectal cancer Bob Timmerman's excellent editorial about his SBRT constraintsTzeng sarcoma study referenced for bowel constraintsThe Janus StudyWax Lips and Fun Dip CandyPodcast art generously donated by Dr. Danielle Cunningham.
