Radiation Oncology for Dummies

On this episode of the SO files, Brad and Linda dive into the basics of radiation oncology, with the goal to give a basis of understanding for different radiation therapy regimens. The episode begins with an overview of what is radiation oncology and what are the major types of radiation oncology we should know about. For this episode, the SO files are excited to welcome on repeat guest Dr. Parag Parikh, Associate Professor of Radiation Oncology, and chief of GI radiation oncology at Washington University in St. Louis School of Medicine.

Recent Developments in Radiotherapy

Deborah E. Citrin

A recently published (September 2017) and well written review article in the NEJM , highlighting several forms of radiation oncology and the mechanisms behind them.

Stereotactic body radiation therapy for inoperable early stage lung cancer

Timmerman R, Paulus R, Galvin J, Michalski J, Straube W, Bradley J, Fakiris A, Bezjak A, Videtic G, Johnstone D, Fowler J, Gore E, Choy H.

Phase 2 RTOG 0236 trial of stereotactic body radiotherapy for cT1-2N0M0 medically inoperable NSCLC patients. Only 59 patients enrolled, with 55 evaluable, and median follow up 34.4 months. Estimated 3 year local control was 97.6%. 

Lobectomy versus stereotactic body radiotherapy in healthy patients with stage I lung cancer

Rosen JE, Salazar MC, Wang Z, Yu JB, Decker RH, Kim AW, Detterbeck FC, Boffa DJ.

Rosen and colleagues looked at the national cancer database for healthy patients that were surgical candidates with cT1-2N0 lung cancer. They found that patients undergoing lobectomy did better than those receiving stereotactic radiotherapy. They went on to propensity score match lobectomy and stereotactic body radiation therapy patients, with lobectomy conferring a 59% 5 year survival vs 29% for stereotactic radiotherapy.

Sorafenib Tosylate With or Without Stereotactic Body Radiation Therapy in Treating Patients With Liver Cancer

Ongoing phase III RCT comparing sorafenib + stereotactic body radiotherapy versus sorafenib alone for patients with hepatocellular carcinoma who are not suitable for surgery, transplant or radiofrequency ablation.
