Fewer Complications, Side-Effects for Esophageal Cancer Patients
Because most esophageal cancers are in close proximity to many critical organs, the need to reduce exposure to surrounding, healthy tissue is a major treatment consideration. A number of clinical and modeling studies have demonstrated that proton therapy may be safer than, and equally effective as, more conventional radiation in certain scenarios:
Locally advanced, unresectable esophageal cancer
- Can be applied in higher doses with less cardiac and pulmonary toxicities 
- Demonstrates favorable cancer control rates using dose escalated proton therapy [2-5]
Resectable esophageal cancer with neoadjuvant therapy
- Reduces radiation exposure to the heart, lung, and liver 
- Results in lower rates of post-operative, cardiac, gastrointestinal, and wound complications as compared to conventional radiation
- Produces fewer side-effects including less nausea and adverse hematologic reactions 
Recurrent esophageal cancer
- Can re-irradiate with acceptable cancer control rates and safety
