OA04.2. Single Cell Transcriptomic and T-Cell Receptor Diversity Analysis of Peripheral Blood Lymphocytes Comparing Proton Versus Photon-Based Chemoradiation in Esophageal Cancer
Abstract Topic Esophageal Cancer: Oncology/Radiation Therapy Background Radiation-induced lymphopenia (RIL) is a common toxicity during and after chemoradiation (CRT) but can be significantly mitigated with proton therapy (PT). The objective of this study is to determine if quantitative sparing of lymphocytes could also result in qualitative improvements in lymphocytes after CRT with PT compared to photons in esophageal cancer patients. Methods Patients were prospectively enrolled for longitudinal blood collection …
