Deep learning method for prediction of patient-specific dose distribution in breast cancer

Radiation Oncology, 2021
Background Patient-specific dose prediction improves the efficiency and quality of radiation treatment planning and reduces the time required to find the optimal plan. In this study, a patient-specific dose prediction model was developed for a left-sided

Long-term survival after definitive proton beam therapy for oligorecurrent esophageal squamous cell carcinoma: a case report

Journal of Medical Case Reports, 2022
Background Radical esophagectomy for esophageal squamous cell carcinoma has improved survival, but the rate of recurrence is high. Patients of recurrent esophageal squamous cell carcinoma after failure of chemotherapy have a poor prognosis.

Factors associated with overall survival, progression-free survival and toxicity in patients with small cell lung cancer and thoracic irradiation in a clinical real-world setting

Radiation Oncology, 2023
Background Small-cell lung cancer (SCLC) is a malignant tumor known for its poor prognosis. In addition to chemotherapy and immunotherapy irradiation plays a big role especially in inoperability.
