Phase I/II trial evaluating concurrent carbon-ion radiotherapy plus chemotherapy for salvage treatment of locally recurrent nasopharyngeal carcinoma

Chinese Journal of Cancer, 2016
Background After definitive chemoradiotherapy for non-metastatic nasopharyngeal carcinoma (NPC), more than 10% of patients will experience a local recurrence. Salvage treatments present significant challenges for locally recurrent NPC.

Improving total bone marrow and lymphoid irradiation: feasibility of intensity-modulated proton therapy (IMPT) and dosimetric comparison with helical tomotherapy (HT)

Radiation Oncology
Background and purpose This study aims to develop and validate a novel whole-body intensity-modulated proton therapy (IMPT) approach for total marrow/lymphatic irradiation (TMI/TMLI) and compare its efficacy to helical tomotherapy (HT).

Comparative clinical evaluation of atlas and deep-learning-based auto-segmentation of organ structures in liver cancer

Radiation Oncology, 2019
Background Accurate and standardized descriptions of organs at risk (OARs) are essential in radiation therapy for treatment planning and evaluation. Traditionally, physicians have contoured patient images manually, which, is time-consuming and subject to

Relativistic proton-proton scattering

Nuclear Physics B, 1968
Abstract In this paper we study elastic p-p scattering in the low-energy range. Relativistic off-shell integral equations for the T -matrix are derived from relativistic scattering theory and a technique for obtaining solutions is discussed explicitly. A field theoretic potential is constructed within the framework of one-boson-exchange model.

Proton-Proton Scattering at 340 Mev

Physical Review, 1950
Measurements of the proton-proton differential scattering cross section using 340-Mev protons show a cross section approximately constant between 41\ifmmode^\circ\else\textdegree\fi{} and 90\ifmmode^\circ\else\textdegree\fi{} in the center of mass system. Two methods of counting the scattered protons have been used.

Temporal dynamics of lymphocytes in prostate cancer patients treated with proton therapy

Frontiers in Oncology
Radiotherapy can be both immunosuppressive and immunostimulatory. Radiation-induced lymphopenia (RIL) is an ongoing challenge in cancer treatment.
