Risk of carotid blowout after reirradiation with particle therapy

Purpose Carotid blowout (CB) is a serious complication in retreatment of neoplasms in the head and neck (H&N) region. Rates seem to increase in hypofractionated or accelerated hyperfractionated regimens. In this study, we investigate the CB rate and the cumulative doses received by the carotid artery (CA) in a cohort of patients who were reirradiated at CNAO with particle therapy in the H&N reg...

Proton Therapy of eye using MCNPX code

Introduction: Proton radiotherapy is the one of advanced teletherapy methods. The protons deposit their maximum energy in a position called Bragg peak. Therefore, for treatment of cancer, the tumor should be placed at the Bragg peak or SOBP. The scattered photons and neutrons is a challenge in proton radiotherapy. The aim of this study is calculation of absorbed dose from scatt...

Proton beam therapy for medulloblastoma.

It is heartening to read a report of good functional outcomes following proton beam therapy in young patients with medulloblastoma, including the absence of many unpleasant side eff ects that can occur after conventional photon therapy. The authors quote UK research, which criticises the current proton therapy treatment policy of dividing the x-ray (photon) equivalent dose by 1·1. This is done ...

Proton therapy for hepatocellular carcinoma.

Proton radiotherapy has seen an increasing role in the treatment of hepatocellular carcinoma (HCC). Historically, external beam radiotherapy has played a very limited role in HCC due to a high incidence of toxicity to surrounding normal structures. The ability to deliver a high dose of radiation to the tumor is a key factor in improving outcomes in HCC. Advances in photon radiotherapy have impr...
