The Johns Hopkins Proton Therapy center is establishing a registry to capture the full 3D radiation dosimetry delivered to the patient, baseline clinical data, and disease, toxicity and quality of life outcomes. The goal is to have all patients treated at the proton center to be included in the registry to enable future comparisons of treatment outcomes to assist in understanding which patients can benefit from the use of protons.

Proton based radiation therapy has considerable dosimetric advantages over the standard photon based radiation therapy, with a significantly higher cost. The clinical advantages, however, may not be realized for all patient populations, even with the improved dose distributions. Establishing the clinical efficacy of proton therapy requires years of experience treating patients. The goal is to accelerate the knowledge gain through the use of the registry that allows for detailed information to be captured and is inclusive of every patient treated.

Inclusion Criteria:

• All patients treated at the proton center.

Exclusion Criteria:

• Any other than what is supplied in the inclusion criteria

cancer patients with proton therapy
