Carbon Ions Boost Followed by Pelvic Photon Radiotherapy for High Risk Prostate Cancer
This trial is active, not recruiting.
|Condition||adenocarcinoma of prostate|
|Treatment||carbon ions boost followed by pelvic photon radiotherapy|
|Sponsor||European Institute of Oncology|
|Collaborator||Associazione Italiana per la Ricerca sul Cancro|
|Start date||May 2015|
|End date||December 2015|
|Trial size||65 participants|
|Trial identifier||NCT02672449, IEO 98|
The aim of this research project is to test the feasibility and safety of a new treatment schedule for high risk prostate cancer that allows the administration of high doses to the prostate tumor with a mixed beam approach of carbon ions boost followed by pelvic IMRT.
|Endpoint classification||safety/efficacy study|

|Description||The present research project aims to improve the current treatment for high risk prostate cancer, evaluating the safety and feasibility of a new RT scheme of a carbon ions boost followed by pelvic photon RT. A total of 65 consecutive patients will be enrolled in a prospective phase II trial. The patients will be enrolled either at Centro Nazionale di Adroterapia Oncologica (CNAO), Pavia, Italy, at the Division of Radiation Oncology of the European Institute of Oncology (IEO), Milan, Italy, or at the Fondazione IRCCS Istituto Nazionale Tumori (INT), Milan, Italy. The treatment will include a boost phase on the whole prostate with carbon ions performed at CNAO followed by a pelvic photon IMRT performed with conventional fractionation of 1.8 Gy per fraction up to 45 Gy to the pelvic lymph nodes, prostate and seminal vesicles. All the patient data will be collected in a common database accessible from the 3 Institutions. At CNAO, carbon ions beam is available for patient treatment since 2011. In comparison to the Japanese Center NIRS, the facility relies on active beam delivery using the rasterscan technique, which offers not only physical advantages with better sparing of normal tissues in the entrance channel, but also enables biologic plan optimization. The facility has the same equipment as the Carbon Ion Treatment Center in Heidelberg, Germany. At CNAO, 3D - 4D patient target localization is verified at each fraction by integrating orthogonal X-ray images and 3D real time optical tracking system. At IEO and INT, the IMRT phase will be performed with the same treatment modality: volumetric-IMRT RapidArc by Varian Trilogy (IEO) and Varian DHX (INT) linacs, Varian Medical Systems, Palo Alto, CA, USA, with treatment based on the isocentric beam delivery, and pre-treatment image guidance for patient alignment via cone beam CT or portal imaging. In phantom, quality assurance (QA) of each treatment will be performed before patient RT, in order to verify the consistency between calculated and delivered dose.|
