 note = {In Japan, we have experienced the particle therapy for more than 30 years. The Japan Clinical Study Group of Particle Therapy (JCPT) studied the achievements of the Japanese particle therapy from 1979 to 2011. The study group covered the all particle therapy institutions. The aim of the paper is to disclose the status of Japanese particle therapy and to analyze the change of the number of the therapy.
The number of particle therapy treatment from 1979 to 2011 reached 18,269. Each annual number of particle therapy was 520 (244 proton:p, 276 carbon:c) in 2002, 794 (474 p, 320 c) in 2003, 1082 (699 p, 383 c) in 2004, 1276 (803 p, 473 c) in 2005, 1453 (827 p, 626 c) in 2006, 1712 (923 p, 789 c) in 2007, 1712 (781 p, 931 c) in 2008, 2233 (1278 p, 955 c) in 2009, 2469 (1421p, 1048c) in 2010 and 2884 (1757p, 1127c) in 2011.
The number of patients according to the primary lesion ranged 452 (347 p, 105 c) for CNS tumors, 2568 (1419 p, 1149 c) for Head and Neck tumors, 2093 (1172 p, 921 c) for lung tumors, 613 (524 p, 89 c) for upper digestive organ tumors, 2833 (2012 p, 821 c) for liver tumors, 519 (328 p, 191 c) for pancreas tumors, 305 (113 p, 192 c) for gynecological tumors, 4689 (3013 p, 1676 c) for prostate tumors, 1313 (311 p, 1002 c) for bone and soft tissue tumors, 483 (142 p, 341 c) for recurrent rectal tumors and 2386 (793 p, 1593 c) for other or unclassified tumors. The major target was a prostate cancer.
This paper reports the activity of Japanese particle therapy for 33 years. We think that the analysis of the particle therapy is very important for the radiation oncology. We will be able to realize the desirable co-operation between the JCPT hospitals and establish the Japanese database concerned with the proton and carbon ion therapy., ASTRO's 54th Annual Meeting},
