Backgrounds:
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 2002 to 2014.
The JCPT member consisted of the twelve particle therapy institutions;
(1) Southern Tohoku Proton Therapy Center, (2) Proton Medical Research
Center, University of Tsukuba, (3) Gunma University Heavy Ion Medical
Center (4) Division of Radiation Oncology and Particle therapy, National
Cancer
Center Hospital East, (5) Research Center for Charged Particle Therapy,
National Institute of Radiological Sciences, (6) Proton Therapy
Division, Shizuoka Cancer Center Hospital, (7) The Wakasa Wan Energy
Research Center, (8) Fukui prefectural Hospital Proton Therapy Center,
(9) Nagoya Proton Therapy Center, Nagoya City West Medical Center, (10)
Hyogo Ion Beam Medical center, (11) Ion Beam Therapy Center, SAGA HIMAT
Foundation and (12) Medipolis Proton Therapy and Research Center. Our
study group covered the all Japanese particle therapy institutions.
The aim of this paper is to develop the clinical database concerning
with Japanese particle therapy and to evaluate the feasibility of
particle therapy case database.
\nMethods:
The JCPT office gathered each institution’s annual report and analyzed
the number of treatments. Malignant primary tumors were classified into
CNS, head and neck, lung, upper digestive organ, liver, pancreas,
gynecological organ, prostate, bone and soft tissue, rectum and other or
unclassified organs. Particle therapy was divided into a proton therapy
and a carbon ion therapy.
At 2012 we decided that we should develop the clinical particle therapy
database for more precise analysis. We prepared the hardware and
software of the clinical database. Participating institutions send
records of cases after anonymization (Fig. 1). JCPT office handled each
data in secure and safety environment. The office prepared a suitable
conversion method from each hospital format to standard format.
\nResults:
The number of particle therapy treatment from 1979 to 2012 reached
21,506. Numbers of patients treated by proton and carbon ion are 12,150
and 9,356 showed in Fig.2. We defined the schema of database. This
schema consists of (1) patient informations including primary lesion,
stage, performance status, treatment purpose and (2) follow-up
information including primary effect, recurrence and secondary effect.
Many institutions cannot adapt to this schema of database. Some hospital
database systems do not contain the suitable fields corresponding to the
JCPT database fields. We found that the collecting method from a
proprietary database to the common database needs more consideration.
\nConclusions:
We reported the activity of Japanese particle therapy for more than 30
years. Moreover 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 clinical database related to the proton and carbon ion therapy., PTCOG53rd(Annual Conference of the Particle Therapy Co-Operative Group)においてポスター発表を行う},
