Retrospective Evaluation of the Last 10 Years Development of Particle (Proton, Carbon) Radiotherapy Centers

INTRODUCTION: The aim of this study is to evaluate the extent, development, capacity and future status of the particle treatment in the world and the change in the number of patients and particle treatment centers treated in the last 10 years. In addition, in our study, it is aimed to contribute to the establishment, planning and determination of the need for particle radiotherapy systems that are not currently available in our country where the latest technology and current methods in cancer treatment are applied.
METHODS: In the study, the centers using particle radiotherapy systems worldwide; information on the dates of installation, number of treatment rooms, installation process, planning stage and number of patients treated were reached. The data of these centers between 2010 and 2020 were evaluated retrospectively based on the center, number of treatment rooms and number of patients treated, rates.
RESULTS: While there were 9 countries in the world with a particle treatment system in 2010, this figure increased to 19 countries in 2020. When particle radiotherapy centers are included, the number of centers will increase to 25 countries, while carbon radiotherapy systems will increase to 8 countries. When we look at the number of treatment centers in 2010, there are 31 centers in total; 26 of them are protons, 3 of them are carbon and 2 of them are proton+ carbon. In 2020, these numbers have increased to 96 centers, of which 83 are proton, 7 are carbon and 6 are proton+ carbon treatment centers. When we consider the centers in the planning stage, it will increase to 161 centers in total. While the number of patients treated with particle radiotherapy was 76,266 in 2010, this figure reached 221,528 in 2018. The number of new patients treated annually per treatment room is in the range of 86-197 new patients/years in Proton and in the range of 28-211 new patients/years in carbon therapy.
DISCUSSION AND CONCLUSION: Thanks to the developments in the health sector, our country has become the reference hospitals and centers of our region. Considering the situation in the world and the situation our country is in, it is seen that in order for this feature to continue, our country should switch to carbon therapy in addition to proton therapy.

Parçacýk (Proton, Karbon) Radyoterapi Merkezlerinin Son 10 yýllýk Geliþiminin Retrospektif Deðerlendirmesi

GÝRÝÞ ve AMAÇ: Parçacýk tedavisinin dünyada yaygýnlýðý, geliþimi, kapasitesi ve gelecekteki durumu ile tedavi edilen hasta ve parçacýk tedavi merkez sayýlarýnýn son 10 yýllýk dönemde deðiþiminin deðerlendirilmesi amaçlanmýþtýr. Ayrýca çalýþmamýzda kanser tedavisinde en son teknoloji ve güncel yöntemler uygulanan ülkemizde þu anda bulunmayan parçacýk radyoterapi sistemlerin kurulumu, planlanmasý ve ihtiyacýn belirlenmesine katký saðlanmasý da amaçlanmýþtýr.
YÖNTEM ve GEREÇLER: Çalýþmada, dünya genelinde parçacýk radyoterapi sistemlerini kullanan merkezlerin; kurulum tarihleri, tedavi oda sayýlarý, kurulum süreci, planlama aþamasý ve tedavi edilen hasta sayýlarýna yönelik bilgilerine ulaþýldý. Bu merkezlerin 2010 – 2020 yýllarý arasýndaki verileri merkez, tedavi oda sayýsý ve tedavi edilen hasta sayýlarý ve yýl bazlý oranlarý retrospektif olarak deðerlendirilmiþtir.
BULGULAR: Dünyada parçacýk tedavi sistemine sahip 2010 yýlýnda 9 ülke varken 2020 yýlýnda bu rakam 19 ülkeye çýkmýþtýr. Ýnþaatý devam eden parçacýk radyoterapi merkezleri ile birlikte 25 ülkeye, karbon radyoterapi sisteminde 8 ülkeye çýkacaðý görülmektedir.
Tedavi merkez sayýlarý yönünden baktýðýmýzda 2010 yýlýnda toplamda 31 merkez olup bunun; 26 tanesi proton, 3 tanesi karbon ve 2 tanesi proton+karbon iken 2020 yýlýnda bu rakamlar toplamda 96 merkeze çýkmýþ olup bunun da 83 tanesi proton, 7 tanesi karbon ve 6 tanesi proton+ karbon tedavi merkezidir. Planlama aþamasýndaki merkezleri de dikkate aldýðýmýzda toplamda 161 merkeze çýkacaktýr.
Parçacýk radyoterapisi ile tedavi olan hasta sayýlarý 2010 yýlýnda 76.266 iken 2018 yýlýnda bu rakam 221.528'lere ulaþmýþtýr. Tedavi odasý baþý yýllýk tedavi edilen yeni hasta sayýlarý protonda 86-197 yeni hasta/yýl aralýðýnda olup karbon tedavisinde 28-211 yeni hasta/yýl aralýðýndadýr.

TARTIÞMA ve SONUÇ: Özellikle saðlýk sektöründeki geliþmeler sayesinde ülkemiz bölgemizin referans hastaneleri ve merkezleri konumuna gelmiþtir. Dünyadaki durum ve ülkemizin içinde bulunduðu durum düþünüldüðünde bu özelliðimizinin devam edebilmesi için ülkemizin proton tedavisi yaný sýra karbon tedavisine de geçmesi gerektiði görülmektedir
