Protons
• Proposed by Wilson in 1946 (Radiology, 1946)
• Years ’50: first patients treated in Uppsala and Berkeley (Sweet W RS, NEJM, 1951)
• Years ’70: first patients treated in Russia and Japan
• In 1990 the first clinical centre at Loma Linda University (CA)
• First hospital-based
proton-therapy centre
• First patient: 1992

Carbon Ions
• First patients treated in 1975 at Bevalac,
Berkeley, CA, even ion properties were
well know since the beginning of years ‘50
• 2000 patients treated with helium ions and 500 with neon ions in 20 years (Sweet W RS,
NEJM, 1951)
• Since 1994 in Japan the first patient treated with carbon ions

The potential benefit of radiotherapy with protons in head and neck
cancer with respect to normal tissue sparing: a systematic review of
literature
TA van de Water et al, The Oncologist, 2011, 16: 366-377
Groningen & Maastricht, The Netherlands
• 14 in silico planning comparative (ISPC) studies
• Protons have the potential for a significantly lower normal tissue dose,
while keeping similar or better target coverage
• Probability of reducing >25% salivary flow with IMRT
is 22% , and with IMPT 9%
• Probability of reducing grade 2-4 swallowing dysfunction
is reduced by 8.8% with IMRT, and by 17.2% with IMPT
The results of these ISPC studies should be confirmed in properly designed clinical trials
