On N ovember 8, 1895, in his laboratory in Wurzburg, W. C. R oentgen(Figure 1) registered the new type of penetrating rays. H e spent sevenweeks to follow working on his experiment and on D ecember 26, 1895,took the very first picture of his wife’s hand with a ring using what hecalled the new rays, creating the new famous roentgen picture.For this revolutionary discovery he was awarded with first nble prize in physics in 1901.
It was already on January 12, 1896, only 17 days from publishingRoentgen’s discovery, that E mil G rubbe applied X-rays to irradiatea female patient suffering from locally advanced breast cancer andrecorded palliative effect. He himself died in 1960 as the result of multiple squamouscarcinomas with metastases probably due to his work with radiation.
Despeignes was the first to apply roentgen therapy inFrance. In July 1896 he treated a case of gastric carcinomawith 80 sessions lasting between 15 and 30 min daily. Hereported improvement and pain relief. Treatment was giventwice daily
In Austria, the dermatologist LeopoldFreund had among others observed epilation after exposureto x-rays. In 1896 he treated a patient with hairynevus (3) daily over 2 weeks and was the first to givefractionated radiotherapy
The field grew rapidly through the last years of the 19thcentury and into the first years of the 20th (3). Antoine-HenriBecquerel, a physics professor in Paris, was the first to recognizenatural radioactivity while working with uranium salts
The first cases of basal cellcarcinoma of the skin and squamous cell carcinoma of theskin were cured in Stockholm in 1900 by T. Stenbeck andT. Sjogren (4), who used the same technique as Freund
The depth towhich X-rays can penetrate into biological tissue is related to thephoton energies, and therefore, early radiotherapy was verylimited by devices that could produce only low X-ray energies(f100 keV). Stimulated by the early successes of X-ray therapy,many scientists turned their attention to producing higher energyX-rays that penetrate deeper into tissue. This was necessary toreduce dose deposition in skin, thus allowing for treatment ofinternal tumors without causing severe skin burns at pointswhere beams enter the body.By 1913 William Coolidge, an American physicist, was workingwith General Electric to develop hot-cathode X-ray tubes, whichproduced energies in the 200 keV range. Treatment with thesetubes was initially termed deep roentgen therapy and later calledorthovoltage XRT
One of the oldest rules in radiobiology —developed in 1906 by two French radiobiologists,Bergonié and Tribondeau — offereda prediction about the relative sensitivity ofdifferent types of cells to radiation. The socalled‘Law of Bergonié and Tribondeau’concluded that cells tend to be radiosensitiveif they have three properties: a highdivision rate, a long dividing future, and anunspecialized phenotype22. This law pavedthe way for several radiobiology rules thatwere discovered a few years later by Germanand British radiation scientists from in vitro experiments.
In 1911 Claudius Regaud, an intern from Lyon, showed that aram’s testes could be sterilized without causing major burns tothe scrotal skin, if three irradiations were delivered 15 days apart(11, 12). This series of landmark experiments established the basisof what would become the principle of fractionation for externalbeam radiotherapy (XRT
In the 1920s, Coutardapplied the concept of fractionated XRT with treatment coursesprotracted over several weeks. Using this strategy, he was able tocure patients with a variety of head and neck malignancies and topopularize this concept of fractionation in the internationalcommunity (2, 13–15). His technologic advancesincluded many concepts taken for granted today, including customimmobilization of patients, beam hardening with metallic filters toachieve higher photon energies, and collimation/shaping of beams.
in 1955 by Thomlinson and Gray whenthey proposed that oxygen levels decreasedin a respiring tumour mass through eachsuccessive cell layer distal to the lumen ofthe capillary.
