In chemoradiotherapy (or radiotherapy) for the unresectable local progress non-small cell lung cancer, it is extremely important to suppress the onset of the radiation pneumonitis after the treatment.In a prediction of the radiation pneumonitis V20 (ratio of lung irradiated more than 20 Gy) and MLD (mean lung dose;)
It is said that an evaluation of mean pulmonary dosage) is important.However, current V20 is calculated based on anatomical embryonate, and the lung function is not added.
Therefore, as for us, radiation treatment planning using the lung function image usually examines the effect that the existing lung gives as compared with the treatment plan using the CT image.Generally, we weigh V20, the MLD which we perform the CT (we apply cerebral blood stream volume xenon CT that is insurance adaptation to the ventilation measurement of the lung) image which we make a lung function image made except the low-attenuation foci in a performed CT image and cold xenon inhaled and imaged, radiation treatment planning for each and calculated.In addition, we weigh it against V20, the MLD by false lung ventilation image obtained from anatomical CT image and the 4D-CT image.We arrive at Functional DVH (dose volume histogram) (functional dosage volume histogram) which is a new radiotherapy general idea after having examined a utility of the technique to evaluate a local lung function pictorially, and it is a purpose to demand a radiation pneumonitis predictor after the radiotherapy.
