With regard to RT, irradiated volumes, radiation doses, treatment failures, second-line treatment and survival were documented.
With radiotherapy techniques dramatically changing the dose and volume of radiation for so many sites of radiotherapy, the applicability of the outcomes from the large epidemiologic studies of earlier decades utilizing outdated techniques to the modern context is unclear.
Positron emission tomography (PET) may be useful for defining the gross tumour volume for radiation treatment planning and for response monitoring of non-small cell lung cancer (NSCLC) patients.
Therefore, daily water consumption volume distinguishes radiation injury alone from combined injury and, so, might be a good indicator for prognosis.
In some instances, the effectiveness of radiotherapy is reduced as there can be difficulties positioning obese patients and adjusting the volume of radiation needed for treatment 114– 114.
The prescribed dose for reirradiation was based on tumour volume, prior radiation dose, time since EBRT, and location of the lesion with proximity to eloquent brain or radiosensitive structures.
The major differences between these studies and our analysis is that the SVZ in our study was mostly outside the clinical target volume and radiation applied to the SVZ was therefore given in smaller fractions (1.36 Gy, CI: 1.2 - 1.5).
A tumour size < 3 cm and treatment in the post-computerised tomography era were associated with a better prognosis according to univariate analysis, while age, sex, tumour site, treatment volume, the radiation dose to both the primary and the spinal cord and the extent of surgical resection did not influence the prognosis.
The subsequent system failure, meltdown and uncontrolled release of large volumes of radiation at the Tokyo Electric Power Corporation's Fukushima Daiichi nuclear complex has become one of the defining events of our age.
