“…SIRT has been for many years primarily a palliative treatment, so larger uncertainties in absorbed dose calculations have been clinically acceptable. However, the potential of SIRT goes well beyond palliation and the recent correlations between dosimetry and tumor response and survival reveal the progress in understanding the therapeutic benefit of SIRT [24][25][26][27][28][29][30][31] . Accurate and reproducible dose calculations will be needed to optimize the SIRT therapeutic ratio in a consistent manner.…”

“…8 While the use of 99mTc-MAA as a microsphere surrogate has been controversial given that its deposition is susceptible to catheter position, vasospasm, tumor size and vascularity, and differences in particle shape, there is evidence to support its performance in normal liver dose prediction and in larger tumors. [9][10][11][12][13] Following radioembolization, particle distribution can be determined by either bremsstrahlung SPECT/CT or higher resolution Y90 PET/CT with which dose volume histograms can be generated to both normal tissue and tumor. 14,15…”

“…Esto es debido principalmente a que una evaluación dosimétrica adecuada es fundamental para el desarrollo de un plan de tratamiento individualizado y para la optimización de los resultados de la RE [33]. A día de hoy la única forma de llevar a cabo una dosimetría personalizada es realizar los cálculos de la dosis absorbida a partir de la imagen SPECT-CT de la distribución de los 99m Tc-MAA, ya que no existe otra opción de realizar una evaluación dosimétrica previa a la administración del tratamiento [76,103]. El objetivo principal de la dosimetría en los tratamientos de RE es conocer la máxima dosis absorbida tolerada por el tejido tumoral y establecer los límites de dosis por debajo de los cuales se asegura una toxicidad a nivel hepático aceptable.…”

“…Disponer de este factor predictor de la respuesta y la supervivencia antes de la administración del tratamiento supone una ventaja de los tratamientos de RE con respecto a otro tipo de terapias como son la quimioterapia o la quimioembolización. Razón por la cual, aunque aún es necesario realizar avances en la eficiencia de la dosimetría pre-tratamiento, el desarrollo de estudios prospectivos para evaluar la eficacia de la RE en relación con las dosis absorbidas es fundamental [103].…”
