Special Issue Information

Dear Colleagues,

We are inviting submissions to the Special Issue on "Internal and/or External Radiotherapy and Dosimetric Evaluation: From Cellular Level to the Patient", which aims to cover the recent outstanding developments of radiotherapy and nuclear medicine treatments.  

Radiotherapy and nuclear medicine have a central role in the multidisciplinary field of oncology, either considered individually as possible way to irradiate tumors in combination with other modalities of treatment or in a combination of internal and external radiotherapy.

In recent years, both have experienced great improvements and developments, such as the increased number of particle therapy facilities worldwide; the concept of "theranostic"; a deeper understanding of tumor biology; improvements in imaging (together with radiomics and deep learning methods) from diagnosis and staging passing through treatment and finally to follow-up.

Although these are some of the goals achieved, the answers to questions ranging from the cellular level down to the patient remain opened. Some examples are: the possibility of using spectroscopy investigations to study cancer cell radioresistance; the basis to trigger a certain type of cell death after ionizing radiation treatment; the precise dosimetry evaluation of the treatment performed; dosimetric and radiobiological impact related to the treatment schedule with the possibility of a less toxic effect to normal tissues or improved tumor control/survival.

In this Special Issue, we invite you to contribute with original research articles exploring application of radiotherapy and/or nuclear medicine therapy on cell cultures and/or patients. Theoretical and experimental studies are welcome for submission, as well as are comprehensive reviews and editorials.

Potential topics include, but are not limited to:

  • Basic research on cell cultures exposed to ionizing radiation;
  • Spectroscopic investigation on cell cultures exposed to ionizing radiation;
  • Dosimetry and radiobiological study at the cellular and/or animal level;
  • Radiobiology analysis of in vitro assays with tumor cell lines and in animal models of cancer;
  • Diagnostic nuclear medicine (PET, SPECT, and hybrid imaging);
  • Quantitative imaging;
  • Advances in nuclear medicine dosimetry;
  • Therapeutic nuclear medicine;
  • Advances in radiotherapy planning and delivery;
  • Basic research in radiotherapy;
  • Pre-treatment and/or in vivo dosimetric evaluation of ionizing radiation treatments or online dosimetry;
  • Software and instruments for dose assessment;
  • Radiomics;
  • Predictive models.

(1) Background: In 90Y-TARE treatments, lung-absorbed doses should be calculated according to the manufacturer’s instructions, using the MIRD-scheme. This scheme is derived from the assumption that 90Y-microspheres deliver the dose in a water-equivalent medium. Since the density of the lungs is quite different from that of the liver, the absorbed dose to the lungs could vary considerably, especially at the liver/lungs interface. The aim of this work is to compare the dosimetric results obtained by two dedicated software packages implementing a water-equivalent dose calculation and a Monte Carlo (MC) simulation, respectively. (2) Methods: An anthropomorphic IEC phantom and a retrospective selection of 24 patients with a diagnosis of HCC were taken into account. In the phantom study, starting from a 90Y-PET/CT acquisition, the liver cavity was manually fixed with a uniform activity concentration on PET series, while the lung compartment was manually expanded on a CT series to simulate a realistic situation in which the liver and lungs are adjacent. These steps were performed by using MIM 90Y SurePlan. Then, a first simulation was carried out with only the liver cavity filled, while a second one was carried out, in which the lung compartment was also manually fixed with a uniform activity concentration corresponding to 10% lung shunt fraction. MIM 90Y SurePlan was used to obtain Voxel S-Value (VSV) approach dose values; instead, Torch was used to obtain MC approach dose values for both the phantom and the patients. (3) Results: In the phantom study, the percentage mean dose differences (∆D%) between VSV and MC in the first and second simulation, respectively were found to be 1.2 and 0.5% (absolute dose variation, ∆D, of 0.7 and 0.3 Gy) for the liver, −56 and 70% (∆D of −0.3 and −16.2 Gy) for the lungs, and −48 and −60% (∆D of −4.3 and −16.5 Gy) for the Liver/Lungs Edge region. The patient study reports similar results with ∆D% between VSV and MC of 7.0%, 4.1% and 6.7% for the whole liver, healthy liver, and tumor, respectively, while the result was −61.2% for the left lung and −61.1% for both the right lung and lungs. (4) Conclusion: Both VSV and MC allowed accurate radiation dose estimation with small differences (<7%) in regions of uniform water-equivalent density (i.e., within the liver). Larger differences between the two methods (>50%) were observed for air-equivalent regions in the phantom simulation and the patient study. Full article
