Special Issue Information

Dear Colleagues,

Radioresistant tumors pose a critical challenge in oncology, often resulting in poor patient outcomes despite ongoing advancements in therapeutic modalities. The aim of this Special Issue, titled "Advanced Research on Radioresistant Tumors", is to provide a comprehensive platform for understanding and overcoming radioresistance, with a focus on the latest advancements in radiotherapy, immunotherapy, chemotherapy, and genetic research.

By covering cutting-edge developments in radiotherapy techniques such as proton and heavy ion therapy, exploring novel genetic findings, and discussing the integration of immunomodulatory strategies, this Issue will offer valuable insights into overcoming treatment barriers and enhancing therapeutic efficacy.

Our objective is to collect a diverse range of articles that not only drive innovation but also serve as a practical guide for clinicians and experts in the field. We aim to create a resource that clinicians can utilize in clinical settings, showcasing the latest findings in specific cancers, highlighting the latest treatment possibilities, and presenting novel ideas for tackling radioresistance. This Special Issue aspires to bridge the gap between research and clinical application, enabling better decision making and improved patient outcomes in the management of radioresistant tumors.

Scope: This Special Issue invites original research articles, reviews, and clinical studies that focus on the following areas:

1. Genetics and Molecular Mechanisms:
New insights into the genetic and molecular pathways driving radioresistance, including novel gene mutations, epigenetic changes, and biomarkers for predicting treatment response.

2. Radiotherapy Innovations:
Emerging techniques, such as proton therapy, heavy ion therapy, and adaptive radiotherapy, aimed at overcoming hypoxia and improving local control in resistant tumors.

3. Immunotherapy Strategies:
Integrating radiotherapy with immunotherapy approaches, such as immune checkpoint inhibitors, cancer vaccines, and adoptive cell therapy, to boost anti-tumor immune responses.

4. Chemotherapy and Combination Treatments:
Investigations into the synergistic effects of combining radiotherapy with chemotherapy, targeted therapies, or molecular inhibitors to sensitize tumors to radiation.

5. Personalized Approaches:
Utilizing advanced imaging and genetic profiling to adapt radiotherapy and multimodal treatments to the unique characteristics of individual tumors.

Background: This work presents the procedures and application of the deep inspiration breath-hold (DIBH) technique for mediastinal lymphoma patients at a proton therapy (PT) center. It also discusses the implementation and validation of the surface-guided radiotherapy (SGRT) protocol in terms of positioning accuracy. Methods: This study included six lymphoma patients. Dedicated computed tomography (CT) protocols and a treatment workflow based on international guidelines were developed. Clinical data from the treatment planning system (TPS) were used to assess the difference between DIBH and free-breathing irradiation. Additionally, data from an optical patient positioning system and kilovoltage (kV) imaging system were used to estimate positioning shifts. The new CT protocol reduced the volume CT dose index by over six times compared with the standard protocol. Results: The DIBH method decreased the mean dose to the heart and lungs by up to 7.02 Gy(RBE) and 0.83 Gy(RBE), respectively. The median magnitude of patient setup errors and repeatability in DIBH positioning was 0.4 cm and 0.18 cm (mean for males and females) for the SGRT protocol. The kV imaging showed a setup error of over 0.3 cm for both groups. Conclusions: Despite the small size of the patient cohort, the relatively large number of individual positioning sessions enabled the detection of statistically significant differences (p < 0.05) in certain areas between male and female patients; however, no significant difference in the displacement vector magnitude was observed. DIBH treatment with SGRT offers high reproducibility for patient positioning. Full article
