Article Synopsis
  • Brain radiation necrosis (BRN) is a serious complication of stereotactic radiotherapy, making it crucial to differentiate it from tumor recurrence using advanced diagnostic techniques.
  • BRN often appears months to years after treatment, with symptoms and MRI changes, influenced by factors like the amount of brain tissue irradiated and radiation dose.
  • Management strategies vary; asymptomatic cases may require monitoring, while symptomatic BRN typically responds to corticosteroids, and emerging treatments like bevacizumab show promise; ongoing research aims to improve outcomes for patients.

Radiotherapy for adolescents and young adults is complex in several aspects. The population is very heterogeneous and has characteristics derived from both paediatric and adult populations both in terms of pathology (anatomical pathology, response to treatment) and the patient's physical, biological and psychological characteristics. This article reviews the characteristics to be taken into account in adolescent and young adult patients radiotherapy and more particularly in some of the most common diseases.

Purpose: Haematologic malignancies are particular in that they can generally be cured, even when distant metastases are present at diagnosis, unlike solid malignancies. Systemic treatments, including chemotherapy, targeted therapies, and immunotherapy, are the standard of care with excellent results. The considerable progress made in the management of these diseases in the last 20years has redefined the role of radiation therapy as minor in many clinical situations.

Article Synopsis
  • Despite advancements in HPV vaccination and screening, about 5% of cervical cancer cases are initially diagnosed at a metastatic stage, with many patients experiencing recurrence after treatment.
  • Treatment options for recurrent or metastatic cervical cancer are currently limited, with traditional therapies primarily involving platinum-based drugs, paclitaxel, and newer immune checkpoint inhibitors showing promise for longer survival.
  • The potential for radiation therapy to induce an abscopal effect—where treatment at one site impacts tumors beyond that area—may enhance therapeutic outcomes when combined with immune therapies, suggesting a new direction in managing metastatic cervical cancer.

  • - A 2021 survey of French radiation oncology residents found that 80% feel their brachytherapy training is inadequate, even though interest in the field remains high at 86% participation.
  • - While proficiency in certain brachytherapy techniques has slightly improved since 2012, significant gaps remain, especially in prostate brachytherapy, with many residents reporting minimal hands-on experience.
  • - Major barriers to effective training include the necessity of visiting multiple centers for different treatments, insufficient brachytherapy activities at their home institutions, and competing hospital responsibilities, highlighting the need for improved structured training programs.

Thanks to proper training and a favorable working environment, nurses nowadays not only take care of central venous catheter (Picc Line and implantable chambers) for patients of a cancer treatment center, but also take charge of the pre-operation consultations required for an effective planning. Under anaesthesist's guidance and care, they were able to tackle a Regional Health Authority approved challenge. Patients themselves reacted favorably to this new structure that was deemed satisfactory, both in stress and patient management terms.

Article Synopsis
  • The study aimed to assess the occurrence of the abscopal response (AR) in metastatic melanoma patients undergoing palliative radiotherapy, focusing on those receiving specific conditions of systemic treatments.
  • Out of 118 patients analyzed, 15 (12.7%) exhibited an AR, showing significantly improved overall survival and progression-free survival compared to those without an AR.
  • The findings suggest that AR is a rare but important indicator of better prognosis and may be enhanced by concurrent treatments like immunotherapy and infections during radiotherapy.

The invention and approval of innovative anticancer therapies in the last decade have revolutionized oncology treatment. Radiotherapy is one of the three traditional pillars in oncology treatment with surgery and systemic therapies. Some standard-of-care combinations of chemoradiotherapy widened the therapeutic window of radiation, while some other chemotherapies such as gemcitabine caused unacceptable toxicities when combined with radiation in lung cancers.

Translational research in radiation oncology is undergoing intense development. An increasingly rapid transfer is taking place from the laboratory to the patients, both in the selection of patients who can benefit from radiotherapy and in the development of innovative irradiation strategies or the development of combinations with drugs. Accelerating the passage of discoveries from the laboratory to the clinic represents the ideal of any translational research program but requires taking into account the multiple obstacles that can slow this progress.

Article Synopsis
  • * Because the prognosis for these patients can be poor without radiotherapy, it should be avoided unless absolutely necessary, and when required, should be tailored to reduce the chance of additional malignancies.
  • * Multidisciplinary teams should evaluate the specific risks associated with germline TP53 variants and overall patient prognosis, promoting the use of methods like proton therapy and non-ionizing imaging to minimize genotoxic effects.

Purpose: Low-dose-rate brachytherapy is a key treatment for low-risk or favorable intermediate-risk prostate cancer. The number of radioactive seeds inserted during the procedure depends on prostate volume, and is not easy to predict without pre-planning. Consequently, a large number of unused seeds may be left after treatment.
