Eligibility for Adjuvant Cyclin-Dependent Kinase 4/6 Inhibitors in Endocrine Receptor-Positive and HER2-Negative Early Breast Cancer by Age and Type of Surgery.

Despite early diagnosis, approximately 20% of patients with ER-positive and HER2-negative breast cancer (BC) will experience disease recurrence. Improved survival has been reported with adjuvant treatment combining cyclin-dependent kinase 4/6 inhibitors with endocrine therapy, in high-risk patients with ER-positive and HER2-negative BC, regardless of age. Older patients have higher rates of ER-positive/HER2-negative BC than younger patients.

Radiomics-driven personalized radiotherapy for primary and recurrent tumors: A general review with a focus on reirradiation.

Purpose: This review systematically investigates the role of radiomics in radiotherapy, with a particular emphasis on the use of quantitative imaging biomarkers for predicting clinical outcomes, assessing toxicity, and optimizing treatment planning. While the review encompasses various applications of radiomics in radiotherapy, it particularly highlights its potential for guiding reirradiation of recurrent cancers.

Methods: A systematic review was conducted based on a Medline search with the search engine PubMed using the keywords "radiomics or radiomic" and "radiotherapy or reirradiation".

CYRAD: a translational study assessing immune response to radiotherapy by photons or protons in postoperative head and neck cancer patients through circulating leukocyte subpopulations and cytokine levels.

Background: Radiotherapy has both immunostimulant and immunosuppressive effects, particularly in radiation-induced lymphopenia. Proton therapy has demonstrated potential in mitigating this lymphopenia, yet the mechanisms by which different types of radiation affect the immune system function are not fully characterized. The Circulating Immunes Cells, Cytokines and Brain Radiotherapy (CYRAD) trial aims to compare the effects of postoperative X-ray and proton radiotherapy on circulating leukocyte subpopulations and cytokine levels in patients with head and neck (CNS and ear nose throat) cancer.

Postoperative rectovaginal fistula: stoma may not be necessary-a French retrospective cohort.

Background: Postoperative rectovaginal fistula leads to a loss of patients' quality of life and presents significant challenges to the surgeon. The literature focusing specifically on postoperative rectovaginal fistulas is limited. The objective of the present study is to identify factors that can enhance the success of the management of this postoperative rectovaginal fistula.

Where do we stand with screening for colorectal cancer and advanced adenoma based on serum protein biomarkers? A systematic review.

Colorectal cancer (CRC) screening has been proven to reduce both mortality and the incidence of this disease. Most CRC screening programs are based on fecal immunochemical tests (FITs), which have a low participation rate. Searching for blood protein biomarkers can lead to the development of a more accepted screening test.

Contribution of [F]FET PET in the Management of Gliomas, from Diagnosis to Follow-Up: A Review.

Gliomas, the most common type of primary malignant brain tumors in adults, pose significant challenges in diagnosis and management due to their heterogeneity and potential aggressiveness. This review evaluates the utility of O-(2-[F]fluoroethyl)-L-tyrosine ([F]FET) positron emission tomography (PET), a promising imaging modality, to enhance the clinical management of gliomas. We reviewed 82 studies involving 4657 patients, focusing on the application of [F]FET in several key areas: diagnosis, grading, identification of IDH status and presence of oligodendroglial component, guided resection or biopsy, detection of residual tumor, guided radiotherapy, detection of malignant transformation in low-grade glioma, differentiation of recurrence versus treatment-related changes and prognostic factors, and treatment response evaluation.

Radiosensitizing Effect of PARP Inhibition on Chondrosarcoma and Chondrocyte Cells Is Dependent on Radiation LET.

Chondrosarcoma is a rare malignant tumor that forms in bone and cartilage. The primary treatment involves surgical removal of the tumor with a margin of healthy tissue. Especially if complete surgical removal is not possible, radiation therapy and chemotherapy are used in conjunction with surgery, but with a generally low efficiency.

Role of Oxidative Stress Signaling, Nrf2, on Survival and Stemness of Human Adipose-Derived Stem Cells Exposed to X-rays, Protons and Carbon Ions.

Some cancers have a poor prognosis and often lead to local recurrence because they are resistant to available treatments, e.g., glioblastoma.

Differential plasma cytokine variation following X-ray or proton brain irradiation using machine-learning approaches.

Purpose: X-ray and proton irradiation have been reported to induce distinct modifications in cytokine expression in vitro and in vivo, suggesting a dissimilar inflammatory response between X-rays and protons. We aimed to investigate the differences in cytokine profiles early following fractionated brain irradiation with X-rays or protons and their relationship with leukocyte subpopulations in rodents.

Materials And Methods: Our study utilized data from 80 tumor-free mice subjected to X-ray or proton brain irradiation in four fractions of 2.

Trastuzumab Deruxtecan after Endocrine Therapy in Metastatic Breast Cancer.

Background: Outcomes in patients with hormone receptor-positive metastatic breast cancer worsen after one or more lines of endocrine-based therapy. Trastuzumab deruxtecan has shown efficacy in patients with metastatic breast cancer with low expression of human epidermal growth factor receptor 2 (HER2) after previous chemotherapy.

Methods: We conducted a phase 3, multicenter, open-label trial involving patients with hormone receptor-positive metastatic breast cancer with low HER2 expression (a score of 1+ or 2+ on immunohistochemical [IHC] analysis and negative results on in situ hybridization) or ultralow HER2 expression (IHC 0 with membrane staining) who had received one or more lines of endocrine-based therapy and no previous chemotherapy for metastatic breast cancer.

Capmatinib efficacy for METex14 non-small cell lung cancer patients: Results of the IFCT-2104 CAPMATU study.

Background: Capmatinib is a selective MET inhibitor with demonstrated efficacy in a phase II study of non-small cell lung cancer (NSCLC) patients harboring METex14 mutations. However, the real-world outcomes of capmatinib are largely unknown. From June 2019, the French Early Access Program (EAP) provided capmatinib to METex14 NSCLC patients who were ineligible for or for whom first-line standard therapies had failed.

Influence of age and self-stigmatization on social eating and drinking issues in French outpatients living with and beyond head and neck cancer: a mixed-method study.

Purpose: Social eating (SE) is a corner stone of daily living activities, quality of life (QoL), and aging well. In addition to feeding functional disorders, patients with head and neck cancer (HNC) face individual and social psychological distress. In this aging population, we intended to better assess the influence of age on these challenges, and the role of self-stigmatization limiting SE in patients with and beyond HNC.

Particle Beam Radiobiology Status and Challenges: A PTCOG Radiobiology Subcommittee Report.

Particle therapy (PT) represents a significant advancement in cancer treatment, precisely targeting tumor cells while sparing surrounding healthy tissues thanks to the unique depth-dose profiles of the charged particles. Furthermore, their linear energy transfer and relative biological effectiveness enhance their capability to treat radioresistant tumors, including hypoxic ones. Over the years, extensive research has paved the way for PT's clinical application, and current efforts aim to refine its efficacy and precision, minimizing the toxicities.

Long-term behavioral symptom clusters among survivors of early-stage breast cancer. development and validation of a predictive model.

Background: Fatigue, cognitive impairment, anxiety, depression, and sleep disturbance are cancer-related behavioral symptoms (CRBS) that may persist years after early-stage breast cancer (BC), affecting quality of life. We aimed at generating a predictive model of long-term CRBS clusters among BC survivors four years post-diagnosis.

Methods: Patients with early-stage BC were included from the CANcer TOxicity (NCT01993498).

A randomised study to evaluate the potential added value of shared meditation involving people with cancer, health professionals and third persons compared to meditation conducted with patients only: design of the Implic-2 protocol.

Background: In oncology, the suffering of patients and the burnout of health professionals are key issues. Mindfulness meditation is a holistic approach that can help to improve well-being. While numerous studies have shown the benefits of meditation for both patients and health professionals, the added value of offering shared meditation to groups of patients, health professionals and third persons has not been assessed.

Local relapse patterns after preoperative radiotherapy of limb and trunk wall soft tissue sarcomas: Prognostic role of imaging and pathologic response factors.

Purpose: To retrospectively identify clinical, pathologic, or imaging factors predictive of local relapse (LR) after preoperative radiotherapy (RT) for soft tissue sarcomas (STS).

Methods And Materials: This is a retrospective multicenter study of patients who underwent preoperative RT and surgery for limb or trunk wall STS between 2007 and 2018 in French Sarcoma Group centers and were enrolled in the "Conticabase". Patterns of LR were investigated taking into account the multimodal response after preoperative RT.

Background: The impact of geographical accessibility on cancer survival has been investigated in few studies, with most research focusing on access to reference care centers, using overall mortality and limited to specific cancer sites. This study aims to examine the association of access to primary care with mortality in excess of patients with the 10 most frequent cancers in France, while controlling for socioeconomic deprivation.

Methods: This study included a total of 151,984 cases diagnosed with the 10 most common cancer sites in 21 French cancer registries between 2013 and 2015.

Machine learning and deep learning prediction of patient specific quality assurance in breast IMRT radiotherapy plans using Halcyon specific complexity indices.

Introduction: New radiotherapy machines such as Halcyon are capable of delivering dose-rate of 600 monitor-units per minute, allowing large numbers of patients treated per day. However, patient-specific quality assurance (QA) is still required, which dramatically decrease machine availability. Innovative artificial intelligence (AI) algorithms could predict QA result based on complexity metrics.
