Introduction: Biliary tract cancers (BTC) are rare and aggressive neoplasms. The current management of locally advanced or unresectable BTC is primarily based on chemotherapy (CHT) alone, linked to a median overall survival (OS) of approximately 12 months. However, international guidelines still consider concurrent chemoradiation (CRT) as an alternative treatment option. This study aims to review the current evidence on "modern" CRT for primary or recurrent unresectable BTC. Materials and Methods: A comprehensive search was conducted on PubMed, Scopus, and Cochrane Library to identify relevant papers. Prospective or retrospective trials reporting outcomes after concurrent CRT of unresectable non‐metastatic, primary, or recurrent BTC were included. Only English‐written papers published between January 2010 and June 2022 were considered. Results: Seventeen papers, comprising a total of 1961 patients, were included in the analysis. Among them, 11 papers focused solely on patients with primary unresectable BTC, while two papers included patients with isolated local recurrences and four papers encompassed both settings. In terms of tumor location, 12 papers included patients with intrahepatic, extrahepatic, and hilar BTC, as well as gallbladder cancer. The median CRT dose delivered was 50.4 Gy (range: 45.0–72.6 Gy) using conventional fractionation. Concurrent CHT primarily consisted of 5‐Fluorouracil or Gemcitabine. The pooled rates of 1‐year progression‐free survival (PFS) and OS were 40.9% and 56.2%, respectively. The median 1‐ and 2‐year OS rates were 63.1% and 29.4%, respectively. Grade ≥3 acute gastrointestinal toxicity ranged from 5.6% to 22.2% (median: 10.9%), while grade ≥3 hematological toxicity ranged from 1.6% to 50.0% (median: 21.7%). Conclusion: Concurrent CRT is a viable alternative to standard CHT in patients with locally advanced BTC, offering comparable OS and PFS rates, along with an acceptable toxicity profile. However, prospective trials are needed to validate and further explore these findings. [ABSTRACT FROM AUTHOR]

Brachytherapy (BRT) plays a pivotal role in the treatment of tumors, offering precise radiation therapy directly to the affected area. However, this technique demands extensive training and skills development, posing challenges for widespread adoption and ensuring patient safety. This narrative review explored the utilization of augmented reality (AR) in BRT, seeking to summarize existing evidence, discuss key findings, limitations, and quality of research as well as outline future research directions. The review revealed promising findings regarding the integration of AR in BRT. Studies have suggested the feasibility and potential benefits of AR in education, training, intra-operative guidance, and treatment planning. However, the evidence remains limited and heterogeneous, with most studies in preliminary phases. Standardization, prospective clinical trials, patient-centered outcomes assessment, and cost-effectiveness analysis emerge as critical areas for future research. Augmented reality holds transformative potential for BRT by enhancing precision, safety, and training efficiency. To fully implement these benefits, the field requires standardized protocols, rigorous clinical trials, and in-depth patient-centered investigations. Policy-makers and healthcare providers should closely monitor developments in AR and consider its implementation in clinical practice, contingent and robust evidence, and cost-effectiveness analysis. The pro-active pursuit of evidence-based practices will contribute to optimizing patient care in BRT. [ABSTRACT FROM AUTHOR]

Simulators have revolutionized medical education and training across various disciplines, offering unique advantages in skill acquisition and performance improvement. In the context of interventional radiation therapy (IRT), simulators have emerged as valuable tools for training healthcare professionals in these complex procedures. This narrative review summarized the available evidence on the use of simulators in IRT training, highlighting their impact on proficiency, engagement, and self-confidence as well as their benefits for medical physicists and radiation therapists. A systematic search was conducted in PubMed, resulting in inclusion of 10 papers published since 2009, with 5 of them published since 2020. Publications originated from centers in USA, Ireland, Switzerland, Canada, and Japan, covering a range of IRT settings, including general, prostate, and cervical IRT. The review demonstrated that simulators provide a controlled and realistic environment for skill acquisition, allowing healthcare professionals to practice procedures, optimize image quality, and enhance technical proficiency. The use of simulators addressed the barriers associated with limited caseload and procedural complexity, ultimately contributing to improved education and IRT training. While cost considerations may exist, simulators offer long-term costeffective solutions, balancing the potential benefits in improving educational outcomes and patient care. Overall, simulators play a crucial role in IRT training, enhancing the skills and competence of healthcare providers and improving access to quality IRT care worldwide. Future research should focus on evaluating the long-term impact of simulation-based training on clinical outcomes and patient satisfaction, exploring different simulation models and training approaches, and addressing region-specific barriers to optimize the utilization of IRT.

Background: Sarcopenia (SP) is defined as the quantitative and functional impairment of skeletal muscles. SP is commonly related to older age and is frequent in patients with cancer. To provide an overview of SP in patients treated with radiotherapy (RT) and to evaluate the current evidence, we analyzed the available systematic reviews and meta-analyses. Methods: Reviews were identified using PubMed, Scopus, and Cochrane library databases, without date restriction. Only systematic reviews and meta-analyses on the prognostic impact of SP and on any treatments aimed at reducing SP effect, in patients undergoing RT, were included in this review. The analyses not separately reporting the results in patients treated with RT were excluded. The quality assessment was performed using AMSTAR-2 (A MeaSurement Tool to Assess systematic Reviews). Results: From the 84 papers identified, five reviews met the inclusion criteria with four reports mainly including non-randomized trials. Three reviews on the effect of SP showed a significantly negative impact on overall survival in patients undergoing RT and/or chemoradiation for H&N cancers (HR: 1.63-2.07). Two reviews on interventional studies showed the possibility of 1) improving physical functions through nutritional and physical interventions and 2) avoiding muscle wasting by means of sufficient protein intake. The quality assessment of the included review showed that two and three analyses are classifiable as having low and moderate overall confidence rating, respectively. Conclusions: The analyzed reviews uniformly confirmed the negative impact of SP in patients with H&N tumors undergoing RT and the possibility of improving muscle mass and function through nutritional and physical interventions. These results justify further research on this topic based on a more uniform SP definition and on a complete evaluation of the potentially confounding parameters. [ABSTRACT FROM AUTHOR]
