Lv M, Feng Y, Zeng S, Zhang Y, Shen W, Guan W, E X, Zeng H, Zhao R and Yu J
Recent research has demonstrated that the use of artificial intelligence (AI) in radiotherapy (RT) has significantly streamlined the process for physicians to treat patients with tumors; however, bibliometric studies examining the correlation between AI and RT are not available. Providing a thorough overview of the knowledge structure and research hotspots between AI and RT was the main goal of the current study.

Intrahepatic cholangiocarcinoma (ICC) is a challenging primary liver cancer with a poor prognosis, especially in unresectable cases. Traditional palliative irradiation is limited in reducing liver doses. This study aimed to evaluate the efficacy and toxicity of respiratory-gated proton beam therapy without fiducial markers for intrahepatic cholangiocarcinoma.
Toxicity assessment following conventional radiation therapy and pulsed low dose rate radiation therapy: an in vivo animal study
Salem NR, Eldib A, El-Sayed EM, Mostafa E and Desouky OS
Pulsed low dose rate radiotherapy (PLDR) is a new radiation delivery method, in which the fractional dose is divided into sub-fractional doses with periodical time breaks in between. The goal of our study is to assess the toxicity on healthy tissues resulting from PLDR as compared to conventional radiotherapy (CRT) using the same physical X-ray dose.
Stereotactic radiotherapy for patients with bone metastases: a selected group with low rate of radiation treatment during the last month of life?
Nieder C, Haukland EC, Stanisavljevic L and Mannsåker B
Complex high-precision radiotherapy, such as stereotactic body radiotherapy (SBRT), should only be offered to patients with sufficiently long survival. In the context of bone metastases radiotherapy, low rates of treatment close to the end of life, e.g. last 30 days (RT30), may serve as a quality of care indicator. While traditional, pain-relieving short-course regimens have been studied comprehensively, real-world SBRT results are still limited.
Dose prediction of CyberKnife Monte Carlo plan for lung cancer patients based on deep learning: robust learning of variable beam configurations
Miao Y, Li J, Ge R, Xie C, Liu Y, Zhang G, Miao M and Xu S
Accurate calculation of lung cancer dose using the Monte Carlo (MC) algorithm in CyberKnife (CK) is essential for precise planning. We aim to employ deep learning to directly predict the 3D dose distribution calculated by the MC algorithm, enabling rapid and accurate automatic planning. However, most current methods solely focus on conventional intensity-modulated radiation therapy and assume a consistent beam configuration across all patients. This study seeks to develop a more versatile model incorporating variable beam configurations of CK and considering the patient's anatomy.

Ghanikolahloo M, Taher HJ, Abdullah AD, Asadi Anar M, Tayebi A, Rahimi R, Olamaeian F, Rahimikashkooli N and Kargar N
The present study aimed to evaluate the use of F-2-[F]-fluoro-2-deoxy-d-glucose (FDG) PET/MRI (Positron emission tomography-computed tomography) in predicting the pathological response to neoadjuvant chemotherapy (NAC) in patients with breast cancer (BC) compared to the use of MRI (Magnetic Resonance Imaging) alone.
Efficacy and safety of tyrosine kinase inhibitors with thoracic radiotherapy for patients with oncogene-mutated non-small cell lung cancer: a meta-analysis
Li W, Wu P, Liang Z, Li L, Chen Y, Zhang W, Zhang H and Fang C
Tyrosine Kinase Inhibitors (TKIs) is an important therapy for patients with oncogene-mutated Non-Small Cell Lung Cancer (NSCLC). However, acquired resistance remains a major challenge. The efficacy of TKIs plus thoracic radiotherapy (RT) in oncogene-mutated NSCLC patients is uncertain. Therefore, we performed a meta-analysis to comprehensively evaluate the efficacy and safety of thoracic RT plus TKIs in oncogene-mutated NSCLC patients.
Timing matters: diurnal spine length variation in pediatric patients during radiotherapy
Meijer KM, van Dijk IWEM, Schonk TJ, Balgobind BV, Loginova A, van Wieringen N and Bel A
During the day-night cycle, gravity and applied stress to the body mass and spine causes a decrease in body height, which is restored overnight. This diurnal spine length variation has not yet been quantified during radiotherapy. Therefore, we aimed to quantify diurnal spine length variation on cone beam CTs (CBCTs) of pediatric patients (< 18 years) who underwent radiotherapy.
Analysis of urinary function and prostate volume changes in localized prostate cancer patients treated with carbon-ion radiotherapy; a prospective study
Miyazawa Y, Nakayama H, Kawamura H, Miyasaka Y, Onishi M, Kaminuma T, Sekine Y, Matsui H, Ohno T and Suzuki K
The potential of carbon ion radiation therapy (CIRT) as a curative treatment for localized prostate cancer (PCa) has garnered attention due to its characteristic dose distribution. We prospectively collected and analyzed over five years to investigate the outcomes of localized PCa treated with CIRT at our institution.
Pneumonitis after normofractionated radioimmunotherapy: a method for dosimetric evaluation
Kraus KM, Bauer C, Steinhelfer L, Feuerecker B, Martins JC, Fischer JC, Borm KJ, Peeken JC, Bernhardt D and Combs SE
Post-Therapy-Pneumonitis (PTP) is a critical side effect of both, thoracic radio(chemo)therapy (R(C)T) and immune checkpoint inhibition (ICI). However, disease characteristics and patient-specific risk factors of PTP after combined R(C)T + ICI are less understood. Given that RT-triggered PTP is strongly dependent on the volume and dose of RT [1], driven by inflammatory mechanisms, we hypothesize that combination therapy of R(C)T with ICI influences the dose-volume-effect correlation for PTP. This study focuses on the development of a method for evaluation of alterations of dosimetric parameters for PTP after R(C)T with and without ICI.
Cost-effectiveness analysis of additional local prostate radio therapy in metastatic prostate cancer from a medicare perspective
Kramer KKM, Schmidt-Hegemann NS, Westhofen T, Foglar M, Ricke J, Westphalen CB, Unterrainer M, Kunz WG and Mehrens D
Metastatic prostate cancer remains a therapeutic challenge. Based on data of the STAMPEDE trial, patients with a low metastatic burden showed prolonged failure-free and overall survival when treated with prostate radio therapy (RT) in addition to standard of care (SOC). The objective of this study was to determine the cost-effectiveness of additional prostate RT compared to SOC alone for following subgroups: non-regional lymph node (NRLN) metastases, up to three bone metastases and four or more bone metastases.
Artificial intelligence contouring in radiotherapy for organs-at-risk and lymph node areas
Meyer C, Huger S, Bruand M, Leroy T, Palisson J, Rétif P, Sarrade T, Barateau A, Renard S, Jolnerovski M, Demogeot N, Marcel J, Martz N, Stefani A, Sellami S, Jacques J, Agnoux E, Gehin W, Trampetti I, Margulies A, Golfier C, Khattabi Y, Olivier C, Alizée R, Py JF and Faivre JC
The delineation of organs-at-risk and lymph node areas is a crucial step in radiotherapy, but it is time-consuming and associated with substantial user-dependent variability in contouring. Artificial intelligence (AI) appears to be the solution to facilitate and standardize this work. The objective of this study is to compare eight available AI software programs in terms of technical aspects and accuracy for contouring organs-at-risk and lymph node areas with current international contouring recommendations.
Prognostic value of neutrophil to lymphocyte ratio and lymphocyte counts before durvalumab consolidation after radio-chemotherapy in locally advanced non-small cell lung cancer
Colomb A, Allignet B, Lamkhioued M, Swalduz A, Falchero L, Kienlen A, Duruisseaux M and Moncharmont C
Durvalumab, an anti-PD-L1 immune checkpoint inhibitor, after radio-chemotherapy (RCT) has changed the management of locally advanced non-small cell lung cancer (LA NSCLC). A series of retrospective studies have investigated different cut-off of lymphocyte count (LyC) and neutrophil-to-lymphocyte ratio (NLR) to predict survival in LA NSCLC. None of these studies has validated their threshold in an independent group of patients. We wanted to assess the OS prognostic value of NLR and LyC in patients with LA NSCLC treated by RCT and durvalumab, with threshold determination and their validation in an external cohort.

Johnson PB, Bradley J, Lampotang S, Jackson A, Lizdas D, Johnson W, Brooks E, Vega RBM and Mendenhall N
The purpose of this study is to assess the feasibility of mixed-reality (MixR) visualization for patient setup in breast and chest wall radiotherapy (RT) by performing a first-in-human clinical trial comparing MixR with a 3-point alignment.
Growth differentiation factor 15 (GDF15) predicts relapse free and overall survival in unresected locally advanced non-small cell lung cancer treated with chemoradiotherapy
Di Pastena F, Pond G, Tsakiridis EE, Gouveia A, Ahmadi E, Biziotis OD, Ali A, Swaminath A, Okawara G, Ellis PM, Abdulkarim B, Ahmed N, Robinson A, Roa W, Valdes M, Kavsak P, Wierzbicki M, Wright J, Steinberg G and Tsakiridis T
Growth differentiation factor 15 (GDF15) is a cytokine of the TGFβ family. Here, we analyzed GDF15 levels in patients with locally advanced non-small cell lung cancer (LA-NSCLC) who participated in OCOG-ALMERA (NCT02115464), a phase II randomized clinical trial, that investigated metformin in combination with standard of care concurrent chemoradiotherapy (cCRT). OCOG-ALMERA was not able to demonstrate benefit in the metformin arm. Therefore, biomarker studies are needed to better define stratification parameters for future trials.
