Summary: The purpose of this study was to identify predictors of disease progression in early-stage non-small cell lung cancer (NSCLC) patients after receiving definitive stereotactic body radiation therapy (SBRT). The results showed that tumor diameter and SUVmax were the most frequently reported features associated with progression/survival, and a re-fitted model including these two features had the best performance.

Summary: There is a lack of comparative effectiveness research on new treatment modalities for localized prostate cancer. This study aimed to compare the impact of active surveillance, robot-assisted radical prostatectomy (RARP), intensity-modulated radiotherapy (IMRT), and real-time brachytherapy using Patient-Reported Outcome Measures (PROMs). The results showed that active surveillance had the fewest side effects, but led to significant deterioration in sexual and physical health, while showing moderate improvement in mental health. RARP had greater urinary incontinence, and IMRT and real-time brachytherapy were associated with worse bowel symptoms. Most side effects seemed to be limited to short-term deteriorations.

Summary: This paper proposes a method for high-quality SPET reconstruction using low-dose PET images and T1 acquisitions from MRI. It extracts local spatial features from different modalities using separate CNN encoders and integrates these features effectively using a multimodal feature integration module. It further uses a Transformer-based encoder to extract global semantic information and a CNN decoder to transform the encoded features into SPET images. Additionally, a patch-based discriminator and an edge-aware loss are applied to retain edge detail information in the reconstructed SPET images. Experimental results demonstrate that the proposed method outperforms current state-of-the-art methods in reconstructing high-quality SPET images.

Summary: This systematic review evaluates the potential effectiveness of targeting hypoxia-induced radioresistance in rectal cancer and highlights the importance of further research in this area. There is a need for more preclinical and clinical studies to fully understand the mechanism behind this radioresistance. Promising targets have been identified, but more research is needed.

Summary: A dedicated PET tomograph has great clinical utility in examining the prostate gland, particularly in assessing high-risk patients before biopsy. It can reduce the need for biopsy samples, define tumor location, assist in focal therapies, and improve N staging accuracy in this potentially fatal malignancy.

Summary: This study assessed the accuracy of 3-D surface rendering of 2-D ultrasound images of the uterus using FMRA software for mapping uterine fibroids compared to pathological evaluation. The results showed good correlation between the two methods in terms of fibroid size and location. Inter-observer analysis also demonstrated reproducibility of measurements from two sonologists using the 3-D model.

Summary: Sparse reconstruction is important in MRI for reducing acquisition time and improving spatial-temporal resolution. This paper introduces two decoupling techniques for explicit 1D regularization and a combined 1D + 2D reconstruction technique that improves image quality.

Summary: Purpose: This study evaluates the frequency of progressive disease (PD) as determined by the Response Evaluation Criteria in Solid Tumors (RECIST) following lung stereotactic ablative radiotherapy (SABR), and correlates this with actual treatment outcomes. The results show that most lesions identified as PD by RECIST criteria do not represent recurrence, highlighting the limitations of RECIST in this setting.

Summary: This study investigates an altered version of an existing protocol to study the mechanisms and phenomena of stimulated luminescence. The protocol allows for the examination of recombination mechanisms and trapping parameters of the traps, as well as the observation of potential transitions between two different states.

Summary: This study analyzed articles about radiation oncology published in The New York Times since its inception in 1851, and identified changes in media sentiment and prevalent themes related to radiotherapy. The findings suggest an increasing negative sentiment in media coverage towards radiotherapy, with a shift towards reporting treatment errors, toxicity, and ineffectiveness.

Summary: This study evaluates the efficacy and toxicity of carbon ion radiotherapy (CIRT) in locally advanced head and neck mucosal melanoma patients. The results show that CIRT is safe and effective in treating the local region, and immunotherapy after relapse can improve overall survival. However, further prospective trials are needed to assess the role of targeted/immune- systemic therapy in this disease.

Summary: This study aimed to develop CT radiomics models to preoperatively identify lymph node (LN) status in resectable esophageal squamous cell carcinoma (ESCC) patients. The results showed that the combined model, integrating ESCC and LN radiomics features with clinical features, had the highest predictive ability among the three models. The combined model's predictive ability was validated in both the test and external validation cohorts.

Summary: mpMR imaging is a valuable tool for diagnosing and staging prostate cancer, often superior to traditional methods. Standardized protocols aid in evaluating prostate mpMR imaging. Radiologists need to thoroughly study prostate imaging and be aware of potential pitfalls. Additional sequences can improve tumor detection sensitivity. This study emphasizes the importance of recognizing factors that complicate prostate MR imaging interpretation.
