Summary: The study demonstrated that [F-18]SynVesT-1 has excellent imaging and binding properties in humans, with fast and high brain uptake, appropriate tissue kinetics, high levels of specific binding, and excellent test-retest reproducibility. Therefore, [F-18]SynVesT-1 is proven to be a favorable radiotracer for SV2A imaging and quantification in humans.

Summary: The study aimed to assess the prognostic value of asphericity (ASP) and standardized uptake ratio (SUR) in cervical cancer patients. A retrospective analysis was conducted on 508 previously untreated cervical cancer patients. The study showed that ASP and metabolic tumor volume (MTV) were prognostic factors for all investigated endpoints, while SUR and maximum standardized uptake value (SUVmax) were not. The alternative parameter ASP has the potential to improve the prognostic value of [F-18]FDG PET/CT for event-free survival and locoregional control in radically treated cervical cancer patients.

Summary: Discussions on reproducibility in the life sciences are raising doubts about the credibility of experimental outcomes. Experimental evolution, often excluded from these discussions, also faces issues with reproducibility due to contingencies affecting the evolutionary process. While standardization is commonly seen as a solution for internal validity in experimental studies, it may reduce external validity and reproducibility. Alternative approaches, such as systematic heterogenization of experimental factors, are proposed as promising solutions, drawing insights from animal research and ecology.

Summary: This study compared the performance of F-18-FDG PET/MRI and PET/CT in the clinical evaluation of pancreatic neoplasms. The results showed that both PET/MRI and PET/CT had comparable overall performance in identifying pancreatic neoplasms. However, PET/MRI showed better performance for patients with suspected pancreatic neoplasms but no visible FDG uptake on PET/CT.

Summary: This study investigated the potential of a multimodal combination of imaging parameters for classifying patients with locally advanced cervical cancer (LACC). The results showed that the multimodal combination of MR and FDG-PET/CT images improved the classification of LACC patients compared to single modality images and clinical factors. The hypoxic fraction (HF) was identified as an important multimodal biomarker that increased the accuracy of identifying high-risk patients.

Summary: Evidence-Based Medicine encourages clinicians to seek reputable evidence, with randomized controlled trials considered the least biased. However, RCTs often face issues with poor generalizability, hindering the translation of clinical research into practice. Factors contributing to this lack of generalizability have not been fully summarized.

Summary: This study aimed to investigate whether volume-based PET metrics (tumor volume and total lesions glycolysis) are superior to SUVmax and other metrics in predicting survival of patients with soft tissue and bone sarcomas. The results showed that different sarcoma types were associated with different PET/CT metrics, with SUVmax remaining the best prognostic factor in soft tissue sarcomas, while tumor volume may be more suitable for evaluating bone sarcomas.

Summary: The BPL reconstruction algorithm significantly increased SUVmax, SUVmean, and SBR while decreasing MTV of tumor lesions, especially in small or relatively hypometabolic lesions. The differences between BPL and OSEM + TOF were higher compared to those between BPL and OSEM + TOF + PSF. Significant correlations were found between parameter variations and the size and degree of [F-18]FDG uptake in the lesions.

Summary: The progression of cancer is influenced by evolutionary dynamics in both the tumor population and its host. Host species can evolve defense strategies, both immunologic and non-immunologic, against tumors over generations. However, cancer cell plasticity allows for effective counter strategies against host defenses.

Summary: This study conducted in a tertiary care center in India found a high prevalence of cognitive impairment in ART naive patients with HIV, with a particular impact on simple motor skills and memory. However, there was no significant difference in brain metabolites concentration between patients with cognitive impairment and those without cognitive impairment. Further longitudinal studies are needed to understand the underlying pathophysiological mechanisms.

Summary: Evidence suggests that cells at the tumor stromal interface express higher levels of proteins related to glycolytic metabolism, leading to acid production which is associated with increased metastatic potential. The molecular machinery responsible for acid export is being studied, and neutralizing the acidity may prevent local invasion and metastasis.

Summary: Implementing an advanced spatial penalty-based reconstruction at 1.5 T can provide a suitable alternative to the traditional IVIM-DKI model at 3 T for clinical characterization of prostate cancer and benign prostatic hyperplasia. The novel model with TV spatial penalty function showed lower estimation errors and improved detection of prostate lesions compared to the traditional model. Parameters estimated using the novel model at 1.5 T demonstrated high diagnostic performance in cancer lesion detection.

Summary: Radiomics provides an opportunity to uncover image-based biomarkers by converting and analyzing medical images into high-dimensional mineable data. However, the lack of a generally accepted analytic and reporting standard makes interstudy comparisons challenging. Comparing and combining results from multiple studies is essential for clinical application.

Summary: Evolution plays a crucial role in the initiation and progression of cancer. In addition to driver mutations, natural selection conserves genes that are necessary for optimal cancer cell fitness. By studying subtypes of lung adenocarcinoma, we identified highly mutated and highly conserved genes, which have common utility in adapting to similar tissue environments and are critical for optimal fitness. Targeting tumor-specific conserved genes may represent an effective treatment strategy.
