Introduction: Craniopharyngiomas are challenging benign tumors arising from Rathke's pouch remnants, often requiring multidisciplinary management due to their proximity to critical neurovascular structures. This meta-analysis systematically compares conventional radiation therapy (RT) and stereotactic radiosurgery (RS) in treating residual or recurrent craniopharyngiomas.
Method: A comprehensive literature search identified 44 studies, including 46 reports, meeting inclusion criteria such as progression-free survival (PFS) and post-radiotherapy complications. Data extraction followed PRISMA guidelines.
Results: The pooled 5-year PFS favored RT (0.843; 95% CI: 0.767-0.898) over RS (0.680; 95% CI: 0.631-0.727), as did 10-year PFS (RT: 0.813; 95% CI: 0.683-0.888; RS: 0.553; 95% CI: 0.470-0.634). RT demonstrated mitigating tumor recurrence risks. Visual and hormonal complication rates between the modalities were comparable (visual: ~4%; hormonal: ~6%).
Conclusion: RT consistently achieved superior long-term PFS compared to RS, reaffirming its role as the standard for adjuvant therapy in craniopharyngiomas. This analysis highlights the need for tailored treatment strategies balancing efficacy and safety, ultimately enhancing patient outcomes.

Although radiotherapy techniques are the primary treatment for head and neck cancer (HNC), they are still associated with substantial toxicity, and side effect. Machine learning (ML) based radiomics models for predicting toxicity mostly rely on features extracted from pre-treatment imaging data. This study aims to compare different models in predicting radiation-induced xerostomia and sticky saliva in both early and late stage of HNC patients using CT and MRI image features along with demographics and dosimetric information.

To undertake a mixed-methodology implementation study to improve the well-being of men with gastrointestinal late effects following radical radiotherapy for prostate cancer. All men completed a validated screening tool for late bowel effects (ALERT-B) and the Gastrointestinal Symptom Rating Score (GSRS); men with a positive score on ALERT-B were offered management following a peer reviewed algorithm for pelvic radiation disease (PRD). Health-related quality of life (HRQoL) at baseline, 6 and 12 months; and healthcare resource usage (HRU) and patient, support-giver, staff experience and acceptability of staff training (qualitative analysis) were assessed.

Radio-immunotherapy has antitumor activity but also causes toxicity, which limits its clinical application. JS-201 is a dual antibody targeting PD-1 and TGF-β signaling. We investigated the antitumour effect of JS-201 combined with radiotherapy and the effect on radiation-induced lung injury (RILI).

Background: Cell therapy demonstrates promising potential as a substitute therapeutic approach for liver cirrhosis. We have developed a strategy to effectively expand murine and human hepatocyte-derived liver progenitor-like cells (HepLPCs) in vitro. The primary objective of the present study was to apply HepLPCs to the treatment of liver cirrhosis and to elucidate the underlying mechanisms responsible for their therapeutic efficacy.
