Article Abstract
Background: To research the first-order features of apparent diffusion coefficient (ADC) values on diffusion-weighted magnetic resonance imaging (DWI) in maxillofacial malignant mesenchymal tumours.
Methods: The clinical data of 12 patients with rare malignant mesenchymal tumours of the maxillofacial region (6 cases of sarcoma and 6 cases of lymphoma) treated in the hospital from May 2018 to June 2020 and were confirmed by postoperative pathology were retrospectively analyzed. The patients were all examined by 1.5T magnetic resonance imaging. PyRadiomics were used to extract radiomics imaging first-order features. Group differences in quantitative variables were examined using independent-samples t-tests.
Results: The voxels number of ADC and ADC of sarcoma tissues were 44.9124 and 44.2064, respectively, significantly higher than those in lymphoma tissues (ADC (- 68.8379) and ADC (- 74.0045)), the difference considered statistically significant, so do the ADC and ADC.
Conclusions: The statistical difference of ADC and ADC is significant, it is consistent with the outcome of the manual measurement of the ADC mean value of the most significant cross-section of twelve cases of lymphoma. Development of tumour volume based on the ADC parameter map of DWI demonstrates that the first-order ADC radiomics features analysis can provide new imaging markers for the differentiation of maxillofacial sarcoma and lymphoma. Therefore, first-order ADC features of ADC combined ADC may improve the diagnosis level.

Management of ocular toxicity in patients with gynecologic cancer receiving novel antibody-drug conjugates: a narrative review.

Ophthalmology Unit, Cannizzaro Hospital, 95126, Catania, Italy.
Antibody-drug conjugates (ADCs) represent a promising therapeutic approach in gynecologic cancers, particularly ovarian and cervical malignancies. Agents such as mirvetuximab soravtansine, and tisotumab vedotin, targeting folate receptor alpha and tissue factor, respectively, reported clinical efficacy in patients with limited options. However, their use is associated with ocular toxicities, including keratopathy, blurred vision, and dry eye, which may impact adherence and quality of life.

Purpose: In this retrospective study, whether [Ga]Ga-DOTA-FAPI-04 PET/MR imaging biomarkers can predict the progression-free survival (PFS) and overall survival (OS) of patients with advanced pancreatic cancer was investigated.
Methods: Fifty-one patients who underwent [Ga]Ga-DOTA-FAPI-04 PET/MR scans before first-line chemotherapy were recruited. Imaging biomarkers, including the maximum tumor diameter, minimum apparent diffusion coefficient (ADC), maximum and mean standardized uptake values (SUV and SUV), fibroblast activation protein- (FAP-) positive tumor volume (FTV and W-FTV) and total lesion FAP expression (TLF and W-TLF), were recorded for primary and whole-body tumors.
Enhanced Versus Standard Dermatologic Management With Amivantamab-Lazertinib in EGFR-Mutated Advanced NSCLC: The COCOON Global Randomized Controlled Trial.

Introduction: Amivantamab plus lazertinib significantly improved progression-free and overall survival versus osimertinib in patients with previously untreated, EGFR-mutant advanced NSCLC. EGFR-targeted therapies are associated with dermatologic adverse events (AEs), which can affect quality of life (QoL). COCOON was conducted to assess prophylactic management and improve treatment experience.

Objective: To evaluate multiparametric MRI features of pediatric soft-tissue sarcomas, comparing pre-treatment and post-treatment features, and assessing correlation with clinical outcomes.
Materials And Methods: Retrospective cohort study, including pediatric patients (≤ 18 years) with histologically-confirmed soft-tissue sarcomas who underwent MRI with anatomic and functional sequences in consecutive series. Post-treatment MRI was available for a subset, and features were recorded by two readers.
A vaccine emergency-when to overrule parental refusal of vaccination at birth for prevention of vertical transmission of hepatitis B virus?

Hepatitis B virus (HBV) is a potentially chronic infection that can be transmitted from mother to child with the risk of developing cirrhosis, liver failure and hepatocellular carcinoma. There is a safe and effective vaccine to prevent vertical transmission that is recommended to be given as soon as possible after birth and within 24 hours.When a woman with HBV refuses the birth dose of HBV vaccine for her baby, infectious diseases and safeguarding teams are asked to provide urgent opinions on whether this crosses the threshold for triggering child protection mechanisms.
