Article Synopsis
  • Liver resection can lead to complete remission in patients with advanced liver cancer, but its extra benefits after tumor downstaging haven't been fully explored.
  • A study analyzed data from 999 patients who received treatment for liver cancer, comparing those who had liver surgery with those who did not, to see if surgery improved long-term outcomes.
  • Results indicated that both groups had similar long-term survival rates, suggesting that liver resection may not offer additional benefits for patients expected to have complete necrosis after treatment.

Objective: Radiation necrosis is becoming an increasingly prevalent complication in patients with brain tumors given the growing utility of stereotactic radiosurgery in modern treatment paradigms. Magnetic resonance-guided laser interstitial thermal therapy (MRgLITT) is a new minimally invasive modality that has exhibited an efficacy comparable to craniotomy in treating radiation necrosis. No studies to date have compared their cost-effectiveness despite the significant additional expenses associated with MRgLITT use.

Photodynamic therapy (PDT) is an alternative to cancer treatment, demonstrating selectivity and significant cytotoxicity on malignant tissues. Such therapy involves two nontoxic components: photosensitizer (PS) and non-ionizing radiation. In optimal dosage combinations, PDT causes cellular and tissue effects by oxygen-dependent processes, leading tumor cells to regulated cell death pathways.

Background And Purpose: We aimed to determine if ultra-hypofractionated radiotherapy (UHYPO-RT) delivering 6Gy x 5 fractions yields similar tumour necrosis compared to conventional radiotherapy (CONV-RT) with 2Gy x 25 fractions in soft tissue sarcoma (STS). The clinical significance of tumor necrosis on loco-regional recurrence-free survival (LRFS), distant disease-free survival (DDFS), and overall survival (OS) were assessed.

Materials And Methods: Patients with localised STS treated with CONV-RT or UHYPO-RT followed by surgery were included.

October 2024

Department of Radiation Oncology, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, Zhejiang, 325000, China.

Article Synopsis
  • The study investigated how apparent diffusion coefficient (ADC) values from MRI can predict survival in glioma patients before surgery.
  • It involved a retrospective analysis of 101 patients, categorizing tissue types (parenchyma, peritumoral area, and necrosis/cysts) and using COX regression for data analysis.
  • Findings indicated that higher ADC values and specific biomarkers (Ki67, P53, IDH) correlate with longer disease-free and overall survival, making ADC values a useful predictor for glioma patient outcomes.

Antiresorptive therapy in combination with radiation results in enhanced risk for necrosis and associated complicatifions.

Oral Surg Oral Med Oral Pathol Oral Radiol

January 2025

Department of Oral and Maxillofacial Surgery and Facial Plastic Surgery, University Hospital, LMU Munich, Germany.

Article Synopsis
  • Patients treated with both antiresorptive medication and radiotherapy in the head and neck are at increased risk for developing complications such as jaw necrosis, fractures, and recurrence of conditions.
  • The study involved 17 patients who were compared to larger control groups, revealing significant differences in outcomes, with those receiving combined treatment facing higher risks.
  • The findings suggest that the combination of these treatments leads to a four-fold increase in recurrence risk and a higher likelihood of serious complications compared to patients receiving just one type of treatment.

In this study, we demonstrated the mechanism of a glioblastoma (GBM)-targeted sonodynamic therapy (SDT) strategy employing platelets loaded with a sonosensitizer based on functionalized boron nitride nanoparticles carrying chlorin e6 (BNPD-Ce6). In the in vitro study, we first found that the BNPD-Ce6-mediated sonodynamic action (SDA) induced remarkable viability loss, DNA damage, and cell death in the GBM cells (GBCs) but not macrophages. Surprisingly, the SDA-exposed GBCs displayed a ferroptotic phenotype while the SDA-exposed macrophages underwent immuno-stimulatory autophagy and potently potentiated the SDA's toxicity to the GBCs.

Tropical rainforests are hot and may be particularly sensitive to ongoing anthropogenic global warming. This has led to increased interest in the thermotolerance of tropical trees. Thermotolerance of leaves of two tropical tree species, Terminalia catappa and Coccoloba uvifera, was determined by exposing leaf samples to 15-min heat treatments, followed by measurements of potential photosystem II quantum yield (dark-adapted value of variable/maximum chlorophyll a fluorescence, F/F) after 24 h and 14 days, and visible damage (necrosis) after 14 days.

Article Synopsis
  • - Cancer is the second leading cause of death globally, and about 50% of patients receive radiation therapy, predominantly photon radiation, despite advancements in proton radiation therapy (PBT) that aims to minimize damage to healthy tissue.
  • - Proton therapy utilizes the Bragg peak property of protons to deliver targeted radiation with potentially lower toxicity compared to photon therapy, but patients may still experience proton-specific side effects.
  • - Reported toxicities from proton therapy include issues related to the brain, lungs, heart, gastrointestinal system, and genitourinary system; while similar to those from photon therapy, they generally occur less frequently.

Human monocytes can be subdivided into phenotypically and functionally different classical, intermediate and non-classical monocytes according to the cell surface expression of CD14 and CD16. A precise identification and characterisation of monocyte subsets is necessary to unravel their role in inflammatory diseases. Here, we compared three different flow cytometric strategies (A-C) and found that strategy C, which included staining against CD11b, HLA-DR, CD14 and CD16, followed by several gating steps, most reliably identified monocyte subtypes in blood samples from healthy volunteers and from patients with stable coronary heart disease (CHD) or ST-elevation myocardial infarction (STEMI).

Cancer-associated macrophage-like cells (CAMLs) are rare, gigantic, and atypical circulating cells found exclusively in the peripheral blood of patients with solid cancers. Obesity-induced hypoxia attracts macrophages to the tumor microenvironment, where they contribute to establishing chronic inflammation, leading to cancer progression. We hypothesized that obese patients with advanced breast cancer may have CAML profiles different from those of nonobese patients, and these profiles may correlate with proinflammatory markers or other macrophage-related markers.
