Abstract Cancer has and continues to be a complex health crisis plaguing millions around the world. Alcohol ablation was one of initial methods used for treatment liver lesions. It surpassed by thermal which played big role in therapeutic arsenal primary metastatic tumors. However, several shortcomings limitations that prompted development alternative technologies including electroporation histotripsy. Percutaneous alcohol injection lesion leads dehydration coagulative necrosis. This technology is limited with relative sparing surrounding tissue, making it safe use adjacent sensitive structures. Electroporation utilizes short high-voltage pulses permeabilize cell membrane can result death dependent on threshold reached. effectively target tumor margins lower damage rates structures due pulse duration. Histotripsy novel technology, although first human trial just completed, its results are encouraging, given sharp demarcation targeted lack damage, potential immunomodulation microenvironment. Herein, we discuss these techniques, their uses, overall clinical benefit.

Hyperthermia, the raising of tumor temperature (≥39°C), holds great promise as an adjuvant treatment for cancer therapy. This review focuses on 2 key aspects hyperthermia: its molecular and cellular effects impact immune system. Hyperthermia has profound critical biological processes. Increased temperatures inhibit DNA repair enzymes, making cells more sensitive to chemotherapy radiation. Elevated also induce cell cycle arrest trigger apoptotic pathways. Furthermore, hyperthermia modifies expression heat shock proteins, which play vital roles in therapy, including enhancing responses. Hyperthermic treatments have a significant body’s response against tumors, potentially improving efficacy checkpoint inhibitors. Mild systemic (39°C-41°C) mimics fever, activating metabolic rates. Intense above 50°C can release antigens, reactions. Using photothermal nanoparticles targeted heating drug delivery modulate response. emerges cost-effective well-tolerated therapy when integrated with immunotherapy. comprehensive serves valuable resource selection patient-specific guidance future experimental studies.

Colorectal cancer (CRC) remains one of the leading causes cancer-related morbidity and mortality around world. Despite advances in surgery, chemotherapy, targeted therapies, prognosis for patients with metastatic or advanced CRC poor. Immunotherapies comprising immune checkpoint inhibitors showed disappointing responses (mCRC). However, cellular immunotherapy, specifically using classical dendritic cells (cDCs), may hold unique promise recognition antigens. cDCs are substantial players instrumental orchestrating innate adaptive by processing presenting tumor antigens to effector cells. Natural killer T (NKT) insufficiently studied but because their ability bridge reactions crosstalk cancer. This review explores therapeutic potential both NKT as a synergistic therapy CRC, focusing on biological roles, strategies harnessing capabilities, clinical applications, challenges within microenvironment. Both can be used new effective approach cell-based therapies cancers provide hope that challenging treat.

Purpose In magnetic resonance-guided focused ultrasound (MRgFUS) breast therapies, the focal location must be characterized to guide successful treatment. Focal characterization is difficult because heterogeneous tissues introduce phase aberrations that blur and shift focus traditional guidance methods do not work in adipose tissues. The purpose of this evaluate numerical simulations MRgFUS predict location. Those are compared clinical resonance acoustic radiation force imaging (MR-ARFI) data collected during vivo treatment tumors.

Immune checkpoint inhibitors hold promise, yet their efficacy in solid tumors is limited by the complex tumor microenvironment and lack of immune cell infiltration. This study aims to enhance immunotherapy combining anti PD-1 inhibition therapy with nanodroplet-mediated histotripsy. The proposed method involves systemic injection nanodroplets, which accumulate within tumors. These nanodroplets are then activated into cavitating gas bubbles using a rotating imaging probe, followed low-frequency ultrasound application. process induces fractionation, facilitating shift from cold hot. Tumor ablation results show extensive lesions cancerous tissues, demonstrating effectiveness treatment. combined approach yielded significant reduction growth compared control groups. Immunohistochemistry analysis reveals an increase F4/80+ macrophages CD8+ T cells treated group, indicating enhanced response. reached 21.36% ± 3.4%, while T-cell recruitment achieved 6.76% 4.5%, representing 6.8- 5.5-fold respectively. demonstrates potential overcome key barriers treatment precise mechanical disruption activation.

Physical approaches based on irradiation provide advances for the prevention and treatment of viral infections, while recognizing that certain chemical inactivation techniques demonstrate significant effectiveness alongside physical methods. By generating resonant vibrations complete virus particles, which are in GHz range quite high compared to human cells, viruses can be inactivated. Therefore, exposure ultrasound waves or non-thermal microwaves with a suitable frequency oscillating electric field holds potential neutralize particle no damage human. The deactivation mechanism could result mechanical effect oxidation stress, this article, we discuss elucidation these effects virus' structure. We also explore current state future prospects anti-viral methods acoustic cavitation via microwave, addressing critical needs virology.

Glioblastoma (GBM) is the most common and malignant type of primary brain tumor. Even after surgery chemoradiotherapy, residual GBM cells can infiltrate healthy parenchyma to form secondary tumors. To mitigate recurrence, we recently developed an injectable hydrogel that be crosslinked in resection cavity attract, collect, ablate cells. We previously optimized a thiol-Michael addition for physical, chemical, biological compatibility with microenvironment demonstrated CXCL12-mediated chemotaxis attract entrap into this hydrogel. In study, synthesize hydrogels under conditions mimicking cavities assess feasibility histotripsy hydrogel-encapsulated The results showed synthesis was bio-orthogonal, not shear-thinning, scaled up injection mimics vitro. Experiments also ultrasound imaging distinguish synthetic from porcine tissue. Finally, 500 kHz transducer applied focused treatment hydrogels, demonstrating precise bubble clouds could sustained order uniformly red blood encapsulated by homogeneous, mechanical fractionation entrapped Overall, promising platform biomaterials-based treatment.

Objective Brain tumors represent some of the most treatment refractory cancers, and there is a clinical need for additional treatments these tumors. Domesticated dogs are only other mammalian species which commonly develop spontaneous brain tumors, making them an ideal model investigating novel therapies. Histotripsy non-thermal ultrasonic ablation method that emulsifies tissue through acoustic cavitation. The primary objectives this prospective study were to assess feasibility safety histotripsy ablate naturally occurring canine Secondary endpoints included characterization magnetic resonance imaging (MRI) responses treatment, exploratory immunogenomic tumor response analyses. Methods design utilized treat resect paradigm, where approached using craniotomy, partially ablated with delivered cranial defect, imaged MRI, then resected. Dogs evaluated clinical, immunopathologic, genomic examinations before intraoperatively, 1, 14, 42 days post-treatment. Here we report results three meningiomas, all treated custom eight element 1 MHz transducer at pulse repetition frequency 100 Hz dosage 400 pulses/point. Results was successfully dogs, resulting in histopathologic evidence ablations sharply demarcated from untreated tumor, measured approximating planned volumes 2/3 dogs. One dog experienced adverse event consisting transient cerebral edema possibly attributable histotripsy. could be grossly visualized identified on features consistent hemorrhage necrosis. Significant expression or upregulation damage associated molecular pattern HMGB1, cytokine-cytokine receptor interaction, NF-κb signaling pathways observed Conclusion Ablation meningiomas open window feasible clinically well tolerated.
