Aim: The aim of this study was to investigate if Linomide affects growth and spread of a rat liver tumour when given alone and in combination with interstitial laser thermotherapy (ILT).
Materials And Methods: Experiments were performed in Wistar rats using a dimethyl-hydrazine-induced adenocarcinoma implanted into the left lateral lobe of the liver. The rats were randomised to one of the following groups: a) ILT and Linomide, b) ILT only, c) sham ILT, d) Linomide only, or e) control. ILT was intentionally suboptimal. Linomide (100 mg/kg/day) was given in the drinking water from the start of treatment for five days. ED1, ED2 macrophages and v Willebrand (factor VIII) were determined by an immunohistochemical technique.
Results: Linomide reduced viable liver tumour volume both when it was given alone (p < 0.01) and when combined with ILT (p < 0.05), whereas it lowered intraperitoneal spread in ILT-treated rats alone. Six days after ILT, there was a reduction in the number of newly-recruited macrophages and blood vessels in the viable tumour tissue in rats receiving Linomide.
Conclusion: Linomide reduced the growth of an adenocarcinoma transplanted into rat liver, when given alone or combined with laser thermotherapy and reduced the spread of tumour in laser-treated rats. The effects of Linomide in laser-treated rats appeared, at least in part, to be due to a reduction in newly-formed vessels, which might have been secondary to a reduced number of tumour-associated macrophages.

Bioenergetic therapy based on tumor glucose metabolism is emerging as a promising therapeutic modality. To overcome the poor bioavailability and toxicity of arenobufagin (ArBu), a MOF-derived intelligent nanosystem, ZIAMH, was designed to facilitate energy deprivation by simultaneous interventions of glycolysis, OXPHOS and TCA cycle. Herein, zeolitic imidazolate framework-8 was loaded with ArBu and indocyanine green, encapsulated within metal-phenolic networks for chemodynamic therapy and hyaluronic acid modification for tumor targeting.

Reactive oxygen species (ROS)-mediated anticancer modalities, which disturb the redox balance of cancer cells through multi-pathway simulations, hold great promise for effective cancer management. Among these, cooperative physical and biochemical activation strategies have attracted increasing attention because of their spatiotemporal controllability, low toxicity, and high therapeutic efficacy. Herein, we demonstrate a nanogel complex as a multilevel ROS-producing system by integrating chloroperoxidase (CPO) into gold nanorod (AuNR)-based nanogels (ANGs) for cascade-amplifying photothermal-enzymatic synergistic tumor therapy.

Introduction: Water vapor thermal therapy (WVTT; REZUM™; Boston, USA) offers symptom relief with reduced risks of complications in patients with lower urinary tract symptoms (LUTS) related to benign prostatic obstruction (BPO). WVTT therapy has been validated in the pivotal study in men with smaller prostates (< 80 cc). Yet, its feasibility for larger prostates (≥ 80 cc) remains underexplored.

Purpose: A synergistic treatment strategy of phototherapy and chemotherapy has been shown to improve efficacy and offer unique advantages over monotherapy. The purpose of this study is to explore a new nanocarrier system with liposome as the inner membrane and erythrocyte membrane as the outer membrane, which aims to realize the leak-free load of phototherapy drug indocyanine green (ICG) and chemotherapy drug doxorubicin (DOX), prolong the circulation time in vivo and improve the therapeutic effect.
Patients And Methods: In this study, bilayer membrane-loaded ICG and DOX nanoparticles (RBC@ICG-DOX NPs) were prepared and characterized.

We conducted a systematic review to compile the findings of all published studies on the use of percutaneous laser ablation (PLA) in the treatment of early-stage breast cancer. We aimed to identify appropriate methodology as well as parameters for the selection of suitable patients to optimize outcomes with the use of PLA. Additionally, we aimed to analyze whether this method is a viable alternative to current surgical treatments employed.
