BACKGROUND: Failure to locate lesions and accurately place microwave antennas can lead to incomplete tumor ablation. The Emprint™ SX Ablation Platform employs real-time 3D-electromagnetic spatial antenna tracking to generate intraoperative laparoscopic antenna guidance. We sought to determine whether Emprint™ SX affected time/accuracy of antenna-placement in a laparoscopic training model. METHODS: Targets (7-10 mm) were set in agar within a laparoscopic training device...

We conducted this retrospective study to investigate whether microwave ablation (MWA) of primary tumor sites plus epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) could improve survival in advanced non small cell lung cancer (NSCLC) with EGFR mutations. MWA was conducted at the primary tumor sites, followed by EGFR-TKIs in the MWA plus EGFR-TKIs group. EGFR-TKIs were administered until disease progression or intolerable toxicity. The primary endpoint was progression-free survival (PFS); secondary endpoints were overall survival (OS) and objective response rate (ORR)...

PURPOSE: In liver microwave ablation (MWA) surgery, the ablation area covers the tumor to generate tissue necrosis and treat the cancer. As the liver deforms during the operation, deviation between the target area determined during pre-operative planning and the resultant ablation area is inevitable. Therefore, an accurate assessment of tumor coverage is crucial for treatment. Through registration between the pre- and post-operative livers, the ablation area is warped on the pre-operative liver for the computation of tumor coverage...

Microwave ablation (MWA) is a promising minimally invasive therapy that has been widely used to treat hepatocellular carcinoma (HCC). However, the efficiency of MWA in treating HCC is evidently limited by the incomplete ablation of large tumors and tumors in high-risk locations. Here, we report the value of using liposomes packed with sodium chloride (NaCl-LPs) as effective thermo-seeds for MWA of HCC. The prepared liposomes exhibited excellent heat conversion ability by showing a more rapid temperature increase than free NaCl medium, blank liposomes or water under microwave irradiation...

BACKGROUND: The standard treatment of T1 renal cell carcinoma (RCC) is (partial) nephrectomy. For patients where surgery is not the treatment of choice, for example in the elderly, in case of severe comorbidity, inoperability, or refusal of surgery, alternative treatment options are available. These treatment options include active surveillance (AS), radiofrequency ablation (RFA), cryoablation (CA), microwave ablation (MWA), or stereotactic body radiotherapy (SBRT). In the present overview, the efficacy, safety, and outcome of these different options are summarized, particularly focusing on recent developments...

AIMS/HYPOTHESIS: Retinal imaging enables non-invasive microvasculature assessment; however, only central retinal vessels have been studied in type 1 diabetes. Peripheral smaller vessels have a major haemodynamic role and may differ from central vessels in their response to the diabetic milieu. We hypothesise that diabetes has a greater impact on peripheral retinal vessels vs central vessels. METHODS: Retinal photographs from adolescents (n = 736; age 12-20 years) with type 1 diabetes were graded (Singapore I Vessel Assessment) with vessel calibres measured in the 'central zone' as central retinal arteriolar and venular equivalents (CRAE and CRVE, respectively) and the 'extended zone' as mean width of arterioles and venules (MWa and MWv, respectively)...
