Small hepatocellular carcinoma is an important leading cause of death amongst cancer patients, our study was designed in order to test the hypothesis that radiofrequency ablation (RFA) combined with a chemotherapeutic drug would improve the outcome for patients. Two groups of patients presenting early small hepatocellular carcinoma were treated with either conventional RFA alone (50 individuals in the control group), or with a combination of RFA and oral sorafenib (40 individuals in an observation group). Individual clinical and laboratory evaluations were done during an average follow-up time of 35 months, and all the data recorded was used to compare results of both treatment approaches...

Canine spirocercosis is caused by the nematode Spirocerca lupi. Migration results in oesophageal fibro-inflammatory nodules that may undergo neoplastic transformation. No studies have assessed pre- or post-surgical prognostic indicators in dogs that undergo intervention for S. lupi induced oesophageal neoplasia. This observational, multi-center study aimed to assess the outcome of dogs with Spirocerca induced sarcoma undergoing endoscopic-guided ablation (n = 12) or surgery (n = 18), and identify prognostic indicators...

Surgical resection is the conventional therapeutic action for patients with an obstructive cardiac tumor. However, for patients in poor clinical condition, cardiac surgery can be risky. We report on the successful percutaneous radiofrequency (RF) ablation treatment of a right ventricular giant myxoma in a 70-year-old female with right ventricular outflow tract (RVOT) and pulmonary artery stenosis, who was unable to tolerate surgery. The treatment was effective in relieving RVOT stenosis and improving symptoms...

Nociceptive and/or neuropathic pain can be present in all phases of cancer (early and metastatic) and are not adequately treated in 56 to 82.3% of patients. In these patients, radiotherapy achieves overall pain responses (complete and partial responses combined) up to 60 and 61%. On the other hand, nowadays, ablation is included in clinical guidelines for bone metastases and the technique is governed by level I evidence. Depending on the location of the lesion in the peripheral skeleton, either the Mirels scoring or the Harrington (alternatively the Levy) grading system can be used for prophylactic fixation recommendation...

BACKGROUND: Treatment of cardiac arrhythmias often involves ablating viable muscle tissue within or near islands of scarred myocardium. Yet, today there are limited means by which the boundaries of such scars can be visualized during surgery and distinguished from the sites of acute injury caused by radiofrequency (RF) ablation. OBJECTIVE: We sought to explore a hyperspectral imaging (HSI) methodology to delineate and distinguish scar tissue from tissue injury caused by RF ablation...

BACKGROUND: Sarcomatoid hepatocellular carcinoma (SHC) is a rare malignant hepatic tumor. Recurrent interventional therapies such as transcatheter arterial chemo-embolization (TACE), radiofrequency ablation (RFA), and percutaneous ethanol injection have been reported previously utilized in a majority of SHC cases. To date, the exact pathogenic mechanisms underlying sarcomatoid transformation of hepatocellular carcinoma (HCC) remain unknown. CASE PRESENTATION: In this study, we report a 68-year-old female SHC patient admitted to our hospital due to discrete abdominal distention for more than 20 days...

Liver-directed therapy is a critical component of treatment strategies for hepatocellular carcinoma. These therapies included percutaneous image-guided ablation, transarterial chemoembolization, and transarterial radioembolization, and are administered by interventional radiologists. Depending on the stage of disease, a particular treatment modality, or a combination thereof, is expected to be most efficacious in achieving the goals of treatment for a particular patient. This article seeks to review the various liver-directed treatment modalities for treatment of hepatocellular carcinoma, with attention to their efficacy and patient selection criteria...
