Between June 2006 and January 2016, 6 renal cryoablation procedures were performed in 5 patients with horseshoe kidneys. Renal cell carcinoma (RCC) accounted for 5 of the tumors, and the sixth was a carcinoid tumor. All 6 procedures were technically successful. The patient with the carcinoid tumor developed local tumor progression 38 months after ablation. Technique effectiveness was achieved in all 5 patients with RCC. Two complications occurred: obstructive hematuria and transient inguinal neuralgia after ablation...

Absolute lymphocyte count (ALC) recovery rapidly occurring at 14 days after start of chemotherapy for osteosarcoma and Ewing sarcoma is a good prognostic factor. Conversely, lymphopenia is associated with significantly decreased sarcoma survival. Clearly, the immune system can contribute towards better survival from sarcoma. This chapter will describe treatment and host factors that influence immune function and how effective local control and systemic interventions of sarcoma therapy can cause inflammation and/or immune suppression but are currently the standard of care...

CASE DESCRIPTION A 9-year-old spayed female Rottweiler with hind limb ataxia was examined because of anorexia and an acute onset of hind limb paresis. CLINICAL FINDINGS Neurologic evaluation revealed hind limb ataxia and symmetric paraparesis with bilaterally abnormal hind limb postural reactions including hopping, hemiwalking, hemistanding, and delayed proprioception, which were suggestive of a lesion somewhere in the T3-L3 segment of the spinal cord. Thoracolumbar radiography revealed an abnormal radiopacity suggestive of a mass at T11...

Neuropathy of the posterior femoral cutaneous nerve may manifest as pain and paresthesia in the skin over the inferior buttocks, posterior thigh, and popliteal region. Current treatment options include physical and oral pain therapy, perineural injections, and surgical neurectomy. Perineural steroid injections may provide short-term pain relief; however, to our knowledge, there is currently no minimally invasive denervation procedure for sustained pain relief that could serve as an alternative to surgical neurectomy...

In this study, the clinical efficacy of cryosurgery combined with allogenic NK cell immunotherapy for advanced renal cell cancer was evaluated. From July to December 2016, we enrolled 60 patients who met the enrollment criteria and divided them into two groups: (1) the simple cryoablation group (n=30); and (2) the cryoablation combined with allogenic NK cells group (n=30). The clinical efficacy, quality of life, immune function, and other related indicators were evaluated. Combining allogeneic NK cells with cryoablation had a synergistic effect, not only enhancing the immune function and improving the quality of life of the patients, but also significantly exhibiting good clinical efficacy of the patients...

BACKGROUND: Catheter ablation has become the first line of therapy in patients with symptomatic, recurrent, drug-refractory atrial fibrillation (AF). Cryoablation has been shown to be a safe and effective technique for pulmonary vein (PV) isolation. However, the arrhythmia recurrence rate is high after cryoablation procedures. Radiofrequency catheter ablation has been shown to be an effective strategy for redo procedures in these patients and to provide a favourable outcome during midterm follow-up...

The European Society for Medical Oncology (ESMO) have stressed that the option for treating oligometastatic disease is a strategy of local ablative therapy, the goal of which is to improve disease control. The spectrum of the local ablative therapy toolbox described by the ESMO includes surgical R0 resection, percutaneous ablation and intra-arterial therapies, the choice of treatment being left to the multidisciplinary team. Interventional therapy involving image-guided treatment offers the possibility of less invasive treatments for colorectal cancer metastases in the liver, lung and bone by preserving from toxicity distant healthy organs or even parts of the diseased organs...

The increased use of abdominal imaging has led to a major increase in small renal tumors incidence particularly in the elderly population. Their management is evolving with the development of percutaneous ablation, particularly radiofrequency ablation, cryoablation, and microwave ablation. The typical indications that must be validated by a multidisciplinary committee include solid tumors less than 3cm in patients with multiple comorbidity factors (including age), contraindications to surgery, hereditary renal cancer, bilateral renal tumors, solitary kidney, pre-existing chronic kidney disease, or at high risk of predialysis renal function after partial nephrectomy...

BACKGROUND: Cryoablation for paroxysmal atrial fibrillation (PAF) is well established. The single-big-balloon strategy has been preferred for pulmonary vein isolation (PVI) using the second generation cryoballoon (CBG2). Individual PV-morphologies raise the question if an individualized anatomic approach using the 23-mm or 28-mm CB is reasonable. METHODS: Consecutive patients were prospectively enrolled in the non-randomized single-center study. Patients were treated with the 28-mm CB, if any PV was >21mm, the 23-mm CB, if all PV were ≤21mm, or both sizes, if PVI was difficult...

Today, in addition to surgery, other local therapies are available for patients with small-size non-small-cell lung cancer (NSCLC) and oligometastatic disease from various cancers. Local therapies include stereotactic ablation radiotherapy (SABR) and thermal ablative therapies through percutaneously inserted applicators. Although radiofrequency ablation (RFA) has been explored in series with several hundreds of patients with pulmonary tumours, investigation of the potential of other ablation technologies including microwave ablation, cryoablation, and irreversible electroporation is ongoing...
