The current state and future perspectives of high intensity focused ultrasound (HIFU) ablation for benign thyroid nodules.

ABSTRACT: High intensity focused ultrasound (HIFU) is a new thermoablation technique used to treat benign thyroid nodules. In this method, the ultrasound beam passes through the patient's skin and focuses very precisely on the target lesion at a distance far from the source of ultrasound generation, making HIFU the only truly non-invasive method of thermoablation developed to date. HIFU is therefore an attractive alternative to surgery and other thermoablative techniques. This review describes the principles of HIFU treatment, the selection of patients suitable for HIFU, the course and effects of treatment, and future perspectives.

The efficacy and safety of high-intensity focused ultrasound ablation of benign thyroid nodules.

Project description:High-intensity focused ultrasound (HIFU) is a promising form of thermal ablation of benign thyroid nodules, but evidence supporting its use is scarce. The present review evaluated the efficacy and safety of single-session HIFU treatment of benign thyroid nodules. As reported in the literature, the extent of nodule shrinkage following treatment ranged from 48.8% to 68.8%. Like other forms of ablation, the shrinkage rate was greatest in the first 3-6 months, and the best responders were patients with small (?10 mL) nodules. Complications were uncommon, but temporary vocal cord palsy occurred in 3%-4% of patients, and was related to the distance between the HIFU beam and the recurrent laryngeal nerve. Despite being safe and efficacious, a larger-scale prospective trial is required.

Early assessment of high-intensity focused ultrasound treatment of benign thyroid nodules by scintigraphic means.

Project description:BackgroundHigh-intensity focused ultrasound (HIFU) allows to inflict intracorporal thermal lesions without penetrating the skin or damaging the surrounding tissue. This analysis intends to assess the magnitude of HIFU-induced ablations within benign thyroid nodules using scintigraphic imaging with (99m)Tc.MethodsTen cold, hot, or indifferent nodules were treated using multiple pulses of HIFU to induce temperatures of around 85°C within the ablation zone. Pre- and posttreatment, uptake values of (99m)Tc-pertechnetate or (99m)Tc-MIBI were recorded. The pre-post reduction of nodular uptake was evaluated to assess ablation magnitude.ResultsRelative nodular uptake in relation to total thyroidal uptake decreased after one session of HIFU in all cases. Median (99m)Tc-MIBI uptake reduction was 35.5% (ranging from 11% to 57%; p < 0.1), while (99m)Tc-pertechnetate scintigraphy showed a median uptake reduction of 27% (range 10% to 44%; p < 0.1). No major complications were observed.ConclusionsHIFU appears to be safe and is an easy to perform means of thermal ablation. This study shows that HIFU treatment in thyroidal nodules can be evaluated by scintigraphic means shortly after the intervention. Due to small sample size, the exact magnitude of HIFU ablation efficiency in thyroidal nodules remains a value to be assessed in a larger study.

Ultrasound-guided radiofrequency ablation (RFA) of benign symptomatic thyroid nodules - initial UK experience.

Project description:OBJECTIVE:To report on the use of RFA for the treatment of symptomatic benign and autonomously functioning thyroid nodules (AFTNs) in the first reported UK cohort. METHODS:Patients treated over a 19-month period were retrospectively reviewed. Nodules were assessed pre-treatment and at 1 and 6?months post-treatment. Nodule volume was calculated and cosmetic assessment and thyroid-related quality of life (QoL) scores were recorded at each time point. Thyroid function tests (TFTs) were recorded at all three time points for patients with ATFNs. RESULTS:46 patients with 50 nodules were treated with no complications. The mean volume reduction 1-month post-treatment was 53 +- 14.9 % ( p < 0.0001). Six month data was available for 31 nodules and showed a mean 67 +- 17.6%?vol reduction ( p < 0.0001). Five of the six patients with ATFNs were euthyroid at 1-month post-procedure. 6-month data was available on three of these patients, and all remained euthyroid. The thyroid-related QoL and cosmetic scores also improved. Data from 23 patients was available pre-treatment and at 6?months post-treatment and there was a significant ( p < 0.0001) reduction in QoL score. Pre-treatment, 82 % of nodules were readily visible at rest, decreasing to 12.5 % 6 months after treatment ( p < 0.0001). CONCLUSIONS:Results align with published data suggesting that RFA is effective at reducing nodule volume and at treating ATFNs and leads to improvement in thyroid-related QoL and cosmetic scores. ADVANCES IN KNOWLEDGE:This early UK experience demonstrates that day-case radiofrequency ablation can provide safe and effective treatment of benign symptomatic thyroid nodules.

Evaluation of post-ablation mpMRI as a predictor of residual prostate cancer after focal high intensity focused ultrasound (HIFU) ablation.

Project description:PurposeTo evaluate the performance of multiparametric magnetic resonance imaging (mpMRI) and PSA testing in follow-up after high intensity focused ultrasound (HIFU) focal therapy for localized prostate cancer.MethodsA total of 73 men with localized prostate cancer were prospectively enrolled and underwent focal HIFU followed by per-protocol PSA and mpMRI with systematic plus targeted biopsies at 12 months after treatment. We evaluated the association between post-treatment mpMRI and PSA with disease persistence on the post-ablation biopsy. We also assessed post-treatment functional and oncological outcomes.ResultsMedian age was 69 years (Interquartile Range (IQR): 66-74) and median PSA was 6.9 ng/dL (IQR: 5.3-9.9). Of 19 men with persistent GG ≥ 2 disease, 58% (11 men) had no visible lesions on MRI. In the 14 men with PIRADS 4 or 5 lesions, 7 (50%) had either no cancer or GG 1 cancer at biopsy. Men with false negative mpMRI findings had higher PSA density (0.16 vs. 0.07 ng/mL2, P = 0.01). No change occurred in the mean Sexual Health Inventory for Men (SHIM) survey scores (17.0 at baseline vs. 17.7 post-treatment, P = 0.75) or International Prostate Symptom Score (IPSS) (8.1 at baseline vs. 7.7 at 24 months, P = 0.81) after treatment.ConclusionsPersistent GG ≥ 2 cancer may occur after focal HIFU. mpMRI alone without confirmatory biopsy may be insufficient to rule out residual cancer, especially in patients with higher PSA density. Our study also validates previously published studies demonstrating preservation of urinary and sexual function after HIFU treatment.

Image-guided thermal ablation of benign thyroid nodules.

Project description:Purpose:To clarify some relevant and significant inconsistencies and inaccuracies in review by Mainini et al. entitled "Image-guided thermal ablation of benign thyroid nodules" published in Journal of Ultrasound to avoid giving incorrect information to the reader and prevent that operators make wrong choices in the use of various devices and technologies available. Results:Total cases treated with radiofrequency would be 2388 and not 2435 as reported in Table 1 of this review. The major, minor complications, and side effects in the partial group treated with laser technique and reported in this review are actually 1.2, 3.8, and 35.4%, respectively. In series of patients treated with laser ablation, including a total of 2345 patients, major and minor complications are 0.7 and 1.4%, respectively. The major complications of laser technology are less severe than RFA. Conclusions:Several points regarding the paper by Mainini et al. need to be discussed, and I advocate authors for replying to my considerations to clarify the issues raised.

Ultrasound-Guided Percutaneous Microwave Ablation for Solid Benign Thyroid Nodules: Comparison of MWA versus Control Group.

Project description:Background:The aim of this research is to investigate the feasibility of percutaneous ultrasound-guided microwave ablation (MWA) for benign solid thyroid nodules. Methods:Ultrasound-guided percutaneous microwave ablation was performed for 90 benign solid thyroid nodules in 75 patients. The volume changes of the nodules were evaluated before and after microwave ablation, and the cosmetic grading and clinical symptoms were assessed as well. Results:The volume of all the 90 benign thyroid nodules obviously decreased after microwave ablation at 3-, 6-, 9-, and 12-month follow-ups (p < 0.01), while that of the control group increased at the follow-up of 12 months (p < 0.01). The volume reduction rate (VRR) at 3-, 6-, 9-, and 12-month follow-ups was 55.98%, 69.31%, 76.65%, and 84.67% in the MWA group, respectively. The cosmetic problems and clinical symptoms were also improved in the MWA group. All the patients are well tolerated to the procedure. Hoarseness occurred in 2 cases (2.7%) and Horner syndrome in 1 case (1.3%), and 1 patient (1.3%) developed slight burn on cervical skin. Conclusions:Ultrasound-guided percutaneous microwave ablation is a practical method for treating benign solid thyroid nodules, and the complications were acceptable. The trial is registered with clinicaltrials.gov with the registration number NCT03057925.

Stages of benign thyroid nodules: principles and ultrasound signs.

Project description:Benign thyroid nodules are significantly common and occur in 50-60% of the population. Therefore, differentiation from malignant nodes and the choice of treatment tactics in some cases of benign pathology remain relevant. Despite advances in the clinical evaluation of thyroid nodules, methodological challenges exist due to empirically simplistic understandings of the nodular process. Different opinions on the pathogenesis of thyroid nodules and the history of the formation of the idea of the stages of nodules are considered. For the first time, based on natural principles and many years of ultrasound analysis of changes in benign thyroid nodules, three stages of the nodular process were identified: Development, Wasting and Scarring. The stage of exhaustion has three substages: Initial, Moderate and Significant Wasting. The principles of stage-by-stage changes in nodules are explained and their ultrasound signs are shown. The key principle of the stages of nodules is the ratio of the magnitudes of the processes of regeneration (proliferation) and destruction in the nodule. Separate stage changes may occur in node segments. In such cases, part of the segments may show signs of the Development stage, another part-Wasting, and the third part-Scarring. The different variants of thyroid nodules are explained in terms of stages. Practical recommendations for differentiating ultrasound signs of nodules associated with stages are proposed. Knowledge about the staged changes in thyroid nodules helps reduce the likelihood of diagnostic errors, better navigate the prognosis and choice of treatment tactics, and recommend preventive ultrasound examination of the thyroid.

Percutaneous laser ablation for benign thyroid nodules: a meta-analysis.

Project description:PurposeTo evaluate percutaneous laser ablation in treating benign thyroid nodules, we conducted a meta-analysis based on summarizing existing researches.Materials and methodsA literature search for clinical trial was performed in PubMed, Cochrane Library and Excerpt Medica Database. The qualities of included studies were evaluated. We calculated the indexes with mean difference. Heterogeneity and publication bias were tested and explored. We performed subgroup analyses and sensitivity analysis further.ResultsA total of 19 researches and 2137 patients were included in this meta-analysis. The pooled estimates of nodule volume were statistically significant after percutaneous laser ablation for 1 month, 3 month, 6month, 12month, 24month and 36month(P < 0.05). The pooled estimate of thyroid-stimulating hormone was statistically significant after percutaneous laser ablation for 1 and 12 month (P = 0.008 and P = 0.03). The pooled estimate of free triiodothyronine was no statistically significant after percutaneous laser ablation for all follow-up intervals. The pooled estimate of free tetraiodothyronin was statistically significant after percutaneous laser ablation1 month (P = 0.004). The pooled estimate of thyroglobulin was statistically significant after percutaneous laser ablation 24 month (P = 0.04). The heterogeneity was found and the source of heterogeneity was explored in nodule volume for 6 and 12 month. No publication bias was found.ConclusionsThis meta-analysis demonstrated that percutaneous laser ablation was safe and useful in shrinking benign thyroid nodules volume, improving thyroid function, relieving symptoms of pressure and esthetic, especial for hyper-vascular benign thyroid nodules. Larger number of high-quality prospective studies still needs to be performed.

Cetuximab-conjugated perfluorohexane/gold nanoparticles for low intensity focused ultrasound diagnosis ablation of thyroid cancer treatment.

Project description:We report the formulation of nanoassemblies (NAs) comprising C225 conjugates Au-PFH-NAs (C-Au-PFH-NAs) for low-intensity focused ultrasound diagnosis ablation of thyroid cancer. C-Au-PFH-NAs showed excellent stability in water, phosphate-buffered saline (PBS), and 20% rat serum. Transmission electron microscopy (TEM) images also revealed the effective construction of C-Au-PFH-NAs as common spherical assemblies. The incubation of C625 thyroid carcinoma with C-Au-PFH-NAs triggers apoptosis, as confirmed by flow cytometry analysis. The C-Au-PFH-NAs exhibited antitumour efficacy in human thyroid carcinoma xenografts, where histopathological results further confirmed these outcomes. Furthermore, we were able to use low-intensity focused ultrasound diagnosis imaging (LIFUS) to examine the efficiency of C-Au-PFH-NAs in thyroid carcinoma in vivo. These findings clearly show that the use of LIFUS agents with high-performance imaging in different therapeutic settings will have extensive potential for future biomedical applications.

Complications Following Radiofrequency Ablation of Benign Thyroid Nodules: A Systematic Review.

Project description:ObjectiveThis systematic review examined whether radiofrequency ablation (RFA) is a safe treatment modality for benign thyroid nodules (BTNs).Data sourcesPubMed, Embase, and the Cochrane Library database were searched for articles that (a) targeted human beings and (b) had a study population with BTNs that were confirmed by fine-needle aspiration cytology and/or core needle biopsy.Study selectionThirty-two studies relating to 3409 patients were included in this systematic review.ResultsBased on literatures, no deaths were associated with the procedure, serious complications were rare, and RFA appears to be a safe and well-tolerated treatment modality. However, a broad spectrum of complications offers insights into some undesirable complications, such as track needle seeding and Horner syndrome.ConclusionsRFA appears to be a safe and well-tolerated treatment modality for BTNs. More research is needed to characterize the complications of RFA for thyroid nodules.
