Purpose: To determine efficacy and safety of thermal ablation (TA) for the local treatment of lung metastases of thyroid cancer., Methods: We retrospectively studied 47 patients from 10 centers treated by TA (radiofrequency, microwaves, and cryoablation) over 10 years. The endpoints were overall survival (OS), local efficacy, complications (CTCAE classification), and factors associated with survival. OS curves after first TA were built using the Kaplan-Meier method and compared with the log-rank test., Results: A total of 107 lung metastases during 75 sessions were treated by radiofrequency (n = 56), microwaves (n = 9), and cryoablation (n = 10). Median follow-up time after TA was 5.2 years (0.2-13.3). OS was 93% at 2 years (95% confidence interval (CI): 86-94) and 79% at 3 years (95% CI: 66-91). On univariate and multivariate analysis with a Cox model, histology was the only significant factor for OS. OS at 3 years was 94% for follicular, oncocytic, or papillary follicular variant carcinomas, compared to 59% for papillary, medullary, insular or anaplastic carcinomas (P = 0.0001). The local control rate was 98.1% at 1 year and 94.8% at 2, 3, 4, and 5 years. Morbidity was low with no major complications (grade 4 and 5 CTCAE) and no complications in 29 of 75 sessions (38.7%)., Conclusions: TA is a useful, safe and effective option for local treatment of lung metastases from thyroid carcinoma. Prolonged OS was obtained, especially for lung metastases from follicular, oncocytic, or papillary follicular variant carcinomas. Achieving disease control with TA delays the need for systemic treatment.

Purpose: Surgical treatment of recalcitrant lateral epicondylitis [LE] remains difficult, with suboptimal results. This prospective study aimed to determine whether percutaneous epicondylar tenotomy combined with PRP injection under ultrasonography control would optimize the surgery results, with an early gain on pain and strength and a rapid return to professional activities at 3 months. The secondary objective was to determine whether clinical or biological risk factors (e.g., composition of the PRP) affected the outcomes., Methods: A total number of 261 Patients with recalcitrant LE underwent percutaneous epicondylar tenotomy under ultrasonography control, coupled with PRP injection. All patients were clinically assessed using VAS pain scale, the functional scores: QuickDASH [Disabilities of the Arm, Shoulder and Hand], Patient-Rated Tennis Elbow Evaluation [PRTEE] and MEPS [Mayo Elbow Performance Score]; Elbow Self-Assessment Score [ESAS]; grip strength; and return to work., Results: At 3-month follow-up, the VAS score decreased by 3.4 points (SD 2.2; p<0.0001), the QuickDASH decreased by 32.9 points (SD 18.9, range 56.1-23.1; p<0.0001), the PRTEE decreased by 14.8 points (SD 19.1, 49.8-26.4; p=0.017), and the MEPS increased by 19.4 points (SD 13.1, 67.4-86.9; p<0.0001); grip strength increased to 8.3kg (SD 10.7; p<0.0001) and increased by 26% (SD 0.60, 0.7-0.96; p<0.0001) as compared with the opposite side. The ESAS showed 78.3% improvement., Conclusion: Treatment of recalcitrant LE by percutaneous tenotomy combined with PRP injection under ultrasonography control provides rapid recovery in terms of pain and strength, with a high level of satisfaction and a high rate of early return to work., Study Design: Case series., (Copyright © 2020 Elsevier Masson SAS.

An 82-year-old man, who was diagnosed in 2002 with an oncocytic (Hürthle cell) thyroid carcinoma, was initially treated by local surgery and was refractory to radioiodine treatment. The patient had successive secondary recurrences from 2006 onwards. Metastases were suspected due to an elevation of thyroglobulin in serum. Hypermetabolic nodules were targeted using FDG PET as well as CT-guided radiofrequency ablations. Thyroglobulin levels decreased following each procedure. 10 years later, tolerance and efficacy are excellent; 23 lung metastases have been treated during 11 sessions without current relapse. Respiratory function and quality of life are not altered. This report illustrates how radiofrequency ablation can be efficiently integrated into the long-term management of poorly aggressive oligometastatic cancer, in combination with other local and/or systemic therapies.

Background: The aim of this study was to evaluate the effectiveness of sunitinib in patients with progressive radioiodine refractory (RAIR) thyroid cancer (TC)., Materials and Methods: A multicentric retrospective analysis was performed of patients treated in six TUmeurs THYroïdiennes REFractaires participating centers. All patients with progressive RAIR TC who were treated with sunitinib outside a clinical trial between August 2007 and March 2015 were retrospectively and consecutively included. The primary endpoint was the overall response rate (ORR) and disease control rate ≥6 months based on RECIST criteria. Secondary endpoints included evaluation of overall survival (OS) and progression-free survival (PFS) from the first dose of sunitinib. Primary and secondary endpoints were also evaluated according to treatment setting: first or second line of tyrosine kinase inhibitor (TKI)., Results: Fifty-seven patients (29 men; 50.8%), mean age 62.2 years (range 43-80 years) with progressive RAIR TC were included. Sunitinib was the first-line TKI treatment for 32 (56.1%) patients and the second-line TKI treatment for 25 (43.9%) patients. For all patients, according to RECIST criteria, ORR was 35.1% (20 patients) and disease control rate ≥6 months was 68.4% (39 patients). No complete response was observed. Six (10.5%) patients showed disease progression. When sunitinib was used as first-line TKI therapy, ORR was 46.9% (15/32 patients), and disease control rate ≥6 months was 75% (24/32 patients). When sunitinib was used as second-line TKI therapy, ORR was 20% (5/25 patients), and disease control rate ≥6 months was 60% (15/25 patients). The median OS and PFS were 21.0 (range 15-29) and 10.2 months (range 6-13), respectively, for all patients. With sunitinib as first-line TKI-therapy, median OS and PFS was 30.0 (range 19.0-53.0) and 15 (range 7.0-21.0) months, respectively. As second-line therapy, median OS and PFS were 13 (range 8.0-20.0) and 6 (range 5.0-11.0) months, respectively. Eleven (19.3%) patients experienced grade 3 toxicity, and four patients (7.0%) experienced grade 4 toxicity., Conclusion: The efficacy of sunitinib as first- and second-line TKI therapy in a large cohort of patients treated for progressive RAIR TC is herein reported. Further prospective studies are needed to evaluate the effectiveness of sunitinib in RAIR TC.

Effective adverse event (AE) management is critical to maintaining patients on anticancer therapies. The DECISION trial was a multicenter, randomized, double-blind, placebo-controlled, Phase 3 trial which investigated sorafenib for treatment of progressive, advanced, or metastatic radioactive iodine-refractory, differentiated thyroid carcinoma. Four hundred and seventeen adult patients were randomized (1:1) to receive oral sorafenib (400 mg, twice daily) or placebo, until progression, unacceptable toxicity, noncompliance, or withdrawal. Progression-free survival, the primary endpoint of DECISION, was reported previously. To elucidate the patterns and management of AEs in sorafenib-treated patients in the DECISION trial, this report describes detailed, by-treatment-cycle analyses of the incidence, prevalence, and severity of hand-foot skin reaction (HFSR), rash/desquamation, hypertension, diarrhea, fatigue, weight loss, increased serum thyroid stimulating hormone, and hypocalcemia, as well as the interventions used to manage these AEs. By-cycle incidence of the above-selected AEs with sorafenib was generally highest in cycle 1 or 2 then decreased. AE prevalence generally increased over cycles 2-6 then stabilized or declined. Among these AEs, only weight loss tended to increase in severity (from grade 1 to 2) over time; severity of HFSR and rash/desquamation declined over time. AEs were mostly grade 1 or 2, and were generally managed with dose interruptions/reductions, and concomitant medications (e.g. antidiarrheals, antihypertensives, dermatologic preparations). Most dose interruptions/reductions occurred in early cycles. In conclusion, AEs with sorafenib in DECISION were typically grade 1 or 2, occurred early during the treatment course, and were manageable over time., (© 2015 The authors.)

Thermal ablation (radiofrequency, microwave, cryosurgery, laser interstitial thermal therapy) is being used more frequently as a local treatment of secondary but also primary cancers and benign lesions. It has a low morbidity and is repeatable. The problem is that computed tomographic scan has limits, and RECIST criteria are not applicable. The objective of this article is to summarize the usefulness and pitfalls of PET/computed tomography in detecting a relapse after thermal ablation as soon as possible., (Copyright © 2015 Elsevier Inc.

Purpose: In the ESTIMABL phase III trial, the thyroid ablation rate was equivalent for the two thyroid-stimulating hormone (TSH) stimulation methods (thyroid hormone withdrawal [THW] and recombinant human TSH [rhTSH]) and the two iodine-131 ((131)I) activities (1.1 or 3.7 GBq). The objectives of this article were to present health-related quality-of-life (HRQoL) results and a cost-effectiveness evaluation performed alongside this trial., Patients and Methods: HRQoL and utility were longitudinally assessed, from random assignment to the follow-up visit at 8 ± 2 months for the 752 patients with thyroid cancer, using the Short Form-36 and the EuroQoL-5D questionnaires, respectively. A cost-effectiveness analysis was performed from the societal perspective in the French context. Resource use (hospitalization for (131)I administration, rhTSH, sick leaves, and transportation) was collected prospectively. We used the net monetary benefit approach and computed cost-effectiveness acceptability curves for both TSH stimulation methods and (131)I activities. Sensitivity analyses of the costs of rhTSH were performed., Results: At (131)I administration, THW caused a clinically significant deterioration of HRQoL, whereas HRQoL remained stable with rhTSH. This deterioration was transient with no difference 3 months later. rhTSH was more effective than THW in terms of quality-adjusted life-years (QALYs; +0.013 QALY/patient) but more expensive (+€474/patient). The probability that rhTSH would be cost effective at a €50,000/QALY threshold was 47% in France. The use of 1.1 GBq of (131)I instead of 3.7 GBq reduced per-patient costs by €955 (US$1,018) but with slightly decreased efficacy (-0.007 QALY/patient)., Conclusion: rhTSH avoids the transient THW-induced deterioration of HRQoL but is unlikely to be cost effective at its current price., (© 2015 by American Society of Clinical Oncology.)

Background: A randomized phase III trial demonstrated that vandetanib treatment is effective in patients with metastatic medullary thyroid cancer (MTC), leading to regulatory approval, but its use may be associated with toxicities that require specific monitoring and management. The objective of the present study performed in France was to describe the toxicity profile and efficacy of vandetanib treatment when given outside any trial., Methods: Sixty-eight patients were treated with vandetanib in the frame of a temporary use authorization (ATU) in France from August 2010 to February 2012, when the drug was available on request for patients with locally advanced or metastatic MTC. Patients were registered by the French health authorities, and characteristics, treatment parameters, toxicity profile, and efficacy were retrospectively reviewed. Eight patients were excluded from the analysis because vandetanib treatment was not administered (n=3), had been given in a trial before ATU (n=3), or was given for a non-MTC cancer (n=2)., Results: Data from the 60 MTC patients were analyzed. Mean age was 58 years (range 11-83 years), 39 patients were male, and six had hereditary MTC. Fifty-six (93%) had metastatic disease in the mediastinum (82%), bones (65%), liver (53%), or lung (53%), and four had only locally advanced disease. At the time of study evaluation, with a median follow-up of 20 months and a median duration of treatment of 9.7 months (range 0.3-36 months), 15 patients were continuing vandetanib treatment (range 18-36 months). Median progression-free survival was 16.1 months. Twenty-five patients discontinued treatment for disease progression (range 0.3-29 months). Best tumor response was a complete response in one patient, a partial response in 12 (20%), stable disease in 33 (55%), and progression in seven patients (12%). All patients had at least one adverse event (AE) during treatment. The main AEs were skin toxicity, diarrhea, and asthenia. Sixteen patients (27%) discontinued treatment for toxicity, and one patient died from vandetanib-induced cardiac toxicity., Conclusions: Vandetanib is an effective option for patients with advanced MTC. AEs should be monitored carefully and should be minimized by educating both patients and care providers and by applying symptomatic treatment and dose reduction.
