Purpose The aim of the study was to evaluate the functionality of vocal folds (VF) by real-time, high-resolution ultrasonography (US) and to correlate the imaged features to results of laryngological examination (LE). Methods The study group comprised 50 patients (41 females and nine males), qualified to thyroidectomy. All the patients had LE and US examination before and 2 days, 2 months, and 3 months after the surgery. We used high-resolution US imaging to identify VFs and, subsequently, a pulsed Doppler and Doppler gate to quantify the tissue displacement velocity in the vibrating VF section. Results LE revealed unilateral VF paralysis in two patients. VF dysfunction was diagnosed in other four subjects. In simultaneously performed US examination, changes in VF displacement velocity (VFDV) were observed in ten patients. In two subjects, VFDV was below 30 cm/s— patients with VF paralysis, diagnosed in LE. In a further eight cases, we observed VFDV decrease by 50%, comparing to preoperative values. Both US-imaging and LE, performed after the 3-month follow-up, confirmed the transitional character of the above-mentioned pathologies. Conclusions US imaging of the VFs correlated with LE results, while being a minimally invasive, easily reproducible, and inexpensive method of examining VF functionality. Thanks to many recording options, it may soon become a perfect tool for an early identification of postoperative VF dysfunction with its later monitoring. To our knowledge, it is the first application of US and Doppler gate modes for VFDF quantification; however, an analysis on a larger group of patients is necessary to standardize the technique.

PURPOSE: Selumetinib can increase radioactive iodine (RAI) avidity in RAI-refractory tumors. We investigated whether selumetinib plus adjuvant RAI improves complete remission (CR) rates in patients with differentiated thyroid cancer (DTC) at high risk of primary treatment failure versus RAI alone. METHODS: ASTRA (ClinicalTrials.gov identifier: NCT01843062 ) is an international, phase III, randomized, placebo-controlled, double-blind trial. Patients with DTC at high risk of primary treatment failure (primary tumor > 4 cm; gross extrathyroidal extension outside the thyroid gland [T4 disease]; or N1a/N1b disease with ≥ 1 metastatic lymph node(s) ≥ 1 cm or ≥ 5 lymph nodes [any size]) were randomly assigned 2:1 to selumetinib 75 mg orally twice daily or placebo for approximately 5 weeks (no stratification). On treatment days 29-31, recombinant human thyroid-stimulating hormone (0.9 mg)–stimulated RAI (¹³¹I; 100 mCi/3.7 GBq) was administered, followed by 5 days of selumetinib/placebo. The primary end point (CR rate 18 months after RAI) was assessed in the intention-to-treat population. RESULTS: Four hundred patients were enrolled (August 27, 2013-March 23, 2016) and 233 randomly assigned (selumetinib, n = 155 [67%]; placebo, n = 78 [33%]). No statistically significant difference in CR rate 18 months after RAI was observed (selumetinib n = 62 [40%]; placebo n = 30 [38%]; odds ratio 1.07 [95% CI, 0.61 to 1.87]; P = .8205). Treatment-related grade ≥ 3 adverse events were reported in 25/154 patients (16%) with selumetinib and none with placebo. The most common adverse event with selumetinib was dermatitis acneiform (n = 11 [7%]). No treatment-related deaths were reported. CONCLUSION: Postoperative pathologic risk stratification identified patients with DTC at high risk of primary treatment failure, although the addition of selumetinib to adjuvant RAI failed to improve the CR rate for these patients. Future strategies should focus on tumor genotype–tailored drug selection and maintaining drug dosing to optimize RAI efficacy.

Significant advances have been made in thyroid can­cer research in recent years, therefore relevant clinical guidelines need to be updated. The current Polish guidelines “Diagnostics and Treatment of Thyroid Carcinoma” have been formulated at the “Thyroid Cancer and Other Malignancies of Endocrine Glands” conference held in Wisła in November 2015 [1].

Although many tumours of head and neck have been successfully embolized, the number of publications on the application of selective embolization of thyroid arteries (SETA) is limited. The aim of the present study is to evaluate the safety, efficacy and possible indications and contraindications for preresective or palliative SETA in thyroid cancer. The study group comprised 20 patients with thyroid tumours: 7 cases of advanced inoperable anaplastic thyroid cancer (ATC) and 13 cases of differentiated thyroid carcinoma (DTC). All the patients underwent SETA of the superior and/or inferior thyroid arteries. After SETA, selective angiographies of thyroid arteries were performed to ensure that the targeted arteries had been completely occluded. In all the cases, SETA decreased the blood flow through the thyroid. Preresective SETA limited bleeding during surgery and decreased operating time. We observed a massive increase of thyroglobulin (Tg) concentrations in cases of DTC that started 36–48 h after SETA and did not occur in cases of ATC. Although SETA had no influence on the mortality of ATC patients, they reported improvements in swallowing, breathing and decrease of the pain. Concluding, SETA is minimally invasive and safe method limiting blood flow through thyroid tumours. In DTC patients, SETA causes ischaemic necrosis of the gland which results in important increases in serum concentrations of Tg. Therefore, thyroidectomy should be performed during the first 36 h after preresective embolization. Moreover, SETA may become an attractive option of palliative treatment for ATC patients with intractable bleeding, pain or signs of tracheal and oesophageal compression.

Revised Guidelines of Polish National Societies Prepared on the initiative of the Polish Group for Endocrine Tumours approved in their final version between November 16th and 28th, 2015 by the Scientific Committee of the V Conference "Thyroid Cancer and other malignancies of endocrine glands" organised between November 14th and 17th, 2015 in Wisla, Poland; called by the following Societies: Polish Endocrine Society, Polish Society of Oncology, Polish Thyroid Association, Polish Society of Pathologists, Society of Polish Surgeons, Polish Society of Surgical Oncology, Polish Society of Clinical Oncology, Polish Society of Radiation Oncology, Polish Society of Nuclear Medicine, Polish Society of Paediatric Endocrinology, Polish Society of Paediatric Surgeons, Polish Society of Ultrasonography Gliwice-Wisła, 2015 DECLARATION: These recommendations are created by the group of delegates of the National Societies, which declare their willingness to participate in the preparation of the revised version of the Polish Guidelines. The members of the Working Group have been chosen from the specialists involved in medical care of patients with thyroid carcinoma. Directly before the preparation of the Polish national recommendations the American Thyroid Association (ATA) published its own guidelines together with a wide comment fulfilling evidence-based medicine (EBM) criteria. ATA Guidelines are consistent with National Comprehensive Cancer Network (NCCN) Recommendation. According to the members of the Working Group, it is necessary to adapt them to both the specific Polish epidemiological situation as well as to the rules referring to the Polish health system. Therefore, the Polish recommendations constitute a consensus of the experts' group, based on ATA information. The experts analysed previous Polish Guidelines, published in 2010, and other available data, and after discussion summed up the results in the form of these guidelines. It should be added that Part II, which constitutes a pathological part, has been available at the website of the Polish Society of Pathologists for acceptance of the members of the Society, and no essential comments have been proposed. The Members of the Group decided that a subgroup elected from among them would update the Guidelines, according to EBM rules, every year. The Revised Guidelines should help physicians to make reasonable choices in their daily practice; however, the final decision concerning an individual patient should be made by the caring physician responsible for treatment, or optimally by a therapeutic tumour board together with the patient, and should take into consideration the patient's health condition. It should be emphasised that the recommendations may not constitute a strict standard of clinical management imposed on medical staff. The data from clinical trials concerning numerous clinical situations are scarce. In such moments the opinion of the management may differ from the recommendations after considering possible benefits and disadvantages for the patient.
