[Retrospective analysis of papillary thyroid microcarcinoma cases treated between 2001 and 2010 in the Hungarian National Institute of Oncology].

The standard treatment of papillary microcarcinomas (mPTC; ≤1 cm) regardless of their size, was similar to the advanced ones till the recent past: immediate surgery ± radioactive iodine (RAI) therapy. However, the American Thyroid Association (ATA) 2015 guidelines accept the active surveillance in selected cases. We performed a retrospective analysis on the clinical data of 103 patients with PTmC in a single (62.

[On-site fine-needle aspiration cytology of thyroid nodules. Quality assurance of the Bethesda System for Reporting Thyroid Cytopathology (2008)].

Introduction: The methods available for the diagnosis of thyroid nodules include physical examination, imaging, laboratory and fine-needle aspiration cytology tests.

Aim: The aim of this study was to determine the quality assurance of fine-needle aspiration cytology of thyroid nodules.

Method: Cytology results were rated to 6 categories according to the Bethesda System for Reporting Thyroid Cytopathology (2008) (I.

Introduction: The presence of a substernal goiter which compresses the adjacent structures is per se an indication for resection, mostly total thyreoidectomy should be performed either by a head and neck or general surgeon. In about 1-10% of the cases the goiter is located behind the sternum, and the removal requires different surgical technique.

Materials And Methods: Authors operated 182 patients between 2000-2014 with substernal goiter which all reached the level of the jugulum.

Dynamic Contrast-Enhanced MRI Parameters as Biomarkers in Assessing Head and Neck Lesions After Chemoradiotherapy Using a Wide-Bore 3 Tesla Scanner.

Pilot studies have shown promising results in characterizing head and neck tumors (HNT) using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), differentiating between malignant and benign lesions and evaluating changes in response to chemoradiotherapy (CRT). Our aim was to find DCE-MRI parameters, biomarkers in evaluating the post-CRT status. Two hundred and five patients with head and neck lesions were examined with DCE-MRI sequences.

[Pedicled supraclavicular osteocutan island flap for tracheostoma closure].

Authors present a case of a 52-year-old female patient, who underwent an emergency tracheostomy due to life threatening dyspnoea caused by an external compression of a large goiter. Total thyreoidectomy needed to be carried out later, too. Since the atypical tracheostomy did not close spontaneously a reconstruction was planned.

[Our clinical experience with fibula free flap].

Oral cancer incidence in Hungary is strikingly high, even by international standards. In most cases the tumours are to be treated in advanced stage. Hence it follows that we are often forced to remove a part of the mandible, too.

[Applicable methods of reconstruction for the replacement of soft tissue after the radical resection of oral tumors].

In Hungary the number of oral and pharyngeal cancers is alarmingly high. While the mortality rate in 1955 was 282, by 2005 it rose to 1567. However, in the last 1-2 years stagnation can be observed.

[Laser surgery of head and neck lesions at the National Institute of Oncology, Budapest].

In spite of the continued expansion of non-surgical therapeutic modalities surgery still plays an important role in the treatment of head and neck cancer. Parallel with the use of conventional approaches, more sophisticated surgical approaches, like the use of laser in oncologic surgery, appeared with a more favorable outcome. Laser is a precise surgical tool, particularly when coupled to an operating microscope (with a variable spot size micromanipulator), allowing microprecision and hemostatic ability.

[Clinical significance of serum thyroglobulin and antithyroglobulin antibody in differentiated thyroid cancer after thyroid ablation].

Serum thyroglobulin (Tg) is a suitable marker for differentiated thyroid carcinoma following total thyroid ablation. Between 1998 and 2003, serum samples from 715 papillary and 179 follicular tumor patients treated with total/nearly total thyroidectomy and radioiodine ablation therapy were collected. According to the "Guidelines for Oncotherapy in Hungary", serum Tg, antithyroglobulin antibody (TgAb), TSH and FT4 levels were measured in periods of 3 months following the first treatment and of 6 months after 2 years.

PET identifies transitional metabolic change in the spinal cord following a subthreshold dose of irradiation.

Positron emission tomographic (PET) investigations were performed to obtain in vivo information on symptomless radiation-induced pathological changes in the human spinal cord. PET investigations were carried out prior to radiotherapy and during the regular follow-up in an early hypopharyngeal cancer patient (the spinal cord was irradiated with a biologically effective dose of 80 Gy2), with [18F]fluorodeoxyglucose (FDG), [11C]methionine and [15O]butanol as tracers; radiosensitivity and electroneuronographic (ENG) studies were also performed. A very low background FDG accumulation (mean standardized uptake values, i.

[Lingual thyroid: a rare disease resembling base of tongue neoplasm].

The ectopic thyroid gland occurring in the midline of the base of tongue is a rare developmental anomaly. It may cause differential diagnostic problems with real malignant tumor. Symptoms, if where are any: foreign-body-feeling, swallowing difficulties, dyspnea, articulation disorders, bleeding and hypothyroidism, but in many cases the diagnosis is accidental.

Markov model-based estimation of individual survival probability for medullary thyroid cancer patients.

Unlabelled: The relatively benign, but occasionally rapidly fatal clinical course of medullary thyroid cancer (MTC) has raised the need for individual survival probability estimation. A retrospective study on 91 MTC clinical case histories with a mean follow-up of 6 years indicated prevalences of local, regional and distant residual tumor on primary care completion of 23%, 54% and 54%, respectively. Local, regional and distant relapses during follow-up occurred in 8%, 23% and 26% of the patients, with a cause-specific death in 26% of the cases.
