Filter by:Papillary thyroid carcinoma (PTC) is the most common thyroid cancer and has a good prognosis.According to the 2015 American thyroid association (ATA) guidelines, no gross extrathyroidal extension and the number of pathological lymph node micrometastases (<0.2cm) ≤5 were defined as the low recurrence risk group. After total thyroidectomy and radioiodine treatment, the probability of disease-free status (irritant Tg<1ng/ml, no evidence of other disease recurrence) is about 78%-91%, and the probability of structural recurrence is about 1%-10%. In recent years, due to the further understanding of PTC, surgeons tend to become more conservative in treatment, such as active observation or reducing the extent of surgery. The indication for lobectomy has been extended to tumors <4cm without extrathyroidal extension and clinical lymph node metastasis. For patients treated with lobectomy, current guidelines recommend that Thyroid Stimulating Hormone (TSH) be controlled at 0.5-2 mU/L, but evidence on the prognostic benefits of this TSH inhibition range is lacking.In recent years, a number of studies have suggested that if postoperative TSH in low-risk patients after lobectomy is acceptable within the reference range, it means that a considerable number of patients have a high probability of not receiving thyroxine replacement therapy after surgery, which can significantly improve their quality of life.A previous retrospective study from our institute showed no significant association between TSH levels after lobectomy and prognosis.The aim of this study was to evaluate the benefits and risks of postoperative TSH levels within the reference range (0.4-5 mU/L) in patients with low-risk papillary thyroid cancer who underwent lobectomy.In order to improve the effect of longer recurrence and death time of PTC, the investigators also performed postoperative thyroglobulin and its antibody for short-term treatment response evaluation.
papillary thyroid carcinoma (PTC) is the most common thyroid cancer and has a good prognosis. Surgery is the primary treatment for PTC, and occult lymph node metastasis is not uncommon (20%-80%).The lymph node metastasis of PTC is mostly along the lymphatic drainage path station by station, and most of the first metastasis is to the central lymph node. According to the 2015 American Thyroid Association recommendation, prophylactic central lymph node dissection is recommended for patients with primary T3-4 or cN1b without central lymph node involvement. However, PTC with primary site T1-2, no external invasion and cN0 could not be dissected by central lymph node.Previous studies have suggested that prophylactic dissection should be performed to improve disease-specific survival, reduce local recurrence, improve recurrence risk and treatment response assessment, and help RAI decision making. Although routine prophylactic central lymph node dissection may detect occult lymph node metastasis, the need for further dissection of the recurrent laryngeal nerve and the parathyroid gland may lead to an increased incidence of complications, while its effect on reducing the risk of recurrence and improving prognosis is unclear, and the impact on long-term outcomes may be small.Previous retrospective studies in our institution have shown that routine central neck dissection does not significantly reduce the risk of recurrence. This study was designed to evaluate the benefits and risks of prophylactic central lymph node dissection in cT1b-T2N0 patients with papillary thyroid carcinoma. In order to ameliorate the effects of relapse and long time of death of PTC, thyroglobulin and its antibodies were also evaluated for short-term treatment response after surgery.
Aldosterone excess can cause oxidative stress leading to DNA damage in vitro and in vivo. Single case reports demonstrated a coincidence of primary aldosteronism (PA) with different malignancies. A higher prevalence of thyroid nodules and non-toxic multinodular goiter was described in patients with PA compared to those with essential hypertension (EH). A single study showed an association between PA and papillary thyroid cancer (PTC), but without a paired control group. Objective: To assess PA prevalence in a transversal cohort of patients with PTC and EH compared to a paired control group with HT.
Tumor deposits (TD), nodules in the peritumoral adipose tissue with no architectural residue of lymph node, which is a definition often being confusing to the extranodal extension (ENE), have been described in several malignancies and linked to a worse prognosis. In gastric cancer and colon cancer, TD and ENE should be distinguished and collected separately in 8th AJCC manual. However, in thyroid cancer, TD as a collection variable was absence in both the 8th AJCC manual and the 2015 ATA guideline. This is a study that revealed the presence of TD by reviewing a large number of papillary thyroid carcinoma (PTC) specimens and explored its prognostic value by constructing a nomogram to accurately predict disease-free survival in PTC patients.
Blood will be drawn 1 month before and 2 month after regular radioactive iodine treatment. Monocytes will be isolated. The three main outcomes are whole blood counts, cytokine production upon in vitro stimulation of monocytes and in vitro ROS production by monocytes. These results are compared between patients treated in adjuvant setting and patients treated for persistent structural disease, and between pre- and post-treatment status.
A prospective cohort of papillary thyroid carcinoma(PTC), patients who received thermal ablation in our hospital since February 2023 was established as the study object. Preoperative and postoperative demographic data, ultrasonography, other relevant laboratory tests, and thyroid disease-related scales such as fatigue, depression, and stress were collected. The influencing factors of PTC recurrence were analyzed.
An observational cross-sectional case-control study on the postoperative quality of life (5 aspects, general quality of life, thyroid specific quality of life, scar appearance, voice and swallowing functions) of papillary thyroid carcinoma (PTC) patients underwent thyroid lobectomy via different approach, open vs trans-axillary. The patients are recruited in Peking Union Medical College Hospital (PUMCH) from 2020 to 2023 and are evaluated by follow-up with both outpatient visits and questionnaires made up of 9 validated scales.
Papillary cancer is a disease that spreads through lymphatic ways and its treatment is surgery. We performed prophylactic central dissection in addition to bilateral total thyroidectomy in patients with bethesda 5 and bethesda 6 biopsy results. We evaluated the pathology results retrospectively.
Optimal surgical technique for neck dissection (LND) in thyroid carcinoma remains a subject of debate. Fascial ND (FND) implies the removal of the superficial and middle layers of the deep cervical fascia en bloc with lymph-nodes containing fibro-fatty tissue (levels IIa-Vb and VI-VII for cN1b patients). This retrospective cohort study was designed to compare FND with standard, non-fascial, selective ND (SND).
The main aim of the study is to evaluate peri-operative surgical characteristics, operation extent, postoperative morbidity, and outcomes in patients undergoing surgery for advanced thyroid cancer in different European centers using the EUROCRINE® database.
