Background: Papillary thyroid microcarcinoma (PTMC), a subtype of papillary thyroid carcinoma ≤ 1 cm in diameter, has shown a marked increase in incidence in recent decades, largely due to the widespread use of neck ultrasonography and fine needle aspiration cytology. Despite its generally indolent course, optimal management of PTMC remains controversial, with treatment strategies ranging from active surveillance to total thyroidectomy. Methods: This retrospective study analyzes five years of experience at a single tertiary care center, including 130 patients diagnosed with PTMC following thyroid surgery between July 2018 and December 2023. Clinical, cytological, and pathological data were collected and analyzed to identify factors influencing surgical decision-making and postoperative outcomes. Patients underwent either total thyroidectomy or hemithyroidectomy, with central and lateral lymph node dissection performed as indicated. Follow-up included clinical and biochemical surveillance for a mean duration of 3 years. Results: Total thyroidectomy was performed in 89.3% of patients, while hemithyroidectomy was limited to 10.7%. Multifocality was observed in 26.1% of cases, with bilateral involvement in 17.7%. Occult lymph node metastases were found in 14.6% (central compartment) and 3.8% (lateral neck). Postoperative radioactive iodine therapy was administered in 23.8% of patients. At final follow-up, 90.7% were disease-free. No significant predictors of recurrence or adverse outcomes were identified, though multifocality and lymph node involvement influenced surgical planning. Conclusions: Our findings support a risk-adapted surgical approach to PTMC, favoring total thyroidectomy in patients with suspicious or multifocal disease to avoid reoperation. While active surveillance and minimally invasive techniques are emerging, total thyroidectomy remains a safe and effective strategy in selected cases. Prospective, multicenter studies are needed to further refine management guidelines for this increasingly common thyroid malignancy. Full article

Background and Objectives: After introducing the single-port robotic surgical system (da-Vinci SP), thyroid surgeries using da-Vinci SP are becoming more popular. Although many methods have been designed for thyroidectomy using the da-Vinci SP, there are very few reports on methods that can perform not only thyroidectomy but also lateral cervical lymph node dissection. In this study, we want to report the first clinical experience with SPRA-MRND (Single Port Robotic Areolar-Modified Radical Neck dissection), using right breast access. Materials and Methods: From April 2024 to January 2025, a total of 24 robotic MRNDs were performed, of which 11 were SPRA-MRNDs. The remaining 13 were performed using conventional BABA surgery. The two data sets were compared through retrospective medical record analysis. Results: There were no significant differences regarding patient characteristics, pathologic variables and oncologic outcomes between the two groups. However, SPRA group showed significantly shorter operation time (182.1 ± 27.5 vs. 213.1 ± 31.5 min, p = 0.017), higher immediate postoperative calcium level (calcium: 8.7 ± 0.5 vs. 8.0 ± 0.8 mg/dL, p = 0.014) and lower drainage amount (98.1 ± 33.2 vs. 146.4 ± 43.2 mL, p = 0.005). Conclusions: Our initial experience has shown that SPRA-MRND is performed safely. We propose SPRA-MRND as a good method for minimally invasive robotic surgery. Full article

Background: Ectopic organ-associated conditions belong to the larger panel of developmental ailments, and among this challenging medical and surgical chapter, ectopic endocrine glands-related picture is mostly focused on the presence of the ectopic parathyroid and thyroid. Ectopic thyroid tissue within mediastinum (ETTM) stands for a less common ETT site; while, globally, less than 1% of the mediastinum masses are ETTM. Objective: We aim to introduce a rare case of ETTM in a senior lady to whom one-time synchronous thyroidectomy with ETT removal was successfully performed via a minimally invasive modern procedure upon cervicotomy and intra-operatory use of the Cooper thymectomy retractor. Results: The panel of pros and cons with respect to providing endocrine thoracic surgery for ETTM resection in a 73-year-old subject is discussed amid a PubMed search of original English-language original reports from January 2000 until 15 August 2024 in order to identify similar distinct cases (individuals of 70 years or older who underwent surgery for ETTM). Conclusions: 1. We propose the term “three-leaf-clover thyroid” to capture the imaging essence of having an enlargement of both (eutopic) thyroid lobes and ETTM. 2. The modern surgical approach under these circumstances provided a rapid patient recovery with a low rate of complications and a minimum hospital stay. Hence, the procedure may be expanded to older patients after a careful consideration of their co-morbidities and of the need to releasing connected complaints (e.g., a 7-month history of intermittent dyspneea was found in this case with post-operatory remission). 3. The management remains a matter of individualised decision, and age may not be a limiting factor. 4. At the present time, this case adds to the very limited number of similar published cases in the mentioned age group that we could identify (seven patients, aged between 72 and 84; male-to-female ratio of 5 to 2; the rate of malignant ETTM was 3/7); of these cases, not all were reported to have a trans-cervical approach, and none reported the use of the Cooper thymectomy retractor to help the overall surgical procedure. This innovative surgical procedure offers the advantage of avoiding a sternotomy incision which has clear functional and aesthetic implications, while the video-assisted approach allows optimal visualization of the mediastinal anatomy and safe vascular sealing under visual control, without the risk of a major hemorrhage.

Background: The incidence of various types of cancer, for example, papillary thyroid carcinoma (PTC), is on the rise. Since therapeutic success depends greatly on early diagnosis, reliable diagnostic biomarkers must be identified, and easy-to-apply tools for detecting them must urgently be standardized. Here, we contribute to solving this medical challenge by assessing miRNAs suspected of promoting carcinogenesis in extracellular vesicles (EVs) that can be routinely obtained via liquid biopsy. We profit from current progress in cancerology that provides innovations in liquid biopsy and EVs analysis, along with the identification of miRNAs and chaperone system (CS) components implicated in carcinogenesis. Methods: We measured in EVs obtained from circulating blood plasma from PTC patients the levels of three miRNAs implicated in thyroid cancer, hsa-miR-1-3p, hsa-miR-206, and hsa-miR-221-3p, and most likely involved in the regulation of two members of the CS, Hsp60 and CCT. EVs were isolated from the plasma of patients with PTC and controls with benign goiter (BG) and from the culture medium of a PTC cell line (MDAT32) and were appropriately characterized. Results: The levels of miRNAs determined by RT-qPCR were consistently higher in PTC patients and decreased down to control levels after thyroidectomy. Bioinformatics showed that the miRNAs target genes are associated with the molecular pathogenesis of PTC. Conclusions: Our exploratory study reaffirms the potential in clinics of the selected miRNAs in EVs as useful biomarkers of PTC easily accessible via liquid biopsy, which is minimally invasive and amenable to periodic repetition, an improvement compared to the established fine-needle aspirate biopsy.

Thyroid cancer is among the most common endocrine malignancies, necessitating effective surgical interventions. Traditional open cervicotomy has long been the standard approach for thyroidectomy. However, the advent of robotic surgery has introduced new possibilities for minimally invasive procedures with benefits in terms of cosmetic outcomes, enhanced precision, comparable complication rates, and reduced recovery time. This study mainly reviewed the most widely used and well-known robotic thyroidectomy approaches: the transaxillary approach, the bilateral axillo–breast approach, and the transoral approach. This review examines the current status and future potential of robotic surgery in thyroid cancer treatment, comparing its efficacy, safety, and outcomes with those of conventional open cervicotomy. Challenges such as a longer operative time and higher costs exist. Future directions include technological advancements, tele-surgery, single-port surgery, and the integration of artificial intelligence. Robotic surgery holds promise in optimizing patient outcomes in thyroid cancer treatment. Full article

Thyroidectomy is a commonly performed surgery for thyroid cancer, Graves’ disease, and thyroid nodules. With the increasing incidence of thyroid cancer, understanding the anatomy and surgical techniques is crucial to ensure successful outcomes and minimize complications. This review discusses the anatomical considerations of the thyroid and neck, including lymphatic drainage and the structures at risk during thyroidectomy. Emphasis is placed on the significance of cautious dissection to preserve critical structures, such as the parathyroid glands and recurrent laryngeal nerve. Neck dissection is also explored, particularly in cases of lymph node metastasis, in which its proper execution is essential for better survival rates. Additionally, this review evaluates various thyroidectomy techniques, including minimally invasive approaches, highlighting their potential benefits and limitations. Continuous surgical knowledge and expertise updates are necessary to ensure the best results for patients undergoing thyroidectomy. Full article

Minimal extrathyroid extension (mETE) effect on papillary thyroid carcinoma (PC) prognosis is still debated even more so now that this factor has been removed in the 8th AJCC Edition, supporting the hypothesis that mETE is not associated with aggressive tumors. We retrospectively enrolled 91 PC patients (Group 1) submitted to total thyroidectomy and radioiodine ablation. At the time of the primary tumor surgery, mETE was ascertained in all patients with no other risk factors, such as multifocality, vascular invasion, neck and distant metastases, and aggressive histological variants. As controls, 205 consecutive matched PC patients (Group 2) without mETE and the aforementioned risk factors were enrolled. During the follow-up (average 8 years), 16/91 (17.58%) Group 1 patients and 15/205 (7.32%) Group 2 patients developed metastases (p = 0.0078). Cox regression analysis showed an increased risk of metastases in patients with mETE (HR: 2.58 (95% CI 1.28–5.22) p = 0.008). Disease-free survival (DFS) was significantly lower in patients with mETE than in controls (p = 0.0059). The present study seems to demonstrate that mETE can be associated with an aggressive PC and can be considered, even alone without other risk factors, an independent factor of unfavorable DFS. Thus, by excluding mETE in the 8th AJCC Edition, patient care and management could be compromised. Full article

The biology of papillary thyroid carcinoma (PTC) in young patients is poorly understood, and there are conflicting data regarding the recurrence for younger patients compared to older patients. We retrospectively analyzed 2348 clinically node-negative (cN0) PTC patients who underwent a thyroid lobectomy between 2008 and 2017. Young age was defined as less than 35 years old. The clinicopathological characteristics and oncologic outcomes of the young age group were compared to those of the older age group. The number of young age cN0 PTC patients accounted for 20.7% of the enrolled patients, and 24.2% were upstaged into pathologic N1a. The young age group had a significantly larger proportion of females, endoscopic/robotic thyroid lobectomies, stage N1a, and larger tumor sizes. Post-lobectomy recurrences were significantly higher in the young age group. In the Cox analysis, young age, large tumor size, and stage N1a were significant risk factors. The multivariate analysis reveals that young age and stage N1a are significant risk factors. Conversely, minimally invasive or robot-endoscopic thyroidectomies were not risk factors for post-lobectomy recurrence compared to conventional thyroidectomies. While young patients with a stage N1a had a significant risk factor for post-lobectomy recurrence, endoscopic/robotic thyroidectomy was as feasible and safe as conventional thyroidectomies in the median seven-year oncologic follow-up. Further high-quality studies are needed to elucidate the relationship between age and the risk of post-lobectomy recurrence. Full article

Background and Objectives: Recently, the single-port (SP) robotic system was introduced for minimally invasive operative techniques. Thus, this study aimed to validate the safety and feasibility of SP trans-axillary robotic thyroidectomy (SP-TART) through experiences in a single tertiary institution. Materials and Methods: This study retrospectively analyzed 100 consecutive patients who underwent SP-TART from October 2021 to June 2022 in Seoul St. Mary’s Hospital in Seoul, Korea. We analyzed the clinicopathological characteristics and perioperative outcomes, including complications. Results: Less than total thyroidectomy (LTT) was performed in 81, total thyroidectomy (TT) in 16, and TT with modified radical neck dissection (mRND) in 3 patients. The mean operation time (min) was 53.3 ± 13.7, 86.3 ± 15.1, and 245.7 ± 36.7 in LTT, TT, and TT with mRND, respectively. The mean postoperative hospital stay was 2.0 ± 0.2, 2.1 ± 0.3, and 3.7 ± 1.5 days, respectively. A total of 84 cases of thyroid cancer were included, and 97.6% of them (82 cases) were papillary carcinoma and the rest were follicular and poorly differentiated carcinomas. Regarding complications, five cases had major complications, including three cases of vocal cord palsy and two cases of transient hypoparathyroidism. Conclusions: SP-TART is safe and feasible with a short operation time and a short length of hospital stay. Full article

The aim of this study was to evaluate the diagnostic accuracy of a neuromonitoring protocol—the Abu Dhabi Neural Mapping protocol (ADNM)—using a new device, Nim-Vital™, during minimally invasive thyroidectomy in the early identification of non-recurrent laryngeal nerve (n-RLN) problems and the preservation of its function. Method: Patients with thyroid disorders that required thyroid resection, who were admitted to the Department of Surgery at Burjeel Hospital, Abu Dhabi, between January and July 2022, were included in the study. The data were extracted from a prospective database and were analyzed retrospectively. All nerves at risk were identified and exposed at seven precisely defined anatomical points, with strict adherence to the intraoperative technical steps of neuromonitoring. These were sequentially applied to the vagal nerve (VN), the superior laryngeal nerve (SLN), and the recurrent laryngeal nerve (RLN). In the next step after the creation of the skin-platysma flap, the strap muscle’s lateral border was moved from the medial limb of the sternocleidomastoid without using any electrical device and without any manipulation of the thyroid gland. The VN was exposed in the carotid sheath and then stimulated using a monopolar probe at a precisely defined point above the clavicle, using anatomical landmarks. Results: In total, 136 women with a mean age of 40 years (range 18–74) and 36 men with a mean age of 42 (range 21–66), demonstrating 270 nerves at risk, were included in the analysis. Indications for surgery were malignancy in 70 cases, toxic goiter/Graves in 23 cases, retrosternal goiter in 21, and symptomatic multinodular goiter in 64 cases. Of these, 100 patients received a total thyroidectomy, 46 received a right lobectomy, and 24 received a left lobectomy only. For a total thyroidectomy, the median skin-to-skin surgery duration was 52 min (range 24–104 min) and the median hospital stay was 2 days (range 1–4 days). In 4 cases (4/146; 2.74%) the pre-dissection stimulation of the vagal nerve (VN1) at the ADNM’s precisely defined point did not create any signal or proper EMG-curve that indicated the existence of the non-RLN. Proximal dissection of the right VN at a precisely defined point by the ADNM’s level of incisura of the larynx created a positive signal. The separation point of the right non-RLN from the VN was discovered in all four patients. The postoperative video-laryngoscopy confirmed bilateral mobile vocal cords in all cases. Conclusions: Following the ADNM protocol during thyroid surgery minimizes the risk of a non-laryngeal nerve injury and prevents voice dysfunction. Full article

The bilateral axillo-breast approach (BABA) for robot-assisted thyroidectomy has some advantages over other minimally invasive thyroidectomies. However, some people do not consider this as a minimally invasive thyroidectomy because of the wider surgical skin flap. Thus, we devised mini-flap BABA robot-assisted thyroidectomy and analyzed the postoperative outcomes. The clinical records of 44 patients undergoing BABA robot-assisted thyroidectomy using a conventional flap or mini-flap were evaluated retrospectively. There were no significant group differences in clinicopathological characteristics. The operating and flap making times were shorter in the mini-flap group (206.18 ± 31.09 vs. 178.90 ± 34.43 min, p = 0.009; 38.85 ± 2.73 vs. 32.21 ± 8.62 min, p = 0.003, respectively). The total drainage amount was smaller in the mini-flap group (196.57 ± 81.40 vs. 150.74 ± 40.80 mL, p = 0.027). The numeric rating scale score and number of analgesics were lower at 2 h postoperatively in the mini-flap group (5.52 ± 0.87 vs. 4.57 ± 1.31, p = 0.006; 0.95 ± 0.22 vs. 0.65 ± 0.49, p = 0.012, respectively). There was no significant group difference in immediate oncological outcomes (p = 1.000). Mini-flap BABA robot-assisted thyroidectomy minimized the surgical flap and improved surgical outcomes. Therefore, it is a form of minimally invasive thyroidectomy. However, long-term follow-up of oncological outcomes is needed. Full article

(1) Background: The incidence of papillary thyroid cancers is increasing. Papillary neoplasm metastasizes to the central and lateral lymph nodes of the neck. The recurrence rate is less than 30%. The gold standard of treatment for lymph node recurrences is surgery, but surgery is burdened by a high rate of complications. Therefore, laser ablation of recurrent lymph nodes has been recognized as an alternative treatment with minimal invasiveness, a low complication rate and a curative effect. (2) Methods: We analyzed 10 patients who underwent a total thyroidectomy and metabolic radiotherapy and who developed a lymph node recurrence in the laterocervical compartment in the following 12–18 months. (3) Results: Patients developed lymph node recurrence at IV and Vb levels in 70% and 30% of cases, respectively. All patients were treated with a single laser ablative session. Hydrodissection was performed in all patients. The energy delivered was 1120 ± 159.3 Joules and 3–4 Watts in 362 ± 45.7 s. No complications were reported. All patients underwent a 6-month follow-up. A volumetric reduction of 40.12 ± 2.2%, 49.1 ± 2.13% and 59.8 ± 3.05%, respectively at 1-, 3- and 6-months of follow-up was reported. (4) Conclusions: At 6 months, a fine needle aspiration was performed, which was negative for malignant cells and negative for a dosage of Thyroglobulin in eluate. The laser ablation is an effective alternative to surgical treatment. Full article

Background: The diagnosis of thyroid cancer is continuously increasing and consequently the amount of thyroidectomy. Notwithstanding the actual surgical skill, postoperative hypoparathyroidism still represents its most frequent complication. The aims of the present study are to analyze the rate of postoperative hypoparathyroidism after thyroidectomy, performed for cancer by a single first operator, without any technological aid, and to compare the data to those obtained adopting the most recent technological adjuncts developed to reduce the postoperative hypoparathyroidism. Methods: During the period 1997–2020 at the Endocrine Surgery Unit of the Department of Clinical and Experimental Medicine of the University of Florence, 1648 consecutive extracapsular thyroidectomies for cancer (401 with central compartment node dissection) were performed. The percentage of hypoparathyroidism, temporary or permanent, was recorded both in the first period (Group A) and in the second, most recent period (Group B). Total thyroidectomies were compared either with those with central compartment dissection and lobectomies. Minimally invasive procedures (MIT, MIVAT, some transoral) were also compared with conventional. Fisher’s exact and Chi-square tests were used for comparison of categorical variables. p < 0.01 was considered statistically significant. Furthermore, a literature research from PubMed^® has been performed, considering the most available tools to better identify parathyroid glands during thyroidectomy, in order to reduce the postoperative hypoparathyroidism. We grouped and analyzed them by technological affinity. Results: On the 1648 thyroidectomies enrolled for the study, the histotype was differentiated in 93.93 % of cases, medullary in 4% and poorly differentiated in the remaining 2.06%. Total extracapsular thyroidectomy and lobectomy were performed respectively in 95.45% and 4.55%. We recorded a total of 318 (19.29%) cases of hypocalcemia, with permanent hypoparathyroidism in 11 (0.66%). In regard to the literature, four categories of tools to facilitate the identification of the parathyroids were identified: (a) vital dye; (b) optical devices; (c) autofluorescence of parathyroids; and (d) autofluorescence enhanced by contrast media. Postoperative hypoparathyroidism had a variable range in the different groups. Conclusions: Our data confirm that the incidence of post-surgical hypoparathyroidism is extremely low in the high volume centers. Its potential reduction adopting technological adjuncts is difficult to estimate, and their cost, together with complexity of application, do not allow immediate routine use. The trend towards increasingly unilateral surgery in thyroid carcinoma, as confirmed by our results in case of lobectomy, is expected to really contribute to a further reduction of postsurgical hypoparathyroidism.

Introduction: Thyroid peroxidase (TPO) deficiency is the most common enzymatic defect causing congenital hypothyroidism (CH). We aimed to characterize the long-term outcome of patients with TPO deficiency. Methods: Clinical and genetic data were collected retrospectively. Results: Thirty-three patients with primary CH caused by TPO deficiency were enrolled. The follow-up period was up to 43 years. Over time, 20 patients (61%) developed MNG. Eight patients (24%) underwent thyroidectomy: one of them had minimal invasive follicular thyroid carcinoma. No association was found between elevated lifetime TSH levels and the development of goiter over the years. Conclusions: This cohort represents the largest long-term follow up of patients with TPO deficiency. Our results indicate that elevated TSH alone cannot explain the high rate of goiter occurrence in patients with TPO deficiency, suggesting additional factors in goiter development. The high rate of MNG development and the risk for thyroid carcinoma indicate a need for long-term follow up with annual ultrasound scans. Full article

Thyroid cancer in children is very uncommon. For pediatric thyroid cancer, robotic surgery has served as a minimally invasive surgical alternative to conventional open surgery. Our study aimed to evaluate the results of robotic versus open surgical treatment for patients with thyroid cancer younger than 20 years of age at the time of diagnosis. This retrospective review included 161 pediatric patients who underwent robotic transaxillary or conventional open thyroidectomy at our institution from 2008 to 2019. Of these patients, 99 comprised the robotic group and 62 the open group. Patient demographics, surgical outcomes, and disease-free survival rates were compared between the two groups. Patients in the open group were more likely to have advanced stage diseases with a larger tumor size and higher tumor-node-metastasis stage than those in the robotic group. Operation time and follow-up period were similar in both groups. Patients in the robotic group had a lower rate of postoperative complications and a shorter length of hospital stay, but they also had a lower average number of retrieved central lymph nodes. However, there were no significant between group differences in recurrence rates and disease-free survival. In the hands of an experienced surgeon, robotic thyroidectomy is a feasible and safe option for pediatric patients. Full article
