RESUMEN
BACKGROUND: TIR3B thyroid nodules are considered to be at risk of malignancy (15-30%) but guidelines recommend conservative surgery with lobectomy with primary diagnostic porpoise. Risk stratification mainly based on ultrasound, elastography and genetic mutations usually may influences the surgical approach. METHODS: We retrospectively analyzed 52 cases of TIR3B underwent between 2015 and 2017 total thyroidectomy (TT) and lobectomy (L), focusing mainly on the observed rate of malignancy. Chi-squared test and Fisher's exact probability test were used for analysis, considering a P values less than 0.05 as significant. RESULTS: Out of 52 patients 49 underwent TT and 3 L. In TT group a multinodular goiter was associated in 67.3% of patients. Malignancy rate was 81.6 and 33.3% respectively after TT and L (P 0.003). Multicentric and contralateral tumors were detected respectively in 36.7% and in 32.6% of patients underwent TT. No main post-operative complications were registered. CONCLUSIONS: Ultrasound and elastography are useful to define within the TIR3B group those lesions at higher risk and therefore requiring a more radical approach. TT seems an appropriate approach to TIR3B lesions, especially in multinodular goiter, considering the incidence of malignancy with probably higher rate than previously reported.

BACKGROUND: Secondary hyperparathyroidism in elderly fragile patients presents clinical difficulties due to severity of symptoms and related comorbidity. The optimal surgical approach for this group of patients is still debated. AIM: The aim of the study was to define the optimal technique of parathyroidectomy in elderly patients with secondary hyperparathyroidism. METHODS: Retrospective analysis in a series of 253 patients including 35 elderly individuals at a single institution was carried out. Postoperative parathyroid hormone decrease, surgical complications and symptoms control were analyzed for all patients in relation to the types of parathyroidectomy performed. RESULTS: In elderly patients, total parathyroidectomy was the most used approach. Subtotal parathyroidectomy was mostly reserved for younger patients suitable for kidney transplantation. No elderly patients treated with total parathyroidectomy were autotransplanted. No significant difference in surgical complications was observed between younger and elderly patients and considering the different procedures. Adequate symptom control after surgery was achieved in almost 90% of patients. A limited rate of recurrence requiring repeat surgery was observed only after subtotal parathyroidectomy. DISCUSSION: Considering the features of all types of parathyroidectomy, very low recurrence rate, contained postoperative hypocalcemia and limited complications following total parathyroidectomy, might represent specific advantages for elderly patients. CONCLUSIONS: Total parathyroidectomy without parathyroid transplantation is safe for elderly patients with secondary hyperparathyroidism and a good alternative to the well-established total parathyroidectomy with autografting.

BACKGROUND: Hemostasis during thyroidectomy is essential; however, the safest, most efficient, and most cost-effective way to achieve this is unclear. This randomized, multicenter, single-blind, prospective study evaluated the efficacy and safety of using different hemostatic approaches in patients undergoing total thyroidectomy. METHODS: Patients aged ≥18 to 70 years were randomized to Floseal + a harmonic scalpel (HS), Floseal alone, HS alone, or standard total thyroidectomy. Primary endpoint was 24-hour drain output. Secondary endpoints included surgery duration and complications. RESULTS: Two hundred and six patients were randomized to Floseal + HS (n = 52), Floseal alone (n = 54), HS alone (n = 50), and standard total thyroidectomy (n = 50). The 24-hour drain output was lower in the Floseal + HS group compared with standard thyroidectomy. Floseal + HS also had a shorter surgery time (P < .0001) versus the other 3 treatments. CONCLUSION: Floseal + HS can be effective at reducing postsurgical drain output and provides a complementary hemostatic approach in patients undergoing total thyroidectomy.

BACKGROUND: Phyllodes tumors are biphasic fibroepithelial neoplasms of the breast. While the surgical management of these relatively uncommon tumors has been addressed in the literature, few reports have commented on the surgical approach to tumors greater than ten centimeters in diameter - the giant phyllodes tumor. CASE REPORT: We report a case of a 45-year-old woman who presented with a large lump in her right breast, involvement of multiple ipsilateral axillary lymph nodes and pectoralis major muscle. Clinical findings and cytologic examination (fine-needle aspiration) were suggestive of cystosarcoma phyllodes and we discuss the techniques utilized for pre-operative diagnosis, tumor removal, and breast reconstruction. A review of the literature on the surgical management of phyllodes tumors was performed. CONCLUSION: Management of the phyllodes tumor presents the surgeon with unique challenges. The majority of these tumors can be managed by simple mastectomy. In our case clinical findings and cytologic examination (fine-needle aspiration) were suggestive of cystosarcoma phyllodes, for which the patient underwent a modified radical mastectomy. Postoperative radio therapy was given to the loco regional area. KEYWORDS: Immediate reconstruction, Phylloides tumors, Post-operative radio therapy, Radical surgery.

INTRODUCTION: Breast metastases although rare are challenging for diagnostic difficulties and management. Treatment differs according to morphological, immunophenotipycal and biologic features of the primary tumor and their general behaviour is extremely different compared to primary breast cancer. The most frequent primary tumors include melanoma, lymphomas, gynecological, pulmonary, head and neck, gastroenteric and urinary tract cancers. Patient's prognosis is poor being generally associated to disseminated systemic disease with limited survival despite the effects of systemic treatment. PATIENTS AND METHODS: We report the analysis of the diagnostic and therapeutic approach on the institutional experience of four cases of breast metastases originating from melanoma, pulmonary adenocarcinoma and differentiated thyroid carcinomas. CONCLUSIONS: The management of breast secondarisms requires focused diagnosis and evaluation in order to provide an adequate treatment with a multidisciplinary approach especially when the primary tumor is unknown. KEY WORDS: Breast metastases, Melanoma, Pulmonary, Thyroid.

Lateral neck dissection (LND) leads to a significant morbidity involving accessory nerve injury. Modified radical neck dissection (MRND) aims at preservation of the accessory nerve, but patients often present with negative functional outcomes after surgery. The role of neuromonitoring (IONM) in the prevention of shoulder syndrome has not yet been defined in comparison to nerve visualization only. We retrospectively analyzed 56 thyroid cancer patients who underwent MRND over a period of six years (2015-2020) in a high-volume institution. Demographic variables, type of surgical procedure, removed lymph nodes and the metastatic node ratio, pathology, adoption of IONM and shoulder functional outcome were investigated. The mean number of lymph nodes removed was 15.61, with a metastatic node ratio of 0.2745. IONM was used in 41.07% of patients, with a prevalence of 68% in the period 2017-2020. IONM adoption showed an effect on post-operative shoulder function. There were no effects in 89.29% of cases, and temporary and permanent effects in 8.93% and 1.79%, respectively. Confidence intervals and two-sample tests for equality of proportions were used when applicable. Expertise in high-volume centres and IONM during MRND seem to be correlated with a reduced prevalence of accessory nerve lesions and limited functional impairments. These results need to be confirmed by larger prospective randomized controlled trials.
RESUMEN
Medullary thyroid carcinoma is a highly malignant and progressive disease. Surgery is the only effective treatment. Calcitonin is a significant marker for medullary thyroid carcinoma, and due to its sensitivity it represents a useful tool for the follow-up. The outcome of patients affected by medullary thyroid carcinoma depends on tumor size, lymph node involvement, and adequacy of primary surgical management. In the present study, the authors reviewed their own experience in the cure of medullary thyroid carcinoma. Forty-one patients operated for sporadic medullary thyroid carcinoma were included. Indications for surgery, inclusive of lymphectomy techniques, timing of redo surgery, and the meaning of calcitonin levels in highlighting disease are extensively discussed. Patients with elevated calcitonin levels and favorable outcome are considered, together with the various diagnostic tools to be employed during patient workup.

RESUMEN
BACKGROUND: Intrathyroid metastases (ITM) are rare and usually have a dismal prognosis. The aim of this study was to detect which neoplasms metastasize most often to the thyroid gland, their clinical features and treatment options. MATERIALS AND METHODS: Retrospective analysis of clinical files of 17,122 patients submitted to surgery for thyroid disease between 1995 and 2005. Twenty-five patients (median age 61 years) were affected by ITM. RESULTS: The site of the primary tumor was: kidney (15), lung (4), colon (3), breast (1), melanoma (1), and unknown in 1 patient. Ten patients (40%) complained of preoperative symptoms, in the others, thyroid involvement was incidentally discovered during the follow-up for the primary cancer. Twenty patients (80%) underwent total thyroidectomy, 3 received thyroid lobectomy and 2 palliative procedures. Morbidity was 16%, mortality was nil. The median follow-up was 24 months. CONCLUSION: ITM should always be suspected in any patient with a previous history of malignancy. Fine-needle agobiopsy (FNAB) with immunohistochemical stains may help in preoperative workup. A long delay between the primary tumor and the recurrence warrants surgery and total thyroidectomy seems to be the treatment of choice because of the multifocality of metastasis to the thyroid gland.

Cancer originates from a single cell which, through the acquisition of mutations in genes for key growth and survival factors, undergoes clonal expansion. Study of the genome allowed the detection of genes whose mutation is involved in tumour formation. In detail, in most thyroid neoplasms we are now able to identify the genes which cause cancer initiation. Moreover, correlations between mutations and clinico-pathological features of the tumours have been revealed. Thus, the genetic study of tumours is not anymore only a scientific curiosity, but a useful tool for the formulation of the more efficacious therapeutic and follow-up strategies. In this review we will summarize the more recent molecular medicine acquisitions in the thyroid cancer field and will describe their present and eventually future impact on the activity of the endocrine surgeon.

The incidence and possible association of inferior laryngeal nerve and sympathetic anastomotic branch anomalies were evaluated in this study. Non-recurrent inferior laryngeal nerves stem from vascular anomalies involving the right subclavian artery and aortic arches during embryological development. These anomalies usually have no functional consequences (except for occasional dysphagia), but are potentially dangerous during thyroid surgery, occurring in about 1% of cases. Sympathetic-inferior laryngeal anastomotic branches are described in about 1.5% of cases, and may be confused with non-recurrent inferior laryngeal nerves. 1473 patients submitted to total thyroidectomy for benign disease over the period 2001-2006 were evaluated. Four non-recurrent inferior laryngeal nerves (incidence: 0.27%) and 11 sympathetic-inferior laryingeal anastomotic branches (incidence: 0.74%) were observed. Out of a total of 25 definitive inferior laryngeal nerve lesions, 1 occurred in a case of non-recurrent inferior laryngeal nerve. Awareness of the anatomical anomalies described and accurate surgical technique, including a constant search for the inferior laryngeal nerve, are the requirements for identification of non-recurrent inferior laryngeal nerves and sympathetic-inferior laryngeal anastomotic branches. During the pre-operative workup, ultrasonographic study of the right subclavian artery may be advisable in order to rule out alterations of its origin and course.

Surgical resection is the only curative treatment option for local recurrence of well differentiated thyroid cancer. In our experience, we found that intraoperative ultrasonography can be of significant help in facilitating the localisation and complete resection of lesions. From 2005 to 2006, 12 patients with well differentiated thyroid tumour recurrences underwent intraoperative ultrasonography. Recurrences were easily identified and resected in all patients. Postoperative thyreoglobulin was not detected. Intraoperative ulrasonography can be of significant help in the identification of well differeniated thyroid tumour recurrences, particularly when the cancer is smaller than 10 mm in diameter, and can facilitate a more radical excision of the tumour.

This study presents the results of surgery in the elderly for primary hyperparathyroidism (PHPT) from a single institution's experience. We retrospectively analyzed 898 cases of surgically treated PHPT, divided into two groups: 135 elderly patients (A) and 763 patients younger than 65 years (B). PHPT was symptomatic in 68.8 per cent patients in group A and in 81.6 per cent in group B. Unilateral temporary recurrent laryngeal nerve palsy was observed in 0.9 per cent in group A and 0.1 per cent in group B (P > 0.05). No cervical hematomas, mortality or major cardiovascular, neurological, respiratory or metabolic postoperative complications were registered. All the patients evaluated at one year had improvement in the quality of life, with increase of bone mineral density (BMD) in 85.6 per cent and 79.8 per cent of patients in groups A and B, with no significant differences between symptomatic and asymptomatic patients. Parathyroidectomy in elderly PHPT patients is safe, with rate of morbidity similar to what observed in younger individuals. Further investigations are recommended to confirm the role of surgery as an effective approach in elderly PHPT patients.

BACKGROUND: Medullary thyroid carcinoma is an aggressive tumor and presents with significant morbidity and mortality and a high rate of lymph node metastases. The combination of total thyroidectomy and cervical lymphadenectomy is the essential treatment for those patients presenting with cervical lymph node metastases. MATERIALS AND METHODS: A retrospective analysis of 117 patients operated for medullary thyroid carcinoma over a period of 15 years at a single institution. Surgical complications and calcitonin levels were noted. RESULTS: Nodal metastases were detected in the central compartment in 72.6% patients. Positive lymph nodes were detected in the lateral compartment of 34 patients who had undergone ipsilateral dissection and in all 10 patients of those with bilateral surgery. We found 3 cases of unilateral transient recurrent laryngeal nerve palsy, 15 cases of temporary hypoparathyroidism, a permanent accessory nerve lesion and a case of chylous fistula. Normalization of post-operative calcitonin was found in 82.6% and of patients who underwent total thyroidectomy and central neck dissection alone compared to 35.4% in those with ipsilateral and bilateral neck dissection. CONCLUSIONS: Total thyroidectomy and cervical lymphadenectomy planned on the ultrasound preoperative study and on the calcitonin level represent the standard of treatment for medullary thyroid carcinoma.

Diagnostic-therapeutic itineraries and treatment profiles are instruments of clinical management. The authors report on their experience with the experimental creation of such itineraries in thyroid nodular pathology. These are the fruit of collaboration between the management team, endocrinological surgeons, and the hospital computer staff. The drawing-up of guidelines in the hospital setting allows the systematic organisation of clinical activities to be accomplished in the health-care facility, quantifying costs for all diseases in order to be able to plan and implement changes in resources and staff utilisation. Application of the method, in addition, helps to develop a common language among hospital doctors and nurses, facilitates proper communication with patients, and ensures adequate patient information regarding the clinical itinerary the patient will have to take for his or her condition.

The Diagnostic and Therapeutic Programs are instruments of clinical management. The authors report on their experience with the construction of a Diagnostic and Therapeutic Program in the field of breast cancer. This is the result of collaboration between the Breast Unit, an administrative team and a computer team at the "S. Maria" Hospital in Terni. The implementation of the guidelines in the hospital setting makes it possible to systematise the clinical activities, to quantify the economic impact for each disease, and to plan any changes in the use of resources. The application of this method, moreover, makes it possible to develop a common language between medical and nursing staff which can be easily understood by the patients and to inform patients adequately with regard to the diagnostic and therapeutic program they will have to comply with for their respective conditions.

The minimally invasive approach to parathyroid surgery is considered an efficient alternative to traditional cervicotomy when the pre-operative diagnostic work-up indicates a single parathyroid adenoma. Imaging techniques (ultrasound, SPECT), on the one hand, and intraoperative diagnostic techniques (radio-guided surgery, intraoperative parathyroid hormone assay), on the other, contribute to the success and development of specialized centres which prefer to use this type of surgery. The postoperative pain control and aesthetic results achieved with these techniques are today the main subjects of interest in the minimally invasive approach.

BACKGROUND/AIM: Hypoparathyroidism is the most significant morbidity after neck dissection for thyroid cancer. Addition of lateral neck dissection (ND) to central ND combined with total thyroidectomy (TT) increases the risk of postoperative hypoparathyroidism compared to TT plus central ND. The aim of this study was to verify if a modified procedure and different access to the neck for lateral ND may improve safety. PATIENTS AND METHODS: In 62 patients with papillary thyroid cancer (PTC) undergoing TT plus central and lateral ND between 2010 and 2013, lateral ND was performed as first step approaching the neck via extrathyroideal space. Calcium in serum and parathormone (PTH) were determined preoperatively, intraoperatively and during the follow-up. RESULTS: Twenty patients (32%) developed postoperative hypocalcemia. Calcium levels and PTH completely recovered for 58 out of 62 patients from 3 to 6 months after surgery. After a mean of 12 months' follow-up, only four patients (6.5%) had developed permanent hypoparathyroidism. The incidence of parathyroid complication after TT plus central ND and lateral ND did not differ from postoperative hypoparathyroidim after TT plus central ND. CONCLUSION: The presented surgical procedure may provide a better outcome in terms of parathyroid morbidity.

INTRODUCTION: Thoracic duct fistula at the cervical level is a severe but rare complication following thyroid surgery, particularly associated to lateral dissection of the neck and to mediastinal goiter. METHODS: we retrospectively analyzed chylous fistulas observed in a cohort of 13.224 patients underwent surgery for thyroid disease since 1986 to 2014, in the Unit of Endocrine Surgery, S. Maria University Hospital, Terni, Italy. RESULTS: We observed 20 cases of chylous fistula. Thirteen patients underwent primary surgery in our institution while the remaining 7 cases had been referred to our Department from other hospitals for an already diagnosed lymphatic leak. Surgical procedures carried out included total thyroidectomy for mediastinal goiter in 4 patients, total thyroidectomy for cancer in 2 patients, unilateral functional lymphadenectomy in 11 patients and bilateral in 3. Intraoperative repair was carried out in 4 cases. Of the remaining 16 cases, 4 of the 6 fistulas with low flow leakage healed in about 30 days of conservative treatment, 2 cases instead required surgical repair. All 10 patients with "high-flow" fistula underwent surgery. Despite surgery was performed later, postoperative course in patients with late surgical repair is similar to what observed in those patients with early surgical repair. Both groups underwent cervical drainage removal in post-operative day 4. CONCLUSION: Healing of a cervical chylous fistula can be achieved by conservative medical therapy (nutritional and pharmacological) but in case of therapeutic failure with rapid decrease of general condition, the surgical approach is necessary. In our experience, duct ligation after unsuccessful conservative treatment, is the only resolutive treatment.

INTRODUCTION: Aim of this study is to analyze outcome and the decision making process to approach airway invasion by thyroid tumors. METHODS: Retrospective study of 30 years experience in thyroid surgery for cancer invading airway. Clinical records, surgical and pathology reports have been analyzed to assess which principles and procedural details are significant to facilitate efficient diagnosis, staging and treatment. Medical therapy was not evaluated. RESULTS: Out of a consecutive series of 2165 thyroid cancer patients, T4a cancers are 303 (14%). Airway invasion was found in 141 (6.5%) cases. Well-differentiated pattern was determined in 110 (78%) while other histology was reported in 31 (22%). Airway-related symptoms have been recorded in 111 (78%) patients. Flexible bronchoscopy was performed in all patients. Rapidly evolving disease or non-resectable airway was found in 105 (74.5%) cases. Permanent tracheotomy was performed in 43 (30.5%) cases, airway lumen restoration with or without stenting in 39 (27.7%), laryngectomy in 8 (5.7%), segmental airway resection and reconstruction in 28 (19.9%). Perioperative mortality was recorded after palliative treatment only. In resected patients, completely radical surgery was not always achievable. All patients with positive margin after resection underwent adjuvant treatment and showed comparable survival to radical surgery patients after 5 years. Tumor relapse occurred in 8 (28.6%) cases (distant or locoregional). Patients with unresectable disease require treatment for symptoms relief but survival is poor. CONCLUSION: Although some patients are currently referred with a severely advanced disease, the indication for tracheotomy, salvage procedures or supportive care has decreased over time. Resection is feasible for differentiated tumors with an overall good outcome.
