The outbreak of the COVID-19 pandemic has led to a disruption of surgical care. The aim of this multi-centric, retrospective study was to evaluate the impact of the pandemic on surgical activity for thyroid disease among the Italian Units of Endocrine Surgery. Three phases of the pandemic were identified based on the epidemiological situation and the public measures adopted from the Italian Government (1st phase: from 9th March to 3rd May 2020; 2nd phase: from 4th May to 14th June; 3rd phase: from 15th June to 31st). The patients operated upon during these phases were compared to those who underwent surgery during the same period of the previous year. Overall, 3892 patients from 28 Italian endocrine surgical units were included in the study, 1478 (38%) operated upon during COVID-19 pandemic, and 2414 (62%) during the corresponding period of 2019. The decrease in the number of operations was by 64.8%, 44.7% and 5.1% during the three phases of COVID-19 pandemic, compared to 2019, respectively. During the first and the second phases, the surgical activity was dedicated mainly to oncological patients. No differences in post-operative complications were noted between the two periods. Oncological activity for thyroid cancer was adequately maintained during the COVID-19 pandemic.
The diagnosis of incidental thyroid carcinoma in patients submitted to thyroidectomy for a benign disease is quite frequent. A retrospective analysis was performed on 455 patients submitted to surgical intervention in order to establish the incidence of this kind of carcinoma. Two hundred fifty-six patients (56%) were affected by benign disease (176 multinodular goiter, 12 uninodular goiter, 1 Plummer disease and 67 Basedow disease) and 202 (44%) by carcinoma. In 28 of 256 patients (11%), affected by benign disease, occurred a histological diagnosis of thyroid carcinoma, (10 papillary carcinoma, 1 follicular carcinoma, 29 papillary carcinoma follicular variant). In this study it's considered incidental thyroid carcinoma the one occurred in patients who never underwent Fine Needle Aspiration (FNA) and there were no suspicious features in all exams that may suggest the presence of carcinoma. Twenty-three of the 40 incidental carcinoma (57.5%) were microcarcinomas. Ten patients had a sincronous carcinoma. Actually, these patients are still in a follow up program and no recurrency of disease is occasionally observed. This study shows that the only way to put doubts on the real benignity of the disease is the fine needle aspiration; there are no other instruments that could identify the occurrence of the carcinoma. Moreover in the majority of cases the incidental carcinoma is a microcarcinoma, it doesn't reach significant volume, may be not centered by a FNA, but in most cases it's not really biologically aggressive.
Background: Robotic thyroidectomy by transaxillary approach (RATS) is regarded as a feasible and safe alternative procedure in selected patients with benign disease or thyroid cancer of low risk, facilitating thyroidectomy with respect to conventional endoscopic approach and offering improved cosmetic results. The Da Vinci Xi surgical system (Intuitive Surgical, Sunnyvale, CA, USA) presents technical advantages over its previous generations, including overhead docking, more compact robotic arms, extended range of motion, and ability for camera to be docked in any arm. This construct supports dissection in smaller spaces with less arm interference and improved view. We present an initial experience of RATS on DVSS Xi in an academic Centre in Italy. Methods: We conducted a prospective observational study, involving patients with thyroid disease and treated between April 2016 and January 2018. A modified thyroidectomy retractor (Modena retractor, CEATEC Medizintechnik, Germany) was used to lift a musculocutaneous flap and operate gasless. Instrument placement was recorded for each procedure. Each procedure description was broken down into three phases, creation of working space, machine docking with instrument positioning and endoscopic operating technique. Duration of cases was recorded. Patients selected were young women, BMI < 30, thyroid nodule < 5 cm, cytology TIR2 to TIR4 (TIR4:only nodules < 1 cm diameter). Results: Twelve RATS were performed within the learning curve for the robotic technique, 10 lobectomies and 2 total thyroidectomies. No patients required reintervention. Mean duration of surgery was 198.9 min for lobectomy and 210 for thyroidectomy. The same surgical team performed all procedures. No patients presented surgery-related complications, mean stay was 3 days. Decrease in operating time was observed after 8 cases along with more precise preparation of working space. Four arms were used in the first 10 procedures then only three. No recurrent laryngeal nerve dysfunction, no seroma or haematoma were recorded. One patient had transient hypocalcaemia after total thyroidectomy. Conclusions: Since the early phases of a preliminary experience RATS appeared a safe alternative to open thyroidectomy. Uptake of technique was quick on Xi platform with few technical tweaks over techniques described for Si machines.
BackgroundClusterin (CLU) is a ubiquitous multifunctional factor involved in neoplastic transformation. The CLU transcript variants and protein forms play a crucial role in balancing cells proliferation and death.MethodsWe investigated the regulation of CLU transcript variants expression in an in vivo model system consisting of both neoplastic tissues and fine needle aspiration biopsy (FNAB) samples isolated from patients undergoing thyroidectomy.ResultsThe immunohistochemical analyses showed an overall CLU up-regulation in papillary carcinoma. A specific CLU2 transcript variant increase was registered using qPCR in papillary carcinomas while CLU1 decreased. In addition, the analysis of CLU transcripts expression level showed an increase of the CLU2 transcript in the TIR 3 patients with histologically confirmed thyroid cancer.ConclusionsOur results suggest the existence of a specific alteration of CLU2:CLU1 ratio towards CLU2, thus providing the first circumstantial evidence for the potential use of CLU transcript variants as effective biomarkers for a more accurate assessment of the so called “indeterminate” thyroid nodules.
