RESUMO
BACKGROUND: Laparoscopic adrenalectomy is the gold standard for adrenal tumor; however, robotic adrenal surgery has gained interest recently. For minimally invasive surgeries, we first reported on robotic adrenalectomy using a single-port access performed using the da Vinci multi-arm robotic system (RA-SA) in 2011. Since its introduction in 2018, we first performed robotic adrenalectomy using the da Vinci SP robotic system in 2020. OBJECTIVE: We aimed to introduce the novel single-port robotic system (RA-SP) for adrenalectomy and evaluate its technical feasibility by comparing it with the surgical outcomes of patients who underwent robotic adrenalectomy using the RA-SA. METHODS: Eight patients who underwent robotic adrenalectomy using the RA-SP from February 2020 to June 2021 were compared with 11 patients who underwent RA-SA from 2011 to 2015 by a single surgeon. RESULTS: The two groups were similar in age, sex, body mass index, type of operation, and final pathologic diagnosis. Despite no significant differences, RA-SP resulted in moderately less mean operation time, estimated blood loss, and length of hospitalization. CONCLUSIONS: The Da Vinci SP robotic system is a novel, safe, and feasible technique to improve the convenience of operation and cosmetic effect for adrenalectomy.

BACKGROUND: Differentiated thyroid carcinoma with lateral neck lymph node metastasis requires aggressive operative intervention, including lateral neck dissection. Although several robotic approaches have made precise surgery for thyroid cancer possible, few centers have expanded the technique for application to lateral neck dissections. This study aimed to demonstrate the technical feasibility, cosmetic effectiveness, and safety of robotic transaxillary lateral neck dissection (RTLND) using the da Vinci system. METHODS: From January 2008 to July 2019, 500 patients diagnosed with thyroid cancer with lateral neck node metastasis underwent RTLND. The clinicopathologic characteristics and surgical outcomes were retrospectively reviewed. RESULTS: All operations were performed successfully without open conversion. As the primary operation for thyroid cancer, 476 (95.2%) patients underwent unilateral or bilateral RTLND, including robotic total thyroidectomy. The remaining 24 patients (4.8%), all of whom had a recurrence, also underwent RTLND with additional procedures, if needed. The mean operation time for the 500 operations was 293.71 ± 67.22 min. Only five cases had recurrence and required further treatment. CONCLUSIONS: RTLND is technically feasible and safe through the precise manipulation of robotic instruments. While this method is thorough and provides safe and effective surgical outcomes, it also offers the additional advantage of being minimally invasive.

BACKGROUND: This study aims to report the results of a pioneering clinical study using the single-port transaxillary robotic thyroidectomy (START) for 200 patients with thyroid tumor and to introduce our novel two-step retraction method. METHODS: START was performed on consecutive 200 patients using the da Vinci Single-Port (SP) robot system from January 2019 to September 2020 at the Yonsei University Health System, Seoul, Korea. The novel two-step retraction technique, in which a 3.5 cm long incision is made along the natural skin crease, was used for the latter 164 patients. The surgical outcome and invasiveness of the SP two-step retraction method were analyzed. RESULTS: Among the 200 cases who underwent START, 198 were female and 2 were male, with a mean age of 34.7 (range: 13-58 years). Thyroid lobectomy was performed for 177 patients and total thyroidectomy was performed for 23 patients. Ten patients had benign thyroid nodules, whereas the other 190 had thyroid malignancy. The mean body mass index (BMI) was 22.2 ± 3.7 kg/m2 (range: 15.9-37.0 kg/m2). All of the operations were performed successfully without any open conversions, and patients were discharged on postoperative day 3 or 4 without significant complication. The mean operative time for thyroid lobectomy with the two-step retraction method was 116.69 ± 23.23 min, which was similar to that in the conventional robotic skin flap method (115.33 ± 17.29 min). We could minimize the extent of the robotic skin flap dissection with the two-step retraction method. CONCLUSIONS: START is a practical surgical method. By employing the new two-step retraction method, we can maximize the cosmetic and functional benefits for patients and reduce the workload fatigue of surgeons by increasing robotic dependency.

BACKGROUND: Despite the increase in experience and understanding of robotic thyroidectomy, its application for Graves' disease (GD) remains controversial. This study aimed to assess the safety and feasibility of robotic transaxillary thyroidectomy (RTT) for GD in comparison with the conventional open thyroidectomy (open group: OG) approach. METHODS: A total of 192 patients who underwent surgical resection for GD were retrospectively reviewed. Among them, 51 patients underwent RTT and the remaining 141 patients were in the conventional OG. RESULTS: All robotic operations were performed successfully without open conversion. Patients who underwent RTT were significantly younger (P < 0.001) and predominantly of the female sex. Operative time was longer for RTT than for the OG (182.5 ± 58.1 vs. 112.0 ± 29.5; P < 0.001). The mean intraoperative blood loss was not statistically different between RTT and the OG (113.3 ± 161.6 vs. 95.3 ± 209.1, P = 0.223). The mean weight of the resected thyroid was reduced in those who underwent RTT compared with open thyroidectomy (P = 0.033). The overall complication rate for RTT and open thyroidectomy was not significantly different (33.3% vs. 22.7%, P = 0.135). In RTT, the most common complication was transient hypocalcemia (21%). Permanent hypocalcemia and recurrent laryngeal nerve injury occurred in only one patient in each group. The weight of the resected thyroid was not related to the incidence of complications in patients receiving RTT. CONCLUSIONS: Considering excellent cosmesis, findings of this study support the safety and feasibility of RTT. Nevertheless, it should be performed by expert surgeons with extensive robotic surgery experience.

BACKGROUND: Normocalcemic primary hyperparathyroidism (NPHPT) was first described in 2008. It is defined as consistently elevated serum parathyroid hormone (PTH) levels with normal serum calcium (sCa) concentration, after excluding secondary causes of PTH elevation. However, the exact definition and management strategy for NPHPT remain controversial. We retrospectively investigated the clinicopathological features and short-term outcomes of NPHPT patients. METHODS: A total of 280 patients who were surgically indicated for primary hyperparathyroidism (PHPT) at the Yonsei Severance Medical Center between 2015 and 2019 were included. Patients were classified according to preoperative PTH, corrected sCa, and ionized calcium (iCa) levels as follows: typical primary hyperparathyroidism (TPHPT, elevated PTH, sCa, and iCa, n = 158) and NPHPT (elevated PTH, normal sCa, n = 122). RESULTS: NPHPT was commonly seen in younger individuals (aged < 50 years, P = 0.025); nephrolithiasis and bone fractures were common. Preoperative PTH level was higher in the TPHPT group (P < 0.001). The NPHPT group had higher numbers of multiple parathyroid lesions (P = 0.004) that were smaller (P = 0.011). NPHPT patients were further divided into two subgroups according to iCa levels: the elevated (n = 95) and normal iCa (n = 27) groups. There was no significant difference between the two subgroups regarding symptoms and multiplicity of lesions. CONCLUSION: We found that NPHPT may be a heterogeneous disease entity of PHPT with high rates of multi-gland disease, which appears to be biochemically milder but symptomatic. Intraoperative PTH monitoring might help increase the surgery success rate. Moreover, the short-term outcomes of NPHPT after surgery did not differ from that of TPHPT.

OBJECTIVES: Due to the paucity of data and controversy regarding the preferred surgical approach for managing tertiary HPT, we sought to investigate the outcomes of different surgical approaches in managing this challenging disease. METHODS: We performed a multi-center retrospective study to include patients with tertiary HPT who underwent STPX or total parathyroidectomy with autotransplantation (TPX-A). RESULTS: One hundred five patients had kidney transplant, and 43 were on dialysis. In the kidney transplant group, 61 patients underwent STPX, and 44 for TPX-A. Patients' demographics were not significantly different (48.61â±â9.31 vs 47.95â±â12.73âyears, P = 0.759. The postoperative follow-up showed that the TPX-A cohort had a higher rate of hypoparathyroidism (N = 20, 45.45%) versus (N = 14, 22.95%) with the STPX cohort (P = 0.013). The cure among the TPX-A cohorts (84.09%) over the STPX cohort (73.77%) (P = 0.153). The long-term follow-up showed that the rate of developing temporary (N = 16, 41.03%) or permanent (N = 8, 20.51%) hypoparathyroidism was significantly higher among patients who underwent TPX-A over the patients who underwent STPX (N = 7, 17.95%), and (N = 4, 10.26%), respectively (P = 0.012). There was no statistical difference between the persistence (N = 3, 7.69%) or the recurrence (N = 2, 5.13%) of the HPT in the TPX-A cohort and the STPX cohort (N = 2, 5.13%). (N = 4, 10.26%), respectively, P = 0.644. CONCLUSIONS: To our knowledge, this is the largest multi-center study that compared different approaches for managing tertiary HPT. Showing that STPX is the better modality in patients diagnosed with tertiary HPT and had kidney transplants avoiding the risk of hypoparathyroidism.

BACKGROUND: The posterior retroperitoneoscopic approach (PRA) has been under attention as a method for resection of paraganglioma (PGL) for the past few years. However, only a few studies have explored the effectiveness and safety of the PRA for aortocaval and infrarenal PGL resection. METHODS: We designed this retrospective study to investigate the safety and effectiveness of the PRA for aortocaval and infrarenal PGL resection in a single center. We retrospectively reviewed the medical records of patients who underwent PRA for PGL resection at our medical center from January 2006 to March 2021. Eight patients were enrolled, of whom six had aortocaval PGL. We investigated the surgical outcomes of enrolled patients. RESULTS: The locations of the tumors in relation to the renal vein were: suprarenal in two (25.0%) patients, at the renal vein level in three (37.5%) patients, and infrarenal in three (37.5%) patients. The mean operative time of the enrolled patients was 101.5 ± 39.1 min. The mean postoperative stay was 3.5 ± 1.5 days, and the estimated blood loss was 31.3 ± 51.4 ml. There was one minor complication (chyle leakage), and two hypotensive events occurred during the surgery. Focusing on the results of the renal vein level and infrarenal PGL resection, the mean operative time, mean postoperative stay, and estimated blood loss of the patients were 109.2 ± 41.3 min, 3.5 ± 1.8 days, and 41.7 ± 56.4 ml, respectively. CONCLUSION: The PRA for aortocaval and infrarenal PGL resection is feasible and safe. Additional data analysis and long-term follow-up are needed in the future.

BACKGROUND: Thyroidectomy is the typical treatment for pediatric thyroid carcinoma; total thyroidectomy is commonly performed. We aimed to report our experience at a single tertiary institution and to evaluate the risk factors for recurrence, especially based on surgical extent, in pediatric patients with differentiated thyroid carcinoma (DTC). METHODS: A data of 94 pediatric patients who underwent thyroid surgery for DTC from January 1982 to December 2012 at Yonsei University Hospital (Seoul, Korea) were reviewed. The clinicopathologic features and surgical outcomes were retrospectively analyzed through complete chart reviews. RESULTS: The mean age was 16.6 ± 3.0 (range, 5-19) years. Fourteen patients had recurrence. Tumor size >2 cm (hazard ratio [HR], 14.241; p = 0.011) and positive lymph nodes (HR, 1.056; p = 0.039) were significant risk factors for disease-free survival (DFS) in multivariate analysis. In Kaplan-Meier analysis, a statistically significant difference was noted in the DFS according to tumor size 2 cm (p < 0.001). However, the DFS was not significantly different between the bilateral total thyroidectomy (BTT) and less than BTT groups (p = 0.215). CONCLUSIONS: BTT remains the treatment of choice in pediatric patients with DTC. Lobectomy may be considered for patients with limited disease, including those with tumor size <2 cm, no suspicious lymph nodes, intrathyroidal lesion, and no multifocal disease.

RESUMO
Background: Many studies have shown the operative feasibility and safety of robotic thyroidectomy. However, there is still a concern on the operative invasiveness of robotic thyroidectomy owing to the wide flap dissection. The aim of this study was to introduce our novel robotic technique, which can minimize the dissection extent using the da Vinci SP robotic system. Methods: Ten patients underwent robotic transaxillary thyroidectomy using the da Vinci SP robotic system between December 2018 and April 2019 at Yonsei University Hospital (Seoul, Korea). All procedures were performed successfully using the single-port robotic system. Results: All 10 patients were women and diagnosed with papillary thyroid carcinoma. The mean operative time was 148.7 ± 26.8 minutes. The mean operative time using the gasless method was shorter than that using the gas insufflation method (130.5 ± 14.1 vs 176.0 ± 12.8 minutes). All patients were discharged on the third day after operation without any complications. Conclusions: Robotic transaxillary thyroidectomy using the da Vinci SP robotic system is technically feasible and safe with a short length of incision, shorter than what earlier reported. To our knowledge, this is the first study to use a single-port robotic system for thyroidectomy. To verify the superior operative outcomes, further clinical trials are necessary.

BACKGROUND: Extensive extrathyroidal extension (ETE) has a significant role in the prognosis of papillary thyroid cancer (PTC) without distant metastasis, but its role in PTC with initial distant metastasis has never been studied. This study aimed to evaluate the prognostic significance of extensive ETE regarding disease progression, survival, and remission in PTC patients with initial distant metastasis. METHODS: This retrospective cohort study included PTC patients with initial distant metastasis who underwent total thyroidectomy with a median follow-up period of 6.7 years. The prognostic significance of extensive ETE was assessed in terms of time to tumor progression (TTP), cancer-specific survival (CSS), and cumulative incidence of remission with all-cause death as the competing event. RESULTS: The study enrolled 64 patients. Of these patients, 21 (32.8%) had extensive ETE, which was associated with a shorter TTP (adjusted hazard ratio [HR], 4.10; p = 0.015) and a lower CSS rate (p = 0.002, log-rank), particularly for patients 55 years of age or older with stage 4b disease (10-year CSS rate: 33.3% in those with and 92.3% in those without extensive ETE; p = 0.017). Additionally, remission was observed only in patients without extensive ETE (10-year cumulative incidence of remission: 0.0% in those with and 29.3% in those without extensive ETE; p = 0.013). CONCLUSIONS: Extensive ETE of the primary lesion results in poorer prognoses for PTC patients with initial distant metastasis. The high CSS rate for patients with stage 4b PTC but no extensive ETE indicates that the prognosis of this patient population should be distinguished from that of other stage 4 cases.

Parathyroidectomy (PTX) is the standard treatment for secondary hyperparathyroidism (SHPT); however, the administration of cinacalcet has gained prominence as a noninvasive treatment. We aimed to determine whether PTX or cinacalcet is more effective in preventing morbidity and mortality through reviewing follow-up data concerning surgical management of SHPT. We retrospectively analyzed and divided 209 patients with SHPT into two treatment groups: PTX (n = 78) and cinacalcet (n = 131) groups. We compared clinical features, the over-the-target range rate during pre- and post-intervention periods, new cardiovascular events, and all-cause mortality between both groups. Almost all biochemical parameters were well controlled in the post-intervention period, and were within the recommended target range for the PTX group but not for the cinacalcet group. A significant difference was observed in the over-the-target range rate during the post-intervention period between the groups. PTX and cinacalcet interventions significantly lowered the over-the-target range rates for serum intact parathyroid hormone (iPTH) (>300 pg/mL), corrected calcium (>10.5 mg/mL), serum phosphorus (>5.5 mg/dL), and calcium-phosphorus product (>55) in both groups (p = 0.001). PTX reduced the risk of new cardiovascular events by 86% compared to cinacalcet (p = 0.001); however, all-cause mortality did not differ significantly (14.1% vs. 7.6%, p = 0.132). For patients with SHPT, PTX helps prevent cardiovascular events through normalizing biochemical variables, according to recommended guidelines. PTX should be considered before cinacalcet treatment to prevent new cardiovascular events. Early PTX for appropriate patients can help prevent immediate postoperative complications and mortality.

BACKGROUND: The posterior retroperitoneoscopic adrenalec tomy has several advantages compared with the transperitoneal approach such as a shorter and more direct route to the target organ, no breach of the intraperitoneal space, and no required retraction of the adjacent organs. It also is a safe procedure with a short learning curve.1-5 This report presents a challenging case of an extra-adrenal paraganglioma located in the aorto-caval space and managed using the retroperitoneal approach. METHODS: A 39-year-old man was placed in the prone jackknife position, and three incisions were made in the right posterior abdominal wall for placement of the laparoscopic ports. The retroperitoneal space was entered with diathermy and blunt finger dissection, and retropneumoperitoneum was achieved with carbon dioxide insufflation pressure up to 18 mmHg. After identification of the right kidney and vessels, the tumor was meticulously dissected and excised with an energy device. The specimen was removed using a laparoscopic specimen retrieval bag, and the port sites were closed in layers. RESULTS: The operative time was 130 min, and the total blood loss was 30 ml. The tumor was diagnosed as a moderately differentiated extra-adrenal paraganglioma. The Von Hippel-Lindau gene mutation was detected using next-generation sequencing. CONCLUSIONS: The posterior retroperitoneoscopic approach is a safe, feasible, and effective method for excising an extra-adrenal paraganglioma even in the aorto-caval space. The authors suggest that this procedure is a useful surgical option for treatment of an aorto-caval paraganglioma for selected patients and by experienced surgeons.

BACKGROUND: Since the use of robot systems in thyroid surgery was introduced in 2007, we have advanced a novel method of robotic thyroidectomy (RT) using a gasless transaxillary approach (TAA). We report our experience with this technique and detail the surgical outcome of 5000 robotic thyroidectomies. METHODS: From October 2007 to May 2016, we successfully performed 5000 robotic thyroidectomies using a gasless TAA at the Department of Surgery, Yonsei University Health System. The medical records of the patients are reviewed retrospectively, and the details of clinicopathologic characteristics, operation times, perioperative complications, and oncologic outcomes are analyzed. RESULTS: The 5000 patients with thyroid tumor (4804 with cancer and 196 with benign tumor) underwent RT using a gasless TAA. Mean operation time was 134.5 ± 122.0 min. The most common histologic subtype of thyroid cancer was papillary (98%), and the mean tumor size was 8.0 ± 6.0 mm. Stage I was found in 85.4% patients regarding tumor nodes metastasis staging. The 196 benign tumors consisted of 104 adenomatous hyperplasias (53.0%), 43 follicular adenomas (21.9%), 30 Graves' diseases (15.3%), and 19 others (9.7%). Postoperative complication occurred in 24.1% without any serious one, and overall morbidity tended to decrease over time. No disease-specific mortality was observed during the follow-up period. Locoregional recurrence was developed in 26 patients (0.5%). CONCLUSION: The authors have tried to improve RT technique using gasless TAA and achieved acceptable surgical outcomes. The rapid evolution of surgical robot technology and our constant effort to advance RT technique using gasless TAA would make it possible to reduce the perioperative morbidity and gain the best possible operative and oncologic outcomes.

BACKGROUND AND OBJECTIVE: Polynucleotide (PN) provides a structural scaffold to induce anti-inflammatory and enhanced wound healing properties, and this study aimed to assess the efficacy of PN administration in the prevention of post-operative scars after conventional open total thyroidectomy. STUDY DESIGN MATERIALS AND METHODS: Forty-two patients with thyroid carcinoma who underwent total thyroidectomy were randomly assigned to the study (PN administration) or control (normal saline) group. All patients underwent a single session of combined ablative and non-ablative fractional laser. The Vancouver Scar Scale (VSS), global photographic assessment, and objective scar were assessed using three-dimensional (3D) camera at baseline and at 2, 4, 8, and 16 weeks after surgery. RESULTS: Patients who underwent PN injection demonstrated better surgical scar quality outcome. Participants in the PN administration group had lower VSS scores than the control group (2.09 ± 0.47 vs. 4.01 ± 0.55, respectively) and lower scar height (0.23 ± 0.03 vs. 0.29 ± 0.03, respectively), as measured using 3D imaging. Furthermore, in the PN injected group, the degree of erythema, and pigmentation of the scar were less prominent. No patient developed hypertrophic scar or keloids on the surgical site. No other adverse events, including post-inflammatory hyperpigmentation, scarring, or infection, were observed. CONCLUSION: Adjuvant administration of PN along with conventional fractional laser treatment led to more favorable effect in wound healing and post-operative scar prevention after thyroidectomy.

RESUMO
BACKGROUND: Robotic modified radical neck dissection (MRND) using a gasless transaxillary approach has been reported to be a safe and meticulous technique in patients with papillary thyroid carcinoma (PTC) and lateral neck node metastasis (N1b). Few studies, however, have attempted to assess the long-term oncologic outcomes of robotic MRND in these patients. This study aimed to compare perioperative and 5-year oncologic outcomes of robotic MRND with conventional open procedures in patients with N1b PTC. METHODS: Between September 2007 and February 2010, 193 patients with N1b PTC underwent total thyroidectomy and MRND by a single surgeon. Of these, 42 (21.8 %) underwent robotic procedures and 151 (78.2 %) underwent conventional open procedures. All patients received 3.7- to 5.5-GBq radioactive iodine (RAI) ablation, post-therapy whole-body scans (TxWBSs), and diagnostic WBS (DxWBSs) during follow-up. An exact 1:3 matching for age and stage was performed to minimize selection bias, and perioperative and 5-year oncologic outcomes were compared in the matched groups. RESULTS: The mean follow-up period was 66.0 months (range 60-90 months). Number of retrieved cervical lymph nodes (LNs) (p = .102) and postoperative ablation success rates (p = .864) were similar between the two groups. TSH-suppressed serum Tg concentrations after 5 years (0.7 ± 1.5 vs. 2.4 ± 14.1 ng/ml; p = .471) and recurrence rates in the robotic and open groups (1/41 [2.4 %] vs. 3/102 [2.9 %]; p = .864) were similar for the 5-year follow-up period. Four patients experienced recurrence: Three exhibited regional lymph node metastasis, and one showed bilateral lung metastases. CONCLUSION: The perioperative and 5-year oncologic outcomes were similar after robotic and conventional open MRND. Large, prospective randomized controlled trials with long-term follow-up data are needed to validate these results.

BACKGROUND: The effect of the systemic lidocaine on postoperative recovery has not been definitively investigated despite its analgesic efficacy after surgery. The aim of this randomized, double-blinded, controlled study was to evaluate the effect of intravenously administered lidocaine on the quality of recovery and on acute and chronic postoperative pain after robot-assisted thyroidectomy. METHODS: Ninety patients who were undergoing robotic thyroidectomy were randomly assigned to the lidocaine or the control groups. The patients received 2 mg/kg of lidocaine followed by continuous infusions of 3 mg/kg/h of lidocaine (Group L) or the same volume of 0.9% normal saline (Group C) intravenously during anesthesia. The acute pain profiles and the quality of recovery, which was assessed using the quality of recovery-40 questionnaire (QoR-40), were evaluated for 2 days postoperatively. Chronic postsurgical pain (CPSP) and sensory disturbances at the surgical sites were evaluated 3 months after surgery. RESULTS: The QoR-40 and pain scores that were assessed during the 2 days that followed surgery were largely comparable between the groups. However, CPSP was more prevalent in the Group C than in the Group L (16/43 vs. 6/41; p = 0.025). The tactile sensory score 3 months after the operation was significantly greater in the Group L than in the Group C (7 vs. 5; p = 0.001). CONCLUSION: Systemic lidocaine administration was associated with reductions in CPSP and sensory impairment after robot-assisted thyroidectomy although it was not able to reduce acute postsurgical pain or improve the quality of recovery. Trial registry number NCT01907997 ( http://clinicaltrials.gov ).

OBJECTIVE: In the current study, we examined whether selenium supplementation during iodine-131 (131I) treatment had a radio-protective effect on salivary glands. SUBJECTS AND METHODS: Sixteen patients with differentiated thyroid cancer were prospectively enrolled in the study. Patients after total thyroidectomy, before 131I treatment, were divided into two groups; 8 patients in the selenium group and 8 patients in the control group. Patients in the selenium group received 300νg of selenium orally for 10 days, from 3 days before to 6 days after 131I treatment. The control group received a placebo over the same period. To assess salivary gland function, salivary gland scintigraphy was performed before and 6 months after 131I treatment. Serum amylase and whole blood selenium levels were measured before and 2 days and 6 months after 131I treatment. Using salivary gland scintigraphy, maximum uptake ratio (MUR), maximum secretion percentage (MSP), and ejection fraction (EF) of each salivary gland were calculated. RESULTS: Baseline clinical characteristics, baseline amylase and selenium levels, and parameters of baseline salivary gland scintigraphy were not significantly different between selenium and control groups (P>0.05). On a blood test performed 2 days after 131I treatment, the selenium group showed a significantly higher whole blood selenium level (P=0.008) and significantly lower serum amylase level (P=0.009) than the control group. On follow-up salivary gland scintigraphy, the control group showed significantly decreased, MUR of the bilateral parotid and left submandibular glands, MSP of the bilateral parotid and submandibular glands, and EF of the left submandibular glands (P<0.05), while the selenium group only had a significant decrease in MSP of the right submandibular gland and EF of the left submandibular gland (P<0.05). CONCLUSION: Selenium supplementation during 131I treatment was effective to reduce salivary glands damage by 131I radiation in patients with differentiated thyroid cancer.

CONTEXT: The increase in thyroid screening in the general population may lead to earlier detection of medullary thyroid carcinoma (MTC). OBJECTIVE: We aimed to evaluate secular trends in clinicopathological characteristics and long-term prognosis of MTC and its prognostic factors. DESIGN: This was a retrospective analysis from 1982 to 2012. PATIENTS: Three hundred and thirty-one patients with MTC were included and grouped based on the year of diagnosis (1982-2000, 2001-2005, 2006-2010 and 2011-2012). MEASUREMENTS: These included recurrence and mortality as well as biochemical remission (BCR) of serum calcitonin. RESULTS: Mean tumour size (from 2·5 cm to 1·7 cm, P < 0·001) and percentage of extrathyroidal extension (from 52·0% to 26·0%, P = 0·026) decreased. The percentage of patients achieving BCR within six postoperative months (po-BCR) increased with time (from 39·6% to 76·1%, P < 0·001). The 5-year overall recurrence rate significantly decreased in 2006-2012 compared to 1982-2005 (10% vs 18%, respectively, P = 0·031), although the 5-year survival rate did not improve (92% vs 92%, P = 0·929). Failure to achieve po-BCR was the strongest predictive factor associated with recurrence (hazard ratio [HR] = 58·04, 95% CI 7·14-472·11; P < 0·001). Male gender (HR = 3·18, 95% CI 1·18-8·56; P = 0·022), tumour size >2 cm (HR = 18·33, 95% CI 2·35-143·06; P = 0·006) and distant metastasis (HR = 4·00, 95% CI 1·31-12·21; P = 0·015) were significant prognostic factors for mortality. CONCLUSIONS: Clinicopathological characteristics and recurrence of MTC improved with time. Po-BCR was the best predictive factor for recurrence-free survival.
