RESUMEN
BACKGROUND: Extrathyroidal extension (ETE) is considered a major prognostic factor in papillary thyroid carcinoma (PTC). Patients with gross ETE are at increased risk of recurrence and mortality. The importance of minimal ETE still remains controversial, especially in patients with papillary thyroid microcarcinoma (PTMC). The purpose of this study was to evaluate the association between ETE and lymph node (LN) metastasis in single PTMC. METHODS: A retrospective analysis was performed of 1994 patients underwent thyroidectomy for PTC between 2012 and 2016 in a single institution. Patients with combined thyroid carcinoma of other types and those who underwent completion thyroidectomy were excluded. After further exclusion of PTC larger than 1 cm and multifocal tumors, 814 patients with single PTMC were included in the study. RESULTS: 72.9% patients had no ETE, 25.1% minimal ETE, and 2.1% gross ETE. ETE was associated with lymphatic invasion, perineural invasion, and vascular invasion. Patients with minimal and gross ETE were also more likely to have LN metastasis, including lateral neck metastasis, compared to those without ETE. In univariate analysis, LN metastasis was associated with male gender, conventional PTC, lymphatic invasion, perineural invasion, and ETE. In multivariate analysis, male gender (OR = 1.987; 95% CI 1.369-2.884), lymphatic invasion (OR = 4.389; 95% CI 1.522-12.658), perineural invasion (OR = 6.545; 95% CI 1.262-33.948), and minimal ETE (OR = 1.852; 95% CI 1.298-2.643) were found to be independent risk factors of LN metastasis. CONCLUSIONS: Minimal ETE is associated with LN metastasis in single PTMC, compared to no ETE. Minimal ETE should be considered in the management of patients with single PTMC, whether surgical or during active surveillance.

BACKGROUND: The prognostic impact of extrathyroidal extensions (ETE) on clinical outcomes has not been well studied in pediatric thyroid cancers. The aim of this study was to analyze the clinicopathological characteristics and clinical outcomes according to the extent of ETE in pediatric and adolescent thyroid cancers. METHODS: This study retrospectively reviewed 89 papillary thyroid carcinoma (PTC) patients less than 19 years of age who underwent total thyroidectomy with central neck dissections (CND) between 1997 and 2018. We compared the clinicopathological features among three groups: no ETE, microscopic ETE, and gross ETE. RESULTS: The median follow-up time was 111 months. The mean age was 15.3 years and the mean tumor size was 2.4 cm. Tumor sizes larger than 2 cm (OR = 9.2, p = 0.001), exhibited bilaterality (OR = 4.3, p = 0.006), were an aggressive variant (OR = 5.8, p = 0.006), and exhibited central lymph node metastasis (OR = 1.3, p = 0.018), lateral lymph node metastasis (OR = 9.2, p = 0.001), recurrence (OR = 3.9, p = 0.038), and distant metastasis (OR = 4.4, p = 0.016) were associated with gross ETE. There was no remarkable difference in clinicopathological characteristics between the no ETE group and microscopic ETE group, except for aggressive variants (OR = 5.5, p = 0.008). There was a significant difference in recurrence-free survival (RFS) rates according to the extent of ETE (p = 0.025). Furthermore, the distant metastasis-free survival curve presented a significant difference among the three groups (p = 0.018). Both microscopic ETE and gross ETE were significantly associated with worse prognoses in pediatric thyroid cancers. CONCLUSIONS: We recommend that microscopic ETE should be included in the intermediate risk category and that gross ETE should be stratified in the high risk group in future revisions of ATA pediatric guidelines.

PURPOSE: The aim of this study was to examine the rate of expression of estrogen receptor α (ERα) and ß1 (ERß1), progesterone receptor (PR), and rate of overexpression of epidermal growth factor receptor (EGFR) in a relatively large cohort of patients with papillary thyroid carcinoma (PTC). We also aimed to examine whether each receptor influenced clinicopathological characteristics and prognosis of PTC. MATERIALS AND METHODS: We made a microarray of paraffin-embedded PTC surgical tissues from 436 patients. We compared the results of the immunohistochemical staining for each hormone receptor with clinicopathological characteristics. RESULTS: The positive expression rate of hormonal receptors was 40.4% for ERα, 83.7% for ERß1, and 71.3% for PR in patients with PTC. Overexpression of EGFR was shown in 19.3% of patients with PTC. The age was lower (44.6±12.1 years vs. 47.1±12.5 years, p=0.040) and tumor smaller (0.96±0.69 cm vs. 1.13±0.82 cm, p=0.020) in the ERα positive group, which also showed higher PR positivity (80.7% vs. 65.0%, p < 0.001) and overexpression of EGFR (27.3% vs. 13.8%, p < 0.001). However, neither the positivity of hormone receptors nor overexpression of EGFR affected the recurrence of PTC. CONCLUSION: In conclusion, most (94.6%) patients with PTC were found to exhibit positive expression for ERs or PR. We also found that neither the positive expression of hormone receptors nor overexpression of EGFR were associated with the recurrence of PTC.

Purpose: Thyroid hormone is an important hormone in maintaining metabolism and homeostasis in the body. There exists a common perception among patients that thyroid surgery will cause weight gain. Prevention of any undesired weight gain could be important for the maintenance of well-being in most patients. Our study compares changes in body mass index (BMI) and weight after total thyroidectomy or lobectomy in thyroid cancer patients. Methods: A total of 967 patients with differentiated thyroid carcinoma were enrolled in the study, from March 2011 to July 2016 at Chung-Ang University Hospital. Exclusion criteria were less than lobectomy, modified radical neck dissection, recurred operation, and combined operation for other causes. Primary endpoints were change in body weight and BMI at 2 years after surgery. A subgroup analysis was performed for patients with significant weight change. Results: There were no differences between both groups in BMI after 2 years of thyroid operation. Thyroid stimulating hormone (TSH) levels were not significantly different. Fifteen percent of patients showed significant change in body weight after 2 years of operation. The subgroup analysis of these patients showed no significant differences in gender, age, or extent of operation between those who had gained weight compared to those who had lost weight. There were also no differences in postoperative TSH levels, levothyroxine supplementation, or radioactive iodine treatment. Conclusion: There was a minimal postoperative increase in mean BMI over the years in patients undergoing thyroidectomy for differentiated thyroid cancer. However, weight change did not differ in those undergoing thyroid lobectomy or total thyroidectomy.
RESUMEN
BACKGROUND: Robotic unilateral modified radical neck dissection (MRND) has been reported to be safe and achieves good oncologic results. However, there is no report of successful robotic bilateral MRND to date. We report the first case series of robotic bilateral MRND through the bilateral axillo-breast approach (BABA). METHODS AND RESULTS: We reviewed 4 patients who presented with papillary thyroid cancer and metastasis to both lateral neck compartments. BABA robotic total thyroidectomy with bilateral MRND was performed. There were no incidences of vocal cord palsy, permanent hypoparathyroidism, or chyle leakage. All patients underwent high-dose radioiodine ablation. At last follow-up, imaging tests showed no recurrence and thyroglobulin levels remained low. CONCLUSIONS: BABA allows complete compartment-oriented neck dissection with outcomes that may be comparable with open bilateral MRND. BABA robotic surgery could be a good alternative for patients with papillary thyroid cancer and bilateral neck metastasis who wish to avoid long neck scar.

OBJECTIVE: The aim of this study was to compare the surgical outcomes of lateral transperitoneal adrenalectomy (LTA) and posterior retroperitoneoscopic adrenalectomy (PRA) for benign adrenal tumor. BACKGROUND: Although LTA is the standard treatment for benign adrenal gland tumor, PRA has recently gained popularity. Studies comparing the surgical outcomes of the 2 approaches have reported conflicting findings and thus it remains unclear which approach is superior. METHODS: This trial was conducted between September 2012 and February 2016. Patients were randomized to either LTA or PRA groups in a 1:1 ratio using web-based randomization. The primary outcome was operative time, and the secondary outcomes were blood loss, intraoperative hemodynamic stability, postoperative pain, recovery of bowel movement, and complication rates. This trial was registered with ClincalTrials.gov, number NCT01676025. RESULTS: A total of 83 patients were randomly assigned to the LTA group (n = 42) or the PRA group (n = 41). Median follow-up was 31.3 months. The mean operative times of LTA and PRA were comparable (59.7â±â18.6 vs 67.6â±â28.7âminutes, P = 0.139). Logistic regression analysis showed that male sex [odds ratio (OR) = 4.20] and pheochromocytoma (OR = 5.06) were associated with an operative time ≥60âminutes. There were no differences in the secondary outcomes between the groups. One patient in the PRA group required open conversion. CONCLUSION: Both LTA and PRA were performed safely with similar operative outcomes, and thus are comparable options for the treatment of benign adrenal gland tumor.

PURPOSE: The purpose of this study was to determine the extent of safety of medial dissection of the thyroid gland along the trachea. Medial to lateral dissection of the thyroid gland along the trachea after early division of the isthmus has been known to be a useful technique in thyroid surgery, especially for difficult cases, but the risk of injury of the recurrent laryngeal nerve (RLN) has constrained thyroid surgeons from utilizing this technique to its full extent. METHODS: Distances of the laryngeal entry point (LEP) of 134 RLNs of 71 patients from the midline of the trachea, and some other anatomical distances, were measured intraoperatively. The relationships of the intraoperatively measured data with circumferences of the cartilaginous portion of the trachea (CCT) around LEP measured preoperatively by CT scan were evaluated. RESULTS: LEP was always located within 2 mm vertically from the horizontally extended line of the inferior border of the cricoid cartilage and was the closest point from the midline in the whole course of the RLN. The distance between LEP and the midline was very closely correlated with CCT measured on preoperative CT scan, and it can be accurately calculated with a regression equation; Distance between LEP and the midline = (0.42 × CCT) + (1.2 × sex) + 3.2 (mm) (sex: female=0, male=1; R2 = 0.85). CONCLUSION: Early division of the isthmus and dissecting the thyroid off the trachea to the calculated extent is a safe and effective procedure.
RESUMEN
BACKGROUND: The association between iodine levels and the risk of papillary thyroid cancer (PTC) has been suggested, but not definitively established. This study is to compare the iodine status of a group of patients with PTC (with and without BRAF V600E) with that of a healthy population cohort. METHODS: A cohort of patients scheduled for thyroidectomy was enrolled, along with a community-based health-screening cohort with no known history of thyroid disease. Median urinary iodine (UI) levels, creatinine-adjusted median UI levels, and food frequency questionnaire (FFQ) scores (mean ± SD) were compared. In a subgroup analysis, these values were compared between BRAF V600E-positive and BRAF V600E-negative patients in the PTC group. RESULTS: The PTC group consisted of 210 patients, and the control group consisted of 90 healthy individuals. Among the 191 PTC patients whose BRAF V600E mutational status was reported, 169 (88.5%) were revealed positive for the mutation. The median UI levels were significantly higher in the PTC group (786.0 µg/l) than the control group (112.0 µg/l; p < 0.001), as was the case with creatinine-adjusted median UI levels (884.6 µg/g creatinine versus 182.0 µg/g creatinine; p < 0.001) and FFQ scores (66.2 ± 17.5, range 13-114 versus 54.6 ± 21.5, range 16-134; p < 0.001). No significant differences were seen in the subgroup analysis between BRAF V600E-positive and BRAF V600E-negative patients. CONCLUSIONS: Our results indicate that iodine status differs significantly between patients with PTC and healthy controls, suggesting that iodine may be involved in the occurrence of PTC, although the association between iodine levels and BRAF mutational status did not reach statistical significance.

BACKGROUND: Clinical trials on bilateral axillo-breast approach (BABA) thyroidectomy show that levobupivacaine and ropivacaine significantly reduce postoperative pain, but they focused on BABA robotic thyroidectomy only and did not identify specific sites of significant pain relief. Our objective was to assess the pain reduction at various sites and safety of ropivacaine-epinephrine flap injection in BABA thyroidectomy. METHODS: This prospective double-blinded randomized controlled trial was conducted in compliance with the revised CONSORT statement (ClinicalTrials.gov registration no. NCT02112370). Patients were randomized into the ropivacaine-epinephrine arm or control (normal saline) arm. RESULTS: From January 2014 to May 2016, 148 patients participated. The primary endpoint was site-specific pain, as measured by numeric rating scale 12âhours after surgery. The ropivacaine-epinephrine group exhibited significantly less swallowing difficulty (Pâ=â.008), anterior neck pain (Pâ=â.016), and right (Pâ=â.019) and left (Pâ=â.035) chest pain. Secondary endpoints were systolic (Pâ=â.402), diastolic (Pâ=â.827) blood pressure, and pulse rate (Pâ=â.397) after injection before incision and during surgery. The vital signs of the groups just after injection did not differ. During surgery, the ropivacaine-epinephrine patients had higher pulse rates (99â±â13.3 vs 88â±â16.1, Pâ<â.001) but within normal range. There were no adverse events such as postoperative nausea and vomiting. There was no significant difference in pain scores in either patient group between patients who underwent robotic or endoscopic interventions. CONCLUSION: BABA flap-site injection with ropivacaine and epinephrine mix before incision effectively and safely reduced postoperative pain. Future studies should focus on tailoring ropivacaine and epinephrine dosage for individuals.

BACKGROUND: Iodine excess has been suggested as an exogenous risk factor of papillary thyroid cancer (PTC). We performed a systematic review and meta-analysis to assess the relationship between iodine exposure measured in various forms and PTC prevalence. METHODS: We searched MEDLINE, Embase, and the Cochrane Library for case-control studies on iodine and PTC published up to December 2015. Exposure to iodine was compared between PTC and control groups. RESULTS: From the 16 selected studies, the odds ratio (OR) for the overall effect size between high iodine exposure and PTC risk was 1.418 (95% confidence interval [CI] 1.054-1.909). Based on 7 studies conducted in high iodinated regions, a positive association between iodine exposure and PTC was observed (OR 2.200; 95% CI 1.389-3.483). CONCLUSION: This study demonstrated a higher exposure to iodine in patients with PTC compared with controls, especially for patients from high iodinated regions.

The purpose of this study was to assess the relationship between vitamin D receptor gene (VDR) expression and prognostic factors in papillary thyroid cancer (PTC). mRNA sequencing and somatic mutation data from The Cancer Genome Atlas (TCGA) were analyzed. VDR mRNA expression was compared to clinicopathologic variables by linear regression. Tree-based classification was applied to find cutoff and patients were split into low and high VDR group. Logistic regression, Kaplan-Meier analysis, differentially expressed gene (DEG) test and pathway analysis were performed to assess the differences between two VDR groups. VDR mRNA expression was elevated in PTC than that in normal thyroid tissue. VDR expressions were high in classic and tall-cell variant PTC and lateral neck node metastasis was present. High VDR group was also associated with classic and tall cell subtype, AJCC stage IV and lower recurrence-free survival. DEG test reveals that 545 genes were upregulated in high VDR group. Thyroid cancer-related pathways were enriched in high VDR group in pathway analyses. VDR mRNA overexpression was correlated with worse prognostic factors such as subtypes of papillary thyroid carcinoma that are known to be worse prognosis, lateral neck node metastasis, advanced stage and recurrence-free survival.
RESUMEN
BACKGROUND: The safety of robotic thyroidectomy (RT) for small-sized thyroid carcinomas has been well established. The surgical outcomes of bilateral axillo-breast approach RT for thyroid carcinomas larger than 2 cm were evaluated and compared with those of open thyroidectomy (OT). METHODS: The medical records of patients who underwent total thyroidectomy or hemithyroidectomy followed by completion thyroidectomy for differentiated thyroid carcinomas measuring 2-4 cm were retrospectively reviewed. RESULTS: The study included 86 patients who underwent RT (n = 21) or OT (n = 65) with mean ages of 30.8 and 51.6 years, respectively. The mean tumor size was 2.8 cm in both groups. There were no significant differences between the RT and OT groups in vocal cord palsy rate (transient, 19.0 vs. 9.2 %; permanent, 0 vs. 1.5 %), postoperative hypoparathyroidism rate (transient, 19.0 vs. 33.8 %; permanent, 4.8 vs. 1.5 %), and the number of retrieved central lymph nodes in papillary thyroid carcinoma patients (6.4 ± 3.5 vs. 6.1 ± 3.9, respectively). The proportion of the patients with serum stimulated thyroglobulin level of <1.0 ng/ml at the initial radioactive iodine treatment was 64.7 % (11/17) for RT group and 66.0 % (35/53) for OT group (p = 0.920). There were three patients (1 RT and 2 OT) who had a biochemical incomplete response, and there was no case of anatomical recurrence or mortality during the median follow-up period of 40.2 months. CONCLUSION: RT is a safe and oncologically sound treatment option for differentiated thyroid carcinomas measuring 2-4 cm in a selected group of patients. The role of RT should be evaluated in correlation with technological advances and increased experience.

BACKGROUND: It is unclear whether near-infrared (NIR) light-induced indocyanine green (ICG) fluorescence can effectively identify, and thus permit the preservation of, parathyroid glands in bilateral axillo-breast approach (BABA) robotic thyroidectomy. This case-control study with a prospectively recruited consecutive series and a retrospectively selected control group assessed the usefulness of ICG with Firefly(R) technology to identify the parathyroid glands intraoperatively during BABA robotic thyroidectomy. METHODS: All consecutive patients (N = 22) who were scheduled to undergo BABA robotic thyroidectomy for papillary thyroid carcinoma in December 2013-August 2015 and met the study eligibility criteria were recruited prospectively. ICG fluorescence was used with the Firefly system (NIR illuminator: 805 nm; filter: 825 nm) integrated in the da Vinci Si robot system to identify the lower parathyroid glands. Parathyroid hormone levels were recorded on postoperative days 0, 1, 2, and 14. Propensity score matching was used to identify an age-, gender-, tumor size-, and operation type-matched group of control patients who underwent BABA robotic thyroidectomy without the Firefly system. The two groups were compared in terms of parathyroid-related outcomes. RESULTS: ICG fluorescence-mediated identification of the parathyroid and thyroid glands required on average (range) 203 ± 89 (125-331) and 207 ± 112 (130-356) s, respectively. The mean (range) fluorescence duration in these glands was 20.8 ± 6.0 (16.6-35.8) and 20.1 ± 7.3 (15.5-33.8) min, respectively. The ICG group had a significantly lower rate of incidental parathyroidectomy than the control group (0 vs. 15.9%, P = 0.048). CONCLUSIONS: ICG with NIR light may feasibly and safely identify the parathyroid glands in BABA robotic thyroidectomy.

PURPOSE: Postoperative pain for robotic thyroid surgeries including bilateral axillo-breast approach (BABA) has not been well studied. In this study, we have developed a self-reporting application (SRA) for iPad and prospectively collected pain scores from open thyroidectomy (OT) and BABA robotic thyroidectomy (RT) patients. METHODS: Female patients who underwent total thyroidectomy for papillary thyroid carcinoma were included. Patients recorded pain scores for throat, anterior neck, posterior neck, chest, and back on postoperative days 1, 2, and 3. Once discharged, on postoperative day 14, a survey was also conducted on satisfaction of SRA and cosmesis. RESULTS: A total of 54 patients were enrolled (27 BABA RT and 27 OT). There were no significant differences between the 2 groups in clinicopathological characteristics and postoperative complication rates. Postoperative pain scores at days 1, 2, 3, and 14 were not significantly different between the groups for throat, anterior neck, posterior neck, or back. Postoperative analgesic requirements were similar between the 2 groups. Wound satisfaction scores were significantly higher in the BABA RT group (BABA RT 7.4 vs. OT 5.7; P = 0.016). Satisfaction scores for the usefulness of SRA were above 7.2 for all four questionnaire items on the 10-point scale. CONCLUSION: Postoperative pain for BABA RT is equivalent to OT but offers greater cosmetic satisfaction for patients. A mobile device application such as SRA may facilitate proper assessment and management of pain in postoperative patients.
RESUMEN
BACKGROUND: There is an ongoing debate about whether robotic thyroidectomy (RT) is appropriate for Graves' disease. The aim of this study was to compare the safety of bilateral axillo-breast approach (BABA) RT with that of open thyroidectomy (OT) in patients with Graves' disease. METHODS: From January 2008 to June 2014, 189 (44 BABA RT and 145 OT) patients underwent total thyroidectomy for Graves' disease. Recurrence of Graves' disease, intraoperative blood loss, hospital stay, and complication rates including recurrent laryngeal nerve (RLN) palsy and hypoparathyroidism were analyzed between BABA RT and OT groups, after propensity score matching according to age, gender, body mass index, surgical indication, the extent of operation, excised thyroid weight, and follow-up period. RESULTS: No patient experienced recurrence of Graves' disease after median follow-up of 35.0 months. Intraoperative blood loss (151.8 ± 165.4 mL vs. 134.5 ± 75.4 mL; p = 0.534) and hospital stay (3.4 ± 0.7 day vs. 3.3 ± 0.7 day; p = 0.564) were not different between BABA RT and OT groups. Complication rates including transient RLN palsy (11.4 vs. 11.4%; p = 1.000), transient hypoparathyroidism (18.2 vs. 20.5%; p = 0.787), permanent RLN palsy (0 vs. 2.3%; p = 0.315), and permanent hypoparathyroidism (2.3 vs. 2.3%; p = 1.000) were also comparable between groups. CONCLUSIONS: BABA RT for Graves' disease showed comparable surgical completeness and complications to conventional OT. BABA RT can be recommended as an alternative surgical option for patients with Graves' disease who are concerned about cosmesis.

BACKGROUND: Laryngeal ultrasonography (LUS) is a new method of vocal cord (VC) evaluation in patients with risk of vocal cord palsy (VCP). The previously described anterior-approach LUS reportedly, however, has high failure rate of VC visualization in male patients. We devised a novel lateral-approach LUS to overcome this limitation. METHODS: A total of 382 (82 male, 300 female) consecutive LUS and direct laryngoscopy (DL) examinations were performed on perioperative thyroidectomy and parathyroidectomy patients. The anterior-approach LUS was used for female patients whereas the lateral-approach LUS was used for male patients. Findings were cross-validated independently with DL examinations. RESULTS: Both anterior and lateral LUS methods had 100% visualization rate (no failed visualization) with an overall sensitivity of 100% (23/23) and specificity of 99.2% (356/359) for VCP. Among the 300 female patients, 18 patients had VCP. Sensitivity and specificity of anterior-approach LUS were 100% (18/18) and 99.3% (280/282), respectively. Among the 80 male patients, 5 patients had VCP. Sensitivity and specificity of lateral-approach LU were 100% (5/5) and 98.7% (76/77), respectively. CONCLUSION: The new LUS approach significantly enhances the visualization of vocal cords and, therefore, overall diagnostic efficacy of LUS in male patients.

PURPOSE: Management of appendicitis in children has always been an issue in pediatric surgery. Both diagnostic methods and treatment vary significantly among medical centers, and little consensus exists in many aspects of the care for patients with appendicitis. Here, we assessed the value of drain insertion after appendectomy in children. METHODS: This study is a retrospective review of pediatric patients who underwent appendectomy for perforated appendicitis at a tertiary medical center between 2003 and 2012. Patients who had a peritoneal drain inserted after appendectomy were compared with patients without drains regarding preoperative features and postoperative outcomes. Statistical analyses included a 2-tailed Student t-test and a chi-square or Fisher exact test. RESULTS: In total, 958 patients were reviewed. Of 342 patients with perforated appendicitis, 108 (31.6%) had Jackson-Pratt (JP) drains inserted. The JP group had a longer hospital stay compared with the non-JP group (6.38 ± 3.59 days vs. 3.87 ± 2.38 days, P < 0.001). The JP group also had higher complication rates (22.2% vs. 6.8%, P = 0.003), including the formation of intra-abdominal abscesses. CONCLUSION: According to our results, there seems to be little evidence to support peritoneal drain insertion after appendectomy, even in perforated appendicitis cases.
