ABSTRACT
Purpose@#Current clinical practices favor less or no thyroid-stimulating hormone (TSH) suppression for low- to intermediate-risk thyroid cancer patients who receive thyroid lobectomy. The association of TSH suppression on healthrelated quality of life (HR-QoL) in patients after thyroid lobectomy is not well studied. This study aimed to evaluate the effect of TSH suppression on patient HR-QoL after thyroid lobectomy. @*Methods@#This study included patients enrolled in an ongoing, multicenter, randomized controlled study investigating the effects of TSH suppression. Patients were randomized to either the low-TSH group (TSH target range, 0.3–1.99 μIU/ mL) or the high-TSH group (TSH target range, 2.0–7.99 μIU/mL). The HR-QoL, hyperthyroidism symptom, and depression symptom questionnaires performed preoperatively and 2 weeks and 3 months postoperatively were evaluated. @*Results@#Total of 669 patients (low-TSH group, 340; high-TSH group, 329) were included. Although total HR-QoL score changes were not different between the 2 groups, the high-TSH group had a significantly higher score in the physical domain at postoperative 3 months (P = 0.046). The 2 groups did not have significant differences in hyperthyroidism and depression scores. @*Conclusion@#In the short-term postoperative period, the physical HR-QoL scores in thyroid lobectomy patients were better when they did not receive TSH suppression. This study suggests the importance of considering HR-QoL when setting TSH suppression targets in thyroid lobectomy patients.
ABSTRACT
PURPOSE@#Proximal gastrectomy (PG) is a function-preserving surgery in cases of proximally located early-stage gastric cancer. Because gastroesophageal reflux is a major pitfall of this operation, we devised a modified esophagogastrostomy (EG) anastomosis to fix the distal part of the posterior esophageal wall to the proximal part of the anterior stomach wall to produce an anti-reflux mechanism; we named this the SPADE operation. This study aimed to show demonstrate the clinical outcomes of the SPADE operation and compare them to those of previous PG cases.@*MATERIALS AND METHODS@#Case details of 56 patients who underwent PG between January 2012 and March 2018 were retrospectively reviewed: 30 underwent conventional esophagogastrostomy (CEG) anastomosis using a circular stapler, while 26 underwent the SPADE operation. Early postoperative clinical outcome-related reflux symptoms, endoscopic findings, and postoperative complications were compared in this case–control study.@*RESULTS@#Follow-up endoscopy showed more frequent reflux esophagitis cases in the CEG group than in the SPADE group (30% vs. 15.3%, P=0.19). Similarly, bile reflux (26.7% vs. 7.7%, P=0.08) and residual food (P=0.01) cases occurred more frequently in the CEG group than in the SPADE group. In the CEG group, 13 patients (43.3%) had mild reflux symptoms, while 3 patients (10%) had severe reflux symptoms. In the SPADE group, 3 patients (11.5%) had mild reflux symptoms, while 1 had severe reflux symptoms (absolute difference, 31.8%; 95% confidence interval, 1.11–29.64; P=0.01).@*CONCLUSIONS@#A novel modified EG, the SPADE operation, has the potential to decrease gastroesophageal reflux following a PG.
ABSTRACT
Purpose@#We devised omental free-shaped flap reinforcement on anastomosis and dissected area (OFFROAD) following reconstruction after gastrectomy. This study aimed to evaluate its safety and early clinical outcomes. @*Methods@#One hundred fifty-six patients who underwent totally laparoscopic distal gastrectomy with delta anastomosis from July 2016 to April 2018 were divided into the OFFROAD group (80 patients) and non-OFFROAD group (76 patients). Differences in short-term operative outcomes and surgical complications were compared between the groups. All patients’ inflammatory marker levels were measured to monitor flap necrotic change and inflammatory reactions. The clinical features of both groups in terms of anastomotic leakage were transcribed. @*Results@#Pain score in postoperative day1 was significantly lower in OFFROAD group. The serum WBC count on POD 1 was significantly lower in OG than in NOG. The mean duration of OFFROAD was shorter than five minutes. There were no statistical differences in short-term outcomes and surgical complications between two groups. Anastomotic leakage occurred in three patients in each group and there was no statistical difference in incidence. However, clinical features were notable when anastomotic leakage occurs. Unlike all three patients of non-OFFROAD group manifested every features of peritonitis, each patient of OFFROAD group just manifested only one of the three. @*Conclusion@#This study showed the safety and feasibility of OFFROAD procedure. It might mitigate septic complications when there is an anastomotic leakage. Additional large-scale study is needed to assess the versatile usefulness of OFFROAD aside from its role as a physical barrier.

ABSTRACT
PURPOSE: The purpose of this study was to develop a Korean version of the self-reported thyroid-specific quality of life (QoL) questionnaire for thyroid cancer patients (KT-QoL), and to evaluate its reliability and validity. MATERIALS AND METHODS: Two hundred seventy-two patients who underwent thyroidectomy from January to December 2010 were recruited in this study. The original version of the thyroid QoL was translated into Korean and evaluated for its reliability and validity. Using the developed KT-QoL, the postoperative QoL was evaluated until postoperative 1 year. RESULTS: At the preoperative baseline, the item internal consistency (IIC) ranged from −0.19 to 0.76, with low IIC values for items 2, 17, and 27. Item discriminant validity ranged from 86% to 97%. These values were similar at the postoperative periods. The internal consistency reliability (Cronbach's α) was high for all dimensions, ranging from 0.90 to 0.95. The test-retest reliability (intraclass correlation coefficient) was acceptable (0.74-0.82). The external validity examined by the correlation between the item 1j (voice changes) of KT-QoL and the voice handicap index-30 ranged from 0.51 to 0.75. Patients' QoL scores decreased after surgery, which demonstrated the sensitivity of the questionnaire. The QoL scores in patients with lobectomy showed best QoL scores postoperatively and those with receiving radioactive iodine still showed decreased QoL scores along the postoperative periods. CONCLUSION: These results demonstrate that KT-QoL is a valid instrument for evaluating QoL of Korean patients with thyroid cancer.

Moonlighting proteins exhibit multiple activities in different cellular compartments, and their abnormal regulation could play an important role in many diseases. To date, many proteins have been identified with moonlighting activity, and more such proteins are being gradually identified. Among the proteins that possess moonlighting activity, several secreted proteins exhibit multiple activities in different cellular locations, such as the extracellular matrix, nucleus, and cytoplasm. While acute inflammation starts rapidly and generally disappears in a few days, chronic inflammation can last for months or years. This is generally because of the failure to eliminate the cause of inflammation, along with repeated exposure to the inflammatory agent. Chronic inflammation is now considered as an overwhelming burden to the general wellbeing of patients and noted as an underlying cause of several diseases. Moonlighting proteins can contribute to the process of chronic inflammation; therefore, it is imperative to overview some proteins that exhibit multiple functions in inflammatory diseases. In this review, we will focus on inflammation, particularly unravelling several well-known secreted proteins with multiple functions in different cellular locations.

BACKGROUND: The ongoing Multicenter Prospective Cohort Study of Active Surveillance on Papillary Thyroid Microcarcinoma (MAeSTro) aims to observe the natural course of papillary thyroid microcarcinoma (PTMC), develop a protocol for active surveillance (AS), and compare the long-term prognosis, quality of life, and medical costs between the AS and immediate surgery groups. METHODS: This multicenter prospective cohort study of PTMC started in June 2016. The inclusion criteria were suspicious of malignancy or malignancy based on fine needle aspiration or core needle biopsy, age of ≥18 years, and a maximum diameter of ≤1 cm. If there was no major organ involvement, no lymph node/distant metastasis, and no variants with poor prognosis, the patients were explained of the pros and cons of immediate surgery and AS before selecting AS or immediate surgery. Follow-up visits (physical examination, ultrasonography, thyroid function, and questionnaires) are scheduled every 6 months during the first 2 years, and then every 1 year thereafter. Progression was defined as a maximum diameter increase of ≥3, ≥2 mm in two dimensions, suspected organ involvement, or lymph node/distant metastasis. RESULTS: Among 439 enrolled patients, 290 patients (66.1%) chose AS and 149 patients (33.9%) chose immediate surgery. The median follow-up was 6.7 months (range, 0.2 to 11.9). The immediate surgery group had a larger maximum tumor diameter, compared to the AS group (7.1±1.9 mm vs. 6.6±2.0 mm, respectively; P=0.014). CONCLUSION: The results will be useful for developing an appropriate PTMC treatment policy based on its natural course and risk factors for progression.

Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to develop clinical practice guidelines for the surgical treatment of laryngeal cancer. This Task Force conducted a systematic search of the EMBASE, MEDLINE, Cochrane Library, and KoreaMed databases to identify relevant articles, using search terms selected according to the key questions. Evidence-based recommendations were then created on the basis of these articles. An external expert review and Delphi questionnaire were applied to reach consensus regarding the recommendations. The resulting guidelines focus on the surgical treatment of laryngeal cancer with the assumption that surgery is the selected treatment modality after a multidisciplinary discussion in any context. These guidelines do not, therefore, address non-surgical treatment such as radiation therapy or chemotherapy. The committee developed 62 evidence-based recommendations in 32 categories intended to assist clinicians during management of patients with laryngeal cancer and patients with laryngeal cancer, and counselors and health policy-makers.

OBJECTIVES: Advancements in medical endoscopy and techniques of rigid bronchoscopy for foreign body removal have enabled higher diagnostic accuracy, reduced morbidity and precise manipulation. However, in pediatric patients, endoscope-combined forceps may be too big to fit into the small sized airway. Here we present our method of endoscope assisted rigid bronchoscopy in pediatric patients and compare the clinical benefits with conventional naked-eye rigid bronchoscopy. METHODS: We used a 2.7 mm, 0degrees straight endoscope and small caliber grasping forceps with 3.0 to 4.5 mm sized rigid bronchoscopy for very young (<3 years of age) patients of foreign body aspiration. As an assistant held the rigid bronchoscope in situ, the operator could manipulate the endoscope and forceps bimanually. With endoscopic guidance, the foreign body retrieval was performed carefully. The clinical advantages were compared between our endoscope-assisted method (n=29) and the conventional bronchoscopy method (n=33) in terms of operation time and recovery (hospital stay). RESULTS: Bimanual endoscope-assisted rigid bronchoscopy method was technically feasible and safe. The operation time was less, compared to the conventional technique and the patients recovered more quickly. In all cases, our method completely removed the foreign body without need of a second bronchoscopy procedure. CONCLUSION: Bimanual endoscope-assisted retrieval of airway foreign body in very young age pediatric patients was superior to the conventional naked-eye method concerning accurate manipulation and safety.

Low grade nasopharyngeal papillary adenocarcinoma (LGNPPA) is an extremely rare variant of nasopharyngeal cancer, which exhibits distinct clinicopathological characteristics. Surgical resection has been regarded as the principal treatment. For this, transpalatal or transfacial approach has been classically used for exposure of the field. Up for now, there has been no report on applying endoscopic approach for this disease, which could be an effective alternative to minimize possible morbidities of palatotomy or maxillotomy. Endoscopic approach can be justified considering narrow extent and indolent behavior of LGNPPA. We report a patient with LGNPPA, which was successfully resected exclusively by endoscopic visualization. Our case exhibited narrow-based exophytic features with compatible immunopathologic profiles of LGNPPA. Exclusive endoscopic resection can be effective and less-morbid modality for this rare disease as in this case.

Unlike most thyroid cancers which have an excellent prognosis with standard treatments such as surgery and additional radioactive iodine therapy followed by long term TSH suppression, 15-20% of differentiated thyroid cancers are unresponsive, showing locally aggressive behavior or distant metastasis. It has been reported that the ability of iodine uptake among residual follicular cells is usually impaired in such unresponsive cases. As the general incidence of thyroid cancer increases, the number of this radioactive iodine refractory disease is also increasing. This becomes clinically challenging because iodine-based diagnostic and therapeutic approaches are not applicable anymore. Moreover, other conventional modalities including radiotherapy or cytotoxic chemotherapy is neither effective in this subset of thyroid cancer. So many researches are currently under way to find effective molecular targeted therapies, which will play a role in the treatment of these unresectable and advanced cases. This review discusses the recent research progress regarding the iodine avidity of follicular cells in thyroid cancer, and outcomes of clinical studies using targeted agents.
