Sodium-iodide symporter and its related solute carriers in thyroid cancer.

The solute carrier (SLC) family is a large group of membrane transport proteins. Their dysfunction plays an important role in the pathogenesis of thyroid cancer. The most well-known SLC is the sodium-iodide symporter (NIS), also known as sodium/iodide co-transporter or solute carrier family 5 member 5 (SLC5A5) in thyroid cancer. The dysregulation of NIS in thyroid cancer is well documented. The role of NIS in the uptake of iodide is critical in the treatment of thyroid cancer, radioactive iodide (RAI) therapy in particular. In addition to NIS, other SLC members may affect the autophagy, proliferation, and apoptosis of thyroid cancer cells, indicating that an alteration in SLC members may affect different cellular events in the evolution of thyroid cancer. The expression of the SLC members may impact the uptake of chemicals by the thyroid, suggesting that targeting SLC members may be a promising therapeutic strategy in thyroid cancer.

The prevalence of gastroesophageal reflux disease and laryngopharyngeal reflux in patients with dysphagia after radiotherapy for nasopharyngeal carcinoma.

BACKGROUND: The prevalence of gastroesophageal reflux disease (GERD) and laryngopharyngeal reflux (LPR) in post-irradiated patients with nasopharyngeal carcinoma (NPC) is unknown. MATERIALS AND METHODS: In a cross-sectional study, 31 NPC and 12 control patients completed questionnaires for GERD/LPR before esophageal manometry and 24-h pH monitoring. The DeMeester score and reflux finding score (RFS) were used to define GERD and LPR, respectively. Risk factors were identified. RESULTS: 51.6% of NPC and 8.3% of control patients, and 77.4% of NPC and 33% of control patients, were GERD-positive and LPR-positive, respectively. The GERD/LPR questionnaire failed to identify either condition in patients with NPC. No parameter differences in esophageal manometry or pneumonia incidence were noted between GERD/LPR-positive and GERD/LPR-negative patients. Post radiotherapy duration, high BMI, lack of chemotherapy, and dysphagia were positive risk factors for GERD/LPR. CONCLUSIONS: A high prevalence of GERD/LPR in patients with post-irradiated NPC exists, but reflux symptoms are inadequate for diagnosis.

A Hybrid Auricular Framework of Autologous Rib Cartilage and a Porous Polyethylene Implant for Reconstruction of Congenital Microtia: A Modification of Nagata's Technique.

Background: An implant (porous polyethylene) is an alternative to rib cartilage for microtia reconstruction but carries a risk of extrusion. Objective: To evaluate the outcome of a hybrid framework of implant with rib cartilage for microtia reconstruction. Methods: Patients who underwent Nagata's technique for microtia reconstruction were reviewed for complications and aesthetic score. In stage 1, a rib cartilage framework or a hybrid framework of implant with rib cartilage was used. In stage 2, the framework was elevated and supported by an implant for projection. Postoperative outcomes were reported for both groups. Results: Forty-four ears of 40 patients underwent surgery. Eleven ears received a rib auricular framework and 33 ears a hybrid auricular framework. The mean postoperative follow-up for the rib and hybrid groups was 76.3 and 43.1 months, respectively. No supporting postauricular implant extruded, whereas stainless-steel wires extruded in seven ears (15.9%). Five (15.2%) hybrid frameworks were removed due to infection or extrusion. Mean operating time was 2 h shorter in the hybrid group. Aesthetic outcomes were similar for both groups. Conclusion: A hybrid framework of rib and implant that requires less harvested cartilage is feasible for microtia reconstruction, but caution should be used due to its higher explantation rate.

Clinical performance, safety, and patient-reported outcomes of an active osseointegrated bone-conduction hearing implant system at 24-month follow-up.

PURPOSE: To investigate 2-year post-operative hearing performance, safety, and patient-reported outcomes of hearing-impaired adults treated with the Osia® 2 System, an active osseointegrated bone-conduction hearing implant that uses piezoelectric technology. METHODS: A prospective, multicenter, open-label, single-arm, within-subject clinical study conducted at three tertiary referral clinical centers located in Melbourne, Sydney and Hong Kong. Twenty adult recipients of the Osia 2 System were enrolled and followed up between 12 and 24 months post-implantation: 17 with mixed or conductive hearing loss and 3 with single-sided sensorineural deafness. Safety data, audiological thresholds, speech recognition thresholds in noise, and patient-reported outcomes were collected and evaluated. In addition, pre-and 6-month post-implantation data were collected retrospectively for this recipient cohort enrolled into the earlier study (ClinicalTrials.gov NCT04041700). RESULTS: Between 6- and 24-month follow-up, there was no statistically significant change in free-field hearing thresholds or speech reception thresholds in noise (p = > 0.05), indicating that aided improvements were maintained up to 24 months of follow-up. Furthermore, improvements in health-related quality of life and daily hearing ability, as well as clinical and subjective measures of hearing benefit remained stable over the 24-month period. No serious adverse events were reported during extended follow-up. CONCLUSIONS: These study results provide further evidence to support the longer term clinical safety, hearing performance, and patient-related benefits of the Osia 2 System in patients with either a conductive hearing loss, mixed hearing loss, or single-sided sensorineural deafness. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT04754477. First posted: February 15, 2021.

Quality of life and swallowing outcomes after early proactive swallowing rehabilitation by either transcutaneous neuromuscular electrical stimulation or exercise-based swallowing training in patients with nasopharyngeal carcinoma after radiotherapy.

Background: Exercise-based swallowing training (EBST) and transcutaneous neuromuscular electrical stimulation (TNMES) are common modalities used to treat late dysphagia after radiotherapy for nasopharyngeal carcinoma (NPC). We aimed to investigate and compare the efficacies of EBST and TNMES as proactive treatments administered early after radiotherapy. Methods: Patients with early post-radiotherapy NPC (n = 120) underwent either TNMES or EBST. Flexible endoscopic evaluation of swallowing (FEES), quality of life (QOL), and swallowing function questionnaires were completed before the intervention as well as immediately, 6, and 12 months after the intervention. Outcome measures included the scores for the swallowing function score (SFS), penetration and aspiration scale (PAS), dynamic imaging grade of swallowing toxicity (DIGEST), functional oral intake scale (FOIS), swallowing performance status scale (SPSS), pharyngeal motor impairment (PMI), pharyngeal function impairment (PFI), and functional assessment after cancer therapy-nasopharyngeal (FACT-NP) questionnaire. Results: Three months after radiotherapy, 31 and 34 patients underwent TNMES and EBST, respectively, and completed swallowing assessments at all four assessment timepoints. All patients showed post-radiotherapy impairments in the SFS, PAS, DIGEST, PMI, and PFI. Compared with the EBST group, the TNMES group showed significant improvements in the PFI and PMI scores, with small-to-medium effect sizes. Additionally, compared with the EBST group, the TNMES group demonstrated a trend toward slightly better improvements in the PAS, DIGEST, FOIS, and SPSS scores immediately and 6 months after the intervention. The SFS scores improved from baseline in both groups; however, the TNMES group showed an earlier improvement. Finally, the TNMES group showed better QOL according to the FACT-NP than the EBST group. Conclusion: Proactive TMNES and EBST are safe and feasible modalities for improving swallowing in patients with NPC when administered early after radiotherapy. Although TNMES showed better results than EBST, these results should be interpreted with caution given the study limitations. Level of evidence: 1B.

Applying computer-based language test to young children.

INTRODUCTION: This study aims at exploring the feasibility of applying a computer-based language test to young children aged 2-4 years. METHODS: Thirty-two Cantonese-speaking children, aged 2-4 years, were recruited from local kindergartens. All participants underwent assessment using both the computer-based and paper-pencil versions of the Macau Cantonese Language Screening Scale for Preschool Children, following a crossover study design. A short break of 15-30 minutes was provided between the two assessments. The data were analysed at three levels: the overall test, subcategory, and individual item levels. At the overall test and subcategory levels, data were analysed using the paired samples t-test and ICC. At the item level, the percentage of agreement and Cohen's kappa value were selected to assess the agreement of the two test formats. RESULTS: Excellent agreement was found for the overall test level, and good agreement was observed for four of the five subcategories. At the individual item level, 28 of the 35 items showed more than 80% agreement, and 16 items showed substantial to almost perfect agreement. CONCLUSION: These results suggest that the two test formats give similar total scores and subcategory scores for children aged 2-4. For children older than 2 years, 6 months, the agreement for matching items is as high as 83.68% (1318/1575). The computer-based test is thus highly recommended for this group of children. For children younger than 2 years, 6 months, a modified computer-based test is suggested to accommodate their needs.

Effects of Patient-Reported Outcome Tracking and Health Information Provision via Remote Patient Monitoring Software on Patient Outcomes in Oncology Care: A Systematic Review and Meta-Analysis.

OBJECTIVES: The authors sought to 1) review the literature on the remote care model that uses remote patient monitoring software (RPMS) as key mechanisms in oncology care for symptom tracking and health information provision and (2) compare the remote care model to standard care in terms of health-related quality of life, symptom burden, health management self-efficacy, anxiety, and depression. DATA SOURCES: The search was conducted on March 23, 2022, in the Cochrane Library, MEDLINE/PubMed, PsycINFO, and CINAHL databases. RESULTS: The primary strategies for applying digital technology in remote care models are patient-reported outcomes (PRO) tracking and health information delivery. Common PRO measurements applied in the RPMS include quality of life, symptom burden, self-efficacy, anxiety, and depression. Nine randomized controlled trials testing seven RPMS interventions were examined. Compared to standard care, remote patient monitoring via RPMS was related to greater quality of life and lower physical symptom burden during cancer therapy. The RPMS incorporated into routine clinical care with nurses providing remote monitoring performed better on PRO than that not integrated. CONCLUSION: The RPMS-based remote care model improves patient outcomes during cancer treatment, and it is not inferior to standard care until the RPMS function is more integrated with existing clinical care. IMPLICATIONS FOR NURSING PRACTICE: Nurses are well-positioned to engage patients in self-care skills via RPMS and can play a vital role in integrating such a model of remote patient care into routine care practices.

Feasibility and self-perceived effectiveness of an online training program on dysphagia in residential aged care homes in mainland China.

BACKGROUND: With a rapidly aging population in mainland China, dysphagia has become one of the common geriatric disorders which creates a huge demand on speech and language therapists (SLTs). The major challenge is the shortage of SLTs in China. In addition, frontline practitioners in mainland China may not be well equipped with the knowledge and practical skills in dysphagia management due to lack of systematic training and the work nature. AIMS: This study evaluates the self-perceived effectiveness and feasibility of an online training program that aims to enhance the self-assessed knowledge and skills of SLTs providing dysphagia care in residential aged care homes. METHODS AND PROCEDURES: Sixteen SLTs working in a residential aged care homes in mainland China attended a three-hour pilot online training program which consists of didactic lecture and practical skills activity components. A total of 10 participants completed an online questionnaire one month after the training to evaluate the feasibility and effectiveness of this online training program. OUTCOMES AND RESULTS: The preliminary results demonstrated participants' self-perception of high training effectiveness in theoretical knowledge and practical skills. A majority of the participants perceived that the training enhanced their theoretical knowledge and all of them perceived that they acquired practical skills. All respondents were satisfied with the online training approach. They also highlighted the advantage and challenges of the online training approach. CONCLUSIONS AND IMPLICATIONS: Online training is an effective and feasible approach for theoretical knowledge and practical skills transfer in SLT training and could ultimately benefit the delivery of services for individuals with dysphagia in mainland China. WHAT THIS PAPER ADDS: What is already known on the subject Previous studies have shown that online training approach is as effective as face-to-face training in increasing professional knowledge. Online training programs may be more cost efficient and time efficient when compared with face-to-face training. What this study adds The present study provided preliminary evidence to support the feasibility and effectiveness of using online training on dysphagia for speech and language therapists working in residential aged care homes in mainland China. What are the clinical implications of this work? From the participants' perception, online training approach is effective and feasible in delivering theoretical knowledge and practical skills. It may be a better training approach for mainland China considering the lack of expertise and accessibility to training.

The Extent of Hearing Input Affects the Plasticity of the Auditory Cortex in Children With Hearing Loss: A Preliminary Study.

PURPOSE: This study investigated to what extent residual hearing and rehabilitation options (e.g., hearing aids [HAs]) affect the auditory cortex in children with hearing loss. METHOD: Twenty-one children with bilateral congenital sensorineural hearing loss who were candidates for cochlear implantation were recruited. Voxel-based morphometry analysis was conducted to assess the gray matter (GM) volume in the auditory cortex. Children's residual hearing was measured by pure-tone audiometry at different frequencies. Multiple linear regression models were conducted to examine the effects of residual hearing and the use of HAs on GM volume in the auditory cortex with the control of age and gender. RESULTS: Children with more residual hearing at high frequencies had larger GM volume ratio (corrected by total intracranial volume) in the left Heschl's gyrus (r = -.545, p = .013). An interaction effect between residual hearing and the use of HAs suggested that the effect of residual hearing on GM ratio was moderated by the use of HAs (ß = -.791, p = .020). Compared with children with less residual hearing, children who had more residual hearing benefited more from longer use of HAs in terms of a larger GM ratio. CONCLUSIONS: Our preliminary findings highlight the impact of residual hearing on the neuroanatomy of the auditory cortex in children with hearing loss. Moreover, our results call for more auditory input via HAs for children with more residual hearing to preserve the auditory cortex before cochlear implantation. For children with less residual hearing who might receive limited benefit from HAs, an early cochlear implant would be necessary.

Protection of the marginal mandibular branches of the facial nerves by different surgical procedures in comprehensive cervical lymphadenectomy for locally advanced oral and oropharyngeal cancer: a multicenter experience.

OBJECTIVE: According to the different characteristics of patients and cervical lymph node metastasis of oral and oropharyngeal cancer, the marginal mandibular branches of facial nerves were treated by different surgical procedures, and the safety and protective effects of different surgical procedures were investigated. METHODS: One hundred ninety-seven patients with oral and oropharyngeal cancer satisfying the inclusion criteria were selected. According to the different characteristics of patients and cervical metastatic lymph nodes, three different surgical procedures were used to treat the marginal mandibular branches of the facial nerve: finding and exposing the marginal mandibular branches of the facial nerves at the mandibular angles of the platysma flaps, finding and exposing the marginal mandibular branches of facial nerves at the intersections of the distal ends of facial arteries and veins with the mandible, and not exposing the marginal mandibular branches of the facial nerves. The anatomical position, injury, and complications of the marginal mandibular branches of the facial nerves were observed. RESULTS: The marginal mandibular branches of the facial nerves were found and exposed at the mandibular angles of the platysma flaps in 102 patients; the marginal mandibular branches of facial nerves were found and exposed at the intersections of the distal ends of the facial arteries and veins with the mandibles in 64 patients; the marginal mandibular branches of facial nerves were not exposed in 31 patients; among them, four patients had permanent injury of the marginal mandibular branches of the facial nerves, and temporary injury occurred in seven patients. There were statistically significant differences in the protection of the mandibular marginal branch of the facial nerve among the three different surgical methods (P = 0.0184). The best protective effect was to find and expose the mandibular marginal branch of the facial nerve at the mandibular angle of the platysma muscle flap, and the injury rate was only 2.94%. CONCLUSION: The three different surgical procedures were all safe and effective in treating the marginal mandibular branches of the facial nerves, the best protective effect was to find and expose the mandibular marginal branch of the facial nerve at the mandibular angle of the platysma muscle flap.

Lexical tone perception and production in Cantonese-speaking children with childhood apraxia of speech: a pilot study.

Childhood apraxia of speech (CAS) is a paediatric motor speech disorder. We investigated the lexical tone perception and production abilities of children with CAS and the relationships between the two. Three children with CAS, aged between 3;7 and 5;8, were given the Cantonese Tone Identification Test (CANTIT) and the Hong Kong Cantonese Articulation Test (HKCAT) for assessment of tone perception and production, respectively. Accuracy and error patterns were investigated based on their performance on the two tests. Correlation analysis was performed on children's perception and production scores. Two children scored at the lowest rank on the CANTIT, while one child obtained a Z score of 0. All children scored three standard deviations below the mean on the HKCAT. No statistical differences were found among the six tones with respect to perception accuracy, H(5) = 3.731, p = 0.589. Error analysis showed that children with CAS demonstrated more confusion on perceiving tones compared with TD peers. There were no main effects for task (F(1,2) = 0.040, p = 0.859) or tone (F(5,10 = 0.997, p = 0.467); nor were there task or tone interaction effects on perception versus production accuracy (F(5,10) = 1.772, p = 0.206). Tone perception and production accuracy were not significantly correlated (r2 = 0.181, p = 0.078). Tone perception deficits were evident in two out of three children with CAS, while all children had lexical tone production difficulties. In this small sample, tone production was more universally affected than tone perception.

Treatment intensity components including dose, dose form, session duration, and total intervention duration were documented.

Repair of postoperative defects of oral cancer with submental island flaps based on vascular pedicles of different states: a multicenter retrospective study.

Submental island flap has certain advantages in repairing postoperative defects of oral cancer, and it can often achieve similar or even better effects compared with those of the free tissue flap. In this study, according to the different characteristics of patients and postoperative defects of oral cancer, submental island flaps with different states of vascular pedicle were prepared, and its repair methods, safety, and clinical effects in treating postoperative defects of oral cancer were investigated. 83 patients with oral cancer who met the inclusion criteria were selected. According to the different characteristics of the patients and postoperative defects of oral cancer, the traditional submental island flap vascular pedicle was modified into three different states: submental artery perforator flap, vascular pedicled flap with the anterior belly of digastric muscle but without the submandibular gland (SIF with anterior belly of DM), and vascular pedicled flap with the anterior belly of the digastric muscle and the submandibular gland (SIF with anterior belly of DM and SG). The types of the submental artery and the drainage vein, flap survival, and complications, were observed. The flap was successfully harvested for all patients, and the submental artery could be found or separated for all of them, with the venous drainage to the internal jugular vein in 57 (57/83, 68.67%), to the external jugular vein in 18 (18/83, 21.69%), and to the anterior jugular vein in eight (8/83, 9.64%) cases. Submental artery perforator flap was used for 11 cases, complete necrosis occurred in two cases (2/11, 18.18%), partial necrosis occurred in one case (1/11, 9.09%); SIF with anterior belly of DM was used for 49 cases, complete necrosis occurred in one case (1/49, 2.04%), partial necrosis occurred in four cases (4/49, 8.16%); SIF with anterior belly of DM and SG was used for 23 cases, including chimeric flap combining the submental island flap and the submandibular gland used for 15 cases, there were no cases of complete or partial necrosis. Submental island flap was effective in repairing postoperative defects of oral cancer. Submental island flaps with three different states of vascular pedicle could repair oral cancer-affected tissues with different defect characteristics.

The Isoforms of Estrogen Receptor Alpha and Beta in Thyroid Cancer.

The incidence of thyroid cancer was predominant in women, indicating that the sex hormone may have a role in thyroid cancer development. Generally, the sex hormone exerts its function by binding to the correspondent nuclear receptors. Therefore, aberrant of these receptors may be involved in the development of thyroid cancer. Estrogen receptor alpha (ERα) and beta (ERß), two main estrogen receptors, have been reported to have an important role in the pathogenesis of thyroid cancer. When the ERα and ERß genes undergo the alternative RNA splicing, some ERα and ERß isoforms with incomplete functional domains may be formed. To date, several isoforms of ERα and ERß have been identified. However, their expression and roles in thyroid cancer are far from clear. In this review, we summarized the expressions and roles of ERα and ERß isoforms in thyroid cancer, aiming to provide the perspective of modulating the alternative RNA splicing of ERα and ERß against thyroid cancer.

OBJECTIVE: To investigate the clinical performance, safety, and patient-reported outcomes of an active osseointegrated steady-state implant system that uses piezoelectric technology. STUDY DESIGN: A prospective, multicenter, open-label, single-arm, within-subject clinical investigation. SETTING: Three tertiary referral clinical centers located in Melbourne, Sydney, and Hong Kong. PATIENTS: Twenty-nine adult subjects, 24 with mixed hearing loss or conductive hearing loss and 5 with single-sided sensorineural deafness. INTERVENTION: Implantation with the Cochlear Osia 2 System. MAIN OUTCOME MEASURES: Audiological threshold evaluation and speech recognition in quiet and in noise. Patient satisfaction and safety. RESULTS: At 6-month follow-up after surgery, a mean improvement in pure-tone average of 26.0 dB hearing level and a mean improvement of 8.8 dB signal-to-noise ratio in speech reception threshold in noise was achieved with the investigational device as compared with the unaided situation. Usability of the investigational device was rated 71.4/100 mm for sound processor retention and 81.4/100 mm for overall comfort using a visual analog scale. CONCLUSION: These outcomes confirm the clinical safety, performance, and benefit of an innovative active transcutaneous bone conduction implant using a piezoelectric transducer design in subjects with conductive hearing loss, mixed hearing loss, or single-sided sensorineural deafness.

A Chinese Medicine Formula (Bushen Huoxue Tongluo) for the Treatment of Chronic Subjective Tinnitus: A Study Protocol for a Pilot, Assessor-Blinded, Randomized Clinical Trial.

Background: Tinnitus is a common problem worldwide. There is still no effective method to cure it. Traditional Chinese medicine (TCM) may be a potentially effective treatment approach for tinnitus. However, there is still no clinical trial with scientifically rigorous methodology to evaluate the treatment effect of TCM for tinnitus. Therefore, we propose a pilot study to inform the feasibility of a future full-scale RCT to establish the efficacy of TCM formula for tinnitus. Objectives: The aim of this study is to determine the feasibility of a full-scale RCT and explore whether a TCM formula (BHT) has an additional effect on improving tinnitus when compared to informative counseling alone. Design: An assessor-blinded, randomized, controlled clinical trial is used. Participants: Twenty-four patients with chronic subjective tinnitus will be enrolled. Interventions: The patients will be allocated randomly to receive a TCM formula (BHT, Bushen Huoxue Tongluo) and informative counseling or informative counseling alone. The oral BHT herbal granules will be taken twice per day continuously for 8 weeks. Main outcome measures: The primary outcomes include recruitment rate, intervention completion rate, and data completion rate to evaluate the feasibility. The secondary outcomes include Tinnitus Handicap Inventory, tinnitus functional index, tinnitus sensation level, self-rated visual analogue scale on tinnitus loudness and annoyance, Pittsburgh Sleep Quality Index, Hospital Anxiety and Depression Scale, and adverse event. The outcome measures will be collected at baseline, end of treatment, and 4-week follow-up. Discussion: This trial is currently ongoing and is recruiting patients. The expected study results will find some preliminary evidence about the clinical effectiveness of BHT on chronic tinnitus and will also determine if it is feasible to conduct a full-scale RCT of BHT and identify the necessary changes to the protocol if possible.

Oro-pharyngo-esophageal radionuclide scintigraphy predicts aspiration pneumonia risk and associated survival in post-irradiated nasopharyngeal carcinoma patients.

OBJECTIVE: To demonstrate that oro-pharyngo-esophageal radionuclide scintigraphy (OPERS) not only detects tracheobronchial aspiration after swallowing, but also quantifies the amount of aspiration and subsequent clearance. METHODS: Data collected between 2014 and 2019 were reviewed for aspiration pneumonia at 12 and 24-months after OPERS. The predictive value for aspiration pneumonia on flexible endoscopic evaluation of swallowing (FEES), videofluoroscopic swallowing study (VFSS), and OPERS, and the overall survival of patients with or without aspiration were determined. RESULTS: Thirty-seven patients treated with radiotherapy for nasopharyngeal carcinoma (NPC) were reviewed. The incidence of aspiration detected on FEES, VFSS, and OPERS was 78.4%, 66.7%, and 44.4%, respectively. Using VFSS as a gold standard, the sensitivity and specificity of OPERS for aspiration was 73.7% and 100%. The positive and negative predictive values for aspiration were 100% and 66.7%, respectively, with an overall accuracy of 82.8%. A history of aspiration pneumonia was one factor associated with a higher chance of subsequent aspiration pneumonia within 12 months (odds ratio: 15.5, 95% CI 1.67-145.8, p < .05) and 24 months (odds ratio: 23.8, 95% CI 3.69-152.89, p < .01) of the swallowing assessment. Aspiration detected by OPERS was a significant risk factor for future aspiration pneumonia at 12 and 24 months respectively. Significantly, better survival was associated with an absence of aspiration on OPERS only, but not on FEES or VFSS. CONCLUSION: OPERS predicts the safety of swallowing, the incidence of subsequent aspiration pneumonia, and the survival prognosis in post-irradiated NPC dysphagia patients. LEVEL OF EVIDENCE: 3.

The emerging role of transcription factor FOXP3 in thyroid cancer.

Transcription factor FOXP3 is a crucial regulator in the development and function of regulatory T cells (Treg) that are essential for immunological tolerance and homeostasis. Numerous studies have indicated the correlation of tumor infiltrating FOXP3+ Treg upregulation with poor prognostic parameters in thyroid cancer, including lymph node metastases, extrathyroidal extension, and multifocality. Most immune-checkpoint molecules are expressed in Treg. The blockage of such signals with checkpoint inhibitors has been approved for several solid tumors, but not yet for thyroid cancer. Thyroid abnormalities may be induced by checkpoint inhibitors. For example, hypothyroidism, thyrotoxicosis, painless thyroiditis, or even thyroid storm are more frequently associated with anti-PD-1 antibodies (pembrolizumab and nivolumab). Therefore, Targeting FOXP3+ Treg may have impacts on checkpoint molecules and the growth of thyroid cancer. Several factors may impact the role and stability of FOXP3, such as alternative RNA splicing, mutations, and post-translational modification. In addition, the role of FOXP3+ Treg in the tumor microenvironment is also affected by the complex regulatory network formed by FOXP3 and its transcriptional partners. Here we discussed how the expression and function of FOXP3 were regulated and how FOXP3 interacted with its targets in Treg, aiming to help the development of FOXP3 as a potential therapeutic target for thyroid cancer.
