RESUMEN

INTRODUCTION: Traditional on-site missions of plastic surgeons from "high-income countries" in "low- and middle-income countries" are often limited in time and lack proper follow-up. Regular digital collaboration could lead to a more impactful and durable exchange of knowledge for plastic surgeons and residents in both settings. AIMS: The aim of this study was to evaluate the satisfaction of the first twelve months of weekly digital meetings, explore advantages/disadvantages, and to provide tools for similar initiatives. METHODS: Weekly meetings started from August 2021. An encrypted digital connection allowed residents and plastic surgeons from Uganda and the Netherlands to discuss cases for educational purposes, where treatment options were considered. After twelve months, a survey was sent to participants from both countries to indicate the meetings' strengths, weaknesses, and possible improvements. RESULTS: A total of 18 participants responded to the questionnaire (ten plastic surgeons, six residents, and two researchers). The strengths of the meetings were the accessibility of the meetings, knowledge exchange and practice for residents' final exams. Possible improvements included having a clear format for patient discussion, a session moderator and better internet connectivity. Moreover, a database to assess the impact of the given intervention on the patient cases by evaluating postoperatively (e.g. three months), could further improve clinical care. CONCLUSIONS: Virtual patient discussions subjectively contributed to medical education at both locations. Improved digital infrastructure and a collaborative database could further maximize learning capacity. Furthermore, digital proctoring is a promising way to establish sustainable collaborations between high- and low-resource countries.

RESUMEN

INTRODUCTION: The coronavirus 2019 pandemic urged us to find alternatives for education through remote proctoring and international surgical collaborations among high-, middle-, and low-income countries. Smart surgical glasses are promising for remote surgical education and international surgical collaborations. AIMS: This study aimed to assess the usability of smart surgical glasses during cleft surgery and explore their potential in remote surgical education and collaboration. METHODS: Six plastic surgical cases were randomly selected and recorded using the RODS&CONES glasses in 4K (3840 × 2160p). A 23-point questionnaire was sent to one plastic surgeon, one plastic surgery resident, and eight doctors who were not trained to critically appraise the video and audio quality of the smart surgical glasses and their applicability for remote surgical education. RESULTS: The participants indicated that the smart glasses had several significant advantages over conventional on-site education, such as facilitating a better view of the surgical field and providing possibilities for remote interaction. The audio quality was considered excellent. The main limitations were image stabilization issues and loss of video connection due to weak wireless fidelity. CONCLUSIONS: All participants appreciated the use of smart glasses for remote education and considered them a promising tool for enhancing the quality of surgical education. The glasses can enable remote assistance and education of local surgical residents and may facilitate sustainable surgical collaborations among high-, middle-, and low-income countries.

RESUMEN

PURPOSE: This study investigated specific risk factors for recurrent surgery of ulnar nerve entrapment (ie, ipsilateral clinical symptoms within 5 years after initial cubital tunnel release [CuTR]) in a large cohort. We hypothesized that recurrence is associated with lifestyle variables (eg, smoking, drinking alcohol, a high body mass index [BMI]) or comorbidities). METHODS: A retrospective cohort study was performed using the Current Procedural Terminology codes for all patients who underwent CuTR between January 2012 and November 2018. Demographic data, including sex, age, weight, height, BMI, comorbidities, smoking, and alcohol consumption, were collected. The primary outcome was the need for revision surgery after initial CuTR. Univariate and multivariate analyses were performed to identify potential risk factors for revision surgery. RESULTS: Of the 678 patients who underwent CuTR, 120 patients (18%) needed revision surgery within 5 years. Sixty-six patients required subfascial transposition (55%) and 47 patients (39%) received in situ releases. Also, sex, BMI, smoking, alcohol consumption, and comorbidities (except for spinal disc herniation) were similar between the primary and revision subgroup. Age at first occurrence was significantly lower in the revision group (48 years for revision vs 52 years for primary surgery). Moreover, cervical spinal disc herniation was associated with revision surgery (13% vs 6% in the primary group). CONCLUSIONS: Age and medical history of cervical spinal disc herniation are associated with an increased risk of revision surgery. More importantly, BMI, smoking, alcohol consumption, and other comorbidities are not associated with increased risk of revision surgery within our sample. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

RESUMEN

Differentiated thyroid carcinoma (DTC) is the most common endocrine cancer. Particularly the incidence of small clinically indolent tumors has been increasing significantly during the last decades because of increased diagnostic scrutiny, while the DTC-related mortality remained unchanged. In light of the increased awareness of the significant risk of detecting clinically indolent tumors and the potential harm and burden associated with overly diagnosis and the treatment, the approach towards management of DTC recently underwent a critical appraisal. The focus lays on reducing the unnecessary burden for patients with very low risk DTC and the correct identification of those who require treatment that is more intensive and/or follow-up. Management of DTC includes a range of different modalities, making multidisciplinary collaboration expedient. In this review, we elaborate on the recent developments in diagnosis, staging and management of DTC with specific focus on the more individualized risk assessment-based approach.

RESUMEN

Background: Sorafenib and lenvatinib are multikinase inhibitors (MKIs) approved for patients with radioactive iodine-refractory (RAI-R) differentiated thyroid cancer (DTC). There is no consensus on when to initiate MKI treatment. The objective of this study was to evaluate time to symptomatic progression (TTSP) in patients with RAI-R DTC for whom the decision to treat with an MKI was made at study entry. Methods: International, prospective, open-label, noninterventional cohort study (NCT02303444). Eligible patients had asymptomatic progressive RAI-R DTC, with ≥1 lesion ≥1 cm in diameter and life expectancy ≥6 months. The decision to treat with an MKI was at the treating physician's discretion. Primary endpoint was TTSP from study entry. Two cohorts were evaluated: patients for whom a decision to initiate an MKI was made at study entry (Cohort 1) and patients for whom there was a decision not to initiate an MKI at study entry (Cohort 2). Cohorts were compared descriptively. Results: The full analysis set (FAS) comprised 647 patients. The median duration of observation was 35.5 months (range <1-59.4). Of 344 MKI-treated patients, 209 received sorafenib, 191 received lenvatinib, and 19 received another MKI at some point. Median TTSP was 55.4 months (interquartile range [IQR] 18.6-not estimable [NE]) overall, 55.4 months (IQR 15.2-NE) in Cohort 1 (n = 169), and 51.4 months (IQR 20.0-NE) in Cohort 2 (n = 478). TTSP ≥36 months was achieved in 64.5% of patients overall, 59.5% of patients in Cohort 1, and 66.4% of patients in Cohort 2. Median overall survival from classification as RAI-R was 167 months and median progression-free survival from start of MKI therapy was 19.2 months and from start of sorafenib therapy 16.7 months. Among sorafenib-treated patients, 70% had dose modifications, 35% had a dose reduction, 89% experienced ≥1 treatment-emergent adverse event (TEAE), and 82% experienced ≥1 drug-related TEAE. Conclusions: This real-world study provides valuable insight into outcomes in patients with asymptomatic, progressive RAI-R DTC under observation or receiving MKI treatment. TTSP in the FAS provides insight into the current prognosis for patients with RAI-R DTC in the era of MKIs. Registration: NCT02303444.

RESUMEN

BACKGROUND: To investigate associations between psychological problems and the use of healthcare and informal care and total costs among head and neck cancer (HNC) patients. METHOD: Data were used of the NETherlands QUality of Life and Biomedical Cohort study. Anxiety and depression disorder (diagnostic interview), distress, symptoms of anxiety and depression (HADS), and fear of cancer recurrence (FCR) and cancer worry scale (CWS) were measured at baseline and at 12-month follow-up. Care use and costs (questionnaire) were measured at baseline, 3-, 6-, 12-, and 24-month follow-up. Associations between psychological problems and care use/costs were investigated using logistic and multiple regression analyses. RESULTS: Data of 558 patients were used. Distress, symptoms of anxiety or depression, FCR, and/or anxiety disorder at baseline were significantly associated with higher use of primary care, supportive care, and/or informal care (odds ratios (ORs) between 1.55 and 4.76). Symptoms of anxiety, FCR, and/or depression disorder at 12-month follow-up were significantly associated with use of primary care, supportive care, and/or informal care (ORs between 1.74 and 6.42). Distress, symptoms of anxiety, and FCR at baseline were associated with higher total costs. DISCUSSION: HNC patients with psychological problems make more use of healthcare and informal care and have higher costs. This is not the result of worse clinical outcomes.

RESUMEN

Modern use of post-operative radioactive iodine (RAI) treatment for differentiated thyroid cancer (DTC) should be implemented in line with patients' risk stratification. Although beneficial effects of radioiodine are undisputed in high-risk patients, controversy remains in intermediate-risk and some low-risk patients. Since the last consensus on post-surgical use of RAI in DTC patients, new retrospective data and results of prospective randomized trials have been published, which have allowed the development of a new European Thyroid Association (ETA) statement for the indications of post-surgical RAI therapy in DTC. Questions about which patients are candidates for RAI therapy, which activities of RAI can be used, and which modalities of pre-treatment patient preparation should be used are addressed in the present guidelines.

RESUMEN

BACKGROUND: This study assessed the course of fear of cancer recurrence (FCR) in patients newly diagnosed with head and neck cancer (HNC), identified FCR trajectories and factors associated with FCR trajectories. METHODS: Six hundred and seventeen HNC patients from the NET-QUBIC cohort study completed the Cancer Worry Scale-6 at diagnosis, 3 and 6 months post-treatment. FCR trajectories were identified using Latent Class Growth Analysis. Associations were explored between FCR trajectories and baseline demographic and medical variables, coping and self-efficacy. RESULTS: Overall, FCR decreased slightly between baseline and 3 months post-treatment and remained stable up to 6 months. Two FCR trajectories were identified: "high stable" (n = 125) and "low declining" (n = 492). Patients with high stable FCR were younger, reported more negative adjustment, passive coping, and reassuring thoughts, and less avoidance. CONCLUSIONS: The majority of HNC patients have low declining FCR after diagnosis, but one in five patients experience persistent high FCR up to 6 months post-treatment.

RESUMEN

BACKGROUND: Neurocognition and speech, relevant domains in head and neck cancer (HNC), may be affected pretreatment. However, the prevalence of pretreatment deficits and their possible concurrent predictors are poorly understood. METHODS: Using an HNC prospective cohort (Netherlands Quality of Life and Biomedical Cohort Study, N ≥ 444) with a cross-sectional design, we investigated the estimated prevalence of pretreatment deficits and their relationship with selected demographic, behavioral, and disease-related factors. RESULTS: Using objective assessments, rates of moderate-to-severe neurocognitive deficit ranged between 4% and 8%. From patient-reported outcomes, 6.5% of patients reported high levels of cognitive failures and 46.1% reported speech deficits. Patient-reported speech functioning was worse in larynx compared to other subsites. Other nonspeech outcomes were unrelated to any variable. Patient-reported neurocognitive and speech functioning were modestly correlated, especially in the larynx group. CONCLUSIONS: These findings indicate that a subgroup of patients with HNC shows pretreatment deficits, possibly accentuated in the case of larynx tumors.

RESUMEN

OBJECTIVES: To investigate associations between testosterone and patient reported sexual problems and need for sexual care in head and neck cancer patients at time of diagnosis and 6 months after treatment. PATIENTS AND METHODS: Data and samples were used of 40 patients (20 men, 20 women) before and 6 months after treatment. Outcome measures were total testosterone level (TT) and free testosterone index (FTI), testosterone insufficiency (TI), the EORTC QLQ-HN35 Sexuality subscale, the subscales of the International Index of Erectile Function (IIEF), Female Sexual Function Index (FSFI), and the Sexuality subscale of the Short-Form Supportive Care Needs Survey (SCNS-SF34). RESULTS: In men, higher FTI before treatment was significantly associated with better IIEF Orgasm (p = 0.020) and at 6 months follow-up with IIEF Desire (p = 0.019). Before treatment, insufficient testosterone was present in 5 males (25%) and in 3 at follow-up (15%) (2 patients who had TI before treatment plus one). In women, higher TT at follow-up was significantly associated with better EORTC Sexuality (p = 0.031) and FSFI Satisfaction (p = 0.020); FTI at follow-up was associated with FSFI Satisfaction (p = 0.012). Before treatment, TI was present in 2 women (10%) and in 3 (15%) at follow-up (the same 2 patients plus one). CONCLUSION: This pilot study showed that testosterone seems to be associated with patient reported sexual outcomes among male and female head and neck cancer patients. It is estimated that 10-25% of HNC patients may have testosterone insufficiency before treatment and/or at 6 months after treatment.

RESUMEN

Background: The American Thyroid Association (ATA), the European Association of Nuclear Medicine, the European Thyroid Association, and the Society of Nuclear Medicine and Molecular Imaging have established an intersocietal working group to address the current controversies and evolving concepts in thyroid cancer management and therapy. The working group annually identifies topics that may significantly impact clinical practice and publishes expert opinion articles reflecting intersocietal collaboration, consensus, and suggestions for further research to address these important management issues. Summary: In 2019, the intersocietal working group identified the following topics for review and interdisciplinary discussion: (i) perioperative risk stratification, (ii) the role of diagnostic radioactive iodine (RAI) imaging in initial staging, and (iii) indicators of response to RAI therapy. Conclusions: The intersocietal working group agreed that (i) initial patient management decisions should be guided by perioperative risk stratification that should include the eighth edition American Joint Committee on Cancer staging system to predict disease specific mortality, the modified 2009 ATA risk stratification system to estimate structural disease recurrence, with judicious incorporation of molecular theranostics to further refine management recommendations; (ii) diagnostic RAI scanning in ATA intermediate risk patients should be utilized selectively rather than being considered mandatory or not necessary for all patients in this category; and (iii) a consistent semiquantitative reporting system should be used for response evaluations after RAI therapy until a reproducible and clinically practical quantitative system is validated.

RESUMEN

OBJECTIVES: Patients with head and neck cancer (HNC) often report disturbances in their sleep quality, impairing their quality of life. This study aims to examine the trajectories of sleep quality from diagnosis up to 6-month after treatment, as well as the pre-treatment risk factors for poor sleep trajectories. MATERIALS AND METHODS: Sleep quality (Pittsburgh sleep quality index) was measured shortly after diagnosis (pre-treatment), and at 3 and 6 months after finishing treatment. Patients were categorized into 5 trajectory groups. We examined the association of sleep quality trajectories with sociodemographic and clinical characteristics, coping style, HNC symptoms, and psychological distress. RESULTS: Among 412 included patients, about a half either had a persistent good sleep (37.6%) or an improving (16.5%) trajectory. About a third had a persistent poor sleep (21.8%) or worsening (10.9%) sleep trajectory. The remaining patients (13.1%), alternated between good and poor sleep. Using persistent good sleep as a reference outcome, persistent poor sleepers were more likely to be woman (odds ratio [OR] = 1.98, 95% confidence interval [CI] 1.01-3.90), use painkillers prior to treatment (OR = 2.52, 95% CI 1.33-4.77), and have more pre-treatment anxiety symptoms (OR = 1.26, 95% CI 1.15-1.38). CONCLUSION: Unfavorable sleep quality trajectories are prevalent among HNC patients from pre-treatment to 6-month after treatment. A periodic sleep evaluation starting shortly after HNC diagnosis is necessary to identify persistent sleep problems, especially among high-risk group.

RESUMEN

The endocrine and the immune systems interact by sharing receptors for hormones and cytokines, cross-control and feedback mechanisms. To date, no comprehensive study has assessed the impact of thyroid hormones on immune homeostasis. By studying immune phenotype (cell populations, antibody concentrations, circulating cytokines, adipokines and acute-phase proteins, monocyte-platelet interactions and cytokine production capacity) in two large independent cohorts of healthy volunteers of Western European descent from the Human Functional Genomics Project (500FG and 300BCG cohorts), we identified a crucial role of the thyroid hormone thyroxin (T4) and thyroid-stimulating hormone (TSH) on the homeostasis of lymphocyte populations. TSH concentrations were strongly associated with multiple populations of both effector and regulatory T cells, whereas B-cell populations were significantly associated with free T4 (fT4). In contrast, fT4 and TSH had little impact on myeloid cell populations and cytokine production capacity. Mendelian randomization further supported the role of fT4 for lymphocyte homeostasis. Subsequently, using a genomics approach, we identified genetic variants that influence both fT4 and TSH concentrations and immune responses, and gene set enrichment pathway analysis showed enrichment of fT4-affected gene expression in B-cell function pathways, including the CD40 pathway, further supporting the importance of fT4 in the regulation of B-cell function. In conclusion, we show that thyroid function controls the homeostasis of the lymphoid cell compartment. These findings improve our understanding of the immune responses and open the door for exploring and understanding the role of thyroid hormones in the lymphocyte function during disease.

RESUMEN

BACKGROUND: Head and neck cancer (HNC) patients often suffer from distress attributed to their cancer diagnosis which may disturb their sleep. However, there is lack of research about poor sleep quality among newly diagnosed HNC patients. Therefore, our aim was to investigate the prevalence and the associated factors of poor sleep quality among HNC patients before starting treatment. MATERIALS AND METHODS: A cross-sectional study was conducted using the baseline data from NET-QUBIC study, an ongoing multi-center cohort of HNC patients in the Netherlands. Poor sleep quality was defined as a Pittsburgh Sleep Quality Index (PSQI) total score of > 5. Risk factors examined were sociodemographic factors (age, sex, education level, living situation), clinical characteristics (HNC subsite, tumor stage, comorbidity, performance status), lifestyle factors, coping styles, and HNC symptoms. RESULTS: Among 560 HNC patients, 246 (44%) had poor sleep quality before start of treatment. Several factors were found to be significantly associated with poor sleep: younger age (odds ratio [OR] for each additional year 0.98, 95% CI 0.96-1.00), being female (OR 2.6, 95% CI 1.7-4.1), higher passive coping style (OR 1.18, 95% CI 1.09-1.28), more oral pain (OR 1.10, 95% CI 1.01-1.19), and less sexual interest and enjoyment (OR 1.13, 95% CI 1.06-1.20). CONCLUSION: Poor sleep quality is highly prevalent among HNC patients before start of treatment. Early evaluation and tailored intervention to improve sleep quality are necessary to prepare these patients for HNC treatment and its consequences.

RESUMEN

BACKGROUND: Tumor-associated macrophages (TAMs) are key components of the tumor microenvironment (TME) in non-medullary thyroid carcinoma (TC) and neuroblastoma (NB), being associated with a poor prognosis for patients. However, little is known about how tumors steer the specific metabolic phenotype and function of TAMs. METHODS: In a human coculture model, transcriptome, metabolome and lipidome analysis were performed on TC-induced and NB-induced macrophages. The metabolic shift was correlated to functional readouts, such as cytokine production and reactive oxygen species (ROS) production, including pharmacological inhibition of metabolic pathways. RESULTS: Based on transcriptome and metabolome analysis, we observed a strong upregulation of lipid biosynthesis pathways in TAMs. Subsequently, lipidome analysis revealed that tumor-induced macrophages have an increased total lipid content and enriched levels of intracellular lipids, especially phosphoglycerides and sphingomyelins. Strikingly, this metabolic shift in lipid synthesis contributes to their protumoral functional characteristics: blocking key enzymes of lipid biosynthesis in the tumor-induced macrophages reversed the increased inflammatory cytokines and the capacity to produce ROS, two well-known protumoral factors in the TME. CONCLUSIONS: Taken together, our data show that tumor cells can stimulate lipid biosynthesis in macrophages to induce protumoral cytokine and ROS responses and advocate lipid biosynthesis as a potential therapeutic target to reprogram the TME.

RESUMEN

BACKGROUND: Various surgical techniques are applied to correct prominent ears. However, there are limited data on the effect of otoplasty on patient-related outcome measures, such as cold ears and cold intolerance. This retrospective cohort study describes the occurrence of cold intolerance in 98 patients, with a total of 196 ears in a single center during 6 years (2011-2017). METHODS: In this study, 3 groups were identified: group I, anterior scoring of the cartilage (ie, Chong Chet); group II, posterior scoring of the cartilage and suture reposition of the cartilage; and group III, posterior approach without scoring (ie, Furnas and Mustardé). Parents of patients filled in a questionnaire with 40 questions to criticize the effect of surgery. RESULTS: Symptoms of cold intolerance and pain were reported in 44.4% (n = 16) in the anterior scoring group, 48.1% (n = 26) in the posterior scoring group, and 62.5% (n = 5) in the posterior approach group without scoring of the cartilage (P = 0.68). The satisfaction rate was significantly lower in the posterior group without scoring (Likert scale of 17.44 ± 22.01 anterior scoring, 16.02 ± 18.13 posterior scoring, and 11.13 ± 25.87 posterior approach without scoring; P = 0.02). CONCLUSIONS: This study underscores the fact that a great part of patients after otoplasty report symptoms of cold intolerance; however, these most often resolve and did not differ between different groups. Patients should be informed about this sequela. Furthermore, overall satisfaction rate was significantly lower in the posterior group without scoring.

RESUMEN

Recently, the management of patients with low-risk differentiated non-medullary thyroid cancer (DTC), including papillary and follicular thyroid carcinoma subtypes, has been critically appraised, questioning whether these patients might be overtreated without a clear clinical benefit. The American Thyroid Association (ATA) guideline suggests that thyroid lobectomy (TL) could be a safe alternative for total thyroidectomy (TT) in patients with DTC up to 4 cm limited to the thyroid, without metastases. We conducted a meta-analysis to assess the clinical outcomes in patients with low-risk DTC based on the extent of surgery. The risk ratio (RR) of recurrence rate, overall survival (OS), disease-free survival (DFS) and disease specific survival (DSS) were estimated. In total 16 studies with 175,430 patients met the inclusion criteria. Overall, low recurrence rates were observed for both TL and TT groups (7 vs. 7%, RR 1.10, 95% CI 0.61-1.96, I2 = 72%), and no statistically significant differences for OS (TL 94.1 vs. TT 94.4%, RR 0.99, CI 0.99-1.00, I2 = 53%), DFS (TL 87 vs. TT 91%, RR 0.96, CI 0.89-1.03, I2 = 85%), and DSS (TL 97.2 vs. TT 95.4%, RR 1.01, CI 1.00-1.01, I2 = 74%). The high degree of heterogeneity of the studies is a notable limitation. Conservative management and appropriate follow-up instead of bilateral surgery would be justifiable in selected patients. These findings highlight the importance of shared-decision making in the management of patients with small, low-risk DTC.

RESUMEN

OBJECTIVE: The observed poorer physical function in persons with mental disorders could partly be due to dysregulation in physiological stress systems. However, an integrated picture of the role of physiological stress systems on objective physical function is lacking. This study examined the association of multiple physiological stress systems with objective physical function, and explored whether these stress systems contribute to the relationship between depression/anxiety and poorer physical function. METHODS: Data of 2860 persons of the Netherlands Study of Depression and Anxiety was used. Physical function was indicated by hand grip strength assessed using a hand-held dynamometer and lung function assessed using a peak flow meter. Inflammatory markers (CRP, IL-6, TNF-α), salivary cortisol (cortisol awakening response (AUCg, AUCi), evening cortisol) and ANS markers (heartrate, PEP, RSA) were determined. Depression/anxiety disorders were determined using psychiatric interviews. Linear regression analyses were adjusted for sociodemographics, health and lifestyle factors. RESULTS: Higher inflammation levels were associated with lower hand grip strength (BCRP = -0.21(SE = 0.06), p < .001) and lower lung function (BCRP = -2.07(SE = 0.66), p = .002), BTNF-α = -3.35(SE = 1.42), p = .022). Higher salivary cortisol levels were associated with lower lung function (Bevening cortisol = -2.22(SE = 0.59), p < .001). The association, in women, between depression/anxiety disorders and poorer physical function did not significantly diminish after adjustment for physiological stress markers. CONCLUSION: This large cohort study showed that stress system dysfunction (especially the immune-inflammatory system and HPA-axis) contributes to poorer objective physical function. Stress system dysfunction did not explain the poorer physical function observed in persons with depression/anxiety disorders, suggesting that other pathways are involved to explain that association.

RESUMEN

Objective: To examine self-reported medication adherence and its association with illness perceptions, beliefs about medication and personality among thyroid cancer survivors. Methods: Individuals diagnosed with thyroid cancer between 1990 and 2008, as registered in the Eindhoven Cancer Registry, received our survey; 86% (n = 306) responded.Results: Many patients reported that they never forgot taking their medicines (n = 168; 56%), never altered the dose (n = 258; 88%), never stopped taking them (n = 291; 99%), never decided to miss a dose (n = 284; 97%) and never took less than instructed (n = 286; 97%). Fifty-two percent were classified as nonadherent; of which 14% intentional nonadherent only, 70% were nonintentional nonadherent only and 16% were both intentional and nonintentional nonadherent. Nonadherers were younger, more highly educated, more often employed, had a lower stage at diagnosis, and less often reported ≥2 comorbid conditions than adherers. Furthermore, their illness affected them more emotionally and they more often reported that their life would be impossible without their medicine. Logistic regression models showed that higher age, lower education and lower perceived necessity of medication was associated with better adherence while beliefs about medication, illness perceptions, and personality were not associated with adherence.Conclusions: Despite lifelong dependence on supplement therapy, 52% of thyroid cancer survivors were nonadherent.
