Evaluation of Quality of Life in Patients with Differentiated Thyroid Cancer by Means of the Thyroid-Specific Patient-Reported Outcome Questionnaire: A 5-Year Longitudinal Study

Development and Effects of a Smartphone Application to Improve Self-Management in Workers Who Underwent Thyroid Cancer Surgery

BACKGROUND

Although the survival rate for thyroid cancer is high, a nursing intervention that enhances autonomous motivation is needed for patients with jobs to improve their long-term self-management abilities in the early postoperative period.

OBJECTIVES

This study aims to develop a mobile application (app) based on the Self-Determination Theory for patients returning to work after thyroid cancer surgery and to verify its effectiveness.

METHODS

We developed an app to promote self-management and verify its effectiveness after 12 weeks in early outpatients who underwent thyroid cancer surgery through a randomized controlled trial design. In addition to a subjective questionnaire, objective data on steps, stress, and sleep quality from a smartwatch are analyzed.

RESULTS

Autonomous motivation (t = -2.11, P = .040), perceived health status (t = -2.05, P = .048), and perceived stress (t = 2.18, P = .039) show significant differences in the experimental group compared to the control group. Objective data collected using a smartwatch show that stress scores (t = 5.43, P = .006) and sleep quality scores (t = 3.83, P = .025) in the experimental group are significantly improved compared to those in the control group.

CONCLUSION

Among workers in the early stages after thyroid cancer surgery, using the smartphone app strengthens autonomous motivation and improves steps, stress levels, and sleep quality, making it an effective nursing intervention for self-management.

IMPLICATIONS FOR PRACTICE

In outpatient nursing practice, self-management should be promoted using a smartphone app among adult patients returning to work soon after thyroid cancer surgery.

Five-Year Follow-Up of Health-Related Quality of Life in Differentiated Thyroid Cancer Patients Treated with Total Thyroidectomy and Radioiodine in Sweden: A Nationwide Prospective Cohort Study

Background: Despite a good prognosis, survivors of differentiated thyroid cancer (DTC) may have reduced health-related quality of life (HRQOL) many years after treatment, and it is unclear how suppression of thyroid-stimulating hormone (TSH) may contribute to HRQOL. This study investigated changes in HRQOL in the 5 years following DTC treatment, the association between HRQOL and TSH suppression, and how HRQOL compares to the general population. Methods: In this nationwide prospective cohort study, 487 patients with DTC were identified between 2012 and 2017 from all Swedish hospitals treating patients with DTC. Patients treated with total thyroidectomy and planned for radioiodine answered the Swedish version of the Short Form-36 Health Survey (SF-36) and a study specific questionnaire at treatment and after 1, 3, and 5 years. Summary measures for physical and mental QOL were derived from the SF-36, and TSH values were collected from patient records. To study changes in HRQOL over time, linear mixed models were fitted on multiply imputed data, with all patients and measurement points included in the model. Results: In total, 351 patients consented to participate in the study. In the 5 years following DTC treatment, physical QOL did not change significantly with time, while mental QOL improved by on average 0.61 (p < 0.001) per year. TSH levels were not predictive of either physical or mental QOL, or their change over time. At 5 years, there was a significant difference in physical and mental QOL compared with the Swedish general population, but effect sizes were small (Cohen's d = 0.29 and -0.21, respectively). The SF-36 domains general health, vitality, social functioning, and mental health were lower at 5 years compared with the general population (difference 8.7-13.3), and these differences were clinically significant. Conclusions: The mental component of HRQOL improves over time following DTC treatment. HRQOL in patients with DTC is not explained by TSH suppression. Although overall differences in physical and mental HRQOL compared with the general population were small 5 years after treatment, several specific psychosocial HRQOL domains were clinically meaningfully reduced. Psychosocial health issues should be screened for during DTC follow-up.

Longitudinal Changes in Quality of Life Before and After Thyroidectomy in Patients With Differentiated Thyroid Cancer

OBJECTIVE

The objective of this prospective study was to assess longitudinal variations in health-related quality of life (HR-QOL) in patients diagnosed with differentiated thyroid cancer (DTC) before and after thyroidectomy.

METHODS

A cohort of 185 DTC patients who underwent thyroidectomy between January 2013 and December 2017 and who completed all necessary questionnaires was evaluated. Their HR-QOL was gauged using the University of Washington Quality of Life questionnaire (UW-QOL) and the City of Hope Quality of Life-Thyroid Version questionnaire (QOL-TV) both prior to surgery and at 3 months, 6 months, 1 year, 2 years, 3 years, and 5 years postoperatively.

RESULTS

Out of 185 patients, 150 (81.1%) were female, with an average age of 48.7 ± 12.9 years. For both UW-QOL and QOL-TV, the total composite QOL scores notably declined from preoperative levels to 3 months postoperatively, then gradually improved over 5 years, ultimately exceeding preoperative scores. Factors such as total thyroidectomy, radioactive iodine (RAI) ablation, and postoperative hypoparathyroidism were associated with lower physical composite QOL scores. Patients who underwent remote-access thyroidectomy expressed significantly higher satisfaction with appearance compared with those who had conventional thyroidectomy. Mood and anxiety were major clinical concerns both before and after surgery, showing considerable improvement postoperatively.

CONCLUSION

For DTC patients, HR-QOL experienced a significant drop 3 months postsurgery, subsequently showing gradual improvement, surpassing preoperative QOL by 5 years. Factors contributing to improved physical QOL included the utilization of remote-access thyroidectomy, less extensive thyroidectomy, and the absence of RAI ablation and hypoparathyroidism.

Status of mental and social activities of young and middle-aged patients after papillary thyroid cancer surgery

Background

Papillary thyroid cancer (PTC) is prevalent among younger populations and has a favorable survival rate. However, a significant number of patients experience psychosocial stress and a reduced quality of life (QoL) after surgical treatment. Therefore, comprehensive evaluations of the patients are essential to improve their recovery.

Methods

The present study enrolled 512 young and middle-aged patients diagnosed with PTC who underwent surgery at our institution between September 2020 and August 2021. Each participant completed a series of questionnaires: Generalized Anxiety Disorder 7 (GAD-7), European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), Thyroid Cancer-Specific Quality of Life Questionnaire (THYCA-QoL), and Readiness to Return-to-Work Scale (RRTW).

Results

GAD-7 data showed that almost half of the study subjects were experiencing anxiety. Regarding health-related quality of life (HRQoL), participants reported the highest levels of fatigue, insomnia, voice problems, and scarring, with patients in anxious states reporting worse symptoms. Based on RRTW, more than half of the subjects had returned to work and had better HRQoL compared to the others who were evaluating a possible return to work. Age, gender, BMI, education, diet, residence, health insurance, months since surgery, monthly income, and caregiver status were significantly correlated with return to work. Additionally, having a caregiver, higher monthly income, more time since surgery, and living in a city or village were positively associated with return to work.

Conclusion

Young and middle-aged patients with PTC commonly experience a range of health-related issues and disease-specific symptoms following surgery, accompanied by inferior psychological well-being, HRQoL, and work readiness. It is crucial to prioritize timely interventions targeting postoperative psychological support, HRQoL improvement, and the restoration of working ability in PTC patients.

Quality of Life in Patients With Well-Differentiated Thyroid Carcinoma After Total Thyroidectomy in Greece

INTRODUCTION

Well-differentiated thyroid cancer is among the most common types of endocrine cancer. Despite its increasing prevalence, the prognosis of thyroid cancer is rather good, with a five-year survival rate ranging between 80% and 90%, depending on the histological type. Not only the post-treatment complications and the side effects of the lifelong medication but also the possibility of a recurrence may have a negative impact on the patient's quality of life (QoL).

OBJECTIVE

The aim of this study is to investigate the impact of total thyroidectomy on the QoL of patients with well-differentiated thyroid carcinoma.

METHODS

A prospective study was performed in patients who underwent total thyroidectomy due to well-differentiated thyroid carcinoma in the Otolaryngology-Head and Neck Surgery Department at the University Hospital of Larissa, Greece. The QoL was evaluated based on the "Quality of Life (Thyroid Version)" questionnaire.

RESULTS

One hundred patients participated in the study, with a mean age of 51.24±15.33 years. Of these, 63 (63%) were females and 37 (37%) were males. Social concerns, physical well-being, and psychological well-being presented a gradual positive alteration during the first 12 months after the surgery, with psychological well-being reporting the most significant progress of 15.3%. However, spiritual well-being appeared to decline over time. The younger patients progressively improved their physical, psychological, and mental well-being; however, the older patients showed an amelioration of their social skills. Female patients reported higher levels of spiritual well-being, whereas males developed better social skills.

CONCLUSIONS

In the long term, total thyroidectomy can ameliorate patients' physical status, psychological well-being, and social concerns. However, it might have a negative effect on their mental health during the first 12 months postoperatively. In addition, QoL is directly influenced by demographic characteristics such as age and gender.

The "not so good" thyroid cancer: a scoping review on risk factors associated with anxiety, depression and quality of life

The incidence of thyroid cancer has increased in recent years, leading to a growing number of survivors facing lifelong consequences. This scoping review investigated anxiety, depression, and quality of life (QoL) in thyroid cancer survivors compared to the general population, those with benign pathology, and survivors of other types of cancers. Moreover, we aimed to identify the risk factors associated with anxiety, depression, and QoL in thyroid cancer patients. A total of 727 articles were identified through PubMed, ProQuest, Cochrane, and Google Scholar databases, and 68 articles that met the criteria were selected for data extraction. Thyroid cancer survivors have a poorer QoL compared to the general population, population with benign pathology, and survivors of other types of cancer associated with worse clinical outcomes. The main risk factors are grouped into socioeconomic factors, disease-specific factors, management factors, comorbidities, and patient perceptions. Effective communication between the patient and the medical team and behavioral interventions may reduce these risks. Despite the common perception of thyroid cancer as a "good cancer," the findings of this review demonstrate the need to address the risk factors associated with increased anxiety, depression, and lower QoL in survivors.

Changes in quality of life after thyroidectomy in subjects with thyroid cancer in relation to the dose of levothyroxine

PURPOSE

Previous studies demonstrated decreased quality of life (QoL) in differentiated thyroid cancer (DTC) survivors and suggested QoL variability related to time from thyroidectomy and levothyroxine dosage. The aims of this study were to evaluate QoL in thyroidectomized subjects in different levothyroxine states and to evaluate the association between TSH and thyroid hormones and QoL.

METHODS

Prospective 5-year study enrolling 208 patients thyroidectomized for DTC, studied in one to four times according to levothyroxine dosage: withdrawal (WITHD), complete (C-SUPP) and mild TSH-suppression (M-SUPP), replacement (REPL). Each patient was allowed to participate into the study more than one time. A total of 300 evaluations were collected, consisting of detailed thyroid hormone profile and QoL assessment through the ThyPRO questionnaire.

RESULTS

Comparing the four groups, significant differences were found for anxiety, impaired social and daily life and item 12 (overall impact of thyroid disease) domains (p < 0.05). Interestingly, C-SUPP subjects reported the best scores in almost all ThyPRO scales. Significant correlations were found between QoL and pituitary-thyroid axis function, as well as between QoL and gender, being females more affected. At multiple regression analyses fT3 demonstrated to be the best explanatory factor for overall impact of thyroid disease on the patient's life, followed by gender.

CONCLUSIONS

TSH-suppressive doses of levothyroxine are more effective in improving QoL in DTC patients after thyroidectomy. These results confirm the urgent need of further studies aimed to define the best treatment of hypothyroidism, effective on well-being and harmless for patients.

Analysis of Unmet Information Needs Among Patients With Thyroid Cancer

Importance

Counseling prior to thyroid cancer (TC) treatment is an essential component of informed consent. An informed patient affects treatment-related expectations and patient engagement, factors that contribute significantly to patient-reported quality-of-life outcomes.

Objective

To describe experiences with pretreatment counseling among survivors of TC and to test factors associated with self-reported treatment meeting expectations.

Design, Setting, and Participants

A cross-sectional survey was administered between October 18, 2019, and February 8, 2020, to members of ThyCa: Thyroid Cancer Survivors' Association Inc, and to individuals accessing the public-facing ThyCa website. Survey respondents were asked 55 questions, including 4 free-text questions and 2 multiple-choice questions about pretreatment counseling.

Main Outcomes and Measures

Respondents self-reported (1) their unmet information needs, (2) rates of treatment meeting expectations, and (3) rates of treatment understanding. A mixed-methods analysis was performed, including qualitative content analysis of free-text responses and multivariable logistic regression of factors associated with self-reported levels of treatment meeting expectations.

Results

Of the 1412 survey respondents, 1249 were women (88.4%). The median age at diagnosis was 48 years (range, 18-85 years), and the median age at the time of survey completion was 60 years (range, 18-87 years). A total of 1259 respondents (89.2%) provided free-text responses to the question, "What would you tell someone newly diagnosed with your same condition?" Of these individuals, 526 (37.2%) reported inadequate pretreatment plan understanding and 578 (40.9%) reported that their treatment experience did not meet their expectations. Treatment met expectations for only 95 respondents (18.1%) reporting an inadequate pretreatment plan understanding. Of the 526 survivors of TC reporting a lack of understanding, 473 (90.0%) provided additional textual comments, most commonly in the categories of postoperative treatment, surveillance, and treatment effects. On multivariable logistic regression, self-reported failure to have an understanding of TC treatment was independently associated with failure of treatment to meet expectations (odds ratio, 5.1 [95% CI, 3.7-6.9]). Patients reporting a full understanding of their treatment plan were 5-fold more likely to indicate that their initial treatment experience was on par with expectations, independent of reported postoperative complications, age, sex, and other potential confounders.

Conclusions and Relevance

In this survey study, a substantial proportion of survivors of TC reported inadequate pretreatment understanding. This gap in understanding was associated with high levels of self-reported failure of treatment to meet expectations, which in turn is associated in other studies with poorer patient-reported quality-of-life outcomes. These outcomes may be improved by addressing gaps in patient understanding so expectations more closely match TC diagnosis and treatment pathways.

Health-related quality-of-life analyses from a multicenter, randomized, double-blind phase 2 study of patients with differentiated thyroid cancer treated with lenvatinib 18 or 24 mg/day

BACKGROUND

In the phase 2 double-blind Study 211, a starting dose of lenvatinib 18 mg/day was compared with the approved starting dose of 24 mg/day in patients with radioiodine-refractory differentiated thyroid cancer (RR-DTC). Predefined criteria for noninferiority for efficacy in the 18 mg arm were not met; safety was similar in both arms. Impact of lenvatinib treatment on health-related quality-of-life (HRQoL) was a secondary endpoint of Study 211.

METHODS

Patients with RR-DTC were randomly assigned to a blinded starting dose of lenvatinib 18 mg/day or 24 mg/day. HRQoL was assessed at baseline, every 8 weeks until Week 24, then every 16 weeks, and at the off-treatment visit, using the EQ-5D-3L and FACT-G instruments. Completion and compliance rates, mean change from baseline, and times to first and definitive deterioration were evaluated.

RESULTS

Baseline EQ-5D and FACT-G scores, and overall changes from baseline, were comparable between patients in the lenvatinib 18 mg/day (n = 77) and 24 mg/day arms (n = 75). For the 18 mg versus 24 mg arms, least squares mean differences were -0.42 (95% CI -4.88, 4.03) for EQ-5D-VAS and 0.47 (95% CI -3.45, 4.39) for FACT-G total. Time to first deterioration did not significantly favor either arm; EQ-5D-VAS HR [18 mg/24 mg] 0.93 (95% CI 0.61-1.40), EQ-5D-HUI HR [18 mg/24 mg] 0.68 (95% CI 0.44-1.05), FACT-G total HR [18 mg/24 mg] 0.73 (95% CI 0.48-1.12). Time to definitive deterioration did not significantly favor either arm, though EQ-5D-VAS showed a trend in favor of the 24 mg arm (HR [18 mg/24 mg] 1.72; 95% CI 0.99-3.01); EQ-5D-HUI HR [18 mg/24 mg] was 0.96 (95% CI 0.57-1.63), FACT-G total HR [18 mg/24 mg] was 0.72 (95% CI 0.43-1.21).

CONCLUSIONS

In Study 211, HRQoL for patients in the lenvatinib 18 mg/day arm was not statistically different from that of patients in the 24 mg/day arm. These data further support the use of the approved lenvatinib starting dose of 24 mg/day in patients with RR-DTC.

Long-Term Health-Related Quality of Life Outcomes Following Thyroid Surgery for Malignant or Benign Disease: Deficits Persist in Cancer Survivors Beyond Five Years

BACKGROUND

Thyroid cancer diagnoses are increasing and treatment can lead to significant morbidity. Long-term health-related quality of life (HRQoL) in thyroid cancer is understudied and lacks reference populations. This study compares long-term HRQoL between patients with thyroid cancer or benign disease, following thyroid surgery.

METHODS

Patients undergoing thyroidectomy between 2000 and 2017 were identified from a pathology database. 696 participants (278 malignant, 418 benign) were invited to complete a validated disease-specific HRQoL tool, City of Hope-Thyroid Version. Propensity scores were used to adjust for demographic and clinical differences between cohorts.

RESULTS

206 patients (102 malignant, 104 benign), 71% female, returned surveys a median of 6.5 (range 1-19) years after thyroidectomy. Of the cancer cohort, 95% had differentiated thyroid cancer and 83% remained disease-free. There were no significant differences in overall HRQoL scores between groups. In comparison to the benign cohort, cancer patients showed a significant detriment in the social subdomain score (OR 0.10-0.96, p = 0.017) but not in other subdomains (physical, psychological, spiritual). Female gender, increasing BMI and cancer recurrence were significantly associated with decreased overall HRQoL. Compared to the benign cohort, cancer patients reported more personal and family distress associated with diagnosis and treatment, increased future uncertainty, poorer concentration and greater financial burden.

CONCLUSION

Although no difference in overall HRQoL was found between patients undergoing thyroidectomy for benign or malignant disease, detriments in social well-being may persist many years after surgery. Thyroid cancer patients and their families may benefit from increased supports around the time of diagnosis and treatment.

Anxiety and quality of life among papillary thyroid cancer patients awaiting final pathology results after surgery

PURPOSE

There is a lack of research on short-term mental health and health-related quality of life (HRQoL) in thyroid cancer patients. This study aimed to assess the short-term anxiety level and HRQoL of patients during the early postoperative period while awaiting pathology results, and to explore the important factors associated with state anxiety.

METHODS

In this single-center cross-sectional study, 349 patients with papillary thyroid cancer were included. Anxiety and HRQoL were measured using the State-Trait Anxiety Inventory (STAI) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC-QLQ-C30), respectively.

RESULTS

In general, papillary thyroid cancer patients reported good quality of life with a mean global quality of life score of 75.69 ± 20.66 (on a scale of 0-100, where 100 means the best). There was no significant difference in HRQoL between the two groups, except regarding social functioning (p = 0.027). The anxiety levels of the two groups were similar; however, the state anxiety score (42.17 ± 12.52) was significantly higher than the trait anxiety score (40.69 ± 11.18) among patients in the non-FNA group (p = 0.023). Dyspnea, insomnia, QL, and trait anxiety were independent factors that affected state anxiety.

CONCLUSION

Patients with papillary thyroid cancer had good postoperative HRQoL and a significantly higher than usual level of state anxiety while awaiting pathology results. Symptoms of dyspnea and insomnia, global quality of life, and trait anxiety are important factors associated with state anxiety. Preoperative FNA results may moderate the change in anxiety level. These findings may help clinicians provide psychological support.

Quality of Life in Patients with Benign Non-Toxic Goiter After Surgical Intervention: A Systematic Review and Meta-Analysis

BACKGROUND

Prior studies evaluating health-related quality of life (HR-QoL) outcomes in patients undergoing surgery for benign non-toxic goiter have used different instruments and time points, leading to conflicting results. We sought to systematically review the differences in HR-QoL among patients with BNTG at baseline and 6 months after surgery, using exclusively the ThyPRO questionnaire.

METHODS

A systematic search was performed using PubMed, Embase, Web of Science, Cochrane Central, CINAHL, and PsycINFO for papers reporting the assessment of HR-QoL utilizing ThyPRO. Data were meta-analyzed using a random-effects model, and pooled estimates were calculated using weighted mean differences (WMD) between baseline and 6 months after surgery. We assessed the quality and risk of bias of the studies using the Robins-I tool and previously published minimally important change (MIC) values to assess clinical significance.

RESULTS

Six papers met the predefined inclusion criteria, describing a total of 496 patients. Meta-analysis demonstrated improved QoL in all thirteen domains of ThyPRO six months post-surgical intervention compared to baseline. Specifically, the largest improvement in QoL was seen in the domains of overall QoL, WMD -25.84 (95% CI -29.70, -21.98, p < 0.001, I² = 23%), goiter symptoms, 23.96 (95% CI -30.29, -17.64, p < 0.001, I² = 91%), and tiredness, -16.20 (95% CI -19.23, -13.16, p < 0.001, I² = 3%). The differences in scores 9 of 13 domains were clinically significant based on MIC.

CONCLUSIONS

Disease-specific HR-QoL improved in all ThyPRO domains after surgery in patients with BNTG. Future studies of QoL in thyroid surgery patients will benefit from a standard questionnaire and improved reporting of covariates including complications to ensure comparability across studies.

Impact of thyroidectomy on quality of life in benign goitres: results from a prospective cohort study

PURPOSE

Benign thyroid diseases encompass a large spectrum of conditions that are chronic and subtle in nature. A majority of patients choose non-surgical management and continue living their daily lives with subconscious impairment of optimal functioning. We studied the effect of thyroidectomy on the quality of life (QoL) in patients with benign goitres.

METHODS

A prospective study was conducted on 50 patients between January 2017 and August 2018 using the ThyPRO 39 questionnaire. This is a disease-specific health-related questionnaire administered the day before surgery and 6 months following surgery. Data analysis was performed using EpiData Manager and EpiData Entry Client (v 3.1).

RESULTS

The mean age of the cohort was 43.30 years ± 11.61, with a female preponderance (34:16). The most common indications for surgery were suspicion of malignancy and compressive symptoms in 34% and 30%, respectively. The most common histopathology reported was nodular/adenomatous hyperplasia (56%). Prior to surgery, the most common domains affected were emotional susceptibility and tiredness. Following surgery, a significant improvement in all domains of the ThyPRO 39 questionnaire were seen except for psychological well-being (p=0.126). In addition, the composite scores significantly improved (p<0.001). Younger age, female gender, and longer duration of goitre were the factors that significantly affected the outcomes in various domains.

CONCLUSION

Patients with benign goitres have subtle impairment of QoL which showed significant improvement following thyroidectomy.

Health-related quality of life in long-term differentiated thyroid cancer survivors: A cross-sectional Tunisian-based study

BACKGROUND AND AIM

The incidence of differentiated thyroid cancer (DTC) has risen dramatically worldwide. Despite an excellent prognosis, the growing DTC survivors' community often features poor health-related quality of life (HRQoL), which challenges long-term DTC care, particularly in developing Southern Mediterranean and African countries. We aimed to assess the HRQoL and to investigate its determinants in disease-free Tunisian DTC survivors.

METHODS

We conducted a three-month cross-sectional study that included 266 patients diagnosed with DTC. We assessed the HRQoL in eligible participants using the short form-36 health survey, in comparison with 76 healthy controls.

RESULTS

The 86 eligible DTC survivors were predominantly female (89.5%) with an average age of 44.3 ± 12.5 years. Physical-functioning (PF), role-physical (RP), and pain domains were substantially altered compared to the reference population. Age was negatively associated with PF, RP, role-emotional (RE), and social functioning (SF). Tumor size and lymph node metastases affected general health and PF, respectively. The cancer-free survival duration was positively correlated with mental health (MH). Poor neck scar healing and persistent post-operative hypoparathyroidism significantly deteriorate MH. Pain perception was positively correlated with the radioactive iodine cumulative dose. Subclinical hyperthyroidism significantly reduced PF and RP scores. TSH suppression was negatively and strongly correlated with MH and SF scores.

CONCLUSION

HRQoL is substantially reduced in DTC survivors compared to the normative Tunisian population. These results could be extrapolated to similar individuals in other South Mediterranean and African countries. The development of coordinated multidisciplinary aftercare interventions in this region is warranted to preserve HRQoL in DTC survivors.

Systematic review of health-related quality of life following thyroid cancer

This systematic review provides a summary of all studies published between 2000 and 2019 using a health-related quality of life (HRQOL) patient-completed questionnaire to report outcomes following diagnosis and treatment of thyroid cancer. The search terms were “thyroid cancer” or “thyroid carcinoma,” “quality of life” or “health related quality of life,” and “questionnaire” or “patient reported outcome.” EMBASE, PubMed, Medline, PsycINFO, CINAHL, and HaNDLE-On-QOL search engines were searched between 2 February and 23 February 2020. A total of 811 identified articles were reduced to 314 when duplicates were removed. After exclusion criteria (not thyroid specific, no quality of life questionnaires, and conference abstracts) were applied, 92 remained. Hand searching identified a further 2 articles. Of the 94 included, 16 had a surgical, 26 a primarily medical, and 52 a general focus. There were articles from 27 countries. A total of 49 articles were published from 2015 through 2019 inclusive. A total of 72 questionnaires were used among the articles and a range of 7 to 2215 participants were included within each article. This review demonstrated an increasing number of publications annually. The scope of enquiry into aspects of HRQOL following thyroid cancer is broad, with relatively few addressing surgical aspects and many focusing on the impact of radio-iodine. More research is required into shared decision-making in initial management decisions and HRQOL and interventions aimed specifically at addressing long-term HRQOL difficulties.

A comparative cross-sectional study on sleep quality in patients with a history of differentiated thyroid carcinoma and its correlation with quality of life

PURPOSE

To evaluate sleep quality in differentiated thyroid carcinoma (DTC) patients and correlate sleep disturbances with quality of life (QoL).

METHODS

119 DTC patients were enrolled (DTC group). The Pittsburgh Sleep Quality Index (PSQI) and the Insomnia Severity Index (ISI) inventories were administered. The Thyroid-specific Patient-Reported Outcome (ThyPRO) questionnaire, the Billewicz scale (BS) and an ad-hoc visual analogic scale (VAS) were used to measure QoL and subjective therapy-related complaints. The same examinations were conducted in 53 subjects (control group) who had undergone surgery for benign thyroid pathology.

RESULTS

L-T4 dosages and TSH levels differed between the groups. BS and VAS scores were comparable. PSQI documented a similar percentage of poor sleepers in the DTC (74%) and control (62%) groups. ISI showed no difference in subjects without clinically significant insomnia: DTC (43%) and controls (48%). ThyPRO showed significantly worse scores in DTC than control subjects. In DTC patients, PSQI (P = 0.002) and ISI (P = 0.04) correlated significantly with age. In control subjects, TSH displayed a significant positive association with PSQI (P = 0.02) and ISI (P < 0.05). The ThyPRO general score correlated significantly with PSQI in DTC patients. In both groups, ISI correlated significantly with several ThyPRO scales and the ThyPRO general score. "Anxiety" and "emotional susceptibility" were the scales most significantly related with PSQI and ISI.

CONCLUSION

In disease-free DTC patients and subjects who undergo thyroid surgery for benign pathology, abnormal sleep components and insomnia are similar. The ThyPRO questionnaire closely reflects sleep disturbances in all subjects. Recognising and treating sleep disturbances might improve QoL.
