Quality of life in patients with thyroid cancer compared with the general population

The impact of electronic versus paper-based data capture on data collection logistics and on missing scores in thyroid cancer patients

PURPOSE

The purpose of this study was to investigate the impact of the type of data capture on the time and help needed for collecting patient-reported outcomes as well as on the proportion of missing scores.

METHODS

In a multinational prospective study, thyroid cancer patients from 17 countries completed a validated questionnaire measuring quality of life. Electronic data capture was compared to the paper-based approach using multivariate logistic regression.

RESULTS

A total of 437 patients were included, of whom 13% used electronic data capture. The relation between data capture and time needed was modified by the emotional functioning of the patients. Those with clinical impairments in that respect needed more time to complete the questionnaire when they used electronic data capture compared to paper and pencil (ORadj 24.0; p = 0.006). This was not the case when patients had sub-threshold emotional problems (ORadj 1.9; p = 0.48). The odds of having the researcher reading the questions out (instead of the patient doing this themselves) (ORadj 0.1; p = 0.01) and of needing any help (ORadj 0.1; p = 0.01) were lower when electronic data capture was used. The proportion of missing scores was equivalent in both groups (ORadj 0.4, p = 0.42).

CONCLUSIONS

The advantages of electronic data capture, such as real-time assessment and fewer data entry errors, may come at the price of more time required for data collection when the patients have mental health problems. As this is not uncommon in thyroid cancer, researchers need to choose the type of data capture wisely for their particular research question.

Assessment of quality of life in thyroid cancer patients using the EORTC thyroid-specific questionnaire: a prospective cross-sectional study

BACKGROUND

Many studies on the quality of life (QoL) among the thyroid cancer survivors have shown conflicting results. This may be since many of these studies have not used thyroid cancer-specific questionnaires.

PATIENTS AND METHODS

In our study we have translated the EORTC THY-34, validated and served it in a cross-sectional study to the assess the QoL among thyroid cancer patients free of disease during their routine follow-up. Patients were categorized based on the duration from treatment completion, ATA risk stratification, treatment received, number of RAI sessions and thyroid function status during analysis.

RESULTS

Overall, 220 thyroid cancer survivors were included in this study. In general, in the EORTC QLQ-C30, the global QoL of thyroid cancer patients were good with a mean score of 72.99. The highest score was that for social functioning (89.55). In the EORTC-THY34 all the patients in the cohort had relatively lower scores (on symptom scales). Overall, there was no difference in the QLQ-C30 and THY-34 QoL with respect to any of the categorization mentioned above. However, our thyroid cancer patients QoL scores were better and/or comparable to those in published literature and they were also better or comparable to the QoL of the general population those were available in literature.

CONCLUSIONS

There was no difference in the QoL scores based on various categories. To better understand the quality of life of these patients a prospective longitudinal study with baseline values and values at regular intervals might give us a better insight.

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.

Dynamic risk assessment in patients with differentiated thyroid cancer

The current approach for patients with differentiated thyroid carcinoma should be individualized according to the risk of recurrence, and this stratification could be used to identify the risk of persistent/recurrent disease in three scenarios: preoperatively, immediately postoperatively, and during long-term follow-up. The initial risk of recurrence will tailor the management of the patient in the preoperative and immediate postoperative settings, while the dynamic risk, which considers the responses to treatment, could guide the decision-making process for remnant ablation and long-term management.This review provides a summary of the existing information regarding the dynamic risk of recurrence and recommended management for patients with differentiated thyroid cancer. The application of this approach is essential to avoid unnecessary treatments for most patients who will have a favorable prognosis. On the other hand, it allows specific therapeutic interventions for those patients at high risk of recurrence. In the future, analysis of tumor biology and prospective studies will surely improve the accuracy of recurrence risk prediction.

Trajectory analysis of microwave ablation treatment effect on the quality of life and emotional distress in patients with papillary thyroid cancer

PURPOSE

Trajectory changes of quality of life (QOL) and psychological status in patients with T1N0M0 papillary thyroid cancer (PTC) after microwave ablation (MWA) treatment.

METHODS

Patients with T1N0M0 PTC who underwent MWA from March to August 2021 were included in this study. Patients completed the European Organisation for Research and Treatment of Cancer questionnaire (QLQ-C30), Thyroid Cancer-Specific Quality of Life Questionnaire (THYCA-QOL) and Hospital Anxiety and Depression Scale (HADS) at baseline, 3 months, 6 months, 9 months and 12 months after MWA.

RESULTS

181 patients were enrolled in this study. All patients met a minimum of 12 months of follow-up. The QOL at baseline and 12 months after MWA were 14.95 ± 1.78 and 14.19 ± 1.73 (P < 0.01), respectively. Patients' anxiety was 3.33 ± 1.81 and 1.49 ± 2.14 (P < 0.01), respectively. Patients' depression was 2.14 ± 2.10 and 1.40 ± 2.22 (P < 0.01), respectively. In the trajectory analysis, 73%, 19% and 8% of patients achieved significant improvement, slight improvement and stable in QOL, respectively, with older, female, lower education and lower monthly income as the risk factors of QOL. 63%, 31% and 6% of patients achieved significant improvement, slight improvement and stable in anxiety, respectively, with younger, female, lower education, lower monthly income, unmarried or divorced and higher T3, T4 levels as the risk factors of anxiety. 72%, 21% and 7% of patients achieved significant improvement, slight improvement and stable in depression, respectively, with younger, lower monthly income and unmarried or divorced as the risk factors of depression.

CONCLUSIONS

MWA can effectively improve the QOL and emotional distress of patients with T1N0M0 PTC.

Determinants and mediating mechanisms of quality of life and disease-specific symptoms among thyroid cancer patients: the design of the WaTCh study

BACKGROUND

Thyroid cancer (TC) patients are understudied but appear to be at risk for poor physical and psychosocial outcomes. Knowledge of the course and determinants of these deteriorated outcomes is lacking. Furthermore, little is known about mediating biological mechanisms.

OBJECTIVES

The WaTCh-study aims to; 1. Examine the course of physical and psychosocial outcomes. 2. Examine the association of demographic, environmental, clinical, physiological, and personality characteristics to those outcomes. In other words, who is at risk? 3. Reveal the association of mediating biological mechanisms (inflammation, kynurenine pathway) with poor physical and psychological outcomes. In other words, why is a person at risk?

DESIGN AND METHODS

Newly diagnosed TC patients from 13 Dutch hospitals will be invited. Data collection will take place before treatment, and at 6, 12 and 24 months after diagnosis. Sociodemographic and clinical information is available from the Netherlands Cancer Registry. Patients fill-out validated questionnaires at each time-point to assess quality of life, TC-specific symptoms, physical activity, anxiety, depression, health care use, and employment. Patients are asked to donate blood three times to assess inflammation and kynurenine pathway. Optionally, at each occasion, patients can use a weighing scale with bioelectrical impedance analysis (BIA) system to assess body composition; can register food intake using an online food diary; and can wear an activity tracker to assess physical activity and sleep duration/quality. Representative Dutch normative data on the studied physical and psychosocial outcomes is already available.

IMPACT

WaTCh will reveal the course of physical and psychosocial outcomes among TC patients over time and answers the question who is at risk for poor outcomes, and why. This knowledge can be used to provide personalized information, to improve screening, to develop and provide tailored treatment strategies and supportive care, to optimize outcomes, and ultimately increase the number of TC survivors that live in good health.

Health-Related Quality of Life and Thyroid Cancer-Specific Symptoms in Patients Treated for Differentiated Thyroid Cancer: A Single-Center Cross-Sectional Survey from Mainland China

Background: The incidence of differentiated thyroid cancer in Mainland China has increased rapidly in recent years, yet the number of studies focusing on health-related quality of life (HR-QOL) is still limited. Additionally, some of the quality-of-life (QOL) issues specific to thyroid cancer have not been adequately described. The aims of this study were to assess the generic and disease-specific HR-QOL of differentiated thyroid cancer survivors and to identify the associated factors. Methods: A cross-sectional survey including 373 patients was conducted in Mainland China. Participants completed the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30), the Thyroid Cancer-Specific Quality of Life Questionnaire (THYCA-QOL), and a questionnaire on patient demographics and clinical characteristics. Results: The QLQ-C30 global mean score was 73.12 (standard deviation [SD] = 11.95), while the THYCA-QOL summary mean score was 34.50 (SD = 12.68). The two QLQ-C30 functional subscales with the lowest scores were the social functioning and role functioning subscales. The five symptom subscales of the THYCA-QOL with the highest scores were the subscales regarding less interest in sex, problems with scar, psychological problems, voice problems, and sympathetic problems. Factors associated with worse global QOL on the QLQ-C30 included a shorter time since completing primary treatment (≤6 months), a history of lateral neck dissection, and a lower current thyrotropin (TSH) level (≤0.5 mIU/L). Higher cumulative activities of radioiodine (RAI; >100 mCi), gender (women), postoperative hypoparathyroidism, and a history of lateral neck dissection were associated with worse thyroid cancer-specific QOL. In contrast, higher monthly household income (>5000￥) and a history of minimally invasive thyroid surgery were associated with better thyroid cancer-specific QOL. Conclusions: Thyroid cancer patients experience multiple health-related problems and disease-specific symptoms after completing primary treatment. Patients with a duration ≤6 months from the completion of primary treatment, those with a history of lateral neck dissection, and a current TSH level ≤0.5 mIU/L may be more likely to have impaired generic QOL. More thyroid cancer-specific symptoms may be associated with higher cumulative activities of RAI, gender (women), postoperative hypoparathyroidism, a history of lateral neck dissection, lower monthly household income, and conventional surgery.

Health literacy and fatigue, anxiety, depression, and somatic symptoms in patients with differentiated thyroid carcinoma from West China: A cross-sectional study

Background and Aims

Differentiated thyroid carcinoma (DTC) patients are associated with excellent prognosis but impaired health-related quality of life (HRQOL) by initial and subsequent therapy. Health literacy plays a pivotal role in public health and medical settings, but data on its relationship with DTC patients' HRQOL are insufficient and equivocal. This study was designed to explore the relationship between health literacy and HRQOL in patients with DTC from West China areas.

Methods

A cross-sectional study with a descriptive correlational design was conducted. 126 patients with DTC were recruited between 2020 and 2021. Levels of health literacy and HRQOL (including fatigue level, anxiety/depression status, and somatoform symptoms) were assessed by questionnaires. Pearson product-moment correlation and Stepwise multiple regression were used to examined the adjusted association of health literacy with HRQOL.

Results

Health literacy and receiving DTC-related education together explained 16.2% of the variance in fatigue level. Patients who had higher health literacy, received more DTC-related education were currently employed and less fatigue. Health literacy, fatigue level and DTC-related education together explained 31.0% of the variance in anxiety and depression of DTC patients. Patients who had higher health literacy, received more DTC-related education and less fatigue level were less anxious and depressive. Age explained 8.3% of the variance in DTC patients' somatoform symptoms. Older patients complained more somatoform symptoms.

Conclusion

Health literacy was positively associated with HRQOL in DTC patients regarding to fatigue level and anxiety/depression status across the entire sample. Interventions to improve HRQOL should take the patients' health literacy into account.

Health-Related Quality of Life at Diagnosis for Pediatric Thyroid Cancer Patients

CONTEXT

Pediatric thyroid cancer (TC) incidence rates are increasing, yet TC has one of the highest survival rates. Despite increased prevalence, little is known about youth adjustment to TC, particularly compared to other pediatric cancers.

OBJECTIVE

The current study sought to describe health-related quality of life (HRQoL) in pediatric TC patients early after diagnosis compared to other pediatric cancer patients and healthy youth and examine predictors of HRQoL.

DESIGN

Patients completed psychosocial questionnaires as part of a clinic-based screening program around time of surgery. TC HRQoL was compared to other pediatric cancer and healthy youth reported norms. Clinical and demographic data extracted from the medical record were examined for predictors of HRQoL.

SETTING

Pediatric Thyroid Center.

PATIENTS AND OTHER PARTICIPANTS

Pediatric TC patients (ages 8.5-23.4 years) and their caregivers.

MAIN OUTCOME MEASURES

Pediatric Quality of Life Inventory (HRQoL) and distress thermometer.

RESULTS

Findings evidenced significantly higher HRQoL for TC patients than other pediatric cancers for all but emotional and school functioning. Compared to healthy youth, TC patients reported significantly lower functioning, except comparable social functioning. No significant differences in HRQoL were identified based on disease severity, thyroid disease history, or treatment. Patient distress was associated with HRQoL.

CONCLUSIONS

The findings suggest general resilience in TC patients compared to youth with other cancers, yet worse HRQoL than peers. Early universal screening is warranted due to a short TC treatment regimen. If administrative barriers preclude comprehensive screening, the single-item distress thermometer may identify patients for further comprehensive screening.

Quality of Life and Surgical Outcome of Transoral Endoscopic Thyroidectomy Vestibular Approach (TOETVA) versus Open Thyroid Surgery: Experience from a Single Center in Vietnam

Background

It has been widely assumed that TOETVA has demonstrated a new technique and a promising approach as it is both minimally invasive and optimally cosmetic. The objective of this study was to assess the surgical outcome, aesthetic satisfaction, and postoperative quality of life of TOETVA in comparison with open thyroid surgery. Patients and Methods. The study was designed as a prospective study, in which 121 patients from a single center in Vietnam underwent thyroid surgery, and the study was divided into two groups: 60 patients in the TOETVA group and 61 patients in the open surgery group. The patients have been followed up including surgical outcomes, cosmetic satisfaction, and quality of life. These criteria were assessed at 4 weeks, 8 weeks, and 12 weeks after the surgery using SF-36 and thyroid surgery-specific questionnaire.

Results

Patients in the TOETVA group are significantly younger than patients in the open surgery group (35.8 + 10.3 vs 46.9 + 11.5, p < 0.001). The mean operating time was longer in the TOETVA group (102.9 ± 26.1 mins) than that in the open surgery group (66.8 ± 23.8 mins) with p = 0.0001. Cosmetic outcomes and overall satisfaction were significantly greater in the TOETVA group p = 0.0001. The SF-36 QOL scores of the patients in the TOETVA group were generally higher than the open surgery group.

Conclusions

TOETVA has been widely used with a low complication rate, cosmetic appeal, and surgical efficacy. Postoperative quality of life, cosmetic outcomes, and overall satisfaction were significantly superior to the open surgery group.

Predictors of Anxiety and Depression in Differentiated Thyroid Cancer Survivors: Results of a Cross-Sectional Study

Background: Despite an excellent survival rate, impairments are recognized in the quality of life and emotional well-being of differentiated thyroid cancer (DTC) survivors. Predictors for anxiety and depression in DTC patients are not well characterized. Objective: To identify predictors for anxiety and depression in DTC survivors. Methods: In this cross-sectional study, all DTC survivors presenting for follow-up between 2014 and 2019 in a tertiary referral hospital were asked to complete the "Hospital Anxiety and Depression Scale" (HADS). Depression (HADS-D) and anxiety (HADS-A) subscores were dichotomized for analysis. Univariate and multivariable logistic regression analyses were performed to identify predictors of anxiety and depression. Inverse probability weighting was applied to correct for bias due to nonresponse. Results: Six hundred forty patients meeting study inclusion criteria completed the HADS questionnaire (73% female, mean age 50 years). Of these, 37.6% and 15.7% of patients demonstrated HADS-A and HADS-D scores ≥8. Female sex, elevated body mass index (BMI), permanent recurrent laryngeal nerve damage (RLND), permanent hypoparathyroidism (PH), comorbidities classified in chapter XIX of the International Classification of Diseases, 10th Revision (ICD-10; external causes of morbidity and mortality), and comorbidities in chapter XXI of ICD-10 (factors influencing health status and contact with health services) were independent predictors for elevated anxiety scores with adjusted odds ratios of 1.9 ([CI 1.2-3.2], p < 0.01), 1.0 ([CI 1.0-1.1], p = 0.02), 2.6 ([CI 1.0-6.3], p = 0.04), 2.0 ([CI 1.1-3.5], p = 0.02), 5.5 ([CI 1.0-29.6], p < 0.05), and 1.7 ([CI 1.1-2.6], p = 0.03). PH, elevated anti-Tg titer, comorbidities of the digestive system (chapter XI of ICD-10), and comorbidities of the genitourinary system (chapter XIV of ICD-10) were independent predictors for depression with adjusted odds ratios of 2.2 ([CI 1.2-4.2], p = 0.01), 1.0 ([CI 1.0-1.0], p = 0.04), 3.0 ([CI 1.5-6.1], p < 0.01), and 2.4 ([CI 1.0-5.7], p = 0.04). Conclusions: Female sex, elevated BMI, RLND, PH, and comorbidities classified in chapter XIX and chapter XXI of ICD-10 are predictors for anxiety in DTC patients. PH, elevated anti-Tg titer, comorbidities of the digestive system, and comorbidities of the genitourinary system are predictors for depression in DTC patients. Physicians involved in the follow-up of DTC patients should devote particular attention to the emotional well-being in DTC patients with PH or permanent RLND.

Saliva microbiome changes in thyroid cancer and thyroid nodules patients

Objective

Thyroid disease has been reported to associate with gut microbiota, but the effects of thyroid cancer and thyroid nodules on the oral microbiota are still largely unknown. This study aimed to identify the variation in salivary microbiota and their potential association with thyroid cancer and thyroid nodules.

Methods

We used 16S rRNA high-throughput sequencing to examine the salivary microbiota of thyroid cancer patients (n = 14), thyroid nodules patients (n = 9), and healthy controls (n = 15).

Results

The alpha-diversity indices Chao1 and ACE were found to be relatively higher in patients with thyroid cancer and thyroid nodules compared to healthy controls. The beta diversity in both the thyroid cancer and thyroid nodules groups was divergent from the healthy control group. The genera Alloprevotella, Anaeroglobus, Acinetobacter, unclassified Bacteroidales, and unclassified Cyanobacteriales were significantly enriched in the thyroid cancer group compared with the healthy control group. In contrast, the microbiome of the healthy controls was mainly composed of the genera Haemophilus, Lautropia, Allorhizobium Neorhizobium Pararhizobium Rhizobium, Escherichia Shigella, and unclassified Rhodobacteraceae. The thyroid nodules group was dominated by genre uncultured Candidatus Saccharibacteria bacterium, unclassified Clostridiales bacterium feline oral taxon 148, Treponema, unclassified Prevotellaceae, Mobiluncus, and Acholeplasma. In contrast, the genera unclassified Rhodobacteraceae and Aggregatibacter dominated the healthy control group. The study also found that clinical indicators were correlated with the saliva microbiome.

Conclusion

The salivary microbiota variation may be connected with thyroid cancer and thyroid nodules.

Quality of Life of Survivors of Thyroid Cancer Is Not Inferior to That in Subjects without Cancer: Long-Term after Over 5 Years

BACKGRUOUND

Patients with thyroid cancer undergo less extensive surgery and additional therapies compared to those with other cancers. We aimed to compare the quality of life (QoL) between patients with thyroid cancer and healthy subjects using representative data from Korea. Differences in QoL of thyroid cancer survivors according to the duration after cancer diagnosis was also evaluated.

METHODS

This population-based cohort study included 50,278 subjects who participated in the Korea National Health and Nutrition Examination Survey between 2007 and 2017. QoL was compared between patients with thyroid cancer and healthy subjects using self-reported data from the EuroQoL (EQ)-5 dimension (5D) and EQ-visual analog scale (VAS). Propensity score matching was used to match thyroid cancer survivors to healthy subjects (1:5 matching).

RESULTS

Linear regression with univariate analysis showed that the presence of thyroid cancer was positively correlated with better EQ-5D index scores (β-coefficient=0.010, p=0.046). After adjusting for multiple covariables, statistical significance was maintained. EQ-VAS fails to demonstrate any significant correlation. Among the EQ-5D categories, patients with thyroid cancer showed better self-care than healthy subjects. Thyroid cancer duration did not correlate with the EQ-5D index score. In subgroup analyses, compared to patients with thyroid cancer duration of <5 years, no significant difference was observed in the correlation between the EQ-5D index score and survival duration in those with thyroid cancer duration of 5 to 9 years and ≥10 years.

CONCLUSION

Using a large-scale nationwide population-based database, our study demonstrated better QoL, especially in terms of self-care, among thyroid cancer survivors than among healthy subjects without cancer.

Cabozantinib for the treatment of solid tumors: a systematic review

Background:

Cabozantinib is approved, in various settings, for the treatment of renal cell carcinoma, medullary thyroid cancer, and hepatocellular carcinoma, and it has been investigated for the treatment of other cancers. With the available evidence and the real-world performance of cabozantinib compared with clinical trial data, we performed a systematic review of cabozantinib monotherapy as treatment for solid tumors in adults.

Methods:

This study was designed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses and registered with PROSPERO (CRD42020144680). We searched for clinical and observational studies of cabozantinib monotherapy for solid tumors using Embase, MEDLINE, and Cochrane databases (October 2020), and screened relevant congress abstracts. Eligible studies reported clinical or safety outcomes, or biomarker data. Small studies (n < 25) and studies of cabozantinib combination therapies were excluded. Quality was assessed using National Institute for Health and Care Excellence methodology, and study characteristics were described qualitatively.

Results:

Of 2888 citations, 114 were included (52 randomized studies, 29 observational studies, 32 nonrandomized phase I or II studies or pilot trials, and 1 analysis of data from a randomized study and a nonrandomized study). Beyond approved indications, other tumors studied were castration-resistant prostate cancer, urothelial carcinoma, Ewing sarcoma, osteosarcoma, uveal melanoma, non-small-cell lung cancer, Merkel cell carcinoma, glioblastoma, pheochromocytomas and paragangliomas, cholangiocarcinoma, gastrointestinal stromal tumor, colorectal cancer, salivary gland cancer, carcinoid and pancreatic neuroendocrine tumors, and breast, endometrial and ovarian cancers. The most common adverse events were hypertension, diarrhea, and fatigue.

Conclusion:

The identified evidence demonstrates the positive efficacy/effectiveness of cabozantinib monotherapy in various solid tumor types, with safety findings being consistent with those observed with other VEGFR-targeting tyrosine kinase inhibitors. When available, real-world findings were consistent with the data reported from clinical trials. A limitation of this review is the high proportion of abstracts; however, this allowed us to capture the most up-to-date findings.

Health-Related Quality of Life following Total Thyroidectomy and Lobectomy for Differentiated Thyroid Carcinoma: A Systematic Review

Health-related quality of life (HrQoL) is a major concern for patients with differentiated thyroid carcinoma (DTC). We aimed to systematically review the literature comparing HrQol following total thyroidectomy (TT) and hemithyroidectomy (HT) in DTC patients. A systematic review of publications indexed in Medline, Embase, and EBM reviews—Cochrane Central Register of Controlled Trials, which evaluated HrQoL following thyroid surgery for DTC, was conducted. Of 2507 identified records, 25 fulfilled the inclusion criteria. Our results suggest that patients undergoing TT may suffer more impairment in physical and social HrQoL than patients undergoing HT. Psychological-related HrQoL and long-term global HrQoL are, however, equivalent in both groups, which highlights the multidimensional nature of HrQoL and the importance of a multitude of factors aside from treatment modalities and related morbidities, such as the experience of receiving a cancer diagnosis, the fear of cancer recurrence, and other psychosocial factors. Addressing postoperative HrQoL when discussing therapeutic options with patients is an integral part of patient-centered care and informed shared decision-making, and should be approached in a holistic manner, accounting for its physical, psychological, and social aspects. This review supplies evidence regarding HrQoL following thyroid surgery, which can be employed in such decisions.

Sleep quality, stress and thyroid cancer: a case-control study

BACKGROUND

Stress and sleep disturbance have been found to be associated with numerous adverse health outcomes, including cancer. Our study aimed to measure the association between quality of sleep, short-temperedness, and stress in life with the risk of thyroid cancer.

METHODS

The present study is conducted on 361 newly diagnosed TC patients and 347 sex-age frequency matched controls. Control and case participants were registered with the same health centers. We used multiple logistic regression to investigate the association between TC risk and the interested factors.

RESULTS

Based on the results of the multivariate analysis, stress (OR_{always stressful/often calm} = 3.07, 95% CI 1.42-6.63) and short-temperedness (OR_nervous/calm = 2.00, 95% CI 1.28-3.11) were directly associated with the risk of TC. On the other hand having a quality sleep (OR_{sometimes/never} = 0.36, 95% CI 0.16-0.79) and quality sleep (OR_often/no = 0.45, 95% CI 0.21-0.96, P = 0.041) seems to be a protective factor.

CONCLUSIONS

Some community-based interventions, e.g., lowering stress levels and improving sleep quality, may help in preventing different types of cancer, including TC. We suggest further evaluation of these important findings in the prevention of TC cancer.

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.

A practical nutritional guideline to manage neuroendocrine neoplasms through chronotype and sleep

Chronotype is the attitude of subjects to carry out their daily activities mainly in the morning ("lark") or in the evening ("owl"). The intermediate chronotype is located between these two categories. It has been demonstrated that chronotype can influence the incidence, course and response to treatments of tumors. In particular patients diagnosed with gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) and evening chronotype are characterized by unhealthy lifestyle, obesity, metabolic syndrome, a worsen cardiometabolic profile, a poor prognosis with a progressive disease and the development of metastasis. In addition, evening chronotype has been associated with sleep disturbances, which in turn have been related to tumor development and progression of tumors. There is a strict connection between sleep disturbances and NENs because of the hyperactivation of proangiogenic factors that caused aberrant neoangiogenesis. A nutritional tailored approach could represent a tool to align subjects with evening chronotype to physiological biological rhythms based on the properties of some macro and micronutrients of being substrate for melatonin synthesis. Thus, we aimed to provide an overview on the association of chronotype categories and sleep disturbances with NENs and to provide nutritional advices to manage subjects with NENs and these disturbances of circadian rhythm.

Distress, anxiety, depression and unmet needs in thyroid cancer survivors: a longitudinal study

PURPOSE

Despite a good prognosis, thyroid cancer (TC) survivors often report psychological distress and decreased quality of life. This longitudinal study aims to evaluate TC survivors' levels of distress, anxiety, depression and unmet needs, checking potential life events.

METHODS

Distress Thermometer, Hospital Anxiety Depression Scale, Supportive Care Need Survey (short form) and Interview for Recent Life Events were administered to 73 TC survivors (T0) and 44 of them were re-tested one year later (T1). Participants were at 0-5, 5-10 or >10 years from the end of their cancer-related treatments.

RESULTS

At T0, distress, anxiety and depression mean scores were 6.4, 6.8 and 5.3, while at T1 they were 5.5, 4.8 and 5.1. Only anxiety scores decreased significantly between T0 and T1. 50.7% of patients had unmet psychological needs at T0 and 50.0% at T1. Most participants were satisfied in the communicative/ informative (T0:79.5%; T1: 77.3%) and social/health care areas (T0:74.0%; T1:75.0%). The most experienced stressful events detected concerned their working areas.

CONCLUSIONS

Results confirmed that patients reported distress, anxiety and depression concerns even many years after the end of treatments. Both medical and psychological surveillance are relevant to improving TC survivors' wellbeing.

Machine learning-based random forest for predicting decreased quality of life in thyroid cancer patients after thyroidectomy

OBJECTIVE

Decreased quality of life (QoL) in thyroid cancer patients after thyroidectomy is a common, but there is a lack of predictive methods for decreased QoL. This study aimed to construct a machine learning-based random forest for predicting decreased QoL in thyroid cancer patients 3 months after thyroidectomy.

MATERIALS AND METHODS

Two hundred and eighty-six thyroid cancer patients after thyroidectomy were enrolled in this prospective cross-sectional study from November 2018 to June 2019, and were randomly assigned to training and validation cohorts at a ratio of 7:3. The European Organization for Research and Treatment of Cancer quality of life questionnaire version 3 (EORTC QLQ-C30) questionnaire was used to assess the QoL 3 months after thyroidectomy, and decreased QoL was defined as EORTC QLQ-C30 < 60 points. The random forest model was constructed for predicting decreased QoL in thyroid cancer patients after thyroidectomy.

RESULTS

The mean QoL 3 months after thyroidectomy was 65.93 ± 9.00 with 21.33% (61/286) decreased QoL. The main manifestation is fatigue in symptom scales and social functioning dysfunction in functional scales. The top seven most important indices affecting QoL were clinical stage, marital status, histological type, age, nerve injury symptom, economic income and surgery type. For random forest prediction model, the areas under the curve in the training and validation courts were 0.834 and 0.897, respectively.

CONCLUSION

The present study demonstrated that random forest model for predicting decreased QoL in thyroid cancer patients 3 months after thyroidectomy displayed relatively high accuracy. These findings should be applied clinically to optimise health care.

Cost-Effectiveness of Follow-up Ultrasound for Incidental Thyroid Nodules on CT

Background: Thyroid nodules are common incidental findings on CT. Existing professional society recommendations, based primarily on expert opinion, advise follow-up ultrasound for nodules above size cut-offs in patients of all ages. Purpose: To evaluate the cost-effectiveness of current recommendations as well as of other age- and size-based follow-up strategies for thyroid nodules incidentally detected on CT, using a simulation model. Methods: By using a simulation model with 1,000,000 adult patients with nodules measuring ≤40 mm and having no suspicious features, we evaluated size cut-offs from 5 to 25 mm under an age maximum from 25 to 65 years, as well as follow-up versus no follow-up above the age maximum. For each strategy, patient survival was determined by disease-specific and baseline mortality rates, as well as surgical mortality. Costs and quality-adjusted life years (QALYs) were tabulated. A probabilistic sensitivity analysis was performed varying model parameters. Results: All cost-effective strategies recommended no follow-up for patients above the age cut-offs (which varied from 25 to 65 years). In the base case simulation, 8 strategies were cost-effective under a willingness-to-pay threshold of $100,000/QALY. Of these, the strategy yielding the highest QALYs was follow-up for patients <60 years old with nodules ≥10 mm and no follow-up for patients ≥60 years old, with an incremental cost-effectiveness ratio of $50,196/QALY (95% CI $39,233 - $67,479). In the probabilistic sensitivity analysis, if the 10-year disease-specific survival of untreated cancer was >94% of patients with treated cancer, then no follow-up for any nodules was optimal. Conclusion: Follow-up ultrasound for thyroid nodules incidentally detected on CT is likely not cost-effective in older patients. Follow-up for most thyroid nodules in younger patients may be cost-effective. Clinical Impact: Future societal recommendations may account for the limited benefit of obtaining follow-up for incidental thyroid nodules on CT in older patients.

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.

Impact of Permanent Post-thyroidectomy Hypoparathyroidism on Self-evaluation of Quality of Life and Voice: Results from the National QoL-hypopara Study

OBJECTIVE

To compare the quality of life (mental health) and voice in patients with or without permanent hypoparathyroidism after total thyroidectomy.

SUMMARY BACKGROUND DATA

Permanent hypoparathyroidism is an underestimated complication of thyroid surgery owing to suppression of parathormone secretion. Few studies have evaluated the consequences of hypoparathyroidism on quality of life and none has studied its effects on voice.

METHODS

The QoL-hypopara study (ClinicalTrial.gov NCT04053647) was a national observational study. Adult thyroidectomized patients were included between January and June 2020. A Serum parathormone level <15pg/mL more than 6 months after surgery defined permanent hypoparathyroidism. Patients answered the MOS-36-item short-form health (SF-36), the Voice Handicap Index (VHI) surveys, and a list of questions regarding their symptoms.

RESULTS

141 patients were included, 45 with permanent hypoparathyroidism. The median period between thyroid surgery and the questionnaire was 6 [Q1-Q3 4-11] and 4 [4-5] years in hypoparathyroid patients and controls respectively. Hypoparathyroid patients presented a reduced median mental score ratio (SF-36) (0.88 [Q1-Q3 0.63-1.01] versus 1.04 [0.82-1.13], P=0.003) and a lower voice quality (incidence rate ratio for total VHI 1.83-fold higher, P<0.001). In multivariable analysis, hypoparathyroidism (-0.17 [95%CI -0.28--0.07], P=0.002), but not age, female sex, thyroid cancer, or abnormal TSH level, was associated with the reduced mental score ratio. Myalgia, joint pain, paresthesia, tetany, anxiety attack and exhaustion were the most common symptoms among hypoparathyroid patients (>50%).

CONCLUSIONS

Hypoparathyroid patients present significantly impaired quality of life, lower voice quality and frequent symptoms. These results reinforce the importance of preventing this complication.

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.

Health-Related Quality of Life in Asian Differentiated Thyroid Cancer Survivors

Background:

Health-related quality of life (HRQoL) is important for differentiated thyroid cancer survivors, but data for Asian survivors is lacking. This study aimed to have an overview of, and identify any disease-or treatment-related factors associated with, HRQoL in Asian differentiated thyroid cancer survivors.

Patients and Methods:

Thyroid cancer survivors were recruited from the thyroid clinics at Queen Mary Hospital, Hong Kong from February 2016 to December 2016. All adult differentiated thyroid cancer patients with stable disease more than or equal to 1 year received a survey on HRQoL using the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and Thyroid cancer specific quality of life (THYCA-QoL) questionnaire. Clinical information was collected retrospectively from the computerized clinical management system. To identify factors associated with poor HRQoL, univariable and stepwise multivariable regression analysis were performed.

Results:

A total of 613 survivors completed the questionnaires (response rate: 82.1%; female: 80.1%; median survivorship: 7.4 years (range: 1.0-48.2 years)). The QLQ-C30 summary score mean was 84.4 (standard deviation (SD): 12.7) while the THYCA-QoL summary score mean was 39.9 (SD: 9.7). The 2 highest symptom subscales were fatigue (mean: 26.4, SD: 20.6) and insomnia (mean: 26.2, SD: 27.6). Factors associated with worse HRQoL included serum thyrotropin (TSH) greater than 1.0 mIU/L, unemployment, and concomitant psychiatric disorders. Concomitant psychiatric illness (n = 40/613, 6.5%) also showed significant association with most of the symptom and functional subscales.

Conclusions:

Fatigue and insomnia were the 2 most common symptoms experienced by our differentiated thyroid cancer survivors. Long-term survivorship care with monitoring serum TSH level, supporting return-to-work and screening for concomitant psychiatric disorders should be offered.

[Cross-cultural adaptation of the French version of the thyroid cancer-specific quality of life questionnaire: THYCA-QoL]

INTRODUCTION

The aim of this study was to translate into French the 24 items of the THYCA-QoL questionnaire used in thyroid cancers and then to study its psychometric properties.

MATERIALS AND METHODS

The THYCA-QoL is a specific questionnaire for evaluating the quality of life of patients undergoing thyroid cancer surgery. It consists of 24 items and is divided into seven dimensions and six isolated questions. The translation has been carried out according to the recommendations of the EORTC. Validation of the translated version was obtained by finding a consensus of experts for each of the items.

RESULTS

All the original questions of the questionnaire have been adapted into French. The translated questionnaire, named THYCA-CoL-fr, was tested on 60 patients (65 % female), mean age 54.5 years. All questions were well accepted and understood and no missing data were reported. Eight patients (13 %) proposed an item correction to the questionnaire. No attenuation effects (floor or ceiling) were detected. The internal structure was comparable to the original questionnaire: Cronbach α coefficients varied from 0.53 for the oropharyngeal dimension to 0.88 for the voice dimension. The scree-plot highlighted the seven dimensions of the English version.

CONCLUSION

THYCA-QoL-fr is the first specific French language questionnaire to evaluate the quality of life in thyroid cancer patients undergoing surgery. These first exploratory psychometric results confirmed the conceptual similarity of the French translation and the English version.

Patient Reported Outcome Measures of Health-Related Quality of Life and Asthenia after Thyroidectomy

BACKGROUND

After thyroidectomy some patients experience a chronic fatigue syndrome called asthenia. The purpose of this study was to determine the post-operative health related quality of life (HRQOL) and risk of asthenia in patients undergoing thyroidectomy.

METHODS

A single institution prospective observational cohort study of adults undergoing thyroidectomy from September 2016 to July 2019 with four HRQOL surveys: preoperative baseline, 2 wk-, 6 mo- and 12 mo-postoperatively. Patients were surveyed using the Short Form 36 version 2 and Brief Fatigue Inventory. Asthenia was defined as Brief Fatigue Inventory > 60 at 12 mo. HRQOL was compared between patients undergoing thyroid lobectomy (TL) or total thyroidectomy (TT) with benign (-B) or malignant (-Ca) final pathology.

RESULTS

A total of 182 patients were included: 67 (37%) with TL-B, 32 (17%) with TL-Ca, 40 (22%) with TT-B, and 43 (24%) with TT-Ca. The incidence of asthenia was 42% for TT and 4% for TL. In the TL-B group, 2 patients (3%) developed asthenia, compared with 2 patients (6.25%) in the TL-Ca group, 14 patients (35%) in the TT-B group, and 21 (48.8%) in the TT-Ca group (P = 0.0001). The odds ratio of asthenia for TT compared to TL was 10.4 (95% CI 3.86-28.16) and for patients with malignancy compared to benign disease was 2.05 (95% CI 1.17-3.61).

CONCLUSIONS

Patients undergoing TT have a higher risk of developing asthenia than those undergoing TL, particularly if the final pathology shows malignancy.

Patients' Reaction to Diagnosis with Thyroid Cancer or an Indeterminate Thyroid Nodule

Introduction: Little is known about the experiences and concerns of patients recently diagnosed with thyroid cancer or an indeterminate thyroid nodule. This study sought to explore patients' reactions to diagnosis with papillary thyroid cancer (PTC) or indeterminate cytology on fine needle aspiration. Methods: We conducted semistructured interviews with 85 patients with recently diagnosed PTC or an indeterminate thyroid nodule before undergoing thyroidectomy. We included adults with nodules ≥1 cm and Bethesda III, IV, V, and VI cytology. The analysis utilized grounded theory methodology to create a conceptual model of patient reactions. Results: After diagnosis, participants experienced shock, anxiety, fear, and a strong need to "get it out" because "it's cancer!" This response was frequently followed by a sense of urgency to "get it done," which made waiting for surgery difficult. These reactions occurred regardless of whether participants had confirmed PTC or indeterminate cytology. Participants described the wait between diagnosis and surgery as difficult, because the cancer or nodule was "still sitting there" and "could be spreading." Participants often viewed surgery and getting the cancer out as a "fix" that would resolve their fears and worries, returning them to normalcy. The need to "get it out" also led some participants to minimize the risk of complications or adverse outcomes. Education about the slow-growing nature of PTC reassured some, but not all patients. Conclusions: After diagnosis with PTC or an indeterminate thyroid nodule, many patients have strong emotional reactions and an impulse to "get it out" elicited by the word "cancer." This reaction can persist even after receiving education about the excellent prognosis. Understanding patients' response to diagnosis is critical, because their emotional reactions likely pose a barrier to implementing guidelines recommending less extensive management for PTC.

Effect of Initial Treatment Choice on 2-year Quality of Life in Patients with Low-risk Papillary Thyroid Microcarcinoma

CONTEXT

The long-term quality of life (QoL) in patients with low-risk papillary thyroid microcarcinoma (PTMC) underwent active surveillance (AS) and immediate surgery is unclear.

OBJECTIVE

The aim of this study was to investigate the effect of initial treatment choice on 2-year QoL in patients with low-risk PTMC.

DESIGN, SETTING, AND PARTICIPANTS

We analyzed 2652 QoL surveys from 1055 subjects enrolled in ongoing multicenter prospective cohort study on active surveillance of PTMC, in which the median follow-up duration was 24.4 months.

MAJOR OUTCOME MEASURE

We evaluated QoL of patients with low-risk PTMC according to their treatment modality using generalized estimating equation.

RESULTS

Six hundred and seventy-four subjects (male = 161; mean age = 48.8 ± 11.9 years) with low-risk PTMC chose AS while 381 subjects (male = 75; mean age = 45.7 ± 10.4 years) chose immediate surgery, including lobectomy/isthmusectomy (L/I) and total thyroidectomy (TT). Among the 817 subjects who completed baseline QoL surveys, 2-year QoL was good in order of AS (n = 500), L/I (n = 238), and TT (n = 79) groups after adjustment for age, sex, baseline tumor size, and baseline QoL scores. Among the 101 subjects who changed their treatment from AS to surgery during the follow-up period, 35 subjects who changed treatment due to disease progression had better QoL than 66 subjects who had no disease progression.

CONCLUSIONS

This study identified QoL as a major issue in choosing an initial treatment of low-risk PTMC and highlighted the possibility of using AS as the primary treatment.

Thyroid cancer patients satisfaction at the management outcome: an analysis of the results of a nationwide survey in 485 subjects

BACKGROUND

We aimed to measure satisfaction of patients with thyroid cancer concerning different aspects of healthcare.

METHODS

We developed a web-based survey. Questions focused on patient satisfaction with specialists, the health centers and departments, and the information received about their disease. Level of satisfaction was quantified using a scale of 1 to 5. Values ≥4 were considered a high degree of satisfaction.

RESULTS

Four hundred eighty-five patients (aged 43.4 ± 9.9 yrs., 88% females) completed the survey. A high overall satisfaction with the specialists was reported by 52.5% of patients. The most highly valued specialists were surgeons, oncologists, and endocrinologists. 56.5% of respondents reported a high overall satisfaction with the health centers and departments. Lastly, the proportion of patients who were highly satisfied with the information received was only 42.5%. The presence of complications was indirectly related with satisfaction with specialists and information. Satisfaction with health centers and services was directly related with the level of education and inversely related to the time of evolution of the disease.

CONCLUSION

Our results show a high degree of overall satisfaction of thyroid cancer patients. However, satisfaction can be improved in some areas, such with regards to the information provided to patients.

Lessons learned from Chernobyl and Fukushima on thyroid cancer screening and recommendations in case of a future nuclear accident

Exposure of the thyroid gland to ionizing radiation at a young age is the main recognized risk factor for differentiated thyroid cancer. After the Chernobyl and Fukushima nuclear accidents, thyroid cancer screening was implemented mainly for children, leading to case over-diagnosis as seen in South Korea after the implementation of opportunistic screening (where subjects are recruited at healthcare sites). The aim of cancer screening is to reduce morbidity and mortality, but screening can also cause negative effects on health (with unnecessary treatment if over-diagnosis) and on quality of life. This paper from the SHAMISEN special issue (Nuclear Emergency Situations - Improvement of Medical And Health Surveillance) presents the principles of cancer screening, the lessons learned from thyroid cancer screening, as well as the knowledge on thyroid cancer incidence after exposure to iodine-131. The SHAMISEN Consortium recommends to envisage systematic health screening after a nuclear accident, only when appropriately justified, i.e. ensuring that screening will do more good than harm. Based on the experience of the Fukushima screening, the consortium does not recommend mass or population-based thyroid cancer screening, as the negative psychological and physical effects are likely to outweigh any possible benefit in affected populations; thyroid health monitoring should however be made available to persons who request it (regardless of whether they are at increased risk or not), accompanied with appropriate information and support.

A systematic review of health state utility values for thyroid cancer

Purpose

Health state utility values are commonly used to inform economic evaluations and determine the cost-effectiveness of an intervention. The aim of this systematic review is to summarise the utility values available to represent the health-related quality of life (HRQoL) of patients with thyroid cancer.

Methods

Eight electronic databases were searched from January 1999 to April 2019 for studies which included assessment of HRQoL for patients with thyroid cancer. Utility estimates derived from multiple sources (EuroQol questionnaire 5-dimension (EQ-5D), time trade-off [TTO] and standard gamble [SG] methods) were extracted. In addition, utility estimates were generated by mapping from SF-36 and EORTC QLQ-30 to the EQ-5D-3L UK value set using published mapping algorithms.

Results

Searches identified 33 eligible studies. Twenty-six studies reported HRQoL for patients with differentiated thyroid cancer and seven studies for patients with general thyroid cancer. We identified studies which used different methods and tools to quantify the HRQoL in patients with thyroid cancer, such as the EQ-5D-3L, SF-36, EORTC QLQ-30 and SG and TTO techniques to estimate utility values. Utility estimates range from 0.205 (patients with low-risk differentiated thyroid cancer) to utility values approximate to the average UK population (following successful thyroidectomy surgery and radioiodine treatment). Utility estimates for different health states, across thyroid cancer sub-types and interventions are presented.

Conclusion

A catalogue of utility values is provided for use when carrying out economic modelling of thyroid cancer; by including mapped values, this approach broadens the scope of health states that can be considered within cost-effectiveness modelling.

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

BACKGROUND

Patients with malignancy suffer impairment of their quality of life (QoL). QoL has been evaluated in thyroid cancer patients. Since 2010, a new inventory, the thyroid-specific patient-reported outcome (ThyPRO) measure for benign thyroid disorders, has been available.

AIM

This study evaluated QoL longitudinally in patients with a history of differentiated thyroid cancer (DTC) by means of the ThyPRO questionnaire. Methods : From 2012 to 2016, QoL was evaluated yearly in 123 adult DTC patients by means of ThyPRO. The ThyPRO questionnaire consists of 13 scales on which higher scores represent greater impact on QoL in areas affected by thyroid pathology. Disease-specific morbidity due to possible inadequate L-T4 treatment was evaluated by means of the Billewicz scale (BS). The same examinations were conducted in 192 control subjects who had undergone surgery for benign thyroid pathology.

RESULTS

DTC and control subjects had similar scores on all but one scale; scores on the hyperthyroid symptoms scale were significantly higher in DTC patients than in controls. Over the 5 years, scores did not change significantly in the DTC group. Overall, QoL and BS scores showed a slight, but not significant, improvement during the study period in DTC patients. BMI impacted on several ThyPRO scales. No significant differences between genders were noted in DTC.

CONCLUSIONS

The ThyPRO questionnaire indicates that illness perception is similar after thyroidectomy for malign and benign pathology. Only a marginal improvement in QoL was noted in DTC subjects over the 5-year study period. In both groups, females showed a greater perception of illness than males.

Patient Report of Recurrent and Persistent Thyroid Cancer

Background: Despite the excellent survival of most patients with differentiated thyroid cancer (DTC), recurrent and persistent disease remain major concerns for physicians and patients. However, studies on patient report of recurrent and persistent disease are lacking. Methods: Between February 1, 2017, and October 31, 2018, we surveyed eligible patients who were diagnosed with DTC between 2014 and 2015 from the Georgia and Los Angeles Surveillance, Epidemiology, and End Results cancer registries (N = 2632; response rate, 63%). Patients who reported current disease status were included in this study (n = 2454). Patient-reported data were linked to registry data. A multivariable, multinomial logistic regression analysis was conducted to determine patient and tumor characteristics associated with recurrent and persistent thyroid cancer. Quality of life was evaluated using the Patient-Reported Outcomes Measurement Information System-Global Health v1.2 questionnaire. Meaningful change in global health was defined as a minimal difference of a half standard deviation or 5 points compared with the mean (T score = 50) of a sample population matching the United States 2000 General Census. Results: Of the 2454 patients completing the survey, 95 (4.1%) reported recurrent disease and 137 (5.8%) reported persistent disease. In multinomial analyses, T3/T4 classification and cervical lymph node involvement (N1) were associated with both report of recurrent (adjusted relative risk ratio [RRR] 1.99, 95% confidence interval [CI 1.16-3.42]; adjusted RRR 2.03 [CI 1.29-3.21], respectively) and persistent disease (adjusted RRR 3.48 [CI 1.96-6.20]; adjusted RRR 3.56 [CI 2.41-5.24], respectively). Additionally, Hispanic ethnicity was associated with report of recurrent disease (adjusted RRR 1.99 [CI 1.23-3.24]). Regarding quality of life, the median scores in patients with persistent disease met criteria for meaningful change in global physical health (T-score = 44.9) and global mental health (T-score = 43.5) when compared with the general population norms. Median scores in patients with cured or recurrent disease did not meet criteria for meaningful change. Conclusions: Patient report is a reasonable method of assessing recurrent and persistent disease. Impact on quality of life is more marked for patients with reported persistent disease. Our findings will help personalize treatment and long-term follow-up in these patients.

Influence of Care Pathway on Thyroid Nodule Surgery Relevance: A Historical Cohort Study

Background: Guidelines recommend using fine-needle aspiration cytology (FNAC) to guide thyroid nodule surgical indication. However, the extent to which these guidelines are followed remains unclear. This study aimed to analyze the quality of the preoperative care pathway and to evaluate whether compliance with the recommended care pathway influenced the relevance of surgical indications. Methods: Nationwide historical cohort study based on data from a sample (1/97th) of French health insurance beneficiaries. Evaluation of the care pathway of adult patients operated on between 2012 and 2015 during the year preceding thyroid nodule surgery. The pathway containing only FNAC was called “FNAC”, the pathway including an endocrinology consultation (ENDO) with FNAC was called “FNAC+ENDO”, whereas the no FNAC pathway was called “NO FNAC”. The main outcome was the malignant nature of the nodule. Results: Among the 1080 patients included in the study, “FNAC+ENDO” was found in 197 (18.2%), “FNAC” in 207 (19.2%), and “NO FNAC” in 676 (62.6%) patients. Cancer diagnosis was recorded in 72 (36.5%) “FNAC+ENDO” patients and 66 (31.9%) “FNAC” patients, against 119 (17.6%) “NO FNAC” patients. As compared to “NO FNAC”, the “FNAC+ENDO” care pathway was associated with thyroid cancer diagnosis (OR 2.67, 1.88–3.81), as was “FNAC” (OR 2.09, 1.46–2.98). Surgeries performed in university hospitals were also associated with thyroid cancer diagnosis (OR 1.61, 1.19–2.17). Increasing the year for surgery was associated with optimal care pathway (2015 vs. 2012, OR 1.52, 1.06–2.18). Conclusions: The recommended care pathway was associated with more relevant surgical indications. While clinical guidelines were insufficiently followed, compliance improved over the years.

The effect of iatrogenic subclinical hyperthyroidism on anxiety, depression and quality of life in differentiated thyroid carcinoma

Background/aim

Overt thyroidism is known to cause neuropsychiatric disorders but studies on subclinical hyperthyroidism (SCH) are limited. Subclinical hyperthyroidism induction by administering L-Thyroxine (LT4) is the standard treatment method in differentiated thyroid carcinoma (DTC) follow-up. Our aim was to investigate whether anxiety, depression and quality of life are affected in DTC patients followed-up with exogenous SCH.

Materials and methods

The patients were divided into exogenous SCH by LT4-DTC (n = 127), euthyroid-DTC (n = 66) and exogenous euthyroid-benign thyroid noduüle (BTN) who underwent thyroidectomy for benign thyroid pathology (n = 85) groups.

Results

The rate of moderate/severe anxiety was significantly higher in SCH-DTC than euthyroid-BTN group (27.5%, n = 35 vs. 9.4%, n = 8) (P = 0.001). TSH levels and Beck anxiety inventory (BAI) scores were significantly negatively correlated(P = 0.009 r = –0.16). Free T4 and BAI were significantly positively correlated (P = 0.04 r = 0.4). The groups were similar in terms of depression severity (P = 0.15). Subclinical hyperthyroid-DTC group scored significantly lowerthan euthyroid-BTN group in all scales of SF-36 quality of life survey.

Conclusion

LT4-induced SCH, which is a part of traditional DTC treatment, can exacerbate the anxiety symptoms in patients and disrupt their quality of life, depending on the level of fT4.

Quality of life of patients more than 1 year after surgery for thyroid cancer

PURPOSE

Patients with thyroid cancer are often assumed to have no quality of life (QOL) impairments after treatment because of thyroid cancer's good prognosis. However, the QOL implications of surgical complications and the necessity to take lifelong medication are seldom assessed.

METHODS

Patients who had surgery due to thyroid cancer at the University Medical Center Mainz between 2010 and 2015 and who had calcium or parathyroid hormone levels below the reference values immediately following surgery were eligible for this study. QOL was assessed using the EORTC QLQ-C30 and the thyroid cancer module EORTC QLQ-THY34. Multiple logistic regression was used to determine factors associated with a worse QOL compared with a general population.

RESULTS

A total of 75 (56%) of 134 eligible patients participated in the study. Patients with persistent/prolonged calcium or vitamin D intake reported worse QOL in the domains of global health, physical functioning, role functioning, emotional functioning, and insomnia than patients without current intake. Current calcium and vitamin D intake, higher education, living with a partner, and age had an effect on the odds of having worse QOL than the age- and sex-adjusted general population.

CONCLUSION

Prolonged calcium and/or vitamin D intake are negatively associated with certain domains of QOL in thyroid cancer patients who are at least 1 year post surgery. Assessment of calcium and vitamin D and diagnosis of hypoparathyroidism are therefore important for the follow-up of thyroid cancer survivors since it may affect their QOL.

Health-Related Quality of Life After Diagnosis and Treatment of Differentiated Thyroid Cancer and Association With Type of Surgical Treatment

Importance

Concerns around possible overdiagnosis and overtreatment of differentiated thyroid cancer (DTC) have been raised. Issues concerning health-related quality of life (HRQOL) after diagnosis and treatment of DTC are understudied in this patient group.

Objective

To better understand the range of HRQOL outcomes, including possible adverse effects of treatment, associated with diagnosis and treatment of DTC and whether these outcomes vary by type of surgery received.

Design, Setting, and Participants

This content analysis assessed responses to an open-ended question about outcomes and concerns after DTC diagnosis and treatment among patients ascertained from the major postsurgical thyroid cancer treatment center and the population-based Cancer Registry in Queensland, Australia. Participants were aged 18 to 79 years and recently diagnosed with throid cancer. Responses underwent analysis to identify and code emergent themes to describe HRQOL issues and adverse effects of treatment experienced. Quantitative analysis was used to explore whether surgery type was associated with HRQOL issues and/or adverse effects of treatment. Of 1416 eligible patients, 1005 (71.0%) participated. Data were collected from July 1, 2013, through August 31, 2016, and analyzed from January 11 through April 9, 2018.

Main Outcomes and Measures

Issues concerning HRQOL.

Results

The analysis included 1005 patients (72.2% female [n = 726]; mean [SD] age, 52 [14.0 years) with DTC. Most patients were diagnosed with papillary thyroid cancer (889 of 1003 [88.6%]), had tumors smaller than 2 cm in size (564 of 1000 [56.4%]), and received a total thyroidectomy (791 of 1005 [78.7%]). Overall, 775 patients (77.1%) reported HRQOL issues after diagnosis and treatment of DTC. The following 4 main themes emerged from content analysis of patient responses: physical (663 [66.0%]), psychological (187 [18.6%]), lifestyle (82 [8.2%]), and no issue or adverse effect (246 [24.5%]). Patients who had a total thyroidectomy (without neck dissection) were 1.5 times (odds ratio, 1.49; 95% CI, 1.04-2.12) more likely to report an HRQOL issue or an adverse effect of treatment compared with patients who underwent a hemithyroidectomy.

Conclusions and Relevance

According to results of this study, patients diagnosed with DTC report wide-ranging HRQOL issues; these are more prevalent among patients who have total thyroidectomies rather than hemithyroidectomies. For patients with small, localized DTCs, hemithyroidectomy may offer fewer adverse effects of treatment and better HRQOL outcomes than total thyroidectomy. It appears that issues with HRQOL should be considered by patients and physicians when deciding on the best treatment approach after a diagnosis of DTC.

Screening for differentiated thyroid cancer in selected populations

The main purpose of cancer screening programmes should not be to detect all cancers, but to discover potentially fatal or clinically relevant cancers. The US Preventive Services Task Force recommends against screening for thyroid cancer in the general, asymptomatic adult population, as such screening would result in harms that outweigh any potential benefits. This recommendation does not apply to patients with symptoms or to individuals at increased risk of thyroid cancer because of a history of exposure to ionising radiation (in childhood, as radioactive fallout, or in medical treatment as low-dose radiotherapy for benign conditions or high-dose radiation for malignancy), inherited genetic syndromes associated with thyroid cancer (eg, familial adenomatous polyposis), or one or more first-degree relatives with a history of thyroid cancer. We discuss the evidence for and against screening individuals who are at high risk, and consider the different screening tools available.

Risk Factors of Deterioration in Quality of Life Scores in Thyroid Cancer Patients After Thyroidectomy

Objective

Despite the expectation of normal life expectancy for thyroid cancer, there are concerns about the decreased quality of life (QoL). The present study investigated the potential risk factors of deterioration in QoL scores in thyroid cancer patients after thyroidectomy.

Materials and methods

A total of 286 patients who were diagnosed with thyroid cancer after thyroidectomy were involved in this prospective, single-center, observational study from November 2018 to June 2019. The European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 was used to assess the QoL 3 months after thyroidectomy. We investigated the effects of demographics (age, gender, education, marital status, area of residence, and annual mean income), tumor characteristics (histology, clinical stage, presence of metastasis, surgery type, and radiotherapy), and neurological deficits induced by recurrent nerve or superior laryngeal injury on QoL.

Results

The mean overall QoL in thyroid cancer survivors was 65.93 ±9.00 (on a scale of 0–100, where 100 was the best). Multivariate regression analysis confirmed that clinical stage (P < 0.010), surgery type (P < 0.001), histology (P < 0.001), neurological deficits (P < 0.001), and marital status (P < 0.001) were independent risk factors for decreased QoL 3 months after thyroidectomy.

Conclusion

Our study indicated that clinical stage, surgery type, histology, neurological deficits, and marital status were independent risk factors for decreased QoL at 3 months after thyroidectomy. Further exploration and validation of these findings in larger prospective studies are warranted.

A Qualitative Analysis of the Preoperative Needs of Patients With Papillary Thyroid Cancer

BACKGROUND

Thyroid cancer patients report unmet needs after diagnosis. However, little is known about their specific needs. Therefore, we sought to characterize the needs of patients with thyroid cancer before undergoing surgery.

MATERIAL AND METHODS

We conducted semistructured interviews with 32 patients with papillary thyroid cancer after their preoperative surgical consultation. Data were analyzed using thematic content analysis.

RESULTS

The central need of patients with thyroid cancer was a strong patient-surgeon relationship characterized by informational and emotional support, and respect for the patient as a person. Patients preferred disease- and treatment-related information to be individualized and to take into account aspects of their daily life. They wanted adequate time for asking questions with thoughtful answers tailored to their case. Patients additionally desired emotional support from the surgeon characterized by empathy and validation of their cancer experience. They particularly wanted surgeons to address their fears and anxiety. Patients also highly valued the surgeons' ability to see beyond their disease and acknowledge them as a unique person with respect to their occupation, psychosocial state, and other individual characteristics. When surgeons met patients' needs, they felt reassured, comfortable with their cancer diagnosis, and prepared for treatment. Suboptimal support increased patients' anxiety particularly when they felt the surgeon minimized their concerns.

CONCLUSIONS

Preoperatively, patients with thyroid cancer desire a strong patient-surgeon relationship. They rely on the surgeon to provide adequate informational and emotional support and respect them as individuals. In turn, patients feel reassured and prepared for treatment.

Mindfulness-based stress reduction in patients with differentiated thyroid cancer receiving radioactive iodine therapy: a randomized controlled trial

Objective

The aim of this study was to evaluate the efficacy of mindfulness-based stress reduction (MBSR) on health-related quality of life (QoL), depression, and anxiety in patients with differentiated thyroid cancer (DTC) receiving radioactive iodine therapy (RIT).

Patients and methods

A randomized controlled trial of MBSR with 120 DTC patients was performed. They were randomly assigned into the MBSR intervention group and usual care (UC) group. An 8-week MBSR program was administered to the MBSR group starting 8 weeks before RIT. Health-related QoL, depression, and anxiety were measured immediately before the start of MBSR (T1), immediately after RIT hospitalization was concluded (1 week after concluding the last MBSR session, T2), and 3 months after RIT hospitalization (T3), using the QoL Questionnaire Core 30 Items (QLQ-C30), Self-rating Depression Scale (SDS), and Self-rating Anxiety Scale (SAS).

Results

Fifty-three patients in the UC group and 49 patients in the MBSR group completed the study and were analyzed. Both the UC and MBSR groups reported low QoL and high SDS and SAS scores immediately after RIT hospitalization. Patients randomly assigned to the MBSR group showed significantly greater improvements in emotional function (P=0.012, d=-0.03 for T2 and d=1.17 for T3), fatigue (P=0.037, d=1.00 for T2 and d=-0.69 for T3), global QoL (P=0.015, d=1.61 for T2 and d=1.56 for T3), depression (P=0.027, d=-1.19 for T2 and d=-0.83 for T3), and anxiety (P=0.043, d=-1.00 for T2 and d=-0.86 for T3).

Conclusion

An 8-week MBSR program significantly improved a wide range of scales in health-related QoL and mitigated depression and anxiety among DTC patients receiving RIT.

Fear of Recurrence and View of Life Affect Health-Related Quality of Life in Patients with Differentiated Thyroid Carcinoma: A Prospective Swedish Population-Based Study

BACKGROUND

Differentiated thyroid cancer (DTC) has a good prognosis but a remaining risk of recurrence and need for lifelong follow-up. The aim was to study changes in health-related quality of life (HRQoL) from diagnosis to one year of follow-up.

METHODS

In this prospective population-based study, patients were identified from all the Swedish departments of oncology treating DTC. In total, 487 patients diagnosed with DTC between 2012 and 2017 were invited to answer the Swedish version of the Short Form-36 Health Survey (SF-36) and a study-specific questionnaire at diagnosis and after one year.

RESULTS

In total, 349 (72%) patients responded. Of these, 235 (67%) had reached one year of follow-up and also answered the questionnaire after one year. Of those, 23% had a negative view of life, and 75% had a fear of recurrence at diagnosis. These patients had a significantly lower HRQoL on eight and five of the SF-36 domains, respectively (p < 0.05). A negative view of life and a fear of recurrence also affected HRQoL negatively after one year of follow-up, with a significantly lower HRQoL on seven SF-36 domains for those reporting a negative view of life or fear of recurrence often (p < 0.05). Thyrotropin suppression did not affect HRQoL negatively. In regression models, HRQoL at diagnosis was the most important predictive factor for HRQoL at the one-year follow-up.

CONCLUSIONS

Despite a good prognosis, HRQoL was substantially affected at the time of diagnosis, with some improvements after one year. As fear of recurrence and a negative view of life substantially affect HRQoL, these patients should be given additional attention.

Health-Related Quality of Life of Community Thyroid Cancer Survivors in Hangzhou, China

BACKGROUND

The purpose of this study was to evaluate health-related quality of life (HRQoL) of community thyroid cancer survivors in Hangzhou, China, and to explore the important correlates defining HRQoL.

METHODS

All thyroid cancer patients who met study criteria in 183 communities were invited to participate (N = 1551). A self-administered questionnaire including collection of personal information and HRQoL instruments was completed by each participant (n = 970), with a response rate of 62.5%. HRQoL was assessed using the Short Form 36 Health Survey and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire. Data for comparison were derived from a representative Hangzhou community sample (N = 1790). After bivariate analyses, multiple linear regression analyses were conducted to investigate independent associations between socio-demographic variables, clinical characteristics, life-style behaviors, and HRQoL.

RESULTS

Information from 965 participants was available for analysis. A total of 92.1% were diagnosed with papillary thyroid cancer, known as the most common type of thyroid cancer. In general, thyroid cancer survivors have impaired quality of life compared to the age- and sex-matched reference population using the Short Form 36 Health Survey. Thyroid cancer survivors reported the highest level of fatigue and insomnia. Multivariable regression analyses showed that being employed, higher education, and per capita disposable income (24,000-56,000 ¥ per year), and undertaking 30 minutes of moderate physical activity at least five days a week were independent correlates of high physical component summary scores, while being overweight or obese and having a higher dose of levothyroxine intake per day had a negative influence. Being employed, higher per capita disposable income (>56,000 ¥ per year), undertaking 30 minutes of moderate physical activity at least five days a week, and eating more fruit were positively associated with mental component summary scores, while females and patients having more surgeries reported lower mental component summary scores. The global quality of life scale scores were associated with education, employment status, marital status, per capita disposable income, physical activity per week, fruit intake per day, and type of surgery.

CONCLUSION

Although patients with thyroid cancer have a very good prognosis overall, in this study, they often experienced more problems than the community reference population, independent of their age and sex. Sex, education, marital status, employment status, weight status, per capita disposable income, number of surgeries, type of surgery, physical activity per week, fruit intake, and levothyroxine intake per day are important correlates of HRQoL of thyroid cancer survivors. Awareness of these relevant factors could help healthcare professionals provide better supportive care.

Following patient pathways to psycho-oncological treatment: Identification of treatment needs by clinical staff and electronic screening

OBJECTIVE

In this retrospective investigation of patient pathways to psycho-oncological treatment (POT), we compared the number of POT referrals before and after implementation of electronic screening for POT needs and investigated psychosocial predictors for POT wish at a nuclear medicine department.

METHODS

We extracted medical chart information about number of referrals and extent of follow-up contacts. During standard referral (November 2014 to October 2015), POT needs were identified by clinical staff only. In the screening-assisted referral period (November 2015 to October 2016), identification was supported by electronic screening for POT needs. Psychosocial predictors for POT wish were examined using logistic regression.

RESULTS

We analysed data from 487 patients during standard referral (mean age 56.4 years; 60.2% female, 88.7% thyroid carcinoma or neuroendocrine tumours) of which 28 patients (5.7%) were referred for POT. Of 502 patients in the screening-assisted referral period (mean age 57.0 years; 55.8% female, 86.6% thyroid carcinoma or neuroendocrine tumours), 69 (13.7%) were referred for POT. Of these, 36 were identified by psycho-oncological (PO) screening and 33 by clinical staff. After PO-screening implementation, referrals increased by a factor of 2.4. The strongest predictor of POT wish was depressive mood (P < .001). During both referral periods, about 15% of patients visited the PO outpatient unit additionally to inpatient PO consultations.

CONCLUSIONS

Our results provide evidence from a real-life setting that PO screening can foster POT referrals, reduce barriers to express the POT wish, and hence help to meet psychosocial needs of this specific patient group. Differences between patients' needs, wish, and POT uptake should be further investigated.

Psychosocial Impact of Cancer

Diagnosis and treatment of malignant diseases affect in many ways the lives of patients, relatives and friends. Common reactions immediately after the diagnosis are shock and denial, frequently followed by depression, anxiety and/or anger. About a third of all cancer patients suffer from a co-morbid mental health condition, requiring professional support by the entire medical team, including psycho-oncologists. Often overlooked issues are financial and social problems due to inability to work or due to out-of-pocket costs for the medical treatment.

Quality of life in patients with hypoparathyroidism receiving standard treatment: a systematic review

PURPOSE

Hypoparathyroidism is a rare endocrine disorder for which replacement therapy of the missing parathyroid hormone is not the standard therapeutic option. Current standard treatment consists of calcium and vitamin D supplementation. The intake of calcium and vitamin D supplementation can lead to complications and therefore might negatively influence patients' quality of life.

METHODS

A systematic literature review was performed to assess the current knowledge on the influence of hypoparathyroidism on patients' quality of life. The literature search was conducted in PubMed and Web of Science; all relevant literature published by August 24, 2016, was included.

RESULTS

In total 372 records were found. After title and abstract screening, 14 studies remained for a full-text screening. The full-text screening resulted in five studies which were included into the systematic review. Comparing the results with a norm-based reference population, three studies reported lower SF-36 scores for hypoparathyroidism patients. Two studies showed a reduced quality of life in hypoparathyroidism patients when their results were compared to control populations.

CONCLUSION

Most hypoparathyroidism patients receiving standard treatment show stable calcium and vitamin D levels. However, hypoparathyroidism patients still report reduced quality of life and experience physical, mental, and emotional symptoms. Therefore, it is assumed that the lack of parathyroid hormone directly influences the patients' quality of life. This review indicates that patients with hypoparathyroidism have a reduced quality of life in comparison to norm-based populations or matched controls. Further studies are required to quantify the effect of hypoparathyroidism on patients' quality of life using disease-specific questionnaires and controlling for the co-morbidities and etiologies of the patients.

Effect of Thyroid-Related Symptoms on Long-Term Quality of Life in Patients with Differentiated Thyroid Carcinoma: A Population-Based Study in Sweden

BACKGROUND

Differentiated thyroid cancer (DTC) has a good prognosis but a remaining risk of recurrence, and life-long follow-up as well as medication with levothyroxine may be necessary. The aim of this study was to clarify how thyroid-related symptoms affect health-related quality of life (HRQoL) 14-17 years after diagnosis in Swedish DTC patients.

METHODS

From the all-encompassing population-based Swedish Cancer Registry, 353 patients diagnosed with DTC during 1995-1998 were identified and invited to answer a study-specific questionnaire and the HRQoL questionnaire SF-36 14-17 years after their diagnosis. Subgroups were studied according to thyroid-related symptoms, both symptoms correlated to thyroid disease or levothyroxine treatment and side effects from surgery and radioiodine treatment.

RESULTS

Of the patients with DTC, 279 (79%) answered the questionnaires. In all, only 19 (7%) reported a recurrence. Patients with one single symptom (e.g., fatigue, sleeping disorders, irritability, lower stress resistance, muscle weakness, bodily restlessness, sweating, palpitations, or flushes) had significantly lower HRQoL measured with the SF-36 compared to those without that specific symptom (p < 0.001). Furthermore, those 238 patients with at least one symptom, regardless of which one, had significantly lower HRQoL in all eight SF-36 domains compared to patients that no thyroid symptom (n = 34; p < 0.001). In seven patients, the questionnaires were not complete in terms of the thyroid-related questions. The association between thyroid symptoms and lower HRQoL remained after adjusting for age, sex, comorbidities, education, and menopause.

CONCLUSIONS

DTC patients reporting thyroid symptoms scored lower in HRQoL compared to those with no symptoms >14 years after diagnosis.
