Objective: The aim of the present study was to investigate the differences in quality of life (QOL) following complete or partial thyroidectomy and with regard to thyroid hormone replacement (LT4) therapy.Study Design: Patients who underwent thyroidectomy were asked to complete the validated thyroid‐specific ThyPRO QOL questionnaire at least 6 months following surgery.Setting: Tertiary medical center.Methods: Thyroid specific QOL questionnaire analysis.Results: A total of 190 patients completed the ThyPRO questionnaire. Of them 89 patients had complete thyroidectomy and 101 patients had unilateral thyroid lobectomy. The total thyroidectomy group had significantly worse overall QOL self‐assessment score than the lobectomy patients (p < 0.0001). Patients receiving LT4 therapy regardless of the extent of surgery, reported worse QOL compared to patients not receiving LT4.Conclusions: Quality of life following thyroid surgery is significantly related to hypothyroidism and the requirement for LT4 therapy, rather to the extent of surgery. The best QOL was reported in patients treated with lobectomy who did not require LT4 therapy.

Background: Papillary thyroid cancer (PTC) commonly affects women of child-bearing age. During normal pregnancy, several factors may have a stimulatory effect on normal and nodular thyroid growth. The aim of the study was to determine whether pregnancy in thyroid-cancer survivors poses a risk of progression or recurrence of the disease. Methods: The files of 63 consecutive women who were followed at the Endocrine Institute for PTC in 1992–2009 and had given birth at least once after receiving treatment were reviewed for clinical, biochemical, and imaging data. Thyroglobulin levels and neck ultrasound findings were compared before and after pregnancy. Demographic and disease-related characteristics and levels of thyroid-stimulating hormone (TSH) during pregnancy were correlated with disease persistence before conception and disease progression during pregnancy using Pearson's analysis. Results: Mean time to the first delivery after completion of thyroid-cancer treatment was 5.08 ± 4.39 years; mean duration of follow up after the first delivery was 4.84 ± 3.80 years. Twenty-three women had more than one pregnancy, for a total of 90 births. Six women had evidence of thyroid cancer progression during the first pregnancy; one of them also showed disease progression during a second pregnancy. Another two patients had evidence of disease progression only during their second pregnancy. Mean TSH level during pregnancy was 2.65 ± 4.14 mIU/L. There was no correlation of disease progression during pregnancy with pathological staging, interval from diagnosis to pregnancy, TSH level during pregnancy, or thyroglobulin level before conception. There was a positive correlation of cancer progression with persistence of thyroid cancer before pregnancy and before total I-131 dose was administered. Conclusions: Pregnancy does not cause thyroid cancer recurrence in PTC survivors who have no structural or biochemical evidence of disease persistence at the time of conception. However, in the presence of such evidence, disease progression may occur during pregnancy, yet not necessarily as a consequence of pregnancy. The finding that a nonsuppressed TSH level during pregnancy does not stimulate disease progression suggests that it may be an acceptable therapeutic goal in this setting.

Background: Patients with differentiated thyroid cancer (DTC) usually have a good prognosis but may experience a decline in quality of life (QOL). The way patients perceive their illness may have a major impact on their QOL. Our hypothesis was that patients with DTC frequently perceive their illness as much more severe than its objective clinical characteristics indicate. The aim of the study was to investigate how patients with DTC perceive their illness and to correlate these findings to various demographic parameters as well as objective indices of disease severity. Methods: The self-administered Illness Perception Questionnaire-Revised (IPQ-R) was completed by consecutive patients with DTC during routine follow-up at the endocrine clinic. The questionnaire consists of three parts that measure different aspects of illness perception. The patients' medical records were reviewed for data on demographic parameters (sex, age) and indices of disease severity (duration of DTC, disease stage at diagnosis, number of operations, number of radioactive iodine treatments, and evidence of disease persistence/recurrence). The patients were also asked for additional data on family status, level of education, and employment status. Pearson and Spearman correlations and analysis of variance were used for statistical analysis. Results: The study group included 110 patients (91 women) of mean age 53.5 years. Level of education was the only demographic factor found to affect the patients' perception of their illness. There was no correlation of patient illness perception and cancer stage. Among the disease-severity parameters, time since last treatment, evidence of disease persistence, and number of iodine treatments were significantly associated with a negative disease perception. Number of iodine treatments was the most broadly affecting factor. There was a high correlation of scores among the various illness perception subscales. Conclusions: Patients with DTC perceive their illness on a subjective, emotional basis unrelated to its actual severity. To improve patients' illness representations and, consequently, their QOL, a trained psychologist should be included in the multidisciplinary team that manages patients with DTC. Attention should be particularly directed to less-educated patients and patients who require repeated iodine treatments.

Objective: Hypothyroidism during pregnancy has been associated with adverse obstetrical outcomes. Most studies have focused on subjects with a mild or subclinical disorder. The aims of the present study were to determine the relative rate of severe thyroid dysfunction among pregnant women with hypothyroidism, identify related factors and analyse the impact on pregnancy outcomes.Design: A retrospective case series design was employed.Methods: The study group included 101 pregnant women (103 pregnancies) with an antenatal serum TSH level >20.0 mIU/l identified from the 2009–2010 computerised database of a health maintenance organisation. Data were collected from the medical records. Pregnancy outcomes were compared with those of a control group of 205 euthyroid pregnant women during the same period.Results: The study group accounted for 1.04% of all insured pregnant women with recorded hypothyroidism during the study period. Most cases had an autoimmune aetiology. All women were treated with levothyroxine (l-T₄) during pregnancy. Maximum serum TSH level measured was 20.11–150 mIU/l (median 32.95 mIU/l) and median serum TSH level 0.36–75.17 mIU/l (median 7.44 mIU/l). The mean duration of hypothyroidism during pregnancy was 21.2±13.2 weeks (median 18.5 weeks); in 36 cases (34.9%), all TSH levels during pregnancy were elevated. Adverse pregnancy outcomes included abortions in 7.8% of the cases, premature deliveries in 2.9% and other complications in 14.6%, with no statistically significant differences from the control group. Median serum TSH level during pregnancy was positively correlated with the rate of abortions+premature deliveries and rate of all pregnancy-related complications (P<0.05).Conclusions: Abortions and premature deliveries occur infrequently in women with severe hypothyroidism. Intense follow-up and l-T₄ treatment may improve pregnancy outcomes even when target TSH levels are not reached.
