Rationale:The early detection of recurrent differentiated thyroid carcinoma (DTC) cells in postsurgery DTC patients relies on the sensitivity of measuring both the level of thyroglobulin (Tg) and 131-iodine distribution on a whole-body scan (WBS). Recent studies have defined patients who subsequently have no evidence of disease as those who have a stimulated Tg level <1 ng/mL with no other radiological or clinical evidence of disease.Patient Concerns:A woman patient with solid variant papillary thyroid carcinoma (SVPTC) had undergone twice thyroidectomy with lymph node dissection and radioactive therapy. Recently, she was found to have lung and brain metastases despite a very low serum Tg level and a negative WBS. Nowadays, the patients have suggested targeted treatment, such as tyrosine kinase inhibitors, may be worthy of consideration to prevent the related events.Diagnoses:She was diagnosed as PTC.Interventions:She had undergone twice thyroidectomy with lymph node dissection and radioactive therapy.Outcomes:She was found to have lung and brain metastases despite a very low serum Tg level and a negative WBS.Lessons:We aim to suggest that patients with SVPTC should be treated cautiously because they may have a higher frequency of distant metastases and a less favorable prognosis compared with patients with classical papillary thyroid cancer.
The aims of this study were to explore the dose-response relationship between high-risk human papillomavirus (hrHPV) load and cervical lesions; the relationship between hrHPV viral load and the severity of cervical lesions; and the clinical application of the hybrid capture II (HC-II) system in the secondary prevention of cervical cancer. HrHPV viral load was detected by the HC-II system and cervical lesions were diagnosed from biopsied tissue. Curve estimation and Mantel trend analysis were used to explore the dose-response relationship between hrHPV viral load and cervical lesions. Spearman's rank correlation analysis and ordinal regression model were used for the analysis of hrHPV viral load and the severity of cervical lesions. Curve estimation showed good correlation between cervical lesion rates and hrHPV viral load (r=0.775, P=0.008); the rate of cervical lesions increased with hrHPV viral load (chi(trend)=8.000, P<0.001). Medium intensity rank correlation was found between hrHPV viral load grades and the severity of cervical lesions (r(s)=0.321, P<0.001); a correlation appeared between hrHPV viral load and the severity of cervical lesions (P<0.001). These results suggest a dose-response relationship between hrHPV viral load and the severity of cervical lesions. This dependence has important clinical applications and shows the potential value of the HC-II system in cervical cancer prevention.
Objective
To investigate the effect of radioactive iodine therapy under thyroid hormone withdrawal in differentiated thyroid cancer patients on health-related quality of life.
Methods
Patients who were diagnosed with differentiated thyroid cancer after thyroidectomy were involved in this study. All of them were managed with thyroid hormone withdrawal. Health-related quality of life was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and its thyroid cancer module at three different time points. Changes in health-related quality of life were evaluated by Wilcoxon and Kruskal–Wallis tests. Univariable logistic regression analysis was used to determine social-demographic and clinical factors associated with worse health-related quality of life.
Results
A total of 99 differentiated thyroid cancer patients were involved in this study. Changes in health-related quality of life at different time points showed that 1 month post-radioactive iodine treatment, an improvement in nausea and vomiting, insomnia and appetite loss was observed. Impairments of global health, role, cognitive and social function and problems of discomfort in the head and neck, voice concerns, dry mouth, fatigue, pain, dyspnea, thyroid fatigue, fear, tingling or numbness, joint pain and shoulder function increased after radioactive iodine treatment. Univariable logistic regression analysis demonstrated potential factors associated with worse health-related quality of life. Thyroid stimulating hormone and parathyroid hormone levels were more sensible to changes in functional domain. Patients aged ≥55-year-old, with annual income under ¥50 000, low parathyroid hormone and pT4 tumour stage experienced higher changes in symptom scales after radioactive iodine treatment.
Conclusion
After radioactive iodine treatment, differentiated thyroid cancer patients experienced negative health-related quality of life, and most of these impairments might not recover in the short term. Thyroid stimulating hormone and parathyroid hormone levels, annual income and pT tumours stage were independent risk factors for decreased health-related quality of life.
