Rising incidence, no change in survival and decreasing mortality from thyroid cancer in The Netherlands since 1989.

The incidence of thyroid cancer (TC) is increasing worldwide, partly due to increased detection. We therefore assessed combined trends in incidence, survival and mortality of the various types of TC in The Netherlands between 1989 and 2009. We included all patients ≥15 years with TC, diagnosed in the period 1989-2009 and recorded in The Netherlands Cancer Registry (n=8021).

Health-related quality of life and disease specific symptoms in long-term thyroid cancer survivors: a study from the population-based PROFILES registry.

Background: Given the longevity of thyroid cancer patients, any impairment in health-related quality of life (HRQoL) during the follow-up period is of considerable concern. Therefore, the first aim of this study was to assess (thyroid cancer specific) HRQoL among long-term thyroid cancer survivors and to compare this with the HRQoL of an age- and sex-matched normative population. Secondly, our aim was to investigate which clinical and socio-demographic characteristics and thyroid cancer specific problems were associated with HRQoL.

Comorbidity in newly diagnosed thyroid cancer patients: a population-based study on prevalence and the impact on treatment and survival.

Background: Comorbidity may be an important contributory factor to differences in the treatment and outcome of cancer, especially in older patients. It might also provide information on the aetiology of the cancer in cases of high or low frequency. The aim of this study was to describe the spectrum of comorbidity and the possible impact on treatment and survival in newly diagnosed thyroid cancer (TC).

Hypothyroidism might be related to breast cancer in post-menopausal women.

An association between breast cancer and thyroid (autoimmune) diseases or the presence of thyroid peroxidase antibodies (TPOAb; a marker of thyroid autoimmune disease) has been suggested. However, little is known about whether women with thyroid (autoimmune) diseases are at increased risk for developing breast cancer. This cross-sectional and prospective cohort study investigated whether the presence of TPOAb or thyroid dysfunction is related to the presence or development of breast cancer.
