Thyroid cancer is the most common cancer among Korean women. However, there are few data on dietary factors related to thyroid cancer risk. The objective of the present study was to evaluate the association between raw vegetables and fruits intake and thyroid cancer in a case–control study. We included 111 histologically confirmed malignant thyroid cancer cases and 115 benign cases. Controls who did not have nodules in thyroid ultrasonography were matched to cases by age ( ± 2 years). Food and nutrient intakes were estimated using a quantitative FFQ with 121 items. Conditional logistic regression analysis was used to obtain OR and corresponding 95 % CI. The intake of total vegetables was not associated with malignant thyroid cancer, but inversely associated with benign cases. High raw vegetable intake was inversely associated with thyroid cancer risk both in malignant and benign cases (P for trend = 0·01 in both malignant and benign cases). Among fruits, persimmon intake had an inverse association with thyroid cancer risk in both malignant and benign cases (P for trend = 0·06 in malignant cases; P for trend = 0·01 in benign cases) and tangerine intake had an inverse association in malignant cases (P for trend = 0·03). The frequency of consumption of raw vegetables and persimmon also had a consistent inverse association in both malignant and benign cases. These results suggest that high consumption of raw vegetables, persimmons and tangerines may decrease thyroid cancer risk and help prevent early-stage thyroid cancer.

Background: Familial NMTCs are supposed to be more aggressive and require more frequent treatment compared to non-familial thyroid cancer. Objectives: This matched case-control study aimed to compare the response to treatment between the matched case-control groups of familial and sporadic NMTC. Methods: This is a retrospective study in patients with familial NMTC (at least one other first-degree relative involved) who were treated with surgery, followed by radio-iodine therapy (RIT) without consideration of its familial origin. Response to treatment was compared between familial NMTC and age, sex, and TNM stage-matched non-familial NMTC (control group). Response to treatment was assessed one and two years after RIT, and time to excellent response was identified. Results: Out of 2,944 NMTC patients, 81 (2.75%) patients had familial NMTC. We compared 66 patients with familial NMTC and 66 sporadic NMTC patients. There was no significant difference in first thyroglobulin, initial and accumulative iodine dose, and additional treatments (additional surgery and radiotherapy) between patients and controls. Although no significant difference was noted in one and two years’ responses to treatment between the case and control groups, familial NMTC patients required more time to achieve excellent response (26.7 ± 24.9 versus 15.9 ± 9.0 months, P = 0.01). No significant difference was noted between familial NMTC patients with two or more than two involved relatives. Conclusions: Our study showed that if patients with familial NMTCs were treated in the same way as non-familial patients, the time to excellent response would be significantly longer, even when they have only one other involved relative.

Abstract Background Aetiology of differentiated thyroid cancer is poorly understood. Among the risk factors strongly suspected to be involved in thyroid carcinogenesis are dietary factors. Recent evidence suggests polyphenols (i.e., natural bioactive compounds found in plant species), and their anticancer properties, may deserve closer epidemiological attention. Therefore, we examined the association between polyphenol intake levels and thyroid cancer risk in New Caledonia – a Pacific archipelago with some of the highest recorded thyroid cancer incidence rates in the world. Methods Food frequency questionnaire information from a population-based case-control study was used. Daily lignan and flavonoid intakes, expressed as aglycone equivalents, were estimated using Phenol-Explorer and relevant USDA databases. Unconditional logistic regression analyses were performed on data from 324 histologically confirmed cases of papillary or follicular carcinoma, diagnosed from 1993 to 1999, and 402 controls. Polyphenol intakes were analysed as both continuous and categorical variables (quartiles). Results Estimated median flavonoid and lignan intakes were 351.0 and 2.6 mg, respectively. When adjusting for sex, age, ethnic community, province of residence, BMI, smoking status, alcohol consumption and energy intake, no association with differentiated thyroid cancer risk was observed for flavonoids (OR = 1.06, 95% CI: 0.66, 1.70; comparing extreme quartiles), but a negative association was demonstrated for lignans (ORQ4vs.Q1=0.60, 95% CI: 0.37, 0.96; comparing extreme quartiles). Conclusions Our findings suggest that lignans may exert a protective effect on differentiated thyroid cancer. However, large-scale cohort studies and further analytical data on lignans are required to confirm this association. Key messages Lignans may play a role in thyroid carcinogenesis.
