Background: Invasive pituitary tumors may behaviour like some pituitary carcinomas. Although invasiveness is not indicative of malignancy, it probably puts the patient at higher risk of developing a pituitary carcinoma.

Pituitary adenomas account for ~10–15% of intracranial tumors and result in morbidity due to both altered hormonal patterns as well as side effects of therapy. Currently, great attention has been given to natural coumpouds from functional foods. Among these substances, we highlight that the consumption of carotenoids is associated with reduced risk of chronic diseases including cancer and vascular diseases. In this study we evaluate the influence of β-carotene and ly...

Background and aims: The value of the revised (2009) UICC/TNM criteria for medullary thyroid cancer (MTC) is not established. We aimed to evaluate its predictive value, analyzing the consequences of the inclusion of T3N0M0 patients previously included in stage III of the 6th edition, in stage II of the 7th.Patients and methods: We retrospectively analysed the clinical records of 85 patients operated for MTC and followed in two tertiary hospitals in the c...
