Efficacy and Safety of Low Dose Vandetanib in Metastatic Medullary Thyroid Cancer Abstract #1758

Introduction: Medullary thyroid cancer (MTC) is an aggressive thyroid malignancy. Vandetanib is a tyrosine kinase inhibitor approved for locally advanced or metastatic MTC, administered orally 300 mg/daily. Diarrhea, hypertension and QT prolongation are common side effects and may require withdrawal or dose reduction.
Aim(s): Aim of this study was to evaluate efficacy and safety of low dose vandetanib (200 mg/daily) in progressive metastatic MTC.
Materials and methods: Clinical, biochemical and radiological records of 6 patients with metastatic MTC were retrospectively evaluated. All pts were negative for RET mutation and had progressive disease after surgery and experimental therapy with pasireotide.

#48 Preliminary report of the use of everolimus in a patient with progressive medullary thyroid carcinoma
Introduction: Medullary thyroid carcinoma (MTC) accounts for about 5-10% of all thyroid cancers, and while disease localized to the thyroid can be cured by surgery, there is no effective treatment for disseminated MTC. Constitutive activation of the RET proto-oncogene is implicated in familial and a proportion of sporadic cases, and up-regulates the AKT/PI3-kinase/mTOR signal transduction pathway. Recent studies have shown that the inhibitor of mTOR, everolimus (RAD001, Novartis, Basel), can inhibit the proliferation of the TT cell line and human MTC tumor cells in vitro. Clinically, everolimus has been shown to attenuate the progression of some gastrointestinal neuroendocrine tumors, but its clinical use in MTC has not yet been evaluated.

#66 Adrenocortical cancer: a therapeutic approach with everolimus (RAD001)
Introduction: Adrenocortical cancer (ACC) is a rare disease with very poor outcome. ACC responds poorly to standard chemotherapy. Mitotane, used as adjuvant therapy to surgery, prolongs recurrence-free survival, but the response is limited to 23% of patients and resistance occurs in the majority of patients (1). There is no curative therapy for ACC. Pre-clinical studies have shown involvement of both IGF-2/IGF-1R and Akt/mTOR pathways in ACC, and IGF-1R and mTOR inhibitors inhibited cell proliferation of human adrenocortical carcinoma cell lines in vitro (2,3,4).

#108 Everolimus (RAD001) induces tumor response in patients with medullary thyroid cancer: an in vivo and in vitro study
Introduction: Medullary thyroid cancer (MTC) is a neuroendocrine tumor (NET) of the thyroid C cells which is known to express somatostatin receptors. Octreotide, a somatostatin analogue exerting both antisecretory and antitumor activity in different types of NETs, has shown low efficacy in MTC. Everolimus (RAD001), an inhibitor of mTOR, has shown antitumor effects in patients with NETs and synergistic effects when combined with octreotide. Until recently, RAD001 has never been evaluated in MTC.
