Pemetrexed-carboplatin salvage therapy in advanced thyroid cancers.

Background: The overall survival of patients with advanced thyroid cancers that have progressed following targeted therapies is limited, indicating a strong need for salvage treatments.

Methods: We retrospectively analyzed patients with refractory advanced thyroid cancer treated with pemetrexed-carboplatin (PC) at Mayo Clinic since 2019.

Results: Eleven patients, three with anaplastic thyroid cancer (ATC), seven with differentiated or poorly differentiated thyroid cancer (DTC), and one with oncocytic carcinoma of the thyroid, were treated with novel salvage PC.

Lenvatinib as a Therapeutic Option in Unresectable Metastatic Pheochromocytoma and Paragangliomas.

Context: Metastatic pheochromocytomas and paragangliomas (mPPGL) are rare vascular neuroendocrine tumors that highly express vascular growth factors. Systemic treatment options in cases of unresectable multisite disease are limited. Multikinase inhibitors that inhibit angiogenesis, such as lenvatinib, have proven effective in several other malignancies, and may be a viable option for mPPGL.

Foundation One Genomic Interrogation of Thyroid Cancers in Patients With Metastatic Disease Requiring Systemic Therapy.

Context: Clinical applications of genomic assessment of thyroid cancers are rapidly evolving.

Objectives, Design, And Setting: We studied tumor samples from patients with imminently threatening and rare thyroid cancers to identify genomic alterations that might correlate with outcomes and/or be productively therapeutically targetable.

Patient Context: Progressive and metastatic, and/or rare, thyroid cancers were studied, 2012 to 2016, at Mayo Clinic sites.

OPTIMIZING LENVATINIB THERAPY IN PATIENTS WITH METASTATIC RADIOACTIVE IODINE-RESISTANT DIFFERENTIATED THYROID CANCERS.

Objective: Lenvatinib is approved for use in advanced radioactive iodine-resistant differentiated thyroid cancers (RAIR-DTCs). Its efficacy is indisputable, but toxicities are great, creating daunting challenges for patients and providers. Few data regarding early adverse events and impact on quality of life (QOL) exist; we sought to clarify these issues by analyzing our initial postapproval lenvatinib experience.

Salvage Lenvatinib Therapy in Metastatic Anaplastic Thyroid Cancer.

Background: Historical anaplastic thyroid cancer (ATC) outcomes have been terrible, with a median survival of only five months and <20% one-year survival. Improved outcomes are now achieved with aggressive initial therapy in stages IVA and IVB disease, but patients with distant metastatic disease (stage IVC) still do poorly; improved therapies are sorely needed. Kinase inhibitors have emerged as promising agents in the therapy of advanced medullary and differentiated thyroid cancer, but there are limited data regarding the use of lenvatinib in ATC.

An analysis of fosaprepitant-induced venous toxicity in patients receiving highly emetogenic chemotherapy.

Purpose: Fosaprepitant is an antiemetic used for chemotherapy-induced nausea and vomiting. We recently reported increased infusion site adverse events (ISAE) in a cohort of breast cancer patients receiving chemotherapy with doxorubicin and cyclophosphamide (AC). In this current study, we evaluated the venous toxicity of fosaprepitant use with non-anthracycline platinum-based antineoplastic regimens.
