Updates in molecular diagnosis and targeted treatment of thyroid neoplasia
The registered drugs for this purpose include molecularly targeted therapy with the tyrosine kinase inhibitors (TKIs) lenvatinib, sorafenib, and as second-line cabozantinib. These agents were shown to delay progressive disease in clinical trials, but not overall survival. Moreover, the setting of a clinical trial is often stricter than real-life, as reflected by less favorable outcomes in real-world data. Furthermore, these drugs frequently have (intolerable) adverse events. When the limited treatment options for refractory thyroid cancer have been exhausted, inclusion in clinical...Show moreThyroid cancer is a rare cancer with an excellent prognosis with standard care (including surgery and radioactive iodine therapy). However, a minority may show progression to refractory status. These advanced radioactive iodine-refractory thyroid cancer patients often have an aggressive disease course and poor prognosis. Unfortunately, no good treatment options are available for these patients.
The registered drugs for this purpose include molecularly targeted therapy with the tyrosine kinase inhibitors (TKIs) lenvatinib, sorafenib, and as second-line cabozantinib. These agents were shown to delay progressive disease in clinical trials, but not overall survival. Moreover, the setting of a clinical trial is often stricter than real-life, as reflected by less favorable outcomes in real-world data. Furthermore, these drugs frequently have (intolerable) adverse events. When the limited treatment options for refractory thyroid cancer have been exhausted, inclusion in clinical trials is often recommended by international guidelines.
More recent ‘basket trials’ also study tumor type-agnostic prescription of drugs based on molecular tumor profiling; e.g. an ALK TKI in presence of an ALK gene fusion. The molecular characterization of neoplasms may also improve diagnosis and/or help direct the further management strategy; e.g. in indeterminate thyroid cytopathology, or in specific cases of Multi-UniFocality in contrast to multifocality.
