Drug resistance is a perpetual problem in cancer therapy with many underlying mechanisms. Alterations in drug transport over the cancer cell membrane can severely alter intratumoral drug exposure, contributing to resistance. Here, we present the somatic mutational landscape of 48 ATP-binding cassette and 416 solute carrier transporter genes in a co...
Article
The use of anticancer drugs targeting specific molecular tumor characteristics is rapidly increasing in clinical practice, but selecting patients to benefit from these remains a challenge. It has been suggested that organoid cultures would be ideally suited to test drug responses in vitro. Here we describe and characterize in depth a case of ETV6-N...

Purpose: For prostate-specific membrane antigen-directed radioligand therapy (PSMA-RLT), [177Lu]Lu-PSMA-617 and [177Lu]Lu-PSMA-I&T are the currently preferred compounds. Recent preclinical studies suggested ~30x higher kidney absorbed dose for [177Lu]Lu-PSMA-I&T compared to [177Lu]Lu-PSMA-617, which may lead to an increased risk of kidney toxicity...

Objective: Three-dimensional organoid cell cultures have been established for a variety of human cancers. For most rare cancers, including salivary gland cancer (SGC), these models are lacking, despite the great unmet need to study cancer biology in these diseases. Therefore, we aimed to develop patient-derived organoid (PDO) models for different...

Introduction: Salivary gland cancer (SGC) is a rare cancer for which systemic treatment options are limited. Therefore, it is important to characterize its genetic landscape in search for actionable aberrations, such as NTRK gene fusions. This research aimed to identify these actionable aberrations by combining NGS-based analysis of RNA (gene fusio...

A cancer is considered rare when the annual cancer incidence is less than 6 per 100,000 inhabitants. In absolute numbers more than 500,000 patients per year are diagnosed with a rare cancer, and 4,300,000 rare cancer patients are prevalent in Europe. The definition is widely adopted among the different scientific international societies like ESMO a...

3613 Background: Mutations in the KRAS gene result in a constitutively activated RAS-RAF-MEK-ERK (MAPK) pathway. In KRAS mutant tumors, the anti-tumor activity of MEK inhibitors is limited due to intrinsic resistance caused by feedback activation of upstream epidermal growth factor receptors (HER). This upstream activation not only reactivates MAPK...
