Cancer of Unknown Primary Platform

the Netherlands

Welcome to the homepage of CUPP-NL, Cancer of Unknown Primary (CUP) Platform the Netherlands.

CUPP-NL is the expert platform in the Netherlands that is committed to patients with metastatic cancer whose primary tumor cannot be found. By raising awareness and increasing collaboration both nationally and globally, pooling current knowledge and stimulating scientific research, we aim to improve diagnostics and treatment options for CUP patients and CUP patient care in general.

For patients and their family members, we would like to kindly refer you to patient organization Missie Tumor Onbekend whose volunteers are dedicated to providing information and support to patients in a CUP patient journey. They are off course also able to help you in Dutch.
