Cancer of unknown primary 

Up to 5% of cancer cases are diagnosed at later stages, as metastases of an unknown primary source. In these cases, the correct diagnosis of the primary tumor is critical to tailoring the best treatment regimen for the patient and the disease.
In many cases, the histological diagnosis (of a tumor specimen obtained during a surgical biopsy) is not unequivocal, raising the need for tissue diagnosis based on its genetic code.
For these cases and for cases where the tumor source is known but the histological diagnosis (of the specific type of tumor) is uncertain, Oncotest – Advantest offers molecular tests based on advanced technologies that are able to more precisely diagnose the tumor's tissue of origin, enabling physicians to better adjust the treatment for each patient.
