Molecular classification of cancers of unknown primary expands and refines treatment options (ESMO 2022)
When treatments changed, the drugs that were most often removed as treatments were: 5-FU (n=46), oxaliplatin (n=42), and carboplatin (n=41). Gemcitabine and cisplatin were added as treatment recommendations in 54 and 49 cases, respectively...Conclusions In our study, we demonstrate that the TO test can specify a diagnosis that alters the therapeutic management for up to 81% of patients with unknown primary. These changes include the addition and removal of chemotherapy and CPI, as well as alterations in radiation and surgical treatments, highlighting the potential of molecular classifiers to provide clinical insight into the management of CUP patients.
