    The majority of patients with cancers of unknown primary have unfavourable outcomes when they receive empirical chemotherapy. The shift towards using precision medicine-based treatment strategies involves two options: tissue-agnostic or site-specific approaches. Here, we reflect on how cytology-based deep learning tools can be leveraged in these approaches.

    The identification of the tissue of origin in patients with cancer of unknown primary (CUP) is an example of how epigenomics can be incorporated in clinical settings. Epigenetic and other molecularly-based diagnostic strategies have emerged to complement traditional diagnostic procedures, thereby improving the clinical management of patients with CUP. Herein, the authors present the latest data on strategies using epigenetics and other molecular biomarkers to guide therapeutic decisions involving patients with CUP, addressing a previously unmet need.

    Molecular cancer-classifier assays enable the diagnosis of a single cancer type for most patients with cancer of unknown primary (CUP), thus opening the door to the administration of site-specific therapies. Herein, I discuss how such therapies can improve the survival of patients with CUP, and the resulting paradigm shift towards tissue-of-origin diagnostics and treatments that is now becoming the standard of care for this patient population.

    Carcinomas of an unknown primary origin (CUP) are histologically confirmed metastases for which a primary tumor could not be found despite an extensive diagnostic workup of the patient. The authors of this Review discuss the clinical evaluation of patients with CUP, describe how to identify specific CUP subsets, and outline treatment strategies and outcomes of patients with CUP.
