Recurrent Carcinoma of Unknown Primary

Current Clinical Trials

The prognosis for any treated cancer patient with progressing, recurring, or relapsing disease is poor, regardless of cell type or stage. Deciding on further treatment depends on many factors, including the specific cancer, prior treatment, and site of recurrence, as well as individual patient considerations. Treatments that are under clinical evaluation are appropriate and should be considered when possible. Information about ongoing clinical trials is available from the NCI Web site.
