Overview

There is no treatment for cancer of unknown primary origin; the mainstay of therapy is supportive care. Medical therapy for cancer of unknown primary origin should be adjusted on an individual basis and according to well-defined clinicopathologic subsets.

Medical Therapy

  • There is no treatment for cancer of unknown primary origin; the mainstay of therapy is supportive care.[1]
  • The treatment for cancer of unknown primary origin will depend on several factors, such as metastatic origin, biopsy findings, patients age, and performance status.
  • Medical therapy for cancer of unknown primary origin should be adjusted on an individual basis and according to well-defined clinicopathologic subsets.[1]
  • The table below summarizes different types of medical therapy strategies for cancer of unknown primary origin according to the European Society of Medical Oncology:[2]
