Cancer of Unknown Primary Pathway

Cancer of Unknown Primary (CUP) Pathway

There has been a recent increase in the number of referrals to the Cancer of Unknown Primary (CUP) service. Many of the referrals received were missing some of the required investigations or information; or were more appropriate for a different pathway.

The CUP pathway is for those patients who have been found to have a cancer but the primary site of this cancer is unknown from preliminary investigations. The isolated weight loss pathway is a separate service for patients who have not already been identified as having cancer.

Please see attached flow chart outlining the required investigations for the CUP pathway.
