  • *Period I: January 1, 2016, until July 1, 2018. Period II: July 1, 2018, until January 1, 2020.

  • †Unsuccessful tumor test and no subsequent referral for germline test.

  • ‡Patient withdrew from germline testing after tumor pathogenic variant was detected.

  • §All tumor tests were performed after July 1, 2018.

  • ¶25 patients diagnosed in period I received both a tumor and germline test. The tumor tests were performed after a conclusive germline test indicated the absence of a germline pathogenic variant, to potentially detect a tumor pathogenic variant.
