Implementation and impact of the first two years of a systemwide molecular tumor board at Henry Ford Health System (HFHS).

Abstract

e19266 Background: HFHS implemented clinically-oriented Precision Medicine Program (PMP) in 2016. As part of the program, multidisciplinary molecular tumor board (MTB) was created to review complex molecular cases, providing guidance to treating medical oncologist in selecting targeted therapies and clinical trials. In some cases MTB recommended genetic counseling or recommended against/for additional molecular testing. MTB consists of oncologists, molecular pathologists, clinical trial staff, and genetic counselors. MTB was designed as teaching platform engaging hematology-oncology fellows into cases analysis and presentation. Here we present preliminary analysis of the impact of the MTB on the HFHS oncology practice. Methods: From 09/08/2017 to 12/31/2019 MTB reviewed 120 cases, 116 cases were used for this analysis. Data was abstracted using Syapse precision oncology platform, MTB recommendation note, electronic medical record (EMR), and molecular test results. Results: Out of 116 pts 83 (72%) were Caucasian, 25 (22%) African American, 4 (3%) Asian, 1 (1%) American Indian. Fifty-two % (n = 21) had an ECOG performance status of 1. Most common primary disease sites were lung (39%, n = 45) brain (12%, n = 15), and hematologic cancers (9%; n = 10), followed by breast (5%, n = 6), prostate (4%, n = 5), colon (3%, n = 4), and others (28%, n = 31). The most common genetic abnormalities discussed were atypical EGFR (n = 15), non-V600 BRAF (n = 10), KRAS (n = 8), BRCA2 (n = 5), NF2 (n = 4), PTEN (n = 4), CSF3R (n = 3), IDH1 (n = 3), TP53 (n = 3), and 29 less common mutations. Thirty five (30%) pts out of 116 total were recommended clinical trials, although only 3 patients (10% of recommended) were enrolled into trials. 31 pts (27%) were recommended off-label therapy, although trials were preferred. 18% of pts (n = 21) were recommended genetics referral, although only 3 have seen Geneticist, with two undergoing germline testing. One pt was discovered to have a germline RET V804M mutation which was originally detected in the cancer. Conclusions: The first two years of data demonstrate the utility of the MTB and provide a basis for ongoing analysis. Through multidisciplinary approach, MTB encourages care coordination and collaboration. MTB resulted in genetics referrals, clinical trial recommendations, and identification of targeted therapy options, including off label. In many cases, MTB recommendations prevented futile therapies and/or additional molecular testing.
