Abstract 519MO

Background

In the era of cancer genome medicine, the role of multidisciplinary tumor boards (MTBs) has been growing and, accordingly, the assurance of the quality of MTBs is rapidly needed. Here we present the results of a prospective analysis evaluating the concordance between treatment recommendations by the MTBs and central consensus treatment recommendations.

Methods

The central committee of the study developed 50 simulated cases which included frequently observed genomic alterations selected from The Cancer Genome Atlas database. The central committee then developed a consensus recommendation for all 50 cases, according to the Japanese practice guideline (Naito Y et al., Int J Clin Oncol 26: 233-283; 2021). The MTBs from twelve leading cancer institutes in Japan independently recommended a treatment for all 50 cases in a blinded manner to the consensus recommendations. The primary objective was to estimate the concordance rate which was defined as the proportion of treatment recommendations by MTBs that were concordant to the consensus recommendations. Mixed effects logistic regression model adjusted for institutes as random intercept was applied.

Results

In 600 (=50 cases×12 institutes) treatment recommendations by the MTBs, the adjusted rate of concordance was 62% (95% confidence interval [CI], 54-69%); the concordance rate across the MTBs varied from 50% to 86%. A high concordance was observed in the subgroups of cases with colorectal cancer (83%), ROS1 fusion (100%), and high evidence level A/R (88/100%), whereas a low concordance was seen in cases with cervical cancer (10%), TP53 mutation (16%), and low evidence level C/D/E (30/25/18%). A multivariate analysis revealed that the level of evidence (high [A/B/R] vs low [C/D/E]; odds ratios, 4.4 [95%CI; 1.8-10.8]), and TP53 alteration (yes vs no; 0.06 [0.03-0.10]) were significant factors associated with concordance.

Conclusions

Our results indicate that sharing the information of matched therapy, particularly for that with low evidence level, may be needed to improve the quality of treatment recommendations by MTBs.
