Vision Statement

The AACR brings together people who have a united goal to cure cancer. Its global footprint realized through the Annual Meeting, thematic conferences, workshops, journals, grants, and scholarships has successfully fostered scientific advances spanning fundamental research to clinical trials. Collaborative initiatives such as AACR Project GENIE have enabled genomic and clinical data sharing on an international scale. Yet there are many valuable nonclinical and clinical datasets comprising positive or negative study results that need to be published and shared for greater learning. The AACR must continue to be a pioneer leading these efforts, catalyzing the scientific community worldwide to continue its quest for openness, innovation, inspiration, and impact. With its vast and diverse membership residing in 124 countries, the AACR has access to the brightest minds across borders and continents to tackle the complexities and challenges related to the prevention, diagnosis, and treatment of cancer.

As a physician-scientist in the field of anticancer drug development and precision medicine, I understand the importance of a dynamic engagement and exchange between basic, translational, and clinical research. Seminal discoveries in cancer biology, technical advances in molecular characterization, and emerging insights in the immune system, which are garnered at the bench by basic scientists, must be expeditiously translated to the bedside to improve patient outcomes. Translational and correlative science, clinical trials, and patient-oriented research, in turn, yield the critical knowledge needed to generate new biological hypotheses. Data science and artificial intelligence offer novel computational tools to analyze and deconvolute high-density information. The AACR must act as a nexus in this circle of integrative team science, connecting researchers, investigators, policymakers, funders, patients, caregivers, advocates, and survivors, to ensure that the most relevant questions are urgently addressed to improve cancer care and outcomes. Pivotal landmark legislation, such as the half-century old National Cancer Act and the more recent 21st Century Cures Act, has injected substantive federal funding to support cancer research. As one of the most authoritative voices in oncology, the AACR must continue its remit to advocate for moonshot efforts such as these, as well as for reliable annual NIH/NCI budget increases. The AACR will persist as a strong champion to raise awareness from the philanthropic community to provide sustained research support for scientists at all career levels.

Training and mentorship of scientists and investigators are critical to shape the future of cancer research, and educational efforts must target groups as early as high school and university undergraduate students to attract them to this rewarding field. The unmet needs and gaps of early, mid-career, and senior scientists are different; the AACR must reach out to all groups, irrespective of gender, race, and background, to understand how best to empower their careers, enhance research output, increase job satisfaction, and maintain work-life balance. Opportunities such as seed and bridge grants need to be expanded to encourage scientific scholarship. Leadership development courses and workshops should be developed by the AACR for individuals with the greatest potential to excel to be next generation stars. The most powerful weapons in the battle against cancer are the minds of researchers; thus the AACR must invest in its mission to educate. It is the collective wisdom of the scientific community that will ultimately bring cures to this disease.
