Abstract The Oral and Salivary Cancer Biology Program at National Institute of Dental and Craniofacial Research (NIDCR) supports research activities that improve early detection and treatment of cancers of the oral cavity, pharynx, and salivary glands. We promote basic science research on the regulatory pathways and transformation process of pre-cancerous lesions to primary and metastatic tumors, as well as translational science activities to develop novel technologies and therapeutics for the diagnosis, prognosis, and treatment of cancers. NIDCR and National Cancer Institute (NCI) have established long-term collaborations to promote and co-manage awards funded through The Immuno-Oncology Translational Network (IOTN) of the Cancer Moonshot program, Specialized Programs of Research Excellence (SPOREs), and Early Detection Research Network (EDRN) program. NIDCR and NCI have co-developed Notice of Special Interest (NOSI) and Request for Application (RFA) on Advancing Head and Neck Cancer Early Detection Research (AHEAD), which co-funded seven research projects to discover and develop molecular signatures of early detection and diagnosis of HPV positive and negative head and neck cancer (HNC). To further strengthen NIDCR and NCI collaboration, we jointly organized the symposium to promote HNC early detection and biomarker identification at the American Head and Neck Society (AHNS) 11th International Conference on Head and Neck Cancer in July 2023. In addition, NIDCR has organized a symposium to promote HNC research at the 2024 annual meeting of American Association for Dental, Oral, and Craniofacial Research (AADOCR) to celebrate the 75th anniversary of NIDCR. This AADOCR symposium will feature the collaboration between NIDCR with NCI in the Cancer Moonshot program focusing on immunoprevention and immunotherapy, HNC early detection and biomarker research in AHEAD and EDRN, and investigation of HPV positive and negative HNC and clinical translational research under SPORE. At this 2024 AACR annual meeting, NIDCR and NCI program directors will present the collaborations and funding opportunities between NIDCR and NCI, focusing on early cancer detections and biomarker discovery and validation. Collaboration between NIDCR with NCI provides a unique opportunity to promote basic, translational, and clinical research in advancing HNC early detection to benefit cancer patients.
