    摘要 胃腸恶性肿瘤给我国人民的生命健康带来了严重的危害。中医学具有以人为本、整体调节的特点在我国胃肠肿瘤的防治体系中占据一席之地。当代中医形成了以健脾为核心的防治理念，但各医家对脾虚内涵的理解尚不统一，应用方药差异较大，制约中医药研究质量的提高和未来的发展。本团队多年来从脾虚论治结直肠癌的临床和科研工作取得了较好的成效，并与国内多家单位一起，围绕脾虚在胃肠肿瘤领域开展循证研究工作。现结合文献和团队多年来的实践，提出瘤之成因与治疗造就胃肠恶性肿瘤病机以脾虚为主，遵循以脾虚为本、邪实自内外而生、蕴化癌毒、病久及肾的病机演变规律，正虚、邪实、癌毒是中医认识其病机的3个层面，同时兼有胃癌易于阳化、肠癌易于寒化的特点。最后从证治规律、临床试验、生物机制3个方面列举当前已有的相关研究实践作为验证。对胃肠肿瘤脾虚理论的探索起到了抛砖引玉的作用，旨在促进中医肿瘤防治理论的创新，为更高质量的研究提供理论支撑。
