Abstract

Candida albicans (C. albicans) represents one of the most prevalent opportunistic fungal pathogens in cancer patients. Although the association between C. albicans and cancer has been recognized for decades, the causal relationship, whether C. albicans infection is a consequence of cancer or a direct contributor to cancer development-remains a subject of intensive investigation. Recently, the complex interplay between microbes and cancer has garnered significant attention within the scientific community, with growing interest in elucidating the underlying molecular mechanisms. This review systematically examines the biological characteristics of C. albicans, its multifaceted interactions with the host, and its relationship with the intestinal microbiota. Additionally, it provides a comprehensive analysis of the association between C. albicans and the development of various malignancies, with particular emphasis on digestive tract cancers. The review also identifies critical knowledge gaps and apparent contradictions in existing research, highlighting potential avenues for breakthroughs that will advance the efficient and accurate screening, diagnosis, and treatment of cancer.

Keywords: Candida albicans; Cancer progression; Immune evasion; Inflammatory response; Tumor microenvironment

Core Tip: This review explores the role of Candida albicans (C. albicans), an opportunistic fungus, in cancer progression, particularly in digestive tract malignancies. It examines the interactions between C. albicans and the host, highlighting its relationship with the intestinal microbiota. The study also addresses the ongoing debate about whether C. albicans contributes to cancer development or is merely a complication of cancer. By identifying gaps in current research, this review seeks to open new directions for cancer screening, diagnosis, and treatment.
