The following is a summary of “Research progress and application of single-cell sequencing in head and neck malignant tumors,” published in the November 2023 Issue of Oncology by Qu al.

Single-cell sequencing (SCS) represents an innovative technology that isolates numerous cells from an organism and meticulously scrutinizes the genetic material expressed within each cell, employing high-throughput sequencing techniques. Unlike conventional bulk sequencing methods that solely offer aggregate data from cell populations without specificity at the individual cell level, SCS distinguishes itself by discerning gene sequences and expression alterations within individual cells. This approach sheds light on disparities in genetic material and protein content among cells, elucidating the intricate dynamics within the tumor microenvironment. In the realm of head and neck malignancies, SCS serves as a potent tool, delving into the singular biological aspects of individual cells and furnishing a foundational framework for understanding the onset and progression of these cancers.

By probing the single-cell biological landscape, SCS significantly contributed to unraveling the underlying mechanisms fueling head and neck malignancies. Its ability to discern nuanced genetic variations and expression disparities between cells facilitates a comprehensive comprehension of the intricate interplay among these malignancies. Moreover, it establishes a robust theoretical underpinning for the clinical diagnosis and therapeutic interventions targeting head and neck tumors.

This article aims to carefully outline the latest advancements and applications of SCS in malignant head and neck tumors. It will delve into the multifaceted benefits and potential implications offered by SCS technology, expounding upon its role in deciphering the intricacies of tumor biology at the individual cellular level. Through a systematic exploration of these developments, this study highlights the transformative potential of SCS in shaping the landscape of diagnosis and therapeutic strategies for head and neck malignancies.
