Abstract:
Tumour heterogeneity is one of the main characteristics of cancer and can be categorised into inter- or intratumour heterogeneity. This heterogeneity has been revealed as one of the key causes of treatment failure and relapse. Precision oncology is an emerging field that seeks to design tailored treatments for each cancer patient according to epidemiological, clinical and omics data. This discipline relies on bioinformatics tools designed to compute scores to prioritise available drugs, with the aim of helping clinicians in treatment selection. In this review, we describe the current approaches for therapy selection depending on which type of tumour heterogeneity is being targeted and the available next-generation sequencing data. We cover intertumour heterogeneity studies and individual treatment selection using genomics variants, expression data or multi-omics strategies. We also describe intratumour dissection through clonal inference and single-cell transcriptomics, in each case providing bioinformatics tools for tailored treatment selection. Finally, we discuss how these therapy selection workflows could be integrated into the clinical practice.
Insights
Tumour heterogeneity drives cancer treatment failure. This review explores bioinformatics tools for precision oncology, using omics data to select tailored therapies based on inter- and intratumour heterogeneity.
Area of Science:
- Oncology
- Bioinformatics
- Genomics
Background:
- Tumour heterogeneity, encompassing inter- and intratumour variations, is a primary driver of cancer treatment failure and relapse.
- Precision oncology aims to personalize cancer treatment by integrating diverse patient data, including clinical, epidemiological, and omics information.
- Bioinformatics tools are crucial for analyzing complex cancer data to guide therapeutic decisions.
Purpose of the Study:
- To review current bioinformatics approaches for selecting cancer therapies.
- To address how different types of tumour heterogeneity (inter- and intratumour) influence therapy selection strategies.
- To discuss the integration of these data-driven workflows into clinical practice.
Main Methods:
- Review of existing literature on tumour heterogeneity and precision oncology.
- Analysis of bioinformatics tools for analyzing genomics, expression, and multi-omics data.
- Examination of methods for clonal inference and single-cell transcriptomics for intratumour heterogeneity.
Main Results:
- Different bioinformatics strategies are employed for intertumour heterogeneity (e.g., genomics variants, expression data, multi-omics) and intratumour heterogeneity (e.g., clonal inference, single-cell transcriptomics).
- These methods provide computational scores to prioritize drugs for tailored treatment selection.
- The review highlights specific bioinformatics tools applicable to each approach.
Conclusions:
- Bioinformatics tools are essential for navigating tumour heterogeneity in precision oncology.
