tumor microenvironment TME
The cellular and molecular ecosystem surrounding cancer cells, including immune cells, stromal cells, blood vessels, and signaling molecules that influence tumor behavior and treatment response.
next-generation sequencing
High-throughput DNA sequencing technology enabling rapid analysis of multiple genes, exomes, or whole genomes simultaneo...
NGS
Next-generation sequencing technology used for comprehensive genomic analysis in cancer diagnosis.
oncogene addiction
A cancer cell's dependence on continued oncogene activity for survival and proliferation, creating therapeutic vulnerabi...
oncometabolite
A metabolic compound that accumulates due to cancer-associated enzyme defects and contributes to tumorigenesis through e...
oncotype score
A numerical recurrence score derived from a multigene expression assay used to guide treatment decisions in breast cance...
organoid drug screening
Testing therapeutic agents on three-dimensional tumor models derived from patient samples to predict treatment response.
PARP inhibitor
A targeted therapy that blocks PARP enzymes, preventing DNA repair in cancer cells with BRCA mutations.
pathway analysis report
A molecular diagnostic document detailing disrupted cellular pathways and corresponding therapeutic opportunities.
pathway-directed therapy
Treatment approach targeting specific molecular signaling cascades rather than individual gene mutations.
PD-L1 expression
Quantitative measurement of programmed death-ligand 1 protein on tumor cells, used to predict immunotherapy response.
PDL1
Programmed death-ligand 1, a protein biomarker used to predict immunotherapy response.
pharmacodynamic biomarker
A measurable biological indicator that demonstrates a drug's effect on its target or downstream pathways, used to monito...
pharmacogenomic interaction report
A document detailing how genetic variants affect drug metabolism, efficacy, and toxicity in cancer treatment.
polymerase epsilon mutation
A specific DNA repair gene alteration associated with hypermutated tumors and enhanced immunotherapy response.
precision medicine report
A clinical document summarizing molecular findings and therapeutic recommendations based on tumor profiling.

precision oncology workflow
Standardized process integrating molecular testing, data analysis, and treatment selection for individualized cancer car...
resistance mutation
A genetic alteration that enables cancer cells to survive and proliferate despite targeted therapy, leading to treatment...
somatic mutation
A genetic alteration that occurs in non-reproductive cells during an individual's lifetime and is not inherited by offsp...
splice site variant
A genetic alteration affecting RNA splicing signals that can disrupt normal mRNA processing, potentially leading to aber...
synthetic lethality
A therapeutic strategy where combined inhibition of two genes or pathways is lethal to cancer cells but tolerable to nor...
targetable alteration
Genetic variant with available FDA-approved or investigational therapies that specifically address the molecular abnorma...
targetable pathway
A cellular signaling cascade with molecular components that can be effectively inhibited or modulated by approved or inv...
