Breast cancer [ICD-11: 2C60]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Epigenetic Alteration of DNA, RNA or Protein (EADR)

Key Molecule: NT-3 growth factor receptor (TrkC) [1]

• Molecule Alteration: Missense mutation; p.G623R (c.1867G>A)
• Resistant Disease: Breast adenocarcinoma [ICD-11: 2C60.1]

• In Vitro Model: Ba/F3 cells; Colon; Homo sapiens (Human); CVCL_0161
• Experiment for Molecule Alteration: Fluorescence in situ hybridization assay; Mutational profiling of actionable cancer targets assay
• Experiment for Drug Resistance: Promega assay
• Mechanism Description: Recurrent gene rearrangements such as ETV6-NTRK3 are a critical mechanism of oncogenic activation for the neurotrophic tyrosine receptor kinase genes, NTRK1, NTRK2, and NTRK3, in human malignancies. Fusion of the intact tyrosine kinase domain of NTRK1, NTRK2, or NTRK3 with a variety of upstream partners results in dysregulated activation of several biochemical signaling pathways that promote oncogenic initiation and growth.

Breast lactating adenoma [ICD-11: 2F30]

Drug Resistance Data Categorized by Their Corresponding Mechanisms

Aberration of the Drug's Therapeutic Target (ADTT)

Key Molecule: NT-3 growth factor receptor (TrkC) [1]

• Molecule Alteration: Missense mutation; p.G623R
• Resistant Disease: Mammary analogue secretory carcinoma [ICD-11: 2F30.1]
• Experimental Note: Identified from the Human Clinical Data
• Experiment for Molecule Alteration: Whole genome sequencing assay
• Mechanism Description: A dramatic and durable response was achieved with entrectinib in this patient, followed by acquired resistance that correlated with the appearance of a novel NTRK3 G623R mutation. Investigation into the structural impact of the G623R point mutation revealed a potential mechanism of relative resistance to entrectinib and other Trk inhibitors. The NTRK3 G623R mutation creates steric hindrance that functionally reduces the binding of entrectinib with mutant TrkC.
