    Circulating tumour DNA characterisation of invasive lobular carcinoma in patients with metastatic breast cancer
    (Elsevier, 2022) Davis, Andrew A.; Gerratana, Lorenzo; Clifton, Katherine; Medford, Arielle J.; Velimirovic, Marko; Hensing, Whitney L.; Bucheit, Leslie; Shah, Ami N.; D’Amico, Paolo; Reduzzi, Carolina; Zhang, Qiang; Dai, Charles S.; Denault, Elyssa N.; Bagegni, Nusayba A.; Opyrchal, Mateusz; Ademuyiwa, Foluso O.; Bose, Ron; Gradishar, William J.; Behdad, Amir; Ma, Cynthia X.; Bardia, Aditya; Cristofanilli, Massimo; Medicine, School of Medicine
    Background: Limited data exist to characterise molecular differences in circulating tumour DNA (ctDNA) for patients with invasive lobular carcinoma (ILC). We analysed metastatic breast cancer patients with ctDNA testing to assess genomic differences among patients with ILC, invasive ductal carcinoma (IDC), and mixed histology. Methods: We retrospectively analysed 980 clinically annotated patients (121 ILC, 792 IDC, and 67 mixed histology) from three academic centers with ctDNA evaluation by Guardant360™. Single nucleotide variations (SNVs), copy number variations (CNVs), and oncogenic pathways were compared across histologies. Findings: ILC was significantly associated with HR+ HER2 negative and HER2 low. SNVs were higher in patients with ILC compared to IDC or mixed histology (Mann Whitney U test, P < 0.05). In multivariable analysis, HR+ HER2 negative ILC was significantly associated with mutations in CDH1 (odds ratio (OR) 9.4, [95% CI 3.3-27.2]), ERBB2 (OR 3.6, [95% confidence interval (CI) 1.6-8.2]), and PTEN (OR 2.5, [95% CI 1.05-5.8]) genes. CDH1 mutations were not present in the mixed histology cohort. Mutations in the PI3K pathway genes (OR 1.76 95% CI [1.18-2.64]) were more common in patients with ILC. In an independent cohort of nearly 7000 metastatic breast cancer patients, CDH1 was significantly co-mutated with targetable alterations (PIK3CA, ERBB2) and mutations associated with endocrine resistance (ARID1A, NF1, RB1, ESR1, FGFR2) (Benjamini-Hochberg Procedure, all q < 0.05). Interpretation: Evaluation of ctDNA revealed differences in pathogenic alterations and oncogenic pathways across breast cancer histologies with implications for histologic classification and precision medicine treatment.
