Final results of KEYNOTE-355: Randomized, double-blind, phase 3 study of pembrolizumab + chemotherapy vs placebo + chemotherapy for previously untreated locally recurrent inoperable or metastatic triple-negative breast cancer.

The phase II TOPACIO trial showed promising results (ORR 21%) with a combination of niraparib and pembrolizumab in a small cohort of TNBC of whom about half were germline carriers84; it remains unclear how much of the responsiveness was purely attributable to PARPi in gBRCA-associated tumors in that trial.

When a sign is not denoted before a number, it usually means it's positive. Adding pembrolizumab to several chemotherapy regimens (nab-paclitaxel, paclitaxel, or gemcitabine/carboplatin) in KEYNOTE 355 improved PFS and OS in chemo-naive-PDL1+ TNBC patients, defined as CPS ≥ 10% PDL1-expession by the Dako 22C3 assay, including patients who relapsed early after adjuvant chemotherapy92.

In no trial has an impact of immunotherapy in PDL1-negative metastatic patients been observed, and the best chemotherapy combination with ICI remains an open question. Google Scholar. How best to define immune activation is a work in progress; current approaches include the presence of TILs, expression of the programmed death-ligand 1 (PDL1) protein, immune gene signatures, RNA expression of individual immune genes, and immune cell clonality (Tcells and Bcells) studies.

Abstract. Tutt, A. et al. The introduction into clinical practice of RNA-based assays that subtype BC by intrinsic biology and prognosis is well established for clinical decision-making in early ER+BC, and recent studies suggest potential value in metastatic, and in clinically HER2-positive disease15,16,17,18,19. Molecular portraits of human breast tumours. J. 38, 423–433 (2020). More detailed confirmation of BC heterogeneity has come from multiple efforts to examine DNA, RNA, microRNA, and protein expression patterns through cross-platform analyses such as The Cancer Genome Atlas and METABRIC10,11. Triple-negative breast cancer (TNBC) cells do not have estrogen or progesterone receptors, and they do not make any or much of the HER2 protein. 31 (Suppl. Han, H. et al. Oncol. 32, 1148–1156 (2021). The umbrella term “TNBC” represents a spectrum of tumors that are disparate both from a tumor and from a microenvironmental standpoint. Hoadley, K. A. et al. Regulatory T cells, M2 macrophages, and immature DCs can conversely create an immune escape tumor microenvironment that correlates with worse prognosis29 (Fig. Triple-negative breast cancer. 2021;7(7):1016-1023. doi:10.1001/jamaoncol.2021.1254, Siegel SD, Brooks MM, Lynch SM, et al. 385, 2336–2347 (2021). Research suggests that there are more than 280,000 new cases each year in the United States. The risk of relapse from TNBC has decreased with improved overall treatment and better chemotherapy regimens (Fig. It accounts for 10–15% of incident breast cancers and carries the worst prognosis.

In the phase 3 NeoTRIPaPDL1 trial of neoadjuvant chemotherapy plus atezolizumab or placebo, both cell features such as PDL1 expression as well as a high degree of spatial interaction between epithelial and microenvironmental cells appeared predictive of atezolizumab benefit44. 7, 302–321 (2017). 379, 753–763 (2018).

Is there a role for immunotherapy in HER2-positive breast cancer? A recent study using laser capture microdissection gene expression profiles classified four different immune-tumor microenvironment (TME) subtypes42, including the “inflamed” subtype, characterized by CD8+ T cells distributed in both epithelial and stromal tumor compartments and high immune gene expression, compared with the less immune-activated margin and stroma restricted-TME subtypes, and the least immune-activated group, the “immune desert”, in which there were few CD8+ T cells at all, and only at the margin42. Cortes, J. et al. Clin. Cancer Res. Cancer Res. Weiss, A. et al.

ADC antibody drug conjugate; PARPi: poly-ADP ribose polymerase inhibitors; HRD homologous recombination deficiency; AR androgen receptors. Investig. Oncol. For example, low grade adenoid cystic and secretory TNBC carry better prognosis and, unless high risk clinical features exist, may not require systemic chemotherapy2. TPC in both trials did not include standard first-line drugs, particularly platinums, but regardless these lower-toxicity non-chemotherapy options are hugely valuable both in TNBC and non-TNBC gBRCA-associated breast cancer. KEYNOTE 522 was a large practice-changing trial that was unusual in that it was powered for both pCR and EFS endpoints. Triple negative breast cancer risks and prevention.

Within each clinical subtype there are multiple molecular subtypes. About 13 out of 100,000 women in the United States are diagnosed with TNBC each year. Only those with gBRCA1/2 were particularly sensitive to the platinum agent, with 6.8 months of median PFS (vs 4.4m with docetaxel)21. IPATunity130: A pivotal randomized phase III trial evaluating ipatasertib (IPAT) + paclitaxel (PAC) for PIK3CA/AKT1/PTEN -altered advanced triple-negative (TN) or hormone receptor-positive HER2-negative (HR+/HER2–) breast cancer (BC). Other studies were designed to target the EGFR signaling pathway that is almost universally activated in the BL-subtype, however an early trial, TBCRC 001, failed to demonstrate an effect of adding the anti-EGFR antibody cetuximab to carboplatin in TNBC patients79, and another randomized phase II trial demonstrated only a modest 10% improvement in ORR with the addition of cetuximab to cisplatin80. Traina, T. A. et al. Moreover, higher pCR rates were observed in patients with high TILs in a trial adding carboplatin to a neoadjuvant anthracycline and taxane regimen versus the non-carboplatin, suggesting that TILs might predict benefit to specific chemotherapy agents, although this interaction was not significant in the TNBC subset33. The participants in the highest weight quartile had a 79% increased risk of TNBC compared with those in the lowest quartile. Mol. The tank has 30,000 liters, and 1,000 liters are taken out every day. Correlative analysis of overall survival by intrinsic subtype across the MONALEESA-2, -3, and -7 studies of ribociclib + endocrine therapy in patients with HR+/HER2− advanced breast cancer.

Given that the name TNBC illustrates its lack of specifically targeted and effective therapy, we look forward to being able to retire the name in favor of a group of targetable entities within what is now called “TNBC”. Increased prevalence of dihydropyrimidine dehydrogenase deficiency in African-Americans compared with Caucasians. New ideas are emerging that may allow tumor targeting (e.g., epigenetic modulators preventing reprogramming, AR targeting), prevent immune evasion (e.g., DDR1 antibodies, combinatorial immunotherapy) and maybe even prevent TNBC.

Lehmann and colleagues initially described seven subtypes of TNBC, based on specific clusters of gene expression potentially useful for targeted therapies. Article Oncologist 18, 123–133 (2013). Using clinical assays, TNBC is human epidermal growth factor receptor 2 (HER2) negative and has <1% expression of estrogen receptors (ER) and progesterone receptors (PR) by immunostaining. J. Clin.
