PI3K/AKT/mTOR signaling transduction pathway and targeted therapies in cancer

Molecular Cancer, Год журнала: 2023, Номер 22(1)

Опубликована: Авг. 18, 2023

Abstract The PI3K/AKT/mTOR (PAM) signaling pathway is a highly conserved signal transduction network in eukaryotic cells that promotes cell survival, growth, and cycle progression. Growth factor signalling to transcription factors the PAM axis regulated by multiple cross-interactions with several other pathways, dysregulation of can predispose cancer development. most frequently activated human often implicated resistance anticancer therapies. Dysfunction components this such as hyperactivity PI3K, loss function PTEN, gain-of-function AKT, are notorious drivers treatment disease progression cancer. In review we highlight major dysregulations cancer, discuss results AKT mTOR inhibitors monotherapy co-administation antineoplastic agents clinical trials strategy for overcoming resistance. Finally, mechanisms targeted therapies, including immunology immunotherapies also discussed.

Abemaciclib plus a nonsteroidal aromatase inhibitor as initial therapy for HR+, HER2− advanced breast cancer: final overall survival results of MONARCH 3

Highlights•This phase III trial evaluated abemaciclib + NSAI versus placebo as initial therapy for HR+, HER2− ABC.•Addition of to an resulted in numerically longer OS; however, statistical significance was not reached.•Absolute improvement median OS clinically meaningful (ITT: 13.1 months; sVD: 14.9 months).•The previously demonstrated PFS benefit with the addition sustained (median 14.3 delayed subsequent receipt chemotherapy 16.1 months).AbstractBackgroundIn MONARCH 2, fulvestrant significantly improved both progression-free survival (PFS) and overall (OS) patients hormone receptor-positive (HR+), human epidermal growth factor receptor 2-negative (HER2−) advanced breast cancer (ABC) disease progression on prior endocrine therapy.

Inavolisib-Based Therapy in PIK3CA -Mutated Advanced Breast Cancer

New England Journal of Medicine, Год журнала: 2024, Номер 391(17), С. 1584 - 1596

BackgroundInavolisib is a highly potent and selective inhibitor of the alpha isoform p110 catalytic subunit phosphatidylinositol 3-kinase complex (encoded by PIK3CA) that also promotes degradation mutated p110α. Inavolisib plus palbociclib–fulvestrant has shown synergistic activity in preclinical models promising antitumor early-phase trials.MethodsIn phase 3, double-blind, randomized trial, we compared first-line inavolisib (at an oral dose 9 mg once daily) (inavolisib group) with placebo (placebo patients PIK3CA-mutated, hormone receptor–positive, human epidermal growth factor receptor 2 (HER2)–negative locally advanced or metastatic breast cancer who had relapse during within 12 months after completion adjuvant endocrine therapy.

6th and 7th International consensus guidelines for the management of advanced breast cancer (ABC guidelines 6 and 7)

The Breast, Год журнала: 2024, Номер 76, С. 103756 - 103756

Опубликована: Май 28, 2024

This manuscript describes the Advanced Breast Cancer (ABC) international consensus guidelines updated at last two ABC conferences (ABC 6 in 2021, virtual, and 7 2023, Lisbon, Portugal), organized by Global Alliance. It provides main recommendations on how to best manage patients with advanced breast cancer (inoperable locally or metastatic), of all subtypes, as well palliative supportive care. These are based available evidence expert opinion when a higher level is lacking. Each guideline accompanied (LoE), grade recommendation (GoR) percentage reached conferences. Updated diagnostic treatment algorithms also provided. The represent management options for living globally, assuming accessibility therapies. Their adaptation (i.e. resource-stratified guidelines) often needed settings where access care limited.
