The immune checkpoint inhibitor (ICI) pembrolizumab combined with chemotherapy is the current standard of care in TNBC patients with stage II and III. Monotherapy with ICIs has not been comprehensively assessed in the neoadjuvant setting in TNBC patients, given unfavorable results in metastatic trials. ICIs, however, have been tested in the window of opportunity (WOO) before surgery or standard chemotherapy-based neoadjuvant treatment. The WOO design is well suited to assess an ICI alone or in combination with other ICIs, targeted therapy, radiotherapy or cryotherapy, and measure their pharmacodynamic and clinical effect in this treatment-naive population. Some patients show a good response to ICIs in WOO studies. Biomarkers like tumor-infiltrating lymphocytes, programmed death ligand-1, and interferon-γ signature may predict activity and may identify patients likely to benefit from ICIs. Moreover, an increase in tumor-infiltrating lymphocytes, programmed death ligand-1 expression or T cell receptor expansion following administration of ICIs in the WOO setting could potentially inform of immunotherapy benefit, which would allow tailoring further treatment. This article reviews WOO trials that assessed immunotherapy in the early-stage TNBC population, and how these results could be translated to test de-escalation strategies of neoadjuvant chemotherapy and immunotherapy without compromising a patient's prognosis. http://hdl.handle.net/11351/12184 Mama - Càncer - Tractament Mama - Càncer - Immunoteràpia DISEASES::Neoplasms::Neoplasms by Site::Breast Neoplasms::Triple Negative Breast Neoplasms Other subheadings::Other subheadings::Other subheadings::/drug therapy CHEMICALS AND DRUGS::Chemical Actions and Uses::Pharmacologic Actions::Therapeutic Uses::Antineoplastic Agents::Antineoplastic Agents, Immunological Other subheadings::Other subheadings::/therapeutic use ENFERMEDADES::neoplasias::neoplasias por localización::neoplasias de la mama::neoplasias de mama triple negativos Otros calificadores::Otros calificadores::Otros calificadores::/farmacoterapia COMPUESTOS QUÍMICOS Y DROGAS::acciones y usos químicos::acciones farmacológicas::usos terapéuticos::antineoplásicos::inmunoterapia antineoplásica Otros calificadores::Otros calificadores::/uso terapéutico Window of opportunity trials with immune checkpoint inhibitors in triple-negative breast cancer
