Targeting Stress-Driven Inflammatory and Angiogenic Pathways With Brief ACT to Enhance Neoadjuvant Chemotherapy Response in Locally Advanced Breast Cancer
Effect of Brief Acceptance and Commitment Therapy on Neoadjuvant Chemotherapy Response in Locally Advanced Breast Cancer Through Modulation of Inflammatory and Angiogenic Biomarkers.
This clinical trial aims to learn whether a brief psychological therapy called Brief Acceptance and Commitment Therapy (Brief-ACT) can improve the effectiveness of neoadjuvant chemotherapy in patients with locally advanced breast cancer. It will also examine how this therapy affects stress levels and certain blood markers related to inflammation and tumor growth.
The main questions this study aims to answer are:
Does Brief-ACT improve the rate of pathological complete response (pCR) after chemotherapy? Does Brief-ACT reduce levels of inflammatory and angiogenic biomarkers such as C-reactive protein (CRP), interleukin-6 (IL-6), neutrophil-to-lymphocyte ratio (NLR), and vascular endothelial growth factor (VEGF)? Does Brief-ACT reduce psychological stress in patients undergoing chemotherapy?
Researchers will compare patients who receive Brief-ACT in addition to standard chemotherapy with those who receive standard chemotherapy alone to see if there are differences in treatment response, stress levels, and biomarker levels.
Participants will:
Receive neoadjuvant chemotherapy according to standard treatment protocols Be assigned to receive Brief-ACT sessions or no additional psychological intervention Attend regular clinic visits for treatment and monitoring Provide blood samples at specific time points for laboratory analysis Complete questionnaires to assess psychological stress

Descrizione dettagliata
Breast cancer patients with locally advanced disease frequently experience substantial psychological distress during treatment, which has been associated with adverse biological effects. Chronic psychological stress may activate neuroendocrine pathways, particularly the hypothalamic-pituitary-adrenal (HPA) axis, leading to increased production of pro-inflammatory cytokines and angiogenic factors. These biological alterations, including elevated levels of interleukin-6 (IL-6), C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), and vascular endothelial growth factor (VEGF), are thought to contribute to tumor progression and resistance to chemotherapy.
Emerging evidence suggests that psychological interventions may influence these biological pathways. Acceptance and Commitment Therapy (ACT), particularly in its brief format (Brief-ACT), has been shown to improve psychological flexibility and reduce stress. However, its potential role in modulating inflammatory and angiogenic biomarkers and improving chemotherapy response in breast cancer patients remains insufficiently explored.
This study is designed as a randomized controlled trial to evaluate the effect of Brief-ACT on treatment response in patients with locally advanced breast cancer undergoing neoadjuvant chemotherapy. The intervention is delivered alongside standard chemotherapy and focuses on enhancing psychological flexibility through core ACT processes, including acceptance, cognitive defusion, present-moment awareness, and value-based action.
In addition to evaluating clinical response, this study investigates the potential biological mechanisms underlying the effect of psychological intervention. Serial measurements of inflammatory and angiogenic biomarkers are performed to assess whether changes in psychological stress are associated with modulation of these pathways. This integrative approach aims to bridge psychological and biological domains in cancer treatment.
The findings of this study are expected to provide evidence on whether a structured psychological intervention can serve as an adjunctive strategy to improve chemotherapy outcomes through modulation of stress-related biological processes. If effective, this approach may support the integration of psychosocial care into standard oncological treatment to enhance both clinical and biological outcomes.

Sperimentale: Brief-ACT + Neoadjuvant Chemotherapy
Participants in this arm receive standard neoadjuvant chemotherapy in combination with Brief Acceptance and Commitment Therapy (Brief-ACT).
The Brief-ACT intervention is delivered in structured sessions during the course of chemotherapy and focuses on enhancing psychological flexibility through core ACT processes, including acceptance, cognitive defusion, present-moment awareness, and value-based action.

Brief Acceptance and Commitment Therapy (Brief-ACT) is a structured psychological intervention delivered during the course of neoadjuvant chemotherapy.
The intervention focuses on enhancing psychological flexibility through core ACT processes, including acceptance, cognitive defusion, present-moment awareness, self-as-context, values clarification, and committed action.
Sessions are delivered in a brief format tailored to the clinical setting and are integrated into routine oncology care during chemotherapy cycles.
Standard neoadjuvant chemotherapy regimen administered according to institutional protocols for locally advanced breast cancer.

Comparatore attivo: Standard Counseling + Neoadjuvant Chemotherapy
Participants in this arm receive standard neoadjuvant chemotherapy along with standard counseling provided as part of routine clinical care.
The counseling serves as an attention-control condition to account for non-specific therapeutic effects, without incorporating structured Brief-ACT components.

Standard neoadjuvant chemotherapy regimen administered according to institutional protocols for locally advanced breast cancer.
Altri nomi:
Standard counseling consists of routine supportive communication provided as part of standard clinical care during neoadjuvant chemotherapy.
This includes general emotional support, basic health education, and non-directive discussion without the use of structured psychotherapeutic techniques such as Acceptance and Commitment Therapy.
This intervention serves as an attention-control condition.
