About this study

Official title: Investigation of the Effect of Erector Spinae Plane Block on Systemic Immuno-Inflammatory Index in Breast Cancer Surgery: A Prospective Randomized Controlled Study

Erector spinae plane block (ESPB) is a novel interfascial block technique first described by Forero in 2016. It has been reported to be effective in various clinical indications. In ESPB, local anesthetic is injected between the deep fascia of the erector spinae muscle and the transverse process of the vertebra, allowing cephalocaudal spread along the erector spinae muscle. The goal of the injection is to provide sensory blockade by affecting the anterior rami of the spinal nerves in the region.

ESPB has been used during breast and axillary lymph node surgeries to manage postoperative pain. In addition to tumor cells, immune and inflammatory cells such as neutrophils, platelets, and lymphocytes contribute to the dissemination and invasion of tumor cells into the peripheral circulation. Noninvasive biomarkers such as serum inflammatory markers are increasingly valued for their simplicity and predictive potential. Platelets have been shown to facilitate epithelial-mesenchymal transition of tumor cells; neutrophils support tumor adhesion via growth factors such as VEGF and proteases; lymphocytes play a role in modulating the host immune response to malignancy.

The systemic immune-inflammatory index (SII), calculated as (platelet count × neutrophil count) / lymphocyte count, is a relatively new composite marker that reflects immune and inflammatory responses. It has been evaluated as a prognostic biomarker in several cancer-related studies.

Postoperative pain and surgical stress activate systemic inflammatory responses. ESPB is performed as part of postoperative analgesia in patients undergoing breast cancer surgery under general anesthesia, based on voluntary participation. The aim of this study is to evaluate the effect of ESPB on postoperative SII levels in comparison to other analgesia modalities.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Systemic Immune-Inflammation Index (SII)

    Systemic immune-inflammation index (SII) will be calculated using the formula:

    SII = (Platelet count × Neutrophil count) / Lymphocyte count. This index will be used to evaluate the effect of erector spinae plane block (ESPB) on postoperative systemic inflammation in patients undergoing breast cancer surgery.

    Measured: 6 hours postoperatively

Secondary outcomes (1)
  1. Postoperative Pain Score

    Postoperative pain will be assessed using a Visual Analog Scale (VAS) ranging from 0 (no pain) to 10 (worst imaginable pain). Pain scores will be recorded at rest and during movement at predefined time points to evaluate the analgesic effectiveness of erector spinae plane block (ESPB).

    Measured: At 0, 2, 4, and 6 hours postoperatively

Questions about this trial

What is this clinical trial studying?

A study testing Erector spinae plane block in people with Erector Spinae Plane Block and Systemic Immune-inflammatory Index, run by Namik Kemal University at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 May 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Systemic Immune-Inflammation Index (SII) (time frame: 6 hours postoperatively). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06954324, which also lists 3 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 May 2025.
