Trial summary

Approximately 55,000 cases of breast cancer are diagnosed in Italy every year and the first-line therapy for carcinoma in situ, stage I, II and IIIA is surgical removal of the tumour. The incidence of chronic pain after breast cancer surgery is confirmed around 30%. Read more about this study

About this study

Official title: Impact of Loco-regional Anesthesia Techniques on Chronic Post-surgery in Breast Oncological Surgery: a Prospective Multicenter Observational Study

Approximately 55,000 cases of breast cancer are diagnosed in Italy every year and the first-line therapy for carcinoma in situ, stage I, II and IIIA is surgical removal of the tumour. The incidence of chronic pain after breast cancer surgery is confirmed around 30%. This study aims to evaluate the impact of loco-regional anesthesia techniques in the context of multimodal analgesia in the prevention of chronic pain post-oncological breast surgery

Read the detailed description

Approximately 55,000 cases of breast cancer are diagnosed in Italy every year and the first-line therapy for carcinoma in situ, stage I, II and IIIA is surgical removal of the tumour. The incidence of chronic pain after breast cancer surgery is confirmed around 30%.Persistent postsurgical pain, defined in the ICD-11 as pain that develops or increases in intensity after a surgical procedure or tissue damage and persists beyond the healing process for at least 3 months after the initial event and is considered a complication of surgery.

Several pharmacological and non-pharmacological interventions have been proposed for the prevention of the development of this complication of surgical interventions, including the intraoperative use of local anesthesia techniques in the context of multimodal analgesia.

The purpose of this multicenter prospective observational study is to evaluate, through the propensity score methodology, how much the use of loco-regional anesthesia techniques can improve the outcome, in terms of the development of chronic post-surgical pain, of patients undergoing to oncological breast surgery

What is being measured

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

  1. Incidence of chronic postoperative pain after major breast surgery

    Incidence of chronic post-surgical pain after major breast surgery (definition: pain that persists at least 3 months after surgery; pain that was not present before surgery or that has different characteristics from pain before surgery or that has increased intensity than before the operation; the pain is localized in the area of the surgical site or in its radiation; other possible causes of pain are excluded)

    Measured: 6 - 12 months

Secondary outcomes (5)
  1. Acute post-operative pain

    Acute postoperative pain. NRS Numerical Rating Scale (0-10; 0 =better 10= worse outcome)

    Measured: 2, 6, 12 and 24 hours

  2. Chronic post-operative pain

    Pain both at rest and on mobilization month3, month6, month9 and month12 after surgery. Numerical Rating Scale (0-10; 0 =better 10= worse outcome)

    Measured: 3,6,9,12 months) at rest and on mobilization

  3. Quality of life score

    Quality of recovery score-15 (QoR 15; scale 0-150; 0=better 150=worse outcome)

    Measured: Quality of recovery score (QoR 15)

  4. Remifentanyl

    Intraoperative use of remifentanil. Intraoperative quantitative use of remifentanyl (total micrograms; the lesser the better)

    Measured: Intraoperative

  5. Opioid

    Postoperative opioid use. (opioid oral morphine milligram equivalent (MME); the lesser the better)

    Measured: hour2, hour 6, hour 12 and hour 24 after surgery

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer, run by Niguarda Hospital at 1 site in Italy.

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 11 inclusion and 0 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: enrolling by invitation, as of the sponsor's last update on 16 Apr 2026. 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 Italy. 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?

This study is still under way. Results are not available in the source record yet.

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?

Incidence of chronic postoperative pain after major breast surgery (time frame: 6 - 12 months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 16 Apr 2026.
