Study Evaluating the Efficacy of Loco-regional Anaesthesia PECS on Chronic Pain of a Mastectomy
- Conditions
- BreastcancerMastectomy
- Interventions
- Procedure: Loco-regional anaesthesia
- Registration Number
- NCT03023007
- Lead Sponsor
- Centre Oscar Lambret
- Brief Summary
A non-randomized, mono-centric, prospective interventional study that will assess the efficacy of the loco-regional anesthesia PECS on the rate of chronic pain, 6 month after a patient will have either received a mastectomy or a mastectomy associated with axillary nodes dissection, and/or a reconstruction by prosthesis.
- Detailed Description
The aim of this study is to assess the care given to treat breast cancer while the patient receives a total mastectomy. It is done by evaluating the technique of anesthesia PECS used during this procedure so that the rate of chronic pain can be measured 6 month after the operation.
As well as total mastectomy, patients are also eligible for an axillary lymph node dissection (ALND) and a reconstruction of the breast by prosthesis as options.
Other objectives of the study include:
* Evaluating the effectiveness of the PECS anesthesia technique on the trajectory of acute post-operative pain and on chronic pain after 12 month of the surgery
* Evaluating the type and intensity of the pain
* Evaluating the quality of life
* Study the link between chronic pain and the trajectory of acute pain.

- Primary Outcome Measures
Name Time Method Rate of chronic pain 6 month after surgery The rate of chronic pain will be assessed in percentage (%) based on the criteria of the International Association for the Study Pain (IASP) during an algology medical consultation.
- Secondary Outcome Measures
Name Time Method Rate of chronic pain 12 month after the surgery Assessed based on the criteria of the International Association for the Study Pain (IASP) collected via telephone call.
Side effects post-operative During the 3 days following the surgery All side effects (e.g. nausea, vomiting etc.) will be recorded, with its date, time, severity, relation with the treatment, treatment associated and evolution. The intensity of adverse events will be scored using the criteria from NCI-CTCAE version 4.0.
predictive factors of survival an average of 1 year Using the proportional hazards model.
Quality of life of the patient assessed with the QLQ-BR23 questionnaire an average of 1 year QLQ-BR23 (body image, perception of the future etc. and side effects)
Acute post-operative pain During the 3 days following the surgery A representation of the trajectory of pain in the 3 days will be drawn. This pain trajectory is defined as the kinetics of the average daily visual analog scale (VAS) score for 3 days.
Intensity of chronic pain 6 and 12 month after surgery The intensity of the pain will be recorded using the visual analog scale (VAS).
Depression assessed with the HADS questionnaire an average of 1 year HADS (Hospital Anxiety and Depression Scale) : to detect anxiety and depression
Quality of life of the patient assessed with the QLQ-C30 questionnaire an average of 1 year QLQ-C30 from the EORTC (quality of life in general, physical condition, limitations to activities, cognitive functions, emotional and social and symptoms occurrences related to cancer or the treatment)
Type of chronic pain 6 and 12 month after surgery The type of chronic pain will be determined using the DN4 score. The DN4 score is a form used for the diagnostic of neuropathic pain.
