Study Evaluating the Efficacy of Loco-regional Anaesthesia PECS on Chronic Pain of a Mastectomy

Not Applicable
Completed
Conditions
Breastcancer
Mastectomy
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
NameTimeMethod
Rate of chronic pain6 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
NameTimeMethod
Rate of chronic pain12 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-operativeDuring 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 survivalan average of 1 year

Using the proportional hazards model.

Quality of life of the patient assessed with the QLQ-BR23 questionnairean average of 1 year

QLQ-BR23 (body image, perception of the future etc. and side effects)

Acute post-operative painDuring 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 pain6 and 12 month after surgery

The intensity of the pain will be recorded using the visual analog scale (VAS).

Depression assessed with the HADS questionnairean 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 questionnairean 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 pain6 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.
