Summary
The objective of these cohorts is to detect potential genetic, neurophysiological psychological and cognitive risk factors for the development of chronic postsurgical pain including neuropathic pain.
Detailed description
This new study will enroll patients undergoing mastectomy or thoracotomy for cancer. They will be three cohorts : * one prospective cohort constituted of women undergoing breast surgery in René Huguenin Hospital (Saint Cloud) and followed for up to one year after surgery. * another cross sectional cohort constituted of patient association (Seintinelle) including women operated up to 2 years previously from breast surgery. * One prospective cohort constituted of women or men undergoing thoracotomy in Foch hospital (Suresnes) and followed for up to one year after surgery. The main objectives of these cohorts will be to detect potential genetic, neurophysiological, psychological and cognitive risk factors for the development of chronic postsurgical neuropathic pain. These patients will questioned about demographics, age, sex, body mass index. A large neuropsychological and psychological battery of tests will be conducted. Sensory function will assessed using quantitative sensory testing. Biological samples will analyse potential genetic factors in the development of neuropathic pain after surgery. Conditioned pain modulation, threshold tracking and quantitative sensory testing will also be assessed in subgroup of patients. The prospective cohort will be assessed before surgery then 3, 6 and 12 months after surgery. The cross sectional cohort will be assessed during one to two visits in hospital.
