Pain and loss of function are intimately associated with the reaction of the nervous system to neural damage. A lesion to the somatosensory nervous system caused by mechanical trauma, metabolic disease, neurotoxic chemicals, infection or tumor invasion may give rise to neuropathic pain. Neuropathic pain affects around 8% of the population and may negatively impact the individual's quality of life; moreover, the condition leads to significant costs to the healthcare system and society. Not all subjects with such a lesion develop neuropathic pain, and those who do develop neuropathic pain have varying degrees of symptom severity, impact and outcomes and may respond unpredictably to treatment.
The interaction between genetics and environmental and clinical factors in a susceptible individual most likely contribute to the variation in pain prevalence and severity. A better understanding of the exact nature of these risk factors and their interactions will ultimately improve the patients' health, both in terms of recognizing patients at risk and identifying new treatment modalities.
Genetic, neurophysiological and psychological factors all influence the risk of developing persistent pain. It is therefore possible to describe a genetic, neurophysiological and psychological profile, in particular in patients experiencing neuropathic pain after surgery and/or neurotoxic chemotherapy.

- Procedure: Thoracic surgery for lung cancer
Lung cancer resection performed via Video-assisted thoracoscopic surgery (VATS) and/or thoracotomy, including lobectomy, bilobectomy, pneumonectomy, resection of the tracheobronchial bifurcation, wedge resection, sleeve resection and combinations hereof.
- Chronic Neuropathic Pain, Postoperative [ Time Frame: 12 months after surgery ]Neuropathic pain grading system, Finnerup et al. 2016 will be used.
- Chronic Chemotherapy-induced Peripheral Neuropathy [ Time Frame: 12 months after surgery ]For case definition of neuropathy, Tesfaye et al. 2010 will be used.
- Chronic Chemotherapy-induced Neuropathic Pain [ Time Frame: 12 months after surgery ]Neuropathic pain grading system, Finnerup et al. 2016 will be used.
- Acute Postoperative Pain [ Time Frame: 0-5 days after surgery ]Rest and movement-evoked postoperative pain measured on an 11-point NRS
- Area of peri-incisional hyperalgesia [ Time Frame: 0-5 days after surgery ]Quantification of peri-incisional hyperalgesia - area and worst pin-prick pain intensity is assessed with a 5.88 monofilament
