About this study
Official title: Effect of a Perioperative Opioid Free Anaesthesia-Analgesia (OFA-A) Strategy on Surgical Stress Response and Immunomodulation in Elective VATS Lobectomy for NSCLC Lung Cancer: A Prospective Randomized Study
Lobectomy is a major, high-risk surgical procedure that in addition to one-lung ventilation (OLV) exerts a potent surgical stress response. An overwhelming immune cell recruitment may lead to excessive tissue damage, peripheral organ injury and immunoparesis. The effect of anesthesia on the immune system is modest, compared to the effects induced by major surgery. However, to an immunocompromised patient, due to cancer and/or other comorbidities, the immunosuppressive effects of anesthesia may increase the incidence of post-operative infections, morbidity, and mortality. Exogenous opioids have been correlated with immunosuppression, opioid-induced hyperalgesia, and respiratory depression, with deleterious outcomes. An Opioid-Free Anaesthesia-Analgesia (OFA-A) strategy is based on the administration of a variety of anaesthetic/analgesic and other pharmacological agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects. Our basic hypothesis is that the implementation of a perioperative multimodal OFA-A strategy, will lead to an attenuated surgical stress response and attenuated immunosuppression, compared to a conventional Opioid-Based Anaesthesia-Analgesia (OBA-A) strategy. The aforementioned effects, are presumed to be associated with equal or improved analgesia and decreased incidence of postoperative infections compared to a perioperative OBA-A technique.
Read the detailed description
Surgical manipulation and one lung ventilation (OLV) exert different and synergic effects to generate an inflammatory response during lung resection surgery. Surgery, such as lobectomies, often leads to severe immunosuppression that in turn can lead to infectious complications and sepsis. Both anesthesia-related and surgery-related perioperative measures may modulate the patient's immune response and lead to the activation of different components of the immune system. Anesthesia-induced activation, in particular of the adaptive immune system, may also induce persistent, postoperative immunosuppression. An overwhelming immune cell recruitment may lead to excessive tissue damage, peripheral organ injury and immunoparesis.
Opioid analgesia remains the corner stone of acute pain management in perioperative analgesic regimes. Opioid receptors are not only expressed in the central nervous system to regulate pain perception but also occur on immune and tumour cells. Exogenous opioid administration has been correlated with immunosuppression, opioid-induced hyperalgesia, and respiratory depression, with deleterious outcomes.
An Opioid-Free Anaesthesia-Analgesia (OFA-A) strategy is based on the administration of a variety of anaesthetic/analgesic and other pharmacological agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects where at least one factor causes inhibition of central sensitization and at least another factor inhibits the peripheral sensitization of the nervous system, as a response to painful surgical stimuli. This combination of factors has to have a synergistic or additive effect so that best analgesic effects can be achieved with the lowest possible dosage.
Our basic hypothesis is that a perioperative OFA-A strategy on cancer patients undergoing VATS lung surgery for tumour resection will be accompanied by abolished or attenuated immunosuppression. The additional potential clinical implication of a perioperative OFA-A strategy is the avoidance of the onco-proliferative side effects of both exogenous and endogenous opioids, released by cytokine-mediated immune cell activation. Inflammatory response inhibition is expected to reduce the possibility of acute and chronic post-operative pain developement, compared to a perioperative Opioid-Based Anaesthesia- Analgesia (OBA-A) technique. Additionally, the aforementioned inflammatory response inhibition is expected to lead to an overall reduction of overall postoperative pulmonary complications.

- Administration of a multimodal anaesthetic opioid-free strategy that includes pregabalin, ketamine, dexmedetomidine, lidocaine, dexamethasone, magnesium sulphate, paracetamol and dexketoprofen is expected to affect the inflammatory and stress response, measured by levels of inflammatory markers and haemodynamic stability, when compared to conventional opioid based techniques. An Opioid-Free Anaesthesia-Analgesia strategy, is expected to also lead to an attenuated immunosuppression, due to the avoidance of opioids, whose administration has been corelated with immunosuppressive effects. An overall decreased inflammatory and stress response as expressed by reduced levels of inflammatory biomarkers and hemodynamic stability, is expected to decrease peripheral and central sensitization, contributing to better postoperative analgesia.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Lobectomy is a major, high-risk surgical procedure that in addition to one-lung ventilation (OLV) exerts a potent surgical stress response. An overwhelming immune cell recruitment may lead to excessive tissue damage, peripheral organ injury and immunoparesis. The effect of anesthesia on the immune system is modest, compared to the effects induced by major surgery. However, to an immunocompromised patient, due to cancer and/or other comorbidities, the immunosuppressive effects of anesthesia may increase the incidence of post-operative infections, morbidity, and mortality. Exogenous opioids have been correlated with immunosuppression, opioid-induced hyperalgesia, and respiratory depression, with deleterious outcomes. An Opioid-Free Anaesthesia-Analgesia (OFA-A) strategy is based on the administration of a variety of anaesthetic/analgesic and other pharmacological agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects. Our basic hypothesis is that the implementation of a perioperative multimodal OFA-A strategy, will lead to an attenuated surgical stress response and attenuated immunosuppression, compared to a conventional Opioid-Based Anaesthesia-Analgesia (OBA-A) strategy. The aforementioned effects, are presumed to be associated with equal or improved analgesia and decreased incidence of postoperative infections compared to a perioperative OBA-A technique.
Detailed description
Surgical manipulation and one lung ventilation (OLV) exert different and synergic effects to generate an inflammatory response during lung resection surgery. Surgery, such as lobectomies, often leads to severe immunosuppression that in turn can lead to infectious complications and sepsis. Both anesthesia-related and surgery-related perioperative measures may modulate the patient's immune response and lead to the activation of different components of the immune system. Anesthesia-induced activation, in particular of the adaptive immune system, may also induce persistent, postoperative immunosuppression. An overwhelming immune cell recruitment may lead to excessive tissue damage, peripheral organ injury and immunoparesis.
Opioid analgesia remains the corner stone of acute pain management in perioperative analgesic regimes. Opioid receptors are not only expressed in the central nervous system to regulate pain perception but also occur on immune and tumour cells. Exogenous opioid administration has been correlated with immunosuppression, opioid-induced hyperalgesia, and respiratory depression, with deleterious outcomes.
An Opioid-Free Anaesthesia-Analgesia (OFA-A) strategy is based on the administration of a variety of anaesthetic/analgesic and other pharmacological agents with different mechanisms of action, including immunomodulating and anti-inflammatory effects where at least one factor causes inhibition of central sensitization and at least another factor inhibits the peripheral sensitization of the nervous system, as a response to painful surgical stimuli. This combination of factors has to have a synergistic or additive effect so that best analgesic effects can be achieved with the lowest possible dosage.
Our basic hypothesis is that a perioperative OFA-A strategy on cancer patients undergoing VATS lung surgery for tumour resection will be accompanied by abolished or attenuated immunosuppression. The additional potential clinical implication of a perioperative OFA-A strategy is the avoidance of the onco-proliferative side effects of both exogenous and endogenous opioids, released by cytokine-mediated immune cell activation. Inflammatory response inhibition is expected to reduce the possibility of acute and chronic post-operative pain developement, compared to a perioperative Opioid-Based Anaesthesia- Analgesia (OBA-A) technique. Additionally, the aforementioned inflammatory response inhibition is expected to lead to an overall reduction of overall postoperative pulmonary complications.

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 2 inclusion and 12 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: status not confirmed, as of the sponsor's last update on 29 Dec 2021. 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 Greece. 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.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Periklis Vasilos, MD (00306978702023, p.vassilos@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Neutrophil to Lymphocyte ratio (NLR) (time frame: Preoperatively). The study lists 101 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05172739, which also lists 13 linked publications.
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 29 Dec 2021.
