About this study
Official title: Effects of Epidural Anesthesia-analgesia on Long-term Survival in Patients After Lung Cancer Surgery: A Randomized Controlled Trial
Available studies suggest that regional anesthesia-analgesia may decrease the occurrence of recurrence/metastasis in patients after cancer surgery. However, evidences from prospective studies are still lacking. The purpose of this randomized controlled trial is to investigate the effect of epidural anesthesia-analgesia on recurrence-free survival in patients undergoing lung cancer surgery.
Read the detailed description
Lung cancer is increasing and is the leading cause of cancer death. Surgical resection is the mainstay of treatment for early stage non-small cell lung cancer. However, long-term survival after lung cancer surgery is far from optimal, and cancer recurrence or metastasis is the main reason leading to cancer death in these patients.
The development of cancer recurrence/metastasis largely depends on the balance between tumor-promoting factors and immune function of the body. Studies showed that surgical manipulation releases cancer cells into circulation; and stress response induced by surgery inhibits the cell-mediated immunity. In addition, volatile anesthetics and opioids may also aggravate immunosuppression and potentially worsen long-term outcome. On the other hand, regional anesthesia can blunt surgical stress and reduce anesthetic consumption. These effects may help to preserve immune function and reduce recurrence/metastasis. However, existing evidences are insufficient to draw conclusion in this topic.
The purpose of this randomized controlled trial is to test the hypothesize that regional anesthesia-analgesia may reduce recurrence/metastasis and improve long-term survival in patients after lung cancer surgery.

Questions about this trial
What is this clinical trial studying?
A study testing General anesthesia alone and Combined epidural-general anesthesia in people with Lung Cancer and Thoracic Surgery, run by Peking University First Hospital at 1 site in China.
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 3 inclusion and 7 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: finished, as of the sponsor's last update on 27 Aug 2020. 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 China. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Recurrence-free survival after surgery. (time frame: Up to 4 years after surgery.). 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 NCT02801409, which also lists 42 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 27 Aug 2020.
