Sublobar Wedge Resection or Stereotactic Radiotherapy Treatment of High-risk Patients With Early-stage Lung Cancer
Sponsor: Aarhus University Hospital
Summary
In low-risk patients with stage I non-small cell lung cancer (NSCLC) surgical treatment with an anatomical resection is currently the standard of care. For medically inoperable patients with stage I NSCLC, radiation therapy is currently the standard treatment. The latest generation of radiation therapy modalities is Stereotactic Body Radiation Therapy (SBRT). In high-risk patients, minimal invasive surgery in terms of sublobar resection (wedge resection) with lymph node sampling is currently the recommended treatment approach for these patients, even though the evidence is limited. Additionally, SBRT is an alternative treatment option but the use in these patients is also based on weak evidence. So, it is highly warranted to compare these two treatment options in this group of patients in a randomized, controlled trial where selection bias can be eliminated. It is the specific aim of this study to provide such a trial allowing an evidence-based approach when deciding between surgery and SBRT as treatment for NSCLC in high-risk patients. The STRADOS study (STereotactic RADiotherapy Or Surgery) is an open randomized, controlled national multicenter study in which high-risk patients with stage I non-small-cell lung cancer (NSCLC) are randomized to receive either surgical treatment with minimal invasive wedge resection with lymph node sampling, or SBRT. The overall purpose of the study is to investigate the disease-free survival (DFS) after surgical treatment when compared to SBRT. The primary endpoint is DFS after 3 years. Secondary endpoint is quality of life after 1, 3, 6, 12 and 36 months. Tertiary endpoints are overall survival (OS) after 3 and 5 years; DFS after 5 years; re-admission adverse events and complications after 1, 3, 6, 12 and 36 months; health-care related costs within 12 and 36 months; PRO data - other than quality of life (QoL) (health condition, symptoms and functional level) after 1, 3, 6, 12 and 36 months and lung function test after 12 month.

Conditions
Interventions
Stereotactic radiation therapy intervention
The SBRT planning technique is based on recommendations from the Advisory Committee on Radiation Oncology Practice (ACROP) guideline and the ICRU report 91: Prescribing, Recording and Reporting of Stereotactic Treatments with Small Photon Beams as implemented in the recommendations from the Radiotherapy Committee of Danish Oncology Lung Cancer Group. Planning should be guided by respiratory guided CT scans
Surgical intervention
Patients who are randomized to have surgery undergo a SWR via a minimal approach (VATS or RATS) during general anesthesia. Pre- and postoperative care and treatment is offered in accordance with local department guidelines. The surgery must be performed or supervised by a specialist in thoracic surgery. The operation is performed with the patient in lateral recumbent position. The surgeon decides the number of ports (1-4), and local analgesic is applied at the incision sites and/or as a nerve block. Additional pain management is registered and performed according to the local practice at the individual department. At the end of surgery, a chest tube is inserted in pleura through one of the ports, and the tube is connected to suction at levels decided by the treating surgeon. Patients in which minimal surgery is converted to thoracotomy are included in an intention-to-treat analysis.
