Surgical Treatment of Elderly Patients With cT1N0M0 Non-small Cell Lung Cancer Comparison Between Sublobar Resection and Lobectomy
- Conditions
- Non-small Cell Lung Cancer
- Interventions
- Procedure: VATSProcedure: Thoracotomy
- Registration Number
- NCT02360761
- Lead Sponsor
- Peking University People's Hospital
- Brief Summary
The role of sublobar resection(Wedge resection or anatomic segmentectomy) for small(≤ 2cm) early stage non-small cell lung cancer has been studied by Lung Cancer Study Group and is being studied by several ongoing trials. However, elderly patients(aged ≥70 years) in these trials is under-represented, as in most of the ongoing clinical trials. This study focuses on the elderly population of early stage lung cancer, and aims to investigate the outcome of lobectomy versus sublobar resection for peripheral stage I non-small cell lung cancer (NSCLC) in elderly patients.
- Detailed Description
This randomized trial is to the best of our knowledge the first one designed to compare sublobar resection and lobectomy for elderly patients, in order to address these open questions:In patients aged 70 years or older and with clinical stage T1N0M0 NSCLC, (1) whether sublobar resection can achieve similar disease-free survival compared to lobectomy, (2) whether sublobar resection can reduce the postoperative mortality and morbidity,(3) whether sublobar resection can reserve better pulmonary function and quality of life for elderly patients of NSCLC?
Recruitment & Eligibility
- Status
- UNKNOWN
- Sex
- All
- Target Recruitment
- 339
-
Aged 70 years or older
-
Preoperative criteria (contrast-enhanced Computed tomography scan)
- Suspected non-small cell lung cancer
- Clinical stage ⅠA, i.e. T1N0M0 (tumor diameter ≤3 cm, surrounded by visceral pleura, short-axis of lymph node <1 cm or cold lymph nodes on PET scan)
- The maximum diameter of consolidation of the maximum tumor diameter (consolidation/tumor ratio, C/T ratio) is no less than 0.5 in sub-solid lesions
- Eligible for sublobar resection with sufficient margin
-
Intraoperative criteria
- Histologically confirmed invasive NSCLC, i.e. NSCLC other than pre-invasive adenocarcinomas defined by The International Association for the Study of Lung Cancer (adenocarcinoma in situ, and minimally invasive adenocarcinoma)
- Pathological exclusion of suspected lymph nodes involvement
- Feasible to perform sublobar resection in terms of surgical margin requirement
-
General criteria
- Must sign informed consent by the patient or his/her entrusted party
- Must complete 4-year mortality index and comprehensive geriatric assessment(CGA) if necessary
- The physiological reservation can tolerate lobectomy
- Unable to comply with the study procedure
- Past thoracic surgery history, except for diagnostic thoracoscopy
- Malignant tumor history within the past 5 years, except for the following conditions: cured skin basal cell carcinoma, superficial bladder carcinoma, and uterine cervix cancer in situ
- Any active systemic diseases including uncontrolled hypertension, unstable angina pectoris, newly onset of angina pectoris within recent 3 months, congestive heart failure (class II or plus of New York Heart Association, NYHA), myocardial infarction within recent 6 months, severe disease in the need of medication such as arrhythmia, liver, renal or metabolic diseases
- Uncontrollable infections
- Coexisting small cell lung cancer
- Psychiatric diseases diagnosed
- Other circumstances which is deemed inappropriate for enrollment by the researchers

Group Intervention Description Lobectomy VATS Patients undergo lobectomy by thoracotomy or thoracoscopy/Video assisted thoracoscopic surgery(VATS). Sublobar resection Thoracotomy Patients undergo sublobar resection(wedge resection or anatomic segmentectomy) by thoracotomy or thoracoscopy/VATS. Sublobar resection VATS Patients undergo sublobar resection(wedge resection or anatomic segmentectomy) by thoracotomy or thoracoscopy/VATS. Lobectomy Thoracotomy Patients undergo lobectomy by thoracotomy or thoracoscopy/Video assisted thoracoscopic surgery(VATS).
- Primary Outcome Measures
Name Time Method Time To Disease free survival Event 3 years The time interval from randomization to the earliest onset of any of the following events: tumor recurrence, metastasis, or death caused by any reason.
- Secondary Outcome Measures
Name Time Method Percentage of Participants with Perioperative Complication and Death as a Measure of Safety. 1 months Perioperative complication is defined as the complication occurred after surgery and before discharge, or within 30 days postoperatively. Death cases during this period should be recorded as perioperative death.
Hospitalization time after surgery in Participants 1 months Defined as the time interval from the day of operation to discharge.
Intubation time after surgery in Participants 1 months Defined as the time interval from the day of operation to extubation.
Percentage of Participants With Local Recurrence and Metastasis Event 3 years The ratio of local recurrence and metastasis in 3 years from the day of randomization
Time To Overall survival Event 3 years The time interval from randomization to death from any cause.
Postoperative pulmonary function 3 years The Forced expiratory volume in one second and the forced vital capacity at 6-, 12- and 36-month post of the day of randomization.
Percentage of Participants With VATS procedure 1 month The ratio of video assisted thoracoscopic surgery in each group.
Scores on the quality of life questionaires 3 years The scores of the 6-, 12- and 36-month questionaire on quality of life post of the day of randomization.
