Surgery Versus Stereotactic Body Radiation Therapy for Stage up to IA2 (T1a or T1b) Non-small Cell Lung Cancer

Overview

The primary objective of this study is disease free survival rate at 5 years in stage IA2 (T1aN0M0 or T1bN0M0 only) non-small cell lung cancer (NSCLC) patients treated either by surgery or stereotactic body radiation therapy (SBRT).

Study Type

  • Study Type: Interventional
  • Study Design
    • Allocation: Non-Randomized
    • Intervention Model: Crossover Assignment
    • Primary Purpose: Treatment
    • Masking: None (Open Label)
  • Study Primary Completion Date: March 2020

Detailed Description

Today, the best medical literature available confirms that surgery is superior to radiation therapy in the treatment of the early stage lung cancer. However, good emerging data demonstrates potential equality between these two treatments. Two major international studies have tried to compare both treatments but have failed to complete the study because of the lack of patients accrual. We chose to design a trial in which patients will be part of a shared decision making process in selecting the treatment modality.

Patients with early stage lung cancer, that can undergo surgical treatment will be offered SBRT, and in conjunction with the pulmonologist will decide which treatment they prefer. We intend to complete the recruitment of patients within 02 years, then follow-up for 5 more years to collect data.

Interventions

  • Procedure: Anatomical Segmentectomy, Lobectomy or Bilobectomy
    • Lung Cancer Anatomical Resection
  • Radiation: Stereotactic Body Radiation Therapy
    • SBRT treatment. 48Gy in 4 sessions for peripheral lesions and 50Gy in 5 sessions for central lesions.

Arms, Groups and Cohorts

  • Active Comparator: Surgery
    • Patients that will undergo surgery (anatomical segmentectomy, lobectomy or bilobectomy) as primary lung cancer treatment
  • Active Comparator: SBRT (Stereotactic Body Radiation Therapy)
    • Patients that will undergo SBRT as primary lung cancer treatment

Clinical Trial Outcome Measures

Primary Measures

  • Disease free survival
    • Time Frame: 5 years
    • To compare the disease free survival of patients with Stage up to IA2 (T1aN0M0 or T1bN0M0) NSCLC managed either by SBRT or surgery.

Secondary Measures

  • Overall Survival
    • Time Frame: 5 years
    • Overall survival rate at 5 years in both arms
  • Level of morbidity
    • Time Frame: 5 years
    • Level of morbidity in both arms (CTCAE 4.0 – common toxicity criteria)
  • Level of efficacy in the SBRT arm
    • Time Frame: 5 years
    • Level of efficacy in the SBRT arm (RECIST 1.1)
  • QOL assessment
    • Time Frame: 5 years
    • QOL assessment with SF36 questionnaire (pre and post treatment) in both arms
  • FEV1 and DLCO decline at 1-year post-treatment in both arms
    • Time Frame: 1 year
    • FEV1 or DLCO decline at 1-year post-treatment in both arms
  • Health economic evaluation in both arms
    • Time Frame: 5 years
    • Health economic evaluation in both arms

Participating in This Clinical Trial
