Description

Summary

This randomized phase III trial studies surgery and internal radiation therapy to see how well they work compared to surgery alone in treating patients with stage I non-small cell lung cancer. Surgery may be an effective treatment for non-small cell lung cancer. Internal radiation uses radioactive material placed directly into or near a tumor to kill tumor cells. It is not yet known whether surgery and internal radiation therapy are more effective than surgery alone in treating non-small cell lung cancer.

Official Title

A Randomized Phase III Study of Sublobar Resection Versus Sublobar Resection Plus Brachytherapy in High Risk Patients With Non-Small Cell Lung Cancer (NSCLC), 3cm or Smaller

Details

PRIMARY OBJECTIVES:

  1. To ascertain whether patients treated by sublobar resection (SR) + brachytherhapy (BX) have longer time to local recurrence as compared to the patients treated by SR (local recurrence includes recurrence within the same lobe or hilum [N1 nodes], or progression at the staple line after treatment effects such as scarring have subsided).

SECONDARY OBJECTIVES:

  1. To compare procedure specific morbidity and mortality between study arms. II. To compare overall survival and failure-free survival between study arms. III. To assess freedom from regional or distant recurrence. IV. To assess the effect of histological or cytologic positive resection margins on time to local recurrence.
  2. To determine the effect of brachytherapy on quality of life (QoL). VI. To determine the effect of brachytherapy on pulmonary function.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients undergo open or thoracoscopic sublobar resection comprising either a wedge resection or anatomical segmentectomy.

ARM II: Patients undergo surgery as in arm I. Patients also undergo intraoperative brachytherapy comprising iodine I 125 implant at the resection margin.

After completion of study treatment, patients are followed at 3, 6, 12, 18, 24, 30, and 36 months and then yearly for 2 years.

  • Diffusing capacity of the lungs for carbon monoxide (DLCO) =< 50% predicted
  • Minor criteria
  • Age >= 75
  • FEV1 51-60% predicted
  • DLCO 51-60% predicted
  • Pulmonary hypertension (defined as a pulmonary artery systolic pressure greater than 40 mmHg) as estimated by echocardiography or right heart catheterization
  • Poor left ventricular function (defined as an ejection fraction of 40% or less)
  • Resting or exercise partial pressure of oxygen (pO2) =< 55 mm Hg or peripheral capillary oxygen saturation (SpO2) =< 88%

  • PART II: INTRA-OPERATIVE CRITERIA (REGISTRATION)
  • Patient must have biopsy-proven NSCLC
  • Patient must have all suspicious mediastinal lymph nodes (> 1 cm short-axis dimension on CT scan or positive on positron emission tomography [PET] scan) assessed by one of the following methods to confirm negative involvement with NSCLC (mediastinoscopy,endo-esophageal ultrasound guided needle aspiration, CT-guided, video-assisted thoracoscopic or open lymph node biopsy)
