Prevention of Tumor Spread Due to Lung Cancer Surgery - Full Text View

ClinicalTrials.gov Identifier:	NCT00341380

Purpose

This study will investigate operative techniques to reduce the risk of tumor spread as a result of lung cancer surgery. Recent studies indicate that tumor cells may be released into the bloodstream due to handling of the lung during surgery, causing disease spread in patients whose tumor was previously confined to the lung. This study will examine whether the order in which the pulmonary vein (a vessel carrying blood from the lungs to the heart) and artery (vessel carrying blood from the heart to the lungs) are tied off during surgery affects the risk of tumor spread and disease recurrence.

Patients 18 years of age or older with operable Stage I or Stage II non-small cell lung cancer and no evidence of tumor spread beyond the lung may be eligible for this study. Candidates will be screened with a medical history, blood tests, chest X-ray, and possibly mediastinal evaluation. This test involves inserting a tube into the chest cavity to look for signs of disease spread beyond the lung.

All participants will undergo standard surgery for lung cancer. During the procedure, both the pulmonary artery and pulmonary vein are tied off; for this study, patients will be randomly assigned to have either the artery or the vein ligated first. Patients will be followed every 6 months for two years with blood tests and X-rays to look for disease recurrence.

Detailed Description:

The VALID study is designed to obtain information regarding factors associated with the risk of recurrence after resection of early stage Non-Small Cell Lung Cancer (NSCLC). Until recently, the only clearly identified prognostic factor was the stage of the disease. Recent development of sensitive molecular assays has provided a way to study the effect of circulating tumor cells on clinical outcome. Preliminary studies have shown that tumor cells detected by such means in lymph nodes or in bone marrow are associated with an increased risk of recurrence. Preliminary studies have also indicated that the level of circulating tumor cells in the blood stream is effected by intraoperative factors, i.e. the sequence of vessel ligation.

The main objective for this study is to investigate the influence of intraoperative sequence of vessel ligation and how this affects tumor recurrence and survival. In addition, we will also investigate the use of molecular assays to detect circulating tumor cells as a surrogate endpoint for the occurrence of distant metastases and/or death after surgery for NSCL. Several of these molecular markers have proven their value in case series but have not been rigorously tested for association with the clinical endpoints of interest, tumor recurrence and survival. We believe that this study may lead to important answers about how the spread of tumor cells occurs and if novel detection methods can be used to predict patient outcome.

Eligibility

Ages Eligible for Study:	19 Years and older
Genders Eligible for Study:	Both
Accepts Healthy Volunteers:	No

Criteria

INCLUSION CRITERIA:

Patients for this study will be identified through the Multidisciplinary Thoracic Oncology Clinic at UNC. Enrollment criteria for the study are: 1) Surgically respectable Stage I or II non-small cell lung carcinoma; 2) Negative mediastinal evaluation; 3) No contraindications for surgery; and 4) More than 18 years of age.

EXCLUSION CRITERIA:

Patients with prior carcinoma within 5 years (except basal cell carcinoma of the skin and superficial bladder cancer) will be excluded from the study. Patients who are enrolled based on clinical Stage I or II but are revised to higher Stage once the surgical specimens are examined will be excluded from statistical analysis.
