Lymph Node Removal in Treating Patients With Stage I or Stage II Non-Small Cell Lung Cancer

2014-08-27 03:58:32 | BioPortfolio


RATIONALE: Surgical removal of all lymph nodes in the chest may kill cancer cells that have spread from tumors in the lung. It is not yet known whether complete removal of all lymph nodes in the chest is more effective than removal of selected lymph nodes in treating patients who have stage I or stage II non-small cell lung cancer.

PURPOSE: Randomized phase III trial to compare the effectiveness of complete removal of all lymph nodes in the chest with that of selected removal of lymph nodes during lung cancer surgery in treating patients who have stage I or stage II non-small cell lung cancer.



- Compare whether a complete mediastinal lymph node dissection versus mediastinal lymph node sampling improves overall survival of patients with N0 or non-hilar N1 non-small cell lung cancer undergoing resection.

- Compare these two methods with reference to identification of occult mediastinal lymph node involvement.

- Compare the effect of these two methods on operative time and duration of postoperative complications, including chest tube drainage and length of hospitalization for these patients.

- Compare the effect of these two methods on local recurrence free survival and local regional recurrence free survival of these patients.

OUTLINE: This is a randomized study.

Patients undergo lymph node sampling from multiple sites inside the chest. Patients with negative lymph nodes are randomized to 1 of 2 treatment arms.

- Arm I (Mediastinal Lymph Node Sampling): No more lymph nodes are removed. Patients undergo pulmonary resection.

- Arm II (Mediastinal Lymph Node Dissection): Patients undergo removal of nearly all of the lymph nodes from the central part of the chest between the lungs, followed by pulmonary resection.

Patients are followed at 4, 6, 8, 12, 18, 24, and 36 months and then annually thereafter until death.

PROJECTED ACCRUAL: A total of 1,000 patients (500 per arm) will be accrued for this study over 5 years.

Medical and Biotech [MESH] Definitions

Tumors or cancer of the LUNG.

Malignant neoplasm arising from the epithelium of the BRONCHI. It represents a large group of epithelial lung malignancies which can be divided into two clinical groups: SMALL CELL LUNG CANCER and NON-SMALL-CELL LUNG CARCINOMA.

That portion of the stomach remaining after gastric surgery, usually gastrectomy or gastroenterostomy for cancer of the stomach or peptic ulcer. It is a common site of cancer referred to as stump cancer or carcinoma of the gastric stump.

Nuclear phosphoprotein encoded by the p53 gene (GENES, P53) whose normal function is to control CELL PROLIFERATION and APOPTOSIS. A mutant or absent p53 protein has been found in LEUKEMIA; OSTEOSARCOMA; LUNG CANCER; and COLORECTAL CANCER.

Therapeutic practices which are not currently considered an integral part of conventional allopathic medical practice. They may lack biomedical explanations but as they become better researched some (PHYSICAL THERAPY MODALITIES; DIET; ACUPUNCTURE) become widely accepted whereas others (humors, radium therapy) quietly fade away, yet are important historical footnotes. Therapies are termed as Complementary when used in addition to conventional treatments and as Alternative when used instead of conventional treatment.
