pubmed-article:12449726pubmed:abstractTextLung cancer is the most frequent cause of cancer death in the United States. The pattern of regional lymph node involvement is a major prognostic factor in a patient with nonsmall cell lung cancer. The accuracy of information obtained about the lymph node status of lung cancer patients can be potentially increased by sentinel node lymphatic mapping. This technique has been well studied in melanoma and breast cancer. It may be useful in increasing the detection of micrometastases and in decreasing the morbidity from complete mediastinal lymphadenectomy. We report an animal pilot study of pulmonary lymphatic mapping. The aim of our study was to gain experience in the surgical techniques for pulmonary sentinel node lymphatic mapping in an animal model prior to its application in humans. Technetium sulfur colloid and isosulfan blue dye were injected into different lobes of the lung followed by attempts to identify the sentinel node draining that specific portion of the lung. Technetium sulfur colloid identified the sentinel node in five of six dogs within 20 min after the radiotracer was injected into the lung parenchyma. Isosulfan blue dye identified the sentinel node in three of six dogs within 5 min. Both the agents are potentially useful, but we found greater technical ease in identifying the sentinel node with technetium sulfur colloid. Two single-institution pilot studies in humans have been performed. A multicentered study to validate and further refine this technique is necessary. Advanced pathologic techniques such as immunohistochemistry and reverse transcriptase-polymerase chain reaction can be used to enhance the accuracy of staging. This may facilitate proper application of novel therapeutic strategies to improve the current dismal prognosis of this disease.lld:pubmed
