Surgical approach to non-small cell lung cancer stage I and II.
No patient with a potentially curable lung cancer should be denied the opportunity for a curative resection. Solitary pulmonary nodules should be approached as though they were malignant until proven otherwise, either by definitive histologic or extremely convincing circumstantial clinical evidence. Consequently, thoracotomy should be performed, assuming that the patient is physiologically able, if cancer cannot be definitely excluded. The evaluation of patients with synchronous lung nodules is complex owing to the possible causes of the two nodules but should be pursued because of its important effect on therapeutic outcome. The major factor influencing survival is the extent of the tumor at the time of resection. When metastatic lymph nodes are found at the time of surgery, regardless of the location, the survival rate is significantly lower. Lobectomy for patients with stage I disease is usually sufficient treatment, but when the tumor is large (exceeding 4 cm) or centrally located or when hilar lymph nodes are involved, a pneumonectomy must be considered in order to eradicate local disease. Those patients with N1 disease can obtain improved survival when resection is combined with adjuvant radiation and chemotherapy.
