Abstract
There have been many attempts to develop effective postoperative adjuvant therapy in patients with resected lung cancer. Metastatic disease is the commonest site of first recurrence. In squamous cell carcinoma local failure is another major problem and in adenocarcinoma brain metastases are frequent. There is evidence to suggest that radiotherapy can prevent local recurrence but does not appear to impact on survival. Response rates to chemotherapy alone and chemo-radiotherapy with prolongation of disease-free survival have been encouraging in locally advanced (resected stage II, III) disease when treated postoperatively. Results of clinical trials using immunotherapy or chemotherapy in early stage disease have been disappointing. Several prospective randomized studies by the Lung Cancer Study Group were undertaken to assess the merits of various adjuvant treatments and are presented.
