  • Title: Adjuvant chemotherapy for non-small cell lung cancer.
    Author: Solomon B, Bunn PA.
    Journal: Cancer Invest; 2007 Jun; 25(4):217-25. PubMed ID: 17612931.
    Abstract:
    Nearly half of all patients who undergo surgical resection of localized non-small cell lung cancer (NSCLC) will develop and ultimately die of recurrent disease. The postoperative radiotherapy (PORT) meta-analysis showed adjuvant thoracic radiotherapy to have a detrimental effect on survival in this patient population. A meta-analysis of early trials of adjuvant chemotherapy by the Non-Small Cell Lung Cancer Collaborative Group showed that while chemotherapy with alkylating agents was also detrimental, chemotherapy with cisplatin-based adjuvant chemotherapy was associated with an improved hazard ratio for death (HR = 0.87), equating to a 5 percent survival benefit at 5 years. However, the result was not statistically significant (p = 0.08). Recently, results have been reported for several large Phase III trials of adjuvant chemotherapy which differed with respect to the stage of resected disease included, the type of chemotherapy used and the use of post-operative radiotherapy. Three trials (IALT, JBR 10, and ANITA) that utilized cisplatin-based doublets showed a significantly positive survival benefit of adjuvant chemotherapy in patients with Stage II-IIIA NSCLC. The magnitude of this benefit, which was suggested to be 4-5 percent at 5 years in the meta-analysis and by the IALT study, may be as large as 8-15 percent as indicated by more recent studies with modern platinum-based doublet chemotherapy. These data indicate that medically fit patients with resected Stage II-IIIA NSCLC should be offered adjuvant chemotherapy with a modern cisplatin-based doublet.
