BACKGROUND: A Joint Expert Panel recently published guidelines for adjuvant cisplatin-based chemotherapy, recommending routine use in patients with completely resected stage II (T1-2N1 and T3N0) non-small-cell lung cancer (NSCLC). However, these two tumor subgroups should be considered as different entities. While the efficacy of adjuvant chemotherapy has been established in patients with T1-2N1 NSCLC, its benefit in patients with T3N0 tumor remains questionable. MATERIAL AND METHODS: We performed an extensive review of the literature using the Joint Expert Panel guidelines as a start point. Altogether, we identified 76 potentially relevant articles. Basing on inclusion and exclusion criteria, 23 of the 76 articles were eventually included in this review. RESULTS: After careful evaluation of the selected articles, we found no information on the effect of adjuvant chemotherapy in patients with T3N0 NSCLC. DISCUSSION: In the absence of evidence-based data, we recommend that the lack of information on the efficacy of adjuvant chemotherapy for T3N0 tumors be discussed with patients and propose chemotherapy as an individual option. While the efficacy of adjuvant chemotherapy will be difficult to assess prospectively through a large randomized clinical trial, a pooled-analysis of the existing data would quickly and with a limited effort provide a preliminary answer.
