«Adjuvant chemotherapy should be offered to patients with resected stage II and III [I,A] and can be considered in patients with resected stage IB disease and a primary tumor > 4cm[II,B]. Pre-existing comorbidities, time from surgery and post-operative recovery need to be taken into account in this decision in a multidisciplinary tumor board[v,a]. For adjuvant chemotherapy, a two-drug combination with cisplatin is preferable [I,A]. In randomised studies, the attempted cumulative cisplatin dose was up to 300mg/m², delivered in 3 to 4 cycles. The most frequently studied regimen is cisplatin-vinorelbine. In the current stage of knowledge, the choice of adjuvant chemotherapy should not be guided by molecular analysis such as, e.g. ERCC-1 or mutation testing[iv,b]»

In view of the equivalence of neo-adjuvant and adjuvant chemotherapy for overall survival, the consistent results and broad evidence base support adjuvant chemotherapy as the timing of choice[i, A].

Authors suggest that one definitive local treatment modality combined with neoadjuvant chemotherapy is adequate to treat resectable stage IIIA/N2 non-small-cell lung cancer. PlessM, et al. Lancet 2015

incidental IIIA(N2)(unforeseen N2) Recommendation: If, despite adequate mediastinal staging procedures, N2 disease is only documented intra-operatively, surgery should be followed by adjuvant chemotherapy [I, A]. In case of complete resection, addition of post-operative radiotherapy is not routinely recommended, but may be an option following individual risk assessment[v, C].

Potentially resectable IIIA(N2) disease(pre-operative diagnosis of IIIA-N2) several options: induction CT followed by surgery, induction CT/RT followed by surgery, or concurrent definitive CT/RT [I, A]. No recommendation can yet be made; however, an experienced multidisciplinary team is of paramount importance in any complex multi-modality treatment strategy decision. If induction chemotherapy alone is given preoperatively, postoperative radiotherapy is not standard treatment but may be an option based on critical evaluation of locoregional relapse risks[iv, C].

In potentially resectable superior sulcus tumours, concurrent chemoradiotherapy induction followed by definitive surgery is the treatment of choice [III, A]. The same strategy may be applied for potentially resectable T3 or T4 central tumours in highly selected cases and experienced centres[iii, B]. In both situations, surgery should be carriedoutwithin4weeksaftertheendofradiotherapy[iii,b].
