Consensus conference: multimodality management of early- and intermediate-stage non-small cell lung cancer.

Surgery is the mainstay of treatment in early- and intermediate-stage non-small cell lung cancer (NSCLC), yet recurrences are frequent. Studies have documented the benefits of chemotherapy administered after resection, but a number of questions remain regarding how overall outcomes can be further improved. To provide the oncology community with direction on these issues, a consensus conference of leading experts in the NSCLC field was held at the Fifth Annual Atlanta Lung Cancer Symposium on October 25-27, 2007. The available scientific literature is presented and when such literature is lacking, clinical experience is provided to support the following conclusions. Preoperative staging should be done in accordance with the National Comprehensive Cancer Network guidelines, but endoscopic fine needle aspiration of enlarged mediastinal nodes can be used, and if histology is positive for malignancy, mediastinoscopy can be avoided. Neoadjuvant systemic therapy is not generally recommended but can be considered to downstage an unresectable patient. There is currently no role for preoperative radiation or chemoradiation. Adjuvant systemic therapy is not recommended for stage IA and IB patients; however, adverse prognostic factors are acceptable reasons to consider adjuvant systemic therapy in the latter. Adjuvant systemic therapy is recommended for stage IIA, IIB, and IIIA patients, consistent with recent American Society of Clinical Oncology guidelines. A cisplatin-based regimen should be started within 60 days after surgery, but if relatively contraindicated, carboplatin is an acceptable alternative. Adjuvant radiation therapy is not recommended for N0 and N1 patients, but is used in N2 patients to decrease local recurrence.
