A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether the addition of postoperative radiotherapy (PORT) to adjuvant chemotherapy offers any benefit in patients undergoing curative resection for non-small cell lung cancer found to harbour mediastinal lymphadenopathy. A total of 77 papers were identified using the reported search, of which 11 represented the best evidence to answer the clinical question. Only studies reporting on survival data of patients receiving adjuvant chemotherapy with and without PORT were included in this analysis. The authors, date, journal, country, study type, population, outcomes and key results are tabulated. Six studies reported a statistically significant positive impact of PORT on long-term or disease-free survival (DFS) (P = 0.048-0.0001). Five more studies found no difference in terms of survival between patients receiving and not receiving PORT. Among the 11 studies, only two were randomized controlled, with one of them reporting improved disease-free (P = 0.041) but not overall survival (P = 0.073), while the other finding no difference in survival. Furthermore, three more studies reported on DFS and/or locoregional recurrence of the disease. One of these studies reported a significantly improved DFS among patients receiving PORT (P = 0.003), while two of them reported a reduced rate of locoregional recurrence in this group (P = 0.032-0.009). Many studies report a positive effect of PORT when combined in parallel or sequentially with adjuvant chemotherapy in terms of long-term, disease free survival or locoregional control of the disease in patients who have undergone surgical resection of NSCLC and are found to harbour N2 disease. However, these reports are counterbalanced by an almost equal number of studies which show no difference between PORT and no PORT. Only one study reported significantly increased radiation related adverse effects in patients undergoing chemotherapy and PORT.
