Abstract
Background The role of postoperative radiotherapy (PORT) for patients with completely resected stage N2 non-small-cell lung cancer (NSCLC) has been controversial. This study aimed to investigate the efficacy of PORT and prognosis in these patients. Objectives An updated meta-analysis was conducted in this study to investigate the efficacy of PORT and prognosis in patients with completely resected and pathologically confirmed stage N2 NSCLC. Design This study is a systematic review and meta-analysis. Data source and methods Databases were searched up to 2 March 2022. All trials on patients with completely resected and pathologically confirmed stage N2 NSCLC undergoing PORT were screened, and data indicators in the PORT and non-PORT groups were extracted, respectively. The effect of PORT on overall survival (OS), disease-free survival (DFS), local recurrence-free survival (LRFS), and distant metastasis-free survival (DMFS) was estimated. Subgroup and sensitivity analyses were performed. Results In all, 20 studies involving 6340 patients were finally included. The PORT significantly increased OS [hazard ratio (HR) = 0.77, 95% CI: 0.71-0.84, p < 0.001), LRFS (HR = 0.63, 95% CI: 0.52-0.76, p < 0.001), and DFS (HR = 0.72, 95% CI: 0.63-0.82, p < 0.001) while it showed no significant difference in improving DMFS (HR = 0.86, 95% CI: 0.71-1.05, p = 0.14). Conclusion Our results suggest that in the postoperative treatment of patients with completely resected and pathologically confirmed stage N2 NSCLC, the addition of PORT provides better local recurrence control and survival benefit, but no benefit for distant metastases. The PORT may be incorporated into the postoperative treatment options for some patients with high-risk factors. However, it needs to be validated by more prospective studies in the future.

Abstract
The controversy over the efficacy of postoperative radiotherapy (PORT) has existed for a long time. The present study reassessed the overall survival (OS) and disease-free survival (DFS) data to investigate whether PORT can improve survival in resectable non-small cell lung cancer (NSCLC) patients. The following databases were used to perform literature search: PubMed, Web of Science, China National Knowledge Infrastructure (CNKI), and Embase (from January 1, 1986 to July 5, 2021). The results of overall survival (OS) and disease-free survival (DFS) were calculated as hazard ratio (HR). Confidence intervals are chosen with 95% confidence intervals. A total of 12 RCTs and 19 retrospective cohort studies were found to meet the inclusion criteria. A significant DFS improvement was detected in the PORT group (4111 patients from 15 studies), although statistical difference was not detected for OS between the non-PORT and PORT groups (31 studies, 49,342 total patients). PORT prolonged OS in patients undergoing PORT plus postoperative chemotherapy (POCT) and in pN2 patients. Patients with a median radiation dose of 50.4 Gy and a median radiation dose of 54 Gy had a better OS after PORT. However, if the total radiotherapy dose went up to 60 Gy, PORT increased the risk of death in NSCLC patients. Significant difference in OS was not found in the results of studies with regard to treatment methods, pathologic stages, study type, radiation beam quality, and radiation dose. Patients undergoing postoperative chemoradiotherapy and pN2 patients can benefit from PORT. Patients exposed to median radiation doses of 50.4 and 54 Gy demonstrated relatively good efficacy. For patients with non-small-cell lung cancer, PORT has not been proven to extend OS, but its effect on DFS remains strong.

Abstract
OBJECTIVE To summarize the principal studies investigating the role of postoperative radiation therapy (PORT) for non-small cell lung cancer (NSCLC) and to discuss the recent major breakthroughs deriving from the Lung ART trial, in order to provide a real-world scenario of the management of resected NSCLC patients. BACKGROUND Surgery followed by platinum-based chemotherapy remains the mainstay of adjuvant treatments for completely resected stage II and IIIA NSCLC. Less consistent is the employment of PORT, as no significant benefit was clearly identified from the previous published meta-analysis. Furthermore, the recent results of Lung ART trial questioned for the first time the efficacy of PORT for pathological N2 (pN2) NSCLC patients. Hence, the need to define if PORT still has a role for resected NSCLC and which subgroup of patients could benefit most from this treatment. METHODS A literature search of PubMed was performed to identify publications, including prospective and retrospective clinical studies, meta-analysis and systematic review of PORT for NSCLC. No limit concerning years of publication or publication status were applied. Only papers using the English language were selected. The ESMO 2020 and ESMO 2021 online resources were used to analyze the Lung ART trial results. The authors provide a narrative summary of the findings and implications of these studies and how they improve the clinical practice. CONCLUSIONS PORT was considered the standard of care for patients with completely resected pN2 NSCLC based on the results of an old meta-analysis that did not demonstrate a detrimental effect. The more recent randomized phase III Lung ART trial concluded that PORT could not anymore be recommended for pN2 NSCLC as a significant benefit in terms of 3 years disease-free survival (DFS) was not reached and an increased rate of radiotherapy related toxicity was observed. Retrospective studies suggest a possible role of PORT for incompletely resected NSCLC patients and those with an extranodal extension (ENE), but this issue needs to be reinforced from randomized prospective trials. The extensive publication of Lung ART trial is largely awaited to define if there is a role of PORT for resected NSCLC patients.

Postoperative Radiotherapy for Patients With Resectable Stage III-N2 Non-Small Cell Lung Cancer: A Systematic Review and Meta-Analysis. Front Oncol 2021; 11:680615.

Abstract
Purpose For resectable cases of stage III-N2 non-small cell lung cancer (NSCLC), the best treatment after surgery is still uncertain. The effect of postoperative radiotherapy (PORT) is controversial. Thus, we performed this updated meta-analysis to reassess the data of PORT in stage III-N2 NSCLC patients, to figure out whether these patients can benefit from PORT. Methods We conducted searches of the published literature in EMBASE, PubMed, and the Cochrane Library for relevant randomized control trials (RCTs) comparing PORT group with the non-PORT group in NSCLC patients at stage III-N2. These studies allowed the prior chemotherapy in the treatment. We extracted the data from these articles and used the hazard ratios (HRs) and their 95% confidence intervals (CIs) as summary statistics for estimating the effect of PORT on overall survival (OS), disease-free survival (DFS), local-regional recurrence-free survival (LRFS). Result The analyses of seven randomized controlled trials (1,318 participants) show no benefit of PORT on survival (HR, 0.87; 95% CI, 0.71 to 1.07; p = 0.18) but a significantly different effect of PORT on DFS (HR, 0.83; 95% CI, 0.71 to 0.97; p = 0.02) and LRFS (HR, 0.64; 95% CI, 0.50 to 0.81; p = 0.0003). There is not enough evidence of a difference in the effect on survival by the utility of chemotherapy along with PORT though subgroup analysis of no chemotherapy group, concurrent chemoradiotherapy and sequential chemoradiotherapy group. Even in trials with 3D-CRT radiation technique, the pooled analysis shows no benefit of PORT on survival in patients with stage III-N2 NSCLC (data is not shown). Conclusion Our findings illustrate that in the postoperative treatment for patients with stage III-N2 NSCLC, PORT contributes to a significantly increased DFS and LR and may not associate with an improved OS, indicating a cautious selection.

Abstract
BACKGROUND Adjuvant treatment for both small-cell and non-small-cell lung cancer is a controversial topic. There are no published results from prospective studies that either confirm or reject the benefit of adjuvant radiotherapy, although the presentation of recent studies at a number of conferences questions whether there should be a change in the paradigm of adjuvant RT for lung cancer. AIM The main goal of this study is to review the most relevant publications on the topic, updating the state of the matter regarding adjuvant radiotherapy following lung surgery, and analyzing the role of chemotherapy in the process. RELEVANCE FOR PATIENTS This review aims to assess the potential benefit of PORT in NSCLC and SCLC patients by looking at recent research. In doing so, it will be possible to determine which patients might benefit from it as adjuvant treatment after pulmonary resection.

Abstract
Locally advanced non-small cell lung cancer, especially mediastinal lymph node metastasis-positive stage IIIA-N2 cancer, is a heterogeneous disease state characterized by anatomically locally advanced disease with latent micrometastases. Thus, surgical resection or radiotherapy alone has historically failed to cure this disease. During the last three decades, persistent efforts have been made to develop a suitable treatment modality to overcome these problems using chemotherapy and/or radiotherapy with surgical resection. However, the role of surgical resection remains unclear, and the standard treatment for stage IIIA-N2 disease is concurrent chemoradiotherapy. In general, adjuvant chemotherapy is indicated for completely resected pathological stage IB disease or lymph node metastasis-positive pathological stage II or IIIA disease. Platinum-based doublet cytotoxic chemotherapy is currently the standard regimen. Additionally, post-operative radiotherapy might be indicated for post-operatively proven mediastinal lymph node metastasis; i.e. clinical N0-1 and pathological N2 disease. With the remarkable progression that has recently been made in the field of chemotherapy, such as advances in molecular targeting agents and immune checkpoint inhibitors, the basic policy of chemotherapy has been shifting to personalized treatment based on the individual patient's oncogene driver mutation status, immune status and other parameters. The same trend is being seen in the treatment of stage IIIA-N2 disease. We should consider the past and upcoming results of several clinical trials to optimize the coming era of personalized treatment.

Abstract
Background The patterns of local failure in stage pN2 nonsmall-cell lung cancer (NSCLC) patients undergoing radical resection and adjuvant chemotherapy are controversial. Methods The sites of local failure were compared in subgroups of patients with relevant clinicopathologic features (e.g., location and size of primary lesions). Results Totally 75 patients with local failure after radical resection and adjuvant chemotherapy for pN2 NSCLC were included in the analysis. Thirty-seven (49.3%) patients had distant metastasis. The median duration from surgical resection to local failure was 11 months (range: 3-45 months). Sites with ≥10% failure rate in all subgroups based on the location of the primary lesions included 4R, 7, the ipsilateral hilum, and the stump. Additional sites with ≥10% failure rate included 2R, 2L, 4L, and 5 for lesions in the left upper lobe; 4L and 5 for lesions in the left lower lobe; and 2R and 3P for lesions in the right upper-middle lobe. Squamous cell carcinoma affected the stump failure rate compared to adenocarcinoma (56.3% vs. 18.0%, P = 0.003). Tumor diameter ≥5 cm affected the stump failure rate compared to tumor diameter < 5 cm (44.0% vs. 18.0%, P = 0.016). Skip N2 metastasis affected the ipsilateral hilum failure rate compared to nonskip N2 metastasis (7.5% vs. 31.4%, P = 0.008). Conclusions For pN2 NSCLC patients undergoing radical resection and adjuvant chemotherapy, different lung lobes had different high-risk failure sites. Left lung cancer is prone to bilateral mediastinal lymph nodes recurrence, while right lung cancer mainly recurs with ipsilateral mediastinal lymph nodes. Moreover, the local failure patterns are influenced by pathological type, tumor size, and skip N2 metastasis.

Abstract
Background This study aimed to evaluate the long-term survival outcomes of patients undergoing neoadjuvant chemoradiotherapy or adjuvant chemoradiotherapy for T1-4N0-1M0 disease. Methods Patients with pT1-4N0-1M0 between 2010 and 2015 who received pre- or postoperative (R0 resection) chemoradiotherapy were identified. The exclusion criteria included N2 or M1 disease, immunotherapy, and targeted therapy. The staging was recalculated according to the new 8th edition TNM classification. Survival and predictors were assessed using Kaplan-Meier and multivariate Cox proportional-hazards model. Propensity-score matching with a ratio of 2:1 was performed to reduce bias in various clinicopathological factors. Results Of the 1,769 patients who met the inclusion criteria, 407 and 814 were included in the neoadjuvant and adjuvant chemoradiotherapy group, respectively, after propensity-score matching. The 5-year overall survival (OS) and cancer-specific survival (CSS) were 38.1% and 40.0% for neoadjuvant chemoradiotherapy and 26.3% and 26.5% for adjuvant chemoradiotherapy, respectively [P<0.0001, hazard ratio (HR): 0.7418, 95% confidence interval (CI): 0.6434-0.8553; P<0.0001, HR: 0.7444, 95% CI: 0.6454-0.8587)]. When stratified by stage, stage IIA (P=0.4166, HR: 0.8575, 95% CI: 0.5917-1.243) and IIIA (P=0.0740, HR: 0.7687, 95% CI: 0.5748-1.028) did not show improved 5-year OS in patients receiving neoadjuvant chemoradiotherapy. When stratified by age, similar trends were observed for patients aged more than 75 years. The multivariable analysis showed a significant association of neoadjuvant chemoradiotherapy with better survival. Conclusions Neoadjuvant chemoradiotherapy might improve the long-term survival of patients with stage I-IIIA non-small cell lung cancer (NSCLC). For patients aged more than 75 years, neoadjuvant chemoradiotherapy was not associated with an improvement in survival.

Abstract
Objectives: The role of postoperative radiotherapy (PORT) in the treatment of patients with completely resected non-small cell lung cancer (NSCLC) is not clear. Few study explored the trends of the PORT use. In this study, we examine the status of PORT use of completely resected NSCLC in mainland China. Methods: From 2005 to 2014, patients with primary lung cancer from eight hospitals across seven geographic regions of mainland China were selected. Then patients with staged I–IIIA NSCLC receiving radical surgery were enrolled in this study. The chi-square test was used to compare differences in the use of PORT among the groups of different age, regions and stages. The Cochran-Armitage trend test was used to identify the trend in the PORT use from 2005 to 2014. Results: Totally, 2,253 out of 7,184 patients were with staged I–IIIA NSCLC receiving completely resection. Only 122 patients (5.42%) received PORT. During this decade, the use of PORT declined significantly (p = 0.0002). In high socio-economic areas, the percentage of PORT use was 7.43%, which was significantly higher than 1.34% in the low socio-economic areas (p < 0.0001). Age was also associated with PORT use (p = 0.0747). For N0-1 and N2 NSCLC, the proportions of PORT use were 4.01 and 10.22%, respectively (p < 0.0001). And in N0-1 or N2 NSCLC, the proportions both decreased significantly during this decade (p = 0.009 and 0.026, respectively). For stage I, IIA, IIB and IIIA, the proportions who received PORT were 2.59, 4.65, 5.49, and 10.29%, respectively (p < 0.0001). Modern radiation techniques were widely used, but the volumes and doses varied widely. The proportions of using IMRT and EPID/IGRT increased after 2012. Conclusions: In China, the use of PORT was less than developed countries and had a declined trend. The use of PORT was related to disease stages, patients' age and geographic location. Both in N0-1 and N2 diseases, the use of PORT declined. Proper education of radiation doctors was urgently needed.

Long-term effects of neoadjuvant radiotherapy, adjuvant radiotherapy, and chemotherapy-only on survival of locally advanced non-small cell lung Cancer undergoing surgery: a propensity-matched analysis. BMC Cancer 2018; 18:1067. [PMID: 30400782 PMCID: PMC6219254 DOI: 10.1186/s12885-018-4900-x] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2018] [Accepted: 10/03/2018] [Indexed: 02/07/2023] Open
Abstract
Background The optimal timing of radiotherapy (RT) with respect to surgery remains controversial for locally advanced non-small cell lung cancer (LA NSCLC) undergoing surgery and the long-term effect of neoadjuvant RT, adjuvant RT, and chemotherapy-only on survival is unknown. Methods A retrospective study with Greedy 5 → 1 Digit propensity score matching technique was performed for locally advanced NSCLC patients identified from the Surveillance, Epidemiology, and End Results (SEER) database during 2004 to 2012. Kaplan-Meier and the log-rank test were conducted to compare NSCLC-specific survival. Cox proportional hazards multivariable regression was performed to assess the impact of different treatment regimens on cancer-specific mortality after adjustment for demographic factors, histology type, tumor grade, tumor size, nodal stage, and extent of resection. Results One thousand, two hundred and seventy-eight locally advanced NSCLC patients undergoing surgery were identified after propensity matching. Cox regression analyses showed the risk of cancer-specific mortality is not significantly different among neoadjuvant RT, adjuvant RT, and chemotherapy-only. Subgroup analyses showed that for patients with T1/2 & N2/3, the surgery plus chemotherapy-only group showed markedly higher mortality risk (HR = 1.42, 95%CI:1.10–1.83) than the neoadjuvant RT group. Other risk factors include older age, higher tumor grade, larger tumor size, and greater lymph node involvement. Conclusions The findings of this study suggest that the benefit of additional neoadjuvant or adjuvant RT to chemotherapy may be linked to a proper selection of LA NSCLC patients who undergo surgery. The timing of radiotherapy should be decided on the premise of fully considering patients’ condition and the quality of life after treatment.

Multimodality Therapy for N2 Non-Small Cell Lung Cancer: An Evolving Paradigm. Ann Thorac Surg 2018; 107:277-284. [PMID: 30227129 DOI: 10.1016/j.athoracsur.2018.07.033] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/20/2018] [Revised: 06/09/2018] [Accepted: 07/09/2018] [Indexed: 12/25/2022]
Abstract
BACKGROUND Induction chemoradiation for resectable N2 non-small cell lung cancer (NSCLC) is used with the intent to optimize locoregional control, whereas induction chemotherapy given in systemic doses is meant to optimally target potential distant disease. However, the optimal preoperative treatment regimen is still unknown and practice patterns continue to vary widely. We compared multiinstitutional oncologic outcomes for N2 NSCLC from 4 experienced lung cancer treatment centers. METHODS This collaborative retrospective study unites 4 major thoracic oncology centers. Patients with N2 NSCLC undergoing surgical resection after induction chemotherapy (CxT) or concurrent chemoradiation (CxRT) were included. Primary outcomes were overall and disease-free survival (OS and DFS). RESULTS 822 patients were identified (CxT = 662 and CxRT = 160). There were no differences in 5-year OS (CxT 39.9% versus CxRT 42.9%, p = 0.250) nor in DFS (CxT 28.7% versus 29.8%, p = 0.207). Recurrence rates (CxT 46.8% versus CxRT 51.6%, p = 0.282) and recurrence patterns were not significantly different (Local: CxT 9.8% versus CxRT 9.7%; and Distant: CxT 30.4% versus CxRT 33.1%, p = 0.764). There was no difference in perioperative mortality. In the analyses of patients who underwent pretreatment invasive mediastinal staging (n = 555), there were still no significant differences in OS (p = 0.341) and DFS (p = 0.455) between the 2 treatment strategies. CONCLUSIONS Both treatment strategies produce equivalent and better than expected outcomes compared with historical controls for N2 NSCLC, with no differences in recurrence patterns. How these conventional therapeutic strategies will compare with those involving immunotherapy combined with surgical locoregional disease control for N2 disease remains to be determined.

Abstract
BACKGROUND The management of N2 non-small cell lung cancer (NSCLC) found at operation is controversial. Current guidelines recommend adjuvant chemotherapy or adjuvant chemoradiotherapy. We evaluated whether adjuvant chemoradiotherapy was associated with improved survival compared with adjuvant chemotherapy in patients with N2 NSCLC after complete resection. METHODS We queried the National Cancer Database for all patients with clinical N0, pathologic N2 NSCLC who did not receive preoperative therapy and underwent complete (R0) surgical resection, followed by adjuvant chemotherapy or chemoradiotherapy. We performed propensity matching to create a well-balanced cohort of patients with respect to age, sex, race, comorbidities, treating facility, tumor size, year of diagnosis, and number of positive nodes. Survival was examined using the Kaplan-Meier method with log-rank analysis. RESULTS We identified 2,031 eligible patients; 1,149 (56.6%) received adjuvant chemotherapy and 882 (43.4%) received chemoradiotherapy. Patients in the unmatched cohort who received chemoradiotherapy tended to be younger (64.2 vs 65.4 years) and to have a comorbidity score of 0 (57.5% vs 52.1%). Median survival was similar (3.9 years with chemoradiotherapy vs 3.8 years with adjuvant chemotherapy, p = 0.518). We then identified 848 well-matched pairs and again did not detect differences in median survival (3.9 years with chemoradiotherapy vs 3.8 years with adjuvant chemotherapy, p = 0.705). CONCLUSIONS In a large database study, the addition of radiotherapy to adjuvant chemotherapy after resection of N2 NSCLC was not associated with improved survival. Until more definitive data are available, consideration should be given to treating patients with N2 disease detected at resection with adjuvant chemotherapy only.

Abstract
BACKGROUND A previous meta-analysis (MA) found postoperative radiotherapy (PORT) in lung cancer patients to be detrimental in N0/N1 patients and equivocal in the N2 setting. We hypothesized that treatment plans generated using MA protocols had worse dosimetric outcomes compared to modern plans. PATIENTS AND METHODS We retrieved plans for 13 patients who received PORT with modern planning. A plan was recreated for each patient using the 8 protocols included in MA. Dosimetric values were then compared between the modern and simulated MA plans. RESULTS A total of 104 MA plans were generated. Median prescribed dose was 50.4 (range, 50-60) Gy in the modern plans and 53.2 (30-60) Gy in the MA protocols. Median planning volume coverage was 96% (93%-100%) in the modern plans, versus 58% (0%-100%) in the MA plans (P < .001). Internal target volume coverage was 100% (99%-100%) versus 65% (0%-100%), respectively (P < .001). Organs at risk received the following doses: spinal cord maximum dose, 36.8 (4.6-50.4) Gy versus 46.8 (2.9-74.0) Gy (P < .001); esophageal mean dose, 22.9 (5.5-35) Gy versus 30.5 (11.1-52.5) Gy (P = .003); heart V30 (percentage of volume of an organ receiving at least a dose of 30 Gy), 16% (0%-45%) versus 35% (0%-79%) (P = .047); mean lung dose, 12.4 (3.4-24.3) Gy versus 14.8 (4.1-27.4) Gy (P = .008); and lung V20, 18% (4%-34%) versus 25% (8%-67%) (P = .023). CONCLUSION We quantitatively confirm the inferiority of the techniques used in the PORT MA. Our analysis showed a lower therapeutic ratio in the MA plans, which may explain the poor outcomes in the MA. The findings of the MA are not relevant in the era of modern treatment planning.

Abstract
Background To investigate the effects of postoperative radiotherapy (PORT) on the survival of patients with resected stage IIIA-N2 non-small cell lung cancer (NSCLC). Methods A total of 3,334 patients with resected stage IIIA-N2 NSCLC in 2004 to 2013 were identified in the Surveillance, Epidemiology, and End Results database and stratified according to use of PORT. Propensity score-matching (PSM) methods were used to balance the baseline characteristics of patients who did (n = 744) or did not (n = 744) undergo PORT. Overall survival (OS) and lung cancer-specific survival (LCSS) were compared between these two patient groups. Results After PSM, PORT increased OS (hazard ratio, 0.793; p = 0.001) and LCSS (hazard ratio, 0.837; p = 0.022) compared with no PORT. The OS benefit for PORT was mainly seen in patients aged <60 years (5-year OS, 35.4% versus 28.9% for PORT versus no PORT, respectively; p = 0.026) and in those who underwent lobectomy (5-year OS, 43.5% versus 34.5% for PORT versus no PORT, respectively; p = 0.001). The LCSS benefit for PORT was significant in patients undergoing lobectomy (5-year LCSS, 48.3% versus 42.3% for PORT versus no PORT, respectively; p = 0.036). Conclusions The survival benefits of PORT were primarily observed in patients with resected stage IIIA-N2 NSCLC who were <60 years of age or had undergone lobectomy.

Abstract
AbstractAimTo perform a retrospective analysis of survival, local–regional control and the effect of prognostic factors in 61 non-small cell lung cancer patients who were treated with postoperative radiotherapy (PORT) by a linear accelerator (LINAC).Material and methodsA total of 50–66 Gy PORT with a fractional dose of 1·8–2 Gy was administered to 24 patients (24·5%) for surgical margin positivity, 33 patients (54%) for mediastinal lymph node involvement and 13 patients (21·5%) for both mediastinal lymph node involvement and positive surgical margins.ResultsMedian follow-up was 17 months, and the median survival and median distant metastasis-free survival were 25 and 19 months, respectively. Local-regional progression was observed in 10 patients (16·4%). Treatment modality (2D/3D) (p=0·021), tumour size >4 cm (p=0·004), surgical margin positivity (p=0·001), and left lung localisation of the tumour (p≤0·05) were the prognostic factors in terms of survival.ConclusionsA survey of the literature shows that, without PORT, local recurrence or progression rates increase while overall survival rates decrease. In this study, only patients with PORT are studied and the results show that the local progression and overall survival rates are comparable with literature of LINAC-based PORT. In the case of overall survival, 3D treatment shows better results than 2D treatment modality.

Abstract
Purpose
The optimal adjuvant therapy modality for treating pN2 non-small cell lung cancer patients has not yet been established. In this study, the authors investigated clinical outcomes following three different adjuvant therapy modalities.
Materials and Methods
From January 2006 to December 2012, 240 patients with cN0/1 disease were found to have pN2 disease following curative resection and received one of three adjuvant therapy modalities:thoracic radiation therapy (TRT) and concurrent chemotherapy (CTx) (CCRT) (group I), CCRT plus consolidation CTx (group II), and CTx alone (group III). TRT was delivered to 155 patients (groups I/II), and full dose CTx was delivered to 172 patients either as a consolidative or a sole modality (group II/III).
Results
During 30 months of median follow-up, 44 patients died and 141 developed recurrence. The 5-year overall survival (OS), locoregional control (LRC), distant metastasis-free survival (DMFS), and disease-free survival (DFS) rates of all patients were 76.2%, 80.7%, 36.4%, and 29.6%, respectively. There was no difference in OS among groups. TRT (groups I/II) significantly improved LRC, full dose CTx (groups II/III) did DMFS, and CCRT plus consolidation CTx (group II) did DFS, respectively. Conclusion
The current study could support that TRT could improve LRC and full dose CTx could improve DMFS and that CCRT plus consolidation CTx could improve DFS.

Abstract
BACKGROUND The role of postoperative radiotherapy (PORT) in the treatment of patients with completely resected non-small cell lung cancer (NSCLC) was not clear. A systematic review and individual participant data meta-analysis was undertaken to evaluate available evidence from randomised controlled trials (RCTs). These results were first published in Lung Cancer in 2013. OBJECTIVES To evaluate the effects of PORT on survival and recurrence in patients with completely resected NSCLC. To investigate whether predefined patient subgroups benefit more or less from PORT. SEARCH METHODS We supplemented MEDLINE and CANCERLIT searches (1965 to 8 July 2016) with information from trial registers, handsearching of relevant meeting proceedings and discussion with trialists and organisations. SELECTION CRITERIA We included trials of surgery versus surgery plus radiotherapy, provided they randomised participants with NSCLC using a method that precluded prior knowledge of treatment assignment. DATA COLLECTION AND ANALYSIS We carried out a quantitative meta-analysis using updated information from individual participants from all randomised trials. We sought data on all participants from those responsible for the trial. We obtained updated individual participant data (IPD) on survival and date of last follow-up, as well as details on treatment allocation, date of randomisation, age, sex, histological cell type, stage, nodal status and performance status. To avoid potential bias, we requested information on all randomised participants, including those excluded from investigators' original analyses. We conducted all analyses on intention-to-treat on the endpoint of survival. MAIN RESULTS We identified 14 trials evaluating surgery versus surgery plus radiotherapy. Individual participant data were available for 11 of these trials, and our analyses are based on 2343 participants (1511 deaths). Results show a significant adverse effect of PORT on survival, with a hazard ratio of 1.18, or an 18% relative increase in risk of death. This is equivalent to an absolute detriment of 5% at two years (95% confidence interval (CI) 2% to 9%), reducing overall survival from 58% to 53%. Subgroup analyses showed no differences in effects of PORT by any participant subgroup covariate.We did not undertake analysis of the effects of PORT on quality of life and adverse events. Investigators did not routinely collect quality of life information during these trials, and it was unlikely that any benefit of PORT would offset the observed survival disadvantage. We considered risk of bias in the included trials to be low. AUTHORS' CONCLUSIONS Results from 11 trials and 2343 participants show that PORT is detrimental to those with completely resected non-small cell lung cancer and should not be used in the routine treatment of such patients. Results of ongoing RCTs will clarify the effects of modern radiotherapy in patients with N2 tumours.

Abstract
Objective The use of postoperative radiotherapy (PORT) remains controversial for Stage IIIA-N2 non-small-cell lung cancer (NSCLC) patients, a possible reason is that IIIA-pN2 NSCLC diseases are a heterogeneous group with different clinicopathologic features. The aim of this research was to prove whether the mediastinal lymph nodes’ (LNs) skipping status could indicate the necessity of the PORT for the pN2 NSCLC patients. Methods The skip metastasis was defined as pN0N2 (no N1 LN involved), and nonskip metastasis was pN1N2 (one or more N1 LNs involved). Patients were divided into two groups: LNs nonskip and LNs skip, and postoperative chemoradiotherapy (POCRT) and postoperative chemotherapy. Then, the LN nonskip and LN skip groups were further divided into subgroups: POCRT and point of care testing (POCT) for subgroup analysis. Results There were 220 cases included in the analysis, and 43 of them received PORT. On univariate analysis, the median 3-year progression-free survival (PFS) was, respectively, 16 months (27.7%) for the LN skip group and 11 months (15.3%) for the LN nonskip group (P=0.001). The median 3-year overall survival (OS) was, respectively, 35 months (47.0%) for the LN skip group and 27 months (38.7%) for the LN nonskip group (P=0.025). The median 3-year local recurrence-free survival (LRFS) was, respectively, 25 months (41.0%) for the LN skip group and19 months (29.9%) for the LN nonskip group (P=0.014). The median 3-year distant metastasis-free survival (DMFS) was, respectively, 22 months (32.5%) for the LN skip group and 15 months (20.4%) for the LN nonskip group (P=0.013). The median 3-year PFS was, respectively, 17 months (25.6%) for the POCRT group and 12 months (18.6%) for the POCT group (P=0.037). Although the POCRT group showed better OS, LRFS, and DMFS than the POCT group, the results showed no statistical significance. In subgroup analysis, there was no statistical significance in the Kaplan–Meier analysis between subgroups, but it showed that POCRT resulted in better PFS, OS, and DMFS in both LN skip and LN nonskip subgroups; this advantage was more obvious in the LN skip subgroup. Conclusion The LN skip status is closely related to the survival of the IIIA-N2 NSCLC disease, and the LN skip patients may get more benefit in PFS and LRFS than the LN nonskip patients from PORT.

Abstract
PURPOSE To provide guidance to physicians and patients with regard to the use of adjuvant external beam radiation therapy (RT) in locally advanced non-small cell lung cancer (LA NSCLC) based on available medical evidence complemented by consensus-based expert opinion. METHODS AND MATERIALS A panel authorized by the American Society for Radiation Oncology (ASTRO) Board of Directors and Guidelines Subcommittee conducted 2 systematic reviews on the following topics: (1) indications for postoperative adjuvant RT and (2) indications for preoperative neoadjuvant RT. Practice guideline recommendations were approved using an a priori-defined consensus-building methodology supported by ASTRO and approved tools for the grading of evidence quality and the strength of guideline recommendations. RESULTS For patients who have undergone surgical resection, high-level evidence suggests that use of postoperative RT does not influence survival, but optimizes local control for patients with N2 involvement, and its use in the setting of positive margins or gross primary/nodal residual disease is recommended. No high-level evidence exists for the routine use of preoperative induction chemoradiation therapy; however, modern surgical series and a post-hoc Intergroup 0139 clinical trial analysis suggest that a survival benefit may exist if patients are properly selected and surgical techniques/postoperative care is optimized. CONCLUSIONS A consensus and evidence-based clinical practice guideline for the adjuvant radiotherapeutic management of LA NSCLC has been created addressing 2 important questions.

Abstract
The rate of local failure of stage IIIA-N2 non-small cell lung cancer is 20 to 40%, even if they are managed with surgery and adjuvant chemotherapy. Postoperative radiotherapy improves local control, but its benefit on global survival remains to be demonstrated. Considered for many years as an adjuvant treatment option for pN2 cancers, it continues nevertheless to be deemed too toxic. What is the current status of postoperative radiotherapy? The Lung Adjuvant Radiotherapy Trial (Lung ART) phase III trial should give us a definitive, objective response on global survival, but inclusion of patients is difficult. The results are consequently delayed. The aim of this review is to show all the results about efficacy and tolerance of postoperative radiotherapy and to define the target volume and dose to prescribe.

Abstract
Locally advanced non-small cell lung cancer (NSCLC) is a diversified illness in which postoperative radiation therapy (PORT) for complete resection with positive hiliar (pN1) and/or mediastinal (pN2) lymph nodes is controversial. Although several studies have shown that PORT has beneficial effects, randomized trials are needed to demonstrate its impact on overall survival. In this review, the Spanish Radiation Oncology Group for Lung Cancer describes the most relevant literature on PORT in NSCLC patients stage pN1-2. In addition, we have outlined the current recommendations of different national and international clinical guidelines and have also specified practical issues regarding treatment volume definition, doses and fractionation.

Abstract
Most long-term survivors of non-small-cell lung cancer (NSCLC) are patients who have had a completely resected tumour. However, this is only achievable in about 30% of the patients. Even in this highly selected group of patients, there is still a high risk of both local and distant failure. Adjuvant treatments such as chemotherapy (CT) and radiotherapy (RT) have therefore been evaluated in order to improve their outcome. In patients with stage II and III, administration of adjuvant platinum-based chemotherapy is now considered the standard of care, based on level 1 evidence. The role of postoperative radiation therapy (PORT) remains controversial. In the PORT meta-analysis published in 1998, the conclusions were that if PORT was detrimental to patients with stage I and II completely resected NSCLC, the role of PORT in the treatment of tumours with N2 involvement was unclear and further research was warranted. Thus at present, after complete resection, adjuvant radiotherapy should not be administered in patients with early lung cancer. Recent retrospective and non-randomised studies, as well as subgroup analyses of recent randomised trials evaluating adjuvant chemotherapy, provide evidence of the possible benefit of PORT in patients with mediastinal nodal involvement. The role of PORT needs to be evaluated also for patients with proven N2 disease who undergo neoadjuvant chemotherapy followed by surgery. The risk of local recurrence for N2 patients varies between 20% and 60%. Based on currently available data, PORT should be discussed for fit patients with completely resected NSCLC with N2 nodal involvement, preferably after completion of adjuvant chemotherapy or after surgery if patients have had preoperative chemotherapy. There is a need for new randomised evidence to reassess PORT using modern three-dimensional conformal radiation technique, with attention to normal organ sparing, particularly lung and heart, to reduce the possible over-added toxicity. Quality assurance of radiotherapy as well as quality of surgery – and most particularly nodal exploration modality – should both be monitored. A new large multi-institutional randomised trial Lung ART evaluating PORT in this patient population is needed and is now under way.

Abstract
In completely resected non-small-cell lung cancer (NSCLC) patients with pathologically involved mediastinal lymph nodes (N2), administration of adjuvant platinum-based chemotherapy is now considered the standard of care, based on level 1 evidence. The role of post-operative radiotherapy (PORT) in this group of patients remains controversial. In the PORT meta-analysis published in 1998, the conclusions were that if adjuvant radiotherapy was detrimental to patients with early-stage completely resected NSCLC, the role of PORT in the treatment of tumours with N2 involvement was unclear and further research was warranted. Recent retrospective and non-randomized studies as well as subgroup analyses of recent randomized trials evaluating adjuvant chemotherapy, provide evidence of the possible benefit of PORT in patients with mediastinal nodal involvement. The question of PORT indication is also valid for those patients with proven N2 disease who undergo neo-adjuvant chemotherapy followed by surgery. The risk of local recurrence for N2 patients varies between 20% and 60%. Based on currently available data, PORT should be discussed for fit patients with completely resected NSCLC with N2 nodal involvement, within a multidisciplinary setting, preferably after completion of adjuvant chemotherapy or after surgery if patients have had neo-adjuvant chemotherapy. There is need for new randomized evidence to reassess PORT using modern three-dimensional conformal radiation technique, with attention to normal organ sparing, particularly lung and heart, to reduce the possible additional toxicity. Randomized evidence is needed. A new large international multi-institutional randomized trial Lung ART evaluating PORT in this patient population is now underway, as well as a Chinese study comparing postoperative sequential chemotherapy followed by radiotherapy versus adjuvant chemotherapy alone.

Abstract
PURPOSE This study was conducted to observe the outcomes of postoperative radiotherapy (PORT) with or without concurrent chemotherapy in resected non-small cell lung cancer (NSCLC) in single institution. MATERIALS AND METHODS From 2002 to 2013, 78 patients diagnosed with NSCLC after curative resection were treated with radiotherapy alone (RT, n = 48) or concurrent chemoradiation (CCRT, n = 30). The indications of adjuvant radiation therapy were N2 node positive (n = 31), close or involved resection margin (n = 28), or gross residual disease due to incomplete resection (n = 19). The median radiation dose was 57.6 Gy (range, 29.9 to 66 Gy). RESULTS Median survival time was 33.7 months (range, 4.4 to 140.3 months). The 5-year overall survival (OS) rate was 49.5% (RT 46% vs. CCRT 55.2%; p = 0.731). The 3-year disease-free survival rate was 45.5% (RT 39.4% vs. CCRT 55.3%; p = 0.130). The 3-year local control rate was 68.1% (RT 64.4% vs. CCRT 77.7%; p = 0.165). The 3-year DMFS rate was 56.1% (RT 52.6% vs. CCRT 61.7%; p = 0.314). In multivariate analysis, age ≥66 years and pathologic stage III were significant poor prognostic factors for OS. Treatment failure occurred in 40 patients. Four patients had radiologically confirmed grade 3 radiation pneumonitis. CONCLUSION In NSCLC, adjuvant RT or CCRT after curative surgery is a safe and feasible modality of treatment. OS gain was seen in patients less than 66 years. Postoperative CCRT showed a propensity of achieving better local control and improved disease-free survival compared to RT alone according to our data.

Abstract
Lung cancer is one of the most common human malignancies and remains the leading cause of cancer related deaths worldwide. Many recent technological advances led to improved diagnostics and staging of lung cancer. With development of new treatment options such as targeted therapies there might be improvement in progression free survival of patients with advanced stage non-small cell lung cancer (NSCLC). Improvement in overall survival is still reserved for selected patients and selected treatments. One of the mostly investigated therapeutic options is adjuvant treatment. There are many open issues in selection of patients and administration of appropriate adjuvant treatment.

Abstract
Lung cancer remains the leading cause of death in the USA and is the most common cancer both in incidence and in mortality globally (1.35 million deaths annually). Non-small-cell lung cancer accounts for >80% of all lung cancers [1] . About 35-45% of non-small-cell lung cancer patients present with locally advanced non-metastatic stage III disease. However, confirmed stage III disease represents a very heterogeneous group ranging from borderline surgical candidate with minimal mediastinal involvement to bulky mediastinal nodes or contralateral nodal involvement with significant controversy regarding optimal management in these various situations. This article specifically addresses the role of surgery, radiotherapy and chemotherapy in multimodal approach to treat stage III patients with N2/N3 involvement and controversies surrounding these recommendations.

Risk factors for locoregional recurrence in patients with resected N1 non-small cell lung cancer: a retrospective study to identify patterns of failure and implications for adjuvant radiotherapy. Radiat Oncol 2013; 8:286. [PMID: 24321392 PMCID: PMC3922909 DOI: 10.1186/1748-717x-8-286] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2013] [Accepted: 12/06/2013] [Indexed: 12/25/2022] Open
Abstract
Background Meta-analysis of randomized trials has shown that postoperative radiotherapy (PORT) had a detrimental effect on overall survival (OS) in patients with resected N1 non–small cell lung cancer (NSCLC). Conversely, the locoregional recurrence (LR) rate is reported to be high without adjuvant PORT in these patients. We have evaluated the pattern of failure, actuarial risk and risk factors for LR in order to identify the subset of N1 NSCLC patients with the highest risk of LR. These patients could potentially benefit from PORT. Methods We conducted a retrospective study on 199 patients with pathologically confirmed T1–3N1M0 NSCLC who underwent surgery. None of the patients had positive surgical margins or received preoperative therapy or PORT. The median follow-up was 53.8 months. Complete mediastinal lymph node (MLN) dissection and examination was defined as ≥3 dissected and examined MLN stations; incomplete MLN dissection or examination (IMD) was defined as <3 dissected or examined MLN stations. The primary end point of this study was freedom from LR (FFLR). Differences between patient groups were compared and risk factors for LR were identified by univariate and multivariate analyses. Results LR was identified in 41 (20.6%) patients, distant metastasis (DM) was identified in 79 (39.7%) patients and concurrent LR and DM was identified in 25 (12.6%) patients. The 3- and 5-year OS rates in patients with resected N1 NSCLC were 78.4% and 65.6%, respectively. The corresponding FFLR rates were 80.8% and 77.3%, respectively. Univariate analyses identified that nonsmokers, ≤23 dissected lymph nodes, visceral pleural invasion and lymph node ratio >10% were significantly associated with lower FFLR rates (P < 0.05). Multivariate analyses further confirmed positive lymph nodes at station 10 and IMD as risk factors for LR (P < 0.05). The 5-year LR rate was highest in patients with both these risk factors (48%). Conclusions The incidence of LR in patients with surgically resected T1–3N1M0 NSCLC is high. Patients with IMD and positive lymph nodes at station 10 have the highest risk of LR, and may therefore benefit from adjuvant PORT. Further investigations of PORT in this subset of patients are warranted.

Abstract
BACKGROUND We hypothesized that modern postoperative radiotherapy (PORT) could decrease local recurrence (LR) and improve overall survival (OS) in patients with stage IIIA-N2 non-small-cell lung cancer (NSCLC). METHODS To investigate the effect of modern PORT on LR and OS, we identified published phase III trials for PORT and stratified them according to use or non-use of linear accelerators. Non-individual patient data were used to model the potential benefit of modern PORT in stage IIIA-N2 NSCLC treated with induction chemotherapy and resection. RESULTS Of the PORT phase III studies, eleven trials (2387 patients) were included for OS analysis and eight (1677 patients) for LR. PORT decreased LR, whether given with cobalt, cobalt and linear accelerators, or with linear accelerators only. An increase in OS was only seen when PORT was given with linear accelerators, along with the most significant effect on LR (relative risk for LR and OS 0.31 (p=0.01) and 0.76 (p=0.02) for PORT vs. controls, respectively). Four trials (357 patients) were suitable to assess LR rates in stage III NSCLC treated with surgery, in most cases after induction chemotherapy. LR as first relapse was 30% (105/357) after 5 years. In the modeling part, PORT with linear accelerators was estimated to reduce LR rates to 10% as first relapse and to increase the absolute 5-year OS by 13%. CONCLUSIONS This modeling study generates the hypothesis that modern PORT may increase both LR and OS in stage IIIA-N2 NSCLC even in patients being treated with induction chemotherapy and surgery.

Abstract
Purpose Pathologic downstaging following chemotherapy for stage III-N2 NSCLC is a well-known positive prognostic indicator. However, the predictive factors for locoregional recurrence (LRR) in these patients are largely unknown. Methods Between 1998 and 2008, 153 patients with clinically or pathologically staged III-N2 NSCLC from two cancer centers in the United States were treated with induction chemotherapy and surgery. All had pathologic N0-1 disease, and none received postoperative radiotherapy. LRR were defined as recurrence at the surgical site, lymph nodes (levels 1–14 including supraclavicular), or both. Results Median follow-up was 39.3 months. Pretreatment N2 status was confirmed pathologically (18.2 %) or by PET/CT (81.8 %). Overall, the 5-year LRR rate was 30.8 % (n = 38), with LRR being the first site of failure in 51 % (22/+99877943). Five-year overall survival for patients with LRR compared with those without was 21 versus 60.1 % (p < 0.001). Using multivariate analysis, significant predictors for LRR were pN1 disease at time of surgery (p < 0.001, HR 3.43, 95 % CI 1.80–6.56) and a trend for squamous histology (p = 0.072, HR 1.93, 95 % CI 0.94–3.98). Five-year LRR rate for pN1 versus pN0 disease was 62 versus 20 %. Neither single versus multistation N2 disease (p = 0.291) nor initial staging technique (p = 0.306) were predictors for LRR. N1 status also was predictive for higher distant recurrence (p = 0.021, HR 1.91, 95 % CI 1.1–3.3) but only trended for poorer survival (p = 0.123, HR 1.48, 95 % CI 0.9–2.44). Conclusions LRR remains high in resected stage III-N2 NSCLC patients after induction chemotherapy and nodal downstaging, particularly in patients with persistent N1 disease.

Abstract
Among all nonmetastatic non-small-cell lung cancer (NSCLC) patients, the best survival rates are observed in patients who undergo surgery. Nevertheless, 5-year survival rates vary between 20% and 60% depending on the stage of the disease. Several combined modality treatments have been investigated to improve outcome in localized NSCLC. These include local treatment, systemic before local treatment, concomitant systemic and local treatments, and systemic after local treatment. Preoperative irradiation was shown to be of no benefit on local recurrence rates or overall survival. Even doses of radiation >/=40 grays (Gy) were associated with lower survival rates. Postoperative irradiation did not influence survival in stage III disease and seemed to be deleterious in stages I and II disease. Modern radiotherapy techniques might be of interest in this setting but have been insufficiently tested. The early phase III studies of preoperative chemotherapy versus primary surgery in stage III NSCLC showed a tremendous difference in favor of chemotherapy. A larger study did not confirm these results but suggested that preoperative chemotherapy might have a greater effect in stages I and II of the disease. In locally advanced disease, chemotherapy followed by radiotherapy was shown to increase survival when compared with radiotherapy alone. Studies comparing concurrent chemoradiation with radiotherapy only were in favor of the concomitant schedule, which improved local control. Promising results have been reported with chemoradiation followed by surgery in stage IIIa and even stage IIIb disease. Randomized studies of postoperative chemotherapy demonstrated a 5% improvement in 5-year survival over adjuvant-free treatment. Postoperative chemoradiation showed no advantage over postoperative radiotherapy. Several trials that are ongoing or whose accrual was recently completed should further define the role of perioperative chemotherapy in resectable NSCLC and of trimodality treatments in advanced disease. Targeted agents are being developed in the postoperative setting. New schedules of chemoradiation with higher therapeutic indexes are also being investigated in nonresectable stage III NSCLC.

The role of consolidation therapy for stage III non-small cell lung cancer with persistent N2 disease after induction chemotherapy. Ann Thorac Surg 2012; 94:914-20.

Abstract
BACKGROUND Persistent pathologic mediastinal nodal involvement after induction chemotherapy and surgical resection is a negative prognostic factor for stage III-N2 non-small cell lung cancer patients. This population has high rates of local-regional failure and distant failure, yet the effectiveness of additional therapies is not clear. We assessed the role of consolidative therapies (postoperative radiation therapy and chemotherapy) for such patients. METHODS In all, 179 patients with stage III-N2 non-small cell lung cancer at MD Anderson Cancer Center were treated with induction chemotherapy followed by surgery from 1998 through 2008; 61 patients in this cohort had persistent, pathologically confirmed, mediastinal nodal disease, and were treated with postoperative radiation therapy. Local-regional failure was defined as recurrence at the surgical site or lymph nodes (levels 1 to 14, including supraclavicular), or both. Overall survival was calculated using the Kaplan-Meier method, and survival outcomes were assessed by log rank tests. Univariate and multivariate Cox proportional hazards models were used to identify factors influencing local-regional failure, distant failure, and overall survival. RESULTS All patients received postoperative radiation therapy after surgery, but approximately 25% of the patients also received additional chemotherapy: 9 (15%) with concurrent chemotherapy, 4 (7%) received adjuvant sequential chemotherapy, and 2 (3%) received both. Multivariate analysis indicated that additional postoperative chemotherapy significantly reduced distant failure (hazard ratio 0.183, 95% confidence interval: 0.052 to 0.649, p=0.009) and improved overall survival (hazard ratio 0.233, 95% confidence interval: 0.089 to 0.612, p=0.003). However, additional postoperative chemotherapy had no affect on local-regional failure. CONCLUSIONS Aggressive consolidative therapies may improve outcomes for patients with persistent N2 disease after induction chemotherapy and surgery.

Abstract
BACKGROUND The potential role of postoperative radiation therapy (PORT) for patients who have completely resected, stage III nonsmall cell lung cancer (NSCLC) with N2 disease remains controversial. By using population-based data, the authors of this report compared the survival of a concurrent cohort of elderly patients who had N2 disease treated with and without PORT. METHODS By using the Surveillance, Epidemiology, and End Results (SEER) registry linked to Medicare records, 1307 patients were identified who had stage III NSCLC with N2 lymph node involvement diagnosed between 1992 and 2005. Propensity scoring methods and instrumental variable analysis were used to compare the survival of patients who did and did not receive PORT after controlling for selection bias. RESULTS Overall, 710 patients (54%) received PORT. Propensity score analysis indicated that PORT was not associated with improved survival in patients with N2 disease (hazard ratio [HR], 1.11; 95% confidence interval [CI], 0.97-1.27). Analyses that were limited to patients who did or did not receive chemotherapy, who received intermediate-complexity or high-complexity radiotherapy planning, or adjusted for time trends produced similar results. The instrumental variable estimator for the absolute improvement in 1-year and 3-year survival with PORT was -0.04 (95% CI, -0.15 to 0.08) and -0.08 (95% CI, -0.24 to 0.15), respectively. CONCLUSIONS The current data suggested that PORT is not associated with improved survival for elderly patients with N2 disease. These findings have important clinical implications, because SEER data indicate that a large percentage of elderly patients currently receive PORT despite the lack of definitive evidence about its effectiveness. The potential effectiveness of PORT should be evaluated further in randomized controlled trials.

Abstract
BACKGROUND For patients with resected pathological stage IIIA-N2 non-small cell lung cancer (NSCLC), the role of postoperative radiotherapy (PORT) is not well defined. In this single-institutional study, we re-evaluated the effect of PORT on overall survival (OS) as well as tumor control in this subgroup of patients. METHODS In 2003-2005, 221 consecutive patients with resected pathological stage IIIA-N2 NSCLC at our institution were retrospectively analyzed in an institutional review board-approved study. The effect of PORT on OS, cancer-specific survival (CSS), and disease-free survival (DFS) was evaluated using the Kaplan-Meier method and log-rank tests. The impact of PORT on locoregional control and distant metastasis was also analyzed. Results. Compared with the control, patients treated with PORT had a significantly longer OS time (χ2, 3.966; p = .046) and DFS interval (χ2, 6.891; p = .009), as well as a trend toward a longer CSS duration (χ2, 3.486; p = .062). Patients treated with PORT also had a significantly higher locoregional recurrence-free survival rate (χ2, 5.048; p = .025) as well as distant metastasis-free survival rate (χ2, 11.248; p = .001). Multivariate analyses showed that PORT was significantly associated with a longer OS duration (p = .000). CONCLUSIONS PORT can significantly improve the survival of patients with resected pathological stage IIIA-N2 NSCLC. A prospective randomized multicenter clinical trial is ongoing.

Abstract
In completely resected non-small cell lung cancer (NSCLC) patients with pathologically involved mediastinal lymph nodes (N2), administration of adjuvant platinum-based chemotherapy is now considered the standard of care, based on level 1 evidence. The role of postoperative radiation therapy (PORT) in this group of patients remains controversial. The PORT meta-analysis published in 1998 concluded that adjuvant radiotherapy was detrimental to patients with early-stage completely resected NSCLC, but that the role of PORT in the treatment of tumors with N2 involvement was unclear, and that further research was warranted. Recent retrospective and nonrandomized studies, as well as subgroup analyses of recent randomized trials evaluating adjuvant chemotherapy, provide evidence of the possible benefit of PORT in patients with mediastinal nodal involvement. The role of PORT is also a valid question in patients with proven N2 disease who have undergone only induction chemotherapy followed by surgery, because the local recurrence rate for such patients varies in the range of 20%-60%. Based on the currently available data, PORT should be discussed for fit patients with completely resected NSCLC with N2 nodal involvement, preferably after completion of adjuvant chemotherapy. There is a need for new randomized evidence to evaluate PORT using the modern three-dimensional conformal radiation technique, with attention paid to reducing the risk for, particularly, pulmonary and cardiac toxicity. A new large multi-institutional randomized trial evaluating PORT in this patient population is needed and now under way.

Abstract
BACKGROUND The objective of this study was to examine the effects of different definitions of local recurrence on the reported patterns of failure and associated risk factors in patients who undergo potentially curative resection for stage I nonsmall cell lung cancer (NSCLC). METHODS The study included 306 consecutive patients who were treated from 2000 to 2005 without radiotherapy. Local recurrence was defined either as 'radiation' (r-LR) (according to previously defined postoperative radiotherapy fields), including the bronchial stump, staple line, ipsilateral hilum, and ipsilateral mediastinum; or as 'comprehensive' (c-LR), including the same sites plus the ipsilateral lung and contralateral mediastinal and hilar lymph nodes. All recurrences that were not classified as "local" were considered to be distal. RESULTS The median follow-up was 33 months. The proportions of c-LR and r-LR at 2 years, 3 years, and 5 years were 14%, 21%, and 29%, respectively, and 7%, 12%, and 16%, respectively. Significant risk factors for c-LR on multivariate analysis were diabetes, lymphatic vascular invasion, and tumor size; and significant factors for r-LR were resection of less than a lobe and lymphatic vascular invasion. The proportions of distant (non-local) recurrence using these definitions at 2 years, 3 years, and 5 years were 10%, 12%, and 18%, respectively, and 14%, 19%, and 29%, respectively. Significant risk factors for distant failure were histology when using the c-LR definition and tumor size when using the r-LR definition. CONCLUSIONS Local recurrence increased nearly 2-fold when a broad definition was used instead of a narrow definition. The definition also affected which factors were associated significantly with both local and distant failure on multivariate analysis. Comparable definitions must be used when analyzing different series.
