Abstract
The advent of immune checkpoint inhibition has pushed the treatment paradigm for resectable non-small-cell lung cancer (NSCLC) toward neoadjuvant therapy. A growing number of promising trials have examined the utility of neoadjuvant immunotherapy, both alone and in combination with other modalities such as radiation therapy (RT) and chemotherapy. The phase II LCMC3 and NEOSTAR trials demonstrated a role for neoadjuvant immunotherapy in inducing meaningful pathologic responses, and another phase II trial established the feasibility of combining neoadjuvant durvalumab with RT. Significant interest in neoadjuvant chemoimmunotherapy resulted in the conduct of multiple successful phase II trials including the Columbia trial, NADIM, SAKK 16/14, and NADIM II. Across these trials, neoadjuvant chemoimmunotherapy led to high rates of pathologic response and improved surgical outcomes without compromising surgical timing or feasibility. CheckMate-816, which was a randomized phase III trial studying neoadjuvant nivolumab in addition to chemotherapy, definitively established a benefit for neoadjuvant chemoimmunotherapy compared to chemotherapy alone for resectable NSCLC. Despite the growing literature and success of these trials, several outstanding questions remain, including the relationship between pathologic response and patient survival, the role of biomarkers such as programmed death ligand 1 and circulating tumor DNA in determining patient selection and treatment course, and the utility of additional adjuvant therapies. Longer follow-up of CheckMate-816 and other ongoing phase III trials may help address these questions. Ultimately, the complexity of managing resectable NSCLC highlights the importance of a multidisciplinary approach to patient care.

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. [PMID: 34336667 PMCID: PMC8320322 DOI: 10.3389/fonc.2021.680615] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2021] [Accepted: 06/24/2021] [Indexed: 12/25/2022] Open
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.

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.

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.

Abstract
OBJECTIVE Elective nodal irradiation (ENI) of regional lymphatics has been a foundational paradigm for radiation oncologists in the treatment of nonsmall-cell lung cancer (NSCLC), but its utility has recently been called into question. This review summarizes the controversies surrounding ENI and reviews the therapeutic options available to treat regional lymphatics in NSCLC. METHODS Local failure after conventional radiotherapy (RT) occurs in 40% to 80% of patients fueling the investigation of more aggressive RT regimens. As the dose is increased and accelerated the volume of normal lung tissue treated becomes a limiting factor. Thus elimination of ENI followed by further dose escalation has become a commonly pursued solution. When ENI is excluded, treatment is restricted to clinically positive disease and negative lymph node stations are left untreated. RESULTS Radiographic and surgical data suggest our ability to determine the true extent of disease is imperfect and therefore the elimination of ENI likely leaves microscopic NSCLC untreated. CONCLUSIONS At our institution we have concluded that the prophylactic treatment of regional lymph nodes is best reserved for patients most likely to achieve local control and are designing treatment protocols including chemotherapy to take advantage of this improvement in local control.

Abstract
OBJECTIVES Twenty-three percent of white and 36% of African American patients who suffer from early stage non-small cell lung cancer do not undergo potentially curative surgery A simple decision model is presented to probe for elements of surgical decision making that could explain decisions against lung cancer surgery and racial variation in these decisions. METHODS A survey of 181 diverse individuals to measure health utility scores for conditions relevant to lung cancer surgery was performed. These scores were inserted into a simple model that calculates quality-adjusted survival related to decisions for and against cancer surgery RESULTS The health utility score (HUS) for progressive lung cancer, as determined by a survey using the standard gamble approach, is nearly twice as high in African Americans as whites (0.32 v. 0.18). However, in a model incorporating African American utility data, lung cancer surgery remains heavily favored compared to the no-surgery decision (2.32 v. 0.48 quality-adjusted life years). Sensitivity analysis shows that factors that lead to a belief of cancer "cure" in the absence of surgical intervention are much more important than variations of HUS in directing model results away from surgery. CONCLUSION This analysis illustrates that racial differences in quality-of-life ratings of progressive lung cancer as measured by HUS exist but may not explain decisions against surgery as much as other elements of patient care.

Abstract
To develop an evidence-based benchmark for the use of radiotherapy in lung cancer, we did a systematic review of treatment guidelines on radiotherapy for lung cancer. We then constructed an optimum use of radiotherapy "tree" from epidemiological data, which shows the proportion of patients with clinical attributes indicating that they would benefit from radiotherapy. We calculated that the proportion of patients with lung cancer in whom radiotherapy is indicated (according to the best available evidence) is 76%. We then compared this ideal rate with the actual rates of use of radiotherapy for lung cancer in Australia, and internationally, in the past decade. A substantial discrepancy was found between the evidence-based recommended rate of use and the actual rates reported in clinical practice. We hope this model will be used to plan efficient and cost-effective radiotherapy services.

Abstract
BACKGROUND The role of postoperative radiotherapy in the treatment of patients with completely resected non-small cell lung cancer was not clear. A systematic review and quantitative meta-analysis were therefore undertaken to evaluate the available evidence from randomised trials. OBJECTIVES To evaluate the effect of post-operative radiotherapy (PORT) on survival and recurrence in patients with completely resected non-small cell lung cancer. To investigate whether or not pre-defined patient sub-groups benefit more or less from PORT. SEARCH STRATEGY MEDLINE and CANCERLIT searches were supplemented by information from trial registers and by hand searching relevant meeting proceedings and by discussion with relevant trialists and organisations. SELECTION CRITERIA Both published and unpublished trials were eligible for inclusion provided the patients had undergone a complete resection; had been randomised between radiotherapy and no immediate further treatment; that the method of randomisation precluded prior knowledge of the treatment to be assigned; and that recruitment was between 1965 and 1995. DATA COLLECTION AND ANALYSIS A quantitative meta-analysis using updated information from individual patients from all available randomised trials was carried out. Data from all patients randomised in all eligible trials were sought directly from those responsible. Updated information on survival, recurrence and date of last follow up were obtained, as were details of treatment allocated, date of randomisation, age, sex, histological cell type, stage and performance status. To avoid potential bias, information was requested for all randomised patients including those who had been excluded from the investigators' original analyses. All analyses were done on intention to treat on the endpoints of survival and recurrence-free survival. Subgroup analyses by age, sex, histological cell type, tumour stage and performance status were also done. MAIN RESULTS 2128 patients from 9 trials were included (median follow-up of 3.9 years). The results show a significant adverse effect of PORT on survival with a hazard ratio of 1.21 or 21% relative increase in the risk of death. This is equivalent to an absolute detriment of 7% at 2 years (95% confidence interval 3 to 11%) reducing overall survival from 55% to 48%. Exploratory subgroup analyses suggested that this detrimental effect was most pronounced for patients with stage I/II, N0-N1 disease, whereas for stage III, N2 patients there was no clear evidence of an adverse effect. REVIEWER'S CONCLUSIONS PORT is detrimental to patients with early stage completely resected non-small cell lung cancer and should not be used in the routine treatment of such patients. The role of PORT in the treatment of N2 tumours is not clear and may justify further research. Since the publication of this review by the collaborative group in 2001, 1 additional trial has been published. The next update of the IPD meta-analysis will aim to include data from this trial.

Abstract
PURPOSE Some studies report a high risk of death from intercurrent disease (DID) after postoperative radiotherapy (XRT) for non-small-cell lung cancer (NSCLC). This study determines the risk of DID after modern-technique postoperative XRT. PATIENTS AND METHODS A total of 202 patients were treated with surgery and postoperative XRT for NSCLC. Most patients (97%) had pathologic stage II or III disease. Many patients (41%) had positive/close/uncertain resection margins. The median XRT dose was 55 Gy with fraction size of 1.8 to 2 Gy. The risk of DID was calculated actuarially and included patients who died of unknown/uncertain causes. Median follow-up was 24 months for all patients and 62 months for survivors. RESULTS A total of 25 patients (12.5%) died from intercurrent disease, 16 from confirmed noncancer causes and nine from unknown causes. The 4-year actuarial rate of DID was 13.5%. This is minimally increased compared with the expected rate for a matched population (approximately 10% at 4 years). On multivariate analysis, age and radiotherapy dose were borderline significant factors associated with a higher risk of DID (P =.06). The crude risk of DID for patients receiving less than 54 Gy was 2% (4-year actuarial risk 0%) versus 17% for XRT dose > or = 54 Gy. The 4-year actuarial overall survival was 34%; local control was 84%; and freedom from distant metastases was 37%. CONCLUSION Modern postoperative XRT for NSCLC does not excessively increase the risk of intercurrent deaths. Further study of postoperative XRT, particularly when using more sophisticated treatment planning and reasonable total doses, for carefully selected high-risk resected NSCLC is warranted.
