Abstract
OBJECTIVES In patients receiving concurrent chemoradiation for locally advanced non-small cell lung cancer (NSCLC), consolidation chemotherapy is frequently given even though several randomized trials have failed to show a benefit. We explored the potential benefits of consolidation chemotherapy using a population-based comparative effectiveness approach. MATERIALS AND METHODS Surveillance, Epidemiology, and End Results-Medicare was used to identify patients with Stage III NSCLC aged ≥65 and diagnosed 2002-2009. We selected patients who received concurrent chemoradiotherapy and determined whether they were (concurrent-consolidation) or were not (concurrent-alone) treated with consolidation chemotherapy. Outcomes were overall and cancer specific survival using a conditional landmark analysis approach. RESULTS 1688 patients treated with concurrent-alone or concurrent-consolidation were identified with a median follow up of 29 months. Choice of chemotherapy agents did not correlate with outcome. For concurrent-consolidation versus concurrent-alone, the median overall survival was 21 months versus 18 months, respectively (log-rank p=0.008) and the median cancer specific survival was 23 months versus 19 months, respectively (log-rank p=0.03). On multivariate analysis, concurrent-consolidation remained associated with improved overall survival (HR 0.85, p=0.04), and there was a trend for improved cancer specific survival (HR 0.87, p=0.12). Inverse probability of treatment weighting using propensity scores demonstrated similar findings. Importantly, the benefit of concurrent-consolidation held only for patients treated with carboplatin-taxane but not with cisplatin-etoposide. CONCLUSION Survival outcomes were similar among the five most commonly employed platinum-based doublets. We found that patients receiving cisplatin during radiation do not appear to benefit from additional chemotherapy. However, for patients receiving carboplatin, consolidation chemotherapy was associated with improved overall and cancer specific survival.

Late-Course Adaptive Adjustment Based on Metabolic Tumor Volume Changes during Radiotherapy May Reduce Radiation Toxicity in Patients with Non-Small Cell Lung Cancer. PLoS One 2017; 12:e0170901. [PMID: 28125698 PMCID: PMC5268643 DOI: 10.1371/journal.pone.0170901] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2016] [Accepted: 01/12/2017] [Indexed: 12/19/2022] Open
Abstract
To reduce the high risk of radiation toxicity and enhance the quality of life of patients with non-small cell lung cancer (NSCLC), we quantified the metabolic tumor volumes (MTVs) from baseline to the late-course of radiotherapy (RT) by fluorodeoxyglucose positron emission tomography computerized tomography (FDG PET-CT) and discussed the potential benefit of late-course adaptive plans rather than original plans by dose volume histogram (DVH) comparisons. Seventeen patients with stage II-III NSCLC who were treated with definitive conventionally fractionated RT were eligible for this prospective study. FDG PET-CT scans were acquired within 1 week before RT (pre-RT) and at approximately two-thirds of the total dose during-RT (approximately 40 Gy). MTVs were taken as gross tumor volumes (GTVs) that included the primary tumor and any involved hilar or mediastinal lymph nodes. An original plan based on the baseline MTVs and adaptive plans based on observations during-RT MTVs were generated for each patient. The DVHs for lung, heart, esophagus and spinal cord were compared between the original plans and composite plans at 66 Gy. At the time of approximately 40 Gy during-RT, MTVs were significantly reduced in patients with NSCLC (pre-RT 136.2±82.3 ml vs. during-RT 64.7±68.0 ml, p = 0.001). The composite plan of the original plan at 40 Gy plus the adaptive plan at 26 Gy resulted in better DVHs for all the organs at risk that were evaluated compared to the original plan at 66 Gy (p<0.05), including V5, V10, V15, V20, V25, V30 and the mean dose of total lung, V10, V20, V30, V40, V50, V60 and the mean dose of heart, V35, V40, V50, V55, V60, the maximum dose and mean dose of the esophagus, and the maximum dose of the spinal-cord. PET-MTVs were reduced significantly at the time of approximately 40 Gy during-RT. Late course adaptive radiotherapy may be an effective way to reduce the dose volume to the organs at risk, thus reducing radiation toxicity in patients with NSCLC.

DART-bid for loco-regionally advanced NSCLC : Summary of acute and late toxicity with long-term follow-up; experiences with pulmonary dose constraints. Strahlenther Onkol 2017; 193:315-323. [PMID: 28116446 PMCID: PMC5360836 DOI: 10.1007/s00066-016-1095-4] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/04/2016] [Accepted: 12/22/2016] [Indexed: 12/19/2022]
Abstract
Background To report acute and late toxicity with long-term follow-up, and to describe our experiences with pulmonary dose constraints. Methods Between 2002 and 2009, 150 patients with 155 histologically/cytologically proven non-small cell lung cancer (NSCLC; tumor stages II, IIIA, IIIB in 6, 55 and 39%, respectively) received the following median doses: primary tumors 79.2 Gy (range 72.0–90.0 Gy), lymph node metastases 59.4 Gy (54.0–73.8 Gy), nodes electively 45 Gy; with fractional doses of 1.8 Gy twice daily (bid). In all, 86% of patients received 2 cycles of chemotherapy previously. Results Five treatment-related deaths occurred: pneumonitis, n = 1; progressive pulmonary fibrosis in patients with pre-existing pulmonary fibrosis, n = 2; haemorrhage, n = 2. In all, 8% of patients experienced grade 3 and 1.3% grade 4 pneumonitis; 11% showed late fibrotic alterations grade 2 in lung parenchyma. Clinically relevant acute esophagitis (grade 2 and 3) was seen in 33.3% of patients, 2 patients developed late esophageal stenosis (G3). Patients with upper lobe, middle lobe and central lower lobe tumours (n = 130) were treated with V20 (total lung) up to 50% and patients with peripheral lower lobe tumours (n = 14, basal lateral tumours excluded) up to 42%, without observing acute or late pulmonary toxicity >grade 3. Only patients with basal lateral lower lobe tumours (n = 5) experienced grade 4/5 pulmonary toxicity; V20 for this latter group ranged between 30 and 53%. The mean lung dose was below the QUANTEC recommendation of 20–23 Gy in all patients. The median follow-up time of all patients is 26.3 months (range 2.9–149.4) and of patients alive 80.2 months (range 63.9–149.4.). The median overall survival time of all patients is 26.3 months; the 2-, 5- and 8‑year survival rates of 54, 21 and 15%, respectively. The local tumour control rate at 2 and 5 years is 70 and 64%, the regional control rate 90 and 88%, respectively. Discussion and conclusion Grade 4 or 5 toxicity occurred in 7/150 patients (4.7%), which can be partially avoided in the future (e.g. by excluding patients with pre-existing pulmonary fibrosis). Tolerance and oncologic outcome compare favourably to concomitant chemoradiation also in long-term follow-up.

Abstract
INTRODUCTION The integration between radiotherapy and drugs, from chemotherapy to recently available target therapies, continues to have a relevant role in the treatment of locally advanced and metastatic Non-small cell lung cancer (NSCLC). Aim of the present review is to evaluate the promising and emerging application of the best interaction between new drugs and new modalities of radiotherapy. Areas covered: We searched Medline, Google Scholar, PubMed, ProQuest Dissertation, and Theses databases for reports published in English. A study was included when it reported on cancer-related radiotherapy and included patients with NSCLC treated with chemo and/or target therapies. Review articles were excluded from the analysis. Expert commentary: Chemo-radiotherapy still represents the standard of choice in locally advanced NSCLC, while to date the addition of target therapies to chemo-radiotherapy did not demonstrate any robust advantage in this stage of disease. Considering the absence of randomized controlled trials, the role of target therapies in early stage adjuvant NSCLC is not yet recommended in clinical practice. On the contrary, in the setting of oligometastatic and oligoprogressive disease, new molecules demonstrated to be safe and effective, opening to a promising and emerging application of the best interaction between new drugs and new modalities of radiotherapy.

Abstract
BACKGROUND Standard care for patients with inoperable advanced non-small cell lung cancer (NSCLC) is concurrent chemoradiotherapy. The ideal concurrent chemotherapy regimen has not been determined. The aim of this study is to retrospectively analyze the efficacy and safety of concurrent radiotherapy with carboplatin/paclitaxel administrated every three weeks (PC three-week regimen) in inoperable advanced NSCLC and compare them with the results of cisplatin/etoposide. METHODS The 43 patients with inoperable advanced NSCLC receiving concurrent chemotherapy in Peking Union Medical College Hospital from January 2012 to June 2014 were enrolled and analyzed. Of them, 15 patients received carboplatin/paclitaxel with concurrent thoracic radiotherapy; the other 28 patients received cisplatin/etoposide. Clinical characteristic, efficacy and toxicity data were compared in these two groups. RESULTS For the overall population, the objective response rate (ORR) and disease control rate (DCR) were 41.9% and 90.7% respectively. The median progression free survival (PFS) was 10.6 months (95%CI: 7.4-13.8). And the median overall survival (OS) was 19.2 months (95%CI: 15.3-23.1). There were no significant differences in response rates (ORR: 33.3% vs 46.4%; DCR: 86.7% vs 92.9%, P=0.638), PFS (6.6 months vs 12.2 months, P=0.389), or OS (16.1 months vs 22.1 months, P=0.555) in either group. The adverse events were generally manageable and no treatment-related deaths occurred. CONCLUSIONS Compared with PE, PC three-week regimen concurrent thoracic radiotherapy for inoperable advanced NSCLC has the similar efficacy and acceptable toxicity profile, which can be used in clinical setting.
