Optimal timing of thoracic irradiation for limited stage small cell lung cancer: Current evidence and future prospects. World J Clin Oncol 2022; 13:116-124. [PMID: 35316927 PMCID: PMC8894269 DOI: 10.5306/wjco.v13.i2.116] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/08/2021] [Revised: 06/21/2021] [Accepted: 01/10/2022] [Indexed: 02/06/2023] Open
Abstract
Lung cancer is a global health concern as the leading cause of cancer related mortality worldwide. Small cell lung cancer (SCLC) poses a formidable challenge to the treating physicians with the worst prognosis among all lung cancers. However, limited stage SCLC (LS-SCLC) has a relatively better outcome with multimodality management. Efforts have been focused on optimal integration of treatment modalities to achieve an improved therapeutic ratio for patients with LS-SCLC. While chemotherapy and thoracic radiation therapy (TRT) are primary components of initial management for LS-SCLC, there is no consensus on optimal timing of TRT. Within this context, we herein provide a concise overview of current evidence and future prospects regarding the optimal timing of thoracic irradiation for LS-SCLC in light of the literature.

Effects of a Unique Combination of the Whole-Body Low Dose Radiotherapy with Inactivation of Two Immune Checkpoints and/or a Heat Shock Protein on the Transplantable Lung Cancer in Mice. Int J Mol Sci 2021; 22:6309. [PMID: 34208396 PMCID: PMC8231142 DOI: 10.3390/ijms22126309] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2021] [Revised: 06/09/2021] [Accepted: 06/10/2021] [Indexed: 11/25/2022] Open
Abstract
Non-small cell lung cancer (NSCLC) continues to be the leading cause of cancer death worldwide. Recently, targeting molecules whose functions are associated with tumorigenesis has become a game changing adjunct to standard anti-cancer therapy. As evidenced by the results of preclinical and clinical investigations, whole-body irradiations (WBI) with X-rays at less than 0.1-0.2 Gy per fraction can induce remissions of various neoplasms without inciting adverse side effects of conventional chemo- and radiotherapy. In the present study, a murine model of human NSCLC was employed to evaluate for the first time the anti-neoplastic efficacy of WBI combined with inactivation of CTLA-4, PD-1, and/or HSP90. The results indicate that WBI alone and in conjunction with the inhibition of the function of the cytotoxic T-lymphocyte antigen-4 (CTLA-4) and the programmed death-1 (PD-1) receptor immune checkpoints (ICs) and/or heat shock protein 90 (HSP90) markedly reduced tumorigenesis in mice implanted by three different routes with the syngeneic Lewis lung cancer cells and suppressed clonogenic potential of Lewis lung carcinoma (LLC1) cells in vitro. These results were associated with the relevant changes in the profile of pro- and anti-neoplastic immune cells recruited to the growing tumors and the circulating anti- and pro-inflammatory cytokines. In contrast, inhibition of the tested molecular targets used either separately or in combination with each other did not exert notable anti-neoplastic effects. Moreover, no significant synergistic effects were detected when the inhibitors were applied concurrently with WBI. The obtained results supplemented with further mechanistic explanations provided by future investigations will help design the effective strategies of treatment of lung and other cancers based on inactivation of the immune checkpoint and/or heat shock molecules combined with low-dose radiotherapy.

Abstract
Small-cell lung cancer (SCLC) represents about 15% of all lung cancers and is marked by an exceptionally high proliferative rate, strong predilection for early metastasis and poor prognosis. SCLC is strongly associated with exposure to tobacco carcinogens. Most patients have metastatic disease at diagnosis, with only one-third having earlier-stage disease that is amenable to potentially curative multimodality therapy. Genomic profiling of SCLC reveals extensive chromosomal rearrangements and a high mutation burden, almost always including functional inactivation of the tumour suppressor genes TP53 and RB1. Analyses of both human SCLC and murine models have defined subtypes of disease based on the relative expression of dominant transcriptional regulators and have also revealed substantial intratumoural heterogeneity. Aspects of this heterogeneity have been implicated in tumour evolution, metastasis and acquired therapeutic resistance. Although clinical progress in SCLC treatment has been notoriously slow, a better understanding of the biology of disease has uncovered novel vulnerabilities that might be amenable to targeted therapeutic approaches. The recent introduction of immune checkpoint blockade into the treatment of patients with SCLC is offering new hope, with a small subset of patients deriving prolonged benefit. Strategies to direct targeted therapies to those patients who are most likely to respond and to extend the durable benefit of effective antitumour immunity to a greater fraction of patients are urgently needed and are now being actively explored.

Abstract
INTRODUCTION The optimal dose and fractionation of thoracic radiotherapy (RT) for limited-disease small-cell lung cancer (LD-SCLC) remain controversial. This meta-analysis was performed to compare the efficacy and RT toxicity between twice-daily thoracic RT (45 Gy with 1.5 Gy twice daily) and higher-dose once-daily RT (60-72 Gy with 1.8 Gy/2 Gy once daily) administered with chemotherapy in LD-SCLC patients. METHODS PubMed, EMBASE, Web of Science, and the Cochrane Library were searched up to March 19, 2020 for studies that compared twice-daily thoracic RT (45 Gy with 1.5 Gy twice daily over 3 weeks) with higher-dose once-daily RT (60-72 Gy with 1.8 Gy/2 Gy once daily over 6-8 weeks) in LD-SCLC patients. RESULTS Five studies involving 13,726 patients were included in this analysis. Compared with the once-daily thoracic RT group, the 1-year overall survival (OS) rate (P < .001), the 2-year OS rate (P < .001), the 5-year OS rate (P < .001), the mOS (P < .001), and the 1-year LRFS rate (P = .048) were significantly improved in the twice-daily RT group. The toxic effects of RT (esophagitis: P = .293; pneumonitis: P = .103) were similar in both groups. CONCLUSION Compared with the higher-dose once-daily regimen, the twice-daily thoracic radiotherapy regimen improved efficacy but did not increase RT toxicity in LD-SCLC patients.

Abstract
BACKGROUND Lung cancers or (Bronchogenic-Carcinomas) are the disease in certain parts of the lungs in which irresistible multiplication of abnormal cells leads to the inception of a tumor. Lung cancers consisting of two substantial forms based on the microscopic appearance of tumor cells are: Non-Small-Cell-Lung-Cancer (NSCLC) (80 to 85%) and Small-Cell-Lung-Cancer (SCLC) (15 to 20%). DISCUSSION Lung cancers are existing luxuriantly across the globe and the most prominent cause of death in advanced countries (USA & UK). There are many causes of lung cancers in which the utmost imperative aspect is the cigarette smoking. During the early stage, there is no perspicuous sign/symptoms but later many symptoms emerge in the infected individual such as insomnia, headache, pain, loss of appetite, fatigue, coughing etc. Lung cancers can be diagnosed in many ways, such as history, physical examination, chest X-rays and biopsy. However, after the diagnosis and confirmation of lung carcinoma, various treatment approaches are existing for curing of cancer in different stages such as surgery, radiation therapy, chemotherapy, and immune therapy. Currently, novel techniques merged that revealed advancements in detection and curing of lung cancer in which mainly includes: microarray analysis, gene expression profiling. CONCLUSION Consequently, the purpose of the current analysis is to specify and epitomize the novel literature pertaining to the development of cancerous cells in different parts of the lung, various preeminent approaches of prevention, efficient diagnostic procedure, and treatments along with novel technologies for inhibition of cancerous cell growth in advance stages.

Abstract
At present, concurrent chemoradiotherapy (CRT) is considered the standard treatment of limited-stage small cell lung cancer (LS-SCLC). However, LS-SCLC is highly heterogeneous in the T stage, N stage, and prognosis. Increasing evidence has shown that individual treatment should be considered when treating LS-SCLC patients. The aim of the present study was to explore the optimal combination model of thoracic radiotherapy (TRT) and chemotherapy in N3 LS-SCLC. We retrospectively analyzed 93 N3 LS-SCLC patients treated in the Department of Oncology of Binzhou Medical University Hospital (Shandong, China) between March 2010 and October 2015. A total of 52 (52/93; 55.9%) patients received sequential CRT, and 41 (41/93; 44.1%) patients received concurrent CRT. All patients received 4-6 cycles of chemotherapy and TRT (50-60 Gy). The median follow-up time was 25.4 months (range was 6-65 months).The overall response rate was 88.5% in the sequential CRT group (9.6% complete response rate and 78.8% partial response rate) and 90.2% in the concurrent CRT group (14.6% complete response rate and 75.6% partial response rate). The PFS and OS were 15.4 months and 19.1 months in sequential CRT group, and 16.9 months and 20.5 months in concurrent CRT group. There was no significant difference in treatment response rate, PFS, and OS between sequential and concurrent CRT patients. The most common treatment-related toxicities were nausea/vomiting, neutropenia, and esophagitis. In conclusion, when concurrent CRT is performed in N3 LS-SCLC patients, tolerance to treatment should be fully considered. In our study, sequential CRT and concurrent CRT showed the same efficacy, and sequential CRT demonstrated better tolerance. However, these results require confirmation in future follow-up studies.

Abstract
The prevalence of small cell lung cancer (SCLC) has declined in the U.S. as the prevalence of tobacco use has declined. However, a significant number of people in the U.S. are current or former smokers and are at risk of developing SCLC. Routine histological or cytological evaluation can reliably make the diagnosis of SCLC, and immunohistochemistry stains (thyroid transcription factor-1, chromogranin, synaptophysin, and CD56) can be used if there is uncertainty about the diagnosis. Rarely do patients present with SCLC amendable to surgical resection, and evaluation requires a meticulous workup for extra-thoracic metastases and invasive staging of the mediastinum. Resected patients require adjuvant chemotherapy and/or thoracic radiation therapy (TRT), and prophylactic cranial radiation (PCI) should be considered depending on the stage. For limited-stage disease, concurrent platinum-etoposide and TRT followed by PCI is the standard. Thoracic radiation therapy should be started early in treatment, and can be given twice daily to 45 Gy or once daily to 60-70 Gy. For extensive-stage disease, platinum-etoposide remains the standard first-line therapy, and the standard second-line therapy is topotecan. Preliminary studies have demonstrated the activity of immunotherapy, and the response rate is approximately 10-30% with some durable responses observed. Rovalpituzumab tesirine, an antibody drug conjugate, has shown promising activity in patients with high delta-like protein 3 tumor expression (approximately 70% of patients with SCLC). The emergence of these and other promising agents has rekindled interest in drug development in SCLC. Several ongoing trials are investigating novel agents in the first-line, maintenance, and second-line settings. IMPLICATIONS FOR PRACTICE This review will provide an update on the standard therapies for surgically resected limited-stage small cell lung cancer and extensive-stage small cell lung cancer that have been investigated in recent clinical trials.

Abstract
BACKGROUND Concurrent chemoradiotherapy is the standard of care in limited-stage small-cell lung cancer, but the optimal radiotherapy schedule and dose remains controversial. The aim of this study was to establish a standard chemoradiotherapy treatment regimen in limited-stage small-cell lung cancer. METHODS The CONVERT trial was an open-label, phase 3, randomised superiority trial. We enrolled adult patients (aged ≥18 years) who had cytologically or histologically confirmed limited-stage small-cell lung cancer, Eastern Cooperative Oncology Group performance status of 0-2, and adequate pulmonary function. Patients were recruited from 73 centres in eight countries. Patients were randomly assigned to receive either 45 Gy radiotherapy in 30 twice-daily fractions of 1·5 Gy over 19 days, or 66 Gy in 33 once-daily fractions of 2 Gy over 45 days, starting on day 22 after commencing cisplatin-etoposide chemotherapy (given as four to six cycles every 3 weeks in both groups). The allocation method used was minimisation with a random element, stratified by institution, planned number of chemotherapy cycles, and performance status. Treatment group assignments were not masked. The primary endpoint was overall survival, defined as time from randomisation until death from any cause, analysed by modified intention-to-treat. A 12% higher overall survival at 2 years in the once-daily group versus the twice-daily group was considered to be clinically significant to show superiority of the once-daily regimen. The study is registered with ClinicalTrials.gov (NCT00433563) and is currently in follow-up. FINDINGS Between April 7, 2008, and Nov 29, 2013, 547 patients were enrolled and randomly assigned to receive twice-daily concurrent chemoradiotherapy (274 patients) or once-daily concurrent chemoradiotherapy (273 patients). Four patients (one in the twice-daily group and three in the once-daily group) did not return their case report forms and were lost to follow-up; these patients were not included in our analyses. At a median follow-up of 45 months (IQR 35-58), median overall survival was 30 months (95% CI 24-34) in the twice-daily group versus 25 months (21-31) in the once-daily group (hazard ratio for death in the once daily group 1·18 [95% CI 0·95-1·45]; p=0·14). 2-year overall survival was 56% (95% CI 50-62) in the twice-daily group and 51% (45-57) in the once-daily group (absolute difference between the treatment groups 5·3% [95% CI -3·2% to 13·7%]). The most common grade 3-4 adverse event in patients evaluated for chemotherapy toxicity was neutropenia (197 [74%] of 266 patients in the twice-daily group vs 170 [65%] of 263 in the once-daily group). Most toxicities were similar between the groups, except there was significantly more grade 4 neutropenia with twice-daily radiotherapy (129 [49%] vs 101 [38%]; p=0·05). In patients assessed for radiotherapy toxicity, was no difference in grade 3-4 oesophagitis between the groups (47 [19%] of 254 patients in the twice-daily group vs 47 [19%] of 246 in the once-daily group; p=0·85) and grade 3-4 radiation pneumonitis (4 [3%] of 254 vs 4 [2%] of 246; p=0·70). 11 patients died from treatment-related causes (three in the twice-daily group and eight in the once-daily group). INTERPRETATION Survival outcomes did not differ between twice-daily and once-daily concurrent chemoradiotherapy in patients with limited-stage small-cell lung cancer, and toxicity was similar and lower than expected with both regimens. Since the trial was designed to show superiority of once-daily radiotherapy and was not powered to show equivalence, the implication is that twice-daily radiotherapy should continue to be considered the standard of care in this setting.

Prognostic role of patient gender in limited-disease small-cell lung cancer treated with chemoradiotherapy. Strahlenther Onkol 2016; 193:150-155. [PMID: 27853828 DOI: 10.1007/s00066-016-1073-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2016] [Accepted: 10/19/2016] [Indexed: 01/22/2023]
Abstract
BACKGROUND Previous studies have demonstrated that female gender could be a prognostic factor in limited-disease (LD) small-cell lung cancer (SCLC), but the correlation between patient gender and survival parameters remains unclear. PATIENTS AND METHODS Data from 179 LD SCLC patients treated with definitive chemoradiotherapy (CRT) were reviewed. Influence of patient gender on time to progression (TTP), local control (LC), brain metastasis-free (BMFS), distant metastasis-free (DMFS) and overall survival (OS) was analysed. RESULTS Definitive CRT was completed by 179 (110 men/69 women) patients. Of these, 68 (38%; 34 men/34 women) patients were treated in concurrent and 111 (62%; 76 men/35 women) in sequential mode. Prophylactic cranial irradiation (PCI) was subsequently applied in 70 (39%; 36 men/34 women) patients with partial or complete response after CRT. Median OS was 20 (95% confidence interval [CI] 10-22) and 14 (95% CI 10-18) months in female and male patients, respectively (p = 0.021). In subgroups defined by remission status (complete and partial response) after CRT, an OS benefit for females compared to males was also detected. There was no correlation between patient gender and TTP, LC or DMFS, and no difference in OS in the female and male subgroups treated with PCI. The incidence of metachronous brain metastases (BMs) in the male and female subgroups differed significantly (40/110 men vs. 18/69 women, p = 0.03). Also, mean BMFS was significantly longer in women (p = 0.023). Patient gender also significantly correlated with OS on multivariate analysis after adjustment for other prognostic factors (p = 0.04, HR 1.38, 95% CI 1.08-1.92). CONCLUSION In this heterogeneous LD SCLC patient cohort treated with definitive CRT, female gender was significantly associated with longer BMFS and OS, as well as with a lower incidence of metachronous brain failure.

Abstract
Background: Chemoradiotherapy (CRT) is a treatment standard in limited disease (LD) small cell lung cancer (SCLC). Currently, the timing of thoracic radiation therapy (TRT) remains the subject of randomised trials and meta-analyses. To investigate a correlation between CRT schedule parameters and overall survival (OS) in a real-life patient cohort, a temporal analysis was performed. Methods: 182 LD SCLC patients successfully treated with definitive CRT were retrospectively reviewed. TRT was applied concurrently or sequentially. Impact of the treatment mode and interval of simultaneous treatment (IST) (an interval in days when chemotherapy and TRT were applied simultaneously, including time between chemotherapy cycles and weekends) on OS was analysed. Results: 71 (39%) patients were treated with concurrent and 111 (61%) with sequential CRT. Median overall survival (MS) for the entire cohort was 534 days (95%CI 461 - 607) without any significant difference between the concurrent and sequential groups (589: 95%CI 358 - 820 vs. 533: 95%CI 446 - 620 days, p=0.746, log-rank test). IST was 0 days in 111 (61%) patients treated sequentially whereas in the concurrent group, 20 (11%) and 51 (28%) patients showed an IST < 35 and > 35 days, respectively. Patients with IST > 0 and < 35 days demonstrated a trend to improved overall survival (MS: IST 0 vs. > 35 vs. < 35 was 533 vs. 448 vs. 1169 days, p=0.109, log-rank test). When patients treated with sequential CRT (IST 0) were excluded from the analysis, statistical difference in overall survival according to the IST subgroups (IST > 35 vs. < 35) became significant (p=0.021, log-rank test). On multivariate analysis of patients treated with concurrent CRT, IST > 0 and < 35 days remained a variable that significantly correlated with better overall survival (p=0.039, HR 0.38). Conclusion: In this real-life LD SCLC patient cohort, improved overall survival was achieved in patients treated with CRT schedule according to the IST > 0 and < 35-day concept. By exceeding the 35-day interval, we have seen deterioration in survival.

Impact of thoracic radiotherapy timing in limited-stage small-cell lung cancer: usefulness of the individual patient data meta-analysis. Ann Oncol 2016; 27:1818-28. [PMID: 27436850 PMCID: PMC5035783 DOI: 10.1093/annonc/mdw263] [Citation(s) in RCA: 69] [Impact Index Per Article: 8.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/27/2016] [Revised: 06/24/2016] [Accepted: 06/28/2016] [Indexed: 02/06/2023] Open
Abstract
BACKGROUND Chemotherapy (CT) combined with radiotherapy is the standard treatment of 'limited-stage' small-cell lung cancer. However, controversy persists over the optimal timing of thoracic radiotherapy and CT. MATERIALS AND METHODS We carried out a meta-analysis of individual patient data in randomized trials comparing earlier versus later radiotherapy, or shorter versus longer radiotherapy duration, as defined in each trial. We combined the results from trials using the stratified log-rank test to calculate pooled hazard ratios (HRs). The primary outcome was overall survival. RESULTS Twelve trials with 2668 patients were eligible. Data from nine trials comprising 2305 patients were available for analysis. The median follow-up was 10 years. When all trials were analysed together, 'earlier or shorter' versus 'later or longer' thoracic radiotherapy did not affect overall survival. However, the HR for overall survival was significantly in favour of 'earlier or shorter' radiotherapy among trials with a similar proportion of patients who were compliant with CT (defined as having received 100% or more of the planned CT cycles) in both arms (HR 0.79, 95% CI 0.69-0.91), and in favour of 'later or longer' radiotherapy among trials with different rates of CT compliance (HR 1.19, 1.05-1.34, interaction test, P < 0.0001). The absolute gain between 'earlier or shorter' versus 'later or longer' thoracic radiotherapy in 5-year overall survival for similar and for different CT compliance trials was 7.7% (95% CI 2.6-12.8%) and -2.2% (-5.8% to 1.4%), respectively. However, 'earlier or shorter' thoracic radiotherapy was associated with a higher incidence of severe acute oesophagitis than 'later or longer' radiotherapy. CONCLUSION 'Earlier or shorter' delivery of thoracic radiotherapy with planned CT significantly improves 5-year overall survival at the expense of more acute toxicity, especially oesophagitis.

Abstract
Background The role of remission status in limited disease (LD) small-cell lung cancer (SCLC) patients treated with definitive chemoradiotherapy (CRT) remains to be finally clarified. Methods Individual data from 184 patients treated with definitive CRT concurrently or sequentially were retrospectively reviewed. Kaplan-Meier analysis as well as univariate and multivariate Cox regression models were used to describe survival within patient subgroups defined by remission status. Results 71 (39 %) patients were treated in the concurrent, 113 (61 %) in the sequential CRT mode. Prophylactic cranial irradiation (PCI) was applied in 71 (39 %) patients. 37 (20 %) patients developed local, while 89 (48 %) distant recurrence. 58 (32 %) patients developed metachronous brain metastases. Complete, partial remission and non-response (defined as stable and progressive disease) were documented in 65 (35 %), 77 (42 %), and 37 (20 %) patients, respectively. In complete responders median overall survival was 21.8 months (95CI: 18.6 – 25) versus 14.9 (95 % CI: 11.7 – 18.2) (p = 0.041, log-rank test) and 11.5 months (95 % CI: 8.9 – 15.0) (p < 0.001, log-rank test) in partial and non-responders, respectively. The same effect was documented for the time to progression and distant metastasis-free survival. In the multivariate analysis achievement of complete remission as a variable shows a trend for the prolonged time to progression (p = 0.1, HR 1.48) and distant metastasis-free survival (p = 0.06, HR 1.63) compared to partial responders and was highly significant compared to non-responders. Conclusion In this treated heterogeneous LD SCLC patient cohort complete remission was associated with longer time to progression, distant metastasis-free and overall survival compared to the non- and especially partial responders.

Abstract
Small cell lung cancer (SCLC) is an aggressive neuroendocrine malignancy with a unique natural history characterized by a short doubling time, high growth fraction, and early development of widespread metastases. Although a chemotherapy- and radiation-sensitive disease, SCLC typically recurs rapidly after primary treatment, with only 6% of patients surviving 5 years from diagnosis. This disease has been notable for the absence of major improvements in its treatment: Nearly four decades after the introduction of a platinum-etoposide doublet, therapeutic options have remained virtually unchanged, with correspondingly little improvement in survival rates. Here, we summarize specific barriers and challenges inherent to SCLC research and care that have limited progress in novel therapeutic development to date. We discuss recent progress in basic and translational research, especially in the development of mouse models, which will provide insights into the patterns of metastasis and resistance in SCLC. Opportunities in clinical research aimed at exploiting SCLC biology are reviewed, with an emphasis on ongoing trials. SCLC has been described as a recalcitrant cancer, for which there is an urgent need for accelerated progress. The NCI convened a panel of laboratory and clinical investigators interested in SCLC with a goal of defining consensus recommendations to accelerate progress in the treatment of SCLC, which we summarize here.

Abstract
Small cell lung cancer is staged as either limited (potentially curable) or extensive (incurable), based on the extent of disease in the chest. Limited stage disease is treated with concurrent chemotherapy and thoracic radiotherapy followed by prophylactic cranial irradiation (PCI). The conventional approach to extensive disease is chemotherapy only, with radiotherapy reserved for site-specific palliation. Recent reports suggest increasing applications for radiotherapy. The administration of PCI to extensive stage patients demonstrating response to chemotherapy is now recommended due to local control and overall survival benefits. Likewise, the role of consolidation chest radiotherapy after chemotherapy for advanced disease patients has seen a resurgence of interest in light of a recent publication suggesting improved local benefits which may influence survival. Recent technical advances in radiotherapy such as stereotactic body treatment and intensity-modulated therapy may also provide new indications for radiation, to enhance delivery and minimize toxicities.

Abstract
INTRODUCTION Concurrent ONce-daily VErsus twice-daily RadioTherapy (CONVERT) is the only multicentre, international, randomised, phase III trial open in Europe and Canada looking at optimisation of chemoradiotherapy (RT) in limited stage small cell lung cancer (LS-SCLC). Following on from the Turrisi trial of once-daily versus twice-daily (BD) concurrent chemoradiotherapy, there is a real need for a new phase III trial using modern conformal RT techniques and investigating higher once-daily radiation dose. This trial has the potential to define a new standard chemo-RT regimen for patients with LS-SCLC and good performance status. METHODS AND ANALYSIS 447 patients with histologically or cytologically proven diagnosis of SCLC were recruited from 74 centres in eight countries between 2008 and 2013. Patients were randomised to receive either concurrent twice-daily RT(45 Gy in 30 twice-daily fractions over 3 weeks) or concurrent once-daily RT(66 Gy in 33 once-daily fractions over 6.5 weeks) both starting on day 22 of cycle 1. Patients are followed up until death. The primary end point of the study is overall survival and secondary end points include local progression-free survival, metastasis-free survival, acute and late toxicity based on the Common Terminology Criteria for Adverse Events V.3.0, chemotherapy and RTdose intensity. ETHICS AND DISSEMINATION The trial received ethical approval from NRES Committee North West-Greater Manchester Central (07/H1008/229). There is a trial steering committee, including independent members and an independent data monitoring committee. Results will be published in a peer-reviewed journal and presented at international conferences. TRIAL REGISTRATION NUMBER ISRCTN91927162; Pre-results.

Abstract
Approximately 10% of small cell lung cancer (SCLC) cases develop superior vena cava syndrome (SVCS). Many SCLC patients with SVCS have relatively limited disease, requiring curative rather than palliative treatment. Besides chemotherapy, radiotherapy is important for treating SCLC with SVCS. We retrospectively evaluated the influence of radiotherapy dose on the prognosis of 57 patients with SCLC with SVCS treated with concurrent chemoradiotherapy. The mean biological equivalent radiation dose was 71.5 Gy. We administered etoposide/cisplatin as sequential and concurrent chemotherapy. All patients received at least one cycle of concurrent chemotherapy. All patients had partial or complete response; SVCS-associated symptoms were reduced in 87.7% (50/57) of patients within 3-10 days after treatment. Radiation dose did not affect 2-year local control (74.2% vs. 80.8%). Patients who received high-dose radiation had a lower 2-year overall survival rate than those who received low-dose radiation (11.6 vs. 33%; P = 0.024). The high dose group median survival was 15.0 months (95% confidence interval [CI]: 11.2-19.0) compared with 18.7 months (95% CI: 13.9-23.6) in the low dose group. Grade 3/4 neutropenia occurred in 22/26 high dose patients (84.6%) and 21/31 low dose patients (67.7%). In the high dose group, 30.8% of patients had grade 3/4 esophagitis compared with 19.4% of low dose patients. Only 29.0% of low dose patients received < 4 cycles of chemotherapy in the first 12 weeks after treatment began compared with 46.2% of high dose patients. Concurrent chemoradiotherapy is a tolerable modality for treating stage IIIA/IIIB SCLC with SVCS. Moderate-dose radiotherapy is preferable.

Abstract
Small cell lung cancer (SCLC) is an aggressive disease that accounts for approximately 14% of all lung cancers. In the United States, approximately 31,000 patients are diagnosed annually with SCLC. Despite numerous clinical trials, including at least 40 phase 3 trials since the 1970s, systemic treatment for patients with SCLC has not changed significantly in the past several decades. Consequently, the 5-year survival rate remains low at <7% overall, and most patients survive for only 1 year or less after diagnosis. Unlike nonsmall cell lung cancer (NSCLC), in which major advances have been made using targeted therapies, there are still no approved targeted drugs for SCLC. Significant barriers to progress in SCLC include 1) a lack of early detection modalities, 2) limited tumor tissue for translational research (eg, molecular profiling of DNA, RNA, and/or protein alterations) because of small diagnostic biopsies and the rare use of surgical resection in standard treatment, and 3) rapid disease progression with poor understanding of the mechanisms contributing to therapeutic resistance. In this report, the authors review the current state of SCLC treatment, recent advances in current understanding of the underlying disease biology, and opportunities to advance translational research and therapeutic approaches for patients with SCLC.

Abstract
Purpose To analyze the feasibility of omitting clinical target volume (CTV) for limited small cell lung cancer treated with chemotherapy and intensity modulated radiotherapy. Methods and materials 89 patients were treated from January 1, 2008 to August 31, 2011, 54 cases were irradiated with target volume without CTV, and 35 cases were irradiated with CTV. Both arms were irradiated post chemotherapy tumor extent and omitted elective nodal irradiation; dose prescription was 95% PTV56-63 Gy/28-35 F/5.6-7 weeks. Results In the arm without CTV and arm with CTV, the local relapse rates were 16.7% and 17.1% (p = 0.586) respectively. In the arm without CTV, of the 9 patients with local relapse, 6 recurred in-field, 2 recurred in margin, 1 recurred out of field. In the arm with CTV, of the 6 patients with local relapse, 4 recurred in-field, 1 recurred in margin, 1 recurred out of field. The distant metastases rates were 42.6% and 51.4% (p = 0.274) respectively. Grade 3-4 hematological toxicity and radiation esophagitis had no statistically significant, but grade 3-4 radiation pneumonia was observed in only 7.4% in the arm without CTV, compared 22.9% in the arm with CTV (p = 0.040). The median survival in the arm without CTV had not reached, compared with 38 months in the with CTV arm. The l- years, 2- years, 3- years survival rates of the arm without CTV and the arm with CTV were 81.0%, 66.2%, 61.5% and 88.6%, 61.7%, 56.6% (p = 0.517). The multivariate analysis indicated that the distant metastases (p = 0.000) and PCI factor (p = 0.004) were significantly related to overall survival. Conclusions Target delineation omitting CTV for limited-disease small cell lung cancer received IMRT was feasible. The distant metastases and PCI factor were significantly related to overall survival.

BACKGROUND/AIMS Chemotherapy combined with radiation therapy is the standard treatment for limited stage small cell lung cancer (LS-SCLC). Although numerous studies indicate that the overall duration of chemoradiotherapy is the most relevant predictor of outcome, the optimal chemotherapy and radiation schedule for LS-SCLC remains controversial. Therefore we analyzed the time from the start of any treatment until the end of radiotherapy (SER) in patients with LS-SCLC. METHODS We retrospectively analyzed 29 patients diagnosed histologically with LS-SCLC and divided them into two groups: a short SER group (< 60 days) and a long SER (> 60 days) group. Patients were treated with irinotecan-based chemotherapy and thoracic radiotherapy. RESULTS Sixteen patients were in the short SER group and 13 patients were in the long SER group. Short SER significantly prolonged survival rate (p = 0.03) compared with that of long SER. However, no significant differences in side effects were observed. CONCLUSIONS Short SER should be considered to improve the outcome of concurrent chemoradiotherapy for LS-SCLC.

Abstract
OPINION STATEMENT Small-cell lung cancers are aggressive tumors, often discovered with widespread metastases that include brain involvement. For patients with limited-stage disease, the standard of care is platinum-doublet chemotherapy (often etoposide) with concurrent radiation. Concurrent chemoradiotherapy can be difficult when given upfront, sometimes preventing on-time completion of later chemotherapy cycles. Recent data support giving concurrent chemoradiotherapy following 1 or 2 cycles of chemotherapy alone. For patients with extensive disease, chemotherapy alone remains the standard of care. For patients with limited or extensive disease who achieve clinical benefit from primary therapy, consideration of prophylactic cranial radiation should be made. Despite aggressive use of these treatments, most patients will have life-threatening disease return, sometimes very soon after finishing treatment. For those patients who are candidates for additional systemic treatment, several single-agent options exist, such as topotecan, paclitaxel, or even consideration of retreating with the same initial regimen depending on how effective it was. All patients with SCLC should be considered for clinical trials, because this remains our greatest hope for finding more effective therapies.

Abstract
PURPOSE To investigate whether high-dose thoracic radiation given twice daily during cisplatin-etoposide chemotherapy for limited small-cell lung cancer (LSCLC) improves survival, acute esophagitis, and local control rates relative to findings from Intergroup trial 0096 (47%, 27%, and 64%). PATIENTS AND METHODS Patients were accrued over a 3-year period from 22 US and Canadian institutions. Patients with LSCLC and good performance status were given thoracic radiation to 61.2 Gy over 5 weeks (daily 1.8-Gy fractions on days 1-22, then twice-daily 1.8-Gy fractions on days 23-33). Cisplatin (60 mg/m(2) IV) was given on day 1 and etoposide (120 mg/m(2) IV) on days 1-3 and days 22-24, followed by 2 cycles of cisplatin plus etoposide alone. Patients who achieved complete response were offered prophylactic cranial irradiation. Endpoints included overall and progression-free survival; severe esophagitis (Common Toxicity Criteria v 2.0) and treatment-related fatalities; response (Response Evaluation Criteria in Solid Tumors); and local control. RESULTS Seventy-two patients were accrued from June 2003 through May 2006; 71 were evaluable (median age 63 years; 52% female; 58% Zubrod 0). Median survival time was 19 months; at 2 years, the overall survival rate was 36.6% (95% confidence interval [CI] 25.6%-47.7%), and progression-free survival 19.7% (95% CI 11.4%-29.6%). Thirteen patients (18%) experienced severe acute esophagitis, and 2 (3%) died of treatment-related causes; 41% achieved complete response, 39% partial response, 10% stable disease, and 6% progressive disease. The local control rate was 73%. Forty-three patients (61%) received prophylactic cranial irradiation. CONCLUSIONS The overall survival rate did not reach the projected goal; however, rates of esophagitis were lower, and local control higher, than projected. This treatment strategy is now one of three arms of a prospective trial of chemoradiation for LSCLC (Radiation Therapy Oncology Group 0538/Cancer and Leukemia Group B 30610).

Abstract
BACKGROUND AND PURPOSE Limited data concerning treatment-related prognostic factors in limited disease (LD) small-cell lung cancer (SCLC) patients with poor initial performance status (PS) who successfully completed chemoradiotherapy (CRT) are available. PATIENTS AND METHODS A total of 125 patients with initial PS WHO 2-3 who successfully completed CRT were retrospectively reviewed. Thoracic radiation therapy (TRT) was applied in the concurrent (group 1) or sequential (group 2) mode. Influence of treatment type, time from diagnosis to start of TRT, number of chemotherapy cycles, prophylactic cranial irradiation (PCI), occurrence of brain metastases (BMs), and duration of CRT on overall survival (OS) were analyzed. RESULTS Median duration of CRT was 156 days in group 1 and 195 days in group 2 (p < 0.001). Median progression-free survival and OS were 11.6 (95% confidence interval (CI) 10-13.2) and 14.9 (95% CI 11.7-17.6) months with no difference between the groups. The 2- and 3-year survival rates were 37.9 ± 6.9% and 22.7 ± 6.3% in group 1 and 22.4 ± 4.9% and 15.2 ± 4.3% in group 2, respectively. Duration of CRT was only treatment-related factor predicting OS in the uni- (p < 0.014) and multivariate (p < 0.025) analyses. Short dose-dense CRT was associated with improved OS. CONCLUSION Duration of CRT affects OS in LD SCLC patients with poor initial performance status who successfully completed multimodality treatment.

Abstract
Small-cell lung cancer (SCLC) is a disease with a poor prognosis and limited treatment options. Over the past 30 years, basic and clinical research have translated to little innovation in the treatment of this disease. The Study of Picoplatin Efficacy After Relapse (SPEAR) evaluated best supportive care with or without picoplatin for second-line SCLC treatment and failed to meet its primary end point of overall survival. As the largest second-line, randomized study in patients with SCLC, SPEAR provides an opportunity to critically examine the drug development model in this disease. In this Review, we discuss the current standard approach for the management of SCLC that progresses after first-line therapy, analyze the preliminary data that supported the evaluation of picoplatin in this setting, and critically evaluate the SPEAR trial design and results. Lastly, we present advances in the understanding of the molecular biology of SCLC that could potentially inform future clinical trials and hopefully lead to the successful development of molecular targeted agents for the treatment of this disease.

Abstract
BACKGROUND Many patients with stage I-III small cell lung cancer (SCLC) experience disease progression short after the completion of concurrent chemoradiotherapy (CRT). The purpose of the current study was to evaluate whether CT or FDG metabolic response early after the start of chemotherapy, but before the beginning of chest RT, is predictive for survival in SCLC. METHODS Fifteen stage I-III SCLC patients treated with concurrent CRT with an FDG-PET and CT scan available before the start of chemotherapy and after or during the first cycle of chemotherapy, but before the start of radiotherapy, were selected. The metabolic volume (MV) was defined both within the primary tumour and in the involved nodal stations using the 40% (MV40) and 50% (MV50) threshold of the maximum SUV. Metabolic and CT response was assessed by the relative change in MV and CT volume, respectively, between both time points. The association between response and overall survival (OS) was analysed by univariate cox regression analysis. The minimum follow-up was 18 months. RESULTS Reductions in MV40 and MV50 were -36±38% (126.4 to 68.7cm(3)) and -44±38% (90.2 to 27.8cm(3)), respectively. The median CT volume reduction was -40±64% (190.6 to 113.8cm(3)). MV40 and MV50 changes showed a significant association with survival (HR=1.02, 95% CI: 1.00-1.04 (p=0.042); HR=1.02, 95% CI: 1.00-1.04 (p=0.048), respectively), indicating a 2% increase in survival probability for 1% reduction in metabolic volume. The CT volume change was also significantly correlated with survival (HR=1.01, 95% CI: 1.00-1.03, p=0.007). CONCLUSIONS This hypothesis generating study shows that both the early CT and the MV changes show a significant correlation with survival in SCLC. A prospective study is planned in a larger patient cohort to allow multivariate analysis, with the final aim to select patients early during treatment that could benefit from dose intensification or alternative treatment.

Abstract
In the U.S., the prevalence of small cell lung cancer (SCLC) is declining, probably reflecting the decreasing prevalence of tobacco use. However, a significant number of patients will receive a diagnosis of SCLC, and approximately 40% of patients with SCLC will have limited-stage (LS) disease, which is potentially curable with the combination of chemotherapy and radiation therapy. The standard therapy for LS-SCLC is concurrent chemoradiotherapy, and the 5-year survival rate observed in clinical trials is approximately 25%. The standard chemotherapy remains cisplatin and etoposide, but carboplatin is frequently used in patients who cannot tolerate or have a contraindication to cisplatin. Substantial improvements in survival have been made through improvements in radiation therapy. Concurrent chemoradiotherapy is the preferred therapy for patients who are appropriate candidates. The optimal timing of concurrent chemoradiotherapy is during the first or second cycle, based on data from meta-analyses. The optimal radiation schedule and dose remain topics of debate, but 1.5 Gy twice daily to a total of 45 Gy and 1.8-2.0 Gy daily to a total dose of 60-70 Gy are commonly used treatments. For patients who obtain a near complete or complete response, prophylactic cranial radiation reduces the incidence of brain metastases and improves overall survival. The ongoing Radiation Therapy Oncology Group and Cancer and Leukemia Group B and the European and Canadian phase III trials will investigate different radiation treatment paradigms for patients with LS-SCLC, and completion of these trials is critical.

Abstract
BACKGROUND The societal burden of lung cancer is high because of its high incidence and high lethality. From a theoretical point of view, radiotherapy with beams of protons and heavier charged particles, for example, carbon ions (C-ions), should lead to superior results, compared with photon beams. In this review, we searched for clinical evidence to justify implementation of particle therapy as standard treatment in lung cancer. METHODS A systematic literature review based on an earlier published comprehensive review was performed and updated through November 2009. RESULTS Eleven fully published studies, all dealing with non-small cell lung cancer (NSCLC), mainly stage I, were identified. No phase III trials were found. For proton therapy, 2- to 5-year local tumor control rates varied in the range of 57%-87%. The 2- and 5-year overall survival (OS) and 2- and 5-year cause-specific survival (CSS) rates were 31%-74% and 23% and 58%-86% and 46%, respectively. Radiation-induced pneumonitis was observed in about 10% of patients. For C-ion therapy, the overall local tumor control rate was 77%, but it was 95% when using a hypofractionated radiation schedule. The 5-year OS and CSS rates were 42% and 60%, respectively. Slightly better results were reported when using hypofractionation, 50% and 76%, respectively. CONCLUSION The present results with protons and heavier charged particles are promising. However, the current lack of evidence on the clinical (cost-)effectiveness of particle therapy emphasizes the need to investigate the efficiency of particle therapy in an adequate manner. Until these results are available for lung cancer, charged particle therapy should be considered experimental.

Abstract
INTRODUCTION To determine the 1-year survival, response rate, and toxicity for patients with limited stage small cell lung cancer treated with the combination of cisplatin plus etoposide plus paclitaxel with delayed concurrent (starting with cycle 3) high dose thoracic radiotherapy. PATIENTS AND METHODS Patients with previously untreated limited stage small cell lung cancer, Easter Cooperative Oncology Group performance status of 0-2 and adequate organ function were eligible. Cycles 1 and 2 of chemotherapy consisted of paclitaxel 170 mg/m intravenous day 1, etoposide 80 mg/m intravenous days 1 to 3, and cisplatin 60 mg/m intravenous day 1 followed by filgrastim 5 microg/kg subcutaneously days 4 to 13. Cycles 3 and 4 of chemotherapy consisted of a reduced dose of paclitaxel 135 mg/m intravenous day 1, and the same dose of etoposide and cisplatin with concurrent thoracic radiation therapy 1.8 Gy in 35 fractions (total 63 Gy) administered over 7 weeks. RESULTS Sixty-three patients were entered, 61 patients were eligible. The most common grade 4 toxicity seen was granulocytopenia (62%). Nonhematologic toxicities included febrile neutropenia in 19% of patients, grade 3 and 4 esophagitis in 32% of patients, and grade 3 peripheral neuropathy in 14% of patients. Two patients suffered lethal toxicities. The overall response rate was 79%. The 1-year survival rate was 64%. The median overall survival was 15.7 months, and the median progression-free survival was 8.6 months. CONCLUSIONS The combination of cisplatin plus etoposide plus paclitaxel chemotherapy and concurrent delayed thoracic radiotherapy as administered in this trial provide no apparent advantage with respect to response, local control, or survival compared with historical controls.

Abstract
This randomised trial compared platinum-based to anthracycline-based chemotherapy in patients with small-cell lung cancer (limited or extensive stage) and <or=2 adverse prognostic factors. Patients were randomised to receive six cycles of either ACE (doxorubicin 50 mg/m(2) i.v., cyclophosphamide 1 g/m(2) i.v. and etoposide 120 mg/m(2) i.v. on day 1, then etoposide 240 mg/m(2) orally for 2 days) or PE (cisplatin 80 mg/m(2) and etoposide 120 mg/m(2) i.v. on day 1, then etoposide 240 mg/m(2) orally for 2 days) given for every 3 weeks. For patients where cisplatin was not suitable, carboplatin (AUC6) was substituted. A total of 280 patients were included (139 ACE, 141 PE). The response rates were 72% for ACE and 77% for PE. One-year survival rates were 34 and 38% (P=0.497), respectively and 2-year survival was the same (12%) for both arms. For LD patients, the median survival was 10.9 months for ACE and 12.6 months for PE (P=0.51); for ED patients median survival was 8.3 months and 7.5 months, respectively. More grades 3 and 4 neutropenia (90 vs 57%, P<0.005) and grades 3 and 4 infections (73 vs 29%, P<0.005) occurred with ACE, resulting in more days of hospitalisation and greater i.v. antibiotic use. ACE was associated with a higher risk of neutropenic sepsis than PE and with a trend towards worse outcome in patients with LD, and should not be studied further in this group of patients.

Abstract
Small-cell lung cancer accounts for up to one-fifth of all lung cancers diagnosed. While the response rates to chemotherapy are high, ultimately the majority of patients will relapse and die from their disease. Long-term outcomes are poor. A number of new agents and novel strategies for the treatment of small-cell lung cancer are under evaluation, and this review outlines the current most promising agents and pivotal trials. Oblimersen, an antisense oligonuclide to the oncogene bcl-2, has been safely combined with chemotherapy. The proteosome inhibitor bortezomib has not demonstrated single-agent activity in phase II trials but is now being evaluated with proapoptotic triggers. A number of anti-angiogenic strategies have been evaluated in small-cell lung cancer. The vascular endothelial growth factor (VEGF) antibody bevacizumab and a number of VEGF receptor tyrosine kinase inhibitors are in the early phases of clinical trials. Results from trials have not demonstrated any survival advantage with the addition of matrix metalloproteinase inhibitors. A phase III trial has reported improvements in median survival with the addition of thalidomide to chemotherapy, but toxicity has been problematic. Immunotherapy with p53 vaccines and BEC2 antibodies have shown some promise and require further evaluation to determine whether humoral responses can predict for response. Trials with the immunoconjugate BB-10901 and temirolimus are ongoing.

Abstract
With an increase in the prevalence of patients having multiple medical conditions, along with the increasing number of medical information sources, an intelligent approach is required to integrate the answers to physicians' patient-related questions into clinical practice in the shortest, most specific way possible. Cochrane Scientific Reviews are currently considered to be the "gold standard" for evidence-based medicine (EBM), because of their well-defined systematic approach to assessing the available medical information. In order to develop semantic approaches for enabling the reuse of these Reviews, a system for producing executable knowledge was designed using a natural language processing (NLP) system we developed (BioMedLEE), and semantic processing techniques. Though BioMedLEE was not designed for or trained over the Cochrane Reviews, this study shows that disease, therapy and drug concepts can be extracted and correlated with an overall recall of 80.3%, coding precision of 94.1%, and concept-concept relationship precision of 87.3%.

Abstract
The role of thoracic radiation therapy (RT; TRT) is now established in the management of limited-stage small-cell lung cancer (SCLC). There is increasing evidence in the literature in favor of early concurrent chemoradiation therapy, and a gold standard of care for patients with a good performance status is twice-daily TRT (45 Gy in 3 weeks) with concurrent cisplatin/etoposide. Five-year survival rates > 20% can be expected with this combined-modality approach. Although current clinical trials are exploring the efficacy of new chemotherapeutic strategies for the disease, essential questions related to the optimization of TRT remain unanswered. In particular, the optimal RT dose, fractionation, and treatment volume have not been defined. This review highlights the need for well-designed multinational trials aimed at the optimization and standardization of RT for limited-stage SCLC. These trials should integrate translational research studies to investigate the molecular basis of RT resistance and to develop biomarker profiles of prognosis.

Abstract
BACKGROUND Recent dose-intensity studies of small-cell lung cancer (SCLC) have yielded conflicting results. We carried out a phase III randomized trial in patients with better-prognosis SCLC (i.e., prognostic score of 0-1) to investigate whether doubling the dose density of ifosfamide, carboplatin, and etoposide (ICE) chemotherapy with filgrastim and blood-progenitor-cell support improves survival, compared with standard ICE chemotherapy. METHODS We studied 318 patients with pathologically proven SCLC who were randomly assigned to receive six cycles of ICE chemotherapy with a 4-week (standard arm) or 2-week (dose-dense arm) interval between cycles. Patients in the dose-dense arm received filgrastim subcutaneously daily on days 4 through 14 and had autologous blood collected before cycles 2 through 6, which was returned 24 hours after treatment. Toxicities, including hematologic toxicity and incidence of neutropenic sepsis, were monitored. Survival was calculated by the Kaplan-Meier method. All statistical tests were two-sided. RESULTS The delivered median dose intensity was 99% (interquartile range = 96%-100%) for the standard arm and 182% (interquartile range = 163%-196%) for the dose-dense arm. After a median follow-up of 14 months, overall response to treatment was observed in 118 (80%) of the 148 evaluable patients in the standard arm and in 129 (88%) of the 147 evaluable patients in the dose-dense arm, a statistically non-significant difference. Median overall survival was 13.9 months (95% confidence interval [CI] = 12.9 to 15.8 months) in the standard arm and 14.4 months (95% CI = 12.7 to 16.0) in the dose-dense arm, and the 2-year survival was 22% (95% CI = 16% to 29%) and 19% (95% CI = 14% to 27%), respectively--neither difference being statistically significant. The median treatment free time was 286 days (95% CI = 229 to 343 days) for the standard arm and 367 days (95% CI = 321 to 413 days) for the dose-dense arm (difference = 81 days; P = .109). Statistically significantly more hematologic toxicity was reported in the dose-dense arm than in the standard arm, but the number of cycles complicated by neutropenic sepsis was statistically significantly higher in the standard arm than in the dose-dense arm (15.3% versus 11.6%, respectively; difference = 3.7%, 95% CI = -4.1% to 11.5%; P = .03). CONCLUSIONS Dose-dense ICE chemotherapy for SCLC led to shorter treatment duration and less neutropenic sepsis than did standard ICE but did not improve overall survival.
