PURPOSE: To investigate the efficacy and toxicity of cisplatin/etoposide (PE) chemotherapy (CHT) with or without accelerated hyperfractionated radiation therapy (ACC HFX RT) and concurrent daily carboplatin/etoposide (CE) in patients with extensive-disease small-cell lung cancer. PATIENTS AND METHODS: A total of 210 patients were treated with three cycles of standard PE. Patients with a complete response (CR) at both the local and distant levels (CR/CR) or a partial response (PR) at the local level and CR at the distant level (PR/CR) received either thoracic ACC HFX RT with 54 Gy in 36 fractions over 18 treatment days in combination with CE followed by two cycles of PE (group 1, n = 55) or an additional four cycles of PE (group 2, n = 54). Patients who experienced less response were treated nonrandomly (groups 3, 4, and 5). All patients with a CR at the distant level received prophylactic cranial irradiation. RESULTS: For 206 assessable patients, the median survival time (MST) was 9 months and the 5-year survival rate was 3.4%. Patients in group 1 had significantly better survival rates than those in group 2 (MST, 17 v 11 months; 5-year survival rate, 9.1% v 3.7%, respectively; P = .041). Local control was also better in group 1, but the difference was only marginally not significant (P = .062). There was no difference in distant metastasis-free survival between groups 1 and 2. Acute high-grade toxicity was higher in group 2 than in group 1. CONCLUSION: The addition of ACC HFX RT to the treatment of the most favorable subset of patients led to improved survival over that obtained with CHT alone.

INTRODUCTION. A number of studies demonstrate the advantage of bilateral mediastinal lymphadenectomy in surgery of non-small cell lung cancer (nSCLC). For surgical approach to the opposite mediastinum for many years there were proposed sternotomy, video-thoracoscopy, and transcervical video-assisted interventions. In our practice, we use videoassisted mediastinal lymphadenectomy (VAMLA).The OBJECTIVE was to learn the efficiency and safety of VAMLA in surgery of NSCLC.METHODS AND MATERIALS. The study included the materials of examination and treatment of 102 patients with NSCLC. 102 patients were divided into 2 groups. In the 1st group (54 patients), VAMLA and lung resection were performed. In the 2nd group (48 patients): anatomical lung resection and systematic ipsilateral lymphadenectomy (SLD) were performed.RESULTS. The average number of remote lymph node stations in group 1 was (7.8±1.7); in group 2 – (4.5±1.2) (p<0.05). The average number of lymph nodes was 26±8.6 compared to (14.3±6) in both groups, respectively (p<0.05). «Occult» pN2-N3 metastasis was detected in 20 % (7/34) of patients of the group 1 and 6.5 % (2/31) of patients of the group 2 (p<0.05). The level of postoperative complications in both groups was 33.4 vs. 29.2 %, respectively (p>0.05). The duration of the postoperative day ((12.7±4.9) vs. (13.7±6.5)) and the duration of pleural drainage ((5.5±4.2) vs. (5.8±4.4)) did not differ in both groups (p>0.05).CONCLUSION. VAMLA is an effective and safe method for evaluating the pN stage of NSCLC. Performing VAMLA in left-sided NSCLC allows removing significantly more lymph nodes and stations in comparison with SLD available in VATS and thoracotomy, which increases the accuracy of postoperative N-staging. The use of the VAMLA in minimally invasive surgery of right-sided NSCLC may be promising in cases of high risk of «occult» pN3 lesion, but requires further study of the role of contralateral lymphatic dissection.

Background: Lung cancer (LCa) is the most frequently diagnosed and lethal cancer worldwide. Histopathological subtyping, which has important therapeutic and prognostic implications, requires material collection through invasive procedures, which might be insufficient to enable definitive diagnosis. Aberrant DNA methylation is an early event in carcinogenesis, detectable in circulating cell-free DNA (ccfDNA). Herein, we aimed to assess methylation of selected genes in ccfDNA from LCa patients and determine its accuracy for tumor subtyping. Methods: Methylation levels of APC, HOXA9, RARβ2, and RASSF1A were assessed in three independent study groups (study group #1: 152 tissue samples; study group #2: 129 plasma samples; study group #3: 28 benign lesions of lung) using quantitative methylation-specific PCR. Associations between gene promoter methylation levels and LCa subtypes were evaluated using non-parametric tests. Receiver operating characteristic (ROC) curve analysis was performed. Results: In study group #2, HOXA9 and RASSF1A displayed higher methylation levels in small-cell lung cancer (SCLC) than in non-small-cell lung cancer (NSCLC). HOXA9 displayed high sensitivity (63.8%), whereas RASSF1A disclosed high specificity (96.2%) for SCLC detection in ccfDNA. Furthermore, HOXA9 methylation levels showed to be higher in squamous cell carcinoma in comparison with adenocarcinoma in study group #1. Conclusions: Methylation level assessments in ccfDNA may provide a minimally invasive procedure for LCa subtyping, complementing standard diagnostic procedures.

7527 Background: Inter-group(IG) study 0096 showed that hyperfractionated and accelerated radiotherapy (HFXART) and concurrent etoposide/cisplatin(EP) improved 5-yr survival (26 %) for patients (pts) with limited small cell lung cancer (LSCLC) compared to daily treatment (TRT) with EP (16%), (p=0.04), HFXART/ EP still had high local failure (LF 40 %) and acute severe esophagitis (ASE) rate (27%). Radiation Therapy Oncology Group (RTOG) 0239 was developed to improve local control (LC) and overall survival (OS) without increasing ASE.Methods: Eligibility included limited stage SCLC, age ≥ 18; P.S. 0–1, with adequate hematologic, hepatic, and renal function. RT was given to large field to 28.8 Gy: 1.8 Gy/ fraction (Fx), 5 days (d) / wk for 16 Fx followed by BID with AP/PA fields in AM @ 1.8 Gy /Fx; boost with 2nd treatment in PM @ 1.8 Gy/Fx on d: 23–26; then off-cord boost, 1.8 Gy, BID, x last 5 days for a total dose of 61.2 Gy in 5 wks. EP was started on day 1 of TRT with P, 60 mg/m2 i.v; E, 120 mg/m2 i.v.; E, 240 mg/m2 p.o. d 2 and 3 or E 120 mg/m2 i.v. / d on d 2 or 3. Repeat cycle every 3 wks x 2 cycles with RT, followed by adjuvant EP alone x 2 cycles. CR pts were asked to participate in the prophylactic cranial irradiation (PCI) study RTOG 0212. RTOG 0239 was designed to detect an improvement in the 2-year survival rate from 47% to 60% with less than 30% of ASE.Results: RTOG 0239 accrued 72 pts (71 eligible) from June 20, 2003 to May 23, 2006. The median follow-up time is 19.0 months for all pts, and 30.4 months for pts still alive. The median age was 63, 52% female, 58% Zubrod PS 0. The 2 -year survival rate was 37 % [95% CI: 25.6, 47.7]. 13 pts (18 %) experienced severe esophagitis. 2 treatment related deaths (2.8%) were reported. Response rates 2 months post RX showed CR 41%, PR 39%, SD 10% and PD 6%. Locoregional control rate at two years was 80%. RT compliance was 95 %.Conclusions: RTOG 0239, AHTRT/EP for LSCLC resulted in 37% 2-year OS, 80% 2 year LC and 18% ASE. Compliance with treatment was high and treatment-related death rate was similar to other chemoradiation regimens. Although 2-year OS did not achieve 60%, excellent LC and low ASE were achieved by RTOG 0239 which became one of 3 arms in an ongoing randomized trial of LSCLC RTOG0538/CALGB30610. [Table: see text]

BackgroundWBRT and systemic chemotherapy are the mainstay treatments for small-cell lung cancer (SCLC) brain metastases (BM). However, current recommendations are mainly based on evidence from retrospective analyses. A recent randomized trial found no benefits from WBRT compared with best supportive care (BSC) in patients with more than three BM from non-small-cell lung cancer (NSCLC). Herein, we aimed to evaluate the roles of WBRT and chemotherapy further in the management of BM from SCLC.Materials and MethodsThere were 698 patients with BM from SCLC included. Of these, 580 received anti cancer treatment (Group 1), including 178 who received WBRT only (Group 1a), 129 who received chemotherapy only (Group 1b), and 273 who received WBRT plus chemotherapy (Group 1c). The other 118 received BSC (Group 2). Propensity score matching (PSM) analysis was used to compare Group 2 with each of the other groups.ResultsAfter PSM, compared with Group 2 (n = 118), patients in Group 1 (n = 440) had a prolonged overall survival (OS) in both univariate and multivariate tests, with a median survival time of 10 months (95% CI = 9−11) in Group 1 and 3.5 months (95% CI = 2−7) in Group 2 (p &lt; 0.001). In subgroup analyses, patients who received WBRT plus chemotherapy were more likely to benefit from treatment (p &lt; 0.001). Chemotherapy alone or WBRT alone did not show survival benefits.ConclusionWBRT plus chemotherapy improved OS in patients with BM from SCLC as compared to BSC. Chemotherapy alone and WBRT alone did not show survival benefits. This retrospective study suggests that SCLC patients with BM who receive WBRT combined with chemotherapy have a better outcome than those receiving BSC alone.

Background The primary aim of the study was to compare two different dose levels of megestrol acetate, administered for cancer-related anorexia and cachexia for 3 months. Methods From August 1996 to December 2000, 119 patients with advanced non-small cell lung cancer were randomized to take 160 mg/day or 320 mg/day of megestrol acetate for 3 months at the Gülhane Military Medicine Academy of Ankara, Turkey. Patients were controlled at biweekly periods. Results There were 59 patients in the single dose arm (group 1) and 60 patients in the twice a day dose arm (group 2). The mean percentages of weight loss were 16.9% and 16.7% in group 1 and 2, respectively. In the first and the second month of weight gain, there were no significant differences in the two groups (P = 0.23 and P = 0.11). In the third month, weight gain was significantly higher in group 2 than in group 1 (P = 0.038). Toxicity was similar for both dose levels. Conclusions Megestrol acetate can be safely and effectively given to patients with advanced non-small cell lung cancer. Although lower doses of megestrol acetate can be effective for anorexia and cachexia, the higher dose level seems to be more efficient.

Background. This study tested the hypothesis that circulating microparticles (MPs) are useful biomarkers for predicting one-year mortality in patients with end-stage non-small cell lung cancer (ES-NSCLC).Methods and Results. One hundred seven patients were prospectively enrolled into the study between April 2011 and February 2012, and each patient received regular follow-up after enrollment. Levels of four MPs in circulation, (1) platelet-derived activated MPs (PDAc-MPs), (2) platelet-derived apoptotic MPs (PDAp-MPs), (3) endothelial-derived activated MPs (EDAc-MPs), and (4) endothelial-derived apoptotic MPs (EDAp-MPs), were measured just after the patient was enrolled into the study using flow cytometry. Patients who survived for more than one year were categorized into group 1(n=56)(one-year survivors) and patients who survived less than one year were categorized into group 2(n=51)(one-year nonsurvivors). Male gender, incidence of liver metastasis, progression of disease after first-line treatment, poor performance status, and the Charlson comorbidity index were significantly higher in group 2 than in group 1 (allP<0.05). Additionally, as measured by flow cytometry, only the circulating level of EDAc-MPs was found to be significantly higher in group 2 than in group 1(P=0.006). Multivariate analysis demonstrated that circulating level of EDAc-MPs along with brain metastasis and male gender significantly and independently predictive of one-year mortality (allP<0.035).Conclusion. Circulating EDAc-MPs may be a useful biomarker predictive of one-year morality in ES-NSCLC patients.
