The aim of the study was to evaluate efficacy and tolerance of epirubicin and gemcitabine as first-line chemotherapy in patients with advanced non-small-cell lung cancer. A phase I study was performed with the combination of escalating doses of epirubicin intravenously on day 1 and a fixed dose of gemcitabine on days 1 and 8 of a 21 -day cycle. Eighteen patients were included in the phase I part of the study before the maximum tolerated dose was found. Dose-limiting toxicity was febrile neutropenia. The phase II part of the study was continued with epirubicin 100 mg m(-2) on day 1 and gemcitabine 1125 mg m(-2) on days 1 and 8 of a 21-day cycle. Forty-three chemotherapy-naive patients were included. The median age of the patients was 60 years (range 26-75). Most patients (74%) were in stage IV. Granulocytopenia CTC grade 4 occurred in 32.5% and thrombocytopenia grade 4 in 11.6% of cycles. Febrile neutropenia occurred in six patients. Non-haematological toxicity was mainly mucositis CTC grade 2 and 3 in 35% of patients. The tumour response rate was 49% (95% confidence interval (CI) 35-63%). The median survival time for the patients was 42 weeks (95% CI 13-69).

The aim of the study was to evaluate activity, toxicity and health-related quality of life (HRQL) with gemcitabine as second-line treatment after previous chemo- or radiotherapy in non-small-cell lung cancer (NSCLC). Patients with previously treated NSCLC were treated with gemcitabine (1000 mg/m(2)) on days 1, 8 and 15 in a 28-day cycle. Eighty patients were included; median age was 57 years (range 38-77). Prior treatment consisted of platinum-containing chemotherapy in 29 patients and high-dose thoracic radiotherapy in 51 patients. Median number of cycles was three (range 1-6). Granulocytopenia CTC grade 3 and 4 occurred in 9% and thrombocytopenia CTC grade 3 and 4 in 9% of cycles. Non-haematological toxicity was mild. Tumour response was achieved in 13% of the patients (95% CI 7-20), median survival time was 26 weeks and 1-year survival was 22%. Tumour response to second-line gemcitabine could not be predicted from response to first-line therapy, first-line treatment modality or treatment interval. In a subset of 35 patients HRQL was assessed with the European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-LC13 questionnaires and showed improvement or control of symptoms and functioning in approximately 30% of patients. We conclude that gemcitabine in second-line treatment has modest anti-tumour activity, is well tolerated, and may control tumour-related symptoms and improve HRQL in a significant minority of patients.

The Hyogo Ion Beam Medical Center(HIBMC) is a hospital-based charged particle treatment facility. Having two treatment ion beams(proton and carbon) and five treatment rooms, it is a pioneer among particle institutes worldwide. In May 2001, proton therapy was started as a clinical study for patients with localized cancer originating in the head and neck, lung, liver, and prostate. The aim of this study was to investigate the safety, effectiveness, and stability of the treatment units and systems based on the evaluation of acute toxicity, tumor response, and working ratio of the machine, respectively. Six patients, including liver cancer in three, prostate cancer in two, and lung cancer in one, were treated. There was no cessation of therapy owing to machine malfunction. Full courses of proton therapy consisting of 154 portals in all six patients were given exactly as scheduled. None of the patients experienced severe acute reactions of more than grade 3 according to NCI-CTC criteria. Tumor response one month post-treatment was evaluable in five of the six patients, and was CR in 1 (prostate cancer), PR in 2 (lung cancer: 1, liver cancer: 1), and NC in 2(liver cancer: 2). These results indicate that our treatment units and systems are safe and reliable enough for proton irradiation to be used for several malignant tumors localized in the body.

Gemcitabine is usually administered at a planned dose-intensity (DI) from 750 to 800 mg/m2/week. Preclinical data have suggested a possible dose-response relationship of gemcitabine. A multicenter phase II study was conducted to evaluate the activity in terms of no progression rate (complete responses+partial responses+stable diseases) of gemcitabine administered at an increased DI (1000 mg/m2/week) in elderly advanced non-small-cell lung cancer (NSCLC) patients. Secondary endpoints were to evaluate tolerability, progression free survival and overall survival. Elderly (age>or=70 years) chemo-naive advanced NSCLC patients, ECOG PS 0-2, were treated with intravenous gemcitabine 1500 mg/m2 intravenous (30 min infusion) on days 1 and 8 every 21 days for four courses. One hundred and twenty-two patients with a median age of 75 years (range 70-84) entered the study. The following grade 3 (NCI-CTC) haematological toxicities were reported (percent of patients): neutropenia 2.4%, thrombocytopenia 1.6%, anaemia 2.4%. No grades 3-4 non-haematological toxicities were observed. Among 111 evaluable patients 52 (46.8%) no progressions, 17 (15.3%) partial responses (WHO criteria), 35 (31.5%) stable diseases and 59 (53.2%) progressions were observed. Median time to progression was 3.2 months and median duration of survival was 5.4 months. The overall 1-year survival rate was 27%. Although increased dose-intensity of gemcitabine in elderly NSCLC patients is feasible without severe toxicities, this does not seem to be associated with an increased activity and efficacy in comparison to standard gemcitabine regimens with lower dose-intensities.

The aim of this study was to evaluate feasibility and toxicity of escalating doses of epirubicin and paclitaxel plus fixed dose of etoposide and to define the activity of the triplet in extensive disease small-cell lung cancer. Thirteen patients entered the phase I study: the maximum tolerated doses were epirubicin (EpiDX) 90 mg m-2 and paclitaxel (P) 175 mg m-2 with febrile neutropenia as dose-limiting toxicity. The recommended schedule for this regimen for the phase II study was EpiDX 75 mg m-2, P 175 mg m-2, etoposide (E) 100 mg m-2 intravenous (fixed dose) days 1-3 with courses repeated every 21 days. The prophylactic use of colony-stimulating factors (CSFs) was not allowed. Twenty patients entered the phase II trial: median age was 61 years (range 50-70), median Eastern Cooperative Oncology Group performance status 0 (0-2); nine patients had visceral disease and 17 had more than two metastatic sites. A total of 100 courses were administered with a median of 5 (range 1-6) per patients. Main toxicity (NCI-CTC) was myelosuppression: neutropenia grades 3 and 4 in 16 and 35% of the courses, respectively. Seven episodes of febrile neutropenia were documented and one patient required hospital admission. Nonhaematological toxicity was moderate. Seven out of 19 evaluable patients achieved a complete response (37%), nine patients (47.3%) a partial response with an overall response rate of 84.2% (95% confidence interval=60.4-96.6). In this poor prognostic population of patients the triplet epirubicin/paclitaxel/etoposide showed high antitumour activity with mild nonhaematological side effects. The use of CSFs should be able to improve the haematological profile.

EML4-ALK gene fusions have recently been discovered in a subset of human lung carcinomas, and fusions of the ALK tyrosine kinase gene with the NPM, TPM3, CLTC, ATIC, and TFG genes have been found in hematological malignancies. To elucidate the role of fusions between ALK and other genes in pulmonary carcinogenesis, we examined 77 non-small cell lung carcinomas (NSCLCs) for EML4-, NPM-, TPM3-, CLTC-, ATIC-, and TFG-ALK fusion transcripts by RT-PCR and subsequent sequencing analysis. Although no expression of NPM-, TPM3-, CLTC-, ATIC-, or TFG-ALK fusion transcripts were detected in any of the cases, expression of EML4-ALK fusion transcripts was detected in two (2.6%) of the 77 NSCLCs. In one of the two NSCLCs there was fusion between exon 13 of EML4 and exon 20 of ALK, i.e., variant 1, and in the other there was fusion between exon 20 of EML4 and exon 20 of ALK, i.e., variant 2. Both patients had a history of smoking, and histologically the carcinomas were adenocarcinoma. No somatic mutations were detected in the mutation cluster regions of the EGFR, K-RAS, and PIK3CA genes in these two carcinomas, however, a Pro177Ser mutation of the p53 gene was detected in the carcinoma that contained the variant 1 EML4-ALK fusion transcripts. In situ PCR of a paraffin block section showed that the carcinoma with expression of the variant 1 actually contained an EML4-ALK fusion gene. These results suggested that the EML4-ALK fusion gene product is involved in the carcinogenesis of a subset of NSCLCs.

Lung cancer is the leading cause of cancer-related death for both men and women worldwide, and lung cancer also has the highest morbidity and mortality rate among all cancers in China. Chemotherapy (CT) is the most effective and most widely used treatment for lung cancer. Nausea and vomiting are still among the most unpleasant side effects of chemotherapy, especially during highly emetogenic chemotherapy. The standard therapy for preventing chemotherapy-induced nausea and vomiting (CINV) is 5-hydroxytryptamine 3 (5-HT3) receptor antagonists. Palonosetron is a highly potent second-generation selective 5-HT3 receptor antagonist with stronger binding affinity for the 5-HT3 receptor. Palonosetron showed a high antiemetic activity in preclinical study and pivotal trails enrolling patients treated with moderately or high antiemetic activity drugs. Aim of the study was to verify the activity and safety of palonosetron in patients affected by non-small-cell lung carcinoma (NSCLC) and treated with chemotherapy. Patients with stage II-IV NSCLC and receiving chemotherapy entered into the trial. Informed written consent was required. Patients were randomized to received palonosetron or ondasetron. A single pretreatment dose of palonosetron 0.25 mg intravenous followed was administered. Nausea and vomiting were evaluated over 7-day period. Also the adverse effects were reported. Adverse events were evaluated according to the NCI-CTC criteria. Eighty-nine patients were enrolled into the study. The complete responses during the acute phase were 95.4 and 93.3%, respectively. The main side effects were headache 4.5%, constipation 15.7%, anxiety 2.3%. Palonosetron is a very active antiemetic drug for the prevention of nausea and vomiting in NSCLC patients received chemotherapy.

Lung cancer has the highest morbidity and mortality of any malignant tumor. To improve efficacy and reduce toxicity in patients with advanced non-small cell lung cancer (NSCLC), it is important to integrate traditional and conventional medicine. Two hundred and forty patients with advanced NSCLC were randomized to tetrandrine plus GP or GP only. We infused gemcitabine on days 1 and 8; cisplatin on day 1. The tetrandrine group received continuous i.v. infusion for 10 days, with treatment repeated every 21 days. After 2 consecutive treatment cycles, we used RECIST criteria to evaluate short-term efficacy. Quality of life (QOL) was assessed according to Karnofsky score (KPS) and body weight change. We used NCI CTC 3.0 to evaluate treatment toxicity. The short-term objective response rate was 36.1% in the tetrandrine group and 24.3% in the controls (P=0.057). The short-term disease control rate was 63.9% in the tetrandrine group and 52.3% in the controls (P=0.081). The 1-year survival rates were 45.7% and 31.3%, respectively (P=0.059). KPS scores improved by 49.1% and 32.4%, respectively (P=0.012). Body weight increased by 28.7% in the tetrandrine group and 16.2% in the controls (P=0.027). The incidence of grade 2-4 leukopenia, thrombocytopenia, nausea, and vomiting in the tetrandrine group was 38.0%, 19.4%, 46.3%, and 16.7%, respectively; the control group figures were 53.2%, 34.2%, 63.0% and 27.9% (P<0.05). Tetrandrine may improve short-term efficacy and survival in patients with advanced NSCLC. Tetrandrine may also mitigate adverse reactions to chemotherapy and improve QOL for patients with NSCLC.

EpCAM expressing circulating tumor cells, detected by CellSearch, are predictive of short survival in several cancers and may serve as a liquid biopsy to guide therapy. Here we investigate the presence of EpCAM(+) CTC detected by CellSearch and EpCAM(-) CTC discarded by CellSearch, after EpCAM based enrichment. EpCAM(-) CTC were identified by filtration and fluorescent labelling. This approach was validated using different cell lines spiked into blood and evaluated on blood samples of 27 metastatic lung cancer patients. The majority of spiked EpCAM(+) cells could be detected with CellSearch, whereas most spiked cells with EpCAM(low) or EpCAM(-) expression were detected using filtration. Five or more CTC were detected in 15% of the patient samples, this increased to 41% when adding the CTC detected in the discarded blood. The number of patients with CTC and the number of CTC detected were doubled by the presence of EpCAM(-) CTC. In this pilot study, the presence of EpCAM(+) CTC was associated with poor outcome, whereas the EpCAM(-) CTC were not. This observation will need to be confirmed in larger studies and molecular characterization needs to be conducted to elucidate differences between EpCAM(-) and EpCAM(+) CTC.

RTEL1 (regulator of telomere elongation helicase 1; OMIM 608833) gene polymorphisms were linked to lung cancer (LC) susceptibility in a cancer genome-wide association study (GWAS) Here, we assessed whether seven previously reported RTEL1 polymorphisms influenced LC risk in Han Chinese population. All study samples (554 LC cases and 696 cancer-free controls) were collected from the Affiliated Hospital of Xizang Minzu University in China. We assessed associations between SNPs and LC risk using various several genetic models (codominant, dominant, recessive, overdominant, and additive). Whereas rs2738780 showed a protective effect against LC (Odds ratio (OR) = 0.80 ;95% confidence interval (CI): 0.638 = 0.998; p = 0.048), rs7261546(OR = 4.16; 95% CI: 1.35-12.82; p = 0.007), rs6062299(OR=5.08; 95% CI: 1.43-18.10; p = 0.005) and rs3787098(OR = 5.10; 95% CI: 1.43-18.15; p = 0.004) were all associated with increased LC susceptibility (recessive model). Haplotype analysis suggested that ''CTC'' was associated with a 0.8-fold decrease in LC risk (OR = 0.80, 95% CI, 0.63-1.00; Pearson's p = 0.05). These findings suggest a potential association between RTEL1 polymorphisms and LC risk in a Chinese Han population.
