Abstract
The tyrosine kinase c-Src is upregulated in various human cancers, but the molecular mechanisms underlying c-Src-mediated tumor growth remain unclear. Here we examined the involvement of microRNAs in the c-Src-mediated tumor growth. Microarray profiling revealed that c-Src activation downregulates a limited set of microRNAs, including miR-99a, which targets oncogenic mammalian target of rapamycin (mTOR) and fibroblast growth factor receptor 3 (FGFR3). Re-expression of miR-99a suppressed tumor growth of c-Src-transformed cells, and this effect was restored by the overexpression of mTOR. The downregulation of miR-99a was also observed in epidermal growth factor- and Ras-transformed cells, and it was suppressed by inhibiting the mitogen-activated protein kinase (MAPK) pathway. Furthermore, miR-99a downregulation is associated with mTOR/FGFR3 upregulation in various human lung cancer cells/tissues. The tumorigenicity of these cells was suppressed by the introduction of miR-99a. These findings suggest that the miR-99a-mTOR/FGFR3 pathway is crucial for controlling tumor growth in a wide range of human cancers that harbor upregulation of the Src-related oncogenic pathways.

Abstract
103 Background: We evaluated the potential of progression-free survival (PFS) and time to progression (TTP) to act as surrogates of overall survival (OS) in clinical trial settings by a comprehensive literature-based analysis. Methods: Randomized trials of systemic chemotherapy for advanced gastric cancer were identified by comprehensive electronic and manual search. Correlations between PFS/TTP and OS were evaluated. Results: Thirty-six trials with a total of 83 treatment arms and 10,484 patients were selected for analysis. The nonparametric Spearman rank correlation coefficient (p) between median PFS/TTP and OS was 0.70 (95% CI, 0.59 to 0.82) and the correlation coefficient between hazard ratios in PFS/TTP and OS was 0.80 (95% CI, 0.68 to 0.92). Correlation tended to be higher in non-Asian (p = 0.80; 0.61-0.98) than Asian trials (p = 0.67; 0.39-0.94), higher in trials reporting PFS (p = 0.85; 0.72-0.97) than in those reporting TTP (p = 0.60; 0.24-0.97), and higher in trials in patients with measurable lesions only (p = 0.91; 0.77-1.00) than in those including non-measurable lesions (p = 0.71; 0.50-0.93), albeit that none of these differences was significant. Conclusions: Our results indicate that improvements in PFS/TTP in advanced gastric cancer strongly correlate with improvements in OS. PFS/TTP may be an appropriate surrogate for OS in clinical trials for advanced gastric cancer. No significant financial relationships to disclose.

Abstract
OBJECTIVE Previous studies have reported that serum IL-18 levels are increased in some cancers. We investigated whether IL-18 production is increased in sera and cancer cells of patients with non-small cell lung cancer (NSCLC). PATIENTS OR MATERIALS Serum levels of IFN-gamma and IL-18 and thioredoxin 1 (TRX1) were measured in 79 patients (51 males, 28 females, median age 67 years) with advanced NSCLC (57 adenocarcinoma, 22 squamous cell carcinoma; TNM stages IIIA [n=11], IIIB [n=24], and IV [n=44]) and 75 healthy age-matched controls (44 males, 31 females, median age 65 years) by enzyme-linked immunosorbent assay. We examined IL-18 production in the lungs and sites of bone metastasis of adenocarcinoma by immunohistochemistry. RESULTS Serum IL-18, IFN-gamma, and TRX1 levels in NSCLC patients were significantly (p<0.0001, p=0.0031, and p<0.0001, respectively) higher than in control subjects, while serum IFN-gamma levels in NSCLC were slightly increased. Serum IL-18, but not IFN-gamma or TRX1, levels were significantly (p=0.0102) and negatively associated with overall survival in NSCLC. The serum IL-18 level was identified as an independent prognostic factor for overall survival in multivariate survival analysis. Moreover, serum IL-18 levels were significantly (p=0.049) higher in NSCLC with bone metastasis than in NSCLC without bone metastasis. Based on immunohistochemistry, we observed that cancer cells in the lungs and bone metastases markedly produced IL-18. CONCLUSION Our results suggest that elevated serum IL-18 levels may be associated with IL-18 producing cancer cells in advanced NSCLC.

Abstract
The combination of carboplatin and paclitaxel is the most commonly used regimen for the treatment of advanced non-small cell lung cancer (NSCLC) patients. The expression of excision repair cross-complementation group 1 (ERCC1) is reported to be correlated with resistance to platinum-based drugs. Class III beta-tubulin is reported to be correlated with resistance to taxanes. We evaluated whether ERCC1 and class III beta-tubulin expression could predict progression-free and/or overall survival in relapsed NSCLC patients treated with carboplatin and paclitaxel. Immunohistochemistry was used to examine the expression of these two proteins in resected lung tumor samples obtained from 45 patients treated with carboplatin and paclitaxel against recurrent tumors after curative resection. Immunostaining for ERCC1 and class III beta-tubulin was positive in 20 and 16 patients, respectively. Patients negative for ERCC1 had a significantly longer median progression-free (44 weeks vs. 28 weeks, P=0.046) and overall (102 weeks vs. 56 weeks, P=0.010) survival than those positive for ERCC1. Patients negative for class III beta-tubulin expression had a significantly longer median progression-free (40 weeks vs. 35 weeks, P=0.031), but not overall (78 weeks vs. 57 weeks, P=0.087), survival than those positive for class III beta-tubulin expression. In particular, patients negative for both ERCC1 and class III beta-tubulin had significantly longer progression-free (P=0.036) and overall survival (P=0.015), compared with those positive for ERCC1 and/or class III beta-tubulin. In multivariate analysis, negative class III beta-tubulin expression (hazard ratio=1.912, P=0.048) was significantly favorable factor for progression-free survival, and negative ERCC1 expression (hazard ratio=2.580, P=0.014) and better performance status (hazard ratio=3.287, P=0.007) were significantly favorable factors for overall survival. This retrospective study indicates that immunostaining for ERCC1 and class III beta-tubulin may be useful for predicting survival in NSCLC patients receiving carboplatin and paclitaxel against recurrent tumors after curative resection and can provide information critical for planning personalized chemotherapy.

Abstract
Expression of excision repair cross-complementation group 1 (ERCC1), p53, or thioredoxin (TRX) is reported to be correlated with resistance to platinum-based drugs. The authors evaluated whether ERCC1, p53, or TRX expression could predict progression-free and/or overall survival in relapsed non-small cell lung cancer (NSCLC) patients treated with platinum-based chemotherapy. Immunohistochemistry was used to examine the expression of these three proteins in resected lung tumor samples obtained from 67 patients treated with platinum-based chemotherapy against recurrent tumors after curative resection. Immunostaining for ERCC1, p53, and TRX was positive in 29, 35, and 24 patients, respectively. Patients negative for ERCC1 had a significantly longer median progression-free (44 vs 26 weeks, P = 0.0075) and overall (73 vs 44 weeks, P = 0.0006) survival than those positive for ERCC1. Patients negative for p53 expression had a significantly longer median overall (70 vs 62 weeks, P = 0.0289), but not progression-free (37.5 vs 36 weeks, P = 0.2465), survival than those positive for p53 expression. From multivariate analysis, negative ERCC1 expression (hazard ratio [HR] = 1.3740, P = 0.0147) was a significantly favorable factor for progression-free survival, and negative ERCC1 expression (HR = 1.6533, P = 0.0018) and better performance status (HR = 1.9117, P = 0.0017) were significantly favorable factors for overall survival. This retrospective study indicates that immunostaining for ERCC1 may be useful for predicting survival in NSCLC patients receiving platinum-based chemotherapy against recurrent tumors after curative resection and can provide critical information for planning personalized chemotherapy.

Abstract
OBJECTIVE A single-center phase I trial was designed to determine both the dose-limiting toxicities and the maximum tolerated dose (MTD) for amrubicin hydrochloride in combination therapy with cisplatin for advanced non-small cell lung cancer (NSCLC) patients with prior chemotherapy. METHODS Eligible patients received amrubicin and cisplatin on days 1 through 3 every 3 or 4 weeks. Cisplatin was administered at a fixed dosage of 20 mg/m(2) while the administered dose of amrubicin was started at 20 mg/m(2). Each group comprised 3 or 6 patients. When dose limiting toxicities were noted in three or more of six patients at a particular level, that level was estimated to be the MTD. RESULTS Fifteen patients were enrolled in this study, including 5 males and 10 females, with a median age of 57. The dose limiting toxicities included grade 4 neutropenia which lasted 4 or more days and febrile neutropenia. The non-hematologic toxicities were well managed and rarely severe. The MTD of amrubicin in this combination regimen was estimated to be 30 mg/m(2).A partial response was observed in 4 of 15 patients (27%). CONCLUSIONS The recommended dose was thus determined to be 25 mg/m(2) amrubicin with 20 mg/m(2) cisplatin for 3 consecutive days. A phase II study is currently underway.

Abstract
OBJECTIVE To examine predictive values for the effect of the "Type 1" (hopeless and emotion-suppressive, cancer prone), "Type 4" (autonomous, healthy), and "Type 5" (rational/antiemotional, cancer prone) personalities proposed by Grossarth-Maticek on the prognosis of lung cancer patients. METHODS 68 lung cancer patients were scored on the Types 1, 4, and 5 personality scales of the Short Interpersonal Reactions Inventory and were followed until the date of death or were censored at a maximum of 5.7 years after entry. RESULTS The stage at diagnosis tended to be higher in patients with a high Type 1 or a low Type 4 score. A univariate Cox proportional hazards model showed that a high tendency toward Type 1 or Type 5 was related to an increased hazard of death. Adjustment for age, performance status, and stage, however, attenuated the relation to Type 1, leaving only Type 5 as a significantly related personality factor. CONCLUSION A high Type 5 tendency may predict poor survival in lung cancer patients, whereas Types 1 and 4 may not be independent predictors.

Abstract
Gefitinib is an inhibitor of epidermal growth factor receptor tyrosine kinase, which has a tumour reducing effect in non-small cell lung cancer (NSCLC). In this study, we retrospectively reviewed the clinical data from 105 patients with advanced NSCLC treated with gefitinib at our department between May 2002 and April 2004. The overall response rate was 27.8% and the median survival time was 9.3 months. Pretreatment characteristics suggested that those with no history of smoking or an elevated serum carcinoembryonic antigen (CEA) level were more likely to be sensitive to gefitinib (P = 0.009). A multivariate analysis indicated good PS (P < 0.0001) and elevated serum CEA level (P = 0.0027) to be independent prognostic factors. These data show that the serum CEA level can be a predictive factor for the efficacy of gefitinib treatment while it is also a prognostic factor for advanced NSCLC patients undergoing this treatment.

Abstract
BACKGROUND The incidence of malignant pleural mesothelioma (MPM) is expected to increase due to delayed control of occupational exposure to asbestos in Japan. We investigated the use of triplet combination chemotherapy with cisplatin (CDDP), gemcitabine (GEM) and vinorelbine (VNR) for the treatment of Japanese patients with MPM. METHODS From December 2000 to August 2003, 12 patients received the following regimen: CDDP 40 mg/m(2), GEM 800 mg/m(2) and VNR 20 mg/m(2) on days 1 and 8 every 4 weeks. Among the 12 patients, six selected patients underwent an extrapleural pneumonectomy (EP) after a median of three cycles of triplet chemotherapy. RESULTS The overall response rate for all patients and the response rate for chemotherapy-naive cases were 58 and 67%, respectively. The median survival time and survival rate at 2 years for all patients were 11 months and 50%, respectively. The 2-year survival rates for the patients with and without EP were 83.3 and 16.7%, respectively. CONCLUSIONS Triplet chemotherapy with CDDP, GEM and VNR was thus found to be highly effective for patients with MPM and its toxicity was manageable. A multi-institutional phase II trial is now being planned to establish the effectiveness of this new regimen in chemotherapy-naive patients with MPM.

Abstract
BACKGROUND Pulmonary giant cell carcinoma is one of the rare histological subtypes with pleomorphic, sarcomatoid or sarcomatous elements. The prognosis of patients with this tumor tends to be poor, because surgery, irradiation and chemotherapy are not usually effective. CASE PRESENTATION We herein report a patient with pulmonary giant cell carcinoma with stage IV disease in whom aggressive multi-modality therapy resulted in a long-term survival. A 51-year-old male underwent an emergent operation with a partial resection of small intestinal metastases due to bleeding from the tumor. The patient also underwent a left pneumonectomy due to hemothorax as a result of the rapid growth of the primary tumor. Thereafter, two different regimens of chemotherapy and a partial resection for other site of small intestinal metastases and a splenectomy for splenic metastases were performed. The patient is presently doing well without any evidence of recurrence for 3 years after the initial operation. CONCLUSION This is a first report of a rare case with stage IV pulmonary giant cell carcinoma who has survived long-term after undergoing aggressive surgical treatment and chemotherapy.

Abstract
BACKGROUND AND OBJECTIVES To determine the prognostic factors for long-term survivors (LTS) with stage IV non-small cell lung cancer (NSCLC) who had undergone various treatments. PATIENTS AND METHODS From 1990 to 1999, 222 NSCLC patients with stage IV disease, who had been treated in our department, were reviewed. As the initial treatment, 135 patients (48%) were treated with chemotherapy alone, 52 patients with a combination of chemotherapy and radiotherapy, 19 patients underwent an operation with or without any other therapeutic modalities and 16 were received radiotherapy alone. RESULTS Seventeen (7.7%) patients survived for more than 2 years, and all but one had adenocarcinoma. Among these LTS, eight patients received surgery as the initial therapy, and 16 (94.1%) received some type of local-control therapy, including surgery or radiotherapy, during the course of their disease. Regarding the clinical characteristics between LTS and others (non-LTS), an early N status, a single metastatic site, a good performance status, and surgery for initial therapy were all found to be significantly important factors for LTS. A multivariate analysis using a logistic regression model also showed an early N status and surgical treatment to be significantly associated with LTS. CONCLUSIONS Selected patients with an early N status may be appropriate candidates for aggressive multimodality treatment including surgery, in order to provide a long-term survival for stage IV NSCLC.

Abstract
BACKGROUND The exclusion of brain metastasis is important to determine the optimal treatment plan in patients with non-small cell lung cancer (NSCLC). However, a routine examination using magnetic resonance imaging (MRI) for the brain remains controversial in preoperative patients with resectable disease. METHODS To assess the necessity of routine brain MRI for preoperative patients, a retrospective analysis for a consecutive series of 338 patients with NSCLC was performed. Among the 338 patients, 141 patients who were considered to have potentially resectable diseases through an examination of the chest plus an upper abdominal computed tomography scan and bone radioisotope scan with no neurological symptoms received MRI for examination of brain metastasis. RESULTS The incidence of brain metastasis detected by MRI was 2.1% (three of 141) in all patients, 0% (zero of 80) in patients with N0 disease, 5.2% (one of 19) in N1, and 4.7% (two of 42) in N2 cases. CONCLUSION In patients with resectable NSCLC, a brain MRI is not considered to be useful due to the low incidence of asymptomatic brain metastasis.

Abstract
OBJECTIVE Visceral pleural invasion caused by non-small cell lung cancer is a factor in the poor prognosis of patients with that disease. We investigated the relationship between the diagnosis of visceral pleural invasion by using a jet stream of saline solution, which was previously reported as a new cytologic method to more accurately detect the presence of visceral pleural invasion, and prognosis. METHODS From January 1992 through December 1998, 143 consecutive patients with peripheral non-small cell lung cancer that appeared to reach the visceral pleura underwent a surgical resection at the Department of Thoracic Oncology, National Kyushu Cancer Center. The surface of the visceral pleura in patients undergoing lung cancer resection was irrigated with a jet stream of saline solution. The diagnosis of visceral pleural invasion was determined by means of either a pathologic examination or by means of a jet stream of saline solution. In addition, a cytologic examination of the pleural lavage fluid obtained immediately after a thoracotomy was evaluated. RESULTS Forty-nine (34%) resected tumors were identified as having visceral pleural invasion. The diagnosis of visceral pleural invasion in 31, 6, and 12 patients was determined by using a jet stream of saline solution alone, pathologic examination alone, or both, respectively. The visceral pleural invasion and positive findings of intrapleural lavage cytology were linked. Although there was no significant difference between the incidence of distant metastases in the patients with visceral pleural invasion and those without visceral pleural invasion, the incidence of local recurrence, especially regarding carcinomatous pleuritis (malignant pleural effusion, pleural dissemination, or both), in the patients with visceral pleural invasion was significantly higher than in those without visceral pleural invasion. The recurrence-free survival of patients with visceral pleural invasion was significantly shorter than that of patients without visceral pleural invasion (P =.004), even patients with stage I disease (P =.02). There was also a significant difference between the patients with or without visceral pleural invasion in the overall survival (P =.02). Visceral pleural invasion was independently associated with a poor recurrence-free survival on the basis of multivariate analyses (P =.03), as were sex (P =.03), age (P = 002), and the stage of the disease (P <.0001). CONCLUSIONS This study confirmed that the jet stream of saline solution method in addition to ordinary pathologic examination was useful for detecting visceral pleural invasion, which is considered to be one of the causes of local recurrence, especially in carcinomatous pleuritis.

Abstract
BACKGROUND AND OBJECTIVES Surgery is a standard treatment in patients with clinical stage IB/II non-small cell lung cancer (NSCLC). We often have difficulty in treating of elderly patients due to their insufficient physiological function. To better manage such elderly patients, the clinical characteristics and prognosis of patients with these stages, who were 75 years of age or older, were reviewed. METHODS From 1972 to 1999, 112 elderly patients with these stages were treated in our department. These patients comprised 88 men and 24 women. The histological types were 50 adenocarcinomas, 51 squamous cell carcinomas, 8 large cell carcinomas, and 3 adenosquamous carcinomas. RESULTS Seventy-four patients (66%) underwent a surgical resection, including 60 surgery alone, 14 combined modality therapy. Radiotherapy, with or without chemotherapy, was given to 30 patients (27%), and chemotherapy alone to 5 (4.5%). In addition, 3 (2.7%) were given no therapy. The survivals of the surgery group at 2 and 5 years are 53% and 21% and those of the radiotherapy group are 35% and 3%, respectively. A multivariate analysis in radiotherapy group shows the predominant prognostic factor to be adenocarcinoma. The 2-year survival of the radiotherapy group in patients with adenocarcinoma is 58%, while that of patients with squamous cell carcinoma is 22%. CONCLUSIONS These above observations suggest that radiotherapy is an alternative strategy for patients who cannot undergo surgery, especially with adenocarcinoma.

Abstract
BACKGROUND Combination chemotherapy using an oral combination of uracil and tegafur (UFT) plus cisplatin and concurrent thoracic radiotherapy is reported to have a high response rate and less toxicity for locally advanced non-small-cell lung cancer (NSCLC) patients. We performed a phase II trial using this chemoradiotherapy as an induction treatment. METHODS Patients with marginally resectable stage IIIB NSCLC, an age younger than 70 years, a performance status of 0 or 1, and good organ function were eligible. The UFT (400 mg/m(2)) was administered orally on days 1 through 14 and 22 through 35 and cisplatin (80 mg/m(2)) was injected intravenously on days 8 and 29. Radiotherapy with a total dose of 40 Gy was delivered in 20 fractions from day 1. A surgical resection was performed from 3 to 6 weeks after completing the induction treatment. RESULTS Twenty-seven patients, 18 male and 9 female with a median age of 56 years and ranging from 36 to 69 years, were entered into the phase II trial. Clinical T4 and N3 cancers were observed in 22 and 7 patients, respectively. Twenty-five (93%) achieved a partial response. The most frequently observed adverse event was grade 3 leukopenia in 26%. Of 25 patients who underwent a thoracotomy, 22 had a tumor resection. In all 22 patients a complex resection including a resection of the superior vena cava, carina, and vertebrae was required. Operative morbidity and mortality rates were 36% and 4% respectively. The calculated 1-year and 3-year survival rates of all 27 patients were 73% and 56% respectively. CONCLUSIONS Chemotherapy using UFT plus cisplatin and concurrent radiotherapy as induction treatment and a surgical resection for patients with marginally resectable stage IIIB NSCLC is feasible and promising. However it is difficult to conduct multi-institutional trials even for selected stage IIIB disease as a complex resection in almost all patients is necessary.

Abstract
We report the case of a 58-year-old man who underwent complete resection for locally advanced non-small-cell lung cancer (cT4N2M0). The patient received UFT (400 mg/m2 orally on days 1-14 and 22-35) and cisplatin (80 mg/m2 intravenously on days 8, 29) with a total 40 Gy, delivered in 20 fractions on days 1-26. The tumor reduction rate was 76%, and no remarkable toxicities were observed. The patient underwent complete resection and a pathologic complete response was observed. This induction concurrent chemoradiotherapy (followed by surgery) is considered to be effective and safe.
