Abstract
The anatomy of the lateral ulnar collateral ligament (LUCL) of the elbow was investigated in 26 fresh frozen cadavers. Two types of insertion of the LUCL were originally described but we found another type which is characterized by a broad single expansion along with a thin membranous fibre. Strain on the LUCL was measured in situ during extension and flexion with the forearm in supination, pronation and neutral. Strain in the proximal fibres started to occur at around 32° flexion and peaked at between 50° and 60° flexion. Strains measured in the distal fibres were smaller in magnitude. Forearm rotation had little effect on strain during extension to flexion. Based on these results, we conclude that the LUCL functions in unison with the annular ligament.

Abstract
BACKGROUND Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) has a high diagnostic value in sarcoidosis if the obtained histological specimen is indicative of a non-caseating epithelioid-cell granuloma. However, EBUS-TBNA in sacoidosis sometimes affords solely cytological specimens. OBJECTIVE To investigate the relevance of EBUS-TBNA cytology specimens in diagnosing sarcoidosis. DESIGN The study population comprised 72 patients with sarcoidosis and 116 patients who had thoracic malignancies and intrathoracic lymphadenopathy but were eventually proven to be metastasis-free (controls). The EBUS-TBNA samples obtained for these subjects were blindly evaluated for the presence of epithelioid cell clusters by 2 independent cytoscreeners and a pathologist. RESULTS Interobserver variability in the specimen grading was minimal. The sensitivity and specificity were 65.3% and 94.0%, respectively. The sensitivity was high, at 87.5%, for the combined cytological and histological examinations. Of 7 controls whose cytological specimens showed epithelioid cell clusters, 3 were also deemed positive for sarcoidosis on histological examination, which indicated that they had sarcoid reaction to cancer. CONCLUSIONS Cytological evaluation of the EBUS-TBNA specimens had higher sensitivity than histological evaluation alone for intrathoracic lymphadenopathy due to sarcoidosis. It should be recognized, however, that up to 6% of patients with thoracic malignancy may have sarcoid reaction in non-metastatic lymph nodes.

Abstract
PURPOSE Despite recent improvements in supportive care, treatment-related death (TRD) remains a serious problem for lung cancer patients undergoing systemic chemotherapy. However, few studies have formally assessed possible changes in the TRD rate over the past two decades. PATIENTS AND METHODS We searched phase III trials to address the role of systemic treatment of advanced non-small-cell lung cancer (NSCLC). Time trend was assessed using linear regression analysis. RESULTS The overall incidence of TRD was calculated from 119 trials including 263 chemotherapy arms (46 477 patients), with information about the causes of deaths available for 197 arms (75%, 30 147 patients). Cisplatin-based regimens were the most frequently investigated. The crude TRD rate in the overall cohort of 119 trials was 1.26% and has been notably consistent over the investigated time (P = 0.762). The most common cause of death was febrile neutropenia, with no significant change in its incidence over the years (P = 0.139). In contrast, deaths due to renal toxicity decreased significantly (P = 0.042), whereas deaths due to pulmonary disorder increased significantly (P = 0.007). Among the pharmacological agents investigated, docetaxel (Taxotere) and epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) were associated with relatively high rates of deaths from pulmonary disorders, but EGFR-TKIs were not associated with death from any other cause. CONCLUSIONS Despite of potential confounders in our results, the overall TRD rate has remained low, but not negligible, in phase III trials for advanced NSCLC, over the past two decades. Notably, the incidence and pattern of TRD stratified by cause have changed considerably.

Abstract
e19056 Background: Erlotinib was approved in Dec 2007 in Japan, and incidence and pattern of ILD during its therapy for Japanese pts with NSCLC has not still been determined, although we had previously reported the frequency of ILD through the gefitinib treatment [PASCO2004, #7063]. In this study, we intended to elucidate this issue in pts receiving erlotinib therapy. Methods: We reviewed the clinical records of 159 pts who had initiated erlotinib therapy last year (cohort A), and of 330 pts receiving gefitinib between 2000 and 2003 (cohort B) for comparing the incidence and pattern of ILD during the both TKI treatments. Toxicity data during the first months after the initiation of TKIs were obtained. Results: The demographics of 489 pts were as follows; M:63%, Ad:75%, and PS 0–1:69%. None of pts in the cohort B received erlotinib therapy before the gefitinib treatment, whereas 66 of the 159 cohort A pts (42%) were given gefitinib before the erlotinib therapy. In 23% and 28% of the pts in the cohorts A and B, erlotinib and gefitinb treatments were discontinued within 1 month after the initiation of TKI therapy, respectively. Two pts (1.3%) developed ILD in the cohort A during the first month of erlotinib treatment, while 8 ILD-events (2.4%) were observed in the gefitinib therapy (cohort B) during the same treatment period. Both 2 pts who developed ILD during the erlotinib therapy had not had a history of prior gefitinib treatment. The toxicity grades of ILD were as follows: grades 1 and 2 in 1 each (cohort A) and grades 3, 4 and 5 in 1, 1 and 6 pts, respectively (cohort B). Statistically significant factors affecting the occurrence of ILD by multivariate analysis were presence of prior pulmonary fibrosis (OR=37.3, p<0.01) and poor PS (OR=6.4, p=0.02), but type of TKIs was not a significant risk factor for ILD. Conclusions: In this setting, the type of TKIs did not affect the incidence of ILD although its incidence after the initiation of erlotinib was somewhat low as compared with that during gefitinib therapy. In addition, the grade of ILD was less severe in the cohort A. These might be partly due to a patient selection based on the recent awareness of Japanese physicians regarding the risk factors for ILD events who learned it through the gefitinib treatment. No significant financial relationships to disclose.

Abstract
8067 Background: Efficacy of gefitinib therapy strongly depends on the presence of active EGFR mutations in Asian NSCLC pts, with objective response rates (ORR) of 71.2% and only 1.1% in active mutant-positive (EGFRmt+) and -negative (EGFRmt-) tumors, respectively [Mok T, ESMO2008]. Recently, the survival advantage of erlotinib, another TKI, is observed even in pts with EGFRmt- tumors (HR=0.74, p=0.09 [Zhu C, JCO2008]), indicating such subpopulation might also benefit from this TKI. The aim of this trial was to evaluate its efficacy and toxicity in Japanese pts with relapsedEGFRmt- tumors. Methods: Primary endpoint was ORR. Patients with EGFRmt--NSCLC previously treated with one to three chemotherapy regimens were enrolled in this trial. The mutation status was assessed by the PCR clamp methods. Erlotinib was administered at a dose of 150mg/day until disease progression or unacceptable toxicities. Results: Thirty pts were enrolled between Jan and Dec 2008. Median duration of erlotinib treatment was 60 days. All pts were assessable for efficacy and safety. Demographics of the pts were as follows: M/F:24/6, Ad/others:20/10, ECOG-PS 0/1/2:7/19/4, and smoker/non-smoker:22/8. Platinum-based regimens were commonly used as the prior chemotherapy. Objective response was obtained in one pt (3.3%; RECIST). Seventeen pts obtained SD (56.7%). Toxicity profiles were almost tolerable with the treatment interruption in 11 pts (median duration; 10 days). Skin rash was common (grades 1, 2 and 3 in 7, 15, and 7 pts, respectively; NCI-CTCAE ver3). One pt developed grade 4 pulmonary embolism, but it seemed due to disease progression. Other 2 pts developed interstitial lung disease (grades 2 and 3 in one pt each). No treatment-related deaths (TRD) occurred. With a median follow-up time of 6.4 months, MST and MPFS time were 8.6 and 2.1 months, respectively. Conclusions: This is a first prospective biomarker study showing that erlotinib therapy for pretreated pts with EGFRmt- tumors seems as almost effective and safe as the standard docetaxel therapy (PR: 5.8%, SD: 42.7%, MST: 7.0 months, MTTP: 2.5 months and TRD: 4.9% [Shepherd JCO2000]).

Abstract
8058 Background: Recent studies have demonstrated that docetaxel (DOC) monotherapy provides a significant survival prolongation in relapsed pts with NSCLC. However, its benefit remains modest and further improvement is needed. S-1 is a newly developed oral 5-fluorouracil derivative, possessing a promising anti-tumor activity in NSCLC. Based on a superior effect of combination of DOC and 5-fluorouracil derivative (capecitabine) to DOC alone in anthracycline-pretreated breast cancer pts, we conducted a randomized phase II study to evaluate the clinical significance of adding S-1 to DOC in the second-line setting. Methods: Pts with relapsed NSCLC to the first-line platinum-based chemotherapy were randomly allocated to DOC monotherapy (A arm; 60 mg/m2, day 1, q 3 wks) or a combination chemotherapy (B arm) of DOC (40 mg/m2, day 1, q 3 wks) and S-1 (80 mg/m2, days 1 to 15). The doses of arm B were determined based on the results of a phase I study conducted for Japanese pts with gastric cancer (Anticancer Res 24: 1843, 2004). The primary endpoint was response rate and secondary endpoints included OS, PFS and toxicity. Results: Between 2005 and 2008, 60 pts were enrolled (A/B: 29/31 pts). Demographics of the pts were as follows: M/F: 49/11, Ad/others: 40/20, ECOG-PS 0/1: 38/22. A median number of courses administered was 4 (range: 1 to 6). Objective response was obtained in 6 (20.7%) and 5 pts (16.1%) in arms A and B, respectively. With a median follow-up time of 16.9 months, MST and median PFST in arm A were longer than arm B (22.9 vs. 8.7 months and 3.7 vs. 3.4 months, respectively). The major toxicity was myelosuppression, with grade 4 neutropenia of 62% vs. 29%, whereas thrombocytopenia was generally mild. Grade 3 febrile neutropenia was observed in 4 and 1 pts, none of whom further developed grade 5 toxicity. Other grade 3 or greater non-hematological adverse events included fever (B: 1 pt), pneumonitis (B: 1 pt), liver dysfunction (B: 2 pts), skin rash (B: 1 pt), and all of them were improved with an appropriate supportive care. Conclusions: The trial suggests that docetaxel monotherapy remains a standard therapy for NSCLC pts who relapsed to platinum-based chemotherapy. No significant financial relationships to disclose.

Abstract
e19029 Background: We previously conducted a phase I trial of combination chemotherapy with irinotecan and amrubicin for NSCLC and found acceptable toxicity profiles with a favorable efficacy in patients with pretreated NSCLC. The aim of this phase II trial was to further evaluate its efficacy and toxicity in this population with a long-term follow-up. Methods: Primary endpoint was objective response. Patients with NSCLC previously treated with one or two chemotherapy regimens were enrolled in this trial. Irinotecan and amrubicin were both administered on days 1 and 8, every 3 weeks at doses of 100 and 40 mg/m2, respectively. Response and toxicity were assessed according to the RECIST guideline and NCI-CTC for AE v3.0. Results: Thirty-one pretreated NSCLC patients were enrolled between 2004 and 2006. A median number of courses administered was 3 (range: 1 to 6). All patients and courses were assessable for efficacy and safety. Demographics of the patients were as follows: M/F:21/10, Ad/others:21/10, ECOG-PS 0/1:12/19, and smoker/non-smoker:21/10. Platinum-based regimens were commonly used as the prior chemotherapy. Objective response was obtained in 9 of the 31 patients with a response rate of 29.0% (95%CI: 12.1–46.0%). Grade 4 leukopenia and neutropenia were observed in 6 (19%) and 14 (45%) patients, respectively, whereas thrombocytopenia were generally mild. Grade 3 febrile neutropenia was observed in 7 patients (23%), of whom two patients further developed Grade 4 and 5 septic shock each. Other grade 3 or greater non-hematological toxicities included diarrhea, vomiting, pneumonitis, liver dysfunction in 4, 1, 1 and 2 patients, respectively. With a median follow-up time of 24.2 months, median survival time and median progression-free survival time were 14.2 and 4.0 months, respectively. Conclusions: This combination seemed highly effective for pretreated NSCLC with an acceptable toxicity. No significant financial relationships to disclose.

Abstract
e19021 Background: Few studies have formally assessed whether treatment outcomes for patients with extensive-disease small-cell lung cancer (ED-SCLC) enrolled in Phase III trials have improved substantially over the years. This investigation determined the trends in the outcomes for the patients in those trials. Methods: We analyzed trials that were reported between January 1991 and August 2008. Phase III randomized controlled trials were eligible if they compared first-line, systemic chemotherapy for ED-SCLC. Data were evaluated using linear regression analysis. Results: We identified 55 trials initiated between 1980 and 2006, involving 10,407 patients with 116 chemotherapy arms. The number of randomized patients and the proportions of patients with good performance status (PS) increased with the passage of time. In the 1990s, increasing numbers of studies examined cisplatin-based regimens, especially cisplatin and etoposide (PE) regimens, while decreasing numbers examined cyclophosphamide, doxorubicin, and vincristine-based regimens. A scattergram of the parameters ‘year of trial initiation’ and ‘median survival time’ (MST) indicated that MST increased 0.024 months (0.71 days) per year (P = 0.198). The multiple regression analysis showed no significant survival improvement over the years (regression coefficient for the year of trial initiation = 0.004, P = 0.980). In addition, the use of PE regimens did not prolong survival, whilst the proportion of good PS patients and the assignment of prophylactic cranial irradiation were significantly associated with favorable outcomes. Conclusions: The survival of patients with ED-SCLC enrolled in phase III trials has not improved significantly over the years, suggesting the need for a breakthrough, such as the discovery of novel molecular targets.

Abstract
7547 Background: Chemoradiotherapy (CRT) is a standard treatment for unresectable locally advanced non-small cell lung cancer (LA-NSCLC), but the treatment outcomes have remained unsatisfied. Thus, more effective and feasible CRT is urgently needed to improve their survival. S-1 is a newly developed oral 5-fluorouracil derivative and has synergistic effects with radiation. However, the role of S-1 in CRT for LA-NSCLC has been undetermined. Methods: We conducted two phase I trials to define the maximum tolerated doses (MTDs) and dose-limiting toxicities (DLTs) of S-1-based chemotherapy when combined with concurrent thoracic radiation (total dose of 60 Gy with 2 Gy per daily fraction) for LA-NSCLC. OLCSG 0501 was designed to evaluate the two cycles of combination of S-1 (days 1–14) and cisplatin (days 1 and 8) for patients aged 75 or younger. S-1/cisplatin dosages (mg/m2) were escalated as follows: 60/30, 60/40, 70/40, 80/40, and 80/50. The other trial, OLCSG 0502, recruited patients aged 76 or older and evaluated S-1 alone. S-1 dosages (mg/m2) were increased as follows: 60, 70, and 80. Results: A total of 44 previously untreated LA-NSCLC patients were enrolled (22 in both trials). The MTDs for S-1/cisplatin and S-1 alone were determined to be 80 mg/m2/day / 50 mg/m2 and 80 mg/m2/day, respectively. In the OLCSG 0501, DLTs included febrile neutropenia, thrombocytopenia, bacterial pneumonia and delayed second cycle of chemotherapy. No patient experienced grade 3 or more acute radiation pneumonitis and only one patient experienced grade 3 radiation esophagitis. In the OLCSG 0502, the DLTs were febrile neutropenia, stomatitis and delayed second cycle of chemotherapy. The overall response rates in OLCSG 0501 and OLCSG 0502 were 86.4% and 59.1%, respectively. Conclusions: These results indicate that S-1-based concomitant CRT would be a feasible treatment option and further phase II trials are currently under way.

Association between incremental gains in the objective response rate and survival improvement in phase III trials of first-line chemotherapy for extensive disease small-cell lung cancer.

Abstract
BACKGROUND The duration of, resources required for and cost of clinical trials could be reduced if a surrogate end point was to be used in place of survival. We assessed the extent to which the objective response rate (ORR) is predictive of mortality, how much difference in the ORR is needed to predict an obvious survival difference and what factors could affect the association between the two parameters during the first-line treatment of extensive disease (ED)-small-cell lung cancer (SCLC). METHODS We used the ORRs and median survival times (MSTs) from 48 phase III trials of first-line chemotherapy involving 8779 randomised patients with ED-SCLC in a linear regression analysis. The MST difference was calculated as the difference in MST between the investigational and reference arms; the ORR difference was similarly defined. RESULTS ORR difference between the treatment arms was modestly associated with the MST difference in the overall trials (R(2) = 0.3314). In contrast, the relationship was stronger among only trials in which prophylactic cranial irradiation was given to those having an objective response to the initial chemotherapy (R(2) = 0.6279). In this trial setting, large differences in ORR were needed to predict a survival advantage (1.2-day survival advantage per 2% increase in ORR). CONCLUSIONS In the first-line treatment of ED-SCLC, a favourable relationship was detected between the two parameters in the selected trial setting. Large ORR differences were needed to predict a survival benefit, clearly suggesting the need for new chemotherapeutic agents.

Abstract
18111 Background: Amrubicin, a totally synthetic anthracycline, is a topoisomerase II inhibitor and highly effective for non-small cell lung cancer (NSCLC) as a single agent with response rates of 25% to 28%. We previously conducted a phase I trial of combination chemotherapy with irinotecan and amrubicin for NSCLC and found acceptable toxicity profiles with a favorable efficacy in patients with pretreated NSCLC. The aim of this phase II trial was to further evaluate its efficacy and toxicity in this population. Methods: Primary endpoint was objective response. Patients with NSCLC previously treated with one or two chemotherapy regimens were enrolled in this trial. Irinotecan and amrubicin were both administered on days 1 and 8, every 3 weeks at doses of 100 and 40 mg/m2, respectively. Response and toxicity were assessed according to the RECIST guideline and NCI Common Terminology Criteria for Adverse Events v3.0. Results: Thirty-one pretreated NSCLC patients were enrolled between 2004 and 2006. A median number of courses administered was 3 (range: 1 to 6). All patients and courses were assessable for efficacy and safety. Demographics of the patients were as follows: M/F: 21/10, Ad/others: 21/10, ECOG-PS 0/1: 12/19, and smoker/non-smoker: 21/10. Platinum-based regimens were commonly used as the prior chemotherapy. Objective response was obtained in 9 of the 31 patients with a response rate of 29.0% (95%CI: 12.1–46.0%). Grade 4 leukopenia and neutropenia were observed in 6 (19%) and 14 (45%) patients, respectively, whereas thrombocytopenia were generally mild. Grade 3 febrile neutropenia was observed in 7 patients (23%), of whom two patients further developed Grade 4 and 5 septic shock each. Other grade 3 or greater non-hematological toxicities included diarrhea, vomiting, pneumonitis, liver dysfunction in 4, 1, 1 and 2 patients, respectively. At the time of this analysis with a median follow-up time in the surviving patients of 7.5 months, median survival time and median progression-free survival time were 11.9 and 4.0 months, respectively. Conclusion: This combination seemed highly effective for pretreated NSCLC despite the moderate toxicity profiles. Development of efficient patient selection is needed to avoid the serious toxicities.

Abstract
7670 Background: The relationship between EGFR mutation status and clinical outcome has not fully been assessed in NSCLC patients receiving cytotoxic agents. The aim of this study was to clarify its association. We also examined if this association could be affected by the prior gefitinib treatment or not. Methods: Patients with advanced or postoperative recurrent NSCLC who received both cytotoxic chemotherapy and gefitinib monotherapy through their treatment course and whose tumors were assessable for EGFR mutation analysis were included in this study. EGFR mutation was determined in exons 19 and 21 by direct sequencing. Results: Sixty patients were included in the study, including 6 (10%) patients who received the first-line gefitinib monotherapy followed by cytotoxic chemotherapy in the second-line or later settings. Of the 54 (90%) patients, 22 also underwent subsequent cytotoxic chemotherapy after the relapse to gefitinib monotherapy. EGFR mutations were detected in 17 (28%) patients. In the first-line cytotoxic chemotherapy setting (n=54), EGFR mutations significantly affected progression-free survival (PFS) with 6-month PFS rates of 45.8 vs. 21.9% (p=0.05). This was also observed in the multivariate analysis (HR=0.42, p=0.04). EGFR mutation was also significantly correlated with overall survival (OS) in the multivariate analysis (HR=0.26, p <0.01). Contrary, in the 28 (47%) of 60 patients who received cytotoxic chemotherapy after gefitinib monotherapy, there were no differences in PFS stratified by EGFR mutation status. The sensitivity to gefitinib was, however, correlated with EGFR mutation status and its sensitivity was retained even in the second-line setting in patients with EGFR mutations. Conclusion: EGFR mutation was significantly associated with better PFS in the first-line cytotoxic chemotherapy regimens. However, its association was not observed in the cytotoxic regimens administered after the relapse to gefitinib monotherapy, while the sensitivity to gefitinib was associated with EGFR mutation even in the second-line or later setting.

Abstract
18162 Background: The Factors affecting survival after gefitinib treatment in patients with non-small cell lung cancer (NSCLC) remain to be fully elucidated, although epidermal growth factor receptor (EGFR) mutation is a substantial prognostic factor. KL-6 has been studied as a useful indicator for interstitial lung diseases, however, it was first discovered as a pulmonary adenocarcinoma-related antigen. The aim of this study was to investigate the prognostic value of the serum KL-6 levels in advanced NSCLC patients treated with gefitinib and thus determine its association with the EGFR mutation status. Methods: Between September 2002 and September 2005, 41 patients with NSCLC were treated with gefitinib after having their serum KL-6 levels measured at Okayama University Hospital. EGFR mutations were analyzed by direct sequence methods. Results: The serum KL-6 levels ranged from 199 to 9080 U/ml (median, 550 U/ml), and 54% of 41 patients showed a level higher than the cut-off level of 500 U/ml. The median progression-free survival (PFS) time and the median overall survival (OS) time were 4.7 months and 13.9 months, respectively. Multivariate analyses revealed that the elevated KL-6 level was an independent adverse prognostic factor for PFS (hazard ratio: 2.278, p = 0.040) as well as OS (hazard ratio: 4.858, p = 0.002) in NSCLC patients treated with gefitinib. The EGFR mutation status was analyzed in 22 patients (54%). Among those with wild-type EGFR, the patients with high serum KL-6 levels also had a worse survival than those within normal serum KL-6 levels (6.5 months versus 13.3 months, p = 0.0194). Conclusions: Our data suggest that NSCLC patients with high serum KL-6 levels tended to have a poor clinical outcome when treated with gefitinib. No significant financial relationships to disclose.

Abstract
17029 Background: The aim was to evaluate the utility of an early change in CEA levels for predicting subsequent gefitinib sensitivity in NSCLC patients. Methods: CEA level was measured before and after the beginning of gefitinib treatment (day1) in 110 (91%) of consecutive 121 patients. Daily decline rate of CEA was simply defined for each patient as follows: (M0−Mx)/Dx/M0*100(%), with the baseline level (M0), the level on days × (Mx), and days from day 1 to day X (Dx). Results: Patient characteristics were as follows; median age: 62, M/F: 61/39%, Ad/others: 84/16% and smoker: 66%. Objective response rate and disease control rate were 28.2% and 74.5%, respectively. Median baseline CEA level was 12.6 ng/mL. Daily decline rate of CEA level from day 1 to the date on which confirmation of objective response was performed significantly differed among the response categories; median decreases in percentages were 0.86, 0.06, and −1.52%/day in CR/PR, SD, and PD patients, respectively (p < 0.0001). This association was more evident in the 70 patients with abnormal baseline CEA level (≥5.0 ng/mL). A cutoff level of −0.58% decrease per day most accurately reflected tumor shrinkage in the 70 patients, with sensitivity, specificity, and positive and negative predictive values for disease control (CR/PR/SD) of 89.1, 73.3, 92.5 and 64.7%, respectively. Among 49 (41%) patients reassessed CEA levels within the first 2 weeks since day 1, 41 could continue the treatment without any disease progression during this period. The daily decline rate in this early phase tended to differ between the responses (median; 1.57 and −0.50% in CR/PR/SD and PD, respectively; p = 0.0975), and less exactly reflected disease control with sensitivity, specificity, and positive and negative predictive values of 82.1, 40.0, 88.5, and 28.6%, respectively when a cutoff of −0.58% was applied. Conclusion: Degree of change in CEA level from the start of gefitinib treatment to confirmation of objective response significantly correlated with tumor shrinkage. As a predictor for obtaining disease control, monitoring early change in CEA level might be useful due to high sensitivity and positive predictive value, in spite of low specificity for detection of PD patients.

Abstract
7101 Background: Standard treatment of locally advanced non-small cell lung cancer (NSCLC) is cisplatin-based chemotherapy with concurrent thoracic radiation therapy (TRT). Furuse et al. demonstrated a superiority of mitomycin, vindesine and cisplatin (MVP) chemotherapy with concurrent TRT over that with sequential TRT (JCO 17, 1999). We demonstrated that docetaxel plus cisplatin (DP) chemotherapy with concurrent TRT shows better response rate and survival (Kiura K et al. BJC 89, 2003). We conducted a randomized phase III trial that compared DP with MVP in locally advanced NSCLC patients when concurrently administered with TRT. Methods: We randomly assigned patients with good performance status (PS)-stage IIIA/IIIB NSCLC to receive DP or MVP chemotherapy. Chemotherapy consisted of docetaxel 40 mg/m2 and cisplatin 40 mg/m2 on days 1, 8, 29, & 36 in the DP arm and mitomycin 8 mg/m2 on days 1 & 29, vindesine 3 mg/m2 on days 1, 8, 29, & 36, and cisplatin 80 mg/m2 on days 1 & 29 in the MVP arm. In the both groups, TRT began on day 1 at a dose of 60 Gy (2 Gy per fraction and 5 fractions per week for a total of 30 fractions). Results: Two hundred patients entered the trial between July 2000 and July 2005. Pretreatment characteristics were well balanced between the two treatment arms as follows: male/female 92/7, 88/13; median age (range) 65 (40–75), 64 (34–75); stage IIIA/IIIB 33/66, 33/68; and PS of 0/1 46/53, 50/51, for the DP arm and for the MVP arm, respectively. The response rates for the DP arm and the MVP arm were 78.8% and 70.3%, respectively. The 1- and 2-year survival rates were 81.8% and 59.9% for the DP arm, and were 68.8% and 49.1% for the MVP arm, respectively. Median follow up time is 1.4 years in January 2006. Complete analysis will be fixed in July 2007. Conclusions: The DP arm is exactly reproducing the response rate and survival of the phase II trial we have previously reported. The MVP arm seems to reveal better results than that we expected. Radiation dose and schedule might explain the difference because Furuse et al. splitted 56 Gy of TRT in the MVP arm whereas we did not split 60 Gy of TRT.

Abstract
20047 Background: Factors affecting long-term survival after postoperative recurrence in non-small cell lung cancer (NSCLC) patients have not been fully understood. Furthermore, molecular features of them also have remained undetermined. The aim of this study was to identify these possible factors and to investigate their association with epidermal growth factor receptor (EGFR) mutation. Methods: Fifty-eight patients with postoperative recurrent NSCLC treated at Okayama University Hospital between January 1999 and December 2003 were retrospectively analyzed. We defined those surviving for 2 years or longer after postoperative recurrence as long-term survivors. Tumor samples for EGFR mutation analysis were available in 32 (55%) patients and were examined in exons 18 to 21 of EGFR using direct sequence method. Results: Demographics of 58 patients were as follows: median age 65 years (range, 33–85 years), male/female, 69%/31%; adenocarcinoma/others, 69%/31%; ever/never-smokers, 66%/34% and local/local and distant/distant recurrence; 29%/10%/61%. Median survival time and 1-year survival rate for 58 patients were 22.7 months and 79%, respectively, with a minimum follow-up time of 2 years. Half of 28 long-term survivors did not have any smoking history, whereas only 6 never-smokers were included in the remaining 30 patients who died within 2 years, indicating that never-smoking history is significantly associated with long-term survival (p=0.016). In multivariate analysis, never-smoking history was a significant predictive factor for long-term survival (Odds ratio 4.90, 95% confidence interval: 1.26–19.00, p=0.022). Among 32 patients analyzed for EGFR mutation, patients harboring EGFR mutation in ever-smokers and in never-smokers were 10% and 82%, respectively. Seven (47%) of 15 long-term survivors analyzed had EGFR mutation; however, only 4 (24%) of 17 patients who died within 2 years did (p = 0.169). Conclusions: Our data suggest that never-smoking history might have a favorable effect on long-term survival in postoperative recurrent NSCLC patients, and long-term survivors tend to have EGFR mutation.

Abstract
7147 Background: Although concurrent chemoradiotherapy (CT/RT) is associated with increased survival for patients (pts) with locally advanced non-small cell lung cancer (NSCLC), long-outcomes beyond 5 years have not been fully analyzed. Methods: Between 1994 and 1999, we conducted two phase II studies examining concurrent CT/RT for treatment of surgically unresectable stage IIIA or IIIB NSCLC. One regimen consisted of three cycles of 5-fluorouracil 500mg/m2 and cisplatin 20mg/m2, days 1–5, every 4 weeks and concurrent hyperfractionated thoracic RT (1.25Gy twice daily, total 62.5–70Gy) [FP-TRT] (Segawa et al. BJC 82, 2000). The other consisted of docetaxel 40mg/m2 and cisplatin 40mg/m2, days 1, 8, 29 and 36 and concurrent thoracic RT (2Gy daily, total 60Gy) [DP-TRT] (Kiura et al. BJC 89, 2003). Long-term data is presented. Results: In 50 pts treated with FP-TRT, the median survival time (MST) was 1.6 years (yr; 95% confidential interval [CI]: 0.91 - 2.25 yr) by a median follow-up time of 10.4 yr and the actual 5 yr-survival rate was 30%. In 15 long-term survivors, 3 and 2 pts died due to primary NSCLC and secondary primary cancer (SPC), respectively, 1 was lost to follow-up, and 9 are still alive. In 42 pts treated with DP-TRT, the MST was 2.1 yr (95% CI: 0.82 - 2.48 yr) by a median follow-up time of 6.3 yr and the actual 5 yr-survival rate was 31%. In 13 long-term survivors, 1 pt died due to primary NSCLC, 1 died due to SPC, 1 was lost to follow-up, and 10 are still alive. Overall, 7 of 92 pts enrolled in these studies developed SPCs (2 NSCLC, 1 small cell lung cancer, 2 esophageal cancers, 2 gall bladder cancers) although no pts developed leukemia or myelodysplastic syndrome. An observed incidence rate of SPCs was 2356.1/100,000 (95% CI: 947.6 - 4856.0). Cumulative incidence was 5.8% (standard error [SE] 4.0%) at 5 yr, 10.0% (SE 5.6%) at 8 yr and 60.8% (SE 18.9%) at 10 yr. The median time from the beginning of CT/RT to the diagnosis of SPC was 9.6 yr (95% CI: 8.1 - 11.1 yr). Conclusions: Approximately 30% of pts survived more than 5 years after concurrent CT/RT, however, they were still at risk of dying from primary NSCLC. Occurrence of SPC in long-term survivors should be concerned in follow-up. No significant financial relationships to disclose.

Abstract
20059 Background: Pneumoconiosis is known to be associated with an independent increased risk of lung cancer. However, it is difficult to detect lung cancer radiographically in patient with pneumoconiosis because of pre-existing diffuse pulmonary shadows. The purpose of this study is to evaluate the usefulness of serum DNA methylation for detection of pneumoconiosis-associated lung cancer. Methods: We investigated to identify promoter methylation status of RAR-beta, p16INK4a, MGMT, DAPK, and RASSFIA gene in serum DNA using methylation-specific PCR. Sera were obtained from 31 control patients with non-malignant-non-pneumoconiotic pulmonary disease (Group I), 36 with pneumoconiosis (Group II), and 5 with pneumoconiosis-associated lung cancer (Group III). DNA was extracted using QIAamp DNA Blood Midi Kit (Qiagen, CA). Following DNA bisulfite modification using CpGenome DNA Modification Kit (Intergen, NY), PCR was performed with primers for methylated or unmethylated promoter sequences. Results: Median (range) age of patients were 61 (26–78), 71 (49–86), and 69 (56–78) for Group I, II, and III respectively. Median (range) duration of silica and asbestos exposure were 33 (3–47) years and 33(32–40) years for Group II and III respectively. All of 5 pneumoconiosis-associated lung cancer were adenocarcinoma. Eleven patients (35.5%) in Group I, 19 patients (52.8%) in Group II, and 5 patients (100%) in Group III were shown to have methylation of at least one gene. The total number of methylated genes per patient were, 0.35, 0.69, and 1.20 for groups I, II, and III respectively (p = 0.013, Kruskal-Wallis analysis). In Group II, methylation status did not correlate with duration of occupational exposure, smoking history, radiographic findings, and age. Conclusions: In patients with pneumoconiosis, monitoring of aberrant promoter methylation of serum DNA might be useful for assessing the risk of lung cancer and early detection of lung cancer.
