Abstract
OBJECTIVE The Stroke Angel initiative investigates the implementation of telemedicine for improvement of preclinical communication between emergency medical services (EMS) and stroke units in cases of acute stroke. MATERIAL AND METHODS Stroke Angel is a technical system for the telemedical prenotification of patients in cases of suspected stroke at a stroke unit by the EMS. Within the framework of an observational study, the team has been investigating the effects of the system on door-to-computed tomography (CT) and door-to-needle times as well as the lysis rate in the neighboring regions of Rhön-Grabfeld and Bad Kissingen since 2005. RESULTS The system supports the acute treatment of neurological emergencies and functions as a catalyst for the interlinking of medical institutions in the region as well as for communication between emergency physicians/EMS and hospital physicians. The use of a computer-based data collection enables a continuous improvement process leading to an acceleration of internal clinical procedures and an increase of the lysis rate with the mortality rate staying constant. CONCLUSION Telemedicine is applicable in the preclinical care of acute stroke and, thanks to the computer-based data collection, leads to an increase in process transparency, which helps to improve the internal clinical processes in and around a stroke unit.

Abstract
630 Background: Reintroduction of oxaliplatin seems to have clinical benefits for patients with metastatic colorectal cancer refractory to standard chemotherapy regimens. A interim analysis of RE-OPEN study reported 38.9% of disease control rate (DCR) in ASCO GI 2013, but it is still unknown who will receive benefits from reintroduction of oxaliplatin. Methods: Among patients in whom oxaliplatin was reintroduced in the 7 participating hospitals, we retrospectively studied patients who had previously received oxaliplatin and irinotecan and patients who had a response of stable disease or better during initial treatment with oxaliplatin. Results: From June 2009 through January 2013, oxaliplatin was reintroduced in 53 patients (31 men and 22 women). The median age was 64 years, and the performance status was 0 in 24 patients and 1 in 29. The reasons for discontinuing initial treatment with oxaliplatin were progressive disease in 36 patients, adverse events in 14 and others in 3. The response rate (RR), DCR, the median progression-free survival (PFS), and the median overall survival were 3.8%, 47.2%, 105 days, and 313 days, respectively. As for adverse events, allergic reactions to oxaliplatin (grade 1 or higher) occurred in 26% of the patients. RR, DCR, and PFS in 44 patients with the oxaliplatin-free-interval (OFI) over 6 months were 4.6%, 54.6%, and 119 days, respectively, and were statistically better than those in 9 patients with OFI less than 6 months (0%, 11.1%, and 84 days). Reintroduction of oxaliplatin with bevacizumab showed better PFS than that without bevacizumab (114 days and 78 days, respectively). Conclusions: Reintroduction of oxaliplatin was suggested to be one option for the management of colorectal cancer that is resistant to standard therapy, especially in patients with OFI over 6 months. Bevacizumab may enhance the results of reintroduction treatment.

Abstract
BACKGROUND In July 2008, cetuximab treatment for unresectable advanced or recurrent colorectal cancer was approved in Japan, but there have been few reports on this therapy in Japan. PURPOSE We retrospectively analyzed the efficacy and safety of cetuximab(Cmab)+irinotecan(CPT-11)for unresectable advanced or recurrent colorectal cancer from October 2008 to April 2010 at 5 centers in the Kanagawa region. PATIENTS AND METHODS The number of patients enrolled was 38, all of whom were treated after second-line therapy. RESULTS The RR was 24%. DCR was 68%. TTF was 105 days and OS was 242 days. CONCLUSION At 5 centers, Cmab+CPT-11 was an effective and safe treatment after second-line therapy.

Abstract
463 Background: Cetuximab and chemotherapy as first-line therapy for patients with KRAS wild type prolong survival. However, COIN trial has not demonstrated the survival benefit of FOLFOX or XELOX and cetuximab therapy. Few data are available on its benefit for patients with KRAS and BRAF wild-type. Methods: The aim of this study was to assess the efficacy of first-line FOLFOX or bi-weekly XELOX and bi-weekly cetuximab in KRAS/BRAF wt mCRC. Chemonaive patients received FOLFOX or biweekly XELOX (oxaliplatin 85 mg/ m2/day 1 plus capecitabine 2000/m2/days 1-7) and biweekly cetuximab 500mg m2/ day 1 every 2 weeks. Primary endpoint was response rate(RR), other secondary endpoints were PFS, OS, DCR, safety, DI and resection rate. KRAS test (codon12,13) and BRAF test (V600E) by direct sequence were performed in Yamaguchi University. Patients with KRAS/BRAF wt were enrolled in this study. The regimen of FOLFOX or XELOX were selected by investigator’s preference, not randomized. Results: From April 2010 to May 2011, 139 pts were preregistered. KRAS and BRAF were examined from paraffin-embedded sample. 70 (50.3%) pts were KRAS/BRAF wt, and 62 pts were enrolled: The main characteristics of the entered pts were: sex (M/F) 34/28, median age 66 yrs (range 34-83 yrs). Grade 3/4 adverse events were leucopenia 4.8%, neutropenia 25.8%, skin toxity (paronychia/fissure) 9.7%, and acne 9.7%. Two CR (3.2%) and 40 PR (64.5%), 15 SD (24.2%) and 3 PD (4.8%) 2NE were observed, with an overall response rate of 67.7% and a disease control rate (CR+PR+SD) of 91.9%. The RR of FOLFOX or XELOX were 64.9% (24/37) and 72.0% (18/25), DCR were 89.2% and 96% respectively. Conclusions: FLEET was the first multicenter phase II study with prospective KRAS/BRAF analysis as a predictive biomarker for cetuximab in first-line mCRC in Japan. Results of this study indicate that both biweekly combination regimens are feasible, tolerable, and clinically active. Biweekly XELOX+cetuximab study (FLEET2) is ongoing. Clinical trial information: UMIN000003253.

Abstract
We analyzed the relationship between Onodera's prognostic nutritional index(PNI), classified by serum albumin level, lymphocyte level, and clinicopathological features, in 46 patients with unresectable or recurrent colorectal cancer being treated with chemotherapy.Onodera 's PNI was distributed between 29.7 and 56.1(average 45.4±6.8 ).Onodera 's PNI showed a significant correlation with performance status and surgery before chemotherapy(p=0.002 and 0.002, respectively).Next, all patients were divided into two groups according to their Onodera's PNI values, based on the receiver operator characteristic curve.We found that Onodera's PNI showed a significant correlation with overall survival times(median survival time, 548 days(Onodera's PNI<47.8 ), 902 days(Onodera's PNI≥47.8 ), p=0.00065 ).This PNI could be a prognostic factor and a very useful objective screening tool for assessing the nutritional condition of those with unresectable or recurrent colorectal cancer being treated with chemotherapy.

Abstract
A 55-year-old woman was found to have a type-4 lesion centered on the greater curvature of the lower portion of her stomach during an upper gastrointestinal endoscopic examination.A diagnosis of inoperable advanced gastric carcinoma [type 4, tub 2/por, T3 (SE), N3, H0, P1, cStage IV], complicated by pyloric stenosis, liver dysfunction, and obstructive jaundice untreatable by bile drainage, was made.After obtaining the informed consent of the patient and her family and explain- ing that under the circumstances surgery was not indicated, chemotherapy [S-1 (granules) 80 mg/m2, CDDP 60 mg/m2] was selected. After starting treatment, an improvement in liver dysfunction and jaundice was observed, and at the start of the second course, the patient had become capable of oral feeding.The patient was discharged after completion of the second course. No choices associated with evidence exist for treatment of patients with inoperable advanced gastric cancer (complicated by obstructive jaundice), who are not elderly and have good performance status (PS).We report this case in which improvement of activity of daily living (ADL) was achieved relatively safely by treatment with S-1/CDDP, together with a brief discussion based on the literature.

Abstract
e19087 Background: Docetaxel and platinum is active in patients with non-small cell lung cancer (NSCLC) as first-line chemotherapy, and docetaxel is also effective in previously-treated patients. This study was designed to evaluate activity and toxicity of docetaxel and carboplatin as second-line chemotherapy in advanced NSCLC patients treated with non-platinum regimens. Methods: Patients with stage IIIB or IV NSCLC treated with non-platinum regimens, a performance status ≤ 2, and an adequate organ function were eligible. Patients were treated with docetaxel 50 mg/m2/day and carboplatin AUC 5 mg/ml/min on day 1 of each 21-day cycle. Primary endpoint was response rate. Results: Twenty-nine patients with a median age of 63 years were included. Median number of cycles for docetaxel and carboplatin was 3.2. Grade 3/4 neutropenia and anemia occurred in 21 (72.4%) and 2 patients (7.0%), respectively. Febrile neutropenia occurred in 2 patients (7.0%). Grade 3 non-hematological toxicity included diarrhea and peripheral neuropathy in each 1 patients (3.5%). Complete and partial response was observed in 1 and 4 patients, respectively. Overall response rate was 17.2% (95%CI: 5.9–35.8). Median survival time was 12.7 months (95%CI: 7.8–17.6) and 1- year survival rate was 52.5% (95%CI: 31.8–73.2). Conclusions: The combination of docetaxel and carboplatin as second-line chemotherapy may be promising in advanced NSCLC patients treated with non-platinum regimens. No significant financial relationships to disclose.

Abstract
18071 Background: The combined modality of the third generation new agent plus cisplatin with concurrent TRT is considered ideal for locally advanced non-small cell lung cancer. However, it is difficult to conduct because of severe toxicities. Methods: Patients fulfilling the following eligibility criteria were enrolled: previously untreated, good performance status (PS 0–2), age <75, stage III, and adequate organ function. The patients received irinotecan 60 mg/m2 i.v. on days 1, 8 and 15, and cisplatin 80 mg/m2 i.v. on day 1 in the first group. The doses were reduced to 50 and 60 mg/m2 in the second group, respectively. Two cycles of chemotherapy were repeated every 4 weeks. Thoracic radiotherapy of 2 Gy/day commenced on day 2 of each chemotherapy cycle, with 28 and 32 Gy administered in the first and second cycles, respectively. Primary endpoint and objective sample size were response rate and 45 patients, respectively. Results: Fifty patients were eligible and 48 (16 in the 1st, 32 in the 2nd group) patients were assessable for response, toxicity and survival. The overall response (OS) was 83% (95% confidence interval (CI), 70–93%). Grade 4 leukopenia, neutropenia, grade 3 or 4 diarrhea, pneumonitis, esophagitis and fatigue occurred in 21%, 48%, 19%, 10% and 19%, respectively. The median time to progression was 8.2 months. The median overall survival time (MST), and the 2- and 5-year survival rates were 20.1 months, 47.1% and 17.1%, respectively. In subgroup analysis, the OS of 1st and 2nd groups were 75% and 88% (not significant), respectively. The MST of 1st and 2nd groups were 13.1 and 33.4 months, respectively, and significant favor with 2nd group (p=0.011). The execution rates of irinotecan on day 15 were significant higher in 2nd (22% vs. 48%) groups (p=0.032), and the survival separated by execution times on day 15 were significantly favor with higher execution time group (p=0.026). Conclusions: This therapy is active and further investigations are warranted at the 2nd group dose level. High execution of chemotherapy on day 15 may be important for the achievement of concurrent chemoradiotherapy. No significant financial relationships to disclose.

Abstract
Flail chest occurs by blunt chest trauma and is associated with pulmonary contusion, atelectasis, pneumothorax, hemothorax, and respiratory failure. Because of its severity, it may need internal pneumatic stabilization or surgical fixation. Some patients do not need the internal stabilization and are observed conservatively. Some of these patients, however, increase the flail after palliating the pain and getting up. These patients show inefficient ventilation and surgical fixation is needed. The operation should be performed after the improvement of pulmonary contusion. In this paper, we presented 2 patients who showed such course and clarified the surgical methodology.

Abstract
17108 Background: VNR is one of standard drugs for elderly NSCLC. The role of platinum- based combination chemotherapy for elderly pts is controversial. Methods: Based on our phase I study (Fukuda, et al, abstract 2763, ASCO 2002), we conducted a phase II single arm study of VNR combined with CBDCA for elderly NSCLC pts. Primary endpoints were response and toxicity. Eligibility criteria included: chemotherapy-naïve, good performance status (PS: 0–2), age ≥75, stage IIIB-IV, and adequate hematological, hepatic and renal function, written informed consent. Treatment consisted of VNR 20 mg/m2 i.v. on days 1 and 8 and CBDCA target AUC = 4 (Chatelut formula, Jaffe method) on day 1 of every 4 weeks. Planned sample size was 40. Results: A total of 40 pts were enrolled. Pts characteristics: male/female = 30/10, PS 0/1 = 18/22, median age (range) = 78 (75–86), Ad/Sq/Others = 30/9/1, stage IIIB/IV = 14/26. Forty pts were eligible and assessable for toxicity and survival, and 37 pts were assessable for response on the submission of this abstract. Thirty-three pts were treated with two or more courses of treatment. Overall response rate was 13.5% (95% CI, 4.5%-28.8%); CR= 0, PR= 5, SD = 23, PD = 9. Grade 3 or 4 leukopenia, neutropenia, and anemia were observed in 31.6%, 50.0%, and 7.1%, respectively. Treatment-related death did not occurred. Non-hematological toxicity was mild. The median survival time was 392 days (95% CI, 311–474) and the median time to progression was 114 days. Conclusions: This combination is well-tolerated and modest activity in pts with elderly NSCLC. No significant financial relationships to disclose.

Abstract
2009 Background: Little is known about the relationship between the pharmacokinetics and efficacy of gefitinib. Methods: Plasma trough levels of gefitinib were measured on days 0, 3 (D3), and 8 (D8) by HPLC in advanced NSCLC patients treated with gefitinib 250 mg daily. Eligibility criteria included: performance status (PS) ≤ 3, age ≤ 80, stage IIIB-IV, and written informed consent. Results: Fifty patients were enrolled, and 44 patients were assessable. The median [25%-75%] values of D3 and D8 was 662 [440–937] and 1064 [782–1405] ng/ml, respectively. D8/D3 rate was categorized by 1.587 of the median value. In 44 patients, the median time to progression (TTP) was 83 days, and the median overall survival (OS) was 224 days. The differences in TTP were compared by Kaplan-Meier method and log-rank test: D8/D3 (high D8/D3, median 209 days vs. low D8/D3, 43 days; P = 0.0299), smoking (never-smokers, 224 days vs. smokers, 32 days; P = 0.0467), and histology (adenocarcinoma, 97 days vs. non-adenocarcinoma, 27 days; P = 0.0096). Sex, age, PS, previous treatments, and the use of antacids were not significant. Multivariate analysis showed that TTP was associated with D8/D3 (hazard rate, 95%CI; 0.458, 0.234–0.898) and smoking (2.005, 1.030–3.903). Never-smokers with high D8/D3 showed the best TTP, and smokers with low D8/D3 showed the worst TTP. Never-smokers with low D8/D3 and smokers with high D8/D3 showed similar TTP curves. In contrast, OS was associated with smoking (hazard rate, 95%CI; 3.182, 1.506–6.724), but not D8/D3. Conclusions: High D8/D3 was independently associated with better TTP in gefitinib-treated NSCLC patients. Our findings suggest that pharmacokinetics of gefitinib may be involved in its anti-tumor activity. No significant financial relationships to disclose.

Abstract
Telomerase is an enzyme required by actively dividing cells to maintain the ends of chromosomes (telomeres). It is present in germline tissue, stem cells and cancer cells, but is repressed in somatic cells. Efforts are underway to exploit this selective expression of telomerase in cancer therapeutics. This review describes the status of telomerase research, which although at present predominantly preclinical, has the potential to enter clinical research.

Abstract
Autoantibodies against heat shock protein 40 (HSP40) and their clinical significance in ulcerative colitis (UC) have not been evaluated before. Twenty-six tissue specimens of inflamed areas from patients with UC, 16 from patients with Crohn's disease (CD) and 16 endoscopically normal tissues were analysed for HSP40 expression. Sera from 47 patients with UC and 44 healthy volunteers were examined for the presence of autoantibodies against HSP40 by enzyme-linked immunosorbent assay test. Immunohistochemistry showed that 17 out of 26 specimens from UC patients, one specimen from a CD patient and one normal tissue specimen were positive for HSP40. Most HSP40-positive cells expressed CD68. Higher titres of anti-HSP40 autoantibodies were detected in sera from UC patients compared with healthy volunteers. In patients with inactive disease, those with proctitis or left-sided colitis had higher titres of anti-HSP40 autoantibodies than those with total colitis. Our study suggests that autoimmunity against HSP40 may have a beneficial effect in UC patients by limiting the extent of the disease.

Abstract
AIM To observe hemichrome formation in human haemoglobin A under various buffer conditions. METHOD Hemichrome formation of human oxyhaemoglobin A (HbO2) was studied spectrophotometrically in 0.1 m buffer at various temperatures and pH values. RESULTS Following autoxidation in ferrous HbO2, it was evident that formation of hemichrome, which tends to precipitate, occurred at various stages during the course of the autoxidation reaction namely at initial, intermediate or final stages, depending on temperature and pH of the solution. By varying temperature of the solution from 35 to 55 degrees C and pH from 4.5 to 10.5, it is shown here that HbO2 exhibits high susceptibility for hemichrome formation and its occurrence is a function of pH, temperature and progress of autoxidation of HbO2. Unlike HbO2 and its separated haemoglobin chains, monomeric bovine heart myoglobin (MbO2) did not easily form hemichrome. CONCLUSION These findings provide a clue on the crucial role of haemoglobin molecule for senescent cell recognition or homeostasis in the blood circulation.

Abstract
Interleukin 6 (IL-6) is a pleiotropic cytokine with many physiological functions. The present study was designed to determine the expression of IL-6 and its receptor (IL-6R) in human gastric and colorectal cancers. Nine gastric- and nine colorectal cancer cell lines were analysed. The IL-6 gene was expressed in two gastric cancer cell lines and one colorectal cancer cell line; however, most of the cancer cell lines studied expressed the IL-6R gene. The level of IL-6 secretion in the gastric cancer cell lines correlated with the level of soluble IL-6R secretion, and was significantly higher (< approximately 100 pg/ml) than the level of IL-6 secretion in the colorectal cancer cell lines (< approximately 50 pg/ml). These results suggest that IL-6 may act in a paracrine fashion rather than an autocrine fashion in these cell lines.

Abstract
We conducted a phase I study of irinotecan (CPT-11) and cisplatin with concurrent split-course radiotherapy in limited-disease small-cell lung cancer (LD-SCLC). This study aimed to determine the maximum tolerated dose (MTD) and dose-limiting toxicity (DLT) of this therapy. Four chemotherapy cycles of CPT-11 (days 1, 8 and 15) and cisplatin (day 1) were repeated every 28 days. Radiotherapy of 2 Gy/day commenced on day 2 of each chemotherapy cycle with 20 Gy administered from the first to the third cycles (a total of 60 Gy). 17 patients were enrolled at three dose levels (CPT-11/cisplatin: 40/60, 50/60 and 60/60 mg/m(2)), and 16 were evaluable for toxicity and outcome. 2 of 4 patients at 60/60 mg/m(2) refused continuation of therapy because of general fatigue, and the relative dose intensity of CPT-11 at 50/60 mg/m(2) was approximately 50%. These levels were considered as the MTD. Tumour responses included four complete responses (CR), 11 partial responses (PR) and one no change (NC), and the overall response rate was 93.8% (95% confidence interval: (CI) 71.7-98.9%). This combined modality is tolerable, and CPT-11/cisplatin of 40/60 mg/m(2) in this modality is recommended for phase II study.

Abstract
Methylthioadenosine phosphorylase (MTAP) is an important enzyme used for the salvage of adenine and methionine. Cells lacking this enzyme are expected to be sensitive to purine synthesis inhibitors and/or methionine starvation. We reported previously that the MTAP gene is deleted in adult T cell leukemia (ATL) cells. In the present study, we expanded our series and used a real-time quantitative PCR assay for accurate diagnosis of the deletion and nine of 65 primary ATL samples (13.8%) were MTAP negative. In spite of this low incidence, ATL cells showed significantly higher sensitivity to L-alanosine, an inhibitor of de novo adenosine monophosphate (AMP) synthesis, than normal lymphocytes, suggesting that the MTAP gene is inactivated not only by deletion but also by other mechanisms. Indeed, a real-time quantitative RT-PCR assay disclosed that primary ATL cells had significantly lower MTAP mRNA expression than normal lymphocytes. Since MTAP-negative ATL cell lines also showed much higher sensitivity to L-alanosine than MTAP-positive ATL cell lines, we used these cell lines to investigate whether it is possible to develop selective therapy targeting MTAP deficiency. A substrate of MTAP, methylthioadenosine (MTA) or its substitutes rescued concanavalin A (Con A)-activated normal lymphocyte proliferation from L-alanosine toxicity. All the compounds except 5'-deoxyadenosine, however, also caused the undesirable rescue of MTAP-negative ATL cell lines. 5'-Deoxyadenosine had the desired ability to rescue hematopoietic progenitor cells without rescuing ATL cell lines. These results support the rationale for a chemotherapy regimen of L-alanosine combined with 5'-deoxyadenosine rescue in MTAP-deficient ATL.

Abstract
We conducted a phase I study of paclitaxel and irinotecan (CPT-11) in advanced non-small cell lung cancer (NSCLC). This study aimed to determine the maximum tolerated doses (MTD). The pharmacokinetics of CPT-11 and its major active metabolite, SN-38, were also analysed. Patients received paclitaxel (day 1) followed by CPT-11 (days 1, 8 and 15), in a 4-week cycle, and paclitaxel and CPT-11 were escalated from 120 and 40 mg/m(2), respectively. 28 patients were enrolled, who were evaluated for toxicity. 2 of 6 patients at 210 mg/m(2) paclitaxel and 50 mg/m(2) CPT-11, and 2 of 4 at 180 and 60 mg/m(2) developed dose-limiting toxicity (DLT) (neutropenia, fever, neurotoxicity and diarrhoea). The area under the plasma concentration-time curve (AUC) of CPT-11 on day 1 was significantly higher than that on days 8 or 15 at each dose level (P=0.002). The AUC of SN-38 on day 1 was significantly increased using paclitaxel doses >or=150 mg/m(2). A preceding paclitaxel administration changed the pharmacokinetics of CPT-11 and SN-38. However, the toxicity was tolerable. Paclitaxel 180 mg/m(2) and CPT-11 50 mg/m(2) were the recommended doses for further phase II study of this combination.

Abstract
The aim of the present study was to investigate whether CYP2C19 polymorphism status and gastric emptying are related to healing in patients with gastric ulcers. We studied the CYP2C19 status in seven patients with proton pump inhibitor (PPI)-resistant ulcers, 21 with PPI-sensitive ulcers and 46 healthy volunteers using polymerase chain reaction restriction fragment length polymorphism to detect CYP2C19m1 mutation in exon 5 and CYP2C19m2 mutation in exon 4. Gastric emptying was evaluated using the 13C-acetate breath test. The frequency of phenotypes, indicated by genotypes, did not differ significantly between the three patient groups. The peak time of 13C excretion in patients with PPI-resistant ulcers was significantly longer than that of patients with PPI-sensitive ulcers and healthy volunteers. Our results suggest that rate of gastric emptying, but not CYP2C19 polymorphism, is likely to be an important factor in the delayed healing of patients with PPI-resistant gastric ulcer.

Abstract
PURPOSE Docetaxel and carboplatin have a broad spectrum of antitumor activity. We conducted a phase I study of docetaxel and carboplatin as second-line chemotherapy in previously treated non-small-cell lung cancer (NSCLC). This study aimed to determine the maximum tolerated dose (MTD) and the dose-limiting toxicities in this second-line combination chemotherapy. METHODS Patients with advanced NSCLC were treated with escalating docetaxel doses in combination with a fixed-target area under the concentration-time curve (AUC) of 5 mg min/ml of carboplatin on day 1 of a 3-4-week cycle. The carboplatin dose was determined by multiplying the AUC by the clearance predicted using the Chatelut formula. The docetaxel dose was escalated from 40 mg/m2 to the MTD by 10 mg/m2 increments. RESULTS A total of 16 patients previously treated with anticancer drugs were enrolled through three dose levels (40, 50 and 60 mg/m2 of docetaxel). All patients were assessable for toxicity and response. The MTD was docetaxel 60 mg/m2 with a carboplatin target AUC of 5 mg min/ml, and the dose-limiting toxicities in two of four patients were neutropenia and thrombocytopenia. Overall, neutropenia and thrombocytopenia of grade 3/4 occurred in eight patients (50%) and three patients (19%), respectively. Four patients (25%) and two patients (13%) experienced both grade 1 diarrhea and dermatitis, respectively. Allergic reactions, fluid retention, pneumonitis, neurotoxicity and mucositis were not observed. Of 16 patients, 5 showed an objective response (response rate 31%; 95% CI 14-56%). CONCLUSIONS The combination of docetaxel and carboplatin is a feasible and well-tolerated second-line chemotherapy regimen in the treatment of NSCLC. Docetaxel 50 mg/m2 under the carboplatin target AUC of 5 mg x min/ml using the Chatelut formula was the recommended dose for phase II study.

Abstract
Overexpression of breast cancer resistance protein (BCRP) ABCG2 reportedly confers cancer cell resistance to camptothecin-based anticancer drugs, such as topotecan and 7-ethyl-10-hydroxycamptothecin (SN-38: the active metabolite of irinotecan). We have recently shown that SN-38-selected PC-6/SN2-5H human lung carcinoma cells overexpressed BCRP with the reduced intracellular accumulation of SN-38 and SN-38-glucuronide (S. Kawabata et al., Biochem. Biophys. Res. Commun. 280, 1216-1223, 2001). In the present study, we have examined whether BCRP transports SN-38 and/or SN-38-glucuronide in vitro, by using plasma membrane vesicles from the parental PC-6 and resistant PC-6/SN2-5H cells, where SN-38 and SN-38-glucuronide accumulation in membrane vesicles was measured by HPLC. Both SN-38 and SN-38-glucuronide were ATP-dependently transported into membrane vesicles prepared from PC-6/SN2-5H cells, whereas no transport activity was observed in membrane vesicles from PC-6 cells. The kinetic parameters of the transport observed in PC-6/SN2-5H vesicles were K(m) = 4.0 microM, V(max) = 714 pmol/mg/min for SN-38 and K(m) = 26 microM, V(max) = 833 pmol/mg/min for SN-38-glucuronide. These findings suggest that BCRP expressed in PC-6/SN2-5H cells transports both SN-38 and SN-38-glucuronide with a higher affinity toward SN-38.

Abstract
Despite rapid progress in methods for analyzing radiation effects, much remains to be learned about the mechanisms and processes of radiation-induced immunological dysfunction. Among 17,899 sera obtained from atomic bomb survivors in Nagasaki, Japan, sera from 484 participants who complied with a reexamination for alkaline phosphatase (ALP) were tested for antimitochondrial antibody (AMA) by indirect immunofluorescence, and autoantibodies against 2-oxo-acid dehydrogenase complex (2-OADC) by immunoblotting to investigate the prevalence of primary biliary cirrhosis (PBC). Of these 484 sera, 28 (5.8%) were seropositive for AMA. The 484 participants were divided into three groups according to distance from the hypocenter: 72 who were exposed within 1999 m (closest group), 368 from 2000 to 5999 m (intermediate distant group), and 44 outside 6000 m (distant group). The positivity rates for AMA in these three groups were 6/72 (8.3%), 22/368 (6.0%), and 0/44 (0%), respectively (P =.08). Furthermore, high titers ( > 1:320) of AMA were observed in 3/6 (50%) AMA-positive sera from the closest group, in contrast to 4/22 (18%) from the intermediate distant group, although there was no significant correlation between AMA titer and distance from the hypocenter (P =.07). Of these 28 AMA-positive sera, 11 (39%) were from participants who had already been diagnosed with PBC, and 25 (89%) contained antibodies against at least one component of 2-OADC enzymes by immunoblotting. Therefore, the prevalence of PBC was estimated to be at least 615 cases per million (792 per million women). Our results suggest that the prevalence of PBC in atomic bomb survivors in Nagasaki is higher than that reported for the general population in Japan, and a further survey of the environmental factors, including radiation exposure, that predispose to PBC would be needed for understanding this disease of unknown etiology.
