Abstract P1-14-02: Preoperative docetaxel (T) with or without capecitabine (X) following epirubicin, 5-fluorouracil and cyclophosphamide (FEC) in patients with operable breast cancer (OOTR N003): Results of comparative study and predictive marker analysis

Objective: This preoperative study aimed to evaluate the efficacy of 4 cycles of TX compared with 4 cycles of T, following 4 cycles of FEC in operable breast cancer patients.

Methods: Women with operable breast cancer (T1C-3N0M0/T1-3N1M0) were randomly assigned to receive either T (75 mg/m2, q3) plus X (825 mg/m2 bid, days 1 to 14) or T alone (75 mg/m2, q3) after completion of FEC (5-fluorouracil 500 mg/m2, epirubicin 100 mg/m2, cyclophosphamide 500 mg/m2, q3). Patients who had disease progression on FEC were excluded from randomization. The primary endpoint was pathological complete response (pCR). Predictive factor analysis was conducted using clinicopathological markers such as hormone receptors, Ki67 labeling index (Ki67LI) and thymidine phosphorylase (TP).

Results: From November 2005 to October 2009, 504 patients were enrolled and 239 and 238 patients were assigned to TX and T group, respectively (median age 49 years, median tumor size 3.5 cm and node positive rate 56%). Treatment discontinuation was observed in 22% of TX group and 5% in T group (p < 0.0001). The major reasons for discontinuation were toxicity, refusal/ consent withdrawal and several others. No significant difference in pCR rate was shown between the two groups (TX 23% and T 24%, p = 0.748). Neither clinical response nor surgical outcome differed between TX and T. The pCR rate in patients who had therapy discontinuation or dose-reduction on TX was 23%, whereas pCR rate in those on T was 11%. A subpopulation treatment effect pattern plots method indicated a trend that TX may improve the pCR rate in patients having a middle range of pretreatment Ki67LI, such as 10%–20%. In the median follow-up time of 3.7 years, disease-free survival (DFS) was not different between TX and T (3-year DFS: 92% in TX and 91% in T; hazard ratio 0.907, 95%CI 0.528–1.557, p = 0.723). The frequency of major grade 3 or greater adverse events of TX and T were leukopenia, 36% and 34%, febrile neutropenia 8% and 5%, and hand-foot syndrome 15% and 2%, respectively.

According to the analysis for evaluating predictive values of biomarkers, a multivariate logistic regression analysis showed that HER2 (+/−: odds ratio 4.107, p < 0.0001), Ki67LI (continuous variables: 1.029, p = 0.003), hormone receptor status (+/−: 0.457, p = 0.009), stroma TP status (0.523, p = 0.02) and grade (1/3: 0.387, 2/3: 0.532, p = 0.047) had statistical significant values for predicting pCR. A multiple Cox model in landmark analysis showed that tumor size (p < 0.0001), cancer cell TP status (p = 0.005), pCR and posttreatment Ki67LI (p = 0.016), and age (p = 0.049) were associated with DFS significantly.

Conclusions: Addition of X to T showed no superiority to T alone following FEC in neoadjuvant treatment of these patients with operable breast cancer. Treatment discontinuation rate was significantly higher in TX than T group, however the pCR rate in patients in TX group who required treatment discontinuation or dose-reduction was similar to that in patients who completed as scheduled, which was different from T group. Determination of pre-/ post-treatment Ki67LI looks useful for predicting pCR and DFS.

Radiographic and pathological analysis of small lung adenocarcinoma using the new IASLC classification

AIM

To analyse the correlation between computed tomography (CT) findings of small lung adenocarcinomas and the International Association for the Study of Lung Cancer/American Thoracic Society/European Respiratory Society Classification of Lung Adenocarcinoma.

MATERIALS AND METHODS

A retrospective review of 300 lung adenocarcinoma lesions (size ≤20 mm) after surgical resection in 295 consecutive patients was performed. Tumours were defined as air-containing type if the ratio of the maximum dimension of the tumour on mediastinal windows to the maximum dimension of the tumour on lung windows was ≤50%, and as solid-density type if the ratio was >50%. The incidence between CT findings (air bronchogram, vascular involvement, pleural tags, notches, and spiculation) and pathological findings were investigated.

RESULTS

Of the 142 air-containing lesions, 114 were adenocarcinoma in situ (AIS), 28 were minimally invasive adenocarcinoma (MIA), and none of the lesions were invasive adenocarcinoma. Of the 158 solid-density lesions, 30 were AIS, 24 were MIA, and 104 were invasive adenocarcinoma. Notches and pleural tags were commonly observed in cases of invasive adenocarcinoma (p < 0.05).

CONCLUSIONS

In the air-containing type of small lung adenocarcinomas, AIS and MIA were observed but no cases of invasive adenocarcinoma were found. The presence of notches and pleural tags were a significant factor in invasive adenocarcinoma.

Density fluctuation measurements using beam emission spectroscopy on Heliotron J

This paper describes the measurement of the density fluctuation using beam emission spectroscopy in Heliotron J, having the non-symmetrical helical-magnetic-axis configuration. In order to optimize the sightlines, the numerical calculations are carried out to estimate the spatial resolution and the observation location. When a tangential neutral beam is used as diagnostic one, suitable sightlines from the newly installed diagnostic port are selected whose spatial resolution Δρ is less than ± 0.07 over the entire plasma region. Modification of the interference filter and the detection systems enables us to measure the radial profile of the density fluctuation. Each of the three coherent modes due to the fast-ion-driven magnetohydrodynamic instabilities has different radial structure of the density fluctuation.

Assessment of the Plasma/Serum IgG Test to Screen for Periodontitis

Chronic periodontitis is a silent infectious disease prevalent worldwide and affects lifestyle-related diseases. Therefore, efficient screening of patients is essential for general health. This study was performed to evaluate prospectively the diagnostic utility of a blood IgG antibody titer test against periodontal pathogens. Oral examination was performed, and IgG titers against periodontal pathogens were measured by ELISA in 1,387 individuals. The cut-off value of the IgG titer was determined in receiver operating characteristic curve analysis, and changes in periodontal clinical parameters and IgG titers by periodontal treatment were evaluated. The relationships between IgG titers and severity of periodontitis were analyzed. The best cut-off value of IgG titer against Porphyromonas gingivalis for screening periodontitis was 1.682. Both clinical parameters and IgG titers decreased significantly under periodontal treatment. IgG titers of periodontitis patients were significantly higher than those of healthy controls, especially in those with sites of probing pocket depth over 4 mm. Multiplied cut-off values were useful to select patients with severe periodontitis. A blood IgG antibody titer test for Porphyromonas gingivalis is useful to screen hitherto chronic periodontitis patients (ClinicalTrials.gov number NCT01658475).

Perineural spread of adenoid cystic carcinoma in the oral and maxillofacial regions: evaluation with contrast-enhanced CT and MRI

OBJECTIVES

The objective of this study was to compare the accuracy of contrast-enhanced CT (CECT) and contrast-enhanced MRI (CEMRI) in the detection of perineural spread (PNS) of adenoid cystic carcinoma (ACC) in the oral and maxillofacial regions.

METHODS

This study consisted of 13 ACCs from 13 patients, all of which were histopathologically diagnosed. Both CECT and CEMRI were performed in all patients before the treatment. The images of each patient were retrospectively evaluated for the detection of PNS. The definitions of PNS included abnormal density/signal intensity, contrast enhancement or widening of the pterygopalatine fossa, palatine foramen, incisive canal, mandibular foramen and mandibular canal, and enlargement or excessive contrast enhancement of a nerve.

RESULTS

11 out of 13 cases were proven to exhibit PNS histopathologically. 8 of the 11 cases for which PNS was histopathologically proven exhibited PNS on MR images. Six of the eight cases for which PNS was exhibited on MR images also exhibited PNS on CT images. The sensitivity, specificity and accuracy for the detection of PNS were 55%, 100% and 62% on CT images and 73%, 100% and 77% on MR images, respectively. Although the accuracy of PNS on MR images was slightly superior to that on CT images, there were no statistically significant differences between the detection of PNS on CT images and on MR images.

CONCLUSIONS

CT and MR images are equally useful for the detection of PNS of ACC in the oral and maxillofacial regions.

Adiponectin regulates functions of gingival fibroblasts and periodontal ligament cells

BACKGROUND AND OBJECTIVE

Adiponectin is a cytokine constitutively produced by adipocytes and exhibits multiple biological functions by targeting various cell types. However, the effects of adiponectin on primary gingival fibroblasts and periodontal ligament cells are still unexplored. Therefore, we investigated the effects of adiponectin on gingival fibroblasts and periodontal ligament cells.

MATERIAL AND METHODS

The expression of adiponectin receptors (AdipoR1 and AdipoR2) on human gingival fibroblasts (HGFs), mouse gingival fibroblasts (MGFs) and human periodontal ligament (HPDL) cells was examined using RT-PCR and western blotting. HGFs and MGFs were stimulated with interleukin (IL)-1β in the presence or absence of adiponectin, and the expression of IL-6 and IL-8 at both mRNA and protein levels was measured by real-time PCR and ELISA, respectively. Furthermore, small interfering RNAs (siRNAs) in MGFs were used to knock down the expression of mouse AdipoR1 and AdipoR2. The effects of adiponectin on the expression of alkaline phosphatase (ALP) and runt-related transcription factor 2 (Runx2) genes were evaluated by real-time PCR. Mineralized nodule formation of adiponectin-treated HPDL cells was revealed by Alizarin Red staining.

RESULTS

AdipoR1 and AdipoR2 were expressed constitutively in HGFs, MGFs and HPDL cells. Adiponectin decreased the expression of IL-6 and IL-8 in IL-1β-stimulated HGFs and MGFs. AdipoR1 siRNA in MGFs revealed that the effect of adiponectin on reduction of IL-6 expression was potentially mediated via AdipoR1. Adiponectin-treated HPDL cells promoted the expression of ALP and Runx2 mRNAs and up-regulated ALP activity. Furthermore, adiponectin enhanced mineralized nodule formation of HPDL cells.

CONCLUSION

Our observations demonstrate that adiponectin exerts anti-inflammatory effects on HGFs and MGFs, and promotes the activities of osteoblastogenesis of HPDL cells. We conclude that adiponectin has potent beneficial functions to maintain the homeostasis of periodontal health, improve periodontal lesions, and contribute to wound healing and tissue regeneration.

Association between dietary folate intake and clinical outcome in head and neck squamous cell carcinoma

BACKGROUND

The association between dietary folate intake, two polymorphisms in methylenetetrahydrofolate reductase (MTHFR) and thymidylate synthase (TYMS), and survival in head and neck squamous cell carcinoma (HNSCC) patients is not clarified.

PATIENTS AND METHODS

We conducted a retrospective cohort study of 437 HNSCC patients treated at Aichi Cancer Center. We evaluated the survival impact of pretreatment dietary folate intake, which was estimated using a food-frequency questionnaire, and two polymorphisms, MTHFR C677T and a 6-bp insertion/deletion in the 3'-untranslated region of TYMS, using multivariate proportional hazard models.

RESULTS

Patients with high folate intake (≥320 μg/day; n=144) had significantly higher survival than patients with low or medium folate intake (<320 μg/day; n=278; 79.1% versus 68.2%, respectively, P=0.020). This association was consistent with multivariate analyses adjusted for established prognostic factors (hazard ratio 0.56; 95% confidence interval 0.37-0.84). MTHFR and TYMS polymorphisms did not show significant association with survival, although the TYMS 6-bp insertion allele showed potential association with a reduced risk of death. Notably, no significant interaction was observed between folate intake and the two examined polymorphisms.

CONCLUSIONS

High pretreatment dietary folate intake was identified as an independent prognostic factor associated with improved clinical outcomes in HNSCC patients. Further study is warranted.

Possible involvement of CD14+ CD16+ monocyte lineage cells in the epidermal damage of Stevens-Johnson syndrome and toxic epidermal necrolysis

BACKGROUND

Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are characterized by keratinocyte apoptosis and necrosis, resulting in epidermal detachment. Although monocytes abundantly infiltrate the epidermis in SJS/TEN skin lesions, the properties and functions of these cells have not been fully examined.

OBJECTIVES

To determine the properties of monocytes infiltrating into the epidermis in SJS/TEN.

METHODS

Immunostaining of skin sections was performed to examine the membrane markers of monocytes infiltrating into skin lesions.

RESULTS

Immunostaining of cryosections from 11 SJS/TEN skin lesions revealed numerous CD14+ monocytes located along the dermoepidermal junction and throughout the epidermis. The cells coexpressed CD16, CD11c and HLA-DR. CD14+ CD16+ cells were identified in very early lesions without epidermal damage, suggesting that their infiltration is a cause, rather than a result, of epidermal damage. Moreover, these cells expressed CD80, CD86 and CD137 ligand, indicative of their ability to facilitate the proliferation and cytotoxicity of CD8+ T cells. CD16+ cells infiltrating the epidermis and detected at the dermoepidermal junction were immunostained and counted in paraffin-embedded skin sections obtained from 47 patients with drug rash manifested as TEN, SJS, maculopapular-type rash or erythema multiform-type rash. The number of CD16+ monocytes infiltrating the epidermis increased significantly, depending on the grade of epidermal damage.

CONCLUSIONS

These findings suggest that the appearance of CD14+ CD16+ cells of monocyte lineage plays an important role in the epidermal damage associated with SJS/TEN, most probably by enhancing the cytotoxicity of CD8+ T cells.

Calcifying cystic odontogenic tumour: CT imaging

OBJECTIVES

Calcifying cystic odontogenic tumour (CCOT) is a rare disorder of the jaw. A comparison between conventional radiographs and CT images in CCOTs has not been reported. The purposes of this study were to analyse conventional radiographs and CT images of CCOTs, establish CT images of CCOTs and assess the utility of CT in the diagnosis of CCOTs.

METHODS

Nine patients with a histopathologically confirmed CCOT who had both conventional radiographs and CT images were enrolled.

RESULTS

CT was superior to conventional radiographs in detecting buccolingual expansion, odontomas and radio-opaque bodies.

CONCLUSION

The characteristic CT appearances of CCOT were that radio-opaque bodies were typically located in the periphery of the lesion and the shape of radio-opaque bodies was linear and/or spotted. CT was useful in diagnosing a CCOT.

Neurinoma of the greater superficial petrosal nerve developed acute facial palsy: case report and review of the literature

The authors report on a patient with a greater superficial petrosal nerve neurinoma. The patient developed severe acute facial palsy and the palsy improved soon after removal of the tumor. We review of the literature and describe its rarity and surgical treatment with regard to other facial nerve neurinomas originating from the main trunk of the facial nerve.

Hepatocyte growth factor incorporated into herpes simplex virus vector accelerates facial nerve regeneration after crush injury

Hepatocyte growth factor (HGF) promotes regeneration of the central nervous system, but its effects on the peripheral nervous system remain unclear. This study was conducted to elucidate the effect of HGF on regeneration of the murine facial nerve after crush injury. To do so, a replication-defective herpes simplex virus vector that incorporated HGF was prepared (HSV-HGF). The main trunk of the facial nerve was compressed by mosquito hemostats, and HSV-HGF, control vector or medium was then applied to the compressed nerve. We found that mice in the HGF group required significantly fewer days for complete recovery from nerve compression. Furthermore, the amplitude of the evoked buccinator muscle compound action potential increased following HSV-HGF application. HGF expression in and around the compressed nerve was demonstrated by enzyme-linked immunoassay and immunohistochemistry. In addition, HSV-HGF introduction around the damaged nerve significantly accelerated recovery of function of the facial nerve. These data suggest a possible role of HGF in promoting facial nerve regeneration after nerve damage. Furthermore, this viral delivery method may be applied clinically for many types of severe facial palsy during facial nerve decompression surgery.

Reductive alteration of the regulatory function of the CD4(+)CD25(+) T cell fraction in silicosis patients

Causal links have been documented between silica and rheumatoid arthritis, lupus erythematosus, systemic sclerosis and glomerulonephritis. Two different effects of silica have been suggested, an enhanced inflammatory response in the pulmonary region (e.g. activation of alveolar macrophages) and dysregulation of autoimmunity. Based on our previous reports showing in vitro activation of peripheral T cells by silica and reduced regulatory function of the peripheral CD4(+)CD25(+) fraction in which FoxP(3)+ regulatory T cells (Treg) are located, reconstitution of the CD4(+)CD25(+) fraction in silicosis patients (SILs) was investigated. Since T cells in peripheral CD4(+)CD25(+) and CD4(+)CD25(-) (effector T cells; Teff) fractions from SILs showed higher expression of pd-1 (a marker gene for T cell activation) in comparison to that of healthy donors (HDs), chronic T cell activation was considered to have occurred in SILs. In this study, a higher expression of the CD95/Fas molecule in Treg was recorded from silicosis patients (SILs) compared to healthy donors (HDs), and excess loss of FoxP3(+) Treg in freshly isolated peripheral blood mononuclear cells (PBMCs) from SILs relative to HDs was demonstrated when these cells were cultured with silica ex vivo, whereas CD25(+) cells were not reduced due to contamination of activated Teff in the CD4(+)CD25(+) fraction. The activation of both Teff and Treg results in reconstitution of the peripheral CD4(+)CD25(+) fraction, loss of Treg and contamination of activated Teff, resulting in reduction of the number and function of Treg. These results contribute to our understanding of the development of autoimmune diseases found in SILs.

Feasibility study of postoperative management based on ERAS of patients with gastrectomy

127

Background: Although the usefulness of the postoperative management based on Enhanced Recovery After Surgery (ERAS) program of patents with colectomy is shown, there are a few papers concerning ERAS program for gastric cancer patients. The aim of the present study was to examined whether a new postoperative management based on ERAS was feasible for pts with gastrectomy.

Methods: From September 2009 to April 2010, we have adopted the new clinical pathway (CP) based on ERAS and oral rehydration therapy (ORT) for 30 consecutive gastric cancer patients who underwent curative gastrectomy. These pts began a oral rehydration solution (ORS) on the first postoperative day, and after the volume of ORS got 1,000 ml, we stopped intravenous transfusion. The incidence of adverse events, postoperative pt's activity score, which pt's daily activity was evaluated with, and total infusion volume of these pts were compared with 30 pts with the previous CP that were enrolled as a control group.

Results: There were no significant differences in the clinical and operative factors between the two groups. The post operative patient's activity score of ERAS group was significantly higher up to 7th postoperative day (POD). Total infusion volume was significantly little besides, in most cases, infusion therapy was substituted for ORT with OS-1 within 2 POD. There was no difference in the hospitalized days, and the incidence of adverse events were statistically no significance between two groups.

Conclusions: Our CP based on ERAS and ORT is feasible for patients with gastrectomy.

No significant financial relationships to disclose.

Abstract P2-02-01: Characterization of the Breast Lesions by Biexponential Signal Attenuation Analysis of Diffusion-Weighted Magnetic Resonance Images

Purpose: Signal attenuation of diffusion-weighted magnetic resonance images (DWI) in vivo with high b-values is sometimes non-linear when plotted with a semilogarithmic function, but it fits well with the biexponential equation, Sb/S0=f1exp(bD1) + (1-f1)(bD2). Others have indicated that the fast and slow component fractions (f1, 1-f1) of the apparent diffusion coefficients (D1, D2) can be derived by biexponential fitting, and that these fractions correspond to actual diffusion components in the extra-and intracellular space. Here, we investigated the clinical value of DWI for breast screening by performing multi b-factor DWI on healthy volunteers and patients. We then analyzed signals by fitting them with the biexponential equation and compared the fitting parameters of breast lesions.

Patients and methods: This study was approved by our center's institutional review board and all patients and volunteers gave their informed consent. We analyzed data from eight healthy females (controls) and 80 female patients with a total of 100 breast tumors (42 benign and 58 malignant). We performed DWI using 12 and 6 b-values for the controls and patients up to a maximum b-value of 3500 sec/mm2.

Results: We identified the DWI signal attenuation features of the normal mammary gland, and of benign and malignant tumors [Figure1]. The DWI signal attenuation was similar between some proliferative benign tumors and malignancies. A comparison of the parameters derived from biexponential fitting revealed a significant difference in f1 between noninvasive and invasive ductal carcinoma [Figure 2]. Conclusion: The biexponential fitting parameters might reflect the features of tumor cellularity. Thus, to distinguish malignant from benign breast tumors only by DWI is difficult due to the pathological diagnosis that rather emphasizes cell configuration or shape rather than cellularity. Nevertheless, our findings will help to understand why malignant tumors present as high signal intensity in DWI.

FGF-2 stimulates periodontal regeneration: results of a multi-center randomized clinical trial

The efficacy of the local application of recombinant human fibroblast growth factor-2 (FGF-2) in periodontal regeneration has been investigated. In this study, a randomized, double-blind, placebo-controlled clinical trial was conducted in 253 adult patients with periodontitis. Modified Widman periodontal surgery was performed, during which 200 µL of the investigational formulation containing 0% (vehicle alone), 0.2%, 0.3%, or 0.4% FGF-2 was administered to 2- or 3-walled vertical bone defects. Each dose of FGF-2 showed significant superiority over vehicle alone (p < 0.01) for the percentage of bone fill at 36 wks after administration, and the percentage peaked in the 0.3% FGF-2 group. No significant differences among groups were observed in clinical attachment regained, scoring approximately 2 mm. No clinical safety problems, including an abnormal increase in alveolar bone or ankylosis, were identified. These results strongly suggest that topical application of FGF-2 can be efficacious in the regeneration of human periodontal tissue that has been destroyed by periodontitis.

The role of inhibitor of DNA-binding (Id1) in hyperproliferation of keratinocytes: the pathological basis for middle ear cholesteatoma from chronic otitis media

OBJECTIVES

A hallmark of cholesteatoma is hyperproliferation of keratinocytes with abundant production of keratins in the middle ear under chronic inflammatory conditions. However, little is known about the driving force of cellular proliferation and keratin production of cholesteatomal matrix. The purpose of this study was to investigate the cellular proliferation and keratin production of keratinocytes under the influence of Id1, a candidate transcription factor to cell proliferation.

MATERIALS AND METHODS

Keratinocytes were transfected with Id1 and the responses of keratinocytes to Id1 were studied by using cellular and molecular biologic methods.

RESULTS

Id1 positively contributed to the cell cycle progression and negatively to the p16(Ink4a) downregulation via the nuclear factor-kappa B (NF-κB)/cyclin D1 pathway. Id1 significantly increased the promoter activity of NF-κB which, in turn, up-regulated the expression of cyclin D1 and keratin 10 in keratinocytes. Specific NF-κB inhibitors (pyrrolidine dithiocarbamate, PDTC), or dominant-negative inhibitor (I kappa B alpha mutant, IκBαM) abrogated the Id1-induced cell proliferation and keratin 10 production whereas p65, a subunit of the NF-κB heterodimer and an enhancer of the NF-κB activity, strengthened the Id1-induced cell proliferation and keratin 10 production.

CONCLUSIONS

Id1 contributed to hyperproliferation of keratinocytes via enhancement of cell cycle progression, removal of cell cycle inhibition, and simultaneously increased keratin production.

Phase II study of nedaplatin and irinotecan with concurrent thoracic radiotherapy in patients with locally advanced non-small-cell lung cancer

Background:

Current international guidelines recommend the use of platinum-based chemotherapy with thoracic radiotherapy (TRT) for patients with locally advanced non-small-cell lung cancer (NSCLC).

Methods:

Patients with unresectable stage IIIA or IIIB NSCLC were treated with nedaplatin (NP) at 50 mg m⁻² and irinotecan (CPT) at 60 mg m⁻² on days 1 and 8 every 4 weeks for two to four cycles with concurrent TRT (2 Gy per day, total 60 Gy).

Results:

All 35 patients were able to receive a total of 60 Gy. Adverse effects and events in chemotherapy with TRT were grade 3 or 4 anaemia, neutropenia and thrombocytopenia, which occurred in 3.0%, 32.8% and 6.0% of patients, respectively. There was no grade 3 pneumonitis or oesophagitis. Adverse effects and events in chemotherapy alone were mild. There was no treatment-related death. An overall response rate was 94.3%. The median progression-free and overall survivals were 13.0 and 36.0 months, respectively. The 5-year disease-free and overall survival rates were 25.7% and 40.0%, respectively.

Conclusion:

NP and CPT treatment with concurrent TRT is effective and safe for patients with unresectable, locally advanced NSCLC.

Application of beam emission spectroscopy to NBI plasmas of Heliotron J

This paper describes the application of the beam emission spectroscopy (BES) to Heliotron J, having the nonsymmetrical helical-magnetic-axis configuration. The spectral and spatial profile of the beam emission has been estimated by the numerical calculation taking the collisional excitation processes between plasmas (electrons/ions) and beam atoms. Two sets of the sightlines with good spatial resolution are presented. One is the optimized viewing chords which have 20 sightlines and observe the whole plasma region with the spatial resolution Δρ less than ±0.055 using the newly designed viewing port. The other is 15 sightlines from the present viewing port of Heliotron J for the preliminary measurement to discuss the feasibility of the density fluctuation measurement by BES. The beam emission has been measured by a monochromator with a CCD camera. A good consistency has been obtained between the spectral profiles of the beam emission measured by the monochromator and the beam emission spectrum deduced by the model calculation. An avalanche photodiode with an interference filter system was also used to evaluate the signal-to-noise (S/N) ratio of the beam emission in the present experimental setup. The modification of the optical system is being planned to improve the S/N ratio, which will enable us to estimate the density fluctuation in Heliotron J.
