Abstract
Diagnosis and treatment of bone metastasis requires various types of measures, specialists and caregivers. To provide better diagnosis and treatment, a multidisciplinary team approach is required. The members of this multidisciplinary team include doctors of primary cancers, radiologists, pathologists, orthopaedists, radiotherapists, clinical oncologists, palliative caregivers, rehabilitation doctors, dentists, nurses, pharmacists, physical therapists, occupational therapists, medical social workers, etc. Medical evidence was extracted from published articles describing meta-analyses or randomised controlled trials concerning patients with bone metastases mainly from 2003 to 2013, and a guideline was developed according to the Medical Information Network Distribution Service Handbook for Clinical Practice Guideline Development 2014. Multidisciplinary team meetings are helpful in diagnosis and treatment. Clinical benefits such as physical or psychological palliation obtained using the multidisciplinary team approaches are apparent. We established a guideline describing each specialty field, to improve understanding of the different fields among the specialists, who can further provide appropriate treatment, and to improve patients’ outcomes.

Abstract
The prognostic significance of pack-years smoked (PY) and family history of cancer (FH) was studied using the Cox proportional hazard model in 970 patients with non-small cell lung cancer. PY influenced survival only in women after other variables were adjusted [Hazard ratio (HR): 1.75 (1.45-2.11)]. FH also influenced survival with marginal significance in women with stage I disease [HR: 2.17 (0.89-5.29), p=0.088]. Furthermore, these two factors operated additively in women [HR for patients with both smoking and family histories over those without either: 2.25 (1.18-4.26)], but not in men.

Abstract
BACKGROUND This is a randomized, double-blind, dose-ranging study in patients receiving highly emetogenic chemotherapy (HEC) to evaluate the safety, efficacy, and pharmacokinetics of palonosetron, in combination with dexamethasone. MATERIALS AND METHODS We randomized 233 patients to receive palonosetron as a single i.v. bolus dose of 0.075, 0.25, or 0.75 mg before administration of HEC. Dexamethasone (12-16 mg i.v. on day 1, 8 mg i.v. on day 2, and 4-8 mg i.v. on day 3) was administered for prophylactic antiemesis. Pharmacokinetics of palonosetron was analyzed in 24 patients. RESULTS In this study, all patients were given > or =50 mg/m(2) cisplatin, which was considered to be HEC. No significant differences in complete response (CR: no emesis and no rescue medication) rates were found in the first 24 h between the 0.075-, 0.25-, and 0.75-mg groups (77.6%, 81.8%, and 79.5%, respectively). In the 120-h period of overall observation, CR rates increased in a dose-dependent manner. In the 0.75-mg group, we observed a significantly longer time to treatment failure than in the 0.075-mg group (median time >120 versus 82.0 h, P = 0.038). Palonosetron was tolerated well and did not show any dose-related increase in adverse effects. CONCLUSIONS Palonosetron at doses of 0.25 and 0.75 mg was shown to be effective in preventing chemotherapy-induced nausea and vomiting with high CR rates of patients treated with HEC in Japan. All tested doses of palonosetron were tolerated well.

Abstract
7546 Background: The optimal dose of radiotherapy remains unclear in concurrent chemoradiotherapy for unresectable stage III NSCLC. Methods: Eligible patients (unresectable stage III NSCLC, age ≥ 20 years, PS 0–1, V20 ≤ 30%) received cisplatin (80mg/m2 day 1) and vinorelbine (20mg/m2 days 1 and 8) repeated every 4 weeks for 3–4 cycles. The dose of 3D-CRT was 66 Gy in 33 fractions, 72 Gy in 36 fractions, and 78 Gy in 39 fractions at levels 1–3, respectively. The dose-limiting toxicity (DLT), defined as grade ≥3 esophagitis, pneumonitis, myelitis, dermatitis and heart injury, and early stop of protocol treatment, was evaluated in 6–12 patients at each level. Results: Of the 17, 16 and 24 patients assessed for eligibility, 13 (76%), 12 (75%), and 6 (25%) were enrolled into levels 1–3, respectively, of the study. A total of 26 patients were excluded because of V20 > 30% (n=10), overdose to the esophagus (n=8) and brachial plexus (n=2), comorbidity (n=3), or patient refusal (n=3). There were 26 men and 5 women with a median (range) age of 60 (41–75) years. Of these, 23 (74%) had adenocarcinoma and 20 (65%) had stage IIIA disease. The full planned dose of radiotherapy could be administered in all the patients, and more than 80% of the patients received 3–4 cycles of chemotherapy. Grade 3–4 neutropenia and febrile neutropenia were noted in 24 (77%) and 5 (16%) of the 31 patients, respectively. Grade 4 infection, grade 3 esophagitis and grade 3 pulmonary toxicity were noted in one, two and one patients, respectively. DLT was noted in 17% of the patients at each level. Two (6%) complete and 27 (87%) partial responses were obtained. In a preliminary survival analysis, the median progression-free and overall survivals were determined to be 15.0 months and 37.6 months, respectively. Conclusions: At the level of 78Gy, only 25% of the patients assessed for eligibility were actually eligible. Toxicity was relatively mild up to 78 Gy in this highly selective patient group. Thus, we determined that the recommended dose of 3D-CRT administered concurrently with cisplatin and vinorelbine chemotherapy was 72Gy. [Table: see text]

Abstract
Although global clinical trials for lung cancer can enable the development of new agents efficiently, whether the results of clinical trials performed in one population can be fully extrapolated to another population remains questionable. A comparison of phase III trials for the same drug combinations against lung cancer in different countries shows a great diversity in haematological toxicity. One possible reason for this diversity may be that different ethnic populations may have different physiological capacities for white blood cell production and maturation. In addition, polymorphisms in the promoter and coding regions of drug-metabolising enzymes (e.g., CYP3A4 and UGT1A1) or in transporters (e.g., ABCB1) may vary among different ethnic populations. For example, epidermal growth factor receptor (EGFR) inhibitors are more effective in Asian patients than in patients of other ethnicities, a characteristic that parallels the incidence of EGFR-activating mutations. Interstitial lung disease associated with the administration of gefitinib is also more common among Japanese patients than among patients of other ethnicities. Although research into these differences has just begun, these studies suggest that possible pharmacogenomic and tumour genetic differences associated with individual responses to anticancer agents should be carefully considered when conducting global clinical trials.

Abstract
7061 Background: Amrubicin, a totally synthetic 9-amino-anthracycline, has been shown to have excellent antitumor activity as a single agent against previously untreated extensive-stage SCLC. The objective of this study was to assess the efficacy and safety of amrubicin in patients with refractory or relapsed SCLC. Methods: Patients with histologically or cytologically confirmed SCLC, 20 to 74 years in age, performance status 0–2, with a history of receiving first- or second- line chemotherapy were eligible for the study. Amrubicin (45mg/m2/day) was administered on Days 1–3 every 3 weeks for four to six courses. The primary endpoint was the response rate (RR), and planned sample size for this phase II study was 33 patients (Simon’s two-stage minimax design). Results: From June 2003 to January 2005, 35 patients (26 males/9 females, median age, 64 years) were enrolled, and 34 of these patients were treated with the study drug. Four courses or more were administered in 59% (20/34) of the patients, and dose reduction was required in 52% (15/29) of the patients who had received 2 courses or more. Four complete responses and 14 partial responses were observed among the 34 treated patients, yielding a RR of 53% (95% confidence interval: 35.1%–70.2%). The median survival duration in the patients was 8.8 months, and the 1-year survival rate was 26%. Grade 3/4 leukopenia, neutropenia, and thrombocytopenia were observed in 76%, 97% and 38% of the patients, respectively. Febrile neutoropenia occurred in 12 patients (35%), and one patient died from treatment related pneumonia. Conclusion: Amrubicin (45mg/m2/day) was effective in patients with previously treated advanced SCLC, however, severe hematological toxicities occurred in some patients.

Abstract
7096 Background: G has been shown to exhibit antitumor activity against NSCLC, however, the optimal timing of its administration remains unclear. We conducted a randomized phase II study of CP followed by G or G followed by CP in chemotherapy-naïve advanced NSCLC patients in order to select the candidate arm for a subsequent phase III study. Methods: Chemotherapy-naïve patients with histologically or cytologically confirmed NSCLC, stage IIIB or IV, aged between 20 to74 years, performance status 0–1, were randomized to either Arm A (carboplatin (AUC 6, day 1) plus paclitaxel (200 mg/m2, day 1) every 3 weeks for 4 courses followed by daily G (250 mg/day)) or Arm B (daily G until disease progression followed by CP every 3 weeks for 4 courses). The primary endpoint was overall survival, and the planned sample size for this randomized phase II study was 96 patients (Liu’s selection design for pilot studies on survival). Results: From June 2003 to October 2005, 97 patients were enrolled, and 96 of these patients were treated in this study. Forty-nine patients (males/females: 28/21, median age: 63 years, adeno/non-adeno: 43/6, stageIII/IV: 11/38, smoker/non-smoker: 27/22) were randomized to Arm A and 48 patients (males/females: 28/20, median age: 61 years, adeno/non-adeno: 42/6, stageIII/IV: 11/37, smoker/non-smoker: 28/20) to Arm B. The response rate to CP in Arm A was 32.7% (16/49), and that to G in Arm B was 29.8% (14/47). The median survival was not yet reached, and the 1-year survival rates were 64.5% and 70.5% in Arm A and arm B, respectively. As of January 2006, one patient had died of treatment-related perforative peritonitis and two patients had developed interstitial lung disease. Conclusions: G exhibits similar antitumor activity to CP in chemotherapy-naïve patients with advanced NSCLC. The preliminary survival analysis is proposed to be conducted in April 2006. No significant financial relationships to disclose.

Abstract
7075 Background: Recent studies have shown that EGFR mutations, mainly deletions in exon 19 (DEL) and L858R, are associated with gefitinib sensitivity in patients (pts) with NSCLC. We established a new easy method, using high-resolution melting analysis (HRMA), for detecting DEL and L858R mutations even from small biopsy or cytology samples, and evaluated the significance of EGFR mutations in NSCLC on a larger scale. Methods: Among 364 advanced or recurrent NSCLC pts treated with gefitinib between Jul 2002 and Dec 2004, HRMA was performed in 207 pts from whom specimens were available. DNA extracted from the archival tissue or cytology samples not subjected to microdissection was analyzed to detect DEL and L858R using HR-1 (Idaho Technology), an HRMA device. To validate this method, the results were compared with direct sequencing data obtained from microdissected tumor cells from surgical specimens in 66 pts. Results: Tissue/cytology/both samples were analyzed in 91/77/39 pts. EGFR mutations were detected in 85 (41%; DEL/L858R: 49/36) of the 207 pts. In the comparison with direct sequencing, consistent results were obtained from all of the 66 tissue samples, while false negative results were obtained in 2 of the 28 cytology samples. EGFR mutations were seen more frequently in women (54% vs. 31%; P = .001), never-smokers (53% vs. 32%; P = .002), and pts with adenocarcinoma (44% vs. 11%; P = .007). CR/PR/SD/PD was observed in 2/64/11/8 pts with EGFR mutations and in 0/10/23/89 pts with wild-type EGFR. The response rate (78% vs. 8%), time to progression (median, 9.1 vs. 1.6 months) and overall survival (median, 19.9 vs. 9.1 months) were all significantly superior in pts with EGFR mutations (P < .0001). Minor response and/or long SD (>6 months) was observed more frequently in SD pts with EGFR mutations than in those with wild-type EGFR (91% vs. 26%; P < .001). Among the pts with EGFR mutations, the response rate was significantly higher in the pts with DEL than in those with L858R (86% vs. 67%; P = .037). Conclusions: HRMA is a practical and precise method to detect DEL and L858R mutations. EGFR mutations strongly predict a better response and longer survival in NSCLC pts treated with gefitinib.

Abstract
7165 Background: EGFR mutations are associated with the responses to EGFR-tyrosine kinase inhibitors (TKI) in patients (pts) with adenocarcinoma of the lung. The E746-A750 deletion and L858R substitution mutations are the most common, as previously described. However, their implications in pts treated with conventional chemotherapy are unclear. To evaluate the predictive and prognostic value of the EGFR mutations, we studied pts with adenocarcinoma of the lung treated with conventional chemotherapy. Methods: We reviewed pts with advanced or recurrent chemotherapy naïve adenocarcinoma of the lung who received systemic chemotherapy between January 1999 and July 2001. Deletion in exon 19 and missense mutation (L858R) in exon 21 from small biopsy or cytology samples were analyzed by a high-resolution DNA melting analysis technique. Results: A total of 101 pts, all Japanese, could be analyzed. Patient characteristics were as follows: median age: 62 (37–84) years; female/ male: 39/ 62; never/ former/ current smoker: 47/ 23/ 31; and platinum-based/ non-platinum regimen: 81/ 20 (18 pts received EGFR-TKI later). 43 pts (42.6%) had EGFR somatic mutations; deletion in 24 pts, and a point mutation (L858R) in 19 pts. PR/ SD/ PD/ NE was observed in 11/ 24/ 7/ 1 pts with EGFR mutations and in 13/ 28/ 15/ 2 pts without the mutations, respectively. The response rate was similar (26% vs. 22%, p = .71) in the two subgroups. The median survival duration of the pts with EGFR mutations was 14.9 months (n = 43, including the 11 pts treated with EGFR-TKI later), as compared with 11.0 months (n = 58, including the 7 pts treated with EGFR-TKI later) in the pts without EGFR mutations (p = .09). Another analysis which handle the start of gefitinib administration as a censoring showed similar results (p = .24). Conclusions: EGFR mutations were not good predictors of tumor response to conventional chemotherapy. The overall survival tended to be longer in the pts with EGFR mutations, but prognostic value of these mutations for survival in pts with advanced adenocarcinoma of the lung was not statistically significant. No significant financial relationships to disclose.

Abstract
7087 Background: A promising complete response rate and median survival time were obtained in our previous phase II study of IPE chemotherapy repeated every 4 weeks in patients with ED-SCLC, but the infusion of irinotecan on day 15 was omitted in 77% of patients. Methods: The objective was to evaluate toxicities and antitumor effects of IP and IPE regimens every 3 weeks and to select the arm for subsequent phase III trials. The primary endpoint was overall survival. Previously untreated ED-SCLC patients aged between 20 and 70 years old with a performance status (PS) of 0–2 were randomized to receive either IP (I 60 mg/m2 days 1, 8 and P 60 mg/m2 day 1) or IPE (the same dose of IP and E 50 mg/m2 days 1–3 with G-CSF support) every 3 weeks for 4 cycles. The projected sample size was 110 patients (Liu’s Selection design for pilot studies on survival). Results: From March 2003 to May 2005, 53 patients (43 males/10 females, median age 63) were randomized to IP and 57 patients (48 males/9 females, median age 62) to IPE. Body weight loss and PS were well balanced between the arms. Full cycles were administered in 75% of patients in the IP and in 67% in the IPE arm. Dose reduction was required in 17% of patients in the IP and 28% in the IPE arm. Grade 3–4 neutropenia, anemia and thrombocytopenia were observed in 53%, 34% and 4% of patients in the IP, and 93%, 45%, and 23% of patients in the IPE arm, respectively. Grade 3–4 infection, malaise, anorexia, and diarrhea were noted in 15%, 2%, 0%, and 15% of patients in the IP, and 30%, 11%, 15%, and 24% of patients in the IPE arm, respectively. No treatment related death occurred. Complete and partial responses were noted in 8% and 68% of patients in the IP, and 11% and 75% of patients in the IPE arm, respectively. Conclusion: Toxicity was more severe, but tumor responses seemed better in the IPE arm. The survival analysis will be carried out in April 2006. No significant financial relationships to disclose.

Abstract
7088 Background: There is no standard treatment for relapsed SCLC. Irinotecan and etoposide has been studied in several phase II trials as active agents for relapsed SCLC. We reported the efficacy and tolerability of irinotecan combined with weekly cisplatin and etoposide (PE) in patients (pts) with sensitive relapsed SCLC (Goto, et al. Br J Cancer 2005). Methods: We conducted a phase II study to evaluate the efficacy and toxicity of PE/CPT regimen in pts with refractory relapsed SCLC, who had relapsed within 8 weeks after completion of first-line therapy. Pts must have measurable or assessable disease, age of 75 years or younger, performance status of 0 to 2 (ECOG), and adequate organ function. PE/CPT regimen consisted of cisplatin 25 mg/m2 on day 1 at one-week intervals for 9 weeks (at least 6 weeks), etoposide 60 mg/m2 on days 1–3 on week 1, 3, 5, 7, 9 (at least on week 1, 3, 5), and irinotecan 90 mg/m2 on day 1 on weeks 2, 4, 6, 8 (at least on week 2, 4, 6). After day 1 on week 2, G-CSF was administered on days when cytotoxic drugs were not given. Results: From May 2000 to January 2005, 30 pts were enrolled in this study. Pt characteristics were median age 64 years (range 44–75); 23 male and 7 female; 3 LD and 27 ED. Prior chemotherapy included PE in 13 pts, cisplatin and irinotecan in 7, carboplatin and etoposide in 5, and others in 5. 23 pts (77%) completed 6 or more weeks of chemotherapy. 2 CR and 19 PR were observed and the overall response rate was 70% (95% CI 50.6–85.3%). Grade 3/4 neutropenia, anemia and thrombocytopenia were observed in 60%, 73% and 47%, respectively. Grade 3/4 diarrhea was observed in only 7%. Coclusions: PE/CPT regimen was active and well tolerated for refractory relapsed SCLC. No significant financial relationships to disclose.

Abstract
AIMS Cyclin D1 is a target molecule transcriptionally activated by aberrant beta-catenin in Wnt signalling. Thyroid papillary microcarcinoma (PMC) may be considered a precursor of papillary thyroid cancer (PTC). Ki67 is widely used as a proliferation marker. The aim of this study was to determine whether cyclin D1 overexpression is involved in early thyroid carcinogenesis. METHODS AND RESULTS Thirty-five cases of PMC were examined immunohistochemically, including 11 cases less than 5 mm (PMC < 5) and 24 cases more than 5 mm (PMC > 5), and 18 PTC cases (size 11-15 mm). Cyclin D1 expression was significantly lower in PMC < 5 than in PMC > 5, while there was no significant difference between PMC > 5 and PTC. Statistical analysis revealed significant correlations between cyclin D1 labelling index (LI) and Ki67 LI (P = 0.0272)/cytoplasmic beta-catenin expression (P < 0.001) in PMC and PTC. Four of five PMC > 5 cases with lymph node (LN) metastases displayed a high cyclin D1 LI and strong cytoplasmic beta-catenin expression. CONCLUSIONS Cyclin D1 overexpression and correlation with aberrant beta-catenin expression were demonstrated in PMC. Cyclin D1 expression was significantly associated with tumour size and LN metastases in PMC. Cyclin D1 may be up-regulated at an early stage of thyroid carcinogenesis and promote tumour growth and metastatic potency in PMC through activation of the Wnt/beta-catenin pathway.

Abstract
BACKGROUND The signal transducer and activator of transcription 3 (STAT3) is a key signalling molecule implicated in the regulation of growth and malignant transformation. Constitutive activation of STAT3 is seen in several tumour derived cell lines, and in a wide variety of human malignancies. AIMS To examine the relation between p-STAT3 (activated form of STAT3) expression and clinicopathological factors in human colorectal adenocarcinoma and adenoma. METHODS Immunohistochemical analyses were carried out on tissues from 44 colorectal adenomas and 95 colorectal adenocarcinomas, comprising 18 intramucosal carcinomas and 77 invasive carcinomas. RESULTS Seventy seven of these 139 samples (55.4%) showed immunoreactivity for p-STAT3. Positive staining for p-STAT3 was seen in 69 of the 95 carcinomas. Only eight of the 44 adenomas showed immunopositivity for p-STAT3, resulting in a significant difference between total adenocarcinomas and adenomas (p < 0.001). Among the 95 cases of colorectal adenocarcinoma, p-STAT3 immunoreactivity was significantly correlated with the depth of tumour invasion (p < 0.05), venous invasion (p < 0.05), lymph node metastasis (p < 0.05), and increasing stages of the Dukes' classification (p < 0.01). Expression of p-STAT3 was detected by Western blot analysis in two different cultured human colorectal carcinoma cell lines and six colon carcinoma tissue samples obtained at surgery. CONCLUSION This is the first study to report a significant correlation of p-STAT3 expression with the depth of tumour invasion. These findings suggest that p-STAT3 expression is an important factor related to carcinogenesis and/or tumour invasion of colorectal adenocarcinoma.

Abstract
The proto-oncogene, ets-1, is a transcription factor known to control the expression of a number of genes and has been postulated to play a role in cell growth, differentiation and tumour invasion. We examined 137 cases of breast carcinoma by immunohistochemistry and compared the degree of Ets-1 expression among the different histological types of invasive carcinomas. Ets-1 was not expressed in the normal breast epithelium nor in noninvasive carcinomas. Among the 137 breast carcinoma cases, 104 (83.2%) showed positive staining for the Ets-1 protein. Histologically, invasive ductal carcinomas expressed immunopositivity with intense staining for Ets-1 in the tumour cells. Ets-1 expression correlated with Bloom-Richardson grading in invasive ductal carcinoma (p<0.01). However, there was no correlation between Ets-1 expression and lymph node metastasis, "t" classification or TNM staging. In situ hybridization confirmed the presence of Ets-1 mRNA in breast carcinomas. The expression of Ets-1 mRNA was detected in two of three different kinds of cultured human breast carcinoma cell lines and one of three human breast carcinoma tissues by the reverse transcription polymerase chain reaction method. These findings suggest that ets-1 is overexpressed in ductal cells of the breast that have undergone malignant conversion and that ets-1 is one of the factors associated with tumour growth and histological differentiation of breast carcinomas.
