Abstract
7191 Background: The mechanism of late resistance of NSCLC to gefitinib is unclear. In this study, we assessed clinical factors affecting the late resistance in patients with NSCLC. Methods: Between 2000 and 2004, 197 consecutive patients with NSCLC underwent treatment with gefitinib in our institutions. Of those, 56 patients who had received a prior chemotherapy and continued treatment with gefitinib during at least 6 months were included in this study. The characteristics of these patients were as follows: median age, 62.5 years (range, 28 to 77 years); male/female, 22/34 patients; PS 0/1/2/3/4, 15/31/8/0/2 patients; and adeno/nonadenocarcinoma, 52/4 patients. Thirty-two patients never smoked and 24 were former or current smokers. Nineteen patients underwent surgical resection of NSCLC. Numbers of chemotherapy regimens were one in 31 patients, two in 18, three in 6, four in 1, respectively. Results: Of 56 patients, three achieved a CR and 39 attained a PR, with an overall response rate of 75% (95% CI, 69.2 to 80.8%). The remaining 14 patients had a long SD. At a median follow-up time of 21.6 months (range, 7.7 to 59.7 months), median time to progression was 19.5 months, with progression-free survival rates of 68.5% at 1-year, 33.6% at 2-year, and 21.2% at 3-year, respectively. In a univariate analysis regarding progression-free survival, presences of metastasis to brain (p = 0.008), bone (p = 0.025), liver (p = 0.046), and adrenal (p = 0.008), decreased levels of hemoglobin (p = 0.021) and albumin (p = 0.017), and use of multiple chemotherapy regimens prior to treatment with gefitinib (p = 0.026) were significant factors. In a multivariate analysis using Cox proportional hazard model, presence of brain metastasis was a significant factor clinically affecting the late resistance to gefitinib (hazard ratio, 2.14; 95% CI, 1.10 to 4.17, p = 0.025). In addition, decreased hemoglobin level (p = 0.074) and prior multiple chemotherapy regimens (p = 0.069) were tended to be significant. Conclusions: In patients undergoing treatment with gefitinib, presence of brain metastasis was an important factor indicative of the emergence of late resistance in this study. It is needed to confirm this finding in a large cohort of patients with NSCLC. No significant financial relationships to disclose.

Abstract
AIMS To examine micrometastasis in node-negative hilar bile duct carcinoma (HBDC) using an immunohistochemical method and evaluated the clinical significance. METHODS Four hundred and twenty three regional lymph nodes from 28 patients with node-negative HBDC who had undergone a resection were immunostained with an antibody against cytokeratins eight and 18 (CAM 5.2). RESULTS Lymph node micrometastasis was detected in 11 of the 28 patients and 14 of the 423 lymph nodes. Lymph node micrometastasis was significantly correlated with the pT classification (p=0.03), the histopathological grading (p=0.01) and venous invasion (p=0.05). The 5-year survival rate of the patients with lymph node micrometastasis was 21.8%, as opposed to 66.5% in the patients without micrometastasis. Patients with micrometastasis showed a significantly poorer survival rate than those without micrometastasis (p=0.02). CONCLUSION The results suggest that immunohistochemically detected lymph node micrometastasis has an impact on the outcome in HBDC.

Abstract
BACKGROUND This study aimed to investigate the survival outcome of patients with non-small-cell lung cancer (NSCLC) who had obtained disease stabilisation with gefitinib treatment and to clarify the effect of continued treatment with gefitinib on prognosis. PATIENTS AND METHODS We reviewed the clinical records of 365 Japanese patients with NSCLC who received gefitinib (250 mg/day). RESULTS Of 324 (89%) patients assessable for response, 147 (45%) obtained disease stabilisation and 71 (22%) patients achieved an objective response. Overall survival in patients obtaining disease stabilisation was significantly longer than in patients with progressive disease (median survival time 12.1 versus 4.4 months; P <0.0001). In patients obtaining disease stabilisation, those who continued gefitinib treatment until disease progression tended to have longer overall and progression-free survival compared with those discontinuing gefitinib treatment (1-year survival rate 52.1% versus 36.6%, P = 0.08; 1-year progression-free survival rate 31.8% versus 5.2%, P = 0.001). Multivariate analysis showed discontinuing gefitinib was an independent risk factor for progression-free survival (hazard ratio 1.66; 95% confidence interval 1.07-2.56; P = 0.022) but not for overall survival. CONCLUSIONS Our findings indicate the importance of achieving disease stabilisation with gefitinib treatment and continued gefitinib treatment in Japanese patients with disease stabilisation, although further studies are required to confirm these findings.

Abstract
BACKGROUND Single new agents reportedly produce promising response and survival effects, but platinum-based doublets remain the standard chemotherapy for advanced non-small-cell lung cancer (NSCLC). The aim of this study was to evaluate the effectiveness of platinum for advanced NSCLC by carrying out a meta-analysis of trials that compared platinum-based doublets with single new agent therapy alone. METHODS We carried out a literature search to identify trials, conducted between 1994 and 2003, comparing a doublet of platinum plus a new agent with a new agent alone in previously untreated patients with advanced NSCLC. Outcomes analysed were response, survival and toxicity. RESULTS Eight trials encompassing 2374 patients were identified. Platinum-based doublets produced an approximately two-fold higher overall (complete and partial) response rate than the new agent alone [odds ratio = 2.32; 95% confidence interval (CI)=1.68-3.20]. Platinum-based doublet therapy was also associated with a 13% prolongation of survival (hazard ratio = 0.87; 95% CI = 0.80-0.94, P <0.001). Despite significant increases in the frequencies of various toxic effects in patients receiving platinum-based doublets, no significant difference in treatment-related mortality was observed. CONCLUSION This is the first published meta-analysis demonstrating the importance of combining platinum with single new agents in the treatment of advanced NSCLC.

Abstract
BACKGROUND The aim of this study was to clarify whether the results of surgical treatment of ruptured hepatocellular carcinoma (HCC) are poorer than the results of surgical treatment of non-ruptured HCC. METHODS Out of a total of 224 HCC patients, the 6 patients with ruptured HCC were compared with 15 patients with non-ruptured HCC based on TNM stage IVA and having a Cancer of the Liver Italian Program (CLIP) score of 1 or 2. RESULTS There were no significant differences in clinical and pathological features between the two groups. The 1-year and 3-year overall survival rates were 69.3% and 21.2%, respectively, in the ruptured HCC group and 51.3% and 20.5%, respectively, in the non-ruptured HCC group. The 1-year and 3-year disease-free survival rates were 33.0% and 0%, respectively, in the ruptured HCC group and 38.9% and 15.6%, respectively, in the non-ruptured HCC group. The differences in survival rates between these two groups did not reach statistical significance. CONCLUSION Hepatic resection as definitive treatment after recovery from the initial insult of the rupture of HCC yields results similar to those obtained by surgical treatment of non-ruptured HCC at the same tumor stage and with the same degree of liver damage.

Abstract
The objective of this study was to assess the feasibility and effectiveness of an induction chemoradiotherapy regimen followed by surgery in patients with locally advanced non-small-cell lung cancer (LA-NSCLC). A total of 22 patients with LA-NSCLC were treated with induction chemoradiotherapy consisting of cisplatin (40 mg m−2) and docetaxel (40 mg m−2) given on days 1, 8, 29 and 36 plus concurrent thoracic irradiation at a dose of 40–60 Gy (2 Gy fraction−1 day−1). Surgical resection was performed within 6 weeks after completion of induction therapy. Objective response to the induction therapy was obtained in 16 patients (73%). In all, 20 patients (91%) underwent surgery and complete resection was achieved in 19 patients (86%). Pathological downstaging and pathological complete response were obtained in 14 (64%) and five (23%) patients, respectively. With a median follow-up period of 32 months, the calculated 3-year overall and progression-free survival rates were 66 and 61%, respectively. It is noteworthy that the 3-year overall survival rate in 14 patients achieving pathological downstaging was extremely high (93%). Toxicity was manageable with standard approaches. No treatment-related deaths occurred. This combined modality treatment is feasible and highly effective in patients with LA-NSCLC. The results warrant further large-scale study to confirm the effectiveness of this regimen.

Abstract
The excellent long-term patency rates achieved utilizing the internal thoracic arteries (ITAs) have stimulated a variety of approaches to expand the use of these conduits in coronary revascularization. The ITA divides at the level of the fifth or sixth intercostal space into the superior epigastric and musculophrenic branches. If these terminal branches of the ITA are large and long enough for grafting, they can be used to construct a "Y" anastomosis to the coronary arteries. We experienced 2 patients who underwent multivessel off-pump coronary artery bypass (OPCAB) using these ITA branches. In both patients the bilateral ITAs and the right gastroepiploic artery were taken down using the skeletonization technique as in situ grafts. One patient had 5 grafts including the right ITA terminal branches which were used for the left anterior descending branch (LAD) and diagonal branch. Another patient had 6 grafts including the left ITA terminal branches which were used for the posterolateral branch (PL)1 and PL2. Postoperative angiography revealed widely patent grafts in both patients. We believe that one of the advantages of applying the off-pump technique when the ITA branches are used is that it might be easier to arrange the angle of constructing a natural "Y" configuration compared with conventional coronary artery bypass grafting (CABG). In conclusion, the terminal branches of the ITA, if of suitable size, should be considered for "Y" grafts to diseased coronary arteries when performing complete arterial revascularization with only in situ grafts.

Abstract
To improve the efficacy of fibreoptic bronchoscopy in the diagnosis of peripheral lung cancer, we evaluated the effectiveness of various techniques for obtaining samples for cytological examination. Between January 1984 and December 2000, flexible fibreoptic bronchoscopy under fluoroscopic guidance was performed in 1372 patients with lung cancer having no visible endoscopic findings. Histological examination of specimens obtained by forceps biopsy and cytological examinations on imprints of biopsy specimens, brushing, selective bronchial lavage, curettage, transbronchial needle aspiration, rinse fluids of the forceps, brush, curette, and aspiration needle, and all fluids aspirated during the bronchoscopic examinations were evaluated for diagnostic power. Using these techniques, the overall diagnostic rate with bronchoscopy was 93.4%. The sensitivity of the histological examination was 76.9%; additional imprint cytology increased the sensitivity to 84.8% (P<0.0001), while additional cytology on the rinse fluid of the forceps increased the sensitivity to 83.7% (P<0.0001). The addition of both imprint cytology and cytology on the rinse fluid of the forceps increased the diagnostic rate to 86.2% (P<0.0001). Our results indicate that cytological examinations of the imprints of biopsy samples and the rinse fluids of the forceps and the brush improve the efficacy of fibreoptic bronchoscopy in the diagnosis of peripheral lung cancer.

Abstract
In the present study, we tested whether the pineal organ of ayu (Plecoglossus altivelis), an osmerid teleost close relative of salmonids, harbours a circadian oscillator regulating rhythmic melatonin release using flow-through culture. The pineal organ maintained under light/dark cycles released melatonin in a rhythmic fashion with high levels during the dark phase. A circadian rhythm of melatonin release persisted in constant darkness for at least four cycles. Characteristics of the circadian rhythm (free-running period, phase and amplitude) exhibited small variations among cultures when the data was normalized, indicating that this system is sufficient for the analysis of the circadian rhythm both at qualitative and quantitative levels. Six-hour extension of the light phase from the normal onset time of the dark phase or exposure to constant light for 36 or 48 h before transfer to constant darkness significantly inhibited melatonin release. Phase shifts in the circadian rhythm of melatonin release were also observed. Thus, the ayu pineal organ contains all the three essential components of the circadian system (a circadian clock, the photoreceptor responsible for photic entrainment of the clock, and melatonin generating system as an output pathway). This system should provide a useful model for analysing the physiological and molecular basis of the vertebrate circadian system. In addition, further comparative studies using salmonids and related species including ayu will provide some insight into the evolution of the roles of the pineal organ in the vertebrate circadian system.

Abstract
Recent studies have suggested the superiority of concomitant over sequential administration of chemotherapy and radiotherapy. Docetaxel and cisplatin have demonstrated efficacy in advanced non-small-cell lung cancer (NSCLC). This study evaluated the safety, toxicity, and antitumour activity of docetaxel/cisplatin with concurrent thoracic radiotherapy for patients with locally advanced NSCLC. Patients with locally advanced NSCLC (stage IIIA or IIIB), good performance status, age <or=75 years, and adequate organ function were eligible. Both docetaxel and cisplatin were given on days 1, 8, 29, and 36. Doses of docetaxel/cisplatin (mg m(-2)) in the phase I study portion were escalated as follows: 20/30, 25/30, 30/30, 30/35, 30/40, 35/40, 40/40, and 45/40. Beginning on day 1 of chemotherapy, thoracic radiotherapy was given at a total dose of 60 Gy with 2 Gy per fraction over 6 weeks. In the phase I portion, the maximum tolerated doses (MTD) among 33 patients were docetaxel 45 mg m(-2) and cisplatin 40 mg m(-2). The major dose-limiting toxicity (DLT) was radiation oesophagitis. The recommended doses (RDs) for the phase II study were docetaxel 40 mg m(-2) and cisplatin 40 mg m(-2). A total of 42 patients were entered in the phase II portion. Common toxicities were leukopenia, granulocytopenia, anaemia, and radiation oesophagitis, with frequencies of grade >or=3 toxicities of 71, 60, 24, and 19%, respectively. Toxicity was significant, but manageable according to the dose and schedule modifications. Dose intensities of docetaxel and cisplatin were 86 and 87%, respectively. Radiotherapy was completed without a delay in 67% of 42 patients. The overall response rate was 79% (95% confidence interval (CI), 66-91%). The median survival time was 23.4+ months with an overall survival rate of 76% at 1 year and 54% at 2 years. In conclusion, chemotherapy with cisplatin plus docetaxel given on days 1, 8, 29, and 36 and concurrent thoracic radiotherapy is efficacious and tolerated in patients with locally advanced NSCLC and should be evaluated in a phase III study.

Abstract
With the rapid advance of percutaneous catheter intervention, the direction taken by surgeons is not only to make coronary artery bypass grafting (CABG) less invasive but also to obtain better long-term results by using more arterial conduits. However, off-pump CABG (OPCAB) with only in situ arterial conduits such as the left and right internal thoracic arteries (ITAs) and the right gastroepiploic artery (RGEA) is technically demanding for the surgeon. The purpose of this study was to demonstrate the feasibility and safety of this technique. From January 2002 to December 2002, 57 patients underwent isolated CABG without cardiopulmonary bypass, excluding minimally invasive direct coronary artery bypass (MIDCAB) cases. There were 44 men and 13 women with a mean age of 64.1 years. Most of the patients (95%) underwent postoperative angiography within 1 month after surgery. The mean number of anastomoses was 3.8 +/- 1.4 (range 2-8). One patient suffered from mediastinitis and another from stroke. All patients were discharged from the hospital. Fifty patients (88%) received only in situ grafts for complete revascularization. Forty-one patients received bilateral ITAs and 27 received bilateral ITAs and RGEA. The mean number of anastomoses using bilateral ITAs and RGEA was 4.5 +/- 1.2 (range 3-8). The patency rate was 98%. Complete arterial revascularization with only in situ arterial conduits was associated with minimal operative risk and a high early graft patency rate, even in the off-pump situation. These results indicate that complete revascularization can be achieved in OPCAB with the exclusive use of in situ arterial conduits in patients with diffuse coronary arterial disease.

Abstract
"The mortality rates and causes of death among elderly people aged sixty five and over were compared between China and Japan. The data used for comparison was China's 1990 and Japan's 1990 vital statistics. It appears that the mortality rate in China was higher than Japan. Comparing the causes of death, it was found that the death rates involving cerebrovascular diseases, malignant neoplasms and heart diseases in urban districts of China [were] higher than those in Japan. Also the death rate of people with bronchitis in rural districts was significantly higher in China.... The differences in the medical systems and life styles in China and Japan were suspected as the reasons for the differences of death rates and causes of death...." (SUMMARY IN ENG)
