Abstract
A 57-year-old woman with von Recklinghausen's disease presented with epigastralgia. Gastroduodenoscopy revealed swelling of the ampulla of Vater in the ventral and caudal direction, forming a hard, elastic mass. She was diagnosed with a tumor of the ampulla of Vater, and a subtotal stomach-preserving pancreaticoduodenectomy and D2 lymph node dissection were performed. The isolated specimen showed an intra-ampullary tumor of the ampulla of Vater and a submucosal tumor in the descending duodenum, which were diagnosed as a somatostatin-producing neuroendocrine tumor and gastrointestinal stromal tumor, respectively, on pathological examination. We believe that the neuroendocrine tumor of the ampulla of Vater and gastrointestinal stromal tumor of the duodenum are common gastrointestinal lesions in von Recklinghausen's disease.

Abstract
BACKGROUND Antibody-dependent-mediated cytotoxicity (ADCC) is one of the modes of action for trastuzumab. Recent data have suggested that fragment C γ receptor (FcγR) polymorphisms have an effect on ADCC. This prospective phase II trial aimed to evaluate whether these polymorphisms are associated with clinical efficacies in patients who received trastuzumab. PATIENTS AND METHODS Patients in a neoadjuvant (N) setting received Adriamycin and cyclophosphamide followed by weekly paclitaxel/trastuzumab. Patients in a metastatic (M) setting received single trastuzumab until progression. In total, 384 distinct single nucleotide polymorphisms of different FcγR, HER2, and fucosyltransferase loci were assessed. RESULTS Fifteen operable and 35 metastatic HER2-positive breast cancer patients were enrolled in each of the N and M settings, respectively. The FcγR2A-131 H/H genotype was significantly correlated with the pathologically documented response (pathological response) (P = 0.015) and the objective response (P = 0.043). The FcγR3A-158 V/V genotype was not correlated with the pathological response, but exhibited a tendency to be correlated with the objective response. Patients with the FcγR2A-131 H/H genotype had significantly longer progression-free survival in the M setting (P = 0.034). CONCLUSION The FcγR2A-131 H/H polymorphism predicted the pathological response to trastuzumab-based neoadjuvant chemotherapy in early-stage breast cancer, and the objective response to trastuzumab in metastatic breast cancer.

Abstract
Background: Although a pathologic complete response (pCR) after neoadjuvant chemotherapy is associated with favourable outcomes, a small proportion of patients with pCR have recurrence. This study was designed to identify factors predictive of recurrence in patients with pCR. Methods: A total of 449 breast cancer patients received neoadjuvant chemotherapy, and 88 evaluable patients had a pCR, defined as no evidence of invasive carcinoma in the breast at surgery. The clinical stage was II in 61 patients (69%), III in 27 (31%). All patients received taxanes and 92% received anthracyclines. Among 43 patients with HER2-positive tumours, 27 received trastuzumab. Cox regression analyses were performed to identify predictors of recurrence. Results: Median follow-up was 46.0 months. There were 12 recurrences, including 8 distant metastases. The rate of locoregional recurrence was 10.4% after breast-conserving surgery, as compared with 2.5% after mastectomy. Multivariate analysis revealed that axillary metastases (hazard ratio (HR), 13.6; P<0.0001) and HER2-positive disease (HR, 5.0; P<0.019) were significant predictors of recurrence. Five of six patients with both factors had recurrence. Inclusion of trastuzumab was not an independent predictor among patients with HER2-positive breast cancer. Conclusion: Our study results suggest that HER2 status and axillary metastases are independent predictors of recurrence in patients with pCR.

Abstract
BACKGROUND The aim of this study was to develop a prediction model of progressive disease (PD) in breast cancer patients without measurable disease in first-line chemotherapy. METHODS We developed a model to predict PD using carcinoembryonic antigen (CEA) and carbohydrate antigen (CA) 15-3 in metastatic breast cancer patients who were enrolled in a phase III trial. The model was determined using the area under the receiver operating characteristic curve (AUC) calculated by the bootstrap method as internal validation. We verified the model for those who received first-line chemotherapy in a clinical setting as external validation. We categorized patients without measurable disease into PD and non-PD groups and compared the time to progression (TTP). RESULTS The model consisted of percent changes in CEA and CA 15-3 levels from second to third chemotherapy course and baseline abnormality of them. The AUC after external validation was 0.90. Patients without measurable disease were categorized into PD (N = 10) and non-PD groups (N = 53) by the model. The difference in TTP between the two groups was statistically significant (hazard ratio, 0.437; P = 0.021). CONCLUSION The model may be useful to determine PD in metastatic breast cancer patients without measurable disease.

Abstract
BACKGROUND The objective of this study was to evaluate the age-based enrollment of cancer patients into registration trials of new drug applications or expanding the indications for use. MATERIALS AND METHODS The data from 234 registration trials in Japan and overseas of 43 drugs, which were reviewed by the Pharmaceuticals and Medical Devices Agency and approved by the Ministry of Health, Labour and Welfare in Japan between 1999 and 2008, were retrospectively analyzed according to the age distribution of enrolled patients. The age distribution of the Japanese cancer population was derived from Cancer Statistics in Japan 2003 and Annual Report on Health, Labour and Welfare 2003-2004. RESULTS In the Japanese cancer population, the estimated median age of cancer patients is 70 years, and 66% of cancer patients are aged 65 years or more. The estimated median age of cancer patients in all registration trials conducted in Japan was 59 years, whereas it was 55 years in the registration trials conducted overseas. The proportion of patients aged 65 years or more enrolled in registration trials conducted in Japan was 35%; this number was 28% in registration trials conducted overseas. CONCLUSION Elderly patients are underrepresented in oncology registration trials in Japan.

Abstract
1100 Background: The antibody dependent cell mediated cytotoxicity (ADCC) affects an efficacy of Immunoglobulin G1 antibody, including trastuzumab which is a humanized anti-HER-2 monoclonal antibody, through fragment C receptor (FcγR) polymorphisms. One report suggested that allotype of two kinds of FcγR single nucleotide polymorphisms (SNPs) are associated with clinical outcome of patients (pts) with metastatic breast cancer (BC) who received combination trastuzumab with taxane. Ethnic difference was reported in frequency of these SNPs between Western and Asian pts. The objective of this prospective study was to evaluate whether these SNPs are associated with pathological complete response (pCR) in neoadjuvant (N) setting with pts who received trastuzumab based chemotherapy, and objective response (OR) in metastatic (M) setting in pts who received single trastuzumab. Methods: Eligible criteria include HER-2 positive BC, chemotherapy-naïve, measurable disease, PS 0–2 and adequate organ functions. Pts in N setting received standard FEC (5-fluorouracil/epirubicin/cyclophosphamide q3w for 4cycles followed by weekly paclitaxel/trastuzumab for 12 weeks. Pts in M setting received single trastuzumab q1w until progression. 384 SNPs of different FcγR loci were assessed from genomic DNA extracted from peripheral blood by GOLDEGATE beads array (illumina Co.). Results: Nineteen operable and 36 metastatic HER-2 positive BC pts have been enrolled in each N and M setting, respectively. pCR in N setting was 26.3%, and OR in M setting was 22.2%. The frequencies of FcγRIIa131 genotypes were H/H 43%, H/R 49%, R/R 8%, and that of FcγRIIIa158 were V/V 43%, V/F 47%, F/F 10%, respectively. 131H/H genotype was significantly correlated with pCR (p = 0.0034) and OR (p = 0.037). 158V/V genotype had a tendency to be correlated with pCR (p = 0.067) and was significantly correlated with OR (p = 0.037). The median PFS was 8.9 months for pts with 131H/H and 3.8 months for R carriers (H/R or R/R). Conclusions: Our data for the first time suggest that these two SNPs predict pCR to trastuzumab based chemotherapy in N setting, and OR to single trastuzumab in M setting. No significant financial relationships to disclose.

Abstract
5588 Background: Second-line chemotherapy after the front-line platinum based regimens including concurrent chemoradiation (CCRT) has not been established for patients with advanced or recurrent cervical cancer. Platinum based regimens are often selected, but the predictive and prognostic factors of secondary platinum therapy are unclear. We therefore evaluated the relative influence of platinum free interval ( PFI ) between the completion of front-line regimen and the institution of second-line regimen. Methods: This retrospective review was undertaken of 65 patients who received ≥ 2 platinum-based regimens and were assessable for secondary response in National Cancer Center Hospital between 1996 and 2008. We analyzed independent predictive factors associated with secondary response by logistic regression model and prognostic factors associated with subsequent survival by Cox regression model. Results: The median age was 54 years old (range, 28 to 73). The median follow-up of subsequent survival was 11.0 months (1.1 to 66.6). The median PFI was 11.1 months (0.7 to 77.6). Overall secondary response rate was 40%, while response rate for 36 patients after CCRT was 36%. The response increases in frequency with longer PFI ( Table ). Univariate and multivariate analyses using logistic regression model showed PFI for ≥ 9 months (odds ratio [OR] = 0.28; P =.04), PS 0 (OR = 0.19; P =.006) and maximum tumor diameter ≥ 30 mm (OR = 0.23; P =.02) were independent predictive factors of secondary response. Univariate and multivariate analyses using Cox regression model revealed PFI for ≥ 9 months (hazard ratio [HR] = 0.44; P =.005), PS 0 (HR = 0.30; P =.000) and histology of squamous cell carcinoma (HR = 2.20; P =.02) were independent prognostic factors of subsequent survival. Conclusions: Our exploratory study demonstrates that platinum free interval has both predictive and prognostic value for secondary platinum-based treatment for patients with advanced or recurrent cervical cancer.

Abstract
559 Background: Triple-negative breast cancer (TNBC) lacks the expression of estrogen receptor (ER), progesterone receptor (PgR) and HER-2. Pathological complete response (pCR) of TNBC to neoadjuvant chemotherapy (NAC) is correlated with excellent clinical outcome. We examined the value of histological parameters including tumor-infiltrating lymphocytes (TIL) and tumor cell apoptosis as surrogate markers for pCR in TNBC. Methods: Of 474 patients who received NAC and subsequent surgical therapy to stage II-III invasive breast carcinoma between 1999 and 2007, 102 (22%) had TNBC, and 92 core needle biopsy (CNB) specimens before NAC were available. We first immunohistochemically confirmed TNBC and basal-like subtype by current criteria for ER, PgR, and HER-2, cytokeratin (CK) 5/6, CK14, EGFR, and p53. All cases were TNBC, and 54 tumors (59%) were basal-like subtype defined as expression of at least one of CK5/6, CK14 and EGFR in >1% of cancer cells. Totally, 26 tumors (28%) showed pCR. Thirteen histopathological parameters were examined, and their correlation with pCR rate was tested. These parameters were also examined in resected tumor specimens from 21 non-pCR cases. Results: The pCR rate was significantly higher in the patients with tumors with TIL (24 of 68, 35%) than in those without (2 of 24, 8%, p = 0.01), and higher in tumors with high-score apoptosis (9 of 19, 47%) than in those with low-score apoptosis (17 of 73, 23%, p = 0.04). Tumors showing medullary features and p53-negative tended to show pCR more frequently (38% and 35%) than those with non-medullary features and with p53-positive (25% and 24%), but the differences were not significant. Of 21 non-pCR cases, TIL was consistently negative before and after NAC in 8, but TIL emerged after NAC in 13. The pCR rate did not differ significantly between the basal-like type (31%) and non-basal-like type (24%). Conclusions: TIL and the level of tumor cell apoptosis appeared predictive markers for response to NAC in TNBC. Patients’ host factors correlated with immune response appears play a substantial role in the response to NAC in TNBC. No significant financial relationships to disclose.

Abstract
Carcinoma of unknown primary site (CUP) is rarely encountered in clinical practice and optimal chemotherapy has not yet been established. This phase II study was conducted to evaluate the efficacy and toxicity of combined irinotecan+carboplatin therapy in chemotherapy-naive patients with CUP. Irinotecan was administered at 60 mg m(-2) as a 90-min intravenous infusion on days 1, 8 and 15. Carboplatin was administered at an area-under-the curve of 5 mg ml(-1) min as a 60-min intravenous infusion on day 1. This cycle was repeated every 28 days for up to six cycles. Forty-five patients were enrolled in the study. An intent-to-treat analysis revealed an objective response rate to the treatment of 41.9% (95% confidence interval, 27.0-57.9%). The median time to progression was 4.8 months and the median survival was 12.2 months. The 1- and 2-year survival rates were 44 and 27%, respectively. The most frequent grade 3 or more severe adverse events were leukopaenia (21%), neutropaenia (33%), anaemia (25%) and thrombocytopaenia (20%). Thus, the combination of irinotecan plus carboplatin was found to be active in patients with CUP. Therefore, the regimen may be one of the potentially available chemotherapeutic options for community standard of care in patients with a good performance status.

Abstract
A 60-year-old woman, who had undergone aortic root replacement with composite graft 5 months previously, suffered from anemia and slight fever. Transthoracic echocardiography showed pseudoaneurysm in the aortic root, and blood culture was positive. She was diagnosed with prosthetic valve endocarditis, and surgical intervention was planned. Intraoperatively necrotic tissue and dehiscence of the suture line in the aortic annulus were found. Re-aortic root replacement with Freestyle bioprosthesis and re-hemiarch graft replacement were performed with the omentopexy around the aortic root and the new graft. Antibiotics were administered intravenously for 6 weeks postoperatively. At 7 months after the operation, no prosthetic valve infection had recurred. Although the long-term results of Freestyle bioprosthesis have not been determined, it might be a valuable option for aortic root infection as an alternative to an aortic homograft. In addition, omentopexy might also be effective in the prevention of recurrent prosthetic valve infection.

Abstract
5060 Background: There have been few reports of the relationship between CA125 nadir and the prognosis in patients with advanced ovarian carcinoma (AOC) who achieve a complete clinical response by multivariate analysis. Methods: CA125 nadir and the prognosis after the initial therapy (debulking surgery + first line chemotherapy) were retrospectively investigated in patients (pts) who had AOC meeting the criteria below and received therapy at National Cancer Center Hospital, between 1998 and 2004. The eligibility criteria were: 1) histological diagnosis of mullerian carcinoma, 2) FIGO stages III and IV, 3) a combination of platinum and taxane was administered as the first line chemotherapy, and 4) achieved clinically defined complete response (CR) after the initial therapy (ie, no cancer-related symptoms; normal physical examination, computed tomography scan of the abdomen/pelvis and chest x-ray). The possibility of CA125 nadir being a prognostic factor was investigated in pts who met these criteria by multivariate analysis (age (<50 years or 50 years≤), stage (III or IV), histological type (serous adenocarcinoma (serous) or non-serous), residual tumor diameter (<2 cm or 2 cm≤) and CA125 nadir (<10 U/ml or 10 U/ml≤)) using the Cox regression model. Results: There were 84 pts with a median age of 55.5 years (26–74). The stage was III in 59 pts and IV in 25 pts, the histological type was serous in 71 pts and non-serous in 13pts, and the residual tumor diameter was <2 cm in 72 pts and >2 cm in 12 pts and the median of CA125 before the initial therapy was 535 U/ml (13–28190), the CA125 nadir was <10 U/ml in 54 pts and 10 U/ml≤ in 30 pts, respectively. Regarding the prognosis, the median progression free survival (PFS) was 19 months (6–82), and the median overall survival (OS) was 36.5 months (10–82). By multivariate analysis, the CA125 nadir was significantly associated with the prognosis (hazard ratio of PFS was 0.39 (95% CI, 0.21–0.71), hazard ratio of OS was 0.28 (95% CI, 0.11–0.72)). Conclusion: CA125 nadir is a prognostic factor in patients with AOC who achieved clinically defined CR after the initial therapy, when the cut-off value was set to 10 U/ml. CA125 nadir may be an important factor for identifying pts for whom maintenance chemotherapy is effective. [Table: see text]

Abstract
15045 Background: Limited information is available regarding to the usefulness of third-line chemotherapy (TLC) and forth-line chemotherapy (FLC) for recurrent ovarian cancer treated with first-line platinum/taxane (PT) regimens. Methods: We retrospectively reviewed the medical records of patients (pts) with ovarian cancer treated with PT regimens at the National Cancer Center Hospital from 1998 to 2004. The aim of this study is to investigate the important clinical factor such as response rate (RR), time to treatment progression (TTP), overall survival (OS) and predictor of response to TLC and FLC. Kaplan-Meier method was used for estimating TTP and OS. Wilcoxon test was performed for survival times and p-values < 0.05 were considered to be statistically significant. Results: There were 183 pts received first-line PT regimens in study period, 77 of 183 pts received second-line chemotherapy (SLC), 61 of 77 progressed after SLC and 55 of 61 pts received TLC. The RR to TLC was 34.5%. The median TTP was 5 months (mo) (range; 1–19 mo) and the median OS was 12 mo (range; 2–38 mo). The TLC regimen was consisted of P and/or T regimens of 36 pts and the other regimens of 19 pts. The RR according to the duration of response of previous chemotherapy (DRPC) (< 6 mo and ≥ 6 mo) were 31.4% and 37.3%, respectively. The median OS of DRPC (< 6 mo and ≥ 6 mo) were 8 mo (range; 2–33 mo) and 12 mo (range; 2–38 mo), respectively (p = 0.002). After TLC 47 pts progressed and 29 pts received FLC. The RR to FLC was 27.5%. The median TTP was 3 mo (range; 0–11 mo). The median OS of 18 pts who didn’t receive FLC and 29 pts received FLC were 2 mo (range; 2–16 mo) and 7 mo (range; 2–25 mo), respectively (p = 0.01). The RR according to DRPC (< 4 mo and ≥ 4mo) were 22.2% and 30%, respectively. The median OS of DRPC (< 4 mo and ≥ 4 mo) were 3 mo (range; 2–23 mo) and 6 mo (range; 2–25 mo), respectively (p = 0.4). Conclusions: The DRPC is considered to be predictor of response to TLC but not to FLC. Giving TLC and FLC if the pts have tolerable may improve OS, however this analysis is prone to several well-established potential biases and limitations. Further prospective study is warranted.

Abstract
Out of 97 cases of thymoma for the last 20 years, we have experienced 7 cases (9%) of thymoma associated with cancer of the other organs. The average age of the 7 cases was 60 years old and there were 3 females and 4 males. The organ with cancer was stomach in 3 cases, thyroid in 2, and lung, breast, colon and leukemia in one respectively. Histological classification of 8 thymomas in 7 cases was 3 epithelial type, 2 lymphocytic type and 3 mixed type. Myasthenia gravis with thymoma was only one out of them. we have to follow up carefully the patient with thymoma about occurrence of cancer of the other organs without thymus for a long time.

Abstract
We report a case of aortic arch replacement with a covered stent-graft as an "elephant trunk". A 54-year-old woman was diagnosed with Stanford type A aortic dissection. The initial intimal tear was located in the distal aortic arch. Under deep hypothermic circulatory arrest and retrograde cerebral perfusion, the distal end of the arch graft, which was turned inside out and reinforced with a Z-stent, was inserted into the distal true lumen as an "elephant trunk". Distal anastomosis was performed between the aortic wall and the inverted external graft. Graft replacement of the aortic arch and ascending aorta was followed by proximal arch grafting. Coronary artery bypass grafting to RCA was performed concomitantly. The postoperative course was uneventful, and the distal false lumen became thrombosed. This procedure is effective for reliable distal anastomosis and prevention of blood leakage into the distal false lumen.

Abstract
We reviewed 21 patients with bilateral multiple bronchogenic carcinomas. Eleven of them had synchronous carcinomas and 10 had metachronous carcinomas. We treated 6 patients with lobectomy and wedge resection under median sternotomy synchronously, and 2 patients with lobectomy on both lungs under standard thoracotomy, 2 patients with lobectomy and wedge resection, 1 patient with segmentectomy on both lung, 1 patient with lobectomy and segmentectomy, 1 patient with pneumonectomy and wedge resection, and 8 patients with lobectomy and thoracoscopic wedge resection on each lung metachronously. Two patients who had lobectomy on both lungs were dead, one of whom of pulmonary edema 2 weeks after second operation and the other of respiratory failure 3 years after second operation. We concluded that lobectomy on both lungs are not recommended because of high mortality rate (10%) and the limited resection under thoracoscopic surgery should be considered to treat the other contra lateral primary lung cancers.

Abstract
According to the results of to a survey conducted by the Japanese Society of Nuclear Medicine Technology in 1995, the mean monthly exposure dose to the trunk of nuclear medicine technicians was less than 0.2 mSv at more than 75% of the institutions, whereas the exposure dose to the fingers exceeded 0.5 mSv at 30% of the institutions. Many recent radiopharmaceuticals are being supplied as the syringe type, and while the syringe is surrounded by a tungsten or lead-glass shield, there is no shielding of the syringe needle or the plungers. The plastic plunger provides little shielding effect, and even when a tungsten plunger is used, calculating back from the leakage rate, the shielding effect for 99mTc is approximately 75%. We therefore trial-manufactured a plunger devised in such a manner as to considerably reduce exposure of the fingers and evaluated its shielding effect from leakage rate obtained with a dual-detector scintillation camera when the radionuclides 99mTc, 67Ga, 201Tl, and 123I were used. Its performance was satisfactory, with shielding effects (99mTc, 99%; 67Ga, 95%, 201Tl, 95%; 123I, 73%) about the same or better than back-calculated from the leakage rates.

Abstract
The opportunities to use the syringe-type radiopharmaceuticals being supplied by manufacturers to conduct examinations in the ordinary clinical practice of nuclear medicine have recently increased, and the radiation doses to the fingers of those performing the examinations has been reduced. However, not much is known about the shielding effect of the syringe-type syringe shields and plungers. In order to evaluate their shielding effect, we devised a method in which leakage rates are calculated from the counts of the image data acquired with a 2-detector scintillation camera and compared with the values and graphs. The values made it possible to determine and compare single-direction leakage rates, whereas the graphs made it possible to determine and compare 360 degrees-direction leakage rates. This method is convenient, enables satisfactory result to be obtained in any institution, and appears to make it easy to understand the shielding effect. The validity of this method was confirmed in a comparative assessment with a survey-meter.

Abstract
Alteration of the p53 gene product occurs frequently during the progression of colorectal cancer. Recently, mutated p53 protein was found to induce the production of anti-p53 antibodies in the serum of patients. The purpose of this study was to evaluate the relationship between p53 status in serum and chemosensitivity in resectable colorectal cancer patients. A total of 35 patients with primary colorectal cancer who underwent surgical treatment were examined by chemosensitivity test with the viable tumor samples using Histoculture Drug Response Assay (HDRA). Serum samples of these patients to test for p53 antibodies were obtained before tumor resection, and assayed in duplicate by using an enzyme-linked immunosorbent assay (ELISA) kit. The inhibition index of 5-FU and CDDP, determined by the HDRA method, in the sero-positive group was significantly lower than that of the sero-negative group (p < 0.01). Furthermore, significant statistical differences in chemosensitivity to 5-FU and CDDP were revealed depending on the presence of serum p53 antibodies. There was no relationship between chemosensitivity assay and tumor marker positivity or clinicopathological features in these patients. Detection of serum p53 antibodies, which reflects p53 mutations in tumor tissue, is a simple method which correlates with chemosensitivity, and may contribute to the selection of favorable chemotherapeutic strategies of colorectal cancer.

Abstract
p53 protein overexpression was found to induce the production of antibodies in patient serum and, recently, the easy detection of serum antibodies has been made possible. The aim of this study is to determine the significance of serum p53 antibodies in patients with primary colorectal adenocarcinoma in comparison with their clinicopathological features, and the tumor marker sensitivities of carcinoembryonic antigen (CEA), carcinoma antigen 19-9 (CA19-9) and alpha-fetoprotein (AFP). Thirty-nine of 86 patients (45.3%) were positive for serum p53 antibodies. However, there was no relation with the cancer progression or clinicopathological findings. The sensitivities of CEA, CA19-9 and AFP were 36.0%, 38.4%, and 8.1% respectively, but there was no relation between serum p53 antibodies and these three markers. When the sensitivity of serum p53 antibodies and CEA was evaluated according to clinical stage, the presence of serum p53 antibodies was more significantly associated with stage 0, I and II colorectal cancer than was CEA. Thirty-three patients who showed preoperative positivity for serum p53 antibodies were followed by serial evaluation of circulating antibodies after resection. Negative conversions after resection were significantly higher in the "Cur A" group than in the "Cur B" or "Cur C" groups. Serum p53 antibodies appear to be a useful tumor marker independent of the other markers, especially in the early stage, and are expected to be useful in the development of a method of early diagnosis for mass screening, and as a postoperative monitoring marker for colorectal cancer.

Abstract
For 6 patients with advanced hepatocellular carcinoma (HCC) in whom TAE was inefficacious, we tried hepatic arterial infusion chemotherapy. 5-FU 500 mg/day + CDDP 10 mg/day was administered during 5 days. The AFP level was decreased for 4 patients, and 2 patients showed a partial response in CT image. These 2 patients have been alive over 22 and 18 months, respectively. These results suggest that 5-FU + CDDP HAI might be a useful treatment of HCC inefficacious with TAE.

Abstract
Transitional epithelium of mammalian urinary bladder is a functional barrier which prevents passage of urine into the submucosa. In a previous study, we found uptake by the epithelial cells of horseradish peroxidase (HRP) instilled into the mouse bladder lumen. In the present study, the ability of bladder epithelial cells to take up HRP, which was visualized by the diaminobenzidine (DAB) reaction, was compared among several mammalian species by light and electron microscopy. In mouse, rabbit and dog bladder, the superficial cells of the transitional epithelium showed positive reactions for HRP, while cells in lower epithelial layers were DAB-negative. Some of the reaction products could be seen as a number of granules not surrounded by a membrane. The intercellular space of the epithelium was DAB-negative. In rat and guinea pig bladder, however, all urothelial cells showed negative reactions for HRP indicating that no uptake of HRP had been occurred in these animals. These results indicate that the uptake of HRP by the superficial cells of the bladder epithelium differs among mammalian species, indicating some functional differences in their superficial cells.

Abstract
The effects of methylprednisolone succinate (MP) on plasma lipid peroxidation, plasma SOD activity and superoxide production in polymorphonuclear leukocytes (PMNs) induced by lipopolysaccharide (LPS) were examined in rats in vivo and in vitro. In rats subjected to LPS treatment, plasma phosphatidylcholine hydroperoxide (PCOOH) levels significantly increased, and the plasma Cu,Zn-SOD activity decreased by about 75%. When rats were given 30 mg/kg of MP intravenously, MP suppressed the elevation of plasma PCOOH levels and partially inhibited the decrease in plasma Cu,Zn-SOD activity. MP also suppressed PMA-induced superoxide production in PMNs primed by LPS. In in vitro experiments, low concentrations of MP had no effect on NADPH-dependent lipid peroxidation, but 4 mM MP produced 50% inhibition. MP had little effect on PMA-induced superoxide production in PMNs primed by LPS. Moreover, MP had no radical-trapping effect on superoxide, hydroxyl radical and stable DPPH radical. These results suggest that the suppressive effect of plasma lipid peroxidation by MP is not due to radical-trapping effects or preventive anti-oxidation, but may involve the suppression of the lipid chain reaction in liver membrane resulting from PMA-induced superoxide anions generated by PMNs.

Abstract
The patient was a 62-year-old woman who was referred to our department for bilateral diffuse abnormal shadows along with a sigmoid colon cancer that had been resected one month previously. Thoracoscopic partial resection of the left S8 region was performed. Nd-YAG laser with a contact tip was used for the resection. Hemostasis at the bed of the resection was assured by applying a free laser beam to oozing and non-coagulated surface. Additionally, the resected end was closed by standard continuous double over-and-over sutures in order to minimize the air leakage. Endo-Bulldog clamp facilitated the operation, minimizing hemorrhage from the resected end. This device can clamp any part of the lung and save one percutaneous puncture site necessary for thoracoscopic procedures. Postoperative course was uneventful. Pathological diagnosis was reported as an alveolar cell carcinoma of the lung.

Abstract
Rat urinary bladder epithelium consists of basal, intermediate and superficial cell layers. The superficial cells (SP cells) were desquamated after 12-O-tetradecanoylphorbol-13-acetate (TPA)-treatment, and the morphological changes of the regenerating epithelium were investigated by scanning and transmission electron microscopy. Twenty-four hours after TPA-treatment, the epithelium had principally two cell layers and no typical SP cells were observed. During the next 24 hours, the epithelial cell layers became irregular as the epithelial cells with multiform cell projections interdigitated with each other and more than five layers of cell stratification were observed. These cells were bright and had large round nuclei. Their luminal surfaces at this stage were triangular or rectangular. Four days after TPA treatment, epithelial stratification was reduced to approximately three cell layers and some of the luminal cells had recovered the fusiform vesicles. Eight days after TPA treatment, most regions of the epithelium had returned to normal and typical SP cells with many fusiform vesicles had regenerated. These results indicate that the regeneration of bladder epithelium after TPA treatment occurred within about one week.

Abstract
We encountered two cases of Harada's disease in monozygotic twins, and this is the first such report as far as could be determined. Case 1 was a 32-year-old woman who presented a typical clinical picture of Harada's disease. Seven years later, case 2 (the younger sister), also presented with the disease at 39 years of age. Case 2 had a transitional diffuse type of Harada's disease, which was possibly due to differences in her treatment. Both patients had papilledema. Since these twins both developed Harada's disease, it is suggested that hereditary factors including HLA type are very important in its development. The HLA type of both these patients was A2, A26, B51, B7, CW7, DR1, and DR4.

Abstract
A 46-year-old man was admitted to Oita Medical College Hospital on October 16, 1987, because of cough and sputum. Chest X-ray and chest CT films showed diffuse reticulonodular shadow. The specimens obtained by transbronchial lung biopsy revealed cysts of pneumocystis carinii. Abnormal lymphocytes with lobulated nuclei were found 2-7% of peripheral leucocytes. The anti HTLV-I antibody was positive. According to these data, we diagnosed the patient as smoldering adult T cell leukemia with pneumocystis carinii pneumonia. The abnormal shadow on chest X-ray disappeared after SMX-TMP and pentamidine treatment. After about 1 year, he was again admitted for high fever. Chest X-ray showed infiltration with cavity in right upper lobe. Streptococcus pneumoniae was isolated from the sputum. The infiltration shadow on chest X-ray disappeared after antibiotics treatment. However, multiple nodular shadow appeared on the chest X-ray and ATL cell infiltration was found in the specimens of transbronchial lung biopsy. ATL cells in peripheral blood also increased and serum LDH and Calcium levels were markedly high. According to these data, we diagnosed the patient as having a ATL crisis. Although chemotherapy for ATL was started, the ATL, cell infiltration shadow on the chest X-ray enlarged, and bilateral diffuse patchy shadows was appeared on the chest X-ray. He died of respiratory failure on April 26, 1989. Cytomegalovirus pneumonia and ATL cell infiltration were revealed by necropsy.

Abstract
We have recently discovered that hypothermic cerebral retrograde perfusion can be performed by simply elevating the central venous pressure in Trendelenburg's position during aortic arch surgery. During deep hypothermic perfusion of the lower half of the body with an occlusion balloon in the descending aorta, oxygen saturated venous blood supplied the brain with oxygen. A successful case is reported. A case was 53 y.o. woman of dissecting aortic aneurysm DeBakey type II, with a true aortic arch aneurysm. Under median sternotomy the right atrium and the femoral artery were cannulated for cardiopulmonary bypass. With the brain under retrograde perfusion at a rectal temperature of 16 degrees C and a central venous pressure of 10-15 mmHg, the ascending to the descending aorta was replaced. Blood flowed into the aortic arch from the arch vessels was blackish in color. Brain circulatory arrest time was 81 min. Postoperative course was uneventful. It is suggested that this simple retrograde cerebral perfusion during hypothermic aortic arch surgery protected the brain for an extended brain circulatory arrest time, and eliminated the need for clamping at the aortic arch and the arch vessels, and simplified the operative procedure.

Abstract
A case of basilar artery occlusion after STA-SCA bypass surgery is reported. The patient was a 56 year old male and presented a TIA of vertigo and speech disturbance. The preoperative angiogram revealed severe stenosis of the basilar artery in its midportion between the bifurcation of AICA and that of SCA. After surgery, the patient's clinical course was uneventful, but the angiogram showed that the previous stenotic segment of the basilar artery had been occluded and the distal portion of the basilar artery and its branches were perfused through the widely-patent STA-SCA bypass. About 6 months after the operation, the patient developed a pontine infarction in the right paramedian region, which was confirmed on MRI. The angiogram revealed that the occlusion of the basilar artery extended further proximally to a point just distal to the bifurcation of AICA. So it was suspected that the perforating branches of the basilar artery to the pons were occluded with the extension of the thrombosis of the basilar artery. The hemodynamic changes associated with the EC-IC bypass was thought to be responsible for the occlusion of the previous stenotic lesion.

Abstract
144 cases of the superficial esophageal cancer, of which invasion was limited to the submucosa, have been resected for the last 23 years. 94 cases (65%) were early cancer, and 50 cases (35%) were superficial cancer with metastasis. The 5-year survival rate of early cancer cases was 65%, otherwise, that of superficial cancer cases with metastasis was 24%. There was a significant difference between these two groups. As for the depth of cancerous invasion, the 5-year survival rate of mucosal cancer cases was 100%. That of submucosal cancer cases was 70% even in cases without nodal involvement. Analyzing the cancerous depth of the superficial cancer and its nodal involvement and its vascular invasion, the lymph node metastasis and the vascular invasion were not observed in 90% of mucosal cancer cases, otherwise these were negative only in 30% of submucosal cancer cases. So to obtain the remarkable improvement of the long term results of esophageal cancer, the diagnosis and the treatment of mucosal cancer of the esophagus are essential. The endoscopic examination have come to play a large role for the diagnosis of mucosal cancer of the esophagus. Moreover, the endoscopic dyeing with Lugol's solution is important in the diagnosis of flat type of esophageal lesions, that is mucosal cancer and epithelial cancer. At present time, the treatment of early esophageal cancer is in principle surgery. And the operative mortality was low, 1.4%. However, the non-invasive treatments; endoscopic LASER therapy, radiation, endoscopic strip-biopsy etc., will be performed more frequently in minute mucosal cancer.

Abstract
A case of a primary hepatic carcinosarcoma, a very uncommon liver tumor in adults, demonstrated by Ga-67 scintigraphy, was reported. The liver image showed a lesion of low activity in the left lobe of the liver, whereas the Ga-67 image showed a moderate accumulation in the lesion detected by the liver scan and further indicated a high accumulation extending downwards from the hepatic lesion. An autopsy revealed that the huge abdominal tumor was composed of hepatocellular carcinoma and malignant mesenchymoma in the left hepatic lobe and in the lower part of the tumor, respectively. The Ga-67 image demonstrated these two different histological components of the tumor.
