Abstract
Adenoid cystic carcinoma (ACC) is a rare type of malignant tracheal tumor originating from the secretory glands. Complete surgical resection is the current standard of care for tracheal ACC. However, there have been few case reports of chemoradiotherapy for unresectable tracheal ACC. We herein report a 28-year-old man with unresectable tracheal ACC who received concurrent chemoradiotherapy (CCRT) followed by maintenance therapy with durvalumab. CCRT was completed with a good response and safety, and the patient is currently receiving durvalumab as maintenance therapy. Durvalumab after CCRT can be a treatment option for patients with unresectable tracheal ACC.

Abstract
Alectinib is a selective anaplastic lymphoma kinase (ALK) tyrosine kinase inhibitor as standard therapy for ALK-rearranged non-small cell lung cancer (NSCLC). Hemolytic anemia is considered as a rare but significant adverse event with alectinib. Here, we report a case of a 73-year-old female with lung adenocarcinoma, harbouring an ALK fusion gene, who received alectinib as second-line therapy and developed gradually progressive grade 4 (6.4 g/dL) drug-induced hemolytic anemia (DIHA) after complete response. We discontinued alectinib and performed a blood transfusion for the severe anemia. The anemia improved with no recurrence of lung adenocarcinoma over 10 months. Regular hematologic monitoring and the possibility of DIHA should be considered in case of progressive hemolytic anemia during alectinib treatment.

Abstract
SUMMARY A 31-year-old man with Williams syndrome (WS) was referred to our hospital because of a 9-year history of hypertension, hypokalemia, and high plasma aldosterone concentration to renin activity ratio. A diagnosis of primary aldosteronism (PA) was clinically confirmed but an abdominal CT scan showed no abnormal findings in his adrenal glands. However, a 13-mm hypervascular tumor in the posterosuperior segment of the right hepatic lobe was detected. Adrenal venous sampling (AVS) subsequently revealed the presence of an extended tributary of the right adrenal vein to the liver surrounding the tumor. Segmental AVS further demonstrated a high plasma aldosterone concentration (PAC) in the right superior tributary vein draining the tumor. Laparoscopic partial hepatectomy was performed. The resected tumor histologically separated from the liver was composed of clear cells, immunohistochemically positive for aldesterone synthase (CYP11B2), and subsequently diagnosed as aldosterone-producing adrenal adenoma. After surgery, his blood pressure, serum potassium level, plasma renin activity and PAC were normalized. To the best of our knowledge, this is the first report of WS associated with PA. WS harbors a high prevalence of hypertension and therefore PA should be considered when managing the patients with WS and hypertension. In this case, the CT findings alone could not differentiate the adrenal rest tumor. Our case, therefore, highlights the usefulness of segmental AVS to distinguish adrenal tumors from hepatic adrenal rest tumors. LEARNING POINTS Williams syndrome (WS) is a rare genetic disorder, characterized by a constellation of medical and cognitive findings, with a hallmark feature of generalized arteriopathy presenting as stenoses of elastic arteries and hypertension. WS is a disease with a high frequency of hypertension but the renin-aldosterone system in WS cases has not been studied at all. If a patient with WS had hypertension and severe hypokalemia, low PRA and high ARR, the coexistence of primary aldosteronism (PA) should be considered. Adrenal rest tumors are thought to arise from aberrant adrenal tissues and are a rare cause of PA. Hepatic adrenal rest tumor (HART) should be considered in the differential diagnosis when detecting a mass in the right hepatic lobe. Segmental adrenal venous sampling could contribute to distinguish adrenal tumors from HART.

Abstract
Abdominal ultrasonographical and computed tomography examinations of a 12-year-old neutered female toy poodle revealed a protruding mass, approximately 2 cm in diameter, at the apex of the bladder. The mass was firm and haemorrhagic with a homogeneously brownish-yellow cut surface. Microscopically, it was unencapsulated and located in the muscle layer with invasion of the extra-muscular layer. It was composed of spindloid to oval neoplastic cells that formed irregular clefts and diffuse sheets that dissected bundles of collagen. Immunohistochemically, the neoplastic cells were positive for vimentin and lymphatic vessel endothelial hyaluronan receptor 1 antigens, but negative for cytokeratin AE1/AE3, factor VIII-related antigen, CD31, CD34, Prox-1, S100, desmin, α-smooth muscle actin and MyoD1. Negative immunolabelling for laminin antigen supported the absence of evidence of a basal lamina on ultrastructural examination. Based on these findings, this tumour was identified as a lymphangiosarcoma. To the best of our knowledge, this case is the first report of lymphangiosarcoma arising from the bladder in a dog.

Abstract
BACKGROUND A survival benefit of extensive intraoperative peritoneal lavage (EIPL) has been reported in patients with gastric cancer with positive peritoneal cytology. The hypothesis of this study was that EIPL may reduce peritoneal recurrence in patients with advanced gastric cancer who undergo surgery with curative intent. METHODS This was an open-label, multi-institutional, randomized, phase 3 trial to assess the effects of EIPL versus standard treatment after curative gastrectomy for resectable gastric cancer of T3 status or above. The primary endpoint was disease-free survival (DFS); secondary endpoints were overall survival, peritoneal recurrence-free survival and incidence of adverse events. RESULTS Between July 2011 and January 2014, 314 patients were enrolled from 15 institutions and 295 patients were analysed (145 and 150 in the EIPL and no-EIPL groups respectively). The 3-year DFS rate was 63·9 (95 per cent c.i. 55·5 to 71·2) per cent in the EIPL group and 59·7 (51·3 to 67·1) per cent in the control group (hazard ratio (HR) 0·81, 95 per cent c.i. 0·57 to 1·16; P = 0·249). The 3-year overall survival rate was 75·0 (67·1 to 81·3) per cent in the EIPL group and 73·7 (65·9 to 80·1) per cent in the control group (HR 0·91, 0·60 to 1·37; P = 0·634). Peritoneal recurrence-free survival was not significantly different between the two groups (HR 0·92, 0·62 to 1·36; P = 0·676). No intraoperative complications related to EIPL were observed. CONCLUSION EIPL did not improve survival or peritoneal recurrence in patients who underwent gastrectomy for advanced gastric cancer.

Abstract
Background: Williams syndrome (WS) is a microdeletion disorder caused by heterozygous loss of approximately 1.5-Mb pairs of DNA from chromosome 7. Patients with WS have a characteristic constellation of medical and cognitive findings, with a hallmark feature of generalized arteriopathy presenting as stenoses of elastic arteries and hypertension. We present here a case of WS associated with primary aldosteronism (PA), whose source of aldosterone excess was difficult to locate. Clinical case: A 31-year-old man suspected having PA was referred to our Hospital. He was diagnosed as having Williams syndrome at 2 months of age. He had been hypertensive for 9 years. At the age of 31 years old, low serum potassium (K) and high aldosterone to renin ratio were pointed out. His plasma renin activity (PRA) was 0.2 ng/ml/h, plasma aldosterone concentration (PAC) was 456 pg/ml, serum K level was 3.1 mEq/l at admission. Diagnosis of PA was confirmed according to positive captopril challenge test. CT scan revealed a 13mm tumor with low density in posterosuperior segment of right hepatic lobe, but adrenal tumor was not detected. Venography of adrenal vein sampling (AVS) showed an extended tributary of the right adrenal vein to the liver that surrounded the tumor. Segmental AVS was performed for right adrenal vein and showed a high value of PAC (377000 pg/ml) in superior tributary which was drained from the tumor. PAC in other tributaries of right adrenal vein and left adrenal vein was suppressed. Laparoscopic partial hepatectomy was performed as a liver tumor. After surgery, serum K level was normalized, PAC decreased to 67 pg/ml. Pathological examination revealed a golden-yellow tumor separated from the liver by fibrous septum. The tumor was attached to an adrenal cortex embedded in the liver. The tumor was composed of clear cells, positive for 3βHSD2 and CYP11B2 using immunohistochemistry, diagnosed as aldosterone producing adrenal adenoma. Conclusion: To the best of our knowledge, this is the first report of WS associated with PA. Since WS is a disease with high prevalence of hypertension, measurement of PRA and PAC for screening of PA is recommended for patients with WS associated with hypertension. According to CT findings, hepatic adrenal rest tumor was suspected because the tumor was not continuous with the right adrenal gland, but pathological findings demonstrated that an adrenal adenoma was originated from right adrenal cortex rather embedded in the liver. Segmental AVS was useful to distinguish adrenal tumor from hepatic adrenal rest tumor.

Abstract
Abstract
Background
The outcome for pT1 N+ or pT2–3 N0 gastric cancer is favourable, but some patients suffer from recurrent disease. The aim of this study was to identify prognostic factors in patients with pT1 N+ or pT2–3 N0 gastric cancer.
Methods
This was a multicentre, retrospective cohort study. All patients with pT1 N+ or pT2–3 N0 gastric cancer who underwent curative gastrectomy at five high-volume, specialized cancer centres in Japan between 2000 and 2008 were included. Demographic, clinical, surgical and pathological data were collected. Independent prognostic factors were identified using a Cox proportional hazards regression model.
Results
Some 1442 patients were included. The 5-year overall survival rate for patients with pT1 N+ or pT2–3 N0 gastric cancer was 92·0 per cent. Multivariable analysis for overall survival identified age (hazard ratio (HR) 2·67, 95 per cent c.i. 2·09 to 3·43), sex (HR 0·57, 0·39 to 0·83) and clinical tumour depth (cT) (HR 1·45, 1·06 to 1·98) as independent prognostic factors.
Conclusion
Survival of patients with pT1 N+ or pT2–3 N0 gastric cancer is good. Age 65 years or above, male sex and cT2-4 category are associated with worse overall survival.

Abstract
INTRODUCTION Anorectal abscess is one of the most common anorectal conditions encountered in practice. However, such abscesses may rarely extend upward and cause life-threatening medical conditions. PRESENTATION OF CASE A 53-year-old woman presented with symptoms of anorectal abscess and evidence of severe inflammatory response and acute kidney injury. Computed tomography revealed a widespread abscess extending to the bilateral retroperitoneal spaces. Surgical drainage was performed via a totally extraperitoneal approach through a lower midline abdominal incision, and the patient had a rapid and uncomplicated recovery. DISCUSSION Although retroperitoneal abscesses originating from the anorectal region are rare, they are life-threating events that require immediate treatment. Percutaneous abscess drainage has been recently evolved; however, surgical drainage is required sometimes that may be challenging, particularly in the case of widespread abscesses, as in our case. CONCLUSION The midline extraperitoneal approach reported here might be an effective surgical option for patients with bilateral widespread retroperitoneal abscesses.

Abstract
Time-resolved X-ray absorption spectroscopy was performed for aqueous ammonium iron(III) oxalate trihydrate solutions using an X-ray free electron laser and a synchronized ultraviolet laser. The spectral and time resolutions of the experiment were 1.3 eV and 200 fs, respectively. A femtosecond 268 nm pulse was employed to excite [Fe(III)(C2O4)3](3-) in solution from the high-spin ground electronic state to ligand-to-metal charge transfer state(s), and the subsequent dynamics were studied by observing the time-evolution of the X-ray absorption spectrum near the Fe K-edge. Upon 268 nm photoexcitation, the Fe K-edge underwent a red-shift by more than 4 eV within 140 fs; however, the magnitude of the redshift subsequently diminished within 3 ps. The Fe K-edge of the photoproduct remained lower in energy than that of [Fe(III)(C2O4)3](3-). The observed red-shift of the Fe K-edge and the spectral feature of the product indicate that Fe(III) is upon excitation immediately photoreduced to Fe(II), followed by ligand dissociation from Fe(II). Based on a comparison of the X-ray absorption spectra with density functional theory calculations, we propose that the dissociation proceeds in two steps, forming first [(CO2 (•))Fe(II)(C2O4)2](3-) and subsequently [Fe(II)(C2O4)2](2-).

Abstract
BACKGROUND To our knowledge, no reports have evaluated the effects of genetic polymorphisms of insulin-like growth factor-I (IGF-I) on clinical outcomes of gastric cancer patients. METHODS We retrospectively analyzed the impact of IGF-I polymorphisms on recurrence-free survival (RFS) in 430 patients with gastric cancer who underwent curative gastrectomy between 2001 and 2005 in our institution. RESULTS Among the 430 gastric cancer patients, 345 were pathological stage I or II, while 85 were stage III or IV. The median 5-year RFS rate was 85.3% (95% confidence interval [CI] 81.4-88.5). In a multivariate Cox model (adjusted for age, gender, histology, pathological stage, adjuvant chemotherapy, and history of diabetes), two IGF-I polymorphisms, rs1520220 and rs2195239, were significantly associated with RFS (hazard ratio [HR] 0.60, 95% CI 0.40-0.91; and HR 0.60, 95% CI 0.41-0.89, respectively, in a per-allele model). When stratified by stage (I-II versus III-IV), rs1520220 in particular was associated with RFS in patients with stage III-IV disease, with a P-value for interaction of 0.01. CONCLUSIONS Our findings indicate that genetic polymorphisms of IGF-I may have a substantial effect on recurrence for gastric cancer patients who have undergone curative gastrectomy. This information may help identify population subgroups that could benefit from IGF-I-targeting agents.

Abstract
Galanin receptor 1 (GALR1) maps to a common region of 18q loss in head and neck squamous cell carcinomas and is frequently inactivated by methylation. To investigate effects of GALR1 and its signaling pathways, we stably expressed hemaglutinin-tagged GALR1 in a human oral carcinoma cell line (UM-SCC-1-GALR1) that expresses no endogenous GALR1. In transfected cells, galanin induced activation of the extracellular-regulated protein kinase-1/2 (ERK1/2) and suppressed proliferation. Galanin stimulation mediated decreased expression of cyclin D1 and increased expression of the cyclin-dependent kinase inhibitors (CKI), p27(Kip1) and p57(Kip2). Pretreatment with the ERK1/2-specific inhibitor U0126 prevented these galanin-induced effects. Phosphatidylinositol 3-kinase (PI3K) pathway activation did not differ in UM-SCC-1-GALR1 and UM-SCC-1-mock cells after galanin treatment. Pertussis toxin and LY294002 inhibition demonstrated that galanin and GALR1 induce ERK1/2 activation via Galphai, not the PI3K pathway-linked to the Gbetagamma subunit. Galanin and GALR1 also inhibit colony formation and tumor growth in vivo. Our results implicate GALR1, a Gi protein-coupled receptor, as a tumor suppressor gene that inhibits cell proliferation via ERK1/2 activation.

Abstract
Pseudomyxoma peritonei is generally caused by appendiceal and ovarian tumors. Other primary sites have been rarely reported. We describe herein the second reported case of pseudomyxoma peritonei due to mucinous cystadenocarcinoma of the urachus. A 54-year-old man was admitted with a left inguinal hernia that had developed several months prior to his admission. During herniorrhaphy, we found a large amount of gelatinous mucinous material in the indirect-hernia sac and made a diagnosis of pseudomyxoma peritonei on cytological grounds. At re-operation, the origin of the pseudomyxoma peritonei proved to be a ruptured urachal cyst. The urachal cyst and the dome of the urinary bladder were excised. In addition, we removed as much of the gelatinous material as possible. On histological examination, a unilocular cyst was found to consist of noninvasive mucinous adenocarcinoma. We succeeded in removing the rest of the mucinous material by postoperative intraperitoneal lavage with dextran solution, and have observed no evidence of recurrence for 7 years since the operation.

Abstract
In a 72 years old woman, abdominal computed tomography (CT) disclosed multicentric hypervascular tumor in S4 of the liver, and it was T1.T2 by the MRI, and a high signal was presented together. Stenosis was shown by ERCP at the same site. Cholangiocellular carcinoma was suspected before operation, but malignant change was not recognized by frozen section, so the operation was finished. Later, a diagnosis of solitary necrotic nodule of the liver was established by pathological diagnosis. Solitary necrotic nodule of the liver is a benign tumor.

Abstract
BACKGROUND In endoscopic surgery, one of the greatest problems is the difficulty with the reconstructive procedure. This problem frequently makes operating times longer. The authors have performed thoracoscopic esophagectomy and intrathoracic esophagogastric anastomosis for reconstruction using a circular stapler for the esophageal cancer. Although the circular stapler is a useful device for gastrointestinal anastomosis, it was difficult to place a purse-string suture and to fixate the anvil into the proximal esophagus endoscopically. METHODS The authors devised a new procedure for the placement of the purse-string suture by using an Endo-Stitch device along with a new method to incise the esophageal wall and thereby facilitate fixation of the anvil. RESULTS The authors attempted this procedure for five patients. The anastomoses were performed successfully. CONCLUSIONS The new procedure can make endoscopic intrathoracic anastomosis feasible and safe. In addition, this procedure can be applied widely to other endoscopic reconstructions.

Abstract
BACKGROUND Assessment of malignant potential in gastrointestinal stromal tumors (GISTs) is still problematic. The maximum tumor diameter and the mitotic index are generally used as an index of malignancy of GISTs. The Ki-67 labeling index has recently been used as an index of cell growth, and the prognosis of GISTs was reported to be significantly poor when the value of this index was 10% or higher. METHODS Clinicopathological and immunohistological factors were analyzed in 15 patients who underwent surgical resection of gastric stromal tumors at our department between April 1997 and July 2002. The patients were divided into "metastasis/recurrence" and "benign" groups. Also, the relationship of changes in the Ki-67 labeling index to the degree of malignancy in recurrent lesions was assessed in an 84-year-old woman who underwent five reoperations because of recurrences in the peritoneum. RESULTS Significant differences were noted between the metastasis/recurrence and benign groups in relation to the mean maximum tumor diameter (186.7 +/- 80.8 mm vs 41.3 +/- 22.9 mm), mitotic index (88.3 +/- 5.0/50 high-power fields [HPF] vs 3.0 +/- 2.9/50 HPF), and the Ki-67 labeling index (11.4 +/- 2.5% vs 0.01 +/- 0.51%). In the patient who had metastasis to the liver 3.5 years after initial operation and underwent five reoperations before death, the intervals until detection of recurrence tended to be shortened gradually. The Ki-67 labeling index varied with each operation, and tended to be higher at the time of reoperations than at the initial operation. CONCLUSION The maximum tumor diameter, mitotic index, and Ki-67 labeling index were useful as an index of malignancy for gastric stromal tumor. The efficacy of surgical resection alone may be insufficient in patients with disseminated metastasis to the peritoneum.

Abstract
A 64-year-old-male had recurrent paraaortic lymph node and liver metastases eight months after total gastrectomy and with distal pancreatectomy and splenectomy for advanced gastric cancer. Combined chemotherapy with 5-FU and a low-dose of CDDP was effective and the both lesions disappeared. Thirteen months later, a second recurrence of anterior mediastinum lymph node metastases occurred. After the same protocol, the lesions showed a partial response and lymph node dissection was performed. Histopathological examination showed that the resected lymph nodes had 99% necrosis and fibrotic change. Immunohistochemical examination of p53 of the primary gastric cancer showed negative staining. The patient has been followed for three years after the operation, and has no recurrent lesions.

Abstract
We performed stem cell rescue and allogeneic skin transplantation on a lethally neutron-irradiated nuclear accident victim. HLA-DRB1 mismatched unrelated umbilical cord blood cells (2.08 x 10(7)/kg recipient body weight) were transplanted to an 8-10 Gy equivalent neutron-irradiated patient because of a lack of a suitable bone marrow or peripheral blood donor. Pre-transplant conditioning consisted of anti-thymocyte gamma-globulin alone, and GVHD prophylaxis was a combination of cyclosporine (CYA) and methylprednisolone (mPSL). Granulocyte colony-stimulating factor (G-CSF), erythropoietin (EPO), and thrombopoietin (TPO) were concurrently administered after transplantation. The absolute neutrophil count reached 0.5 x 10(9)/l on day 15, the reticulocyte count rose above 1% on day 23, and the platelet count was over 50 x 10(9)/l on day 27, respectively. Cytogenetic studies of blood and marrow showed donor/recipient mixed chimerism. Rapid autologous hematopoietic recovery was recognized after withdrawal of CYA and mPSL. Repeated pathological examinations of the skin revealed no evidence of acute GVHD. Eighty-two days after the irradiation, skin transplantation was performed to treat radiation burns. Almost 90% of the transplanted skin engrafted. Immunological examination after autologous hematopoietic recovery revealed an almost normal T cell count. However, immune functions were severely impaired. The patient died from infectious complication 210 days after the accident.

Abstract
For prone position except for neurosurgery or cervical spinal surgery, head and neck are usually turned sideways on the pillow. This position has a risk of injuries to eyes, nose, lips, ears, or facial nerve and inducing neck pain after surgery. We introduce new tools to avoid these complications from prone position. The ProneView consists of a plastic helmet with a window for eyes, nose and mouth, a sponge to fit the face attached to the helmet, and a mirror to watch eyes, nose and lips. The OPTI-GARD is the glasses made by a sponge with a plastic windows to protect eyes. Using the ProneView and the OPTI-GARD together, patient's neck and head can be kept at neutral position with eyes, nose, lips, and ears being kept free from any pressure. In addition, we can check the position of the face easily by mirror. Therefore, the ProneView and the OPTI-GARD must be useful to decrease injuries to eyes, nose, lips, ears, and facial nerve, and neck pain in prone position.

Abstract
1. In the present study, we investigated the prophylactic effects of pilocarpine hydrochloride on xerostomia models induced by either single (15 Gy) or repeated (8.6 Gy x3 days) X-ray irradiation in rats. Pilocarpine hydrochloride was administered orally 90 min before each irradiation session. Then, 7 days later, salivary volume, amylase activity and protein concentration in the saliva secreted from the right parotid gland were measured before and after a subsequent administration of pilocarpine hydrochloride (intraduodenal). 2. In irradiated no-pretreatment rats, irradiation induced a significant reduction in both spontaneous and pilocarpine hydrochloride-stimulated secretion (both total salivary volume and flow rate), regardless of the protocol used for X-ray exposure. In irradiated, pilocarpine hydrochloride-pretreated rats, salivary secretion was increased after stimulation by pilocarpine hydrochloride (intraduodenal) to a degree that depended on the pretreatment dose of pilocarpine hydrochloride (p.o.) in both xerostomia models. 3. There were no differences in amylase or protein concentrations between irradiated rats pretreated with pilocarpine hydrochloride and irradiated no-pretreatment control rats. 4. A decrease in the weight of the parotid gland was observed in rats exposed to either the single dose or repeated irradiation protocols. Changes in the submandibular gland were less marked than those in the parotid gland. These changes in gland weight were not affected by pilocarpine hydrochloride pretreatment. 5. The responsiveness of the parotid gland to subsequent stimulation with pilocarpine hydrochloride was apparently preserved in both xerostomia models by pretreatment with pilocarpine hydrochloride, which itself increased salivary secretion. This suggests that pilocarpine hydrochloride may exert functional protective effects against xerostomia that occurs following irradiation therapy through a stimulation of salivary secretion.

Abstract
Hypoglycemic agents with a rapid onset and short duration of action should be useful for controlling postprandial hyperglycemia. Our aim was to establish a diabetes mellitus model in dogs, and then during an oral glucose tolerance test to compare the hypoglycemic effect and insulinotropic action of KAD-1229, a new hypoglycemic agent, with that of gliclazide, a conventional sulfonylurea. In this model, KAD-1229 reduced the increase in plasma glucose level without producing hypoglycemia. Gliclazide had a weaker effect on reduction of the glucose increase and caused hypoglycemia via a significantly raised insulin secretion in the late phase. A rapid insulinotropic action of KAD-1229 was clearly observed in the portal venous blood. The results suggest that in type 2 diabetes caused by, at least, insulin deficiency, KAD-1229 may improve impaired insulin secretion in the early phase and attenuate hyperglycemia without causing a sustained hypoglycemia.

Abstract
We report our experience with transperitoneal laparoscopic adrenalectomy in 26 cases (mean age 45 years). We experienced primary aldosteronism in 19 cases, Cushing syndrome in 6 cases and non-functioning tumor in one case. There was no significant difference in the operation time between right and left, men and women, primary aldosteronism and Cushing syndrome. The blood loss decreased with training. There were no severe complications during and after the operation. The weight of the resected adrenal glands increased. The blood loss decreased significantly compared with the open surgery. Transperitoneal laparoscopic adrenalectomy is becoming the safe and standard surgery for the adrenal gland tumor, and the number of suitable cases for this procedure is expected to increase in the future.

Abstract
Small cell carcinoma (SCC) occurs mostly in the lung, and in some patients is accompanied by production of ectopic hormones. Small cell carcinoma of the head and neck is very rare. We report 4 patients with SCC of the head and neck (larynx, tonsil, maxillary sinus, and parotid gland). The patient with SCC of the maxillary sinus demonstrated a high level of plasma serotonin and overexpression of parathyroid hormone; however, he did not show any related symptoms. The patient with SCC of the tonsil showed the syndrome of inappropriate secretion of antidiuretic hormone associated with antidiuretic hormone hyperproduction at the terminal stage. In the literature, 16 patients with SCC of the head and neck with ectopic hormone production have been reported. Antidiuretic hormone and adrenocorticotropic hormone were the hormones that caused clinical symptoms (paraneoplastic syndromes). We believe that the evaluation of hormonal syndromes is valuable for diagnosis and treatment.

Abstract
A new simple method for classifying genes is proposed based on Klastorin's method. This method classifies genes into monophyletic groups which are made distinct from each other by evolutionary changes. The method is applicable as long as the phylogenetic tree of genes is obtained. There is a fast algorithm for obtaining the classification. A bootstrap test of a classification is also presented. As an example, we classified opsin genes. The classification obtained by this method is the same as the previous classification based on the function of opsins.

Abstract
A combined data set of DNA sequences (6021 bp) from five protein-coding genes of the chloroplast genome (rbcL, atpB, psaA, psaB, and psbC genes) were analyzed for 42 strains representing 30 species of the colonial Volvocales (Volvox and its relatives) and 5 related species of green algae to deduce robust phylogenetic relationships within the colonial green flagellates. The 4-celled family Tetrabaenaceae was robustly resolved as the most basal group within the colonial Volvocales. The sequence data also suggested that all five volvocacean genera with 32 or more cells in a vegetative colony (all four of the anisogamous/oogamous genera, Eudorina, Platydorina, Pleodorina, and Volvox, plus the isogamous genus Yamagishiella) constituted a large monophyletic group, in which 2 Pleodorina species were positioned distally to 3 species of Volvox. Therefore, most of the evolution of the colonial Volvocales appears to constitute a gradual progression in colonial complexity and in types of sexual reproduction, as in the traditional volvocine lineage hypothesis, although reverse evolution must be considered for the origin of certain species of Pleodorina. Data presented here also provide robust support for a monophyletic family Goniaceae consisting of two genera: Gonium and Astrephomene.

Abstract
TS-1 is an oral anticancer drug that produces biochemical modulation. TS-1 is composed of FT (tegafur), CDHP (gimestat, which inhibits 5-FU degradation enzyme), and Oxo (otastat potassium, which reduces 5-FU gastrointestinal toxicities), in a molar ratio of 1:0.4:1. We administered TS-1 to a 68-year-old female gastric cancer patient, after distal gastrectomy (Stage IV, cur C). As a result of abdominal CT, the diameter of metastatic lymph node increased before and after surgery, and before TS-1 (45 x 35 mm), but it was reduced after 1 course of TS-1 (37 x 25 mm), 2 courses of TS-1 (35 x 20 mm), 3 courses of TS-1 (30 x 20 mm), 4 courses of TS-1 (30 x 20 mm), and 6 months after 4 courses of TS-1 (20 x 20 mm). The reduction rate is 74.6%. The value of CA125 was reduced 74.4 to 8.6 after TS-1. Anorexia and back pain, which occurred after operation, disappeared after TS-1. There was no side effect over grade 3.

Abstract
Vascular endothelial growth factor (VEGF) has been identified as the substance that increases the permeability and proliferation of vascular endothelial cells. We examined the clinical significance of VEGF expression in 60 head and neck squamous cell carcinomas using the methods of Western blot, immunohistochemistry, and reverse transcriptase-polymerase chain reaction (RT-PCR), comparatively, and analysed the relationship between VEGF status in Western blot and tumour size, lymph-node status, histologic grade and disease-free survival (DFS) rate. Western blot analysis revealed high VEGF expressors (tumour/normal tissue density >/= 3-fold) in 26 patients (43%) and low VEGF expressors (< 3-fold) in 34 patients (57%). The results of the Western blot analysis correlated significantly with those of the RT-PCR (P = 0.00007) or immunohistochemistry (P = 0. 00006). High VEGF expressors are associated with the progression of lymph-node spread (P = 0.0009), which are correlated with poor DFS. The 2-year DFS rate of high VEGF expressors (30%) was significantly lower than that of low VEGF expressors (78%) (P = 0.0008). Multivariate analysis showed VEGF expression and stage were independent predictors for the DFS (P = 0.045 and 0.041, respectively). VEGF expression may play an important role in progression of HNSCC.

Abstract
A member of the tumor necrosis factor (TNF) superfamily, human TNFSF14 (hTNFSF14)/HVEM-L (herpes virus entry mediator ligand) was isolated as a cellular ligand for HVEM/TR2 and human lymphotoxin beta receptor (LTbetaR). TNFSF14 induces apoptosis and suppresses tumor formation. We have isolated a cDNA clone for a mouse homologue of hTNFSF14 by signal sequence trap (SST) screening which we recently developed. The deduced amino acid sequence of the mouse TNFSF14 (mTNFSF14) cDNA comprised 239 amino acid residues and was 77% identical to the hTNFSF14 protein. In Northern blot analysis, 2.1 kb and 4.2kb mTNFSF14 transcripts were detected in spleen and lung, and in heart, respectively. Fluorescence in situ hybridization analysis localized the mTNFSF14 gene Tnfsf14 to chromosome 17 which is tightly linked with Tnf, Lta, and Ltb.

Abstract
We previously established a high-efficiency, retrovirus-mediated expression cloning method. Using this system, we now have developed an expression cloning method (FL-REX; fluorescence localization-based retrovirus-mediated expression cloning) in which cDNAs can be isolated based on the subcellular localization of their protein products. Complementary DNAs generated from mRNA using random hexamers were fused to the cDNA of green fluorescent protein (GFP) in the pMX retrovirus vector. The resulting cDNA-GFP fusion library was transfected into retrovirus-packaging cells, and the derived retroviruses were used to infect NIH 3T3 cells. Infected cells then were screened to identify cDNAs of interest through the subcellular localization of the GFP-fusion products. Using FL-REX, we have identified 25 cDNAs, most of which showed reasonable subcellular localization as GFP-fusion proteins, indicating that FL-REX is useful for identification of proteins that show specific intracellular localization.

Tongue squamous cell carcinoma makes up a large percentage of head and neck cancers, and the incidence among young patients is increasing. The aim of this study was to reveal the correlation between cyclin D1 (CCND1) expression and clinical and histologic features. We performed an immunohistochemical study on the level of CCND1 expression in tumor specimens obtained from 94 patients with tongue squamous cell carcinoma. The relationship between the expression and the following features such as age, sex, smoking and alcohol intake history, T, N, histologic grade, and multiple primary cancer was analyzed. Eighteen patients (19%) showed CCND1 overexpression (tumor cell nuclei positivity >/=50%). The 5-year survival rate of high CCND1 expressors was 39%, which was significantly poor (p=0.04). N classification correlated with CCND1 expression. CCND1 overexpression is associated with poor survival associated with progression of lymph node spread in patients with tongue squamous cell carcinomas. CCND1 expression may be a useful biologic marker for prognosis.

Abstract
Ascites due to carcinomatous dissemination is a severe problem for end-stage cancer patients. We attempted treating patients on an outpatient basis with the administration of low-dose CDDP-i.p. and reinfusion of ultrafiltrated and concentrated ascites. From 1995, we performed this therapy on 16 patients with concentrated ascites 6-8 fold and reinfusion, combined with low-dose CDDP-i.p. and drip infusion of 5-FU intravenously. The ascitic fluid was significantly decreased after treatment in 8 patients, and 2 patients had lasting low concentrations of CA 125. CA 125 decreased in 83.3% of patients, who tended to have extended survival times after remarkable ascites pooling and treatment with low-dose CDDP-i.p. and reinfusion therapy. This treatment is a useful cant method for decreasing ascites and improving QOL.

Abstract
Signal transducers and activators of transcription (STATs) play key roles in growth factor-mediated intracellular signal transduction. In the present study using a constitutively active STAT5 mutant, we show that STAT5 has pleiotropic functions regulating cell proliferation, differentiation and apoptosis in an IL-3-dependent Ba/F3 cell line. The mutant STAT5 possessed constitutive tyrosine phosphorylation and DNA binding activity, induced expression of bcl-xL and pim-1 in the absence of IL-3 in Ba/F3 cells, and rendered Ba/F3 cells factor-independent. Unexpectedly, IL-3 treatment of the factor-independent Ba/F3 cells expressing the constitutively active STAT5 resulted in apoptosis within 24 h, or differentiation followed by cell death. In these cells, mRNA expression of growth inhibitory genes downstream of STAT5 such as CIS, JAB/SOCS-1/SSI-1, and p21(WAF1/Cip1) was highly induced, correlating with prolonged hyper-phosphorylation of the mutant STAT5 after IL-3 stimulation. Of the STAT5-regulated genes, we found that constitutive expression of JAB/SOCS-1/SSI-1 was sufficient to induce apoptosis of Ba/F3 cells, while p21(WAF1/Cip1) could induce differentiation of these cells. In contrast, constitutive expression of pim-1 was sufficient to induce IL-3-independent growth of Ba/F3 cells. These findings suggest that a single transcription factor regulates cell fate by varying the intensity and duration of the expression of a set of target genes.

Abstract
BACKGROUND Hypopharyngeal cancer is closely associated with smoking, drinking, and malnutrition. Recent findings reveal that carcinogenesis depends on genetic aberrations. MATERIALS AND METHODS Eighty-one patients with hypopharyngeal cancer were analyzed for p53, CCND1, and p27, and 72 patients were analyzed for p21, immunohistochemically. RESULTS p53 overexpression was found in 70%, CCND1 in 17%, p21 in 29%, and p27 in 32%. The low intensity of p27 expression correlated with poor prognosis, but the level of expression of p53, CCND1, and p21 did not. CONCLUSION The immunohistochemical analysis of p27 provides a possible tool in determining the prognosis of patients with hypopharyngeal cancer.

Abstract
A 62-year-old Japanese man with hepatitis B virus-related liver cirrhosis revealed alpha-fetoprotein (AFP) elevation. Dynamic computed tomography, taken at this time, showed a liver tumor in the anterior segment. As the patient refused any further medical treatment, he was observed in an outpatient clinic. The size of the tumor reduced and the serum level of AFP decreased gradually without any treatment. Twelve months after the initial diagnosis, the tumor could not be detected by computed tomography (CT) scan, and the level of AFP had declined to the normal range. Blood supply is essential for tumor growth and an arterioportal shunt near the tumor may change the dynamics of blood flow to the tumor. The shunt found in this patient was thought to be one of the causative factors leading to regression, but it could not be denied that immunological mechanisms may have played an important role in the spontaneous regression of hepatocellular carcinoma.

Abstract
The amount and pattern of DNA polymorphism can give useful information on the maintenance mechanism of genetic variation at the DNA level. In this note we have shown the amount and pattern of DNA polymorphism expected under the neutral theory. The amount of DNA polymorphism can be estimated from the average number of nucleotide differences per site, the proportion of segregating sites, and so on. We have shown how to estimate theta from these quantities, where theta = 4Nv, N is the effective population size and v is the mutation rate per site per generation. We have also shown the expectations of the nucleotide variation within and between allelic classes.
