Abstract
Background Acromegaly is a rare disease caused by growth hormone (GH) hypersecretion caused by a pituitary neuroendocrine tumor (PitNET). However, some acromegaly patients show normal GH levels, and they can be a pitfall in clinical diagnosis. Moreover, rarely, synchronous true double or multiple PitNETs are encountered. Moreover, these PitNETs increase the risk of a left lesion during surgical exploration. Case Description The patient, who was a 73-year-old female, was referred to our hospital with a chief complaint of headache. Assessment of basal anterior pituitary function revealed a slightly high level of insulin-like growth factor-1 (IGF-1) (standard deviation, 2.4), and her physical findings exhibited mild acromegalic features. The endocrine evaluation confirmed acromegaly and magnetic resonance imaging (MRI) showed a macro PitNET with suprasellar extension. Endoscopic endonasal surgery (EES) was performed to remove the macro PitNET. Although postoperative MRI showed complete removal of the macro PitNET, endocrinological testing indicated no improvement in GH or IGF-1 excess. Pathological examination of the surgical specimen revealed a gonadotropic PitNET. Therefore, we repeated the MRI scan and found a micro PitNET in the thin left normal pituitary gland. A second EES was successfully performed to remove the micro PitNET completely, and both endocrinological and pathological examinations confirmed that the disease was cured. Conclusion Diagnosing acromegaly with low GH levels requires close monitoring. Double PitNETs are relatively rare and can cause incomplete remission of functional PitNETs.

Abstract
We present the case of an 85-year-old male patient diagnosed with human herpesvirus 8 (HHV8)-negative effusion-based lymphoma (EBL) that developed from long-lasting pleural effusion (PE) induced by dasatinib treatment for chronic myeloid leukemia (CML). After the onset of this disorder, dasatinib treatment was discontinued and drainage was performed to regress the effusion. The major molecular response (MMR) was thus lost. The patient did not tolerate nilotinib treatment, but bosutinib was successful in restoring MMR. During these clinical courses, the patient suffered from a recurrence of EBL, which was treated with rituximab-based chemotherapy. The PE sample just before the 3rd cycle of chemotherapy revealed the proliferation of CD57-positive T cells, along with the disappearance of lymphoma cells. Anti-tumor immunity may have been activated following the immunochemotherapy in the undisturbed immunological environment when both EBL and CML almost regressed. After four cycles of R-CVP therapy, the patient has been in remission for 16 months and no longer requires drainage.

Abstract
Tumor flare reaction (TFR) is a unique immune-mediated tumor recognition phenomenon
presenting as rapid enlargement of the tumor, which mimics disease progression, developing
in the early stage of treatment using immunomodulatory drugs or immune checkpoint
inhibitors. A 59-year-old man with follicular lymphoma had residual tumor burden in the
left hilar lymph nodes after R-CHOP therapy, and received lenalidomide and rituximab
(R2) therapy. He developed respiratory distress on day 11 of R2
therapy. Chest X-ray and CT demonstrated left lung atelectasis due to left hilar lymph
node swelling. We performed transbronchial lung biopsy on day 20 of R2 therapy.
The biopsied left bronchus tissue exhibited extensive necrosis, which had a B-cell
phenotype consistent with that of follicular lymphoma. Neither NK cells nor cytotoxic T
cells were detected. It was unclear whether the immune effector cells disappeared at the
time of transbronchial lung biopsy. Atelectasis in our patient improved by continuing
R2 therapy beyond TFR.

Abstract
Immune checkpoint inhibitors (ICIs), despite their ability to potentiate antitumor T-cell
responses, may cause various immune-related adverse events. Most cases of thrombocytopenia
induced by ICIs have revealed a pathophysiologic mechanism of immune thrombocytopenia with
increased platelet destruction and preserved megakaryocytes. Acquired amegakaryocytic
thrombocytopenic purpura (AATP) is an unusual disorder characterized by thrombocytopenia
with markedly diminished bone marrow megakaryocytes in the presence of otherwise normal
hematopoiesis. AATP caused by ICIs has not been reported on. Herein, we present the case
of a 79-year-old man diagnosed with squamous cell carcinoma of the lung who developed AATP
after two courses of durvalumab, a drug targeting programmed death-ligand 1. Two weeks
after the second cycle, his platelet count decreased to 2.1 × 104/μL. After the
patient underwent platelet transfusion, his platelet count increased to 8.1 ×
104/μL the next day but subsequently decreased repeatedly even after the ICI
was discontinued. Six weeks after the second cycle, he developed interstitial pneumonia
and was administered prednisolone (50 mg/day). However, thrombocytopenia did not improve.
Bone marrow biopsy showed scarce megakaryocytes (< 1 megakaryocyte/10 high-power
fields) with preservation of myeloid and erythroid series. Myelodysplasia, myelofibrosis,
or metastatic lesions were not observed. Cytogenetic analysis showed a normal male
karyotype of 46XY. Hence, the patient received eltrombopag, a thrombopoietin receptor
agonist, and his platelet count subsequently improved. After recovery, bone marrow
aspiration revealed a normal number of megakaryocytes. AATP is rarely the type of
thrombocytopenia induced by ICIs and may be successfully treated with thrombopoietin
receptor agonists.

Abstract
Abstract:The purpose of this study was to disclose which types of cancer and how many persons with cancer were detected among the AMHTS examinees of our AMHTS center by using the hospital information retrieval system, and to study the relationship between cancer and the number of examinees, checkup intervals, and frequency in AMHTS. The examinees who had checkups more than twice were divided into three groups based on their checkup intervals: within one year, one to two years, and over two years. The relationship between cancer ratios and checkup intervals was evaluated in each group of examinees. In those having checkups within one year and from one to two years the cancer rate was 2.9 patients per 1,000 persons. However, in those having checkups after a two-year period or longer, the cancer rate was 4.3, clearly greater than the rate of the other two groups.

Abstract
A 6 2-year-old woman visited our hospital with a complaint of anal bleeding and was diagnosed with rectal cancer. She underwent low anterior resection and D3 lymphadenectomy. The pathological diagnosis was shown as follows: Ra, Circ, type 2, por1, pSS, ly3, v1, pN2, pStage III b, and KRAS wild type. UFT/UZEL with polysaccharide K(PSK)was initiated as adjuvant chemotherapy after the operation. However, multiple liver metastases were found on CT after 3 courses of UFT/UZEL with PSK, and pathological reexamination revealed that the primary tumor was a neuroendocrine carcinoma. She underwent chemotherapy with CBDCA combined with CPT-11, but bone marrow suppression was observed after 4 courses of the treatment. As second-line chemotherapy, FOLFOX4 plus panitumumab(Pmab)was administered. Although the disease remained stable through 10 courses of FOLFOX4 plus Pmab, Grade 3 peripheral neuropathy was observed. Hence, FOLFIRI plus bevacizumab(Bmab)was administered as third-line chemotherapy. Twenty-eight courses of FOLFIRI plus Bmab were administered, and transcatheter arterial chemoembolization(TACE)was performed during chemotherapy. However, her general condition worsened after the therapies, and she died 2 years 3 months after the initial chemotherapy.

Abstract
BACKGROUND Salivary duct carcinoma (SDC) is a highly aggressive disease which often metastasizes to distant sites, and there is no established standard therapy for this systemic disease. Given that SDC is biologically similar to breast and prostate cancer, anti-androgenic receptor (AR) and anti-human epidermal growth factor receptor 2 (HER2) therapies have the potential to exert effects, not only on patients with breast and prostate cancer but also on those with SDC. METHODS The expression levels of HER2, epidermal growth factor receptor (EGFR), Ki-67, and AR were assessed in 32 patients with SDC, and their correlations with overall survival (OS) and disease-free survival (DFS) were analyzed retrospectively. SDC was classified into five subtypes using a method similar to that used for breast cancer. RESULTS Anti-AR, HER2, and EGFR were positive in 23 (71.9 %), 14 (43.8 %), and 26 (81.3 %) cases, respectively. One or more of these 3 factors were positive in 30 (93.8 %) cases. The Ki-67 labeling index was greater than 15 % in all cases. While molecular status did not correlate with OS, EGFR and AR positivity were significantly associated with DFS in univariate analysis. Multivariate analysis revealed that EGFR was the only independent predictor of DFS. CONCLUSIONS The statuses of some molecules are useful to predict DFS in patients with SDC. Ki-67 overexpression suggests that cytotoxic agents are effective for SDC. Since the majority of SDCs express AR, HER2, and/or EGFR, assessing and targeting these molecules are promising strategies to improve the prognosis of unresectable, metastatic or recurrent SDC, and a classification system according to the molecular expression status may be useful to select appropriate therapy.

Abstract
BACKGROUND AND AIMS The most effective treatment would be neoadjuvant chemoradiotherapy (NACRT) plus surgery with three-field lymphadenectomy, if tolerability and complications are acceptable. The aim of this prospective study was to evaluate the tolerability of NACRT+ systematic three-field lymphadenectomy. METHODS A total of 127 cases of advanced esophageal carcinoma were objected, among which 32 had NACRT, being the cases suspected to cT3-T4 or, < cT3 with multiple lymph node metastasis. ≥ T2 of 95 cases were treated by surgery alone (NACRT [-] case). The effect of NACRT was evaluated by histological examination and corrected with the clinicopathologic factors, including postoperative prognosis. After reports JCOG9907, we treated eight cases with neoadjuvant chemotherapy at stages II and III. We examined Musashi-1 staining for these eight cases. RESULTS Histological good response to NACRT group showed good prognosis. Lymph node metastasis is a predictive factor for prognosis. In this additional study, Musashi-1 was positive after neoadjuvant chemotherapy in three cases. The histological response was grade 1 in all of them and recurrence was observed within a short period of time. Two cases of grade 3 were negative staining to Musashi-1 and showed no recurrence. CONCLUSIONS This study shows that NACRT plus surgery with three-field lymphadenectomy is a feasible therapeutic approach for the cases with multiple lymph node metastases. Prognosis was significantly better in cases with marked histological improvement. It is important to find the predictive factors of histological improvement. Musashi-1 might be a candidate maker for histological response and prognosis, and further studies are needed to prove it.

Abstract
Gastric neuroendocrine carcinomas are rare and have a poor prognosis, and the diagnostic criteria for this disease have recently changed. We herein report a case of sporadic gastric neuroendocrine carcinoma. A 75-year-old man was referred to our hospital with epigastric pain. Endoscopic examination revealed a localized ulcerative lesion (diameter, 4 cm) at the upper stomach. The diagnosis on biopsy was neuroendocrine carcinoma. Total gastrectomy with D2 lymphadenectomy, splenectomy, and cholecystectomy was performed. Pathologically, the tumor infiltrated the subserosal layer, and 6/49 lymph nodes were involved. The tumor was uniform in shape and arranged in a rosette-like structure to form solid nests, with medium-sized, round-to-cuboid-shaped tumor cells and intense mitosis 46/10 HPF. It was positive for synaptophysin and chromogranin A, and the Ki-67 labeling index was 70-80%. The diagnosis of neuroendocrine carcinoma was made according to the WHO 2010 criteria. The patient was followed up for three years without recurrence.

Abstract
We report 2 cases of ileocecal carcinoid with review of the literature recently reported in Japan. Both cases were diagnosed as carcinoid by colonoscopic biopsy after ileocecal tumors had been pointed out by computed tomography. We performed curative operation with lymph node dissection. Since multiple lymph node metastases were shown in both cases pathologically, they were closely followed after surgery, but no recurrence has been shown. Since SSTR2a stain was strongly positive in both cases, octreotide, the effectiveness of which was verified in the PROMID study might be administered if necessary. As ileocecal carcinoid has a tendency to metastasize to other organs, careful surveillance by colonoscopy and early detection are required. Furthermore, development of effective drugs following octreotide and further investigation including biological and histopathological analysis of neuroendocrine tumors including carcinoid are necessary.

Abstract
Carcinoids were first reported approximately 100 years ago and proposed to be neuroendocrine tumors of hormonal origin some 50 years later. The first edition of the WHO classification included neuroendocrine tumors of the digestive organs and pancreas, but thereafter it was pointed that neuroendocrine cells are distributed throughout the body and thus that carcinoids occur in various other organs. The most recent edition of the WHO classification takes into account the occurrence of neuroendocrine tumors throughout the body. In addition, carcinoids were originally thought to be variants of a benign tumor type with a low malignancy rate, but thereafter metastases were observed. The term "neuroendocrine tumors" is now preferred instead of "carcinoids," and the malignant potential of such tumors is recognized. This paper reviews the classification and treatment of gastroenteropancreatic neuroendocrine tumors.

Abstract
Squamous cell carcinoma of the esophagus with cancer invasion beyond the muscularis mucosae is known to have lymph node metastasis and lymphatic or blood vessel invasion compared with intramucosal carcinoma. In submucosal and T2-3 carcinoma, lymph node and lymphatic/vascular involvement are shown more frequently, leading to a poor prognosis. Therefore, we examined proliferative activity of esophageal squamous cell carcinoma including early carcinoma in relation to clinicopathological findings. 77 cases of esophageal squamous cell carcinoma, including 23 cases of mucosal carcinoma (Tis+T1a), 35 cases of submucosal carcinoma (T1b) and 19 cases of advanced invasive carcinoma (T2+T3) undergoing surgical resection without preoperative treatment were studied using monoclonal antibody MIB-1 for Ki-67 antigen immunohistochemically, and the labeling index (LI) was calculated. The LI of MIB-1 positive nuclei correlated with the depth of cancer invasion was significantly increased in the cancer invading beyond the musculais mucosae. The LI at the invasive tip was significantly higher than that at the core of differentiated carcinoma. The LI values at both invasive tip and core of poorly differentiated carcinoma were higher than those of differentiated carcinoma with significant difference. The LI at the invasive tip of the carcinoma with lymph node metastasis or lymphatic invasion was significantly higher than that without them. Proliferative activities of esophageal cancer cell, immunostaining with MIB-1, had correlations to depth of tumor invasion, differentiation, lymph node metastasis and lymphatic invasion with significant difference. But if invading deeper than m3, the proliferative activity did not increase anymore.

Abstract
We performed single cell polymerase chain reaction (PCR) amplification of the t (14 ; 18) translocation from paraffin embedded sections in a case of follicular lymphoma (FL) with subsequent development of Hodgkin lymphoma (HL). The lymphoma cells of FL were positive for CD20, CD10 and BCL-2, and negative for CD3, CD30 and CD15. Hodgkin and Reed-Sternberg (HRS) cells of HL were positive for CD20, CD30 and CD15, and negative for CD3 and CD10. EBER-1 RNA in situ hybridization failed to stain with both lymphomas. HRS cells manipulated and FL cells micro-shaved from individual neoplastic follicles were subjected to single-cell PCR. The t (14 ; 18) translocation, a chimeric DNA containing portions of the bcl-2 and the immunoglobulin heavy chain (IgH) genes, was amplified from four of 27 isolated HRS cells and two individual FL follicles. All t (14 ; 18) PCRs yielded products of the same size, and an identical nucleotide sequence including the t (14 ; 18) translocation was found in both FL and HRS samples. Thus, the data demonstrate the common clonal origin of FL cells and HRS cells in subsequent HL, and that both FL and HL were derived from germinal center B cells with the t (14 ; 18) translocation.

Abstract
Glucose transporter-1 (GLUT-1) expression was immunohistochemically analysed in a total of 268 cases of thyroid gland disease, including 129 cases of papillary carcinoma (PC), 60 cases of follicular carcinoma (FC), 57 cases of follicular adenoma, and 22 cases of adenomatous goitre. Seventy-one percent (91/129) of PC cases showed GLUT-1 expression, semi-quantitatively evaluated as: +, 21 cases (16%); 2+, 37 cases (29%); 3+, 33 cases (26%); and negative, 38 cases (29%). These positive cases were divided into two groups: 'membrane-like' pattern in 24 cases (19%), and 'cytoplasm-predominance' pattern in 67 cases (52%). GLUT-1 expression was observed in 5% (3/60) of FC cases, but all follicular adenomas and adenomatous goitres were negative for GLUT-1 (PC vs. FC, p<0.0001). Membrane-like expression was observed more frequently in non-organ-confined PCs (pT4) than in organ-confined PCs (pT1, 2, and 3) (p=0.0056). Seventy-five percent (18/24) of PC cases showing membrane-like expression were non-organ-confined. The membrane-like pattern was observed more frequently in PCs with lymph node (LN) metastasis compared to those without (p=0.0036). Ninety-two percent (22/24) of PC cases showing the membrane-like pattern were not organ-confined. Semi-quantitative analysis of glut-1 mRNA by RT-PCR showed a tendency toward higher expression in PCs compared to FCs, follicular adenomas and adenomatous goitres, and the mRNA expression in PCs with a membrane-like pattern was higher than those showing cytoplasm-predominance. We concluded that: 1) GLUT-1 is immunohistochemically useful in distinguishing PC from FC and benign diseases; 2) GLUT-1 may play an important role in the advancement of PC and LN metastasis, and its membrane-like expression is of more clinical significance than the cytoplasm-predominance pattern; and 3) glut-1 mRNA expression corresponds with the immunohistochemical expression profile.

Abstract
Schwannoma arising from the kidney is a rare benign tumor, with only 20 cases reported in the English literature. We encountered a histopathologically typical Schwannoma of the kidney in a 39-year-old woman, which was characterized by marked calcification. Radical nephrectomy was performed under the diagnosis of renal cell carcinoma. The 21 reported cases of schwannoma of the kidney, including the present case, are reviewed in detail.

Abstract
Carbohydrate antigens and E-selectin play important roles in the invasion and metastasis of cancers. We examined the expression of these antigens and their ligand protein, E-selectin, in urothelial carcinomas to evaluate whether their staining is correlated with the grade and stage of cancer. We studied the expression of carbohydrate antigens (type 1 and type 2 blood-group antigens) and E-selectin in urothelial carcinomas of the renal pelvis, ureter, and urinary bladder in 52 patients by staining SSEA-1 (LeX), sialyl LeX (sLeX), DU-PAN-2, CA19-9, and E-selectin with 5 different monoclonal antibodies (MAbs) to evaluate whether their staining correlated with cancer grade and stage. The differences between organs with regard to the degree of expression of these antigens were not evident. Type 2 antigens (SSEA-1 and sialyl LeX) are frequently expressed in the tumor cells regardless of atypical grade. The expression level of type 1 antigens (DU-PAN-2 and CA19-9) is lower than that of type 2 antigens. However, the presence of DU-PAN-2 tends to correlate with the grade of atypia; however, that of CA19-9 is inversely proportional to the grade of atypia. The lack of CA19-9 and appearance of DU-PAN-2 in urothelial carcinoma implies a high malignant potential. The expression of E-selectin can be correlated with stage and grade of tumor atypia. Type 2 antigen and E-selectin may be involved in tumor invasion and metastasis.

Abstract
Serum tumor markers are useful for detection and diagnosis of cancer. Recent advances in cellular and molecular biology have developed procedures of immunohistochemistry including high sensitivity staining and epitope retrieval. Using the immunohistochemical analyses, we can detect various tumor markers, i.e., not only serum tumor markers (serum protein, carbohydrates), but also cellular skeletons, lymphocyte surface antigens, cytoplasmic markers, oncogene products and cell adhesion molecules. This article focuses on several immunohistochemical tumor markers. Carcinoembryonic antigen(CEA) is one of the good markers of colorectal cancer. Recent studies have demonstrated that CEA may function as a metastatic potentiator by different pathway, such as modulation of immune responses, facilitation of intercellular adhesion and cellular migration. CA19-9 (sialyl Le antigen), a member of a family of high molecular weight glycoproteins, was originally described as a gastrointestinal- and pancreatic-specific tumor marker. Recent studies have demonstrated that sialyl Le is a ligand for E-selectin and may play an important role in tumor metastasis. Stromal immunoreactivities of CEA or CA19-9 were correlated with lymph node metastasis and/or vascular invasion. p53 is one of the most important tumor suppressor genes, and the p53 gene product is known to regulate cell growth and proliferation. Mutation of the p53 gene can be detected immunohistochemically as overexpression of its protein in the nucleus. Diffuse p53 immunoreactivity was a histological marker of adenocarcinoma. In conclusion, immunohistochemical tumor markers are useful for histopathological diagnosis and can be prognostic predictors of cancer.

Abstract
It is unclear how the cytokine network contributes to the expression of granulocyte-macrophage colony-stimulating factor (GM-CSF) in non-small cell lung cancer (NSCLC). We examined the gene expression of GM-CSF and interleukin (IL)-10 in 78 surgical specimens and 16 xenografts of NSCLC by reverse transcription-polymerase chain reaction. Forty-four of the 78 (56.4%) surgical specimens and 11 of the 16 (68.8%) xenografts of NSCLC showed GM-CSF gene expression. Forty-one of the 44 (93.2%) GM-CSF-positive NSCLC specimens showed IL-10 expression, and GM-CSF expression was significantly correlated with IL-10 expression (p < 0.0171, Mann-Whitney's U-test). These results suggested that IL-10 is one of the cytokines up-regulating the GM-CSF expression in NSCLC.

Abstract
We examined the effects of suppressing multidrug resistance-associated protein 1 (MRP1) gene expression in a human glioma cell line U87MG. Hammerhead ribozymes, designed to cleave MRP1 mRNA (alphaMRP1-Rz), were transfected into the U87MG cells. The U87MG/alphaMRP1-Rz cells were significantly sensitive to nitrosourea (ACNU) and doxorubicin (DOX) compared with the U87MG cells (p<0.01 and p<0.05, respectively, unpaired t-test). There was no significant difference in the expression of other human genes between the U87MG/alphaMRP1-Rz and controls by cDNA array. The hammerhead ribozyme-mediated specific suppression of MRP1 was sufficient to reverse the resistance of ACNU and DOX in the human glioma cell line.

Abstract
BACKGROUND Hyper-immunoglobulin E (IgE) syndrome is a complex immune deficiency characterized by chronic eczematous dermatitis, recurrent staphylococcal infections, pneumatoceles, reduced neutrophil chemotaxis, and variably impaired T cell function. Although decreased interferon-gamma (IFN-gamma) production in patients with hyper-IgE syndrome is pointed out and known as a cause of reduced neutrophil chemotaxis, precise mechanism of their inadequate production of IFN-gamma remains unknown. To elucidate the pathogenesis of the defective production of IFN-gamma in patients with hyper-IgE syndrome, we assessed the in vitro production and secretion of IFN-gamma by peripheral blood mononuclear cells (PBMCs) from patients with hyper-IgE syndrome. METHODS Chemotaxis of neutrophils, mRNA levels of several cytokines, intracellular production and extracellular secretion of IFN-gamma, interleukin-2 (IL-2), and IL-4 by PBMCs from three patients with hyper-IgE syndrome were determined. RESULTS The transcription of IFN-gamma mRNA and the production of its protein molecules progressed normally. However, selective insufficiency in the secretion of IFN-gamma molecules was found in patients with hyper-IgE syndrome. Confocal laser scanning microscopy clearly demonstrated the accumulation of IFN-gamma in patients with hyper-IgE syndrome. CONCLUSION We demonstrated that there was a selective insufficiency in the secretion of IFN-gamma in patients with hyper-IgE syndrome. We hope that this fact would offer a new paradigm for understanding this disease.

Abstract
A-25-year-old man was admitted because of a painless tumor of the scrotum. The patient denied a history of exogenous material injection and trauma in the scrotum. Physical and radiological examination revealed a mass in the scrotum, and blood laboratory tests showed no significant findings except for mild eosinophilia (5.6%). Resection of the mass was performed. The mass was isolated and located in the subcutaneous tissue of the scrotum. The mass was rectangular and symmetrical, and measured 65 x 45 x 15 mm. Histologically, the mass was composed of adipose tissue with fibrosis. Many epithelioid granulomas with multinucleated giant cells of foreign body and Langhans' types and heavy infiltrates of lymphocytes and eosinophils were recognized. Characteristically, the lesion showed broad coagulative and lytic necrosis. Congestion and edema suggestive of ischemia were seen in some areas. Special stains for acid-fast bacteria, gram-positive bacteria and fungi failed to detect any microorganisms. Polymerase chain reaction for mycobacterium tuberculosis revealed no reaction products. Immunohistochemically, the majority of lymphocytes were CD45RO-positive T cells, and S-100 protein-positive cells and CD68-positive macrophages were scattered in small amounts. The appearances were typical for sclerosing lipogranuloma except for the necrosis. Although the pathological mechanism of the broad necrosis is unclear, the necrosis might be the result of ischemia. Our case suggests that primary sclerosing lipogranuloma of the scrotum might show broad necrosis, and that T-cell-mediated immune response might play a part in the formation of lipogranuloma.

Abstract
The 189 amino acid isoform of vascular endothelial growth factor (VEGF189) has been shown to be more strongly associated with the cell membrane than other isoforms of human VEGF (VEGF121, VEGF165). To analyze the biological activities of these VEGF isoforms on tumor growth, we transfected human VEGF121, VEGF165 or VEGF189 cDNA into the human colon cancer cell line SW-480, and established several clones overexpressing these VEGF isoforms. The total amounts of VEGF protein in the culture supernatants of the VEGF189-transfectants were less than those of VEGF121 and VEGF165-transfectants. These transfectants showed no significant differences in growth in culture. Nevertheless, the rate of in vivo tumor growth of VEGF189-transfectants was faster than or equivalent to that of VEGF121-transfectants, while the VEGF165-transfectant showed the greatest enhancement of tumor growth. The protein levels of VEGF were markedly increased only in the VEGF189-transfectants cultured in the presence of heparin. The enhanced in vivo tumor growth of VEGF189-transfectants can be partly explained by the cell-associated features of VEGF189 molecules. The VEGF189 molecule, which is strongly bound to the cell surface, has unique properties and high potential in local angiogenesis and tumor growth in the cancer inductive microenvironment.

Abstract
BACKGROUND Cell-retained isoforms of vascular endothelial growth factor A (VEGF-A) have been reported to play an essential role in tumor progression through stromal neovascularization in malignant solid tumors. While more than 95% of nonsmall cell lung carcinoma (NSCLC) expresses cell-retained VEGF-A isoform, the clinicopathologic implications of neuropilin (NRP), considered the specific receptor for limited types of VEGF-A isoform, are not well understood. METHODS The authors examined NRP1 and NRP2 mRNA expression in 68 NSCLCs and 15 extraneoplastic tissues by a densitometry-assisted, semi-quantitative reverse transcription-polymerase chain reaction. The authors determined the distinct expression of NRPs using the expression level of NRPs relative by optical density to beta2-microglobulin. The authors also investigated VEGF-A isoforms, their receptors, and the clinical implications. Vascularity of NSCLC was morphologically estimated on sections immunostained with anti-CD34 antibody. RESULTS Eleven of 15 extraneoplastic specimens showed NRP1 expression (73.3%) and 8 showed NRP2 expression (53.3%). The expression level of NRP1 or NRP2 of neoplasmic tissue was higher than that of extraneoplastic tissues (P < 0.01, Mann-Whitney U test). Fifty-five and 44 NSCLCs expressed NRP1 and NRP2, respectively. Forty patients co-expressing NRP1 and NRP2 showed significantly poorer prognosis and increased vessel counts as compared to those 28 cases without co-expression (P < 0.05, log-rank test; P < 0.05, Mann-Whitney U test). CONCLUSIONS The co-expression of NRP1 and NRP2 genes is significantly correlated with tumor progression through neovascularization in NSCLC. These results suggest that both NRP1 and NRP2 are key molecules for stromal vascularization by cell-retained VEGF in NSCLC.

Abstract
We report a rare case of minute (5 mm x 4 mm) mixed ductal-endocrine carcinoma of the pancreas with predominant intraductal growth. A 34-year-old Japanese man was admitted because of elevated serum pancreatic enzymes. Endoscopic retrograde pancreatography revealed an unidentified material of 18 mm within the main pancreatic duct. Stone or parasite with acute pancreatitis was suspected clinically, and the biopsy revealed malignant cells positive for CA19-9, carcinoembryonic antigen (CEA) and synaptophysin. No apparent tumor was identified in the pancreas by various imaging techniques. Resection of pancreatic body and tail was performed. Grossly, the main pancreatic duct in the pancreatic body was occluded by as much as 20 mm. The pancreas had minute carcinoma of 5 mm x 4 mm just around the occluded main pancreatic duct. The tumor cells invaded the main pancreatic duct and spread within it as long as 20 mm. Histologically, the carcinoma had biphasic pattern; one was ductal carcinoma with tubular formations and another was carcinoma with neuroendocrine features. These two elements were admixed, and the ductal element comprised 30% while the endocrine element comprised 70%. The ductal element was immunoreactive for cytokeratins, CEA and CA19-9, while the endocrine element was immunoreactive for chromogranin A and synaptophysin. No immunoreactivity for pancreatic enzymes was noted. Ultrastructural observations showed dense core granules and no zymogen granules. Our case is unique clinically in that the tumor manifested as an intraductal material and no apparent tumor was found by imaging modalities, and pathologically in that the tumor was rare mixed ductal-endocrine carcinoma and the tumor was very small and mainly grew within the main pancreatic duct.

Abstract
Interleukin 10 (IL-10) is an immuno-suppressive cytokine produced by T-lymphocytes, and a regulatory molecule for angiogenesis in various cancers. We examined IL-10 gene expression in 53 colon cancer patients who underwent surgical resection. IL-10 gene expression was correlated with TSP1 and TSP2 gene expression (P=0.0049, P=0.0285). Colon cancer with IL-10 gene expression (19/53) showed significantly decreased venous involvement (P=0.0433). The mean vessel counts in the colon cancers with IL-10 gene expression were significantly lower than those without IL-10 gene expression (P<0.001). These results suggested that IL-10 stimulates angiostatic factor gene expression, and results in suppression of venous involvement.

Abstract
Angiogenesis plays an important role in growth and proliferation of cancer. Various angiogenic and angiostatic factors regulate angiogenesis. In this study, we examined gene expression of the angiopoietin family including angiopoietin 1 (Ang1) and angiopoietin 2 (Ang2) in 39 gliomas and 5 glioma-xenografts by RT-PCR. Ang1 and Ang2 genes were expressed in 54%, and 77% of gliomas, respectively. The expression of Ang1 was significantly correlated with the expression of Ang2. Both Ang1 and Ang2 were shown to be expressed in the glioma cells. Ang2 gene expression was correlated with VEGF gene expression. Angiopoietin molecules may synergistically cooperate in growth and vascularization in glioma.

Abstract
E-cadherin, the major intercellular adhesion molecule of epithelial cells, is important in determining the architecture of sarcomas, especially those showing epithelioid features. In addition to its role in cell adhesion, beta-catenin, a cadherin undercoat protein, has been shown to function as a downstream transcriptional activator of the Wnt/Wingless signaling pathway. In order to evaluate the significance of the cadherin cell adhesion system and the Wnt/Wingless signaling pathway in the morphogenesis and/or tumorigenesis of synovial sarcoma (a major type of sarcoma with epithelioid features), immunoreactivity for pan-cadherin, E-cadherin, and their undercoat proteins (alpha-, beta-,and gamma-catenins and p120) was evaluated in 15 synovial sarcomas. Immunoreactivity for pan-cadherin, E-cadherin, alpha-catenin, beta-catenin, and p120 was observed in all 15 specimens. Immunoreactivity for pan-cadherin was stronger than that for E-cadherin. Expression of gamma-catenin was detected in ten specimens. Although beta-catenin was observed only at the cell-cell boundaries in four specimens, it was present in the nucleus and cytoplasm and at the cell-cell boundaries in the other 11, suggesting constitutional activation of the Wnt/Wingless signaling pathway in synovial sarcoma. Direct sequencing for exon 3 of the beta-catenin gene, however, revealed no mutations in any of the 15 specimens. In conclusion, other types of cadherin besides E-cadherin, together with cadherin undercoat proteins, may play a role in cell adhesion in synovial sarcoma. Furthermore, mechanisms other than mutation of exon 3 of the beta-catenin gene may activate the Wnt/Wingless signaling pathway in this type of tumor.

Abstract
BACKGROUND Recently the pros and cons of limited surgery for small-sized peripheral non-small-cell lung cancers (PNSCLCs), such as omission of mediastinal dissection, etc., have been vigorously debated. We analyzed whether hilar/mediastinal lymph node metastases were present in 30 small-sized PNSCLCs. MATERIAL AND METHODS In the nine years from 1990 to 1998, 294 lung cancer patients underwent lobectomy or pneumonectomy combined with hilar/mediastinal dissection in the Tokai University Hospital. Thirty of these patients diagnosed as having cT1N0M0 PNSCLC with tumor diameters of 1.5 cm or less by computed tomography, are evaluated in this article. RESULTS The 30 PNSCLC patients consisted of 14 males and 16 females with a mean age of 61 +/- 9 years. Twenty six patients (87%) had no hilar nor mediastinal lymph node metastases (pN0), one patient (3%) had a hilar lymph node metastasis (pN1), and three patients (10%) had mediastinal lymph node metastases (pN2). CONCLUSIONS Mediastinal lymph node metastases were histologically observed in 3 (10%) of 30 PNSCLC patients with tumor diameters of 1.5 cm or less. Our results show that mediastinal dissection is still necessary even for small-sized lung cancers.

Abstract
OBJECTIVE intrauterine parvovirus B19 infection is related to non-immune hydrops fetalis, the pathogenesis of which is based on the strict tropism of B19 for erythroid precursor cells and the massive destruction of the infected erythroid cells, although the mechanism of beta19-induced cytotoxicity has not been studied in detail. The purpose of this study is to provide empirical evidence that beta19 induces apoptosis of erythroid cells both in vitro and ill vivo. METHODS we analysed culture cells infected in vitro by B19 and tissues of nine cases of hydrops fetalis caused by B19 intrauterine infection by histological and biological methods. RESULTS cells infected iil vitro by B19 showed nuclear changes characteristic of apoptosis by light microscopic examination and DNA extracted from the infected cells was fragmented. Electron microscopic examination showed the nuclei of infected cells contained crescent-shaped clumps of heterochromatin with increased density and double staining with anti-B1 9 antibody and terminal deoxynucleotidyl transferase (TdT)-mediated deoxyuridine triphosphate-digoxigenin nick-end labeling (TUNEL) confirmed apoptosis of individual cells. Tissues of cases of hydrops fetalis caused by B19 contained erythroid cells with nuclear inclusions and characteristic nuclear changes of apoptosis by light microscopy. The double-staining confirmed apoptosis of erythroid cells in the tissues. Immunohistochemical analysis with antibodies against cellular factors involved in apoptosis showed that caspase3, p53 and p21 were positive in infected cells.

Abstract
A 38-year-old woman presented with a mucosal gastric carcinoma measuring 0.7 x 0.5 cm and para-aortic lymph node metastasis. Radiographic and endoscopic studies showed a small depressed lesion on the anterior border of the gastric angle, which was classified as a type II c + III lesion. Histological examination of the biopsy specimen revealed a signet-ring cell carcinoma. Distal gastrectomy with wide lymph node excision was performed. Detailed study of the resected specimen revealed that the tumour was limited to the mucosa, but metastasized to both the perigastric and para-aortic lymph nodes. The patient received adjuvant immunochemotherapy postoperatively. However, multiple bone metastases developed at 3 years and she died 4 years after the operation.

Abstract
It has been suggested that changes in the micro circulatory system are related to the early production of acute gastric mucosal injury and inflammatory factors such as prostaglandins, histamine, etc., have been considered as contributing to the development of the injury. We assessed the permeability of the gastric mucosa in rats with ethanol-induced acute mucosal injury by measuring the leakage rate of 51chronium-ethylene-diamine-tetraacetic acid (51Cr-EDTA) into the gastric juice. Histamine concentrations in the gastric mucosa was measured by high performance liquid chromatography. The enterochromaffin-like (ECL) cell counts in the gastric mucosa was performed following histamine staining with an enzyme-labeled antibody, and the histamine released due to degranulation was observed. We also investigated the kinetics of endogenous histamine in the gastric mucosa. Five minutes after the administration of ethanol, an increase in permeability, an increase in histamine concentration, and a decrease in ECL cell count were found in the gastric mucosa. These results suggest that endogenous histamine in the gastric mucosa is closely related to the early development of acute gastric mucosal injury.

Abstract
Esophageal cancer has a poor prognosis because it is difficult to detect in its early stages and, even if an operation is possible, the postoperative quality of life is much impaired. An early diagnosis can lead to a good prognosis and enables treatment by endoscopic mucosal resection (EEMR), contributing to a postoperative good quality of life. As head and neck cancers are known to have a high risk of concomitant esophageal cancer, endoscopic screening with iodine staining was performed on 788 patients with head and neck cancers. Among them, 93 cases of esophageal cancers (11.8%) and 23 cases of gastric cancers (2.9%) were detected. Seventy-two cases (77.4%) of the 93 esophageal cancers were superficial cancers limited to the submucosal layer. Twenty cases, treated by EEMR, had a good postoperative course without local recurrence. We suggest that endoscopic screening for esophageal cancer should be performed on all patients with head and neck cancers, because it allows early detection and a good prognosis, and the treatment can be completed by endoscopic maneuver.

Abstract
We report herein the case of a 36-year-old woman in whom a breast mass was diagnosed histologically and immunohistochemically as myofibroblastoma (MFB). The patient initially presented with a breast mass measuring 1.0 x 1.5 cm which was demonstrated by mammography as a well-circumscribed, round tumor with two coarse calcifications. On ultrasonography, the tumor showed slight shadowy internal echoes. Histological examination of an excisional biopsy specimen demonstrated a tumor consisting of spindle-shaped cells and broad bands of hyalinized collagen with cartilaginous and osseous components, but no epithelial components were observed. Immunohistochemically, the tumor cells were diffusely positive for alpha smooth muscle actin, and a diagnosis of MFB was made. A wide excision of the breast was performed as a secondary procedure, and the patient is well and free from recurrence 1 year after her operation. We present this case to stress the need for breast surgeons to be aware of the existence of MFB when considering the differential diagnosis of stromal lesions of the breast to avoid performing unnecessarily extensive procedures.

Abstract
Somatotroph adenomas often secrete prolactin (PRL) besides growth hormone (GH) and are sometimes immunostained for other anterior pituitary hormones or their subunits, such as thyroid-stimulating hormone (TSH) beta-subunit and glycoprotein hormone alpha-subunit (alpha SU). However, somatotroph adenomas showing hypersecretion of adrenocorticotropic hormone (ACTH) are extremely rare. There have been, to our knowledge, only five published reports on somatotroph adenomas accompanied by excessive ACTH secretion. Here we report a case of intracavernously invading somatotroph macro-adenoma with high serum GH, PRL, and ACTH levels. We examined the case using immunohistochemistry (IHC), in situ hybridization (ISH), and cell culture, and confirmed GH, PRL, and ACTH, as well as alpha SU, production, and the expression of Pit-1 protein by the adenoma, which is known as a transcriptional factor for GH, PRL, and TSH, not for ACTH. Therefore, the presence of unknown transcriptional factor other than Pit-1, common to GH, PRL, and ACTH, may be speculated to be expressed in this adenoma. In our previous study, we had found plurihormonal mRNA expression, especially for ACTH, the beta-subunit of follicle-stimulating hormone and luteinizing hormone in some somatotroph adenomas, using non-radio-isotopic ISH, and suggested that these adenomas might be derived from plurihormonal primordial stem cells. Our present case is significant from the viewpoint of histogenesis of pituitary adenomas, because it further supports the cell origin of somatotroph adenomas from plurihormonal primordial stem cells, and moreover it suggests the presence of unknown transcriptional factor other than Pit-1, common to GH, PRL, and ACTH.
