Abstract
BACKGROUND Magnifying endoscopy has demonstrated dramatic morphologic changes in the surface microvasculature of superficial esophageal squamous cell carcinoma (ESCC) according to the depth of invasion. We investigated the mechanism of angiogenesis in early-stage ESCC by examining the expression of vascular endothelial growth factor (VEGF)-A and chondromodulin (ChM)-1. METHODS Using 41 samples of superficial esophageal cancer (EP and LPM 19 cases, MM or deeper 22 cases) and 7 samples of regenerative squamous epithelium, the expression of VEGF-A and ChM-1 was examined in relation to the histological grade or morphology of the surface microvasculature demonstrated by magnifying endoscopy (types A, B, and C correspond to types A, B1, and B2 and B3 of the magnifying endoscopic classification of the Japan Esophageal Society, respectively). We also investigated the correlation between CD31-positive microvessel density (MVD) and VEGF-A or ChM-1 expression. RESULTS In normal squamous epithelium, regenerative squamous epithelium, EP and LPM cancer, and MM or deeper cancer, the positivity rates for VEGF-A and ChM-1 were 0%, 85.7%, 52.6% and 90.9%, respectively, and 48.5%, 71.4%, 73.7% and 23.8%, respectively. The VEGF-A and ChM-1 positivity rates in type B or type C vasculature were 70.0% and 76.2%, respectively, and 75.0% and 19.0%, respectively. The expression of neither VEGF-A nor ChM-1 in cancer cells was correlated with MVD (P = 0.19 and 0.68, respectively), whereas that of VEGF-A in stromal mononuclear cells (SMCs) was significantly correlated with MVD (P = 0.04). CONCLUSION Angiogenesis at the early stage of ESCC progression is configured by the balance between accelerator (angiogenic factors from both cancer cells and SMCs) and brake (angiogenic inhibitor) factors.

Abstract
OBJECTIVE The esophagus is the only organ where changes in the superficial microvasculature from normal squamous epithelium to invasive cancer are evident by magnifying endoscopy. We investigated in detail the features of angiogenesis in early-stage esophageal cancer using CD34 and CD105 immunostaining, and also the correlation between angiogenesis and mononuclear cell infiltration. MATERIALS AND METHODS Using 10 samples of normal squamous epithelium, 7 samples of low-grade intraepithelial neoplasia, and 45 samples of superficial esophageal cancer, we determined the microvessel density at hot spots showing positive staining for CD34 and CD105. We observed the histological features of CD34- and CD105-positive microvessels that corresponded to observations made by magnifying endoscopy. We then investigated the correlation between microvessel density and each histological situation or the grade of mononuclear cell infiltration. RESULTS The histological features of CD34- and CD105-positive microvessels were able to explain the morphological changes in the microvasculature during cancer progression observed by magnifying endoscopy. The microvessel density for CD34 or CD105 was significantly correlated with each of the histological types (P < 0.001, rS = 0.51 and 0.76, respectively). Mononuclear cell infiltration at CD105 hot spots was most frequent in M1 and M2 cancer (94.7%). The correlation between the degree of mononuclear cell infiltration and microvessel density for CD105 staining was also significant (P < 0.001, rS = 0.49). CONCLUSIONS The microvessel density based on CD34 and CD105 immunostaining can be used to corroborate observations of superficial esophageal squamous cell carcinoma made by magnifying endoscopy. Mononuclear cell infiltration may play an important role in angiogenesis at the early stage of cancer progression.

Abstract
Observations of esophageal squamous cell carcinoma using magnifying endoscopy have now been carried out extensively and, as a result, it has become clear that the morphology of the microvessels evident at the tumor surface reflects the depth of tumor invasion. In M1 and M2 cancer, the surface microvasculature reveals dilation and elongation of the intrapapillary capillary loops (IPCL). However, at this stage, some immature capillaries resembling IPCL also arise inside the tumor and, therefore, the view of the microvasculature should be described as one showing 'intermixing of modified IPCL and IPCL-like immature capillaries (IPCL-like abnormal capillary)'. As cancer invades into the muscularis mucosa (M3 or deeper), an obviously dilated and irregularly branched tumor-specific vasculature, more accurately described as 'neovasculature', can be observed. From our magnifying endoscopy observations and studies of the molecular profile of early esophageal cancer, we conclude that two major angiogenic steps exist in precancerous and M3 lesions in the early phase of cancer progression. In addition, it is now possible to study cell morphology using an endocytoscope with a much higher magnification (×400-×1000) than magnifying endoscopes currently on the market. The histology revealed in this way may reduce the need for conventional biopsy histology in the future.

Abstract
Gastric cancer is the seventh and oesophageal cancer the ninth most common cancer in the UK, and >50% of patients present with locally advanced or metastatic disease. The incidence of oesophageal and oesophagogastric junctional tumours is increasing, making these important disease entities to understand and research. Despite improvements in surgical and peri-operative supportive care, 3-year overall survival with surgery alone for resectable disease is still poor. Outcomes in localised oesophageal cancer are improved with pre-operative chemotherapy, and in gastric cancer with peri-operative treatment or post-operative chemoradiotherapy. Oesophageal squamous cell carcinoma can be treated with definitive chemoradiotherapy as an alternative to surgery. While survival in patients presenting with metastatic disease is improved with the addition of systemic chemotherapy, median survival remains <1 year. Patients who are otherwise fit can be offered chemotherapy and this is superior to best supportive care. Regimens including a platinum and an anthracycline agent are favoured by the results of randomised trials. No standard second-line therapy has emerged. New research into taxanes has shown promising anti-cancer activity, and novel areas of investigation include incorporation of agents targeting vascular endothelial growth factor or epidermal growth factor receptor into standard regimens. This review focuses on the clinical trial evidence that dictates the optimal management of localised and advanced oesophagogastric cancer, focusing on pharmacotherapy. We examine areas of current research and highlight future therapeutic directions.

Abstract
The most common genetic alterations found in a wide variety of cancers are p53 tumor suppressor gene mutations. p53 appears to be a nuclear transcription factor that plays a role in the control of cell proliferation, apoptosis, and the maintenance of genetic stability. Angiogenesis is a critical process in solid tumor growth and metastasis. Vascular endothelial growth factor (VEGF), a recently identified growth factor with significant angiogenic properties, may be a major tumor angiogenesis regulator. Few studies have investigated the association between p53 and VEGF expressions and prognosis in esophageal carcinoma. Forty-seven specimens resected from patients with stage II and III squamous cell carcinoma (SCC) of the esophagus were studied using immunohistochemical staining. VEGF and p53 expressions were observed in 40% and 53% of the tumors, respectively. The p53 and VEGF staining statuses were coincident in only 21% of the tumors, and no significant correlation was found between p53 and VEGF statuses. No clinicopathologic factors were significantly correlated with p53 or VEGF expression. No significant association between p53 and VEGF expressions and poor prognosis was found. In conclusion, p53 and VEGF were not correlated with prognosis in patients with stage II and III SCC of the esophagus.

Abstract
The vascular structure of cancer changes during tumour progression. A particularly dramatic change occurs during the early phase of progression when in situ tumour is transformed to invasive cancer. Recent advances in morphological investigations have made it possible to visualise and characterise the microvascular-network alterations. In addition, laboratory studies have also revealed the molecular profile--the changing levels of expression of different proteins--of cancer progression, which has helped to advance understanding of the mechanism of carcinogenesis. In this review, we discuss recent outcomes of research of oesophageal cancer and consider the responses of the vascular network and the development of new blood vessels during the early phase of cancer progression. Such considerations will be useful not only for understanding vascular biology but also for exploring novel diagnostic, therapeutic, and preventive approaches targeting early stage or latent phase human cancer.

Abstract
Epithelial-stromal interactions are important not only in growth, development, and functional cytodifferentiation of the prostate but also in derangements of prostate gland such as BPH and prostate carcinoma. This chapter explores the roles of epithelium and stroma during this delicate process and highlights the role and mutual influence of each on the other. It also examines the importance of ECM in mediating the effects of androgens and drawn attention to estrogen and genetic factors in the process. During this process of epithelial-stromal interaction, growth factors play a central role in mediating the interactions. This chapter focuses on the role of several growth factors including epidermal growth factor, fibroblast growth factor, transforming growth factor alpha, transforming growth factor beta, insulin-like growth factor-1, vascular endothelial growth factor, nerve growth factor, platelet-derived growth factor, and hepatocyte growth factor. This chapter emphasizes the importance of epithelial-stromal interactions in tumorigenesis and highlights the switch of paracrine to autocrine mode during the process of carcinogenesis.

Abstract
We report the close correlation between changes in serum immunoreactive vascular endothelial growth factor 165 (iVEGF165) levels and metastatic tumor burden measured by computed tomography scan before treatment, during the antitumor response, and during early progression in a patient treated with ex vivo gene therapy for renal cell carcinoma. With the researcher blinded to outcome, iVEGF levels were measured in archived serum samples from a patient with metastatic renal cell carcinoma who demonstrated a 7-month partial remission to treatment with autologous, irradiated human GM-CSF gene transduced tumor vaccine. Although a spontaneous regression could not be formally excluded in this patient, the appearance of 20 new pulmonary metastases on computed tomography scan after nephrectomy and before vaccination indicates that if spontaneous regression occurred, it took place at the start of vaccine treatment.
