Introduction

A. Facility specializing in pediatric endoscopic surgery

Although the number of patients requiring pediatric surgery is small, their diseases markedly vary. Therefore, in order to appropriately treat such patients, it is important to intensively perform a large number of surgeries for them in a single facility. We perform more than 700 surgeries annually in- and outside the hospital, and are expected to play a central role in developing new treatment methods and educating/training pediatric surgeons as a high-volume center. We treat patients from the Tokai and other distant districts through collaboration with related departments (such as the Departments of Pediatrics, Obstetrics and Gynecology, Cardiovascular Surgery, Urology, Orthopedics, Ophthalmology, Otolaryngology, Plastic and Reconstructive Surgery, Anesthesiology, Intensive Care, and Internal Medicine). With Doctor Uchida, who has the most extensive experience of pediatric endoscopic surgery in Japan, assigned in August 2013 we treat patients with congenital esophageal atresia, congenital lung diseases, biliary atresia, congenital biliary dilatation, and other disorders requiring high-level endoscopic surgery, while considering appropriate methods to reduce the burden on these children daily.

B. Extensive experience of dealing with hepato-biliary-pancreatic diseases

Up to the present, we have actively dealt with hepato-biliary-pancreatic diseases, such as biliary atresia, congenital biliary dilatation, and liver transplantation. We perform treatment, while not only improving surgical treatment methods, but also examining countermeasures against complications and the challenges of long-term follow-up. As part of such treatment, we are also engaged in living donor liver transplantation to be performed within the hospital through collaboration with the Department of Transplantation Surgery.

C. Comprising the General Perinatal Medical Center to treat newborns requiring surgery

Our facility was designated as a General Perinatal Medical Center in Aichi Prefecture in April 2012. Such centers are medical institutions designated by municipalities to provide advanced medical services for pregnant females and newborns with severe conditions. The center consists of 2 major divisions: reproductive medicine/perinatal; and neonatal. The latter comprises the NICU and GCU with 12 and 24 beds, respectively, in addition to the Departments of Obstetrics, Pediatrics, and Pediatric Surgery which closely collaborate and regularly hold joint conferences. It provides surgical treatment for extremely-low-birth-weight infants and pediatric patients with congenital diseases requiring advanced management through collaboration with related departments and external medical institutions in the vicinity.

D. Designated as a pediatric cancer hub hospital

As a large number of hospitals deal with pediatric cancer despite the small number of patients with it, it is difficult for some hospitals to obtain extensive treatment experience in this area. As a solution, the Ministry of Health, Labour, and Welfare designated a pediatric cancer hub hospital to centralize patients with pediatric cancer refractory to treatment and those requiring highly specialized treatment, and provide them with high-quality medical services in each district. Such hospitals are selected based on the results of evaluation by experts from comprehensive perspectives, covering medical service systems/equipment, training systems, and clinical research activities, as well as treatment outcomes. Having been evaluated the most favorably nationwide, our department was selected as a hub hospital for the Tokai/Hokuriku/Shinetsu Block in February 2013, together with Mie University Hospital. In line with this, Nagoya University Hospital aims to establish more appropriate medical service systems by further improving the quality of staff and equipment for pediatric cancer treatment and cooperating with other medical institutions within the block.

Project title 2：
Development of a next generation photothermal therapy using a light-absorbing drug that selectively accumulates in lesions for pediatric cancer

ICG lactosome, a novel drug delivery system (DDS) type photothermal agent that is composed of polymeric micelle and indocyanine green (ICG), show a selective accumulation in cancer based on EPR effect. We showed the selective accumulation in tumors through animal experiments using the ICG lactosome and showed the utility in tumor imaging with the fluorescence derived from ICG as an indicator. On the other hand, ICG is known to be an infrared absorbing substance, thereby when a tumor in which ICG accumulate is irradiated with infrared light, only the tumor can be heated by photothermal reaction. We have found that when irradiation is performed so that the tumor temperature is 43 ° C or higher by adjusting the light output, the tumor can be eliminated with a probability of almost 100%.
Therefore, in this study, we aim to develop an endoscope based high efficiency cancer therapy system using ICG lactosome and a thermal control mechanism in order to treat the tumor lesions that can be reached with an endoscopic approach. When this therapeutic system becomes to be clinically applied, more selective diagnosis for tumor locations can be achieved for infiltrative tumors and metastatic tumors of childhood cancers than fluorescence imaging method using conventional ICG (without DDS). Moreover, curative treatment for the tumors by the photothermal reaction can be carried out simultaneously. This diagnostic and therapeutic system is minimally invasive and it is an innovative methodology that can be repeatedly applied until tumors disappear every time invasive lesions or metastatic lesions are found.
In the first half of the research period, ICG lactosome is administered to tumor model animals transplanted with childhood cancer cell lines (neuroblastoma / hepatoblastoma) transfected with a luminescent gene that express a high luminance, followed by photothermal treatment, suitable conditions (irradiation intensity and time, concentration of ICG lactosome, etc.) for maximizing the antitumor effects are to be elucidated especially for pediatric invasive or metastatic tumor. On the other hand, in order to realize the endoscope-based high-efficiency cancer treatment system with the photothermal control mechanism, we intend to fabricate three elemental technologies as follows; (i) an irradiation system that can efficiently deliver light to lesion sites, (ii) a thermography endoscope, (iii) a control system for tumor temperature. In the latter half of the period, animal models of orthotopic tumors are subjected to an endoscopic surgery with the developed integrated system in order to sublimate it into a technology that contributes to clinical use.

Project title 3：
Determination of new biomarkers for pediatric cancer based on comprehensive analysis of urine metabolites

Pediatric cancer is a number-one cause of child mortality, but pediatric cancer control measures are still inadequate. In many cases, tumors have already metastasized to other organs and moved to other parts of the body when they are discovered, making treatment very difficult. A minimally invasive technique for early discovery of pediatric cancer could be expected to improve treatment success. In fact, for most cases the earlier pediatric cancer is treated, the better chance of success—early detection is directly related to prognosis. When it is difficult to remove tumors surgically or there is a chance that tumor mass remains even after surgery, chemo- or radiation therapy is often used, but when effective markers for tumors cannot be found, medical imaging can be the only effective diagnostic method. This applies to tumors such as Wilms’ tumors, striated muscle sarcoma, osteosarcoma, and the Ewing family of tumors. CT and PET imaging is effective in diagnosing remaining tumor, but when even these methods are not conclusive, very invasive treatments are needed to biopsy or remove remaining tumor mass. Even when techniques such as PET are conclusive in finding remaining tumor, it is used repeatedly over long periods in most pediatric cancer cases, raising considerable concern that the treatments themselves could be carcinogenic. For such tumors, discovery of non-invasive tumor markers would bring immeasurable benefit in diagnosis and treatment for children in the future. Metabolites in urine are stable and less affected by enzymes than substances in blood, so they hold promise as tumor markers. Urine tests are also easy to administer to children, so they can be used easily for screening. As such, we began a search of for new tumor markers in urine through a comprehensive analysis of urine metabolites. We are looking for tumor markers that are more sensitive and reflect more on the prognosis, even for
diseases for which markers are known already. The aims of our research are (1) early discovery of pediatric cancer through simple, non-invasive urine testing, and (2) to search for new markers in urine that will contribute to early detection of treatment effectiveness and recurrences for pediatric cancers that cannot be detected through blood sample tumor markers. Practically speaking, we will seek metabolites with potential as tumor markers by collecting urine samples from children, and performing a comprehensive analysis of urine metabolites using liquid chromatograph mass spectrometer.
