Our hospital fights against a clinical study clearly. However, our hospital did not participate in a clinical study here. When I widened a clinical study in cooperation with the staff, I make a progress report. I started a clinical study only with a doctor first. Therefore it was recognized many problems happened and to promote a clinical study without cooperation of the work of many kinds. I studied with the staff to promote a clinical study and deepened understanding. Thereafter the clinical study was led by a nurse of the chemotherapy room; , in addition, was able to get various cooperation from a skiagrapher. When OGSG0603 began, the nurse and the pharmacist served to become the key than a doctor. I was able to promote a clinical study by cooperation of much staff. In addition, I was able to carry out the system improvement of each section by performing a clinical study.
