Introduction

The Department of Gastrointestinal Medical Oncology focuses on treatment in clinical practice, development of new drugs, and establishment of standard chemotherapy regimens including multi-modality treatment with surgery and/or radiotherapy for gastric/colorectal/gastrointestinal stromal tumor (GIST), and other gastrointestinal (GI) malignancies.

The Team and What We Do

The staff of our division consists of 7.5 medical oncologists and three or four rotating residents. We have a daily case conference every evening for discussing each patient’s treatment and a weekly research conference for sharing and discussing the progress of clinical studies and/or translational research. Multi-disciplinary team meetings with the surgical divisions (Colorectal and Gastric Surgery Divisions) and the Radiation Oncology Division are held weekly to decide optimal treatment strategies for each patient and to discuss the treatment consensus for each disease. From April 2021 to March 2022, we treated 527 hospitalized patients (excluding head and neck and esophageal departments, and including 216 new patients), including 223 with gastric cancer, 237 with colorectal cancer, 17 with anal canal cancer, 10 with GIST, and 9 with small bowel cancer.

Research activities

Clinical research to establish new treatments and answer clinical questions. As for the late phase clinical studies, our division is playing a leading role in JCOG (Japan Clinical Oncology Group) and WJOG (West Japan Oncology Group), which are the largest cooperative study groups for cancer treatment in Japan. As an early phase clinical study, in collaboration with other active hospitals, we are conducting investigator-initiated trials using unapproved drugs under the regulation of the GCP (Good Clinical Practice). Moreover, we collaborate with the National Cancer Center Research Institute and other distinguished basic research institutions to conduct clinical research based on our own original new ideas and findings. From March 2021 to March 2022, 147 patients were enrolled in clinical trials/trials (Table 1). We presented in 46 conferences, 19 of which were international. We published 58 papers, 45 of which were original article in English, 8 review article in English, and 5 in Japanese. Of these, our department was the First or Corresponding Author for 20, and most of them were international multicenter trials, investigator-initiated trials, JCOG trials, and their accompanying results.

Clinical trials

We are conducting many clinical trials, including JCOG, WJOG, company-initiated, and other collaborative investigator-initiated trials and in-house clinical trials. A total of 147 patients were enrolled in 2021 (Table 1).

Education

In clinical practice, full-time doctors and oncology trainees/residents form teams and conduct guidance through the patients in their charge. In addition, we assign research themes to oncology trainees/residents, and energetically provide guidance on clinical research planning, management, conference presentations, and thesis writing. From April 2021 to March 2022, 10 English papers and 5 Japanese papers were written by cancer specialists/residents of our department as the first author.

Future prospects

Our division focus on “clinical practice”, “education” and “clinical research” for the development of gastrointestinal cancer treatment. For daily practice, we give the patients the standard treatment; moreover, we will always pay attention to improving patient care to satisfy unmet clinical needs. For education, we will keep educating the residents and chief residents; moreover the staff doctors will strive to keep improving themselves. For clinical research, we will strive toward the next step of clinical development to establish new global standard treatments.
