In the clinic, we care for patients with breast, urologic, and gynecologic cancers, as well as sarcoma. We also provide the best available treatment to patients with cancers of unknown primary, multiple primary cancers, or other rare cancers that are difficult to treat in other hospitals.

In 2021, we saw the greatest number of new patients in our department’s history. We newly formed a multidisciplinary conference for bone and soft tissue sarcoma in collaboration with the Department of Musculoskeletal Oncology. We also played a central role in implementing multi-gene panel testing, which came under insurance coverage in 2019. Our department’s chief, Dr. Mukohara, serves as Head of the expert panel (molecular tumor board). We managed 173 out of 383 total cases that were discussed in our expert panel, which contributed to genomic medicine in several regions. We also contributed to the operation of the “Lady’s Center” which opened in 2018 as a core of multi-disciplinary care for women with cancer.

This year, we launched a new investigator-initiated trial (IIT) of limb-cooling as a means to mitigate paclitaxel-induced sensory neuropathy (CECILIA trial) (PI: Toru Mukohara). For another IIT of olaparib +/- pembrolizumab as neoadjuvant therapy for advanced ovarian cancer (PI: Kenichi Harano), which we launched last year, patient recruitment went as planned, and adjunct translational research utilizing single-cell RNA sequence technology is underway in collaboration with the Division of Genome TR. We are also conducting collaborative studies with a technology company to explore the clinical utility of their system for detecting circulating tumor cells (CTCs)

Research activities

We are participating in many company-sponsored trials and other collaborative studies of clinical trial groups, such as JCOG, JBCRG, and WJOG.

We are also implementing clinical and translational research projects with funds obtained from the Grants-in-Aid for Scientific Research (“3D coculture of cancer cells in malignant effusion/CTC with adipose stem cell”; PI: Mukohara T) (“New sub-classification of triple-negative breast cancer to evaluate immunogenicity”; PI: Kogawa T).

In addition, our residents published four English papers under the guidance of the staff members of our department.


Our goal in education is to foster “genuine” medical oncologists. Graduates from our resident / chief resident programs are expected to provide not only standard therapies regardless of cancer type but also multi-disciplinary care in cooperation with other medical professionals. Obtaining skills for palliative care and dealing with oncological emergencies are also expected.

Further, we require and help them to implement clinical research to address clinical questions they develop themselves and report the results in international journals. This is because we aim to develop scientific clinicians who can focus on issues scientifically and create evidence for themselves. As an achievement, this year, two of our residents earned the title Diplomate, Subspecialty Board of Medical Oncology, JSMO.

Further, we earned an educational grant with the theme “Comprehensive educational program to develop medical professionals and peer supporters to empower Adolescent and Young Adult (AYA) breast cancer patients”. We held a multidisciplinary AYA conference (mAYAcon) to deliver optimal care to AYA cancer patients and to conduct educational programs for medical professionals.

Future prospects

In the clinic, we will provide clinical care with high patient satisfaction through a multidisciplinary team approach. In education, we will foster medical oncologists with skills and knowledge for cross-organ oncology care and scientific acumen. In research, we will initiate multi-center clinical trials and Phase I to III developmental trials of investigational drugs. We will also investigate resistance to anti-cancer drugs. Multiple research themes are currently under discussion with industries and other academic organizations.
