Treatment Methods (Cancer Treatments That Improve QOL)

Mastectomy (removal of the breast) has been the standard surgical procedure for breast cancer, however, an increasing number of medical facilities are now providing surgical procedures to preserve the breast. Here at our center. in addition to carrying out breast-conserving surgery as often as possible, we are assertively performing minimally invasive endoscopic surgery, which leaves only small scars and causes little pain. Although this procedure requires an advanced set of skills, it allows us not only to cure cancer, but also to conserve the breast without significant cosmetic alterations, which leads to a greater quality of life (QOL). Also, we have undertaken state-of-the-art breast reconstruction using the patient’s own fat stem cells, and we are proud of our world-leading skills.

We carry out minimally invasive surgery for gastroenterological cancer as well, and perform numerous surgeries such as endoscopic mucosal resection (EMR), which enables en bloc resection of the cancer under an endoscope, and endoscopic submucosal dissection (ESD), which allows on bloc resection of cancer using a diathermic knife installed at the tip of the endoscope.

For blood cancer, one of the few chemotherapy specialists in Japan and Asia who is also a medical oncologist works at our institution. He is a leading figure in chemotherapy and continues to assertively incorporate cutting-edge methods of chemotherapy that are significantly advancing international treatment standards. Moreover, we annually perform 20-30 bone marrow transplant, peripheral blood transplants and cord blood transplants. Our expertise in these transplants is ranked among the top in Japan. In stem cell transplantation, we carefully maintain room sterility, and the level of our performance results ranks highly on an international level.

Features of Our Center

JCI Accreditation  Trademark

Kameda Medical Center collectively represents our healthcare service facilities, including Kameda General Hospital, Kameda Clinic, Kameda Rehabilitation Hospital, and others. In 2009, the center became the first medical institution in Japan to be accredited by the Joint Commission International (JCI), a healthcare facility accreditation service located in the United States. We have been accepting international patients through our International Office, which provides a number of services, from coordinating plans for the patient’s appointment and communicating with his/her health insurance company, to arranging his/her aftercare and answering inquiries regarding visitation and training programs. We receive numerous inquiries from abroad and admit 1200 international patients annually to our facilities and its attractive amenities.

The main feature of cancer treatment at our hospital is that specialists in three major standard therapies for cancer, surgery, radiotherapy, and chemotherapy, come together and serve as a collaborative team to provide an appropriate and timely therapy for each patient. Oncologists specializing in different cancers (some of the few specialists in Asia at this point in time) form a highly competent team, carrying out an essential role in our medical team. In addition, capitalizing on our strength as a general hospital, our specialists in each department perform examinations for a comprehensive check-up, and we are able to provide safe and effective treatments for patients who have complications related to heart disease, cerebrovascular disease, respiratory disease, and others, as well as aging adults with cancer who are more likely to have such multiple complications.

Furthermore, we have established a urogynecology center a rarity in Asia, which specializes in urogynecological surgery (pelvic organ prolapse, urinary incontinence), where clinical specialists in gynecology, urology, and recto-anal surgery work closely together to provide appropriate diagnoses and therapies.
