It is the role of the "prostate treatment center" to take care of everything from diagnosis to treatment of a prostate disease
centered on "minimally invasive medical care" that places less burden on the body.
The three pillars are laparoscopic operation using the surgical support robot "Da Vinci Xi" that enables safe and reliable surgery, the robot-type radiation device "Cyberknife" that can pinpoint the nidus, and radiation therapy used and "small sealed treatment" in which a small radiation source is embedded in the body to perform radiation therapy. By introducing these advanced medical treatments, treatment options will be greatly expanded to patients with complications and anxiety about surgery and elderly patients, and it will be tailored to each patient, and it is possible to provide tailor-made treatment tailored to each patient.
- Minimally invasive medical care
- "Invasion" is a medical term that broadly means "damaging the body" in medical practice. In particular, the procedure involves a large amount of "invasion" for the patient, such as the incision causing a large injury to the body and the loss of a part of the organ. However, with the progress of medical technology, minimally invacive treatment has become possible in recent years not only to cure illness but also to reduce the burden on the body as much as possible. Laparoscopic surgery and robot surgery, which can reduce the scars caused by the incision, greatly contribute to the reduction of pain and bleeding, and the early recovery after surgery. In addition, advances in technology that can irradiate radiation only to cancer have made it possible to obtain merits such as suppressing damage to surrounding organs and reducing side effects while obtaining a high therapeutic effect.
Patients have different medical conditions and needs, such as "I was told that it was difficult to perform surgery because I have a chronic disease," "I don't want to stay in hospital," "I am worry about side effects," and "It is hard to go to the hospital." At our center, we are introducing advanced medical treatment such as the surgical support robot "Da Vinci Xi", the robot-type radiotherapy device "Cyberknife", and "small sealed treatment", so that it is possible to choose a custom-made treatment method individualized for each person.
Approximately 300 Da Vinci and 40 Cyberknife are in operation in Japan. There are about 110 facilities that offer small sealed treatment, but few have all three advanced medical treatments.
"Da Vinci" has been used by more than 440 patients since its introduction in 2012, and "small sealed treatment" has been used by more than 500 patients with prostate cancer since its introduction in 2007, with good treatment results. In addition, stereotactic radiotherapy for prostate cancer has been covered by insurance since 2016, and the number of days required for radiation therapy using Cyberknife has been significantly reduced (37-39 times → 5 times). For patients undergoing stereotactic radiotherapy and small sealed treatment, we have also introduced the space OAR system as a preventive measure for rectal sequelae (melena, anal pain, etc.) that occur shortly after treatment.
We treat patients with confidence and pride so that we can provide the best medical care to them, so please feel free to contact us.
- Overview
- The surgical support robot "Da Vinci Xi" is used for "laparoscopic surgery" in which a bore is opened in the abdomen, a camera is inserted, and the nidus is removed while observing the image. The robot part of Da Vinci is equipped with three arms that can be equipped with electric scalpels and a camera, and the doctor operates the arms while observing the high-quality and stereo 3D image projected on the operation portion, and the cancer is resected and the affected area is sutured. Safe and reliable operations are possible with the movement of the robot, which is more precise than that of humans.
- merit
- cystoprostatectomy by Da Vinci was covered by health insurance in 2012. Since then, it has spread rapidly, and more than half of cystoprostatectomy in Japan is now performed by Da Vinci, and the surgical results are also good. The benefits have been reported that "Low amount of bleed" "Low postoperative pain" "Fast recovery and early discharge possible" "Less cancer left behind" "Low postoperative urinary incontinence" "High erectile function maintenance rate" etc. . Since the introduction of Da Vinci in 2012, more than 400 prostate cancer patients have undergone Da Vinci surgery at the Tobu Hospital. In addition, Da Vinci is also used in surgery other than cystoprostatectomy, and we have a wealth of experience in using Da Vinci.
* Intraocular pressure may increase during surgery, so check for eye diseases. This is a procedure to store your own blood just in case there is a lot of bleeding.
- Overview
- Since April 2016, we have been conducting stereotactic radiation therapy (SBRT) covered by health insurance. "Cyberknife" is a high-precision radiotherapy device that combines an X-ray irradiation device with a robot arm. The robot arm, which can irradiate from 1200 directions at the maximum, can handle complicated anterior gland shapes with an accuracy of millimeters or more. It is known that the position of the prostate gland is moved by intestinal gas and urine collected in the bladder. By placing a gold marker (hospitalization for 2 nights and 3 days) in the prostate prior to treatment, it is possible to irradiate while grasping the exact position of the prostate.
- merit
- The conventional intensity-modulated radiotherapy part (IMRT) requires 37 to 39 irradiations, and it is a heavy burden that outpatient treatment lasts for 7 to 8 weeks. SBRT with a pinpoint-capable Cyberknife can concentrate a sufficient amount of radiation on the prostate and minimize the effect on the surroundings. For prostate cancer, 5 outpatient irradiations every 1 to 2 days, treatment is completed in 2 weeks. It is also characterized by no pain during irradiation and less strain on the body.
- "Space OAR system"
- A method of injecting hydrogel between the prostate and rectum for the purpose of preventing rectal sequelae (melena, anal pain) caused by radiation, which has been implemented at Tobu Hospital since March, 2018. Hydrogels harden when are injected into the body and are absorbed after a few months. The hydrogel creates a space between the prostate and the rectum, which significantly reduces the radiation on the rectum. The injection is done at the same time as the gold marker is placed, so there is no special burden.
- Overview
- This is a treatment method in which a small radiation source that emits weak radiation is inserted into the body (inside the anterior gland) and the radiation is emitted from inside the body. When implanting the radioactivity, use a computer to select a position that has a high therapeutic effect and has little effect on other organs. A great therapeutic effect can be expected by being able to irradiate the radiation concentrated in the anterior gland.
- merit
- Since the radiation emitted from the inserted radioactivity is concentrated in the anterior gland, there are few complications such as urinary incontinence and erectile disorders, and the procedure can be performed in a short hospital of 3 nights and 4 days. Dysuria occurs as a side effect, but most of them improve in about 6 months to 1 year. Depending on the medical condition, brachytherapy may be combined with outpatient radiation or endocrine treatment. Please consult your doctor for details.

* Brachytherapy and extracorporeal irradiation may be used in combination for more effective treatment (improvement of curability).
