Yonsei Cancer Hospital announced on the 4th that it had performed 1,000 cases of brachytherapy on prostate cancer patients.
Brachytherapy is a procedure that involves permanently inserting radioisotopes into the prostate of a prostate cancer patient using a needle. The 60-100 radioisotopes inserted into the body generate radiation for approximately 3-4 months immediately after the procedure and kill cancer cells. technology. It can be applied to patients with localized prostate cancer without metastasis.
Brachytherapy, used as one of the three main treatments for prostate cancer along with external beam radiation therapy and surgery, has developed steadily since the 1970s. The first-generation procedure required an actual incision in the patient’s skin and manual implantation of radioisotopes, while the second-generation procedure used rectal ultrasound to insert the radioisotope into the perineum, but the treatment effect was low due of the low energy emitted by the radioisotope. the isotope. From the 3rd generation it was possible to vary the proportion of isotopes placed in cancerous and non-cancerous areas, reducing the side effects of the procedure, but the radiation dose distribution could only be confirmed after completion of the procedure.
As a result, the latest fourth-generation brachytherapy treatment performed by Yonsei Cancer Hospital is a method that allows the insertion of radioisotopes at a more precise location and in the correct direction by controlling the radiation dose in real time during the procedure. the shortcomings of existing brachytherapy treatment and stated that this is a step forward.
In particular, treatment with brachytherapy has the advantage of having fewer side effects such as urinary incontinence and erectile dysfunction, of allowing the return to daily life immediately two days after the operation and is also effective in the treatment of tumors since high doses can be irradiated on tumors. minimizing the impact on surrounding normal organs.It is known.
Professor Jae-ho Cho from the Department of Radiation Oncology said: “Not only are the treatment results of prostate cancer patients who received brachytherapy treatment very excellent, but they are also able to return to their daily lives in about two days after the procedure,” And he adds: “Even in the case of patients with chronic diseases such as obesity or who are elderly, “it is possible to receive brachytherapy treatment,” he said.
