The Effect of Electro-Hyperthermia in Preoperative Radiotherapy for Locally Advanced Rectal Cancer
A study testing Electro-hyperthermia in people with Rectal Cancer and Hyperthermia, run by Yonsei Hyperthermia Study Group at 1 site in South Korea.
Trial summary
Preoperative radiotherapy in locally advanced rectal cancer increases the possibility of complete resection and anal sphincter preservation. However, a treatment period of from 5 to 6 weeks is an obstacle of proper surgical intervention. Read more about this study

About this study
Official title: The Effect of Electro-hyperthermia in Preoperative Radiotherapy Followed by Delayed Operation for Locally Advanced Rectal Cancer: Phase II Single Institutional Study
Preoperative radiotherapy in locally advanced rectal cancer increases the possibility of complete resection and anal sphincter preservation. However, a treatment period of from 5 to 6 weeks is an obstacle of proper surgical intervention. Also, radiotherapy itself is confronting challenges for maximizing the therapeutic effect and minimizing the side effects. Electro-hyperthermia is appropriate treatment method to solve these kinds of problems. In this clinical trial, therapeutic effect of the high-frequency electro-hyperthermia is to be verified during preoperative radiotherapy for locally advanced rectal cancer. The ultimate goal is to establish a safe and effective treatment protocol.

The endpoint of the trial is treatment safety and non-inferiority of tumor regression to conventional schedule of preoperative radiotherapy.

Where is the study taking place?
The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
T stage (0 - 4), N (0 - 3) stage, tumor regression grade (0 - 4) (time frame: 3 months after curative surgery by surgical pathology report). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02546596, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2021; AzTrials last refreshed its copy on 8 Nov 2026.
