Deep Hyperthermia Combined With Neoadjuvant Concurrent Radiochemotherapy for Locally Advanced Rectal Cancer, PUTHRC-001：A Multi-Center, Open-Label, Randomized Controlled Study

The purpose of this study is to determine whether adding deep hyperthermia to neoadjuvant concurrent radiochemotherapy could improve T-downstaging rate for locally advanced rectal cancer (LARC).

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The purpose of this study is to determine whether adding deep hyperthermia to neoadjuvant concurrent radiochemotherapy could improve T-downstaging rate for locally advanced rectal cancer (LARC). The sample size is 142. Patients with LARC (T3-4/N+) will be randomly divided into intervention group and control group. For intervention group, the neoadjuvant therapy is hyperthermia combined with concurrent radiochemotherapy. For control group, the neoadjuvant treatment is concurrent radiochemotherapy. T-downstaging rate will be used to evaluate the effectiveness of deep hyperthermia. T-downstaging is defined as the postoperative pathological T stage lower than the original T stage by imaging before treatment.

Enrollment (Anticipated)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (ADULT, OLDER_ADULT)

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
EXPERIMENTAL: Hyperthermia Group
The neoadjuvant therapy is hyperthermia combined with concurrent radiochemotherapy for this group.
Procedure: Deep Hyperthermia
Hyperthermia is a type of treatment in which tumor is heated to as high as 40.5-43℃ to help damage and kill cancer cells with little or no harm to normal tissue.
NO_INTERVENTION: Non-hyperthermia group
The neoadjuvant treatment is concurrent radiochemotherapy, which is standard treatment for LARC according to the guidelines.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.

T-downstaging is defined as the postoperative pathological T stage lower than the original T stage by imaging before treatment.

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
