October 2, 2022 updated by: Mattias Hedman, Karolinska University Hospital

Prediction of Individual Radiosensitivity During Radiotherapy for Breast Cancer Patients, the Role of Genetic and Inflammatory Markers

Non-randomized clinical cohort study investigating if single nucleotide polymorphism (SNP) or inflammatory markers can predict radiosensitivity in breast cancer patients receiving radiotherapy.

Study Overview

Indicates the current recruitment status or the expanded access status.
Recruiting

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

Objectives

  1. To explore if acute radiation response can be predicted in patients, by analyzing a single nucleotide polymorphism (SNP rs1801516) sampled prior to radiotherapy.
  2. If acute radiation response can be predicted in patients, by analyzing genetic and inflammatory markers in blood sampled prior to radiotherapy.
  3. If late side effects from radiotherapy can be predicted in patients, by analyzing genetic and inflammatory markers in blood sampled before and after radiotherapy.
  4. If there is a correlation between genetic and inflammatory markers in blood and patient reported outcome measures (PROM) and quality of life (QoL).
  5. To train an algorithm to correlate the appearance of skin before radiotherapy and the extent of skin reaction to radiotherapy

Outline This study is a non-randomized clinical cohort study. Adults with breast cancer will be invited to participate in the study. Blood will be collected before start of treatment and after radiotherapy is completed. Quality of life (QoL) and symptoms will be assessed before and weekly during treatment, at the end of treatment and after one year. A total of 550 patients is expected to be recruited.

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

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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.
Outcome Measure
Measure Description
Time Frame
Acute radiation dermatitis grading criteria
Time Frame: Before and during treatment and after one year
Acute radiation dermatitis grading criteria according to the Radiation Therapy Oncology Group. Minimum value 1 and maximum value 4, higher value means a worse outcome
Before and during treatment and after one year

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.
Outcome Measure
Measure Description
Time Frame
Quality of life (QoL)
Time Frame: Before and during treatment and after one year
Quality of life determined by European Organisation for Research and Treatment of Cancer questionnaire QLQ-C30

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Anticipated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
